Detailed description of the invention
The present invention is that Combined resistance measures adaptor, by different combinations, can complete the measurement work to different composite material structure on the premise of being changed without low resistance admeasuring apparatus.
The present invention includes fixture, active joint and probe, there is cavity at described fixture center, cavity sidewalls is provided with female thread, active joint size is adaptive with fixture center cavity, and active joint outer peripheral sidewall is provided with external screw thread, active joint is screwed onto in the cavity of fixture, and active joint has the screw run through up and down, probe is screwed onto in the screw of active joint downwards, and the bonding band that probe front contact is to be detected.The present invention has three kinds of deformation, is described separately below:
Copper Foil low-resistance measurement operating procedure:
As shown in Fig. 1 a, b, wherein: 1-fixture and 2-active joint use threaded, 2-active joint and 3-probe use threaded.Owing to Copper Foil uniform spreading is under the multiple sheet material layers in top.3-probe needs guiding through the multiple sheet material layers in top and touches Copper Foil.Just can measure resistance value (the multiple sheet material layers in top is made up of) which floor glass cloth and enamelled coating.So 3-probe front wedge angle should be between 20 ° to 25 °.Owing to 3-probe contact Copper Foil area is little, affecting low-resistance measurement accuracy, so number of probes should be increased, usual number of probes is 8～10.
With hands by 8-low-resistance measurement switching head by composite material surface, adjust 2-active joint to the distance between 8-low-resistance measurement switching head and composite upper surface, it is ensured that the spacing on two sides is 1～2mm.Adjustment 3-probe is to touching composite upper surface, and according to the thickness of the multiple sheet material layers in the top of mark on drawing, binding isotherm one-tenth-value thickness 1/10, swivel feeding 3-probe penetrates composite inner to respective thickness.Probe on low resistance admeasuring apparatus is touched on 2-active joint, read measured value.
Conductive paint low-resistance measurement operating procedure:
As shown in Fig. 2 a, b, wherein: 1-fixture and 4-active joint use threaded, 4-active joint and 5-probe use threaded.Owing to conductive paint even application is under upper paint layer.5-probe needs guiding through upper paint layer and touches conductive paint, just can measure resistance value, and enamelled coating is the thinnest, so 5-probe front wedge angle should be between 100 ° to 120 °.Owing to probe contact conductive paint area is big, all number of probes should be 1.
With hands by 8-low-resistance measurement switching head by composite material surface, adjust 4-active joint to the distance between 8-low-resistance measurement switching head and enamelled coating, it is ensured that the spacing on two sides is 1～2mm.Adjustment 5-probe is to touching upper paint layer, and according to the thickness of the enamelled coating of mark on drawing, binding isotherm one-tenth-value thickness 1/10, swivel feeding 5-probe penetrates inside enamelled coating to respective thickness.Probe on low resistance admeasuring apparatus is touched on 4-active joint, read measured value.
Copper mesh low-resistance measurement operating procedure:
As shown in Fig. 3 a, b, wherein: 1-fixture and 6-active joint use threaded, 6-active joint and 7-probe use threaded.Owing to copper mesh is that network structure uniform spreading is under the multiple sheet material layers in top.7-probe needs guiding through the multiple sheet material layers in top and touches copper mesh.Just can measure resistance value (the multiple sheet material layers in top is made up of) which floor glass cloth and enamelled coating.Owing to copper mesh grid is evenly distributed, for guaranteeing that 7-probe can touch the copper wire on copper mesh, 7-probe should be randomly distributed on 6-active joint.7-probe front wedge angle owing to 7-probe contact Copper Foil area is little, should affect low-resistance measurement accuracy between 25 ° to 30 °, so number of probes should be increased, usual number of probes is 8～10.
Note: for ensureing that 7-probe penetrates the copper mesh net heart, remain to touch copper mesh, and do not destroy copper mesh.Notch can be increased, for excising the multiple material that net is intracardiac, it is ensured that 7-probe contact copper mesh at 7-end of probe.
With hands by 8-low-resistance measurement switching head by composite material surface, adjust the distance between 6-active joint 8-low-resistance measurement switching head and composite upper surface, it is ensured that the spacing on two sides is 1～2mm.Adjustment 7-probe is to touching composite upper surface, and according to the thickness of the multiple sheet material layers in the top of mark on drawing, binding isotherm one-tenth-value thickness 1/10, swivel feeding 7-probe penetrates composite inner to respective thickness.Probe on low resistance admeasuring apparatus is touched on 6-active joint, read measured value.
