Abstract
The utility model discloses an explosion-proof cable compacting and sealing connector comprising an inlet connector and an intermediate connector. Cavities used for accommodating a cable are disposed on the centers of the inlet connector and the intermediate connector. The two ends of each of the inlet connector and the intermediate connector are equipped with threads and the inlet connector and the intermediate connector are in threaded connection. The front end of the inlet connector is fixed by screw nut. The rear end of the intermediate connector is fixed by a compression nut. A first sealing ring is disposed in the cavity of the inlet connector. A spacer and a second sealing ring are arranged in the cavity of the intermediate connector. A hammer plated sleeve is arranged between the inlet connector and the intermediate connector. The two ends of the hammer plated sleeve are accommodated in the cavities of the inlet connector and the intermediate connector, respectively. The explosion-proof cable compacting and sealing connector is good in impermeability and fireproof performance, long in service life, and high in practical value.
Description
Technical field
The utility model relates to machine components field, specifically a kind of for clamping the seal nipple of anti-explosion cable.
Background technology
Cable joint is widely used in that plant equipment is electric, the fixing and protection of the electric wire of marine electrical equipment, corrosion protection equipment.Its Main Function is the fastening of cable and sealing, the cable joint that also has some Code in Hazardous Special Locations to use.As the Waterproof connector of cable of shielding, the applicable cable with screen; Be applicable to the anti-explosion cable water joint of the deathtraps such as mine etc.
Because anti-explosion cable joint is applied in deathtrap, therefore its quality requirement is wanted to high, existing anti-explosion cable joint is more and more perfect selection quality and application aspect development, but it still comes with some shortcomings, existing anti-explosion cable joint tighness is good not, fire protecting performance is low, and security performance is not high enough, falls short of useful life etc.
Utility model content
The purpose of this utility model is the defect that overcomes above-mentioned prior art, and a kind of good airproof performance is provided, and fire line is high, and fail safe is good, the anti-explosion cable joint of long service life.
The technical solution of the utility model is achieved in that a kind of anti-explosion cable clamps seal nipple, comprise entrance connector and intermediate connector, the middle part of described entrance connector and intermediate connector is provided with for holding the cavity of cable, its two ends are provided with screw thread and described entrance connector and intermediate connector and are threaded connection, the rear end of described entrance connector front end and intermediate connector is fixed by nut and clamp nut respectively, in described entrance connector cavity, be provided with the first sealing ring, in described intermediate connector cavity, be provided with pad and the second sealing ring, between described entrance connector and intermediate connector, be provided with hammer plating cover, and described hammer plating cover two ends are contained in respectively in described entrance connector and intermediate connector cavity.
Further, described entrance connector and intermediate connector all adopt carbon element steel or stainless steel to make.
Further, the front-end and back-end of described entrance connector all adopt external screw thread, and the front end of described intermediate connector adopts internal thread rear end to adopt external screw thread.
Further, the front end of described entrance connector adopts external screw thread rear end all to adopt internal thread, and the front end of described intermediate connector adopts external screw thread rear end to adopt external screw thread.
Entrance connector in the utility model and intermediate connector all adopt carbon element steel or stainless steel to make, in described entrance connector cavity, be provided with the first sealing ring, in described intermediate connector cavity, be provided with pad and the second sealing ring, guaranteed the sealing of cable joint, adopt stainless steel and carbon steel material to manufacture fire protecting performance good simultaneously, long product lifecycle, practical value is high.
Accompanying drawing explanation
Fig. 1 is the structural representation (containing partial sectional view) that a kind of anti-explosion cable of the utility model clamps seal nipple.
Embodiment
Below in conjunction with accompanying drawing, concrete case study on implementation of the present utility model is illustrated:
As shown in Figure 1, a kind of anti-explosion cable clamps seal nipple, comprise entrance connector 3 and intermediate connector 4, particularly, described entrance connector 3 and intermediate connector 4 all adopt carbon element steel or stainless steel to make, and have guaranteed that described entrance connector 3 and intermediate connector 4 are firm in structure, and quality is good, fire line is good, long service life.At the middle part of described entrance connector 3 and intermediate connector 4, be provided with for holding the cavity of cable, in described cavity, accommodate armoured cable 9.
Preferably, at described entrance connector 3 and intermediate connector 4 two ends, being provided with screw thread for being connected and described entrance connector 3 and intermediate connector 4 is threaded by described, particularly, the front-end and back-end of described entrance connector 3 all adopt external screw thread, the front end of described intermediate connector 4 adopts internal thread and rear end employing external screw thread accordingly, and the internal thread of described intermediate connector 4 front ends screws the front end at described entrance connector 3; In addition, the front end of described entrance connector 3 adopts also can be arranged to external screw thread and rear end employing internal thread, accordingly, the front end of described intermediate connector 4 adopts external screw thread rear end to adopt external screw thread, and the internal thread rotation of described entrance connector rear end is on the front end external screw thread of described intermediate connector 4.
At described entrance connector 3 front ends, by nut 1, be locked, the rear end of described intermediate connector 4 is locked by clamp nut 6, and between described entrance connector 3 and intermediate connector 4, be provided with hammer plating cover 5, and described hammer plating cover 5 two ends are contained in respectively described entrance connector 3 and intermediate connector 4 cavitys.In described entrance connector 3 cavitys, be also provided with the first sealing ring 2, in described intermediate connector 4 cavitys, be provided with pad 7 and the second sealing ring 8, described the first sealing ring 2 can seal the front end of described entrance connector 3, described pad 7 and the second sealing ring 8 can seal the rear end of described intermediate connector 4, make the better tightness of whole seal nipple.
As described above, it is only preferred embodiment of the present utility model, when not limiting the scope that the utility model is implemented with this, the simple equivalence of generally doing according to the utility model claim and utility model description changes and modifies, and all still belongs in the scope that the utility model patent contains.
