Then rotate bull stick 4, make the line locking mechanism on the bull stick 4 keep away from the junction of public end 2 and female end 1, rotate second semi-ring 27, let second semi-ring 27 and first semi-ring 26 clip the cable, fix riser 28 through second bolt 29 and nut, after first semi-ring 26 and second semi-ring 27 clip the cable, when the cable receives the axial pulling force along the cable, the pulling force can be passed through rubber pad 30, first semi-ring 26, second semi-ring 27 and bull stick 4 and transmitted fixed plate 3, owing to be equipped with inserted bar 6 and rotation post 9 between two fixed plates 3, so the pulling force is passed on the cable of the other end through two fixed plates 3, thereby avoid the connector to receive great pulling force, lead to public end 2 and female end 1's junction to become flexible or rock, influence the normal use of connector. Rubber pad 30 can increase the bearing area and friction force, so that the tensile force applied to the cable is more easily transferred to first half ring 26 and second half ring 27.
When the cable receives radial pulling force, the rubber pad 30 on the inner sides of the first half ring 26 and the second half ring 27 deforms to protect the cable, damage to the cable is reduced, and the radial pulling force received by the cable is also transferred to the first half ring 26 and the second half ring 27, so that the situation that the junction of the cable and the male end 2 or the female end 1 receives excessive radial pulling force is avoided, the junction of the cable and the male end 2 or the female end 1 is broken, and the service life of the cable and the connector is prolonged.
The fixed plate 3 and the bull stick 4 are located connector and cable outside, and when the connector was stepped on or receive other external force extrusion, the fixed plate 3 can protect the connector, and bull stick 4 can protect the junction of cable and connector, reduces the possibility that cable and connector damaged, increase life.
The bottom of the fixed plate 3 is provided with an abutting plate 24 for contact with redundant ground, so that the male end 2 and the female end 1 are placed on the ground more stably, the fixed plate 3 and the connector can be fixed by a through hole 25 on the abutting plate 24, and the male end 2 and the female end 1 can be fixed on the wall surface and other positions; the male end 2 and the female end 1 are supported by the fixing plate 3 and the abutting plate 24, the male end 2 and the female end 1 are not in contact with the ground, and when water is accumulated on the ground, the possibility that the water enters the joint of the male end 2 and the female end 1 can be reduced.
After the male end 2 and the female end 1 are used for a long time, the shell of the female end 1 is deformed, the shell of the male end 2 cannot be tightly attached to the shell of the female end 1, the threaded rod 13 is rotated, the inclined block 14 moves towards the direction close to the female end 1, the clamping plate 12 moves towards the direction far away from the mounting groove 11, the clamping plate 12 protrudes out of the mounting groove 11 and can be in contact with the shell of the female end 1, so that after the shell of the female end 1 is deformed to a certain extent, the male end 2 can still be tightly attached to the female end 1, and shaking between the male end 2 and the female end 1 is avoided, and the service life is influenced.
During normal use, the threaded rod 13 can be rotated to enable the inclined block 14 to move towards the direction close to the female end 1, the clamping plate 12 is in contact with the shell of the female end 1, the male end 2 and the female end 1 are fixed, the fixing effect of the male end 2 and the female end 1 is further improved, and the male end 2 and the female end 1 are prevented from falling off.
After the contact pin 5 is used for a long time, the condition that the contact pin 5 can not be tightly attached to the inner wall of the jack possibly appears, the corresponding first bolt 18 can be screwed at this time, the first bolt 18 moves upwards or downwards after rotating, thereby driving the insulating column 19 and the limiting frame 21 to move up and down, the limiting frame 21 drives the rotating shaft 17 to rotate through the fixing rod 20, thereby adjusting the angle of the contact pin 5, enabling the contact pin 5 to be tightly attached to the inner wall of the jack, avoiding the condition that the contact pin 5 can not be tightly contacted with the inner wall of the jack after long time use, and the signal transmission is unstable, and adjusts aiming at each contact pin 5, the pertinence is stronger, and the adjusting effect is better.
When partial contact pins 5 are damaged, the corresponding contact pins 5 can be rotated, the corresponding contact pins 5 are taken down from the rotating shaft 17, then new contact pins 5 are installed on the rotating shaft 17 through threads, the damaged contact pins 5 can be replaced, the situation that when one contact pin 5 is damaged, the whole connector needs to be replaced is avoided, and the cost is saved.
The foregoing is only a preferred embodiment of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art, who is within the scope of the present application, should make equivalent substitutions or modifications according to the technical scheme of the present application and the inventive concept thereof, and should be covered by the scope of the present application.
