Description

Technical Field

[0001] This invention relates to the field of cable splicing technology, specifically to a quick splicing device for video equipment cable interfaces with a self-locking function. Background Technology

[0002] In modern imaging equipment applications, cable interface connectors are crucial components for signal transmission, and their performance directly impacts the stability and efficiency of the equipment. Currently, most imaging equipment cable interfaces on the market employ traditional plug-and-play connection structures, achieving electrical connection through metal contacts. These interfaces typically include an insulating shell, internal terminals, and a simple mechanical locking mechanism, and are widely used in medical imaging equipment, industrial testing equipment, and professional video equipment. As imaging equipment evolves towards higher resolution and higher frame rates, higher demands are placed on the transmission bandwidth and connection reliability of the interfaces. Traditional connectors are prone to problems such as poor contact and signal attenuation under frequent plugging and unplugging conditions.

[0003] Existing imaging equipment cable interface docking devices have the following main technical defects: First, the mechanical locking structure design is too simple and lacks an effective self-locking function, which can easily lead to loosening or even detachment of the connection under equipment vibration or accidental pulling; Second, the existing docking devices are not convenient to operate, and cannot achieve quick plugging and unplugging, nor can they ensure the stability of the connection. Therefore, we propose a quick docking device for imaging equipment cable interfaces with a self-locking function. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a quick docking device for the cable interface of imaging equipment with self-locking function. It has self-locking function and can be quickly plugged in and unplugged, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a quick docking device for the cable interface of imaging equipment with self-locking function, comprising a first insulating shell and a snap-fit ​​assembly;

[0006] First insulating shell: A first terminal block is fixed inside the first insulating shell. A first connecting cable is fixed to the right end of the first insulating shell and connected to the first terminal block. A second insulating shell is provided on the left side of the first insulating shell. A second terminal block is fixed inside the second insulating shell and snapped together with the first terminal block. A second connecting cable is fixed to the left end of the second insulating shell and connected to the second terminal block. A toggle assembly is installed on the right end of the surface of the second insulating shell. A connecting assembly is installed on the right end of the toggle assembly. A reset assembly is installed on the left end of the surface of the second insulating shell. The reset assembly is connected to the toggle assembly. A fixing assembly is installed inside the toggle assembly. A rotating assembly is installed on the circumferential surface of the toggle assembly.

[0007] The snap-fit ​​assembly includes a retaining ring and a pressing block. The retaining ring is fixed to the surface of the first insulating shell. An opening is provided at the left end of the retaining ring. The pressing block is fixed inside the opening. The retaining assembly is connected to the pressing block.

[0008] Furthermore, the actuating component includes a rotating ring, an annular groove, and a pull strap. The rotating ring is rotatably connected to the right end of the surface of the second insulating shell. An annular groove is formed on the circumferential surface of the rotating ring, and a pull strap is provided inside the annular groove. The actuating component drives the connecting component to rotate.

[0009] Furthermore, the connecting assembly includes an arc-shaped plate and a limiting block. The right end of the rotating ring is fixed with an arc-shaped plate, which is located inside the opening at the left end of the fixed ring. The side of the arc-shaped plate is fixed with a limiting block, and the left side of the limiting block is in contact with the right side of the extrusion block. The first insulating shell and the second insulating shell can be connected by setting the limiting block to connect with the extrusion block.

[0010] Furthermore, the reset assembly includes a mounting ring and a torsion spring. The mounting ring is fixed to the left end of the surface of the second insulating shell, and the torsion spring is sleeved on the surface of the second insulating shell. The right end of the torsion spring is fixed to the left end of the rotating ring, and the left end of the torsion spring is fixed to the right end of the mounting ring. The rotating ring is supported by the reset assembly.

[0011] Furthermore, the fixing component includes an L-shaped hole, a support ring, a locking head, a pull rope, a first spring, and a locking hole. An L-shaped hole is formed on the circumferential surface of the rotating ring.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This quick docking device for the cable interface of imaging equipment with self-locking function has the following advantages:

[0018] 1. A stepped anti-loosening structure is constructed by using the mechanical interlocking of the limiting block and the pressing block as the first-level locking mechanism, combined with the elastic engagement of the locking head and the locking hole to form the second-level locking mechanism, and the third-level locking mechanism of the fastening component on the actuating ring. This design can effectively resist vibration and accidental pulling during equipment operation, and is particularly suitable for applications such as medical imaging equipment that have stringent requirements for connection stability, avoiding the problem of easy failure of single-point locking in traditional interfaces;

[0019] 2. The device effectively isolates external dust, liquid and other contaminants from entering the internal mechanical parts through the sealing structure formed by the rubber ring and the connecting ring.

By setting the rotating assembly 7, the user can rotate the toggle ring 71 to move the pull strap 43 during use. The movement of the pull strap 43 drives the pull rope 64 to move. The movement of the pull rope 64 drives the locking head 63 to move to the right and separate it from the locking hole 66 in the middle of the pressing block 22. After separation... Continue to rotate the toggle ring 71 to make the rotating ring 41 rotate. The rotation of the rotating ring 41 causes the limiting block 32 to flip forward and separate from the pressing block 22.

[0041] Wherein: a guide frame 11 is fixed on the circumferential surface of the fixed ring 21, and the extrusion head 85 is slidably connected inside the guide frame 11, and the extrusion head 85 is limited by the guide frame 11.

[0042] The working principle of the self-locking imaging equipment cable interface quick docking device provided by the present invention is as follows: When it is necessary to connect the first insulating shell 1 and the second insulating shell 14, the first connector 12 and the second connector 15 are aligned and inserted. At this time, the pressing block 22 on the fixing ring 21 will contact the limiting block 32 on the rotating ring 41. As the insertion action is completed, the restoring force of the torsion spring 52 will cause the rotating ring 41 to rotate, driving the limiting block 32 on the arc plate 31 to be inserted into the gap between the pressing block 22 and the rotating ring 21, thus achieving initial locking. At the same time, the locking head 63 in the fixing component 6 automatically inserts into the locking hole 66 of the pressing block 22 under the action of the first spring 65, forming a secondary lock. After the docking is completed, the locking plate 82 in the fastening component 8 pops up under the action of the elastic force of the second spring 84 and is inserted into the slot 83 of the actuating ring 71 to prevent the actuating ring 71 from rotating accidentally. This design can effectively ensure that the connection will not loosen under vibration or pulling conditions.

[0043] When disconnection is required, the user presses the snap plate 82 downwards through the squeezing head 85 to disengage it from the slot 83, thus unlocking it. Then, the user rotates the actuating ring 71 by the actuating plate 72. The rotation of the actuating ring 71 moves the pull strap 43, which pulls the pull rope 64, causing the snap head 63 to exit from the snap hole 66. Continuing to rotate the actuating ring 71 will cause the rotating ring 41 to rotate against the resistance of the torsion spring 52, causing the limiting block 32 to disengage from the gap between the squeezing block 22 and the rotating ring 21. At this point, the two first connectors 12 and the second connector 15 can be easily separated. During use, the rubber ring 9 and the connecting ring 10 form a sealing structure to protect the internal components such as the torsion spring 52 from environmental influences. The anti-slip design of the pull ring 17 facilitates operation and ensures smooth insertion and removal. The entire device achieves one-button operation through mechanical linkage, which not only ensures connection reliability but also simplifies the usage process.
