Description

Technical Field

[0001] This utility model belongs to the field of plug technology, specifically a waterproof plug. Background Technology

[0002] In existing lighting fixture connections or electrical equipment connections, the plug is a key component for achieving electrical conductivity. However, traditional plugs mostly connect directly to lighting fixtures or other equipment, lacking effective waterproof components, resulting in poor waterproof performance. In humid environments or when used outdoors, the plug is prone to water leakage, which can lead to short circuits, electrical leaks, and other safety hazards, seriously affecting the lifespan and safety of the equipment. Therefore, developing a plug with excellent waterproof performance is particularly important. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a waterproof plug, which effectively solves the problems mentioned in the background.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a waterproof plug, comprising a plug body, wherein a sealing element is sleeved on the outside of the plug body;

[0005] The sealing element includes a sealing sleeve, with an inner sealing ring connected to the inner wall of the sealing sleeve and an outer sealing ring connected to the outer wall of the sealing sleeve.

[0006] Preferably, the outer wall of the plug body is provided with an installation ring groove, the sealing sleeve is fitted on the outer wall of the plug body, and the inner sealing ring is fitted into the installation ring groove.

[0007] Preferably, the seal is made of silicone.

[0008] Preferably, the plug body has symmetrical through-holes for inserting pins, and a conductive sleeve is embedded inside the pin holes.

[0009] Preferably, a guide groove is provided at the end of the pin hole.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model effectively prevents moisture from seeping into the plug from the outside by covering the plug body with a sealing element and adopting a double sealing structure of inner and outer sealing rings, which significantly improves the waterproof performance of the plug and enables it to be used safely in humid environments or outdoors.

[0012] 2. This new type of sealant uses silicone material, which not only has good waterproof performance, but also excellent elasticity and weather resistance. It can maintain a stable sealing effect under various complex environmental conditions and extend the service life of the plug.

[0013] 3. The conductive sleeve embedded inside the new type of pin hole and the guide groove design at the end not only ensure the conductivity of the plug, but also improve the service life and ease of use of the plug, so that the plug can achieve efficient and stable electrical connection while meeting waterproof requirements.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example 1, by Figures 1-5 As shown, this utility model includes a plug body 1, and a sealing member 2 is sleeved on the outside of the plug body 1;

[0024] The sealing element 2 includes a sealing sleeve 201, with an inner sealing ring 202 connected to the inner wall of the sealing sleeve 201 and an outer sealing ring 203 connected to the outer wall of the sealing sleeve 201.

[0025] The outer wall of the plug body 1 is provided with an installation ring groove 3, the sealing sleeve 201 is fitted on the outer wall of the plug body 1, and the inner sealing ring 202 is fitted into the installation ring groove 3.

[0026] The seal 2 is made of silicone, which has excellent elasticity, resistance to high and low temperatures, and good aging resistance.

[0027] The plug body 1 has symmetrical through-holes 4, and a conductive sleeve 5 is embedded inside the through-holes 4.

[0028] The end of the pin hole 4 is provided with a guide groove 6, which facilitates the quick alignment and positioning of the pin during docking.

[0029] Working principle:

[0030] When in use, the plug body 1 is inserted into the corresponding socket. The pins on the socket correspond to the pin holes 4 on the plug body 1, so that the pins contact the conductive sleeve 5 inside the pin holes 4 to achieve conductivity. The sealing element 2 fits tightly against the inner wall of the socket. The inner sealing ring 202 is embedded in the mounting ring groove 3, and the outer sealing ring 203 is in close contact with the inner wall of the socket, forming a double sealing structure to effectively prevent moisture from seeping into the plug from the outside. The conductive sleeve 5 inside the pin holes 4 ensures stable current transmission, and the guide groove 6 facilitates the insertion and alignment of the pins, reduces wear during insertion and removal, and improves the service life and ease of use of the plug.

[0031] Preferably, the plug body 1 of this device can be either a double-ended structure or a single-ended structure (e.g., Figure 5 ).
