Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a connector housing that can be fitted only to a specific connector housing by attaching some members.

[Prior Art] Conventionally, connector housings have been molded with a specific shape of the fitting portion so that they cannot be fitted with anything other than a predetermined connector housing. However, this method requires an extremely large number of types of molding molds, which is uneconomical.Therefore, housings that can be used with several types of mating connector housings are also used, but when connecting There is also a high risk of mating different connector housings by mistake.

[Purpose of the invention] The purpose of the invention is to eliminate the above-mentioned drawbacks, and to provide a structure that can be used with several types of mating housings, while also being able to be used with a specific connector housing by attaching a guide chip. It is an object of the present invention to provide a connector housing which can be fitted only with the connector housing, which is economically advantageous in mold production, etc., and which is free from the risk of erroneous operation.

[Summary of the invention] The gist of the invention to achieve the above objectives is as follows:
A connector housing in which a mating connector housing is fitted with a sealing member interposed between a terminal accommodating part containing connection terminals and an outer wall portion outside the terminal accommodating part, wherein A guide chip is fixed in which a mounting hole is formed and a stopper for locking the seal member is integrally provided in the mounting hole, and only a predetermined mating connector housing having a shape matching the guide chip is allowed to be fitted. This is a connector housing characterized by the following features.

[Embodiments of the invention] The invention will be described in detail based on illustrated embodiments.

The drawing shows an embodiment of a waterproof connector housing that houses two female connection terminals, and a mating housing is inserted between the terminal housing section 2 in the center of the housing body 1 and the outer wall 3. A mating tongue-shaped connecting terminal is inserted into the female connecting terminal 4 to establish a connection. In this case, a mounting hole 5 is formed in the terminal storage portion 2, and a guide chip 6 as shown in FIG.
is now being inserted. This guide tip 6 has spring-like locking pieces 7 on both sides, and is shown in FIGS.
As shown in FIG. 7, when attached to the housing body 1, the locking piece 7 expands within the housing body 1 and cannot be easily pulled out. This guide chip 6 is provided with two guide grooves 8, and only a mating housing having a convex line that matches the guide grooves 8 can be fitted into the housing main body 1. Further, the guide tip 6 is provided with a stopper 9, and this stopper 9 plays the role of preventing the sealing member 10 inserted between the terminal storage portion 2 and the outer wall 3 from slipping out. Note that 11 is a lock lever for locking with the mating housing body.

In this way, according to this embodiment, the connector housing body 1 can be adapted only to the mating housing having the protruding stripes that match the two guide grooves 8 of the guide chip 6.
Even if the connector housings are the same, the mating connector housing can be selected by attaching a specific guide chip 6. It is economical and can also prevent erroneous operation.

Further, FIG. 8 shows another embodiment, in which the guide tip 6 has one guide groove 8,
When it is fixed to the housing body 1 as shown in FIG. 9, only the protrusions on the mating housing body 1 that match this one guide groove 8 can be used.

[Effects of the invention] As explained above, the connector housing main body 1 according to the invention has a plurality of types of guide chips prepared for one type of housing main body, and any one of the guide chips can be inserted as needed. By selecting and installing the guide chip, only a mating connector housing with a shape that matches the selected guide chip can be used.
This has great advantages both economically and in terms of preventing erroneous operations.

Furthermore, the guide tip also serves as a stopper to prevent the waterproof sealing member from slipping out, ensuring a perfect seal.

[Brief explanation of the drawing]

The drawings show an embodiment of the connector housing according to the present invention, in which Fig. 1 is a front view without a guide chip attached, Fig. 2 is a plan view, Fig. 3 is a right side view, and Fig. 4a is a front view of the guide chip. Fig. 5 is a front view of the guide chip attached to the housing body;
Figure 6 is a cross-sectional view taken along line A-A in Figure 5;
The figures are a sectional view taken along the line B--B in Fig. 5, Fig. 8 is a front view of another guide chip, and Fig. 9 is a front view of the housing body to which this guide chip is attached. Code 1 is the housing body, 2 is the terminal storage part, 3
4 is an outer wall, 4 is a connecting terminal, 5 is a mounting hole, 6 is a guide chip, 7 is a locking piece, 8 is a guide groove, 9 is a stopper, and 10 is a sealing member.
