Abstract
The utility model discloses a static iron core for a magnetic switch. The static iron core comprises a static iron core body which consists of guide post and a positioning plate, and the static iron core body is internally provided with a notch; the notch is a tapered notch whose section is trapezoidal; the static iron core body is integrally formed through extrusion by adoption of a cold heading machine; and the static iron core body is made of metal material. The static iron core for the magnetic switch has the beneficial effects of practicability, reduced production cost, and convenient use and mounting, and the design of the tapered notch enables deformation on the left and right sides when a spring is compressed, but a hole wall is not touched, friction does not occur, resistance does not exist, and thus the performance of the product is improved, and the service life of the magnetic switch is prolonged.
Description
Technical field
The utility model relates to a kind of magnetic switch accessory, particularly a kind of magnetic switch static iron core.
Background technology
Static iron core is the indispensable part of magnetic switch, and its effect is to fit in electromagnet with coil windings, strengthens magnetic field, also plays the size matching effect simultaneously.Notch in the existing static iron core adopts the design of straight shape, and is large with the gap that its inner return spring external diameter cooperates, and spring can be offset on free both sides, produce eccentric, compression is distortion easily, affects the stability of magnetic switch, has shortened the useful life of magnetic switch.
The utility model content
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and a kind of novel magnetic switch static iron core is provided.
To achieve these goals, the utility model institute Adopts measure:
A kind of magnetic switch static iron core comprises the static iron core body that is comprised of lead and positioning disk, has notch in the described static iron core body;
Described notch is that a cross section is trapezoidal conical rebate;
Described static iron core body adopts one-body molded the making of cold headers extruding;
Described static iron core body adopts metal material to make.
The beneficial effects of the utility model: practicality, reduced production cost, production cost is low, use, easy for installation, the design of conical rebate, so that about during spring-compressed distortion is arranged, but can not touch hole wall, not produce friction, non-resistance, thereby improve the performance of product, prolonged the useful life of magnetic switch.
Description of drawings
Fig. 1, planar structure schematic diagram of the present utility model.
Embodiment
A kind of magnetic switch static iron core comprises the static iron core body that is comprised of lead 1 and positioning disk 2, has notch 3 in the described static iron core body; Described notch 3 is that a cross section is trapezoidal conical rebate; Described static iron core body adopts one-body molded the making of cold headers extruding; Described static iron core body adopts metal material to make.
Use the time of the present utility model, the utility model is installed on the magnetic switch, have notch 3 in the described static iron core body, notch 3 is that a cross section is trapezoidal conical rebate, and conical rebate is suitable for reading less, the fixing spring external diameter can not be offset, end opening is larger, distortion is arranged about during spring-compressed, but can not touch hole wall, do not produce friction, non-resistance, thus the performance of product improved, prolonged the useful life of magnetic switch; Described static iron core body adopts one-body molded the making of cold headers extruding; Described static iron core body adopts metal material to make, and production cost is low, and production efficiency is high, thereby has realized the purpose of this utility model.
Those skilled in the art's simple change and replacement in this area all are within the protection range of the present utility model.
