Description

Technical Field

[0001] The utility model relates to the technical field of terminal buckles, and more specifically, to a detachable buckle structure of a metal connector terminal. Background Art

[0002] The terminal buckle structure of the metal connector currently on the market is a one-time assembly of the terminal assembly buckle. When the metal wire fails, it is inconvenient to disassemble the terminal assembly. It is also easy to damage the terminal assembly during forced disassembly, thereby affecting the service life of the terminal assembly. To avoid this situation, it is necessary to install a terminal buckle that is easy to disassemble. For example, the patent of prior art announcement number CN110112598A discloses a detachable terminal buckle structure for a metal connector for an automobile. The first terminal clamp is tightly connected to the connector housing, and then the second terminal clamp is threadedly connected to the first terminal. The inner shielding ring is mounted on the base and tightly connected to the first terminal base and a C-type terminal buckle is installed on the C-type terminal buckle groove in the middle of the outer wall of the inner shielding ring. The terminal is then inserted into the connector housing. The terminal passes through the C-type limit clip, the terminal passes through the C-type terminal buckle and expands the C-type terminal buckle. The terminal is guided by the terminal guide ring to prevent the terminal from being installed upside down. At this time, the left middle part of the inner shielding ring is connected to the middle inclined surface of the first terminal base, the terminal is limited, and then the tail cover is put on the shielded cable from right to left and the left middle part of the tail cover is clamped with the right end of the connector housing, so that the terminal is locked in the connector housing.

[0003] When the above device is in use, the tail cover is removed from the connector housing and withdrawn from the tail cover, and then the second terminal holder is unscrewed, and the terminal or shielded cable is taken out for replacement or repair. There is no need to replace all the parts at once, and it can be reused repeatedly, saving costs. However, it uses a C-shaped limit clip to connect and fix the shielded cable and the terminal, which can easily cause the shielded cable and the terminal to detach during use, thereby affecting the stability of its installation and use.
