[0001] This utility model relates to the field of connector housing technology, specifically a high-density serial connector housing. Background Technology

[0002] With the trend of highly integrated electronic devices, high-density serial connectors, as key components for signal transmission, directly affect the overall performance of the equipment due to the stability of their housing structure and assembly efficiency. Existing connector housings often suffer from structural design flaws: traditional connection methods often rely on fasteners such as screws, resulting in cumbersome assembly processes that not only reduce production efficiency but also easily lead to connection failure due to loose fasteners; some housings lack reliable limiting structures for their plastic bodies and covers, making them prone to circumferential rotation or axial loosening during use, affecting the protection of internal components; and hardware components, as key parts for enhancing structural strength, lack sufficient positioning accuracy, making them prone to displacement during assembly or use, leading to a decrease in the overall stability of the housing. Utility Model Content

[0003] To overcome the shortcomings of existing technical solutions, this utility model provides a high-density serial connector housing, which can effectively solve the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A high-density serial connector housing includes a plastic body, a plastic cover, and metal parts;

[0006] The plastic body has an open assembly cavity extending along its length. One side wall of the assembly cavity protrudes outward to form a first connecting part. The plastic cover is adapted to cover the opening side of the assembly cavity. The plastic cover has a second connecting part corresponding to the position of the first connecting part. The first connecting part and the second connecting part are covered and fixed by snap-fit ​​or fitting.

[0007] The hardware is sandwiched between the plastic body and the plastic cover. The hardware has a clearance opening in the mating area of ​​the first connecting part and the second connecting part, and axial positioning is achieved by the snapping force of the first connecting part and the second connecting part.

[0008] As a further description of the above technical solution, the first connecting part is a barbed hook-shaped locking block that protrudes along the width direction of the plastic body, the second connecting part is an L-shaped locking groove that is adapted to the barbed hook-shaped locking block, and the clearance opening of the hardware is sleeved on the outside of the locking block.

[0009] As a further description of the above technical solution, the inner wall of the assembly cavity is provided with a plurality of positioning ribs along the length direction, and the plastic cover is provided with a positioning groove on the side facing the assembly cavity. The positioning ribs are embedded in the positioning groove to restrict the circumferential rotation of the plastic cover.

[0010] As a further description of the above technical solution, the hardware includes a flat main body plate, the two ends of which are bent downward to form limiting flanges, the limiting flanges abutting against the two side surfaces of the plastic body to limit the displacement of the hardware in the length direction.

[0011] As a further description of the above technical solution, the main body plate is provided with a plurality of positioning through holes, and the plastic body is provided with positioning posts at corresponding positions.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The high-density serial connector housing of this utility model has at least one of the following beneficial effects during use:

[0015] Firstly, structural stability is significantly improved. The plastic body and the cover are irreversibly mechanically locked together by a hook-shaped locking block and an L-shaped locking groove, ensuring a tight fit and resistance to impact and vibration, effectively preventing loosening. Positioning ribs and grooves restrict the circumferential rotation of the cover, while the hardware limiting flanges constrain displacement in the length direction. Multiple limiting mechanisms ensure the overall structural stability and guarantee a stable working environment for internal components. Secondly, assembly efficiency is significantly improved. The positioning posts of the plastic body and the positioning through holes of the hardware achieve pre-positioning, reducing assembly and adjustment time. The snap-fit ​​assembly eliminates the need for additional fasteners, simplifying the process and facilitating automated mass production, thus reducing labor costs. Thirdly, ease of operation is enhanced. The anti-slip texture of the plastic cover increases friction, effectively preventing slippage during insertion, removal, or maintenance, improving operational reliability, and making it suitable for complex industrial scenarios.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-3 As shown, this utility model provides a high-density serial connector housing, including a plastic body 1, a plastic cover 2, and hardware parts 3.

[0023] The plastic body 1 and the plastic cover 2 are locked together by a snap-fit ​​or interlocking structure of the first connecting part 12 and the second connecting part 21. The open assembly cavity 11 of the plastic body 1 provides space for internal components. The first connecting part 12 on one side wall and the corresponding second connecting part 21 of the plastic cover 2 form a mechanical engagement, tightly binding the two together through a snap-fit ​​force. When a hook-type locking block and an L-shaped locking groove are used, the hook-type locking block protrudes along the width direction of the plastic body 1 and can be precisely embedded into the L-shaped locking groove of the plastic cover 2, forming an irreversible mechanical lock and ensuring a stable connection between the plastic body 1 and the cover.

