Abstract

PURPOSE:To improve the operability on the occasion of wiring and to lessen the kinds of mounted substrates, by dividing necessary spring contact pins into groups by prescribed quantities, and by preparing cassettes in each of which these pins and cables are connected in an integrated structure. CONSTITUTION:Cables 1J-1M are connected to separate spring contact pins 1P-1S so that they constitute cassettes 1A-1D respectively, and the cassettes 1A-1D are fixed in cassette insertion holes 2A-2D of a cassette fixing plate 2 respectively. A performance board 3 is fixed to the cassette fixing plate 2, and LSI 5 mounted on a baby board 4 is pressed and fixed on pins 3A mounted on the board 3. The cassettes 1A-1D are fitted in the insertion holes 2A-2D of the fixing plate 2 after the cables 1J-1M and the pins 1P-1S are fitted therein. Since the fitting of the pins 1P-1S and the connection of the cables 1J-1M thereto are conducted separately for each cassette in this way, the degree of freedom of an operating method is large and, in addition, an operation can be executed for each cassette by a prescribed method.

Description

[Detailed description of the invention] 91.

[Industrial application field]

The present invention relates to an electrical signal connection system, and particularly to a structure suitable for assembly and disassembly.

[Conventional technology]

The conventional device is disclosed in the fourth publication of Japanese Patent Application Laid-open No. 61-201451.
As shown in the conventional example shown in FIG. 5, all of the spring contact pins (contact pins) have an integrated structure.

[Problem that the invention seeks to solve]

In the above conventional technology, all of the spring contact pins (contact pins) are integrated and mounted on one board, so it is difficult to install individual spring contact pins. When attaching a cable to a cable, the spring contact pins and cables that have already been installed may become a hindrance, significantly reducing work efficiency, or the spring contact pins may come into contact with the mating jig or equipment. There were four problems: it was necessary to create a board on which to mount different types of spring contact pins depending on the shape of the device.

The object of the present invention is to improve the workability of mounting the spring contact pin on the board, and to improve the workability of mounting the spring contact pin on the board.
The purpose is to improve workability when wiring cables to pins, and to reduce costs and improve ease of handling by reducing the types of boards on which springs, contacts, and pins are mounted.

[Means for solving problems]

The above purpose is to divide the necessary spring contact pins into a fixed number of units, prepare a cassette with an integrated structure of spring contact pins and cables, and connect this cassette electrically. This can be achieved by arranging and fixing a plurality of pieces in a manner suitable for the structure of the target.

[For production]

The installation of spring contact pins and the connection of cables to them are done separately for each cassette, which gives a high degree of freedom in the work method, and can always be done in the same way for each cassette, improving work efficiency. gets better.

Since the cassettes I- can be arranged in an arrangement suitable for the structure of the counterpart with which the spring contact pins are to be contacted, the types of substrates on which the spring contact pins are mounted can be reduced.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

FIG. 1 shows an exploded view of an embodiment of the invention, with cable I
J~IM is individual spring contact pin IP~
]-8 to constitute cassettes ]-A to ID, respectively, and the cassettes 1-A to ID are fixed to the cassette insertion holes 2A to 2D of the cassette fixing plate 2 with screws 6A to 6H, and the performance The board 3 is fixed to the cassette fixing plate 2 by screws 7A to 7D, and the baby boards 1 to
LSI 5 mounted on 4 is a spring contact pin 3A mounted on performance board 3.
It is pressed and fixed.

The cassettes 1-IA to ID are attached to the cassette insertion holes 2A to 2D of the cassette fixing plate 3 after three months after the cables IJ-M, spring contacts 1 to 1, and pins IP to IS are attached.

FIG. 2 shows an exploded view of the cassettes IA-ID shown in FIG. and the board mounting lid 10 by screws 13A to 13D.

FIG. 3 shows a plan view of the exploded view shown in FIG. 2 after assembly;
The configuration is similar to that described in FIG.

FIG. 4 is a sectional view showing how to connect the spring contacts 1 to pins 11 and 14 shown in FIG. 2 and the cable 12 connected thereto.
The line 12A is connected to the inner layer GND 16 through the through hole 12C.
and outer layer GND17A.

17 by solder 19, and the signal line 12B of cable 12 is connected to spring contact pin 11 by solder 18.
The spring contact pin 11 is made up of a spring IIB and a contact pin 1A pushed in a certain direction by the spring 11B.
The pin 11 is connected and fixed to the signal pattern 15 on the printed circuit board 9, and the spring contact pin 14A is connected to GND.
It is connected and fixed to the pattern 17. Spring contacts 1 to pin 11 and signal pattern 15 are connected to inner layer GND 16 and outer layer GND 17A.

It is designed to have a constant characteristic impedance with respect to 17.

According to this embodiment, since the spring contact pins can be mounted and the cables connected in advance for each cassette, the assembly work is easy and the spring contact pins and cables can be easily repaired. It becomes easier.

〔Effect of the invention〕

According to the present invention, (1) Mounting of the spring contact I-pin and connection of the cable are done in a cassette!・Workability is improved because it can be removed in units.

(2) Arrange the cassettes in an arrangement suitable for the mating structure that the spring contact pins are to contact.

Since the pin can be inserted into the spring contact 1, the number of types of boards to which the pin is fixed can be reduced.
