Abstract
A kind of middle contact of isolating switch, comprise conducting rod, holder, protective cover, static contact finger, moving contact, arc spring lamination and strut, described static contact finger is oppositely arranged in the both sides up and down of described holder, holder is connected with described conducting rod, described in each, the end of static contact finger arranges a described arc spring lamination, and the front end of arc spring lamination is positioned at the middle and upper part of static contact finger; In the inner side of described static contact finger, fix a strut, the strut on two static contact fingers that are oppositely arranged is also oppositely arranged, the height of two described struts and the height that is less than described holder.The utility model reliability is high, and simple in structure, and cost is low, can not only increase contact, and can not produce shunting, and static contact finger can not bend yet.
Description
Technical field
the utility model relates to a kind of isolating switch, specifically a kind of middle contact being used on isolating switch.
Background technology
In the middle of existing isolating switch in structure of contact terminal, having a kind of is to increase the contact between static contact finger and moving contact a spring is set between static contact finger, and its structure as shown in Figure 1.There is following problem in this spline structure: 1, when isolator operation its spring pressure only can increase static contact finger while closing a floodgate and and moving contact between contact, but in the time of can not stoping isolating switch separating brake, static contact finger is subject to separating brake reaction force and excessively returns and cause crooked situation to occur, like this, due to contact static contact finger part flexural deformation in the middle of easily making after multi-pass operation, thereby moving contact contradicts each other and the situation generation of operating difficulties with crooked static contact finger while causing closing a floodgate.Under this state, operations staff overexerts as operation, and conflict strength is excessive, very likely because operation causes and causes serious accident by Rupture of Post Insulator by force.2, a spring is set between static contact finger and can causes spring shunting, spring its elastic potential energy after long-time overheated reduces, can not well increase static contact finger and and moving contact between contact.
Utility model content
The shortcoming existing in order to overcome above-mentioned prior art, the purpose of this utility model is to provide a kind of static contact finger of avoiding crooked, and can increase static contact finger and and moving contact between the middle contact of isolating switch of contact.
In order to address the above problem, the utility model is by the following technical solutions: a kind of middle contact of isolating switch, comprise conducting rod, holder, protective cover, static contact finger and moving contact, described static contact finger is oppositely arranged in the both sides up and down of described holder, holder is connected with described conducting rod, it is characterized in that, it also comprises arc spring lamination and strut, described in each, the end of static contact finger arranges a described arc spring lamination, and the front end of arc spring lamination is positioned at the middle and upper part of static contact finger; In the inner side of described static contact finger, fix a strut, the strut on two static contact fingers that are oppositely arranged is also oppositely arranged, the height of two described struts and the height that is less than described holder.
Preferably, described arc spring lamination is bolted setting, and described bolt is fixed on described holder through after described static contact finger.
Preferably, described strut is insulating bar, the height of two described struts and than the little 0.2-0.8cm of the height of described holder.
The beneficial effects of the utility model are: its reliability is high, and simple in structure, and cost is low; It is at the arranged outside shell fragment of static contact finger, and the active force of shell fragment acts on the middle and upper part of static contact finger, has not only increased contact, and can not produce shunting; By in static contact finger inner side, insulation brace rod being set, guaranteed that static contact finger can not bend.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the utility model is described further:
Fig. 1 is existing middle structure of contact terminal schematic diagram;
Fig. 2 is structural representation of the present utility model.
In figure, 1 conducting rod, 2 holders, 3 protective covers, 4 static contact fingers, 5 moving contacts, 6 arc spring laminations, 7 struts.
Embodiment
As shown in Figure 2, specific embodiment of the utility model comprises conducting rod 1, holder 2, protective cover 3, static contact finger 4, moving contact 5, arc spring lamination 6 and strut 7.
Described static contact finger 4 is oppositely arranged in the both sides up and down of described holder 2, holder 2 is connected with described conducting rod 1, described in each, the end of static contact finger 4 arranges a described arc spring lamination 6, the end of arc spring lamination 6 can directly be fixed on the end of static contact finger 4, preferably, described arc spring lamination 6 is bolted setting, the end of static contact finger 4 arranges through hole, described bolt is fixed on described holder 2 through after the through hole of static contact finger 4 ends, the front end of arc spring lamination 6 is positioned at the middle and upper part of static contact finger 4, be half of the horizontal length of arc spring lamination 6 length that is greater than static contact finger 4, the horizontal length of preferred arc spring lamination 6 equals 2/3rds of static contact finger 4 length, can guarantee like this contact between static contact finger 4 and moving contact 5.
In the inner side of described static contact finger 4, fix a strut 7, strut 7 on two static contact fingers 4 that are oppositely arranged is also oppositely arranged, described strut 7 is preferably insulating bar, the height of two described struts 7 and the height that is less than described holder 2, preferably, the height of two described struts and than the little 0.2-0.8cm of the height of described holder.Strut 7 docking on two static contact fingers 4 that are oppositely arranged after separating brake, have stoped static contact finger 4 flexural deformation under the active force of arc spring lamination 6.
The above is preferred implementation of the present utility model; for those skilled in the art; not departing under the prerequisite of the utility model principle, can also make some improvements and modifications, these improvements and modifications are also regarded as protection range of the present utility model.
