Description

Technical Field

[0001] This invention relates to the field of electrical connector technology, and more particularly to an electrical connector with quick-locking and its operating method. Background Technology

[0002] Electrical connectors (or plug-in connectors) are basic electromechanical components that achieve circuit connection by mechanically mating and separating a plug and a socket. Electrically, connectors require low and stable contact resistance, high insulation resistance, and sufficient withstand voltage. Mechanically, they need appropriate mating and extraction forces and a specified mating and extraction life, and must be able to withstand operating environments such as temperature, humidity, vibration, and salt spray.

[0003] Chinese patent document (publication number: CN122000735B) discloses an aviation electrical connector assembly, including a male connector and a female connector. A mounting base is fixedly connected to the end of the male connector. Several arc-shaped locking blocks are slidably connected in a ring array at the bottom of the mounting base. A first spring is fixedly connected between the arc-shaped locking blocks and the mounting base. An annular groove is formed on the inner wall of the female connector corresponding to the position of the arc-shaped locking blocks. This invention, by setting up the arc-shaped locking blocks, the first spring, and the annular groove, allows for simple and effortless connection. During connection, pressing a button retracts the arc-shaped locking blocks, and releasing the button after insertion causes the blocks to automatically engage with the groove and lock. During separation, pressing the button again retracts the blocks, allowing them to disengage from the groove. The entire operation is simple and effortless, saving time and energy.

[0004] When existing plugs are connected, the plug rod and the elastic electrode contact piece are in direct contact and slide relative to each other under the power-on state until they are in place and static conduction is formed. During this energized sliding process, the contact pressure between the contact piece and the plug rod changes dynamically with the insertion depth, and the contact resistance will fluctuate. This may cause local high temperature and induce micro-arcs or arcing, burn the conductive layer of the contact piece, generate an insulating film, increase the contact resistance, aggravate heat generation and insulation aging, and in severe cases, cause welding or fire. At the same time, sliding friction causes mechanical scraping and abrasive wear. After repeated insertion and removal, the contact piece deforms and its elasticity decreases, which may lead to poor contact or failure. Moreover, after the plug is in place, it is usually fixed by screwing on a spiral structure, which is inefficient and inconvenient to operate. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an electrical connector with quick locking and its operating method. The timing of energizing the electrode contacts is linked to the mechanical limiting process of the plug rod. As the plug rod extends into the socket, it first completes the engagement and limiting of the lifting opening and locking groove. Then, the first and second protrusions push the electrode pieces to contact the electrode contact plate to achieve energization. This avoids the contact resistance fluctuations and local overheating problems caused by the energized sliding contact of traditional plugs.

[0008] Furthermore, protruding rods are fixedly installed on the bottom of both sides of the guide plate, and limiting grooves are opened on both sides of the guide groove. The protruding rods are slidably installed in the limiting grooves. In-situ springs are installed in the limiting grooves.

[0010] Furthermore, the locking assembly includes a pressure plate and a locking plate. Slide grooves are symmetrically formed on the inner wall of the through groove. The slide grooves and the second rotating rod are distributed at both ends along the thickness direction of the guide plate, with the slide grooves located at the end furthest from the rotating plate. The pressure plate is slidably installed inside the slide groove, with its bottom end abutting against the top end of the flip plate. A guide rod is slidably inserted through the top of the pressure plate, and its top end is fixedly connected to the inner top wall of the through groove. A return spring is slidably sleeved on the guide rod, with its two ends fixedly connected to the pressure plate and the inner top wall of the through groove, respectively. A sliding cavity is provided in the guide plate located at the top of the slide groove, and the sliding cavity is connected to the slide groove. Two spaced locks are rotatably installed inside the sliding cavity via a pin. A plate is formed by connecting two locking plates with a tension spring. The tension spring keeps the ends of the locking plates at the top of the slide groove, and the locking plates limit the displacement of the pressure plate in the slide groove. Protrusions are provided on the opposing surfaces between the two locking plates. A guide groove is provided on the bottom plate of the sliding cavity between the two locking plates by a recessed manner. A push rod is slidably installed in the guide groove, and the two sides of the push rod abut against the two protrusions respectively. A return spring is elastically connected between the inner top wall of the guide groove and the push rod. The other end of the push rod slides through the guide plate and extends to its outside. A protruding plate is fixed on the inner upper wall of the guide groove. During the movement of the guide plate, the protruding plate abuts against the push rod, and the moving push rod pushes the two locking plates away from the top of the slide groove.

