Use of terminal

Terminals are used to facilitate the connection of wires. It is actually a piece of metal wrapped in insulating plastic, with holes at both ends for inserting wires and screws for fastening or loosening. For example, two wires sometimes need to be connected and sometimes they need to be disconnected. At this time, they can be connected through terminals or disconnected at any time without welding or winding together, which is very convenient and fast.

In addition, it is suitable for the interconnection of a large number of wires. There are special terminal boards and junction boxes in the power industry, which are all terminal blocks, single-layer, double-layer, current, voltage, ordinary, fragile and so on. A certain crimping area is to ensure reliable contact and sufficient current.

Extended data

According to the functions of terminals, such as common terminals, safety terminals, test terminals, grounding terminals, double-layer terminals, double-layer conductive terminals, three-layer conductive terminals, one-in and two-out terminals, one-in and three-out terminals, two-in and two-out terminals, circuit breaker terminals, overvoltage protection terminals, sign terminals, etc.

According to the classification of current, it can be divided into ordinary terminals (small current terminals) and large current terminals (above 100A or above 25MM line).

According to the appearance classification, it can be divided into rail terminals (such as JH 1, JH2, JH5, JH9, JY 1, etc. ) and fixed terminals (such as TB, TC, X3, X5, H series, JQH8- 12, JQH8-65438+).
