Detailed Description
Example 1
As shown in fig. 1 to 2, the electromagnet release coil of the present utility model comprises a coil former 1 and an enameled wire 2 wound on the coil former 1, wherein the head end 3 and the tail end 4 of the enameled wire 2 are respectively connected with an outgoing line 5, and the two outgoing lines 5 are respectively used as an input outgoing line and an output outgoing line of a power supply. The two outgoing lines 5 are respectively composed of a twist wire core 10 formed by winding the head end 3 and the tail end 4 of the enameled wire 2 after being folded for many times, and an insulating sleeve 6 sleeved outside the twist wire core 10. The insulating sleeve 6 is desirably a heat shrink tube or a teflon tube or a plastic sleeve, so as to perform the insulating and protecting functions on the twist-shaped wire core 10. When the insulating sleeve 6 is a heat shrinkage tube, the heat shrinkage tube needs to be heated, so that the heat shrinkage tube is tightly wrapped on the outgoing line, and the optimal insulating and protecting effects are achieved. The specific winding method of the twist-shaped wire core 10 is as follows: and fixing two ends of the folded multiple wires, and twisting and winding for multiple times to form a twist-shaped wire core, wherein the wire core winding method is a known technology.
Preferably, a welding part 7 extending out of the insulating sleeve 6 is arranged at the front end of the twist wire core 10, and a soldering tin layer 8 is arranged on the surface of the welding part 7 so as to be convenient for welding with the input end and the input end of a power supply.
Preferably, the head end 3 and the tail end 4 of the enameled wire 2 are ideally folded in half for 3-6 times to meet the requirements of wiring, strength and conductivity, and the requirements of users on the outgoing line are specifically determined. The number of times of twisting is also dependent on the actual requirements, and is usually 5-15 times.
Preferably, two outgoing lines 5 are led out from the same side of the coil bobbin 1, so as to facilitate wiring. And an insulating tape 9 for fixing the lead wire 5 is wound around the bobbin 1. The outgoing line 5 is wound and fixed through the insulating adhesive tape 9, so that the pulling resistance of the outgoing line 5 is improved.
