Description
Technical field
The utility model relates to the component structural of contactor, specifically is meant a kind of contactor fixed contact that improves structure.
Background technology
Contactor mainly is the important power control member that is used to control motor start-stop and other electrical load break-make, the primary structure of existing contactor and basic principle are: relative E shape armature of direction and E shape yoke are installed in its pedestal, be provided with reaction spring between E shape armature and the E shape yoke, be fixedly connected with contact supporting on the E shape armature, be elasticly connected with one or more bridge shape moving contacts on the contact supporting, corresponding being provided with and the corresponding one or more pairs of fixed contacts of bridge shape moving contact in the pedestal, fixed contact links to each other with external circuit, in the middle of E shape yoke, be arranged with coil on the projection, coil links to each other with control end, during use, external connection end inserts motor circuit, control end access control circuit, when coil electricity, E shape armature and E shape yoke be adhesive mutually under magneticaction, and bridge shape moving contact is communicated with a pair of fixed contact, constitute path, make electric motor starting.
The primary structure of above-mentioned fixed contact comprises contact and external connection end two parts, and the two can adopt the moulding of same material integrated punching usually, also can adopt different materials moulding respectively, locks together by screw during installation.Two kinds of structures are arranged in the prior art usually: a kind of is integrated formed structure, and can adopt copper or iron according to the performance requirement difference is material, and the electric conductivity of copper and intensity all are better than iron, if be material all with iron, poor-performing then, if be material with copper all, then cost is higher; Another kind is that external connection end employing iron is material, and it is material that contact part adopts copper, with screw the two is linked together when mounted, though this structure can reduce the use of copper and reduce cost its external connection end poor-performing.
The utility model content
The utility model provides a kind of contactor fixed contact that improves structure, and its main purpose is to overcome existing contactor fixed contact or cost is higher or shortcoming such as poor-performing.
The utility model adopts following technical scheme: a kind of contactor fixed contact that improves structure, comprise the external connection end and the contact platform that are connected with external circuit, the contact platform is provided with and is used for the contact that contacts with moving contact, described contact platform has upper and lower two-layer structure, its upper strata and external connection end are integrally formed, and its lower floor and upper strata fit into one.
Aforementioned a kind of contactor fixed contact that improves structure, the upper strata of its contact platform and external connection end adopt the compression moulding of copper sheet one, and the lower floor of described contact platform is an iron plate.
Described contact platform and external connection end are orthogonal.
Described contact platform is provided with one and is used for being fixed in fixing hole on the contactor by screw, and this fixing hole runs through the upper and lower of contact platform.
Further, the both sides, end of the close external connection end of described contact platform lower floor form two breach, and contact platform upper layer undersurface is provided with two protuberances that cooperate the location with this two breach.
By above-mentioned description to the utility model structure as can be known, compare with prior art, the utlity model has following advantage: one, it is material that the upper strata of contact platform and external connection end all adopt copper, can guarantee that it has excellent conducting performance, contact platform lower floor adopts the iron material thickening, can guarantee to contact platform and have enough intensity, also reduce simultaneously the use amount of copper, saved material cost; Two, the contact platform adopts copper, iron composite double layer structure, helps the electric arc that goes out.
Description of drawings
Fig. 1 is a perspective view of the present utility model;
Fig. 2 is the perspective view of another angle of the utility model.
Embodiment
Embodiment of the present utility model is described with reference to the accompanying drawings.
See figures.1.and.2, this contactor fixed contact comprises external connection end 2 and the contact platform 1 that is connected with external circuit, and contact platform 1 is provided with and is used for the contact 3 that contacts with moving contact.This contact platform 3 has upper strata 11, lower floor's 12 two-layer structures, and its upper strata 11 is integrally formed with external connection end 2, and its lower floor 12 fits into one with upper strata 11.The compression moulding of copper sheet one is adopted with external connection end 2 in the upper strata 11 of this contact platform 1, and the lower floor 12 of this contact platform 1 is an iron plate.
See figures.1.and.2, this contact platform 1 is orthogonal with external connection end 2, and contact platform 1 is provided with one and is used for being fixed in fixing hole 10 on the contactor by screw, and this fixing hole 10 runs through the upper strata 11 and the lower floor 12 of contact platform.
With reference to Fig. 2, platform 1 lower floor 12 in contact forms two breach 121,122 near the both sides, end of external connection end 2, and 11 bottom surfaces, contact platform 1 upper strata are provided with two protuberances 111,112 that cooperate the location with this two breach 121,122.
Because it is material that the upper strata 11 of contact platform 1 and external connection end 2 all adopt copper, can guarantee that it has excellent conducting performance, contact platform 1 lower floor 12 adopts the iron material thickening, can guarantee to contact platform and have enough intensity, also reduce simultaneously the use amount of copper, saved material cost.The experiment proved that contact platform 1 adopts copper, iron composite double layer structure, can play the effect of the electric arc that goes out.
Above-mentioned only is embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection range.
