Description
Technical field
The utility model relates to the accessory in the A.C. contactor, moving contact especially wherein.
Background technology
Original A.C. contactor moving contact structure is to adopt gusset piece to add to lead arc angle, also to overlap one at the two ends of gusset piece and touch bridge, touch bridge and embed also and be welded in the gusset piece, the both sides built-in end that touches bridge is used for welding two contacts, adds namely will weld man-hour to lead arc angle and weld again contact bridge.The defective that said structure exists is that welding is loaded down with trivial details, the gusset piece both sides do not reach consistent with tactile bridge weld thickness, the contact is to touch solder side on the bridge uneven and leave the slit, solder attachment power is low and contact resistance is large, and moving contact reduces and causes easily coming off through leading arc angle solder attachment power power after the lifting repeatedly.
Summary of the invention
The defective that exists in order to overcome above-mentioned existing A.C. contactor moving contact, the utility model provides stable performance, reliable in quality, installation is firm, contact resistance is little, the more convenient reliable A.C. contactor moving contact of welding.
The A.C. contactor moving contact technical scheme that the utility model provides is: comprise an integrated touch panel, the relative both sides of touch panel are equipped with leads arc angle and contact, the two sides that arc angle is symmetrically distributed in touch panel are led in both sides, the contact, both sides is symmetrically welded the bottom surface in touch panel, both sides are led arc angle and are had respectively the contact-making surface that fits with both sides touch panel side profile, and wherein every side is led terminal and center, the two ends of arc angle and is separately fixed on the touch panel.
The advantage of technique scheme is:
(1), touch panel adopts integral type to make the contact welding convenient firmly, reduce the welding expense, integrated tactile bridge can avoid the gusset piece of original split-type structural and touch panel when solder contacts, can't avoid producing the slit between contact and the gusset piece, can make contact resistance higher, cause the terminals temperature rise and damage product, the contact resistance of integral structure is low also more stable, can effectively avoid temperature rise, thereby make the product operation more reliable;
(2), lead the combination of arc angle and touch panel tightr, each is led arc angle and all can firmly link together by three fixing points on the contact-making surface of fitting with the touch panel side and touch panel, eliminate the hidden danger of quality that gets loose and cause because of between the two connection, prolong its useful life.
The A.C. contactor moving contact that the utility model provides improves technical scheme: the two ends end that every side is led arc angle all has fluting, fluting top has lower pressure surface and double wedge, lower pressure surface and touch panel end face are positioned at the plane of same level direction, double wedge is outstanding the setting downwards, slotted lower portion has upper pressure surface, upper pressure surface intersects for the inclined-plane that relatively presses down face tilt and with lower pressure surface, touch panel has with to lead the ridge that arc angle fluting profile fits prominent, and this ridge is prominent to have the teeth groove that opening upwards cooperates with the double wedge butt, the upper end face that cooperates with lower pressure surface butt and the lower end face that cooperates with upper pressure surface butt.Lead prominent the two shape of arc angle fluting and touch panel ridge and passed through special design, lead arc angle fluting interlock and be embedded into the touch panel ridge prominent among, the touch panel ridge is prominent to be held on firmly and to be led among arc angle slots, and makes to connect fasteningly between the two, is difficult for getting loose.
The A.C. contactor moving contact that the utility model provides further improves technical scheme: the contact-making surface bottom of leading arc angle aligns with touch panel side lower edge, and the contact has the outer rim that contacts simultaneously touch panel side lower edge and lead arc angle contact-making surface bottom.The benefit that such structure is brought is when when welding solder melts, with contact outer rim, touch panel side lower edge and lead three confluce, arc angle contact-making surface bottom and stick together, makes whole connection more closely and firmly.
Below in conjunction with drawings and Examples the utility model is described in further detail.
