Abstract
The utility model discloses a transformer light source, the technical key points are that the transformer light source comprises an iron core, a coil wound on the iron core and a shell connected with the iron core; a plurality of mounting slots are arranged on the shell and are internally provided with connecting terminals; the connecting terminals are electrically connected with the coil; a transparent protective shield is arranged on the mounting slots and is detachably connected with the mounting slots. The transformer light source can effectively prevent dust and liquid from entering into the terminals, so the safety of a transformer is improved.
Description
Technical field
The utility model relates to a kind of transformer accessory, and more particularly, it relates to a kind of transformer frequency response.
Background technology
In prior art, transformer frequency response comprises iron core and is wrapped in the coil on iron core, and the housing being connected with iron core, housing is provided with some mounting grooves, in described mounting groove, be provided with splicing ear, power connector end of this transformer does not arrange in the direct exposed outside air of protector splicing ear dust and liquid outward and enters in splicing ear and can cause electric shock accidents.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of transformer frequency response, and this transformer frequency response can effectively avoid dust, liquid to enter splicing ear inside, improves the fail safe of transformer frequency response.
For achieving the above object, the utility model provides following technical scheme: a kind of transformer frequency response comprises iron core and is wrapped in the coil on iron core, and the housing being connected with iron core, housing is provided with some mounting grooves, in described mounting groove, be provided with splicing ear, described splicing ear is electrically connected to coil, and described mounting groove arranges transparent shield, and described transparent shield and mounting groove removably connect.
By adopting technique scheme, transparent shield is set on mounting groove, splicing ear is covered itself and outside air are kept apart, can effectively prevent that dust and liquid from entering in splicing ear, avoid causing electric shock accidents, improve the fail safe of transformer frequency response.
The utility model is further set to: described splicing ear comprises base, line ball securing member and pressing plate, and described pressing plate is set to arc-shaped concave, and described arc-shaped concave is towards base one side depression.
The utility model is further set to: described line ball securing member is bolt.
By adopting technique scheme, splicing ear comprises base, bolt and pressing plate, pressing plate is set to arc-shaped concave, arc-shaped concave is towards base one side depression, pressing plate and base are bolted, while tighting a bolt, bolt extruding arc-shaped concave compresses the electric wire between base and pressing plate, improves the stability of transformer frequency response wiring.
