Embodiment
Embodiment: as Fig. 1, Fig. 2, Fig. 3, shown in Figure 6, a kind of large-current elastic contact terminal of irregularly-arrayed multiple contact, the butt end, butt end of this contact terminal includes six contact chips 111,112,113,114,115 and 116, and each contact chip is provided with corresponding contact zone 1111,1121,1131,1141,1151 and 1161.On a face and b face that above-mentioned contact chip is interspersed at contact, contact chip 111,114 and 115 wherein is isometric when blanking, be defined as long contact chip, its contact zone correspondence is defined as long contact zone, contact chip 112,113 and 116 is isometric when blanking, is defined as the short circuit contact, and its contact zone correspondence is defined as the short contact district, gap between the length contact chip is d, with reference to figure 6.After the panel beating moulding, long contact chip 111,114,115 all becomes " product " type to arrange with short circuit contact 112,113,116, two " product " type cross-distribution, long contact zone and short contact district form irregular and the multiple zone that contacts, the gap in long contact zone and short contact district is D (D can equal d), with reference to figure 3.
As shown in Figure 7, in the docking operation, because there are diversity distance D in long contact zone and short contact district, so at first producing strain and inserting in the chip-type contact 20 is long contact chip 111,114 and 115, when its insertion depth during near D, short circuit contact 112,113 and 116 just touches chip-type contact 20 and produces strain under to the effect of relay and finishes and insert and butt joint.Since the utility model structure will be in the past contact chip when butt joint the mode of concentrated distortion by irregular arrangement be divided in time before and after twice (or repeatedly) deformed movement, thereby can effectively reduce total insertion force and make whole docking operation easily soft.
Large-current elastic contact terminal in irregularly-arrayed multiple contact of the present utility model has at least 4 contact zones (this preferred embodiment is 6), these contact zones 1111,1121,1131,1141,1151 and 1161 etc. separate, each contact zone spatially with each adjacent contact district in certain distance that all staggers.This separate contact zone has guaranteed that contact contacts, increased contact-making surface at the multiple spot that plugs together after putting in place, reaches the purpose of reliable contact; On the other hand, this stagger mutually and independently the contact zone disperseed when butt joint because of transmitting the heat that big electric current produces, be beneficial to heat radiation and control temperature rise, improve current capacity and reliability.
Also be provided with the hangnail structure 117,118 of the location that is used on insulating base on the contact terminal.
Should be pointed out that for the utility model also to have the embodiment of multiple conversion and remodeling, be not limited to the specific embodiment of above-mentioned execution mode through proving absolutely.The foregoing description is as just explanation of the present utility model, rather than to restriction of the present utility model.In a word, protection range of the present utility model should comprise those conspicuous to those skilled in the art conversion or substitute and remodeling.
