Description

[Detailed description of the invention] This invention relates to a terminal mounting board for a slide switch.

The terminal board of a slide switch is a terminal mounting board made of synthetic resin with a plurality of terminals arranged in one or more rows, and is combined with a housing housing a sliding member equipped with a short circuit so that the terminal board can slide. It constitutes a switch.

Conventionally, as a terminal mounting board for such a terminal board for a slide switch, there is one in which a plurality of terminal fitting holes 2, 2 are arranged in a row in a board body 1 made of synthetic resin as shown in FIG. The terminal fitting holes 2, 2 are dimensioned and shaped so that the board fitting part 3b of the terminal 3, which is made up of a wiring connection part 3a, a board fitting part 3b, and a contact part 3C, is fitted almost tightly.

This terminal mounting board is manufactured by inserting the terminals 3, 3 into the terminal fitting holes 2, 2 and fitting the board fitting parts 3b into the terminal fitting holes 2, as shown in FIG. The lower edge of the board fitting part 3b protruding from the bottom of the main body 1 is caulked as shown in FIG. 2 to fix each terminal 3, 3 to the board main body 1, and further seal each terminal mounting part airtightly. (For example, to prevent flux from entering the switch from the terminal attachment part during the flux application process that is performed before soldering the wiring connection part to the circuit board.) The terminal board is made by applying an adhesive 4 to the lower surface of the terminal board 1 and cutting out the terminal mounting portion.

However, since the above-mentioned conventional terminal mounting board is used as a terminal board by attaching the terminals 3, 3 in the above-described manner, it is difficult to secure the terminals 3, 3 when fixing them, or as a blind. There was a drawback that it took time to apply and dry the adhesive 4, making it impossible to efficiently manufacture the terminal board.

This idea was created in view of the above-mentioned circumstances, and its purpose is to make it possible to weld and fix the terminals to the board, without having to caulk the terminals as in the past. The manufacturing efficiency of the terminal board has been improved by making it easy to fix, and by welding and fixing the terminal, the terminal mounting part is airtightly sealed, eliminating the need for marking with adhesive, which was previously required. It is an object of the present invention to provide a terminal mounting board for a slide switch which can be improved.

An embodiment of this invention will be described below with reference to the drawings.

4 to 8 show the terminal mounting board of this invention, and FIGS. 9 and 10 show the terminals mounted on this terminal mounting board.

This terminal mounting board has a plurality of terminal fitting holes 12, 12 arranged in a row in a board body 11 made of thermoplastic synthetic resin.
2 and 12 have the following dimensions and shapes, and on the lower surface of the board main body 1, that is, on the side from which the wiring connection portion 13a of the terminal 13 protrudes, there are holes along both side edges of each of the terminal fitting holes 12, 12. A pair of protrusions 14.14 are formed.

On the other hand, the terminal 13 is similar to that provided on a conventional terminal board, and includes a wiring connection part 13a, a wider board fitting part 13b, and a wider contact part 13C. This terminal 1
3 has the same thickness throughout.

The terminal fitting hole 12° 12 provided in the board body 11 has a planar shape that is symmetrical at both ends and both sides, with the width of both ends narrower than the center part. The width T1 at the center of the terminal 13 is equal to or slightly wider than the thickness t of the terminal 13,
The length Wl of this wide portion is the wiring connection portion 1 of the terminal 13 =
The length is equal to or slightly larger than the width Wl of a.

Moreover, the width T2 of both ends of the terminal fitting holes 12, 12 is as follows:
The width W2 is smaller than the thickness t of the terminal 13 (approximately 1,000 to 1,000 mm of the terminal thickness), and the total length (including the long and narrow portion between the inner surfaces of both ends of the terminal fitting hole 12.12) is , is smaller than the width W2 of the board fitting portion 13b of the terminal 13 (larger than the width W1 of the wiring connection portion), and furthermore, the upper edges of the inner surfaces of both ends of the terminal fitting holes 12, 12, into which the terminal 13 is inserted It is chamfered to provide a guide surface for use.

On the other hand, protrusions 14.14 protrudingly formed on the lower surface of the board body 11 along both side edges of the terminal fitting holes 12, 12 are formed over the entire length of the terminal fitting holes 12. The inner surfaces of the protrusions 14, 14 are flush with the inner surfaces on both sides of the terminal fitting hole 12, and the inner surfaces of both ends of the protrusions 14, 14 are flush with the inner surfaces of both sides of the terminal fitting hole 12. It extends to the inner surface of the narrow width portion of the terminal fitting hole 12 so as to be flush with each other.

