[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector mainly used for connecting a wiring harness for an automobile.

[0002]

2. Description of the Related Art In FIG. 4, reference numeral a denotes a female connector, and b denotes a male connector, each of which has terminal fittings (not shown) which are brought into contact at the time of fitting. A locking arm c is provided on an outer peripheral portion of the male connector b, and a locking projection d is provided on an outer peripheral portion of the female connector a. When the connectors a and b are fitted, the locking arm c is used for locking. Engagement with the projection d locks the connection between the connectors a and b (FIG. 4B). In addition, e is a waterproof hood.

In the above-mentioned prior art, when the external force F acts on the locking arm c, the lock is automatically released, and the mating connectors a and b are disengaged to cause poor conduction of the terminal fittings. In some cases, the lock mechanism may be damaged.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and is intended to protect a lock mechanism against an external force F to stabilize the lock function.

[0005]

In order to achieve the above-mentioned object, the present invention comprises a pair of female and male connectors which are fitted with each other. A protective hood surrounding the entire peripheral surface of the body portion is provided at an interval from the body portion, a notch portion is formed in the body portion, and a flexible lock piece is provided corresponding to the notch portion. A configuration is employed in which a locking projection that engages with the flexible lock piece is provided on the outer periphery of the connector.

[0006]

The protective hood shuts off an external force applied to the lock mechanism for holding the female and male connectors together.

[0007]

In FIG. 1, A is a female connector made of a synthetic resin and has a male terminal fitting (not shown) built in the terminal accommodating chamber 1. B is a male connector made of a synthetic resin and has a terminal. A female terminal fitting (not shown) is built in the accommodation room 2. A locking projection 3 is provided on the outer peripheral surface of the male connector B.

In the female connector A, there is a gap G on the outer side of the sleeve 4 for receiving the male connector B, and the entire circumference of the sleeve 4 is extended further forward than the front end of the sleeve 4.
A protective hood 5 surrounding the body is provided. A notch 6 is formed in the body 4 from the front end, and a flexible lock piece 7 having a base 7a is formed between the body 4 and the hood 5 corresponding to the notch 6, and is opposed to each other. A pair of locking holes 8 in the wall
Are formed. The flexible lock piece 7 may be formed integrally with the sleeve 4 by slitting it. Reference numeral 9 denotes a packing holder fitted in the sleeve 4, having a notch 10 at a portion corresponding to the flexible lock piece 7, and a locking projection 11 which engages with the locking hole 8. Have. Therefore, the packing 12 is inserted into the sleeve 4, and then the packing holder 9 is fitted, and the locking projection 11 is engaged with the locking hole 8 and fixed.

In use, the male connector B is fitted into and coupled with the packing holder 9 of the sleeve 4 of the female connector A, and the locking projection 3 is engaged with the flexible locking piece 7 from the cutout 10. To secure the connection (FIG. 3). In addition, 1
Reference numerals 4 and 14 'denote rubber waterproof plugs fixed to the terminal fittings C and C' together with the electric wire W.

The unlocking is performed by a jig (not shown).

[0011]

As described above, the present invention comprises a pair of female and male connectors which are fitted to each other. The female connector is provided with a jacket and surrounds the entire peripheral surface of the jacket. A protective hood is provided at an interval from the body, a notch is formed in the body, and a flexible lock piece is provided corresponding to the notch, and the flexible lock is provided on the outer periphery of the male connector. Since the locking projection is provided to engage with the piece, the protective hood prevents external force from being applied to the locking mechanism, thereby preventing connection failure of the terminal fitting due to inadvertent release of the lock. can configured with fewer continuous wall an outer circumferential surface irregularities of the connector having a locking mechanism by Food
The wire is entangled with the lock mechanism during transportation and storage
When connecting female and male connectors.
Appropriate parts of a series of protective hoods
It can be pinched with fingers and can be used to connect female and male connectors.
Very convenient for joint work.
