Abstract
The utility model is related to electrical production technical field, title is a kind of mold producing straight-through current transformer, including upper mold and lower mold, has cavity between upper mold and lower mold, has sprue gate and stomata on the upper mold；It is characterized in that：There are multiple screw holes being evenly distributed on the outside of the upper mold or lower mold, also set screw is tightened in screw hole, set screw can head on the current transformer of production this body side surface, the set screw top has acicular texture, such mold has the advantages that, to current transformer ontology accurate positioning, easy to use, also have the advantages that influence properties of product less.
Description
Technical field
The present invention relates to electrical production technical fields, more particularly to the mold of production straight-through current transformer.
Background technology
Straight-through current transformer includes current transformer ontology and the resin layer of outside, produces straight-through current transformer
It needs to use mold, i.e., uses mold when pouring the resin layer of outside outside current transformer ontology.
The mold for producing straight-through current transformer includes upper mold and lower mold, is had between upper mold and lower mold
Cavity；In the prior art, the portion that upper mold and lower mold peripheral do not position current transformer body peripheral
Part has current transformer ontology position inaccurate, and disadvantage inconvenient for use or position location are unreasonable, more influence
Properties of product.
Invention content
The purpose of the present invention provides a kind of to the accurate positioning of current transformer ontology, user aiming at disadvantages mentioned above
Just, properties of product are influenced with the mold of less production straight-through current transformer.
The technical proposal of the invention is realized in this way, a kind of mold producing straight-through current transformer, including upper mold
Tool and lower mold have cavity, have sprue gate and stomata on the upper mold between upper mold and lower mold；Its feature
It is：There are multiple screw holes being evenly distributed, also set screw are tightened on the outside of the upper mold or lower mold in screw hole, position
Screw can head on the current transformer of production this body side surface.
Further speaking, the set screw top has acicular texture.
The beneficial effects of the invention are as follows：Such mold has to current transformer ontology accurate positioning, easy to use
Advantage also has the advantages that influence properties of product less；
The set screw top has acicular texture, also has the electricity in the production straight-through current transformer of production
The few advantage of current transformer ontology exposed position.
Description of the drawings
Fig. 1 is cross section structure schematic diagram when the utility model is used.
Fig. 2 is vertical section structure schematic diagram when the utility model is used.
Wherein：1, upper mold 2, lower mold 3, chamber 4, sprue gate 5, stomata 6, set screw 7, electric current
Mutual inductor ontology 8, pours position at set screw top 9.
Specific implementation mode
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the drawings and the specific embodiments
The present invention is described in further detail.
Fig. 1, the mold of straight-through current transformer, including upper mold 1 and lower mold 2 are produced shown in 2, upper mold and under
There is cavity 3 between mold, there is sprue gate 4 and stomata 5 on the upper mold；It is characterized in that：The upper mold or under
There are multiple screw holes being evenly distributed, also set screw 6 to tighten in screw hole, set screw can head on production and use on the outside of mold
7 side of current transformer ontology.
Current transformer ontology is placed in cavity 3 by the utility model, and current transformer ontology is headed on set screw 6
Lateral surface is positioned, and resin is injected from sprue gate and is poured into a mould, and one-pass molding is arranged mutual in electric current additionally, due to fabrication hole
Sensor lateral surface, it is smaller on the influence of its performance, it is high to insulating requirements because mutual inductor bore section voltage is relatively high, and it is outermost
Edge component voltage is relatively low, and insulating requirements are low.
Further speaking, the set screw top 8 has acicular texture.The exposed portion of current transformer molding in this way
It is point less, it is influenced less.
The foregoing is merely the structure features of specific embodiment of the utility model, but the utility model to be not limited to this,
Any those skilled in the art in the field of the utility model, made by changes or modifications all cover in the utility model
In the scope of the claims.
Claims (2)
1. a kind of mold producing straight-through current transformer, including upper mold and lower mold, have between upper mold and lower mold

A screw hole being evenly distributed, also set screw are tightened in screw hole, and set screw can head on the current transformer sheet of production
Body side surface.
2. straight-through current transformer according to claim 1, it is characterized in that：The set screw top has needle-shaped
Structure.
