BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a cross-sectional view showing an audio connector according to an embodiment of the present invention when a tightening portion is not clamped to a wire clamping portion. Referring to FIG. 1 , the audio connector 100 of the present embodiment includes a tubular body 110 , a center pin 120 , and a sleeve 130 . The tubular body 110 includes a wire clamping portion 112, a terminal clamping portion 114 and a connecting portion 116. The wire clamping portion 112 and the terminal clamping portion 114 are connected via a connecting portion 116. A plurality of first slits S12 extend toward the connecting portion 116 from a side of the wire clamping portion 112 away from the connecting portion 116. In other words, one end of the first slit S12 is an opening on a side of the wire clamping portion 112 away from the connecting portion 116, and the wire clamping portion 112 is divided into a plurality of lobes by the first slit S12. The center pin 120 is fixed in the tubular body 110 by the connecting portion 116 for commonly connecting an audio terminal 50 (shown in FIG. 3) with the terminal clamping portion 114. The sleeve 130 is movably sleeved outside the tubular body 110. In other words, the tubular body 110 extends into the sleeve 130 and the two are relatively movable along the same axis.

Figure 2 is a cross-sectional view of the audio connector of Figure 1 as the tightening portion clamps the wire gripping portion. Referring to FIG. 2, the sleeve 130 has a tightening portion 132. The tightening portion 132 is for tightening the portion of the wire holding portion 112 having the first slit S12 and narrowing the first slit S12.

The inner diameter of the wire clamping portion 112 is equal to or larger than the outer diameter of the wire 30 in a state where it is not subjected to an external force. Therefore, the wire 30 can protrude into the wire clamping portion 112. After the wires in the wire 30 are soldered or otherwise joined to the center pin 120, the sleeve 130 can be moved to tighten the wire clamping portion 112 with the tightening portion 132. Due to the presence of the first slit S12, the first slit S12 is gradually narrowed during the tightening of the wire holding portion 112. As the first slit S12 is gradually reduced, the inner diameter of the wire holding portion 112 is also gradually reduced to be smaller than the outer diameter of the wire 30, whereby the wire 30 can be clamped without being loosened. It can be seen from the above that the audio connector 100 of the present embodiment can be firmly connected to the wire 30 without the need of a screw, thereby avoiding the damage that the screw may cause to the wire 30, and also eliminating the time and cost of preparation and assembly.

In this embodiment, the sleeve 130 and the tubular body 110 are screwed together, so that the user can change the position of the sleeve 130 on the tubular body 110 by rotating the sleeve 130, thereby controlling the wire clamping portion 112. For the clamping force of the wire 30. The tubular body 110 of the present embodiment is integrally formed, that is, the wire clamping portion 112, the terminal clamping portion 114 and the connecting portion 116 are inseparable, but in other embodiments the tubular body 110 may also be assembled by a plurality of components. Made. The tubular body 110 of the present embodiment may be electrically conductive, such as made of metal, and may be used for grounding. The center pin 120 of this embodiment can be electrically conductive, such as made of metal, for transmitting audio. When both the tubular body 110 and the center pin 120 are electrically conductive, an insulating member 140 may be disposed to insulate the center pin 120 from the tubular body 110. The material of the insulating member 140 may be teflon or other materials.

In this embodiment, the audio connector 100 further includes at least one backing ring 150 disposed between the insulating member 140 and the tubular body 110 for fixing the relative position of the insulating member 140 and the tubular body 110. This embodiment is exemplified by two backing rings 150, but the present creation is not limited thereto. For example, when assembling the audio connector 100, the insulating member 140 and the center pin 120 may be first placed into the tubular body 110, and the spacer ring 150 may be placed between the insulating member 140 and the tubular body 110. The material of the backing ring 150 is, for example, a material having a large surface frictional force, so that the insulating member 140 can be appropriately fixed in the tubular body 110 by friction. The backing ring 150 can be a complete one or a C-ring. In other embodiments, the tubular body 110, the insulating member 140, and the center pin 120 can be formed by two-shot injection molding without the use of the backing ring 150.

In this embodiment, when the sleeve 130 is sleeved outside the tubular body 110, the inner diameter R1 of the portion of the tightening portion 132 away from the connecting portion 116 is smaller than the inner diameter R2 of the portion of the tightening portion 132 close to the connecting portion 116. Therefore, when the tightening portion 132 moves in the direction of the connecting portion 116, the portion of the inner diameter R1 also moves in the direction of the wire holding portion 112, and the wire holding portion 112 is tightened. Further, the outer diameter R3 of the portion of the wire holding portion 112 of the present embodiment remote from the connecting portion 116 is, for example, smaller than the outer diameter R4 of the portion of the wire holding portion 112 close to the connecting portion 116. Thereby, the wire clamping portion 112 and the tightening portion 132 are in contact with each other with a sloped surface, which provides a better experience. Additionally, the surface of the sleeve 130 has, for example, a groove, and an identification ring 134 can be disposed within the groove. With the identification ring 134 of different colors, the user can know that the audio connector 100 currently in use is for the left channel, the right channel or other sources. Furthermore, the grooves can be painted in a different color than the identification ring 134. Thus, as long as the identification ring 134 is selectively disposed or the identification ring 134 is not disposed, it is possible to distinguish which audio source 100 is currently used, depending on the color of the groove or the color of the identification ring 134.

In this embodiment, the side of the terminal clamping portion 114 away from the connecting portion 116 extends to the connecting portion 116 with a plurality of second slits S14. 3 is a schematic diagram of the audio connector of FIG. 2 connected to an audio terminal. Referring to FIGS. 2 and 3, the inner diameter of the terminal holding portion 114 is slightly smaller than the outer diameter of the audio terminal 50 when it is not subjected to an external force. Due to the presence of the second slit S14, when the terminal clamping portion 114 is connected to the audio terminal 50, the second slit S14 is gradually enlarged to enlarge the inner diameter of the terminal holding portion 114 to accommodate the audio terminal 50. Thereby, the terminal holding portion 114 can clamp the audio terminal 50 without being loosened.

In summary, the audio connector of the present invention has a slit in the line clamping portion, so that the inner diameter of the wire clamping portion is also reduced when the wire clamping portion is tightened by the tightening portion of the sleeve, thereby clamping the wire. This design replaces the conventional use of screws to lock the wire, which can prevent the wire from being damaged by the screw, thereby improving the reliability of the signal line. Moreover, it has the advantage of easy assembly and low cost.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the novel creation, and any person skilled in the art can make some changes without departing from the spirit and scope of the novel creation. Retouching, the scope of protection of this new creation is subject to the definition of the scope of the patent application attached.
