Current transformer has two root bead line such as Fig. 4, it is necessary to weld twice, needs three current transformers to merge one when coordinating with pcb board
Welded after rising, then just need welding 6 times, adjustment position, at corresponding solder joint, be repeated 6 times and align by hand and single
Root manual welding, efficiency are low.
The content of the invention
For deficiency of the prior art, the utility model provides current transformer combination assembling structure, existing to solve
The bonding wire of current transformer need by multiple welding, align by hand and single manual welding, the problem of efficiency is low.
The utility model is achieved through the following technical solutions.
Current transformer combination assembling structure, including three current transformers and PCB main board, integrally set on current transformer
Bonding wire is equipped with, described bonding wire is formed by red line and black line winding, and the bonding wire of three current transformers passes through terminal group component group
Close, described terminal group component includes 6 openings, and described opening is used to accommodate red line or black line, set in described opening
Clamping device is equipped with, described clamping device is elastic card, and the side of described terminal group component is additionally provided with projection, described
PCB main board on set and include locating notch on jagged, described breach, described locating notch and male cooperation.Once
The connection with PCB main board of No. 3 current transformers is can be achieved in operation, and solder joint is concentrated, and realizes rapid welding.
Preferably, described terminal group component includes multiple terminals, described projection is located at the middle of terminal.It is convenient
Positioning, engaging effect are good.
Preferably, the side of each opening is correspondingly arranged on a projection.
Raised cuboid is shaped as preferably, described.Engaging is firm.
Raised hemispherical is shaped as preferably, described.
Preferably, it is provided with attachment means between three current transformers.Attachment means can make it that three electric currents are mutual
Sensor is fixed so that bonding wire assembles more accurate with terminal group component.
Preferably, described attachment means are two-sided tape.
Preferably, described attachment means are buckle.
Preferably, described attachment means are mounting seat and bolt.
Compared with prior art：Voltage x current sampling module needs not move through winding displacement, and sampling is transmitted data to up to mainboard more
Add precisely, winding displacement is changed into copper pin and reduces the manually installed time, extends service life.
Brief description of the drawings

Embodiment
Below in conjunction with the accompanying drawings with embodiment, the utility model is described further.
Current transformer combination assembling structure, including three current transformers 1 and PCB main board 4, one on current transformer 1
Body is provided with bonding wire 2, and described bonding wire 2 is formed by red line and black line winding, it is characterised in that the weldering of three current transformers 1
Line 2 is combined by terminal group component 3, described terminal group component 3 include 6 opening, described opening be used for accommodate red line or
Person's black line, is provided with clamping device in described opening, and described clamping device is elastic card, described terminal group component 3
Side be additionally provided with projection, being set on described PCB main board 4 includes locating notch on jagged, described breach, described
Locating notch and male cooperation, described terminal group component 3 include multiple terminals 31, and described projection is located at the center of terminal 31
Between, side of each opening is correspondingly arranged on a projection, it is described it is raised be shaped as cuboid, described is raised
Hemispherical is shaped as, attachment means are provided between three current transformers 1, described attachment means are two-sided tape, described
Attachment means be buckle, described attachment means are mounting seat and bolt.
In use, first three current transformers 1 it is close to each other or be connected with each other, then arrange 3 groups of welderings
Line 2, it is allowed to be pressed below machine with terminal group component 3, the elastic card of the script of terminal group component 3 is opened, and fills in 3 groups
After bonding wire 2, machine pushes so that elastic card engages 3 groups of bonding wires 2.
After the completion of engaging, as long as terminal group component 3 is fed through in breach corresponding to PCB main board, once-through operation can be real
The connection with PCB main board of existing No. 3 current transformers, and solder joint is concentrated, and realizes rapid welding.
To prevent the carelessness during assembling from causing Current Transformer Secondary side anti-loaded, measurement problem is caused to occur,
So increase salient point simultaneously in the side of terminal group component 3, the locating notch on corresponding pcb board, so as to prevent anti-loaded phenomenon
Occur.
The scope of protection of the utility model includes but is not limited to embodiment of above, and the scope of protection of the utility model is to weigh
