In actual application, the stepped screw 11 passes through the second O-ring 12, the end cap 3, the second through hole 2-1 opened on the rubber sleeve 2 and the first through hole 1-1 opened on the housing 1, and then connects and fixes to the threaded hole 8-3 on the bracket 8. The bracket 8 is connected to the screw post 3-2 by the screw 9.

[0031] like Figure 3As shown, in another preferred embodiment of the present invention, the end cap 3 is provided with a fourth through hole 3-5, the fourth through hole 3-5 is provided with at least a first plane 3-5-1, the corresponding position of the terminal 4 is provided with a matching second plane 4-1, and the terminal 4 is connected to the nut 7 provided in the end cap 3 by thread.

[0032] In this embodiment of the present invention, the arrangement of the first plane 3-5-1 and the second plane 4-1 makes the fourth through hole 3-5 and the terminal 4 not circular. The two work together to prevent the terminal 4 from rotating. Preferably, in this embodiment of the present invention, the terminal 4 is made of plastic.

[0033] like Figure 3 As shown, in another preferred embodiment of this utility model, at least one breather 10 is also installed on the end face of the end cap 3. The breather 10 is used to adjust the pressure difference between the inside and outside of the lamp. Specifically, a fifth through hole 3-6 is provided on the end face of the end cap 3, and a second protrusion 3-4 is provided on the end cap 3 at the position corresponding to the fifth through hole 3-6. The breather 10 is installed in the second protrusion 3-4, and the breather 10 has a tubular structure.

[0034] In this embodiment of the present invention, the number of the breather 10 is set to one, but in actual application, it can also be set to multiple. The breather 10 can be made of silicone material.
