Abstract
The utility model provides a contactor contact bridge comprising a moving arc angle, a movable contact bridge and contacts. The moving arc angle employs a metal sheet one body integrated structure. The two ends of the metal sheet are bent to form guiding arc angles. The lower side of the moving arc angle clings to the upper side of the movable contact bridge. The contacts are respectively fixedly connected to the two ends of the movable contact bridge. Compared with contactor contact bridges in the prior art, the contactor contact bridge of the utility model adopts the fixed connection of the moving arc angle and movable contact bridge designed in the one body integrated manner, so that the contact bridge is stable in performance, and reliable in quality. The installation of the contactor contact bridge is firm. At the same time, the contact electric resistance is reduced and the welding of the contactor contact bridge is convenient.
Description
Technical field
The utility model relates to a kind of contactor contact bridge, belongs to the technical field that electrical load is controlled.
Background technology
Original A.C. contactor moving contact structure is to adopt gusset piece to add to lead arc angle, at the two ends of gusset piece, also to overlap one and touch bridge, touching bridge embeds and is welded in joint cover, the two ends built-in end that touches bridge is used for welding two contacts, add should weld man-hour and lead arc angle and weld again contact bridge, operation is loaded down with trivial details, the gusset piece both sides do not reach consistent with tactile bridge weld thickness, contact is to touch solder side on bridge uneven and leave gap, solder attachment power is low, and contact resistance is large simultaneously, aggravate contact and conducted the heating in process, easily make contact overheated and burn out, moving contact reduces and causes easily coming off through after lifting repeatedly, leading arc angle solder attachment power on the other hand.The problem that the impacts such as rosin joint, dry joint are used easily appears in too much welding.
Summary of the invention
In order to solve the deficiency of above-mentioned technology, the purpose of this utility model is to provide a kind of contactor contact bridge, its by unique structural design realize stable performance, reliable in quality, installation is firm, contact resistance is little, welds simultaneously convenient.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of contactor contact bridge, it comprises moving arc angle, movable contact bridge and contact, and described moving arc angle adopts sheet metal one-body molded, and the bending of described sheet metal two ends forms leads arc angle, the downside of described moving arc angle is close to the upside of movable contact bridge, and described contact is fixedly connected on respectively movable contact bridge two ends.
As preferably, described moving arc angle downside is provided with round boss.
As preferably, described moving arc angle downside intermediate recess forms slot.
As preferably, described boss and be 4 with the suitable circular hole of boss.
As preferably, the two ends of described moving arc angle upside are provided with the bar shaped boss.
As preferably, described movable contact bridge adopts bridge-type movable contact bridge.
As preferably, between described movable contact bridge and moving arc angle, fix welding.
As preferably, described contact is silver contact.
As preferably, between described contact and movable contact bridge, fix welding.
The utility model compared with prior art, adopts the moving arc angle of one-body molded design to be fixedly connected with the movable contact bridge, makes stable performance, reliable in quality, the installation of contact bridge reduce firmly, simultaneously its contact resistance, convenient welding.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the front view of moving arc angle of the present utility model.
Fig. 3 is the vertical view of moving arc angle of the present utility model.
Fig. 4 is the vertical view of movable contact bridge of the present utility model.
Fig. 5 is the front view of movable contact bridge of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated:
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, the utility model comprises moving arc angle 1, movable contact bridge 2 and contact 3, it is characterized in that: described moving arc angle 1 adopts sheet metal one-body molded, the bending of described sheet metal two ends forms leads arc angle 11, the downside of described moving arc angle 1 is close to the upside of movable contact bridge 2, described contact 3 is fixedly connected on respectively movable contact bridge 2 two ends, moving arc angle 1 adopts integrated mode, by the two ends bending form lead arc angle 11 and realize disconnecting the time extinguishing arc work, and make arc angle 1 directly one-body molded, avoided needing to weld the triviality of leading arc angle 11 in the past, adopt simultaneously welding manner fixing lead arc angle 11, the phenomenon such as easily occur coming off, affect arc quenching effect, and the moving arc angle 1 of employing integral type, avoided leading arc angle 11 due to the phenomenon come off that service time, length may occur.
Described moving arc angle 1 downside is provided with round boss 12, described movable contact bridge 2 upsides are provided with the circular hole 21 suitable with boss 12, described moving arc angle 1 downside intermediate recess forms slot 14, described boss 12 and be 4 with the suitable circular hole 21 of boss 12, described boss 12 is arranged in the bilateral symmetry of slot 14 respectively, fixing welding between described movable contact bridge 2 and moving arc angle 1, by the clamping of circular hole 21 with boss 12, mode by welding is fixed together boss 12 and circular hole 21 again, prevent that it from coming off, simultaneously arc angle 1 and contact bridge 2 are fitted tightly, avoid owing to producing gap, causing the phenomenon of damaging between it.
The two ends of described moving arc angle 1 upside are provided with bar shaped boss 13, while being arranged in contactor, for fixing spring or shell fragment.
Described movable contact bridge 2 adopts bridge-type movable contact bridge, and described contact 3 is silver contact, adopts silver contact to strengthen the frequency of utilization of conductor, has increased the contact effect, has strengthened the performance of conductor, can prevent contact oxidation simultaneously.
As preferably, between described contact 3 and movable contact bridge 2, fix welding, it is fixedly secured on movable contact bridge 2, avoid simultaneously the contact resistance that other connected modes may cause to become large problem.
Embodiment should not be considered as restriction of the present utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection range of the present utility model.
