Description

TECHNICAL FIELD

[0001] The present invention relates to the field of electrical equipment, and belongs to a fixing holder of a modular insertion core and a connector.

BACKGROUND

[0002] Fixing frame is used for fixing insertion connection modules, wherein the fixing frame is equipped with a number of different insertion connection modules, which are then inserted into the insertion connection housing and screwed together with it. Here the fixing frame needs to be stable, so that it can withstand the inserting and tensile forces that occur when mounted or disassembled.

[0003] It can be known from CN107925192B that the prior art provides a fixing frame consisting of two mutually hinged half frames, wherein the fixing frame is separated perpendicular to the side walls of the frame, and the hinges are disposed on the fastened end of the fixing frame in such a way that when the fixing frame is screwed on fixing surface, the orientation of the frame body is adjusted such that: the side walls of the fixing frame are perpendicular to the fixing surface and the insertion connection module has a connection mated to the shape of the fixing frame via the fixing device. When the mounting of the modular insertion core is implemented by this way of mounting, as the operator installs the modular insertion core to the correct position during use, it is necessary to install attachments to prevent the frame from rotating, which increases the difficulty of mounting during the mounting process, costs more time in the mounting process and reduces the efficiency. Assembling such a retaining frame is a time-consuming operation. For example, once a module needs to be replaced, such a retaining frame has to be unscrewed and/or unlocked from the plug-in type connector. Other modules that are not intended to be removed at all may fall out of the retaining frame and must be reinserted before the frame halves are screwed together again and/or before the frame halves are clamped together. Before the frame halves can be connected, all modules must be in the positions provided for them at the same time, so that when the frame halves are connected together, they can eventually be fixed in the retaining frame. This makes assembly more difficult.

[0004] It is known from CN10055794C that a fixing frame is also provided in the prior art. The fixing frame has a plurality of wall sections separated by slits on its insertion side, wherein every two symmetrically opposite wall sections form an insertion region for the insertion module; the wall section has window-shaped openings, and protrusions are formed on the narrow sides of the insertion module; and when the insertion module is inserted into the insertion region of the fixing frame, the protrusions stop into the window-shaped openings. In this way, the mounting process consumes less time due to the lack of the step of combining the two frame halves. However, since the fixing frame is implemented mainly by the use of the performance of the material itself to realize the insertion of the insertion core, the reliability of the mounting is mainly achieved by the deformation of the material itself. This method will have higher requirements on the material itself. Since most of the fixing frames are integrally formed by the molds, it is difficult to ensure the consistent performance of each frame during the injection molding process, which will cost more expenses.

SUMMARY

[0005] The purpose of the present invention is to provide a fixing holder of a modular insertion core and a connector which can realize the quick assembly and disassembly of the product and ensure the safety of the product.

[0006] In order to achieve the above purpose, the technical solution adopted in the present invention is: a fixing holder of a modular insertion core, wherein the fixing holder is used for receiving similar and/or different modular insertion cores, wherein the fixing holder includes:

a first frame body provided therein with a cavity for accommodating the modular insertion core, the modular insertion core entering into the cavity provided in the first frame body from the opening direction of the first frame body;

the modular insertion core is fixed in the first frame body by means of a second frame body, wherein the second frame body is detachably connected to the first frame body.

[0007] Further, the present invention also provides a connector comprising a plug and a socket, wherein the plug is to be mated with the socket, and the plug and the socket each include a fixing holder and modular insertion core disposed in the fixing holder, wherein the fixing holder are used for receiving similar and/or different modular insertion cores, wherein the fixing holder includes:

a first frame body provided therein with a cavity for accommodating the modular insertion core, the modular insertion core entering into the cavity provided in the first frame body from the opening direction of the first frame body;

the modular insertion core is fixed in the first frame body by means of a second frame body, wherein the second frame body is detachably connected to the first frame body;

when the plug is mated with the socket, the modular insertion cores disposed in the plug and in the socket are mated with each other by insertion.

