Description

Technical Field

[0001] This utility model relates to the field of connectors, specifically a connector device. Background Technology

[0002] Connectors are used to connect different circuits or components, ensuring the transmission of signals and power. They are widely used in aerospace, automotive, and industrial machine tools. Water and dust resistance are crucial for the normal operation of connectors in complex environments, directly affecting the safety, lifespan, and user experience of the equipment.

[0003] In existing technologies, the sealing function of connector devices is achieved by sealing connectors, that is, an adapter structure is set between the board-end connector and the wire-end connector, and the board-end connector and the wire-end connector are sealed within the adapter structure. Different products require different connectors, and the sealing structure in the aforementioned solution needs to be redesigned and verified in new projects, and cannot be directly transferred to other products.

[0004] Therefore, it is necessary to design a structure to improve the above problems. Utility Model Content

[0005] This utility model provides a connector device whose sealing performance is achieved through a housing structure. By replacing the connector unit within the housing structure, the sealing structure can be adapted to different projects and meet the waterproof and dustproof performance requirements of various products. The purpose of this utility model is achieved through the following solution:

[0006] A connector device includes a housing structure and a connector unit located inside the housing structure. The housing structure includes a front cover, a front shell, a rear shell, a rear plug, a housing sealing ring, and a wire harness sealing ring. The connector unit includes a circuit board, a board-end connector, and a wire-end connector. The front cover is fixed to the front shell. An annular groove is provided on the contact surface between the front shell and the rear shell, and the housing sealing ring is placed in this annular groove. The front shell and rear shell are fixed by bolts. The wire harness sealing ring is located inside the rear shell, and the rear plug is installed at the end of the rear shell. The front end of the wire harness sealing ring abuts against a limiting surface inside the rear shell, and the rear end of the wire harness sealing ring abuts against the rear plug. In existing connector devices, the sealing function is achieved by a sealing connector, i.e., an adapter structure with a center pin, an insulator, and an outer conductor is provided. The board-end connector and the wire-end connector are respectively inserted into the two ends of the adapter structure, and waterproof adhesive is applied and a sealing ring is placed at the connection point for sealing. However, the connector structures of different products vary, and the aforementioned sealing connector cannot be easily transferred to other products. This solution improves the housing structure. The improved connector device achieves a sealing function through the housing, specifically by fixing the front cover to the front shell, the front shell to the rear shell, and the rear shell to the rear plug, forming a sealed, enclosed space inside the housing structure to house the connector unit. Subsequently, the connector unit within the housing structure can be replaced according to the needs of different projects, enabling the platform-based use of the sealed structure.

[0007] Preferably, the head of the front housing forms a cavity, the circuit board is located in the cavity and fixed to the front housing; the tail of the front housing and the rear housing together form an accommodating space, and the board-end connector and the wire-end connector are located in the accommodating space. In the original structure, the board-end connector is connected to the wire-end connector through an adapter structure, resulting in multiple connection points and varying degrees of signal loss at each connection point. In this solution, the board-end connector connects directly to the wire-end connector without the need for an adapter structure, reducing connection points and lowering signal loss.

[0008] Preferably, the front cover is embedded within the cavity of the front housing. This embedded design improves the overall impact resistance of the connector assembly and enhances its mechanical reliability.

[0009] Preferably, the front cover and the front shell are fixed by ultrasonic welding. Ultrasonic welding can instantly melt the material and cool it to solidify, with a short welding cycle; it can form a homogeneous weld at the welding cross-section with high tensile strength; the welding accuracy can reach the micrometer level, and the reliability is high.

[0010] Preferably, the housing structure further includes a magnet, and a recess is provided on the outer surface of the front housing, with the magnet disposed in the recess. Connector devices are typically fixed in the application environment using brackets, but this is inconvenient when installation space is limited. By providing a magnet on the surface of the connector device, it can be directly attracted to the application environment, reducing installation limitations.

[0011] Preferably, the magnet is inserted into the recess by hot pressing.

[0012] The beneficial effects of this utility model are as follows: It provides a connector device that achieves the sealing function through a housing structure. The connector unit inside the housing structure can be replaced according to the needs of different products, realizing the standardized application of the sealed housing structure and shortening the verification cycle of product sealing performance.

Detailed Implementation

[0021] This application provides a connector device whose sealing housing structure can be adapted to different products, realizing the platform-based application of the sealing structure in similar products.

[0022] The technical solution in this application is to solve the above-mentioned technical problems, and the overall approach is as follows:

[0023] A connector device comprises a housing structure and connector units. By fixing the front cover to the front shell, the front shell to the rear shell, and the rear shell to the rear plug, a waterproof and dustproof sealed space is formed inside the housing structure. Because the housing structure becomes a sealed structure, the connector installed inside the housing structure can be a non-sealed connector. Subsequently, only the non-sealed connector needs to be replaced, and the sealed housing structure can be transferred to other products.

