Embodiment
Contact part 14,16 has the equivalent structure of being made by the aluminum plate bar, preferably forms by extruding, and accepts nickel or money base surface treatment.
The contact part 14,16 of each square-section comprises the serrate profile contact surface of an obvious evagination separately, on the stage casing, inside between a retainer 24,25 and the short column 26,27, a discharger of two short columns formation left side contact part 14 contacts a back discharge device of part 16 with the right.The fore-end of short column 26,27 tops by an insulating material-such as polyamide-based-block 28 made covers, it is as the quick engaging means at the jockey input end.The inner surface of two blocks 28 is with respect to vertically tilting, so that constitute a convergent mouth at the input end of jockey 10.
Be used for many serrations on the contact surface 22 that rated current flows can promote electric contact and reduce shape be fuse 12 a blade terminals 29 insertion and extract strength out.The convex shape of two contact surfaces 22 makes that may dissolve terminals 29 aligns error with respect to anchor clamps 10 any.
The outer surface of each contact part 14,16 is furnished with a series of radiating fins 30, extend in the opposite of short column 26,27, in the terminal spring silk end of 28 and two contact pressure springs 34 of block to the end put between wherein the groove 32.Each spring-like is a U word, and the end has the termination of two bendings and forms a carriage.This existence to spring has guaranteed the even distribution of anchor clamps 10 contact pressures on the terminals 29 that are in the insertion position.
The rear portion of each contact part 14,16 is furnished with the bottom of obvious bending and has the eyelet that gets out, and is screwed at least one screw 38 among the latter, makes contact part 14,16 may be fitted on the security strip 18 of conductor 20.One compression spring 40 is interposed between lath 18 and each screw 18 heads, inserts or allow when withdrawing from terminals 29 separating action slightly of contact part 14,16 with box lunch.Each retainer 24,25 of closing can prevent to contact part 14,16 and move towards each other and keep a lateral clearance 42 all the time between short column 26,27 at anchor clamps 10 set terminals.
The short column 26 that constitutes the discharger on the left side contact part 14 is by in order to prevent that the copper or the tellurium copper alloy that produce welding from making.Another short column 27 of back discharge device (backdischarger) that constitutes the second contact part 16 is preferably by insulating material, makes such as polyamide, rises on the short column 26 of arcing contact so that all the time starting the arc zone is passed as the discharger fingertip.Obviously, short column 27 also can conduct electricity as short column 26.
The operation of jockey 10 that meets Fig. 1 to 4 is as follows:
Be shown in anchor clamps 10 among Fig. 1 to 4 not on the bonding station, the distance between the short column 26,27 is less than the thickness of terminals 29 and less than the gap that is configured between two contact surfaces 22.Described closing to spring 34 and retainer 24,25 can keep two contact surfaces 22 parallel to each other significantly and perpendicular to security strip 18. Short column 26,27 keeps extending all the time with respect to the convergent mouth of each block 28.
On bonding station (Fig. 3), the terminals 29 of fuse 12 insert between two contact surfaces 22, and the described even distribution of spring 34 being guaranteed contact pressure.The mechanism that terminals produced in 29 insertion stages cause contacting part 14,16 pivot in opposite direction on the security strip 18 of conductor 20 with each bottom 36 after generation separating action slightly.The electric current of fuse 12 is divided into two strands in contact part 14,16, and corresponding Joule effect is eliminated by each radiating fin 30.Make and when charged, to connect fast that electric arc only occurs between short column 26 and the terminals 29 and do not move to aluminium matter and contact on the part 14,16 in the existence of anchor clamps 10 each insulating cap 28 of set terminal place.
Extract when changing an impaired fuse when being engaged in significantly, take off terminals 29 along arrow F direction (Fig. 3) and can cause each contact surface 22 1 to move toward each other when terminals 29 leave short column 26,27.If chargedly be engaged in operation, electric arc only is formed on as on the short column 26 that plays arcing contact.
Fig. 5 and 6 shows a kind of anchor clamps 100 that have a plurality of contacts, and wherein each contact part 114,116 is divided into two adjacent part 114a, 114b; 116a, 116b are separated each other by a gap 142 of extending perpendicular to gap 42.Obviously, contact part 114,116 can depend on the rated power of equipment and the maximum temperature rise of allowing and be divided into three or four parts that are equal to.