[0011] Furthermore, the contact voltage engagement mechanism includes an electrode plate, a return spring, and an electrode contact plate; a first protrusion is fixed on one side of the bottom end of the guide plate, and an electrode plate is installed on the outside of one side of the first protrusion.

[0012] Furthermore, the power mechanism includes pressure rods, toothed plates, gears, and return springs; two pressure rods are symmetrically arranged on the same radial plane of the first connector, and the pressure rods slide through the housing of the first connector and extend to the outside; the end of the rotating shaft is rotatably mounted on the inner wall of the first connector, and a gear is fixed on the rotating shaft, with the gear located between the two pressure rods; toothed plate frames are respectively arranged at the inner ends of the two pressure rods, and the two toothed plate frames are arranged in an array with the gear as the center; the toothed plate frame includes a horizontal plate fixed to the end of the pressure rod, one end of the horizontal plate is vertically connected to a guide plate, and the other end of the horizontal plate is vertically connected to a toothed plate, the toothed plate meshing with the gear, and the guide plate and the toothed plate sliding in corresponding guide grooves; a guide post slides through the bottom end of the horizontal plate, and the other end of the guide post is fixedly connected to the inner wall of the first connector, with a return spring sleeved on the guide post.

[0013] Furthermore, a pressure cap is fixed to the top of the pressure rod, and a limiting pad is detachably fitted on the pressure rod located between the pressure cap and the outer shell of the first connector. The limiting pad and the pressure cap are fixedly connected by a rope. The limiting pad is a block-shaped structure with a through-center, and one side of the limiting pad extends outward to form a three-sided opening structure. The limiting pad is made of rubber. A buffer groove is formed at the bottom of the electrode contact. A buffer contact is slidably installed inside the buffer groove. The buffer contact is elastically connected to the top wall of the buffer groove by a buffer spring. The buffer contact is electrically connected to the electrode.

[0014] Furthermore, the first connector has a socket including a protective socket and two electrical connection sockets; the second connector has a rod including a protective rod and two electrical connection rods; the two electrical connection rods extend into the two electrical connection sockets respectively to form an electrical connection; the protective rod extends into the protective socket to form a protective electrical connection; the protective rod has an irregular shape; a normally connected protective contact is provided at the opening of the protective socket; an outer edge is provided on the second connector, and a sealing ring is formed on the inner wall of the outer edge; an annular groove is formed on the outer wall of the first connector, and the sealing ring is pressed into the annular groove to form a seal.

[0015] Furthermore, a method for operating the aforementioned electrical connector with quick-locking feature is provided, comprising the following steps: S1. Before docking, the rotating plate is kept in a fixed position under the action of the first torsion spring, the electrode contact is far away from the insertion hole of the first connector and has no contact with the insertion rod of the second connector, and the power supply is in the off state. S2. Insert the plug of the second connector into the socket of the first connector. The inclined surface of the end of the plug pushes the guide plate away from the center groove and moves the flip plate synchronously. The flip plate pushes the rotating plate to rotate around the first rotating rod, causing the buffer contact on the electrode contact to approach and contact the plug. At the same time, the inner top of the lifting port is locked into the locking groove to achieve the limit locking of the plug. S3. During the movement of the guide plate, the first protrusion contacts the second protrusion and pushes the electrode sheet to deflect, so that the electrode sheet contacts the electrode contact plate to form an electrical connection. The electrode contact plate is energized to complete the quick insertion and locking. S4. When disconnecting, after removing the limit pad, drive the two pressure caps to move relative to each other. Drive the gear to rotate through the two toothed plates. Drive the cam to push the guide plate to move away from the center line of the second connector through the rotating shaft. The first ridge separates from the second ridge. The electrode plate separates from the electrode contact plate and the arc is cut off by the arc-extinguishing grid. S5. The guide plate continues to move, causing the push rod to push the locking plate to release the limit on the pressure plate. The rotating plate is reset by the flip plate and the electrode contact is disengaged from the electrical connector rod. The second connector is pulled out to complete the unlocking and separation.

