Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As Fig. 1, Fig. 3, Fig. 4, shown in Fig. 6 and Fig. 7, a kind of connection busbar with bridge contact and contact base, it comprises contact base 1, bridge contact 2 and busbar 3, multiple busbar 3 is arranged on a contact base 1, bridge contact 2 is fixed in contact base 1 by busbar 3, bridge contact 2 comprises the identical contact chip group 21 of multiple structure, support 22 and backing plate 23, separated by backing plate 23 between contact chip group 21, contact chip group 21 and backing plate 23 are bolted on support 22, because backing plate 23 is H type, busbar 3 not only contacts with contact chip, also contact with the intermediate transverse girder of backing plate 23, enlarge active surface thus.Each contact chip group 21 comprises symmetrically arranged, the first contact chip 211 and the second contact chip 212 do not contacted with each other, first, second contact chip to comprise respectively and fits tightly, the middle two panels contact chip forming space 213, spring 214 two ends are each passed through first, the space 213 of the second contact chip, be fixed in the middle of contact chip group 21 by rivet 215, the crossbeam spacer spring 214 of backing plate 23, described contact chip comprises the first bending part 216, second bending part 218 and with first, the line part 217 that second bending part 218 connects, described support 22 also comprises and is placed in the middle of contact chip group 21, for making the baffle plate 221 of contact chip group 21 proper alignment, this baffle plate 221 and first, second contact chip line part 217 spacing distance is wide, when assembling, first bending part 216 of contact chip group 21 is bolted, prevent contact chip upper and lower displacement, while rivet 215 fixing spring 214, also Restricted Contact sheet produces the displacement in outside mutually, the baffle plate 221 of abutting contact sheet line part 217 is increased in the middle of contact chip group 21, can the displacement of Restricted Contact sheet mutually inner side further, by the position of 3 fixed contact piece groups 21, make it can not move in running, further ensure that the contact of contact chip group 21 and busbar 3, thus effectively reduce caloric value, reach the object reducing temperature rise.
As shown in Figure 5, described support 22 is the integral structure through being stamped to form, and simplifies technique, convenient.
As shown in Figure 2, described busbar 3 comprise first connecting portion 31 suitable with bridge contact 2, with the first connecting portion 31 perpendicular the second connecting portion 32 and be symmetricly set on the fixture 33 of the first connecting portion 31 both sides, first connecting portion 31 is bolted with fixture 33, and busbar 3 is arranged on contact base by fixture 33.Described support 22 also comprises the protuberance 222 being placed in baffle plate 221 two ends, and this protuberance 222 produces displacement for limiting after the first connecting portion 31 agrees with bridge contact 2 in bridge contact 2, thus the contact area of both impacts.
As shown in Figure 3, the lower end of the first connecting portion 31 is provided with for the muscle 311 with bridge contact 2 clamping, this muscle 311 forms snap-fit engagement with the first bending part 216 of contact chip, thus busbar 3 is not departed from from bridge contact 2, with electrical connection normal both ensureing, during installation, by spring 214, first bending part 216 of bridge contact 2 is separated from each other, second bending part 218 is close to each other, enter in bridge contact 2 smoothly to make the muscle 311 of busbar 3, then utilize the restoring force of spring 214, make the range recovery initial condition between distance between the first bending part 216 and the second bending part 218, so namely block bridge contact 2 by muscle 311.
