Description

Technical Field

[0001] This utility model relates to the technical field of connectors, specifically to an outer conductor structure for an automotive Ethernet connector. Background Technology

[0002] With the advancement of intelligent technologies in the automotive industry, there is a greater demand for high-speed and stable networks in areas such as autonomous driving, artificial intelligence, audio-visual entertainment, and LiDAR. Since in-vehicle network systems face harsh environmental conditions, especially vibrations during driving, and network stability has a significant impact on safe driving systems (particularly intelligent driving), the stability and reliability of Ethernet are paramount.

[0003] In the prior art, the outer conductor structure of automotive Ethernet connectors is usually used to achieve electromagnetic shielding and mechanical connection functions, but it has the following problems and shortcomings: In the automotive environment, the vibration and impact generated during vehicle operation place high demands on the stability of the connector. After the traditional outer conductor structure is inserted into the opposing component, it is prone to unstable contact due to shaking because it does not have enough limiting and support structure, which affects the long-term reliability of the connector. Summary of the Invention

[0004] The purpose of this utility model is to provide an outer conductor structure for an in-vehicle Ethernet connector to overcome the above-mentioned defects in the prior art.

[0005] An outer conductor structure for an automotive Ethernet connector includes an outer conductor base. The front end region of the outer conductor base is provided with a plurality of connecting arms. The front end of each connecting arm is provided with an outer conductor ring. A cavity space is provided between adjacent connecting arms. Each cavity space is provided with a first contact lug. Side spaces are provided on two connecting arms located on both sides of the outer conductor base. Each side space is provided with a second contact lug. A contact protrusion is provided in the middle of the outer conductor base.

[0006] Preferably, all connecting arms extend to the front end and bend inward to form a closed outer conductor loop.

[0007] Preferably, the outer conductor substrate has a thrust boss at its tail end.

[0008] Preferably, the thrust boss has an overall arc-shaped structure, but the side facing the outer conductor ring is a vertical plane.

[0009] Preferably, the size of the side space is smaller than the size of the cavity space.

[0010] Preferably, the first contact lug and the second contact lug have the same shape, but the size of the first contact lug is larger than the size of the second contact lug.

[0011] Preferably, the contact bumps are provided in two symmetrical locations on the upper and lower sides of the outer conductor substrate.

[0012] The beneficial effects achieved by this utility model are as follows:

[0013] This application achieves good contact and ensures shielding performance by interfering with the interface cavity sidewall of the outer conductor during implantation through contact lug 1 and contact lug 2, generating a positive force and elastic deformation. Simultaneously, contact lug 1 and contact lug 2 are protected by the surrounding structure, thus avoiding functional loss due to plastic deformation. After reaching the optimal position, the contact protrusions in the middle end region of the outer conductor substrate fill the gap between the outer conductor substrate and the outer conductor, reducing wobble and improving the product's assemblability and stability (Z-axis and Y-axis) without increasing implantation force.

[0020] The term "embodiment" as used herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of the phrase "embodiment" in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments.

[0021] like Figure 1-3 As shown, this utility model provides an outer conductor structure for an in-vehicle Ethernet connector, including an outer conductor base 1. The front end region of the outer conductor base 1 is provided with a plurality of connecting arms 2. All connecting arms 2 extend to the front end and bend inward to form a closed outer conductor ring 3.

[0022] In addition, a cavity space 4 is provided between adjacent connecting arms 2, and each cavity space 4 is provided with a contact lug 5. The two connecting arms 2 located on both sides of the outer conductor base 1 are provided with side spaces 6, and each side space 6 is provided with a contact lug 7. The size of the side space 6 is smaller than the size of the cavity space 4. The contact lug 5 and the contact lug 7 have the same shape, but the size of the contact lug 5 is larger than the size of the contact lug 7. When the Ethernet connector is matched, the contact lug 5 and the contact lug 7 on the outer conductor base 1 are in the cavity space 4 and the side space 6 respectively. This allows the contact lug 5 and the contact lug 7 to be protected by the surrounding outer conductor ring 3, connecting arms 2 and outer conductor base 1 during the elastic deformation process under the action of mechanical force, thereby avoiding functional loss caused by plastic deformation. The contact lug 1 and the contact lug 2 are evenly arranged on the outer conductor base 1, so that the entire connector has a more uniform force distribution when mating.

[0023] In addition, the outer conductor base 1 is provided with contact bumps 8 in the middle. There are two contact bumps 8, which are symmetrically arranged on the upper and lower sides of the outer conductor base 1. After assembly, they are inserted into the mating interface cavity 91 of the outer conductor 9 along with the outer conductor base 1. The contact bumps 8 fill the gap between the two outer conductors, thereby reducing the amount of shaking and enhancing the stability of the connection.

[0024] It is worth noting that the outer conductor base 1 is provided with a thrust boss 11 at its tail end. The thrust boss 11 is an arc-shaped structure, but the side facing the outer conductor ring 3 is a vertical plane. When it reaches the outer conductor thrust surface, it forms a blocking limit through the thrust boss 11 on the outer conductor base 1 to reach the optimal stroke position.

[0025] The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
