压接是一种永久性连接方式。所谓压接，就是连线端的金属导线筒包住裸导线，用手动或自动的专用压接工具对导线筒进行机械压紧而产生的连接。它是让金属在规定的限度内发生变形将导线连接到接触件上的一种技术。好的压接连接存在金属互溶流动，使绞合导线和接触件材料对称变形。这种连接是一种冷焊连接，可得到好的机械强度和电连续性。
Crimping is a permanent connection. The so-called pressing connection is the connection of bare conductor wrapped by metal conductor barrel at the end of the connection and mechanical compression of the conductor barrel by manual or automatic special pressing tool. It is a technology that allows metal to deform within specified limits and connect wires to contacts. A good crimping connection exists metal miscible flow, which makes the twisted conductor and contact material symmetrical deformation. This connection is a cold welding connection, which can obtain good mechanical strength and electrical continuity.
