Abstract
The utility model relates to a coil rack of an electromagnetic relay, comprising a coil rack body, wherein an inner hole for installing an iron core is arranged in the coil rack body, at least two positioning convex ribs are arranged on the inner wall of the inner hole, a cavity for positioning and installing the iron core is arranged among the end surfaces of the positioning convex ribs, and the cavity is in interference fit with the iron core. Compared with the prior art, the inner hole is internally provided with the convex ribs to be in interference fit with the iron core, so that the coil disconnexion and the product abandonment caused by the expansion of the coil rack can be effectively avoided; and by adopting the interference fit, the iron core is reliably positioned, and the riveting intensity of the iron core and the bad stability of an iron core section can be improved.
Description
Technical field
The utility model relates to a kind of electromagnetic relay technical field, is specifically related to a kind of improvement structure of electromagnetic relay coil frame.
Background technology
Usually, the bobbin of electromagnetic relay is provided with the endoporus that is used to install iron core, and the surface of this endoporus is an even surface; In order to realize the fixing and location of iron core, bobbin and iron core adopt interference fit, but after should cooperating the lower coil frame to expand; Cause coil breakage easily; Product rejection, and cause the variation that insulate between the coil inside enamelled wire easily, Product Safety reduces greatly; In order to address the above problem; Someone adopts matched in clearance with bobbin and iron core, though this has solved because of after the coil expansion problem of insulating properties variation between coil breakage and the coil inside enamelled wire; But when iron core is riveted; This cooperation is prone to cause the iron core position deviation, causes iron core intensity and core packet difference unstable, and production property and stability reduce.
Summary of the invention
To the deficiency that prior art exists, the purpose of the utility model is to provide a kind of convex tendon that is provided with on the bobbin endoporus with the iron core interference fit that adopts, and can keep coil characteristics, can guarantee the bobbin of electromagnetic relay of the accurate positioning of iron core again.
For realizing above-mentioned purpose; The utility model provides following technical scheme: a kind of bobbin of electromagnetic relay; Comprise the bobbin body, it is provided with the endoporus that supplies iron core to install, and it is characterized in that: the inwall of said endoporus is provided with at least 2 location convex tendons; Form cavity, this cavity and the iron core interference fit that supplies the iron core location and installation between the said end face of respectively locating convex tendon.
Through adopting technique scheme; Adopt convex tendon and iron core interference fit, effectively avoided the expansion of the bobbin of electromagnetic relay, thereby well kept coil characteristics; And pass through interference fit; Can well locate iron core, improve the iron core riveting intensity and stablize, enhance product performance and the productibility of product with the core packet difference.
The utility model further is set to: the inwall of described endoporus is provided with 3 location convex tendons, and respectively locatees between convex tendon and be equally spaced.
Through adopting technique scheme, locate convex tendon and iron core interference fit for 3, iron core is located reliable and the location convex tendon is provided with conveniently.
The utility model further is set to: the surface of described convex tendon is a circular arc.
Through adopting technique scheme, the convex tendon of arcuate surface and iron core are fitted more reliable, have further increased the reliable location of iron core.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the bobbin and the iron core constitutional diagram of the utility model;
Fig. 2 is the bobbin upward view of the utility model.
Embodiment
Referring to accompanying drawing 1, accompanying drawing 2; The bobbin of the disclosed a kind of electromagnetic relay of the utility model; Include bobbin body 1, it is provided with the endoporus 12 that supplies iron core 2 to install, and the inwall of said endoporus 12 is provided with at least 2 location convex tendons 13; Form cavity, this cavity and iron core 2 interference fit that supply iron core 2 location and installation between the said end face of respectively locating convex tendon 13.Under this structural design; The location convex tendon 13 that the inwall of endoporus 12 is provided with can be 2,3,4 etc.; But no matter locate convex tendon 13 is more than 2 or 2; Each end face of locating convex tendon 13 can form a cavity that iron core 2 can accurately be located all the time, and promptly iron core 2 contacts with the end face of location convex tendon 13, and the location.
Be provided with conveniently in order to make iron core 2 accurate positioning in endoporus 12 reliably reach location convex tendon 13, the inwall that present embodiment is employed in endoporus 12 is provided with 3 location convex tendons 13, and respectively locatees 13 of convex tendons and be equally spaced.Certainly when location convex tendon 13 be 3 when above, the utility model is preferential to be adopted and locatees 13 of convex tendons and be equally spaced.
Cooperate reliably between iron core 2 and the convex tendon 13 in order to make, the surface of said convex tendon 13 is a circular arc.
Claims (3)
1. the bobbin of an electromagnetic relay; Comprise the bobbin body; It is provided with the endoporus that supplies iron core to install; It is characterized in that: the inwall of said endoporus is provided with at least 2 location convex tendons, forms cavity, this cavity and the iron core interference fit that supplies the iron core location and installation between the said end face of respectively locating convex tendon.
2. the bobbin of electromagnetic relay according to claim 1 is characterized in that: the inwall of described endoporus is provided with 3 location convex tendons, and respectively locatees between convex tendon and be equally spaced.
