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 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 requires a large amount of force. There is a problem in 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 one side 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 hook member pivotally mounted near the fulcrum of the lever and at a position offset from the fulcrum; the socket body has an engaging portion at the other end for receiving the hook 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 engagement portion while preventing 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 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. Package mounting part 16
The contact portions of a large number of contacts 11 protrude from the peripheral area. 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. The lever pivot point 28 has a pivot point 29.
A lever 27 is rotatably connected with the lever 27 as a fulcrum. The lever 27 includes a side frame portion 31 that can face the side wall surface 25 of the socket body 12, an additional portion 32 extending from the side frame portion 31 near the pivot point 29, and an upper frame portion that can face the top surface of the presser plate 20. It has 33.

A U-shaped hook member 35 made of a rod is pivotally attached to the additional portion 32 at both ends thereof. That is, each end of the hook member 35 is pivotally attached to the additional portion 32 at a position near the pivot point 29 and offset from the pivot point 29 . On the other hand, an engaging portion 37 is formed at the opposite end of the socket body 12, that is, the other end opposite to the pivot point 22.
The engaging portion 37 is a portion for hooking the hooking member 35, and may be a groove formed on the lower surface 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 8. First, referring to FIGS. 4 and 5, the package 17 is placed on the socket body 12 with the presser plate 20 erected. Next, while rotating the lever 27 in the direction of the arrow a about the pivot point 29, the presser plate 20 is tilted in the direction of the arrow b about the pivot point 22. In this state, the hook member 35 is engaged with the engaging portion 37 as shown in FIG. Thereafter, when the lever 27 is tilted in the direction of arrow c to obtain the state shown in FIG. Press the package 17 that is in place against the contact 11. Eventually, as shown in FIG. 8, the pivot point 29 will be located on the outside of the socket body 12 from the line connecting the fulcrum of the hook member 35 and the engagement position 39, so the lever 27 will be raised. There's no need to worry about climbing up.

[Effect of idea]

As explained 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 hooking member with the engaging part and rotating the lever. , the connection work is easy and requires less force.

Furthermore, if the socket body is made of an electrically insulating material such as a resin material, the engaging portion can be molded at the same time as the socket body is molded, thereby simplifying the manufacturing process.

Furthermore, since the engaging portion can be formed over the entire width of one side of the socket body, the hooking member can be engaged with more parts, and a stable engaged state can be obtained.
