Universal replaceable housing assembly and electrical connector

Abstract

A universal, replaceable housing assembly and electrical connector are disclosed. The housing assembly includes a housing with floating mounting holes, fixed mounting holes, and self-locking nut mounting holes. Alternatively, the housing may have a first replaceable module providing the floating mounting hole structure; a second replaceable module providing the fixed mounting hole structure; or a third replaceable module providing the self-locking nut mounting hole structure. The housing has different mounting hole structures, allowing selection based on needs during installation, greatly facilitating the modification and expansion of weapon equipment and saving costs for manufacturers. Because the saddle-shaped mounting block can be movably engaged in the saddle-shaped groove on the flange edge of the housing, different mounting hole structures can be achieved by replacing different modules. The electrical connector provided by this invention includes the aforementioned housing assembly.

Description

Technical Field

[0001] This invention relates to the field of electrical connector technology, and more particularly to a universal replaceable housing assembly and electrical connector. Background Technology

[0002] Currently, based on the structure of the mounting holes, electrical connectors typically have common mounting methods such as fixed mounting, floating mounting, and self-locking nut mounting. Depending on the positional relationship between the connector and the mounting panel, connector installation can be categorized into various mounting methods such as front-panel mounting, rear-panel mounting, and through-wall mounting.

[0003] Typically, connector housings vary depending on the user's installation method and form. For example, patent CN217522313U discloses a self-floating electrical connector with a through-wall mounting structure. The housing has a circumferentially oriented limiting groove that mates with a mounting panel. The width of the limiting groove and the thickness of the mounting panel have a certain amount of floating space, as does the bottom of the limiting groove and the mounting hole on the mounting panel. Several protrusions are provided on the sidewalls of the limiting groove. By providing these protrusions, during mating, the surface contact between the housing and the mounting panel becomes multi-point contact, significantly reducing sliding friction in the mating direction. Another example is patent CN213905745U, which discloses a shielded electrical connector housing. The top housing has a first fixing plate integrally formed on both sides, and the bottom housing has a second fixing plate integrally formed on both sides. The second fixing plate is detachably connected to the first fixing plate via screws.

[0004] In the existing technology, each installation method corresponds to a different connector housing, and even different installation methods require different connector housings, which imposes a significant economic burden on manufacturers, is not conducive to user operation, and seriously restricts the development of weapon models. Summary of the Invention

[0005] The main objective of this invention is to provide a universal and replaceable housing assembly and electrical connector. Users can use the connector housing assembly and electrical connector in various mounting configurations without changing the mounting holes, which greatly facilitates the modification and expansion of weapon equipment and also saves economic costs for manufacturers.

[0006] To achieve the above objectives, on the one hand, the present invention proposes a universal replaceable housing assembly, including a housing, on which a floating mounting hole structure, a fixed mounting hole structure, and a self-locking nut mounting hole structure are simultaneously provided; or a first replaceable module is provided on the housing, so that the housing has a floating mounting hole structure; or a second replaceable module is provided on the housing, so that the housing has a fixed mounting hole structure; or a third replaceable module is provided on the housing, so that the housing has a self-locking nut mounting hole structure.

[0007] Preferably, the first replaceable module includes a saddle-shaped mounting block and a floating sleeve disposed within the saddle-shaped mounting block; the second replaceable module includes a saddle-shaped mounting block; the third replaceable module includes a saddle-shaped mounting block and a self-locking nut disposed within the saddle-shaped mounting block; a fixing ring is provided on the self-locking nut, and multiple fixing teeth are evenly distributed on the outer circumferential surface of the fixing ring; a saddle-shaped groove is provided on the flange edge of the housing, and the saddle-shaped mounting block is movably engaged within the saddle-shaped groove; the thickness of the saddle-shaped mounting block is the same as the thickness of the flange edge of the housing; the floating mounting hole structure includes the floating sleeve; the self-locking nut mounting hole structure includes the self-locking nut; and the fixed mounting hole structure includes a through hole.

[0008] Preferably, the floating sleeve includes a hollow cylindrical body with open ends, and a first limiting ring and a second limiting ring respectively disposed at both ends of the cylindrical body.

[0009] Preferably, when the housing is simultaneously provided with a floating mounting hole structure, a fixed mounting hole structure, and a self-locking nut mounting hole structure: the floating sleeve is installed on the flange edge of the housing to form a floating mounting hole structure; the first limiting ring and the second limiting ring are located on both sides of the flange edge of the housing, and the hollow cylinder is movably inserted into the flange edge of the housing; the through hole is provided on the flange edge of the housing to form a fixed mounting hole structure; and the self-locking nut is embedded in the flange edge of the housing to form a self-locking nut mounting hole structure.

[0010] Preferably, a recessed platform is provided on the upper end face of the flange edge of the shell, and the first limiting ring is disposed in the recessed platform. The length of the hollow cylinder part is greater than the distance from the bottom surface of the recessed platform to the lower end face of the flange edge of the shell, and the distance h1 from the lower end face of the flange edge of the shell to the top surface of the first limiting ring is less than the thickness h2 of the flange edge of the shell.

[0011] Preferably, when the housing is provided with a first replaceable module, the first limiting ring and the second limiting ring are located on both sides of the saddle-shaped mounting block, and the hollow cylindrical part is movably inserted into the saddle-shaped mounting block to form a floating mounting hole structure.

[0012] Preferably, a circular countersunk hole is provided on the saddle-shaped mounting block, and the first limiting ring is disposed in the circular countersunk hole. The length of the hollow cylindrical part is greater than the distance from the bottom surface of the circular countersunk hole to the lower end surface of the saddle-shaped mounting block, and the distance h4 from the lower end surface of the saddle-shaped mounting block to the top surface of the first limiting ring is less than the thickness h5 of the saddle-shaped mounting block.

[0013] Preferably, when a second replaceable module is provided on the housing, the through hole is provided on the saddle-shaped mounting block to form a fixed mounting hole structure.

[0014] Preferably, when a third replaceable module is provided on the housing, the self-locking nut is embedded in the saddle-shaped mounting block to form a self-locking nut mounting hole structure.

[0015] On the other hand, the present invention also provides an electrical connector that includes the aforementioned housing assembly.

[0016] Due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows: (1) In this invention, the shell is provided with floating mounting hole structure, fixed mounting hole structure and self-locking nut mounting hole structure at the same time, so that the shell has different mounting hole structures. During installation, the selection can be made according to the needs, which greatly facilitates the modification and expansion of weapon equipment, and also saves the economic cost of the manufacturer.

[0017] (2) In this invention, since a first replaceable module, a second replaceable module, or a third replaceable module is provided on the housing, and each of the first, second, and third replaceable modules is provided with a saddle-shaped mounting block, and since the saddle-shaped mounting block can be movably engaged in the saddle-shaped groove on the flange side of the housing, different mounting hole structures can be provided on the housing by replacing different modules during use. During use, the appropriate module can be selected as needed to make the housing meet different corresponding installation requirements, which greatly facilitates the modification and expansion of weapon equipment, and also saves economic costs for manufacturers.
