Detailed description of the invention
Below in conjunction with accompanying drawing of the present utility model, the technical scheme in this utility model embodiment is clearly and completely retouched
State, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on this
Embodiment in utility model, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of this utility model protection.
As it is shown in figure 1, the open-type current sensor of the present embodiment, it includes first housing the 1, second housing the 2, first iron core
Assembly 3 and the second iron core 4.
With reference to Fig. 5, the first core assembly 3 includes " U "-shaped 31, two skeletons 32 of the first iron core of profile and coil 33,
The two skeleton 32 clamps the first iron core 31 respectively, and coil 33 is set on the first iron core 31 to be located between two skeletons 32.
With reference to Fig. 3 and Fig. 4, the first housing 1 includes the first noumenon 11 and the first lid 12, and the first noumenon 11 is machined with first
Cavity and two grooves, the two groove is through on the thickness direction of the wall body of the first noumenon.First core assembly 3 is loaded on
In one cavity, now the two ends of the first iron core 31 are the most corresponding with the two groove respectively.First lid 12 is placed on the first noumenon
On 11, now the first lid 12 is completely covered by the opening of the first cavity, is fixedly welded on by the first lid 12 with supersonic machine
On the first noumenon.
With reference to Fig. 6 and Fig. 7, the " U "-shaped structure of profile of the second housing 2, it includes the second body 21 and the second lid 22.
Second body 21 is machined with the second cavity that profile is " U "-shaped, and " U "-shaped the second iron core 4 of profile is loaded on this second cavity
In.Being the spring leaf 5 of spring steel equipped with making material between second iron core 4 and the end face of the second cavity, this spring leaf 5 gives the
Two iron cores 4 apply elastic force thus are clamped in the second cavity by the second iron core 4.Second lid 22 is placed on the second body 21
Time, the second lid 22 is completely covered by the opening of the second cavity, with supersonic machine, the second lid 22 is fixedly welded on second
On body 21.
Referring still to Fig. 3, the first noumenon 11 of the first housing 1 is machined with connecting rod 13 and cam 14.Referring still to Fig. 6,
Snap fit 23 and buckle 24 it is machined with on second housing 2.With reference to Fig. 1, and Fig. 2, snap fit 23 catches on connecting rod 13 and buckle 24
Mutually fasten with cam 14 thus the first housing 1 be installed on the second housing 2, now the two ends of the first iron core 31 respectively with
The two ends of the second iron core 4 are corresponding, and the first housing 1 and the second housing 2 form through hole 6, and this through hole 6 is positioned at the first iron core 31
And locate between the second iron core 4.
The principle of open-type current sensor of the present utility model is: snap fit 23 catches on connecting rod 13 and buckle 24 and cam 14
Mutually fasten, thus the most firm primary bus 7 is locked in through hole 6, the most as shown in Figure 2.When primary bus 7 is passed through
Electric current, will produce magnetic loop immediately, and this magnetic loop is coupled in coil 33, and the nearlyest 0 distortion of coil 33 produces signal, should
Signal is transmitted in extraneous demand.
To sum up, open-type current sensor of the present utility model, its first core assembly is fully enclosed in the first housing, and second
Iron core is fully enclosed in the second housing, and therefore the first core assembly and the second iron core are isolated with primary bus completely, even naked
The primary bus of dew, it is also not possible to band supplies electricity to iron core, causes secondary circuit to damage and personal safety, and safety is high；Due to first
Iron core and the second iron core is the most fully enclosed is fixed in the first housing and the second housing, therefore open-type current sensor drop in
During ground, the first iron core and the second iron core are not easily disconnected from the first housing and the second housing, and shock resistance is the strongest.Second iron core and
Between two housings equipped with make material be the spring leaf of spring steel, the second iron core is anchored in the second housing by this spring leaf, and
The performance of spring leaf be difficult to reduce, so can make for a long time the first iron core and the second iron core more can the most corresponding contact, detection performance
Stable, accuracy of detection is high.Further, between one end and second housing of the first housing be flexibly connected, the other end of the first housing and
Mutually fasten between second housing, therefore use and be also convenient for.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all new in this practicality
Within the spirit of type and principle, any modification, equivalent substitution and improvement etc. made, should be included in protection of the present utility model
Within the scope of.
