Description
Technical field
A kind of micro-transformer of current secondary current coil insulation external member is the utility model is related to, belongs to micro mutual inductor neck
Domain.
Background technology
Micro mutual inductor is the conventional electronic equipment of power industry, is generally used among various power instruments, for measuring,
Protection is used.Compared with common transformer, micro mutual inductor has the features such as small volume, precision is high.At present, miniature electric current is mutual
The secondary current coil of sensor, if to reach good insulating properties and pressure-resistant, resistance to elevated temperatures, it is necessary to using cumbersome winding
The technique of insulating tape, it causes production efficiency relatively low, and the mode of insulating tape winding, its pressure-resistant and heat resistance need to be carried
It is high.
The content of the invention
Technical problem to be solved in the utility model is：It is exhausted to provide a kind of micro-transformer of current secondary current coil
Edge external member, it is solved produces the secondary current line of micro-transformer of current by the way of traditional winding insulating tape at present
Circle, causes low production efficiency, and pressure-resistant, resistance to elevated temperatures the asking of needing further to be improved of this micro-transformer of current
Topic.
Technical problem to be solved in the utility model takes following technical scheme to realize：
A kind of micro-transformer of current secondary current coil insulation external member, it includes upper cover body, lower cover, secondary current line
Circle, insulating tape, the upper cover body, lower cover are two structure identical circle lids, during lid portion inside center is provided with
Empty body, the secondary current coil are wound in annular, and upper cover body, lower cover are enclosed on secondary current from above-below direction respectively
On coil, upper cover body, the body of lower cover insert in secondary current coil respectively, by the body that communicates up and down by upper cover body,
Lower cover end is run through, and the lead-out wire of secondary current coil is drawn in being stitched from upper cover body, lower cover, with insulating tape in middle seam
The upper circle of winding one, so as to which the lead-out wire three of upper cover body, lower cover and secondary current coil is fixed.
As preferred embodiment, the upper cover body, lower cover use the plastic material of good insulating.
As preferred embodiment, the height of the body is less than or equal to lid height, with ensure upper cover body, lower cover can on
Under be harmonious.
The beneficial effects of the utility model are：Directly it is linked on secondary current coil using upper cover body, lower cover so that
Secondary current coil is completely enclosed within insulation external member, is overcome the cumbersome technique of traditional wound insulating tape, is substantially increased
Production efficiency；Upper cover body, lower cover use the plastic material of good insulating simultaneously so that secondary current coil has superpower resistance to
Pressure and heat resistance.
Brief description of the drawings
Fig. 1 is upper cover body, the structural representation of lower cover in the utility model；
Fig. 2 is the overall structural representation of the utility model.
In figure：Upper cover body 1, lower cover 2, secondary current coil 3, insulating tape 4, body 5, lead-out wire 6.
Embodiment
In order to be easy to understand to technological means of the present utility model, creation characteristic, reached purpose and effect, tie below
Conjunction is specifically illustrating, and the utility model is expanded on further.
As Figure 1-Figure 2, a kind of micro-transformer of current secondary current coil insulation external member, it include upper cover body 1, under
Lid 2, secondary current coil 3, insulating tape 4, upper cover body 1, lower cover 2 are two structure identical circle lids, in lid
Portion center is provided with hollow body 5, and secondary current coil 3 is wound in annular, and upper cover body 1, lower cover 2 are respectively from upper and lower
Direction is enclosed on secondary current coil 3, and upper cover body 1, the body 5 of lower cover 2 are inserted in secondary current coil 3 respectively, by upper
Under the body 5 that communicates upper cover body 1, the end of lower cover 2 are run through, the lead-out wire 6 of secondary current coil 3 is from upper cover body 1, lower cover
Drawn in being stitched in 2, the circle of winding one is sewed in insulating tape 4, so as to by upper cover body 1, lower cover 2 and secondary current coil 3
The three of lead-out wire 6 fix.
Upper cover body 1, lower cover 2 use the plastic material of good insulating.
The height of body 5 is less than or equal to lid height, to ensure that upper cover body 1, lower cover 2 can be harmonious up and down.
Directly it is linked on secondary current coil 3 using upper cover body 1, lower cover 2 so that secondary current coil 3 is complete
It is enclosed in insulation external member, overcomes the cumbersome technique of traditional wound insulating tape, substantially increase production efficiency；Upper cover body simultaneously
1st, lower cover 2 uses the plastic material of good insulating so that secondary current coil 3 has superpower pressure-resistant and heat resistance.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, do not depart from the utility model spirit and
On the premise of scope, the utility model also has various changes and modifications, and these changes and improvements both fall within the utility model will
In the range of asking protection.The utility model requires protection scope is by appended claims and its equivalent thereof.
