As the optimization technique measure, described fine rule perforation is one, and described thick line perforation is at least one.

As the optimization technique measure, have the extension on described base and the end cap, described thick line perforation and fine rule perforation are formed on the corresponding extension.Concrete, can form the thin-walled that cooperates with described folder thick line nut or the extruding of folder fine rule nut at the external port place of corresponding extension and at the inboard interior step of boring a hole that forms of this thin-walled, described folder thick line sealing ring, press from both sides the fine rule sealing ring and place on the corresponding step in abutting connection with described thick line perforation or fine rule.

As the optimization technique measure, described base has corresponding end face with end cap, at least one of the end face of this two correspondence annular groove is set, and described sealing ring places in this annular groove.

As the optimization technique measure, the profile of described base and end cap is the polygon prism shape.

The beneficial effects of the utility model are:

1, adopts the clamp seal head, can seal the terminal stud that need penetrate terminal box inside fully, need not auxiliary material such as glue.

2, compress sealing ring by screwing screw thread, the container cavity in the sealed terminal box well, erosion and destruction that the protection inner components is not subjected to extraneous water, vapour.

3, terminal box assembling only with hand threaded together need not other instrument equipments, easy accessibility.

Embodiment

Below in conjunction with Figure of description the utility model is described further.

A kind of waterproof junction box of the present utility model, shown in Fig. 1-4, it comprises base 1 and end cap 2, base 1 and end cap 2 are by being threaded, at the inside formation container cavity 3 of base 1 with end cap 2, between base 1 and end cap 2, put sealing ring 4 (as zero type circle) is arranged, (perforation 5 of thick line shown in Fig. 1-4 and fine rule perforation 6 are opened in respectively on base 1 and the end cap 2 offering thick line perforation 5 and fine rule perforation 6 on base 1 and the end cap 2 respectively, can exchange the position of thick line perforation and fine rule perforation according to the structure of base and end cap during concrete enforcement), be thick line perforation 5 configuration folder thick line nut 7 and folder thick line sealing rings 8, be fine rule perforation 6 configuration folder fine rule nut 9 and folder fine rule sealing rings 10.When wiring is installed, with fine rule pass folder fine rule nut 9, folder fine rule sealing ring 10 and and fine rule perforation 6, hand-tight make-up folder fine rule nut 9 promptly seals fine rule by folder fine rule nut 9 crushing clamp fine rule sealing rings 10; Thick line is passed folder thick line nut 7, folder thick line sealing ring 8 and thick line perforation 5, and hand-tight make-up folder thick line nut 7 promptly seals fine rule by folder thick line nut 7 crushing clamp thick line sealing rings 8; Connect thick line and fine rule by modes such as junction block or binding post or wiring boards, put sealing ring 4 between base 1 and end cap 2, linking together base and end cap also with tight base 1 of hand-screw and end cap 2 by screw thread, the 4 formation sealings of crush seal circle can will be sealed in the container cavity 3 through thick line and the fine rule that modes such as junction block or binding post or wiring board are connected.

As further improving and replenishing to technique scheme, the utility model also comprises following additional technical characterictic, though Fig. 1, the 2nd, preferred embodiment of the present utility model, but the utility model is not limited to this situation, according to specifically acting on they is selected for use on the described technical scheme of epimere when implementing the utility model:
