Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of Invention] (Industrial field of application) The present invention relates to a connector used for connecting wire harnesses or the like to each other or connecting a wire harness or the like to a receptacle on the side of an apparatus, The present invention relates to a connector having an improved retainer accommodating chamber for accommodating a retainer used for surely inserting an electric connector into a housing.

(Prior Art) This type of connector accommodates a pair of male and female electrical connectors for electrically connecting electric wires with each other in each housing, and the electrical connector is securely inserted into the housing. Some retainers are fitted into the housing.

Various types of connectors using this retainer have been proposed in the past. For example, the type described in Japanese Utility Model Publication No. 63-28865 is known.

This connector is a bulkhead as shown in Figures 17 and 18.
A plurality of connector accommodating chambers 61 partitioned by 60 are opened in the housing 62, and when the electrical connector 64 clamped to the tip of the electric wire 63 is inserted into these connector accommodating chambers 61,
The locking arm 66 on the housing 62 side is engaged with the rear end of the electric contact portion 65 of the electric connector 64 to prevent the electric connector 64 from coming off.

After inserting the electrical connector 64, the retainer 67 is inserted from the rear of the housing 62, and the front end of the retainer 67 is connected to the electrical connector 64.
By pressing the stabilizer 68, it is possible to prevent incomplete insertion of the electrical connector 64 and prevent rattling of the electrical connector 64.

The locking engagement pieces 69 provided on both sides of the retainer 67 engage with the engaging portions 70 on the housing 62 side in a state where the retainer 67 is completely inserted.

(Problems to be solved by the invention) However, in the conventional connector as described above, the retainer 67 inserted between the electric wire 63 in the housing 62 and the inner wall surface of the upper plate 71 slides on the electric wire 63 and the inner wall surface. However, there is no guide member for the retainer 67 because it is inserted into the housing 62.

For this reason, when the retainer 67 is inserted, the workability of the insertion is poor due to the obstruction of the electric connector or the electric wire that is inserted in advance, and the stabilizer 68 is inserted in the inserting direction of the retainer 67.
However, there is a problem in that the rigidity cannot be sufficiently given because the pressure is pressed.

The present invention has been proposed in order to solve such problems, and an object thereof is to improve the workability when inserting the retainer and to provide a connector capable of giving the retainer sufficient strength. To do.

After being inserted into the retainer housing chamber 45, the retainer accommodating chambers 45 on the upper and lower stages are inserted from the rear opening 55, and the engagement piece 29 engages with the locking claw 56 in a completely inserted state. At this time, the protruding end 24a of the insertion portion 24 of the retainer 15 is connected to the electrical connector 36.
Since the stabilizer 48 of the
36 is securely housed in the housing chamber 35, and the locking arm 41 is engaged with the locking hole 43.

When the female connector is inserted into the male connector configured as described above, the electric contact portion 37 and the electric contact portion 5 are fitted to each other to electrically connect the electric wires 3 and 52, and at the same time, the female housing. The locking piece 20 of and the claw 19 of the male housing are engaged with each other to make a mechanical connection.

The flexible member provided so as to project from both sides of the female housing is a holding piece 57 for attaching the female housing to a housing or the like.

[Effect of device]

As described above, according to the present invention, the connector housing chamber and the retainer housing chamber are independently formed in the housing, so that the retainer can be securely placed in the housing without being obstructed by the electric connector or the electric wire. Because you can insert
Workability and reliability can be improved.

Further, since the partition wall that separates the connector storage chamber and the retainer storage chamber can give the retainer rigidity in the insertion direction, damage to the retainer that occurs during insertion can be prevented.

Further, even if the pitch between the electrical connectors is narrowed due to the miniaturization of the connector and the strength of the locking arm that engages with the connectors is weakened, the decrease in the holding force is reinforced by the improvement in the strength of the retainer, The electric connector can be firmly held in the housing.