[0016] The beneficial effects of this invention include: 1. In this invention, the timing of energizing the electrode contact and the mechanical limiting process of the plug are linked. This design allows the plug to first engage with the locking groove during insertion into the socket, and then the first and second protrusions push the electrode to contact the electrode contact plate to achieve energization. This avoids the contact resistance fluctuations and local overheating problems caused by the sliding contact of a traditional plug. Simultaneously, during unlocking, the cam drives the guide plate to move, causing the electrode to first separate from the electrode contact plate and de-energize. Then, the push rod releases the limiting of the pressure plate, allowing the rotating plate to reset, achieving de-energization and unlocking. This, combined with the arc-extinguishing grid, divides and suppresses the arc generated at the moment of separation. The mechanical limiting and electrical on / off paths work together to ensure fast insertion and locking efficiency while significantly reducing the risk of contact erosion, insulation aging, and arc burns. This achieves a synergistic effect that is difficult to achieve by relying solely on structural locking or electrical control.

[0017] 2. In this invention, the rotating plate is rotatably installed in the receiving groove by the first rotating rod, and is kept in a fixed posture without external force by two first torsion springs installed in opposite directions, so that the electrode contact is always kept at a distance from the insertion hole; when the insertion rod is inserted, the rotating plate is deflected by the pushing action of the flip plate, so that the electrode contact only contacts the insertion rod after it is in place, thereby reducing the contact pressure fluctuation caused by the electric slippage between the contact and the insertion rod during the insertion and removal process, reducing the electrolytic erosion loss and abrasive wear of the conductive layer of the contact, which is beneficial to extending the service life of the contact and maintaining the stability of the contact.

[0018] 3. In this invention, the protruding rods on both sides of the guide plate, together with the limiting groove and the in-situ spring, form a reciprocating guide structure, which allows the guide plate to slide smoothly along the guide groove under the push of the insertion rod and can automatically reset. The flap plate set at the top of the guide plate cooperates with the eccentrically arranged second rotating rod and second torsion spring to convert the linear displacement of the guide plate into the rotation of the rotating plate. The pressure plate and locking plate in the locking assembly form a staged limit on the rotation state of the flap plate, so that the locking action between the top of the lifting port and the top of the slope surface is synchronized with the contact action of the electrode contact piece, reducing the situation of incomplete contact or mis-locking caused by the malfunction of a single component, and improving the reliability of the insertion process.

[0019] 4. In this invention, the electrode plates in the contact voltage connection mechanism achieve deflection and conduction through the staggered pushing method of the first and second protrusions, and achieve automatic separation and power-off with the help of the reset spring. The arc-extinguishing grid set on one side of the electrode contact plate can divide and weaken the electric arc generated at the moment of separation between the electrode plate and the electrode contact plate. The power mechanism converts the relative squeezing action of the two pressure caps into the rotation of the cam through symmetrically arranged pressure rods, toothed plates and gears, thereby driving the guide plate to move and unlock as a whole. Compared with the traditional spiral screw fixing method, the operation path is more direct. With the detachable protective design of the limit pad and rope, it takes into account the need to prevent accidental contact in daily use and the convenience of operation during maintenance.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0024] Example 1:

[0025] like Figure 1-12 As shown, an electrical connector with quick locking includes a first connector 11 with a socket and a second connector 12 with a plug. The first connector 11 has three sets of guide grooves 22 arranged along the same radial plane inside. The three sets of guide grooves 22 extend outward from the center of the radial plane to the inner edge of the first connector 11. A guide plate 27 is slidably installed inside each guide groove 22. The sockets on the first connector 11 are respectively connected to the corresponding guide grooves 22 from the outside. The three sets of guide grooves 22 extend in a direction parallel to the sockets of the first connector 11 to form receiving grooves 67, which are connected to adjacent sockets. A rotating plate 28 is rotatably installed inside the receiving groove 67. One end of the rotating plate 28 abuts against a pushing mechanism on the guide plate 27, and the other end of the rotating plate 28... The first connector 12 has an electrode contact 29 at one end; the second connector 12 has a ramp 37 at the end of its insertion rod, and three sets of guide plates 27 have lifting openings 30 corresponding to the ramp 37. A locking groove 38 is opened at the top of the ramp 37; a power-on / off contact contact mechanism is provided on one side of the guide plate 27; a central groove 21 is opened at the center of the radial plane where the three sets of guide grooves 22 are located. The central groove 21 is connected to the guide groove 22. A cam 23 is rotatably installed in the central groove 21. The rotating shaft 39 of the cam 23 is connected to the power mechanism; when the insertion rod of the second connector 12 is inserted into the insertion hole of the first connector 11, the insertion rod is not in contact with the electrode contact 29 and the power is disconnected. After the insertion rod is in place, it is electrically connected to the electrode contact 29 and triggers the switching mechanism to connect the power.

