Description

Technical Field

[0001] This invention relates to the field of connection device technology, and more particularly to a push-pull network connector. Background Technology

[0002] With the rapid development of the Industrial Internet, the reliability of the physical connection of the Industrial Internet gateway, as a key node connecting field devices and cloud systems, directly affects the stability of the entire data acquisition and monitoring system. Meanwhile, in the manufacturing of new electrical contact precious metal materials, although the gold and nickel composite plating prepared by advanced processes such as magnetron sputtering can significantly improve the wear resistance and conductivity of the contacts, its excellent electrical contact performance still depends on the effective isolation of external mechanical stress by the connector structure itself. Push-pull network connectors are widely used in network communication, industrial control, medical equipment, aerospace and other fields due to their convenient operation and reliable connection. Traditional push-pull self-locking connectors usually adopt a structure that automatically locks after the plug and socket are inserted, such as through an elastic buckle structure to achieve self-locking. When the user needs to separate the connector, he / she unlocks the elastic buckle and pulls the plug shell backward to disengage the locking structure, thereby unlocking.

[0003] In practical use, especially in situations with complex cable layouts, existing push-pull network connectors are prone to accidental dragging of the cable connected to the plug assembly. When the external force acts directly on the cable, the pulling force is directly transmitted to the locking mechanism inside the plug. For existing push-pull self-locking connectors, if the force of the accidental pull is too great, it is very easy to cause the locking mechanism to malfunction, causing the plug assembly to be accidentally pulled out of the socket, i.e., accidental pull-out or accidental unlocking. This will not only cause signal transmission interruption, but may also damage the device interface or ongoing business processes, causing inconvenience or even losses to users.

[0025] Reference Figures 1-9 In a preferred embodiment, a passive protection module 7 is provided on one side of the support rod 603, and the passive protection module 7 includes a detection frame 702. A displacement column 701 is fixedly connected to one side of each of the two sliders 604. The detection frame 702 is provided on one side of the support rod 603, and a vision sensor 703 is provided on one side of each of the two detection frames 702.

[0026] Specifically, when connector 2 is inserted into connector 4, the elastic element 5 in connector 2 is inserted into the insertion slot on connector 4. At the same time, the locking hook 611 in tensile module 6, under the action of pre-tightening spring 614, maintains a certain pre-tightening force, causing it to engage in the locking slots at the ends of locking cylinders 617 on both sides of connector 4, achieving initial electrical connection and physical fixation. At this time, slider 604 is located at the initial position of slide groove of support rod 603 under the action of telescopic spring 605, and the entire system is in standby state. When the connecting cable is dragged by an unexpected external force, the tension first acts on metal telescopic protective sleeve 601 and telescopic cable head 602. Metal telescopic protective sleeve 601 has a certain degree of elasticity. It can absorb part of the initial impact force. As the tension increases, the metal telescopic protective sleeve 601 is stretched, causing the support sleeve plate 607 at its end to move in the dragging direction. The support sleeve plate 607 pulls the slider 604 to slide in the groove of the support rod 603 through the linkage cylinder 606, and at the same time compresses the telescopic spring 605. The movement of the slider 604 causes the L-connecting frame 608 and the locking hook 611 installed on it to move synchronously. Since the locking hook 611 was originally stuck in the groove of the locking cylinder 617, when the locking hook 611 moves with the slider 604, it will pull the entire anti-tension slide 616 along the guide rod 618 through the locking cylinder 617 and compress the return spring 619. The process converts the external linear drag force into a force that drives the internal anti-tension slide 616 to move. The locking hook 611, originally used to prevent loosening, now becomes a transmission component that transmits the pulling force, causing the entire locking mechanism to move backward instead of unlocking directly. While the anti-tension slide 616 moves backward, the displacement sensor 625 monitors the displacement of the anti-tension slide 616 in real time, i.e., the extent to which the cable is dragged. When the displacement sensor 625 detects that the displacement exceeds the preset safety threshold, the controller 609 determines that it is in a "pulling state". The controller 609 activates the electric telescopic cylinder 624, pushing the adjusting slide plate 622 to slide within the limit track 621, causing the rubber extrusion protrusion 623 to move inward. The rubber extrusion protrusion 623 first squeezes the contact roller 631, pushing the horizontal moving column 627 to move towards the connecting seat 4 against the force of the second telescopic spring 628. This causes the stop roller 630 to press tightly against the rubber corrugated plate 626 on the side of the connecting seat 4, greatly increasing the friction. At the same time, due to the continuous extrusion of the rubber extrusion protrusion 623, the movement of the entire tooling frame 620 and the anti-tension slide 616 is subject to stronger resistance, which is equivalent to providing an additional braking force for the already backward anti-tension slide 616 to prevent it from continuing to move backward and causing it to disengage. When the external force disappears, under the elastic force of the first telescopic spring 605 and the return spring 619, the slider 604 and the anti-tension slide 616 begin to return to their original positions. In specific application scenarios, when tension is applied to the cable, the metal telescopic protective sleeve 601 first absorbs part of the initial impact energy through its own telescopic characteristics, preventing the instantaneous rigid tension from being directly transmitted to the fragile circuit inside the connector 2. The tension is then transmitted to the telescopic spring 605 through the linkage cylinder 606, converting the sudden mechanical energy into the elastic potential energy of the spring. This process prolongs the action time of the originally instantaneous tension, greatly reducing the impact damage. In traditional connectors, the locking hook 611 only serves as a "lock" to prevent loosening. In this module, when tension is generated, the locking hook 611 not only does not loosen, but also acts as a transmission component, transmitting the tension to the locking cylinder 617, thereby pulling the entire anti-tension slide 616 backward, changing the connection between the connector 2 and the connector 4 from rigid fixed to elastic follow-up. The entire locking mechanism moves backward as a whole when pulled, instead of separating at the interface, fundamentally eliminating the phenomenon of accidental pull-out caused by slight or moderate pulling. The displacement sensor 625 monitors the displacement of the anti-tension slide 616 in real time, realizing precise quantification of the pulling force. When the displacement exceeds the safety threshold, the electric telescopic cylinder 624 pushes the rubber extrusion protrusion 623, which in turn makes the stop roller 630 press tightly against the rubber corrugated plate 626. This action generates huge frictional resistance, which is equivalent to applying a mechanical brake to the retracting anti-tension slide 616, effectively preventing it from continuing to move backward under pulling until it is disengaged. When the external force disappears, the slider 604 and the anti-tension slide 616 can automatically reset by relying on the elastic force of the telescopic spring 605 and the return spring 619, so that the connector returns to the normal locking state and can continue to be used without manual intervention.

