Description

Technical Field

[0001] This utility model relates to the field of wiring device technology, and more specifically, to a snap-fit ​​structure and external device for plugging in crystal heads. Background Technology

[0002] Currently, RJ45 connectors are widely used in network connection devices to connect cables to device interfaces. Traditional RJ45 connectors typically use mechanical clips to ensure stability, but existing technologies often suffer from insufficient stability during insertion, failing to effectively prevent displacement or loosening. Especially under external vibration or pulling, poor contact can easily occur, leading to signal instability or connection interruption. Furthermore, existing connector structures are usually one-piece designs, limiting access to open-end connections and lacking flexibility and convenience, failing to meet the requirements for connector adaptation and quick plug-and-play functionality. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a snap-fit ​​structure and external device for plugging in crystal heads, in order to solve the above-mentioned problems.

[0004] The present invention adopts the following solution:

[0005] This application provides a snap-fit ​​structure for inserting RJ45 connectors, including an upper cover and a lower cover. The lower cover is integrally formed on an external PCB board. The upper cover is detachably attached to the PCB board via a bracket, and is assembled with the lower cover to form a receiving space for inserting RJ45 connectors. The receiving space is open, and a pin connection module is provided on the lower cover, while a retaining spring is provided on the upper cover. The retaining spring is mounted on the bracket and provides spring force to smoothly limit the RJ45 connector, which enters the receiving space through the opening, to its electrical connection position.

[0006] As a further improvement, the bracket is integrally formed on the upper shell cover, which has a connection portion extending laterally horizontally for locking in external fasteners.

[0007] As a further improvement, the connecting portion is provided on the side edge of the upper shell cover along the left and right directions.

[0008] As a further improvement, a retaining spring is correspondingly installed on one of the connecting parts, one end of the retaining spring is fixed on the inner wall of the connecting part, and the other end of the retaining spring extends to the top of the accommodating space to elastically abut against the crystal head.

[0009] As a further improvement, the pin connection module is disposed on the bottom surface of the lower housing and formed below the accommodating space for electrical connection with the plugged-in crystal head.

[0010] As a further improvement, the upper shell cover and the lower shell bottom are joined together to form a rectangular box shape, and the opening connecting to the accommodating space is in the shape of an interface.

[0011] As a further improvement, the bottom of the lower shell is located on the outer side of the PCB board, and multiple peripheral interfaces are arranged in a regular pattern on the other side of the PCB board.

[0012] This application also provides an external device, including a PCB board and a snap-fit ​​structure configured on the PCB board for inserting a crystal head.

[0013] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0014] The snap-fit ​​structure for inserting RJ45 connectors in this application provides a stable housing space through the assembly connection of the upper cover and the lower base. This ensures that the RJ45 connector will not loosen or fall off due to external forces or vibrations after insertion. Furthermore, since the upper cover and the lower base are detachably connected by a bracket, the snap-fit ​​structure is easy to install and maintain, requiring no complicated fixing measures. The bracket also allows for more flexible assembly positions between the two housings, accommodating different models and sizes of RJ45 connectors. This improves the versatility and applicability of the structure. In particular, the spring clip, through the spring force provided by the bracket, can stably constrain the RJ45 connector at its electrical connection position, avoiding instability during insertion and ensuring a stable and reliable electrical connection.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0021] Example

[0022] Combination Figures 1 to 3 This embodiment provides a snap-fit ​​structure for inserting RJ45 connectors, including an upper cover 1 and a lower cover 2. The lower cover 2 is integrally formed on an external PCB board 3. The upper cover 1 is detachably attached to the PCB board 3 via a bracket 6, and is assembled with the lower cover 2 to form a receiving space for inserting RJ45 connectors. The receiving space is open, and a pin connection module 4 is provided on the lower cover 2, while a retaining spring 5 is provided on the upper cover 1. The retaining spring 5 is mounted on the bracket 6 and provides spring force to smoothly retain the RJ45 connector entering the receiving space through the opening at its electrical connection position.

[0023] The aforementioned snap-fit ​​structure, through the assembly and connection of the upper cover 1 and the lower bottom 2, provides a stable housing space, ensuring that the connection will not loosen or fall off due to external forces or vibrations after the RJ45 connector is inserted. Furthermore, since the upper cover 1 and the lower bottom 2 are detachably connected by the bracket 6, the snap-fit ​​structure is easy to install and maintain, requiring no complicated fixing measures. The bracket 6 also allows for more flexible assembly positions between the two housings, accommodating different models and sizes of RJ45 connectors, thus improving the versatility and applicability of the structure. In particular, the spring clip 5, through the spring force provided by the bracket 6, can smoothly constrain the RJ45 connector at its electrical connection position, avoiding instability during the RJ45 connector insertion process and ensuring a stable and reliable electrical connection.

