DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes. Example

[0022] Please refer to Figures 1 to 6. In this embodiment, a dust-proof connecting terminal assembly is provided, including a terminal body 1. A protective mechanism 2 is sleeved on the terminal body 1. After two terminals are plugged in, the protective mechanism 2 can seal and protect the connection between the two terminals, thereby achieving a dust-proof effect. The terminal body 1 includes a terminal head 11. One end of the terminal head 11 is connected to a cable 12, and a protective cover 13 is further provided at the connection between the cable 12 and the terminal head 11. The protective cover 13 can prevent the connection between the cable 12 and the terminal head 11 from being excessively bent, thereby protecting the cable 12 and making the connection more stable.

[0023] The terminal head 11 is provided with a protective mechanism 2, which can protect the connection between the two terminals after they are plugged in, preventing external dust from entering the inside, and the protective mechanism 2 also has a limiting effect, so that the two terminals are prevented from accidentally touching and separating after being plugged in, thereby increasing the safety of use;

[0024] The protection mechanism 2 includes a protection sleeve 21, which is a cylindrical structure with a hollow interior. The left and right ends of the protection sleeve 21 are connected to protective covers 22, which are threadedly connected to the protection sleeve 21. At the same time, a limiter 23 is provided on the upper part of the protection sleeve 21. The limiter 23 can fasten the terminal head 11 to prevent it from moving, thereby playing a limiting role, thereby avoiding the risk of accidental separation and disconnection. The detachable protective cover 22 can be replaced with different protective covers 22 according to the size of different terminal heads 11, thereby increasing its adaptability.

[0025] The front and rear sides of the protective sleeve 21 are provided with heat dissipation holes 211, and dustproof nets 212 are installed in the heat dissipation holes 211. The heat dissipation holes 211 can prevent the problem of poor heat dissipation after the protective sleeve 21 covers the terminal head 11. At the same time, the dustproof net 212 prevents the entry of external dust. The left and right sides of the protective sleeve 21 are provided with thread grooves 213. The protective sleeve 21 is threadedly connected to the protective cover 22 through the thread grooves 213, and a thread ring 221 is provided on the protective cover 22 corresponding to the thread groove 213. The thread ring 221 is adapted to the thread groove 213, and then through the setting of the thread ring 221 and the thread groove 213, a thread connection is realized between the two, which is convenient for replacing the protective cover 22. In order to facilitate its disassembly, a protrusion 222 is also provided on the side wall of the protective cover 22. The protrusion 222 can play a role of anti-slip and convenient for force;

[0026] The purpose of the protective cover 22 is to use different protective covers 22 according to the terminal heads 11 with different outer diameters. The protective cover 22 is provided with an inner hole 223. The inner holes 223 of different sizes are suitable for different terminal heads 11. The inner hole 223 is provided with a rubber ring 224. The rubber ring 224 is elastic, so that it can be sleeved on the terminal head 11 and sealed therewith.

[0027] The upper side wall of the protective sleeve 21 is provided with a through hole 214, and the limiting member 23 is slidably connected in the through hole 214. The limiting member 23 includes a connecting rod 231, and two sliding rods 232 are provided at the lower end of the connecting rod 231. The two sliding rods 232 are respectively located in the two through holes 214 and slidably connected thereto, and a bottom plate 233 is provided at the bottom of each sliding rod 232. A spring 234 is also provided on the sliding rod 232 between the connecting rod 231 and the protective sleeve 21;

[0028] Specifically, first select a suitable protective cover 22 according to different terminal heads 11, then install it on the protective cover 21, and then put the protective cover 22 on the terminal head 11. During the installation process, pull the connecting rod 231 to move it upward, so that the bottom plate 233 will not contact the terminal, move the protective mechanism 2 to the side of the cable 12, and expose the end of its terminal head 11, so that another terminal can be connected to it. After the connection is completed, move the protective mechanism 2 in the opposite direction so that the protective cover 21 can cover the connection of the terminal, and at the same time release the connecting rod 231. Under the pull of the spring 234, the bottom plate 233 contacts the terminal and presses it to achieve limit.

[0029] In the utility model, the connection between the two terminals is covered by a protective mechanism 2, so that dust will not enter the gap of the connection when the terminals are used for a long time, thereby avoiding the influence of dust on the connectivity of the terminals. At the same time, the protective mechanism 2 can also limit the terminals to avoid disconnection due to accidental contact.

[0030] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
