Description

[Detailed description of the invention] [Field of industrial application] This invention is a method for mounting and connecting a plate-like circuit body such as a package containing circuit elements such as ICs and LSIs and their connecting conductors to other printed circuit boards, etc. Concerning connectors for

[Conventional technology]

Some packages, such as ICs and LSIs, have a connection conductor at the end, for example, a connection contact instead of a connection lead wire. When mounting and connecting such a package to another printed circuit board or the like, a connector as shown in FIGS. 9 to 11, for example, is used. The connector includes a large number of electrically conductive and elastic contacts 1, a socket body 2 incorporating these contacts 1, a holding plate 3 pivotally attached to one end of the body 2, and the other end of the socket body 2. The hook member 4 is pivotally connected to the hook member 4. The socket body 2 is made of electrically insulating material.

At the time of connection, a package 7 is placed on top of the contact 1. The package 7 includes circuit elements such as ICs and LSIs and a large number of connection conductors. The connection conductor of package 7 is contact 1
Contact them on a one-on-one basis. Next, package 7
Press the presser plate 3 onto it. Thereafter, the hook member 4 is rotated and hooked onto the tip of the presser plate 3. In this way, the presser part 9 of the presser plate 3 presses the package cage 7,
The connecting conductor is brought into reliable contact with the contact 1.

[Problem that the invention attempts to solve]

However, if the package 7 is attached to the socket body 2,
When attaching the contact to the contact plate, the holding plate 3 must be pushed down strongly with a force that counters the repulsive force of the contact 1, and the hook member 4 must be engaged with the tip of the holding plate 3, which makes the work difficult and The problem is that it requires a lot of force.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a connector for a plate-shaped circuit body that is easy to connect and requires less force.

[Means and actions for solving problems]

According to the present invention, in a connector for connecting a plate-shaped circuit body having a circuit element and a connecting conductor, a socket body that receives the plate-shaped circuit body on one side and a socket body that contacts the above-mentioned connecting conductor. A contact built into the socket body, a holding plate pivotally attached to one end of the socket body so as to be able to face one surface of the plate-shaped circuit body, and one end rotatable to the other end of the socket body. a pivot member attached to the pivot member, and a lever rotatably pivoted to the other end of the pivot member, the lever having an additional portion near the pivot point, and the lever having an additional portion near the pivot point, There is obtained a connector for a plate-shaped circuit body, characterized in that the above-mentioned plate-shaped circuit body is pressed and held on the upper surface of the connector by the additional portion of the lever to prevent the plate-shaped circuit body from floating up.

〔Example〕

1 and 2 show an embodiment of the connector for a plate-shaped circuit body of the present invention. The illustrated connector has a large number of electrically conductive and elastic contacts 11 and a socket body 12 incorporating these contacts 11. Socket body 1
2 is made using electrically insulating material. A slightly recessed package mounting portion 16 is formed on the upper surface of the socket body 12. The contact portions of a large number of contacts 11 protrude from the peripheral area of the package mounting portion 16 . A package 17 is attached to the package attachment section 16. Package 17 is
It has a circuit element such as an IC or an LSI, and a large number of connection conductors (not shown). The connection conductors are arranged so as to face the contacts 11. When the package 17 is attached to the package mounting section 16, the connection conductor is connected to the contact 1.
1 is contacted in one-to-one correspondence.

A package 1 is attached to one end of the socket body 12.
A presser plate 20 for pushing the package 7 into the package mounting portion 16 is rotatably pivoted. Presser plate 20
has a pivot portion 21 at one end thereof. A pivot portion 21 of the presser plate 20 is pivotally attached to a side wall surface 25 of the socket body 12 by a pivot point 22 . The presser plate 20 has a flat portion 27 at the other end, that is, at the end opposite to the pivot portion 21 . Further, the presser plate 20 is formed with a pair of presser plates 28 for pressing down and holding the package cage 17 from its upper surface.

A lever 32 is rotatably attached to the side wall surface 25 at the opposite end of the socket body, that is, at the end opposite to the pivot point 22, via a pivot member 30 made of bar material. . The lever 32 is connected to the socket body 12.
A side frame portion 33 that can face the side wall surface 25 of
It has an additional part 38 that is pivotally mounted, and an upper frame part 39 that can face the upper surface of the presser plate 20. The upper surface of the portion of the socket body 12 to which one end of the pivoting member 30 is pivotally connected is a shoulder surface portion 4 that is slightly lower than the upper surface of the other portion.
It is considered to be 0. The flat portion 27 of the presser plate 20 may be opposed to the upper surface of the shoulder surface portion 40 .

Next, the operation of attaching the package 17 to the socket body 12 will be explained with reference to FIGS. 4 to 7.

First, with reference to FIGS. 4 and 5, press plate 2
Place the package 17 on the socket main body 12 with the lever 32 and the lever 32 raised. Next, presser plate 2
0 about the pivot point 22 as a fulcrum in the direction of the arrow a, and the presser plate 20 is brought down to the upper surface of the package cage 17. In this state, the lever 32 is moved around the socket body 12 using the pivot points 35 and 36 of the pivot member 30 as fulcrums.
It is pulled up to above the shoulder surface part 40 of. In this state, the additional part 38 of the cover 32 and the socket body 1
The flat portion 27 of the holding plate 20 is inserted between the upper surface of the shoulder surface portion 40 of No. 2 and the upper surface of the shoulder surface portion 40 of No. 2. After that, lever 3
2 in the direction of arrow b to obtain the state shown in FIG.
The tip of the additional portion 38 is applied to the socket main body 12 by the lever principle. the result,
As shown in FIG. 7, the package 17 received in the socket body 12 is pressed against the contact 11 and held. Finally, as shown in FIG. 8, since the tip of the additional part 38 forms the straight part 41, the upper surface of the flat part 27 of the presser plate 20 and the straight part 41 face each other. There is no need to worry about the lever 32 rising up.

[Effect of idea]

As described above using the embodiments, according to the connector for plate-shaped circuit bodies of the present invention, connection of plate-shaped circuit bodies is performed by rotating and linearly moving the holding plate and rotating the lever. Therefore, the connection work is easy and requires less force.
