接线端子是连接电气必不可少的电气配件，通常由绝缘件、导电件、焊脚等部分组成，接线端子是一个工艺性的设计，建议在下面几种情况下考虑使用：

　　The terminal block is an essential electrical accessory for electrical connection. It is usually composed of insulating parts, conductive parts, welding pins and other parts. The terminal block is a technological design, and it is recommended to be used in the following situations:

　　1、该位置的导线因调试、维修等因素，需要频繁拆装导线的。比如两根导线，有时需要连接，有时又需要断开，这时就可以用端子把它们连接起来，并且可以随时断开，而不必把它们焊接起来或者缠绕在一起，很方便快捷。

　　 Due to debugging, maintenance and other factors, the conductor at this location needs to be disassembled frequently. For example, two wires, sometimes need to be connected, and sometimes need to be disconnected, then they can be connected with terminals, and can be disconnected at any time, without welding them or winding them together, which is very convenient and fast.

　　2、一个电气箱或者线路板等等，作为一个整体需要与其他外部电路进行电连接的。将PCB接线端子用于线路板上，在线路出现故障时，可以轻松检测导线，不至于费时费力的将导线从线路板上拆卸。

　　An electrical box or circuit board, as a whole, needs to be electrically connected with other external circuits. When PCB terminal is used on the circuit board, the wire can be easily detected in case of circuit failure, and it will not take time and effort to remove the wire from the circuit board.

　　3、同一处等电位的点需要连接导线数量较多的。接线端子两端都有孔可以插入导线，有螺丝用于紧固或者松开，而且适合大量的导线互联，在电力行业就有专门的端子排，端子箱，上面布满接线端子，单层的、双层的，电流的，电压的，普通的，可断的等等。

　　 At the same equipotential point, more conductors should be connected. There are holes at both ends of the terminal, which can be inserted into the wire. There are screws for fastening or loosening. Moreover, it is suitable for a large number of wires to be interconnected. In the power industry, there are special terminal blocks and terminal boxes, which are covered with wiring terminals, single-layer, double-layer, current, voltage, common, breakable, etc.

　　4、线径较大，不方便与螺钉端子连接的。插拔式接线端子利用压线框接线，可接入大线径，且保护导线不易受损。

　　The wire diameter is large, which is inconvenient to connect with screw terminals. The plug-in terminal block is connected by crimping wire frame, which can be connected to large wire diameter, and the protective wire is not easy to be damaged.

　　5、电流较大，需要增大电连接处接触面积的。TB系列大电流接线端子可满足较大电流连接的需要。

　　 If the current is large, it is necessary to increase the contact area of the electrical connection. TB series high current terminals can meet the needs of large current connection.

　　6、多股导线需要接入同一个端子上的，因同一个接线端子有多个插孔，方便导线接入。

　　 Multiple wires need to be connected to the same terminal, because the same terminal has multiple sockets, which is convenient for wire access.

　　接线端子在连接器领域已经形成了完善的电气接口技术体系，鉴于接线端子的便捷安装和稳定的电气性能，其使用范围也扩大至轨道交通、安防照明、电梯电力控制、医疗器械等多个领域。

　　The terminal block has formed a perfect electrical interface technology system in the field of connector. In view of the convenient installation and stable electrical performance of the terminal block, its application scope has also been extended to rail transit, security lighting, elevator power control, medical equipment and other fields.
