Description

Technical Field

[0001] The invention relates to the field of connectors, and in particular to an automated welding process for LVDS connectors. Background Art

[0002] In the prior art, LVDS connectors are widely used for connection between circuit boards and hosts. In the actual preparation process, after the connector terminals are injection molded and assembled with the metal shell, they are sent to the next process. The connector needs to be connected to the wire before it can be connected to the host. The existing technical solution for this process is: punch out the terminals through a stamping die. Figure 6 As shown in the material strip, the position of the conducting pin on the material strip is determined by the position of the terminal that needs to be grounded for each connector. However, due to the different performance of the connectors, the positions of the terminals that need to be grounded are also different. Therefore, different connectors need to be re-molded and then terminals at different positions are punched out. Then the entire material strip is placed in the connector, and then the material strip is welded to the metal shell through HOT BAR welding, and the wires are welded to the ungrounded terminals. The biggest problem with the above method is that it is not flexible. Due to the large number of terminals and grounding at different positions, more molds need to be opened for welding, which greatly increases the cost. Summary of the invention

The first clamping part 7 is an open square structure, and the second clamping part 8 is also an open square structure. The two are clamped together, and the two groups of opening structures form a receiving cavity 9 for the insertion of the driving rod 10.

In order to further increase the connection and operation stability of the driving rod 10, a piercing part is provided on the first clamping part 7. The piercing part is pressed down into the receiving cavity 9 and pressed on the side wall of the driving rod 10 to ensure the stable connection of the end of the driving rod 10 in the receiving cavity 9.
