The wires inside the side terminal conduit are connected in the junction box, and the wires in the crimping frame are tightly attached to the conductor and clamped at the end. Instead of welding them together or wrapping them together, and making sure they pass through the current they need.

In order to ensure that the electric fuel pump of the EFI engine works only when the engine is working and avoid misoperation, the control switch of the electric fuel pump is installed in the vane air flow sensor. Only when the engine is changing and there is air flowing into the air flow sensor, the switch of the oil pump is closed, and then the fuel pump works. When the engine stops changing, even if the incineration switch is turned on, the vane of air flow sensor will not change, and the oil pump will not work. A certain crimping area is to ensure firm touch, and to ensure that the current can pass through. Generally, all the UK series universal UK side terminals in the specification can be used in the eexe category of the en50019 specification. The corresponding ex ex explosion-proof authorized component certification number can be found under the wiring data, which is similar to the sister type with smaller boundary dimension of the thinner conductor, and the external dimension of the terminal with the cross section of the conductor larger than 6mm2 is also optimized. The terminal has a universal device foot, so it can be installed on the U-shaped guide rail ns35 and G-shaped guide rail ns32. The closed screw guide hole ensures ideal screw operation. Terminals of multiple section levels are equipped with consistent accessories, such as end plates, grouped partitions, and so on.

In this way, different degree of thermal expansion can be avoided due to the difference of thermal expansion coefficient of data, so mechanical stress can be avoided in the terminal and loosening of connection can be avoided. Use "reakdyn principle" to avoid self loosening of terminal screws. In the preferred terminal series with additional section up to 10mm2, the wire pressing frame adopts the lifting cylinder layout. Their effect principle is based on the so-called "lifting cylinder principle". When the screw is tightened, the top of the screw is on the conductor, so that the crimping frame moves upward, so that the wire in the crimping frame is tightly attached to the conductor and the end is clamped.

The side terminal is used to facilitate the connection of wires. In fact, it is a piece of metal sheet sealed in insulating plastic. There are holes at both ends that can pierce into the wires. There are screws for fastening or loosening. For example, two wires sometimes need to be connected and sometimes need to be disconnected. This can be connected with terminals and can be disconnected at any time without them It's convenient and fast to weld together. And suitable for a lot of wire interconnection, in the power industry there are special terminal blocks, terminal boxes, which are full of UK side terminals, single-layer, double-layer, current, voltage, general, interruptible and so on. Certain crimping area of UK side terminal is to ensure firm touch and to ensure that it can pass through the satisfied current.
