Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
See Fig. 1, it can be seen that vehicle high-voltage cable self-locking grafting of the present invention is secondary, including the socket 1 being mutually matched and plug 2 from figure.Separately below socket and plug are described.
Socket.Described socket 1 end face has an axial jack 11, and jack 11 inwall is provided with snap lock stop ring annular groove 12, is embedded with snap lock stop ring 13 in snap lock stop ring annular groove 12, and snap lock stop ring is immovable at axis direction in being stuck in annular groove.Snap lock stop ring 13 protrudes from snap lock stop ring annular groove 12 in its natural state, can make a concession under extrusion and return in snap lock stop ring annular groove.Described socket 1 surface is provided with insulation sleeve 14, and the installation that insulation sleeve 14 is externally provided with for fixed in position socket overlaps 15.
The concrete structure of snap lock stop ring 13 can referring also to Fig. 2-Fig. 4, this snap lock stop ring is ring-type around be made as closing by spiral way by conductive wire (actual for beryllium copper silk), be equivalent to existing spring head and the tail close connect formed one ring-type.It is particular in that: 1, the section (the most each spring coil) of snap lock stop ring is not common circle, but the ladder structure of right angle being made up of four edges, see Fig. 4, four edges junction chamfered.Section has, towards plug direction, the guiding hypotenuse (i.e. the hypotenuse waist of right-angled trapezium) that convenient plug passes through, and plug direction has the locking straight flange (i.e. the right-angle side waist of right-angled trapezium) vertical with axis dorsad.2, the described each spring coil of snap lock stop ring tilts an angle the most in the same direction, sees Fig. 2 and Fig. 3, and when by radial pressure, each spring coil angle of inclination increases and internal diameter becomes big, and external force recovers original internal diameter after removing under elastic reaction.
