Abstract
The utility model discloses an electromagnetic switch coil framework. The electromagnetic switch coil framework comprises a core winding body, a first flange portion and a second flange portion, wherein the first flange portion and the second flange portion are arranged in parallel at both ends of the core winding body, a center of the core winding body is provided with a shaft hole, and an inner wall of the shaft hole is provided with multiple parallel convex ribs in an axial direction. According to the electromagnetic switch coil framework, the convex ribs are arranged on the inner wall of the shaft hole in the axial direction, so an axial positioning effect is exerted for axial direction slide of an iron core, and problems of axial direction slide difference or imperfect slide of the iron core caused by processing error can be effectively eliminated, and thereby normal operation of the electromagnetic switch is guaranteed.
Description
Technical field
The utility model relates to a kind of electromagnetic switch, refers to especially a kind of coil rack of electromagnetic switch.
Background technology
Electromagnetic switch is as the term suggests be exactly the switch of using magnet control, the namely combination of electromagnet and switch.Produce electromagnetic attraction behind electromagnet coil power, movable core pushes away or the Drawing switch closing of contact, thereby connects institute's control circuit.Electromagnetic switch is widely used in starting and the control motor.Coil rack is a vitals of electromagnetic switch, its structure include a tubular around core, and be set in parallel in the first flange part and the second flange part around the core two ends, wherein be provided with for iron mandrel the axis hole to activity orientation around the center of core.The inner wall section of the axis hole of existing coil rack is circular, and because there are trueness error in coil rack and iron core in processing and manufacturing, causes iron core to slide in the axial direction smooth not and accurate, has affected the electromagnetic switch normal operation.
Summary of the invention
The purpose of this utility model is the shortcoming and defect that exists in order to overcome prior art, and provides a kind of can endwisely slipping to iron core to carry out guide-localization, thereby ensures the coil rack of the electromagnetic switch of electromagnetic switch normal operation.
For achieving the above object, the technical solution of the utility model is to include around core body, and be set in parallel in the first flange part and the second flange part around the core body two ends, and wherein be provided with axis hole around the center of core body, be provided with many axial convex tendons that are parallel to each other on the inwall of described axis hole.
Further arrange that to be the length of described axial convex tendon equate setting with axial height around core body.
Further arranging is that described axial convex tendon is provided with 8, is on the inwall that circumference uniform distribution is arranged on axis hole.
Further setting is that the outer surface of described axial convex tendon is the arcwall face of indent.This setting, because iron core is generally cylindricly, the outer surface of axial convex tendon is set to the arcwall face of indent, can make iron core and axially the axially directed locating effect of convex tendon is better.
The utility model arranges axial convex tendon by the inwall at axis hole, endwisely slipping of iron core played the effect of axial location, can effectively overcome the reason because of mismachining tolerance, and the iron core slip axial difference that causes or the slack problem of sliding have effectively guaranteed the normal operation of electromagnetic switch.
Below in conjunction with specification drawings and specific embodiments the utility model is done further introduction.

Embodiment
Below by embodiment the utility model is carried out concrete description; only be used for the utility model is further specified; can not be interpreted as the restriction to the utility model protection range, the technician in this field can make some nonessential improvement and adjustment to the utility model according to the content of above-mentioned utility model.
Embodiment of the present utility model shown in Fig. 1-4, include around core body 1, and be set in parallel in the first flange part 11 and the second flange part 12 around the core body two ends, wherein be provided with axis hole 13 around the center of core body 1, be provided with many axial convex tendons 14 that are parallel to each other on the inwall of described axis hole.The length of the described axial convex tendon 14 of the present embodiment equates with the axial height around core body 1 to arrange, in addition, this axial convex tendon 14 is provided with 8, be on the inwall that circumference uniform distribution is arranged on axis hole 13, in addition, the outer surface of this axial convex tendon 14 of the present embodiment is the arcwall face 141 of indent, makes its guide-localization effect better.