[0027] Reference Figure 3 , Figure 5 and Figure 7 In a preferred embodiment, two support plates 705 are fixedly connected to one side of each of the two L-connecting frames 608, and one side of each of the support plates 705 is provided with a circular hole 3. The interior of each of the two opposing circular holes 3 is connected to the same rotating shaft 706 through a bearing. The exterior of each of the two rotating shafts 706 is fixedly connected with an unlocking claw arm 707, which is located on one side of the locking hook 611. An adjusting motor 708 is provided on one side of each of the two support plates 705, and the drive end of the adjusting motor 708 is connected to one end of the rotating shaft 706 through a coupling.

[0028] Reference Figure 3 , Figure 5 , Figure 7 and Figure 10In a preferred embodiment, the two locking cylinders 617 are externally fixedly connected to the same U-shaped support rod 704, and two through holes are opened on one side of the U-shaped support rod 704. The two through holes are slidably connected to the inside of the two through holes. The same compression spring 710 is fixedly connected to the opposite side of the compression column 709 and the U-shaped support rod 704. The compression spring 710 is located outside the compression column 709.

[0029] Reference Figure 1 and Figure 10 In a preferred embodiment, one end of each of the two extrusion columns 709 is fixedly connected to the same lifting fixture frame 711, and both sides of the lifting fixture frame 711 are provided with round holes four. The interior of the two round holes four is connected to the same unlocking lower pressure roller 712 through bearings, and the unlocking lower pressure roller 712 slides on one side of the connecting seat 4.

[0030] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, an elastic element 5 is provided on one side of the connector 2, and a flexible press-to-unlock button 3 is provided on one side of the connector 2. The flexible press-to-unlock button 3 is located above the elastic element 5, and an insertion slot is provided on one side of the connector 4.

[0031] Specifically, when the external force of drag is large, the slider 604 continues to slide to the limit position on the slide groove of the support rod 603. At this time, the passive protection module 7 installed on the L tooling frame 620 starts to work. When the slider 604 moves, it will drive the displacement column 701 to move. When the vision sensor 703 on the detection frame 702 detects the displacement column 701, the controller 609 adjusts the motor 708 to start, driving the rotating shaft 706 to rotate, causing the unlocking claw arm 707 to swing upward. The unlocking claw arm 707 pushes up the locking hook 611, causing it to rotate around the rotating shaft 610, thereby disengaging from the locking groove of the locking cylinder 617 and completing the unlocking. In addition, the floating unlocking mechanism composed of the extrusion column 709, extrusion spring 710 and unlocking lower pressure roller 712 on the U-shaped support rod 704, through the unlocking lower pressure roller 712 pressing the elastic element 5 to make it fall off, ensures that the connector can be quickly disengaged when subjected to strong pulling, forming protection. In specific application scenarios, when the pulling force is extremely high, causing the slider 604 to continue sliding to its limit position on the groove of the support rod 603, the displacement column 701 enters the field of view of the detection frame 702. The intervention of the vision sensor 703 provides redundant monitoring in addition to the displacement sensor 625, ensuring the accuracy and reliability of triggering under extreme working conditions. After receiving the visual signal, the controller 609 determines that the external force at this time has exceeded the normal buffer range, and continued resistance may cause damage to the main body 1 or the connecting seat 4. Therefore, it decisively executes the forced disengagement command, adjusting the motor 708 to drive the unlocking claw arm 707 to swing upward and actively lift the locking hook 6. 11. Forcefully disengage it from the locking groove of the locking cylinder 617. This step is an active release of the locking relationship, rather than being passively pulled out. Rather than letting uncontrollable forceful pulling damage the expensive main body of the equipment 1, it is better to let the connector actively disconnect under controlled conditions. At the same time, the U-shaped support rod 704, the compression column 709, the compression spring 710 and the unlocking lower pressure roller 712 constitute a floating auxiliary disengagement mechanism. When the locking hook 611 is disengaged, the unlocking lower pressure roller 712, under the action of the compression spring 710, presses the elastic element 5 and applies an outward pushing force to help the connector 2 quickly and smoothly pop out of the insertion groove of the connector 4.

