Film circuit board adapting device

Abstract

A film circuit board adapting device is provided with a central board and two symmetrical panels. An insulating frame encloses the periphery of the central board, a partitioned conductive part is arranged in the middle of the insulating frame, an insulating connecting portion of the conductive part is connected with the insulating frame, the conductive part can be made of conductive metal, conductive rubber or conductive silver paste, the top and the bottom of the conductive part partially project out of the insulating frame, a plurality of top projections are arranged on one side of the top of the central board, a plurality of bottom projections are also arranged on the other side of the bottom of the central board, the end faces of the panels are the same as the end faces of the central board, a plurality of sockets are arranged on one side of each panel and corresponding to the projections of the central board in position, other two sides of each panel are provided with two pairs of lugs at equal interval respectively, the lugs of the panel serving as the bottom are in staggered and scarf joint with the lugs of the panel serving as the top, a film circuit board is connected to the top or bottom of the central board in such way that small posts on the lugs of the panels are inserted into small slotted holes of the central board, and electric conduction is achieved through the conductive part.

Description

technical field [0001] The invention relates to a connector, in particular to a film circuit board transfer device. Background technique [0002] Between the known flexible circuit board and the membrane switch, the usual technology is to print strip lines made of silver paste on one side of the flexible circuit board, and use a wire as a connection, and one end of the wire is fastened to a One end of the clip, the clip is connected to the flexible circuit board through the other end. This kind of clip has a considerable width, and uses the four ear-shaped protrusions on the other end to pass through the corresponding positioning on the flexible circuit board. After the hole, pull the ear-shaped protrusion outward or inward to clamp the flexible circuit board, and use the clip to generate electrical connection to the strip line.

Problems solved by technology

[0002] Between the known flexible circuit board and the membrane switch, the usual technology is to print strip lines made of silver paste on one side of the flexible circuit board, and use a wire as a connection, and one end of the wire is fastened to a One end of the clip, the clip is connected to the flexible circuit board through the other end. This kind of clip has a considerable width, and uses the four ear-shaped protrusions on the other end to pass through the corresponding positioning on the flexible circuit board. After the hole, pull the ear-shaped protrusion outward or inward to clamp the flexible circuit board, and use the clip to generate electrical connection to the strip line. Due to the specificity between the two materials, clamping often occurs The entire buckle is out of contact, resulting in poor contact or misalignment; and because the current line has been shrinking, the pitch of the strip line is getting smaller and smaller. When it has reached one-tenth, if it is to be halved to 1.2mm , which is more difficult to solve in the manufacture of clips; in addition, if a pin-type connector is used, there will also be a gap problem, and the difference between them is too large or too small, which will affect the efficiency of the connection. , these conventional structures cannot meet the actual needs. In order to provide items that are more in line with actual needs, the inventors have carried out research and development to solve the problems that are easy to occur in the conventional use.
