Abstract

The utility model relates to a cable electric wire connecting pipe, which comprises a middle connecting pipe and a wire connecting terminal pipe. The cable wire connecting pipe is characterized in that the inner side of the pipe wall is provided with a paste conducting accelerant layer and a hard granule layer. After inserted, the conducting wire core is surrounded by the pipe wall. After the connecting pipe is oppressed by a pressure tong, the conducting wire core is made to be fixed on the connecting pipe. The connecting pipe provided by the utility model enhances the connecting and conducting performance of cables and electric wires, is draw resistant and corrosion resistant, and is an ideal cable fitting.

Description

Cable wire connecting pipe

The utility model is to be used for the middle of sub-thread and strand wire cable to connect and the transition connection connecting tube and binding post pipe in the middle of comprising.

Connecting in the middle of the existing electric wire and the transition connection, is with connecting tube and binding post pipe.Compress through pressure clamp, reach the purpose that connects energising, crimping place contact-making surface is easy to generate oxide layer, cause the resistance increase and generate heat waste electric energy, the meeting that has generation spark, then cause and open circuit, in addition, connection place tensile strength weakness, through gravity and mechanical force, the connection place is prone to loosening, and above-mentioned reason all can make circuit cause that the power failure stopping production brings loss, finding out off position is to spend a large amount of man power and materials, is the difficult problem in the present line maintenance.

At above-mentioned shortcoming, what the utility model proposes can make the long-term energising of circuit good, reduces the cable and wire connection pipe fitting of unnecessary energy loss.

These cable and wire connection pipe fitting characteristics are: the tube wall inboard is provided with paste conduction promoter layer and hard granule layer, and the wire stylet of insertion is among paste conduction promoter layer and the encirclement of hard granule layer.Paste conduction promoter layer and hard granule layer are more preferably and are crossed as mixed layer in addition.

The utility model also mills the mark ditch one at 1/2 place of length in the middle connecting tube in above-mentioned connection pipe fitting, when inserting as two lead with reference to usefulness, preventing has influenced short-term head pull-off strength less because of one in lead inserts the insertion of many other ends, the connecting tube inwall is provided with paste conduction promoter layer and hard granule layer then reaches the good purpose of long-term energising with conductor compression jointing in the middle of the cable and wire, and the binding post pipe in the utility model also has similar advantage.

Accompanying drawing 1 is a cable and wire binding post tubular construction cutaway view,

Accompanying drawing 2 is a connecting tube structure cutaway view in the middle of the cable and wire.

Wherein, (1) tube wall, (2) paste conduction promoter layer, (3) hard granule layer, (4) wire stylet, (5) mark ditch.

As shown in the figure, system one mark ditch (5) is milled at tube wall in middle connecting tube (1) axial length 1/2 place, to conduct electricity promoter layer (2) and hard granule layer (3) by brushing in tube wall (1) inboard, the wire stylet (5) of peelling off insulating barrier is inserted different pipe fittings, with pressure clamp tube wall (1) is depressed several roads impression, at this moment conducting electricity promoter layer (2) and hard granule layer (3) is crushed between wire stylet (4) and tube wall (1) inboard, at the pressurized position, be extruded unnecessary conduction promoter of part and hard granule and enter not pressurized position, between tube wall (1) and wire stylet (4), be full of the mixed layer (2 that paste conduction promoter and hard granule are formed like this, 3), played the effect that air-isolation prevents oxidized reduction sheet resistance, conductive area is increased greatly have good conduction property, hard granule layer (3) is embedded into when pressurized between wire stylet (5) and the tube wall (1) and plays the pin effect, prevent the loosening of wire stylet (4), more on this paste conduction promoter market, for example the DJG-1 or the DG-1 of Fujian product electrically contact conductive paste or the like, and the hard granule then can be general quartz sand, boart boart or the like.

Claims

1, a kind of cable and wire connection pipe fitting is characterized in that tube wall (1) inboard is provided with paste conduction promoter layer (2) and hard granule layer (3), and the wire stylet of insertion (4) is among paste conduction promoter layer (2) and hard granule layer (3) encirclement.

2,, it is characterized in that paste conduction promoter layer (2) and hard granule layer (3) are crossed as mixed layer according to the described cable and wire connection pipe fitting of claim 1.

3,, it is characterized in that middle connecting tube tube wall (1) axial length 1/2 place of cable and wire is provided with mark ditch (5) according to claim 1 or 2 described cable and wire connection pipe fittings.
