DETAILED DESCRIPTION

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] like Figures 1 to 6As shown, the utility model provides a sanitary sealed cable connector, including a cable connector shell 1, a soft plastic built-in component 2 and a built-in locking component 3, all of which are provided with an axial inner hole for the cable to pass through; the middle part of the built-in locking component 3 is provided with a shaft shoulder 31 and a first sealing ring 4, the rear part is provided with a first external thread 32 and is connected to the electrical appliance through a thread and relies on the first sealing ring 4 to achieve sealing at the connection, the front outer end is provided with a second external thread 33, and the inner side surface of the front is uniformly distributed with axial first strip-shaped positioning teeth 34 along the circumferential direction; the outer side surface of the soft plastic built-in component 2 is uniformly distributed along the circumferential direction There are second strip-shaped positioning teeth 21 evenly distributed axially. After the soft plastic built-in part 2 is inserted into the inner hole of the built-in locking part 3, it is positioned and engaged through the first strip-shaped positioning teeth 34 and the second strip-shaped positioning teeth 21. The inner side surface of the rear part of the cable connector housing 1 is provided with an internal thread 11 that engages with the second external thread 33. A second sealing ring 5 is provided at the rear end of the cable connector housing 1. The cable connector housing 1 is inserted into the soft plastic built-in part 2 and the soft plastic built-in part 2 is deformed and hugged by the front end. The rear end is threadedly connected to the second external thread 33 and sealed with the electrical surface through the second sealing ring 5.

[0021] In the above solution, steps 35 for a wrench to clamp and rotate are provided on the left and right sides of the front outer side surface of the built-in locking member 3.

[0022] In addition, the cable connector housing 1 is a streamlined structure combining a smooth curved surface and a flat surface.

[0023] In addition, the material of the soft plastic built-in component 2 is environmentally friendly TPU.

[0024] Specifically, the cable connector housing 1 and the built-in locking member 3 are both made of food-grade stainless steel.

[0025] Furthermore, the first sealing ring 4 and the second sealing ring 5 are made of sanitary-grade hydrogenated nitrile rubber.

[0026] Furthermore, the front outer side surface of the cable connector housing 1 is an outer hexagonal structure.

[0027] In this utility model, 316L stainless steel and FDA-compliant food-grade seals are used to hygienically seal the cable in a sterile environment. Seamless installation, good sealing, antibacterial, corrosion-resistant, resistant to detergents, and very easy to clean.

[0028] The first strip-shaped positioning teeth 34 and the second strip-shaped positioning teeth 21 are positioned and engaged, which effectively prevents the soft plastic inner part 2 from rotating when the cable connector housing 1 rotates, thereby preventing the cable from being deformed when tightened.

[0029] Design principles based on hygienic design standards prevent biological and chemical contamination and ensure easy cleaning through the following methods: the streamlined curved surface design of the shell avoids dirt accumulation; the design is free of cavities, gaps and exposed threads.

[0030] Advanced general performance: good sealing, protection grade IP68; standard operating temperature range is -40℃ to +120℃; temperature resistance is -50℃ to 150℃ IP68 (10bar).

[0031] The double sealing ring design is simple and reliable, saving time and cost. The compact design, hidden built-in bolts and wrench flats make it possible to install the housing even when space is limited.

[0032] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any simple modification, equivalent change or modification made to the above embodiment based on the technical principle of the present invention still falls within the scope of the technical solution of the present invention.
