Description
Technical field
The utility model relates to contact technical fields, and in particular to a kind of good contact of contact performance.
Background technique
Contact is one of critical component of device for switching, the main performance of device for switching and the length in service life, in very great Cheng
The quality of contact material is depended on degree.Contact material is usually required that with good electric conductivity, lower contact resistance, higher
Resistance fusion welding energy, higher resistance to arc erosion energy and anti-material transfer ability vacuum contact material is also required to shut off
It is worth that small, compressive resistance is high and breaking capacity is high.
Contact is generally divided into movable contact and stationary contact, and the contact or disengaging of dynamic and static contact can be realized the connection of circuit
Or disjunction.But the way of contact of traditional moving contact and static contact is the way of contact used between cambered surface point, it is such to connect
Touching mode contact area is little, and passes through long-term use, it is more likely that and it will lead to contact top surface and ablation or dust fall occur,
It is easy to produce disruption, so as to cause poor contact between the contact point in switch.
Utility model content

Point.
For this purpose, the utility model uses following technical scheme: a kind of good contact of contact performance, including conduction
Body and connector；
The electric conductor is set to the top of the connector；
The section of the electric conductor is made of the closed figure that round wires and bonding wire are surrounded, and the electric conductor is described cuts
The stereoeffect that face is formed along the longitudinal stretching perpendicular to section.
Preferably, the connector includes cradle and mounting base；
The cradle is set to the top of the mounting base；The left and right sides of the cradle are arranged to cambered surface, and
The front and rear sides face of the cradle is arranged to plane；
The mounting base is cylindrical body.
Preferably, the material of the electric conductor is silver alloy, and the material of the connector is copper.
Preferably, the radius of the round wires in the section of the electric conductor is 1-6mm.
Preferably, the diameter range of the left and right sides of the cradle is 1-5mm.
Preferably, the altitude range of the top of the electric conductor to its bottom is 0.1-0.5mm.
Preferably, the bonding wire is one of straight line, circular arc line, wave, jaggies.
Preferably, the diameter range of the mounting base is 1-4mm.
The utility model has the beneficial effects that point contact of the contact point of dynamic and static contact by original arc surface and arc surface
It is changed to contact of the straight line with straight line, to increase contact area between the two, enables the contact performance between dynamic and static contact good
It is good, the phenomenon that having achieved the purpose that improve contact performance, prevented poor contact and cause contact failure.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the schematic diagram in the contact complete section section of one of embodiment of the utility model；
Fig. 2 is the main view of one of embodiment of the utility model；
Fig. 3 is the left view of one of embodiment of the utility model；
Fig. 4 is the top view of one of embodiment of the utility model.
Wherein: electric conductor 1, round wires 11, bonding wire 12, connector 2, cradle 21, mounting base 22.
Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
A kind of good contact of contact performance, including electric conductor 1 and connector 2；
The electric conductor 1 is set to the top of the connector 2；
The section of the electric conductor 1 is made of the closed figure that round wires 11 and bonding wire 12 are surrounded, and the electric conductor 1 is
The stereoeffect that the section is formed along the longitudinal stretching perpendicular to section.
The top highest point of the contact is straight line so that the contact point of dynamic and static contact by original arc surface with
The point contact of arc surface is changed to contact of the straight line with straight line, to increase contact area between the two, enable dynamic and static contact it
Between contact performance it is good, achieved the purpose that the phenomenon that improving contact performance, preventing poor contact and cause contact failure.And
And test proves that, even if somewhere dust fall on electric conductor 1, does not interfere the contact in other places yet, guarantee energy between dynamic and static contact
It is enough smoothly to connect circuit.
Further, the connector 2 includes cradle 21 and mounting base 22；
The cradle 21 is set to the top of the mounting base 22；The left and right sides of the cradle 21 are arranged to arc
The front and rear sides face in face, the cradle 22 is arranged to plane；
The mounting base 22 is cylindrical body.
As shown, the cradle 21 is for electric conductor 1 described in support.The left and right directions for defining the cradle 21 is
Transverse direction, the front-rear direction for defining the cradle 21 is longitudinal direction.The transverse width of the cradle 21 is greater than described
The transverse width of electric conductor 1 enables the cradle 21 state electric conductor 1 convenient for support residence, and the top of the electric conductor 1
Cambered surface also can continue to seamlessly transit along the left and right sides of the cradle 21, conducive to the generation for reducing burr.And it is described
The front and rear sides face of cradle 21 is arranged to plane, and when subsequent installation is then convenient for people's stabilization clamp to handle contact.
Further, the material of the electric conductor 1 is silver alloy, and the material of the connector 2 is copper.
Because the position contacted at first first between contact is between electric conductor 1 and electric conductor 1, both is allowed
Between resistance it is as small as possible, facilitate the conducting between contact.The material of the electric conductor 1 be silver alloy, specially AgNi10,
The resistance value very little of the material.And the above-mentioned setting of contact, contact can be allowed to play the role of current segmenting, be to pass through electricity
After hindering smaller silver alloy connection circuit, electric current transmission is then carried out by copper product, this is conducive to save production cost, and will not
Weaken the working performance of contact.
Further, the radius of the round wires in the section of the electric conductor 1 is 1-6mm.
Cambered surface at the top of contact is wide, conducive to the contact conducting between contact.
Further, the diameter range of the left and right sides of the cradle 21 is 1-5mm.
The wider width of the cradle 21, is conducive to be used as intermediate, is on the one hand conducive to support residence and states electric conductor 1,
On the other hand it is conducive to it and the mounting base 22 connects.
Further, the altitude range of top to its bottom of the electric conductor 1 is 0.1-0.5mm.
Guarantee the thickness of the electric conductor 1, conducive to the mutual energization between contact.
Further, the bonding wire 12 is one of straight line, circular arc line, wave, jaggies.
Further, the diameter range of the mounting base 22 is 1-4mm.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as
