Description

Background of the Disclosure

1. Field of the Disclosure

[0001] The present invention relates generally to a structure of a connector, and more particularly to an easy-to-assemble connector that can be effortlessly used to provide an electrically conductive connection.

2. Description of the Prior Art

[0002] A conventional structure of a connector is shown in FIG. 16, which includes a male connector 50 and a female connector 60. An electrically conductive connection of power and signals can be established by connecting the male connector 50 and the female connector 60. The female connector 60 is provided with a plurality of cone-shaped bores 61. Each of the cone-shaped bores 61 has a wide end and a narrow end, wherein a blocking opening 611 with a smaller diameter is formed in a direction toward the narrow end, and a plurality of inner slots 612 are recessed into a surface toward the wide end. A plurality of signal terminals 62 are installed in the cone-shaped bores 61, wherein each of the signal terminals 612 has a plurality of elastic claws 621 extending at an end toward the corresponding blocking opening 611. The elastic claws 621 are arranged in an annulus manner that an end of each of the elastic claws 621 approaches each other to form an insertion port 622. In addition, each of the signal terminals 62 has a plurality of positioning blocks 623 which are received in the inner slots 612 of the corresponding cone-shaped bore 61. The signal terminals 62 are inserted into the cone-shaped bores 61 from a rear side of the female connector 60. Since the female connector 60 has a casing 63 provided on the rear side thereof, it is not easy to insert the signal terminals 62 within the narrow space of the casing 63, especially when there are many signal terminals 62 going to be assembled in this limited space. Therefore, the conventional structure has the disadvantage that it is not easy to be assembled. The defect rate of assembling female connectors 60 can be increased if the signal terminals 62 are further required to have electric wires connected thereto. On the other hand, while connecting the male connector 50 and the female connector 60, all of the signal poles 51 of the male connector 50 will press against the insertion ports 622 of the elastic claws 621, and it will require considerable force to force all of the elastic claws 621 to open. If the number of the signal terminals 62 is more than twenty, the conductive connection of the connectors will be difficult to establish by bare hands.

[0003] In light of this, the inventor has been engaged in manufacturing, developing, and designing related products for many years. After detailed design and careful evaluation of the above-mentioned objectives, a practically useful invention has finally come up.

Summary of the Disclosure

[0004] The above-mentioned disadvantages of the conventional techniques are technical problems that the present invention aims to solve by providing an easy-to-assemble connector.

[0005] The present invention provides a connector, which includes a first main body, a plurality of power hole terminals, a plurality of signal hole terminals, and a glue. The first main body has a front seat and a rear case, which are integrally formed, wherein the front seat has a flat portion, and the rear case has a receiving space recessed therein. The first main body has a plurality of power insertion holes and a plurality of signal insertion holes, wherein the power insertion holes and the signal insertion holes go through the front seat, communicating the flat portion and the receiving space. The signal insertion holes are straight holes of a same diameter. The power hole terminals are fixedly provided in the power insertion hole, respectively. Each of the signal hole terminals has a straight rod of a same outer diameter, and a connecting tube connected to an end of the straight rod, wherein an outer diameter of the connecting tube is less than the diameter of the straight rod, and an electric wire is connected to an end of the connecting tube opposite to the straight rod. The straight rods are respectively located in the signal insertion hole. Junctions of the connecting tubes and the electric wires are located in the receiving space. The glue fills the receiving space of the rear case, and fixes the connecting tubes and the electric wires.

[0006] In an embodiment, the connector further includes a second main body. The second main body is provided with a plurality of power pole terminals and a plurality of signal pole terminals. The second main body has a casing formed to surround the power pole terminals and the signal pole terminals; the second main body fits around the front seat of the first main body with the casing thereof. The power pole terminals are inserted into the power hole terminals. The straight rods of the signal hole terminals are fixed to the signal insertion holes at different positions, whereby the signal pole terminals are inserted into the signal hole terminals at different timings.

[0007] In an embodiment, a number of the signal hole terminals equals a number of the signal pole terminals, which is between ten and thirty.

[0008] In an embodiment, the first main body is provided with a ring groove at the front seat, and a water stop fits into the ring groove, wherein the water stop is adapted to contact an inner wall of the casing.

[0009] In an embodiment, each of the signal hole terminals is provided with a round hole at an end thereof facing the flat portion. A crown spring is restricted in each of the round holes. Each of the round holes has a small diameter opening formed at an opening thereof, wherein the small diameter opening has a smaller diameter, and blocks the corresponding crown spring. Each of the crown springs has a plurality of elastic sheets formed at a middle segment thereof, wherein the elastic sheets are arranged inward, and are adapted to electrically contact the corresponding signal pole terminal.

