Description
Technical field
The utility model relates to a kind of rectangular configuration filter inductor, belongs to inductors technique field.
Background technology
The coil of the filter inductor of existing rectangular configuration and the connected mode of metal terminal are to adopt terminal to be close to coil to form bonding by melting welding, the structure that this single employing welding manner connects, when by the metal terminal of inductor and relevant device welding, metal terminal will generate heat, the bonding position of coil and metal terminal will reappear molten condition, under coil and the impact of shell self gravitation, just there will be terminal and coil segregation phenomenon simultaneously, cause product because of open failure.
The inductor of existing surface-mount type is when welding with PCB substrate, if the metal terminal of Surface Mount face does not expose, owing to being difficult to after product ontology hide, by external inspection, it covers tin situation to metal terminal, and the dry joint phenomenon existing like this can not detect the very first time, easily makes product failure.
Summary of the invention
The technical problems to be solved in the utility model be to provide a kind of can guarantee metal terminal and coil annexation reliable, simultaneously easily convenient welding checks the rectangular configuration filter inductor of welding quality, can overcome the deficiencies in the prior art.
The technical solution of the utility model is: rectangular configuration filter inductor, it comprises enameled wire loop and the bar magnet being arranged in magnetic core outer shell, bar magnet is plugged in enameled wire loop, the termination, two ends of enameled wire loop is connected with metal terminal, one end of metal terminal is positioned at outside magnetic core outer shell, termination is the termination of paint removal, zinc-plated rear formation, bending 90 degree in termination are vertical with enameled wire loop end face, on metal terminal, be provided with U-shaped bayonet socket, U-shaped bayonet socket is crimped on the termination that is provided with tin coating, in the junction of U-shaped bayonet socket and termination, is provided with Surface Mount Welding Structure.
Above-mentioned rectangular configuration filter inductor is that described enamelled wire is enamel-cover circle line or enamel-cover flat wire.
Aforesaid rectangular configuration filter inductor is that the end that is positioned at the metal terminal outside magnetic core outer shell is provided with 90 degree flangings.
Aforesaid rectangular configuration filter inductor is that described metal terminal be take brass as bottom, at brass, is provided with electrotinning layer outward.
Aforesaid rectangular configuration filter inductor is that the magnetic core outer shell of described rectangle, bar magnet are iron powder system or ferrite system.
Compared with the prior art, the utility model is vertical with enameled wire loop end face by enameled wire loop termination bending 90 degree, and on metal terminal, be provided with U-shaped bayonet socket, U-shaped like this bayonet socket just can be crimped on the termination that is provided with tin coating, the structure that makes script only adopt welding manner to connect has increased mechanical type and has fixed, can guarantee also to there will not be contact to depart under thermofusion device, promote quality and the useful life of inductor.The end that is positioned at the metal terminal outside magnetic core outer shell is provided with 90 degree flangings, and it is visual that 90 degree flanging designs can make the inconvenient macroscopic metal terminal tin coating of script facilitate, and so just can pinpoint the problems in advance, avoids rosin joint, dry joint, further improves equipment quality.
