Title: Proximity switch
Inventor: KASAI MASAKI
IPC: H01H36/00
Filed: 1998-12-07
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of any detection error, eliminate any failure caused by a crack, and endure a long time usage, by providing a plurality of ventilation holes that axially penetrating through an annular clearance in a pot core. SOLUTION: A plurality of ventilation holes 36 are provided in a pot core 31, these ventilation holes 36 are provided through a clearance 34 in the pot core 31, are penetrated axially through it and are formed. In assembling this switch, when a detection coil is adequately shaken up to drive air out of the coil wound clearance 34 through the ventilation holes 36, the driven air is released to the atmosphere through inside of a head cap. Thus, even when the pot core 31 is formed in a pot shape, air close to the clearance 34 where the coil is arranged can be perfectly removed. Therefore, swelling or shrinking action following variation of ambient temperature caused by the air accumulating near the coil is eliminated, the detection coil is prevented from causing malfunction, and therefore, quality of products can be improved.

Filed: 1998-12-09
Abstract: PROBLEM TO BE SOLVED: To reduce the number of parts and to enhance a productivity by omitting a batch of a lower bracket fixing structure. SOLUTION: A tightening seat bore portion 17, i.e., a portion of a tightening means M for fixing a lower bracket 14 to a floor bracket 16 is constituted by a bore periphery edge 20; a bore outer periphery wall 21; a supporting wall 22; a bore inner wall 23; and a tightening bore portion 25 formed by bending a plate-like lower bracket 14.
