Description

Technical Field

[0001] The present invention belongs to the technical field of electric connectors, and in particular is a quick-locking anti-loosening electric connector device. Background Art

[0002] An electrical connector is a device used to establish an electrical connection between circuits, typically consisting of a plug and a socket. The function of an electrical connector is to transmit current and signals while allowing for quick connection and disconnection between devices. There are many types of electrical connectors, with a wide range of applications, from simple household appliances to complex industrial equipment, communications systems, and automotive electronics. They can provide various features as needed, such as waterproofing, dustproofing, vibration resistance, locking, and quick plugging and unplugging.

[0003] Existing technology for quick plugging and unplugging circular electrical connectors typically uses a latch-type locking mechanism to prevent loosening. During this process, environmental factors such as vibration, impact, or other external forces can cause slight displacement of the connector contact points, leading to loosening. Especially in industrial equipment, automobiles, and other high-vibration environments, the connector plug and receptacle may not have sufficient locking force to resist these external forces during plugging and unplugging. Summary of the Invention

[0004] To address the problem of insufficient locking force mentioned in the background art, the present invention provides a quick-locking anti-loosening electrical connector device, in which vibration can cause slight displacement of the contact points between the plug and the socket, resulting in poor contact or insufficient pressure, which in turn affects the locking force of the locking mechanism.

[0007] Preferably, the outer wall of the circular plate is slidably connected to a circular shell, the bottom of the circular shell is fixedly connected to the bottom of the inner wall of the fixed shell, the bottom of the circular plate is fixedly connected to a first extrusion spring, and the bottom of the first extrusion spring is fixedly connected to the bottom of the inner wall of the circular shell.

[0008] Preferably, both sides of the inner wall of the fixed shell are provided with sliding grooves, one side of the rotating member is hinged with a rotating rod, the bottom end of the rotating rod is hinged with a slider, and the outer wall of the slider is slidably connected to the inner wall of the sliding groove.

[0009] Preferably, one side of the slider is fixedly connected to a first connecting plate, one side of the first connecting plate is fixedly connected to a connecting rod, an outer wall of one end of the connecting rod is fixedly connected to a flexible elastic rod, and one flexible elastic rod is provided.

[0010] Preferably, a protection component is provided on the side wall of the slider, and the protection component includes a connecting rod fixedly connected to one side of the slider, and a second connecting rod is fixedly connected to the side wall of one end of the connecting rod.

[0011] Preferably, the end of the second connecting rod away from the connecting frame rod is fixedly connected to a piston plate, the outer wall of the piston plate is slidably connected to a circular shell, the inner wall of the circular shell is fixedly connected to the outer wall of one end of the plug component, and four second extrusion springs are fixedly connected to one side of the piston plate.

[0012] Preferably, one end of the second extrusion spring is fixedly connected to one side of the inner cavity of the annular shell, one side of the piston plate is connected to four elastic telescopic tubes, one end of the elastic telescopic tube is connected to an annular bag, and one side of the outer wall of the annular bag is fixedly connected to one side of the outer wall of the annular shell.

[0013] Preferably, an auxiliary component is provided on one side of the piston plate, and the auxiliary component includes a fixed block fixedly connected to both ends of one side of the piston plate, one end of the fixed block is hinged to a rotating bar, one end of the rotating bar is hinged to a sliding member, and one side of the sliding member is slidably connected to one side of the inner cavity of the annular shell.

[0014] Preferably, one side of the sliding member passes through and is slidably connected to an elastic frame rod, the inner wall of one end of the elastic frame rod is rotatably connected to a round roller, square holes are opened on both sides of the annular shell, and the outer wall of one end of the elastic frame rod is arranged inside the square hole.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a locking assembly, wherein the plug piece is inserted into the interior of the electrical connector shell. During the movement of the plug piece, it is squeezed by the clamping plate, causing the rotating plate to rotate around the fixed rod, and the rotating plate drives the round rod and the rotating piece to rotate. The rotating piece drives the vertical rod and the circular plate to descend almost vertically along the inner wall of the circular shell. At the same time, the rotating piece drives the rotating rod and the slider to slide along the inner wall of the slide groove. The slider drives the first connecting plate and the connecting rod to move, and the connecting rod drives the flexible elastic rod to move. When the clamping hole opened on the rotating plate moves to the top of the clamping hole, it is elastically squeezed by the first extrusion spring, causing the rotating plate to move slightly upward. During the upward movement of the rotating plate, the clamping plate is clamped at the inner wall of the clamping hole, so that the plug hole of the plug piece is inserted into the socket in the inner wall of the electrical connector shell for quick locking, effectively preventing the connector from accidentally falling off due to vibration or external force. When the rotating plate moves slightly upward, the rotating part drives the slider in the locking assembly to move in the opposite direction inside the slide groove, the slider drives the first connecting plate and the connecting rod to move, and the connecting rod drives the flexible elastic rod to move. During the movement of the flexible elastic rod, it will contact the side of the outer wall of the card plate that enters the card hole. Due to the multiple card grooves provided on the outer wall of the card plate, the flexible elastic rod can contact and lock with the outer wall of the card plate, effectively preventing the card plate from loosening due to insufficient friction or other reasons, thereby ensuring the reliability and stability of the connector during long-term use.

