Description

【考案の詳細な説明】 本考案は継電器用電磁石の改良構造に関するものである
[Detailed Description of the Invention] The present invention relates to an improved structure of an electromagnet for a relay.

This type of electromagnet generally includes a coil bobbin made of insulating resin with a coil wound around its outer periphery, a T-shaped iron core whose head protrudes laterally, and an L-shaped yoke, with the iron core head touching the outside of the coil bobbin. It consists of a structure in which an iron core is inserted into a coil bobbin so that they are in contact with each other, and the ends of the iron core are caulked and fixed to a yoke.

ことがある。
In such electromagnets, the coil bobbin is fixed by clamping the coil bobbin between the iron core head and the yoke, but if the caulking between the iron core end and the yoke is weak, the coil bobbin will rotate and the coil output wire will be damaged. If wire breakage occurs or the caulking is too strong, the iron core may be deformed and the contact state between the iron core head and the armature magnetically attracted to it may change, resulting in contact malfunction.

The present invention solves this problem and provides a means for stably fixing the coil bobbin at all times with a simple structure.One embodiment of the present invention will be described below with reference to the accompanying drawings.

The main iron core 1 is integrally equipped with a protrusion 3 on the back side of the iron core head 2, but this protrusion 3 is processed into a header of the iron core, that is, the iron core material is fixed in a fixed mold so that its end is exposed. It is formed by providing a concave portion in advance on the surface of the fixed mold when crushing it in a flat state and making the exposed end protrude laterally to obtain the iron core head 2. .

Then, the iron core 1 is inserted into the through hole of the coil bobbin 4 as shown in FIG. 2, and the iron core end 7 is caulked with the iron core end 7 inserted into the hole of the L-shaped yoke 6. The projection 3 bites into the outer edge of the coil bobbin 4 and is fixed to the coil bobbin.

As described above, according to the present invention, by setting the iron core to the yoke somewhat weakly, the rotation of the coil bobbin can be reliably stopped without causing deformation of the iron core, resulting in high reliability. The practical effects of this method are remarkable, such as the ability to obtain a relay.

It consists of a cylindrical coil bobbin made of insulating resin with a coil wound around its outer circumference, a T-shaped iron core with a head protruding to the side, and a yoke. In an electromagnet formed by inserting the iron core into the yoke and fixing the end of the iron core to the yoke, a protrusion for preventing the coil bobbin from rotating is integrally formed on the inner surface of the iron core head, and the protrusion prevents the coil bobbin from rotating when the coil bobbin is fixed. An electromagnet characterized in that it bites into the outside of the coil bobbin.
