Description

Technical Field

[0001] The utility model relates to the technology of connector field, in particular to a connector which is convenient to process. Background Art

[0002] RJ45 consists of an RJ45 plug and an RJ45 socket. The connector composed of these two components is connected between the wires to achieve electrical continuity of the wires. The core of the RJ45 module is the modular jack. The gold-plated wire or socket hole can maintain a stable and reliable electrical connection with the modular socket spring. Due to the friction between the spring and the socket, the electrical contact is further strengthened as the plug is inserted. The jack body design adopts an integral locking mechanism so that when the modular plug is inserted, the interface between the plug and the jack can produce maximum pull-out strength.

[0003] There are 4 pairs of differential signal pairs on the RJ45 connector, and one of the differential signal pairs is located on the inner side of another differential signal pair. When the signal is transmitted, since the terminals are arranged in a single row, the distances from the terminals in the outer differential signal pair to the two terminals in the inner differential signal pair are different, resulting in different degrees of signal interference to the two terminals on the inner side. In order to solve this problem, the differential signal welding part will be divided into two rows during processing, and in order to ensure the capacitive coupling relationship between the two signal terminals in the differential signal pair, the distance between the welding ends of the two signal terminals needs to be close enough. When producing a connector with this structure, if the injection molding process is adopted, the pressure generated during the injection molding process will cause a contact short circuit between the two rows of terminals. Therefore, the terminals can only be plugged into the insulating body by plugging after injection molding. This method has a more cumbersome assembly process, which affects the overall processing efficiency, especially for connectors with smaller sizes, which are difficult to achieve mass production. Therefore, it is necessary to make further improvements to the existing connector structure. Utility Model Content
