Description
Technical field
The utility model relates to a kind of protector, particularly a kind of internal structure of current over-load protector.
Background technology
Most protector is applied on the electric tool such as motor, ballast; day by day accurate small and exquisite along with these tool designs; it is more and more less that the structure of protector also designs; Mini-sized protector is little due to volume, is not only conveniently installed to narrow and small position and also can be installed on required product by mosaic mode.The key structure of protector is the installation of temperature-sensing element, and it installs quality and configuration design is related to protector disconnection precision and life-span.
Existing protector all arranges one-in-and-one-out two line conductor, just needs the parallel connection of multiple protector to use, both uneconomically also comparatively to take up room when multiple path uses.
Utility model content
The purpose of this utility model is to provide a kind of Multi-Switch temperature protector that multipath can be provided to protect.
The technical scheme realizing the utility model object is:
A kind of Multi-Switch temperature protector; there is insulating base, movable contact spring, sensing element, static contact group and the base plate for installing insulating seat; above-mentioned static contact group comprises the static contact of 2 ~ 4 apportions; each static contact one end is provided with fixed contact; above-mentioned movable contact spring one end is provided with corresponding moving contact; above-mentioned static contact is arranged in the parallel slot of insulating base respectively, and above-mentioned movable contact spring is fixedly connected with sensing element, base plate.
Above-mentioned movable contact spring is provided with the first corresponding aperture, and sensing element is provided with the second corresponding aperture, and base plate one end is provided with corresponding rivet, and above-mentioned movable contact spring, sensing element and base plate are by rivet, the riveted joint of first and second corresponding aperture.
Above-mentioned base plate is provided with the conical bumps for supporting sensing element.
Above-mentioned base plate is provided with jaw, and above-mentioned insulating base is fixed on base plate by jaw.
Also be provided with the shell being enclosed within protector outside, above-mentioned shell is the semi-surrounding shape of one end open.
Above-mentioned movable contact spring is provided with slot segmentation between moving contact.
Benefit of the present utility model is to be provided with organizes moving contact, fixed contact path more, can control the circuit that multichannel needs protection simultaneously, save protector consumption; This is novel is provided with the reaction sensitivity that conical bumps can strengthen sensing element, and static contact is arranged in insulating base parallel slot, except installing the insulation that can also to ensure firmly between static contact.
Accompanying drawing explanation
Fig. 1 is the exploded perspective view after the utility model removes shell.
Fig. 2 is this novel generalized section when observing from the top down.
Fig. 3 is this novel generalized section when observing from back to front.
Embodiment
See Fig. 1, Fig. 2 and Fig. 3, this novel Multi-Switch temperature protector is provided with two static contacts as required, is respectively first and second static contact 6,8.This is novel also comprises base plate 1, movable contact spring 2, shell 3, sensing element 4, first moving contact 5, first static contact 6, second moving contact 7, second static contact 8, insulating base 9, sealant 10, first wire 11, second wire 12, privates 13 form.First and second moving contact 5,7 above-mentioned is set in parallel in one end of movable contact spring 2, and is provided with slot segmentation 22 between first and second moving contact.
The rivet 13 that above-mentioned base plate 1 one end stretching formation two is hollow, movable contact spring 2 one end have can with the first corresponding aperture 21 of above-mentioned rivets, first and second static contact 6,8 is fixed in the parallel slot 91 of insulating base 9, base plate 1 other end is provided with jaw 11 and is fixedly mounted on base plate by insulating base, and first and second static contact and the fixed contact be located on first and second static contact and first and second moving contact 5,7 are oppositely arranged.Above-mentioned sensing element 4 is disc, one end is provided with the second corresponding aperture 41 for coordinating with the rivet 13 of base plate, above-mentioned movable contact spring 2, sensing element 4 and base plate are riveted together with coordinating of rivet 13 by the first corresponding aperture 21, second corresponding aperture 41, and above-mentioned sensing element 4 is arranged between movable contact spring 2 and base plate 1.
Appeal base plate 1 is also provided with conical bumps 12, and for the strong point of sensing element 4, base plate 1 and first and second static contact 6,8 are connected to the first wire 11, second wire 12, privates 13.This novel outer cover has the shell 3 of one side opening, seals at the peristome sealant 10 of shell 3.
The sensing element 4 of above thermostat is under thermal effect effect, and sudden change upset directly promotes movable contact spring 2 and produces displacement, and first and second moving contact 5,7 is separated with the fixed contact of first and second fixed contact 6,8 simultaneously, thus cuts off circuit loop; After on sensing element, heat leaves; first and second moving contact above-mentioned contacts with fixed contact thus connects circuit loop; this protector realizes cutting off two loops simultaneously; can be used for Y type three phase electric machine as temperature protector; first, second and third wire 11,12,13 of protector connects A/B/C three-phase windings respectively; when after protector action, be separated three-phase windings simultaneously.
Obviously, above-mentioned embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to the utility model execution mode.For those of ordinary skill in the field, can also be easy to make other pro forma change on the basis of the above description or substitute, and these change or substitute and also will be included within protection range that the utility model determines.
