Description

Technical Field

[0001] The utility model relates to a low-resistance test adapter device for a multi-core line-swinging connector. Background Art

[0002] Connector on-resistance test is an indispensable part of cable product acceptance inspection. The inspection of cable products requires operators to test point by point according to technical documents and make judgments point by point. The inspection efficiency is low and the influence of unstable factors such as human factors cannot be avoided. Since manual point-by-point testing is very slow and inefficient, the wiring relationship is difficult to check and the test data is difficult to collect, the on-resistance test of the connector has always been a difficulty that plagues production and inspection.

[0003] Therefore, it is necessary to develop a switching device that can quickly and accurately access multi-core wire connectors and perform low resistance testing. Summary of the invention

[0008] The supporting long plate is fixed on the bottom plate through the rib plate and is located above the sliding body assembly;

[0009] The vertical quick clamp is installed on the supporting long plate and is located above the wire crimping end assembly;

[0010] The wire-slip connector product is installed on the wire-pressing end assembly; the elastic pin is installed on the sliding body assembly.

[0011] In the above technical solution, there are one or more groups of low-resistance test adapter structures for multi-core drop-line connectors.

[0012] In the above technical solution, the sliding body assembly includes a pin fixing seat, a slider, and a miniature linear guide rail; the pin fixing seat is located on the slider; the slider is located on the miniature linear guide rail; the pin fixing seat is slidably connected to the miniature linear guide rail through the slider;

[0013] The miniature linear guide is mounted on the base plate;

[0014] The pin fixing seat is L-shaped; an elastic pin hole is arranged on the vertical end of the pin fixing seat; and the elastic pin is installed in the elastic pin hole;

[0028] (1) The crimping seat adopts a floating crimping cover. When the wire is inserted, the crimping cover will temporarily press the wire to prevent the wire from escaping from the crimping base, making operation easier;

[0029] (2) The contact pin is an elastic pin, and the needle head of the elastic pin is spherical. Under the premise that the wire is not installed neatly, it can also ensure that each core of the wire is in reliable contact with the elastic pin, thereby ensuring the accuracy of the test;

After the test is completed, the damaged part must be removed, causing resource waste and increasing product costs; the adapter device described in the utility model transfers the swing wire connector to a multi-channel low-resistance test instrument. After connection, it can realize independent automatic measurement of multiple loops, improve test efficiency, and save labor costs (the adapter device described in the utility model can complete the low resistance test of the multi-core swing wire connector by only one person, and the detection efficiency is about 5 times that of manual labor); it overcomes the problem that the existing manual detection requires at least 2 people, and a single test is performed on each loop, and the manual point-by-point test is slow and inefficient;

[0032] (5) The utility model adopts the on-resistance test of the swing-wire connector. The operator only needs to put the swing-wire connector to be tested into the adapter according to the serial number. After connection, multiple circuits can be measured independently and automatically. The operator relies on the wire number tube at the end of the swing-wire connector to distinguish the serial number, and the accuracy of wiring relationship confirmation reaches 100%. It solves the problem of complex wiring relationship, difficult inspection and difficult collection of test data in the on-resistance test of the swing-wire connector.
