Description

Technical Field

[0001] This invention relates to a connector, and more particularly to a quick-connect connector for emergency power supply in smart grids, used in the field of connection devices. Background Technology

[0002] In emergency power supply scenarios of smart grids, quick-release connectors for mobile generator vehicles connected to user-end power access boxes can achieve rapid and stable power supply. Traditional connectors mostly use threaded fastening or elastic locking pins. Their rigid connection structure between the plug and socket has significant defects when the cable is pulled by external force: when the access cable is displaced due to accidental contact during construction or environmental vibration, the metal threads of the threaded connection are prone to deformation due to stress concentration, while the elastic locking pin may fail to lock due to metal fatigue. This rigid connection mode will directly transmit the pulling force to the busbar inside the power access box, which may cause the copper busbar welding points to fall off, the insulation layer to break, or even the entire equipment to be damaged.

[0003] The existing patent with publication number CN117878658B discloses a quick-connect terminal connector. By setting a movable mating structure between the male and female plug sockets in the quick-connect terminal connector, the male terminal tube can move while the female terminal is fixed and corresponding. At the same time, it gives the terminal an extension function, so that the terminals can be accurately aligned during connection, effectively avoiding deformation damage to the connected terminals. The optimized structural design enables the connector to be easily separated, thereby improving the efficiency of disassembly. In addition, by adding a wire rotation buffer mechanism, the wire insulation layer and conductive core are prevented from cracking and being damaged due to swing fatigue. Ultimately, it achieves the comprehensive effect of improving the convenience of connector insertion and removal, ensuring terminal safety, extending service life, and enhancing overall reliability.

[0004] A patent with publication number CN110932017B discloses a quick-connect energy storage connector. It employs a hollow cylindrical pin structure with slots within the connector socket, and incorporates a combination of contact pieces with contacts. The contact is controlled by the extension and retraction of a spring within the contact pieces, significantly increasing the contact area between the pins and the socket, thereby improving current carrying capacity and reducing contact temperature rise. A simple locking device, consisting of a locking button, a locking spring, and an annular groove on the socket housing, allows the plug and socket to rotate 360 ​​degrees after mating, enabling flexible wiring. An alternative locking solution using a threaded nut provides even force distribution and a secure connection. A sealing ring within the plug housing provides waterproofing, ultimately enhancing the connector's electrical performance, usability, and environmental adaptability.

[0005] The prior art disclosed above includes extendable terminals, which reduces the probability of terminals being easily damaged. It also discloses a simple locking device to realize the rotational connection of the plug and socket, reducing the probability of cable damage. However, the cables of the connectors in the prior art are easily damaged when pulled. Summary of the Invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the cables of existing connectors are easily damaged when they are pulled.

[0007] To address the aforementioned issues, this invention provides a quick-connect connector for emergency power supplies in smart grids, comprising a socket and a plug that are interlocked. A conductive terminal one is fixedly connected to the center of the socket, and a conductive terminal two that is plugged into the plug is fixedly connected to the plug. The socket has a plug-in cylinder located outside the conductive terminal one, and a plug-in hole is provided on the inner wall of the plug-in cylinder. The plug has a lifting plate that slides radially within it, and a plug-in post that is plugged into the plug-in hole is fixedly connected to the outer end of the lifting plate. A pressing rod extending to the outside of the plug is fixedly connected to the end of the lifting plate away from the plug-in post. The right end of the conductive terminal two is fixedly connected to an access cable that passes through the plug. The access cable is fixedly sleeved with a sliding frame that is axially slidably connected to the plug and extends to the outside of the plug. The sliding frame abuts against a spring one that abuts against the inner wall of the plug. Under the action of the spring one, the part of the access cable located inside the plug forms a bent part. The right end of the lifting plate is fixedly connected to a traction rod. The right end of the traction rod is fixedly connected to a sliding column. The sliding column is slidably connected to a groove plate. The right end of the groove plate is fixedly connected to the left side wall of the sliding frame. The groove plate is used to drive the sliding column to move up and down.

