Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of finished wire material testing, in particular to a wire material conductivity testing box. Background Art
[0002] In the prior art, when making various types of equipment, various wires are indispensable, including communication wires, power wires, signal wires, data wires, control wires, etc. These wires connect various components of various devices, such as the display needs a video cable to connect to the host, and the host needs a communication cable to connect to the network, etc. The interfaces of various parts of the equipment are different, some use DB type interfaces, some use aviation plugs, some have three pins and five pins, etc., so these wires need to be installed with different connection plugs when connecting various parts of the equipment. We need to produce these wires in the process of producing equipment, and these wires are made of wire raw materials after cutting and installing connection plugs. The quality of these wires is directly related to the quality of the entire equipment. If the wires are not up to standard, the entire equipment will have problems. If it cannot be conducted now, or the conductivity is not good, it may cause serious accidents, so it is particularly important to inspect the finished wires.
[0003] At the same time, in mass production, due to the strict requirements on production efficiency, the accuracy and convenience of wire inspection become particularly important. Most companies now use the method of connecting the connectors at both ends of the wire to the control box. The control box generates current and flows from one end of the wire to the other end. When the wire is conductive, the LED indicator lights up, and when the wire is not conductive, the LED indicator does not light up.
[0004] The detection device using conventional current excitation and LED indication in the prior art has the following disadvantages:
[0005] 1. Only 1-to-1 pins can be tested, not 1-to-many pins. That is, if one end of the wire is an X-pin terminal, the other end also needs to be an X-pin terminal, and each pin needs to correspond to each other in sequence during production. However, many wires are now made with different numbers of connecting plugs at both ends. One end may have an X pin and the other end may have a Y pin. There may also be a non-one-to-one correspondence between each pin. One pin may correspond to two pins, and two pins may correspond to three pins. Existing detection devices cannot test such wires.
[0006] 2. With the advancement of technology, the number of pins on wires is increasing, with some wires having 50 pins and others having hundreds of pins. The LED switching speed is too slow, and it takes almost 1 second to test each pin. Testing wires with more than 50 pins will greatly affect efficiency. At the same time, the flashing of LEDs will cause visual fatigue to inspectors, who will easily make mistakes and fail to find defective wires, resulting in a decline in overall quality.
[0007] As quality requirements increase, the requirements for the conductivity performance of wires are also increasing. Nowadays, there are strict requirements on the resistance of wires when they are conductive. The simple conduction requirements of lighting up LEDs can no longer meet the current quality requirements. Utility Model Content

[0048] The input module 101 is connected to the test module 103 , and the test module 103 is connected to the wire connection module 102 and the display module 104 .
[0049] The input module 101 includes several function buttons, and the function buttons are operated to complete the input of the properties of the tested wire material through the interface displayed by the display module 104.

[0051] like Figure 3 As shown, the wire connection module 102 includes a replacement interface and multiple single-pin connection terminals 301. The replaceable interface board includes two square openings 302, each with a fixing clip 303 on the left and right sides for installing the replacement socket panel 304.
