Joint Assembly and braking vacuum pipe -line system

The utility model provides a joint Assembly and braking vacuum pipe -line system, joint Assembly is including first connecting piece that has the positive pole plug and the second connecting piece that has the negative pole casing, the positive pole plug is pegged graft in the negative pole casing, wherein, be provided with on the negative pole casing and prevent the positive pole plug is deviate from the locking part spare of negative pole casing, just locking part spare with be provided with between the positive pole plug and prevent the positive pole plug is relative negative pole casing pivoted rotation -proof structure. The utility model provides a joint Assembly and braking vacuum pipe -line system, permanent pipe line's trend is avoided because the vacuum line that uncertain rotation in a circumferential direction brought produces the interference with other parts from this better. 本实用新型提供种接头组件及制动真空管路系统，所述接头组件包括具有阳极插头的第连接件和具有阴极壳体的第二连接件，所述阳极插头插接在所述阴极壳体中，其中，所述阴极壳体上设置有防止所述阳极插头脱出所述阴极壳体的锁止部件，且所述锁止部件和所述阳极插头之
