Description
Technical field
The utility model relates to inductance technical field, refers in particular to a kind of inductor.
Background technology
Inductor is to be the element that magnetic energy stores electric energy conversion.The structure of inductor is similar to transformer, but only has a winding.Inductor has certain inductance, and it only hinders the variation of electric current.If inductor is under the state that does not have electric current to pass through, when circuit is connected, it will be attempted to hinder electric current and flow through it; If inductor under the state that has electric current to pass through, when circuit disconnects it will to attempt to maintain electric current constant.Inductor claims again choke, reactor, dynamic reactor.Inductor mainly plays the effects such as filtering, vibration, delay, trap in circuit, screens in addition signal, filtered noise, stabling current and suppresses the effects such as Electromagnetic Interference.Inductance is exactly together with electric capacity in the modal effect of circuit, forms LC filter circuit.Electric capacity has the characteristic of " resistance direct current, logical interchange ", and inductance has the function of " perfectly straight stream, resistance exchanges ".If by LC filter circuit, so, interchange interference signal will be become thermal energy consumption by inductance and fall the direct current with many interference signals; The direct current that becomes purer is when the inductance, and interchange interference signal wherein is also become magnetic strength and heat energy, frequency higher the most easily by inductive impedance, this just can suppress the interference signal of upper frequency.The skeleton of existing inductor and connecting pin are embedded mostly, and its connecting pin is easily loosening, and mostly on inductance framework, only open two fairleads for connecing lead-in wire circle, and this structure wiring is inconvenient.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, easy for installation, inductor that pin is connected firmly is provided.
For achieving the above object, technical scheme provided by the utility model is: a kind of inductor, the main body framework of described inductor is integrated injection mo(u)lding, main body middle part is the square tube type wrapping post of hollow, wrapping post one end is pedestal, the other end is cover plate, is equipped with the ventilative heat dissipation channel being communicated with wrapping post centre bore on base and cover plate; Outside cover plate, broad ways is provided with the horizontal holddown groove of indent, and pedestal is provided with the pedestal holddown groove matching with horizontal holddown groove, and pedestal two ends are equipped with the wire casing of n indent, 2≤n≤7; Base bottom is provided with connecting pin, described connecting pin is two, lays respectively at the diagonal position of base bottom, and connecting pin and main body integrated injection molding are fastening, on wrapping post, around volume, have coil, the coil pin after volume respectively from the wire casing at pedestal two ends through being fixed on corresponding connecting pin around volume again; Coil outside is coated with insulating paper shell; Fixed cover top card is contained in horizontal holddown groove, and fixed cover bottom is installed in pedestal holddown groove, and fixed cover outside seals by carcass.
The utility model has the advantage of: connecting pin is directly just placed in mould when skeleton injection moulding, after inductance assembling is produced, connecting pin is without bonding in addition, and it is firm to connect, not loosening, effectively increases the useful life of inductance; Coil pin after volume is directly on connecting pin, convenient and practical, adopts the holddown groove of indent, and first makes fixed cover fixing more fastening, is difficult for becoming flexible, and second can reduce raw material utilization rate, and then effectively reduces production costs; Adopt the heat dissipation channel of hollow to be conducive to coil heat radiation, the useful life of extension coil.
Accompanying drawing explanation
Fig. 1 is main body framework schematic diagram of the present utility model.
Fig. 2 is overall structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with institute's drawings attached, the utility model is described in further detail, preferred embodiment of the present utility model is: referring to accompanying drawing 1 and accompanying drawing 2, the main body framework of the inductor described in the present embodiment is integrated injection mo(u)lding, main body middle part is the square tube type wrapping post 1 of hollow, wrapping post 1 one end is pedestal 2, the other end is cover plate 3, is equipped with the ventilative heat dissipation channel 4 being communicated with wrapping post 1 centre bore on pedestal 2 and cover plate 3; Cover plate 3 outside broad wayss are provided with the horizontal holddown groove 5 of indent, and pedestal 2 is provided with the pedestal holddown groove 6 matching with horizontal holddown groove 5, and pedestal 2 two ends are equipped with wire casing 7,2≤n≤7 of n indent; Pedestal 2 bottoms are provided with connecting pin 8, described connecting pin 8 is two, lay respectively at the diagonal position of pedestal 2 bottoms, connecting pin 8 is fastening with main body integrated injection molding, on wrapping post 1, around volume, have coil 9, the coil pin after volume respectively from the wire casing 7 at pedestal 2 two ends through being fixed on corresponding connecting pin 8 around volume again; Coil 9 outsides are coated with insulating paper shell 10; Fixed cover 11 top card are contained in horizontal holddown groove 5, and fixed cover 11 bottoms are installed in pedestal holddown groove 6, and fixed cover 11 outsides seal by carcass 12.Connecting pin is directly just placed in mould when skeleton injection moulding, and after inductance assembling is produced, it is firm that connecting pin connects, not loosening, effectively increases the useful life of inductance; Adopt the holddown groove of indent, first makes fixed cover fixing more fastening, it is difficult for loosening, and second can reduce raw material utilization rate, and then effectively reduces production costs.
The embodiment of the above is only the preferred embodiment of the utility model, not with this, limits practical range of the present utility model, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in protection range of the present utility model.
