The utility model discloses a new pipe type parallel clamp, which comprises an upper parallel clamp and a lower parallel clamp. The upper parallel clamp and the lower parallel clamp are semi-circular structures. The top of the upper parallel clamp is provided with a first protrusion, and the lower end is opened. The lower parallel clamp is a top opening, and the lower part which is far away from the opening direction is provided with a second protrusion, and the length of the first protrusion is less than that of the lower parallel clamp The length of the opening, the length of the second protrusion is less than the length of the opening of the upper parallel clamp, the first protrusion is matched with the opening of the lower parallel clamp, the second protrusion is matched with the opening of the upper parallel clamp, the lower parallel clamp is provided with a wiring hole, and the upper parallel clamp is clamped in the lower parallel clamp. The new type not only does not need to cut off the wire when crimping the wire and the wiring, but also solves the problem that the wire and the wiring leak out through the opening end of the parallel clamp when the hydraulic tong extrudes the wiring clamp, so that the two are closely contacted after crimping, the resistance is very small, and the heating is not generated, which meets the requirements of the large current circuit wiring.

一种新型管式并线夹
本技术涉及电力配件设备
,尤其涉及一种新型管式并线夹。
技术介绍
近年来,传统电力输线的导线并接时需要固定导线的螺丝和金属部件的并线夹,这种传统的并线夹体积一般较大,且包含金属构件成本也会较高。对于在导线中间另并接出一根线路的情况,如果布线较多且复杂,使用传统并线夹体积太大,接线处往往会形成一个很大的“包”,影响美观,如果直接把金属线绞绕在一起,硬质的金属导线,缠绕时会形成固定的形状,很容易引起松动导致的接触不良。随着技术的发展,现有技术中出现了一些并线夹,如一端开口的C型、两端开口的H型并线夹,虽然在使用时不用将导线截断,只用将导线和接线接触的地方把绝缘皮剥开后,直接通过开口端放入并线夹中,再通过液压钳压紧并线夹,使并线夹变形从而将导线和接线压紧,最后再将并线夹外围缠绕绝缘带,但是不管是一端开口的C型并线夹,还是两端开口的H型并线夹,因其存在开口结构,液压钳在压接并线夹时,不免导线和接线在外力作用下向并线夹开口端偏移,结果就会出现压接后的导线和接线通过开口端漏出并线夹,也就是不能实现并线夹压接后将导线和接线完全包裹压紧,有可能导致导线和压线接触不紧,尤其在大电流电路中,使用一段时间,就容易出现发热,导致线路故障。
技术实现思路
为了克服现有技术的上述缺点,本技术提供了一种新型管式并线夹,不仅在导线和接线压接时不需要将导线截断,直接将导线和接线放入并线夹内部,并线夹能够上下合上,且缝隙很小,解决了液压钳挤压并线夹时,导线和接线通过并线夹开口端漏出并线夹的问题,从而使导 ...
