CONNECTOR SYSTEM WITH CODING MODULES

Description

[0001] The present invention relates to a connector system. In particular, the present invention relates to coding modules for connector systems, for instance for junction boxes, electrical motors and other electrical devices which may be connected to several cables, each cable corresponding to a different function and/or different voltages, etc.
Therefore, it is necessary for the operator to be able to differentiate cables and connectors with respect to their respective functions and/or voltages. For this purpose, it is known to use a mechanical coding module, which prevents the connection of a connector with another connector which is not its counter connector.
The mechanical coding modules comprising protrusions at different locations of a connector face to be applied on the counter connector, which engage complementary shaped holes in the counter connector, are well known. Such a coding module comprising protrusions is described in EP-A1-0887892. Particularly, in this document, protrusions are elongate in a plugging direction. Therefore, a first connector mechanically matches only with its counter connector.
Mechanical coding modules known from the prior art are directed to connector assemblies. Such connector assemblies are mounted on electrical devices. With the constant increase in requirements for miniaturization and standardisation, it becomes more frequent to use similar connector parts for different functions on the electrical device itself. Therefore, the risk of misconnections has increased.

[0002] A connector system according to the preamble of claim 1 is known from WO 84/04201.

[0003] There is further an increasing need to reduce cost of connector assemblies and to simplify the supply chain of connector parts.

[0004] For this purpose, there is provided a connector system according to claim 1. Such a connector system comprises an electrical device, with at least one respective base, at least one connector assembly having a first connector part and a second connector part, wherein the first connector part and the second connector part are adapted to connect with each other in a connection direction and wherein the first connector part is associated with the respective base on which it mates.
In addition, the connector system comprises a first coding module arranged between the respective base of the electrical device and the first connector part wherein the first coding module prevents the first connector part from mating with any other base than the respective base.
The first coding module comprises first coding elements, preferably identical first coding elements. The respective base and the first connector part comprise a plurality of first locations to receive the first coding elements. The first coding elements are provided on some of the first locations to form a first coding key. The first coding elements can be provided in various locations to define various first coding keys for a plurality of first connector parts.
With those features, it is provided a connector system, which simplifies the supply chain of connector parts. In addition, it prevents a first connector part from mating with any other base than its respective base. Indeed, same first connector parts can be used to form a plurality of connector assemblies. First connector parts are differentiated one from each other by the first coding elements, which are provided according different first coding keys on different first connector parts of the plurality of connector assemblies.
The above connector system allows to provide a connector assembly which will be assembled only to the respective base. The risk of assembly of a connector assembly to the wrong base is reduced. Further, the first coding keys may be made entirely by the connector supplier, reducing the number of actions to be performed by the manufacturer of the device. Therefore, the risk of mishandling by unqualified workers on the device manufacturer side is reduced, and the whole supply chain is improved.

[0005] In some embodiments, one might also use one or more of features defined in dependent claims. The connector system according to dependent claims has the advantage that coding elements and shaped locations to receive coding elements are simple to manufacture.

[0006] Of course, different features, alternatives and/or embodiments of the present invention can be combined with each other in various arrangement to the extent that they are not incompatible or mutually exclusive of others.

[0016] According to a first embodiment of the present invention, the first coding element 7 is a coding pin 7, which is suitable to cooperate with the first coding opening 11, or hole 11, arranged in the face 12 and to be inserted therein. The cooperation between the first coding element 7, respectively first coding elements 7, and the first coding opening 11, respectively first coding openings 11, defines the first coding key.

[0017] Consequently, the respective base and the first connector part 2 mate together when the first coding key of the respective base is complementary to the coding key of the first connector part 2. In addition, such arrangement defines a locating system suitable to define a position of the first connector part 2 with respect to the respective base.

[0018] The second coding element 8 is a coding ridge 8, which is fitted in the second locations 9, particular in the first coding groove 9.

The first connector part 2, provided with at least one coding element 7 in a specific first coding location 11 of the series of first coding locations 11, can mate with a respective base as soon as the respective base comprises a hole located at a corresponding location to the first coding location 11 on the first connector part 2 provided with the coding element 7. However, several coding elements 7 may also be used on the same first connector part 2, for example two coding elements 7. In such case, the first coding key is provided by a suitable number of first coding locations 11 at correct locations on the respective base.

[0023] Figure 2 is a perspective view of a housing of the device 1 provided with connector assemblies according to the present invention and shows such housing of the device 1 with four first connector parts 2, the device 1 having four respective bases. Particularly, on Figure 2, one of the four first connector parts 2 is mated with a second connector part 3, which is its counter part or counter connector.

[0024] The face 12 of the first connector part 2 is applied on its respective base of the device 1. The device 1 may advantageously be an electrical device, like junction boxes or electrical motors.

[0025] First connector parts 2 are mounted onto respective bases by fixation means. In the embodiment shown in Figure 2, the first connector part 2 is fixed to the housing by screws 15 which pass through the hole 14 and a suitable threaded opening in the device 1.

[0026] The first connector part 2 may be a male contact part and the second connector part 3 may be a female part. Obviously, in an alternate embodiment, the first connector part 2 may be a female part and the second connector part 3 may be a male part.

[0027] Figure 3 is a perspective view of the first connector part 2 according to the present invention and shows the first connector part 3 with several second locations 9, designed as first coding grooves 9. In the embodiment shown, the first connector part 3 comprises four first coding grooves 9.

