Abstract
The utility model relates to a jointing clamp with the anti-wire breaking protection function, thereby solving a problem of frequent wire breaking of the connecting portion of the lead and the existing jointing clamp in daily use. The provided jointing clamp comprises a left metal jointing clamp body and a right metal jointing clamp body; and the left clamp body and the right clamp body are coupled by a rotating shaft. A torsional spring is installed at the rotating shaft; and the two extending ends of the torsional spring respectively exert forces on the inner sides of the left clamp body and the right clamp body. A left insulated clamp sleeve is sleeved at the lower end of the left clamp body; and a right insulated clamp sleeve is sleeved at the lower end of the right clamp body. The tail end of a lead passes through the lower end of the right insulated clamp sleeve, winds around the upper end of the torsional spring, extends out of the lower end of the left insulated clamp sleeve, passes through the lower end of the right insulated clamp sleeve again, goes around into the left clamp body from beneath the torsional spring, and then is welded and fixed with the inner wall of the left clamp body.
Description
Technical field
The utility model relates to a kind of binding clip that is electrically connected use, more specifically, relates to the binding clip of a kind of electrical test instrument wiring.
Background technology
In electric power overhaul experiment work, often need to use various specific battery of tests instruments to carry out various detection tests to power equipment, often be designed to the matching used various wires that are connected of test apparatus that one end is connected with test apparatus, the other end is connected with equipment under test.The one end being connected with equipment under test, adopts the binding clip of crocodile mouth structure conventionally, seems in actual use very convenient.But wire frequently ruptures with the position that the binding clip of crocodile mouth structure is connected, become a common fault of such test connection.
In use procedure, often appearance directly draws wire to draw the bad use habits such as binding clip; Binding clip is clipped in the eminence of equipment and is connected to the distance of test apparatus longer, and wire deadweight is larger; What in addition, binding clip fell down is also not little to the acting force of wire interconnecting piece position in a flash; These all cause wire and binding clip junction stressed larger, thereby also just than being easier to cause broken string.
For example, when the lightning arrester block property current tester device often using in electrical test is tested arrester resistance current, binding clip is fixed on the higher position of lightning arrester, and distance test (DT) instrument is also far away, just frequently there is the situation of wire and binding clip connecting portion broken string in this type of binding clip.
Same situation also occurs in other similar occasions.
Given this, be necessary to provide a kind of binding clip of breaking line preventive, can overcome the disadvantage of avoiding wire and the frequent broken string of binding clip in routine use.
Summary of the invention
(1) problem that will solve
The purpose of this utility model is to solve the problem of avoiding wire and the frequent broken string of binding clip in existing binding clip routine use.
(2) technical scheme
For addressing the above problem, the utility model proposes a kind of breaking line preventive binding clip, the binding clip left clip body, the right clip body that comprise metal, left and right clip body is coupling by rotating shaft, torque spring is housed in rotating shaft, two external parts of torque spring act on respectively the inner side of left and right clip body, and left clip body lower end cover has left insulating jacket, and the lower end cover of right clip body has right insulating jacket; The end that it is characterized in that wire first through the lower end of right insulating jacket, walk around the upper end of torque spring, from the lower end of left insulating jacket, pass again, again through the lower end of right insulating jacket, be then welded and fixed in left clip body and with the inwall of left clip body below torque spring.
As preferably, the wire that described wire is having insulation sheath.
(3) beneficial effect
Breaking line preventive binding clip of the present utility model, wire is not to be just welded and fixed with metal clip body after directly penetrating insulating jacket, but adopt wire through after insulating jacket, walk around torque spring, from opposite side insulating jacket pass, again penetrate this side insulating jacket, from torque spring below again through in opposite side insulating jacket, wire end is welded and fixed with folder body inner side.Adopt such structure, wire, through the Elastic Contact between repeatedly coiling, particularly wire and insulating jacket, can effectively cushion the tensile force that wire external part is subject to, the problem that also just can avoid binding clip and wire interconnecting piece position easily to break.
Accompanying drawing explanation
The accompanying drawing that forms the application's a part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.
Accompanying drawing 1 is the outside drawing of existing binding clip;
Accompanying drawing 2 is cut-open views of existing binding clip;
Accompanying drawing 3 is sectional views of breaking line preventive binding clip of the present utility model;
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: as shown in Figure 3, breaking line preventive binding clip of the present utility model, the binding clip left clip body 1.1, the right clip body 1.2 that comprise metal, left clip body 1.1 and right clip body 1.2 are coupling by rotating shaft 3, torque spring 4 is housed in rotating shaft, two external parts of torque spring 4 act on respectively the inner side of left clip body 1.1 and right clip body 1.2, and left clip body 1.1 lower end covers have left insulating jacket 2.1, and the lower end cover of right clip body 1.2 has right insulating jacket 2.2; The end of wire 5 first through the lower end of right insulating jacket 2.2, walk around the upper end of torque spring 4, from the lower end of left insulating jacket 2.1, pass again, again through the lower end of right insulating jacket 2.2, then interior and be welded and fixed with the inwall of left clip body 1.1 around to left clip body 1.1 from torque spring 4 below, this wire end has one section of welding position being welded and fixed 6.
The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification are all encompassed among the scope of the claims of the present utility model.
Claims (2)
