Detailed Description

The invention will be further described with reference to the following description and embodiments in conjunction with the accompanying drawings:

as shown in fig. 1 to 3, an anti-pulling connector comprises a connector body 1 having a male end or a female end, a housing of the connector body 1 is composed of an end 10 and a cylinder 11, a bottom plate 12 is disposed at a rear end of the cylinder 11, a moving ring 2 is movably disposed on the cylinder 11, a tension spring 13 is disposed between the moving ring 2 and the bottom plate 12, hinge blocks 20 are symmetrically disposed on an outer circumferential wall of the moving ring 2, a clamping plate 3 is hinged to the hinge blocks 20 for clamping another connector connected to the connector body 1, a torsion spring is disposed at a hinge position between the hinge blocks 20 and the clamping plate 3 for closing the two clamping plates 3, after the connector body 1 is connected to another connector, an end of another connector connected to the connector body 1 is clamped by the torsion spring and the clamping plate 3, thereby effectively preventing pulling due to an external force, the two connectors are separated to damage the joints of the connectors or break the electric wires, and the tension spring 13 enables the clamping plate 3 to clamp the end of the other connector and simultaneously pulls the other connector to move towards the connector body 1, so that the two connectors are connected more firmly.

The outer end of the clamping plate 3 is provided with a clamping head 30 for clamping the end of another connector connected with the connector body 1.

Be equipped with rubber antiskid line 31 on chuck 30's the tight face of clamp, can increase frictional force through being equipped with rubber antiskid line 31, prevent to break away from chuck 30 by the connector of 3 centre grippings of pinch plate.

The utility model is provided with a conical ring body 14 outside the column body 11 on the bottom plate 12, the outer diameter of the conical ring body 14 is gradually enlarged from back to front, the moving ring 2 is movably arranged between the conical ring body 14 and the column body 11, the bottom surface of the clamping plate 3 can be tightly attached to the outer side surface of the conical ring body 14, avoidance grooves 15 are symmetrically arranged on the conical ring body 14, the hinge block 20 is arranged in the avoidance grooves 15, when in use, after the connector body 1 is connected with another connector, the clamping plate 3 is gradually turned outwards along the outer surface of the conical ring body 14 by pushing the clamping plate 3 forwards, thereby expanding the clamping heads 30 on the clamping plate 3, when the clamping plate 3 moves out of the conical ring body 14, the torsion spring makes the clamping plate 3 turn inwards to play a role of clamping, thereby allowing the collet 30 to grip the end of the other connector and act to prevent damage to the internal components of the connector or the wire from being pulled apart by pulling.

The utility model discloses be equipped with guide ring 4 on the front end of bottom plate 12 be equipped with convex lug 32 on the articulated department rear end of clamp plate 3 be equipped with on the preceding terminal surface of guide ring 4 with the oblique guide surface 40 that convex lug was prepared mutually, it is used for with convex lug is along the upset of oblique guide surface 40, makes clamp plate 3 outwards open, when needs clamp plate 3 to return back, through rotating 90 degrees with shift ring 2 to outwards overturn clamp plate 3, thereby make shift ring 2 reset through extension spring 13, when convex lug contacted oblique guide surface 40, along the upset of oblique guide surface 40, thereby realize clamp plate 3 and outwards open, turn around 90 degrees shift ring 2 this moment, make clamp plate 3 paste tightly again in on the toper ring body 14, wait for the next connection of connector.
