BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a large-sized electronic component for a vehicle-mounted electronic control connector which can hold a large-sized electronic component such as a large-sized capacitor or diode with one touch without using a separate fixed component on a terminal board. It relates to the mounting structure.

[0002]

2. Description of the Related Art Vehicles such as passenger cars are equipped with electronic control connectors for electronically controlling various devices.
This connector is composed of a housing, an IC board, a terminal board, and a lid. Small electronic parts such as ICs and resistors are mounted on the IC board by printed wiring, and large electronic parts such as large capacitors and diodes are
It is mounted on a terminal board different from the board.

In the conventional vehicle-mounted electronic control connector,
There are various structures as described below for mounting a large electronic component on the terminal board, but each has its own drawbacks. For example, in the mounting structure shown in FIGS. 19 and 20, with the main body 1 of the electronic component P being held by the dedicated tool 31, the two leads 2 are attached to the terminals 33 integrally provided on the terminal board 32. The leads 2 and the terminals 33 are resistance-welded to each other. In this mounting structure, since the main body 1 of the electronic component P is only placed on the terminal board 32 and is not held, there is a risk that the main body 1 will be vibrated during use and broken. There are various drawbacks in that the positioning of the lead 2 with respect to each terminal 33 is troublesome.

Further, in the mounting structure shown in FIGS. 21 and 22, a saucer 34 having a concave surface corresponding to the shape of the body 1 of the electronic component P is integrally molded with the terminal board 32, and the saucer 3 is formed.
4, the main body 1 of the electronic component P is placed, and the two leads 2 and each terminal 33 are resistance-welded. According to this mounting structure, there is an advantage that the lead 2 of the electronic component P can be easily positioned with respect to each terminal 33. However, as in the above mounting structure, the main body 1 of the electronic component P is not held, and therefore, when used. There is a risk of disconnection due to the vibration generated at.

Further, in the mounting structure shown in FIGS. 23 and 24, each engaging claw 3 provided on the inverted U-shaped fixing part 35.
The main body 1 of the electronic component P is held on the terminal board 32 by inserting and engaging 5a into the engaging holes 32a of the terminal board 32. In this mounting structure, the number of dedicated fixing parts 35 is increased, and the number of man-hours for mounting is also increased, which increases costs. Further, there is a possibility that the fixed component 35 may come off from the terminal board 32 due to vibration during use.

Then, the two leads become horizontal and surely contact with each terminal. Further, also in the second means, when the width of the longitudinal fitting piece formed on the lead side of the main body of the electronic component is made to correspond to the width of the two leads, the two electronic components are mounted in the mounted state. The leads are horizontal and make sure contact with each terminal.
