Is formed.

The holder 30 is made of a synthetic resin material. This is to allow the holder 30 to have a predetermined elastic force, so that the holder 30 is more easily coupled through elastic deformation in the process of being coupled to the two connector (10, 20) assembly. Of course, the holder 30 may be made of other materials, such as silicon or metal.

Hereinafter, the operation of the connector holder and the connector assembly using the same in the present invention having the configuration as described above in detail.

First, a process of assembling the connector assembly will be described. First, the worker positions the through hole 12 ′ of the first connector 10 and the insertion hole 22 of the second connector 20 to face each other. In such a state, when the two connectors 10 and 20 are pushed toward each other, the front end of the first housing 11 is connected to the second housing 21 through the insertion opening 22 of the second housing 21. ) Is inserted into.

In this process, while the guide ribs 23 of the second housing 21 are inserted into the guide grooves 13 of the first housing 11, the two housings 11 and 21 can be accurately coupled. . Of course, since the operator can visually check the position of the guide groove 13 and the guide rib 23, the risk of incorrectly coupling the two housings 11 and 21 is reduced.

At this time, since there is no separate structure for fixing between the two housings (11, 21), the two housings (11, 21) can be easily separated from each other. In this state, the male and female terminals are inserted into the second and first housings 12 and 11, respectively.

Therefore, the holder 30 is coupled to the assembly of the two housings 11 and 21 to fasten the two connectors 10 and 20 to each other. The holder 30 is coupled to the upper surfaces of the two housings 11 and 21, more precisely to the surface on which the guide channel 27 of the second housing 21 is formed. At this time, the front ends of the support bars 36 and 36 'of the two coupling parts 34 and 34' may be connected to the terminal mounting holes 12 of the first housing 11 and the terminal mounting holes of the second housing 21, respectively. To face.

In this state, when the holder 30 is pushed toward the housing assembly, the two coupling parts 34 and 34 'are elastically deformed by a predetermined length in a direction away from the two housings 11 and 21, respectively. This is because the connection bar 31 and the coupling parts 34 and 34 'are configured to be elastically deformed due to their material and shape characteristics.

At this time, the respective wires connected to the terminal are inserted between the doped slits 27 and 37. That is, the worker passes the wire between the tips of the support bars 36 and 36 'of the two coupling parts 34 and 34'.

Further, when the holder 30 is further pushed in the direction of the combination of the two housings 11 and 21, the hook hooks 38 and 38 'formed at the ends of the support bars 36 and 36' are elastically deformed and the It is inserted between the hanger slots 18 and 28. When the hook hooks 38 and 38 'are completely inserted into the hook slots 18 and 28, the hook hooks 38 and 38' are restored to their original shape and are fixed by being hooked to one side of the fixing bars 16 and 26. In this case, the operator adjusts the connection bar 31 to be inserted into the guide channel 27.

In this case, since the two coupling parts 34 and 34 'are fixed to the first and second housings 11 and 21, respectively, the two housings 11 and 21 are also firmly fixed to each other. . In addition, since the support bars 36 and 36 'support one side of each terminal inserted into the two housings 11 and 21, it also serves to prevent the terminal from leaving behind the housings 11 and 21. Done.

Next, the disassembling of the connector assembly is performed in the reverse order of the assembling. That is, the hook hooks 38 and 38 'of the holder 30 are elastically deformed and separated from the hook slots 18 and 28, so that the holder 30 is separated from the housing assembly, and the two connectors 10 20) are separated from each other.

The rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and various changes and modifications can be made by those skilled in the art within the scope of the claims. It is self-evident.

For example, the first connector 10 and the second connector 20 may be a female connector and a male connector, respectively, and the first and second coupling parts 34 and 34 ′ may be the first and second connectors, respectively. It may have various sizes and shapes to correspond to the shape of the two housings (11, 21). In addition, the connecting bar 31, the reference bar 35 and the support bar 36 may be formed in a rod shape having a circular or oval cross section.

In the holder for the connector and the connector assembly using the same according to the present invention as described in detail above, the following effects can be obtained.

In the present invention, since a holder for fastening between the two connectors is provided, it is not necessary to form a separate fastening structure in the connector housing. Accordingly, the volume of the connector housing can be reduced to reduce the weight of the connector assembly, and the space occupied by the connector assembly can be reduced, thereby improving space utilization inside the vehicle.

In addition, in the present invention, the holder not only serves to fasten the two connectors, but also serves as a rear holder for supporting and fixing the terminals inside the two connectors, thereby reducing the number of parts.
