[0002] Connector housings are used to protect and secure internal electrical connection components, and are widely used in electronics, electrical engineering, and other fields. However, some existing high-strength waterproof connector housings still have the following problems during use: uneven distribution of overall structural strength, with corners and other parts prone to deformation and damage due to external forces; inadequate waterproof sealing design, leading to decreased sealing reliability after long-term use and a risk of water ingress; furthermore, it is difficult to balance lightweight design with strength, with some prioritizing strength at the expense of structural strength. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a high-strength waterproof connector housing, which is equipped with structures such as inner corner reinforcement seats, outer corner reinforcement seats, reinforcement blocks, and rectangular reinforcement frames to enhance strength. It also works with front and rear sealing rings to ensure waterproofing and achieves lightweighting through weight-reduction grooves. This solves the problems of insufficient housing strength, poor waterproof reliability, and difficulty in balancing lightweighting and strength mentioned in the background technology.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength waterproof connector housing, comprising a housing assembly and a front cover assembly arranged in combination. The housing assembly includes a housing shell with an opening at the front end. An inner corner reinforcement seat is provided on the inner side of the opening of the housing shell. The inner corner reinforcement seat is used to enhance the structural strength of the inner corner of the opening of the housing shell and prevent the inner corner from being deformed by external forces. The front cover assembly includes a front cover body. The outer side of the front cover body is provided with a matching connecting portion outer contour corresponding to the opening of the housing shell to ensure connection sealing and facilitate precise docking between the front cover body and the housing shell.

[0007] The outer side of the outer shell is provided with an outer corner reinforcement seat, which is used to enhance the structural strength of the outer corner of the outer shell. The outer shell is also provided with a reinforcement block and a rectangular reinforcement frame. The reinforcement block can locally strengthen the inner side of the shell, and the rectangular reinforcement frame surrounds the outer side of the shell to further enhance the overall strength. The outer side of the outer shell is provided with a screw through-hole assembly hole, and the front cover is provided with a front assembly hole in the middle. The front cover is provided with a screw thread mounting hole corresponding to the screw through-hole assembly hole.
