Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an adjustment component socket for surface mounting adjustment components on a printed circuit board.

<Prior art> A conventional method for mounting adjustment components is, for example, as shown in FIG. 3, a pair of terminals 2 dedicated to adjustment components are inserted into a printed circuit board 1, and an adjustment component 3 is sandwiched between these terminals 2. was.

<Problems to be solved by the invention> In recent years, with the miniaturization and weight reduction of electrical products, circuit mounting has become more dense and surface mounting has become mainstream.

However, as for adjustment parts, the conventional mounting method using the terminal 2 and the like as described above is used, which is a factor that hinders high-density circuit mounting. Further, regarding the mounting process, there was a problem in that since the mounting form of the adjustment component and the surface mounting component were different, they could not be mounted in the same process, making the mounting process complicated.

This idea was made in view of the above-mentioned circumstances.
An object of the present invention is to provide an adjustment component socket that enables surface mounting of adjustment components.

<Means for Solving the Problems> For this reason, the present invention includes a resin-made socket body formed in a substantially concave shape, vertically penetrating through and fixed to the opposing end surfaces of the socket body, and facing each other; The upper part is formed into a bifurcated shape and has a pair of terminal pieces having spring properties that contact each end face of each adjusting part to be stored in parallel and elastically clamp the part, and the lower part of the pair of terminal pieces is connected to the lower part of the socket main body. The adjustment component socket has a structure in which the protruding portion is bent at a substantially right angle along the bottom surface of the socket body on the outer side of the end face portion of the socket body.

<Function> In the above configuration, the socket can be fixed to the printed circuit board by placing the socket on the printed circuit board and soldering to the circuit board via the bent protrusion of the terminal piece. The adjustment component can be surface-mounted by simply fitting the adjustment component between the terminal pieces of the socket, making it possible to further increase the density of circuit mounting and simplifying the circuit component mounting process. Furthermore, by bending the lower part of the terminal piece so that it protrudes from the bottom of the socket body, it is possible to create a gap between the bottom of the socket body and the board when the socket is installed on a printed circuit board, which makes it easier to secure the socket with solder. A space is created to release the generated gas. Further, since the adjustment parts can be arranged in parallel, adjustment parts for coarse adjustment and fine adjustment can be provided, making adjustment easy.

<Example> An example of the present invention will be described below based on FIGS. 1 and 2.

In the adjustment component socket 10 of the present embodiment shown in the figure, a resin socket main body 11 formed in a substantially concave shape on the bottom plane has end face portions 11 facing each other.
Flat and rectangular terminal piece insertion hole 11 in a, 11a
b, 11b are formed to penetrate in the vertical direction. A partition wall 11d is provided in the space between the end surfaces 11a, 11a of the socket body 11 to separate the adjustment components 13 stored in parallel. A pair of terminal pieces 12, 12 having spring properties that elastically sandwich the leadless adjustment component 13 pass through the respective terminal piece insertion holes 11b, 11b in the vertical direction and are fixed facing each other. Each of these terminal pieces 12 has a bifurcated upper part and has a contact part 12a that contacts the adjustment component 13, and a stepped locking part formed in the terminal piece insertion hole 11b between the contact parts 12a. Part 11
It has a shape that includes a tongue piece 12b that comes into contact with c from below and prevents the terminal piece 12 from coming off upward. and,
A protruding portion 12c of each terminal piece 12 that protrudes downward from the socket body 11 is bent at a substantially right angle along the bottom surface of the socket body 11 on the outer side of the end face portion 11a. 14 is a printed circuit board, and 15 is solder.

When mounting an adjustment component using such a socket 10, first, the socket 10 is attached to the protrusion 1 of the terminal piece 12 in the same mounting process as other surface mount components.
It is soldered and fixed onto the printed circuit board 14 via 2c. When the leadless adjustment component 13 is fitted between the pair of terminal pieces 12 of the fixed socket 10, the contact portions 12a of the terminal pieces 12 elastically clamp the adjustment component 13.

According to the adjustment component socket 10 having such a configuration,
There is no need to insert it into the printed circuit board 14, and it can be attached to the printed circuit board 14 in the same process as other surface mount components, simplifying the mounting process. In addition, surface mounting of the adjustment component 13 becomes possible, and the circuit mounting density can be further increased. Furthermore, in the conventional terminal 2, a certain length of the terminal 2 was required in order to give the terminal 2 sufficient springiness, but with this socket structure, the terminal piece 12
Even if it is shorter than the conventional terminal 2, it can have sufficient springiness, so the printed circuit board 14
The height can be lowered. Therefore, in combination with surface mounting, the product can be further miniaturized.
Furthermore, when soldering and fixing to the printed circuit board 14, there is a gap between the bottom surface of the socket body 10 and the circuit board 14, so that gas generated during soldering can escape easily. In addition, since two adjustment parts are provided horizontally in parallel, adjustment work can be facilitated by using one for coarse adjustment and one for fine adjustment, respectively.

<Effects of the invention> As described above, according to the invention, it is possible to surface-mount the adjustment parts, and the mounting height of the adjustment parts can be lowered, so the circuit mounting density can be increased and the product can be improved. It can be made even more compact. Also,
Since it can be attached to a printed circuit board in the same process as other surface-mount components, the mounting process can be simplified and costs can be reduced. Furthermore, since there is a gap between the printed circuit board and the bottom of the socket, gas can be vented well during soldering. In addition, since the adjustment parts are arranged horizontally in parallel, adjustment work is made easier by having adjustment parts for coarse adjustment and fine adjustment, and since they are arranged horizontally in parallel, the adjustment parts can be easily replaced. be.
