It can be seen that, compared with the prior art, the terminal connector provided in the embodiment of the present invention has some functional modules built therein, and the conductive copper bar 3 is connected with the functional modules from inside of the terminal connector, which is beneficial to reducing internal routing of electrical equipment using the terminal connector and reducing routing length, reducing influence of the routing on internal space of the electrical equipment, and facilitating wire management during manufacturing and maintenance.
Preferably, in order to fix the functional module, a mounting groove for mounting the functional module may be provided in the housing 1, the size and shape of the mounting groove may be designed according to the size and shape of the functional module to be fixed, and the clamping structure may be designed according to the shape and characteristics of the functional module in the design process so as to facilitate the mounting.
