Description
Technical field
The invention belongs to electric parameter metering technical field, particularly relate to the vent diverter of a kind of printed circuit board (PCB).
Background technology
Vent diverter is that a kind of power supply being widely used in communication system, complete electronic set, Automated condtrol etc. returns
Lu Zhong, in order to realize current limliting, current-sharing sampling detection device, its according to DC current by resistance time at electricity
Resistance two ends produce the principle of voltage and make.
Fig. 1 a shows in prior art, the side view of application vent diverter on a printed circuit, figure
1b is the front view of Fig. 1 a, as a example by n shape structure.This vent diverter includes resistor disc and in order to even
Connect the dististyle of printed circuit board (PCB), resistor disc as shown in shadeless part A, the B that dististyle is the most hatched
Shown in part.Wherein, resistor disc uses copper-manganese to make, and in order to reduce contact resistance and temperature drift, dististyle is adopted
Make by red copper, i other words, this splitter is to be welded by copper-manganese and red copper, rather than one-body molded.
Therefore, the vent diverter of above-mentioned printed circuit board (PCB) that prior art provides has the disadvantage that one, manganese
Copper and red copper are due to reasons such as techniques in welding process, and the resistance of the vent diverter made is relative to design load
Can there is certain deviation, this is accomplished by after vent diverter is made, and vent diverter is carried out resistance trimming so that
The long processing time of vent diverter, average product are low, and then improve production cost；Two, to making
When vent diverter carries out resistance trimming, resistance can only be tuned up due to the existence of dististyle, it is impossible to turn down, application spirit
Activity is poor.
Summary of the invention
The purpose of the embodiment of the present invention is to provide the vent diverter of a kind of printed circuit board (PCB), it is intended to solve existing
The vent diverter of the printed circuit board (PCB) that technology provides is to be welded by copper-manganese and red copper, needs dividing of making
Fluid element carries out resistance trimming so that long processing time, average product are low, production cost is high, and resistance cannot be adjusted
Big problem.
The embodiment of the present invention is achieved in that the vent diverter of a kind of printed circuit board (PCB), described vent diverter
Formed by strip metal bending tablet, on described strip sheet metal relative to the first end and the second end have to
A few gap so that described first end be divided at least one first kind pin and at least one second
Class pin, described second end is divided at least one the 3rd class pin and at least one the 4th class pin, and
The width of described first kind pin is more than the width of described Equations of The Second Kind pin, and the width of described 3rd class pin is big
Width in described 4th class pin；
Described first kind pin and described 3rd class pin are for the current sample respectively as described vent diverter
Pin connects printed circuit board (PCB), described Equations of The Second Kind pin and described 4th class pin for respectively as described point
The voltage sample pin of fluid element connects described printed circuit board (PCB).
The vent diverter of the printed circuit board (PCB) that the embodiment of the present invention provides is by the one-body molded processing of strip sheet metal
Form, simple in construction, it is to avoid the resistance deviation that in prior art, copper-manganese and red copper produce in welding process,
Thus without manufactured goods being carried out resistance trimming so that processing procedure is simplified, and shortens Product processing duration, improves
Average product, and then the artificial and cost of material can be saved, and the production cost of 50% at least can drop；With
Time, owing to decreasing piece portion relative to existing vent diverter, thus can be according to actual needs to resistance
Tuning up or turn down, motility is strong；Further, since the welding of copper-manganese and red copper is to use in prior art
Stannum is as medium, and the temperature drift coefficient of solder is compared less stable, and the embodiment of the present invention is without weldering

It is identical with embodiment one that resistance carries out tuning up or turning down process, resistance trimming principle and mode, is not repeated herein.
The vent diverter of the printed circuit board (PCB) that the embodiment of the present invention four provides is one-body molded by strip sheet metal 4
Process, simple in construction, it is to avoid the resistance that in prior art, copper-manganese and red copper produce in welding process
Deviation, thus without manufactured goods being carried out resistance trimming so that processing procedure is simplified, and shortens Product processing duration,
Improve average product, and then the artificial and cost of material can be saved, and at least can drop the production cost of 50%；
Simultaneously as decrease piece portion relative to existing vent diverter, thus can be according to actual needs to resistance
Value tunes up or turns down, and motility is strong；Further, since the welding of copper-manganese and red copper is to adopt in prior art
With stannum as medium, the temperature drift coefficient of solder is compared less stable, and the embodiment of the present invention four nothing
Need welding sequence, there is the advantage that temperature drift is little.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all at this
Any amendment, equivalent and the improvement etc. made within bright spirit and principle, should be included in the present invention
Protection domain within.
