Description
Technical field
The utility model relates to a kind of inductance coil, relates in particular to the inductance element that a kind of iron core is frame-shaped construction.
Background technology
In prior art, conventional inductance coil mostly adopts annular core, by coil encircling ring-type iron core and the inductance coil of complete; For ring-type iron core, in long-term use, we have found following defect:
The outside of the inductance coil 1, forming via annular core is difficult to reliably be clamped, and is therefore not easy to the processing of automation;
2, the coiling of annular core is difficult to adopt full-automatic machine coiling, causes the coiling time long, and efficiency is low;
3, coil directly contacts the characteristic that iron core affects inductance coil;
4, coil is exposed, easily by external interference, common are the components and parts such as chip inductance coil is formed to electromagnetic interference, is applied to some credit unions of audio field generations and utters long and high-pitched sounds.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned deficiency of the prior art, a kind of inductance coil is provided, and the production and processing of its applicable automatic high-efficiency rate, can be reliably with outside isolated, by external environment, do not affected the working stability of inductance coil own.
The utility model solves the technical scheme that its technical problem adopts: a kind of inductance coil, comprise rectangle iron core, rectangle iron core is formed in one around the iron core of rectangular periphery, it has two iron core column that are parallel to each other, a coil block is set respectively in two iron core column, is specially First Line coil assembly and the second coil block;
Also comprise pedestal, pedestal is installed with described rectangle iron core, and pedestal bottom is provided with a plurality of pins;
Described rectangle iron core adopts casting die one-body molded;
Described coil block comprises the bobbin that is sleeved on iron core column outer surface, bobbin is that two symmetrical semicircle body snappings form, the edge in opposite directions of two semicircle bodys arranges respectively boss and docking groove, and boss is put glue after embedding in docking groove in docking groove;
The outer surface coiling of described bobbin, coil comprises two lead-out wires;
Described coil external card is connected to metal-back, and metal-back is elastic metallic shell, its for cross section be C type, comprise two free ends, between two free ends, form bayonet socket, described lead-out wire is drawn via bayonet socket, between described metal-back and coil, is filled with glue layer; On described bayonet socket, put glue;
Described lead-out wire is connected to the pin on pedestal.
Further: in above-mentioned glue layer, there is Magnaglo; Described metal-back is made by iron nickel material.
Further: above-mentioned core limb is cylindrical structure.
A kind of inductance coil described in the utility model, it has the following advantages:
1, compared to ring-type inductance coil, shaped as frame of the present utility model (rectangle) core structure is convenient to and is clamped, and is that assembling or the full-automatic coiling of automation is all very convenient, and efficiency is high;
2, in coil block, coil winding is in bobbin surface, and bobbin reliably docking is sleeved on core limb, and coil does not directly contact core limb, can not affect inductance coil characteristic;
3, adopt metal-back reliably to shield inductance coil itself, make inductance coil be difficult for being affected by external environment, metal-back is C type buckle structure simultaneously, can be connected to easily coil outside, metal-back and coil are directly also fixed by glue simultaneously, very reliable; The lead-out wire of coil has the bayonet socket of C type metal-back to draw very easily, has guaranteed that lead-out wire is unaffected, and lead-out wire can reliably be connected to easily pin in conductively-closed.
