The invention achieves the advantages that: effective seal is arranged between the wire passing device and the shell wall, between the different wires, thereby, the anti-seepage reliability is high, wire passing is convenient, the structure is simple, and the mounting and demounting are easy.
Description
Technical field
The present invention relates to a kind of electrical wire wall-passing device, be used for the electric wire of locking device electric equipment is passed the shell wall of locking device.
Background technology
Some locking devices for example all have the cable of electric equipment to pick out in the bearing housing in the large hydraulic machinery equipment, the gear box usually, but the needs of component lubrications such as bearing, gear during owing to equipment operation, make fluid splash in the whole case chamber, the tiny oil droplets that also can form aerosolization simultaneously spreads in the case chamber, make common threading apparatus be difficult to reach sealing effectiveness, fluid can be from the slit of tank wall perforation or is seen that along line the gap oozes out, and pollutes even causes potential safety hazard.And although can reach the effect of sealing antiseepage, there is complex structure in the threading apparatus of some aerospace seal plug forms, and interior outer lead needs disjunction, wiring inconvenience, and the dismounting difficulty, the manufacturing cost height, defective such as cost an arm and a leg, thereby also be difficult to be applied.
Summary of the invention
Purpose of the present invention is the shortcoming that overcomes existing threading apparatus, and a kind of positiver sealing barrier performance that has is provided, and is simple in structure, the electrical wire wall-passing device of easy installation and removal.
Technical solution of the present invention is as follows:
A kind of electrical wire wall-passing device comprises and wears wall guide pin bushing, wire passing plug, gland, check ring; The described wall guide pin bushing of wearing is the hollow bolt structure, has bolt head, polished rod section, spiro rod section, and the diameter of polished rod section, length and shell wall hole are suitable, and spiro rod section has adaptive nut, and hollow bolt is locked in the shell wall hole; This mating surface of wearing wall guide pin bushing and shell wall is provided with seal; The endoporus of wearing the wall guide pin bushing is the aperture of a plurality of dispersed placement, arranges a wire passing plug in each aperture, and electric wire is in wire passing plug; Described wire passing plug is a conical tube structure, and its outer surface is the awl cylinder; Described gland is a perforated plate construction, and the quantity in hole, position correspondence are worn the aperture of wall guide pin bushing, and the aperture is less than the diameter at butt end of wire passing plug; Described check ring is between nut, gland, and gland is pushed down the big end surface of wire passing plug, with the wire passing plug swelling in the aperture of wearing the wall guide pin bushing.
Described seal is an O-ring seals, is located at shell wall and wears axial mating surface and/or radial fit face between the wall guide pin bushing.
Described seal is a T shape sealing shroud.
The described wall guide pin bushing of wearing is an external conical sleeve, and described T shape sealing shroud is an inner conical drogue, the two tapering unanimity.
Described T shape sealing shroud is polytetrafluoroethylene cover or rubber sleeve.
Described wire passing plug is made with rubber or plastics.
The invention has the beneficial effects as follows: between threading apparatus and the shell wall, all effectively sealed between each bar electric wire, antiseepage reliability height, threading is convenient, and is simple in structure, easy installation and removal.
Below in conjunction with the drawings and the specific embodiments in detail the present invention is described in detail.

Embodiment
Embodiment one
Referring to Fig. 1, Fig. 2: this electrical wire wall-passing device comprises wears wall guide pin bushing 1, wire passing plug 4, gland 5, check ring 6.
Wearing wall guide pin bushing 1 is the hollow bolt structure, has bolt head, polished rod section, spiro rod section, and the diameter of polished rod section, length and shell wall hole are suitable, and spiro rod section has adaptive nut 3, and hollow bolt is locked in the shell wall hole.
The mating surface of wearing wall guide pin bushing 1 and shell wall 7 is provided with O-ring seals 2, is located at shell wall 7 and the axial mating surface of wearing between the wall guide pin bushing 1, also can be located at the radial fit face, also can spool, the radial fit face all establishes.
The endoporus of wearing wall guide pin bushing 1 is the aperture of a plurality of dispersed placement, arranges a wire passing plug 4 in each aperture, and electric wire is in wire passing plug 4; These wire passing plug 4 usefulness rubber or plastics are made, and are conical tube structure, and its outer surface is the awl cylinder.
Check ring 6 is U-shaped broken rings, and between nut 3, gland 5, gland 5 is pushed down the big end surface of wire passing plug 4, jack panel 3, just with wire passing plug 4 swellings in the aperture of wearing wall guide pin bushing 1, check ring 6 has locking effect, nut 3 is difficult for loosening, seals reliable and stable.
Said structure has solved effectively to be worn between wall guide pin bushing 1 and the shell wall 7 and the sealing problem between each electric wire, good seepage-proof property, and also simple in structure, threading is convenient, needn't cut off electric wire.
The using method of this electrical wire wall-passing device has following two kinds of threading modes:
Electric wire from outside pierce in the shell wall 7.
Earlier institute's live wire is passed nut 3, pass each hole of gland 5 more respectively, wire passing plug 4 of cover on each wire, pass O-ring seals 2 more jointly, pass the hole of shell wall 7 then, pass each hole of wall guide pin bushing 1 more respectively, then that each part is in place one by one, loading spring back-up ring 6 is jack panel 3.
2. electric wire passes outside the shell wall 7 from interior.
The threading order is opposite with said process.
