The electrical connector is usually provided with a docking slot, commonly called a slot, in which a signal terminal for transmitting signals is disposed, and the docking slot is used for matching and docking with an external electrical connector to realize signal transmission. The butt joint groove of common electric connector is integrated into one piece on insulator to make the structure simpler, save the equipment process, nevertheless, the colour in butt joint groove is unanimous rather than integrated into one piece insulator colour, can't set up alone, has restricted the colour setting in butt joint groove, like the insulator structure shown in the chinese utility model patent attached figure 1 that application number is 201320407405.8. If the color spraying is carried out on the electric connector butt joint groove part, the electric connector is small in structure, so that the process is complex, the cost is high, the complete coating of all the parts cannot be guaranteed, the butt joint groove needs to be frequently butted with an external electric connector, and after the electric connector is used for a long time, the color of the contact part is easy to fade.

As the function integration of electronic products gradually increases, a plurality of mating slots are integrated in most electrical connectors. An electrical connector having a plurality of docking slots is generally used in an electronic device having a high integration level, such as a server, a switch, or a router. Conventional electrical connectors having a plurality of mating slots each having the same transmission rate or transmission function, therefore, a user does not need to distinguish the mating slots. However, as the functional requirements of the electrical connector are diversified, one or more of the mating slots of the electrical connector with a plurality of mating slots may be set to have different transmission rates or transmission functions, and at this time, if the mating slots of the electrical connector cannot be visually distinguished, the user may be bothered greatly.
