Description

Technical Field

[0001] This utility model relates to the field of audio cables, and in particular to an XLR head audio cable. Background Technology

[0002] In the field of audio transmission, three-core XLR audio cables are widely used for signal connections between various professional audio equipment, such as recording studios, stage performances, and radio stations. Currently, the reset mechanism of the snap-in button in commonly available three-core XLR cables has a serious flaw. The traditional method uses a flexible, grounded core for reset, with the snap-in button's interior tightly pressed against the grounded core. When the user presses and releases the button, the grounded core resets due to its own elasticity, thus ejecting the button.

[0003] However, in actual frequent use, the grounding core is subjected to alternating stress from pressing and rebounding for extended periods, making it highly susceptible to fatigue. Once the grounding core fatigues, its elasticity decreases significantly, rendering it unable to provide sufficient spring force to securely eject and reset the locking button. This not only affects the ease of XLR connector connection but may also lead to loose connections, resulting in audio signal transmission interruptions, noise interference, and other problems. This severely reduces the user experience and operational efficiency of audio equipment, necessitating improvements to meet the reliability and stability requirements of professional audio transmission. Utility Model Content

[0004] To improve the stability of the audio cable's snap-on button reset, this utility model provides an XLR head audio cable.

[0005] This utility model provides a technical solution that adopts the following approach:

[0006] An XLR head audio cable includes a cable body and an XLR head located at one end of the cable body. The XLR head is movably connected to a button. The side wall of the XLR head has a through hole for the button to move. The inner side of the XLR head has an elastic part. The elastic part is annular and its peripheral wall fits against the inner circumference of the XLR head. The outer ring of the elastic part abuts against the inner side of the button. The XLR head also has a limiting member inside to restrict the movement of the elastic part along the length direction of the XLR head.

[0007] The elastic part is ring-shaped and independent of the signal transmission line. When the button is pressed, the elastic part deforms under force. After the user releases the button, the limiting component restricts the single direction of movement of the elastic part, causing it to recover its deformation and thus spring the button back to its original position. The elastic part provides a reliable and uniform reset force for the button, avoiding the impact of signal component fatigue on reset. Furthermore, when the elastic part is compressed, the side wall of the XLR head restricts the outward movement of the elastic part. When the button is released, the inner side wall of the XLR head assists in applying force, making the elastic part recover its deformation more sensitively. The ring-shaped elastic part avoids the three pins inserted into the XLR head, resulting in a more reasonable overall spatial layout.

[0008] Preferably, the side of the elastic part near the button is a plane, and the inner side of the button is a plane that fits against the plane of the elastic part.

[0009] Both the elastic element and the button have flat surfaces on the side that abuts against each other, allowing the contact surfaces of the elastic element and the button to fit tightly together. The elastic element is set around the circumference of the XLR head, and the length direction of the button is consistent with the length direction of the XLR head. The planes of the button and the XLR head are set perpendicular to each other. The double-plane setting makes the contact between the elastic element and the button more stable, making it less likely for the elastic element and the button to misalign.

[0010] Preferably, the elastic part is a ring formed by metal sheets.

[0011] The metal plate can fit more tightly against the inner wall of the XLR head and is less likely to slip inside the XLR head.

[0012] Preferably, the elastic part is an open ring, and the open side and the planar side of the elastic part are arranged opposite each other on both sides of the axis of the elastic part.

[0013] Open-ended rings are easier to install than closed-ended rings.

[0014] Preferably, the elastic part is a closed ring.

[0015] Compared to open-ended rings, closed-ended rings are more securely installed inside the XLR connector.

[0016] Preferably, a connecting portion for strengthening the connection is provided between the planar segment and the arc-shaped segment of the elastic part.

[0017] In this embodiment, the connecting part is a chamfered structure reinforced by welding between the planar segment and the arc segment, so that the connecting part and the elastic part are integral, making the connection between the planar segment and the arc segment less prone to breakage when the planar segment of the elastic element is subjected to pressure and the arc segment deforms.

[0018] Preferably, the button is integrally connected to a guide post, the bottom wall of the guide post is flush with the flat section of the button, and the interior of the XLR head is provided with a guide cylinder for the guide post to slide into.

[0019] The guide post and guide cylinder work together to reinforce the connection between the button and the XLR head, while also assisting the button to slide, making the button's movement smoother. At the same time, they prevent the button from moving in directions other than the intended one, reducing the chance of the button squeezing the elastic part in other directions.

[0020] In summary, this utility model has the following beneficial technical effects:

[0021] The elastic part is ring-shaped and independent of the signal transmission line. When the button is pressed, the elastic part deforms under force. After the user releases the button, the limiting component restricts the single direction of movement of the elastic part, causing it to recover its deformation and thus spring the button back to its original position. The elastic part provides a reliable and uniform reset force for the button, avoiding the impact of signal component fatigue on reset. Furthermore, when the elastic part is compressed, the side wall of the XLR head restricts the outward movement of the elastic part. When the button is released, the inner side wall of the XLR head assists in applying force, making the elastic part recover its deformation more sensitively. The ring-shaped elastic part avoids the three pins inserted into the XLR head, resulting in a more reasonable overall spatial layout. Attached Figure Description

[0034] Open-ended rings are easier to install than closed-ended rings.

[0035] Reference Figure 1 as well as Figure 2 In this embodiment, the elastic part is a closed ring.

[0036] Compared to open-ended rings, closed-ended rings are more securely installed inside the XLR connector.

[0037] Reference Figure 1 as well as Figure 2 In this embodiment, a connecting portion for strengthening the connection is provided between the planar segment and the arc-shaped segment of the elastic part.

[0038] In this embodiment, the connecting part is a chamfered structure reinforced by welding between the planar segment and the arc segment, so that the connecting part and the elastic part are integral, making the connection between the planar segment and the arc segment less prone to breakage when the planar segment of the elastic element is subjected to pressure and the arc segment deforms.
