Abstract
The utility model discloses a cable conductor connecting pipe, comprising a pipe body, wherein the pipe body comprises a left conical pipe with the left portion thin and the right portion thick, a middle cylindrical pipe and a right conical pipe with the right portion thin and the left portion thick, inside the middle cylindrical pipe there is provided a conductive solid block, the left cylindrical pipe and the right cylindrical pipe are respectively and axially provided with a gap, the outer circumferences of the left and right conical pipes are connected with a left fastening nut and a right fastening nut respectively through screw threads, the inner wall of the pipe body and two end faces of the conductive solid block are respectively provided with a conductive composite paste layer. The cable conductor connecting pipe is reasonable in design, simple in structure, convenient and fast in operation, large in current carrying sectional area and not easy in heat generation at the joints, thereby fully reducing the on-site construction operations and being very convenient and practical in construction first-aid repair.
Description
Technical field
The utility model belongs to power industry crimping line technology field, particularly a kind of cable conductor tube connector.
Background technology
In electrical production; Cabling or maintenance cable need be with tube connector with two cable buttings, and the internal diameter of the cable conductor tube connector that uses at present leads directly to; Two cable conductors insert in the tube connector relatively, connect with the pressing mold cash pledge at the two ends of tube connector.In actual use, through-type tube connector need use gauze to polish off the inside pipe wall oxide-film when crimping, and the pipe outer wall does not have crimping direction and crimping point mark; The conductor joint is difficult for confirming; Flatten easily during crimping, need measure aluminium hydraulic pressed connecting pipe inwall length during exploitation cable external insulation, construction is inconvenient; The conductor joint is gapped, and during energising, electric current only passes through the crimping tube wall, and the current-carrying cross section is less, when having the joint heating accident through big electric current duration.
The utility model content
The utility model provides a kind of cable conductor to be easy to crimping, big, the difficult cable conductor tube connector that generates heat in joint of current-carrying sectional area in order to solve weak point of the prior art.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: the cable conductor tube connector; Comprise body, said body is made up of the thin right thick left conical tube in a left side, the thick right conical tube of a middle cylindrical tube and a right thin left side, is provided with the conduction solid slug in the middle cylindrical tube; A left side conical tube and right conical tube all axially offer the gap, left conical tube and right conical tube excircle be threaded respectively left clamp nut and right clamp nut.
Said inboard wall of tube body is provided with conduction compound layer with conduction solid slug both ends of the surface.
Adopt technique scheme; In the process of crimping cable conductor; The conduction solid slug possesses supporting role and has guaranteed that on the one hand the shape that connects does not change; With tight contact of cable conductor termination, both sides, increase orifice size when the axial restraint of solid slug of conducting electricity has on the other hand guaranteed crimping, reduced heating accident; After in two cable conductors are inserted into left conical tube and right conical tube respectively; Tighten left clamp nut and right clamp nut; The gap smaller of axially offering on left side conical tube and the right conical tube, thus left conical tube is fully contacted with two cable conductors with right conical tube inwall.Conduction compound layer further strengthens the electric conductivity of this tube connector, makes contact resistance reduce, and reduces heating accident.The utility model is reasonable in design, simple in structure, convenient to operation, and the current-carrying sectional area is big, and the joint is difficult for heating, fully reduces on-site construction processes, and the construction repairing is very convenient, practical.

Embodiment
As shown in Figure 1; The cable conductor tube connector of the utility model; Comprise by the thin right thick left conical tube 1 in a left side, the body that the thick right conical tube 3 of a middle cylindrical tube 2 and a right thin left side is formed; In be provided with conduction solid slug 4 in the cylindrical tube 2, left conical tube 1 axially offers gap 5 and gap 6 respectively with right conical tube 3, left conical tube 1 and right conical tube 3 excircles be threaded respectively left clamp nut 7 and right clamp nut 8.Inboard wall of tube body is provided with conduction compound layer 9 with conduction solid slug 4 both ends of the surface.
When work is used; In the process of crimping cable conductor; Conduction solid slug 4 possesses supporting role and has guaranteed that on the one hand the shape that connects does not change; With tight contact of cable conductor termination, both sides, increase orifice size when the axial restraint of solid slug 4 of conducting electricity has on the other hand guaranteed crimping, reduced heating accident; After in two cable conductors are inserted into left conical tube 1 and right conical tube 3 respectively; Tighten left clamp nut 7 and right clamp nut 8; The gap of axially offering on gap of axially offering on the conical tube 1 of a left side 5 and the right conical tube 36 diminishes, thereby left conical tube 1 is fully contacted with two cable conductors with right conical tube 3 inwalls.Conduction compound layer 9 further strengthens the electric conductivity of this tube connector, makes contact resistance reduce, and reduces heating accident.
