Abstract
The utility model discloses an elbow-shape pluggable connector of power cable having reasonable structure, sealing conbination and high reliability, which includes a connector elbow-shape coat, a line ear, an across bolt and a fixing nip. The elbow-shape coat of the connector is pressed with an inner layer, a middle layer and an outer layer made of silicone rubber material; the upper part of the elbow-shape coat is of inner cone shape, matching with and fixed with the outer cone surface of the sleeve for the switchboard, while having a choanoid lower part, with the inner hole matching with the cable. The surface of the elbow-shape coat is earthed by the lead through the earthing hole; the line ear is arranged at the corner of the elbow-shape coat lining, with the upper part connected to the across bolt by the whorl; also a fixing nip is arranged on the connector elbow-shape coat connecting with the sleeve.
Description
Technical field:
The utility model relates to the electric cable accessories technical field of using in the power cable engineering, refers in particular to a kind of elbow plug connector for power cables.
Background technology:
Prior art similar straight plug connector (hereinafter to be referred as connector), be to add a layer thickness by two layers of silastic material to make less than 1 millimeter appearance sprayed on material.Because sprayed on material is very thin, general thickness is less than 0.5mm, and its adhesive force reduces in time, anti-soil is not dirty, and the surface easily comes off, and easily makes the plug surface charging operation, one can not guarantee electrician's handling safety, and its two plug surfaces charging operation generates heat easily, burns cable and power equipment.On its internal structure the stress cone element is arranged simultaneously, the manufacturing process trouble.
Summary of the invention:
The utility model purpose is to overcome the deficiencies in the prior art, and a kind of rational in infrastructure, combination seal, elbow plug connector for power cables that reliability is high are provided.
For achieving the above object, the technical scheme that the utility model provides is: include connector elbow overcoat, line ear, horizontal latch and geometrical clamp, the elbow overcoat of this connector by internal layer, middle level and skin the compacting of totally three layers of Different Silicon elastomeric material form; The top of elbow overcoat is inner conical, and the male cone (strobilus masculinus) of the sleeve pipe of itself and switch cubicle cooperates fixing, and the bottom is an infundibulate, and its endoporus and cable cooperate, and elbow overcoat appearance is used lead ground connection by ground hole; The line ear is located at the corner of elbow overcoat internal layer, and line ear top is with being threaded horizontal latch: the connector elbow puts outward and also is provided with the geometrical clamp that is connected with sleeve pipe.
The utility model can reach beneficial effect rational in infrastructure, that each layer combination is tight, easy for installation, reliability is high by above technical scheme.
Description of drawings:
The utility model is described in further detail below in conjunction with accompanying drawing:
Accompanying drawing 1 is the utility model structure cutaway view;
Embodiment:
See shown in the accompanying drawing 1, present embodiment mainly is made of connector elbow overcoat, line ear 7, nut 8 and retainer ring, the elbow overcoat of this connector is by internal layer 1, middle level 2 and outer 3 totally three layers, it is the mould inside at HTHP, adds different silastic materials and makes, and each layer combination is tight, particularly outer 3 thickness are 3mm, can tolerate high filthy environment, can not come off, the reliability height.Shielding action is played at its internal layer 1 butt joint latch position, sleeve pipe interface position; The sealed insulation effect is played at 2 pairs of electrification in high voltage positions, middle level.Its skin 3 has shielded the high voltage electric field in middle level 2 by after the ground connection ear ground connection, and its whole appearance presents electronegative potential, and people's hand can touch and not have the electric sensation of fiber crops, guarantees electrician's handling safety, makes the plug appearance be difficult for generating heat the minimizing accident simultaneously.The funnel shaped of its outer bottom 5, its endoporus 6 and cable cooperate, and possess the effect that stress is dredged simultaneously, make that the electric field of cable incision position is even, guarantee the long-term safety operation of power cable.Omit the trouble of destressing awl element.The top 4 of elbow overcoat is inner conical, and the male cone (strobilus masculinus) of the sleeve pipe of itself and switch cubicle cooperates fixing, and elbow overcoat appearance is used lead ground connection by ground hole, guarantees outer field ground protection effect.Line ear 7 is located at the corner of elbow overcoat internal layer 1, line ear top is with the horizontal latch 8 that is threaded: the connector elbow puts outward and also is provided with the geometrical clamp that is connected with sleeve pipe, and the screw rod of geometrical clamp is fixed on the elbow plug by steel wire hook and pressing plate on the sleeve pipe of switch cubicle (scheming not shown).
The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection range of the present utility model.
Claims (2)
1, elbow plug connector for power cables, include connector elbow overcoat, line ear (7), horizontal latch (8) and geometrical clamp, it is characterized in that: the elbow overcoat of this connector by internal layer (1), middle level (2) and outer (3) totally three layers of Different Silicon elastomeric materials compacting form; The top of elbow overcoat (4) is inner conical, and the male cone (strobilus masculinus) of the sleeve pipe of itself and switch cubicle cooperates fixing, and bottom (5) be infundibulate, its endoporus (6) and cable cooperation, and elbow overcoat appearance is used lead ground connection by ground hole; Line ear (7) is located at the corner of elbow overcoat internal layer, and line ear top is with being threaded horizontal latch (8): the connector elbow puts outward and also is provided with the geometrical clamp that is connected with sleeve pipe.
2, elbow plug connector for power cables according to claim 1 is characterized in that: the thickness of the skin (3) of connector elbow overcoat is 2～4mm.
