[0024] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings: like Figure 1-6As shown, a snap-on type field self-termination Ethernet connector includes a base 1 for installing cables and an upper cover 2 for snapping on the base 1. The base 1 is provided with a cable rack 3 for connecting cables and installing the cables in the base 1. One end of the base 1 is provided with a plug connector 4 for plugging into an external socket. The other end of the base 1 is provided with a tail sleeve 5 for locking the base 1 and the upper cover 2. The plug connector 4 and the base 1 are integrally formed. The base 1, the plug connector 4 and the upper cover 2 are made of zinc alloy and have a nickel plating layer on the surface.

[0025] By setting the base 1 and the upper cover 2, when installing the cable, the cable is installed on the cable rack 3, and the cable rack 3 is installed into the base 1 after the upper cover 2 is buckled, and the electrical connection between the cable and the base 1 is completed. The base 1 and the upper cover 2 are locked by rotating the tail sleeve 5. No professional is required for on-site installation, and ordinary workers can directly assemble the connector manually without additional professional installation tools, saving the cost of installation. At the same time, the installation operation is simple and fast. And the base 1, the plug connector 4 and the upper cover 2 made of zinc alloy and provided with nickel plating on the surface effectively shield electromagnetic interference, reduce the interference of external signals on data transmission, and improve the clarity and stability of the signal. The base 1, the plug connector 4 and the upper cover 2 made of metal have extremely high mechanical strength and can withstand frequent plugging and unplugging and external impact without being easily damaged. It performs well in a humid or corrosive environment, effectively prolongs the service life, and has good thermal conductivity, which can effectively dissipate the heat generated during data transmission. Good heat dissipation capacity helps to maintain the stable operation of the equipment, especially under high load conditions, effectively reducing the working temperature of the connector.

[0026] The end of the upper cover 2 facing the plug connector 4 is rotatably arranged on the base 1 through a rotating seat 6, and the base 1 is provided with a locking spring 7 for clamping the upper cover 2. One end of the locking spring 7 is fixedly arranged on the upper end of the plug connector 4, and the other end of the locking spring 7 extends in the direction of the upper cover 2 and is located on the side of the upper cover 2 facing the locking spring 7, and the locking spring 7 is gradually inclined upward from the plug connector 4 to the upper cover 2. A mounting block 8 for mounting the locking spring 7 is fixedly arranged on the upper end of the plug connector 4, and a certain gap is left between the upper end surface of the mounting block 8 and the upper end surface of the plug connector 4. A pressing spring 9 is arranged on the upper end of the upper cover 2, and one end of the pressing spring 9 is fixedly arranged on the upper end of the upper cover 2 and the other end extends in the direction of the locking spring 7 and is clamped on the upper end of the locking spring 7, and the pressing spring 9 is in an inverted U shape. A section of the pressing spring piece 9 facing the locking spring piece 7 is provided with a slot 10 for locking onto the locking spring piece 7 , so as to ensure that the pressing spring piece 9 is always pressed against the locking spring piece 7 . When installing the cable, the upper cover 2 is rotated upward. During the rotation process, the pressing spring piece 9 drives the locking spring piece 7 to deform and bend downward toward one end of the upper cover 2 until the upper cover 2 is fully opened. At this time, one end of the pressing spring piece 9 drives the locking spring piece 7 to deform and bend downward toward one end of the upper cover 2, so that the locking spring piece 7 moves downward toward one end of the upper cover 2 and is located below the plane where the upper end of the mounting block 8 is located. After the bent pressing spring piece 9 is opened as the upper cover 2 is rotated, the direction of the force of the contact point between the pressing spring piece 9 and the locking spring piece 7 is toward the side away from the above-mentioned mounting block 8. The pressing spring piece 9 is dragged to move in this direction by the combined force direction of the contact point, so that the upper cover 2 is always kept in the open state, and the cable rack 3 inside the base 1 can be conveniently installed, and the upper cover 2 will not be accidentally buckled during the installation process due to the tilt of the base 1 or external wind.

