Structure or technologic problem, traditional inductor have the disadvantage that moisture and dust in external environment are easy in work
As when enter coil inside and the insulation performance of the coil of inductor caused to reduce；Line in coil is in loosening state and in work
It will form noise in work；When inductor is placed in the wiring board of fixed function, need with special glue vacuum encapsulation, this
Technique not only can generate bubble because of meeting air pocket among the line and line of inductance coil, and usually require additional Roaster
Sequence comes curable insulating paint or glue, and energy consumption is big, environmentally friendly poor controllability, high production cost, poor sealing effect, working efficiency
It is low, it cannot achieve automation.In addition, the magnetic core placement in inductance framework is also more not flexible, this gives the detection to inductor to debug
It makes troubles.
Utility model content
The purpose of the utility model is to provide a kind of inductors of high leakproofness, effectively to overcome the above-mentioned prior art not
Foot.
To achieve the goals above, the technical solution adopted in the utility model is: a kind of inductor of high leakproofness, including
Inductance framework, inductance coil, connecting terminal and magnetic core, the inductance framework is equipped with winding slot, in the central axes of inductance framework
It is equipped with tapped through-hole, connecting terminal is fixedly installed in the end of inductance framework, pacifies in the through-hole of inductance framework
Equipped with magnetic core；The inductance coil is made of the copper wires that appearance is equipped with insulating layer, winds on the winding slot of inductance framework
There are several layers copper wires, BOPP rough film is equipped between each layer copper wires, is equipped with to draw at the both ends of inductance coil and lead
Line is wrapped with pressure sensitive adhesive tape in inductance coil；The axial line of the connecting terminal and the axis parallel of inductance framework, connect
Line terminals and extraction wire are welded, and weld is close to the junction of inductance framework and connecting terminal；The magnetic core is integrally in cylinder
Shape is equipped with external screw thread on the outer wall of magnetic core, and the internal screw thread of through-hole matches on the external screw thread and inductance framework of magnetic core.
Preferably, BOPP rough film is equipped between the inductance framework and copper wires.
Further, the connecting terminal is located on the same end of inductance framework, and connecting terminal passes through anti-oxidation processing.
Further, the material of the extraction wire and the material of inductance coil are identical, and the appearance of extraction wire is equipped with absolutely
Edge casing.
Further, the end of the magnetic core is additionally provided with short slot.
Compared with prior art, the utility model has the beneficial effects that the inductor of the utility model, due in each layer copper
BOPP rough film is set between matter conducting wire, BOPP rough film is set between inductance framework and copper wires, and in inductor wire
Circle is wrapped with pressure sensitive adhesive tape, therefore reduces the gap between line layer and line layer, improves the sealing effect of product, also makes to produce
The structure of product is more firm, realizes sealing and coiling synchronised automatic, improves the service life of product；Due to being set on through-hole
The external screw thread being arranged on the internal screw thread and magnetic core set, therefore the magnetic core placement in inductance framework is also very flexible.The utility model
Inductor structure is simple, production is quick, leakproofness is high, long service life.
