Description

Technical Field

[0001] The utility model relates to the technical field of input terminal protection, in particular to a dust-proof mechanism for input terminals. Background Art

[0002] The input terminal is the interface for a liquid crystal TV to receive signals, usually including standard video input AV terminals, DV input terminals, S-video input terminals, video color difference input terminals, VGA input terminals, etc. Through these input terminals, it is convenient to connect with other supporting devices.

[0003] The existing input terminals do not have a dust-proof structure. Dust entering will affect the normal connection of the wiring. Secondly, most of the existing dust-proof structures use matching plastic covers for covering, but the existing plastic covers are easy to lose after being disassembled, resulting in inability to be used again, thus having a certain impact. Therefore, a dust-proof mechanism for input terminals is urgently needed to solve the above problems. Content of the Utility Model

[0004] To solve the above problems, the utility model provides a dust-proof mechanism for input terminals, and the utility model is realized through the following technical solutions.

[0005] A dust-proof mechanism for input terminals includes a terminal wiring box, and an opening is provided on the front side of the terminal wiring box. It further includes a terminal positioning seat. A terminal through-hole is provided on the outer surface of the terminal positioning seat. Two L-shaped closing plates movably connected to the terminal positioning seat cover the position of the terminal through-hole. A U-shaped sealing gasket is fixedly connected to the top of the L-shaped closing plate, and an L-shaped sealing strip is fixedly connected to one side of the L-shaped closing plate. A loop-shaped sealing gasket is fixedly connected to the bottom of the terminal positioning seat.

[0006] Furthermore, two sliding rods are fixedly connected to the bottom of the terminal positioning seat, and the L-shaped closing plate is movably connected to the sliding rods through sliding holes provided.

[0007] Furthermore, springs are fixedly connected to both ends of the sliding rods, and one end of the spring is fixedly connected to the L-shaped closing plate.

[0008] Furthermore, a push plate is fixedly connected to one end of the top of the L-shaped closing plate. The push plate passes through the terminal through-hole and is movably connected to the terminal positioning seat, and a 90° angle is formed between the two push plates.

[0009] Furthermore, when the two L-shaped closing plates are closed and docked, at this time, the U-shaped sealing gasket is fitted and docked on the outer side of the loop-shaped sealing gasket.

[0010] Further, screw holes are provided on the outer surfaces of the terminal junction box and the terminal positioning seat, and screws are penetratingly connected inside the screw holes. The terminal junction box is fixedly connected to the terminal positioning seat through the screws, and the terminal positioning seat covers the opening.

[0011] The beneficial effect of the present utility model is that during the operation of the device, the input end can be squeezed into the opening connected to the terminal positioning seat through the middle of the two push plates, so as to be docked with the wiring terminal inside the terminal junction box. Among them, the two L-shaped closing plates automatically close without external force. At the same time, the L-shaped closing plates are hermetically closed with the circular sealing gasket on the terminal positioning seat through the U-shaped sealing gasket. At the same time, the two L-shaped closing plates are hermetically closed through the L-shaped sealing strip provided therebetween, so that the L-shaped closing plates can be hermetically covered on the terminal positioning seat, and then dust can be prevented from entering the terminal junction box.

Two L-shaped closing plates 3 movably connected to the terminal positioning seat 2 cover the position of the terminal through-hole 21. A U-shaped sealing pad 34 is fixedly connected to the top of the L-shaped closing plate 3. An L-shaped sealing strip 33 is fixedly connected to one side of the L-shaped closing plate 3. A U-shaped sealing pad 22 is fixedly connected to the bottom of the terminal positioning seat 2.

[0026] By adopting the above technical solution, when using the device, the input end can be squeezed into the opening 11 connected to the terminal positioning seat 2 through the middle of the two push plates 31, so as to be connected to the wiring terminal inside the terminal connection box 1. Among them, the two L-shaped closing plates 3 automatically close without external force. At the same time, the L-shaped closing plate 3 is hermetically closed with the U-shaped sealing pad 22 on the terminal positioning seat 2 through the U-shaped sealing pad 34. At the same time, the two L-shaped closing plates 3 are hermetically closed through the provided L-shaped sealing strip 33 between them, so that the L-shaped closing plate 3 can be hermetically covered on the terminal positioning seat 2, and then dust can be prevented from entering the inside of the terminal connection box 1.

At the same time, the spring 4 fixed on the slide bar 23 is connected to the L-shaped closing plate 3. When the two push plates 31 are pushed to drive the two L-shaped closing plates 3 to move and open on the slide bar 23, at this time, the L-shaped closing plate 3 can squeeze the connected spring 4. After being pressed, the slide bar 23 can automatically reset under the action of no external force, so that the L-shaped closing plate 3 on the terminal positioning seat 2 can automatically close.

[0031] Specifically, when the two L-shaped closing plates 3 are closed and docked, at this time, the U-shaped gasket 34 fits and docks on the outer side of the loop gasket 22.

[0032] By adopting the above technical solution, the provided U-shaped gasket 34 can fit on the loop gasket 22 for sealing cooperation, so that the two closed L-shaped closing plates 3 can be hermetically connected to the terminal positioning seat 2.