[0027] The upper end of the cable rack 3 facing the tail sleeve 5 is provided with a first inclined surface 11 which is gradually inclined from top to bottom toward the tail sleeve 5. A guide frame 12 is fixedly provided in the upper cover 2 and is pressed against the end of the cable rack 3 facing the tail sleeve 5 so that the cable rack 3 is firmly installed in the base 1. The base 1 is provided with a direct connection terminal 22 which realizes the electrical connection between the cable and the plug connector 4 and pierces the cable skin during the installation of the cable rack 3. When the cable rack 3 is installed through the guide frame 12, the cable rack 3 is pressed into the direct connection terminal 22. The guide frame 12 on the upper cover 2 contacts the first inclined surface 11 on the wire rack 3 when the upper cover 2 is buckled. During the buckling process, the upper cover 2 drives the wire rack 3 to move away from the tail sleeve 5 and is completely installed in the base 1 through the guide frame 12 and the first inclined surface 11. During installation, the wire rack 3 can be easily installed in the base 1. At this time, the guide frame 12 is in a vertical state and parallel to the end face of the wire rack 3 facing the tail sleeve 5.

[0028] The upper cover 2 and the base 1 are respectively fixedly provided with connecting parts 13 that can be mutually buckled on the outer periphery of the cable at one end facing the tail sleeve 5. The tail sleeve 5 is sleeved on the outer periphery of the two connecting parts 13 through threaded connection to achieve locking between the upper cover 2 and the base 1. The upper cover 2 and the base 1 are respectively provided with a shielding connecting piece 14 extending toward the connecting part 13 and used to abut against the outer periphery of the cable. The shielding connecting piece 14 is arc-shaped and the opening direction faces the connecting part 13. The end of the tail sleeve 5 away from the base 1 is movably provided with a connecting seat 15 through a snap connection. The end of the connecting seat 15 away from the tail sleeve 5 is movably provided with a collar 16. The collar 16 is provided on the connecting seat 15 through a snap connection. The end of the connecting seat 15 facing the collar 16 is provided with a plurality of claws 17 for abutting against the cable. The end of the claw 17 away from the connecting seat 15 is provided with a second inclined surface 18 for clamping the cable. The collar 16 is made of rubber. Before installing the cable on the cable rack 3, the cable needs to be passed through the ring 16, the connecting seat 15 and the tail sleeve 5. After the installation is completed, the elastic shielding connecting piece 14 is pressed against the cable, which can adapt to cables within a larger diameter range, has strong versatility and saves costs.

[0029] A circuit board 19 is arranged in the base 1, and a bracket for protecting the circuit board 19 is arranged at the lower end of the plug connector 4. One end of the circuit board 19 is electrically connected to the above-mentioned direct connection terminal 22, and the other end of the circuit board 19 is provided with a plurality of first gold sheet terminals 20 and second gold sheet terminals 21 which are electrically connected to the external socket after being plugged in. The area of ​​the first gold sheet terminal 20 is 5.65mm², and the area of ​​the second gold sheet terminal 21 is 8.84mm². Pins PIN1-8 are arranged on the circuit board 19. The first gold sheet terminals 20 are arranged on PIN1, 2, 4, 5, 7, and 8 of the circuit board 19, respectively, and the second gold sheet terminals 21 are arranged on PIN3 and PIN6 of the circuit board 19. The parameters of the first gold sheet terminal 20, the second gold sheet terminal 21, and the pins PIN1-8 of the circuit board 19 are shown in the following table: The crosstalk and return loss test parameters are shown in the following table: By adjusting the line width of the pins PIN1-8 on the circuit board 19 and the distance between them, the near-end crosstalk is compensated and optimized to balance and suppress the crosstalk between the two pairs of signals, so that the amplitude and phase of the near-end crosstalk of the connector are better than the standard requirements. Whether the impedance is matched directly affects the performance of the return loss. The impedance is mainly affected by the electromagnetic field distribution around the trace, such as the width of the trace, the dielectric constant of the medium, the spacing between the differential lines, etc. Therefore, the circuit board 19 is used to transfer the cable and the connector plug, replacing the existing conventional cable and gold sheet direct connection method. The circuit board 19 with a dielectric constant of 4.2 FR4 is used as the transfer medium. The circuit board 19 routing design adopts 2 layers. One end of the circuit board 19 is connected to the direct connection terminal 22 by DIP pin welding. The other end of the circuit board 19 is connected by fisheye terminal DIP. By adjusting the width, height, thickness and area of ​​the first gold sheet terminal 20 and the second gold sheet terminal 21, the matching of the impedance of the entire loop is achieved, thereby improving the performance of the return loss.

[0030] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, the obvious changes or changes in the description derived therefrom are still within the scope of protection of the present invention.
