[0005] According to another embodiment of the utility model, further include the two limit strips and a buckle on the side wall of the lower casing, and the buckle is located between the two limit strips;

[0006] The ear is equipped on the side wall of upper casing, and the clamping hole for passing through the buckle is equipped on the ear, and the ear is fitted between the two limit strips.

[0007] According to another embodiment of the utility model, further include the clamping hook on the side of the upper casing, and the clamping hole one for inserting the clamping hook is equipped on the side of the lower casing.

[0008] According to another embodiment of the utility model, further include the clamping block is L-shaped clamping block.

[0009] According to another embodiment of the utility model, further include the clamping groove is T-shaped slot.

[0010] The utility model has the advantages that the square cover on the connector body is clamped tightly by the square hole composed of the U-shaped clamping groove in the upper casing and the lower casing, avoiding the relative shaking of the connector body and the protection shell. The clamping block at the tail end of the protection shell cooperates with the clamping groove on the connector body to improve the connection strength. The connection strength of the connector body and the protection shell is improved. BRIEF DESCRIPTION OF DRAWINGS

[0017] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the upper shell of this utility model; Figure 3 This is a schematic diagram of the structure of the lower shell of this utility model; Figure 4 This is a schematic diagram of the connector body of this utility model.

[0018] Combined with appendix Figure 1 and attached Figure 2 As shown, a low-voltage connector with a protective structure includes a connector body 1. A protective shell 2 is fixedly connected to the front end of the connector body 1. The protective shell 2 is composed of an upper shell 21 and a lower shell 22. The upper shell 21 and the lower shell 22 are provided with U-shaped slots 23 for forming square holes. The front end square cover of the connector body 1 fits into the square hole. The inner walls of the tail ends of the upper shell 21 and the lower shell 22 are provided with locking blocks 24. The outer wall of the connector body 1 is provided with slots 25 for inserting the locking blocks 24.

[0019] As attached Figure 3 As shown, the lower housing 22 has two limiting strips 26 and a buckle 27 on its side wall, with the buckle 27 located between the two limiting strips 26;

[0020] The upper housing 21 has a hanging ear 28 on its side wall. The hanging ear 28 has a card hole for passing through the buckle 27. The hanging ear 28 is engaged between two limiting strips 26.
