Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic circuit package connection device that prevents components mounted on the electronic circuit package from being destroyed by an electrostatic cage.

In conventional electronic circuit packages, when the electronic circuit package is pulled out of the connector, all of the contacts on the electronic circuit pancase are open. Therefore, when handling the electronic circuit package, a static electricity surge may enter from the plug and destroy electronic components such as the Qt and integrated circuit mounted on the electronic circuit package.

In other words, static electricity accumulates in the human body due to friction from clothing, etc., and when the air is dry, if a 1H or the like touches an open connector on an electronic circuit package, the accumulated electricity connected to that connector will be damaged. Static electricity discharges through the terminals of one path, causing an excessive current to flow, which may destroy the inside of the integrated circuit.

As described above, the conventional electronic circuit pancase and connector assembly did not have any protection measures against static electricity.

The present invention has been made in view of the above, and its purpose is to short-circuit all the connector plugs when an electronic circuit package is removed from the connector, and to prevent the static electricity cage from entering. At the same time, when inserted into the connector, the short circuit of the plug is released and a pressure-tight connector connection is established.
It is an object of the present invention to provide a connection device for an electronic circuit package that can be used for connecting electronic circuit packages.

Hereinafter, embodiments of the present invention will be described. FIGS. 1 to 3 show one embodiment of the present invention, in which numeral 1 represents an electronic circuit pancase and 2 represents a connector. Although not shown, predetermined electronic components are mounted on the electronic circuit pancase l, and are covered with a shielding case if necessary. A plurality of plugs 4 are formed by printing on the front side of the insertion portion 3a of the board 3 into the connector 1, and a plurality of plugs 5 are similarly formed on the back side. Note that printed wiring is provided from this plug 4.5 toward the inside of the electronic circuit package 1.

- A plurality of elastic contacts 7a of the upper lead pin 7 and elastic contacts 8a of the upper lead pin 8 are bent into the inside 6a of the housing 6 of the connector 2 so as to face each other. It is formed by

and the insertion portion 3a of the electronic circuit package 1.
A short-circuiting plate 11, I2 having a wavy side surface is attached at a position away from the insertion tip with a screw 13 via an insulator 9.10. In addition, this screw 13
is inserted in a position where it does not contact the plug 4.5. The shorting plates 11.12 are elastically in contact with the plugs 4.5, and their tips 11a, 12a are connected between the plugs 4.5 and ^1.
I'm facing the direction of 1°ζ. In addition, the shorting plate 11 has a connecting plug 4.
A recessed notch llb is formed to ensure contact with the short circuit plate 12, and a similar notch (marked by box M in the figure) is also formed in the shorting plate 12. - No.j, the upper and lower sides of the opening 6b in the housing 6 of the connector 2 into which the insertion portion 3a of the board 3 is inserted are formed as protrusions 6C16d with sharp tips.

In the above, when the electronic circuit package 1 is pulled out from the connector 2, as shown in FIGS.
12 are in elastic contact with all of the connectors 5 on the back side, and all of the connectors 4.5 are short-circuited to each other. Therefore, static electricity surges can be transmitted from the connector 4.5 to the electronic circuit pancake 1.
There is no way to get inside.

On the other hand, when the electronic circuit package 1 is inserted into the connector 2, the tip 1 of the shorting plate 1112 of the electronic circuit package 1
1a and 12a ride on the protrusions 6c and 6d of the housing 6, and as a result, the short circuit plate 11.12 separates from the plug 4.5, and the short circuit is released, and the plug 4.5 is moved to the lead pin 7. 8 contacts 7a and 8a. Therefore, when inserted into the connector 2, the connection state is completely fixed.

As described above, according to the present invention, the electronic circuit package is provided with the shorting means that contacts the plurality of connectors in common, and by inserting the electronic circuit package into the connector, the shorting means is connected to the F411 from the connector. , and when the electronic circuit package is pulled out from the connector, the short-circuiting means short-circuits the plug, and therefore, while the electronic circuit package is being pulled out from the connector, the short-circuiting means short-circuits the plug at that time. No static electricity surges can enter from the plug. Therefore, electronic components such as integrated circuits mounted on the electronic circuit 1/3 package can be protected from destruction due to the N'f1''i1i air surge.