[0008] As can be seen from the above technical contents, the beneficial effects of the present invention are: since the modular insertion core is fixed in the first frame body by means of the second frame body, and the second frame body is detachably connected to the first frame body, as can be seen in this case, the first frame body and the second frame body can be two separate components. During the mounting process of the modular insertion core, the second frame body can be connected with the first frame body after the modular insertion core is placed in the first frame body. During the disassembly process, the separation of the first frame body and the second frame body can be simply realized by operating the second frame body with one hand, which improves the work efficiency. In this way, the deformation of the second frame body itself is mainly utilized, and there is no difficulty in the injection molding process, and the second frame body is a sealing member surrounded by a quadrangle, which has a relatively lower difficulty in injection molding. If the first frame body and the second frame body need to be disassembled and assembled with high frequency in the use environment, the material of the second frame body can be replaced with a metal piece, which improves the service life of the second frame body.

[0009] In another implementation, the second frame body includes a first body, a second body and an elastic member, wherein the first body and the second body each include a first leg, a second leg, and a side pressing edge for connecting the first leg to the second leg, wherein the first leg has a first limiting surface, and the second leg has a second limiting surface, wherein the second leg is provided therein with a cavity capable of accommodating the first leg, and the first body and the second body are mounted in the accommodating cavity provided by the first frame body, wherein the first limiting surface of the first leg of the first body and the second limiting surface of the second leg of the second body, and the second limiting surface of the second leg of the first body and the first limiting surface of the first leg of the second body, respectively, form a movable space, wherein an elastic member is deposed in the movable space. In this implementation, by disposing the elastic member in the movable space formed after the first leg and the second leg are mounted, the separation of the leg and the second leg is realized by the deformation of the elastic member. According to the mounting process, during the use, since the second frame body and the first frame body have been mounted as a whole, the user can put the modular insertion core into the cavity provided in the first frame body. In this case, since the modular insertion core needs to be mounted downward into the cavity, the modular insertion core squeezes the second frame body, making the movable space between the first leg and the second leg become smaller, and the elastic member is in a compressed state under the action of the squeezing force. When the modular insertion core continues to move downward to the fixture position, since the modular insertion core and the second frame body are in the case where there is no force acting in the left and right directions on each other at this time, the elastic member returns to its initial state under the state of its own elastic force, thereby enabling the connection of the first frame body and the second frame body. This mounting method is simple, fast and effective, and does not need to rely on the elastic force of the materials of the first frame body and the second frame body themselves to realize the application of functions. In the absence of the specific requirements on materials, there are not much requirements on the materials of the first frame body and the second frame body, which saves the costs.

[0010] The lengths of the first mounting step and the second mounting step are different, such that the mis-insertion of the modular insertion cores during the mounting process can be avoided, thereby improving the safety.

[0017] One skilled in the art will recognize that the various embodiments may be practiced without one or more of the specific details or with other alternative and/or additional methods, materials or components. In other instances, well-known structures, materials, or operations are not shown or described in detail so as not to obscure aspects of the various embodiments of the present invention. Similarly, for purposes of explanation, specific quantities, materials and configurations are set forth in order to provide a thorough understanding of the embodiments of the present invention. However, the present invention may be practiced without the specific details. Furthermore, it is to be understood that the various embodiments shown in the drawings are illustrative representations and are not necessarily drawn to scale.

[0018] A fixing holder of a modular insertion core 2, the fixing holder being used for receiving similar and/or different modular insertion cores, wherein the fixing holder includes: a first frame body 1 provided therein with a cavity where the modular insertion core 2 is accommodated, the modular insertion core 2 entering into the cavity provided in the first frame body 1 from the opening direction of the first frame body 1; the modular insertion core 2 is fixed in the first frame body 1 by means of a second frame body 3, wherein the second frame body 3 is detachably connected to the first frame body 1.

[0019] The structure of the modular insertion core 2 can refer to the sample of Phoenix, wherein the modular insertion cores 2 further comprise a hole-type plug and a pin-type socket, wherein the pin-type socket is mated with the hole-type plug to realize the electrical connection. The hole-type plug and the pin-type socket are respectively mounted in the fixing holders of different modular insertion cores 2, and the connection and disconnection of the circuit are realized by the mating of the hole-type plug with the pin-type socket.

[0020] The material of the second frame body 3 is the same as or different from the material of the first frame body 1. In most use cases, the material of the first frame body 1 is plastic. The material of the second frame body 3 can be the same as that of the first frame body 1, that is, it can be a plastic material. The material of the second frame body 3can also be a non-plastic material, such as metal. The material of the second frame body 3 can be selected from different materials according to the situation where the first frame body 1 is disassembled therefrom. The second frame body 3 is preferably made of metal material, if it is necessary to use the deformation force of the second frame body 3 per se to realize multiple disassembly of the second frame body 3.

