Description
Technical field
The present invention relates to a kind of magnetic latching relay, particularly relate to a kind of armature part of magnetic latching relay and the syndeton of base.
Background technology
Magnetic latching relay generally includes magnetic circuit system, contact system, pushing portion and base, and wherein, magnetic circuit system is generally made up of magnetic circuit part and armature part, and the two is normally fixed on base or bobbin.For plastics circular shaft formula armature structure, ensure relay reliable fit in course of action, avoid, so the assembling process of armature shaft and base holes is generally interference fit, and the magnitude of interference is larger, and assembly reliability is higher, but the magnitude of interference is larger, the possibility that assembling process produces soft flocks is larger, and therefore, the axis hole over-surplus fit structure of armature part and base designs particularly important.
The armature part of existing magnetic latching relay and the hole axle fit structure of base are generally designed to simple circular shaft and join borehole structure, namely, the armature part of the magnetic latching relay of prior art is provided with circular rotating shaft, base is provided with circular hole, the axis of circular hole is in being horizontally disposed with, peristome is provided with in the side-walls on one side of circular hole, when the rotating shaft of armature part will load the circular hole of base, load from peristome, the circular shaft of existing armature part and base is joined circular hole scheme and is mainly contained two kinds of architectural features, one is interference fit scheme, namely the peristome of the circular hole of base and the circular shaft of armature part are interference fit, like this, the height dimension of peristome is just less than the height dimension between the upper lower wall of circular hole, height dimension between the upper lower wall of circular hole i.e. the diameter dimension of circular hole, and usually need that there is certain magnitude of interference, this structural design, after the circular hole of the circular shaft loading base of armature part, owing to there being the larger magnitude of interference, not easily deviate from, reliability is better, but, load in the process of the circular hole of base at the circular shaft of armature part and easily produce assembling soft flocks, thus affect the stability of relay parameter, another kind is without interference fit scheme, namely the peristome of the circular hole of base and the circular shaft of armature part are without interference fit, like this, the height dimension of peristome will be designed to the height dimension be not less than between the upper lower wall of circular hole, this structural design, load in the process of the circular hole of base can not produce assembling soft flocks at the circular shaft of armature part, but, because the height dimension of peristome is comparatively large, the circular shaft of armature part is easily deviate from from the circular hole of base, thus causes product failure.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art, a kind of armature part of magnetic latching relay and the syndeton of base are provided, can either ensure that the rotating shaft of armature part is not easily deviate from behind the hole loading base, the rotating shaft due to armature part is avoided to deviate from and cause the drawback of product failure to occur, thus improve the reliability of product, the plastics soft flocks making again the rotating shaft of armature part produce in the process in the hole of loading base is little, thus ensure that the stability of relay parameter.
The technical solution adopted for the present invention to solve the technical problems is: a kind of armature part of magnetic latching relay and the syndeton of base, comprise armature part and base; Described armature part is provided with circular rotating shaft, and described base is provided with the axis hole of the rotating shaft for supporting described armature part; Rotate in the axis hole that the rotating shaft of described armature part can be engaged in base, magnetic latching relay reset or set time, described rotating shaft will along positive direction or counter-rotation to reset settling position or set settling position place in axis hole; The axis hole of described base while be provided with the peristome for the rotating shaft of described armature part being loaded axis hole; The height dimension of described peristome is less than the height dimension between the upper roof of the axis hole of base and lower diapire; The rotating shaft of described armature part is when loading the axis hole of base along described peristome, described rotating shaft is provided with in short transverse the portion of stepping down, rotating shaft is made to be only micro-interference fit with described peristome after portion is stepped down in subduction, when rotating shaft goes to reset settling position or set settling position in axis hole, the portion of stepping down of rotating shaft departs from the position of the short transverse of rotating shaft gradually, make the magnitude of interference of rotating shaft between short transverse and peristome increase to maximum gradually, thus prevent rotating shaft from exiting from axis hole.
The portion of stepping down of described rotating shaft is one, is located at top or the bottom of the described short transverse of rotating shaft.