[0008] In the aforementioned quick-connect connector for emergency power supply in smart grids, a sliding bracket that is linked to the plug post and fixedly connected to the access cable allows the plug to actively detach from the socket when subjected to significant force.

[0009] As a further improvement of this application, the sliding frame includes a socket sleeve fixedly sleeved on the outside of the access cable and a sliding cylinder slidably sleeved on the left end of the socket sleeve. The groove plate is fixedly connected to the left outer wall of the sliding cylinder. Spring 1 abuts against the socket sleeve. The pressing rod has a T-shaped cross section and a spring 3 that abuts against the outer wall of the plug is sleeved on the pressing rod.

[0010] As a further improvement of this application, the inner side of the spring is provided with a guide cylinder that is fixedly connected to the inner wall of the plug, and a sliding disc is slidably connected to the outer side of the guide cylinder. The sliding disc abuts against the right end of the spring, and an adjusting bolt extending to the outer side of the plug is rotatably connected to the right end of the sliding disc. The adjusting bolt is threadedly connected to the plug.

[0011] As a further improvement of this application, the plug has a plug cavity for inserting the plug tube, and the plug has a radial cavity communicating with the plug cavity on the right side of the plug cavity, and the plug has an installation cavity communicating with the radial cavity on the right side of the radial cavity; the lifting plate is nested in the radial cavity and slides against the inner wall of the radial cavity, and the sliding frame is slidably nested in the installation cavity and slides against the inner wall of the installation cavity.

[0012] As a further improvement of this application, the right end opening of the plug tube is provided with a conical surface, the outer end of the plug post is spherical, and the slot plate is provided with a guide groove for the sliding post to slide. The guide groove is a strip-shaped through groove that penetrates the slot plate and is an inclined groove that is higher on the left and lower on the right.

[0013] As a further improvement of this application, the slot plate is a rectangular plate, the horizontal cross section of the traction rod is U-shaped, and the sliding column is fixed at the opening position on the right end of the traction rod. The left end of the plug is fixedly connected to a positioning rod, and the socket is provided with a positioning hole for the positioning rod to be inserted.

[0014] As a further improvement of this application, the sleeve is a frustum-shaped structure with a horizontal T-shaped cross-section, and a through hole with a radius larger than that of the access cable is opened at the center of the sliding sleeve.

[0015] As a further improvement of this application, a limiting rod slides through the nut of the adjusting bolt. A protruding ring is fixedly connected to the outer wall of the limiting rod near the plug. A spring two is provided between the protruding ring and the nut of the adjusting bolt and sleeved on the limiting rod. A locking hole with a uniform circumferential distribution is opened on the right side wall of the plug. The limiting rod is inserted into the locking hole under the action of the spring two.

[0016] As a further improvement of this application, the outer side of the pressing rod is slidably abutted against a guide plate that is fixedly connected to the outer wall of the plug. The guide plate is an arc-shaped plate with a semi-circular cross-section. After the plug is inserted into the plug hole, the upper end of the pressing rod is flush with the upper end of the guide plate.

[0017] In summary, this invention, through a curved access cable and a sliding frame fixedly sleeved on the outside of the access cable and sliding axially with the plug, allows the access cable to be stretched when pulled, replacing the traditional rigid connection between the cable and connector. This improves the connection stability of the access cable and conductive terminals when the access cable is pulled, protecting the access cable and connector body. Simultaneously, through the plug pin linked to the sliding frame, when the pulling force on the access cable exceeds the cable pull-out force, the sliding frame causes the plug pin to disengage from the plug hole of the plug sleeve, thus disengaging the plug and socket. This replaces the traditional rigid connection between the socket and plug, reducing the probability of damage to the socket, plug, and access cable due to pulling, and improving the safety of connector use. Furthermore, the sliding frame, including the sleeve and sliding cylinder, increases the axial stretching range of the access cable, improving the connection stability of the plug and socket in the initial stage of pulling.