[0010] In an embodiment, each of the crown springs has a long neck ring and a short neck ring formed at two ends thereof, wherein the long neck ring and the short neck ring have different lengths. Each of the crown springs is placed into the corresponding round hole either the long neck ring first or the short neck ring first. If it is the long neck ring first, the corresponding elastic sheets are closer to the flat portion of the front seat; if it is the short neck ring first, the corresponding elastic sheets are farther from the flat portion of the front seat.

[0011] In an embodiment, the front seat has a fill slot recessed in a direction of the receiving space. The connecting tubes of the signal hole terminals are provided at the fill slot. The fill slot is filled with a cyanoacrylate glue, wherein the cyanoacrylate glue binds the first main body and the connecting tubes first, and then the glue covers the cyanoacrylate glue to completely fill the receiving space.

[0012] In an embodiment, the front seat is provided with a covering member at the flat portion, and the covering member is provided with a plurality of through holes corresponding to the signal insertion holes. An outer diameter of the through holes is less than an outer diameter of the signal hole terminals.

When the covering member covers the front seat, the surrounding rings go into the corresponding signal insertion holes, pushing the corresponding signal hole terminals to proper depths in the corresponding signal insertion holes.

[0015] The signal hole terminals all go into the signal insertion holes from the side of the front seat where the flat portion is provided, restricting the straight rods in the signal insertion holes. Furthermore, the junctions of the connecting tubes and the electric wires are located in the receiving space, which is then filled with the glue to fix the signal hole terminals. Such design could ease the difficulty in inserting the signal hole terminals and connecting the electric wires inside the very limited receiving space. Therefore the signal hole terminals could be easily assembled. This is the first main objective of the present invention.

[0016] The signal insertion holes are straight holes of the same diameter, which allows more signal insertion holes to be provided in the same volume, whereby more signal hole terminals could be installed therein. Or, in embodiments having the same number of signal insertion holes, the diameter of the signal insertion holes could be increased, which would relatively ease the difficulty in making the signal hole terminals. Moreover, the size of the connector could be decreased. This is the second main objective of the present invention.

[0017] The signal insertion holes of the first main body are straight holes of the same diameter, and are inserted by the straight rods of the same outer diameter. With such design, the outer diameter of the signal hole terminals could be increased without needing to enlarge the overall size of the connector or changing the number of the signal hole terminals. Therefore, the crown springs could be accommodated in the round holes of the signal hole terminals. The high elasticity and high electrical conductivity of the elastic sheets would reduce the resistance for inserting the multiple signal pole terminals into the signal hole terminals at the same time. Hence, the first main body and the second main body could be easily assembled.

[0018] Other objectives, advantages and novelties of the present invention will be more evident from the following detailed description and the related accompanying drawings.

Detailed Description

[0020] To help the examiner to better understand and know the purposes, features, and effects of the present invention, the present invention is illustrated in detail below. Please refer to the brief descriptions of the drawings along with the following descriptions.

[0021] First, please refer to FIG. 1 and FIG. 2. An easy-to-assemble connector includes a first main body 10, a plurality of signal hole terminals 20, a glue 30, and a second main body 40. The first main body 10 has a front seat 11 and a rear case 12 which are integrally formed. The front seat 11 has a flat portion 111. The rear case 12 has a receiving space 121 recessed therein. Furthermore, the first main body 10 has a plurality of power insertion holes 112 and a plurality of signal insertion holes 113, wherein the power insertion holes 112 and the signal insertion holes 113 pass through the front seat 11. All of the power insertion holes 112 and the signal insertion holes 113 communicate the flat portion 111 and the receiving space 12. The signal insertion holes 113 are straight holes of a same diameter. Straight holes with the same diameter allow more signal insertion holes 113 to be provided in a certain volume, whereby there can be more signal hole terminals 20 to be provided therein. Or, in embodiments having the same number of signal insertion holes 113, the diameter of the signal insertion holes 113 could be increased, which would relatively lower the difficulty in making the signal hole terminals 20. Moreover, the connector could be made smaller. A plurality of power hole terminals 13 are respectively provided in the power insertion holes 112.

