Abstract
The present invention discloses an elbow-shaped plug connector for power cables, which has the advantages of reasonable structure, sealing combination and high reliability. The present invention comprises an elbow-shaped outer sleeve of a connector, a wire ear, a horizontal bolt and a fixing clamp, wherein the elbow-shaped outer sleeve of the connector is formed by the compression of an inner layer, a middle layer and an outer layer which are made of different silicon rubber materials; the upper part of the elbow-shaped outer sleeve presents an inner cone shape which is fixedly matched with an outer cone surface of a cannula of a switch cabinet, and the lower part presents a funnel shape of which the inner hole is matched with a cable; the surface of the elbow-shaped outer sleeve is connected to the ground by a connecting wire through an earth connection hole; the wire ear is arranged at the corner of the inner layer of the elbow-shaped outer sleeve, and the upper part of the wire ear is connected with the horizontal bolt by a screw thread; the elbow-shaped outer sleeve of the connector is provided with the fixing clamp which is connected with the cannula.
Description
Technical field:
The present invention relates to the electric cable accessories technical field used in the power cable engineering, refer 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 object of the invention 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, technical scheme provided by the invention is: include connector elbow overcoat, line ear, horizontal latch and geometrical clamp, this connector elbow overcoat by internal layer, middle level and skin the compacting of totally three layers of Different Silicon elastomeric material form; The top of connector 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 connector elbow overcoat appearance is used lead ground connection by ground hole; The line ear is located at the corner of connector 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 present invention 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 invention will be further described below in conjunction with accompanying drawing:
Accompanying drawing 1 is a structure cutaway view of the present invention;
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, this connector elbow overcoat 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 connector elbow overcoat is inner conical, and the male cone (strobilus masculinus) of the sleeve pipe of itself and switch cubicle cooperates fixing, and connector 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 connector 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 invention only, is not to limit practical range of the present invention with this, so the equivalence that all shapes according to the present invention, structure and principle are done changes, all should be covered by in protection scope of the present invention.
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: this connector elbow overcoat by internal layer (1), middle level (2) and outer (3) totally three layers of Different Silicon elastomeric materials compacting form; The top (4) of connector elbow overcoat 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 connector elbow overcoat appearance is used lead ground connection by ground hole; Line ear (7) is located at the corner of connector 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.
