Description

Technical Field

[0001] This invention relates to the field of communication interface technology, and in particular to a communication module interface terminal. Background Technology

[0002] Communication module interface terminals are key components in modern communication systems, enabling signal transmission, power supply, and data exchange between modules and external devices or systems. They are widely used in 5G networks, the Internet of Things (IoT), industrial automation, and automotive electronics. With the widespread adoption of 5G technology, interface terminals must meet requirements for high bandwidth, ultra-low latency, high reliability, and miniaturization to support efficient and stable communication performance. Common interface terminal designs include pin connectors, spring-loaded terminals, and board-to-board connectors, typically employing bolt fixing, spring clips, or magnetic connections to achieve rapid module installation and reliable connection. These terminals must possess mechanical durability, electromagnetic interference resistance, and stability in complex environments to adapt to the diverse needs of 5G infrastructure and IoT devices.

[0003] However, existing communication module interface terminals have certain drawbacks. For example, patent number CN202422478854.2 (publication number CN223194048U) discloses a terminal block that uses conductive spring contacts to connect and fix wires to pins. While simple to operate and tool-free, this spring-loaded connection method is prone to breakage due to material fatigue under long-term use or high-vibration environments, affecting connection stability. Furthermore, while traditional bolt fixing methods provide a secure connection, they require specialized tools, making installation and disassembly cumbersome and time-consuming, hindering rapid maintenance and deployment. These shortcomings limit the application of interface terminals in high-reliability scenarios, necessitating a new design that balances ease of operation and connection reliability to meet the needs of 5G communication and future technological developments.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example

[0035] Reference Figures 1 to 7 The present invention provides a communication module interface terminal, including an interface module 100 and a connection module 200, which aims to achieve fast and reliable plug-in connection and meet the requirements of high bandwidth, ultra-low latency and high reliability of 5G communication modules.

[0036] The interface module 100 includes a housing 101, made of robust metal or high-strength plastic, providing structural support and electromagnetic shielding to protect internal components from external interference. An internal connection cavity 101a provides a sealed space for terminal connections, ensuring stable signal transmission and dust and water resistance. A connection piece 102 is fixedly mounted on the rear wall of the connection cavity 101a. The connection piece 102 is made of highly conductive copper alloy and gold-plated to enhance conductivity and corrosion resistance, ensuring stable electrical contact with the connection module 200, suitable for 5G high-frequency signal transmission. A movable cylinder 104 is fixedly connected to the front wall of the connection cavity 101a via a return spring 103. The return spring 103 is made of highly elastic stainless steel, providing stable rebound force to ensure the movable cylinder 104 quickly resets after unlocking. Its elastic design also optimizes force feedback during insertion and removal, improving the user experience. A rotating cylinder 105 is rotatably connected inside the movable cylinder 104. The movable cylinder 104 and the rotating cylinder 105 together constitute a dynamic locking mechanism, achieving locking and unlocking functions through rotation and sliding. A positioning groove 106 is formed on the upper surface of the rear end of the rotating cylinder 105. The positioning groove 106 accommodates the positioning component 107, precisely controlling the locked state of the rotating cylinder 105 and ensuring the mechanical stability of the connection. The positioning component 107 is located inside the positioning groove 106 and is responsible for locking and releasing the rotating cylinder 105, ensuring a stable connection or smooth separation between the connection module 200 and the interface module 100. The front ends of both the movable cylinder 104 and the rotating cylinder 105 penetrate the front wall of the connection cavity 101a and extend to the outside of the outer shell 101, facilitating user operation while ensuring a compact structure to meet the needs of miniaturized equipment. A connection hole 108 is formed at the center of the interior of both the movable cylinder 104 and the rotating cylinder 105. The connection hole 108 provides a precise guiding channel for the insertion of the connection module 200, ensuring accurate alignment and reliable contact.

[0037] The connection module 200 includes a wire 201, an insulation part 202, and a connector 203. The wire 201 uses a high-performance shielded cable to ensure low-loss transmission of 5G high-frequency signals while also providing electromagnetic interference resistance. The insulation part 202 is made of high-temperature resistant and wear-resistant engineering plastic, providing electrical insulation and mechanical protection to prevent short circuits or signal interference. The connector 203 is made of a highly conductive metal material, matching the connector piece 102 to ensure low-resistance contact, suitable for high-bandwidth data transmission. Both the insulation part 202 and the connector 203 are inserted into the connection hole 108, with the end of the connector 203 penetrating the connection hole 108 and extending into the connection cavity 101a to abut against the contacts of the connector piece 102, forming a stable electrical connection to ensure signal integrity and reliable power transmission.

