Description

Technical Field

[0001] The utility model relates to the technical field of proximity switches, in particular to a proximity switch with a copper needle coil skeleton. Background Art

[0002] A proximity switch, also known as a contactless proximity switch, is a non-contact monitoring device that requires no mechanical contact or pressure to activate. When a metal detector approaches the proximity switch's sensing area, the switch quickly issues an electrical command without contact, pressure, or sparks, accurately reflecting the position and travel of the moving mechanism. Current proximity switches generate a magnetic field through an internal magnetic core and coil. The number of coil turns is a key factor affecting sensitivity. If the current coil has a large number of turns, the outermost coil can easily fall off if the proximity switch is subjected to bumps or vibrations, thereby affecting the proximity switch's operating sensitivity. Therefore, a proximity switch with a copper pin coil bobbin has been designed to address this issue. Utility Model Content

[0003] Aiming at the shortcomings of the existing proximity switches, the purpose of the utility model is to provide a proximity switch with a copper pin coil skeleton, which has the advantages of preventing the outer coil from falling off.

[0005] Preferably, the diameter of the annular outer baffle is d1, the diameter of the annular inner baffle is d2, and the diameter of the winding drum is d3, wherein d3<d1=d2;

[0006] Preferably, the annular inner baffle further has a reinforcement covering ring corresponding to the copper needle extension position;

[0007] Preferably, the number of the copper needles is n, where n≥3;

[0008] The beneficial effect of the utility model is that by arranging an annular inner baffle and an annular outer baffle at both ends of the winding drum, when the coil is bumped and vibrated near the switch, the outermost coil can be blocked by the annular inner baffle and the annular outer baffle, thereby achieving the effect of preventing the outer coil from falling off.
