Description
Technical field
The utility model relates to a kind of magnetic switch, particularly relates to a kind of tongue tube magnetic switch.
Background technology
Tongue tube magnetic switch belongs to an annex on magnetic fluid level gauge, ties up outside the main cavity of liquid level, is exclusively used in the signaling switch controlling height of liquid level.The magnet tied up outside tongue tube makes it magnetic switch and has retention performance, the magnetic float of liquid level gauge moves up and down with media fluid, by being magnetically coupled on magnetic switch in float, making the original normally opened contact of switch become closed or original normally-closed contact and becoming unlatching.
Existing magnetic switch holding wire is directly welded on the pin of tongue tube, and the position of tongue tube in Switch main body relies on silica gel to fix.Change because silica gel can produce the position that dilatation makes tongue tube in Switch main body, and the pin of tongue tube deforms magnetic dry-reed tube switch can be caused malfunctioning.
Utility model content
The purpose of this utility model solves the problems of the prior art, provides a kind of tongue tube magnetic switch.
The technical solution of the utility model is: a kind of tongue tube magnetic switch, comprises a Switch main body and is arranged on the outlet nut of this Switch main body one end; Also comprise pcb board, heat-shrink tube and be provided with the tongue tube of magnet; The centre of described pcb board is hollow, and described tongue tube is placed in this hollow position, and the pin of described tongue tube is welded on described pcb board; Offer a bar-shaped trough in one end of described outlet nut, described pcb board inserts in this bar-shaped trough; Described heat-shrink tube is wrapped in the outside of described tongue tube, pcb board.
Preferably, described outlet nut is screwed onto one end of described Switch main body.
Preferably, one end of described outlet nut offers wire hole, is provided with the electric wire connected with the pin of described tongue tube in this wire hole.
Preferably, described magnet is two pieces, is pasted onto the outside of described tongue tube.
Preferably, described magnet is bar shaped.
The utility model have employed the pcb board that centre hollows out, and is placed in one by the tongue tube being stained with magnet, and the pin of tongue tube is welded on pcb board, and the rigidity of such tongue tube improves greatly; Outlet nut end is opened a bar-shaped trough, and inserted in outlet nut groove by the pcb board being welded with tongue tube, such tongue tube just correctly can be located and can not be walked about in Switch main body; At pcb board and tongue tube overcoat heat-shrink tube and pyrocondensation is shaping, the pin of such tongue tube and the dielectric strength of Switch main body increase substantially.
The utility model solves the existing product magnetic switch problem that easily malfunctioning, dielectric strength is low.Improve the quality of existing magnetic switch, there will not be exfactory inspection qualified, use the phenomenon of a period of time malfunctioning switch, thus the reliability of tongue tube magnetic switch and quality are improved greatly, dielectric strength also increases substantially simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the inner side-looking of the utility model;
Fig. 2 is the structural representation of the utility model inside top.
Embodiment
The technological means realized to make the utility model, technical characteristic, utility model object and technique effect are easy to understand, and below in conjunction with concrete diagram, set forth the utility model further.
A kind of tongue tube magnetic switch as shown in Figure 1, 2, comprises a Switch main body 1 and is arranged on the outlet nut 2 of this Switch main body one end; Switch main body 1 in the utility model is the parts of interior hollow one end open, be an airtight accommodating chamber in the middle of it, internal thread is provided with at this end of opening, one end of outlet nut 2 is provided with external screw thread, by above-mentioned internal thread, externally threaded cooperation, outlet nut 2 can be made to be screwed onto on Switch main body 1.
The utility model also comprises pcb board 3, heat-shrink tube 4 and is provided with the tongue tube 6 of magnet 5.Magnet 5 is two pieces, is pasted onto the outside of described tongue tube 6.Magnet 5 of the present utility model is bar shaped.Under the impact of outside magnetic field, the reed of tongue tube 6 can switch and pin this state by two interpolars, forms a bistable switch.
The centre of pcb board 3 of the present utility model is hollow, and described tongue tube 6 is placed in this hollow position, and the pin 61 of tongue tube 6 is welded on pcb board 3; One end of outlet nut 2 offers wire hole, is provided with the electric wire 62 connected with the pin 61 of described tongue tube 6 in this wire hole.
Offer a bar-shaped trough 21 in one end of outlet nut 2, the size of this bar-shaped trough 21 and the form fit of pcb board, above-mentioned pcb board 3 can be made to insert in this bar-shaped trough 21; Heat-shrink tube 4 is wrapped in the outside of tongue tube 6, pcb board 3, and heat shrink is a seal cavity, is then tightened on Switch main body 1 by outlet nut 2.
The utility model have employed the pcb board that centre hollows out, and is placed in one by the tongue tube being stained with magnet, and the pin of tongue tube is welded on pcb board, and the rigidity of such tongue tube improves greatly; Outlet nut end is opened a bar-shaped trough, and inserted in outlet nut groove by the pcb board being welded with tongue tube, such tongue tube just correctly can be located and can not be walked about in Switch main body; At pcb board and tongue tube overcoat heat-shrink tube and pyrocondensation is shaping, the pin of such tongue tube and the dielectric strength of Switch main body increase substantially.
The utility model solves the existing product magnetic switch problem that easily malfunctioning, dielectric strength is low.Improve the quality of existing magnetic switch, there will not be exfactory inspection qualified, use the phenomenon of a period of time malfunctioning switch, thus the reliability of tongue tube magnetic switch and quality are improved greatly, dielectric strength also increases substantially simultaneously.
Be only the utility model preferred embodiment in sum, be not used for limiting practical range of the present utility model.Namely all equivalences done according to the content of the utility model claim change and modify, and all should belong to technology category of the present utility model.
