Abstract
The utility model relates to a wire cable seal joint, which comprises a sealing nut, a shell and a seal rubber sleeve arranged in the shell. Wire cable through holes are arranged on the seal rubber sleeve; extrusion plates are arranged on the inner side and the outer side of the seal rubber sleeve inside the shell; the extrusion plate on the inner side props against the inner top edge of the inner wall of the shell; and the end of the extrusion plate on the outer side protrudes beyond the end face of the shell. Both extrusion plates are provided with wire through holes corresponding to the wire cable through holes of the seal rubber sleeve. The seal surfaces of the wire cable through holes of the seal rubber sleeve are seal tooth faces. The teeth of the seal tooth faces are all independent closed ring-shaped teeth. The wire cable seal joint uses the extrusion plates for extrusion so that the seal rubber sleeve is deformed and seals the wire cables; the extrusion plates are simple in structure and can be processed conveniently in batches; the material requirements are low, thus significantly reducing the product cost. In addition, a plurality of seal rings are formed between the seal tooth faces of the seal rubber sleeve and the wire cables; so the linearly contacted seal rings have better sealability than the entire seal faces.
Description
Technical field
The utility model relates to a kind of cable seal nipple.
Background technology
Existing cable seal nipple mainly is made of seal rubber sleeve in sealing nut, housing and the housing and elastic card claw, during use, pass the cable perforation of cable on sealing nut, housing and seal rubber sleeve, make the stressed contraction of elastic card claw by tightening sealing nut, elastic card claw compresses seal rubber sleeve again, realizes the sealing between cable and the seal nipple.Structure based on this sealing principle mainly contains two kinds at present: a kind of is that seal rubber sleeve is positioned at the elastic card claw bottom, make the elastic card claw local contraction compress seal rubber sleeve by tightening sealing nut, seal rubber sleeve packs tightly cable again, realizes the sealing between cable and the joint; Another kind is at seal rubber sleeve coenvelope elastic card claw and forms global facility, and these parts are packed in the housing, comes the partial compression elastic card claw by the lock sealing nut, and claw compresses seal rubber sleeve again, realizes the sealing between cable and the seal nipple.These two kinds of cable hermetically-sealed constructions are all finished sealing by elasticity of compression claw, claw seal form not only complex structure, manufacture difficulty is big, and must select the good material of elasticity for use, make material cost higher, however, through after repeatedly being tightly connected, still existing and cause the product seal failure because of elastomeric material is tired.
The utility model content
The purpose of this utility model provide a kind of simple in structure, be easy to processing and lower-cost cable seal nipple.
For achieving the above object, the utility model adopts following technical scheme: a kind of cable seal nipple, comprise the seal rubber sleeve in sealing nut, housing and the housing, has the cable via hole on the seal rubber sleeve, the inside and outside both sides of seal rubber sleeve are all by being provided with stripper plate in housing, the internal orifice that inboard stripper plate is resisted against inner walls is along last, and the end nipple of outside stripper plate is for the housing end face, and two stripper plates all have the cable-through hole corresponding to seal rubber sleeve cable via hole.
The sealing surfaces of seal rubber sleeve cable via hole is the sealing flank of tooth.
Each road teeth of the described sealing flank of tooth are independently closed ring teeth.
Cable is crossed on the hole surface has the cable bullport at the position at sealing flank of tooth two ends.
Described cable via hole is 1 to 6, and circumferentially; On the faying face of stripper plate and seal rubber sleeve, also be provided with only cyclone.The described cyclone of ending comprises that branch is located at cylinder and the jack on stripper plate and the seal rubber sleeve faying face, and cylinder fastens with jack and cooperates.
Described cylinder is located on the stripper plate, and the root of cylinder has reinforcing chamfer; Jack is located on the seal rubber sleeve, and jack advances Kong Chu and has the pilot angle adaptive with reinforcing chamfer.Described cylinder equates with jack quantity, is 2 to 6.
The utility model all is provided with stripper plate in the both sides of seal rubber sleeve, by tightening housing and sealing nut forms axial compression to stripper plate, by stripper plate pressure is passed to seal rubber sleeve again, impel seal rubber sleeve to produce strain, thereby seal with penetrating to form between the cable at housing.The utility model utilizes the stripper plate extruding, makes the seal rubber sleeve distortion realize sealing, and stripper plate is simple in structure, and batch machining is convenient, and is relatively low to material requirements, thereby greatly reduces product cost.In addition, what form between the sealing flank of tooth of seal rubber sleeve and cable is a plurality of sealing rings, and the integral sealing face of the sealing ring specific surface contact of a plurality of line contacts has more excellent sealing ability.Stop relatively rotating between stripper plate and seal rubber sleeve in the cyclone of ending that is provided with on stripper plate and the seal rubber sleeve faying face, prevent from cable is formed shear action, damage cable.

Embodiment
Fig. 1-cable seal nipple shown in Figure 6, comprise the seal rubber sleeve 3 in sealing nut 4, housing 1 and the housing, have circumferential three cable via holes 13 on the seal rubber sleeve 3, the two-end part that cable is crossed hole surface is a cable bullport 11,15, mid portion at the two ends bullport is the sealing flank of tooth 14 of cable via hole, each road teeth of the sealing flank of tooth are independently closed ring teeth, and the sealing flank of tooth can also adopt the helical tooth hermetically-sealed construction.In housing, the inside and outside both sides of seal rubber sleeve 3 are all by being provided with stripper plate 2, the internal orifice that inboard stripper plate is resisted against inner walls is along last, and the end nipple of outside stripper plate is for the end face of housing 1, and two stripper plates all have the cable-through hole 9 corresponding to seal rubber sleeve cable via hole.Among Fig. 1, the 5th, cable.
In order to make stripper plate cable-through hole 9 corresponding one by one with cable via hole 13 on the seal rubber sleeve, be convenient to assembling and install cable, on the faying face of stripper plate 2 and seal rubber sleeve 3, also be provided with only cyclone, in the present embodiment, ending cyclone is made up of three cylinders 6 and the corresponding jack 12 that is arranged on the seal rubber sleeve that are uniformly distributed along the circumference on stripper plate, cooperate by the fastening of cylinder 6, with two stripper plates and the seal rubber sleeve parts that form a whole, in the housing of can packing into easily with jack 12.In order to prevent cylinder 6 in use from root fracture, be provided with thick slightly reinforcing chamfer 8 at the root of cylinder, to improve the anti-fracture energy of cylinder, accordingly, be provided with the pilot angle 10 adaptive with reinforcing chamfer at the Kong Chu that advances of seal rubber sleeve jack 12.
