Abstract
The utility model provides a pair of jointing clamp comprising a primary clamp body and an auxiliary clamp body. The two clamp bodies are cooperated with each other in an intersecting mode by a rotating shaft. Concave portions are arranged on occlusal surfaces of clamp mouths of the primary clamp body and the auxiliary clamp body; and grooves that are extended to two edges of the clamp mouths are arranged at two sides of the concave portions. A through hole directly facing the concave portion and penetrating the auxiliary clamp body is arranged on the auxiliary clamp body. An electric heating device is arranged at a position approaching the primary clamp mouth inside the primary clamp body and is electrically connected with an attaching plug. And the tail portions of the primary clamp body and the auxiliary clamp body are wrapped by insulated heat-resistant tail cases. According to the jointing clamp provided by the utility model, power line ends can be firmly welded to complete the wire jointing work; moreover, the jointing clamp can be operated conveniently and the jointing efficiency is high.
Description
Technical field
The utility model relates to a kind of electrician's instrument, particularly, is a kind of jointing clamp that is applied in the power line wiring process.
Background technology
In various civilian circuit, electrician's general bark knife that adopts earlier when wiring divests the end of a thread cot, and then exposed copper cash is twined overlap joint, swathes with insulating tape after the completion again.The electric wire node that this kind mode of connection is accomplished is owing to only rely on copper cash to tangle to connect the end of a thread, therefore as easy as rolling off a log the getting loose in the process of pullling of electric wire.
In fact, the end of a thread connects and adopt welding procedure to accomplish the most reliably, yet when adopting common electric iron to weld, operation is inconvenience very, and wiring efficient is lower.
The utility model content
In order to address the above problem, the purpose of the utility model is to provide a kind of jointing clamp, and this kind jointing clamp is weld power the end of a thread securely both, accomplishes the wiring operation, and easy to operate, and wiring efficient is higher.
The utility model solves the technical scheme that its technical problem adopted: this jointing clamp comprises positive caliper, secondary caliper, and two calipers intersect through rotating shaft and cooperate; Be equipped with a depression on the jaw occlusal surface of said positive caliper and secondary caliper, said depression both sides have the groove that extends to the jaw two edges; Offer together over against said depression on the secondary jaw and run through the through hole of secondary jaw; The positive jaw of said positive caliper inner near place is provided with electric calorifie installation, and this electric calorifie installation electrically connects attaching plug; Said positive caliper and secondary caliper afterbody are by the heat-resisting tail shell parcel of insulation.
As preferably, be shaped on coarse lines in the said groove, slide in groove to prevent electric wire.
As preferably, the said through hole of secondary jaw and the handing-over edge smooth transition of the said depression on the secondary jaw of running through is beneficial to reject the welding raw material that is condensed in this place.
As preferably, the rotating shaft that articulates said positive caliper and secondary caliper is a spring shaft, and this spring shaft is in nature following time, and the jaw of said positive caliper and secondary caliper compresses each other.
The beneficial effect of the utility model is: this jointing clamp is in when work, can be with two electric power the end of a thread to be connected puts into the depression of positive jaw respectively along said groove from both sides, and makes positive jaw and the mutual interlock of secondary jaw; With fixing electric power the end of a thread, and give said electric calorifie installation heating, make positive jaw inboard be in high hot state through attaching plug; It is broken that thereby the cot that makes the end of a thread place burns; And make the copper cash touching together, at this moment, can scolding tin be extend into the recess of said positive jaw through the through hole of said secondary jaw; And be melted; Thereby electric power the end of a thread is firmly welded, then can the rubber bar material be stretched in the said through hole, after the fusing said power lug insulation is wrapped up.This kind jointing clamp is weld power the end of a thread securely both, accomplishes the wiring operation, and easy to operate, and wiring efficient is higher.
Description of drawings
Fig. 1 is the structural representation of an embodiment of this jointing clamp.
Fig. 2 is a work sketch map embodiment illustrated in fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
In the embodiment shown in fig. 1, this jointing clamp comprises that positive caliper 1, secondary caliper 2, two calipers intersect through rotating shaft 6 and cooperates; Be equipped with a depression 12 on the jaw occlusal surface of said positive caliper 1 and secondary caliper 2, said depression 12 both sides have the groove 13 that extends to the jaw two edges, and said depression 12 ovalizes, its major axis and said groove 13 conllinear; Offer together over against said depression 12 on the secondary jaw 21 and run through the through hole 22 of secondary jaw 21; The positive jaw of said positive caliper 1 inner near 11 places are provided with electric calorifie installation 4, and this electric calorifie installation 4 electrically connects attaching plug 5, and its concrete structure is identical with the common electrical flatiron; Said positive caliper 1 wraps up by the heat-resisting tail shell 3 of insulation with secondary caliper 2 afterbodys.
Above-mentioned jointing clamp is shaped on coarse lines in the said groove 13, and this coarse lines can be and ring grain groove 13 orthogonal axes, that gather side by side, slides in groove 13 to prevent electric wire.
Above-mentioned jointing clamp, the said through hole of secondary jaw 21 and the handing-over edge smooth transition of the said depression 12 on the secondary jaw 21 of running through is beneficial to reject the welding raw material that is condensed in this place.
Above-mentioned jointing clamp, the rotating shaft 6 that articulates said positive caliper 1 and secondary caliper 2 is spring shaft, and this spring shaft is in nature following time; The jaw of said positive caliper 1 and secondary caliper 2 compresses each other; Like this, after electric power the end of a thread bitten, the electrician just need not firmly to clutch jointing clamp again; Thereby saved strength, also can vacate more and do other operation on the other hand.
The work sketch map of above-mentioned jointing clamp is as shown in Figure 2, in when work, can be with two electric power the end of a thread 7 to be connected puts into the depression 12 of positive jaw 11 respectively along said groove 13 from both sides; And make positive jaw 11 and secondary jaw 21 mutual interlocks, with fixing electric power the end of a thread 7, and heat to said electric calorifie installation 4 through attaching plug 5; Make positive jaw 11 inboards be in high hot state, thereby make the cot burning at the end of a thread 7 places broken, and make the copper cash touching together; At this moment, can scolding tin 8 be extend into depression 12 places of said positive jaw 11 through the through hole 22 of said secondary jaw 21, and be melted; Thereby electric power the end of a thread 7 is firmly welded; Then can the rubber bar material be stretched in the said through hole 22 (not shown, its process is with identical to the operation of scolding tin 8), after the fusing said power lug 7 insulation wrapped up.This kind jointing clamp is weld power the end of a thread securely both, accomplishes the wiring operation, and easy to operate, and wiring efficient is higher.
