At present, the connection between the lead wire terminal and the ground bar of the external electrical equipment is usually arc welding. The utility model patent of China Authorized Notice No. CN202172131U discloses a conductive connecting plate for lead wires. The conductive connecting plate includes a fastening plate and a connecting pipe for leading wires. There is a notch on the upper end surface of the fastening plate, and the leading wire connecting pipe is inserted into the notch of the fastening plate for welding. Although the connection between the terminal and the lead wire is firmly welded, there are some shortcomings. 1. The fastening plate, that is, the terminal is flat, and the terminal is provided with a connection hole connected to the grounding bar of the equipment. The terminal after welding must be It is on the same plane as the grounding bar of external electrical equipment, so the terminal block is directional, which makes it difficult to connect in any direction between the terminal block and the grounding bar of external electrical equipment. 2. During the test work, the terminals cannot be disassembled, which brings inconvenience to the test work.

There is a central hole on the bottom surface of the steel cylinder, and the terminal uses the central hole to cover the lead wire. The steel cylinder of the terminal is provided with external threads, and a nut that is set on the lead wire is threadedly connected to the steel cylinder of the terminal. Above, the lower part of the inner hole of the nut is tapered, and there are three grasping claws between the nut and the lead wire.
所述接线端子的钢质矩形板和钢质圆柱是一体的。The steel rectangular plate and the steel cylinder of the connection terminal are integral.
所述接线端子的钢质矩形板上设有两连接孔，分别为圆孔和腰形孔。The steel rectangular plate of the connecting terminal is provided with two connecting holes, which are respectively a round hole and a waist-shaped hole.
引上线由钢质芯棒以及紧密包裹其外围的不锈钢包覆套组成。The lead wire is composed of a steel mandrel and a stainless steel sheath that tightly wraps its periphery.
本发明具有如下积极效果：1、本发明由螺母把引上线和接线端子固定在一起，借助一般普通工具就可以连接，所以降低对施工工具的要求，由于采用螺纹连接，装拆方便，使接线端子能任意改变安装方向，实现与外部电气设备接地排任意方向的快速便捷连接，而且又方便试验工作。2、由于螺母内具有带锥度抓紧三爪，能保证连接的可靠性。3、接线端子利用中心孔套在引上线上，引上线的端面被接线端子所遮盖，所以能防止引上线的端面因裸露而受到环境的腐蚀。4、接线端子不需要进行表面防腐处理。5、由于不需要在施工现场进行焊接，消除因焊接存在的安全隐患。The present invention has the following positive effects: 1. The present invention fixes the lead-in wire and the connecting terminal together by a nut, which can be connected with common tools, so the requirements for construction tools are reduced. Due to the threaded connection, the assembly and disassembly are convenient, making the wiring The installation direction of the terminal can be changed arbitrarily, so as to realize the fast and convenient connection with the grounding bar of external electrical equipment in any direction, and it is also convenient for the test work. 2. Since there are three claws with taper in the nut, the reliability of the connection can be guaranteed. 3. The connecting terminal uses the central hole to cover the lead-in wire, and the end face of the lead-in wire is covered by the connecting terminal, so it can prevent the end face of the lead-in wire from being corroded by the environment due to exposure. 4. The terminal does not need surface anti-corrosion treatment. 5. Since welding is not required at the construction site, potential safety hazards due to welding are eliminated.
