Property；Inlet wire cable passes sequentially through privates hole, the second wire guide and the first wire guide and enters box house, and inlet wire cable is twined
Copper busbar is connected to after on a bobbin, then by one end of inlet wire cable, then to connector inner button pressure cylinder, makes pressure cylinder
One end extruding elastic packing plug, one end of elastic packing plug reduces under the extruding at the trapezoidal end in inner chamber, make elastic packing plug with
Sealed between connector lug, while make to seal between the cable in the second wire guide and elastic packing plug, and pressure cylinder and connector it
Between be threaded connection, sealing is also very good, thus whole incoming seal joint is had good sealing, it is ensured that inlet wire
There is good sealing, explosion-proof is good between cable and casing；Sealing between outlet cable and casing is by going out linear sealing
Joint is completed, and principle is consistent with incoming seal joint, is not repeating herein.
As further improvement of the utility model, sealing gasket is provided between the casing and case lid, casing leads to case lid
Cross bolt flexible connection.Sealing gasket is set, makes the better tightness between casing and case lid.
As further improvement of the utility model, the reel is provided with baffle ring.Baffle ring is set, to control coiling position
Put.
The beneficial effects of the utility model are：
(1) setting of incoming seal joint and outlet seal nipple, it both ensure that the sealing at casing inlet-outlet line, it is ensured that
Good explosion-proof performance, while wiring is facilitated again, wiring process is simple, efficiency high；
(2) setting of reel, the cable connection of certain length has been reserved for follow-up electrically change, has made the electric simultaneous of casing
Capacitive is more preferable, reduces the follow-up cost electrically changed；
(3) connector is threadedly coupled by the external screw thread in its projection with casing, it is ensured that between connector and casing
Sealing；Pressure cylinder makes to seal between elastic packing plug and connector lug, while makes the cable and elastic packing plug in the second wire guide
