[Industrial use]

The present invention relates to a switch device for an automobile door, and in particular, a switch structure for detecting an open state of an automobile trunk door has a structure in which a (+) and (-) plate terminal is installed inside an outer case to generate a short circuit between terminals. It relates to a switch device for a car door that can prevent the.

[Private Technology]

In general, the door switch for the car is on / off operation according to the opening and closing of the door to display it on the instrument panel by the driver to easily recognize this to prevent the safety accident in accordance with the opening of the door in advance.

4 shows a switch device of a trunk door for a conventional vehicle.

Referring to FIG. 4, the conventional trunk door switch has a structure in which the switch operating mechanism is opened in the open bracket 50, and the push rod 40 is elastically supported by the open bracket 50 and the spring 42. The lower side of the push rod 40 has a positive plate terminal 44 connected by a connecting line 48 to be fixed by a screw 52. If the open bracket 50 is installed on the open bracket 50 and the open bracket 50 is fixed to the vehicle body, the (-) plate terminal 46 is grounded to the vehicle body.

Therefore, when the pressing force acts on the upper part of the push rod 40, the push rod 40 and the (+) plate terminal 44 are lowered together and the contact device is separated from the (-) plate terminal 46 grounded in the vehicle body. Becomes "off". In addition, when the pressing force acting on the push rod 40 is released, the push rod 40 is returned to its original position by the elastic force of the spring 42 so that the (+) plate terminal 44 of the open bracket 50 It is connected to the negative plate terminal 46 installed at the bottom, the switch device is in the "on" state.

[Problems with Prior Art]

The switch device of the trunk door for a conventional vehicle described above has a structure in which the (+) and (-) plate terminal parts are exposed to the outside, so that a short occurs due to moisture penetration from the outside to the (+) and (-) plate terminal parts. have. In addition, due to the shock and vibration received during opening and closing of the trunk door and the high and high motion of the (+) plate terminal, the switch device has a problem in that the contact portion of the connecting line is easily disconnected, causing failure.

[Problem to Solve Invention]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide a switch device for a door for an automobile that can secure the fixing of the terminal portion of the switch device and prevent the disconnection and short circuit of the connection line. .

It is still another object of the present invention to provide a switch device for a door for an automobile in which various parts of the switch device are installed inside the case to improve appearance.

Means to solve the problem

The present invention has been made in view of the above-described conventional problems, the switch device of the vehicle door according to the present invention is a switch device of the vehicle door for detecting the open state of the automobile door, the (+) plate terminal The lower case is provided with a (+) plate terminal insertion groove to be inserted and fixed: One end is installed on the (+) plate terminal to be installed in the lower case and provided with a washer at a certain position in the movement direction to provide the (+) play A push rod which is elastically supported by the rod terminal and the elastic member and reciprocates from the contact position with the (-) plate terminal to the release position; (-) The terminal insertion groove is provided so that the plate terminal can be inserted and fixed, and the upper cover is formed with a through hole formed so that the push rod can be penetrated, and the upper cover and the outer case are detachably coupled. It features. Preferably, the upper cover is provided with a hook hook portion, the lower case is coupled to the engaging groove is formed so that the upper cover and the outer case can be detachably coupled.

EXAMPLE

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing an outer case of the trunk door switch device according to the present invention, Figure 2 is a perspective view showing the operation of the trunk door switch device according to the invention, Figure 3 is a trunk door switch device is installed in the vehicle body The cross section in a state is shown.

Referring to Figure 1, the outer case is composed of the upper cover 12 and the lower case 10, the door switch is the lower case 10 is installed in the operating part inside the lower case in a box shape with the upper open ( On the bottom of 10), a (+) terminal insertion groove 18 into which the (+) plate terminal 22 can be inserted is formed. The (+) terminal insertion groove 18 is preferably formed in the bottom portion of the lower case 10 can be securely fixed to the (+) terminal plate 22, but to the bottom of the lower case 10 It can be installed spaced apart from a certain distance. A plurality of locking grooves 16 are formed in the upper portion of the lower case 10 so that the locking hook portion 14 of the upper cover 12 to be described later can be inserted and fixed.

The upper cover 12 has a (-) terminal insertion groove 20 is formed so that the (-) plate terminal 24 can be installed, and a plurality of hook hooks 14 having a bottom inclined portion on the lower surface The upper cover 12 is installed to be detachably coupled to the lower groove 10 engaging groove 16. In addition, the upper cover 12 is provided with an extension that protrudes to one side when combined with the lower case, and the through portion 38 is formed in the extension to cover the upper upper cover 12 by a riveting operation, etc. It can be fixed firmly.

2 and 3, the operation portion of the door switch device is formed in a cylindrical form, the push rod 26 and the push rod 26 is provided with a locking washer 28 at a predetermined position in the Shanghai east direction, and the push rod 26 It is made up of an elastic member 30 to elastically support the, and the spring guide 32 is installed on the (+) plate terminal 22 to serve as a guide of the spring that is the push rod 26 and the elastic member 30 have.

A through hole 36 is formed in the spring guide 32 so that the lower portion of the push rod 26 is inserted through the spring guide 32. In addition, when the upper portion of the push rod 26 is inserted into the through hole 36 formed in the upper cover 12 by the elastic member 30, and a force acts on the upper portion, the push rod 26 is a lower spring guide. It can be moved elastically up and down through the through hole 39 of the (32).

Referring to the effects of the present invention configured as described above are as follows.

If the trunk door is closed while the trunk door switch is installed in the vehicle body, the push rod 26 of the door switch descends, and accordingly, the in-vehicle dashboard connected to the (-) plate terminal 24 grounded on the vehicle body is disconnected therefrom. The lamp installed in the phase is “off”. That is, when the trunk door is closed, the door switch is kept in the "off" state.

In addition, when the trunk door is opened, the pressing force acting on the push rod 26 is released and the push rod 26 descending accordingly is disposed between the catch washer 28 and the positive plate terminal 22. Return to its original position by the elastic force of the (+), (-) plate terminals 22, 24 are connected to the lamp installed on the dashboard of the vehicle "on".

The operation part of the switch in which this operation is performed is installed inside the outer case and protected from external moisture, and the (+), (-) plate terminals 22 and 24 are firmly fixed to the outer case and the vehicle body. In addition, the door switch can prevent the disconnection of the connection line due to the switch operation because the movable portion is limited to the up and down operation of the push rod 26.

[effect]

According to the present invention as described above, the (+), (-) terminal portion is inserted into the outer case can not only prevent the short phenomenon due to moisture penetration, it is possible to fix the (+), (-) terminal portion Since the terminal is prevented from flowing when opening and closing the door, it is possible to prevent the disconnection of the connecting line.
