[0016] The present invention will be described in further detail below with reference to the accompanying drawings.

[0017] This embodiment discloses a rectangular connector waterproof joint, such as Figures 1 to 3 As shown, it includes a connector housing 1 and a connector body 2. The connector body 2 includes a connector body 21, an annular sealing sleeve 3, a cap 22, and a waterproof gasket 4. The connector body 2 has a through hole in the center for the power line to pass through. The connector body 21 is provided with a cavity adapted to the annular sealing sleeve 3, and the annular sealing sleeve 3 is disposed in the cavity. The lower end of the connector body 21 is provided with an external thread, which is threadedly connected to the connector housing 1. The waterproof gasket 4 is disposed between the connector body 21 and the connector housing 1. The upper end of the connector body 21 is provided with an external thread, and the inner cavity of the cap 22 is provided with an internal thread. The upper end of the connector body 21 is threadedly connected to the cap 22. The threaded connection is simple in structure, easy to assemble and disassemble, and convenient for maintenance and repair. The threaded connection is self-locking, which can prevent loosening due to vibration or impact to a certain extent.

[0018] Further improvement, a wedge-shaped boss 213 is provided in the cavity, and the annular sealing sleeve 3 is arranged on the wedge-shaped boss 213. The wedge-shaped boss 213 supports the annular sealing sleeve 3, so that the annular sealing sleeve 3 is fixed in the axial position and is not easy to slip off with the movement of the cable to destroy the waterproof seal.

[0019] As a further improvement, the inner cavity of the top of the cap 22 is provided with a cap bevel 221, which contacts the connector body 21. The opening of the cap 22 is provided with a circular arc surface. The slope of the cap bevel 221 is greater than the slope of the upper end of the connector body 21. When the cap 22 and the connector body 21 are screwed together, they will squeeze the upper end of the connector body 21, and the cap bevel 221 will apply a radially inward force to the connector body 21.

[0020] As a further improvement, the connector body 21 is provided with a loop-shaped sheet structure 211 at the top port. The sheet structure 211 fits in the inner cavity of the tight cap 22. When the cap 22 is tightened, the sheet structure 211 is subjected to the force from the inner cavity of the cap 22 and deforms. The sheet structure 211 deforms and tightens inward, squeezing the annular sealing sleeve 3 inside. The force exerted by the loop-shaped sheet structure 211 on the inner portion is relatively uniform, preventing the annular sealing sleeve 3 from forming gaps due to uneven force, thereby achieving good waterproof performance.

[0021] Further improvement, the upper end of the annular sealing sleeve 3 is a conical closing, and the material is rubber. The inner diameter of the conical closing is larger than the cable, so that the cable can pass smoothly when the cap 22 is not tightened; after the cap 22 is tightened, the conical closing is easy to form a better fit to the inner surface of the connector body 21, and it is not easy to produce gaps under deformation, with good waterproof performance, and it can also press and clamp the outer surface of the cable to prevent the cable from sliding easily. The inner diameter of the annular sealing sleeve 3 is provided with an inner groove 31, which increases the friction between the annular sealing sleeve 3 and the cable, making the fit more reliable, and when the annular sealing sleeve 3 is deformed by force, the inner groove 31 can fit a certain deformation to avoid wrinkles and gaps in the annular sealing sleeve 3, with good waterproof performance; because the working environment of the rectangular connector requires the cable to be in a state that needs to be bent for a long time, the flexible rubber material of the connection end can provide better support for the external cable than the angled rigid surface, reduce fatigue loss caused by bending stress, and increase service life.

[0022] Further improvement, the connector body 21 is provided with a protrusion 212, which is a hexagonal nut, making it easy to grasp and making the fitting process very convenient.

[0023] Working principle of the utility model

[0024] The annular sealing sleeve 3 is set in the joint body 21. Since a wedge-shaped boss 213 that fits the annular sealing sleeve 3 is set in the joint body 21, the setting can be completed simply and quickly by matching the annular sealing sleeve with the wedge-shaped boss 213. The cap 22 is installed to the upper end of the joint body 21 through a threaded connection. The cap 22 is in an untightened state where the sheet structure 211 has not yet contacted the cap inclined surface 221. The waterproof gasket is set at the lower end of the joint body 21 close to the boss 212.

[0025] Pass the cable through the inner diameter through hole. Since the outer diameter of the cable is slightly smaller than the components included in the connector body 2, the process is very smooth and simple. After completing the cable installation, adjust the cable position and connect the connector body 2 and the connector shell through threads so that the waterproof gasket is pressed between the connector body 21 and the connector shell 1 to obtain good waterproof performance. Tighten the cap 22 so that the cap slope 221 squeezes the sheet structure 211. The sheet structure 211 is deformed and tightened under force to apply radial force to the annular sealing sleeve 3, so that the annular sealing sleeve 3 and the cable fit tightly, so that the cable position is fixed and good waterproof performance is obtained. The cable can still be adjusted before the cap 22 is tightened.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
