Description
Technical field
What the utility model waterproof low-frequency antenna related to is a kind of waterproof low-frequency antennas such as keyless access system, storage, logistics system, tire pressure detection, the authentication of animal husbandry animal pets that are applicable to.
Background technology
The encapsulation of present low-frequency antenna, solidifying needs the time long, and it is many to take the place, and production technology is more loaded down with trivial details, and the production cycle is long, and the cost height is unfavorable for producing in batches.And the difficult control of injection moulding production process for encapsulating, the unit for electrical property parameters instability after injection moulding is finished.Present low-frequency antenna adopts structure need use skeleton, the structure more complicated, and volume ratio is bigger.
Summary of the invention
The utility model purpose is at above-mentioned weak point, a kind of waterproof low-frequency antenna is provided, adopts chassis less construction, directly be wound on enamelled wire on the magnetic core, connect electric capacity and draw lead, electric capacity, magnetic core set that coiling is good are lumped together and put into the shell embedding preserve.
The waterproof low-frequency antenna takes following technical scheme to realize:
The waterproof low-frequency antenna comprises magnetic core, insulating tape, electric capacity, enamelled wire coil, lead and shell.At magnetic core coated outside insulating tape, outside magnetic core and insulating tape, be wound with the enamelled wire coil.The shell two ends are provided with installing hole.In shell one side lead-out wire line hole is arranged.Electric capacity one end is connected with an end of enamelled wire coil, and the other end of electric capacity and lead one join, and the other end of enamelled wire coil and lead two join.Described magnetic core, enamelled wire coil and electric capacity are installed in the enclosure, and lead one is drawn by the lead-out wire line hole of shell one side with lead two, are packaged with epoxy sealing glue between shell and magnetic core, enamelled wire coil, electric capacity.
Splicing ear one is equipped with in described lead one end, and splicing ear two is equipped with in lead two ends.
The utility model waterproof low-frequency antenna is reasonable in design, owing to adopt chassis less construction, and simple in structure, easy to use.Magnetic core, enamelled wire coil and electric capacity are installed in the enclosure, adopt the epoxy sealing glue encapsulation, and effectively exclusion of water, dust, organic solvent are to the erosion of antenna.Magnetic core is encapsulated in the epoxy sealing glue, can effectively prevent the influence to antenna electrical performance of cold and hot variation, vibration and pressure, has improved the stability of waterproof low-frequency antenna.

With reference to accompanying drawing 1,2, the waterproof low-frequency antenna comprises magnetic core 5, insulating tape 6, electric capacity 9, enamelled wire coil 7, lead, splicing ear and shell 1.At magnetic core 5 coated outside insulating tapes 6, outside magnetic core 5 and insulating tape 6, be wound with enamelled wire coil 7.Shell 1 two ends are provided with installing hole 2.In shell 1 one sides lead-out wire line hole 4 is arranged.Electric capacity 9 one ends are connected with an end of enamelled wire coil 7, and the other end of electric capacity 9 and lead 1 join, and the other end of enamelled wire coil 7 and lead 29 join.Described magnetic core 5, enamelled wire coil 7 and electric capacity 9 are installed in the shell 1, and lead 1 is drawn by the lead-out wire line hole 4 of shell 1 one sides with lead 29, are packaged with epoxy sealing glue between shell 1 and magnetic core 5, enamelled wire coil 7, electric capacity 9.
Splicing ear 1 is equipped with in described lead one 8 ends, and splicing ear 2 11 is equipped with in lead 29 ends.
Waterproof low-frequency antenna winding method:
With magnetic core 5 wrap insulate adhesive tapes 6, enamelled wire is wound on the magnetic core 8 that has wrapped up adhesive tape.Pin of electric capacity 9 and of enamelled wire coil 7 are welded together.The other end and the lead 1 of electric capacity 9 are welded together, the other end of enameled wire loop 7 and another root lead 29 are welded together.Lead 1 and lead 29 are by the wire guide on the shell 14 or to be connected with the outside.After connection was finished, magnetic core 5, enamelled wire coil 7, electric capacity 9 were all put into shell 1, with an amount of epoxy sealing glue their embeddings are integral.
Two projections lock traces 3 are arranged in the described shell 1, be used for confirming that the epoxy sealing glue that injects is whether an amount of and play the better fixedly effect of epoxy glue.