[0016] The present invention utilizes a locking assembly and a protective assembly. When the vertical rod drives the circular plate downward and the slider gradually moves away from the circular shell, the slider drives the connecting rod and the second connecting rod to move. The second connecting rod drives the piston plate to slide inside the circular shell, allowing airflow inside the circular shell to enter the interior of the elastic telescopic tube. The airflow enters the annular bladder through the elastic telescopic tube, causing the bladder to slightly expand. When the plug and socket are plugged in, the annular bladder contacts the inner wall of the electrical connector shell, providing a buffering effect for the socket and plug. This helps reduce the impact force during the plug insertion process, avoiding potential mechanical damage to the electrical connector shell and the socket, or damage to internal electrical components.

[0017] The present invention utilizes a protective assembly and an auxiliary assembly to coordinate. When the piston plate slides inside the annular shell, the piston plate drives the fixed block to move. The fixed block drives the rotating bar and the sliding member to slide laterally along the inner cavity of the annular shell. The sliding member drives the elastic frame rod to move. The elastic frame rod drives the circular roller to move, allowing the circular roller to contact the inner wall of the electrical connector shell. The two circular rollers squeeze and support the inner wall of the electrical connector shell. When the socket and plug are inserted, the plug can be effectively prevented from rocking left and right after insertion. This means that the connection is more stable, avoiding poor contact or unstable electrical performance caused by a loose plug. Due to the rolling arrangement of the circular roller, when the plug is inserted into the electrical connector shell, the outer wall of the circular roller rotates against the inner wall of the electrical connector shell, preventing excessive friction between the circular roller and the interior of the electrical connector shell, thereby facilitating the insertion of the plug into the socket.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 10 As shown, the present invention provides a quick-locking anti-loosening electrical connector device, comprising an electrical connector shell 1 and a plug member 2, wherein a clamping plate 3 is fixedly connected to the top of the inner wall of the electrical connector shell 1, a socket 6 is fixedly connected to one end of the inner wall of the electrical connector shell 1, and a fixed shell 4 is fixedly connected to the top of the plug member 2, and further comprising; The quick locking mechanism 5 includes a fixed rod 51 fixedly connected to both sides of the inner wall of the fixed shell 4, and a rotating plate 52 is rotatably connected to the outer wall of the middle end of the fixed rod 51. A card hole 53 is provided on the top of the rotating plate 52, and a locking assembly 54 is provided on one side of the rotating plate 52 to prevent the electrical connector shell 1 and the plug member 2 from loosening when plugging.

[0022] During the insertion of the plug member 2 into the electrical connector housing 1, the plug member 2 is squeezed by the retaining plate 3, causing the rotating plate 52 to rotate about the fixed rod 51. The rotating plate 52 drives the round rod 541 and the rotating member 542 to rotate together. The rotating member 542, in turn, drives the vertical rod 543 and the circular plate 545 to descend almost vertically along the inner wall of the circular housing 544. Simultaneously, the rotating member 542 drives the rotating rod 548 and the slider 549 to slide along the inner wall of the slide slot 547. The slider 549 drives the first connecting plate 5410 and the connecting rod 5411 to move, and the connecting rod 5411 displaces the flexible spring rod 5412. When the latching hole 53 on the rotating plate 52 moves to the top of the latching hole 3, it is elastically squeezed by the first compression spring 546, causing the rotating plate 52 to move slightly upward. During this process, the retaining plate 3 engages the inner wall of the latching hole 53, achieving a quick locking connection between the socket 6 and the plug member 2.

[0023] It is worth noting that when the rotating plate 52 drives the round rod 541 to rotate with the rotating member 542, the rotating member 542 will drive the vertical rod 543 to descend. Due to its small size, the vertical rod 543 descends almost vertically without getting stuck, which will not be described in detail here.

