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 for ICs, LSIs, and the like are provided with connection contacts at their ends as connection conductors, for example, instead of using connection lead wires. 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 not connected to the socket body 2,
When attaching the contact to the contact plate, the hook member 4 must be engaged with the tip of the presser plate 3 while strongly pushing down the presser plate 3 with a force that counters the repulsive force of the contact 1, which makes the work difficult and requires a large amount of force. There is a problem that it requires

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 its upper surface and a socket body that contacts the above-mentioned connecting conductor. A contact built into the socket body, a presser plate pivotally attached to one end of the socket body and capable of facing one surface of the plate-shaped circuit body, and a lever pivotally attached to the rotating end of the presser plate. , a hooking member pivotally attached to the other end of the socket body, the lever having an engaging portion for receiving the hooking member near a fulcrum of the lever and at a position offset from the fulcrum, and the hooking member There is obtained a connector for a plate-shaped circuit body, characterized in that the plate-shaped circuit body is pressed and held while being engaged with the engaging portion to prevent the plate-shaped circuit body from floating up.

〔Example〕

1 to 3 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 12
is made of 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 circuit elements such as ICs and LSIs and a large number of connection conductors 18. The connection conductor 18 is arranged so as to face the contact 11. When the package 17 is mounted on the package mounting portion 16, the connection conductors 18 are brought into contact with the contacts 11 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 via a pivot point 22.

A pair of lever pivot portions 28 for pivotally attaching the lever 27 are provided at the other end of the presser plate 20, that is, on the free end side. A lever 27 is rotatably connected to the lever pivot portion 28 with a pivot point 29 as a fulcrum. The lever 27 has a side frame portion 31 that can face the side wall surface 25 of the socket body 12, and a pivot point 29.
It has an additional part 32 extending from the side frame part 31 near the side frame part 31, and an upper frame part 33 that can face the upper surface of the presser plate 20.

An engaging portion 35 is formed in the additional portion 32 at a position near the pivot point 29 and offset from the pivot point 29 . The engaging portion 35 may be a notch formed from one end of the additional portion 32. These engaging portions 35 are provided with U-shaped hook members 3 made from bar materials.
7 is engaged. Both ends of the hook member 37 are pivotally connected to the side wall surface 25 at the opposite end of the socket body 12, that is, at the end opposite to the pivot point 22. As a result, the portion between both ends of the hooking member 37 has a shoulder surface portion 3 formed lower than the upper surface of the socket body 12.
8 and a position facing the front wall surface 39 of the socket body 12.

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

First, referring to FIG. 4, the package 17 is placed on the socket body 12 with the presser plate 20 raised. Next, while rotating the lever 27 in the direction of the arrow a with the pivot point 29 as the fulcrum, the presser plate 20 is tilted in the direction of the arrow b with the pivot point 22 as the fulcrum. In this state, the hook member 37 is engaged with the engaging portion 35 as shown in FIG. After that, when the lever 27 is tilted in the direction of arrow c to obtain the state shown in FIG.
0 is pressed toward the socket body 12 by the lever principle, and as a result, the socket body 1
The package 17, which is received by 2, is pressed against the contact 11. Ultimately, as shown in FIG.
There is no need to worry about the lever 27 rising up because it will be located outside of the lever 27.

[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 aligning the hook member with the engaging part and rotating the lever. Therefore, the connection work is easy and requires less force.

Furthermore, when the hook member is engaged with the engagement portion, the state of engagement can be confirmed even from above the socket body, so that workability is improved and the package can be installed reliably.

Furthermore, the engaging part can be molded at the same time when the lever is molded from a resin material, and when the lever is punched and molded from a metal plate, it can be punched out at the same time, simplifying the manufacturing process. .
