Abstract
The utility model discloses an epoxy potting inductance coil, and particularly discloses an epoxy potting inductance coil. The epoxy potting inductance coil comprises a shell and a coil arranged in the shell. The epoxy potting inductance coil is characterized in that the coil comprises a framework that is internally provided with a hollow cavity; the framework at the external side of the hollow cavity is enwound by an enameled wire; the hollow cavity is internally provided with a plurality of directly-superposed E-shaped silicon steel sheets and I-shaped silicon steel sheets; the connecting parts of the E-shaped silicon steel sheets and the I-shaped silicon steel sheets are welded by argon arc welding; and two sides of the framework are provided with a plurality of pinholes. The epoxy potting inductance coil has the advantages that the size of the provided inductance can be controlled according to the size of the air gap needing to be designed; furthermore, the used material is environment-friendly and flame-retardant and is high in safety; and by epoxy potting seal, the epoxy potting inductance coil is dustproof and moistureproof, is long in service life, is safe and reliable for use, and is applicable to large-scope generalization and application.
Description
(1) technical field
The utility model relates to a kind of inductance coil, particularly a kind of epoxy sealing inductance coil.
(2) background technology
Inductance coil is the electric elements that often use in the circuit, can provide suitable inductance to circuit, the method of the inductance coil control inductance that provides is varied, and people are also more and more higher to the requirement of sealing, anti-flammability and the fail safe of inductance coil, and more existing inductance coils can not satisfy people's demand.
(3) summary of the invention
The utility model provides a kind of safe and reliable epoxy sealing inductance coil in order to remedy the defective of prior art.
The utility model is achieved by the following technical solution:
A kind of epoxy sealing inductance coil, comprise housing and be installed in its inner coil, it is characterized in that: coil comprises skeleton, be provided with cavity in the middle of the skeleton, be wound with enamelled wire on the skeleton in the cavity outside, be provided with " E " shape silicon steel sheet and " I " shape silicon steel sheet of the direct closed assembly of multi-disc in the cavity, weld by argon arc welding the junction of " E " shape silicon steel sheet and " I " shape silicon steel sheet, and the skeleton both sides are provided with a plurality of pin holes.
This epoxy sealing inductance coil, tongue in " E " shape silicon steel sheet is provided with air gap between " E " shape silicon steel sheet and " I " shape silicon steel sheet, passes through the size of design air gap during manufacturing, thereby influences the inductance that inductance coil provides.The skeleton both sides respectively are provided with six pin holes, are inserted with 2-12 suture introducing needle on the pin hole, and people can set the quantity of suture introducing needle as required.
The beneficial effects of the utility model are: this epoxy sealing inductance coil, can design the size that size of gaps is provided by the inductance that provides as required, and materials used environmental protection, fire-retardant, safe, by the protection against the tide of epoxy sealing sealing and dustproof, long service life, safe and reliable, be suitable for applying on a large scale.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is the structural representation of the utility model epoxy sealing inductance coil.
Accompanying drawing 2 is the internal structure schematic diagram of the utility model epoxy sealing inductance coil.
Accompanying drawing 3 is the structural representation of silicon steel sheet of the present utility model.
Among the figure, 1 shell, 2 coils, 3 suture introducing needles, 4 pin holes, 5 enamelled wires, 6 skeletons, 7 " E " shape silicon steel sheet, 8 " I " shape silicon steel sheet, 9 argon arc weldings, 10 air gaps.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This epoxy sealing inductance coil, comprise housing 1 and be installed in its inner coil 2, it is characterized in that: coil 2 comprises skeleton 6, be provided with cavity in the middle of the skeleton 6, be wound with enamelled wire 5 on the skeleton 6 in the cavity outside, be provided with " E " shape silicon steel sheet 7 and " I " shape silicon steel sheet 8 of the direct closed assembly of multi-disc in the cavity, the junction of " E " shape silicon steel sheet 7 and " I " shape silicon steel sheet 8 is by argon arc welding 9 welding, and skeleton 4 both sides are provided with a plurality of pin holes 4.Tongue in " E " shape silicon steel sheet 7 is provided with air gap 10 between " E " shape silicon steel sheet 7 and " I " shape silicon steel sheet 8, and skeleton 6 both sides respectively are provided with six pin holes 4, are inserted with 2-12 suture introducing needle 3 on the pin hole 4.
This epoxy sealing inductance coil, after carefully connecting the wire during manufacturing whole Inside coil 2 being put into housing 1 toasts at curing oven then together, baking finishes back with the good epoxy resin embedding of preheating, salable dust and moisture, improve its insulating properties, anti-flammability, make this inductance coil durable, during use, by suture introducing needle 3 it is plugged on the equipment to use and gets final product, because tongue in " E " shape silicon steel sheet 7, leave air gap 10 between " E " shape silicon steel sheet 7 and " I " shape silicon steel sheet 8 welding backs, the size of air gap 10 can influence the size of inductance, therefore the size of air gap 10 during fabrication people can design voluntarily as required, so that suitable inductance to be provided to circuit, very easy to use.
