[0008] As a further improvement of the present invention, the operating rod is a hook structure with an angle between the operating end and the driving end. When the driving end of the operating rod rotates forward to drive the follower to rotate so that the elastic clamping structure is in an open position, the direction of the reverse pressure applied by the opening contact surface on the follower to the driving end of the operating rod is perpendicular to the contact position of the driving end of the operating rod and the opening contact surface of the follower, and the direction of the torque generated by the reverse pressure applied by the follower to the driving end on the operating rod shaft is opposite to the direction of the torque generated by the forward rotation stop plane on the operating rod in the opposite direction of the forward rotation limit plane.

[0027] Embodiment: A connector with an operating rod comprises an insulating shell 1, a spring sheet 3 and a conductor 2, wherein a conductor accommodating cavity is formed in the insulating shell 1, the conductor 2 is fixedly installed in the conductor accommodating cavity, the fixed end of the spring sheet 3 is fixed in the conductor accommodating cavity, the elastically deformable clamping end of the spring sheet 3 and the conductor 2 together form an elastic clamping structure for clamping the wire entering the conductor accommodating cavity, and an operating rod 5 and a follower 4 are also provided, the follower 4 is rotatably installed inside the conductor accommodating cavity, a driving block 41 is eccentrically provided on the follower 4, the driving block 41 on the follower 4 can move the clamping end of the spring sheet 3 to elastically deform away from the conductor 2 as the follower 4 rotates, thereby opening the elastic clamping structure, the operating rod 5 is movably installed on the insulating shell 1, the reciprocating motion of the operating rod 5 can drive the follower 4 to rotate forward and reverse within a set angle range, and the operating rod 5 can remain fixed in the position where the elastic clamping structure is opened.

[0028] The conductor 2 and the spring sheet 3 are positioned in the conductor accommodating cavity of the insulating housing 1, and a conducting circuit is formed by clamping the wire 6. When there is no wire in the connector, the initial position of the clamping end on the spring sheet 3 is in close contact with the clamping surface of the conductor 2. When there is a wire in the connector, the initial position of the clamping end on the spring sheet 3 is to clamp the wire between the conductor 2 together with the conductor.

[0029] When it is necessary to disassemble or assemble the wire, first give the operating rod 5 a thrust F1 to make it move to the specified position on the insulating housing 1, and the operating rod 5 will drive the follower 4 to rotate. When the follower 4 rotates, the driving block 41 thereon will rotate synchronously and at the same time drive the clamping end of the spring sheet 3 to elastically deform away from the conductor 2. After the clamping end of the spring sheet 3 is elastically deformed, the gap between the clamping surface of the conductor 2 increases. When the operating rod 5 moves to the specified position on the insulating housing 1, stop applying external force to the operating rod 5, and the operating rod 5 automatically reaches a force balance state. The operating rod 5 remains fixed and the follower 4 also remains in this position. At this time, the driving block 41 on the follower 4 just moves the clamping end of the spring sheet 3 to the state where the elastic clamping structure is opened (the position where the wire is completely loosened or just forms a gap between the conductor 2 for the wire to be freely opened). When the wire is disassembled and assembled, a reverse pressing force F2 is applied to the operating rod 5 to reset it in the reverse direction. As the operating rod 5 is reset, the follower 4 is automatically reset by the elastic force F4 of the clamping end of the spring sheet 3. Finally, the clamping end of the spring sheet 3 is reset to the initial position. When the clamping end of the spring sheet 3 is moved to the open state of the elastic clamping structure, the connector of this structure does not need to hold the operating rod 5 by hand. At this time, the operating rod 5 can be released to insert or pull out the wire. That is, the connector can be operated with one hand during the wire disassembly and assembly process, without the need for both hands to operate at the same time, which is convenient for rapid disassembly and assembly of the wire during construction. No hardware tools are required during the wire disassembly and assembly process, which is easy to operate and improves the work efficiency and operation convenience of the workers.

[0030] The distance L2 between the force point where the follower 4 contacts the operating rod 5 and the axis of the follower 4 is greater than the distance L1 between the force point where the driving protrusion contacts the clamping end of the spring sheet 3 and the axis of the follower 4. In this way, the force applied by the operating rod 5 to the follower 4 is smaller than the elastic force applied by the clamping end of the spring sheet 3 to the driving protrusion, thereby achieving a smaller input force and a larger output force, making the operating rod 5 more labor-saving during operation and more conducive to maintaining the stable state of the follower 4 after the elastic clamping structure is opened.

