Description
Technical field
The utility model relates to a kind of mutual inductors that the enameled wire for being cased with glass bushing is made to input, and belong to mutual inductor technology neck
Domain.
Background technique
Mutual inductor is also known as instrument transformer, and there are two types of mutual inductor types, and wherein current transformer is one such.Electricity
High current can be become low current by current transformer, for measuring or protecting system.Its major function is to become high current in proportion
Standard small electric current (5A or 1A) is changed into, to realize that the automatic control of measuring instrumentss, protection equipment and standardization, miniaturization is set
It is standby, and the type of current transformer is segmented into many kinds according to specification, wherein micro-transformer of current is exactly one such.
In the prior art, micro-transformer of current mainly uses Teflon lead as input current line, and Teflon is led
Line once encounters that winding space is small, and the situation more than number of turns is difficult to realize that high current is become the small electricity of standard by current transformer
The function of stream, if reducing conductor size, there may be overcurrents to burn phenomenon.
Utility model content
It is inputted technical problem to be solved by the utility model is to provide a kind of enameled wire work for being cased with glass bushing
Mutual inductor, it solves Teflon because winding space is small, and number of turns is more and being difficult to realize current transformer becomes high current
The problem of standard small electric current function.
Technical problem to be solved in the utility model takes following technical scheme to realize:
A kind of mutual inductor that the enameled wire work being cased with glass bushing inputs, including iron core, the first insulating layer and primary enamel-cover
Line is wrapped with secondary enameled wire on the iron core, and the iron core and secondary enameled wire are fixedly attached in the first insulating layer, institute
It states fixing sleeve on the outer wall of the first insulating layer and is connected to shielded layer, the external fixing sleeve of the shielded layer is connected to second insulating layer, institute
The bottom for stating iron core is equipped with fixing seat, and the diameter of the fixing seat is greater than the diameter of mandrel bottom, equidistant in the fixing seat
Offer multiple crossed beam trunkings, the external fixing sleeve of the primary enameled wire is connected to glass bushing, one end of the glass bushing according to
Secondary second by the top of iron core, first cable-through hole of the fixing seat side, the top of iron core, the fixing seat
Cable-through hole ..., the top of iron core, n-th cable-through hole in the fixing seat sequence solderless wrapped connection on iron core.
As preferred embodiment, first insulating layer and second insulating layer are one to insulate in external member or mylar
Kind.
As preferred embodiment, the material of the shielded layer is copper foil.
The beneficial effects of the utility model are: the utility model structure is simple, coiling secondary enameled wire, coiling outside iron core
Add the first insulating layer in the outside of secondary enameled wire after the completion, then is used as shielding with a circle copper foil is fixed outside the first insulating layer, and
Second insulating layer is set in the outside of shielded layer, the primary enameled wire of appropriate size is then selected, first puts on the glass of suitable length
Casing, one circle of secondary enameled wire winding on iron core, then the corresponding the number of turns of coiling (the number of turns is greater than 1), winding process to the greatest extent may be used
The case where lap wound can not occur, Teflon is replaced by primary enameled wire and secondary enameled wire, it is small to solve Teflon space, around
Number of wire turns is more and is difficult to realize the problem of high current is become standard small electric current function by current transformer.
Detailed description of the invention

Fig. 2 is the structural schematic diagram of the utility model.
In figure: secondary enameled wire 1, the first insulating layer 2, shielded layer 3, primary enameled wire 4, glass bushing 5, fixing seat 6.
Specific embodiment
In order to which the technical means, creative features, achievable purpose and effectiveness to the utility model are easy to understand, tie below
Conjunction is specifically illustrating, and the utility model is further described.
As shown in Figs. 1-2, a kind of enameled wire being cased with glass bushing makees the mutual inductor inputted, including iron core, the first insulation
Layer 2 and primary enameled wire 4, it is characterised in that: secondary enameled wire 1, iron core and the equal fixing sleeve of secondary enameled wire 1 are wrapped on iron core
It connects in the first insulating layer 2, fixing sleeve is connected to shielded layer 3 on the outer wall of the first insulating layer 2, and the outside of shielded layer 3 is fixedly attached
There is a second insulating layer, the bottom of iron core is equipped with fixing seat 6, and the diameter of fixing seat 6 is greater than the diameter of mandrel bottom, in fixing seat 6
Multiple crossed beam trunkings are equidistantly offered, the external fixing sleeve of primary enameled wire 4 is connected to glass bushing 5, one end of glass bushing 5
Successively line is crossed by second in the top of iron core, first cable-through hole of 6 side of fixing seat, the top of iron core, fixing seat 6
