Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of fixture for measuring conductive adhesive tape, comprises insulator foot 1, insulation slide plate 5, screw rod 11, traveller 8, ohmmeter 9, height gauge or vernier caliper 10, lower conducting plate 2 and upper current-carrying plate 7;
For fixed insulation base 1, described traveller 8 also ensures that insulation slide plate 5 is positioned on traveller 8 and slides abreast relative to insulator foot 1, described insulation slide plate 5 coordinates the relative height adjusted between insulator foot 1 and insulation slide plate 5 with described screw rod 11 by screw thread, there is height gauge that zero function precision is more than 0.01mm or vernier caliper 10 for measuring the relative height between insulator foot 1 and insulation slide plate 5, bottom being positioned at lower conducting plate 2 on insulator foot 1 and being positioned at insulation slide plate 5, the upper current-carrying plate 7 relative with lower conducting plate 2 is all electrically connected with the ohmmeter 9 with zero function, during measurement, conductive adhesive tape 3 is placed on lower conducting plate 2.
Insulator foot 1 and insulation both slide plates 5 are fixed by four travellers 8, fixed, insulator foot 1 can not be moved along traveller 8 between insulator foot 1 and traveller 8 by axle sleeve Complete Bind.Insulation slide plate 5 can be limited along traveller 8 up or down by axle sleeve, and four travellers 8 lay respectively at four corner of insulation slide plate 5, guarantee insulation slide plate 5 in the process moved up and down all the time with insulator foot 1 keeping parallelism.The material of described insulator foot 1 and insulation slide plate 5 is bakelite plate or acrylic board.
Insulator foot 1 is mounted with lower conducting plate 2, the surface uniform of lower conducting plate 2 is smooth.Lower conducting plate 2 is installed the subsidiary plate 4 for fixing conductive adhesive tape with penetrating groove.The bottom of insulation slide plate 5 is mounted with insulating stand 6, current-carrying plate 7 on strip insulating stand 6 being installed fixed width or known width.On described strip the installation direction of current-carrying plate 7 and the strip direction of conductive adhesive tape 3 vertical.Namely when clamp conductive adhesive tape 3, make the conducting surface part contact in the horizontal direction of current-carrying plate 7 on the conducting surface of conductive adhesive tape 3 and strip, contact portion is the part that two sides intersects vertically or perhaps overlaps, and can calculate conductive area S=a*b/2 like this according to the known width b of current-carrying plate 7 on the self-conductive width a of conductive adhesive tape 3 and strip.On strip the width of current-carrying plate 7 preferably use 10mm/8mm/2mm or other be convenient to calculate numerical value.On lower conducting plate 2 and strip, current-carrying plate 7 preferably uses the copper coin that electric conductivity is good.
Height gauge or vernier caliper 10 one end of insulator foot 1 and insulation slide plate 5 are fixed on insulator foot 1, using insulation slide plate 5 as the mobile terminal measured.
Screw rod 11 is through insulator foot 1 and insulation slide plate 5, lower end and the insulator foot 1 of screw rod 11 are fixed, when ensureing that screw rod 11 rotates, insulator foot 1 is motionless, insulator foot 1 is vertical with screw rod 11, namely along traveller 8 relative movement, but can mutually can not rotate between insulator foot 1 and screw rod 11 between insulator foot 1 and screw rod 11.Screw rod 11 is vertical with insulation slide plate 5, and the whole external cylindrical surface of screw rod 11 does accurate external thread, and on insulation slide plate 5, screw rod 11 is through the inwall with accurate internal thread.The top of screw rod 11 is the column structure larger than major diameter of thread on screw rod, and annular knurl process is done on column structure surface, makes operator more convenient by rotating screw bolt 11 herein.When rotating screw bolt 11, because of the relation of the threaded engagement between screw rod 11 and insulation slide plate 5, the rotation along with screw rod 11 slowly moves up and down along screw rod 11 by insulation slide plate 5.Wherein, insulating slide plate 5 and being threaded between screw rod 11 can at the five metals nut of embedded one and screw rod 11 threaded engagement that to insulate on slide plate 5.
When measuring, first twisting screw rod 11, making insulation slide plate 5 drive current-carrying plate 7 on strip to move down, until current-carrying plate 7 and lower conducting plate 2 close contact on strip, both height gauge or vernier caliper 10 and ohmmeter 9 are all made return-to-zero simultaneously.
Twisting screw rod 11, insulation slide plate 5 is made to drive current-carrying plate 7 on strip to move up, until can smoothly conductive adhesive tape 3 be placed in subsidiary plate 4, the bottom of conductive adhesive tape 3 fully contacts with lower conducting plate 2, twisting screw rod 11, insulation slide plate 5 is made to drive current-carrying plate 7 on strip to move down, until current-carrying plate 7 and conductive adhesive tape 3 close contact on strip.At this moment can measure the height L of conductive adhesive tape 3 according to height gauge or vernier caliper 10, and highly whether confirmation uses with reality, reads resistance value simultaneously highly identical.
Because conductive adhesive tape 3 is resilient materials, time the short transverse of conductive adhesive tape 3 is under pressure, have twist distortion.When conductive adhesive tape 3 height is at below 3mm, is in use stressed and causes the deformation comparison of distortion little and affect very little on measurement.When conductive adhesive tape 3 highly reaches 5mm or be above time, torsional deformation is just larger on measurement data impact.At this moment the impact that subsidiary plate 4 brings to reduce twist distortion is adopted, ensure that the height of described conductive adhesive tape 2 exceedes the height of described subsidiary plate, and the number percent of the height facing conductive adhesive tape 3 exceeded height is greater than the compression percentages of conductive adhesive tape 3, namely ensure that conductive adhesive tape 2 fully contacts with two surfaces of conducting electricity.
The structure of subsidiary plate 4 as shown in Figure 3, gets the dielectric panel of different-thickness, different according to the thickness of the conductive adhesive tape 3 measured, and dielectric panel does the breach of different width dimensions, and subsidiary plate 4 is in comb teeth-shaped.Described insulating material plate thickness, according to the altitude range of conventional conductive adhesive tape, can be preferred: 3mm, 4mm, 5mm, 6mm, 7mm, 8mm.The gap width of the comb teeth-shaped breach on described dielectric panel determines the width of each breach according to the thickness range of conventional conductive adhesive tape, preferable width: 2.0mm ~ 4mm, every 0.2mm gets a width value.
The conduction impedance data obtain measurement and actual resistance design load compare, and can judge whether the conductive adhesive tape used meets the demands, wherein,
