This is also placing increasing demands on the structural design, exterior design, and materials used for these connectors.

[0003] The prior art CN115207663A discloses a coaxial connector and an outer conductor. The coaxial connector includes an outer conductor, an insulator and an inner conductor coaxially sleeved together, with the mating end of the outer conductor as the front end.

[0005] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0009] A second contact portion is formed on the elastic arm, and a second contact point is provided on the second contact portion.

[0010] Furthermore, the first contact portion and the second contact portion are both protrusions formed by punching or bending.

[0011] Furthermore, the first contact point is the highest point of the first contact portion, and the second contact point is the highest point of the second contact portion; the first contact point and the second contact point are used to form an electrical connection between the outer conductor structure and the engaged corresponding connector.

[0014] Furthermore, one end of the elastic arm away from the outer conductor substrate is set as an end portion, and the outer wall of the connecting ring is higher than the outer wall of the end portion.

[0015] Furthermore, the number of the connecting arms is 4.

[0016] Furthermore, the connecting ring is a closed ring.

[0017] Furthermore, the outer conductor structure is obtained by stamping.

[0018] Furthermore, the cross-sectional profile of the outer conductor substrate is a waist-shaped hole structure.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] (1) The outer conductor structure of the present invention is plugged into the corresponding connector through the first contact portion and the second contact portion. The first contact point on the first contact portion and the second contact point on the second contact portion are in contact with the corresponding connector, so that the outer conductor structure and the corresponding connector are electrically connected, and the outer conductor structure and the corresponding connector form a point-to-surface connection relationship, which reduces the contact area during plugging and unplugging, and reduces the plugging and unplugging force between the outer conductor structure and the corresponding connector while ensuring improved reliability.

[0025] The technical solution of the present invention will be clearly described below in conjunction with the accompanying drawings. Obviously, the embodiments described are not all embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It should be noted that the directions or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", and "horizontal" are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0026] like Figure 1 As shown, the utility model provides an outer conductor structure for in-vehicle Ethernet, comprising an outer conductor substrate 1, an outer conductor support 2 and a plurality of elastic arms 3; the cross-sectional profile of the outer conductor substrate 1 is set to a waist-shaped hole structure, one end of the outer conductor substrate 1 is integrally connected to the outer conductor support 2, the outer conductor support 2 comprises a plurality of connecting arms 21 and a connecting ring 23, a plurality of connecting arms 21 are integrally connected to the connecting ring 23, each connecting arm 21 is arranged along the axial direction of the outer conductor support 2, and the plurality of connecting arms 21 are arranged at intervals along the circumference of the connecting ring 23. Preferably, four connecting arms 21 are provided, and the end of the connecting arm 21 away from the connecting ring 23 is integrally connected to the outer conductor substrate 1, that is, the connecting arm 21 is integrally connected between the outer conductor substrate 1 and the connecting ring 23; an accommodating space is provided between two adjacent connecting arms 21, and at least one elastic arm 3 is provided in each accommodating space, the elastic arm 3 is arranged along the axial direction of the outer conductor support 2, one end of the elastic arm 3 is integrally connected to the outer conductor substrate 1, and the other end of the elastic arm 3 is spaced apart from the connecting ring 23.

[0027] The connecting ring 23 is a closed ring, which can improve the stability and reliability of the outer conductor support 2 .

[0028] The connecting arm 21 is provided with a first contact portion 22, which is arranged away from the outer conductor substrate 1. The first contact portion 22 is a protrusion formed by punching or bending. A first contact point 24 is provided on the first contact portion 22. The first contact point 24 is the highest point of the first contact portion 22, that is, the point on the first contact portion 22 that is farthest vertically from the axis of the outer conductor bracket 2. The first contact point 24 is used to form an electrical connection between the outer conductor structure of the utility model and the corresponding engaged connector.

[0029] A second contact portion 31 is provided on the elastic arm 3, and the second contact portion 31 is arranged away from the outer conductor substrate 1. The second contact portion 31 is a protrusion formed by punching or bending. A second contact point 33 is provided on the second contact portion 31. The second contact point 33 is the highest point of the second contact portion 31, that is, the point on the second contact portion 31 that is farthest vertically from the axis of the outer conductor bracket 2. The second contact point 33 is used to form an electrical connection between the outer conductor structure of the present invention and the corresponding engaged connector.

[0030] Providing a first contact point 24 on the connecting arm 21 and a second contact point 33 on the elastic arm 3 can reduce the plugging and unplugging force. In the absence of the first contact point 24 and the second contact point 33, the first contact portion 22 on the connecting arm 21 and the second contact portion 31 on the elastic arm 3 are engaged with the corresponding connector, and the plugging and unplugging force during contact is relatively large. After providing the first contact point 24 and the second contact point 33, the line-surface contact is changed to point-surface release, which reduces the contact area during plugging and unplugging, reduces the plugging and unplugging force, and improves the reliability during contact.

[0031] The first contact points 24 and the second contact points 33 are arranged offset from each other in the axial direction of the outer conductor support 2, the first contact points 24 are arranged offset from each other in the axial direction of the outer conductor support 2, and the second contact points 23 are also arranged offset from each other in the axial direction of the outer conductor support 2. The offset arrangement can reduce the maximum insertion and extraction force when the outer conductor structure of the present invention is inserted into the corresponding connector.

[0032] like Figure 2 As shown, the end of the elastic arm 3 away from the outer conductor substrate 1 is set as the end 32. There is a certain distance between the end 32 and the connecting ring 23. The outer wall of the connecting ring 23 is higher than the outer wall of the end 32, that is, the vertical distance from the outer wall of the end 32 to the axis of the outer conductor support 2 is smaller than the vertical distance from the outer wall of the connecting ring 23 to the axis of the outer conductor support 2, which is used to protect the elastic arm 3 from mechanical forces.

[0033] The outer conductor structure provided by the utility model is obtained by stamping.

[0034] The working principle of an outer conductor structure for in-vehicle Ethernet provided by the present invention is as follows: the outer conductor structure of the present invention is inserted into the interior of a corresponding connector, the connecting arm 21 is arranged in the form of a simply supported beam in the outer conductor structure, and the outer conductor structure is plugged into the corresponding connector through the first contact portion 22 and the second contact portion 31. The first contact point 24 on the first contact portion 22 and the second contact point 33 on the second contact portion 31 are in contact with the corresponding connector, so that the outer conductor structure and the corresponding connector form an electrical connection, and the outer conductor structure and the corresponding connector form a point-to-surface connection relationship, which reduces the contact area during plugging and unplugging, and reduces the plugging and unplugging force between the outer conductor structure and the corresponding connector while ensuring improved reliability.

[0035] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Simple modifications or equivalent replacements of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
