Description
Technical field
The utility model is related to transformer technical fields, especially button-type open-close type low-voltage current mutual inductor.
Background technology
Current transformer is applied among automation control area, for detecting electric current.Traditional current transformer closes
Mouth formula structure before detection is installed, needs to dismantle busbar, and installation is often inconvenient, meanwhile, in order to ensure safety when installing
Property, it is also necessary to it is cumbersome dump.
Utility model content
The utility model is directed to deficiency of the prior art, provides button-type open-close type low-voltage current mutual inductor,
It does not need to cut off the power during installation, it is simple in structure, simple and convenient, easy for installation.
In order to solve the above technical problems, the utility model is addressed by following technical proposals：Button-type open-close type is low
Voltage current transformer including the upper shell and lower housing being mutually rotatablely connected, is provided with No.1 iron core in the upper shell, described
Connecting hole is offered on the correspondence face of upper shell, button block is slidably connected on each connecting hole, it is described to press
Button block and the clamping piece being slidably connected in the upper enclosure inner wall are connected；
No. two iron cores coordinated with the No.1 iron core are provided in the lower housing, meanwhile, it is set on the lower housing
It is equipped with the buckle with the clamping piece cooperation clamping.
In above-mentioned technical proposal, it is preferred that several connection sheets are provided on the upper shell, in each connection sheet
Offer card slot.
The beneficial effects of the utility model are：The utility model does not need to cut off the power when mounted, simple in structure, operation
It is simple and convenient, easy for installation.
Description of the drawings
Fig. 1 is utility model diagram.
Fig. 2 is the utility model internal structure schematic diagram.
Fig. 3 is the utility model lower housing schematic diagram.
Fig. 4 is clamped piece schematic diagram for the utility model.
Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings：Referring to Fig. 1-Fig. 4, press
Button type open-close type low-voltage current mutual inductor including the upper shell 1 being mutually rotatablely connected and lower housing 2, is set in the upper shell 1
There is No.1 iron core 11, connecting hole is offered on the correspondence face of the upper shell 1, each slip connects on the connecting hole
Button block 3 is connected to, the button block 3 is connected with the clamping piece 4 being slidably connected on 1 inner wall of upper shell, meanwhile,
Spring is provided between clamping 1 inner wall of piece 4 and upper shell, can be automatically reset convenient for clamping piece 4 and button block 3.
No. two iron cores 21 coordinated with the No.1 iron core 11 are provided in the lower housing 2, meanwhile, in the lower housing
The buckle 22 with the clamping piece 4 cooperation clamping is provided on 2.
Several connection sheets 12 are provided on the upper shell 1, card slot 13 is offered in each connection sheet 12.
Meanwhile the through-hole 41 coordinated with the button block 3 is offered on the clamping piece 4, in the through-hole 41
Several grooves 42 are offered on wall, film packet is both provided in each groove, glue is filled in each film packet
Water, the film packet are interference fitted with the groove, meanwhile, film packet 2/3rds is located in the groove, 1/3rd
In outside the groove.When button block is encased in clamping piece, the film packet on through-hole wall is racked, the glue in film packet
Water is flowed between button block and through-hole wall, so that being quickly and effectively fitted close between clamping piece and button block.
Before use, by button block, up case inside presses so that clamping piece is detached with buckle, and after separation, upper shell is whole
Body can be rotated along lower housing, and No.1 iron core is detached with No. two iron cores after rotation, then carries out current sensing operation.
Above example is only to illustrate the technical solution of the utility model, rather than its limitations；Although with reference to aforementioned 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 replacement to which part technical characteristic；And these
Modification is replaced, the spirit and model of various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution
It encloses.
