Description

Technical Field

[0001] The invention belongs to the technical field of communications, and in particular relates to a board-end connector. Background Art

[0002] Connectors can be divided into board-side connectors installed on circuit boards and wire-side connectors used to connect to wires according to their installation differences. Board-side connectors have the advantages of thin thickness, small size, and simple connection. With the continuous development of electronic technology, board-side connectors are gradually being used more and more frequently in electronic products. Figure 1 As shown, an existing board-end connector, this structure requires the inner insulator inside the shell to be cut into two halves, so that the integral inner conductor can be installed in the inner insulator, and the two cut inner insulators surround the integral inner conductor. However, this may cause the two inner insulators to not fit completely, and it is very difficult to press fit into the outer conductor with a gap in the middle, making assembly difficult and inefficient. In addition, this structural installation method adopts the method of welding the integral inner conductor to the PCB board, which has low processing efficiency and is not easy to replace. If there is a slight problem with the welding, it will cause the PCB board and the board-end connector to be scrapped, increasing the product cost. Therefore, there is an urgent need for a board-end connector that can solve the existing problems. Summary of the invention
