Description
Technical field
It the utility model is related to, more precisely, being a kind of anti-high-frequency interferencing signal transmission line.
Background technology
Signal transmssion line is all no screen layer in general weighing instrument, then these signal transmssion lines are just into very
Good antenna, receive various mixed and disorderly high-frequency signals in surrounding environment.ADS1230 high accuracy 20 built in KD8127 weighing instruments
Analog to digital conversion circuit, chip inductor (L4, L5), transformer and signal transmssion line easily couple aerial garbage signal and are superimposed upon this
Come on the signal that transmits, or even the useful signal transmitted originally can be changed.It is embodied in：It can not normally demarcate, show after demarcation
Show after overload (OL) and demarcation the abnormal conditions such as data are unstable, have a strong impact on daily weighing precision.
Utility model content
The utility model is mainly to solve the technical problem present in prior art, so as to provide a kind of anti-High-frequency Interference letter
Number transmission line.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：A kind of anti-high frequency is done
Disturb signal transmssion line, including transmission line body, shielded cable layer, magnet ring and band.The weighing and sensing signal wire of transmission line body
Wrapped up by shielded cable layer, the instrument mainboard ground wire of transmission line body is attached to shielded cable layer side, shielded cable layer
One end penetrates 1 or 2 magnet rings, and shielded cable layer is hollow cylinder, and including inner core and outer layer, shielded cable layer is close to instrument
Enter end connector side magnet ring leave 1/4 inner sandwich layer it is exposed outside, and magnet ring both sides are provided with for fixed band.
The weighing and sensing signal line length of the shielded cable layer parcel is 2/3 to the 4/5 of its overall length.
The magnet ring is hollow cylinder, and its inner diameter is equal with the outer diameter of shielded cable layer.
The magnet ring is nickel zinc magnet ring, external diameter 10mm, internal diameter 6.4mm, length 20mm.
Operation principle：When mounted, paste auxiliary fixing card using several strong rubbers and be set in advance in transmission line side to be arranged
To when arrangement transmission line is through fixing card, remote gauge internal transformer and power line adjust magnet ring position, avoid leakage field, treat instrument
After the calibrated data accurate stable of table display screen, the fixing hole of transmission line and fixing card is tightened using band.
Anti- high-frequency interferencing signal transmission line of the present utility model has advantages below：Transmission line of the present utility model is shielding
Cable is penetrated under 1-2 magnet ring effect, makes normal useful signal well by the way that and can suppresses high-frequency interferencing signal well
By, avoid transformer and signal transmssion line from easily coupling aerial garbage signal and be superimposed upon on the signal transmitted originally, protect
Demonstrate,prove weighing precision.
