[0002]

2. Description of the Related Art A conventional mounting structure for a meter of this type will be described with reference to FIG.

[0003] A conventional mounting structure of a meter 50 shown in FIG. 9 is such that a connector 53 with a wiring member 52 led out of an instrument panel 51 is mounted in a mounting hole provided on the back surface of the meter 50 and then connected to the meter 50. The meter 50 is attached to the instrument panel 51 by inserting a tapping screw 55 into the integrated mounting hole 54 and screwing the tapping screw 55 into a screw receiving portion 56 of the instrument panel 51.

[0004] In order to remove the meter 50 from the instrument panel 51, the operation in the reverse order of the above-described mounting order is performed.

[0005]

However, the conventional mounting structure requires two steps of mounting the connector 53 on the meter 50 and screwing the meter 50 on the instrument panel 51. In this case, two steps, which are the same as those in the case of attachment, were required, and workability was poor.

In addition, in the case of the conventional mounting structure, the wiring member 52 led out from the inside of the instrument panel 51 must have an extra length to some extent for the mounting operation and the removing operation, resulting in waste and cost increase. Will be invited.

Accordingly, the present invention provides a meter mounting operation,
An object of the present invention is to provide a mounting structure of a meter that can perform a detaching operation in one step and can reduce cost by eliminating waste of wiring members.

[0008]

According to the meter mounting structure of the present invention, a mounting hole is provided on the rear side of the connecting conductor in a state where the connecting conductor is exposed and an engaging recess is provided above the connecting conductor. A meter provided with an insertion / removal guide groove disposed above, a connector main body which can be inserted / removed into / from the mounting hole, a connector pin which is arranged at one end of the connector main body, and which comes into contact with a connection conductor of the meter; A wiring member arranged on the other end of the connector pin and connected to the connector pin, one end of which is fixed to the upper surface of the connector main body, and the free end side is vertically displaceably facing the other end of the connector main body, and A connector having a displacement piece projecting from an engagement projection engaged with an engagement recess of the meter; a fitting portion detachably fitted to the other end of the connection connector; and an arrangement of the meter. Area A mounting portion which is mounted in a fixed state, and an insertion / removal guide piece which can be inserted / removed into / from an insertion / removal guide groove of the meter protruding from the fitting portion along the upper side of the connection connector toward one end thereof. And an operation unit that is rotatably supported in the up-down direction at the other end side of the insertion / removal guide piece and that is exposed above the meter with the connector attached to the meter, and an operation of the operation unit. And an operation piece having a pressing portion for displacing the displacement piece to disengage the engagement projection from the engagement recess of the meter and pressing a rear side of the meter. It has.

[0009]

According to the meter mounting structure described above, when mounting the meter, the fitting portion of the insertion / removal operation body is fitted to the other end side of the connection connector, and the mounting portion is located above the meter placement area. In this state, the meter is pushed in such that the insertion / removal guide groove of the meter is guided by the insertion / removal guide piece of the insertion / removal operation body, and the connector main body of the connection connector enters the mounting hole. With this, the connector pin of the connection connector with the wiring member contacts the connection conductor of the meter, and the engagement protrusion projecting from the upper surface of the displacement piece of the connection connector engages with the engagement recess of the meter, This meter is fixed in place, the work of attaching the meter to the connector can be completed in one process, and there is no need to operate any wiring material, so the length of the wiring material can be minimized. it can.

In order to remove the meter, the operation section of the operation piece exposed above the meter provided on the insertion / removal operation body is vertically rotated. By this operation of the operating portion, the pressing portion displaces the displacement piece to release the engagement of the engaging convex portion with the engaging concave portion of the meter, and also connects the meter by pressing the rear side of the meter. Since the meter is detached from the connector, the work of removing the meter from the connector can be completed in one step.
