Description

[Detailed Description of the Invention] The present invention relates to a switch device that is used while being fixed to a mounting portion.

Conventionally, when a switch device is used by being fixed to a mounting section, the switch device itself is simply treated as a device that acts as a switch, and the wiring is either fixed with a clamp part separately provided to the mounting section or left as is without fixing it. It was common to turn them.

However, in such conventional switch devices, if the wiring is fixed with clamp parts, there will be problems such as increased costs and reduced workability due to the increase in parts, and if the wiring is not fixed, it will be difficult to route the wiring and Because the wiring moves easily after installation, it is easy to break the wire, especially if there is a moving part on the mounting part or the mounting part vibrates, this problem of wire breakage is likely to occur, and there is also a risk that the moving part may interfere with the wiring. There was a problem.

The present invention has been made in view of these conventional problems, and aims to solve the above problems by allowing the wiring to be fixed as is when the switch device is fixed to the mounting portion.

In order to achieve this purpose, the present invention is a switch device that is used by being fixed to an automobile door lock, in which clamp parts are symmetrically and integrally extended on both sides of a plastic housing that supports the components. and a switch device characterized in that the clamp portion is arranged so that when the housing is fixed to the door lock, the wiring can be elastically clamped between the clamp portion and a part of the door lock, and the housing is fixed to the door lock. When this happens, the clamp part elastically clamps the wiring between it and a part of the door lock to hold the wiring so that it does not move.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

The figures show one embodiment of the present invention, and Figs.
FIG. 3 shows the switch device fixed to the door lock, which is the mounting portion.

The door lock 1 is composed of a base member 11 and three actuating members, a latch member 2, a ball member 3, and a relay member 4, which are mutually engaged and pivotally supported, and the relay member 4 is connected to an operating part such as a handle. Member A is connected.

A switch device 5 is provided on one side wall 12 of the base member 11.

The switch device 5 is intended to detect the state of the latch member 2, which is an operating member, and as shown in FIG.
The contact 7, which is urged in the protruding direction by a spring 51, is held via a holding member 8. The housing 6 and the holding member 8 are made of plastic, which is an insulator, and the contact 7 is made of a conductor. A terminal 52 for transmitting signals via a spring 51, which is also a conductor, is provided. A mounting surface portion 62 is formed at the other end of the housing 6, and wing-shaped clamp portions 63, 63 are formed to protrude laterally on both sides of the mounting surface portion 62 so as to hold the mounting direction of the mounting surface portion 62. Since the housing 6 is made of plastic and extends in the form of wings, the clamping parts 63, 63 have elastic flexibility. The mounting surface portion 62 is provided with an insertion hole 64 for a fastening screw 53 for mounting the switch device 5, and a ground terminal 54 is provided which is fastened together with the screw 53 and connected to the base member 11 of the door lock 1. On the other hand, door lock 1
The latch member 2 itself is electrically connected to the base member 11 by being pivotally supported by the base member 11, and the side surfaces of the latch member 2 are insulated by an insulating film except for the detection setting position.

In the switch device 5, the contactor 7 and the like are assembled into the support part 61, and then the upper surface of the mounting surface part 62 is pressed against the side wall 12 of the door lock 1 as shown in FIG. 4, and the contactor 7 penetrates the side wall 12 and projects inside. After making sliding contact with the side surface of the latch member 2, the screw 53
It is fixed by tightening it. At this time, a signal wiring 55 is connected to the terminal 52, a ground wiring 56 is connected to the ground terminal 54, and the signal wiring 55 is connected to the side wall 12 by one of the clamp parts 63 located above in FIG. The signal wiring 55 and the ground wiring 5
6 are routed along the side wall 12 so as not to interfere with actuating members such as the latch member 2, and are elastically clamped and fixed together with the side wall 12 by a clamp portion 63, and from there outward. Connector 5
7 is connected. The door lock 1 is often set on the opposite side, in which case the switch device 5 itself can be used as is on the opposite side, and the clamp parts 63, 63 that clamp the wirings 55, 56 are interchanged.

In this embodiment, the clamp portion 63 is formed protruding from the mounting surface portion 62 in the vicinity of the screw 53, so that the clamp portion 63 also serves to prevent rotation when the earth terminal 54 is attached.

According to the switch device according to the present invention, when the switch device is fixed to the mounting part, the clamp part simultaneously clamps and fixes the wiring, so the wiring can be fixed very easily, and the wiring can be fixed. There is no possibility of interference with operating members, etc., or disconnection after a long period of time due to movement during use. In addition, since the clamp part is formed integrally and symmetrically with the housing, and is elastically flexible, it can accommodate differences in the thickness of the wiring, and it can also be used with the same member in the opposite direction. Since the number of parts does not increase, there is almost no increase in costs.
