可调可锁式交流试验接线插头
摘要：
本发明公开了可调可锁式交流试验接线插头，其特征在于它包括螺帽（1），螺帽（1）内设有可插试验接线的插孔（9），螺帽（1）连接螺杆（2），螺杆（2）的一端设有楔子（8），螺杆（2）外螺纹连接绝缘外套（3），绝缘外套（3）连接可调式插头（4），可调式插头（4）设有插槽（10），楔子（8）插入可调式插头（4）的插槽（10）中，绝缘外套（3）的下端连接可锁卡件（5），可锁卡件（5）连接闭锁头（7），闭锁头（7）通过弹簧（6）与绝缘外套（3）相连，本发明实现试验接线与不同孔径的端子排可靠连接，成本较低，调节容易，缩短工时，提高效率，增强现场校验安全性。
摘要（英）：

The invention discloses an adjustable and lockable alternating-current testing connection plug. The adjustable and lockable alternating-current testing connection plug is characterized by comprising a nut (1), wherein an inserting hole (9) capable of inserting a testing connection line is formed in the nut (1); the nut (1) is connected with a screw rod (2); a wedge (8) is arranged at one end of the screw rod (2); an insulating sleeve (3) is in threaded connection outside the screw rod (2) and is connected with an adjustable plug (4); an inserting groove (10) is formed in the adjustable plug (4); the wedge (8) is inserted into the inserting groove (10) of the adjustable plug (4); the lower end of the insulating sleeve (3) is connected with a lockable retainer (5); the lockable retainer (5) is connected with a locking head (7); and the locking head (7) is connected with the insulating sleeve (3) through a spring (6). According to the adjustable and lockable alternating-current testing connection plug, reliable connection of the testing connection line and terminal strips with different apertures is achieved; the cost is relatively low; adjustment is easy; the working hours are shortened; the efficiency is improved; and the safety of field calibration is strengthened.
