There are many problems, and the work becomes cumbersome.

The present invention solves the above problem and aims to provide an electrical connection device for a vehicle meter that simplifies the electrical wiring at the bottom of the case and improves the work efficiency of the wiring. be.

Hereinafter, a detailed description will be given based on the accompanying drawings, using the same reference numerals for the same parts as in FIG.

In the figure, 1 is a case molded from a synthetic resin such as ABS, and the case 1 houses a meter unit 11 such as a voltmeter and an ammeter. A unit terminal 2 is connected to the meter unit 11 and protrudes from the bottom of the case 1, and the terminal 2 has a threaded portion 8 formed therein. Reference numeral 12 denotes a conductive plate fixed to the bottom of the case 1, and the plate 12 has a socket hole 13 and a unit terminal hole 14 formed therein. Reference numeral 3 denotes an electrical cord, and the cord 3 is provided with a cord terminal 5 holding the end thereof to form a pull-out portion 4.

The cord terminal 5 is fitted onto the unit terminal 2 via a plate 12 and a spring washer 7, and is fixed by screwing a nut 6 onto the threaded portion 8 of the unit terminal 2. 10
1 is a lamp socket connected to an electric cord 9, and the socket 10 is fitted and fixed in a socket hole 13 of a plate 12. Reference numeral 15 denotes a contact piece that is exposed by cutting off a part of the side peripheral surface of the socket 10, and the contact piece 15 is inserted into the socket hole 1 of the socket 10.
3 is brought into contact with the plate 12.

Reference numeral 16 denotes a rib that is integrally formed on the bottom of the case 1 and that engages with a flange portion of the plate 12 to fix the plate 12.

In the above configuration, the connection of the instruments is explained as follows.
While the instrument unit 11 is housed in the case 1, the unit terminal 2 connected to the unit 11 is protruded from the bottom of the case 1, and the lamp socket 10 connected to the electric cord 9 is fitted into the socket hole 13 of the plate 12. contact piece 15 and plate 1
2, and furthermore, the plate 1
The unit terminal hole 14 of No. 2 is inserted into the unit terminal 2, and the rib 16 is formed on the bottom of the case 1.
A cord terminal 5 which engages the flange portion of the plate 12 to fix the plate 12 and holds the end of the electrical cord 3 to form the extraction portion 4.
is inserted into the unit terminal 2, and the nut 6 is screwed onto the threaded portion 8 of the unit terminal 2 via the spring washer 7 to complete the connection.

That is, the present invention connects the instrument unit 11 housed in the case 1 and projects the unit terminal 2 from the bottom of the case 1 by fitting the unit terminal hole 14 of the plate 12 with the lamp socket 10 fitted into the socket hole 13. At the same time, the above plate 1
2 is fixed to the bottom of the case 1, the end of the electric cord 3 is held, and the cord terminal 5 with the extraction part 4 is inserted into the unit terminal 2, and the nut 6 is tightened with a spring washer. By connecting the wire 7 to the screw part 8 of the unit terminal 2, the electrical connection between the lamp socket 10 and the meter unit 11 is completed at the same time as the meter unit 11 is fixed to the case 1 by relaying the plate 12. The socket 10 and the unit 1 can be
1 by connecting them with the plate 12,
One pole of the socket 10 and the unit 11, for example, the ground, can be shared, and the wiring of the electric cords 3 and 9 at the bottom of the case 1 can be simplified.

As shown in this embodiment, the instrument case 1 and the conductive plate 12 are each provided with positioning means, and the positioning means positions the conductive plate 12 on the bottom surface of the instrument case 1, whereby the instrument unit 11 The instrument unit 11 and the lamp socket 1 are placed in a predetermined position with respect to the instrument case 1 by preventing the plate 12 from moving blindly during the operations of screwing and fixing the lamp socket 10 and fitting and fixing the lamp socket 10.
0 can be easily placed.

Therefore, when connecting in a relatively narrow space such as an instrument panel of a meter, by minimizing the wiring of the electrical cords 3 and 9, the wiring work is not complicated and can be simplified. can be done. Further, the plate 12 also allows the lamp to have a heat dissipation function, which has the advantage of preventing thermal deformation of the case 1.

As described in detail above, the present invention has a unit terminal connected to an instrument unit such as a voltmeter or an ammeter housed in a synthetic resin case, which protrudes from the bottom of the case, and a conductive plate having a unit terminal hole and a socket hole. Insert the unit terminal hole into the unit terminal and fix it to the bottom of the case, fit the cord terminal holding the end of the electrical cord into the unit terminal, and screw the nut into the screw part of the unit terminal. and fix the cord terminal to the plate to form an electric path,
Furthermore, by fitting the lamp socket with the contact piece formed into the socket hole and connecting the contact piece and the plate to form an electric path, the electrical connection of the bottom of the meter can be completed at the same time as the meter is assembled. In addition, it has excellent practical effects, such as simplifying the wiring, minimizing the amount of cord lead-out wiring, and making the wiring work more efficient.
