Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a wiring member for a switch body used in a switch having electrical connection terminals such as a switch, and a method for assembling the switch body.

(Background Art) Generally, as shown in FIG. 6, a switch such as a switch is built into a printed circuit board 3 together with a group of other circuit components (not shown) such as a TC and a capacitor, and constitutes a circuit that performs a predetermined operation. be done.

Conventionally, the electrical connection between this type of switch 2 and the printed circuit board 3 has been carried out using a hole 3 in the printed circuit board 3 on which a conductive part 3b having a predetermined circuit pattern has been formed in advance by etching or the like on the back surface.
The terminal 2a of the switch 2 was inserted through the terminal 2a, and the terminal 2a and the conductive part 3b were connected by soldering or the like on the back side of the printed circuit board. Further, a lead wire 5 connected to other circuit components etc. may be connected to the conductive part 3b functioning as a lead wire of the switch 2, and/or a lead wire 5 connected directly to a predetermined terminal 2a may be connected.
A switch was mounted on a printed circuit board by connecting lead wires 5 to the terminals with soldering wires 4 to form a predetermined circuit.

In this case, when electrically connecting the switch 2 such as a switch to the printed circuit board 3, there were many problems in mounting. In particular, the work of soldering the lead wire 5 to the terminal 2a, the increase in the area used for the conductive part of the printed circuit board, the electrical insulation treatment for strong and weak electric currents, and the connection treatment when the number of terminals increases are serious problems. It had become.

Further, for example, when it becomes necessary to make various design changes to the circuit or when mounting a different type of switch 2, pattern wiring of the desired conductive part is formed on a new printed circuit board 3 by etching or the like each time. The disadvantage is that it is necessary and very complicated.

(Objective of the Invention) The present invention has been proposed in view of the above points, and its purpose is to provide a simple structure with high packaging density, safety, etc., and to easily adapt it to any design. It is an object of the present invention to provide a wiring member for a switch body of a switch such as a switch and a method for assembling the switch body.

(Disclosure of invention) Hereinafter, the present invention will be explained along with the drawings.

FIG. 1 shows an embodiment of a wiring member for a switch body according to the present invention, and this wiring member 1 for a switch body is made of a conductive material such as a conductive full tick, a copper plate or a brass metal plate, or a conductive film. The conductive portion 1a is arranged in a lattice pattern and can be separated at appropriate points, and a rod-shaped outer periphery holding portion 1b connecting the conductive portions 1a and the periphery of the conductive portions 1a are connected. Note that a switch 2 such as a switch, which will be described later, is installed at an appropriate position of the grid conductive portion 1a.
A plurality of terminal insertion holes 1C are bored through which the terminals 2a of the switch body are inserted and the switch body 2 and the wiring member 1 are integrated, and this switch body wiring member 1 functions as a so-called wiring fitting. be.

When using or assembling the switch body, as shown in Figure 2, the wiring member 1 made of a grid-like metal plate, etc., is all of the same polarity as it is, so leave the necessary electric wiring circuit pattern part and connect the other parts. The unnecessary portions of the conductive portion 1a and the outer periphery holding portion 1b are cut and separated as shown by broken lines and removed. However, the outer periphery holding portion 1 around the conductive portion 1a that is required
b is left as is for ease of assembly, and is removed after mechanically and electrically connecting it to the terminal 2a of the switch 2 through the terminal insertion hole 1C, as shown in FIG. By cutting unnecessary parts of the lattice-shaped conductive parts 1a, each becomes an independent conductive part 1a, and if necessary, the outer ends of the grid-like conductive parts 1a can be bent downward and used as pull-out terminals that can be pulled out to the outer periphery of the switch. I growled.

Next, as shown in FIGS. 4 and 5, after installing the switch body wiring member 1 into the terminal part of the switch 2, the hole 3 is
The switch body can be assembled by inserting the terminal 2a of the switch 2 itself and a lead-out terminal consisting of a conductive part into the switch a and mounting the switch 2 on the upper surface of the printed circuit board 3.

Then, on the back side of the printed circuit board 3, the conductive parts I to 1 which function as lead-out terminals of the switch 2 are connected to the printed circuit board 3.
It is connected to a conductive part such as copper foil provided on the back side.
Preferably, soldering 4 may be performed as appropriate to ensure the connection. However.

The electrical wiring between this switch 2 and other parts can be connected to the lead-out terminal of the switch body wiring member 1 made of this metal plate, etc., so that the terminal 2a of the switch body does not need to be directly used. The pattern wiring and lead wire wiring on the printed circuit board 3 under the switch main body are significantly l! Can be converted into J element.

(Effects of the Invention) As described above, according to the present invention, unnecessary conductive parts of a wiring member for a switch body made of a conductive metal plate or a conductive film having conductive parts arranged in a lattice pattern and capable of being separated are eliminated. A switch body is assembled by dividing and removing the part, and incorporating it into a switch as a lead-out terminal for a switch such as a switch that is suitable for connection to a printed circuit board, and connecting the lead-out terminal to the conductive part of the printed circuit board. It was made into
In this case, since the wiring member for the switch assembly that functions as a lead-out terminal is provided on the top surface of the printed circuit board, the conductive part on the back surface of the printed circuit board can be effectively used, and by changing the thickness, width, etc. of the wiring member, It has the advantage of being compatible with both low-power and low-power sources.

Furthermore, since the lead-out terminal can be taken out at the outer periphery of the switch, there is an advantage that routing of the back surface of the printed circuit board under the switch mounted on the printed circuit board is simplified.

Furthermore, since the electrical wiring between the switch and other parts is connected to the pull-out terminal of the switch body wiring member, there is no need to directly use the terminal on the switch body, so the switch #1. The pattern wiring and lead wire wiring on the back side of the printed circuit board under the IF body can be greatly simplified.

In addition, if the wiring member for the switch body is divided according to the type of switch and the circuit, it is possible to easily obtain the desired pull-out terminal for the switch, which has the advantage of being highly versatile and easily adaptable to design changes. .
