Abstract

(57) [Summary] [Purpose] The purpose is to provide an inexpensive electronic device with tab terminals that has a high degree of freedom in selecting materials for the base and the like. [Structure] The tab terminals 3 and 4 are made of conductive thin plates, and one end 6 protrudes from the upper surface of a case 13 that covers the base 1. The other ends 7 of the tab terminals 3 and 4 are provided with at least one terminal portion 7 that is substantially symmetrical with respect to the center line, and this terminal portion 7 is made to protrude from the lower surface of the base 1. This allows it to be directly attached to the printed circuit board 14.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to an electronic device with a tab terminal that includes a contact piece portion.

0002

[Conventional technology]

Conventionally, in electronic devices with tab terminals, the positioning accuracy of the tab terminals has been improved, and tab terminals have been In order to accurately set the distance between the contacts provided on the contact piece extending from the For example, there is a method described in Japanese Patent Publication No. 3-657. In this product, a contact terminal plate (a tab with a contact piece part) is installed in a locking groove formed in the body. Terminal), and attach this contact terminal plate to the highly rigid part forming the locking groove to provide elasticity. By pressing down, it can be assembled into the body with precision and held securely. That's what I do.

0003

[Problem that the idea aims to solve]

However, in the above-mentioned model, the contact terminal plate is fixed to the body. Therefore, the body wall thickness has been increased to withstand the load applied when attaching and detaching the contact terminal board. In addition, the body is made of a rigid material such as thermosetting resin. This made it expensive. In view of the above problems, the present invention has a large degree of freedom in selecting materials such as the base, and is inexpensive. The purpose of this invention is to provide an electronic device with a tab terminal that can be used.

0004

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention has a contact plate made of a conductive thin plate and equipped with a contact piece. One end of the tab terminal protrudes from the top surface of the case that is placed over the base, while the tab end The other end of the terminal is approximately symmetrical with respect to the center line of the tab terminal, and at least one terminal The other end of the base is printed with the other end protruding from the bottom surface of the base. It is fixed to the board.

[0005]

[Effect]

According to the present invention, the tab terminal made of a conductive thin plate protrudes approximately symmetrically with respect to the center line. By attaching the terminal section to the printed circuit board, it can be connected directly to this printed circuit board. will be supported and supported.

【Example】

Next, an example of an electronic device with a tab terminal according to the present invention will be explained with reference to the drawings. explain. 1 and 2 show an electromagnetic relay with tab terminals, the base 1 has an electromagnetic Conventionally known internal components such as and contact pieces 5, 10 for fixed contacts and movable contacts. Tab terminals 3 and 4 are attached.

[0007] As shown in FIG. 3, the tab terminal 3 provided with the contact piece portion 5 for the fixed contact The upper end 6 of the tab terminal 3 is a large current socket. On the other hand, a pair of terminal parts 7, 7 protrude from the lower end of the printed circuit board 1. 3 (the terminal portion 7 is electrically connected to the printed circuit board 13). (It may be for connection or simply for fixation). Also, the tab By applying protrusion processing to the lower side of the terminal 3, a pair of retaining protrusions 8, 8 are formed. and can be firmly fixed when press-fitted into the press-fit hole 1a of the base 1. ing. Note that the contact piece portion 6 is provided with a fixed contact 9.

[0008] The tab terminal 4 provided with the contact piece part 10 for the movable contact is a contact piece for the fixed contact. It is almost the same as the tab terminal 3 with the piece 5, but the contact piece 10 is different from the tab terminal 3. The width is narrower than that of the contact piece portion 5 (see FIG. 2). And this contact piece One end of a movable contact piece 11 is fixed to 10, and a free end of this movable contact piece 11 is fixed to A provided movable contact 12 faces the fixed contact 9 so as to be able to come into contact with and separate from it.

[0009] As mentioned above, the electromagnetic relay is assembled into a case after the components are assembled to the base 1. Assemble by covering the coil terminal 2 and tab terminals 3 and 4. is connected to, fixed to, and mounted on the component board 14. In this way, the ends of the tab terminals 3 and 4 Since the child part 7 is fixed to the printed circuit board 14, the upper end part 6 of the tab terminal 3 is Even if the socket is attached or detached, the tab terminals 3 and 4 are not directly protected by the printed circuit board 14. If the contact is held, it may cause wobbling or misalignment, which may affect the distance between the contacts. I've never been there. Therefore, there is no need to make the wall thickness of base 1 large, and the material In addition, the material may be less rigid.

0010

[Effect of the idea]

As is clear from the above explanation, according to the electronic device with tab terminals according to the present invention, , the tab terminal can be directly fixed to the printed circuit board, making it easy to attach to the housing of electronic equipment. , there is no need for a special structure to hold the tab terminal, and the material cost for it is reduced. Manufacturing costs such as processing costs can be reduced, and the degree of freedom in material selection increases.