[0031] The operating rod 5 is rotatably installed on the insulating shell 1 in a lever structure. The operating rod 5 is located at one end of its rotating shaft to form an operating end 51, and the operating rod 5 is located at the other end of its rotating shaft to form a driving end 52. An opening contact surface 42 is formed on the follower 4. The driving end 52 of the operating rod 5 can be rotated in the positive direction to tightly abut the opening contact surface 42 on the follower 4, so that the follower 4 overcomes the elastic force of the clamping end of the spring sheet 3 and rotates. A positive rotation stop plane 11 is provided on the insulating shell 1, and a positive rotation limiting plane 53 is provided on the operating rod 5. When the positive rotation limiting plane 53 of the operating rod 5 is in flat contact with the positive rotation stop plane 11 on the insulating shell 1, the driving end 52 of the operating rod 5 just drives the follower 4 to rotate to a position where the clamping end of the spring sheet 3 opens the elastic clamping structure.

[0032] When the operating rod 5 is rotated to the open position of the elastic clamping structure formed by the spring sheet 3 and the conductor 2, the forward rotation limiting plane 53 on the operating rod 5 is blocked by the forward rotation stop plane 11 on the insulating shell 1, so that the operating rod 5 cannot continue to rotate forward. At this time, the operating rod 5 is stopped and positioned to remain stationary, and the follower 4 will not continue to rotate and remain in a stopped state. Then, the elastic clamping structure formed by the spring sheet 3 and the conductor 2 remains in an open state, which is convenient for wiring and disconnecting. By limiting the forward rotation limiting plane 53 and the forward rotation stop plane 11, the operating rod 5 can be effectively prevented from rotating forward at an excessive angle, and it can be ensured that it is rotated to the open position of the elastic clamping structure and does not move. In addition to adopting a rotating lever structure, the operating rod 5 can also adopt a linear sliding structure, which drives the follower 4 to rotate by sliding, or the operating rod 5 can be designed as a knob rotatably installed on the insulating housing 1, which drives the follower 4 to rotate by being coaxially connected with the follower 4, etc. These are equivalent replacements that can be easily thought of by technical personnel in this field based on the present application, and also fall within the scope of protection of the present application.

[0033] The operating rod 5 is a hook structure with an angle between the operating end 51 and the driving end 52. When the driving end 52 of the operating rod 5 rotates in the positive direction to drive the follower 4 to rotate so that the elastic clamping structure is in the open position, the direction of the reverse pressure applied by the opening contact surface 42 on the follower 4 to the driving end 52 of the operating rod 5 is perpendicular to the contact position between the driving end 52 of the operating rod 5 and the opening contact surface 42 of the follower 4, and the direction of the torque generated by the reverse pressure applied by the follower 4 to the driving end 52 on the operating rod shaft 144 is opposite to the direction of the torque generated by the forward rotation stop plane 11 on the reverse direction of the forward rotation limit plane 53 of the operating rod 5 on the operating rod shaft 144.

[0034] When the operating rod 5 rotates until the positive rotation limit plane 53 is in contact with the positive rotation stop plane 11, the torque generated by the reverse pressure F3 of the driving end 52 of the operating rod 5 from the open contact surface 42 on the follower 4 on the operating rod shaft 144 is just balanced with the reverse pressure torque of the positive rotation stop plane 11 on the positive rotation limit plane 53, so that the operating rod 5 remains fixed in this position. At the same time, the connecting line of the operating rod shaft 144 and the rotating shaft of the follower 4, the connecting line of the contact points between the operating rod shaft 144 and the driving end 52 on the operating rod 5 and the open contact surface 42 on the follower 4, and the connecting line of the contact points between the rotating shaft of the follower 4 and the driving end 52 on the operating rod 5 and the open contact surface 42 on the follower 4 are formed. A stable triangular structure is formed. Under the elastic force of the clamping end of the spring sheet 3, the operating rod 5 and the follower 4 can be stably maintained in this state. In order to reduce the rotation range of the operating rod 5, the operating end 51 and the driving end 52 of the operating rod 5 are designed to be an acute angle. When the structure is used, only the operating end 51 of the operating rod 5 needs to be gently pushed or pressed to drive the follower 4 to rotate through the driving end 52 of the operating rod 5. When the driving block 41 of the follower 4 drives the clamping end of the spring sheet 3 to fully open the elastic clamping structure, the driving end 52 of the operating rod 5 forms an interlocking structure with the follower 4, so that the operating rod 5 and the follower 4 are both force-balanced and maintained in this stable state. In addition to using the above-mentioned interlocking structure to stop and position the operating rod 5 at the open position of the elastic clamping structure, a buckle that can be snapped and connected can be set on the insulating shell and the operating rod 5 for snapping and positioning. Such equivalent replacements are easily thought of by those skilled in the art based on this application and also belong to the protection scope of this application.

