Tensile test device

Abstract

The invention provides a tensile test device for tensile test of binding strength between an electronic component body and a pin. The device comprises a base, a push and pull dynamometer, a rack and a fixture. The base comprises a support frame and an installation part; the push and pull dynamometer is mounted on a mounting portion and contains an extension part; the rack is connected to the extension part, and is used for hanging the body and towards the exposed pin on the base; and the fixture is arranged on the base, right opposite to the rack and for clamping the pin. The invention can avoid electronic component body deformation caused by a known tensile test device and eliminate complex steps of welding and welding removal of the pin and a test wire, and can solve problems caused by component force in the test, thereby having the advantages of convenient operation, stable test process, improvement on test efficiency and reliability.

Description

technical field [0001] The invention relates to a tensile test device, in particular to a tensile test device for combining strength of a body and pins of an electronic component. Background technique [0002] Currently commonly used electronic components usually have a body and pins connected to it (also known as pins, lead wires, guide pins, cathode / anode terminals or cathode / anode wires), such as resistors, capacitors, inductors, diodes, and transistors. The pins are used to electrically connect the body of the electronic component and the circuit board; wherein, the bonding strength between the body of the electronic component and the pins affects the stability of the electrical connection of the circuit board, thereby affecting the overall use and quality of the electronic product. Therefore, in the manufacturing process of various electronic components, pin strength tensile tests must be carried out to achieve product requirements or verification standards that the bod...

Problems solved by technology

[0005] However, the known tensile test device 1 must weld the pin 104 and the test lead 110 before performing the tensile test, which will cause thermal stress inside the pin 104 and have a negative impact on the material strength of the pin 104 itself; and When performing a tensile test, the clamping action of the fixture 15 to fix the body 102 will also cause external stress, causing the body 102 to be deformed under pressure, resulting in damage to the appearance, and more likely to damage the internal structure; , locking degree and position are not quantified, so that the parameters of each test are inconsistent, thereby affecting the test results; It cannot be parallel to the initial upright direction of the pin 104, so the pulling force is not completely applied to the electronic component 100, and it is hung on the push-pull gauge 20 by the hook portion 112 at one end of the test lead 110, when the main body 102, When the position of the pin 104, the test lead 110 and the hook 112 are not in a straight line, it will affect the direction of the applied pulling force and lead to the generation of non-vertical component force

[0006] Therefore, the above-mentioned known tensile test device will damage the appearance of the electronic component to be tested, and the result will be affected due to the generation of the component force of the tensile force, and the process will be cumbersome and inconvenient, resulting in poor efficiency; therefore, a convenient operation, testing process A stable and reliable pin pull test device is necessary to improve the efficiency of the production process and product quality
