Female terminal with adjustable plugging force

Abstract

The invention discloses a female terminal with adjustable plugging force, which comprises a terminal body, a rectangular tube, a tongue-shaped elastic sheet, a guide mechanism, an abutting mechanism and a locking mechanism, and is characterized in that a segmentation groove is formed in the middle of the upper tube wall of the rectangular tube. The abutting mechanism and the rectangular pipe are integrally formed, the abutting mechanism upwards stretches into an inner cavity of the rectangular pipe, the upper end of the abutting mechanism is lower than the lower end of the tongue-shaped elastic piece, and the upper end of the tongue-shaped elastic piece is higher than the lower end of the locking mechanism. A square tube in an original terminal structure is changed into a rectangular tube, the space in the vertical direction is increased, meanwhile, the guide mechanism is arranged at the penetrating-in end, the abutting mechanism is arranged at the lower end, the locking mechanism is arranged at the penetrating-out end, guiding of the insertion opening in the vertical direction can be achieved through the guide mechanism, and the insertion opening can be locked through the locking mechanism. And the insertion and extraction force on the contact pin is gradually reduced from top to bottom, so that the function of adjusting the insertion and extraction force on the same structure is realized. The device is ingenious in structural arrangement and convenient and efficient to install and use, and the adaptability of multiple application scenes is improved.

Description

technical field [0001] The invention relates to the technical field of connection terminals, in particular to a female terminal with adjustable insertion force. Background technique [0002] In the current technology, the connection of connectors mostly adopts the method of multi-hole integration, which simplifies the connection method of wires and improves the installation efficiency during organization. At present, the known solution is to add a bubble point in the square tube to contact with the round pin or four pins to achieve conduction. After entering the tube, the bubble point of the square tube clamps the pin after rebounding. [0003] Depending on the environment in which the terminals are used, female terminals with different insertion and withdrawal forces need to be set during production, which are divided into low insertion and withdrawal force terminals, medium insertion and withdrawal force terminals and high insertion and withdrawal force terminals. In the...

Problems solved by technology

[0005] However, due to the relatively small structure size of the female terminal, it is difficult to visually distinguish terminals with different insertion and withdrawal forces, which often leads to confusion and use errors, especially on more important instruments or equipment, often resulting in substandard products. Or return to the factory for maintenance, affecting product delivery
