Description
Technical Field
The invention relates to the technical field of resistance electric variable measurement, in particular to a detachable resistance measuring device.
Background
As shown in fig. 1, a conventional resistance measuring device 10 for measuring a resistance electrical variable is shown in an assembled view. Fig. 2 is an exploded view of the resistance measuring device 10 shown in fig. 1. The resistance measuring device 10 includes an outer frame 11 and a measuring jig 12, wherein the measuring jig 12 is detachably mounted on a platform of the outer frame 11.
The resistance measuring device 10 is mainly used for measuring low-resistance customized resistance. The low-resistance customized resistor is small in resistance and large in external interference, and needs to be tested by matching with a special measuring jig so as to ensure the stability and consistency of the test. However, the low-resistance customized resistor has different sizes and shapes, and each product with different sizes needs to adopt a customized measuring jig, the structure of the measuring jig is approximately the same, and only the positions of the measuring probes are different.
When the jig is the whole of fig. 1 and 2, the test jig requires a large amount of storage space and is inconvenient to move; the whole jig needs to be operated during maintenance, so that the operation is inconvenient; when scrapping, the whole jig is required to be scrapped, the cost is high, but only the core test module needs to be replaced in real influence, and the external frame and the movable mechanism are always good, so that waste is caused.
As shown in fig. 3, it is a structural diagram of the measuring jig 12 shown in fig. 2. Since the positions of the test probes 13 on each measurement jig 12 are different, rewiring (or wire bonding) is required each time a new measurement jig 12 is replaced, so that the test probes 13 on the measurement jig 12 are rewired with the wire harness on the platform of the external frame 11, which makes replacement of the new measurement jig 12 extremely complicated and poor in compatibility.
In addition, as can be seen from fig. 3, in the conventional measuring tool 12, the test probe 13 is exposed on the surface of the measuring tool 12, and when the wire harness is connected with electricity, the two hands of the tester easily touch the charged test probe 13, so that potential safety hazards are brought.
Furthermore, as can be seen from fig. 1, in the process of measuring the resistor, the resistor is firstly required to be placed on the measuring jig 12, and then the movable pressing block 14 at the outer frame 11 is pressed down, so that the resistor can be stably contacted with the test probe 13 on the measuring jig 12, and thus, the resistor electric variable can be accurately measured. However, when some testers put the resistor on the measuring jig 12, the movable pressing block 14 at the outer frame 11 is not pressed down, the resistor is already in contact with the test probe 13 and transmits the measurement data to the control center, and the measurement inaccuracy is caused due to the instability of the contact between the resistor and the test probe 13, so that the testers misjudge that the measurement result of the resistor is failed.
