Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a connector for mounting and connecting a plate-shaped circuit body such as a package such as an IC or an LSI to another printed board or the like.

[Conventional technology]

Some packages for ICs, LSIs, etc. have connection pads instead of connection lead wires at the ends. When mounting and connecting such a package to other printed circuit boards, etc., please refer to Figures 3 and 4, for example.
A connector as shown in the figure is used. In that connector, a number of contacts (not shown)
The package 2 was placed on the insulator 1 incorporating the package 2 so that its connection pad (not shown) was in contact with the contact, and a cover 4 having a plurality of elastic pieces 3 was placed over the package 2. cover 4
By connecting one end to the insulator via the pivot joint 5 and hooking and fastening the other end to the insulator, the package 2 is pressed against the insulator 1 by the plurality of elastic pieces 3 on the cover 4, and the thickness of the package 2 is reduced. The error was absorbed and the connection pad was brought into pressure contact with the contact.

[Problem that the invention attempts to solve]

However, as shown in FIG. 5, the force P ₁ of the elastic piece 3 pressing the package cage 2 is supported by the pivoting part 5 and the hooking parts 6 and 7, and the force P 1 of the elastic piece 3 is The pivot portion 5 and the hooking portions 6 and 7 are held together with a force (2×P ₂ ) equal to 2×P ₁ ). Therefore, the pivot portion 5 may be deformed, causing difficulty in opening and closing the cover 4.

Furthermore, the pressing force of the elastic piece 3 changes due to abrasion of the pivot portion 5 due to opening and closing of the cover 4, and the connection pad cannot be reliably pressed into contact with the contact.

[Means for solving problems]

According to the present invention, an insulator for receiving a plate-shaped circuit body having a circuit element and a connecting conductor;
A contact built into the insulator so as to come into contact with the connecting conductor of the plate-shaped circuit body, a cover pivotally attached to one side of the insulator and placed over the plate-shaped circuit body, and a cover perpendicular to the pivoting side. Elastic pieces that are provided at the front and back positions on both sides of the top and that can press the plate-shaped circuit body against the insulator; and an engagement mechanism that engages the cover and the insulator with each other in the opening direction of the cover when the cover is placed on the cover. The engagement mechanism includes an engagement portion provided on the insulator, and an arm extending from a pivoting portion of the cover along a side surface of the insulator, and engages with the engagement portion. an engaged portion;
There is obtained a connector for a plate-shaped circuit body, characterized in that the engagement mechanism is provided at a position corresponding to the center of the pressing contact of the elastic piece at the front and rear positions.

〔Example〕

Hereinafter, the parts of the present invention that are different from the conventional ones will be explained using FIG.

Reference numeral 10 denotes an engaging portion having an outwardly downwardly sloped portion 10′, which is provided on both side surfaces 1′ of the insulator at positions corresponding to the center of the pressing contacts of the elastic pieces 3′, 3″ at the front and rear positions, respectively. Reference numeral 11 denotes an operating arm having an operating part 12, which extends from the pivoting part 5 along the side surface 1' of the insulator on which the engaging part 10 is provided, and is integrated with the cover 4. Reference numeral 13 indicates an engaging part. Part 1
0 and constitutes the engagement mechanism 14, and is formed on the operating arm 11.

In such a configuration, in order to open the cover 4 from the state shown in FIG.
After removing the engaged part 13 from the engaging part 10, lift it in the direction away from the package 2. As a result,
The cover 4 becomes open.

Further, in order to close the cover 4, it is sufficient to push the operating section 12 in the direction of the package 2 from the above-mentioned open state. Then, the operating arm 11 is once pushed outward by the inclined part 10' of the engaging part 10, and then
The engaged portion 13 engages with the lower surface of the engaging portion 10 . As a result, the cover 4 is locked in the closed state.

Next, the force relationship between the elastic piece 3 and the engagement mechanism 14 will be explained. In FIG. 2 viewed from the side surface 1' of the insulator 1, the engagement mechanism 14 is located near the center of the pressing contacts of the elastic pieces 3' and 3'' at the front and rear positions, so that the The force (2×P ₁ ) of the pieces 3', 3'' is held by the force P ₂ of the engagement mechanism 14.

Therefore, almost no force acts on the pivot portion 5.

[Effect of idea]

As described above, according to the present invention, the connector structure has an engagement mechanism that integrates the cover and the insulator near the center of the pressing contact of the elastic piece that presses the plate-shaped circuit body. Since almost no force acts on the pivot joint with the insulator, deformation of the pivot joint can be prevented, the plate-shaped circuit body is reliably pressed against the insulator, and electrical connection is ensured.
