2. Description of the Related Art Conventionally, in order to miniaturize electronic devices and increase the mounting density of printed wiring boards, capacitors, resistors,
Switching of conventional components such as transistors from those with lead wires to those without lead wires, so-called electronic component chips are being promoted. Such chip parts are
It has a terminal portion whose both ends are plated with Ag or Ag-Pd, and is mounted on a printed wiring board by directly soldering these terminal portions onto a flat chip land. However, due to the circuit configuration, it is sometimes necessary to mount a chip component on a printed wiring board having only through holes having no chip land. In such a case, conventionally, a blind via hole having a copper-plated lid is formed on the through hole,
The chip parts were mounted on the through holes by directly soldering the terminal parts of the chip parts onto the copper plating.

[0003]

At the stage of trial production of a printed wiring board, after confirming the electrical characteristics of the circuit,
It may be necessary to replace the chip component. However, in the above-described conventional method for mounting a chip component using the blind via hole, the terminal portion of the chip component is directly soldered onto the mounting land, so that the soldering iron is locally localized when the chip component is replaced. There is a problem that the circuit pattern (copper-plated lid) on the printed wiring board and the terminal portion of the chip component are damaged by heat.

The present invention has been made in view of the above problems, and it is possible to mount a chip component in a through hole and to easily replace the chip component without damaging the circuit pattern and the chip component. The purpose is to provide a socket for parts.

[0005]

In order to achieve the above object, a socket for chip parts of the present invention is a socket for mounting a chip part in a through hole on a printed wiring board. A socket portion including a fixed plate to be placed and gripping plates that are located on both side edges of the fixed plate and that grip the terminal portion of the chip component and electrically connect the chip component, and hang down from the socket portion. And a lead portion to be soldered to the through hole.

[0006]

According to the chip part socket of the present invention having the above-mentioned structure, the lead parts of the pair of two chip part sockets corresponding to both terminal parts of the chip part are soldered to the through holes, The chip parts are detachably mounted on the printed wiring board (through holes) by press-fitting the terminal parts of the chip parts into the socket parts of the chip part socket.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a chip component socket of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a chip component socket according to this embodiment.

In the figure, reference numerals 11 and 12 denote two pairs of sockets for chip parts, which are a socket portion 20 formed by bending a conductive metal plate member into a substantially U shape, and this socket. It is composed of two lead portions 30 and 30 that are provided so as to hang down from the portion 20. Socket part 20
Is the fixing plate 21 on which the terminal portion 41 of the chip component 40 is placed.
And the terminal portions 4 are erected on both side edges of the fixing plate 21.
It is composed of a grip plate 22 for gripping 1. This grip plate 2
2, the chip component 40 can be attached and detached, and the chip component 40 has elasticity to such an extent that the chip component cannot be easily detached while gripping the chip component. In addition, a protrusion 22 a that serves as a contact point with the terminal portion 41 is formed in the lateral direction at the center of the grip plate 22. Further, the socket portion 20 on the side of the one chip component socket 11 is provided with a shoulder plate 22b for preventing displacement of the chip component 40 in the longitudinal direction and for positioning. The two lead portions 30 and 30 described above are integrally provided so as to hang down from the fixing plate 21 of the socket portion 20 as described above. The distance between the lead portions 30 and 30 is a through hole on the printed wiring board. It corresponds to the interval of 50, 50.

Next, the operation of the chip component socket of the present embodiment having the above structure will be described with reference to FIG. First, the lead portions 30, 30 are connected to the through holes 50,
The chip component sockets 11 and 12 are fixed to the printed wiring board by soldering to the chip 50. Next, the socket part 2
When the terminal parts 41, 41 of the chip part 40 are press-fitted between the grip plates 22, 22, 22, 22 of 0, 20 and the chip part 40 is positioned by the shoulder plate 22b, the terminal parts 41, 4 are formed.
1 is gripped via the protrusions 22a, 22a, 22a, 22a. As a result, the chip component 40 is mounted in a state of being electrically connected to the circuit on the printed wiring board. Further, the chip component 40 mounted by the sockets 11 and 12 for the present chip component can be easily removed from the socket portions 20 and 20 by pulling upward.

According to the chip component socket of this embodiment, the chip component 40 can be mounted on the through holes 50, 50, and the circuit pattern and the chip component 40 can be formed on the printed wiring board having the through holes. The chip parts can be easily replaced without damage.

The chip component socket of the present invention is
The invention is not limited to the above embodiment. For example, the shapes of the sockets 20 and 20 are not limited to those shown in the drawings, and other shapes can be used as long as the terminals 41 and 41 of the chip component 40 can be firmly gripped and the chip component 40 can be easily attached and detached. You may change it. In addition, in the above-described embodiment, each of the chip component sockets 11 and 12 has two lead portions 3.
Although 0 and 30 are formed, the mounting area of the chip component 40 can be reduced by using one lead portion each.

[0012]

As described above, according to the chip component socket of the present invention, the chip component can be mounted on the through hole, and the chip component can be easily mounted without damaging the circuit pattern and the chip component. Can be exchanged.
