Piece is connected by fastener.
Preferably, the wiring case lid ground strip is bilayer；The internal layer of the double-layer wiring case lid ground strip flips up,
Abutted with outer layer；When the wiring casing ground strip passes through fastener with wiring case lid ground strip, the double-layer wiring case lid connects
The internal layer of ground piece abuts with wiring casing ground strip；The seal is arranged on the outer layer of wiring casing and wiring case lid ground strip
Between.
Preferably, the thickness of the double-layer wiring case lid ground strip be equal to wiring case lid thickness and seal thickness it
With.
Preferably, the outer layer thickness of the wiring case lid ground strip is identical with the thickness of wiring case lid；The wiring case lid
The internal layer thickness of ground strip is identical with the thickness of seal.
Preferably, the seal is rubber.
Due to the utilization of above-mentioned technical proposal, the present invention has following advantages compared with prior art：
The junction box of the present invention, it is by being provided with wiring casing ground strip below wiring casing, being provided with below wiring case lid
Wiring case lid ground strip, wiring casing ground strip is connected with wiring case lid ground strip by fastener, to be grounded effect,
The setting of grounding base and ground wire is eliminated, reduces the manufacturing cost of junction box, meanwhile, junction box installation and dismounting, easily
In maintenance and maintenance.
