a connection terminal

Abstract

The invention provides a connecting terminal, which includes a female end frame and a male end frame. First reed grooves are symmetrically opened on the inner wall of the female end frame to place positive reeds and negative electrode reeds. The boss, the second reed groove is symmetrically opened on the outer peripheral surface of the boss, the first signal reed and the second signal reed are placed, the boss extends out of the journal in the axial direction, and the inner peripheral surface of the journal is opened There is a third reed slot for placing the ground wire reed; the outer circumferential surface of the male end frame is symmetrically opened with the first copper bar slot and the second copper bar slot for placing the positive pre-connected copper bar and the negative pre-connected copper bar. The second copper row groove is used to place the positive electrode copper row and the negative electrode copper row. The inner peripheral surface of the male terminal frame is symmetrically opened with a third copper row groove, which is used to place the first signal copper row and the second signal copper row. The axis position of the male end frame The ground wire pin is fixed, and the connection and disconnection process is realized through the longitudinal movement of the male terminal frame. The arc prevention function is realized by replacing the electronic control signal with mechanical movement, and the structure is simple and low in cost.

Description

technical field [0001] The present invention relates to the technical field of electrical connectors, in particular to a connection terminal that can prevent arcing. Background technique [0002] Hot-plugging (hot-plugging or Hot Swap) means live plugging and unplugging. The hot-plugging function allows users to remove and replace damaged hard disks, power supplies, batteries or boards without shutting down the system or cutting off the power supply. Improve the system's ability to recover from disasters in a timely manner. For electrical interfaces with large currents, during the process of plugging and unplugging, arcing is prone to occur. Traditional arcing prevention is mainly achieved through two aspects: on the one hand, physical arcing prevention, that is, when connecting A physical isolation layer is arranged in front of the pin of the connector to reduce the probability of arcing. The patent number is CN2019212924032, and the name is "An arc-proof pin and electrical...

Problems solved by technology

[0003] The invention provides a connecting terminal, which solves the problem that the protective layer is easy to fail by setting a physical interlayer to prevent arcing; the problem of increasing the production cost due to the need to increase the control program and switch elements to control the arcing through the circuit, through mechanical movement Instead of the electronic control signal to realize the anti-arc function, the structure is simple and the cost is low
