Description

Technical Field

[0001] This utility model relates to the field of connector structure, and in particular to an automotive Ethernet connector with high anti-interference performance. Background Technology

[0002] With the rapid development of the automotive industry, the communication demands of vehicles are gradually increasing. Traditional automotive electronic communication buses, such as the CAN bus, can no longer meet the growing data transmission requirements. Firstly, traditional Ethernet connectors often lack effective shielding designs, making them susceptible to electromagnetic interference from components such as the engine, motor, and high-voltage wiring harness in the complex automotive electromagnetic environment. This can lead to data transmission errors, signal attenuation, or even communication interruptions, severely impacting the normal operation of the vehicle's electronic systems. Secondly, vehicles face various harsh environments during operation, such as rain, mud, and dust. Over time, moisture and impurities can easily penetrate the connector, causing poor contact, corrosion, or short circuits, thus affecting communication quality. Furthermore, the strong vibrations and impacts generated during vehicle operation place extremely high demands on the stability and reliability of connectors. The inadequacies of traditional connectors in their shock-resistant design make them prone to loosening, wear, or breakage during long-term use, leading to communication failures.

Detailed Implementation

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] This embodiment provides an automotive Ethernet connector with high anti-interference performance, as shown in the attached diagram. Figure 1-3 The device includes an outer shell 1, terminals 2, an insulating core 3, a first shielding shell 4, a second shielding shell 5, and an end cap 6. Terminals 2 are located inside the insulating core 3. The first shielding shell 4 covers the outside of the insulating core 3. The second shielding shell 5 accommodates the wire body 7. An internal mounting cavity 11 extends through the outer shell 1. The first shielding shell 4 and the second shielding shell 5 are located within the mounting cavity 11. The front end of the second shielding shell 5 extends into the end of the first shielding shell 4. The end cap 6 of the outer shell 1 has an end cap 6, with an opening in the middle. The device has a wire hole 61 through which the wire can pass. A positioning spring 51 is provided between the end cap 6 and the second shielding shell 5. A first positioning spring 41 and a second positioning spring 42 are provided on the outer side of the first shielding shell 4. The first positioning spring 41 and the second positioning spring 42 extend outward in opposite directions. A first positioning boss 111 and a second positioning boss 112 are provided on the inner side of the mounting cavity 11. The first positioning spring 41 and the second positioning spring 42 abut against the first positioning boss 111 and the second positioning boss 112, respectively.

[0020] By setting an insulating core 3 on the outside of terminal 2 and covering the outside of the first shielding shell 4 and the second shielding shell 5 with the insulating core 3, the shielding structure formed by the first shielding shell 4 and the second shielding shell 5 can effectively resist electromagnetic interference from other components, reduce the risk of data transmission errors, signal attenuation and communication interruption, and improve the anti-interference performance of the connector. The first shielding shell 4 is axially fixed to the outer shell 1 by the abutment of the first positioning spring 41 and the second positioning spring 42 against the first positioning boss 111 and the second positioning boss 112 in the mounting cavity 11. At the same time, the positioning spring 51 set between the end cover 6 and the second shielding shell 5 realizes the axial positioning of the second shielding shell 5. Thus, it can effectively resist the strong vibration and impact generated during the operation of the car, reduce the risk of connector loosening, wear or breakage, and improve the stability and reliability of the connector.

[0021] Preferably, it also includes a first sealing ring 91, which is embedded inside the mounting cavity 11. By providing the first sealing ring 91 inside the mounting cavity 11, it achieves a sealing effect between the connector and the corresponding interface, preventing moisture, dust, or other impurities from entering the connector through the gap between the connector and the corresponding interface, thereby avoiding problems such as poor contact, corrosion, or short circuits, and improving the connector's anti-interference performance. In addition, the first seal also plays a certain role in buffering vibration and impact, improving the stability of the connector.

[0022] Furthermore, a first annular groove 113 is provided on the inner side of the mounting cavity 11. The horizontal position of the first annular groove 113 is located between the front end of the outer shell 1 and the front end of the first shielding shell 4. The first sealing ring 91 is placed in the first annular groove 113.

[0023] By providing a first annular groove 113, the first sealing ring 91 is positioned to ensure that the inner side of the first sealing ring 91 fits against the outer side of the corresponding interface, thus guaranteeing a sealing effect. By horizontally positioning the first annular groove 113 between the front end of the outer shell 1 and the front end of the first shielding shell 4, moisture, dust, or other impurities are prevented from entering the terminal 2 through the gap between the connector and the corresponding interface.

[0024] Preferably, one end of the end cap 6 is provided with a sealing plug 62, which extends into the outer shell 1, and the outer side of the sealing plug 62 fits against the inner side of the mounting cavity 11.

[0025] By setting a sealing plug 62 at the end of the end cap 6, and the sealing plug 62 extending into the housing 1, moisture, dust or other impurities are prevented from entering the connector through the gap between the end cap 6 and the housing 1, thereby improving the connector's waterproof and anti-interference performance and avoiding problems such as poor contact, corrosion or short circuit.

[0026] Preferably, it also includes a TPA component 8, with a lower opening 12 at the bottom of the housing 1 and fastening portions 81 on both sides of the housing 1. The TPA component 8 is detachably connected to the housing 1 by cooperating with the fastening portions 81 and covers the lower opening 12 of the housing 1.

[0027] By opening a lower opening 12 at the bottom of the housing 1, the TPA component 8 can extend into the housing 1 through the lower opening 12 and contact the first shielding shell 4 and the second shielding shell 5, ensuring the correct position of the terminal 2 in the connector, so as to prevent the terminal 2 from loosening or falling off during insertion or use.

[0028] Furthermore, it also includes a second sealing ring 92, and a second annular groove 121 is provided on the inner side of the lower opening 12. The second sealing ring 92 is placed in the second annular groove 121, and the inner side of the second sealing ring 92 is in contact with the TPA component 8.

[0029] By providing a second sealing ring 92 between the TPA component 8 and the lower opening 12 at the bottom of the housing 1, moisture, dust or other impurities are further prevented from entering the connector through the gap between the TPA component 8 and the housing 1, thereby improving the connector's waterproof and anti-interference performance and avoiding problems such as poor contact, corrosion or short circuit.

[0030] Preferably, positioning blocks 31 are provided on both sides of the insulating core 3, and a limiting groove 52 is provided at the front end of the second shielding shell 5, the limiting groove 52 matching the positioning blocks 31. By providing positioning blocks 31 on both sides of the insulating core 3 and providing a limiting groove 52 at the front end of the second shielding shell 5 that matches the positioning blocks 31, the axial and circumferential positioning of the insulating core 3 is achieved, avoiding loosening between the insulating core 3 and the second shielding shell 5 during long-term use.
