Description
Technical Field
The present utility model relates to a flexible circuit board, and more particularly to an improved structure of a flexible circuit board.
Background
As shown in fig. 10, there is a conventional flexible circuit board (Flexible Printed Circuit, FPC) which includes a main body 31, wherein a clamping portion 32 is disposed at a front end of the main body 31, and a plurality of conductive pads 33 are disposed on one surface of the clamping portion 32 at intervals, and when the clamping portion 32 is inserted into a connector (not shown) on a printed circuit board, the plurality of conductive pads 33 are in contact with a plurality of conductive terminals in the connector to achieve conduction. In addition, rectangular concave portions are respectively disposed on two opposite sides of the fastening portion 32, and when the fastening portion 32 is inserted in a correct position in the connector, the concave portions can be fastened with the convex portions in the connector, so as to lock the connection state of the fastening portion 32 and the connector.
In order to facilitate the determination of whether the fastening portion 32 is inserted in the correct position in the joint, the conventional determination method uses a white paint line 34 printed on the main body 31 as a determination standard, when the fastening portion 32 is inserted in the joint, if there is a gap between the white paint line 34 on the main body 31 and the edge of the joint, it means that the fastening portion 32 and the joint are not connected in place; if the white paint line 34 on the main body 31 is flush with the edge of the joint, the plurality of concave parts will clamp with the plurality of convex parts in the joint, which means that the clamping part 32 is connected with the joint in place.
However, since the conventional judgment of whether the white paint line 34 on the main body 31 is flush with the edge of the joint is performed by human eyes, erroneous judgment is likely to occur, and it is impossible for a manufacturer to quickly confirm whether the locking portion 32 and the joint are connected in place at the time of assembly, so that the working time for judging whether the insertion position is correct is prolonged.
With the technological progress, the automatic equipment (such as image identification) can replace the method of judging by using human eyes, so that the labor cost is effectively reduced and the assembly efficiency is improved. However, because the process accuracy of printing the white paint line 34 on the main body 31 still has a problem of large tolerance (+ -0.2 to 0.3 mm), the conventional flexible circuit board cannot meet the product requirement of high-accuracy alignment tolerance (++0.05mm), so that misjudgment still occurs frequently, and the improvement of the assembly efficiency is still limited.
Therefore, it is indeed necessary to provide a solution to the above-mentioned assembly efficiency limitation.
Disclosure of Invention
In view of the above-mentioned shortcomings of the prior art, a primary object of the present utility model is to provide an improved structure of a flexible circuit board, which can effectively solve the above-mentioned problem of limited assembly efficiency by improving a base element.
In order to achieve the above object, the present utility model adopts the main technical means that the improved structure of the flexible circuit board comprises:
the body is provided with a front end and a rear end;
a first clamping part arranged at the front end of the body;
two or more positioning portions provided on opposite sides of the first fastening portion in the width direction;
the two or more positioning parts are respectively provided with a positioning surface close to the front end of the first clamping and fixing part, and when the first clamping and fixing part is inserted in the correct position in the joint, the positioning surfaces of the two or more positioning parts are flush with the rear surface of the joint.
According to the structure, the two or more positioning parts are respectively arranged on the two opposite sides of the first clamping part in the width direction, so that when a manufacturer inserts the corresponding connector during assembly, the connection state of the first clamping part and the connector can be rapidly judged according to whether the positioning surfaces of the two or more positioning parts are flush with the rear surface of the connector, and the working procedure of using a white paint line in the prior art is replaced, and the assembly efficiency of the flexible circuit board and the connector is effectively improved.