[0024] In this embodiment, the bracket 6 is integrally formed on the upper cover 1, and has a connecting portion 7 extending horizontally in the side for locking external fasteners. This greatly improves the overall stability of the snap-fit ​​structure, and the bracket 6 and the upper cover 1 form a more robust integral structure, reducing loosening problems caused by external vibration or tension, thereby improving the stability of the RJ45 connector insertion position. In addition, the extended connecting portion 7 provides a convenient interface for locking external fasteners, allowing the snap-fit ​​structure to be easily connected to external devices or fixing devices. The snap-fit ​​structure can be installed more conveniently and reliably, avoiding additional assembly complexity.

[0025] Preferably, the connecting portions 7 are respectively provided on the side edges of the upper cover 1 along the left and right directions. The two connecting portions 7 are formed opposite each other on the left and right sides, so that the upper cover 1 can be stably and conveniently locked on the top of the PCB board 3. Correspondingly, the upper cover 1 and the lower cover 2 are connected to form a whole receiving space with an opening. Moreover, the height distance in the vertical direction can be adjusted more flexibly to adapt to different sizes and types of crystal heads.

[0026] A retaining spring 5 is correspondingly installed on one of the connecting portions 7. One end of the retaining spring 5 is fixed to the inner wall of the connecting portion 7, and the other end extends above the receiving space to elastically abut against the crystal head. On one hand, the cooperation between the retaining spring 5 and the connecting portion 7 provides an effective elastic positioning method. When the crystal head is inserted into the receiving space, the retaining spring 5 stably abuts against the crystal head through its elasticity, ensuring that the crystal head is firmly held in its electrical connection position after insertion, preventing the crystal head from falling off or shifting due to external force or vibration, thereby enhancing the reliability of the connection. On the other hand, the retaining spring 5 can automatically adjust its position according to the insertion depth of the crystal head, maintaining sufficient pressure to stabilize the crystal head. Even if the crystal head size changes slightly, the elasticity of the retaining spring 5 can adapt, ensuring that the crystal head is always in the correct position during insertion, avoiding poor contact due to size mismatch.

[0027] In this embodiment, the pin connection module 4 is disposed on the bottom surface of the lower housing bottom 2 and formed below the accommodating space, for electrical connection with the inserted RJ45 connector. Therefore, the placement of the pin connection module 4 on the bottom surface of the lower housing bottom 2 and its formation below the accommodating space ensures a stable electrical connection between the RJ45 connector and the pins after insertion, helping to maintain the stability of the electrical connection and preventing signal loss or electrical faults due to incomplete insertion or poor contact. It should be understood that the pin connection module 4 is an existing electrical connection structure for RJ45 connector adapter insertion, and therefore will not be described in detail here.

[0028] In this embodiment, the upper cover 1 and the lower cover 2 are joined together to form a rectangular box shape, and the opening connecting to the accommodating space is in the shape of an interface. The rectangular box structure makes the joint between the upper cover 1 and the lower cover 2 more secure, thereby improving the overall sealing performance. This is crucial for protection against dust, water, or other environmental factors, and helps ensure that the snap-fit ​​structure can still function normally in harsh environments.

[0029] In this embodiment, the lower shell bottom 2 is disposed on the outer side of the PCB board 3, and multiple peripheral interfaces 8 are arranged in a regular pattern on the other side of the PCB board 3. Therefore, the lower shell bottom 2's placement on the outer side of the PCB board 3 allows for a more compact and efficient use of space in the entire snap-fit ​​structure, ensuring the rational utilization of the PCB board 3's space and avoiding unnecessary occupation. Simultaneously, it ensures that the peripheral interfaces 8 are arranged in a regular pattern, providing more interfaces and expansion capabilities. Furthermore, since multiple peripheral interfaces 8 are arranged in a regular pattern on the other side of the PCB board 3, users can more easily connect external devices, providing flexible expandability and allowing the device to connect to multiple peripherals, such as network interfaces, sensors, and storage devices, thereby increasing the device's functionality and applicability.

[0030] Referring to the figure, this embodiment also provides an external device, including a PCB board and a snap-fit ​​structure for inserting RJ45 connectors, disposed on the PCB board 3. By integrating the snap-fit ​​structure onto the PCB board 3, the external device simplifies its structural configuration. Users only need to insert the RJ45 connectors to connect to external devices, avoiding additional connecting parts and reducing assembly complexity.

[0031] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
