Description
Technical field
The utility model is related to transformer technical fields, especially low-voltage current mutual inductor.
Background technology
In low-voltage metering mechanism installation process, install low-voltage current mutual inductor and secondary circuit be metrological personnel frequently into
A kind of capable work.At present, have some in the market to the improved low-voltage current mutual inductor of secondary wiring terminals, it will be old-fashioned
The advantages of the shortcomings that binding post is changed to conducting wire and is directly accessed double screws crimping patterns, this kind of low-voltage current mutual inductor is wiring
It is simple and quick, but be exposed to since its pair of screw is lasting outside, when not in use, easily because some are unintentionally collided at double screws
And it damages.
Utility model content
The utility model is directed to deficiency of the prior art, provides low-voltage current mutual inductor, by the way that protection is set to dissipate
Heat structure can not only be effectively protected double screw connecting parts, provide effective heat dissipation channel, promote low-voltage current mutual inductor
Environmental suitability, meanwhile, it is capable to reduce the influence of dust invasion and attack.
In order to solve the above technical problems, the utility model is addressed by following technical proposals：Low-voltage current mutual inductor,
Including mutual inductor body and the base of mutual inductor of the mutual inductor body bottom portion is arranged on, the mutual inductor body, which includes, to be connect
Terminal offers several screw holes on the binding post, and is each equipped with screw in each screw hole, in the binding post
On be equipped with protection radiator structure；
The protection radiator structure includes cover body, radiating piece and fixing piece, is offered and the heat dissipation on the cover body
The No.1 through hole of part cooperation and No. two through holes with fixing piece cooperation, offer cavity body in the radiating piece, described
Cavity body is connected with the No.1 through hole, while the heat dissipation connected with the cavity body is offered on the radiating piece side wall
Mouthful, the fixing piece is connected after passing through No. two through holes with the binding post.
In above-mentioned technical proposal, it is preferred that several fitting grooves are offered on the base of mutual inductor.
The beneficial effects of the utility model are：The utility model protects radiator structure by setting, can not only be effective
The double screw connecting parts of protection, provide effective heat dissipation channel, promote the environmental suitability of low-voltage current mutual inductor, meanwhile, it is capable to
Reduce the influence of dust invasion and attack.
Description of the drawings
Fig. 1 is utility model diagram.
Fig. 2 is the enlarged diagram at D in Fig. 1.
Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings：Referring to Fig. 1 and Fig. 2,
Low-voltage current mutual inductor including mutual inductor body 1 and is arranged on the base of mutual inductor 2 of 1 bottom of mutual inductor body, described
Mutual inductor body 1 includes binding post 3, and several screw holes are offered on the binding post 3, and are filled in each screw hole
Equipped with screw 4, protection radiator structure is equipped on the binding post 3.
The protection radiator structure includes cover body 51, radiating piece 52 and fixing piece 53, offer on the cover body 51 with
The No.1 through hole that the radiating piece 52 coordinates and No. two through holes 54 with the fixing piece 53 cooperation are opened up in the radiating piece
There is cavity body, the cavity body is connected with the No.1 through hole, while is offered and the cavity on the radiating piece side wall
The thermovent 55 of body connection, the fixing piece are connected after passing through No. two through holes with the binding post.
Wherein, radiating piece and cover body are integrally formed.
Several fitting grooves 21 are offered on the base of mutual inductor 2, by setting fitting groove, convenient for mutual inductor entirety and its
The mating connection of his component.
Meanwhile several grooves 22 are further opened on 21 inner wall of fitting groove, each interference is matched somebody with somebody in the groove 22
Conjunction is provided with film bag 23, and film bag three/part is located at outside groove, and 2/3rds parts are located in groove, the film
Filled with glue in bag, and several No.1 protrusions 24 are provided on 23 outer wall of film bag, and in 22 inner wall of groove
On be provided with the No.1 protrusion 24 cooperation No. two protrusions 25, by the cooperation of No. two protrusions and No.1 protrusion, to film
Package position-limiting action.In fitting groove and other respective outer side edges, film bag is squeezed and broken after being squeezed, so that mutual inductance after glue outflow
Device pedestal and other assembling structures closely connect.
Above example is only to illustrate the technical solution of the utility model, rather than its limitations；Although with reference to foregoing reality
Example is applied the utility model is described in detail, it will be understood by those of ordinary skill in the art that：It still can be to preceding
The technical solution recorded in each embodiment is stated to modify or carry out equivalent substitution to which part technical characteristic；And these
Modification is replaced, and the essence of appropriate technical solution is not made to depart from the spirit and model of various embodiments of the utility model technical solution
It encloses.