[0026] In this invention, the timing of energizing the electrode contact 29 is linked to the mechanical limiting process of the plug rod. This allows the plug rod 15 to first engage and limit the lifting port 30 and locking groove 38 during insertion into the socket. Then, the first protrusion 40 and the second protrusion 42 push the electrode 41 to contact the electrode contact plate 44 to achieve energization. This avoids the contact resistance fluctuations and local overheating problems caused by the energized sliding contact of traditional plugs. At the same time, during unlocking, the cam 23 drives the guide plate 27 to move, causing the electrode 41 to separate from the electrode contact plate 44 and de-energize. Then, the push rod 52 releases the limit on the pressure plate 49, allowing the rotating plate 28 to reset, achieving de-energization and unlocking. The arc-extinguishing grid 68 further divides and suppresses the arc generated at the moment of separation. The mechanical limiting and electrical switching paths work together to ensure fast insertion and locking efficiency while significantly reducing the risk of contact erosion, insulation aging, and arc burns. This achieves a synergistic effect that is difficult to achieve by relying solely on structural locking or solely on electrical control.

[0027] Furthermore, a first rotating rod 35 is rotatably mounted on the rotating plate 28, with both ends of the first rotating rod 35 fixedly installed on the inner wall of the receiving groove 67; a first torsion spring 36 is respectively sleeved on both ends of the first rotating rod 35, with the inner rod of the first torsion spring 36 fixedly connected to the first rotating rod 35 and the outer rod of the first torsion spring 36 fixedly connected to the rotating plate 28; the two first torsion springs 36 are installed in opposite directions to ensure forward and reverse rotation and reset; the two first torsion springs 36 keep the rotating plate 28 in a fixed position when there is no external force, and keep the electrode contact 29 and the insertion hole of the first connector 11 at a distance.

[0028] The two first torsion springs 36, which are sleeved at both ends of the first rotating rod 35, are installed in a reverse rotation manner, so that the rotating plate 28 can rotate smoothly toward the insertion rod when it is pushed by an external force, and can be reset in the opposite direction with the help of the restoring force of the torsion spring after the external force is released, thus taking into account both the smoothness of rotation in both directions and the reliability of reset.

[0029] The elastic force of the two first torsion springs 36 keeps the rotating plate 28 in a fixed position without external force, maintaining a certain distance between the electrode contact 29 and the insertion hole of the first connector 11. Maintaining this distance ensures that the insertion rod does not contact the electrode contact 29 in the initial stage of insertion into the insertion hole, avoiding relative sliding friction between the insertion rod and the electrode contact 29 under energized conditions during insertion. This helps to reduce contact resistance fluctuations caused by dynamic contact pressure changes, and has a positive effect on reducing the probability of local overheating and micro-arc ablation. It also reduces the elastic decay of the contact due to repeated scraping and wear, which is beneficial to maintaining the contact stability of the electrode contact 29 during long-term use.

[0030] Furthermore, protruding rods 32 are fixedly installed on the bottom of both sides of the guide plate 27, and limiting grooves 33 are opened on both side walls of the guide groove 22. The protruding rods 32 are slidably installed in the limiting grooves 33. In-situ springs 34 are respectively installed in the limiting grooves 33. The in-situ springs 34 are located at the end away from the central groove 21, and the two ends of the in-situ springs 34 are fixedly connected to the top of the protruding rods 32 and the inner top wall of the limiting groove 33, respectively. The bottom of the guide plate 27 is located in the central groove 21.

[0031] The in-situ spring 34, located at the end of the limiting groove 33 away from the central groove 21, is fixedly connected at both ends to the top of the protruding rod 32 and the inner top wall of the limiting groove 33. When the guide plate 27 is pushed by the insertion rod and moves towards the central groove 21, it is compressed and accumulates a certain elastic restoring force. When the insertion rod is released, the restoring force of the in-situ spring 34 can drive the protruding rod 32 and the guide plate 27 to return to their original positions along the limiting groove 33, so that the guide plate 27 has the ability to automatically reset, reducing the reliance on additional reset operations, and also helping to maintain the consistency of the position of the guide plate 27 after multiple insertions and removals.

