The first pipeline that red copper is made, logical cooling water in described first pipeline, the outer sheath of the first pipeline is provided with one and is made up of pyrite
Second pipe, be provided with two ring for fixings for connecting copper bar outside second pipe, described second pipe outer sheath is provided with
First insulation sleeve and the second insulation sleeve, described first insulation sleeve and the cooperation of the second insulation sleeve are fixed on capacitor case, existing
The first pipeline and second pipe typically fixed by brazing, solder joint is positioned at the end of the second pipe of capacitor protector body,
During use, two ring for fixings connect copper bar, and copper bar is energized, and electric current passes through second pipe, solder joint and the first pipeline successively, due to
The electric current that water-cooling terminal typically passes through is relatively big, and therefore caloric value is very big, owing to there is gap between the first pipeline and second pipe,
Therefore the poor effect of heat transfer, radiating effect is less desirable, and existing water-cooling terminal typically can only bear about 2000A
Electric current, if electric current strengthens again, then owing to heat radiation reason water-cooling terminal can be burned out.
In order to solve the problems referred to above, Chinese patent CN103456488B discloses a kind of Large-current-resisttype type water-cooling terminal, bag
Including the first pipeline that red copper is made, described first pipeline outer sheath is provided with the second pipe that pyrite is made, sets outside second pipe
Being equipped with the ring for fixing for connecting copper bar, described second pipe outer sheath is provided with the first insulation sleeve and the second insulation sleeve, and described
One insulation sleeve and the cooperation of the second insulation sleeve are fixed on capacitor case, and described first pipeline and the welding of described second pipe are solid
Fixed, it is provided with implant between described first pipeline and described second pipe, described implant utilizes the first pipeline and the second pipe
Delayed heat melting after road welding penetrates in the gap of the first pipeline and second pipe, and described implant forms contact tube, capacitor
The described second pipe end in outside is provided with bulge loop.This water-cooling terminal passes through brazing between the first pipeline and second pipe
Delayed heat melting scolding tin so that scolding tin forms contact tube in being filled in the gap of the first pipeline and second pipe, and in practical operation
During to there will be the gap between the first pipeline and second pipe uneven, and the scolding tin illiquidity melted or because
First pipeline in somewhere and second pipe are close to and cannot be flow at solder joint, cause between the first pipeline and second pipe still
There is space.
Summary of the invention
The present invention is directed to prior art not enough, it is provided that a kind of capacitor terminal, being prevented from of this binding post
Gap is produced between first pipeline and second pipe, and easier for installation.
In order to solve above-mentioned technical problem, the present invention is addressed by following technical proposals: a kind of capacitor terminal
Son, the first pipeline made including red copper, described first pipeline outer sheath is provided with the second pipe that pyrite is made, outside second pipe
Side is provided with the ring for fixing for connecting copper bar, and described second pipe outer sheath is provided with the first insulation sleeve and the second insulation sleeve, institute
State the first insulation sleeve and the cooperation of the second insulation sleeve is fixed on capacitor case, described first pipeline and the welding of described second pipe
Fixing, described first pipeline is radially arranged bulge loop, described first pipeline has been arranged with outside there is externally threaded sleeve pipe, institute
Stating bulge loop with described sleeve pipe by protruding and groove fit, described sleeve pipe includes the copper lid away from described bulge loop and stannum system
Pipe, is provided with female thread, described female thread and described external screw thread and coordinates in described second pipe, described bulge loop and described second pipe
Road welds, the fusing when welding of described stannum tubulation, and solidification forms contact tube after cooling.Use this structure will overlap when mounted
Pipe is inserted in the first pipeline, and is screwed in second pipe with sleeve pipe by the first pipeline, is then welded with second pipe by bulge loop,
Stannum tubulation described in welding process melts, and then rotates the stannum of copper lid extruding fusing, reduces gap, so that stannum and first
Pipeline and second pipe connect tightr so that electric conductivity between the first pipeline and second pipe and heat conductivility are more
Good, copper lid ensure that the axiality of the first pipeline and second pipe simultaneously, it is ensured that between the first pipeline and second pipe
Gap uniformity.
In technique scheme, it is preferred that be provided with the nut for being inserted in spanner on described copper lid.On copper lid
Nut, convenient rotation copper lid are set.
The present invention compared with prior art, has the advantages that sleeve pipe is inserted in the by employing this structure when mounted
In one pipeline, and the first pipeline is screwed in second pipe with sleeve pipe, then bulge loop is welded with second pipe, in welding process
Described in the fusing of stannum tubulation, then rotate the stannum of copper lid extruding fusing, reduce gap, so that stannum and the first pipeline and the
Two pipelines connect tightr so that electric conductivity and heat conductivility between the first pipeline and second pipe are more preferable, copper
