Electromagnetic valve coil framework structure

Abstract

The invention discloses an electromagnetic valve coil framework structure which is a cylindrical structure. Two ends of a coil framework are provided with bosses, the coil framework is provided with wire grooves B in one sides of the bosses and further provided with a plurality of wire grooves A, and the wire grooves A are uniformly and axially distributed along the coil framework and positioned between the wire grooves and the bosses. A cross section curve of each wire groove A is a 1 / 2 arc, a cross section curve of each wire groove B is a 1 / 4 arc, the diameter of the cross section curve of each wire groove A is equal to that of a wound enameled wire, and the diameter of the cross section curve of each wire groove B is equal to that of the wound enameled wire. By the wire grooves A and the wire grooves B of the coil framework, defects of low flatness and compactness in winding array of coils at present can be improved, manufacturability in coil winding array on the electromagnetic valve coil framework is improved, and accordingly performance stability of products is improved.

Description

technical field [0001] The invention relates to the technical field of solenoid valve manufacturing, in particular to a solenoid valve coil skeleton structure. Background technique [0002] Solenoid valves have been widely used in various electrical appliances, medical, transportation and other daily equipment and instruments, and have become an indispensable part of our daily life; however, as a coil processing enterprise that is an important part of solenoid valve production, how to make the winding machine It has always been a problem for them to be able to wind a flat, beautiful, solid and beautiful coil on the bobbin. This is mainly because the winding surface shape of the current bobbin frame structure is the side of the cylinder. Due to the high smoothness of the side of the cylinder, it is easy to cause the winding to slip and not be compact when the first layer of the bobbin is wound. , there are gaps and other phenomena, but the winding arrangement of the first la...

Problems solved by technology

This is mainly because the winding surface shape of the current bobbin frame structure is the side of the cylinder. Due to the high smoothness of the side of the cylinder, it is easy to cause the winding to slip and not be compact when the first layer of the bobbin is wound. , there are gaps and other phenomena, but the winding arrangement of the first layer is not compact, and the appearance of gaps will directly affect the winding arrangement of the subsequent layers. As the number of winding layers continues to increase, this phenomenon of uneven coil arrangement It will be more and more obvious that the performance will be superimposed layer by layer

The wiring is uneven and not beautiful; the work efficiency of workers is low, which greatly reduces the performance of the coil and increases the loss of the coil, thus affecting the working performance of the product