[0032] Furthermore, the pushing mechanism includes a flap 47, in which a second rotating rod 48 is rotatably inserted; a through groove 31 is formed on the top of the guide plate 27 along the thickness direction, and the two ends of the second rotating rod 48 are respectively fixedly installed on the inner wall of the through groove 31, with the second rotating rod 48 being eccentrically positioned and located on the side closer to the flap 28; a second torsion spring 57 is respectively sleeved on both ends of the second rotating rod 48, with the inner rod of the second torsion spring 57 fixedly connected to the second rotating rod 48, and the outer rod of the second torsion spring 57 fixedly attached. Connecting flap 47, two second torsion springs 57 are installed in opposite directions to ensure forward and reverse rotation and reset; the two second torsion springs 57 keep flap 47 perpendicular to the length direction of guide plate 27 when there is no external force; one end of flap 47 extends to the bottom end of rotating plate 28 and overlaps on the projection surface, and the other end of flap 47 extends along the thickness direction of through groove 31 to the edge of through groove 31. A locking assembly is provided on guide plate 27, and the locking assembly and rotating plate 28 are located on the same side of flap 47.

[0033] The second rotating rod 48, which is rotatably inserted in the flap 47, is fixed to the inner wall of the through groove 31 near the rotating plate 28 in an eccentric manner. This eccentric arrangement enables the flap 47 to rotate asymmetrically when subjected to force, converting the linear movement of the guide plate 27 into a pushing force against the rotating plate 28, thus realizing the conversion and transmission of motion.

[0034] The counter-rotation installation of the two second torsion springs 57 allows the flap 47 to maintain a posture perpendicular to the length of the guide plate 27 without external force, providing a uniform initial reference position for the flap 47 before and after operation, and also enabling the flap 47 to automatically return to its original position after rotation, reducing the reliance on manual reset.

[0035] One end of the flap 47 overlaps with the bottom end of the rotating plate 28 on the projection surface, allowing the two to transmit force through contact. The displacement of the guide plate 27 is directly reflected as the rotation of the rotating plate 28 after being converted by the flap 47, which in turn drives the electrode contact 29 to move closer or further away. The other end of the flap 47 extends to the edge of the through groove 31, creating a position for the locking assembly to limit the rotation state of the flap 47.

[0036] The locking assembly and the rotating plate 28 are placed on the same side of the flip plate 47, so that the locking assembly can form a phased limit on the flip plate 47 and keep the rotating plate 28 in the rotation position corresponding to the insertion rod limit. This avoids the rotating plate 28 from rotating unexpectedly or resetting prematurely due to external force fluctuations during insertion of the insertion rod, and helps to maintain the stable and continuous contact state between the electrode contact 29 and the insertion rod.

[0037] Furthermore, the locking assembly includes a pressure plate 49 and a locking plate 54. Slide grooves 53 are symmetrically formed on the inner wall of the through groove 31. The slide grooves 53 and the second rotating rod 48 are distributed at both ends of the guide plate 27 in the thickness direction, with the slide groove 53 located at the end furthest from the rotating plate 28. The pressure plate 49 is slidably installed inside the slide groove 53, with its bottom end abutting against the top end of the flip plate 47. A guide rod 50 is slidably inserted through the top of the pressure plate 49, with its top end fixedly connected to the inner top wall of the through groove 31. A return spring 51 is slidably sleeved on the guide rod 50, with both ends of the return spring 51 fixedly connected to the pressure plate 49 and the inner top wall of the through groove 31, respectively. A sliding cavity is provided in the guide plate 27 located at the top of the slide groove 53, and the sliding cavity is connected to the slide groove 53. Two spaced locking plates 54 are rotatably arranged inside the sliding cavity via a pin. 4. A tension spring 56 is connected between the two locking plates 54. The tension spring 56 keeps the end of the locking plate 54 at the top of the slide groove 53. The locking plate 54 limits the displacement of the pressure plate 49 in the slide groove 53. A protrusion 55 is provided on the opposite surface between the two locking plates 54. A guide groove is provided on the bottom plate of the sliding cavity between the two locking plates 54 by means of a sinking. A push rod 52 is slidably arranged in the guide groove. The two sides of the push rod 52 abut against the two protrusions 55 respectively. A return spring 59 is elastically connected between the inner top wall of the guide groove and the push rod 52. The other end of the push rod 52 slides through the guide plate 27 and extends to its outside. A protrusion 58 is fixed on the inner upper wall of the guide groove 22. During the movement of the guide plate 27, the protrusion 58 abuts against the push rod 52. The moving push rod 52 pushes the two locking plates 54 away from the top of the slide groove 53.

