[0002] With the rapid development of aerospace, industrial automation, 5G communication, and high-end instrumentation, electronic devices are placing increasingly stringent performance requirements on connectors. As a core component for achieving electrical connections, the reliability of connectors directly affects the signal transmission quality and operational stability of the system.

[0003] However, existing connectors cannot be easily adjusted when the plug and socket are mated, even in the event of a misalignment, thus failing to guarantee good transmission performance. Utility Model Content

[0005] The biaxial floating connector structure includes an outer conductor, a dielectric body, and an inner conductor connected coaxially. The outer conductor is provided with a plug end and a crimp end. A connector is movably connected inside the outer conductor and at the plug end. Both ends of the circumferential surface of the connector are integrally formed with limiting portions.

[0006] A limiting groove is formed on the outer surface of the outer conductor, and an elastic retaining ring is provided on the limiting groove.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] The biaxial floating connector structure includes an outer conductor 11, a dielectric body 17, and an inner conductor 18 connected coaxially. The outer conductor 11 is provided with a plug end and a crimp end 12. A connector 13 is movably connected inside the outer conductor 11 and located at the plug end. Both ends of the circumferential surface of the connector 13 are integrally formed with limiting portions 135. The inner wall of the outer conductor 11 is provided with a receiving groove to accommodate the limiting portions 135, so that the connector 13 can be radially offset relative to the outer conductor 11.

[0020] A limiting groove is formed on the outer surface of the outer conductor 11, and an elastic retaining ring 15 is provided on the limiting groove. A spring 14 is provided in the limiting groove and above the elastic retaining ring 15, so that the outer conductor 11 moves axially relative to the elastic retaining ring 15.

[0021] Specifically, when the connector's mating ends are connected, a certain lateral misalignment may occur due to manufacturing errors or installation deviations. In this case, the connector 13 slides in the receiving groove through the limiting part 135, allowing the connector to slightly deflect or offset radially relative to the outer conductor 11, avoiding poor contact or component damage caused by rigid mating. At the same time, the presence of the limiting part 135 also prevents the connector 13 from detaching from the outer conductor 11, ensuring structural stability. In the axial direction, there is an elastic space provided by the spring 14 between the outer conductor 11 and the elastic retaining ring 15, which snaps the elastic retaining ring 15 into the installation position. When the mating end is subjected to axial push-pull force, the outer conductor 11 can move axially relative to the elastic retaining ring 15 under the action of the spring 14. The spring 14 plays a buffering role, ensuring good contact pressure and avoiding structural damage caused by excessive axial force. This axial floating capability enhances the connector's adaptability to different length tolerances and improves the mating life.

[0022] The radial and axial floating mechanisms work together to give the connector a certain degree of fault tolerance in three-dimensional space. Radial offset compensates for lateral deviation, and axial movement compensates for longitudinal displacement, jointly ensuring the reliability of the connection. This can significantly improve the reliability of the connection and reduce the risk of signal attenuation or disconnection caused by mechanical stress.

[0023] In one embodiment, the connector 13 includes a second outer conductor 131, a second dielectric body 133, and a second inner conductor 132, all coaxially distributed. The limiting part 135 is integrally formed at both ends of the circumferential surface of the second outer conductor 131. The second inner conductor 132 is used for signal transmission, the second dielectric body 133 serves as insulation support and ensures impedance matching, and the second outer conductor 131 provides shielding and mechanical support, with limiting parts 135 at both ends. The entire connector 13 exists as a floating intermediate conductive module. During connection, the second inner conductor 132 of the connector 13 mates with the corresponding inner conductor in other connectors, and the second outer conductor 131 forms a continuous shielding layer with the first outer conductor 11. The second dielectric body 133 ensures the consistency of the characteristic impedance of the entire connection segment and avoids signal reflection. The connector 13 can undergo angular deflection or lateral movement within the first outer conductor 11.

[0024] In one embodiment, multiple sets of notches 134 arranged in a ring array are provided at both ends of the outer conductor 2 131. The notches 134 divide the overall structure of the outer conductor 2 131 into multiple "elastic claws" or "elastic petals". The elastic petals can generate a certain pre-tightening force during the insertion process, so that the outer conductor 2 131 fits more tightly into the receiving groove of the inner wall of the outer conductor 11.

[0025] In one embodiment, the elastic retaining ring 15 has a groove for deformation, and a washer 16 is provided between the spring 14 and the elastic retaining ring 15. The groove allows the elastic retaining ring 15 to expand outward and contract inward, facilitating locking and releasing. In the initial state, the elastic retaining ring 15 is in a naturally open state, with a diameter larger than the inner diameter of the through hole at the installation position. During the process of inserting the outer conductor 11 into the through hole, an external force is first applied to the elastic retaining ring 15, causing it to contract inward, reducing its diameter and entering the through hole. When the elastic retaining ring 15 enters the through hole and loses external pressure, it resets under the action of elastic restoring force, and its diameter increases. At this time, the retaining ring is tightly engaged with the inner wall of the through hole, thus allowing the outer conductor 11 to be engaged and fixed in the through hole. The washer 16 can effectively prevent the spring 14 from getting stuck in the groove.

[0026] In one embodiment, both ends of the inner conductor 132 are provided with connecting grooves 1321, and the top of the inner conductor 18 is integrally formed with a center pin. The center pin extends into the connecting groove 1321, and the connecting groove 1321 is used to cooperate with the center pin to realize electrical connection. When the connector deflects, the circumferential surface of the center pin has a constant contact with the connecting groove 1321 of the connector 13, so that the contact resistance remains unchanged when the connector floats, and at the same time, the basic consistency of electrical performance is ensured when floating.

[0027] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
