Abstract

A kind of isolation switch contact, comprises support bar and the supporting seat being fixed in support bar one end, at supporting seat relative on support bar two sides, and intrinsic three fingertips of symmetrical spiral shell respectively; The sideline of three described fingertip one end is parallel with the sideline, one end of supporting seat side, it is characterized in that: be bolted with all-in-one-piece fingertip elastic pressuring plate in the periphery of three fingertips, and at least two-layer epoxy resin heat shield is provided with between its all-in-one-piece fingertip elastic pressuring plate and three fingertips, the utility model can ensure 3 fingertip uniform force, fingertip by fingertip spring pressuring plate pressure at grade, ensure its fully contacting with contact, reduce contact resistance.

Description

A kind of isolation switch contact
Technical field
The utility model relates to a kind of isolating switch, particularly a kind of isolation switch contact.
Background technology
Isolating switch is mainly made up of base for supporting, conductive carrier, operating member etc.According to the statistics of occurred the in recent years fault isolating switch of Yichang electric company, can find out outdoor type isolating switch run in heating problem more frequent.Heating accident mainly occurs in the junction of conductive shield, contact, fingertip, switch terminal and device clamp and wire.Caused by the reason of isolating switch heating mainly contacts, the resistance of current-carrying part increases, existing switch touching thrum spring is march-past, fingertip spring is also thinner with the insulation resin thermal insulation board between fingertip, only has one deck, the contact of outdoor type isolating switch and the contact site of fingertip are linear contact lay, but also are a desultory line (bar shaped fingertips).
When each vertical setting of types of isolating switch fingertip not in one plane time, this can cause contact and fingertip to be contacted from face under normal circumstances becoming point cantact, thus increase contact resistance, outdoor type isolating switch is easily generated heat in running, thus burns out isolating switch.By carrying out observation analysis to the sampling of actual field, the fingertip of its each vertical setting of types of isolating switch that the overwhelming majority burns out is not in one plane.The main cause of heating during this causes outdoor type isolating switch in this project to run just.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of isolation switch contact, and each fingertip can be allowed at same plane, and the better isolation switch contact of thermal insulation.
In order to solve the problem, the technical solution of the utility model is:
A kind of isolation switch contact, comprises support bar and the supporting seat being fixed in support bar one end, at supporting seat relative on support bar two sides, and intrinsic three fingertips of symmetrical spiral shell respectively; The sideline of three described fingertip one end is parallel with the sideline, one end of supporting seat side, it is characterized in that: be bolted with all-in-one-piece fingertip elastic pressuring plate in the periphery of three fingertips, and be provided with at least two-layer epoxy resin heat shield between its all-in-one-piece fingertip elastic pressuring plate and three fingertips.
Described all-in-one-piece fingertip elastic pressuring plate is that stainless steel material is made.
Technique effect of the present utility model is:
Three fingertip elastic pressuring plates are changed into an integral type stainless steel fingertip elastic pressuring plate, it is heated more even, serious deformation can not be produced easily, thus 3 fingertip uniform force can be ensured, fingertip by fingertip spring pressuring plate pressure at grade, ensure its fully contacting with contact, reduce contact resistance; At least two-layer epoxy resins insulation thermal insulation board will be changed between fingertip spring pressuring plate and fingertip into, play effect that is heat insulation and insulation better, avoid fingertip spring follow the string because being excessively heated or deformation occurs.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is the end view of known a kind of isolation switch contact;
Fig. 2 is that the master of known a kind of isolation switch contact looks explosive view:
Fig. 3 is the three-dimensional structure diagram of known a kind of isolation switch contact;
Fig. 4 is end view of the present utility model;
Fig. 5 is that master of the present utility model looks explosive view;
Fig. 6 is stereoscopic mechanism figure of the present utility model;
In figure; Support bar 1, supporting seat 2, fingertip 3, epoxy resin heat shield 4, fingertip elastic pressuring plate 5, packing ring and spring pad 6, screw 7, integral type fingertip elastic pressuring plate 50.
Embodiment
A kind of isolation switch contact that Fig. 1 to Fig. 3 mentions for foregoing Background Section, as can be seen from the figure described fingertip elastic pressuring plate 5 be three independently, compress respectively in contrast in three fingertips 3, because three fingertips are independently, therefore when certain a slice fingertip because electric arc or below the words of loosened screw, three fingertips 3 will be caused not to be in a plane, and epoxy resin heat shield 4 only has one deck, can not be well heat insulation, and then cause isolating switch easily to generate heat in running, thus burn out isolating switch.
In the same plane in order to ensure three fingertips, and there is certain thermal insulation, the utility model have employed the structure as shown in Fig. 4 to 6: comprise support bar 1 and the supporting seat 2 being fixed in support bar 1 one end, at supporting seat 2 relative on support bar 1 two sides, intrinsic three fingertips 3 of symmetrical spiral shell respectively; The sideline of three described fingertip 3 one end is parallel with the sideline, one end of supporting seat 2 side, it is characterized in that: be bolted with all-in-one-piece fingertip elastic pressuring plate 50 in the periphery of three fingertips 3, and be provided with at least two-layer epoxy resin heat shield 4 between its all-in-one-piece fingertip elastic pressuring plate 50 and three fingertips 3.Described all-in-one-piece fingertip elastic pressuring plate 50 is made for stainless steel material.
Three fingertip elastic pressuring plates 5 are changed into an integral type stainless steel fingertip elastic pressuring plate 50, it is heated more even, serious deformation can not be produced easily, thus 3 fingertip uniform force can be ensured, that is afraid of the words having a loosened screw, fingertip 3 also can be pressed at grade by integral type fingertip spring pressuring plate 50, ensures its fully contacting with contact 3, reduces contact resistance; At least two-layer epoxy resins insulation heat shield 4 will be changed between fingertip spring pressuring plate and fingertip into, play effect that is heat insulation and insulation better, avoid fingertip spring 50 follow the string because being excessively heated or deformation occurs.