[0021] As shown in FIG. 1 to FIG. 5, in the first implementation, the second frame body 3 includes oppositely disposed pressing portions 4 and supporting portions 5, wherein the pressing portions 4 and the supporting portions 5 are disposed adjacent to each other to form a quadrangular structure member. The mounting direction of the second frame body 3 is the same as the mounting direction of the modular insertion core 2. In this case, after the modular insertion core 2 is mounted into the first frame body 1, the second frame body 3 makes the first frame body 1 and the second frame body 3 clamp together in the same direction.

[0022] The clamping connection between the first frame body 1 and the second frame body 3 is mainly achieved through the following technical solutions: the outer side of the pressing portion 4 is provided with a protruding ear 6 for connecting with the first frame body 1, the first frame body 1 is provided with a mating portion 7 which is to be mated with the protruding ears 6. When the first frame body 1 and the second frame body 3 are connected, the protruding ears 6 are in contact with the mating portion 7. That is, during the implementation process, when the modular insertion core 2 is mounted into the first frame body 1, the second frame body 3 enters the first frame body 1 along the same direction as the mounting direction of the modular insertion core 2. During the mounting process, the protruding ears 6 are in contact with the mating portion 7, so as to realize the connection between the second frame body 3 and the first frame body 1. Since the second frame body 3 is located above the modular insertion core 2, the second frame body 3 can fix the modular insertion core 2 in the first frame body 1.

[0023] The positions of the protruding ears 6 and the mating portion 7 can be adjusted according to the actual situations, not limited to the protruding ears 6 being disposed in the second frame body 3 and the mating portion 7 being disposed in the first frame body 1, as long as the connection between the first frame body 1 and the second frame body 3 can meet the requirements of the present invention.

[0024] The first frame body 1 therein is provided with a mounting step for mounting the modular insertion core 2, and both ends of the modular insertion core 2 are provided with a clamping portion 9 that is to be clamped with the mounting step. The matching of the clamping portion 9 and the mounting step is used to realize the connection between the modular insertion core 2 and the first frame body 1, wherein the clamping portion 9 is a protruding component protruding from the outer surface of the modular insertion core 2, and the protruding component is disposed into the mounting step in the first frame body 1, wherein the shape of the mounting step is consistent with the shape of the protruding component.

[0025] In order to realize the mounting of the modular insertion core 2 and the first frame body 1, generally, the mounting steps provided in the first frame body 1 are typically one or more sets of oppositely disposed mounting steps. When a user needs to connect multiple circuits, the number of the mounting steps can be increased in the first frame body 1. Since the modular insertion core 2 is a standardized module, when multiple mounting steps are set in the first frame body 1, multiple modular insertion cores 2 can be placed. The modular insertion core 2 comprises two types: a hole-type plug and a pin-type socket, and the hole-type plug and the pin-type socket are mated with each other to realize the connection of the circuit. Since generally a plurality of modular insertion cores 2 are disposed in one first frame body 1, in order to prevent the disorder of the circuit, it is necessary to set up a device to prevent the circuit connection error during the implementation process, so as to prevent irreparable losses resulting from the wrong connection of the circuit. In this scenario, each set of the mounting steps has a first mounting step 10 and a second mounting step 11, wherein the lengths of the first mounting step 10 and the second mounting step 11 are different. Since the dimensions of the mounting steps in each set are configured to be different, in the case of mis-insertion, the modular insertion core 2 cannot be put into the first frame body. In this way, mis-insertion during the wiring process can be avoided. The inside of the first frame body 1 is provided with a raised portion 12, and the raised portion is used for realizing the fixing and guiding functions of the casing of the modular insertion core 2. Meanwhile, the raised portion 12 is provided in the present solution for the purpose of saving materials. In the actual use process, the plane where the raised portion is located can also be set as the plane that is parallel to the front end surfaces of the first mounting step 10 and the second mounting step 11, which can also achieve the purpose of the present invention.

When the core-pulling type is adopted, that is, when the accommodating portion 25 and the first frame body 1 are as a complete entirety. An opening 28 smaller than the movable space is provided at the upper position of the movable space, and the opening 28 is used to realize the mounting of the elastic member 15.

