CN203839322U 一种锁扣环 失效 - 权利终止

一种锁扣环
摘要：
本实用新型公开的锁扣环，其长度大于第一预设距离减去0.5厘米得到的差值，并小于第二预设距离；所述第一预设距离为在接线端冒及端盖紧密贴合的状态下，锁扣环销孔到锁扣环凹槽底部之间的最短距离；所述第二预设距离为所述第一预设距离与所述锁扣环的两个直径值之和；相比现有技术中长度比所述锁扣环销孔到锁扣环凹槽底部之间的最短距离还小的锁扣环，本实用新型中的所述锁扣环减小了自身在锁上时所受到的拉力，相应的提高了所述锁扣环的机械强度，避免了现有技术中因锁扣环易断裂而导致高压熔断器故障的问题。
摘要（英）：

The utility model discloses a locking ring. The length of the locking ring is larger than a difference value which is obtained through subtracting 0.5 cm from a first preset distance, and at the same time, the length of the locking ring is smaller than a second preset distance; the first preset distance is a shortest distance from a locking ring pin hole to the bottom of a locking ring groove when a wiring end cap is tightly attached to an end cover; and the second preset distance is the sum of the first preset distance and two diameter values of the locking ring. Compared with a locking ring of which the length is smaller than a shortest distance from a locking ring pin hole to the bottom a locking ring groove in the prior art, a pulling force borne by the locking ring of the utility model when the locking ring is locked can be decreased, and correspondingly, the mechanical strength of the locking ring can be improved, and the problem of high-voltage fuse failure which is caused by proneness to fracture of the locking ring can be solved.
