BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector case for housing and waterproofing a connector.

[0002]

2. Description of the Related Art A waterproof connector having a waterproof structure is widely used as a connector provided at a location where water is applied. For example, in an engine room of an automobile, a waterproof connector mounted on a body side is widely used. However, since the waterproof connector has a waterproof structure, its cost is unavoidably high. For this reason, a non-waterproof connector not having a waterproof structure is actually used in a portion which is not considered to be exposed to water.

[0003]

However, even in such a portion, if water is splashed by mud splash or the like, water that has entered the inside of the connector may cause a short circuit or corrosion of the terminal. For this purpose, the disadvantage can be solved by adopting a means for easily protecting the non-waterproof type connector from water without using an expensive waterproof type connector.

Therefore, according to the first aspect of the present invention, it is possible to easily prevent the connector from being splashed with water and to connect the connector.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. 1 to 6 for a connector case applied to a connector used in an engine room of an automobile. As shown in FIG. 1, the inside of a bottomed cylindrical case body 1 formed by integral molding of plastic is a connector accommodating chamber for accommodating a pair of fitted male and female connectors 20 (see FIG. 5). ). The rear end of the case body 1 is provided with an opening 3, and a cover 6 is provided to cover the opening 3.

An outer surface of the case body 1 is provided with a mounting portion 14 which is mounted on a fixing bracket projecting like a tongue along a mounting surface (not shown) on the body side (see FIGS. 3 and 4). The mounting portion 14 is formed to have a gate-shaped cross section, and has an inner side formed with a locking hole 15 into which a fixing bracket can be inserted. It can be inserted at an appropriate position in the inside. In the center of the mounting portion 14, a lock piece 16 that locks by engaging with the inserted fixed bracket is provided.
Project into the locking hole 15. A pair of left and right lock projections 13 are formed on the lower surface of the rear end of the case body 1 to engage with lock pieces 10 described later.

A pair of left and right mounting brackets 17 are formed so as to project from the front end of the inner surface of the case body 1 toward the housing opening 3. As shown in FIG. 6, the mounting bracket 17 has a pair of left and right locking pieces 18 formed to protrude forward from the base end, and a gap between the base upper surface of the locking pieces 18 and the top face of the case body 1. Is provided with a guide piece 19 so that a connector to be housed therein can be attached.

A guide receiving plate 4 extends rearward at the center of the lower surface of the housing opening 3 opened in the case body 1, and a lid 6 is attached to the upper surface of the housing opening 3 by a cord-like piece 5 so as to be openable and closable. Have been. The lid 6 has a shape that covers the housing hole 3, and an annular ridge 7 that fits inside the housing opening 3 is provided on the inner surface thereof so as to close along the inner surface of the housing opening 3. Have been. A drawer 8 through which the electric wire W is inserted is cut out on one side of the lid 6, and a guide piece 9 is provided around the drawer 8. Also,
A pair of left and right lock pieces 10 having lock holes 11 for engaging and locking with the lock projections 13 are provided at the tip of the lid 6. On the inner surface of the lid 6, a pair of pressing pieces 12 projecting into the case body 1 are formed.

The connector mounted in the connector case of this embodiment will be briefly described. As shown in FIG. 5, in this connector 20, both male and female connectors each fixed to the end of the electric wire W are fitted, and a mounting piece 22 is provided on the upper part of the male connector 20a. . The mounting piece 22 is adapted to be fitted to the above-described fixing bracket on the body side. As shown in FIG. 6, the cross section is formed in a gate shape from the upper surface of the male connector 20a.
The inside is formed as a locking hole 22a into which the locking piece 18 can be inserted. When this mounting piece 22 is inserted into the locking piece 18, it is guided by the outer surface side of the guide piece 19 and abuts on the base end so that the male connector 20 a is mounted on the mounting bracket 17.

The operation when the connector 20 is mounted in the connector case 1 of this embodiment thus configured and the connector case is fixed to the body will be described.

The integrated male and female connectors 20 are inserted through the accommodation opening 3. At this time, as shown in FIG. 6, the locking hole 22a of the mounting piece 22 of the male connector 20a is
8, the entire male connector 20 is moved forward until it is guided by the guide piece 19 and abuts on the base end, and the connector 20 is securely attached to the case body 1.

Next, the fork 5 is bent and the lid 6 is pressed against the accommodation opening 3. At this time, the annular ridge 7 is fitted into the accommodation opening 3 and attached. Then, the lock projection 13 is engaged with the lock hole 11 and the cover 6 is fixed in a state where the cover 6 covers the storage opening 3. At this time, the guide piece 9 and the guide receiving plate 4 form a cylindrical shape, which serves as a guide portion for drawing in the electric wire W, and also prevents water from outside from directly entering the case body 1. Further, the distal end surface 12a of the holding piece 12 presses the rear surface of the accommodated female connector 20b, and
Even if not fully inserted, both connectors 20
Is pushed out until it sufficiently engages with the locking piece 18 and is disposed at a predetermined position.

The electric wire W connected to the connector 20 is guided by the guide receiving plate 4 and drawn out. Then, the mounting portion 14 is inserted into the bracket on the body side, and the lock piece 1 is inserted.
6 are engaged and fixed to the bracket of the body. In addition,
The connector 20 may be attached by attaching the male connector 20a to the case body 1 and then fitting the female connector 20b to the male connector 20a.

As described above, in the connector of this embodiment, the space between the housing port 3 and the lid 6 and the drawer port 8 for inserting the electric wire W are not waterproof, but are temporarily exposed to water. In the case or when water is splashed from the bottom or the side of the case body 1, the waterproof function is exhibited. In particular, since this connector case has a simple structure formed by integral molding of plastic, a waterproof function can be exhibited at a lower cost than a waterproof connector having a complicated waterproof structure.

Further, in this embodiment, the connector 20 is provided to be attached to the fixing bracket on the body side.
Is used as the mounting bracket 17 that can be mounted as it is, so that it can be used without changing the configuration of the conventional connector.

Further, even if the connector 20 is connected to the case body 1
Even if the insertion is not enough when housed inside,
The connector 20 is pressed forward by the holding portion 12 of the lid 6, and the mounting piece 22 can be securely mounted on the mounting bracket 17. Further, when the retaining piece 18 is housed in a poorly housed state in which the mounting piece 22 does not fit, the holding portion 12 abuts on the connector 20 so that the lid 6 cannot be closed. You can know that there is.
