Description

Technical Field

[0001] This utility model specifically relates to a pin with a protective structure. Background Technology

[0002] Pins are used in electronic components to connect circuit boards, modules, or other electronic components. They are typically used to transmit signals, power, or data and play a crucial role in the assembly and maintenance of electronic equipment. Basic pin types include through-hole pins, surface mount pins, spring pins, and floating pins. Their materials are usually copper alloys or gold-plated, silver-plated, etc., to ensure good conductivity and corrosion resistance. The housing of the pin is usually made of plastic or ceramic materials to provide insulation protection and mechanical support.

[0003] Traditional pins are prone to bending or breaking during insertion and removal due to uneven force or improper operation. The contact surface between the pin and the socket may become poor due to wear or contamination, affecting signal transmission or power supply, and resulting in high maintenance costs later on.

[0004] Therefore, it is necessary to invent a pin with a protective structure to solve the above problems. Utility Model Content

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-5 The pin shown has a protective structure, including a pin body 1, a base 11 at the bottom of the pin body 1, a support 12 in the middle, and a protective component 2 fixed on the support 12.

[0029] Specifically, the protection component 2 includes a multi-stage sleeve 21, each of which has a telescopic hole 22 in the middle. The pin body 1 passes through the telescopic hole 22 and is provided with a capping component 23 at the top of the multi-stage sleeve 21. The capping component 23 covers the top of the pin body 1.

[0030] In this embodiment, the main body of the pin has a tapered top, which facilitates precise insertion into the target position.

[0031] The base 11 is located at the bottom of the pin body 1 and is used to fix the pin, ensuring its stability during use. The support base 12 is located in the middle of the pin body 1 and is used to fix the protection component 2. The protection component 2 includes a multi-stage sleeve 21, a capping component 23, etc., and is used to protect the pin body 1.

[0032] Reference Figure 5 The capping assembly 23 includes fixed plates 231 fixed on both sides of the top of the sleeve 21. Movable plates 232 are connected to the opposite sides of the fixed plates 231. A hinge 233 is provided between the movable plates 232 and the fixed plates 231, and the movable plates 232 on both sides can be opened in opposite directions.

[0033] Reference Figure 3-5 The multi-stage sleeve 21 has three stages. The bottom sleeve 21 has a telescopic cavity 24 inside. Limiting rings 25 are provided on both sides of the top opening of the telescopic cavity 24. The bottom of the multi-stage sleeve 21 has a retaining ring 26 extending outward. The upper retaining ring 26 matches the lower limiting ring 25. The capping assembly 23 is set on the top of the uppermost sleeve 21.

[0034] In this embodiment, the telescopic hole 22 is located in the middle of the multi-stage sleeve 21, and the pin body 1 passes through the telescopic hole 22 to ensure that the pin can freely extend and retract within the multi-stage sleeve 21. The telescopic cavity 24 is located inside the bottom sleeve 21 and is used to house the next-stage sleeve 21. The limiting rings 25 are located on both sides of the top opening of the telescopic cavity 24 to limit the extension and retraction range of the next-stage sleeve 21. The retaining ring 26 is located at the bottom of the multi-stage sleeve 21, and the upper-stage retaining ring 26 matches the lower-stage limiting ring 25 to ensure the stability of the sleeve 21 during extension and retraction.

[0035] Specifically, the dimensions of each lower-level sleeve 21 are smaller than those of the upper-level sleeve 21, and the internal space of the upper-level telescopic cavity 24 is at least sufficient to accommodate the lower-level sleeve 21.

[0036] Reference Figure 5 The sealing assembly 23 is set in two symmetrical groups. The connection between the fixed plate 231 and the movable plate 232 is provided with a hidden groove 234. A hinge 233 is installed inside the hidden groove 234. The top of the hinge 233 does not exceed the top of the hidden groove 234. A magnetic groove 235 is provided in the middle of one side of the movable plate 232, and a corresponding magnetic block 236 is provided on the opposite side of the movable plate 232.

[0037] Specifically, the magnetic groove 235 is located on one side of the movable plate 232, and its bottom does not contact the bottom of the movable plate 232. The size of the magnetic groove 235 matches the size of the magnetic block 236.

[0038] In this embodiment, the fixed plate 231 is fixed to both sides of the top of the sleeve 21 and is used to connect the movable plate 232. The movable plate 232 is connected to the fixed plate 231 via a hinge 233 and can be opened in the opposite direction to protect the top of the pin body 1. The hinge 233 is installed in the hidden groove 234 to ensure that the hinge 233 is not exposed, improving aesthetics and durability. The magnetic groove 235 and the magnetic block 236 are located on one side of the movable plate 232 and are used to automatically attract when the capping assembly 23 is closed to ensure the tightness of the cap.

[0039] Reference Figure 2 The top of the pin body 1 is conical, and the apex of the cone is between the two movable plates 232.

[0040] In this embodiment, the pin is removed from its retracted state, and the multi-stage sleeve 21 unfolds step by step, allowing the pin body 1 to extend from the telescopic hole 22 until it is fully unfolded. The top of the pin body 1 is aligned with the target position and inserted for use. After use, the pin body 1 is retracted into the multi-stage sleeve 21, and the sleeve 21 is compressed step by step until the pin is fully retracted. The movable plate 232 is opened in the opposite direction, fully exposing the top of the pin body 1. The movable plate 232 is then closed, and the magnetic groove 235 and magnetic block 236 automatically attract each other, ensuring the sealing assembly 23 is tightly closed.

[0041] In this embodiment, when the pin is not in use, the multi-stage sleeve 21 can effectively protect the pin body 1 from external impacts or contamination, and extend the service life of the pin.

[0042] Specifically, when storing the pins, the capping assembly 23 can completely seal the top of the pin body 1 to prevent dust, moisture, etc. from entering, ensuring the cleanliness and functional integrity of the pins.

[0043] Specifically, the size design of the multi-stage sleeve 21 allows the upper-stage sleeve 21 to completely accommodate the lower-stage sleeve 21, facilitating the carrying and storage of the pins and saving space.

[0044] Specifically, the telescopic structure of the sleeve 21 allows the pin to be quickly extended during use and quickly retracted after use, making it easy to operate.

[0045] In this embodiment, the top of the pin body 1 is tapered, which makes it easier to align with the target position during insertion, thus improving the accuracy and efficiency of use.

[0046] Specifically, the magnetic groove 235 and magnetic block 236 design of the capping assembly 23 enable the capping assembly 23 to automatically attach when closed, ensuring that the top of the pin is completely sealed, making the operation simple and reliable.

[0047] In this embodiment, the hinge 233 is installed in the hidden groove 234, and the top of the hinge 233 does not exceed the top of the hidden groove 234, which improves the overall aesthetics and avoids the hinge 233 from being interfered with or damaged by external factors during use.

[0048] Specifically, the capping assembly 23 is set in two symmetrical groups, which makes the pins subjected to uniform force when closed, ensuring the stability and sealing of the capping assembly 23, and further enhancing the protection effect of the pins.

[0049] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