[0032] Working principle: When connector 2 is inserted into connector 4, the elastic element 5 in connector 2 inserts into the insertion groove on connector 4. At the same time, the locking hook 611 in tensile module 6, under the action of pre-tightening spring 614, maintains a certain pre-tightening force, causing it to engage in the locking grooves at the ends of locking cylinders 617 on both sides of connector 4, achieving initial electrical connection and physical fixation. At this time, slider 604 is located in the initial position of slide groove of support rod 603 under the action of telescopic spring 605, and the entire system is in standby state. When the connecting cable is dragged by an unexpected external force, the tension first acts on metal telescopic protective sleeve 601 and telescopic cable head 602. Metal telescopic protective sleeve 601 has a certain degree of elasticity and can absorb part of the initial impact force. As the tension increases, The metal telescopic protective sleeve 601 is stretched, causing the support sleeve plate 607 at its end to move in the dragging direction. The support sleeve plate 607 pulls the slider 604 through the linkage cylinder 606 to slide in the groove of the support rod 603, while compressing the telescopic spring 605. The movement of the slider 604 causes the L-connecting frame 608 and the locking hook 611 installed on it to move synchronously. Since the locking hook 611 was originally stuck in the groove of the locking cylinder 617, when the locking hook 611 moves with the slider 604, it will pull the entire anti-tension slide 616 along the guide rod 618 through the locking cylinder 617 and compress the return spring 619. This process converts the external linear drag force into the force that drives the internal anti-tension slide 616 to move, which was originally used to prevent loosening. At this moment, the locking hook 611 becomes a transmission component for transmitting tension, causing the entire locking mechanism to move backward instead of unlocking directly. While the anti-tension slide 616 moves backward, the displacement sensor 625 monitors the displacement of the anti-tension slide 616 in real time, i.e., the extent to which the cable is dragged. When the displacement sensor 625 detects that the displacement exceeds a preset safety threshold, the controller 609 determines it to be in a pulling state. The controller 609 activates the electric telescopic cylinder 624, pushing the adjusting slide plate 622 to slide within the limit track 621, causing the rubber extrusion protrusion 623 to move inward. The rubber extrusion protrusion 623 first squeezes the abutment roller 631, pushing the horizontal moving column 627 to overcome the force of the telescopic spring 628 and move towards the connecting seat 4, thereby causing the stop roller 63... The rubber corrugated plate 626 on the side of the connecting seat 4 is pressed tightly against the 0, greatly increasing the friction. At the same time, due to the continuous compression of the rubber extrusion protrusion 623, the movement of the entire tooling frame 620 and the tensile slide 616 is subject to stronger resistance, which is equivalent to providing an additional braking force for the already backward-moving tensile slide 616 to prevent it from continuing to move backward and causing it to disengage. When the external force disappears, under the elastic force of the telescopic spring 605 and the return spring 619, the slider 604 and the tensile slide 616 begin to return to their original positions. When the dragging external force is large, the slider 604 continues to slide on the slide groove of the support rod 603 to the limit position. At this time, the passive protection module 7 installed on the L tooling frame 620 starts to work. When the slider 604 moves, it will drive the displacement column 701 to move.When the vision sensor 703 on the detection frame 702 detects the displacement post 701, the controller 609 starts the motor 708, driving the rotating shaft 706 to rotate. This causes the unlocking claw arm 707 to swing upward, lifting the locking hook 611 and causing it to rotate around the rotating shaft 610, thus disengaging it from the locking groove of the locking cylinder 617 and completing the unlocking process. Furthermore, the floating unlocking mechanism, consisting of the compression post 709 on the U-shaped support rod 704, the compression spring 710, and the unlocking lower pressure roller 712, ensures that the connector quickly disengages under strong pulling, providing protection.