[0020] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0021] Implementation method 1: Figures 1-10A quick-connect connector for emergency power supply of smart grid is shown, including a socket 1 and a plug 2 that are plugged into each other. A conductive terminal 3 is fixedly connected to the center of the socket 1. A conductive terminal 4 that is plugged into the conductive terminal 3 is fixedly connected to the plug 2. A plug tube 101 is provided on the outside of the conductive terminal 3 in the socket 1. A plug hole 102 is opened on the inner wall of the plug tube 101. A lifting plate 6 that slides in the radial direction is provided in the plug 2. A plug post 8 that is plugged into the plug hole 102 is fixedly connected to the outer end of the lifting plate 6. A pressing rod 7 that extends to the outside of the plug 2 is fixedly connected to the end of the lifting plate 6 away from the plug post 8. Please see Figures 3-5 The right end of the conductive terminal 4 is fixedly connected to the access cable 5 that passes through the plug 2. The access cable 5 is fixedly sleeved with a sliding frame 12 that is axially slidably connected to the plug 2 and extends to the outside of the plug 2. The sliding frame 12 abuts against a spring 13 that abuts against the inner wall of the plug 2. Under the action of the spring 13, the part of the access cable 5 located inside the plug 2 forms a bent part. The right end of the lifting plate 6 is fixedly connected to a traction rod 9. The right end of the traction rod 9 is fixedly connected to a sliding column 10. The sliding column 10 is slidably connected to a groove plate 11. The right end of the groove plate 11 is fixedly connected to the left side wall of the sliding frame 12. When the groove plate 11 moves to the right, it pushes the sliding column 10 to move downward. The sliding column 10 drives the lifting plate 6 to move towards the axial center of the plug 2 through the traction rod 9. The lifting plate 6 drives the plug pin 8 to disengage from the plug hole 102 of the plug cylinder 101.

[0022] Specifically, socket 1 is fixedly installed inside the low-voltage power access box. When plug 2 is plugged into socket 1, plug 2 is inserted into socket 1, plug pin 8 is inserted into plug hole 102 of plug tube 101, conductive terminal 3 and conductive terminal 4 are connected, and conductive terminal 4 is electrically connected to external mobile generator through access cable 5. When the access cable 5 is pulled, the access cable 5 drives the sliding bracket 12, which is fixedly connected to it, to move outward along the axial direction of the plug 2. The sliding bracket 12 compresses the spring 13, and the sliding bracket 12 drives the slot plate 11 to move away from the lifting plate 6. The slot plate 11 squeezes the traction rod 9 through the sliding column 10. The traction rod 9 drives the lifting plate 6 to move towards the axial center of the plug 2. The plug pin 8 moves away from the plug hole 102. Whether the plug pin 8 and the plug hole 102 disengage includes the following two situations: Scenario 1: Please refer to Figure 9 When the pulling force on the access cable 5 is less than the cable pull-out force (the pulling force on the access cable 5 when the plug 8 is pulled out of the plug hole 102), the plug 8 cannot be pulled out of the plug hole 102, the socket 1 and the plug 2 remain connected. During the pulling process of the access cable 5, the sliding bracket 12 slides along the axial direction of the plug 2, the spring 13 is compressed, and the bent part of the access cable 5 located in the plug 2 deforms. Scenario 2: Please refer to Figure 10 When the pulling force on the access cable 5 is not less than the cable pull-out force, the plug 8 disengages from the plug hole 102 of the socket 1, and then the plug 2 disengages from the socket 1.

[0023] Compared to traditional quick-connect connectors, this invention uses a curved access cable 5 and a sliding frame 12 fixedly sleeved on the outside of the access cable 5 and sliding axially with the plug 2. When the access cable 5 is pulled, the sliding frame 12 causes the curved access cable 5 to stretch, replacing the traditional rigid connection between the cable and the connector. This improves the connection stability between the access cable 5 and the conductive terminal 2 4 when the access cable 5 is pulled, protecting the access cable 5 and the connector body. At the same time, through the plug post 8 linked with the sliding frame 12, when the pulling force on the access cable 5 is greater than the cable pull-out force, the sliding frame 12 causes the plug post 8 to disengage from the plug hole 102 of the plug sleeve 101, thereby causing the plug 2 and the socket 1 to disengage. This replaces the traditional rigid connection between the socket 1 and the plug 2, reducing the probability of mechanical damage to the socket 1, plug 2, and access cable 5, and improving the safety of connector use.

