Description
Technical field
The present invention relates to magnetic switch technical fields, and in particular to a kind of security protection magnetic switch and packaging technology.
Background technique
Magnetic switch is the switching device incuded by magnet, and common magnet has sintered NdFeB, rubber magnet and forever
Magnetic ferrites.It is dry type tongue tongue tube that it, which is switched, and abbreviation tongue tube, the shell of tongue tube is the glass tube of a sealing, in glass
The elastic spring battery plate there are two irony is filled in glass pipe, is also inoculated with a kind of inert gas for being metal rhodium in glass tube.Usually
Two reeds in glass tube are separated, as long as two nodes of tongue tube will be pulled together, and make electricity with magnet close to it
Road conducting.After outer magnetic force disappears, two reeds due to itself elasticity and separate, route also just disconnection.And magnetic switch is usually
It is put into shell by tongue tube and lead, sealant pouring and sealing is then carried out to it, waited after the glue solidifies and finished product is made.
Nowadays the encapsulation of magnetic switch is usually to use epoxy resin encapsulated, and epoxy resin encapsulated time-consuming is longer, be by
A, two kinds of glue of B glue are deployed into required glue than column by 4:1, need to solidify greater than 8 hours at normal temperature, and all
It is that manual operations is difficult control rubber quality, is easy spilling case surface and causes bad order phenomenon；And glue flowing is easy to greatly
It is flowed out from shell aperture, needs to be stamped at outlet hole with thermal capacitance glue, it then again could be by outlet to pressing by thermal capacitance glue with soldering iron
Hole is sealed, and finally the shell processed is placed in one by one on desktop and waits filling epoxy glue, thus in process of manufacture
It is complex, it is inconvenient, to solve the above-mentioned problems, just propose design of the invention.