[0024] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0025] like Figures 1 to 6 The following is an embodiment of this application:

[0026] A connector device 1 comprises a housing structure 20 and a connector unit 30, the connector unit 30 being located inside the housing structure 20. The housing structure 20 includes a front cover 201, a front shell 202, a rear shell 203, a rear plug 204, a housing sealing ring 205, and a wire harness sealing ring 206. The connector unit 30 includes a circuit board 301, a board-end connector 302, and a wire-end connector 303.

[0027] The front cover 201 and the front shell 202 are fixed together. Specifically, a cavity 2023 is formed in the head of the front shell 202, and the front cover 201 is embedded in this cavity 2023 and fixed to the front shell 202 by ultrasonic welding. This embedded design of the front cover 201 occupies less installation space and can improve the overall impact resistance of the connector device 1, making the mechanical performance of the product more reliable. Ultrasonic welding has the advantages of instantaneous melting of materials and short cooling time, forming a homogeneous weld at the welding section of the front cover 201 and the front shell 202, with high tensile strength and good sealing effect. Other methods can also be used to fix the front cover 201 and the front shell 202, such as laser welding and adhesive fixing.

[0028] The tail of the front shell 202 and the rear shell 203 together form an accommodating space 2024. An annular groove 2021 is provided on the contact surface of the front shell 202 and the rear shell 203. This annular groove 2021 can be located in the front shell 202, the rear shell 203, or both. A shell sealing ring 205 is placed in the annular groove 2021, and the cross-sectional height of the shell sealing ring 205 can be set to be greater than the depth of the annular groove 2021. The front shell 202 and the rear shell 203 are fixed by bolts 2022. During the tightening of the bolts 2022, the shell sealing ring 205 is compressed and deformed, filling the gap between the front shell 202 and the rear shell 203, preventing moisture, dust, and other impurities from seeping into the accommodating space 2024.

[0029] The circuit board 301 is located in the cavity 2023 and is fixed to the front shell 202 by bolts or screws, or by adhesive, heat fusion, or other methods. The board-end connector 302 is connected to the wire-end connector 303, both of which are installed in the accommodating space 2024. The board-end connector 302 is connected to the circuit board 301 located in the cavity 2023. In existing solutions, the board-end connector and the wire-end connector are respectively inserted into the two ends of an adapter structure with a center pin, insulator, and outer conductor. Waterproof adhesive is applied and sealing rings are placed at the connection points between the adapter structure and the board-end connector, and between the adapter structure and the wire-end connector, to achieve the sealing function of the entire connector device. This structure has many connection points for signal transmission, resulting in high loss. The connector in this solution is a non-sealed connector; the board-end connector 302 is directly connected to the wire-end connector 303. This reduces the number of connection points during signal transmission, resulting in better overall transmission quality.

[0030] The wire harness of the wire connector 303 needs to extend beyond the rear housing 203. A wire harness sealing ring 206 is provided inside the rear housing 203, and the wire harness sealing ring 206 is fitted onto the outer surface of the wire harness. A rear plug 204 is installed at the end of the rear housing 203. The front end of the wire harness sealing ring 206 abuts against the limiting surface 2031 inside the rear housing 203, and the rear end of the wire harness sealing ring 206 abuts against the rear plug 204. By filling the internal gap at the end of the rear housing 203, the sealing performance of the connector device 1 is enhanced.

[0031] The housing structure 20 also includes a magnet 207. A recess 2025 is provided on the outer surface of the front housing 202, and the magnet 207 is placed in the recess 2025. The magnet 207 is then inserted into the recess 2025 by hot pressing. The connector device 1 typically requires a bracket for installation, but placing a bracket is inconvenient in scenarios with limited installation space. By embedding the magnet 207 on the surface of the housing structure 20, the connector device 1 can be directly attracted to the usage scenario using magnetism, making operation convenient.

[0032] In summary, this utility model relates to a connector device. By fixing the front cover and front shell, the front shell and rear shell, and the rear shell and rear plug, a closed space is formed within the housing structure of the connector device. The housing structure can prevent moisture, dust, and other impurities from entering the closed space, thus meeting the sealing requirements of the entire connector device. Setting the connector unit inside the housing structure as a non-sealed connector does not affect the sealing performance of the connector device; the sealing structure is transferred from the original sealed connector to the housing. If the sealing structure of existing connector devices is to be migrated to new products, the sealing connector structure must be redesigned. Different products require different connector units. The sealing function of this solution is achieved by the housing structure; only the internal connector unit needs to be replaced, and the sealing structure can be used for different products. Therefore, the sealing structure of this solution can serve as a standardized structure, enabling platform-based development and design.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
