Description

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

The terminal board of a slide switch is a board made of synthetic resin with multiple terminals arranged in one or more rows.
A slide switch is configured in combination with a housing housing a sliding member provided with a short circuit.

Conventionally, the terminal board for such a slide switch was
As shown in Figs. 1 to 3, a plurality of terminal fitting holes 2, 2
(The terminal fitting holes 2 are sized and shaped so that the board fitting parts 3b of the terminals 3 are fitted almost tightly.) The wiring connecting part 3a and the board fitting part Terminal 3.3 consisting of 3b and connection point 3C is passed through and fixed, and the periphery is marked with adhesive 4 on the bottom surface of the board 1. This terminal board is made of Insert the terminals 3, 3 into the respective terminal fitting holes 2, 2 of the board 1, fit the board fitting portions 3b into the terminal fitting holes 2, and then remove the board protruding from the bottom of the board 1. The lower edge of the fitting part 3b is caulked as shown in FIG. 2 to fix each terminal 3, 3 to the board 1, and further to airtightly seal each terminal mounting part (for example, to connect the wiring connection part to the circuit board). In order to prevent flux from entering the switch through the terminals during the flux application process performed prior to soldering, the third
As shown in the figure, it is manufactured by applying an adhesive 4 to the lower surface of the board body 1 and marking out the terminal mounting portions.

However, since the conventional terminal board is manufactured by the method described above, it takes time to caulk when fixing the terminals 3, 3, and to apply and dry the beading adhesive 4. There was a drawback that it could not be manufactured efficiently.

This idea was created in view of the above-mentioned circumstances, and its purpose is to make it possible to easily fix the terminal to the board without caulking the terminal as in the past. In addition, it is possible to completely prevent flux from penetrating through the terminal to the contact area on the board without sealing the terminal mounting area, eliminating the need for adhesive markings that were previously required. An object of the present invention is to provide a terminal board for a slide switch that can improve manufacturing efficiency.

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

4 to 8 show the substrate 11, and FIGS. 9 and 1
Figure 0 shows the terminal 13 attached to this board.

The substrate 11 is a thermoplastic synthetic resin plate in which a plurality of terminal fitting holes 12, 12 are arranged in a row, and the terminal fitting holes 12, 12 have the following dimensions and shapes, and the substrate 11 has the following dimensions and shapes. Projections 14, 14 having a width slightly wider than the width of each terminal fitting hole 12, 12 are integrally formed on the lower surface of the terminal 11, that is, the surface of the terminal 13 on the side from which the wiring connection portion 13a protrudes. Each terminal fitting hole 12, 12 is bored in a portion where the protrusions 14, 14 are formed.

On the other hand, the terminal 13 has a shape including a wiring connection part 13a, a wider board fitting part 13b, and a wider contact part 13C.
A claw-like protrusion 13d is formed by cutting and raising the substrate fitting portion 13b of No. 3.

The terminal fitting holes 12, 12 provided in the substrate 11 have a planar shape in which the width at both ends is narrower than the center portion, and the width T1 at the center portion of the terminal fitting holes 12, 12 is as follows. The width is equal to or slightly wider than the thickness t of the terminal 13, and the length Wl of this wide portion is the same as the thickness t of the terminal 13.
The length is the same as or slightly larger than the width W□ of the wiring connection portion 13a of No. 3.

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 10 to 100 mm thick 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 holes 12, 12) is The dimensions are 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 the upper edges of the inner surfaces of both ends of the terminal fitting holes 12, 12 are It is chamfered to provide a guide surface for use.

The width W3 of the protrusion 13d provided on the terminal 13 is approximately the same as the length Wl of the wide portion of the terminal fitting hole 12, and the height of the protrusion 13d and the thickness of the terminal 13 are approximately the same. The additional thickness tl is equal to or slightly larger than the width T1 of the center portion of the terminal fitting hole 12.

The substrate 11 is integrally molded using a resin mold, and the terminals 13 are formed by punching out a single metal plate.

In addition, a board fitting part of 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 attached to the board 11. Moderation plate mounting hole 1 into which 16a and 16a are fitted
5°15 is formed.

The terminal board of this invention is made by press-fitting the terminals 13 and 13 into the respective terminal fitting holes 12, 12 of the board 11 as described above, and this terminal board is manufactured as follows. .

