Abstract

PROBLEM TO BE SOLVED: To provide a terminal connection structure simplifying connection work, reducing the number of parts, and ensuring low manufacturing cost because there is no need for mounting a connector on a wiring board and connecting the wiring of a wiring board to a terminal provided for a case via the connector. SOLUTION: This structure is constituted so as to wire a wiring board 3 inside a case 1 and electrically connect a terminal 2 provided in the case 1 to a terminal 5 of the wiring of the wiring board 3. In this case, a planar or linear conductor 7 having its elasticity is connected to the terminal 2 at one end, and the other end thereof is pressure-contacted by means of an elastic force to a conductive part 6 formed at the end edge of the wiring board connected to the wiring terminal 5.

[0003]

According to the above connection structure, the number of parts is increased and the connection work is complicated, so that the manufacturing cost becomes high.

An object of the present invention is to provide a terminal connection structure for an electronic device that solves such a problem.

[0005]

In order to solve the above object, the present invention provides a wiring board inside a case and electrically connects terminals provided in the case to the wiring of the wiring board. In the terminal connection structure of the electronic device, the other end of the elastic plate-shaped or linear conductor whose one end is connected to the terminal is elastically connected to the conductive portion which is connected to the wiring and is formed on the edge of the wiring board. It is characterized by being pressed by force.

According to the above configuration of the present invention, the wiring board is incorporated in the case, and the other end of the elastic plate-like or linear conductor having one end connected to the terminal provided in the case is provided in the case. The terminals are electrically connected to the wiring of the wiring board by pressing the conductive portions formed on the edges of the board with elastic force.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an example of a terminal connection structure of the present invention applied to an electronic device of a water heater, for example.

In FIG. 1, reference numeral 1 denotes a case of an electronic device for a water heater, for example, a case 1 provided with a pair of terminals 2 (only one is shown in the figure) connected to the body of the water heater. There is. Reference numeral 3 denotes a wiring board on which a circuit for remotely controlling the water heater main body is formed. On one edge of the wiring board, concave portions 4 are formed, for example, at two places. For example, a pair of conductive parts 6 and 6 connected to 5 are provided. The conductive portions 6, 6 are formed, for example, by sticking a copper foil or by covering the stuck copper foil with solder. Reference numeral 7 is a plate-like or linear conductor (only one is shown in the figure) made of, for example, phosphor bronze or the like and having one end connected to the terminals 2 and 2 exposed inside the case 1 along the case 1. And the other ends thereof are pressed against the conductive portions 6, 6 formed in the recesses 4, 4 by elastic force.

According to the structure of the above-described embodiment, the other ends of the pair of elastic plate-shaped or linear conductors 7, one end of which is connected to the terminal 2, are fitted into the recesses 4 and 4, and the elastic force thereof is applied. The terminals 2 are securely connected to the circuit of the wiring board 3 by being pressed against the conductive portions 6, 6 formed in the recesses 4, 4.

[0010]

As described above, according to the present invention, it is not necessary to mount the connector on the wiring board and connect the wiring of the wiring board to the terminal provided on the case through the connector, and the wiring board is incorporated in the case. Since this is sufficient, the connection work can be simplified, the number of parts can be reduced, and the manufacturing cost can be reduced.