[0038] The sliding groove 53 and the second rotating rod 48, which are symmetrically opened on the inner wall of the through groove 31, are located at the two ends of the guide plate 27 in the thickness direction. The pressure plate 49 is slidably installed inside the sliding groove 53 and its bottom end abuts against the top of the flip plate 47, so that when the flip plate 47 rotates, it can exert an upward pushing force on the pressure plate 49. The guide rod 50 and the return spring 51 sleeved on the top of the pressure plate 49 provide guiding constraints for the sliding of the pressure plate 49, and cause the pressure plate 49 to return to its original position along the guide rod 50 after the external force is released.

[0039] The two locking plates 54, which are rotatably mounted in the sliding cavity via pins, are held at the top of the slide groove 53 by the tension of the tension spring 56. This limits the position of the pressure plate 49 in the slide groove 53, thereby indirectly constraining the rotation of the flip plate 47. This allows the rotating plate 28 to be maintained at the rotation position corresponding to the insertion rod limit, reducing the possibility of the pressure plate 49 accidentally shifting due to external vibration or reaction force, which could cause the rotating plate 28 to reset prematurely.

[0040] The push rod 52 is slidably disposed in the guide groove between the two locking plates 54, and its two sides abut against the protrusions 55 on the opposite surfaces of the locking plates 54 respectively. When the guide plate 27 moves to the position of the protrusion 58, the protrusion 58 abuts against the push rod 52, and the push rod 52 is thus pushed into the depth of the guide groove and compresses the return spring 59. After the protrusions 55 on both sides are squeezed, they drive the two locking plates 54 to rotate and leave the top of the slide groove 53, releasing the restriction on the pressure plate 49.

[0041] This linkage mechanism ensures that the limiting state of the locking plate 54 against the pressure plate 49 corresponds to the moving position of the guide plate 27 in the guide groove 22, so that the unlocking action of the locking assembly is synchronized with the unlocking movement of the guide plate 27, reducing the reliance on separate unlocking operations; the return spring 59 can drive the push rod 52 to reset after the external force is released, providing conditions for the locking plate 54 to return to the limiting state, taking into account the adaptability of the locking assembly to switch back and forth between the locking and unlocking states.

[0042] Further, the contact voltage engagement mechanism includes an electrode plate 41, a return spring 43, and an electrode contact plate 44; a first protrusion 40 is fixed on one side of the bottom end of the guide plate 27, and an electrode plate 41 is installed on the outside of one side of the first protrusion 40. A second protrusion 42 is provided on the electrode plate 41 in a vertically offset manner relative to the first protrusion 40; an electrode contact plate 44 is installed on the outside of the electrode plate 41 on the side away from the second protrusion 42; a return spring 43 is connected to one side of the electrode plate 41, and the other end of the return spring 43 is connected to the inner wall of the first connector 11; an arc-extinguishing grid 68 is provided on the outside of one side of the electrode contact plate 44; the electrode contact plate 44 is electrically connected to the power supply input terminal, and the electrode plate 41 is electrically connected to the electrode contact plate 29.

[0043] The contact connection mechanism directly links the power on / off with the movement of the guide plate 27, enabling the power supply action to be automatically completed through a mechanical limiting process, eliminating the need for additional manual operation or independent switch control, thus simplifying the operation process. The first protrusion 40 and the second protrusion 42 achieve the deflection of the electrode plate 41 through a staggered pushing mechanism. This structure ensures that the timing of establishing the electrical connection is consistent with the placement process of the electrical connection plug 15, which can, to a certain extent, guarantee that the electrode contact plate 29 only receives power after the plug is in place.

[0044] The reset spring 43 provides a stable reset driving force for the electrode plate 41, so that the electrode plate 41 can reliably separate from the electrode contact plate 44 after the first protrusion 40 separates from the second protrusion 42, cut off the power supply circuit, and reduce the risk of continuous power supply caused by contact parts sticking or residual contact.