[0024] Please see Figure 1 and Figure 2 The plug 2 has a plug cavity 201 for inserting the plug tube 101. The plug 2 has a radial cavity 202 on the right side of the plug cavity 201, which communicates with the plug cavity 201. The plug 2 has an installation cavity 203 on the right side of the radial cavity 202, which communicates with the radial cavity 202. The lifting plate 6 is nested in the radial cavity 202 and slides against the inner wall of the radial cavity 202. The sliding frame 12 is slidably nested in the installation cavity 203 and slides against the inner wall of the installation cavity 203.

[0025] Specifically, when plug 2 and socket 1 are plugged in, the plug sleeve 101 of socket 1 is inserted into the plug cavity 201 to improve the plugging and sealing effect. The lifting plate 6 slides radially in the radial cavity 202 to realize the plugging post 8 on the lifting plate 6 and the plugging hole 102 for plugging and disengaging. The sliding frame 12 slides axially in the mounting cavity 203 to realize the compression and release of spring 13.

[0026] Please see Figure 4 and Figure 5 The right end of the plug tube 101 has a conical surface, and the outer end of the plug post 8 is spherical.

[0027] Specifically, after the plug tube 101 is inserted into the plug cavity 201, it contacts the outer end of the plug post 8. The plug tube 101 with a conical surface squeezes the plug post 8 with a spherical tip. The plug post 8 squeezes the sliding frame 12 through the lifting plate 6, the traction rod 9, the sliding column 10, and the slot plate 11. The sliding frame 12 squeezes the spring 13. When the plug post 8 and the plug hole 102 are opposite each other, under the action of the spring 13, the plug post 8 is inserted into the plug hole 102, realizing the snap-fit ​​fixation of the socket 1 and the plug 2. When it is necessary to manually pull out the plug 2, hold the plug 2 and press the pressing rod 7 with your fingers to make the plug post 8 disengage from the plug hole 102. Then drag the plug 2 away from the socket 1 to complete the removal of the plug 2.

[0028] Please see Figure 7 The groove plate 11 has a guide groove 1101 for the sliding column 10 to slide. The guide groove 1101 is a strip-shaped through groove that passes through the groove plate 11. The guide groove 1101 is an inclined groove that is higher on the left and lower on the right.

[0029] Specifically, when the slot plate 11 moves horizontally, the inner wall of the guide groove 1101 of the slot plate 11 presses against the sliding column 10, causing the sliding column 10 to move in the radial direction of the plug 2. The sliding column 10 drives the lifting plate 6 and the plug-in column 8 on it to move radially through the traction rod 9.

[0030] Please see Figure 7 The trough plate 11 is a rectangular plate, the horizontal cross section of the traction rod 9 is U-shaped, and the sliding column 10 is fixed at the opening position on the right end of the traction rod 9.

[0031] Specifically, the lifting plate 6 and the sliding frame 12 are linked by the traction rod 9, the sliding column 10 and the groove plate 11.

[0032] Please see Figure 4 and Figure 5 The left end of the plug 2 is fixedly connected to a positioning rod 21, and the socket 1 has a positioning hole 103 for the positioning rod 21 to be inserted.

[0033] Specifically, the positioning rod 21 and the positioning hole 103 work together to facilitate the alignment of the insertion post 8 and the insertion hole 102.

[0034] The second implementation method: Figures 5-7 A quick-connect connector for emergency power supply of smart grid is shown. Based on the first embodiment, the sliding frame 12 includes a socket 1201 fixedly sleeved on the outside of the access cable 5 and a sliding cylinder 1202 slidably sleeved on the left end of the socket 1201. The groove plate 11 is fixedly connected to the left outer wall of the sliding cylinder 1202. Spring 13 abuts against the socket 1201. The pressing rod 7 has a T-shaped cross section and a spring 3 19 that abuts against the outer wall of the plug 2 is sleeved on the pressing rod 7.

