Abstract
The utility model relates to a cable fitting, particularly an intermediate joint of cables. The utility model mainly solves the defects of complex production, poor elasticity, unreliable sealing insulating, etc. of the intermediate joint of a cable used in the prior art. The technical feature is that a joint is composed of an elastomeric insulating protective tube and a semiconductive tube overlapped and penetrated together. The earth line of the joint is composed of a clasp and a boding conductor. The utility model has the advantages of small size, easy and convenient production, and favorable performance of elasticity and seal. The utility model can be widely used for intermediate joints of twisted polyethylene cables under 1KW.
Description
The utility model relates to a kind of cable fitting, particularly a kind of cable intermediate joint.
The cable intermediate joint that prior art is used, all generally adopt hot shortness's electric cable accessories, be about to the electric cable accessories string and be contained on the cable of stripping, after heat shrink, the cable that disconnects is fused, and cable joint place hardness height, poor, the processed complex of bending property that prior art connects are particularly because heating is uneven, easily cause localized burn, cause sealing property to descend, and influence insulation level, prior art results in hand cramps to execute-in-place simultaneously.
The purpose of this utility model is design a kind of joint elastic and good seal performance, easy to make, quick, cable joint that size is little, to overcome the deficiencies in the prior art.
The purpose of this utility model is to realize like this; cable intermediate joint is made up of tube connector, insulation protection tube, semiconductive pipe, ground wire and external protection etc.; insulation protection tube is that double-layer overlapping installs structure; ground wire is made up of snap ring that compresses by bolt and bonding conductor; snap ring is fixed on that bonding conductor is connected with two snap rings on the ground wire of cable two ends; the semiconductive pipe is double-deck bridging arrangement, is provided with protective layer at the outermost layer of cable intermediate joint.
Below in conjunction with accompanying drawing the utility model is described in detail.
Accompanying drawing 1 is the utility model schematic diagram.
Accompanying drawing 2 is Figure 1B-B view.
Accompanying drawing 3 is Fig. 2 A-A view.
Referring to accompanying drawing; after the cable two joint strippings that will dock; in order interior semiconductive pipe 8, insulation protection tube 1, semiconductive pipe 2 and copper mesh 10 are installed on cable two joints in advance; with tube connector 7 with the cable core after the stripping 9; after fixedly connected; interior semiconductive pipe 8, insulation protection tube 1, semiconductive pipe 2 and the copper mesh 10 that will install in advance again returns to the centre position of cable intermediate joint, adds filler, is surrounded by elastic mechanical protective layer 5 at the cable intermediate joint outermost layer.On the ground wire at the cable two ends of docking, be fixed with two snap rings 3 and the bonding conductor 4 that compress by bolt, by snap ring 3, bonding conductor 4 the cable two ends ground wire of butt joint is communicated with, constitute the cable intermediate joint ground wire.
The utility model except that tube connector 7 adopts be rigidly connected, all the other all adopt elastomeric material, the utlity model has good springiness, sealing property is reliable, and it is simple in structure, field fabrication is convenient, and volume is little, and processing dimension is short, thoroughly solve hot shortness's cable intermediate joint, bendability is poor, makes complexity, poor sealing, shortcomings such as insulation level is low are specially adapted to the following twisted polyethylene cable transition joint of 10kw and use.
