Abstract
A novel secondary contact set of a breaker comprises a moving conducting rod, a static conducting rod and one-piece contact sheet, wherein the upper end of the one-piece contact sheet has a multi-piece opening structure, the lower end of the one-piece contact sheet has a planar structure, the lower end of the moving conducting rod extends into the multi-piece opening structure, and the upper end of the static conducting rod is in connection with the planar structure in surface contact manner. The novel secondary contact set is low in temperature rise, simple in structure, easy for assembly and low in cost.
Description
Technical field
The utility model belongs to low tension switch technical field, especially relates to a kind of circuit breaker secondary contact group.
Background technology
In low voltage electrical apparatus industry, existing circuit breaker secondary contact group is all that the contact of contact knife type is assembled and contacted two kinds of structures with chip,
For traditional contact knife type contact group, its complex structure, corresponding kit is more, and assembling is complicated; Cause waste artificial, material, cost is higher.
The contact group of existing chip package assembly, because active face and stationary plane are all Multi-contact, contact is counted more, and relative contact is long-pending also can be larger, the temperature rise control producing while being conducive to the operation of product normal full load.But stationary end is owing to not needing activity, though Multi-contact contact area is larger, still can cause the temperature rise of contact point.
Summary of the invention
In order to overcome the complex structure of existing circuit breaker secondary contact group, the deficiency that assembling is complicated, cost is higher, the utility model provide a kind of temperature rise lower, simple in structure, assemble simple, lower-cost novel breaker secondary contact group.
The utility model for the technical scheme providing is provided is:
A kind of novel breaker secondary contact group, comprise moving conductive rod, static conductive rod and integral type contact, described integral type contact upper end is multiple-piece hatch frame, described integral type contact lower end is planar structure, the lower end of described moving conductive rod is stretched in described multiple-piece hatch frame, and the upper end of described static conductive rod is connected with described planar structure face contact type.
Further, described integral type contact upper end multi-disc opening and lower transverse plane are integrated.
Described multiple-piece hatch frame is provided with the boss towards inner chamber, and the bottom of described moving conductive rod is provided with annular pitting area, and described boss is stuck in described annular pitting area.
Further again, the multiple-piece hatch frame place outside described boss is provided with spring spacing edge-cut, and install and tightens up spring at described spring spacing edge-cut place.
The center of described planar structure has installing hole, and the upper end of described static conductive rod has lower installing hole, and securing member is arranged in described upper installing hole, lower installing hole from top to bottom.
The beneficial effects of the utility model are:
(1) adopt the utility model novel breaker secondary contact group, owing to being integral structure, save loaded down with trivial details assembling process, there is higher production efficiency, thereby cost is lower.
(2) the utility model novel breaker secondary contact group, it is that plane is fixedly connected with static conductive rod joint face, makes contact area larger, contact is also larger, substantially can ignore the problem of temperature rise of stationary end, has market application foreground widely.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Referring to figs. 1 through Fig. 6, a kind of novel breaker secondary contact group, comprise moving conductive rod 1, static conductive rod 5 and integral type contact 3, described integral type contact 3 upper ends are multiple-piece hatch frame 6, described integral type contact lower end is planar structure 7, the lower end of described moving conductive rod 1 is stretched in described multiple-piece hatch frame 6, and the upper end of described static conductive rod 5 is connected with described planar structure 7 face contact types.
Further, described integral type contact upper end multi-disc opening and lower transverse plane are integrated.
Described multiple-piece hatch frame 6 is provided with the boss 9 towards inner chamber, and the bottom of described moving conductive rod 1 is provided with annular pitting area 10, and described boss 9 is stuck in described annular pitting area 10.
Further again, the multiple-piece hatch frame place outside described boss 9 is provided with spring spacing edge-cut, and install and tightens up spring 2 at described spring spacing edge-cut place.
The center of described planar structure 7 has installing hole, and the upper end of described static conductive rod 5 has lower installing hole, and securing member 4 is arranged in described upper installing hole, lower installing hole from top to bottom.
In the present embodiment, by tightening up spring 2, integral type contact 3 upper ends are shunk toward center, depression position 10 close contacts of contact upper end boss 9 and moving conductive rod obtain good Multi-contact performance; Described integral type contact 3 lower ends are planar structure 7, are fixedly connected with static conductive rod 5 by securing member 4; The described spring 2 that tightens up is for to connect into circle by extension spring two ends, and composition circular ring type tightens up spring.
Be more than concrete exemplary applications of the present utility model, protection range of the present utility model is not constituted any limitation.The technical scheme forming is replaced in all employing equivalents or equivalence, within all dropping on the utility model rights protection scope.
