Description

Technical Field

[0001] This utility model relates to the field of PIN connector technology, and more specifically to a waterproof fixing device for multi-PIN connectors. Background Technology

[0002] Connectors are primarily used for signal conduction and connection. They are widely used in computer accessories, industrial equipment, and digital products. Some connectors have contacts in the form of pins, which are metallic materials used in connectors to conduct electricity (signals).

[0003] Most existing multi-pin connectors rely on silicone pads for waterproof sealing. To prevent oxidation of the silicone pads, their condition needs to be checked and maintained regularly. Since the silicone pads are inside the connector, tools are needed to disassemble the connector for inspection and maintenance, which is inconvenient. Utility Model Content

[0004] To address this issue, this utility model provides a waterproof fixing device for multi-PIN connectors. By using a fixing device, a connecting device, and a PIN waterproof silicone pad, it solves the problem that the silicone pad is located inside the connector, requiring tools to disassemble the connector for inspection and maintenance, which is inconvenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof fixing device for multi-PIN connectors, comprising a PIN connector device, a fixing device on one side of the PIN connector device, two connecting devices between the PIN connector device and the fixing device, the PIN connector device including a PIN connecting plate, a connecting frame fixedly provided on one side of the PIN connecting plate, a connecting hole opened inside the PIN connecting plate, the fixing device including a fixing plate, an auxiliary connecting hole opened inside the fixing plate, a PIN waterproof silicone pad embedded inside the connecting frame, the connecting device including a fixing frame unit and an installation frame unit, the fixing frame unit including a fixing frame, through holes opened on both sides of the fixing frame, a rotating shaft provided inside the fixing frame, a gear fixedly sleeved on the outside of the rotating shaft, two fixing components provided outside the gear, the fixing components including a toothed plate, a spring and a connecting plate respectively fixedly provided at both ends of the toothed plate, a trapezoidal block fixedly provided on one side of the connecting plate, and the installation frame unit including an installation frame, with installation holes opened at both ends of the installation frame.

[0006] Preferably, the fixing frame is embedded inside the mounting frame and slidably connected to the mounting frame, the fixing frame is fixedly connected to the PIN connecting plate, and the mounting frame is fixedly connected to the fixing plate.

[0007] Preferably, one end of the rotating shaft is connected to one side wall of the fixed frame via a bearing, and the other end of the rotating shaft is connected to the PIN connecting plate via a bearing.

[0008] Preferably, the toothed plate is disposed inside the fixed frame and slidably connected to the fixed frame, and the toothed plate is slidably connected to the gear.

[0009] Preferably, one end of the spring is fixedly connected to the toothed plate, and the other end of the spring is fixedly connected to another connecting plate.

[0010] Preferably, the connecting plate is disposed inside the fixed frame and is slidably connected to the fixed frame.

[0011] Preferably, one end of the trapezoidal block passes through the through hole and is slidably connected to the through hole, and the other end of the trapezoidal block extends into the mounting hole and is slidably connected to the mounting hole.

[0012] The present invention has the following advantages:

[0013] 1. By pushing a trapezoidal block into the through hole, the movement of the trapezoidal block causes the toothed plate to move through the connecting plate, which in turn causes the toothed plates on both sides to move synchronously through the gear. The movement of the toothed plates causes the spring to contract, thereby allowing the trapezoidal block to be pulled into the through hole from the mounting hole, releasing the connection between the fixing frame and the mounting frame, thus facilitating the separation of the fixing plate from the connecting frame, thereby exposing the PIN waterproof silicone pad, which is convenient for subsequent inspection and maintenance of the PIN waterproof silicone pad;

[0014] 2. Simply align the mounting frame with the fixing frame and snap it on. When snapped on, the edge of the mounting frame contacts the inclined side of the trapezoidal block, thus synchronizing the above operations. When the mounting hole moves to align with the trapezoidal block, the contracted spring causes the toothed plate to return to its original position through elasticity, thereby allowing the trapezoidal block to be inserted into the mounting hole, completing the connection between the fixing frame unit and the mounting frame unit, and thus completing the connection between the PIN connector device and the fixing device for subsequent use.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] See attached document Figure 1 -Appendix Figure 5The present invention provides a waterproof fixing device for multi-PIN connectors, comprising a PIN connector device 1, a fixing device 2 on one side of the PIN connector device 1, and two connecting devices 3 between the PIN connector device 1 and the fixing device 2. The PIN connector device 1 includes a PIN connecting plate 11, a connecting frame 12 fixedly mounted on one side of the PIN connecting plate 11, and a connecting hole 13 inside the PIN connecting plate 11. The fixing device 2 includes a fixing plate 21, an auxiliary connecting hole 22 inside the fixing plate 21, and a PIN waterproof silicone pad 4 embedded inside the connecting frame 12. 3 includes a fixed frame unit 31 and a mounting frame unit 32. The fixed frame unit 31 includes a fixed frame 311, with through holes 312 on both sides. The fixed frame 311 has a rotating shaft 313 inside, and a gear 314 is fixedly sleeved on the outside of the rotating shaft 313. The gear 314 has two fixing components on the outside. The fixing components include a toothed plate 315. A spring 316 and a connecting plate 317 are fixedly fixed at both ends of the toothed plate 315, and a trapezoidal block 318 is fixedly fixed on one side of the connecting plate 317. The mounting frame unit 32 includes a mounting frame 321, with mounting holes 322 on both ends.

