Description
Technical field
The invention belongs to capacitor technology field, specifically a kind of capacitor terminal.
Background technology
Capacitor is the electronic component commonly used in circuit, and large-scale capacitor is big, it is necessary to using cooling water due to caloric value
To cool down ampere wires, cooling water be linked at transformer case need set water-cooling terminal, present water-cooling terminal include by
First pipeline made of red copper, cooling water is led in first pipeline, and the outer sheath of the first pipeline is made up provided with one of brass
Second pipe, two retainer plates for connecting copper bar are provided with the outside of second pipe, the second pipe outer sheath is provided with
First insulation sleeve and the second insulation sleeve, first insulation sleeve and the second insulation sleeve, which coordinate, to be fixed on capacitor case, existing
The first pipeline and second pipe typically fixed by brazing, solder joint is located at the end of the second pipe in capacitor protector body,
In use, two retainer plate connecting copper bars, be powered on copper bar, electric current by second pipe successively, solder joint and the first pipeline, due to
The electric current that water-cooling terminal typically passes through is larger, therefore caloric value is very big, due to gap be present between the first pipeline and second pipe,
Therefore the poor effect of heat transfer, radiating effect is less desirable, and existing water-cooling terminal can only typically bear 2000A's or so
Electric current, if electric current increases again, then because radiating reason water-cooling terminal can be burned out.
In order to solve the above problems, Chinese patent CN103456488B discloses a kind of Large-current-resisttype type water-cooling terminal, bag
The first pipeline made of red copper is included, the first pipeline outer sheath is provided with second pipe made of brass, set on the outside of second pipe
It is equipped with the retainer plate for connecting copper bar, the second pipe outer sheath is provided with the first insulation sleeve and the second insulation sleeve, and described
One insulation sleeve and the second insulation sleeve, which coordinate, to be fixed on capacitor case, and first pipeline and second pipe welding are solid
It is fixed, filler is provided between first pipeline and the second pipe, the filler utilizes the first pipeline and the second pipe
Delayed heat melting after road welding is penetrated into the gap of the first pipeline and second pipe, and the filler forms contact tube, capacitor
The second pipe end set in outside has bulge loop.The water-cooling terminal passes through the brazing between the first pipeline and second pipe
Delayed heat melting scolding tin so that scolding tin is filled in formation contact tube in the gap of the first pipeline and second pipe, and in practical operation
During occur that the gap between the first pipeline and second pipe is uneven, and melt scolding tin illiquidity or because
First pipeline and second pipe in somewhere are close to and can not flow at solder joint, cause between the first pipeline and second pipe still
Space be present.
The content of the invention
In view of the shortcomings of the prior art, providing a kind of capacitor terminal, this binding post can prevent the present invention
Gap is produced between first pipeline and second pipe, and it is easier for installation.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：A kind of capacitor terminal
Son, including the first pipeline made of red copper, the first pipeline outer sheath are provided with second pipe made of brass, outside second pipe
Side is provided with the retainer plate for connecting copper bar, and the 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, first pipeline and second pipe welding
It is fixed, bulge loop is radially arranged on first pipeline, outside is arranged with first pipeline has externally threaded sleeve pipe, institute
State bulge loop with described sleeve pipe by raised and groove to coordinate, described sleeve pipe includes tin tubulation and the copper away from the bulge loop
Cover, internal thread is provided with the second pipe, the internal thread and the external screw thread coordinate, the bulge loop and the described second pipe
Road welds, and the tin tubulation melts in welding, and solidification forms contact tube after cooling.When mounted will set using the structure
Pipe is inserted in the first pipeline, and the first pipeline and sleeve pipe are screwed in second pipe, then welds bulge loop and second pipe,
Tin tubulation described in welding process melts, and then rotates the tin of copper lid extruding fusing, gap is reduced, so that tin and first
Pipeline connects even closer with second pipe so that electric conductivity and heat conductivility between the first pipeline and second pipe are more
Good, copper lid can ensure the axiality of the first pipeline and second pipe simultaneously, ensure between the first pipeline and second pipe
Gap uniformity.
In above-mentioned technical proposal, it is preferred that the copper covers the nut being provided with for being inserted in spanner.Covered in copper
Nut is set, it is convenient to rotate copper lid.
The present invention compared with prior art, has the advantages that：Sleeve pipe is inserted in when mounted using the structure
In one pipeline, and the first pipeline and sleeve pipe are screwed in second pipe, then welded bulge loop and second pipe, in welding process
Described in the fusing of tin tubulation, then rotate the tin of copper lid extruding fusing, reduce gap, so that tin and the first pipeline and the
The connection of two pipelines is even closer so that the electric conductivity and heat conductivility between the first pipeline and second pipe are more preferable, copper
Lid can ensure the axiality of the first pipeline and second pipe simultaneously, ensure that the gap between the first pipeline and second pipe is equal
It is even.
