Description
Technical field
The utility model relates to appliance field, is specifically related to a kind of isolating switch that can reduce contact heating.
Background technology
Existing isolating switch (disconnecting link) particularly GW4 type isolating switch single loop often in contact design, such result is after operation one section is taken time, because oxidation and compression spring fatigue after, between its contact, clamping force can reduce, and causes isolating switch to generate heat.Simultaneously also because be single circuit design, so also easily generate heat when load one is large, not only isolating switch heating just needs to carry out power failure process to loop, loses load but also increases production cost, so it is extremely urgent to solve isolating switch heating problem.
Utility model content
In sum, for solving existing technical problem, technical problem to be solved in the utility model is to provide a kind of isolating switch that can reduce contact heating.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of isolating switch that can reduce contact heating, comprise male contact cylindricality fulgurite and female contact cylindricality fulgurite, one end of described female contact cylindricality fulgurite is fixed on the inside of female contact U-board, one end of described public contact cylindricality fulgurite is circumscribed with fixed block, described fixed block is circumscribed with conducting block away from one end of described public contact cylindricality fulgurite, one group of fingertip is respectively equipped with in the upper and lower of described conducting block, the one end being in the described fingertip of upper and lower is arranged on top and the bottom of described conducting block respectively by screw I, female contact U-board one end far away apart from described female contact cylindricality fulgurite is stated by elastic card residence in its other one end,
One group of soft copper band is also respectively equipped with in the upper and lower of described public contact cylindricality tube ends, the one end being in the described soft copper band of upper and lower is arranged on top and the bottom of described public contact cylindricality tube ends respectively by screw II, state fixed block by elastic card residence between its other one end, and this end extends to described fingertip one end away from described female contact U-board.
The beneficial effects of the utility model are: between public contact cylindricality tube ends and fixed block, set up one group of soft copper band, on the one hand when ensureing that original contact is constant, add the contact of some faces again, the exposed area of disconnecting link contact can be reduced on the one hand in addition, thus reach the object reducing oxidation.
Further, described public contact cylindricality fulgurite is also connected by wire with described fingertip.
Above-mentioned further beneficial effect is: increase an auxiliary current loop, the electric current that isolation switch contact can be made to pass through doubles.
Further, the end of described public contact cylindricality fulgurite is welded with described fixed block.
Further, one end of cylindricality fulgurite is fixed on the inside of described female contact U-board by screw III.
Accompanying drawing explanation
Fig. 1 is figure of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
In accompanying drawing, the list of parts representated by each label is as follows:
1, public contact cylindricality fulgurite, 2, female contact cylindricality fulgurite, 3, female contact U-board, 4, fixed block, 5, conducting block, 6, fingertip, 7, screw I, 8, soft copper band, 9, screw II, 11, screw III.
Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As illustrated in fig. 1 and 2, a kind of isolating switch that can reduce contact heating, comprise male contact cylindricality fulgurite 1 and female contact cylindricality fulgurite 2, one end of described female contact cylindricality fulgurite 2 is fixed on the inside of female contact U-board 3 by screw III 11, one end of described public contact cylindricality fulgurite 1 is circumscribed with fixed block 4, described fixed block 4 is circumscribed with conducting block 5 away from one end of described public contact cylindricality fulgurite 1, and the end of wherein said public contact cylindricality fulgurite 1 is welded with described fixed block 4.One group of fingertip 6 is respectively equipped with in the upper and lower of described conducting block 5, the one end being in the described fingertip 6 of upper and lower is arranged on top and the bottom of described conducting block 5 respectively by screw I 7, state female contact U-board 3 one end far away apart from described female contact cylindricality fulgurite 2 between its other one end by elastic card residence.
One group of soft copper band 8 is also respectively equipped with in the upper and lower of described public contact cylindricality fulgurite 1 end, the one end being in the described soft copper band 8 of upper and lower is arranged on top and the bottom of described public contact cylindricality fulgurite 1 end respectively by screw II 9, state fixed block 4 by elastic card residence between its other one end, and this end extends to described fingertip 6 one end away from described female contact U-board 3.The end of existing middle public contact cylindricality fulgurite 1 is welded with described fixed block 4, the disconnecting link contact mutual when closing position is all out of shape the elastic force of generation each other from fingertip 6, the tired pressure later of fingertip 6 self can decline and cause contact inadequate, thus causes disconnecting link to generate heat.By approaching at contact site nut, the possibility that after so just can effectively preventing the equipment time limit remote, elastic pressure declines.The utility model also sets up one group of soft copper band 8 between the end and fixed block 4 of public contact cylindricality fulgurite 1, on the one hand when ensureing that original contact is constant, then adds the contact of some faces, conductive area is increased; The exposed area of disconnecting link contact can be reduced on the one hand in addition, thus reach the object reducing oxidation.
Described public contact cylindricality fulgurite 1 is also connected by wire 10 with described fingertip 6, forms a current circuit.Increase an auxiliary current loop, the electric current that isolation switch contact can be made to pass through doubles.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
