BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing device for a connector having lead wires for connecting switches of a multifunction steering wheel.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 7, a lead wire connector for connecting switches of a multifunction steering wheel has a taper upper surface 17a on an inner surface of an upper end of a hook plate 17 facing each other. The formed locking protrusion 17b is provided to connect the connector-
18 was placed on the taper upper surface 17a and pressed from above, and the hook plate 17 was spread outward due to its elasticity and held in place.

[0003]

In the above-mentioned prior art, the force applied to the fixed side connector during connection and disconnection work is large, and the fixed side connector comes off during the work in the locking piece shown in FIG. There was something that happened. As a countermeasure, reinforcement ribs were set on the locking piece, or the thickness of the locking piece was increased and the locking dimension was reviewed, but on the other hand, the locking piece became stronger, which hindered connector mounting. However, there is a problem that workability is deteriorated or the locking piece is broken.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and a fixing plate of a steering wheel is provided with a facing wall through which a female connector can be inserted, and one side wall has an upper end. Attach the door part with a thin hinge so that it can be opened and closed freely.
A locking portion for locking the tip of the door portion is provided on the upper portion of the other side wall, a lock plate and a locking concave portion are provided on the door portion, and a lock groove and a locking convex portion of the lock plate are provided on the lower surface of the female connector. , The lock plate of the opened door part is inserted into the lock groove of the female connector to lock the locking convex part to the locking concave part, and the door part is closed and locked to the other side wall. Characterize.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention shown in FIGS. 1 to 6 will be described below. 1 is a steering wheel, 2 is an air bag, 3 is a top cover, 4 is a base plate, and a bracket 7 to which a switch body 6 of a multifunctional switch 5 is fixed is provided at the front end of the base plate 4. It is fixed with a screw 8. 9 is a lead wire from the switch body 6 and is a male connector-
It is connected to 12. Reference numeral 11 is a fixing plate, which is provided at its tip with opposing walls 13a and 13b through which the female connector 15 can be inserted,
The door 14 is attached to the upper end of one side wall 13a so as to be openable and closable by a thin hinge 14a, and the door 14 is attached to the upper part of the other side wall 13b.
A locking portion 13b 'for locking the locking portion 14b at the tip is provided,
The door 14 is provided with a lock plate 14c and a locking recess 14d. Reference numeral 15 is a female connector, and the lock plate 14 is provided on the lower surface.
A lock groove 15a into which the c is inserted and a locking projection 15b are provided. Reference numeral 16 is a back cover.

At the time of mounting, as shown in FIG. 5, the door 14 is opened, the female connector 15 is pushed in the direction of the arrow, the lock groove 15a is inserted into the lock plate 14c, and the locking protrusion 15b is locked.
4d is fitted and locked. Next, the door 14 is rotated in the direction of the arrow, and the elasticity of the side wall 13a is used to lock the locking portion 14b to the locking portion 13b 'of the side wall 13b. Next, the male connector-12 is inserted and connected to the fixed female connector-15.

[0007]

According to the present invention, the fixing plate of the steering wheel is provided with the opposing wall through which the female connector can be inserted,
A door part is attached to the upper end of one side wall by a thin hinge so as to be openable and closable, a locking part for locking the tip of the door part is provided on the other side wall, and a lock plate and a locking recess are provided on the door part. -Providing the lock groove and the locking projection of the lock plate on the lower surface,
Since the lock plate of the opened door portion is inserted into the lock groove of the female connector to lock the locking convex portion in the locking concave portion, the door portion is closed and locked to the other side wall. It is easy to assemble and does not require force, and after assembly, the female connector can be securely held without being fixed in the vertical and horizontal directions.
