Abstract

The utility model relates to a cable connection joint of electrical equipment, particularly relates to a universal energy-saving electrical joint. The universal energy-saving electrical joint comprises a joint terminal, a joint encapsulation end and a joint fastening end. The terminal is integrated with the encapsulating end; a round blind hole is arranged on the terminal; a fastening bolt and a bolt hole are arranged on the outer side of the terminal to fasten the cable connected therewith. The encapsulation end is a blind-hole cylinder used to assemble the cable; a segment of thread and a segment of conical surface are arranged on the external circle to connect the fastening end; four contraction grooves are arranged on the hole-wall periphery of the encapsulation end in the axial direction; the fastening end is a cylinder, and a cap nut is arranged thereon; a segment of female thread and a segment of inner taper face are arranged in the cylinder used to coat the fastening end on the encapsulation end; and a fastening screw cap is used to fasten the cable inserted in the encapsulation end. The universal energy-saving electrical joint has the advantages of energy saving and nonferrous metal resource saving properties, small size, light weight, low cost, wearing well, safe and reliable performances, little resistance, low temperature rise, strong withdrawal force, and the like.

Description

The general-purpose energy-saving electrical connector

Technical field

The utility model relates to the joint that the electric equipment cable connects, and refers in particular to a kind of general-purpose energy-saving electrical connector.

Background technology

At present, international and domestic in transformer being installed and cable is connected, still adopt the device clamp of old-fashioned clamping plate type, because this product of continuing to use decades is made with aluminium, and transformer conducting bar belongs to the making of electrician's level fine copper, two kinds of different materials link to each other and are easy to oxidation, produce high temperature and burn out transformer conducting bar, to the economic loss that enterprise causes device damage and the repairing that has a power failure brings, particularly in midsummer and severe winter of peak times of power consumption, the Vintage Product device clamp is usually given and is ensured that power supply makes troubles, and causes under the adverse circumstances of being everlasting for the electrical network workman and rushes to repair transformer conducting bar.

Summary of the invention

The purpose of this utility model is improved, is innovated at shortcoming that exists in the background technology and problem, provides a kind of simple in structure, and cost is low, the general-purpose energy-saving electrical connector of dependable performance.

The technical solution of the utility model is: construct a kind of general-purpose energy-saving electrical connector of being made up of joint terminals, joint potted ends, joint fastening end, be characterized in that terminals and potted ends are one, terminals are provided with circle blind hole in, the terminals outside is provided with a fastening bolt and a screw, is used for fastening coupled cable; Potted ends is a blind hole cylinder, is used for equipped cable, and cylindrical cylindrical is provided with one section screw thread and one section conical surface, is used to connect the fastening end, is provided with four retraction slots around the potted ends hole wall vertically; The fastening end is a sleeve, and peripheral hardware one nut has one section internal thread and one section inner conical surface in the sleeve, is used for the fastening end is enclosed within potted ends, will be inserted in cable locking in the potted ends by screwing nut.

The utlity model has energy-saving and cost-reducingly, save national nonferrous metal resource, volume is little, in light weight, cost is low, durable in use, safe and reliable, advantage such as resistance is little, temperature rise is low, and withdrawal force is big.China is the country of many natural calamities such as a typhoon, flood, mud-rock flow, ice damage, to sudden natural calamity, we must accomplish to recover supply of electric power rapidly after the calamity, this general-purpose energy-saving electrical connector has been arranged, because little, the lightweight characteristics of volume, be easy to carry, in the process of speedily carrying out rescue work, only need a spanner just can finish electric line and connect very fast recovery supply of electric power, have the huge effect of immeasurable economic benefit and stable society.Its resistance is ten sixths of traditional clamping plate type device clamp, and that the joint withdrawal force is better than its twice is many, and the joint temperature rise has only 1/7th of clamping plate type equipment folder, and the ability that whole joint bears natural calamity is better than old-fashioned clamping plate type device clamp greatly.The utility model adopts electrician's level fine copper refining, the top layer is coated with high in technological content rare metal, has very strong resistance to corrosion, the utility model adopts spiral, the comprehensive contact of 360 degree, surface contacted resistance is little, under the nominal current conditions operation temperature rise low, easy to use, maintainable strong, reliability height, characteristics such as highly versatile, be common to copper, aluminium cable and copper, aluminium joint is connected, need not select corresponding joint and cable, both guarantee the operation of equipment long-term safety, play positive role for stable society again.The utlity model has high in technological contently, the characteristics of outward appearance U.S. are arranged again, transforming advantage and the economic benefit that electric line has fully shown it in installing.

Embodiment

By Fig. 1 to 3 as can be known, the utility model is made up of joint terminals 1, joint potted ends 2, joint fastening end 3, its characteristics are that terminals 1 and potted ends 2 are one, terminals 1 are provided with circle blind hole in, terminals 1 outside is provided with a fastening bolt 11 and a screw 12, is used for fastening coupled cable; Potted ends 2 is a blind hole cylinder, is used for equipped cable, and cylindrical cylindrical is provided with one section screw thread 21 and one section conical surface 22, is used to connect fastening end 3, is provided with four retraction slots 23 around potted ends 2 hole walls vertically; Fastening end 3 is a sleeve, and peripheral hardware one nut 33 has one section internal thread 31 and one section inner conical surface 32 in the sleeve, is used for fastening end 3 is enclosed within potted ends 2, will be inserted in cable locking in the potted ends 2 by screwing nut.

Terminals 1 profile described in the utility model is the hexagonal prism body.The nut 33 of described fastening end 3 is located at the termination.

Operation principle of the present utility model and using method: at first the rubber of cable end is pruned, make cable metal partly exposed outside, then the joint fastening end is enclosed within on the cable, allow the fastening end nut preceding, cable end is injected in the joint potted ends again, potted ends is pushed in the fastening end, make the internal thread of fastening end connect the external screw thread of going up potted ends, be stuck in spanner on the nut of fastening end and screw nut, make the conical surface on the inwall of fastening end stick the male cone (strobilus masculinus) of potted ends, because the propelling of the conical surface makes the outer surface radial contraction on the potted ends, until four retraction slots are closed up, can reach the requirement of fastening cable by designing requirement before retraction slot closes up.
