Abstract
The invention discloses a cable lead-in compression device. The cable lead-in compression device comprises a compression nut type cable lead-in device and is further provided with a split type detachable cable falling-off prevention device. The compression nut type cable lead-in device comprises a compression nut, a pressure ring, a seal ring and a closed tube. The seal ring is arranged on the inner side of the closed tube. The pressure ring is arranged on the outer side of the seal ring and closely attached to the seal ring. The compression nut is arranged on the side, where a cable is led in, of the closed tube. The cable falling-off prevention device comprises two wire pressing strips and an ox horn type fixing ring fixed to the compression nut through a bolt, and the two wire pressing strips are fixed to the ox horn type fixing ring through bolts and nuts and used for clamping and fixing the cable to prevent loosening. As the cable falling-off prevention device is additionally arranged, the situation that the cable loosens during use can be effectively prevented, and safety is improved.
Description
Technical field
The invention belongs to electrical apparatus for explosive atmospheres field, specifically, is 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 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 side, and clamp nut is sheathed on the outside of pressure ring.When after access cable, clamp nut is exerted pressure to pressure ring, and the further crush seal circle of the latter, produces radial expansion after making sealing ring pressurized, thus reach the effect of sealing.
, easily there is the situation that cable loosens in actual use, and once occur to loosen, be easy to cause very serious consequence in the introducing hold down gag of this structure.For this reason, devise 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 in case loosen.But due to this structure be by cable to a bell-mouthed side compression, easily cause back panel wiring loosen, be therefore necessary to be improved further, to get rid of hidden danger.
Summary of the invention
Object of the present invention is just to improve the above-mentioned hidden danger of existing cable introducing existing for hold down gag, thus provides a kind of novel cable to introduce hold down gag.
Cable of the present invention is introduced hold down gag and is comprised clamp nut formula cable entry, is also 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 inner side of cross over pipe, and pressure ring is close to sealing ring and is arranged in the outside of sealing ring, clamp nut is arranged at the 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, is fixed on ox horn formula retainer plate by screw bolt and nut, the both sides, middle part of each compression strip are equipped with inside concave arc, for clamping and attached cable with anti-loosening.
Hold down gag introduced by cable of the present invention, owing to having set up cable shedding-proof apparatus, effectively can prevent cable in use procedure from situation about loosening occurring, thus improve fail safe; And a pair compression strip the center position of cable being fixed on cable aperture is set, can not internally impact by cable connection; In addition, anti-drop device is detachably split type, conveniently makes trade-offs according to the requirement of client.

Embodiment
Below in conjunction with accompanying drawing, with specific embodiment, hold down gag is introduced to cable of the present invention and be described in further detail.Should be understood that following examples only for illustration of the present invention but not for limiting scope of the present invention.
As shown in Figure 1, cable of the present invention introduces hold down gag except clamp nut formula cable entry 10, is also 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 inner side of cross over pipe 14, pressure ring 12 is close to sealing ring 13 in the outside of sealing ring 13 and is arranged, and clamp nut 11 is arranged at the side of cross over pipe 14 lead-in cable.
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, both sides are provided with through hole 23, fixed by bolt 24 and nut 25, the both sides, middle part of each compression strip 22 are equipped with inside concave arc, with the clamping also attached cable that cooperatively interacts; Further, a pair compression strip 22 the center position of cable being fixed on cable aperture is set, can not internally impact by cable connection.
During use, by cable successively through ox horn formula retainer plate 21, clamp nut 11, pressure ring 12, sealing ring 13 and cross over pipe 14.After associated components installation, successively cross over pipe 14, sealing ring 13, pressure ring 12, clamp nut 11 are recovered, after clamp nut 11 and cross over pipe 14 fully compress, recover ox horn formula retainer plate 21 again, 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 compression strip 22 forward is installed or oppositely clamped cable, then with bolt 24 and nut 25 assembly, compression strip 22 is arranged on ox horn formula retainer plate 21.
Hold down gag introduced by cable of the present invention, owing to having set up cable shedding-proof apparatus, effectively can prevent cable in use procedure from situation about loosening occurring, thus improve fail safe; And split type dismountable anti-drop device conveniently makes trade-offs according to the requirement of client.