[0022] Each of the signal hole terminals 20 has a straight rod 21 and a connecting tube 22 connected to an end of the straight rod 21. The straight rods 21 of the signal hole terminals 20 have a same outer diameter. An outer diameter of the connecting tubes 22 is less than that of the straight rods 21. Each of the connecting tubes 22 has an end opposite to the corresponding straight rod 21, wherein said end of each of the connecting tubes 22 is connected to an electric wire 23. The straight rods 21 are respectively located in the signal insertion holes 113, and junctions of the connecting tubes 22 and the electric wires 23 are located inside the receiving space 121. With the above design, the signal hole terminals 20 can be easily manufactured at a low cost. The signal hole terminals 20 all go into the signal insertion holes 113 from a side of the front seat 11 where the flat portion 111 is provided, whereby the straight rods 21 are restricted in the signal insertion holes 113, and therefore the junctions of the connecting tubes 22 and the electric wires 23 are located in the receiving space 121. The steps of assembling the connector are explained below with the reference of FIGS. 3, 4, and 5. The signal hole terminals 20 enter the signal insertion holes 113 located at the flat portion 111 with the electric wires 23 taking a lead, whereby the signal hole terminals 20 pass through the first main body 10 from the front seat 11 to the rear case 12. Then, by pulling the electric wires 23, the connecting tubes 22 and the straight rods 21 of the signal hole terminals 20 could be successfully inserted in the signal insertion holes 113. The straight rods 21 could be further pushed to make the signal hole terminals 20 and the flat portion 11 flat. These assembling processes could be performed manually or automatically. In this way, the first main body 10 and the signal hole terminals 20 are relatively positioned. Furthermore, such a design could ease the difficulty in inserting the signal hole terminals 20 and connecting the electric wires 23 in the very limited receiving space 121. Whereby, the signal hole terminals 20 could be easily assembled, especially when there are ten to thirty signal hole terminals 20 are going to be installed in a small-sized connector, the advantage of inserting the signal hole terminals 20 through the flat portion 11 of the first main body 10 could be further evident. After that, the glue 30 is used to fill the receiving space 121 of the rear case 12, wherein the glue 30 fixes the connecting tubes 22 and the electric wires 23. As a result, the signal hole terminal 20 could be effectively fixed, and the junctions of the connecting tubes 22 and the electric wires 23 could be more water-resistant. Therefore, the present invention is not only easy to assemble, but also durable and water-proof.

[0023] As shown in FIGS. 5 and 6, the second main body 40 is provided with a plurality of power pole terminals 41 and a plurality of signal pole terminals 42. The second main body 40 has a casing 43 formed around the power pole terminals 41 and the signal pole terminals 42. The second main body 40 fits around the front seat 11 of the first main body 10 with the casing 43, and the power pole terminals 41 are inserted into the power hole terminals 13. The number of the signal hole terminals 20 equals the number of the signal pole terminals 42, which is between ten and thirty. Furthermore, the first main body 10 has a ring groove 114 provided at the front seat 11, and an water stop 14 fits in the ring groove 114, wherein the water stop 14 abuts against an inner wall of the casing 43, whereby to connect the first main body 10 and the second main body 40, establishing an electrically conductive connection.

[0024] Another effect of the present invention can be comprehended through FIGS. 2 and 6. Each of the signal hole terminals 20 has a round hole 211 provided at an end thereof toward the flat portion 111, wherein the round hole 211 has a crown spring 24 restricted therein. The round hole 211 of each of the signal hole terminals 20 has a small diameter opening 212, of which a diameter is less than that of other parts of the round hole 211. The small diameter opening 212 blocks the crown spring 24. The crown spring 24 has a plurality of elastic sheets 241 formed at a middle segment thereof, wherein the elastic sheets 241 are arranged inward. The elastic sheets 241 of the crown springs 24 are adapted to electrically contact the signal pole terminals 42. Based on the above descriptions, the signal insertion holes 113 of the first main body 10 are straight holes of the same diameter, and are inserted by the straight rods 21 of the same outer diameter, whereby the outer diameter of the signal hole terminals 20 could be increased without needing to enlarge the overall size of the connector or changing the number of the signal hole terminals. In this way, the crown springs 24 can be easily accommodated in the round holes 211 of the signal hole terminals 20. The high elasticity and high electrical conductivity of the elastic sheets 241 would reduce the resistance for inserting the multiple signal pole terminals 42 into the signal hole terminals 20. Therefore, the first main body 10 and the second main body 40 could be easily assembled.

