Description

Technical Field

[0001] This utility model relates to the field of circuit connection technology, and in particular to a non-loosening and stable circuit connector. Background Technology

[0002] In modern electronic and electrical systems, circuit connectors, as key components for signal and power transmission, are widely used in communication equipment, industrial control, aerospace, and other fields. Their connection stability and ease of maintenance directly affect the reliability and operational efficiency of the system, and are crucial for the normal operation of the equipment.

[0003] Currently, traditional circuit connectors mostly employ plug-in or snap-fit ​​connection methods in their structural design. During actual use, factors such as vibrations generated during equipment operation and pulling of external cables can easily cause connectors to loosen, leading to problems such as poor circuit contact and signal interruption. Furthermore, to ensure a compact internal structure and sealing, existing connectors are often designed with enclosed interfaces. When internal interface inspection, maintenance, or rewiring is required, specialized tools are typically needed to disassemble the entire connector. This is not only cumbersome but also carries the risk of damaging internal components due to mishandling during disassembly and assembly, increasing maintenance and time costs. To address this technical problem, this application proposes an anti-loosening and stable circuit connector. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a non-loosening and stable circuit connector. Through mechanical transmission and an intelligent feedback structure, it solves the problems of easy loosening and difficult maintenance of traditional circuit connectors. During docking, the sliding plate, in conjunction with the rack and pinion, automatically limits the auxiliary frame to prevent loosening, while the spring and the limiting block provide feedback. Simultaneously, the pressing bushing, in conjunction with the rotating groove, allows for precise rotation of the rotating shaft, enabling quick disassembly of the rotating plate for easy maintenance and effectively improving connection reliability and maintenance efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A non-loosening and stable circuit connector includes a transmission line one and a receiver housing. The right side of the transmission line one is fixedly connected to the left side of the receiver housing. A rubber sleeve is fixedly connected to the outer wall of the transmission line one. A connecting sleeve is fixedly connected to the rear side of the receiver housing. A rotating plate is rotatably connected to the upper side of the receiver housing. A fixing component is provided inside the upper side of the receiver housing. A stabilizing component is provided on the outer wall of the receiver housing. A transmitter is slidably connected to the right side of the receiver housing. A transmission line two is fixedly connected to the rear side of the transmitter.

[0007] Furthermore, the fixing component includes a bushing that is slidably connected to the inside of the upper side of the receiver housing. A rotating shaft is provided inside the bushing, and a horizontal plate is fixedly connected to the upper side of the rotating shaft. A rotating groove is provided on the outer wall of the rotating shaft, and a circular plate is provided inside the rotating groove. The circular plate is fixedly connected to the inner wall of the bushing.

[0008] Furthermore, the stabilizing component includes a gear rotatably connected to the left side of the receiver housing, the outer wall of the gear being fixedly connected to the inside of the auxiliary frame, the gear being meshed with the left side of the rack, a sliding plate being slidably connected to the lower side of the rotating plate, and a rack being fixedly connected to the inside of the left side of the sliding plate.

[0009] Furthermore, a spring is provided on the lower side of the bushing, and the outer wall of the spring is disposed inside the upper side of the receiver housing.

[0010] Furthermore, an insertion groove is provided on the upper side of the rotating plate, and a circular groove is provided on the lower side of the rotating plate.

[0011] Furthermore, a limit block is slidably connected to the left side of the sliding plate, and a spring is provided inside the limit block.

[0012] Furthermore, the sliding plate is slidably connected inside the receiver housing, and a second spring is provided on the right side of the sliding plate.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, a mechanical transmission structure triggered when the transmitter and receiver housings are connected utilizes the movement of a sliding plate to drive the rack and pinion mechanisms, causing the auxiliary frame to automatically engage with the transmitter edge, forming a physical limit and effectively avoiding the loosening problem caused by vibration or external pulling of traditional connectors. Simultaneously, the intelligent feedback system composed of spring two and the limiting block automatically pops out the transmitter to remind the user when the connection is not in place, and locks the structure to maintain stability once in place, significantly improving the reliability and safety of the circuit connection.