First, from the upper surface side of the board 11, the wiring connection portions 13a, 13 of the terminals 13.13 are inserted into the terminal fitting holes 12, 12, respectively.
a until the lower edge of the board fitting part 13b touches the top surface of the board 11, and insert the terminals 13 and 13 into each terminal fitting hole 12, 12 of the board 11, as shown in FIGS. 12 to 14. hold it.

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 portion 13a can be inserted easily and without difficulty.

However, after the lever, the terminal 13 is pressed by a press-fitting machine (not shown).
Push the board fitting part 13b of the terminal 13 into the terminal fitting hole 12 (push until the contact part 13C of the terminal 13 touches the top surface of the board 11), and then press the board fitting part 1 of the terminal 13 against the board 11.
3b is fitted and fixed.

FIGS. 15 and 16 show a completed terminal board in which the terminals 13 and 13 are fixed to the board 11 in this way, and the moderation plate 16 is fixed to the board 11 with adhesive.

That is, as described above, in this terminal board, the dimensions of the terminal fitting holes 12, 12 provided in the board 11 are set to the width T of the center part.
1 is the length W of the wiring connection portion 13a of the terminal 13 that is greater than or equal to the width W1
1, the thickness of the terminal 13 is greater than or equal to t, and the width T2 at both ends
is smaller than the thickness t of the terminal 13, and the length W between both ends
2 is smaller than the width w2 of the board fitting part 13b of the terminal 13, and the board fitting part 1 is inserted into this terminal fitting hole 12.12.
3b is press-fitted with a terminal 13.13 having a protrusion 13d having a width W3 that is approximately the same as the length Wo of the wide portion of the terminal fitting hole 12. In this terminal board, the terminal 13. Since both side edges of the terminal 13 are press-fitted to both ends of the terminal fitting hole 12 whose width is narrower than the thickness t of the terminal 13, the terminal 13 wobbles into the terminal fitting hole 12 at its both side edges. In addition, the terminal fitting hole 1 is securely fixed in an airtight state without any leakage, and the terminal fitting hole 1 is also fixed in the center part where the protrusion 13d is formed.
2 in a substantially tight fit state, and is furthermore firmly fixed.

In this terminal board, both side edges of the terminal 13 are fitted in both ends of the terminal fitting hole 12 in an airtight state, so that the slack is passed along these parts to the contact part 1 on the board 11.
3C, and even if the wide center part of the terminal fitting hole 12 and the center part of the terminal 13 are not airtightly fitted, the length of the wide part of the terminal fitting hole 12 will not penetrate in this part. Since the flux is blocked by the protrusion 13d, which has approximately the same width as Wl, and the hole on the opposite side thereof (the hole formed by cutting and raising the protrusion 13d), the flux will not penetrate to the top of the substrate 11. .

In the above embodiment, the protrusion 13d is cut and raised on the terminal 12 in order to prevent flux from entering, but instead of forming the protrusion 13d, the terminal 13 has a protrusion 13d at the same position for damming up the flux. It may also be provided with punched holes.

Further, in the above embodiment, the terminal 13 is simply press-fitted into the terminal fitting hole 12 of the board 11, but the terminal 13 is simply press-fitted into the terminal fitting hole 12 of the board 11.
3, if the inner surface of the terminal fitting hole 12 in contact with the terminal 13 is melted while press-fitting the terminal 13 with an ultrasonic welding machine, the inner surface of the terminal fitting hole 12 that is in contact with the terminal 13 can be melted at the same time as the terminal 13 is press-fitted to the board 11. By welding the terminals 13, the mounting strength can be further improved.

Further, in the above embodiment, individual terminals 13.
I am trying to install terminals 13 one by one, but this terminal 13
．． 13 may be installed in the form of a comb-shaped terminal plate and then cut and separated, and furthermore, this terminal plate is not necessarily connected to the moderation plate 1.
6 may not be attached.

Since the terminal board of this invention is as described above, when manufacturing it, the terminals can be easily fixed to the board without caulking the terminals as in the conventional case, and the protrusions or pads formed on the terminals can be used to easily fix the terminals to the board. Since the penetration of the flux into the contact portion can be prevented by the punched holes, there is no need for the marking with adhesive, which was conventionally required, and manufacturing efficiency can be greatly improved.
