Description

Technical Field

[0001] This utility model relates to the field of waterproof connector technology, specifically a waterproof connector with a double sealing structure. Background Technology

[0002] A waterproof connector is a connection device that maintains stable electrical performance in humid or water-immersed environments. It is mainly used to prevent moisture intrusion that could cause circuit failures or equipment damage. Its core function is to ensure that equipment can operate stably for a long time in harsh environments.

[0003] Currently, waterproof connectors suffer from a single sealing protection structure, which makes them prone to sealing failure after prolonged use. This renders the waterproof connector unusable, significantly shortening its lifespan. Furthermore, it is inconvenient to regularly disassemble and inspect the sealing protection structure.

[0004] Therefore, a novel waterproof connector with a double-sealing structure is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a waterproof connector with a double sealing structure to solve the problems mentioned in the background art, such as the waterproof connector being prone to sealing failure after long-term use due to its single sealing protection structure, which makes the waterproof connector unusable, greatly shortens its service life, and makes it inconvenient to disassemble and inspect the sealing protection structure regularly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof connector with a double sealing structure, comprising a connector body, an outer sealing component, an inner sealing component, and a waterproof component. The connector body includes a first outer sleeve and a second outer sleeve, the second outer sleeve being located on the right side of the first outer sleeve. The waterproof components are all located on the inner walls of the first and second outer sleeves. The outer sealing component and the inner sealing component are located outside and inside the first and second outer sleeves, respectively. The inner sealing assembly includes an inner sealing ring and a mounting base. The inner sealing ring is fixedly connected to the inside of the right side of the first outer sleeve, and the mounting base is fixedly connected to the left side of the second outer sleeve. The outer end of the mounting base has multiple sets of grooves that are evenly spaced in a ring. An inner block is fixedly connected to the right side of the inside of the groove. Multiple sets of slide rails are arranged laterally on the inner wall of the groove. Multiple sets of auxiliary blocks are fixedly connected to the inner wall of the inner sealing ring. As a further technical solution of this utility model, the auxiliary block corresponds one-to-one with the slide rail, and the auxiliary block is slidably connected to the outside of the slide rail. The right side of the auxiliary block and the inside of the inner block form an interlocking connection. The inner wall of the sealing inner ring is in contact with the outer end of the mounting base.

[0007] As a further technical solution of this utility model, an upper connecting seat and a lower connecting seat are sequentially sleeved on the outside of the connection between the first outer sleeve and the second outer sleeve from top to bottom. An adhesive layer is fixedly connected to the inner wall of both the upper connecting seat and the lower connecting seat. An inner sealing ring is attached to the inner wall of the adhesive layer. The inner wall of the inner sealing ring is in contact with the outer wall of the first outer sleeve and the second outer sleeve. A limit collar is fixedly sleeved on the outside of both the first outer sleeve and the second outer sleeve.

[0008] As a further technical solution of this utility model, the two sides of the upper connecting seat and the lower connecting seat are respectively fitted with the inner sides of the two sets of limiting collars, and the bottom of both ends of the upper connecting seat and the top of both ends of the lower connecting seat are fixedly connected with external plates.

[0009] As a further technical solution of this utility model, a positioning cylinder is provided through the interior of the outer plate, and a fastening bolt is provided through the internal thread of the positioning cylinder.

[0010] As a further technical solution of this utility model, the inner walls of the first outer sleeve and the second outer sleeve are provided with multiple sets of inner grooves at equal intervals in the transverse direction, and the inner walls of the first outer sleeve and the second outer sleeve are fitted with waterproof sleeves.

[0011] As a further technical solution of this utility model, the waterproof sleeve is horizontally fixedly connected to the outside at equal intervals, and the fixing rods are inserted into the inside of the inner groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the waterproof connector with a double sealing structure not only realizes the internal sealing protection function and the external sealing protection function, but also realizes the fixed waterproof function; (1) By providing a mounting base, a sealing inner ring, an auxiliary block, a slide rail, an inner connecting block and a groove, the connection between the first outer sleeve and the second outer sleeve is fitted together. The auxiliary block is installed on the outside of the slide rail by means of sliding connection, and the mounting base is fixed inside the sealing inner ring by stable inward push. The auxiliary block is fixed in the inner connecting block by means of plug-in connection, which strengthens the firmness between the sealing inner ring and the mounting base, and achieves strong sealing protection for the first outer sleeve and the second outer sleeve, ensuring that the sealing performance of the connection remains stable for a long time. (2) By setting up an upper connecting seat, a lower connecting seat, an outer plate, a positioning cylinder, fastening bolts and an inner sealing ring, the upper connecting seat and the lower connecting seat are respectively fitted onto the outside of the first outer sleeve and the second outer sleeve. The outer plates are in contact with each other. The fastening bolts can be moved downward according to the thread direction of the inner wall of the positioning cylinder to optimize the connection method of the first outer sleeve and the second outer sleeve. The inner walls of the upper connecting seat and the lower connecting seat are added with an adhesive layer. The inner sealing ring cooperates with the sealing inner ring to achieve double sealing protection for the first outer sleeve and the second outer sleeve, greatly improving the sealing protection force. The two sets of limiting collars play a role in limiting and fixing the two sides of the upper connecting seat and the lower connecting seat. (3) By setting a fixing rod, a waterproof sleeve and an inner groove, the inner walls of the first outer sleeve and the second outer sleeve are both added with waterproof sleeves, which improves the waterproofness of the first outer sleeve and the second outer sleeve themselves, and provides a safe waterproof protection space to prevent water from entering and damaging the internal structure. The fixing rod is installed into the corresponding inner groove by plugging and connecting, which enhances the connection between the waterproof sleeve and the inner walls of the first outer sleeve and the second outer sleeve, and effectively prevents the waterproof sleeve from shifting during use.