Note that this terminal mounting board is integrally molded using a resin mold.

In addition, a moderation plate 16 made of synthetic resin (for contacting the sliding member of the slide switch to give a sense of moderation to the switch switching operation) as shown in FIG. 11 is fitted onto the board body 11. A moderation plate mounting hole 15.15 is formed into which the portions 16a, 16a are fitted.

Next, a method of manufacturing a slide switch terminal plate by attaching the terminals 13 and 13 to this terminal attachment board will be described.

First, from the top side of the board body 11, each terminal fitting hole 12.12
Wiring connections 13a of terminals 13 and 13, respectively.

13a until the lower edge of the board fitting part 13b touches the top surface of the board, and as shown in FIGS.
Terminals 13 and 13 are held in the respective terminal fitting holes 12 and 12, respectively.

In this case, the terminal fitting hole 12 has a width dimension that is equal to or slightly greater than the thickness t of the terminal 13 over a length that is equal to or slightly greater than the width W1 of the wiring connection portion 13a at the center portion. Therefore, the wiring connection part 13a can be inserted easily and without difficulty, and the inserted terminal 13 is also supported between the protruding pieces 14 and stably held in an upright state. .

However, after levering, the terminal mounting board holding the terminals 13 and 13 is supported on a support base (not shown) having a receiving part for receiving the outer surfaces of the protrusions 14, 14 from the outside. The board fitting portion 1 of the terminal 13 is bonded by a sonic welder (not shown).
3b into the terminal fitting hole 12, the inner surface of the terminal fitting hole 12 and the inner surface of the protrusions 14, 14 which are in contact with the terminal 13 are melted, and the board fitting portion 13b of the terminal 13 is connected to the contact portion 13C.
At the same time, the board fitting portion 13b of the terminal 13 is welded to the board.

The terminal 13 welded to the substrate in this way has both side edges narrowed in width than the narrow part of the terminal fitting hole 12, that is, the thickness t of the terminal 13, and the end face is melted in the portion located inside the terminal side edge. The entire vicinity of the terminal is welded in an airtight state, and both surfaces of the terminal are welded in an airtight state throughout by melting the large pieces 14, 14 over the entire length of the terminal fitting hole 12. The protruding portion is melted and swept outward along the terminal surface, thereby fixing the terminal to the substrate in a state where the airtightness of both side edges of the terminal is further improved.

FIGS. 15 and 16 show a completed terminal board in which the terminals 13 and 13 are fixed to the terminal mounting board in this manner, and the moderation plate 16 is adhesively fixed to the board.

Incidentally, although the extending portions at both ends of the protruding pieces 14, 14 are not necessarily required, the protruding height of the protruding pieces 14, 14 is larger than that of the board main body 1.
It is desirable that the protrusion length be approximately the same as the protrusion length of the substrate fitting portion 13b protruding from the lower surface of the substrate 1.

That is, according to this terminal mounting board, the terminal fitting hole 12
, 12 have the above-mentioned shape and dimensions, and protrusions 14, 14 are provided on the bottom surface along both sides of the terminal fitting hole 12 over the entire length of the terminal fitting type, thereby ensuring airtightness of the terminal over the entire circumference. It is possible to secure and firmly weld and fix the terminals, and therefore, there is no need to caulk the terminals or mark them with adhesive as in the past when manufacturing terminal boards, simplifying the process. Can be done.

In the above embodiment, each terminal 13. is provided on the terminal mounting board.
I am trying to install terminals 13 one by one, but this terminal 13
．． 13 may be attached in the form of a comb-shaped terminal plate and then cut and separated, or the first
As shown in FIGS. 7 and 18, a notch 17 or a large number of diagonals 18 may be provided in the board fitting portion 13b of the terminal 13.

Moreover, the moderation plate 16 does not necessarily need to be attached to this terminal mounting board.

Since the terminal mounting board of this invention is as described above, the terminals can be reliably welded and fixed to the board when manufacturing the terminal board, and therefore the terminals can be fixed to the board without caulking as in the conventional method. In addition to being easy to fix, the terminal mounting area can be airtightly sealed by welding and fixing the terminals, which eliminates the need for marking with adhesive, which was previously required, and greatly improves the manufacturing efficiency of terminal boards. −
