Abstract
The utility model relates to a conductive sealing device with air pressure balancer, comprising an outer shell and an air cylinder provided within a shell. The air cylinder is internally provided with a piston on which an air valve and a sealing ring are provided. The air cylinder is provided with a piston baffle. The shell and the piston baffle are provided with a shell hole and a baffle hole which are connected with an inner cavity of air cylinder, respectively. The shell is internally provided with a raised ring. A groove is formed between the raised ring and the outer shell. The groove is internally provided with a sealing ring. The shell is further provided with a power interface and a copper contact pin. The utility model can balance the inner and outer air pressures of the luminaire so that it is good for keeping effective sealing for a long period. The groove with sealing ring in the shell is able to tightly match with a lamp tube port. The shell is easy to dismount, convenient to install, maintain or replace the light source or other parts in the lamp tube. The shell and the copper contact pin are formed into an integral structure so that it is able to further strengthen the sealing effect, improve the water-proof performance, reduce the possibility that the luminaire is destroyed because the water stream or rain enters into the lamp tube, and prolongs the service life of the luminaire. The utility model is suitable for the outdoor luminaire.
