Specific implementation mode
Embodiments of the present invention are described further below in conjunction with the accompanying drawings.
The specific embodiment of the electric connector accessory of the present invention, as shown in Figures 2 to 5, electric connector accessory includes along preceding
The sleeve 21 that rear direction extends, guiding movement turns be furnished with compression ring 22 in the inner cavity of 21 rear end of sleeve, after being close to compression ring 22
End face is equipped with top-pressure part, and top-pressure part is top pressure ring 23 in the present embodiment, and certainly, top-pressure part, which can also be, is spaced split type top
Casting die.Sealing ring 24 is located between top pressure ring 23 and extrusion ring 25.In use, tightening nuts 26, nut 26 pushes away when moving forward
Dynamic extrusion ring 25, which moves forward, makes its deformation, realization sealing, while top pressure ring 23 by extruding force the application of sealing ring 24 extruding force
It is transmitted on compression ring 22, so that compression ring 22 is radially shunk, clamping cables.
The inner wall of sleeve 21 is equipped with inner conical surface 211, and the front end of compression ring 22 is splitted structure, which forms bullet
The peripheral surface of pawl 221, elastic claw 221 is on same male cone (strobilus masculinus), and the taper of the conical surface of inner conical surface 211 is more than the outer of elastic claw 221
The taper of male cone (strobilus masculinus) residing for circumferential surface, in this way, when compression ring 22 is moved forward along inner conical surface 211, elastic claw 221 receives radial direction
Compressing force shrink, the chucking power of shape paired cable, mode cable is axially moveable, and compression ring 22 can also use split type knot
Structure, i.e., each elastic claw are separated from each other.The inside of elastic claw 221 is equipped with annular protrusion 222, for increasing clamping of the elastic claw to cable
Power, the annular protrusion can also be hemispherical protuberances.Inner conical surface 211 is to provide certain guiding into fashionable in compression ring 22
Effect, and for increasing the contact area of the inner wall and compression ring 22 of sleeve 21, certainly, inner conical surface 211 can also be
It is that other peripheral surfaces with compression ring 22 such as cylindrical surface or arcwall face coordinate so that can be by when compression ring 22 moves forward
The throat structure of radial compression force；The peripheral surface of elastic claw 221 can also be located on the circumferential surface, at this time by inner conical surface 211 to bullet
Pawl 221 applies radial pressure；The taper of the conical surface of inner conical surface 211 is more than the cone of the male cone (strobilus masculinus) residing for the peripheral surface of elastic claw 221
Degree, can reduce the clamping stroke of compression ring 22 in this way, and the two taper can be with equal certainly.22 rear end of compression ring is equipped with land
223,223 outer diameter of land and the inner wall guiding of sleeve 21 are slidably matched.
Sealing ring 24 is located between extrusion ring 25 and top pressure ring 23, and sealing ring 24 uses rubber material, extrusion ring 25 and top
Pressure ring 23 all uses hard material, and top pressure ring 23 constitutes the conducting piece between sealing ring 24 and compression ring 22, it is, of course, also possible to not have
There are top pressure ring 23, sealing ring 24 to coordinate with 22 direct top pressure of compression ring, to form squeezing action to sealing ring 24, in this implementation
Extrusion ring 25 and top pressure ring 23 are made of metal material in example.The rear end of extrusion ring 25 is equipped with the extended segment 251 to extend back, prolongs
The wall thickness for stretching section 251 is less than the wall thickness of extrusion ring 25, and rear end face is arcwall face, can reduce nut when nut 26 rotates in this way
The frictional force that 26 pushing tow face is slidably matched with extrusion ring 25 can also not have extended segment 251, nut 26 in other embodiments
Pushing tow face act directly on the rear end face of extrusion ring 25, the pushing tow face of nut 26 is its inner face, and extrusion ring 25 may be used also
To be equipped at intervals with the extrusion of the top pressure face coordinated with 24 top pressure of sealing ring.
As shown in fig. 6, the electric connector accessory is in use, tightening nuts 26, you can be completed at the same time the sealing to cable 16
And clamping, installation process is simplified, the quantity of parts is also accordingly reduced, and makes electric connector accessory simple in structure in this way, cost
Lower.
The specific embodiment of the electric connector of the present invention, electric connector includes electric connector accessory, and the electric connector is attached
Part is identical as the structure of the electric connector accessory in the embodiment of above-mentioned electric connector accessory, repeats no more.