[0045] The arc-extinguishing grid 68 is disposed on the outer side of the electrode contact plate 44 to divide and guide the electric arc that may be generated at the moment of separation between the electrode plate 41 and the electrode contact plate 44. This helps to reduce the concentrated release of electric arc energy and has a certain inhibitory effect on the ablation of the contact surface, thereby slowing down the aging rate of the electrode contact plate 44 and the electrode plate 41.

[0046] Furthermore, the electrical connection between electrode plate 41 and electrode contact plate 29 makes the contact voltage connection mechanism an intermediate conductive link connecting the power supply input terminal and the end contact, converting mechanical action into electrical state switching, and providing a structural basis for the entire connector to realize the timing logic of "mechanical limit first, then electrical conduction" and "power off first, then limit release".

[0047] Furthermore, the power mechanism includes pressure rods 60, toothed plates 64, and gears 66, as well as a return spring 63; two pressure rods 60 are symmetrically arranged on the same radial plane of the first connector 11, and the pressure rods 60 slide through the housing of the first connector 11 and extend to the outside; the end of the rotating shaft 39 is rotatably mounted on the inner wall of the first connector 11, and a gear 66 is fixed on the rotating shaft 39, with the gear 66 located between the two pressure rods 60; toothed plate frames are respectively provided on the inner ends of the two pressure rods 60. Each toothed plate frame is arranged in an array with gear 66 as the center; the toothed plate frame includes a horizontal plate 61 fixed to the end of the pressure rod 60, one end of the horizontal plate 61 is vertically connected to the guide plate 65, and the other end of the horizontal plate 61 is vertically connected to the toothed plate 64, the toothed plate 64 meshes with the gear 66, and the guide plate 65 and the toothed plate 64 slide in the corresponding guide grooves respectively; a guide post 62 slides through the bottom end of the horizontal plate 61, and the other end of the guide post 62 is fixedly connected to the inner wall of the first connector 11, and a return spring 63 is sleeved on the guide post 62.

[0048] The power mechanism converts the opposing movement of the two pressure rods 60 into the rotation of the gear 66, which in turn drives the cam 23 to rotate via the rotating shaft 39, providing a driving source for the unlocking movement of the guide plate 27.

[0049] The two toothed plate frames are arranged symmetrically with the gear 66 as the center, so that the force of the pressure rods 60 on both sides can be transmitted synchronously and cancel each other out radial components. The gear 66 rotates more smoothly under the joint meshing drive of the toothed plates 64 on both sides, reducing the deflection or jamming that may be caused by unilateral force.

[0050] The guide plate 65 and the toothed plate 64 slide in their respective guide grooves, which constrains the motion trajectory of the horizontal plate 61, so that the linear motion of the pressure rod 60 can be accurately converted into the displacement of the toothed plate 64 along a predetermined path, thereby ensuring the stability of the meshing transmission with the gear 66.

[0051] The guide post 62 passes through the horizontal plate 61 and is fitted with a return spring 63. After the pressure rod 60 releases the external force, it provides a reset driving force for the horizontal plate 61 and the entire toothed plate frame, so that the pressure rod 60 and the toothed plate 64 can automatically return to the initial position. This makes it easy for the mechanism to return to an operable state after completing one unlocking action without the need for additional manual reset steps.

[0052] Two pressure rods 60 are symmetrically arranged on the same radial plane of the first connector 11. The operator can drive the entire transmission chain to complete the rotation of the cam 23 by applying relative squeezing action to the two pressure caps 24. Compared with the traditional screw-type fixing structure, this power mechanism simplifies the unlocking operation to a shorter stroke linear squeezing action, which is conducive to improving the convenience and efficiency of disassembly operation.

[0053] Furthermore, a pressure cap 24 is fixedly installed at the top of the pressure rod 60, and a limiting pad 25 is detachably sleeved on the pressure rod 60 located between the pressure cap 24 and the outer shell of the first connector 11. The limiting pad 25 and the pressure cap 24 are fixedly connected by a rope 26. The limiting pad 25 is a block-shaped structure with a through-center, and one side of the limiting pad 25 extends outward to form a three-sided opening structure. The limiting pad 25 is made of rubber. A buffer groove is formed at the bottom of the electrode contact 29. A buffer contact 45 is slidably installed inside the buffer groove. The buffer contact 45 is elastically connected to the top wall of the buffer groove by a buffer spring 46. The buffer contact 45 is electrically connected to the electrode 41.

