Abstract
Description
A vehicle-mounted network switch Technical Field
[0001] This utility model relates to the field of network switch technology, specifically a vehicle-mounted network switch. Background Technology
[0002] The vehicle network switch is a core component in the vehicle electronic system that enables data communication between in-vehicle devices. It is mainly used to address the communication efficiency and data exchange needs brought about by the surge in the number of in-vehicle electronic devices.
[0003] In-vehicle network switches are typically installed below the center console of a car, close to core electronic devices. However, in-vehicle network switches have defects during vehicle operation: 1. In the vibration environment of long-term vehicle operation, vibration causes fatigue fracture of the plastic locking clips of the RJ45 connector (common in inferior or aged components), meaning the axial locking force of the RJ45 connector is insufficient, causing the connector to partially slip out of the Ethernet interface or even completely detach, resulting in intermittent signal or network connection interruption; 2. Due to vibration, the wiring harness swings, and the vibration is transmitted to the tail of the RJ45 connector, pulling on it. Over time, this can easily lead to fatigue fracture at the connection point (crimp point) between the wire core and the RJ45 connector terminal, resulting in the breakage of one or more wire cores and the failure of the corresponding pin signals. Therefore, the above problems urgently need to be solved. Summary of the Invention
[0004] (a) Technical problems to be solved

An L-shaped positioning block is fixedly mounted on the top of the switch body, with one end of the L-shaped positioning block located in front of the Ethernet ports. A vertically arranged rubber pad is fixedly connected to the side of the L-shaped positioning block near the Ethernet ports.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Please refer to Figures 1 and 2. This utility model provides a technical solution: a vehicle-mounted network switch, including a switch body 1 and a plurality of Ethernet interfaces 101 opened on the front side wall of the switch body 1. An L-shaped positioning block 2 can be fixedly installed on the top of the switch body 1. One end of the L-shaped positioning block 2 is located in front of the Ethernet interface 101. A vertically arranged rubber pad 4 is fixedly connected to the side of the L-shaped positioning block 2 near the Ethernet interface 101. An opening 201 is opened at the end of the L-shaped positioning block 2. The L-shaped positioning block 2 is also provided with an elastic clamping component 5, and the position of the elastic clamping component 5 corresponds to the opening 201.
[0023] Insert the crystal head 8 at one end of the wire harness 7 that connects to other electronic devices into the Ethernet interface 101. This application provides an L-shaped positioning block 2 on the top of the switch body 1, so that the end of the L-shaped positioning block 2 abuts against the crystal head 8 inserted into the Ethernet interface 101, thereby ensuring that the crystal head 8 can be stably located inside the Ethernet interface 101, preventing it from falling off, ensuring the stability of the transmitted signal, and the rubber pad 4 directly contacts the crystal head 8, reducing wear and having the purpose of buffering and shock absorption.
[0024] By setting the elastic clamping component 5, the wire harness 7 can be clamped and fixed, preventing the wire harness 7 from being transmitted to the tail of the crystal head 8 due to vibration, and minimizing the pulling of the wire harness 7 on the tail of the crystal head 8.
[0025] Referring to Figures 3 and 4, the elastic clamping assembly 5 includes two brackets 53 fixed to the end of the L-shaped positioning block 2. A rotating shaft 55 is rotatably inserted between the inner walls of the brackets 53. A connecting rod 52 is fixedly connected to the rotating shaft 55. A clamping block 51 is fixedly connected to the other end of the connecting rod 52. The inner side of the clamping block 51 has silicone rubber. A torsion spring 54 is fixedly connected between the inner wall of the brackets 53 and the connecting rod 52.
[0026] The wire harness 7 is clamped between two clamping blocks 51. Under the torque of the torsion spring 54, the two clamping blocks 51 can firmly and stably clamp and fix the wire harness 7. When the car vibrates, the vibration of the wire harness 7 is prevented from being transmitted to the tail of the crystal head 8. The vibration stops after being transmitted to the clamping block 51, thus minimizing the pulling of the wire harness 7 on the tail of the crystal head 8. The silicone rubber inside the clamping block 51 wraps the wire harness 7, transferring the vibration to the silicone rubber, which serves to buffer and reduce shock, thereby improving the durability between the wire harness 7 and the crystal head 8.
[0027] Referring to Figure 3, the clamping block 51 has an overall arc-shaped structure.
[0028] The clamping block 51 has an overall arc-shaped structure that matches the structure of the wire harness 7. The radius of curvature of the arc-shaped structure is precisely matched with the outer diameter of the wire harness 7, forming a surface contact fixation. This fully clamps and fixes the wire harness 7, preventing it from slipping out during the fixing process. Furthermore, the silicone rubber on the inner side of the clamping block 51 usually has the function of compensating for clamping gaps.
[0029] Referring to Figures 1 and 3, the L-shaped positioning block 2 has a through hole 202 on its top, and a bolt 3 is movably inserted into the through hole 202. The top of the switch body 1 has multiple screw holes 102. When the L-shaped positioning block 2 is fixedly installed on the top of the switch body 1, the threaded end of the bolt 3 is threaded into the screw hole 102.
[0030] Each L-shaped positioning block 2 has two through holes 202, corresponding to two screw holes 102. By locking with bolts 3, the L-shaped positioning block 2 can be stably fixed on the switch body 1.
[0031] Referring to Figure 2, positioning strips 6 are fixedly connected to both sides of the switch body 1, and positioning holes 601 are provided on the positioning strips 6.
[0032] In order to fix the switch body 1 as a whole inside the car, fasteners are installed inside the positioning hole 601 and connected to the preset connection hole inside the car to achieve the purpose of fixing the switch body 1. This fixing method is the prior art and will not be described in detail. In addition, the switch body 1 improved in this application is a common mainstream model in the prior art, such as DAP vehicle switch and UGREEN network switch. Those skilled in the art can independently learn about it and it has technical inspiration for other corresponding mainstream models.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
