Abstract

This utility model provides a plug-socket connection structure, including a plug and a socket. The plug is hollow inside with an opening at the bottom and contains a main conductive contact plate. An elastic sleeve is fitted on the lower outer wall of the plug, with the outer wall of the elastic sleeve slightly protruding relative to the outer wall of the plug. The socket is hollow inside with an opening at the top and contains a secondary conductive contact plate. When the plug is inserted into the socket, the outer wall of the elastic sleeve fitted on the lower outer wall of the plug is press-fitted with the inner wall of the socket, and the main conductive contact plate inside the plug contacts the secondary conductive contact plate inside the socket. When the lower part of the plug is inserted into the socket, the press-fit of the elastic sleeve on the lower outer wall of the plug with the inner wall of the socket seals the gap between the plug and the socket, preventing dust and liquid from entering through the gap, thus effectively achieving dustproof and waterproof effects.

[0001] This utility model relates to the field of plug and socket structure technology, and in particular to a plug-and-socket connection structure. Background Technology

[0002] Plugs and sockets are essential components in electrical connections, used to connect electrical appliances to a power source. A plug is a device that is inserted into a socket to connect to a power source; it typically contains one or more conductive contacts for transmitting current. A socket, on the other hand, is a device fixed to a wall or other location to receive the plug and provide power. The combined use of plugs and sockets allows various electrical devices to be safely and conveniently connected to a power source.

[0003] Currently, when a plug is inserted into a socket, there is a gap at the point of contact between the plug and the socket. When the plug and socket are used outdoors, dust and liquid can easily enter through this gap, which can pose a risk of damage to the plug and socket. Therefore, the existing plug and socket connection structure is not very safe. Utility Model Content

[0006] In some embodiments, a ring groove is provided on the lower outer wall of the plug, and the elastic sleeve is fitted in the ring groove.

[0007] In some embodiments, the outer wall of the elastic sleeve protrudes 0.2-1 mm relative to the outer wall of the plug.

[0008] In some embodiments, a space is formed between the inner wall of the plug and the outer wall of the main conductive contact plate; a ring plate is provided in the inner center of the socket, a first receiving groove is formed between the inner wall of the socket and the outer wall of the ring plate, a second receiving groove is formed between the inner bottom wall of the socket and the inner wall of the ring plate, and the secondary conductive contact plate is disposed in the second receiving groove.

[0009] In some embodiments, the elastic sleeve is made of silicone or rubber.

[0010] In some embodiments, the plug is made of PC plastic.

[0011] In some embodiments, the socket is made of PC plastic.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, when the plug is inserted into the socket, the lower end of the plug is inserted into the interior of the socket. At this time, the main conductive contact plate inside the plug makes electrical contact with the secondary conductive contact plate inside the socket, thus achieving electrical connection between the plug and the socket.

[0022] This utility model provides the following technical solution: a plug and socket connection structure 100, including a plug 10 and a socket 20; the plug 10 is hollow inside and has an opening at the bottom, and has a main conductive contact plate 101 inside, and has an elastic sleeve 104 fitted on the lower outer wall of the plug 10, the outer wall of the elastic sleeve 104 being slightly protruding relative to the outer wall of the plug 10; the socket 20 is hollow inside and has an opening at the top, and has a secondary conductive contact plate 204 inside; when the plug 10 is inserted into the socket 20, the outer wall of the elastic sleeve 104 fitted on the lower outer wall of the plug 10 is interference-fitted with the inner wall of the socket 20, and the main conductive contact plate 101 inside the plug 10 is in contact with the secondary conductive contact plate 204 inside the socket 20.

[0023] In the plug-socket connection structure 100 provided in this embodiment, when the plug 10 is plugged into the socket 20, the lower end of the plug 10 can be inserted into the interior of the socket 20. At this time, the main conductive contact plate 101 inside the plug 10 and the secondary conductive contact plate 204 inside the socket 20 make electrical contact to achieve electrical connection between the plug 10 and the socket 20. Furthermore, when the lower end of the plug 10 is inserted into the interior of the socket 20, the outer wall of the elastic sleeve 104 fitted on the outer wall of the lower end of the plug 10 is interference-fitted with the inner wall of the socket 20 to seal the gap between the plug 10 and the socket 20, thereby preventing dust and liquid from entering through the gap between the plug 10 and the socket 20. This effectively achieves a dustproof and waterproof effect, offering practical and efficient advantages.

[0024] In some embodiments, a ring groove 103 is provided on the lower outer wall of the plug 10, and the elastic sleeve 104 is fitted in the ring groove 103. Specifically, the ring groove 103 on the lower outer wall of the plug 10 is used to allow the elastic sleeve 104 to be fitted in, and the ring groove 103 is also used to limit the elastic sleeve 104, so as to securely install the elastic sleeve 104 on the side wall of the lower end of the plug 10.

[0025] In some embodiments, the outer wall of the elastic sleeve 104 protrudes 0.2-1 mm relative to the outer wall of the plug 10. Specifically, the outer wall of the elastic sleeve 104 preferably protrudes 0.3 mm relative to the outer wall of the plug 10, so that when the lower end of the plug 10 is inserted into the socket 20, the outer wall of the elastic sleeve 104, which protrudes 0.3 mm relative to the outer wall of the plug 10, can be squeezed against the inner wall of the socket 20, so that the outer wall of the elastic sleeve 104 fitted on the lower side wall of the plug 10 and the inner wall of the socket 20 achieve an interference fit, thereby sealing the gap where the plug 10 and the socket 20 are inserted.

[0026] In some embodiments, a space 102 is formed between the inner wall of the plug 10 and the outer wall of the main conductive contact plate 101; a ring plate 201 is provided in the inner center of the socket 20, a first receiving groove 202 is formed between the inner wall of the socket 20 and the outer wall of the ring plate 201, a second receiving groove 203 is formed between the inner bottom wall of the socket 20 and the inner wall of the ring plate 201, and the secondary conductive contact plate 204 is disposed in the second receiving groove 203. Specifically, when the lower end of the plug 10 is inserted into the socket 20, the first receiving groove 202 inside the socket 20 accommodates the side wall of the plug 10, and simultaneously the elastic sleeve 104 fitted on the outer wall of the lower end of the plug 10 is accommodated in the first receiving groove 202 of the socket 20, so that the outer wall of the elastic sleeve 104 contacts the inner wall of the socket 20 for an interference fit; the second receiving groove 203 inside the socket 20 has a secondary conductive contact 204, and the second receiving groove 203 inside the socket 20 is also used to accommodate the main conductive contact 101 inside the plug 10, so that the secondary conductive contact 204 in the second receiving groove 203 inside the socket 20 can make electrical contact with the main conductive contact 101 inside the plug 10; and a ring plate 201 provided in the middle of the socket 20 is accommodated by a ring space 102 inside the plug 10. Thus, the plug 10 is effectively inserted into the socket 20.

[0027] In some embodiments, the elastic sleeve 104 is made of silicone or rubber.

[0028] In some embodiments, the plug 10 is made of PC plastic.

[0029] In some embodiments, the socket 20 is made of PC plastic.
