Description

Terminal strip of card edge connector and method for cutting same

The invention relates to a card edge connector and a process thereof, in particular to a terminal strip of a card edge connector and a method for breaking the same.

According to the conventional card edge connector, especially for the memory card module connector, the soldering portion of the same row of terminals extending from the lower end of the connector body is often made up of different positions of the corresponding pins. The dislocation configuration is different, so that the terminal must pass through a plurality of procedures, or thus interference with the terminal soldering portion, in the process of breaking the material.

Since the connector terminals are first formed through a terminal strip to be formed thereon, the same row of terminals are inserted into a predetermined terminal slot in the connector body or directly wrapped on the contact portion of the row of terminals. After the connector body is molded, the terminal strip and the terminals are cut off; in the process of breaking the material, because the soldering portion of the terminal is usually bent and formed by the portion on the terminal strip, it is located. Each hole on the terminal strip has a contour or a size that matches the welded portion of the terminal, so that the terminal strip is easily deformed by the interference of the welded portion and the hole during the process of breaking the material through the bending, and only a slight The deformation may affect the forming angle and the alignment position of the welded portion, which may cause problems such as the fact that the connector is easily misaligned due to the deviation of the pin in the future. .

Therefore, in order to overcome the above problems, the conventional method can only be completed by dividing the above process into two processes; that is, the same terminal strip is formed on the same row of terminals on the same side, and the welded portion is biased toward the other. The terminal on one side is made on the other terminal strip. After inserting each terminal on the terminal strip into the connector body, the terminal strip is bent and cut off toward the back side of the terminal strip. After the completion, the other terminal strip is inserted into the connector body in the same manner, so that the two-pass program can be passed to avoid the problem that the same row of terminals interfere with the welded portion during the break due to the dislocation configuration of the welded portion.

However, since the same row of terminals must pass through the two-pass program, and the general card edge connector usually consists of two rows of terminals, at least four processes must be completed in the process of breaking the material. Therefore, the above-mentioned method is obviously time-consuming and labor-intensive, and the connector body is not formed by the overmolding method, and the connector body cannot be formed by the overmolding method, which results in limitation in the selection of the process method.

In view of the above, the present inventors have made an effort to improve and solve the above-mentioned shortcomings, and have devoted themselves to research and cooperate with the application of the theory, and finally proposed a present invention which is reasonable in design and effective in improving the above-mentioned defects.

The main object of the present invention is to provide a terminal strip of a card edge connector and a method for breaking the same, which only need to be completed by one terminal material for the same row of terminals on the card edge connector, and can avoid It is known that the welding end of the interference terminal is missing, and only one procedure is required for the same row of terminals, thereby shortening the process of the terminal on the broken material.

In order to achieve the above object, the present invention provides a terminal strip for a card edge connector The utility model comprises a material strip body and a plurality of terminals integrally connected to the strip body, wherein the terminals are collectively located on the same side edge of the strip body to respectively correspond to the plurality of terminal blanking holes formed on the strip body, and the respective terminals One end is the contact end away from the strip body, and the other end is the welding end facing the strip body, and the welding end is formed by the corresponding terminal blanking hole; wherein the welding end of each terminal faces the strip body respectively The welding end of the terminal which is bent outside the surface and which is bent toward the same surface of the strip body forms a reaming portion having a larger contour on the corresponding terminal blanking hole.

In order to achieve the above object, the present invention provides a method for breaking a terminal of a card edge connector, the steps of which are as follows: a) preparing a card edge connector according to any one of claims 1 to 3. a terminal strip; b) an insulative body is disposed on the contact end of each terminal of the terminal strip; c) the strip body of the terminal strip is bent toward a surface thereof to face the same surface The welded ends of each of the bent terminals pass through the corresponding reaming portions thereof until the strip body is broken.
