(1a) corresponding position is provided with fixing post (2a), and during installation, fixing post (2a) snaps in circuit board slot (1a) and by the first housing
(1), the second housing (2) is fixed.
Further, described the first housing (1) is additionally provided with the coil groove (1b) for installing coil (3), coil groove
(1b) middle part is additionally provided with through hole, and through hole passes for cable.
Further, online ring recess (1b) the through hole corresponding position of described the second housing (2) is provided with clip (2b), uses
In described novel current transformer is fixed on cable (104).
Further, the free end that described clip (2b) extends to side is without departing from the end face of the second housing (2).
Further, described wiring board (4) is provided with the RJ11 socket connected for signal.
Further, described rail shelves (5) for current transformer is installed on guide rail (101).
Further, described fixed mount (6) for being installed on assembly wall (102) by current transformer.
Beneficial effect: this utility model both can be shelved by mounting rail, again can mounting and fixing support, make current transformer get final product rail
Dress, can fixedly mount again.First housing central section has clip that strapping tape can be used to be directly anchored on cable by current transformer,
Clip is hidden under current transformer end face, is not take up space, makes current transformer have less volume.This Novel electric
Current transformer is installed simple, can realize multiple mounting modes, and volume is little, strong adaptability, uses RJ11 connection can transmit more
Electric information, wiring is the most more convenient and signal polarity will not be occurred to connect anti-phenomenon.

Detailed description of the invention
Below in conjunction with the accompanying drawings, the technical solution of the utility model is preferably described by detailed description of the invention.
As Figure 1-3, a kind of novel current transformer of the present utility model, including with first housing the 1, second housing 2,
Coil 3, wiring board 4, the first housing 1 has circuit board slot 1a, coil groove 1b, mounting groove 1c, the second housing 2 has fixing post
2a, clip 2b.Coil 3 and wiring board 4 are arranged in the first housing 1, and the second housing 2 is removably mounted on the first housing 1
Above and coil 3 and wiring board 4 are fixed.Circuit board slot 1a and fixing post 2a position, quantity are corresponding, during installation, and fixing post 2a
Snap in circuit board slot 1a and first housing the 1, second housing 2 is fixed.Mounting groove 1c shelves 5 or fixed mount 6 for mounting rail；
Being additionally provided with through hole in the middle part of coil groove 1b, through hole passes for cable 104.Clip 2b is located at coil groove 1b through hole corresponding position,
For described novel current transformer is fixed on cable 104, and the free end that clip 2b extends to side is without departing from
The end face of two housings 2.
As shown in Fig. 4 (a), loading in the first housing 1 after first coil 3 and wiring board 4 being connected, wiring board 4 loads line
Road board slot 1a, coil 3 loads coil groove 1b, is then injected into fixing material, such as epoxy resin；Such as Fig. 4 (b), then by the second housing 2
Loading the first housing 1, after epoxy resin fixes material solidification, current transformer completes body and installs.
As shown in Fig. 5 (a), rail is shelved 5 and is loaded in mounting groove 1c by direction as shown, presses Fig. 5 (b) direction dress after installation
Upper rail 101, installation state such as Fig. 5 (c), this is the rail dress mode of current transformer.
As shown in Fig. 6 (a), fixed mount 6 is loaded in mounting groove 1c by direction as shown, presses Fig. 6 (b) and installing after installation
Selecting installation site on wall 102, install screw 103 and load by direction as shown fixing, installation state such as Fig. 6 (c), this is electricity
The fixed installation mode of current transformer.
As it is shown in fig. 7, after cable 104 passes current transformer, binding tools such as band 105 can be used to pass clip 2b
Being fixed on by current transformer on cable 104, clip 2b is hidden under current transformer end face, is not take up space.
As shown in Figure 8, wiring board 4 is provided with the RJ11 socket connected for signal, uses RJ11 plug 106 to realize electrically
