Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
Composition graphs is known, a kind of probe of contactor mechanism, comprise fixed contact 1, moving contact 2 and moving contact support 3, described moving contact 2 is provided with moving contact 21, the thickness of described moving contact 21 near the side of moving contact support 3 is less than thickness as outside, the moving contact 21 of the thicker side of arc loss produced when contactor runs, moving contact consumption rate is average, extend the service time of contactor, described fixed contact 1 is positioned at correspondence position below moving contact 2, fixed contact 1 is provided with fixed contact 11, the lower surface of moving contact 21 is parallel with the upper surface of fixed contact 11 makes moving contact 21, it is face contact when fixed contact 11 contacts, dynamic/static contact contact better effects if, the electric arc produced when simultaneously making dynamic/static contact be separated is less, and move from the inside to the outside, the moving contact of the thicker side of loss, the operating time of contactor is longer.
Composition graphs three is known, and fixed contact 1 is parallel with the lower surface of moving contact 21 for the upper surface installing fixed contact 11, namely fixed contact 1 upper surface tilt or fixed contact integral inclined, be arranged on the consistency of thickness of the fixed contact 11 on fixed contact, save fixed contact material.
Through long-term use experience, when the lower surface of described moving contact 21 and the angle of horizontal plane are 3 degree, arc loss moving contact is average, because fixed contact 1 is parallel with the lower surface of moving contact 21 for the upper surface installing fixed contact 11, so fixed contact 1 upper surface tilts or the integral inclined angle of fixed contact is 3 degree.
Described moving contact 2 comprises copper guide card 22, described moving contact 21 is located on copper guide card 22, described moving contact support 3 is provided with moving contact erecting bed 31, described copper guide card 22 is provided with boss 221, moving contact 21 is connected with copper guide card 22 by boss 221, described moving contact erecting bed 31 is provided with the square hole 311 passed for boss 221, boss on moving contact and copper guide card welds together, because the contact-making surface of moving contact and copper guide card is larger, and the resistance of copper guide card is lower, then temperature rise is lower, can not scorification copper guide card, safe and reliable; Copper guide card is built in moving contact erecting bed simultaneously, enhances the magnetic field of contact mechanism, striking better effects if.
Described moving contact 21 is silver contact, and described fixed contact 11 is silver contact, can strengthen the conductivity of contact system, prevent contact to be oxidized simultaneously.The AgSnO2(9 that described moving contact 21 adopts Fuda Alloy Material Co., Ltd to produce) In2O3(4)-T(I.O) material, this material arc resistance can be better, but temperature rise is higher, cost is high, the AgCdO(15 that described fixed contact 11 adopts Fuda Alloy Material Co., Ltd to produce) material, this material temperature rise is lower, cost is lower, relative resistance to electric arc shape can be lower, due to dynamic/static contact be separated time, electric arc is lower to moving contact damage, therefore the material of moving contact is arc resistance energy AgSnO2(9 preferably) In2O3(4)-T(I.O), simultaneously, consider that the temperature rise of contactor can not be too high, so the material of the fixed contact AgCdO(15 that to be temperature rise lower).
A kind of A.C. contactor, comprise top cover 4, relaying shell 5, electromagnetic system 6 and base 7, described relaying shell 5 is arranged on base 7, described electromagnetic system comprises dynamic iron core 61 and static iron core 62, described static iron core 62 is arranged in base 7, described dynamic iron core 61 is provided with dynamic iron core mount pad 63, also comprise described probe of contactor mechanism, described moving contact support 3 is arranged with vertical part 32, described vertical part 32 is arranged on dynamic iron core mount pad 63, described vertical part 32 is provided with vertical projection 321, described vertical projection 321 is provided with vertical guide 322, described relaying shell 5 is provided with the vertical groove 51 corresponding with vertical guide 322 and the transverse concave groove 52 for blocking vertical guide 322.When the coil is energized, static iron core produces electromagnetic attraction, will move iron core adhesive, because dynamic iron core is arranged in dynamic iron core mount pad, the vertical part that moving contact is supported is connected with dynamic iron core mount pad, therefore be arranged on moving contact in moving contact support to contact with fixed contact, the closing of contact, thus switch on power, because vertical guide is fixed on relaying shell, vertical projection on vertical part coordinates with vertical guide, ensures that moving contact can straight down, accurately contact closed with fixed contact.
Described moving contact support 3 is provided with limit shaft 33, and described limit shaft 33 has pressure strip 34, and described pressure strip 34 is between copper guide card 22 and limit shaft 33, due to the effect of pressure strip, cunning can not be gone up when moving contact contacts with fixed contact, can tight closure together, ensure electric current unobstructed.
