Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a waterproof connector in which a terminal is inserted into a housing chamber of a housing with waterproofness.

[0002]

2. Description of the Related Art Conventionally, as a waterproof connector of this type, for example, in U.S. Pat. No. 4,626,692, a terminal is inserted into a housing and locked, and an inner wall of the housing is connected to an electric wire connected to a rear end of the terminal. There is disclosed a device in which a self-healing gel seal member is interposed therebetween, and the gel seal member secures the seal between the inner wall of the housing and the electric wire. According to this waterproof connector, the pitch between terminals can be reduced as compared with a waterproof connector in which a waterproof rubber plug is individually fitted and sealed to each wire as disclosed in JP-A-8-1763. Therefore, the waterproof connector can be made more compact. In addition, since the gel seal member has self-healing properties, it can be assembled by a simple operation of penetrating the terminal connected to the electric wire through the gel seal member, inserting the terminal into the housing, and locking the housing. Therefore, it is not necessary to use a special waterproof terminal, and a non-waterproof terminal used for a normal connector can be used as it is, thereby reducing costs. In addition, since it is not necessary to close unused holes with a plug or the like as in other seal members, workability is also good in that respect and contributes to cost reduction.

On the other hand, for example, in Japanese Patent Application Laid-Open No. Hei 9-232030, a terminal is inserted into a housing chamber of a housing to be primarily locked, further secondary locked by a secondary locking member, and connected to a rear end of the terminal. There is disclosed an electric wire that is sealed with a family seal-shaped sealing member. If the terminal is double-engaged with the housing in this way, it is possible to reliably prevent the terminal from falling off the housing. In addition, if the terminal is not inserted to the proper position in the accommodation chamber, the secondary lock member cannot lock the terminal, so that it is possible to detect the half mounting of the terminal.

[0004]

With respect to the waterproof connector using the gel seal member as described above, the seal between the inner wall of the housing and the electric wire is further improved to ensure reliable waterproof under all conditions. It is eager to secure.

The present invention has been made in view of such a point. An object of the present invention is to form a housing by an outer housing and an inner housing inserted into the outer housing, and to allow the terminal to pass therethrough. By compressing the gel-like sealing member between the two housings, the gel is brought into close contact with the periphery of the electric wire to greatly improve the sealing property of the terminal.

By the way, a retainer is used as a means for locking the terminal to the housing. However, in order to lock the retainer to the terminal, a certain operation such as pushing by hand is required.

Accordingly, a further object of the present invention is to provide a retainer which is pulled by the inner housing during the process of inserting the inner housing into the outer housing when the retainer is used as the terminal locking means. It is an object of the present invention to compress the gel seal member and lock the terminal with the retainer with one touch.

In some cases, the waterproof connector is provided with a connection-side seal member for closing a gap with the mating connector. When the mating connector is removed for inspection or the like, for example, due to a frictional force or the housing. The connection side seal member may fall off due to the negative pressure generated by expansion of the space therebetween. Therefore, a further object of the present invention is to prevent the falling off by locking the connection side seal member using a retainer.

Further, the waterproof connector may be used in an environment that receives, for example, high-pressure washing water. At that time, the gel-shaped sealing member is exposed to high-pressure washing water and the like, and is damaged, thereby impairing the sealing property. There is a risk. Therefore,
It is a further object of the present invention to protect the gel seal member from high-pressure washing water or the like by covering the outside of the gel seal member with a cover, thereby ensuring the sealability.

Further, the present invention utilizes a self-healing property of the gel-shaped sealing member to provide a stabilizer outside the terminal, thereby preventing the terminal from being inserted in the housing chamber in a wrong direction. It is a further object to exert the function of prevention.

In this case, if the terminal is not at the proper position in the accommodation room, the retainer cannot move, and half-mounting is detected. Further, since the retainer is connected to the inner housing, the retainer is prevented from dropping from the inner housing, and the cost is reduced by reducing the number of dies and the number of management steps.

[0015] The housing of the waterproof connector according to claim 3 is
In the configuration according to claim 2, a connection-side sealing member that closes a gap with a mating connector is provided on an outer peripheral surface of the outer housing, and a mating member of the connection-side sealing member is provided in the retainer when the entry into the storage chamber is completed. A stopper for locking the end on the side connector side is provided.

With this configuration, the end of the connection side sealing member is locked by the stopper, so that the connection side sealing member does not fall off even if the mating connector is removed.

The housing of the waterproof connector according to claim 4 is
In the configuration of claims 1 to 3, an introduction-side cover member that covers the introduction port in the outer housing is provided.

In this way, even when used in an environment receiving high-pressure washing water, for example, the high-pressure washing water or the like is not blocked by the cover and does not hit the gel seal member, so that the sealing property is not impaired.

According to a fifth aspect of the present invention, there is provided a waterproof connector in which a terminal is inserted into the housing chamber of the housing according to any one of the first to fourth aspects, wherein the terminal includes:
It is characterized in that a locking portion into which the retainer can be fitted is formed only when the terminal is at a regular position in the accommodation chamber.

This waterproof connector has the functions of the first to fourth aspects. However, if the terminal is not at a proper position in the accommodation chamber, the retainer cannot move, and half-attachment is detected. On the other hand, if the terminal is at the proper position in the accommodation chamber, the retainer can move, and this movement locks the retainer to the terminal.

According to a sixth aspect of the present invention, there is provided a waterproof connector in which a terminal is inserted into a housing chamber of a housing according to any one of the first to fourth aspects, wherein a terminal is provided outside the terminal. When inserted into the accommodation chamber of the inner housing, a stabilizer is provided which is fitted into a groove formed in the insertion direction, moves forward, rides over a lance formed in the groove, and is locked to the lance.