[0035] The driving end 52 of the operating rod 5 contacts the opening contact surface 42 on the follower 4 through the first arc surface 521. When the driving end 52 of the operating rod 5 rotates in the positive direction to drive the follower 4 to rotate so that the elastic clamping structure is in the open position, the opening contact surface 42 on the follower 4 is tangent to the first arc surface 521 of the driving end 52 of the operating rod 5. The driving end 52 of the operating rod 5 contacts the opening contact surface 42 on the follower 4 through the first arc surface 521, which can ensure that the operating rod 5 rotates smoothly and prevents jamming. When the opening contact surface 42 on the follower 4 is tangent to the first arc surface 521 of the driving end 52 of the operating rod 5, the follower 4 and the operating rod 5 are both balanced in force to reach an interlocking state.

[0036] The insulating shell is also provided with a reverse rotation stop plane 12, and the operating rod 5 is also provided with a reverse rotation limiting plane 54. When the reverse rotation limiting plane 54 of the operating rod 5 is in flat contact with the reverse rotation stop plane 12 on the insulating shell 1, the driving end 52 of the operating rod 5 is completely separated from the opening contact surface 42 on the follower 4. The follower 4 is also provided with an arc convex package 43, and an arc concave surface 55 is formed on the side wall of the operating rod 5. When the reverse rotation limiting plane 54 of the operating rod 5 is in contact with the reverse rotation stop plane 12 of the insulating shell 1, the arc concave surface 55 on the side wall of the operating rod 5 is in close contact with the arc convex package 43 on the follower 4 in a tangential state. This structure allows the operating rod 5 to rotate in the opposite direction until its driving end 52 is completely disengaged from the opening contact surface 42 on the follower 4. At this time, the follower 4 loses the toggling effect on the clamping end of the spring sheet 3, and the clamping end of the spring sheet 3 is reset. At the same time, the arc concave surface 55 on the operating rod 5 is in close contact with the arc convex bump 43 on the follower 4 to achieve dual positioning of the operating rod 5 and the follower 4, that is, the two form an interlocking structure at this time. At this time, if the operating rod 5 is not subjected to a certain degree of external force, the operating rod 5 and the follower 4 cannot rotate, ensuring that the operating rod 5 and the follower 4 are both stable in the initial state and unchanged, avoiding the phenomenon that the operating rod 5 and the follower 4 rotate randomly, causing the wire clamping failure or the failure to insert the wire normally.

[0037] The operating end 51 of the operating rod 5 is located outside the insulating housing 1. The operating end 51 of the operating rod 5 is provided with pressing contact parts 511 with concave-convex patterns on both sides of the operating end 51 of the operating rod 5 along the rotation direction thereof. The distance L4 from the operating end 51 of the operating rod 5 to its rotation axis is greater than the distance L3 from the driving end 52 of the operating rod 5 to its rotation axis. The operating rod 5 itself forms a lever structure. The length of the operating end 51 is designed to be much greater than the length of the driving end 52, so that the operating end 51 of the operating rod 5 can input less force and achieve a more labor-saving effect. The concave-convex pattern is provided on the operating end, which can play an anti-slip effect and facilitate workers to operate quickly.

[0038] The insulating housing 1 includes an insulating body 14 and an insulating cover 13. The insulating body 14 is formed with a conductor accommodating groove 141. The insulating cover 13 can be fixedly connected to the insulating body 14, and the insulating cover 13 covers the conductor accommodating groove 141 and the opening of the limiting groove of the operating rod 5 to form a conductor accommodating cavity together with the insulating body 14. The insulating body 14 is respectively provided with a first arc-shaped protrusion 143 and an operating rod shaft 144. The insulating cover 13 is provided with a second arc-shaped protrusion 131 and an operating rod shaft positioning hole 132. The inner side wall of the conductor accommodating groove 141, the first arc-shaped protrusion 143, the second arc-shaped protrusion 131 and the insulating cover 13 together form a sleeve structure for the shaft 44 of the follower 4 to be rotatably inserted, and the operating rod shaft 144 can be inserted into the operating rod shaft positioning hole 132 for positioning. The insulating housing 1 is assembled with a split structure, which is convenient for manufacturing and molding.

[0039] The follower 4 is also provided with a closing contact surface 45, which is arranged at intervals with the opening contact surface 42 along the rotation direction of the follower 4. The driving end 52 of the operating rod 5 can be rotated in the reverse direction to abut against the closing contact surface 45 on the follower 4, thereby driving the follower 4 to rotate and release the clamping end of the spring sheet 3. When the operating rod 5 rotates in the reverse direction, the follower 4 is driven to rotate by pushing the closing contact surface 45 on the follower 4, thereby preventing the follower 4 from not being reset in time when the operating rod 5 rotates in the reverse direction.

[0040] The clamping end of the spring sheet 3 is an elastic cantilever structure, and the driving block 41 on the follower 4 is in close contact with the side wall of the clamping end of the spring sheet 3 through the second arc surface 411, thereby elastically deforming the clamping end of the spring sheet 3. The driving block 41 is in contact with the clamping end of the spring sheet 3 through the second arc surface 411 to prevent the occurrence of jamming and ensure smooth rotation of the follower 4.