[0038] Specifically, the inner top wall of the connecting cavity 101a is provided with a telescopic groove 101b, which provides movement space for the positioning component 107, ensuring its smooth movement during locking and unlocking. The positioning component 107 includes a telescopic spring 107a fixedly connected to the inner top wall of the telescopic groove 101b. The telescopic spring 107a is made of high-strength spring steel, providing stable elastic support and ensuring the reliability of the locking and the reset capability. A telescopic block 107b is fixedly connected to the bottom end of the telescopic spring 107a. The telescopic block 107b is made of wear-resistant engineering plastic or metal, reducing friction and ensuring long-term stability. A locking plate 107c is fixedly connected to the bottom end of the telescopic block 107b. The locking plate 107c is a high-strength metal part with a smooth surface to reduce wear. Its bottom end is set in the positioning groove 106, cooperating with the positioning groove 106 to achieve the locking and releasing of the rotating cylinder 105. The locking plate 107c can move back and forth within the positioning groove 106. When it moves to the front end, it can fix the rotating drum 105 in this position through the limiting action of the locking groove 106a, ensuring stable contact between the connecting module 200 and the connecting piece 102. After rotating and moving a certain angle, the locking plate 107c can slide out along the guide slope 106c, allowing the rotating drum 105 to reset. At the same time, the locking plate 107c moves back to its initial state, and the telescopic block 107b moves upward to compress the telescopic spring 107a, providing it with the elastic force for subsequent locking. This design ensures the fast response and high reliability of the locking mechanism, while reducing the operating force and improving the user experience.

[0039] More specifically, the positioning groove 106 consists of a slot 106a and a sliding groove 106b. The slot 106a is located at the front end of the sliding groove 106b and is used for limiting movement in the locked state. The rear wall of the slot 106a and the sliding groove 106b are staggered to form a depth difference to achieve precise positioning of the card plate 107c. The depth of the sliding groove 106b is lower than that of the slot 106a, ensuring smooth sliding of the card plate 107c in the unlocked state and reducing mechanical resistance. A guide slope 106c is provided at the right end of the slot 106a. The guide slope 106c adopts a smooth slope design with an optimized angle (e.g., 30°~45°) to guide the card plate 107c to a smooth transition, reduce wear, and ensure smooth unlocking. Figure 2 As shown, when the terminal connector 203 is connected to the interface module 100, the locking plate 107c is engaged in the slot 106a, with its front and rear ends abutting against the front and rear walls of the slot 106a, firmly fixing the rotating cylinder 105 and ensuring a stable electrical connection between the connector 203 and the connecting piece 102, preventing loosening due to vibration or external force. The guide slope 106c ensures that when the rotating cylinder 105 rotates, the locking plate 107c moves out of the slot 106a under the guidance of the slope, releasing the limiting fixation on the movable cylinder 104 and the rotating cylinder 105, and simultaneously allowing the locking plate 107c to return to the translation slot 106b; as Figure 3 As shown, at this time, the initial end of the card plate 107c is located at the rear end inside the translation slot 106b, the connection module 200 is separated from the interface module 100, and the internal structure of the interface module 100 returns to its initial state, preparing for the next connection.

[0040] More specifically, the movable cylinder 104 includes an outer cylinder 104a and an inner cylinder 104b, which are fixedly connected by a connecting block 104c to form a stable double-layer structure. The outer cylinder 104a is made of high-strength material, providing mechanical protection and structural support. A rotating cavity 104d is formed between the outer cylinder 104a and the inner cylinder 104b, providing a sealed space for the rotation of the rotating cylinder 105 to prevent dust or foreign objects from entering and affecting mechanical performance. The rotating cylinder 105 is rotatably connected within the rotating cavity 104d, and its material is wear-resistant metal or engineering plastic to ensure long-term stability. The rotating cylinder 105 has two through slots 105a arranged in a circular array on its upper and lower sides, facing the guide slope 106c. These through slots 105a are arc-shaped, limiting the rotation angle of the rotating cylinder 105 (e.g., 40°–65°) to prevent excessive rotation and ensure sufficient rotation angle for the clamping plate 107c to move out of the clamping slot 106a, while also ensuring the sliding connection of the connecting block 104c. The two connecting blocks 104c are slidably connected within the two through slots 105a. The connecting blocks 104c are made of high-strength material with a smooth surface to reduce friction, ensuring the synchronous movement and precise rotation of the movable cylinder 104 and the rotating cylinder 105.