[0015] 2. In this utility model, the innovatively designed detachable rotating plate structure significantly simplifies the maintenance process for internal interface maintenance needs. By pressing the bushing hole, the rotating shaft can be precisely rotated 90° with the ingenious cooperation of the spring and the rotating groove, allowing the horizontal plate to disengage from the insertion groove. Users can easily flip the rotating plate to expose the internal structure, completing maintenance without complex tools or professional operation, effectively reducing maintenance and time costs, and meeting the needs of efficient operation and maintenance.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 , Figure 3 and Figure 5 This utility model provides an embodiment of a non-loosening and stable circuit connector, comprising a transmission line 1 and a receiver housing 4. The right side of the transmission line 1 is fixedly connected to the left side of the receiver housing 4. A rubber sleeve 3 is fixedly connected to the outer wall of the transmission line 1. A connecting sleeve 2 is fixedly connected to the rear side of the receiver housing 4. A rotating plate 6 is rotatably connected to the upper side of the receiver housing 4. A bushing 12 is provided inside the upper side of the receiver housing 4. A rotating shaft 9 is provided inside the bushing 12. A horizontal plate 10 is fixedly connected to the upper side of the rotating shaft 9. A rotating groove is formed on the outer wall of the rotating shaft 9. A circular plate 11 is provided inside the rotating groove and is fixedly connected to the inner wall of the bushing 12. A gear 19 is provided on the outer wall of the receiver housing 4. The outer wall of the gear 19 is fixedly connected to the inside of an auxiliary frame 5. The gear 19 is meshed with the left side of a rack 16. A sliding plate 14 is slidably connected to the lower side of the rotating plate 6. A rack 16 is fixedly connected to the left side of the sliding plate 14. A transmitter 7 is slidably connected to the right side of the receiver housing 4. A transmission line 8 is fixedly connected to the rear side of the transmitter 7.

[0025] Specifically, during the use of the device, traditional circuit connectors may have unstable connections, causing the connection to break and affecting use. Therefore, a structural design was designed to assist in stabilization. First, the receiver housing 4 is connected to the transmitter 7. The front of the transmitter 7 can press against the sliding plate 14 inside the receiver housing 4, causing the sliding plate 14 to move backward. During the movement of the sliding plate 14, the internal rack 16 also moves backward, causing the gear 19 that meshes with it to rotate. The auxiliary frame 5 retracts inward. When the transmitter 7 is pressed to the appropriate position, the auxiliary frame 5 will lock onto the edge of the transmitter 7, thus... To prevent the transmitter 7 from becoming loose, and if the transmitter 7 does not reach the proper position, the internally compressed spring 15 will release when released, thereby squeezing the transmitter 7 out, effectively indicating that the device is not properly connected. An internal limit block 18 is designed, which slides inside the receiver housing 4. When it reaches the proper position, it can exit through the hole in the outer wall of the receiver housing 4, thereby limiting the spring 15 from squeezing the sliding plate 14 and maintaining the stable effect of the device. When changing the connection, press the limit blocks 18 on both sides, and the sliding plate 14 will be squeezed out by the action of the spring 15. Considering the potential need for maintenance or wiring work on the internal interfaces of the receiver housing 4, the existing structure is inconvenient. Therefore, a design for easy disassembly was implemented. When disassembly is required, a screwdriver can be used to press the upper hole. Upon release, the internal spring 13 will compress the bushing 12, causing it to move upwards. Because the inner wall of the bushing 12 has a circular plate 11, and the bushing 12 is slidably connected to the inside of the receiver housing 4 and does not rotate, the internal spring 13 will rotate along the up-and-down movement of the circular plate 11. When the horizontal plate 10 on the upper side of the bushing 12 rotates 90°, the side groove is sufficient for the horizontal plate 10 to disengage from the interior of the rotating plate 6, allowing the rotating plate 6 to be flipped over for easy inspection of the interior. In this process, placing the bushing 12 and spring 13 internally effectively prevents accidental contact that could lead to device disassembly. Furthermore, the internal rotating groove is designed with a limit, ensuring that after the circular plate 11 moves to its lowest point, it will only move upwards along the inclined groove, and when pressed down, it will only move along the vertical groove. With each press, the internal rotating shaft 9 rotates 90°.

