Detailed Description

The embodiments of the present invention will be further explained with reference to the accompanying drawings:

as shown in the figure, the high-voltage-resistant proximity switch comprises a shell, wherein the shell comprises a head end 1 and a tail end 2, the head end 1 comprises a placing section 11 and a connecting section 12, the head end 1 and the tail end 2 are detachably connected, a magnetic core protection cover and a backstop ring 3 are arranged in the head end 1, the magnetic core protection cover is arranged at the placing section 11, the placing section 11 is provided with an opening 13 which is folded inwards, the inner wall of the placing section forms an annular step, the magnetic core protective cover is provided with a positioning part 14 which is arranged in the opening 13 in a penetrating way, the bottom of the positioning part 14 is provided with a rounding 15 which is in sealing fit with the annular step, the technical proposal ensures that the rounding is in sealing fit with the annular step by arranging the rounding which is in interference fit with the opening of the placing section on the magnetic core protective cover and the check ring at the rear end provides pre-tightening pressure of the rounding and the annular step, and has the advantages of cost saving, convenient installation, good sealing effect and better prevention of oil from permeating into the switch.

The magnetic core safety cover includes first safety cover 4 and second safety cover 5, first safety cover 4 and second safety cover 5 form inside confined cavity 6, cavity 6 is used for placing the magnetic core, 5 bottoms of second safety cover are equipped with wiring hole 7, and location portion setting in this embodiment is in first safety cover, first safety cover 4 makes the magnetic core be in under the suitable environment, second safety cover 5 sets up between first safety cover 4 and backstop ring 3 to compress tightly by backstop ring 3, make first safety cover and head end 1 entry zero clearance, first safety cover 4 and 5 junctions zero clearance of second safety cover, place the magnetic core in the cavity 6, place the circuit board in the linkage segment 12, the connecting wire passes wiring hole 7 intercommunication magnetic core and circuit board.

First protection cover 4 with place and be equipped with O type sealing washer 16 between the section 11 to with magnetic core safety cover fixed connection, seted up the ring channel on the circumferential surface of first protection cover and supply the installation of O type sealing washer.

The linkage segment 12 of head end 1 is equipped with the internal thread, the stopping ring 3 is equipped with the external screw thread, the internal thread of linkage segment 12 and the 3 external screw thread threaded connection of stopping ring make things convenient for stopping ring 3 in the dismantlement and the installation of linkage segment 12, and threaded connection is firm reliable, when using, will stop ring 3 along linkage segment 12 screw to with the contact of second safety cover 5, realize preventing that the magnetic core safety cover from receiving impact displacement's function, stopping ring 3 contacts with second safety cover 5 each other to provide the packing force that compresses tightly second safety cover 5 and first safety cover 4 each other, still provide the packing force that compresses tightly of each other of radius and annular step face.