[0041] Furthermore, the front end of the rotating drum 105 extends through the rotating cavity 104d and is fixedly connected to a knob 105b. The knob 105b is ergonomically designed with a textured surface to increase friction, facilitating user rotation. Its compact design also meets the needs of miniaturized equipment. The rear end of the rotating drum 105 also extends through the rotating cavity 104d and into the connecting cavity 101a, where it is connected to the positioning component 107 to ensure precise coordination between the rotational action and the locking mechanism. A bending groove 104d1 is provided at the rear end of the rotating cavity 104d, providing installation space for the torsion spring 109 and optimizing its force distribution. The torsion spring 109 is fixedly connected to the outer wall of the rear side of the inner cylinder 104b. The torsion spring 109 is made of a highly elastic material, and its rear end is fixedly connected to the front wall inside the rotating drum 105. The torsion spring 109 generates a restoring force when the drum 105 rotates, ensuring that the drum 105 automatically returns to its initial position after the knob 105b is released. At the same time, the rotation angle is limited by the curvature of the through groove 105a to prevent excessive rotation from causing mechanism failure. This design improves the automation and reliability of the operation.

[0042] Furthermore, an annular groove 105c is formed on the outer surface of the rear end of the rotating cylinder 105, and an annular ring 104a1 is fixedly installed on the rear side of the inner wall of the outer cylinder 104a, with the annular ring 104a1 engaging within the annular groove 105c. The annular groove 105c and the annular ring 104a1 are precision-machined to ensure smooth rotation of the rotating cylinder 105 within the rotating cavity 104d, while also allowing the movable cylinder 104 to move horizontally back and forth, driving the rotating cylinder 105 to move synchronously, thus enhancing the overall structural coordination. This design ensures both the rotational freedom of the rotating cylinder 105 and the linkage stability between the movable cylinder 104 and the rotating cylinder 105.

[0043] Furthermore, the connecting hole 108 includes a first slot 108a and a second slot 108b that are interconnected. The first slot 108a is located at the front end of the second slot 108b, and its internal diameter is larger than that of the second slot 108b, ensuring precise fitting between the insulating part 202 and the connector 203. The first slot 108a accommodates the insulating part 202, providing electrical insulation and mechanical positioning; the second slot 108b engages the connector 203, ensuring stable electrical contact. The insulating part 202 is inserted into the first slot 108a, with its rear wall abutting against the rear wall of the first slot 108a, pushing the movable cylinder 104 and the rotating cylinder 105 backward; the connector 203 is engaged in the second slot 108b, penetrating the connecting hole 108 and contacting the connecting piece 102. This hierarchical design improves the alignment accuracy and connection reliability of the insertion, while also facilitating the operation of the locking mechanism.

[0044] The working principle of this device is as follows:

[0045] During installation, the operator inserts the connector 203 and the insulating part 202 into the connecting hole 108 and pushes them into the housing 101. The rear wall of the insulating part 202 abuts against the rear wall of the first slot 108a, causing the movable cylinder 104 and the rotating cylinder 105 to move into the connecting cavity 101a. When the rear end of the connector 203 abuts against the contact point of the connecting piece 102, the retaining plate 107c moves from the translation groove 106b into the retaining slot 106a. Because the retaining slot 1... The misalignment design of 06a and translation slot 106b allows the elastic force of the telescopic spring 107a to push the locking plate 107c deep into the slot 106a, limiting and locking the rotating cylinder 105 and the movable cylinder 104. At this time, the pull-back force generated by the stretching of the return spring 103 is offset by the locking effect of the locking plate 107c, ensuring that the rotating cylinder 105 and the movable cylinder 104 are stable in this position, realizing a reliable electrical connection between the connector 203 and the connecting piece 102, and meeting the high bandwidth transmission requirements of 5G.

[0046] During disassembly, the operator rotates knob 105b, causing the rotating drum 105 to deflect. The guide ramp 106c pushes the clamping plate 107c upward, disengaging it from the limit of the clamping slot 106a. Simultaneously, the torsion spring 109 generates a reverse rebound force. Under the pulling force of the return spring 103, the movable cylinder 104 moves forward. The torsion spring 109 causes the rotating drum 105 to rotate and reset. The clamping plate 107c moves back along the outer surface of the rotating drum 105 to its initial position in the translation slot 106b, allowing the connecting module 200 to be easily pulled out. This design, through automatic reset and tactile feedback, improves operational convenience and reliability, making it suitable for high-requirement scenarios such as 5G base stations and IoT devices.

[0047] This embodiment, through precise mechanical structure design, combined with the reset spring 103, torsion spring 109 and positioning component 107, achieves rapid insertion and removal, high reliability and environmental adaptability, overcoming the shortcomings of traditional bolt fixing operation being cumbersome and spring clips being prone to breakage and unstable under vibration environment, significantly improving the performance of communication module interface terminals and user experience.
