Abstract

This utility model discloses a waterproof cable connector sealing structure, including a socket, a plug, and a connecting assembly. The socket has a connector, and the plug has a socket. The connector is inserted into the socket, and the connecting assembly connects the socket and the plug together. An elastic sealing element is fitted onto the connector and is located between adjacent end faces of the plug and the socket. The elastic sealing element is pressed and sealed by the connecting force of the connecting assembly. A protruding pressing portion is provided on the end face of the plug that contacts the elastic sealing element. The pressing portion presses the elastic sealing element, causing it to elastically deform and embed into the elastic sealing element. When the plug and socket are inserted, the pressing portion at the socket opening of the plug embeds into the elastic sealing element, making the elastic sealing element more tightly pressed and increasing the contact area between the socket end face and the elastic sealing element, resulting in a better sealing effect.

Description

Technical Field

[0001] This utility model belongs to the field of waterproof connector technology, and in particular relates to a waterproof line connector sealing structure. Background Technology

[0002] In numerous fields such as outdoor equipment, industrial electrical appliances, and new energy, waterproof connection structures (such as sockets and plugs) play a crucial role. The working environments in these fields are often complex, placing stringent requirements on electrical connection structures. The most critical requirement is to ensure high reliability while effectively preventing the intrusion of external media such as moisture and dust into the connection structure. Once moisture or dust intrudes, it can not only cause short circuits or open circuits in the electrical connections, affecting the normal operation of the equipment, but also damage internal electronic components, shorten the equipment's lifespan, and even lead to safety accidents.

[0003] To meet the aforementioned waterproofing requirements, traditional waterproof connection structures generally employ a static sealing method using sealing rings. The working principle involves applying pressure to the sealing ring after the socket and plug are connected, using an external threaded or snap-fit ​​structure. This causes the sealing ring to elastically deform, filling the gap between the socket and plug, thus achieving waterproofing.

[0004] However, this traditional structure, which relies solely on sealing rings to fill gaps for waterproofing, has revealed numerous shortcomings in practical applications, resulting in less than ideal waterproofing performance. Firstly, over long-term use, the elasticity of the sealing ring gradually decreases due to environmental factors (such as temperature changes and UV radiation), leading to a decline in sealing performance and an inability to continuously and effectively fill gaps, allowing moisture and dust to penetrate. Secondly, when the socket and plug are connected, it is difficult to ensure a completely uniform gap, and the degree of compression of the sealing ring varies at different locations, easily causing localized incomplete sealing and further weakening the waterproofing effect. Furthermore, when the connection structure is subjected to external forces (such as vibration or impact), a slight relative displacement may occur between the socket and plug, causing the gaps originally filled by the sealing ring to reappear, leading to waterproofing failure. Utility Model Content

[0021] Because of the adoption of the above technical solution, this utility model has the following advantages and positive effects compared with the prior art:

[0022] 1. When the plug and socket of this utility model are inserted together, the pressing part at the opening of the plug hole is embedded in the elastic seal, which makes the elastic seal more tightly pressed and increases the contact area between the end face of the plug hole and the elastic seal, resulting in a better sealing effect.

[0023] 2.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise ratios, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0037] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0038] See Figures 1 to 5 The core of this utility model is to provide a waterproof line connector sealing structure, including a socket 1, a plug 2 and a connecting component. The socket 1 is provided with a connector 3, the plug 2 is provided with a socket hole, the connector 3 is inserted into the socket hole, and the connecting component connects the socket 1 and the plug 2 together.

[0039] The connector 3 is fitted with an elastic seal, which is located between the adjacent end faces of the plug 2 and the socket 1. The elastic seal is pressed and sealed by the connecting force of the connecting components.

[0040] The end face of plug 2 that contacts the elastic seal has a protruding compression part. The compression part compresses the elastic seal, causing it to deform elastically and embed itself into the elastic seal. The embedding of the compression part into the elastic seal makes the elastic seal more tightly pressed and increases the contact area between the end face of the plug and the elastic seal, resulting in a better sealing effect.

[0041] In this embodiment, the compression part is an annular protrusion 5, and the elastic seal is a first sealing ring 4. The width of the annular protrusion 5 gradually decreases in the direction away from the insertion hole. It is easy to understand that with the same force, the volume of the annular protrusion 5 compressing and embedding into the first sealing ring 4 is constant. Because the annular protrusion 5 gradually decreases in width in the direction away from the insertion hole, the depth of embedding of the protrusion into the first sealing ring 4 is increased, resulting in a better sealing effect.

[0042] The end face of the socket 1 that contacts the first sealing ring 4 has at least one annular groove. The end face of the first sealing ring 4 facing the socket 1 has a corresponding annular elastic protrusion 6, which is integrally formed with the first sealing ring 4. The annular elastic protrusion 6 is embedded in the annular groove. When the annular protrusion 5 is inserted into and compresses the elastic seal, the two sides of the elastic seal will tilt upwards. Because the annular elastic protrusion 6 is embedded in the annular groove, even if the two sides of the elastic seal tilt upwards, there is no gap between the elastic seal and the end face of the socket 1.

[0043] In this embodiment, the socket 1 has two annular grooves, and the first sealing ring 4 has two corresponding annular elastic protrusions 6. The annular protrusions 5 are located between adjacent annular grooves. Of course, the number of annular grooves can also be one and only located on one side of the annular protrusions 5, or it can be three, four, etc. The peripheral sidewall of the connector 3 has a sealing groove, and a second sealing ring 7 is provided in the sealing groove.

[0044] The connecting assembly includes two sets of latches 8 and latches 9 respectively located on both sides of the plug 2. The latches 8 and latches 9 are respectively located on the socket 1 and the plug 2. The latches 8 extend toward the plug 2 and are fastened to the plug 2.

[0045] The plug 2 has a protrusion on the outer wall corresponding to the buckle 8 and the ear 9, and a guide groove 10 is provided on the protrusion. The buckle 8 passes through the guide groove 10. The guide groove 10 can guide the buckle 8 so that the buckle 8 and the ear 9 can be smoothly engaged. The protrusion specifically includes two ears 11, and the guide groove 10 is located between adjacent ears 11.

[0046] Preferably, the two sets of clips 8 and latches 9 are of different sizes, and the dimensions of the two guide grooves 10 correspond to the dimensions of the two clips 8 respectively. In this design, the widths of the two clips 8 are different, and the corresponding widths of the guide grooves 10 and clips 8 are also different. The different widths of the two guide grooves 10 and clips 8 allow the guide grooves 10 to not only serve a guiding function but also a foolproof function, preventing the larger clip 8 from being inserted into the smaller guide groove 10. This is easily understood, as the pins on the waterproof line have specific insertion requirements; the foolproof design of the guide grooves 10 and clips 8 being of different sizes prevents incorrect insertion.

[0047] Furthermore, each of the socket 1 and plug 2 has an indicator mark 12 on its outer wall, with the two indicator marks 12 corresponding to each other. When the socket 1 and plug 2 are plugged in, the two indicator marks 12 are on the same side, which can also serve as a foolproof method.

[0048] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they shall still fall within the protection scope of the present invention.
