Wire crimp pull tester

Crimp Pull Tester China Manufacturer and Supplier

Wire Crimp Pull Tester is specially used to determine the pull-off force of various crimped wire terminals, crimped connectors, or wire harness terminals when separated from the wires or cables. It is usually also called the wire terminal pull tester or cable pull tester.

Wire harnesses are widely used in home appliances, automobiles, medical equipment, and other fields. Strictly speaking, any wire terminals or wire harnesses need to be performed the pull test to ensure the product’s reliability. The pull test is a widespread method to determine the quality of wire terminal crimping. Since the pull-off strength of the terminal crimping is affected by the suddenly applied force and the pulling rate, it is usually required to use a constant-rate motorized pull tester to ensure the repeatability of each test result.

There are several different crimp pull test equipment for performing the wire terminal pull test. AMADE develops and produces vertical and horizontal wire terminal pull testers by manual operation and motorized and intelligent wire pull testers in a horizontal structure. The following are the specifications of these wire crimp pull testers.

Summary of Crimp Wire Pull Testers

Although the manual wire crimp pull tester is cheap and simple to configure, the test speed is not controllable due to users’ manual operation on the wheel or lever. The force applied is easy to be changed between different tests and operators, so the results of the manual pull tester measuring the pull-out force of the wire terminal are usually not comparable.

Some wire pull test standards require using a constant-rate cable pull tester to test the pull-off force of crimped wires to ensure the repeatability and reliability of each test result. The only way to achieve the consistency of the wire terminal pull test results is to use the electric/motorized wire pull tester.

The wire crimp pull tester consists of a test bench (test stand), a digital push-pull gauge or force sensor, fixtures. The wire terminal pull test benches produced by AMADE have the Electric (Motorized) test bench, manual test bench, and vertical test bench. The following is the introduction to these several styles of Test Benches.

Electric (Motorized) Test Bench

  • AT-U2-780 & AT-U2- 980 wire crimp pull testers adopt the new structural design.
  • The drive system adopts a speed-adjusting motor, and the wire terminal pulling speed can be adjustable and kept constant during the test procedure.
  • The transmission system features ball screws and polished linear bearings. It has the advantages of good stability, low noise, and convenient operation.
  • The machine can be tested automatically or manually.
  • Equipped with upper and lower limit switches to protect the machine.
  • In addition to configuring the wire terminal fixture, customers can also choose other fixtures to achieve mechanical tests such as tension, compression, and peeling on various materials.

Manual Test Bench

AT-51-A is a horizontal wire terminal tester. The mechanical part adopts a lever handle, which is more convenient and labor-saving in use. The wire terminal can be pulled out by moving the lever handle. The weight of the whole device is only about 11 kg, and its overall size is 450 x 100 x 130 mm. It is an economical wire pull tester.

Vertical Test Stand

AT-U2-70 is a crimped cable pull tester with higher control accuracy than the model AT-U2-51-A. Its test stand is fully enclosed, and its mechanical transmission system adopts precision ball screws and linear guides. The rotation gap is small, so the pulling rate and force control have better stability.

The pulling rate and strength of the wire terminal test are controlled stably by turning the handwheel at a relatively uniform speed, which dramatically improves the precision of the test.

This vertical crimp pull tester has a beautiful appearance, good stability, high test accuracy, small size, and compact structure. It can be placed on the workbench to work.

Digital Push Pull Gauge

  • High precision and high resolution, accuracy up to ± 0.5%.

  • There are two test modes of Peak and Track, with the peak hold function.

  • Three units of N, kgf, lbf are selectable freely.

  • The comparison function and free setting of upper and lower limit deviation values, automatic buzzer sound, and light alarm are used.

  • Memory storage function – 30 sets of test results can be stored.

  • Inductive backlight is available. The switch can be set freely.

  • The display direction of the LCD screen can be reversed.

  • The value can be synchronously displayed on the computer test software through the RS232 or USB cable.

  • Automatic generates the value change curve graphic, and the value can be exported for detailed analysis.