[0024] The plastic body 1 has an open assembly cavity 11 extending along the length direction. One side wall of the assembly cavity 11 protrudes outward to form a first connecting part 12. The plastic cover 2 is adapted to cover the opening side of the assembly cavity 11. The plastic cover 2 is provided with a second connecting part 21 corresponding to the position of the first connecting part 12. The first connecting part 12 and the second connecting part 21 are covered and fixed by snap-fit ​​or fitting.

[0025] The hardware component 3 is clamped between the plastic body 1 and the plastic cover 2, achieving precise positioning through multiple structures. The hardware component 3 has an clearance opening 31 corresponding to the mating area of ​​the first connecting part 12 and the second connecting part 21, which is fitted onto the outside of the barbed locking block. When the plastic body 1 and the cover are engaged, the engaging force of the two components forms an axial positioning for the hardware component 3, limiting its axial displacement. The positioning post 14 of the plastic body 1 passes through the positioning through hole 34 of the main plate 32 of the hardware component 3, achieving pre-positioning of the hardware component 3 and ensuring that the hardware component 3 is in the correct position from the initial assembly stage.

[0026] The hardware component 3 is sandwiched between the plastic body 1 and the plastic cover 2. The hardware component 3 has an avoidance opening 31 in the mating area of ​​the first connecting part 12 and the second connecting part 21, and axial positioning is achieved by the snapping force of the first connecting part 12 and the second connecting part 21.

[0027] The positioning ribs 13 on the inner wall of the assembly cavity 11 are arranged along the length direction. When the plastic cover 2 is closed, the positioning ribs 13 are embedded in the positioning grooves 22 on the side of the cover facing the assembly cavity 11, forming a circumferential limiting structure to restrict the circumferential rotation of the plastic cover 2 and ensure the stability of the overall structure. At the same time, the anti-slip textures 23 on the surface of the plastic cover 2 away from the plastic body 1 are distributed in a serrated or striped pattern along the length direction, increasing the friction during operation and facilitating gripping during assembly and insertion / removal.

[0028] To further explain, the first connecting part 12 is a barbed block that protrudes along the width direction of the plastic body 1, the second connecting part 21 is an L-shaped slot that is adapted to the barbed block, and the clearance opening 31 of the hardware 3 is sleeved on the outside of the block.

[0029] The hook-shaped locking block and the L-shaped locking groove fit together tightly, which can withstand a certain amount of external impact and vibration, ensuring that the plastic body 1 is firmly connected to the cover and avoiding loosening during use.

[0030] Furthermore, the inner wall of the assembly cavity 11 is provided with a plurality of positioning ribs 13 along the length direction, and the plastic cover 2 is provided with a corresponding positioning groove 22 on the side facing the assembly cavity 11. The positioning ribs 13 are embedded in the positioning groove 22 to restrict the circumferential rotation of the plastic cover 2.

[0031] The cooperation between the positioning rib 13 and the positioning groove 22 restricts the circumferential rotation of the plastic cover 2, and the limiting flange 33 restricts the displacement of the hardware 3 in the length direction. The combined effect of multiple limiting structures greatly improves the overall structural stability of the connector housing and ensures the consistency of the working environment of the internal components.

[0032] Furthermore, the hardware component 3 includes a flat main body plate 32, with both ends of the main body plate 32 bent downwards to form limiting flanges 33. These limiting flanges 33 abut against the side surfaces of both ends of the plastic main body 1, restricting the longitudinal displacement of the hardware component 3. The limiting flanges 33 at both ends of the main body plate 32 abut against the side surfaces of both ends of the plastic main body 1, effectively restricting the longitudinal displacement of the hardware component 3.

[0033] Furthermore, the main body plate 32 is provided with a plurality of positioning through holes 34, and the plastic body 1 is provided with positioning posts 14 at corresponding positions. The positioning posts 14 are inserted into the positioning through holes 34 for pre-positioning of the hardware parts 3.

[0034] The pre-positioning design of the positioning post 14 of the plastic body 1 and the positioning through hole 34 of the hardware part 3 allows for quick determination of the position of the hardware part 3 in the early stages of assembly, reducing adjustment time during the assembly process and improving assembly accuracy. The snap-fit ​​and interlocking assembly method eliminates the need for additional fasteners, simplifying the assembly process, facilitating automated mass production, and reducing labor costs.

[0035] Furthermore, the surface of the plastic cover 2 away from the plastic body 1 is provided with anti-slip texture 23, which is distributed in a serrated or striped pattern along the length of the plastic cover 2. The anti-slip texture 23 on the surface of the plastic cover 2 increases the friction during operation, effectively preventing slippage when plugging or unplugging connectors or performing maintenance operations, thus improving the convenience and reliability of operation, and is especially suitable for complex operating scenarios such as industrial environments.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
