Description

Isolation switch contact assembly
Technical field
The utility model relates to a kind of isolating switch and manufactures field, and more particularly, it relates to a kind of isolation switch contact assembly.
Background technology
High voltage isolator is the electric equipment that in electric power system, use amount is maximum, existing high voltage isolator generally adopts finger contact assembly, these finger contact assemblies are generally two art level fracture isolating switch, comprise relative a pair fingertip substantially and can be inserted into this to the contact in fingertip, described to fingertip between be provided with resetting device.
And resetting device comprises stationary body and tension spring, tension spring is arranged in stationary body, fingertip is conflicted in stationary body side, tension spring two ends are separately fixed on fingertip, fingertip is fixedly clamped main body, when involutory contact inserts people, fingertip is made to overcome the elastic force of tension spring, fingertip is rotated to side, after involutory contact inserts, fingertip is made to conflict closely on involutory contact by the elastic force of tension spring, and cause elastic force easily to be lost because tension spring is in extended state for a long time, and spring is positioned at stationary body, thus electric current flows through tension spring, make the easy lost its bounce of tension spring, and when involutory contact inserts fast, fingertip is caused to be subject to larger impact, easily cause the deflection that fingertip is excessive, the tie point of tension spring is caused to destroy, or tension spring excessive tensile and losing efficacy, and tension spring is not easy to regulate elastic force, can only change after causing the elastic force of tension spring to reduce, thus improve the cost of maintenance, owing to being provided with multiple fingertip, the corresponding multiple tension spring of multiple fingertip, cause each spring controlled distance different, the pressure causing fingertip to be subject to is not identical yet, thus cause pressure uneven, thus it is crooked to make involutory contact produce, thus affect the connection of fingertip and involutory contact.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of isolation switch contact assembly facilitating even regulation elastic force.
For achieving the above object, the utility model provides following technical scheme: a kind of isolation switch contact assembly, comprise main contact and involutory contact, described main contact comprises conductive base, several fingertips, resetting device, fingertip described in several is connected to conductive base both sides, described resetting device comprises the stationary body of conflicting for fingertip, several elastic components, described elastic component is compression spring, described stationary body is provided with connecting rod, described connecting rod runs through stationary body, fingertip is run through respectively in described connecting rod two ends, described compression spring is set in connecting rod two ends respectively, described connecting rod two ends have all been threaded nut, conflict in fingertip side in described compression spring one end, the described compression spring other end is conflicted in nut side.
Preferably, described stationary body is the flexure strip of " U " font.
Preferably, described stationary body opening part is fixedly connected on conductive base.
Compared with prior art, the beneficial effects of the utility model are: when inserting syncephalon, fingertip is rotated to side, because compression spring is conflicted in fingertip side, and compression spring is subject to connecting rod fixes, thus when fingertip rotates, compression spring is squeezed, thus make compression spring carry out accumulation elastic force, and all conflict on same connecting rod due to the compression spring at two ends, thus connecting rod effectively can balance the elastic force of pressure at two ends spring, make the compression spring amount of contraction at two ends identical, and compression spring compresses rear active force completely acts directly on connecting rod, thus compression spring can not continue compression, and then avoid the forfeiture of elastic force, thus effectively raise the life-span of use, and be positioned at fingertip side due to compression spring, thus electric current can not flow on the compression spring of side, thus effectively raise the useful life of compression spring, and when needing the elastic force regulating compression spring, from needs rotating nut, compression or the release of the compression spring at two ends can be regulated simultaneously, regulate the elastic force of compression spring very easily.
Accompanying drawing explanation
Fig. 1 is the stereogram of the utility model isolation switch contact Assemblies Example;
Fig. 2 is the enlarged drawing of A in Fig. 1.
Reference numeral: 1, main contact; 11, conductive base; 12, fingertip; 13, resetting device; 131, stationary body; 132, compression spring; 133, connecting rod; 134, nut; 2, involutory contact.
Embodiment
Referring to figs. 1 through Fig. 2, the utility model isolation switch contact Assemblies Example is described further.
A kind of isolation switch contact assembly, comprise main contact 1 and involutory contact 2, described main contact 1 comprises conductive base 11, several fingertips 12, resetting device 13, fingertip 12 described in several is connected to conductive base 11 both sides, described resetting device 13 comprises the stationary body 131 of conflicting for fingertip 12, several elastic components, described elastic component is compression spring 132, described stationary body 131 is provided with connecting rod 133, described connecting rod 133 runs through stationary body 131, fingertip 12 is run through at described connecting rod 133 two ends respectively, described compression spring 132 is set in connecting rod 133 two ends respectively, described connecting rod 133 two ends have all been threaded nut 134, conflict in fingertip 12 side in described compression spring 132 one end, described compression spring 132 other end is conflicted in nut 134 side, when inserting syncephalon, fingertip 12 is rotated to side, because compression spring 132 is conflicted in fingertip 12 side, and compression spring 132 is subject to connecting rod 133 fixes, thus when fingertip 12 rotates, compression spring 132 is squeezed, thus make compression spring 132 carry out accumulation elastic force, and all conflict on same connecting rod 133 due to the compression spring 132 at two ends, thus connecting rod 133 effectively can balance the elastic force of pressure at two ends spring 132, make compression spring 132 amount of contraction at two ends identical, and compression spring 132 compress completely after active force act directly on connecting rod 133, thus compression spring 132 can not continue compression, and then avoid the forfeiture of elastic force, thus effectively raise the life-span of use, and be positioned at fingertip 12 side due to compression spring 132, thus electric current can not flow on the compression spring 132 of side, thus effectively raise the useful life of compression spring 132, and when needing the elastic force regulating compression spring 132, from needs rotating nut 134, compression or the release of the compression spring 132 at two ends can be regulated simultaneously, regulate the elastic force of compression spring 132 very easily.
Described stationary body 131 is the flexure strip of " U " font, fingertip 12 is stayed alone in flexure strip side, when fingertip 12 rotates, fingertip 12 improves to the pressure of flexure strip, thus flexure strip internally caves in, thus make the rotational angle of fingertip 12 become large, thus the insertion making involutory contact 2 energy convenient.
Described stationary body 131 opening part is fixedly connected on conductive base 11, thus effectively avoids the larger deflection of stationary body 131 opening part generation, and follows the string, and effectively raises the useful life of stationary body 131.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