[0026] Reference Figure 2 and Figure 4 A spring 13 is provided on the lower side of the bushing 12, and the outer wall of the spring 13 is located inside the upper side of the receiver housing 4. An insertion slot is provided on the upper side of the rotating plate 6, and a circular groove is provided inside the lower side of the rotating plate 6. A limit block 18 is slidably connected to the left side of the sliding plate 14, and a spring 17 is provided inside the limit block 18. The sliding plate 14 is slidably connected inside the receiver housing 4, and a spring 15 is provided on the right side of the sliding plate 14.

[0027] Specifically, the second spring 15 on the right side of the sliding plate 14 is connected at both ends to the sliding plate 14 and the inside of the receiver housing 4, respectively. During the docking process between the transmitter 7 and the receiver housing 4, the transmitter 7 presses the sliding plate 14 to move it backward, and the second spring 15 is compressed. If the transmitter 7 is not fully inserted, the elastic force of the second spring 15 will push the sliding plate 14 and the transmitter 7 outward after releasing, indicating that the connection is unsuccessful. When the transmitter 7 reaches the appropriate position, the limiting block 18, which is slidably connected to the left side of the sliding plate 14, pops out through the hole in the outer wall of the receiver housing 4 under the action of the third spring 17, locking the sliding plate 14, restricting the spring 15 from rebounding, and maintaining a stable connection of the transmitter 7. During disassembly, press the limiting blocks 18 on both sides to retract them into the sliding plate 14, release the lock, and the second spring 15 will then push the sliding plate 14 to squeeze out the transmitter 7. The upper insertion slot and lower circular groove of the rotating plate 6 are used to accommodate parts of the structure of the horizontal plate 10 and the sliding plate 14, respectively. While realizing the rotation function, it ensures the precise cooperation of the sliding and rotation of each component. When the screwdriver is inserted into the insertion slot and the bottom bushing 12 is pressed, the rotating shaft 9, the horizontal plate 10 and the outer wall rotating groove will rotate under the action of the circular plate 11. The rotating shaft 9 will rotate inside the insertion slot and the horizontal plate 10 will rotate inside the circular groove. After rotating 90°, the circular plate 11 can be released from the constraint of the rotating plate 6 from the groove opening on the lower side of the circular groove.

[0028] Working principle: When the transmitter 7 is connected to the receiver housing 4, the front of the transmitter 7 presses against the sliding plate 14 inside the receiver housing 4, causing it to move backward. The movement of the sliding plate 14 drives the internal rack 16 to move backward synchronously, and the gear 19 meshing with the rack 16 rotates accordingly, thereby driving the auxiliary frame 5 to retract inward. When the transmitter 7 is pressed to the appropriate position, the auxiliary frame 5 engages with the edge of the transmitter 7, forming a physical limit to prevent it from loosening. During this process, if the transmitter 7 is not fully inserted, the second spring 15 on the right side of the sliding plate 14 is in a compressed state. After releasing, the second spring 15 releases its elasticity, pushing the sliding plate 14 and the transmitter 7 outward, indicating a connection failure. When the transmitter 7 is in place, the limiting block 18 on the left side of the sliding plate 14, under the action of the third spring 17, pops out through the hole in the outer wall of the receiver housing 4, locking the sliding plate 14, limiting the rebound of the second spring 15, and maintaining a stable connection of the transmitter 7. When maintenance or wiring work is required on the internal interface of the receiver housing 4, press the upper hole of the bushing 12 with a screwdriver. The spring 13 on the lower side of the bushing 12 is compressed, and the bushing 12 slides upward. Due to the cooperation between the inner wall circular plate 11 of the bushing 12 and the rotating groove of the rotating shaft 9, when the spring 13 pushes the bushing 12 back to its original position after releasing the screw, the rotating shaft 9 rotates 90°, causing the horizontal plate 10 on the upper side of the bushing 12 to disengage from the insertion groove on the upper side of the rotating plate 6. At this time, the rotating plate 6 can be flipped over to expose the internal structure for maintenance. When disassembling the transmitter 7, press the limit blocks 18 on both sides to retract them into the sliding plate 14 to release the lock. The spring 15 pushes the sliding plate 14 to squeeze out the transmitter 7, completing the separation.