[0024] The locking assembly 54 includes a round rod 541 that passes through one side of the rotating plate 52. The outer walls of both ends of the round rod 541 are rotatably connected to rotating parts 542. The bottom of the rotating part 542 is fixedly connected to a vertical rod 543. The bottom of the vertical rod 543 is fixedly connected to a round plate 545.

[0025] The outer wall of the circular plate 545 is slidably connected to the circular shell 544, the bottom of the circular shell 544 is fixedly connected to the bottom of the inner wall of the fixed shell 4, the bottom of the circular plate 545 is fixedly connected to the first extrusion spring 546, and the bottom of the first extrusion spring 546 is fixedly connected to the bottom of the inner wall of the circular shell 544.

[0026] Slide grooves 547 are provided on both sides of the inner wall of the fixed shell 4, a rotating rod 548 is hinged on one side of the rotating member 542, and a slider 549 is hinged on the bottom end of the rotating rod 548. The outer wall of the slider 549 is slidably connected to the inner wall of the slide groove 547.

[0027] One side of the slider 549 is fixedly connected to the first connecting plate 5410 , one side of the first connecting plate 5410 is fixedly connected to the connecting rod 5411 , and one end outer wall of the connecting rod 5411 is fixedly connected to the flexible elastic rod 5412 , which is provided with one.

[0028] With this solution, when the rotating plate 52 moves slightly upward, the rotating member 542 drives the slider 549 in the locking assembly 54 to move in the opposite direction within the slide slot 547. The slider 549 then drives the first connecting plate 5410 and the connecting rod 5411 to move together, and the connecting rod 5411 causes the flexible spring rod 5412 to move. During the movement of the flexible spring rod 5412, it contacts the outer wall of the card plate 3 within the retaining hole 53. Because the outer wall of the card plate 3 is provided with multiple retaining grooves, the flexible spring rod 5412 can smoothly contact the outer wall of the card plate 3 and lock into place, effectively preventing the card plate 3 from loosening due to insufficient friction or other reasons.

[0029] like Figures 1 to 10 As shown, a protective assembly 55 is provided on the side wall of the slider 549 . The protective assembly 55 includes a connecting rod 551 fixedly connected to one side of the slider 549 , and a second connecting rod 552 is fixedly connected to the side wall of one end of the connecting rod 551 .

[0030] The end of the second connecting rod 552 away from the connecting frame rod 551 is fixedly connected to the piston plate 553, the outer wall of the piston plate 553 is slidably connected to the annular shell 554, the inner wall of the annular shell 554 is fixedly connected to the outer wall of one end of the plug component 2, and four second extrusion springs 555 are fixedly connected to one side of the piston plate 553.

[0031] One end of the second extrusion spring 555 is fixedly connected to one side of the inner cavity of the annular shell 554, one side of the piston plate 553 is connected to four elastic telescopic tubes 557, one end of the elastic telescopic tube 557 is connected to an annular bag 556, and one side of the outer wall of the annular bag 556 is fixedly connected to one side of the outer wall of the annular shell 554.

[0032] As vertical rod 543 drives circular plate 545 downward, slider 549 gradually moves away from circular housing 544, driving connecting rod 551 and second connecting rod 552 to move together. Second connecting rod 552 causes piston plate 553 to slide within annular housing 554, pushing airflow within annular housing 554 into elastic tube 557. Airflow passes through elastic tube 557 and enters annular capsule 556, causing it to expand slightly. When plug 2 is plugged into socket 6, annular capsule 556 contacts the inner wall of electrical connector housing 1, providing a cushioning effect between socket 6 and plug 2, reducing the impact of direct contact and ensuring a smoother plugging process.

[0033] An auxiliary component 56 is provided on one side of the piston plate 553. The auxiliary component 56 includes a fixed block 561 fixedly connected to both ends of one side of the piston plate 553. One end of the fixed block 561 is hinged to a rotating bar 562. One end of the rotating bar 562 is hinged to a sliding member 563. One side of the sliding member 563 is slidably connected to one side of the inner cavity of the annular shell 554.

[0034] An elastic rod 564 is passed through and slidably connected to one side of the sliding member 563, and a circular roller 565 is rotatably connected to the inner wall of one end of the elastic rod 564. Square holes 566 are opened on both sides of the annular shell 554, and the outer wall of one end of the elastic rod 564 is set inside the square hole 566.

