[0027] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] Example 1:

[0029] like Figures 1 to 5As shown, the clamping type wire injection connector of this embodiment includes a lamp housing 1, a wire connector 2 and a clamping block 4 that is inserted through the lamp housing 1; a mounting hole 5 is provided on one wall of the lamp housing 1, and one end of the wire connector 2 is inserted into the lamp housing 1 through the mounting hole 5;

[0030] like Figure 2 As shown, the wire connector 2 inserted into the lamp housing 1 is provided with a snap-in groove 7, and the snap-in block 4 can be snap-fitted with the snap-in groove 7. The snap-in block 4 is abutted against the inner wall of the lamp housing 1 to fix the wire connector 2 on the lamp housing 1. Specifically, the snap-in block 4 is provided with a snap-in opening 8 for inserting the snap-in groove 7, and the inner wall of the snap-in block 4 is provided with a limiting ridge 9 that can snap-fit ​​with the snap-in groove 7. That is, during the assembly process, after the wire connector 2 passes through the mounting hole 5, the snap-in opening 8 of the snap-in block 4 is directly placed downward on the snap-in groove 7 and pressed down with force. The snap-in opening 8 will expand slightly, and after being fully snapped with the snap-in groove 7, it will reset and rebound under the action of its own elasticity to prevent it from falling out. The entire installation process is simple and convenient, and has higher production efficiency than the existing nut locking method.

[0031] Further, if Figure 4 As shown, in order to further improve the convenience of installation, wedge-shaped plug-in ends 10 are respectively provided at both ends of the limiting protrusion 9 near the snap-in opening 8. The wedge-shaped plug-in ends 10 can facilitate the insertion of the limiting protrusion 9 into the snap-in groove 7, that is, the design of the wedge-shaped plug-in ends 10 can play a guiding role, which can make the snap-in of the snap-in block smoother.

[0032] In this embodiment, the limiting ridge 9 is set at the middle position of the inner wall of the clamping block 4. At this time, the overall structure is fixed and relatively stable, or according to design requirements, the limiting ridge 9 is set at a position deviated from the middle of the inner wall of the clamping block 4. When the limiting ridge 9 is closer to the outside, the clamping block 4 can be compressed a little more, which can further improve the sealing effect.

[0033] like Figure 3 As shown, the wire connector 2 is provided with an abutting end 6 where it abuts the outer wall of the lamp housing 1. A rubber gasket 3 is also provided between the abutting end 6 and the outer wall of the lamp housing 1 to further improve the sealing effect. In this embodiment, the abutting end 6 is configured as a hexagon, and the clamping block 4 is made of rubber or plastic.

[0034] Example 2:

[0035] Compared with Example 1, in this embodiment, the width of the clamping block 4 is the same as the length of the wire connector 2 extending into the lamp housing 1. When the end faces of the clamping block 4 and the wire connector 2 are clamped together, they are in a flush state, which can improve the efficiency of assembling the clamping block 4. At the same time, it is more convenient to determine whether the clamping block 4 is effectively installed, that is, the radial position relationship between the clamping block 4 and the end face of the wire connector 2 can be clearly seen.

[0036] The above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. Ordinary technicians in the relevant technical field may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also fall within the scope of the present invention, and the scope of patent protection of the present invention shall be defined by the claims.
