Description
Technical field
The utility model relates to a kind of quick coupling, belongs to power cable and electric equipment connection area.
Background technology
In binding post on the various electrical equipment of current power industry, a kind of tubular type joint of frequent use, during use, by cable Inserting Tube, with hydraulic tongs pressing body, and then cable is connected, and the quality of quality of connection can only rely on feel during pressing to judge, effective contact area of body crimping be can not determine, jaw place pressure is larger, remainder is unsettled, and vacation can be caused to connect the phenomenon of false kiss or virtual connection; Or because of the occlusion of jaw improper, alundum (Al2O3) and cupric oxide oxide-film can be generated on joint surface, easily crack after joint oxidation or rupture, the electric conductivity extreme difference of these oxide-films, and chemical property is stablized, be attached to electric conductor surface for a long time, can increase contact resistance, the larger electric energy loss of contact resistance is higher, when electric current is slightly large, easily cause connection position heating, even cause joint to fuse, bring great threat for electricity consumption to safety.
To this, a kind of energy-saving fast fastening joint is disclosed in patent documentation CN203423274U, comprise joint body, it comprises the connecting plate being provided with through hole and the wire barrel being provided with tube chamber be connected with described connecting plate one end, the tube wall of described wire barrel is provided with at least two retraction slots arranged vertically, and the outer wall of described wire barrel is provided with external screw thread and outer hierarchic structure; Have the lock sleeve of tube chamber, its inwall is provided with the internal thread that is connected with described external screw thread and hierarchic structure in locking with described outer hierarchic structure.This fast fastening joint in use, the end of cable is inserted in the tube chamber of wire barrel, force wire barrel to shrink by tightening lock sleeve and compress cable, and then completing the connection of joint and cable, the lock-on connection of this structure when mounted, adopt common wrench jointing body and lock sleeve, hydraulic tongs need not be used to crimp, easy for installation, and product can reuse, energy-conserving and environment-protective, have good result of use compared with tubular type joint.But the joint also Shortcomings in this patent documentation: the inwall of (1) wire barrel openend is right angle, after lock sleeve screws, the mouth of pipe place of wire barrel forms taper, this just causes only wire barrel mouth of pipe place inside corner and conductive cable contacts, little with conductive cable contacts face, contact resistance is large, when passing through by big current, there is potential safety hazard, Long-Time Service even can affect normal power supply; (2) joint body adopts a bar to process, and is adding man-hour, one side pressure is being put down, other end end face bores wiring hole, so just causing manufacturing procedure more, and needs to purchase multiple stage process equipment, and production cost is higher.
Utility model content
To this, the purpose of this utility model is to provide a kind of large with conductive cable contacts face, the quick coupling of good electric property.
The technical scheme realizing the utility model object is:
A kind of quick coupling, comprise joint body and the lock sleeve supporting with described joint body, described joint body one end is terminal block, and the other end is wire barrel; The tube wall of described wire barrel is provided with the retraction slot arranged vertically, and the outer wall of described wire barrel is provided with external screw thread and outer hierarchic structure; The inwall of described lock sleeve is provided with the internal thread that is connected with described external screw thread and hierarchic structure in locking with described outer hierarchic structure; The inwall at described wire barrel mouth of pipe place is provided with the conical contact face be subject to the cable close contact inserted in wire barrel after described lock sleeve squeezing action.
In technique scheme, described joint body is that one end of a pipe is formed through crimping.
In technique scheme, the sidewall of described wire barrel is provided with screw, is provided with line pressing bolt in described screw.
In technique scheme, the tube wall of described wire barrel is also provided with spilled water hole.
The utility model has positive effect:
(1) in quick coupling of the present utility model, the inwall at described wire barrel mouth of pipe place arranges conical contact face, product in use, tighten described lock sleeve, described lock sleeve forces wire barrel to shrink and makes conical contact face and cable close contact, and increase effectively the contact area of joint body and cable, the electric property of joint is better, can pass through by bearing great current, there is good result of use.
(2) in quick coupling of the present utility model, adopt pipe machine-shaping, adding man-hour by the described terminal block of one end of pipe pressing formation, pipe other end tube chamber is as wiring hole, thus without the need to processing wiring hole in addition, decrease manufacturing procedure, and then decrease process equipment (punch device), reduce production cost.
(3) in quick coupling of the present utility model, the sidewall of described wire barrel is provided with screw, is provided with line pressing bolt in described screw; By adopting this structure, tightening described line pressing bolt and the cable inserted in wire barrel pipe is pressed on lumen wall, thus further increasing the contact-making surface of joint body and cable, reduce further contact resistance.
(4) in quick coupling of the present utility model, by arranging spilled water hole on the tube wall of wire barrel, the rainwater entered in wire barrel can be discharged in time.