[0054] The limiting pad 25 is fitted between the pressure rod 60 and the pressure cap 24. Under normal use, it blocks the movement of the pressure rod 60, preventing the pressure cap 24 from being accidentally touched or pressed down directly, thus providing a certain degree of protection against accidental contact during the unlocking action.

[0055] The limiting pad 25 is made of rubber and is designed as a block structure with a central through-hole and an outward through-hole on one side, forming three openings. This makes it easy to install and remove along the radial direction of the pressure rod 60. When the operator needs to unlock it, it can be removed more easily without having to perform a complicated disassembly operation.

[0056] The limiting pad 25 and the pressure cap 24 are connected by a rope 26. After being removed, it will not detach from the overall structure, reducing the possibility of subsequent reset installation being affected by the loss of the pad.

[0057] The buffer contact 45 is slidably installed in the buffer groove at the bottom of the electrode contact 29 and is elastically connected to the top wall of the groove through the buffer spring 46. This allows the force exerted when the electrode contact 29 contacts the electrical connector 15 to be absorbed and dispersed to a certain extent by the elastic deformation of the buffer spring 46. This helps to reduce the impact generated at the moment of rigid contact between the two, and provides a certain degree of protection for the contact surfaces of the electrode contact 29 and the electrical connector 15. It also helps to improve the stability of the contact.

[0058] The buffer contact 45 is electrically connected to the electrode 41, so that the buffer structure can achieve mechanical buffering without affecting the current conduction path, thus achieving the synergistic realization of mechanical buffering function and electrical conduction function.

[0059] It should be noted that during the further rotation of the guide plate 27, when there is excess travel, it is absorbed by the buffer spring 46 to avoid interference or jamming.

[0060] Furthermore, the first connector 11 has a socket including a protective socket 14 and two electrical connection sockets 13; the second connector 12 has a plug including a protective plug 16 and two electrical connection plugs 15; the two electrical connection plugs 15 extend into the two electrical connection sockets 13 respectively to form an electrical connection; the protective plug 16 extends into the protective socket 14 to form a protective electrical connection; the protective plug 16 has an irregular shape; a normally connected protective contact 20 is provided at the opening of the protective socket 14; an outer edge 17 is provided on the second connector 12, and a sealing ring 18 is formed on the inner wall of the outer edge 17; an annular groove 19 is formed on the outer wall of the first connector 11, and the sealing ring 18 is pressed into the annular groove 19 to form a seal.

[0061] The first connector 11 has a combination of a protective connector 14 and two electrical connection connectors 13. The protective connector 16 has an irregular shape and is matched with the constant protective contact piece 20 at the opening of the protective connector 14. This allows the electrical connection of the protection circuit to be completed and confirmed before the electrical connection of the electrical connection connector 15, and enhances the identification and prevents incorrect insertion. The sealing ring 18 on the inner wall of the outer edge 17 is pressed together with the annular groove 19 on the outer wall of the first connector 11 to form a sealing structure. While achieving rapid electrical locking, it also takes into account the protective sealing requirements of the connection part and adapts to the usage requirements under various working conditions.

S2. Insert the plug of the second connector 12 into the socket of the first connector 11. The inclined surface 37 at the end of the electric connector 15 pushes the guide plate 27 to move away from the central groove 21 and drives the flip plate 47 to move synchronously. The flip plate 47 pushes the rotating plate 28 to rotate around the first rotating rod 35, causing the buffer contact 45 on the electrode contact 29 to approach and contact the electric connector 15. At the same time, the inner top of the lifting port 30 is engaged in the locking groove 38 to achieve the limit locking of the electric connector 15. S3. During the movement of the guide plate 27, the first protrusion 40 contacts the second protrusion 42 and pushes the electrode plate 41 to deflect, so that the electrode plate 41 contacts the electrode contact plate 44 to form an electrical connection, and the electrode contact plate 29 is energized to complete the quick insertion and locking. S4. When disconnecting, after removing the limit pad 25, drive the two pressure caps 24 to move relative to each other. Drive the gear 66 to rotate through the two toothed plates 64.

The electrode plate 41 separates from the electrode contact plate 44 and the arc is cut off by the arc-extinguishing grid 68. S5, the guide plate 27 continues to move so that the push rod 52 pushes the locking plate 54 to release the limit on the pressure plate 49, the rotating plate 28 is reset by the flip plate 47 and the electrode contact 29 is disengaged from the electric connector 15, and the second connector 12 is pulled out to complete the unlocking and separation.