[0035] Specifically, in the initial stage of the pull on the access cable 5, the socket 1201 slides to the right along with the access cable 5, and the bent part of the access cable 5 is stretched. At this time, the sliding cylinder 1202 remains in a fixed position (the spring 19 limits the pressing rod 7, and the pressing rod 7 limits the slot plate 11 and the sliding cylinder 1202 through the lifting plate 6, the traction rod 9, and the sliding column 10). Compared with the first embodiment, the sliding frame 12 has a larger axial movement range and does not cause the plug 8 to move in the initial stage of the pull, which improves the connection stability of the plug 2 and the socket 1 in the initial stage of the stretch and improves the protection effect on the access cable 5. When the left end of the socket 1201 abuts against the right end of the sliding cylinder 1202, the socket 1201 drives the sliding cylinder 1202 to move to the right, the sliding cylinder 1202 drives the slot plate 11 to move to the right, and then guides the plug 8 to disengage from the plug hole 102.

[0036] Please see Figure 7 The sleeve 1201 is a frustum-shaped cylindrical structure with a horizontal T-shaped cross section, and the sliding sleeve 1202 has a through hole with a radius larger than that of the access cable 5 at its center.

[0037] Specifically, the access cable 5 is fixedly connected to the sleeve 1201 and moves synchronously, while the sliding cylinder 1202 is sleeved on the outside of the access cable 5.

[0038] Please see Figure 5 The inner side of the spring 13 is provided with a guide cylinder 14 that is fixedly connected to the inner wall of the plug 2. A sliding disk 15 is slidably connected to the outer side of the guide cylinder 14. The sliding disk 15 abuts against the right end of the spring 13. An adjusting bolt 16 extending to the outer side of the plug 2 is rotatably connected to the right end of the sliding disk 15. The adjusting bolt 16 is threadedly connected to the plug 2.

[0039] Specifically, by turning the adjusting bolt 16, the adjusting bolt 16 drives the sliding plate 15 to move along the axial direction of the plug 2, thereby squeezing or releasing the spring 13 in the initial state, thereby adjusting the initial pressure of the spring 13, thereby adjusting the cable pull-out force of the plug post 8 disengaging from the plug hole 102, and thereby adjusting the maximum disconnection pull force of the connector body.

[0040] Please see Figure 5 and Figure 6 A limiting rod 17 slides through the nut of the adjusting bolt 16. A protruding ring is fixedly connected to the outer wall of the limiting rod 17 near the plug 2. A spring 18 is provided between the protruding ring and the nut of the adjusting bolt 16 and is sleeved on the limiting rod 17. A locking hole 204 with a uniform circumference is opened on the right side wall of the plug 2. The limiting rod 17 is inserted into the locking hole 204 under the action of the spring 18.

[0041] Specifically, the locking and fixing of the adjusting bolt 16 is achieved through the cooperation of the limiting rod 17 and the second spring 18, reducing the probability of the adjusting bolt 16 loosening and improving the stability of the sliding plate 15.

[0042] Please see Figure 5 and Figure 6 The outer side of the pressing rod 7 slides against the guide plate 20 which is fixedly connected to the outer wall of the plug 2. The guide plate 20 is an arc plate with a semi-circular cross section. After the plug post 8 is inserted into the plug hole 102, the upper end of the pressing rod 7 is flush with the upper end of the guide plate 20.

[0043] Specifically, the guide plate 20 facilitates the determination of the relative position of the pressing rod 7, thereby facilitating the determination of whether the insertion post 8 is fully inserted into the insertion hole 102, and reminding the operator to pay attention. In addition, the semi-circular guide plate 20 partially wraps around the pressing rod 7, reducing accidental activation of the pressing rod 7.

[0044] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
