[0006] As a preferred technical solution, the end of the sheath body facing away from the groove is also provided with a through-hole gap that communicates with the wire harness through-hole.

[0007] As a preferred technical solution, two positioning grooves are provided, and they are symmetrically arranged about the center line of the sheath body.

[0008] As a preferred technical solution, the annular support is located at the center of the sheath body, and the wire harness through hole is opened at the center of the annular support and is coaxial with the axis of the sheath body.

[0009] As a preferred technical solution, one end of the sheath body is an arc-shaped surface and the other end is a flat surface, with grooves formed on the arc-shaped surface to create an arc-shaped groove.

[0010] This utility model also provides an acoustic package, including a wire harness sheath and an acoustic package upper shell. The acoustic package upper shell has a notch 1 and a notch 2 adapted to the annular support portion. The notch 1 and the notch 2 cause the edge of the acoustic package upper shell to form a positioning pin adapted to the positioning groove.

[0011] As a preferred technical solution, the top opening of the notch is larger than the bottom opening, and the bottom opening is smaller than the diameter of the annular support.

[0012] As a preferred technical solution, the positioning groove and the positioning pin are interference fit.

[0013] As a preferred technical solution, the through-hole gap is located inside the bottom opening of the notch.

[0014] This utility model also provides an air suspension air supply unit, including the above-mentioned acoustic package.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) In this utility model, a positioning groove adapted to the opponent is provided at the other end of the sheath body, and the positioning groove provides a limit for the opponent, thereby reducing the risk of the sheath body falling off the opponent.

[0017] (2) In this utility model, the pre-hanging of the wire harness can be achieved by setting the wire harness through hole and the gap between the through hole.

[0018] (3) In this utility model, by setting a positioning pin on the upper shell of the acoustic package that is compatible with the positioning groove, the stability of the connection between the upper shell of the acoustic package and the sheath body is improved, thereby enabling the pre-hanging of the acoustic package or the sheath body.

[0019] (4) In this utility model, by making the top opening of the notch one larger than the bottom opening and the bottom opening smaller than the diameter of the annular support part, the annular support part can be prevented from being squeezed into the notch one and coming out from the bottom of the notch one, thereby improving the stability of the connection between the sheath body and the acoustic package.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] Example 1

[0032] See Figure 4 , Figure 5 A wire harness sheath includes a sheath body 1 with an annular support portion 11. In this embodiment, the annular support portion 11 is located at the center of the sheath body 1. A wire harness through hole 14 is formed in the annular support portion 11, penetrating the sheath body 1. In this embodiment, the wire harness through hole 14 is formed at the center of the annular support portion 11 and is coaxial with the axis of the sheath body 1. The wire harness through hole 14 is used to install the wire harness. A groove 12 is formed on one end of the sheath body 1 along its circumference, located outside the annular support portion 11. One end of the sheath body 1 is an arc-shaped surface, and the other end is a flat surface. The groove 12 is formed on the arc-shaped surface and forms an arc-shaped groove. A positioning groove 13 is formed on the other end of the sheath body 1 to fit a matching component. The positioning groove 13 can provide a limit for the matching component, thereby reducing the risk of the sheath body 1 falling off the matching component.

[0033] The sheath body 1 includes an arc-shaped segment and a rectangular segment, which are fixedly connected or integrally formed. The arc-shaped segment has an arc-shaped surface, and the end face of the rectangular segment opposite to the arc-shaped segment is a plane. In this embodiment, the axial direction of the wire harness through-hole 14 is taken as the thickness direction of the sheath body 1. (Refer to...) Figure 6 The arc-shaped groove is located at the middle of the two end faces of the sheath body 1 in the thickness direction.