[0028] Figure 4 is a perspective view of the second connector part 3 according to the present invention suitable to be mated with the first connector part 2, as depicted on Figure 3. The second connector part 3 comprises also several second locations 90, designed as second coding grooves 90, which correspond to second locations 9, i.e. first coding grooves 9, provided on the first connector part 2.

[0029] First coding grooves 9 of the first connector part 2 and second coding groove 90 of the second connector part 3 have a particular shape suitable to be fitted with the second coding elements 8. First Coding grooves 9 of the first connector part 2 and second coding groove 90 of the second connector part 3 define second locations 9, 90 for the second coding module 20.

[0030] Preferably, the first connector part 2 and the second connector parts 3 comprise several first coding grooves 9 and several second coding grooves 90. As a consequence, the second coding element 8, for example the coding ridge 8, is fitted in the first coding grooves 9 and the second coding grooves 90 to define the second coding key.

[0031] The second coding element 8 can be provided in different second locations 9, 90 to define various second coding keys for a plurality of first connector parts 2 and a plurality of second connector part 3.

[0032] Advantageously, coding grooves 9 of the first connector part 2 and coding grooves 90 of the second connector part 3 are identical to each other and are facing each other.

[0033] Particularly, the first connector part 2 may be a header and the second connector part 3 may be plug.

[0034] Figure 7 is a perspective view of the second coding element 8 according to the present invention. More specifically, on Figure 7, the second coding element 8 is a coding ridge 8.

[0035] According to a particular embodiment, the coding ridge 8 is a rod with a polygonal section comprising a general rectangular part 81 and a trapezoidal part 82. The trapezoidal part 82 is adapted to be fitted in first coding grooves 9 of the first connector part 2 and second coding grooves 90 of the second connector part 3. Preferably, coding grooves 9 of the first connector part 2, respectively and coding grooves 90 of the second connector part 3, have a dovetail shape.

[0036] When coding ridges 8 are fitted in first coding grooves 9 of the first connector part 2, respectively second coding grooves 90 of the second connector part 3, the portion of coding ridges 8 having the rectangular part 81 is extending outward of first coding grooves 9 of the first connector part 2, respectively second coding grooves 90 of the second connector part 3.

[0037] Figure 5 is a sectional view of the first connector part 2 according to the present invention. Particularly, Figure 4 shows the first connector part 2, in which two coding ridges 8 are fitted in two of its four first coding grooves 9, the portion of coding ridges 8 having a rectangular part section 81 extending outward of first coding grooves 9.

[0038] The first connector part 2 and the second connector part 3 comprise each two coding ridges 8 mated in two different coding grooves 9 of the first connector part 2 . The mating of the first connector part 2 and the second connector part 3 is possible, since coding ridges 8 are not fitted in same coding grooves 9 of the first connector part 2 and coding grooves 90 of the second connector part 3. Indeed, coding ridges 8 of the second connector part 3 are fitted in two coding grooves 90 of the second connector part 3, which do not face coding grooves 9 of the first connector part 2 in which coding ridges 8 are fitted.

[0039] First coding grooves 9 of the first connector part 2, second coding grooves 90 of the second connector part 3 and coding ridges 8 provide the second coding module 20. The location of first coding grooves 9 of the first connector part 2, second coding grooves 90 of the second connector part 3 and coding ridges 8 provide the second coding key.

[0040] Consequently, the first connector part 2 and the second connector parts 3 mate with each other, when the second coding key makes it possible to assemble the first connector part 2 onto the second connector part 3.

[0041] In an embodiment of the invention, the first connector part 2 and the second connector part 3 are each provided with two coding ridges 8 to form a first coding key. The first coding key makes it possible to mate the first connector part 2 and the second connector parts 3 mate with each other as soon as coding ridges 8 of the second connector part 3 are fitted in second coding grooves 90, respectively first coding grooves 9, which do not face the grooves of the first connector part 2, respectively the second connector part 3, in which coding ridges 8 are fitted.

[0042] Indeed, since coding ridges 8 having a rectangular part section 81 extend outward of the first coding grooves 9, respectively second coding grooves 90, the first connector part 2 and the second connector part 3 can not mate with each other, since a mechanical stop surface provided by the portion of coding ridges 8 having a rectangular part section 81 extending outward of the first coding grooves 9, respectively second coding grooves 90, when coding ridges 8 of the first connector part 2 and the second connector part 3 are fitted in first coding grooves 9 and second coding grooves 90, which are facing each other.

[0043] Figure 8 is a sectional view of first connector parts 2 with different second coding keys according to the present invention and shows different possible second coding keys on the first connector part 2. In the shown embodiment, two coding ridges 8 are provided on four different first grooves 9, therefore six possible second coding keys exist.
For example, the number of first coding keys provided between the respective base and the first connecting part 2 is the same as the number of second coding keys, between respectively between the first connecting part 2 and the second connecting part 3,.

[0044] In an embodiment of the invention, n locations may be provided on the connector part, where n is a natural number, n >1, and k coding elements may be provided, where k is a natural number and k≤n. The number of possible coding keys will be therefore

i.e.

[0045] In some other embodiment of the invention, the first connector part 2 and the second connector part 3 may be provided with two coding surfaces. The two coding surfaces increase the number of possible coding keys.

[0046] The two coding surfaces are provided on the housing of the first connector part 2 and the second connector part 3, preferably on opposite surfaces of the housing along the plugging direction X.
Advantages of such features are to use the same coding elements for defining various coding keys, on a first hand, for the connector parts and counter connectors, and; on the other hand, for the connectors and its respective bases.