[0035] With this solution, when piston plate 553 slides within annular housing 554, it drives fixed block 561 with it, which in turn drives rotating bar 562 and sliding member 563 to slide laterally along the inner cavity of annular housing 554. Sliding member 563 displaces elastic rod 564, which in turn pushes roller 565, bringing it into contact with the inner wall of electrical connector housing 1. The compressive support provided by the two rollers 565 against the inner wall of electrical connector housing 1 effectively prevents side-to-side movement of plug 2 after complete insertion, once receptacle 6 and plug 2 are fully engaged.

[0036] The working principle and use process of the present invention: like Figure 5 As shown in the front cross-sectional structural diagram, the plug member 2 is inserted into the interior of the electrical connector shell 1. During the movement of the plug member 2, it is squeezed by the card plate 3, causing the rotating plate 52 to rotate around the fixed rod 51. The rotating plate 52 drives the round rod 541 and the rotating member 542 to rotate. The rotating member 542 drives the vertical rod 543 and the circular plate 545 to descend almost vertically along the inner wall of the circular shell 544. At the same time, the rotating member 542 drives the rotating rod 548 and the slider 549 to slide along the inner wall of the slide groove 547. The slider 549 with The first connecting plate 5410 and the connecting rod 5411 are moved, thereby pushing the flexible elastic rod 5412 to move. When the card hole 53 opened on the rotating plate 52 moves to the top of the card plate 3, it is elastically squeezed by the first extrusion spring 546, causing the rotating plate 52 to move slightly upward. During the upward movement of the rotating plate 52, the card plate 3 is clamped on the inner wall of the card hole 53, so that the socket of the plug component 2 is inserted into the socket 6 in the inner wall of the electrical connector shell 1 for quick locking, effectively preventing the connector from accidentally falling off due to vibration or external force. When the rotating plate 52 moves slightly upward, the rotating member 542 drives the slider 549 in the locking assembly 54 to move in the opposite direction inside the slide groove 547, and the slider 549 drives the first connecting plate 5410 and the connecting rod 5411 to move, and the connecting rod 5411 drives the flexible elastic rod 5412 to move. During the movement, the flexible elastic rod 5412 will contact the side of the outer wall of the card plate 3 entering the card hole 53. Due to the multiple card grooves set on the outer wall of the card plate 3, the flexible elastic rod 5412 can contact and lock with the outer wall of the card plate 3. Through the combination of the flexible elastic rod 5412 and the rotating plate 52, the card plate 3 can be effectively prevented from loosening due to insufficient friction or other reasons, thereby ensuring the reliability and stability of the connector during long-term use.

[0037] When the vertical rod 543 drives the circular plate 545 to descend, the slider 549 gradually moves away from the circular shell 544. The slider 549 drives the connecting rod 551 and the second connecting rod 552 to move. The second connecting rod 552 drives the piston plate 553 to slide inside the annular shell 554, so that the airflow inside the annular shell 554 enters the interior of the elastic telescopic tube 557. The airflow enters the interior of the annular capsule 556 through the elastic telescopic tube 557, causing the annular capsule 556 to expand slightly. When the plug 2 and the socket 6 are plugged in, as shown in FIG. Figure 7 As shown in the top cross-sectional structural diagram of FIG, the annular pocket 556 contacts the inner wall of the electrical connector housing 1, providing a cushioning effect for the receptacle 6 and the plug 2. This helps reduce the impact force during the insertion of the plug 2, preventing possible mechanical damage to the electrical connector housing 1 and the receptacle 6, or damage to internal electrical components.

[0038] like Figure 7-Figure 8 As shown in the top cross-sectional structural diagram, when the piston plate 553 slides inside the annular shell 554, the piston plate 553 drives the fixed block 561 to move, and the fixed block 561 drives the rotating bar 562 and the sliding member 563 to slide laterally along the inner cavity of the annular shell 554. The sliding member 563 drives the elastic frame rod 564 to move, and the elastic frame rod 564 drives the round roller 565 to move, so that the round roller 565 can contact the inner wall of the electrical connector shell 1. The two round rollers 565 squeeze and support the inner wall of the electrical connector shell 1. When the socket 6 and the plug 2 are inserted, the plug 2 can be effectively prevented from shaking left and right after insertion. This means that the connection state is more stable, avoiding poor contact or unstable electrical performance caused by loose plug 2. Due to the rolling setting of the round roller 565, when the plug component 2 is inserted into the interior of the electrical connector shell 1, the outer wall of the round roller 565 rotates on the inner wall of the electrical connector shell 1, which can prevent excessive friction between the round roller 565 and the interior of the electrical connector shell 1, making it easier for the plug component 2 to be inserted into the socket 6.
