Description

Technical Field

[0001] This utility model relates to the field of radio frequency (RF) connection cable testing technology, and in particular to an RF connection cable for rapid testing. Background Technology

[0002] Radio frequency (RF) cables are specifically designed for transmitting radio frequency (RF) signals and are widely used in wireless communication, broadcasting, radar, satellite communication, and electronic testing. Their core function is to achieve low-loss, interference-resistant transmission of high-frequency signals while maintaining signal integrity. To ensure the performance and consistency of electronic equipment, RF cables need to be tested. RF testing allows for the early detection of potential problems in the equipment, such as circuit design errors or material defects. If these problems are not identified and resolved in a timely manner, they may affect the normal operation and performance of the equipment. Therefore, RF testing ensures the stable performance of electronic equipment during the production process, avoiding batch-to-batch performance inconsistencies and thus maintaining product quality stability and reliability.

[0003] However, most RF cables currently use SMA connectors. During factory RF testing, the threads of the SMA connectors need to be manually tightened to connect with the SMA interface threads of the testing instrument before the RF cable can be tested. However, manually tightening SMA connectors is labor-intensive, resulting in significant manpower waste and low production and testing efficiency for RF cables. Utility Model Content

[0004] To address the technical problems of existing technologies, such as the large workload of manually twisting SMA connectors during RF testing, resulting in significant manpower waste and low production and testing efficiency of RF cables, this utility model provides the following technical solution.

[0005] This utility model discloses a rapid testing radio frequency (RF) connection cable, comprising an RF cable and connectors and IPEX terminals located at both ends of the RF cable. The connector has an SMA connector threaded portion on the side away from the RF cable, and an MCX connector cavity is provided inside the SMA connector threaded portion. The connector is axially connected to a beryllium bronze gold-plated power supply female pin that extends into the MCX connector cavity. The beryllium bronze gold-plated power supply female pin has a protective sleeve on its outer periphery that is fixedly connected to the connector.

[0006] As a further technical solution, the inner wall of the MCX connector cavity is provided with an MCX connector locking groove.

[0007] As a further technical solution, the MCX connector cavity is connected to a protective sleeve.

[0008] As a further technical solution, the inner wall of the MCX connector cavity is slidably or fixedly connected to the protective sleeve.

[0009] As a further technical solution, the protective sleeve has a limiting end with a diameter larger than the inner diameter of the MCX connector cavity at one end located outside the MCX connector cavity.

[0010] As a further technical solution, the protective sleeve is made of a self-lubricating material.

[0011] The beneficial effects of this utility model are as follows: The connector of this utility model has an SMA connector threaded portion and an MCX connector cavity located inside the SMA connector threaded portion. During factory testing, the MCX connector of the testing machine can be directly engaged with the MCX connector cavity for testing, eliminating the need to tighten the SMA thread, reducing manpower waste, and greatly improving the efficiency of RF connector production and testing. Furthermore, in practical applications, the SMA connector threaded portion can be used directly, making it more secure and less prone to loosening. Simultaneously, the MCX connector cavity is equipped with a protective sleeve and a protective sheath. The protective sleeve effectively protects the beryllium bronze gold-plated feed pin, preventing accidental contact damage, and the protective sheath prevents wear on the MCX connector cavity, allowing for quick connection with the MCX connector of the testing machine and ensuring the stability of the entire connector.

[0015] like Figure 1 As shown, the present invention provides a rapid testing radio frequency connection cable, including a radio frequency cable 2 and connectors 1 and IPEX terminals 3 located at both ends of the radio frequency cable 2. The radio frequency cable 2 and IPEX terminals 3 adopt existing technology, so they will not be described in detail.

[0016] like Figure 1 and Figure 2 As shown, in a preferred embodiment, the side of connector 1 away from the RF line 2 is provided with an SMA connector threaded portion 4. The SMA connector threaded portion 4 has the same thread structure as existing SMA connectors and can be used directly at the factory. The SMA connector threaded portion 4 has an MCX connector cavity 5 inside, which can be matched with existing MCX connectors and can be directly fastened to the MCX connector of the test instrument. Therefore, during factory testing, the MCX connector of the test machine can be directly fastened to the MCX connector cavity 5 for testing, without tightening the SMA thread, reducing manpower waste and greatly improving the efficiency of RF connection cable production and testing.

[0017] In a preferred embodiment, the inner wall of the MCX connector cavity 5 is provided with an MCX connector locking groove 6, which allows existing MCX connectors to be snapped into place. A beryllium bronze gold-plated feed female pin 7 is axially connected to the connector 1, extending into the MCX connector cavity 5. To prevent damage to the beryllium bronze gold-plated feed female pin 7 when the MCX connector on the testing machine is snapped into the MCX connector cavity 5, a protective sleeve 8 is provided on the outer periphery of the beryllium bronze gold-plated feed female pin 7, which is fixedly connected to the connector 1. The protective sleeve 8 protects the beryllium bronze gold-plated feed female pin 7 while facilitating connection testing of the RF cable 2 by the testing machine after the MCX connector is connected to the MCX connector cavity 5.

[0018] In a preferred embodiment, to prevent frictional damage to the inner wall of the MCX connector cavity 5 when the MCX connector of the testing machine is connected to the MCX connector cavity 5 during the testing process, a protective sleeve 9 is connected to the inner wall of the MCX connector cavity 5. The protective sleeve 9 is made of nylon material with self-lubricating properties. When the MCX connector is snapped into the MCX connector cavity 5, it rubs against the inner wall of the protective sleeve 9 and snaps into the MCX connector locking groove 6, without causing wear to the inner wall of the MCX connector cavity 5.

[0019] The protective sleeve 9 can be slidably connected to the inner wall of the MCX connector cavity 5 or fixedly connected. When the protective sleeve 9 is slidably connected to the MCX connector cavity 5, it can be removed after testing. When the protective sleeve 9 is fixedly connected to the inner wall of the MCX connector cavity 5, it does not need to be removed. One end of the protective sleeve 9 located on the outside of the MCX connector cavity 5 is provided with a limiting end 10 with a diameter larger than the inner diameter of the MCX connector cavity 5. The limiting end 10 can prevent the protective sleeve 9 from extending too deeply into the MCX connector cavity 5, ensuring that the MCX connector of the testing machine and the MCX connector locking groove 6 are properly engaged.

[0020] When this utility model is in use, during factory testing, the MCX connector of the testing machine can be directly snapped into the MCX connector cavity 5 of the connector 1, allowing for quick insertion and removal, thus enabling rapid testing of the RF connection cable without the need to tighten the SMA thread. This also prevents damage to the MCX connector cavity 5 and the beryllium bronze gold-plated power supply pin 7, reducing manpower waste and greatly improving the efficiency of RF connection cable production and testing.

[0021] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, various changes or equivalent substitutions can be made without departing from the concept of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