[0025] In this embodiment, to facilitate the inspection and maintenance of the PIN waterproof silicone pad 4, a trapezoidal block 318 is pushed into the through hole 312. The movement of the trapezoidal block 318 causes the toothed plate 315 to move via the connecting plate 317, and then the gear 314 causes the two toothed plates 315 to move synchronously. The movement of the toothed plates 315 causes the spring 316 to contract, thereby allowing the trapezoidal block 318 to be retracted from the mounting hole 322 into the through hole 312, releasing the connection between the fixing frame 311 and the mounting frame 321, thus facilitating the separation of the fixing plate 21 from the connecting frame 12, thereby exposing the PIN waterproof silicone pad 4 for subsequent inspection and maintenance.

[0026] In order to facilitate the fitting of the fixing plate 21 and the connecting frame 12, the device adopts the following technical solution: the fixing frame 311 is embedded in the mounting frame 321 and slidably connected to the mounting frame 321. The fixing frame 311 is fixedly connected to the PIN connecting plate 11. The mounting frame 321 is fixedly connected to the fixing plate 21. The mounting frame 321 can be fitted outside the fixing frame 311, so that the mounting frame 321 can only slide along the fixing frame 311. Thus, after the mounting frame unit 32 is connected to the mounting frame unit 32, the fixing plate 21 will not detach from the connecting frame 12, ensuring the normal operation of the PIN waterproof silicone pad 4. The PIN waterproof silicone pad 4 is a silicone pad that is symmetrically formed at both ends and has a very thin membrane reserved in the middle, which is easy to puncture when multiple PINs are fitted. After the PIN needle punctures the membrane, the multiple PIN needles will tightly fit with the connector, playing a waterproof role. It fixes the PIN to prevent loosening and deformation. In addition, when the female socket is plugged in, the silicone acts as a rebound to hold the inner wall of the female socket.

[0027] To facilitate the connection between the fixed frame unit 31 and the mounting frame unit 32, the device employs the following technical solution: one end of the rotating shaft 313 is connected to one side wall of the fixed frame 311 via a bearing, and the other end of the rotating shaft 313 is connected to the PIN connecting plate 11 via a bearing; the toothed plate 315 is located inside the fixed frame 311 and slidably connected to the fixed frame 311; the toothed plate 315 is slidably connected to the gear 314; one end of the spring 316 is fixedly connected to the toothed plate 315; the other end of the spring 316 is fixedly connected to another connecting plate 317; the connecting plate 317 is located inside the fixed frame 311 and slidably connected to the fixed frame 311; and one end of the trapezoidal block 318... The through hole 312 is slidably connected to the through hole 312. One end of the trapezoidal block 318 extends into the mounting hole 322 and is slidably connected to the mounting hole 322. The mounting frame 321 is aligned with the fixing frame 311 and fastened. When fastened, the edge of the mounting frame 321 contacts the inclined side of the trapezoidal block 318, thus synchronizing the above operations. When the mounting hole 322 moves to align with the trapezoidal block 318, the retracted spring 316 causes the toothed plate 315 to return to its original position through elastic force, thereby allowing the trapezoidal block 318 to be inserted into the mounting hole 322, completing the connection between the fixing frame unit 31 and the mounting frame unit 32, and thus completing the connection between the PIN connector device 1 and the fixing device 2 for subsequent use.

[0028] The usage process of this utility model is as follows: When using this utility model, the PIN connector device 1 is connected to the connector device. When it is necessary to expose the PIN waterproof silicone pad 4 for inspection and maintenance, taking one set of connecting devices 3 as an example, by pushing a trapezoidal block 318 into the through hole 312, the movement of the trapezoidal block 318 causes the toothed plate 315 to move through the connecting plate 317, and then the gear 314 causes the toothed plates 315 on both sides to move synchronously. The movement of the toothed plates 315 causes the spring 316 to contract, thereby causing the trapezoidal block 318 to be retracted from the mounting hole 322 into the through hole 312, and the connection between the fixing frame 311 and the mounting frame 321 is released. This facilitates the separation of the fixing plate 21 from the connecting frame 12, thereby exposing the PIN waterproof silicone pad 4 for subsequent inspection and maintenance. Similarly, during installation, the mounting frame 321 is aligned with the fixing frame 311 and snapped on. When snapped on, the edge of the mounting frame 321 contacts the inclined side of the trapezoidal block 318, thus synchronizing the above operations. When the mounting hole 322 moves to align with the trapezoidal block 318, the retracted spring 316 uses its elasticity to reset the toothed plate 315, thereby allowing the trapezoidal block 318 to be inserted into the mounting hole 322, completing the connection between the fixing frame unit 31 and the mounting frame unit 32, and thus completing the connection between the PIN connector device 1 and the fixing device 2 for subsequent use.

[0029] The above are merely preferred embodiments of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