[0034] See Figure 5 To facilitate wire harness assembly, the sheath body 1 is provided with a through hole gap 15 at one end away from the groove 12, which communicates with the wire harness through hole 14. The through hole gap 15 is a gap that penetrates through the thickness direction of the sheath body 1. Its front end face is flush with the front end face of the sheath body 1, and its rear end face is flush with the rear end face of the sheath body 1. In this embodiment, the front end face refers to the end face in the axial direction of the wire harness through hole 14. Since the sheath body 1 is made of rubber and has a certain elasticity, the wire harness can enter the wire harness through hole 14 through the through hole gap 15, thereby facilitating the assembly of the wire harness.

[0035] See Figure 5 , Figure 7 In order to improve the connection effect between the connector and the sheath body 1, in this embodiment, two positioning grooves 13 are provided. The two positioning grooves 13 are symmetrically arranged about the center line of the through hole gap 15. The two positioning grooves 13 are fixed with the mating structure on the connector, which further reduces the risk of the wire harness sheath falling off the connector.

[0036] In this embodiment, the groove 12 is connected to the two positioning grooves 13, which facilitates the processing of the sheath body 1.

[0037] Example 2

[0038] See Figure 8 , Figure 9 The difference between this embodiment and Embodiment 1 is that it provides an acoustic package including the wire harness sheath in Embodiment 1. The acoustic package also includes an upper acoustic package shell 2 and a lower acoustic package shell (not shown in the figure). The upper acoustic package shell 2 and the lower acoustic package shell can be fixed together by bolts. The upper acoustic package shell 2 is a pair of parts. The upper acoustic package shell 2 and the wire harness sheath are detachably fixed. Both the wire harness sheath and the upper acoustic package shell 2 are provided with a pre-hanging structure. The pre-hanging structure on the wire harness sheath is the annular support part 11, the groove 12, and the positioning groove 13 in Embodiment 1. The acoustic package shell 2 is provided with a notch 1 21 and a notch 22 that are adapted to the annular support part 11. The notch 1 21 and the notch 22 cause the edge of the upper acoustic package shell 2 to form a positioning pin 23 that is adapted to the positioning groove 13. In this embodiment, a total of two positioning pins 23 are provided. The two positioning pins 23 are symmetrically arranged about the center line of the sheath body 1.

[0039] See Figure 9To improve the limiting effect of notches 1 21 and 22 on the annular support 11, the top opening of notch 1 21 is larger than the bottom opening of notch 1 21, and the bottom opening is smaller than the diameter of the annular support 11. The top opening of notch 1 21 can be slightly larger than or the same as the diameter of the wire harness. After the annular support 11 is squeezed into notch 1 21, it is difficult to come out from the bottom of notch 1 21. Notch 1 21 is roughly circular. Notch 22 can be circular, rectangular or other irregular structure. The through hole gap 15 is located in the bottom opening of notch 1 21. It should be noted that in actual use, the acoustic package is placed horizontally, so the top opening of notch 1 21 is located below the plane where the top of the arc section of the wire harness sheath is located, and is set close to the top of the arc section of the wire harness sheath.

[0040] In this embodiment, in order to ensure the tightness of the positioning groove 13 and the positioning pin 23, the positioning groove 13 and the positioning pin 23 are interference fit. The end of the positioning pin 23 may also be provided with a triangular buckle. Since the sheath body 1 has a certain elasticity, the circumferential edge of the positioning groove 13 also has a certain elasticity. The buckle can pass through the positioning groove 13 in one direction. The buckle can provide a limit for the sheath body 1 and prevent it from coming out of the positioning groove 13 after passing through it.

[0041] Instructions for use: Move the sheath body 1 toward the notch on the hand piece and secure the sheath body 1 to the hand piece. The positioning groove 13 and the positioning pin 23 can be interference-fitted or fixedly connected. The annular support part 11 is squeezed into the notch 21.

[0042] When assembling the acoustic package, first insert the wire harness through the through-hole gap 15 into the wire harness through-hole 14, and then snap the sheath body 1 into the upper shell 2 of the acoustic package.

[0043] Example 3

[0044] The difference between this embodiment and embodiment 2 is that an air suspension air supply unit including the acoustic package in embodiment 2 is provided.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
