technical field

The utility model relates to a shell device of a tri-proof lamp.

Background technique

Existing lamps generally include a base and a top cover. A reflector is arranged in the base, and the connecting terminals of the lamp are arranged on the reflector. When wiring, the upper cover of the lamp is first opened relative to the base, and then the external power line and the wiring are connected. Terminals are connected, and then the base and the upper cover are fixed. The wiring of lamps with this structure is cumbersome and inconvenient to operate. In addition, most of the lamps currently used outdoors have waterproof functions. Using the lamps with the above structure, maintenance or replacement of the circuit It is necessary to open the upper cover relative to the base many times, which will easily affect the overall sealing performance of the lamp.

Chinese invention patent application (application number: 201010171225.5, application date: 2010.05.12) discloses a wiring structure of a lamp, which is provided with a circuit board on the inner surface of the upper cover, and a terminal is provided at the end of the circuit board. Correspondingly, a first through hole is provided at the terminal, and the first through hole is closed by a plug made of a flexible material, and a second through hole for passing an external power line is opened on the side wall of the plug. With the above structure, Although there is no need to open the entire upper cover of the lamp relative to the lamp holder during wiring, which provides certain convenience for wiring and makes the lamp have a better waterproof effect, but because the upper cover has a certain height, when the plug is opened from the first pass There is still a lot of inconvenience when wiring at the holes, which can easily lead to problems such as weak line connections.

Chinese invention patent (application number: 201110213835.1, application date: 2011.07.29) discloses a wiring structure, that is, a junction box is arranged at both ends of the lamp body, the junction box includes a box body and a box cover, and the box body is detachably connected On the lamp body, the wiring part is set in the box body. When wiring, the box cover is opened relative to the box body. When the wiring is completed, the box body and the box cover can be fastened. Compared with the conventional wiring method , although it has avoided opening the upper cover of the entire lamp, it still needs to open the cover for wiring. The space of the junction box is limited, which brings some inconvenience to the operation of the wiring personnel.