Locks to the terminal 70. Also, the outer housing 20
When the mating connector CC is connected to the connector, the connecting portion of both connectors is covered with the connecting cover member 40 and the inside is sealed. Further, since the retainer 13 is connected to the inner housing 10, the retainer 13 is prevented from falling off from the inner housing 10, and the cost is reduced by reducing the number of dies and the number of management steps. Then, as shown in FIG. 9, the mating connector CC is fitted.

Accordingly, in the above embodiment, since the electric wire W of the terminal 70 is sealed by the gel-shaped sealing member 30, the pitch between the terminals can be reduced to make the waterproof connector more compact than when a waterproof rubber plug is used. The workability can be improved by improving the workability, and the cost can be reduced by using the non-waterproof terminal used for the normal connector as it is, and the workability is improved and the cost is reduced by eliminating the need to plug unused holes with plugs etc. Basic effects such as what can be achieved can be obtained, and the sealing performance of the terminal 70 by the gel-shaped sealing member 30 is greatly improved, so that reliable waterproofness can be ensured under all conditions.

The terminal 70 is secured to the housing by means of a so-called housing lance in which a projection provided on the housing is engaged with a recess of the terminal without using a retainer. There is a method in which the protrusion is engaged with a so-called contact lance in which the protrusion is engaged with a recess of the housing, and the present invention includes all the embodiments using these. However, the retainer 1 as in this embodiment
By providing 3, the compression of the gel seal member 30 and the locking of the terminal 70 by the retainer 13 can be performed with one touch. In addition, since the gel-shaped seal member 30 is compressed by using the movement of the retainer 13, the structure of the waterproof connector C is not complicated, and it is possible to prevent connection failure by half-attachment detection while making the connector compact. Moreover, since the retainer 13 is connected to the inner housing 10, the retainer 13 can be prevented from falling off from the inner housing 10, and the cost can be reduced by reducing the number of dies and the number of management steps. it can.

Further, even if the retainer 13 is not provided with the stopper 13b, the connection side seal member 60 can be prevented from falling off by adjusting the fitting strength of the connection side seal member 60, but the stopper 13b is provided as in this embodiment. The end 61 of the connection side seal member 60 is locked by the stopper 13b, so that when the mating connector CC is removed,
For example, it is possible to reliably prevent the connection-side seal member 60 from falling off due to a frictional force or being pulled by a negative pressure generated by expanding the space between the housings.

Further, in a normal use state where there is not much hydraulic pressure, the sealing properties of the terminals and the like can be ensured only by the gel-shaped seal member 30 without providing the introduction-side cover member 50. When the side cover member 50 is provided, even if the side cover member 50 is used, for example, in an environment that receives high-pressure cleaning water, the high-pressure cleaning water or the like is blocked by the cover 50 and does not hit the gel-shaped seal member 30, so that the sealing performance is not impaired.

In the present invention, the terminal is not required to be double-locked for performing the primary locking and the secondary locking with respect to the housing, but the terminal is double-locked as in the present embodiment. If this is the case, it is possible to reliably prevent the terminal 70 from falling off. In addition, if the primary locking is performed by locking the stabilizer 71 outside the terminal 70 to the lance 15 of the inner housing 10, the terminal 70 is placed upside down with respect to the accommodation chamber 11 of the inner housing 10. When it is inserted in the wrong direction, for example, it is hooked on the entrance of the storage chamber 11 and the insertion operation is stopped, so that a so-called reverse insertion prevention function is exhibited. In that case, when the terminal 70 penetrates the gel-shaped seal member 30, the stabilizer 71 that goes out damages the gel-shaped seal member 30, but the wound is closed due to the self-healing property of the gel-shaped seal member 30,
The sealing performance is not impaired.

Further, the present invention relates to the inner housing 10.
Including the embodiment in which only the storage room 11 is opened in front of
In such an embodiment, for example, when the continuity test of the waterproof connector C is performed by inserting the terminal T of the mating connector CC or a test jig having the same shape as this into the insertion port 72 of the terminal 70 as in the related art, The terminal or the like of the mating connector CC may be deformed due to repeated use, and the insertion of the terminal may damage the leaf spring or the like of the terminal 70 of the waterproof connector C. On the other hand, when the test window 16 communicating with the stabilizer 71 is opened on the front surface of the inner housing 10 as in the present embodiment, the terminal of the mating connector CC is inserted into the test window instead of the insertion port 72 of the terminal 70. Part 1
If the terminal 70 is inserted, it comes into contact with the stabilizer 71, so that a continuity test or the like can be performed without damaging the leaf spring or the like of the terminal 70.

When the stabilizer 71 is provided,
The groove 17 may be formed to have a surface oriented in the width direction or the height direction so as to be inserted into the groove 17 and move forward, and accordingly, the groove 17 is cut in the height direction or the height direction from each storage chamber 11. The lance 15 may be formed so as to bend in the width direction or the height direction. However, when the stabilizer 71 is formed to bend in the width direction as in the present embodiment, the lance 15 of the inner housing 10 is Therefore, it is not necessary to provide the inner housing 10 with a bending margin in the height direction, and the height is reduced. Therefore, the waterproof connector C becomes as compact as possible in the height direction.

In this embodiment, the connection side cover member 40 is provided on the outer peripheral side of the outer housing 20 so as to cover the connection portion of the outer housing 20 with the mating connector CC. When the sealing property can be sufficiently secured, the connection side cover member 4
