Description
Technical field
The utility model relates to a kind of probe of contactor, belongs to the technical field of electrical load control.
Background technology
For improving the electric conductivity between the contactor dynamic/static contact, in the relevant position of contact silver contact is set usually.But in the prior art many with the silver contact physical bond on rivet, on the copper guide card of contact, offer through hole again, rivet is realized being connected of silver contact and copper guide card in the through hole of copper guide card, operation is more.This structure increased the resistance between silver contact and copper guide card, aggravated contact and conducted heating in the process, causes silver contact overheated and burn out easily; Riveted structure between rivet and the copper guide card on the other hand, in use because the loosening of rivet takes place in the adhesive of dynamic/static contact easily, caused the decline of contact on-off function, in use also caused coming off of silver contact easily simultaneously, made contact lose on-off function.
The area of section of rivet is too small with respect to the width of copper guide card in the prior art, has limited the size of silver contact, thereby has increased the unit are electric current of silver contact when the dynamic/static contact adhesive, the temperature rise that has increased silver contact; Simultaneously, also increased the electric arc at the silver contact place of contact, the disjunction but also can make contact burning reliably in time that this had not only hindered circuit has influenced the useful life of contactor.
The utility model content
The utility model main purpose is to provide a kind of operation less, production cost is lower, silver contact combines reliably with the copper guide card, caloric value is little, the well behaved probe of contactor of break-make, and fixedly the existing operation of silver contact is more to have solved rivet, production cost is higher, caloric value is bigger, and silver contact comes off easily, problems such as break-make poor-performing.
Another purpose of the present utility model is to provide a kind of temperature rise lower, the probe of contactor that useful life is long, solved that to touch the too small temperature rise that causes of platform sectional area in the prior art too high, electric arc had greatly not only hindered the disjunction but also can make contact burning reliably in time of circuit, had influenced the problems such as useful life of contactor.
Above-mentioned technical purpose of the present utility model solves by the following technical programs: comprise copper guide card and silver contact, described copper guide card is provided with the integrated with it platform that touches, and described silver contact is arranged on and touches on the platform.To touch platform and the copper guide card is one-body molded, reduce the processing and the assembly process of contact, reduce manufacturing cost, improve production efficiency, eliminate the resistance that the riveted joint of rivet and copper guide card exists, reduce the caloric value at silver contact place, reduce temperature rise; Silver contact is set directly at the copper guide card is integrated touches on the platform, can make to combine more firmly between silver contact and the copper guide card, improved the break-make performance of contact.Boss on the copper guide card both can adopt punch forming, also can adopt to be cast into moulding.
As preferably, described copper guide card is provided with and touches the platform corresponding grooves corresponding to the another side that touches the platform position.The mode that adopts punching press is in the punching press of copper guide card, an evagination of copper guide card forms and touches platform, the then corresponding indent of another side forms groove, thereby touch the area of dissipation that platform and groove have increased silver point, strengthened radiating effect, the heat that silver contact is produced can be distributed apace, has reduced temperature rise, prevent burning out of silver contact, prolonged useful life.
As preferably, the degree of depth of described groove is the 1/3-2/3 of copper guide card thickness, and the degree of depth of described height that touches platform and groove is suitable, has both guaranteed to touch the bonding strength of platform and copper guide card, makes silver contact obtain enough big area of dissipation again.
As preferably, described copper guide card is provided with several integrated with it location conducting boss, and described copper guide card is provided with and locatees the conducting boss corresponding concave part corresponding to the another side of location conducting boss.Can realize the location and the conducting function of copper guide card and binding post, reinforced conductive effect by the location conducting boss.
As preferably, described location conducting boss and touch two facing surfaces that platform lays respectively at the copper guide card.Make the installation site of silver contact and copper guide card lay respectively at not coplanar, both stagger, and are convenient to install and assembling.
As preferably, described to touch platform be Rotary-table so that processing and manufacturing, and its diameter is slightly less than the width of copper guide card; The described diameter that touches platform is the 2/3-5/6 of copper guide card width.Enlarged the sectional area that touches platform, make silver contact that bigger contact area be arranged with it, prevent to come off, increase the area that passes through of electric current simultaneously, reduced the electric current that passes through of unit are, reduced temperature rise, also reduced electric arc, make and circuit break-make in time improved the break-make performance, prolonged useful life.
Characteristics such as therefore, it is less to the utlity model has operation, and production cost is lower, and silver contact combines reliably with the copper guide card, and caloric value is little, and break-make is functional, and temperature rise is lower, and useful life is long.
