Description
Technical field
The utility model belongs to electric leakage protection technology field, and in particular to a kind of RCD modules.
Background technology
Common household and the residual current protecting electric appliance of similar site currently on the market（Hereinafter referred to as RCD）,
The electricapparatus circuit of the trial jump module of module section（Secondary circuit）Break-make mode mainly pass through elastic contact chip（Copper
Piece/spring）Division is realized, relatively common in the product of positive inlet wire.With the increasingly variation of product field of employment, especially
In new energy industry, it is desirable that product, which preferably uses, to be had the function of to pour line into, reach the safety of cabling inside equipment, stability and
Clear clean and tidyization, while saving the use of cable wire.
Most products in the market are not exclusively supported to pour line into, because the structure of module limits the function of product.Separately
One is supports to pour line into, but in new national standard（GB/T 16917.1-2014）Implementation procedure in（Especially three-phase takes electric production
Product）, tentative module circuit generates high voltage in wiring board in break-make, causes the contact chip of elasticity（Copper sheet/spring）In division
During it is exothermic melting, caused by poor contact, cause properties of product to fail.
Invention content
It generates heat melt in use technical problem to be solved by the utility model is to provide a kind of avoidable contact chip
The band of change pours the RCD modules of line defencive function into.
In order to solve the above technical problems, the utility model is achieved through the following technical solutions：A kind of band pours line into
The RCD modules of defencive function, including quiet contact plate, contact chip and connecting rod, contact chip top are fixed on casing, and connecting rod is rotatable
Ground is set to the lower section of contact chip, and the lower end of contact chip is connected to electrical contact, and connecting rod is equipped with the end of a protrusion, when RCD modules are closed
When lock, connecting rod rotates counterclockwise, and the projecting ends of connecting rod resist contact chip and contact chip is made to be folded upward at, on contact chip lower end
Electrical contact contacted with quiet contact plate.
Further, contact chip is equipped with a bending part, the bending part of the projecting ends imbedding and contact on piece of connecting rod when combined floodgate
It is interior.
Further, the middle part of contact chip is laterallyd secure by fixinig plate on casing.
The utility model is beneficial in that the circuit connecting mode of the utility model can be such that the entire of RCD modules returns
Effective internal resistance value on road reduces, and under its normal operation circumstances, is effectively reduced Wen Sheng, reduces power consumption, while ensure that circuit
Thermal stability, so that circuit is not fused because of high voltage.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Wherein：1, linkage mechanism；2, connecting rod；3, contact chip；4, quiet contact plate；5, electrical contact；6, shell boss；7, axis；8
Locating piece.
Specific implementation mode
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments：
As shown in Figure 1, the top of contact chip 3 is fixed, the middle part of contact chip 3 is fixed by locating piece 8, the lower part of contact chip 3
Equipped with a bending part, the lower end of contact chip 3 is equipped with electrical contact 5.Linkage mechanism 1 is located at the side of RCD modules, linkage mechanism 1
Connecting rod 2 with axis 7 be rotating shaft, connecting rod 2 is equipped with the end of a protrusion, is located at the lower section of the bending part of contact chip 3.
In making process, linkage mechanism 1 drives connecting rod 2 to be rotated counterclockwise for rotating shaft with axis 7, the end insertion of connecting rod 2
In the bending part of contact chip 3, contact chip 3 is made to be folded upward at, the electrical contact 5 of 3 lower end of contact chip is contacted with quiet contact plate 4, is connect
Touch block circuit is connected.Contact chip 3 bending part bend deform, therefore contact chip 3 during being folded upward at can avoid with
Shell boss 6 contacts, and ensures between electrical contact 5 and quiet contact plate 4 there is enough pressure.Locating piece 8 laterallys secure contact chip 3, prevents
Only 3 stress displacement of contact chip.
The circuit connecting mode of the utility model can be such that effective internal resistance value in the entire circuit of RCD modules reduces, its just
Under normal working environment, it is effectively reduced Wen Sheng, power consumption is reduced, while ensure that the thermal stability of circuit, makes circuit will not be because of pole
High voltage and fuse.The utility model band pours line defencive function into, is particularly suitable for being applied to more demanding to wire leading method
In circuit system, such as in photovoltaic and wind-powered electricity generation new energy resources system.
It is emphasized that：The above is only the preferred embodiment of the present utility model, not appoints to the utility model
What formal limitation, any simple modification made by the above technical examples according to the technical essence of the present invention, etc.
With variation and modification, it is still within the scope of the technical solutions of the present invention.
