Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a socket for mounting components used in electronic equipment such as computers, television receivers, and video cassette recorders.

Conventional technology Conventionally, when measuring the characteristics of a component mounted on a board via a mounted component socket, an electrical signal is extracted from the surface where the socket is mounted and the connection terminal is soldered (hereinafter simply referred to as the terminal surface). Generally, this is done by holding the socket's connecting terminal with a clip, or by soldering a lead wire to the socket's connecting terminal or the electrode land on the terminal surface of the printed circuit board that is connected to the socket's connecting terminal. there were.

FIG. 3 shows the structure of a conventional socket. Reference numeral 1 denotes a resin body constituting the socket, and a large number of connection terminals 2 are implanted therein. Figure 4 shows the same socket mounted on a board and an IC
3 is a sectional view of the main parts showing the state when parts such as the above are mounted, 3 is a board on which an electrode land 4 is provided, 5 is a mounted part such as an IC equipped with a terminal 6, 7 is solder, 8 is the lead wire.

Next, its operation will be explained. In the above configuration, I
When measuring the characteristics of a component 5 such as C, a socket is first mounted on the board 3 and the connecting terminal 2 is attached to the electrode land 4 with solder 7. Next, the component 5 is mounted by inserting its terminal 6 into the upper part of the connection terminal 2 of the socket, and the lead wire 8 is soldered to the tip of the connection terminal 2 or the electrode land 4, and the electrical signal of the component 5 is extracted. It can be measured by

Problems to be Solved by the Invention However, in the conventional configuration described above, when extracting an electrical signal, all measurable terminals 6 of the component 5 do not necessarily appear on the terminal surface, and in order to extract an electrical signal, There is a complication in that the tip of the connecting terminal 2 has to be held with a clip (not shown) or a large number of lead wires 8 have to be soldered. In particular, when a large number of connection terminals 2 are held by clips, there is a problem that they may come off during measurement.

The present invention solves the above-mentioned conventional problems, and is an excellent socket for mounted components that can extremely easily take out electrical signals without requiring clips or soldering of lead wires 8 to take out electrical signals. The purpose is to provide the following.

Means for Solving the Problems In order to achieve the above object, the present invention has two or more fitting pins and a plurality of terminals on the lower surface, and an insertion hole for a mounted component that communicates with the plurality of terminals on the upper surface. a fitting recess at a position on the upper surface corresponding to the fitting pin, a plurality of electrode terminals that contact each of the plurality of terminals, and a signal cable connected to each of the electrode terminals. It consists of a signal extraction section.

Therefore, according to the present invention, when a socket for a mounted component is constituted of a component mounting part and a signal extraction part, and the characteristics of a component are measured via the component mounting part mounted on a board, the signal extraction part is connected to the component mounting part. By fitting the terminals into the parts, all the terminals of the parts are electrically connected to the signal cable at the same time, making it extremely easy to take out electrical signals.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the configuration of an embodiment of the present invention.

In the figure, reference numeral 10 denotes a component mounting part, and fitting pins 11 are implanted in the four corners of the lower surface, and terminals for components such as ICs, which will be described later, are formed on the upper surface of the two long sides. A large number of terminals 12 are provided to which terminals of the component are connected when the component is mounted through the insertion hole 12a.

Reference numeral 13 designates a signal take-out portion having a signal cable 14 as a part thereof, and a fitting recess 15 into which a fitting pin 11 is inserted on the upper surface thereof, and an electrode terminal 1 corresponding to the terminal 12, respectively.
6 is provided.

Next, the operation of the above configuration will be explained using FIG. 2. FIG. 2 shows the main parts of an embodiment of the present invention in which a socket is mounted on a board and components such as an IC are attached, where 17 is a board with insertion holes 18 for terminals 12, and 19 is a board in which insertion holes 18 for terminals 12 are drilled. It is a component such as an IC that has a large number of terminals 20 on its side.

First, the component mounting section 10 is inserted into the insertion hole 1 provided in the board 17.
A fitting pin 11 and a terminal 12 are inserted into each of the parts 8 and fixed with solder 21, and a component 19 such as an IC is mounted on this component mounting portion 10 to constitute a circuit board and is grounded. Next, when measuring the characteristics of this component 19, the electric signal extraction section 13 is fitted into the component mounting section 10 via the substrate 17 by coupling its fitting recess 15 with the fitting pin 11 of the component mounting section 10. Let them wear it. At this time, each terminal 12 has a corresponding electrode terminal 16
It comes into contact with and makes an electrical connection.

Therefore, the electrical signal occurring at the terminal 20 of the component 19 is transmitted through the terminal 12 to the electrode terminal 16, and furthermore, the signal cable 1 connected to the electrode terminal 16, respectively.
4 to an external measuring device (not shown), where various characteristics can be measured.

Note that the electrode terminals 16 are each supported by springs 22, and electrical continuity with the terminals 12 is maintained in a stable state.

As described above, according to the above embodiment, since the socket is composed of the component mounting section 10 and the signal extraction section 13, when measuring the characteristics of the component 19, the signal extraction section 13 is fitted into the component mounting section 10. Simply connect the signal cable 14
It is possible to extract electrical signals from the wire, and there is no need to use lead wires, which are unstable to install and require work to attach or solder (it is possible to easily measure the characteristics). It is.

Effects of the Invention As is clear from the above embodiments, the present invention provides a socket for mounted components that includes a component mounting section for mounting components on a board to configure an electronic circuit and a signal extraction section used for measuring the characteristics of the component. This configuration eliminates the need for soldering when extracting electrical signals, thereby preventing product deterioration and improving reliability, which is greatly useful for improving work efficiency.
