Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a contact mechanism used for a vehicle lock mechanism or the like.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 1 and 2, a rotor a made of synthetic resin and a coil spring b on the rotor a.
It is known that the rotary contact d is attached to the fixed contact c so as to be elastically attached to the fixed contact c.

[0003]

However, the above-mentioned known device has a difficulty in assembling the rotary contact d. Since the rotating contact point d is constantly pressed by the coil spring b in the direction of pulling out, it must be assembled so as not to come off, which is troublesome. The present invention has been made to a means for mounting the one corresponding to the rotating contact d very easily.

[0004]

Therefore, according to the present invention, the rotating body 1 made of synthetic resin, the pair of left and right parallel engaging grooves 5 and 5 formed in the rotating portion of the rotating body 1, and the engaging member. Ditch 5, 5
Of the groove inner surfaces of the outer groove inner surfaces 7, 7 and the engaging stepped portions 8, 8 and the cut-and-raised pieces 12, 12 formed of a thin metal plate and cut and raised outward on the tip side. Contact part 1 for connecting the bases of the bayonet legs 10 and 10 and the two-forked bayonet legs 10, 10.
1. The contact member 9 has a contact member 9 and the contact member 9, the insertion legs 10 and 10 of which are pressed into the engaging grooves 5 and 5 so that the cut-and-raised pieces 12 and 12 are engaged with the engaging step portion. 8, a contact mechanism used for a vehicle lock mechanism or the like engaged with 8, and a contact mechanism used for a vehicle lock mechanism or the like in which a coil spring 16 is provided between the contact member 9 and the rotating body 1 in the above. Further, in the above, the contact member 9 is a contact mechanism used for a vehicle lock mechanism or the like in which a spring piece 17 that elastically contacts the rotating body 1 is integrally provided.

[0005]

An embodiment of the present invention will be described with reference to the drawings.
Reference numeral 1 denotes a rotating body made of synthetic resin, which has a base 2 and a shaft 3
Fit the different diameter part of and fix it. A pair of left and right parallel engagement grooves 5 and 5 are formed on the front end side 4 of the rotating body 1. The engagement grooves 5 and 5 are grooves that are long in the radial direction of the shaft 3 and penetrate vertically, and the inner side surface 6 of the groove is formed as a flat wall surface on both sides from the beginning to the outside groove inner surface 7. The engagement step portion 8 that travels inward is provided. The position of the engagement step portion 8 is an intermediate position in the groove direction of the engagement groove 5. The groove width of the engagement grooves 5 and 5 is formed to be considerably larger than the thickness of the contact point member 9 engaged with the engagement grooves 5.

The contact member 9 is formed by punching a thin metal plate with a press and then bending it into a U-shape. The contact members 9 have bifurcated insertion legs 10 and 10 on both sides. A contact portion 11 is formed at the base of 10. Cut-and-raised pieces 12 and 12 that are cut and raised outward are formed on the tip ends of the two-pronged insertion legs 10 and 10, respectively. Since the tip ends of the two-pronged insertion legs 10 and 10 are engaged with each other when they are applied to the upper surfaces of the engagement grooves 5 and 5, if the contact portion 11 is pushed in with a fingertip in that state, the cut-and-raised pieces 12 and 12 are parted. Is elastically fitted and inserted, and then, when the cut-and-raised pieces 12 and 12 pass through the engaging step portions 8 and 8, they spread and engage with the "snap".

The contact portion 11 is formed with a contact portion 13 which bulges outward (projects upward in the figure). A round groove 14 is formed at an intermediate position between the engaging grooves 5 and 5. Reference numeral 15 is a round bar 15 remaining in the center of the round groove 14. The base portion of the coil spring 16 is fitted into the round groove 14, and the contact point member 9 is elastically lifted by the protruding head portion 17. Figure 9
10 shows a second embodiment, in which the coil spring 16 of the first embodiment is stopped to form an integral spring piece 19, and 18 is a punched hole formed when the spring piece 19 is formed.
The operation is the same as in the first embodiment.

[0008]

[Operation] Next, the operation will be described. The contact member 9 of the present invention is formed by punching a flat thin metal plate by pressing. Further, the rotating body 1 of the present invention is formed by injection molding of synthetic resin. Then, the base portion of the coil spring 16 is engaged with the round groove 14 of the rotating body 1, and the tips of the bifurcated insertion legs 10 and 10 of the contact member 9 are brought into contact with the upper surfaces of the engagement grooves 5 and 5,
When the contact member 9 is strongly pressed against the elastic force of the coil spring 16 with a fingertip, the cut-and-raised pieces 12, 12 of the bifurcated insertion legs 10, 10 are pressed.
Is once contracted inward when passing through the engaging step portions 8 and 8 of the engaging grooves 5 and 5, and spreads and engages when passing through the engaging step portions 8 and 8. In this state, the outside of the tip side 4 and the contact portion 11
Since a considerable gap is formed with the inner surface of the contact member 9, the contact member 9 elastically moves in and out by the coil spring 16 and becomes a good contact member. Since the coil spring 16 is not used in the second embodiment, it can be simply pushed in as it is, which is simpler and the cost is lower.

[0009]

As described above, the known one has a difficulty in assembling the rotary contact member d. Since the rotating contact member d is constantly pressed by the coil spring b in the direction of pulling it out, it must be assembled so as not to come off, which is troublesome. However, according to the present invention, the rotating body 1 made of synthetic resin, the pair of left and right parallel engaging grooves 5 and 5 formed in the rotating portion of the rotating body 1, and the inner surfaces of the engaging grooves 5 and 5 are formed. A bifurcated insertion leg 10 having engaging step portions 8 and 8 formed on the inner surfaces 7 and 7 of the outer groove, and cut-and-raised pieces 12 and 12 which are formed of a thin metal plate and which are cut and raised outward on the tip side. 10 and the bifurcated leg 10,
The contact member 9 has a contact portion 11 for connecting the base portion of the contact member 10, and the contact member 9 has the insertion legs 10 and 10 pressed into the engaging grooves 5 and 5 to insert the cut and raised piece 12. , 12 are contact mechanisms used in a vehicle lock mechanism or the like which is engaged with the engaging step portions 8, 8, the tips of the forked insert legs 10, 10 of the contact member 9 are engaged with the engaging groove 5, When it comes into contact with the upper surface of 5 and is pushed hard with a fingertip, the cut-and-raised piece 1 of the forked insert legs 10 and 10
2 and 12 contract once inward when passing through the engaging step portions 8 and 8 of the engaging grooves 5 and 5, and expand and easily engage when passing through the engaging step portions 8 and 8, and once engage. After it is done, it does not come off, so it is easy to insert and handle. In addition, in the above, since the coil spring 16 is provided between the contact member 9 and the rotating body 1, the contact member 9 is elastically lifted, and the operation is good. Further, in the above, since the contact member 9 is integrally provided with the spring piece 19 which elastically contacts the rotating body 1, the assembly is simpler and the cost is lower.
