Description

Technical Field

[0001] The utility model belongs to the field of testing, and in particular relates to a connector terminal retention force testing fixture. Background Art

[0002] The connector is a structure for quick connection of circuits. The circuit is turned on by matching the male and female terminals inside the connector. The matching of the male and female terminals utilizes the undercut of the female terminal to hook the boss of the male terminal into position. In the connector, the matching degree of the male and female terminals affects the stability of the connection between the male and female terminals, and the matching degree of the male and female terminals is usually measured by the holding force. When testing the holding force of the connector terminals, the connector is generally tested by pulling in the horizontal or vertical direction. Then the test data is only the holding force in the horizontal and vertical directions. In real life, the angles for pulling out the terminals are not just horizontal and vertical. Therefore, the holding force detection of the connector terminals is not comprehensive enough, resulting in limited detection data. Utility Model Content
