Description

[Detailed description of the invention] [Summary] This invention reduces the number of parts by providing a cable fixing part in the connector housing in order to solve the high cost caused by connector covers in the cable structure of connectors for electronic devices, etc. It is something.

[Industrial application field]

The present invention relates to a connector used in electronic equipment such as an electronic computer or an electronic exchange, and particularly relates to a cable clamp structure of the connector.

[Conventional technology]

FIG. 2 is a structural diagram of a cable clamp of a conventional connector.

In FIG. 2, 21A and 21B are connector covers, 22 is a housing, 23 is a screw, 24 is a screw hole, 25 is a cable fixing part, and 26 is a cable.

In a connector in a general electronic device, a cable 26 and a contact embedded in the housing 22 are connected in advance, and the connection part is sandwiched between the connector cover 21A and another connector cover 21B, and the connector cover 21A and the other connector cover 21B are sandwiched. The cable fixing part 25 is clamped with a screw 23 through a screw hole 24 of a cable fixing part 25 provided in another connector cover 21B, and the cable fixing part 25 absorbs an external force that may be applied from outside the connector.

[Problem that the invention attempts to solve]

However, the conventional connector clamp structure uses a connector cover when connecting and fixing the cable and the contacts embedded in the housing, which has the disadvantage of increasing costs.

The object of the present invention is to provide a connector clamp structure that improves the above-mentioned problems.

[Means for solving problems]

Therefore, in the present invention, a plurality of different housings 1 and 2 are provided as shown in FIG. A recess 2a corresponding to the protrusion 5 is provided. Further, the cover 3 covering the end of the cable 4 is made of an external force absorbing material, and the through hole 3 through which the plurality of protrusions 5 passes
The configuration includes a.

[Effect]

The cable 4 and the contacts embedded in the housing 1 are fixed as follows.

That is, the plurality of projections 5 of the housing 1 are inserted into the through holes 3a of the cover 3 covering the end of the cable 4, and then the recesses 2a of the housing 2 are inserted into the projections 5.
to fix the cable 4 to the housing 1.

According to this structure, the external force applied to the cable 4 can be absorbed by the cover 3 and the housings 1 and 2.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1A and 1B.

FIG. 1A is an exploded perspective view of the connector of the present invention.

FIG. 1B is a completed view of the connector of the present invention.

In Fig. 1A and B, 1 and 2 are housings;
3 is a cover, 4 is a cable, 5 is a protrusion (pin),
6 is the connector connection surface, 7A is the tab, 7B is the notch,
8 indicates a belt.

The conventionally used housing is divided into a housing 1 that holds the connector connection surface 6 and a housing 2 that does not hold the connector connection surface 6, and the housing 1 has two pins 5.
Furthermore, a notch 7B for clamping with the housing 2 is provided on the outer side surface of the housing. The housing 2 is provided with a recess 2a corresponding to the two pins 5 provided in the housing 1, and a notch 7B.
A claw 7A is provided at a position corresponding to .

The cover 3 that covers the end of the cable 4 is made of an external force absorbing material, such as a resin such as rubber or nylon, and has two through holes 3a at positions corresponding to the two pins 5 provided in the housing 1. ing. Further, the cover 3 is fixed to the cable 4 using a belt 8.

By having the above configuration, the two pins 5 provided in the housing 1 can be connected to the through holes 3a provided in the cover 3.
, the recesses 2a corresponding to the two pins 5 provided on the housing 2 are aligned with the two pins 5, and the notches 7B provided on the housing 1 and the claws 7A provided on the housing 2 are engaged.

With this configuration, even if an external force is applied from outside the connector, the external force is applied to the two pins through the cover, so the external force is not applied directly to the connector terminal processing section, and the connection is similar to that of conventional technology. Provides stability.

[Effect of idea]

As explained above, according to the present invention, external force from outside the connector can be absorbed without providing a special connector cover, and connection stability performance similar to that of the conventional technology can be obtained.

Therefore, the connector cover can be omitted and costs can be reduced.
