A limiting rib 10 is provided in each wire hole 11. The end of the limiting rib 10 close to the end of the wire hole 11 is provided with an inclination. A limiting block 13 is provided in the wire holes 11 connected to the front and rear of the base 7. The limiting block 13 is annular, and the inner diameter of the limiting block 13 is smaller than the diameter of the wire, and the inner wall of the limiting block 13 is inclined.

[0125] Buckles 9 are provided at the four corners of the base 7 , and the buckles 9 cooperate with the hooks 2 provided on the protective cover 1 .

[0126] A number of clearance grooves 12 are arranged on the inner side of the protective cover 1. The number of the clearance grooves 12 is the same as the number of the connecting pins 4. The clearance grooves 12 are used to make way for the back of the connecting pins 4 after the connecting pins 4 are inserted into the needle grooves 6 and pierce the wires.

[0127] The material of the protective cover 1 is plastic, and bosses 14 are arranged on both sides of the base 7 .

[0128] In summary, when the wire connector with a protective cover is used, first insert the wire into the wire hole 11, install the connecting needle 4 into the corresponding needle groove 6, and then press the connecting needle 4 with a tool to make the connecting needle 4 complete the piercing of the wire, and then install the protective cover 1 on the base 7, insert the fixing block 8 into the inner cavity of the fixing groove 3, and buckle the buckle 9 with the hook 2.

[0129] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection. "upper", "lower", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may change;

[0130] Secondly: In the drawings of the embodiments disclosed in the present utility model, only the structures related to the embodiments disclosed in the present utility model are involved, and other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of the present utility model can be combined with each other;

[0131] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
