Abstract
The utility model discloses a cable lead-in pressing device which comprises a pressing nut type cable lead-in device and a splitting type detachable cable anti-loosening device. The pressing nut type cable lead-in device comprises a pressing nut, a pressing ring, a sealing ring and a leveling pipe. The sealing ring is arranged on the internal side of the leveling pipe. The pressing ring is arranged on the external side of the sealing ring and closely clung to the sealing ring. The pressing nut is arranged on one side, which leads in a cable, of the leveling pipe. The cable anti-loosening device comprises cable pressing strips and an ox horn type fixing ring which is fixed on the pressing nut via a bolt. There are two cable pressing strips which are fixed on the ox horn type fixing ring via the bolt and the nut and used for tightly clamping and fixing the cable to prevent loosening. With the additionally arranged cable anti-loosening device, loosening situation of the cable in use can be effectively prevented so that safety is enhanced.
Description
Technical field
The utility model belongs to the electrical apparatus for explosive atmospheres field, specifically, is to introduce hold down gag about a kind of cable.
Background technology
Electrical apparatus for explosive atmospheres is introduced hold down gag and exactly cable is introduced to electric equipment, and does not change the device of the explosion-proof performance of the explosion-proof form of this equipment.The chief component of existing electrical apparatus for explosive atmospheres (anti-explosion cable connector) is clamp nut formula cable entry.Described clamp nut formula cable entry mainly comprises clamp nut, pressure ring, sealing ring and cross over pipe.Wherein sealing ring and pressure ring are arranged in cross over pipe, and pressure ring withstands sealing ring from a side, and clamp nut is sheathed on the outside of pressure ring.After the access cable, clamp nut is exerted pressure to pressure ring, and the further crush seal circle of the latter, make to produce radial expansion after the sealing ring pressurized, thereby reach the effect of sealing.
The loosening situation of cable, easily occur in the introducing hold down gag of this structure in actual use, once and occur looseningly, be easy to cause very serious consequence.For this reason, designed in the industry a kind of clamping structure of integral type broadening formation in the outside of introducing device, be made into integration with introducing device, horn mouth goes out to be provided with a fluting, be provided with a compressing tablet in fluting, by bolt and nut by cable to a bell-mouthed side compression with anti-loosening.But due to this structure be by cable to a bell-mouthed side compression, easily cause the loosening of back panel wiring, therefore be necessary further to be improved, to get rid of hidden danger.
The utility model content
The purpose of this utility model just is to improve existing cable and introduces the existing above-mentioned hidden danger of hold down gag, thereby provides a kind of novel cable to introduce hold down gag.
Cable of the present utility model is introduced hold down gag and is comprised clamp nut formula cable entry, also is provided with a split type detachable cable anti-drop device.
Described clamp nut formula cable entry comprises clamp nut, pressure ring, sealing ring and cross over pipe, and described sealing ring is arranged at the inboard of cross over pipe, and pressure ring is close to the sealing ring setting in the outside of sealing ring, and clamp nut is arranged at a side of cross over pipe lead-in cable.
Described cable shedding-proof apparatus comprises compression strip and ox horn formula retainer plate.Wherein, described ox horn formula retainer plate is secured by bolts on clamp nut, and described compression strip is a pair of, by screw bolt and nut, is fixed on ox horn formula retainer plate, the both sides, middle part of each compression strip are equipped with inside concave arc, for clamp and attached cable with anti-loosening.
Cable of the present utility model is introduced hold down gag, owing to having set up cable shedding-proof apparatus, can effectively prevent that in use procedure, loosening situation occurs cable, thereby promote fail safe; And a pair of compression strip the center of the position of cable being fixed in to cable aperture is set, internally cable connection does not impact; In addition, anti-drop device is split type detachable, conveniently according to client's requirement, makes trade-offs.

Embodiment
Below in conjunction with accompanying drawing, with specific embodiment, cable of the present utility model is introduced to hold down gag and be described in further detail.Should be understood that following examples are only for the utility model is described but not for limiting scope of the present utility model.
As shown in Figure 1, cable of the present utility model is introduced hold down gag except clamp nut formula cable entry 10, also is provided with a split type detachable cable anti-drop device 20.Wherein:
Described clamp nut formula cable entry 10 comprises clamp nut 11, pressure ring 12, sealing ring 13 and cross over pipe 14, described sealing ring 13 is arranged at the inboard of cross over pipe 14, pressure ring 12 is close to sealing ring 13 and is arranged in the outside of sealing ring 13, clamp nut 11 is arranged at a side of cross over pipe 14 lead-in cables.
Described cable shedding-proof apparatus 20 comprises ox horn formula retainer plate 21 and compression strip 22, described ox horn formula retainer plate is fixed on clamp nut 11 by four bolts 24, compression strip 22 is a pair of, both sides are provided with through hole 23, fixing by bolt 24 and nut 25, the both sides, middle part of each compression strip 22 are equipped with inside concave arc, to cooperatively interact, clamp and attached cable; And, a pair of compression strip 22 the center of the position of cable being fixed in to cable aperture is set, internally cable connection does not impact.
During use, cable is passed to ox horn formula retainer plate 21, clamp nut 11, pressure ring 12, sealing ring 13 and cross over pipe 14 successively.After the associated components installation, successively cross over pipe 14, sealing ring 13, pressure ring 12, clamp nut 11 are recovered, after clamp nut 11 fully compresses with cross over pipe 14, recover again ox horn formula retainer plate 21, ox horn formula retainer plate 21 is fixed on clamp nut 11, then according to the size of the outside diameter of cable, a pair of compression strip 22 forwards are installed or oppositely clamped cable, then with bolt 24 and nut 25 assemblies, compression strip 22 is arranged on ox horn formula retainer plate 21.
Cable of the present utility model is introduced hold down gag, owing to having set up cable shedding-proof apparatus, can effectively prevent that in use procedure, loosening situation occurs cable, thereby promote fail safe; And split type dismountable anti-drop device is convenient to be made trade-offs according to client's requirement.
