Description
Technical field
The utility model relates to automobile sensor technical field more particularly to a kind of automobile sensor calibrating installations.
Background technique
Current divider is one kind of automobile sensor, and current divider is for measuring DC voltage, when passing through resistance according to direct current
It is made in the principle that resistance both ends generate voltage.In fact, current divider is exactly the resistance of a resistance value very little.It is needing to survey
When measuring biggish DC current, one can be will appear at the both ends of current divider when the DC current of big ampere flows through automobile sensor
At this moment the voltage of millivolt level measures this voltage with millivolt voltmeter, then this voltage is changed using Ohm's law I=U/R
It is counted as electric current, the measurement of high current is completed with this.
Current divider is mainly made of the copperhead of copper sheet and copper sheet two sides, and the two groups of contacts in interior outside are arranged on copperhead.It is shunting
In the Conventional process of device mass, it is desirable that the resistance of all products is that the numerical value when side of standard is qualified.In debugging product
When resistance, the contact in outside is connected to power supply, and the contact of inside is connect with test instrumentation, the then product when the resistance measured is less than normal
It is unqualified；When the resistance measured is bigger than normal, current divider can be removed, the copper sheet of current divider is manually cut with handsaw, with
This increases its resistance value until resistance value is standard figures.
During resistance trimming above, needs manually to carry out the electric connection of two groups of contacts, then tested, for not
Same test result, then release electric connection and product is sorted out.Especially when the resistance measured is bigger than normal, need manually to cut
Copper sheet is cut, is then electrically connected and is tested again, sort out further according to different test results and is debugged again.It is cumbersome,
Low efficiency, it is easy to which when debugging again that original resistance resistance bigger than normal that becomes is less than normal and scrap, the stability of production is low, right
The proficiency and skill requirement of operator is relatively high.
For the defect of above-mentioned traditional handicraft, there are many improved plans, now retrieve one application No. is
CN201410647391.6, the patent of invention of entitled " a kind of correcting device of current divider resistance ".The principle of the patent of invention
Are as follows: the T-type terminals at the both ends of current divider are placed on to the second electrode on piece of support rim, the fixation hole fixation of current divider is matched
Conjunction contacts on positioning pin, and with the third electrode slice in fixed plate, if having gap between third electrode slice and current divider, adds
The conductive spacer for entering appropriate thickness after current divider places, by the jettron of lower cylinder, makes piston rod be connected with first electrode
Piece one end moves downward the T-type terminals up to being pressed into contact with current divider, recloses test switch button at this time, checks galvanometer
Pointer whether nulling if galvanometric pointer is directed toward zero illustrates product qualification, disconnect test switch button and pneumatic at this time
Switch, withdraws the piston rod of cylinder, takes out product and is placed on qualified products set-down location；If galvanometric pointer is directed toward negative
Value, illustrates that product is unqualified, disconnects test switch button and jettron at this time, withdraws the piston rod of cylinder, takes out product
It is placed on substandard product set-down location；If galvanometric pointer is directed toward positive value, illustrate that resistance value is higher, disconnects test at this time and open
Button is closed, corresponding resistor disc is amputated on resistor disc with handsaw, is again started up test switch button, check galvanometric pointer
It is directed toward, until galvanometric pointer is directed toward zero, keeps product modification qualified, press jettron, withdraw the piston rod of cylinder, take
Qualified products out.
The invention effectively simplifies resistance trimming operation, is all once electrically connected, is had to current divider without each resistance trimming
Effect, which is reduced, to be occurred careless omission and leads to underproof product.But there is also defects for the invention, and such as: between contact and current divider
It needs to increase gasket to be adjusted, inconvenient for operation, low efficiency；Internal closed-frame structure, the working space of handsaw are limited；
The tower structure intensity difference, occupied space are big；Cylinder is upper, and when piston is taken exercises downwards, operator is easy to operate by mistake, by hand
Depressed position is put in, there are security risks.
