Charger plug test

Verify the reliability of the charger's service life (plug-in test);

Test conditions: charger; 2000 times; earphone: 1500 times; data cable: 1500 times; 20±10 times/min;

Test equipment: plug-in force testing machine;

Pre-test inspection items: mobile phone comprehensive appearance, structure, function inspection, charger I/O port appearance, function inspection;

testing method:

a. Set the prototype to the power-on state;

b. Plug in the mobile phone and display "plug-in function" until pulling out the mobile phone and display "plug-in function" disappears as a cycle, repeating 2000/1500 cycles;

c. Single-function charger connector: 2000 times of plugging and unplugging, and the display status of the mobile phone should be observed in each cycle; after plugging and unplugging, the structure, function, display and appearance of the prototype should be checked;

d. 2-in-1 charger connector: plug and unplug the charger 2,000 times, and the headset (or data cable) 1,500 times each; observe the display status of the mobile phone in each cycle; display, visual inspection;

e. 3-in-1 charger connector: plug and unplug the charger 2,000 times and the earphone and data cable 1,500 times each, and observe the display status of the mobile phone each time; an examination;

f. Insertion rate: 20±10 times/min;

Inspection standards:

a. Function check: the charging function is normal; making calls, display, ringtone, vibration, keys, speaker, receiver, echo, indicator light, photo, charging, Bluetooth, MINI SD card and other undescribed functions are normal;

b. Structural inspection: there is no abnormality in the prototype structure. The charger plug is free of wear, welding failure, and cracks; the I/O interface is free of wear, tear, and deformation; the pads are free from falling off; the charger plug has normal elasticity and no falling off. The hook of the charger connector has no failure, breakage or breakage, and the charger will not loosen when inserted into the jack of the prototype (it can withstand the weight of the prototype itself); the I/O interface and charger plug have no abnormal feel and other conditions similar to those before the test. inconsistency;

c. Visual inspection: there is no abnormality in the appearance of the prototype, and there is no inconsistency with the state before the test;

The optional equipment for this test is: servo-controlled automatic plug-in force testing machine RS-6600A, mobile phone charger, earphone plug-in test machine RS-6600G, microcomputer plug-in force life test machine RS-8115A

Equipment introduction:

Servo-controlled automatic insertion force testing machine RS-6600A is suitable for insertion force and extraction force test of various connectors. It is equipped with automatic centering device and special fixtures for various connectors to obtain completely accurate insertion force. result. This machine adopts Windows Chinese window program setting, easy to operate, automatically stores test data (load-stroke curve, load decay life curve, test results), and all test conditions can be stored. This machine adopts high-precision load cell measurement and servo motor drive, which can obtain accurate insertion force results.

The mobile phone charger and earphone plug-in test machine RS-6600G can simulate the network card, mobile phone charger, mobile phone headset, stylus, CD/MP3, USB and various connectors and other products for plug-in and pull-out tests to evaluate the structural parts after Whether the quality is reliable after N times of unplugging and plugging.

Microcomputer plug-in force life testing machine RS-8115A is suitable for all kinds of connectors, plugs and sockets to do plug-in and pull-out force life test or pull-out destructive force test for products. The round-trip travel is continuously adjustable, and the test speed is continuously adjustable; the up and down, left and right adjustable clamps are used to ensure the accuracy of the insertion force and solve the problem of unilateral eating, and objectively reflect the insertion and extraction life of the product; a special instrument is used to display the insertion , Real-time pull-out force value, maximum insertion force, pull-out force, and can automatically save 10 sets of test data, and optional micro-printer test results.