[0025] Another effect of the present invention can be comprehended through FIGS. 7 and 8. The signal hole terminals 20 go into the signal insertion holes 113 located on the flat portion 111 with the electric wires 23 thereof. By pulling the electric wires 23 and pushing the straight rods 21, the straight rods 21 are restricted within the signal insertion holes 113, and the junctions of the connecting tubes 22 and the electric wires 23 are located within the receiving space 121. A pushing tool A is further used to push against the flat portion 111 of the first main body 10 so that part of the signal hole terminals 20 is positioned as flat as the flat portion 111 is. The pushing tool A has a plurality of protrusions A1 formed thereon, and the protrusions A1 enter the signal insertion holes 113, whereby part of the signal hole terminals 20 is positioned at positions deeper into the corresponding signal insertion holes 113. As a result, the straight rods 21 of the signal hole terminals 20 can be fixed in the signal insertion holes 113 at different depths. After that, the glue 30 is used to fill the receiving space 121 of the rear case 12 to fix the signal hole terminals 20 effectively. In this way, the signal pole terminals 42 of the second main body 40 could be inserted into the signal hole terminals 20 at slightly different timings, whereby to disperse the resistance which would be encountered while inserting the signal pole terminals 42 into the signal hole terminals 20 at the same time. Hence, the first main body 10 and the second main body 40 could be effortlessly connected to complete an electrical conductive status. As shown in FIG. 9, each of the crown springs 24 has a long neck ring 242 and a short neck ring 243 formed at two ends thereof, wherein lengths of the long neck ring 242 and the short neck ring 243 are different. Each of the crown springs 24 could be placed into the corresponding round hole 211 either the long neck ring 242 first or the short neck ring 243 first. When it is the long neck ring 242 first, the elastic sheets 241 will be closer to the flat portion 111 of the front seat 11; when it is the short neck ring 243 first, the elastic sheets 241 will be farther from the flat portion 111 of the front seat 11. While connecting the second main body 40 to the first main body 10, part of the signal pole terminals 42 will force the elastic sheets 241 of the corresponding crown springs 24 to open first. Another part of the signal pole terminals 42 will go into their corresponding crown springs 24 slightly later, which could disperse the resistance encountered while simultaneously inserting the signal pole terminals 42 into the signal hole terminals 20. In other words, the purpose of effortlessly connecting the first main body 10 and the second main body 40 could still be achieved in this way.

[0026] As shown in FIG. 10, the front seat 11 has a fill slot 115 formed in a direction of the receiving space 121, and the connecting tubes 22 of the signal hole terminals 20 are provided in the fill slot 115. The fill slot 115 is filled with a cyanoacrylate glue 31. Since the cyanoacrylate glue 31 flows and dries quickly, the cyanoacrylate glue 31 could easily fill spaces between the connecting tubes 22. In other words, the cyanoacrylate glue 31 will bond the first main body 10 and the connecting tubes 22 first, whereby the signal hole terminals 20 could be prevented from being moved again, which would increase the yield rate of products. After that, the glue 30 will be used to cover the cyanoacrylate glue 31 to fill the receiving space 121 completely. As a result, the structures of the present invention would be easy to assemble, and the combination would be steady and firm.

[0027] As shown in FIGS. 11 and 12, the water stop 14 fits around the front seat 11 of the first main body 10, and a covering member 15 is provided at the flat portion 111 of the front seat 11. The covering member 15 and the front seat 11 together hold the water stop 14 in therebetween. Furthermore, the covering member 15 is provided with a plurality of through holes 151 corresponding to the signal insertion holes 113. A diameter of the through holes 151 is less than the outer diameter of the signal hole terminals 20. When the covering member 15 covers and engages with the front seat 11, the covering member 15 would correspondingly push the signal hole terminals 20 into the signal insertion holes 113, whereby the signal hole terminals 20 could be easily positioned at the same time. As shown in FIGS. 13 and 14, each of the signal hole terminals 20 has a round hole 211 provided at an end facing the flat portion 111, wherein one of the crown springs 24 is accommodated in the round hole 211. At this time, each of the crown springs 24 is not fixed by the corresponding signal hole terminal 20, but is stopped by the covering member 15 from leaving the corresponding round hole 211. If any one of the crown springs 24 is damaged or has elastic fatigue, the crown spring 24 could be conveniently replaced after removing the covering member 15, without needing to throw away the whole connector. Since the crown springs 24 are replaceable when necessary, the durability of the connector could be greatly enhanced. In addition, as shown in FIG. 15, for part of the through holes 151, a periphery of each is respectively surrounded by a surrounding ring 152. Each of the surrounding rings 152 protrudes into a relative inner interior of the covering member 15. Furthermore, when the covering member 15 covers and engages with the front seat 11, the surrounding rings 152 go into the corresponding signal insertion holes 113, pushing the corresponding signal hole terminals 20 to proper depths in the corresponding signal insertion holes 113. As a result, the straight rods 21 of the signal hole terminals 20 could be fixed to the signal insertion holes 113 at different depths so that the signal pole terminals 42 of the second main body 40 could be inserted into the signal hole terminals 20 at slightly different timings. This design could disperse the resistance encountered while inserting the signal pole terminals 42 into the signal hole terminal 20 at the same time.

[0028] In summary, the invention has achieved a breakthrough in structural design, and provides an improved invention. Furthermore, the present invention also has industrial applicability and inventive steps. The invention has not been published in any publications, and therefore is novel.
