Description

Technical Field

[0001] The utility model belongs to the field of audio connectors, and in particular relates to an improved XLR connector. Background Art

[0002] In the field of audio transmission, especially in professional audio equipment and stage performance equipment, the stability and flexibility of the XLR adapter as the core component of connecting audio signals has always been the focus of technology research and development. The design of traditional XLR adapters often focuses on lossless signal transmission and physical durability, but with the advancement of technology and the evolution of market demand, the pursuit of convenience, miniaturization and cost efficiency is increasing.

[0003] In this context, the applicant has previously successfully submitted and published a utility model patent with application number 202122504941.7, which discloses an audio plug that can be rotated and adjusted in angle. By integrating a bushing structure inside the positive plug or the negative plug, the pin and the inner core are precisely positioned and firmly connected, thereby ensuring the reliability of signal transmission at various use angles. However, with market feedback and in-depth exploration of technology, the applicant realized that the use of bushings in existing designs effectively enhanced the stability of the connection, but also increased the complexity of production and manufacturing, occupied unnecessary space, and increased costs.

[0004] In view of this, the applicant set out to optimize and upgrade the original design, with the goal of maintaining the original technical advantages while eliminating the bushing through innovative structural design without sacrificing the effective positioning and stable connection performance between the insert and the inner core, so as to simplify the assembly process, reduce product size and reduce costs.

[0005] Therefore, based on some of the above prior art situations, the present application has been further designed and improved. Utility Model Content

[0006] The utility model provides an improved Canon conversion head, including a connecting structure, and a joint structure assembled at both ends of the connecting structure, wherein a core is assembled in the joint structure. An assembly part for assembling the core is arranged in the joint structure, and a limiting convex ring is arranged on one side of the assembly part, and a radial limiting surface a and a first axial limiting surface b are arranged on the limiting convex ring; a second axial limiting surface c is arranged on the other side of the assembly part. A radial matching surface a' that matches the radial limiting surface and an axial matching surface b' that matches the first axial limiting surface are arranged on the core. When the connecting structure and the joint structure are assembled, the end face of the end head of the connecting structure abuts against the second axial limiting surface c, and the end face of the end head extends inwardly to form an end face d, which exceeds the second axial limiting surface c, so that the axial movement of the core is limited between the first axial limiting surface b and the end face d. This design utilizes the coordination of the radial limiting surface a, the first axial limiting surface b, the second axial limiting surface c, the radial mating surface a', and the axial mating surface b' to achieve the positioning and assembly of the joint structure. Compared with the original positioning scheme, the bushing is eliminated, the length of the joint structure is shortened, and the production cost is reduced.

[0007] Preferably, a limiting groove is provided on the end of the connecting structural member, and a clamping groove is provided on the joint structural member. A limiting clamping spring is installed in the clamping groove, and the limiting clamping spring extends into the limiting groove.

[0029] Reference Figures 1 to 7 , an improved XLR converter, comprising a connection structure 10, and a joint structure 20 assembled at both ends of the connection structure 10, wherein a core 30 is assembled in the joint structure 20. An assembly part for assembling the core 30 is provided in the joint structure 20, and a limiting convex ring 21 is provided on one side of the assembly part, and a radial limiting surface a and a first axial limiting surface b are provided on the limiting convex ring 21; and a second axial limiting surface c is provided on the other side of the assembly part. The core 30 is provided with a radial mating surface a' that matches the radial limiting surface, and an axial mating surface b' that matches the first axial limiting surface. When the connection structure 10 and the joint structure 20 are assembled, the end face of the end of the connection structure 10 abuts against the second axial limiting surface c, and the end face of the end extends inwardly to form an end face d, which exceeds the second axial limiting surface c, so that the axial movement of the core 30 is limited between the first axial limiting surface b and the end face d. The utility model forms a precise three-dimensional positioning structure through the cooperation of the radial limiting surface a, the first axial limiting surface b, the second axial limiting surface c, the radial matching surface a' and the axial matching surface b', so as to reliably and stably assemble the joint structure 20 on the connection structure 10.

[0030] In the utility model, the improved XLR converter adopts a standard male or female interface, and the connector components 20 on both sides of the connecting component 10 can be a male connector or a female connector to meet the diverse connection requirements between different audio devices.

[0031] Furthermore, a limiting groove 11 is provided on the end of the connecting structure 10, and a clamping groove 22 is provided on the joint structure 20. A limiting clamping spring 23 is installed in the clamping groove 22, and the limiting clamping spring 23 extends into the limiting groove 11. The assembly of the limiting clamping spring 23 and the limiting groove 11 can limit the axial movement of the joint structure 20. A plurality of circumferential limiting grooves 24 are provided on the assembly part, and a circumferential matching protrusion 31 matching with the circumferential limiting grooves 24 is provided on the core part 30. The combined design of the above structure not only provides an additional axial fixing mechanism for the joint structure 20, but also simplifies the assembly process, improves the assembly efficiency, and at the same time enhances the durability and reliability of the structure, and reduces the loosening problem that may occur in long-term use.

[0032] Furthermore, a limiting slide groove 12 is provided on the side of the end of the connecting structure 10, and a limiting slider 25 is provided on the inner wall of the corresponding limiting slide groove 12 of the joint structure 20. The rotation range α of the limiting slider 25 in the limiting slide groove 12 is 0°~285°. This design enables the joint structure 20 to rotate 0°~285° around the axis, which facilitates the joint structure 20 to connect devices with different interface directions. An assembly groove 13 is provided on the side of the end of the connecting structure 10, and a damping ring 14 is installed in the assembly groove 13. When the connecting structure 10 and the joint structure 20 are assembled, the damping ring 14 abuts against the inner wall of the joint structure 20. The dynamic matching mechanism of the limit slide 12 and the limit slider 25 not only gives the joint structure 20 a flexible rotation capability to adapt to the changing installation environment and angle requirements, but also ensures controllability during use by limiting the rotation range of the limit slider 25, avoiding structural damage or connection failure caused by excessive rotation. The integration of the damping ring 14 further optimizes the user experience. By adding appropriate rotation resistance, the user can feel clear operational feedback when adjusting the direction of the joint, while also reducing the internal structural impact that may be caused by rapid rotation, extending the service life of the product.

[0033] In the present invention, the central axis of the two ends of the connecting structure 10 has an angle β. The specific angle design of the improved XLR converter breaks the limitation that the traditional converter can only be used in a single plane, realizes flexible docking in the spatial dimension, and meets the demand for efficient interconnection between devices in a complex layout environment. This shows significant advantages in scenes such as stage sound arrangement and multi-angle video surveillance system construction, and greatly expands its application scope. Preferably, the angle β=90°, that is, the joint structures 20 on both sides of the connecting structure 10 are perpendicular to each other, and this structural design can be applied to mainstream usage scenarios.

[0034] Compared with the prior art, the utility model has the following beneficial effects: the design utilizes the radial limiting surface a, the first axial limiting surface b, the second axial limiting surface c, the radial mating surface a', and the axial mating surface b' to achieve the positioning and assembly of the joint structure 20. Compared with the original positioning scheme, the bushing is eliminated, the length of the joint structure 20 is shortened, and the production cost is reduced.

[0035] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention shall be based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field shall fall within the protection scope of the present invention.
