Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and particularly relates to a vehicle-mounted Ethernet connector. Background Art

[0002] With the increasing popularity of automobiles, the use of emerging technologies such as high-definition entertainment and vehicle networking in vehicles, and the emergence of vehicle-mounted Ethernet buses, vehicle-mounted Ethernet connectors have been widely promoted. During the SMT reflow soldering process of Ethernet connectors, board-end connectors are usually fixed to the circuit board grounding loop by means of shielding case soldering. In order to meet the shielding attenuation requirements of Open alliance TC9, most of the shielding cases of Ethernet board-end connectors are made by die-casting zinc alloy in one piece, and the shielding GND soldering surface uses SMT and positioning post soldering methods. In the traditional design of Ethernet connectors, the positioning posts of the shielding case are connected to the Sand-off soldering surface of the shielding case, and the solder is likely to accumulate inward along the metal surface of the shielding soldering surface of the connector. This may not only cause insufficient solder in the welding holes of the positioning posts, but also may lead to interference with normal signal transmission due to insufficient grounding, reducing the shielding performance and reliability of the connector. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a vehicle-mounted Ethernet connector, which can effectively avoid insufficient soldering amount in the positioning post holes of the shielding case, make the grounding of the positioning posts be fully welded and connected, improve the reliability of the connector, and enhance the electrical performance of the connector, so as to solve the deficiencies of the prior art.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A vehicle-mounted Ethernet connector has multiple signal transmission channels, including: a plastic shell, a shielding shell, signal terminals, and an insulating medium. The signal terminals are fixed in the insulating medium, the insulating medium is sleeved inside the shielding shell, and the plastic shell is sleeved outside the shielding shell; the signal terminals are installed on the welding area of the printed circuit board as signal welding feet, and the shielding shell installed on the welding area of the printed circuit board includes positioning posts and a welding step surface protruding from the bottom surface of the shielding shell. The positioning posts and the welding step surface are arranged at intervals in a segmented manner and surround the signal welding feet to form a complete signal transmission channel.

[0006] Furthermore, it also includes a lock. Lock holes communicating with each other are respectively arranged on the plastic shell and the shielding shell, and the lock is inserted into the lock holes to fix the plastic shell and the shielding shell together.

[0007] Further, the positioning posts and soldering step surfaces arranged around each signal transmission channel are connected in series to form a grounding ring with an elliptical trajectory.

[0008] Further, every two of the positioning posts and the soldering step surfaces are arranged at intervals with mutual dislocation.

[0009] Further, there are four positioning posts and four soldering step surfaces.

[0010] Further, the length of the soldering step surface on the long side of the elliptical trajectory is greater than the length of the soldering step surface on the short side of the elliptical trajectory.

[0011] In the present utility model, the soldering step surface of the shielding housing and the positioning posts are arranged separately from each other, and all are separated in the middle, so that the solder between the soldering step surface and the positioning posts will not accumulate with each other, ensuring that a complete grounding ring is provided around each signal transmission channel, thereby effectively ensuring the performance and reliability of the Ethernet connector.

[0017] By providing an in-vehicle Ethernet connector in an embodiment of the present application, the technical problem in the prior art that during the soldering process, the welding holes of the positioning posts of the shielding shell gather towards the inside of the shielding shell welding surface, affecting the reliability and electrical performance of the Ethernet connector is solved.

[0018] The technical solution in the embodiment of the present application to solve the above technical problem has the following general idea:

[0019] By designing a vehicle-mounted Ethernet connector, the welding step surface of the shielding shell and the positioning posts are arranged separately from each other, with all the spaces in between separated, so that the solder between the welding step surface and the positioning posts will not accumulate on each other, ensuring that a complete grounding ring is provided around each signal transmission channel, thereby effectively guaranteeing the good performance and reliability of the Ethernet connector.

[0020] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0021] As Figures 1 to 3 shown, it is an embodiment of the present application:

[0022] A vehicle-mounted Ethernet connector 1 has six signal transmission channels, including: a plastic shell 20, a shielding shell 30, signal terminals 40, and an insulating medium 50. The signal terminals 40 are fixed to the insulating medium 50, the insulating medium 50 is sleeved inside the shielding shell 30, and the plastic shell 20 is sleeved outside the shielding shell 30. The signal terminals 40 are installed in the welding area of the printed circuit board as signal welding pins 401. The shielding shell 30 is installed in the welding area of the printed circuit board and includes positioning posts 301 and a welding step surface 302 protruding from the bottom surface of the shielding shell. The positioning posts 301 and the welding step surface 302 are arranged at intervals in a segmented manner and surround the signal welding pins 401 to form a complete signal transmission channel.

[0023] Specifically in combination with Figure 1 shown, it further includes a lock 60. The plastic shell 20 and the shielding shell 30 are respectively provided with communicating lock holes 70, and the lock 60 is inserted into the lock holes 70 to fix the plastic shell 20 and the shielding shell 30 together.

[0024] Specifically in combination with Figure 2As shown, the positioning posts 301 and welding step surfaces 302 arranged around each signal transmission channel are connected in series to form a grounding ring with an elliptical trajectory. Every two of the positioning posts 301 and the welding step surfaces 302 are arranged at intervals and offset from each other. During the soldering process, the SMT and positioning post welding methods are adopted. The solder in the area of the positioning posts 301 of the shielding housing 30 will not gather along the welding step surface 302 into the connector, so that the solder between the positioning posts 301 and the welding step surfaces 302 will not affect each other, effectively ensuring the good reliability of the Ethernet connector and enhancing the electrical performance of the Ethernet connector.

[0025] Specifically combined with Figure 3 As shown, in this embodiment, one of the signal transmission channels is selected for illustration. There are four positioning posts 301, which are distributed outside the signal welding pins 401. There are four welding step surfaces 302, and the length of the welding step surface 302 on the long side of the elliptical trajectory is greater than the length of the welding step surface on the short side of the elliptical trajectory. The four welding step surfaces 302 are also distributed outside the signal welding pins 401, forming a grounding ring with an elliptical trajectory with the positioning posts 301. The four positioning posts 301 and the four welding step surfaces 302 are all separated in the middle, so that the solder between the welding step surfaces 302 and the positioning posts 301 will not accumulate on each other, ensuring that a complete grounding ring is provided around each signal transmission channel, thereby effectively ensuring the performance and reliability of the Ethernet connector.

[0026] In summary, for a vehicle-mounted Ethernet connector provided by the present utility model, the welding step surface of the shielding housing and the positioning posts are arranged to be disconnected from each other and all separated in the middle, so that the solder between the welding step surface and the positioning posts will not gather on each other, thereby protecting the internal components from damage, ensuring that a complete grounding ring is provided around each signal transmission channel, and further effectively ensuring the good performance and reliability of the Ethernet connector.

[0027] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0028] The above-described embodiments only express the implementation manners of the present utility model, and the description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model should be subject to the appended claims.
