Description
Technical field
The utility model relates to the jointing of cable, more specifically to a kind of energy-saving electric joint.
Background technology
In the binding post on the various electrical equipment of power industry, the product of use is relatively backward, a kind of tubular type joint that often uses at present, formed by aluminum pipe and connected copper connecting hole, during use, wire or cable are inserted in the aluminum pipe, with Crimping Pliers pressing aluminum pipe, and then wire is connected.Feel when the quality of quality of connection can only be with pressing, effective contact area of aluminum pipe crimping can not determine, jaw place pressure is larger, and remainder is unsettled, can cause vacation to connect the phenomenon of false kiss or virtual connection; Or because of the interlock of pressing mouthful module improper, can generate alundum (Al2O3) and cupric oxide oxide-film on copper aluminium joint surface, easily crack after the joint oxidation or rupture the electric conductivity extreme difference of these oxide-films, and chemical property is stable, be attached to for a long time the electric conductor surface, can increase contact resistance, the larger electric energy loss of contact resistance is higher, in the situation that electric current is slightly large, easily cause connection position heating, even cause joint fusing, bring great threat for electricity consumption for safety.
The utility model content
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, and a kind of energy-saving electric joint of simple in structure, good reliability is provided.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of energy-saving electric joint, formed by terminals, potted ends, fastening end, terminals and potted ends are integrated, terminals are provided with the wiring hole for fastening coupled cable, potted ends is a blind hole cylinder, be used for equipped cable, cylindrical outer wall is provided with one section screw thread that is used for connecting the fastening end, is provided with vertically many retraction slots around the potted ends hole wall; The fastening end is a sleeve, peripheral hardware one nut, sleeve lining are provided with one section internal thread, and internal thread is used for the fastening end is enclosed within potted ends, to be inserted in cable locking in the potted ends by screwing nut, be provided with the annular spring leaf for the jam-packed cable in the described potted ends.
In the above-mentioned energy-saving electric joint, be provided with vertically four retraction slots around the described potted ends hole wall.
In the above-mentioned energy-saving electric joint, the length of described potted ends is 15～20mm.
In the above-mentioned energy-saving electric joint, the length of described potted ends is 20mm.
In the above-mentioned energy-saving electric joint, the reach of described cylinder cylindrical setting is 10～15mm.
In the above-mentioned energy-saving electric joint, the reach of described cylinder cylindrical setting is 15mm.
Compared with prior art, the beneficial effects of the utility model:The utility model is simple in structure, by in the cylinder of potted ends, being provided for the annular spring leaf of jam-packed cable, change potted ends and reach, the cable head is packed into behind the annular spring leaf in the blind end, owing to being enclosed with annular spring leaf around cable the end of a thread, strengthened potted ends inwall and cable contact-making surface, made the inwall of potted ends contact closelyr with cable adapter; Reduced simultaneously the contact-making surface of the wire terminal of potted ends inner cable and air, reduced the oxidized possibility of cable adapter, thereby reduced contact resistance, prevented conductor joint heating, equipment has been used more safe and reliable.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the energy-saving electric joint of the present embodiment is that potted ends 2, the fastening end 3 of 20mm forms by terminals 1, length, and terminals 1 are integrated with potted ends 2, and terminals 1 are provided with wiring hole 4, are used for fastening coupled cable; Potted ends 2 is a blind hole cylinder, is used for equipped cable, and cylindrical cylindrical is provided with the screw thread 5 that a segment length is 15mm, is used for connecting fastening end 3, is provided with vertically four retraction slots 6 around potted ends 2 hole walls; Fastening end 3 is a sleeve, its end is nut 7, and one section internal thread 8 is arranged in the sleeve, and internal thread 8 is used for fastening end 3 is enclosed within potted ends 2, to be inserted in cable locking in the potted ends 2 by screwing nut 7, be provided with the annular spring leaf 9 for the jam-packed cable in the described potted ends 2.
The using method of the present embodiment is: the cable head is packed into behind the annular spring leaf 9 in the blind end 2, screw fastening end 3, the propelling of fastening end 3 makes the outer surface radial contraction on the blind end 2, owing to being enclosed with annular spring leaf 9 around cable the end of a thread, during outer surface radial contraction on the blind end 2, press strip 10 on the compression ring shape spring leaf 9 inwardly shrinks simultaneously, make press strip 10 contact closelyr with cable, when having avoided the outer surface radial contraction of blind end 2, the outer surface that cylinder is abutted against line end one side be subjected to fastening end 3 to screw compression stress too small, cause the radial contraction insufficient amplitude, and make the unsettled situation of cable socket part.Cable the end of a thread is subjected to the parcel of annular spring leaf 9 simultaneously, has reduced the contact-making surface of potted ends 2 inner cable wire terminals and air, has reduced the oxidized possibility of cable adapter, thereby has reduced contact resistance, prevents equipment heating, equipment is used more safe and reliable.The electrical connector that screw thread 5 length that the length of potted ends 2 and cylinder cylindrical arrange are more general is long, during rotation fastening end 3, can be more near the end (namely near terminals one side) to potted ends, outer surface radial contraction amplitude with assurance blind end 2 is more even, makes the inwall of potted ends contact closelyr with cable adapter.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