[0029] When the accommodating portion 25 is open type, a movable or rotatable cover plate can be provided on the first frame body 1, for the purpose of preventing the elastic member 15 from popping out during the squeezing process, while providing the first body 13, the second body 14 and the elastic member 15 with a restraining force in the upper and lower direction to prevent them from being separated from the first frame body 1.

[0030] The side pressing edge 18 is located on the outer side of the first frame body 1, wherein the side pressing edge 18 can move along the guiding bosses 27 provided on the first frame body 1 during the disassemble of the modular insertion core 2, and the part where the side pressing edge 18 is mated with the first frame body 1 is provided with the guiding groove 26. There is at least one guiding boss 27, and the number of the guiding grooves 26 is consistent with the number of the guiding bosses 27.

[0040] The previous description of the present invention is provided to enable any person skilled in the art to practice or utilize the present disclosure. Various modifications to the present invention will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other variations without departing from the spirit or scope of the present disclosure. Thus, the present invention is not intended to be limited to the examples and designs described in the specification, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0041] As can be seen from the above technical contents, since the modular insertion core 2 is fixed in the first frame body 1 by means of the second frame body 3, and the second frame body 3 is detachably connected to the first frame body 1, as can be seen in this case, the first frame body 1 and the second frame body 3 can be two separate components. During the mounting process of the modular insertion core 2, the second frame body 3 can be connected with the first frame body 1 after the modular insertion core 2 is placed in the first frame body 1. During the disassembly process, the separation of the first frame body 1 and the second frame body 3 can be simply realized by operating the second frame body 3 with one hand, which improves the work efficiency. In this way, the deformation of the second frame body 3 itself is mainly utilized, and there is no difficulty in the injection molding process, and the second frame body 3 is a sealing member surrounded by a quadrangle, which has relatively lower difficulty in injection molding. If the first frame body 1 and the second frame body 3 need to be disassembled and assembled with high frequency in the use environment, the material of the second frame body 3 can be replaced with a metal piece, which improves the service life of the second frame body 3.

[0042] In another implementation, the second frame body 3 includes a first body 13, a second body 14 and an elastic member 15, wherein the first body 13 and the second body 14 each include a first leg 16, a second leg 17, and a side pressing edge 18 for connecting the first leg 16 to the second leg 17, wherein the first leg 16 has a first limiting surface 19, and the second leg 17 has a second limiting surface 20, wherein the second leg 17 is provided therein with a cavity capable of accommodating the first leg 16, and the first body 13 and the second body 14 are mounted in the accommodating cavity 21 provided by the first frame body 1, wherein the first limiting surface 19 of the first leg 16 of the first body 13 and the second limiting surface 20 of the second leg 17 of the second body 14, and the second limiting surface 20 of the second leg 17 of the first body 13 and the first limiting surface 19 of the first leg 16 of the second body 14, respectively, form a movable space, wherein an elastic member 15 is disposed in the movable space .

According to the mounting process, during the use, since the second frame body 3 and the first frame body 1 have been mounted as a whole, the user can put the modular insertion core 2 into the cavity provided in the first frame body 1. In this case, since the modular insertion core 2 needs to be mounted downward into the cavity, the modular insertion core 2 squeezes the second frame body 3, making the movable space between the first leg 16 and the second leg 17 become smaller, and the elastic member 15 is in a compressed state under the action of the squeezing force. When the modular insertion core 2 continues to move downward to the fixture position, since the modular insertion core 2 and the second frame body 3 are in the case where there is no force acting in the left and right directions on each other at this time, the elastic member 15 returns to its initial state under the state of its own elastic force, thereby enabling the connection of the first frame body 1 and the second frame body 2. This mounting method is simple, fast and effective, and does not need to rely on the elastic force of the materials of the first frame body 1 and the second frame body 3 themselves to realize the application of functions. In the absence of the specific requirements on materials, there are not much requirements on the materials of the first frame body 1 and the second frame body, 3 which saves the costs.

[0043] The lengths of the first mounting step 10 and the second mounting step 11 are different, such that the mis-insertion of the modular insertion cores 2 during the mounting process can be avoided, thereby improving the safety.

[0044] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which the present invention pertains can make various changes and modifications without departing from the spirit and scope of the present invention. Thus, the protection scope of the present invention should be determined from the claims.
