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 provided at one end of the socket body; a lever pivotally mounted on the upper surface of the other end of the socket body on both sides of the other end; a presser plate that can face one surface of the circuit body and can also move linearly along the plate-shaped circuit body; The retaining plate has an additional part projecting in a radial direction, and the holding plate has a pivoting part on both sides of the end facing the both side wall surfaces of the socket body, and the pivoting part has an elongated hole-shaped bearing part. is provided, and the bearing portion is fitted into a pivot point protruding from both sides of one end of the socket main body, and after the holding plate is opposed to one surface of the socket main body, the other end is inserted along the upper surface. by moving the holding plate to the lower side and positioning its tip below the attachment part, and rotating the lever, the attachment part of the lever presses the tip of the presser plate against the upper surface of the socket main body, A connector for a plate-shaped circuit body is obtained, characterized in that the plate-shaped circuit body is held by pressing the upper surface of the presser plate while preventing the plate-shaped circuit body from floating up.

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 a circuit element such as an IC or an LSI, and a large number of connection conductors (not shown). The connecting conductor is
They are arranged so as to face the contacts 11. The package 17 is attached to the package mounting section 16.
When the connecting conductors are attached to the contacts 11, the connecting conductors 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. Specifically, the pivot point 22 is located on the side wall surface 2 of the socket body 12.
5, and is engaged with a bearing portion 23 made of a long hole formed in the pivot portion 21. Thus, the presser plate 20 is rotatable about the pivot point 22 and slidable by the bearing portion 23.

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 has a pair of presser portions 28 for pressing down and holding the package cage 17 from its upper surface.

The opposite end of the socket body 12, i.e. the pivot point 22
A shoulder surface portion 30 that is slightly lower than the upper surface of the socket body 12 is formed at the opposite end.
A pair of pivot members 3 made of bar material are provided on the shoulder surface portion 30.
1 is fixed. The pivot member 31 is attached to the shoulder surface portion 3
It has pivot points 35 that extend upward from 0 and have pivot points 35 whose tips are bent inwardly. Pivot point 3
Both ends of a lever 36 are pivotally attached to the lever 5 . The lever 36 has a pair of elongated side frame portions 37 that can face the side wall surface 25 of the socket body 12.
, an additional portion 38 protruding near the pivot point 35 in a radial direction with respect to the axial direction of the pivot point 35, that is, in a direction perpendicular to the pair of side frame portions 37 and away from the pivot point 35; and a presser plate. It integrally has an upper surface frame portion 39 that can face the upper surface of 20.

Next, the operation of attaching the package 17 to the socket body 12 will be explained with reference to FIGS. 3 to 7.

First, referring to FIG. 3, the package 17 is placed on the socket body 12 with the presser plate 20 and lever 36 raised. Next, the presser plate 20 is rotated in the direction of arrow a about the pivot point 22, and the presser plate 20 is brought down to the upper surface of the package cage 17. In this state, the presser plate 20 is slid in the direction of arrow b as shown in FIG. In this way, the flat part 27 of the presser plate 20 is pressed against the lever 36 in the raised state.
and the upper surface of the shoulder surface part 30,
The state shown in FIG. 5 is obtained. Thereafter, when the lever 36 is tilted in the direction of arrow c to obtain the state shown in FIG.
be forced to. As a result, the package 17 received in the socket body 12 is pressed against the contact 11, as shown in FIG. Finally, as shown in FIG. 8, since the tip of the additional part 38 forms a straight part 40,
Since the upper surface of the flat portion 27 and the straight portion 40 face each other, there is no fear that the lever 36 will rise.

[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 achieved by rotating and linearly moving the holding plate and rotating the lever. Therefore, the connection operation is easy and requires less force.

Further, since the presser plate can be slid along the upper surface of the socket body, a large operating force is not required to operate the presser plate, and the operation can be performed reliably.
