Description

TECHNICAL FIELD

[0001] The utility model relates to radio frequency connector technical field, especially a NEX10 joint for durability test. BACKGROUND

[0002] In modern communication technology and equipment, the reliability and durability of radio frequency connectors are crucial. NEX10 joint, as a kind of connector widely used in high-frequency signal transmission, can provide efficient and stable electrical connection in communication systems. However, traditional NEX10 joints have performance degradation problems during long-term use, especially in frequent plugging test environments. Traditional NEX10 joints provide compression force through elastic protrusions to ensure stable plugging. However, the elastic protrusions are easily worn out and eventually fall off during high-strength plugging. The plugging life of the joint in this environment may only have a few hundred times, ultimately leading to poor joint connection or damage, resulting in significant economic losses and affecting the stability and reliability of the entire system.

[0003] Therefore, to meet the high durability requirements of connectors in plugging tests, a new joint design is needed. To solve the above problems, we propose a NEX10 joint for durability testing. SUMMARY

[0004] The utility model aims at providing a NEX10 joint for durability testing to solve the problem of existing NEX10 joints in frequent plugging test environments, where elastic protrusions are easily worn out and eventually fall off, resulting in short plugging life, economic losses, and insufficient reliability.

[0005] To solve the above technical problems, the utility model provides a NEX10 joint for durability testing, including male joint;The male joint is in the shape of a ring-shaped cylinder, which includes a first ring-shaped insertion cylinder and a second ring-shaped insertion cylinder set inside the first ring-shaped insertion cylinder. The first ring-shaped insertion cylinder and the second ring-shaped insertion cylinder are concentric, and the second ring-shaped insertion cylinder extends from the first ring-shaped insertion cylinder port.

[0006] The female joint is also in the shape of a ring-shaped straight cylinder, and the male joint is inserted into the female joint. The inner diameter of the female joint is equal to the outer diameter of the first ring-shaped insertion cylinder. The female joint includes a connection cavity, an insertion cavity set at the bottom of the connection cavity, and a connection thread set on the outer wall of the female joint.

[0007] The rotating sleeve is set outside the male joint and is used to connect the male joint and the female joint. The rotating sleeve cooperates with the connection thread.

[0008] Preferably, the rotating sleeve comprises a plug-in passage and a sealing ring arranged at one side of the plug-in passage.

[0009] The rotating sleeve is fixedly installed on the outer surface of the male connector by a clamping block.

[0010] Preferably, the first annular plug-in sleeve and the second annular plug-in sleeve are integrated, the second annular plug-in sleeve is fixedly connected to the inner wall of the first annular plug-in sleeve, and a fitting gap of 0.1mm to 0.2mm exists between the first annular plug-in sleeve and the second annular plug-in sleeve.

[0011] Preferably, the second annular plug-in sleeve is provided with a plurality of slits parallel to the barrel body from the barrel mouth of the second annular plug-in sleeve along the barrel body, so that the barrel mouth can be moderately contracted under the action of an external force, thereby facilitating the insertion of the second annular plug-in sleeve into the plug-in cavity.

[0012] Preferably, the first annular plug-in sleeve and the second annular plug-in sleeve are inserted into the plug-in cavity, the outer wall of the first annular plug-in sleeve is a flat straight surface, and the fitting force of the insertion relies on the contraction of the barrel mouth of the second annular plug-in sleeve.

[0013] Compared with the prior art, the NEX10 connector for durability test of the utility model uses an integrated double-ring plug-in sleeve structure to replace the traditional elastic protrusions, the contact surface with the plug-in cavity is two planes, the compression force is provided by the second annular plug-in sleeve with certain contractility, and finally the external rotating sleeve is used for thread connection and locking. This structure reduces the dependence on the elastic protrusions, thereby reducing wear and fatigue, improving the durability of the connector, and being very suitable for test environments that need frequent plug-in and plug-out. The plug-in and plug-out life is improved from several hundred times to tens of thousands of times, the test cost is significantly reduced, and the stability and reliability of the test system are greatly improved.
