[0029] To make the technical problems solved, technical solutions, and beneficial effects 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.

[0030] In the description of this utility model, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] like Figures 1 to 5 As shown, an embodiment of this utility model provides a wire harness connection device, including an elastic element 3, a first snap-fit ​​structure 4, a second snap-fit ​​structure 5, a plug 1, and a socket 2; the socket 2 includes a second housing and a connecting piece 7, and the first snap-fit ​​structure 4 is disposed in the second housing; the plug 1 includes a first housing and a spring pin 6, and the spring pin 6 is disposed in the first housing; one end of the elastic element 3 is connected to the first housing, and the other end is connected to the first snap-fit ​​structure 4; when the plug 1 is inserted into the socket 2, the spring pin 6 contacts the connecting piece 7, and the first snap-fit ​​structure 4 snaps into the second snap-fit ​​structure 5.

[0033] In this embodiment, the spring pin 6 is a common pogo pin, which is a spring-type probe formed by riveting and pre-compressing three basic components: a needle shaft, a spring, and a needle tube using precision instruments. It contains a precision spring structure. Current or signal transmission is achieved between the plug 1 and the socket 2 through the contact between the connecting piece 7 and the spring pin 6.

[0034] Reference Figure 5 After plug 1 and socket 2 are inserted, the first locking structure 4 and the second locking structure 5 maintain the insertion state of socket 2 and plug 1 during signal interaction or current transmission, preventing the ports from becoming loose due to external pulling, vibration, or accidental contact. This is particularly suitable for mobile devices or environments prone to interference. After insertion is completed, the first locking structure 4 and the second locking structure 5 disengage under the action of external force, thereby causing socket 2 and plug 1 to separate.

[0035] Reference Figure 3 In one embodiment, the second housing is provided with a receiving groove 21, and the connecting piece 7 is disposed on the bottom wall of the receiving groove 21; the first housing can be partially inserted into the receiving groove 21, and the first housing is provided with a through hole located on the side of the first housing near the bottom wall of the receiving groove 21, and the spring pin 6 is disposed in the through hole. In this embodiment, a part of the first housing is inserted into the receiving groove 21, and the other part is exposed, so that a person can hold the exposed first housing to remove the plug 1.

[0036] Reference Figure 1 and Figure 2 In one embodiment, the elastic element 3 is a compression spring, and the first engaging structure 4 is a ball bearing; a groove is provided on the second housing, forming the second engaging structure 5. In this embodiment, the ball bearing is fixedly connected to the compression spring. When the plug 1 and the socket 2 are plugged in, the ball bearing is subjected to the elastic force of the compression spring, and a portion of the ball bearing is engaged in the groove. Under external force, the ball bearing can disengage from the groove. Ideally, the shape of the groove matches the ball bearing, allowing a portion of the ball bearing to be perfectly engaged in the groove. However, due to cost and manufacturing difficulty limitations, more often, the groove is hemispherical, with the radius of the groove slightly larger than the radius of the ball bearing.

[0037] Reference Figure 2 In one embodiment, the first housing includes an injection-molded housing and a ring 13. The injection-molded housing includes a main body 11 and an insertion part 12. The insertion part 12 is connected to the main body 11 and is used to insert into the receiving groove 21. The insertion part 12 is provided with a blind hole, and the elastic element 3 is disposed in the blind hole. The ring 13 is sleeved on the insertion part 12. The ring 13 is provided with a limiting hole, which communicates with the blind hole. The diameter of the limiting hole is smaller than the diameter of the first snap-fit ​​structure 4.

[0038] In this embodiment, the ring 13 is made of metal and is tightly fitted onto the insertion part 12. The metal ring 13 has strong wear resistance. Both the limiting hole and the blind hole are round holes with their central axes coinciding. The diameter of the limiting hole is slightly larger than the diameter of the elastic element 3 to facilitate the installation of the elastic element 3.

[0039] In one embodiment, the inner wall of the limiting hole is curved, and the inner diameter of the limiting hole decreases in the direction away from the blind hole. When the plug 1 is inserted into the socket 2, the inner wall of the limiting hole is in contact with the outer surface of the first snap-fit ​​structure 4. In this embodiment, the diameter of the limiting hole gradually decreases in the direction away from the blind hole to accommodate the spherical ball. When the ball is inserted into the groove, the surface of the ball is in contact with the inner wall of the limiting hole. At this time, compared with the technical solution where the diameter of the limiting hole remains unchanged along its axis, the surface area of ​​the ball inserted into the groove is the largest.

[0040] Reference Figure 4In one embodiment, a first alignment groove 22 is provided on the second housing, and a second alignment groove 14 is provided on the first housing. The cross-sections of both the first alignment groove 22 and the second alignment groove 14 are triangular. When the plug 1 is inserted into the socket 2, one corner of the first alignment groove 22 faces one corner of the second alignment groove 14. In this embodiment, when the plug 1 is inserted into the socket 2, the operator observes and rotates the socket 2 appropriately so that the first alignment groove 22 and the second alignment groove 14 are opposite each other. At this time, the plug 1 is inserted into the socket 2 at this angle, which can directly engage the ball bearing in the groove.

[0041] In one embodiment, a marking groove 15 is provided on the surface of the first housing away from the second housing. The marking groove 15 includes an arc groove and arrow grooves at both ends of the arc groove. In this embodiment, the arc is circular, and the tips of the two arrow grooves are far away from the arc groove. When the plug 1 is inserted into the socket 2 but the ball bearing is not engaged in the groove, the marking groove 15 is used to remind the operator to rotate the plug 1 clockwise or counterclockwise so that the ball bearing is not engaged in the groove.

[0042] In one embodiment, the socket 2 further includes a PCB board disposed within the second housing. The connecting piece 7 is soldered onto the PCB board. The second housing has contact holes, and the connecting piece 7 is located within the contact holes. In this embodiment, the contact holes are used to house the connecting piece 7 and to limit its movement.

[0043] In other embodiments, the elastic element 3 is a compression spring, and the second locking structure 5 is a ball bearing; a ball groove is provided on the first housing, and the ball groove constitutes the first locking structure 4. In other embodiments, the positions of the ball bearing and the groove can be interchanged, and the ball bearing and the elastic element 3 can be placed on the socket 2, while the groove can be placed on the plug 1, which can also achieve temporary locking of the plug 1 and the socket 2.

[0044] In addition, a VR device provided in this embodiment of the present invention includes the above-mentioned wire harness connection device.

[0045] The above-described 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, and should all be included within the protection scope of this utility model.
