Problems solved by technology

The connector has a smooth and elegant appearance, large conductive contact surface, high contact pressure, and high connection reliability, but there are still limitations of insufficient connection and unsatisfactory tensile strength. Tensile, it is bound to increase the end caps at both ends to press tightly to the middle to push the inner tapered sleeve to move to the middle. At this time, it is easy to deform the busbar of the middle pipe and reduce the electrical conductivity

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as figure 1 , 2 The shown pipe bus taper connection device includes pipe bus 2 and inner sleeve 6, wherein:

[0022] The inner side wall of the sleeve end 9 of the pipe busbar 2 is provided with an inner conical surface 8 with a larger inner diameter at the outer end, and a stopper 3 is provided at the end of the outer wall.

[0023] The outer wall of the inner sleeve 6 embedded in the connecting end 10 is provided with an outer conical surface 4 with a smaller outer diameter and matched with the inner conical surface 8, and a positioning part 5 is provided on the inner side; The diameter is 70.03mm, the inner outer diameter is 72.03mm, and of which:

[0024] The inner inner diameter of the inner conical surface 8 on the sleeve end 9 of the pipe busbar 2 is slightly smaller than the outer diameter of the outer end of the outer co...

Abstract

The invention relates to a conical connecting device for a tubular bus bar. An inner side wall at a tubular bus bar coupling end and an outer side wall at an inner bushing connecting end are set as matched conical surfaces through the connecting device; and the tubular bus bar is tightly and fixedly coupled with an inner bushing by using a compressor through threaded contraction. According to the connecting device, convenient and rapid connection between tubular bus bars as well as the tubular bus bars and other equipment is realized, and connection between the tubular bus bars as well as between the tubular bus bars and other equipment is firm and compact; and the connecting device is elegant in appearance, has high tensile strength, uniform surface joint and excellent current conducting performance, and can be widely applied in the field of electric power transmission and transformation.

Description

technical field [0001] The invention relates to the technical field of electric power transmission and transformation, in particular to a pipe bus tapered connection device. Background technique [0002] There are two main types of existing technologies for pipe bus connection, one is the external compression type, that is, there are 4 slits at the connection end of the pipe bus, and the inner sleeve is directly embedded in the pipe bus connection, and then connected to the pipe bus. Use a hoop to tighten the outer circle of the end and lock the bolts. This method has the limitations of uneven appearance, unsightly appearance, troublesome follow-up construction, large material consumption, and high cost; the other type is based on the above connection method. After welding the gap at the connecting end of the pipe busbar to make it tightly connected with the inner casing, the hoop is removed. This method overcomes the defects of flat appearance, unsightly appearance, high ma...
