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 fingertip is just conflicted in conductive base side by the elastic force of resetting device, and after involutory contact conflicts contact, contact easily produces along the side of conflicting with conductive base and rotates, thus makes original face contact change into linear contact lay, thus conductive area greatly reduces, improve resistance, thus contact point easily generates heat, and the energy that meeting loss is a large amount of, and the current/voltage at this time produced can produce certain change, thus cause contact point to produce electric spark, easily cause security incident.

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 be convenient to fingertip and conductive base and conducted electricity.

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, fingertip, resetting device, described fingertip is connected with resetting device, conflict in conductive base side in described fingertip one end, described fingertip is fixedly connected with conductive mechanism, and described conductive mechanism is connected with conductive base.

Described conductive mechanism comprises electroconductive elastic sheet, connector, and described electroconductive elastic sheet two ends are fixedly connected on fingertip with on conductive base respectively by connector.

The portion of arching upward is provided with in the middle part of described electroconductive elastic sheet.

Described electroconductive elastic sheet comprises the conductive metal sheet of several superpositions.

Described main contact and involutory contact are made up of red copper material.

Compared with prior art, the beneficial effects of the utility model are: owing to being conducted electricity by conductive mechanism between fingertip and conductive base, and the resistivity of conductive mechanism is lower, electric current flow to conductive base essentially by conductive mechanism from fingertip, thus the circulation of the effective electric current ensured, and avoid the generation of electric spark, and fingertip is connected by conductive mechanism with conductive base, thus effectively avoid fingertip to offset when generation is rotated, thus precision when effectively raising use.

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, fingertip 12, resetting device 13, described fingertip 12 is connected with resetting device 13, conflict in conductive base 11 side in described fingertip 12 one end, described fingertip 12 is fixedly connected with conductive mechanism 14, described conductive mechanism 14 is connected with conductive base 11, owing to being conducted electricity by conductive mechanism 14 between fingertip 12 and conductive base 11, and the resistivity of conductive mechanism 14 is lower, electric current flow to conductive base 11 essentially by conductive mechanism 14 from fingertip 12, thus the circulation of the effective electric current ensured, and avoid the generation of electric spark, and fingertip 12 is connected by conductive mechanism 14 with conductive base 11, thus effectively avoid fingertip 12 to offset when generation is rotated, thus precision when effectively raising use.

Described conductive mechanism 14 comprises electroconductive elastic sheet 141, connector 142, described electroconductive elastic sheet 141 two ends are fixedly connected on fingertip 12 with on conductive base 11 respectively by connector 142, because electroconductive elastic sheet 141 has good elasticity, thus after fingertip 12 produces rotation, electroconductive elastic sheet 141 carries out elastic deformation, thus can elastic potential energy be added up in electroconductive elastic sheet 141, and fingertip 12 can back promote by the elastic potential energy produced, thus fingertip 12 is improved greatly with the conflict power of involutory contact 2.

Be provided with the portion of arching upward in the middle part of described electroconductive elastic sheet 141, the portion of arching upward is arc-shaped, thus makes the structure of the similar flexural spring of shell fragment, thus improves the elastic force of shell fragment greatly, thus fingertip 12 is improved greatly with the conflict power of involutory contact 2.

Described electroconductive elastic sheet 141 comprises the conductive metal sheet of several superpositions, thus makes each conductive metal sheet independent, and after avoiding overflexing, whole electroconductive elastic sheet 141 produces fracture, thus effectively raises the life-span of use.

Described main contact 1 and involutory contact 2 are made up of red copper material, and it is exactly copper simple substance that red copper has another name called red metal, and conductivity, plasticity are all better, red copper has excellent Dao Re ﹑ ductility and corrosion resistance, what effectively reduces resistance from, also improves heat-sinking capability, effectively raise useful life.

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.
