Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a connector having a butting seal structure.

[0002]

2. Description of the Related Art A waterproof type connector usually has a hermetically sealed structure in which a sealing portion at the time of fitting or fitting of an electric wire is provided by a rubber stopper or an O-ring. For this reason, when a temperature difference occurs inside and outside the connector, a pressure difference occurs inside and outside the connector due to expansion and contraction of the volume of air, so that a phenomenon has occurred in which water enters the connector through the electric wire. Moreover,
Since the connector has a sealed structure, water that has once entered the connector is unlikely to escape outside.

As a result, in the O-ring type waterproof connector, the space (cavity) of each electrode communicates with the minute space of the connector joint. Insulation cannot be maintained, and short-circuits, leaks, and the like occur between the electrodes.

Therefore, as a countermeasure, a soft elastic sheet is provided on the connector joint surface so that the space of each electrode in the minute space of the connector joint is not communicated, and this is used as an abutting surface to abut at the time of connector joining. It has been proposed to achieve a seal between electrodes by adopting a configuration in which a surface seal is performed.

Specifically, for example, as shown in FIG.
The connector 100 includes a first connector 101 having a housing 91 having a fitting protrusion 91a, and a first connector 101 having a fitting protrusion 91a.
a. The second connector 102 includes a housing 12 having a fitting recess 12a that fits into the second connector 102. Housing 91
A space (cavity) 91e for accommodating the female terminal 4 is provided therein. The cable 5 in which the female terminal 4 is crimped is inserted into the cavity 91e, and the insertion port 91f is sealed with a packing 6 covering the outer skin of the cable 5. Then, the female terminal 4 is locked to the housing 91. An insertion opening 91d for inserting the male terminal 3 which is a counterpart of the female terminal 4 is opened in the end surface S1 of the housing 91, and a lock claw 91c for locking the housing 12 is provided on one side surface. The housing 12 is fixed to the hole 12b so that the male terminal 3 penetrates the bottom surface of the fitting recess 12a. On one side surface, a lock hole 12c which is a counterpart of a lock claw 91c for locking the housing 91 is provided. Is provided.

[0006] A seal member 93 made of a substantially flat soft elastic body for sealing the bottom surface S2 of the fitting recess 12a of the second connector 102 by abutting the opposing end surface S1 of the first connector 101 at the time of connector connection. , And the male terminal 3 is mounted so as to penetrate.

[0007] When the first connector 101 and the second connector 102 are connected, as shown in FIG.
1 is pressed against the surface S3 of the seal member 13 to seal the surface, and the housing 91 and the housing 12 are closed.
Is locked by the engagement between the lock claw 91c and the lock hole 12c.

In general, in such a face seal using the abutting surface, the force required for sealing is the product of the seal area and the force per unit area. Since it is necessary to strongly connect the connector, a lock mechanism using the housing as described above is provided.

[0009]

In the face seal at the abutting face, generally, the direction of compression for sealing and the connecting direction of the connector need to coincide with each other. In order to perform sealing, a large force is required at the time of connector connection. Therefore, if the operation of connecting the connectors is repeatedly performed for a long time, the operator may hurt the finger joint or cause tendonitis. Further, the connector may be shipped with an incompletely connected connector, which may result in sealing failure.

In the case where the lock mechanism of the housing is provided on only one side, when the connectors are connected and locked, the connector is in a state of being inclined obliquely, so that the sealing surface cannot be pressed with a uniform force and the bias is generated. This causes a problem that the seal is incomplete.

The present invention has been made to solve the above-mentioned problems of the prior art, and can improve the sealing characteristics, can prevent the occurrence of a short circuit or a leak between the electrodes, and can improve the sealing performance when connecting a connector. An object of the present invention is to provide a connector capable of reducing operating force.
