One end of the short terminal assembly 50 enters the receiving cavity 102 through the first notch 103 and is inserted into the upper and lower rows of plug-in posts 101 respectively. The other end extends out of the receiving cavity 102. Both the long terminal assembly 40 and the short terminal assembly 50 include a center terminal 501 and an insulator 502 disposed outside a portion of the center terminal 501. The insulator 502 has at least one second rib 503 protruding from the end that mates with the plug-in post 101. The long terminal assembly 40 and the short terminal assembly 50 achieve initial installation and positioning by hard interference between the second rib 503 and the inner wall of the plug-in post 101. The bottom of the main body 110 has a third notch 108 communicating with the receiving cavity 102. The end of the center terminal 301 protrudes from the third notch 108 and is disposed outside the outer conductor 10. For details, please refer to Figure 2 , Figure 7 and Figure 8The end of the center terminal 301 is used for soldering to the printed circuit board. The accommodating cavity 102 is also provided with a first fixing seat 20 and a second fixing seat 60 made of metal material. The first fixing seat 20 is disposed between the other end of the long terminal assembly 40 and the short terminal assembly 50. The second fixing seat 60 is inserted into the accommodating cavity 102 and is located on the opposite side of the long terminal assembly 40 relative to the first fixing seat 20.

[0043] In some embodiments, two long terminal assemblies 40 and two short terminal assemblies 50 are arranged side by side; at least one plug-in seat 104 is formed in the accommodating cavity 102 along the vertical direction to separate different short terminal assemblies 50 and different long terminal assemblies 40; the first fixing seat 20 includes a plug-in plate 201 that is plugged into the plug-in seat 104 and fixing parts 202 provided on both sides of the front end of the plug-in plate 201, the fixing parts 202 abutting against the rear end of at least two short terminal assemblies 50 after the plug-in plate 201 is inserted into the plug-in seat 104; the second fixing seat 60 is provided with a slot 601 that matches the shape of the plug-in seat 104, the second fixing seat 60 is inserted into the outside of the plug-in seat 104 and the plug-in plate 201 through the slot 601, and the front end of the second fixing seat 60 abuts against the rear end of at least two long terminal assemblies 40. Here, the top of the outer conductor 10 has a second notch 105 communicating with the receiving cavity 102. The second fixing seat 60 enters the receiving cavity through the second notch 105 and is then inserted to the outside of the plug-in seat 104 and the plug-in plate 201. The first fixing seat 20 and the second fixing seat 60 are inserted from different directions of the outer conductor 10 to fix at least two long terminal assemblies 40 and at least two short terminal assemblies 50 installed in the receiving cavity 102 of the outer conductor 10. At the same time, the first fixing seat 20 and the second fixing seat 60 interfere with each other through the plug-in seat 104 provided in the receiving cavity 102 to prevent them from coming out of the receiving cavity 102 of the outer conductor 10. Furthermore, the planes containing the first notch 103, the second notch 105, and the plug-in seat 104 can be arranged perpendicularly to each other, so that the insertion directions of the first fixing seat 20 and the second fixing seat 60 are perpendicular, which facilitates the installation of the first fixing seat 20 and the second fixing seat 60 and makes them have good structural stability after installation. Furthermore, the plug-in socket 104 and the first fixing seat 20 cooperate through the plug-in plate 201, and the second fixing seat 60 is inserted into the outside of the plug-in socket 104 and the plug-in plate 201 through the slot 601, thereby avoiding the formation of an air gap between the first fixing seat 20 and the outer conductor 10, which would interfere with the signal transmission of the long terminal assembly 40 and the short terminal assembly 50, thereby improving the product performance of the Ethernet board-end connector of the present invention.

[0044] In one implementation, such as Figure 6 and Figure 8As shown, both the long terminal assembly 40 and the short terminal assembly 50 include a horizontal section 401, a bent section 402, and a vertical section 403. The horizontal section 401 is partially inserted into the insertion post 101. The front end of the fixing part 202 has a first receiving groove 203 corresponding to the bent section 402 and the vertical section 403 of the short terminal assembly 50. The front end of the second fixing seat 60 has a second receiving groove 602 corresponding to the bent section 402 and the vertical section 403 of the long terminal assembly 40. Both the first receiving groove 203 and the second receiving groove 602 are arc-shaped grooves. These arc-shaped grooves correspond to the long terminal assembly 40 / short terminal assembly 50. The shapes of the bent section 402 and the vertical section 403 correspond to each other, and after the first fixing seat 20 and the second fixing seat 60 are installed, they fit against the rear end of the bent section 402 and the vertical section 403 of the long terminal assembly 40 / short terminal assembly 50. The first fixing seat 20 and the second fixing seat 60 fix at least two long terminal assemblies 40 and at least two short terminal assemblies 50 installed in the receiving cavity 102 of the outer conductor 10 through the first receiving groove 203 and the second receiving groove 602, so as to prevent at least two long terminal assemblies 40 and at least two short terminal assemblies 50 from retracting when the mating connector is installed, causing a short circuit.

[0045] Furthermore, such as Figure 6 and Figure 8 As shown, the rear end of the fixing part 202 is provided with a third receiving groove 204 corresponding to the vertical section 403 of the long terminal assembly 40. The third receiving groove 204 and the second receiving groove 602 together form a long terminal chamber 70 for holding the long terminal assembly 40. The interior of the outer conductor 10 is formed with a fourth receiving groove 106 corresponding to the vertical section 403 of the short terminal assembly 50. The first receiving groove 203 and the fourth receiving groove 106 together form a short terminal chamber 80 for holding the short terminal assembly 50. After the first fixing seat 20 and the second fixing seat 60 are installed, at least two long terminal assemblies 40 and at least two short terminal assemblies 50 are clamped in the corresponding long terminal chamber 70 and short terminal chamber 80. On the one hand, it can achieve good fixation of at least two long terminal assemblies 40 and at least two short terminal assemblies 50. On the other hand, the first fixing seat 20 and the second fixing seat 60 are both made of metal material, which, when combined with the outer conductor 10, can ensure stable signal transmission of the long terminal assembly and the short terminal assembly.

[0046] In one implementation, such as Figure 1 , Figure 3 and Figure 4As shown, the connector 104 includes a first connector track 1041 and a second connector track 1042 disposed opposite to each other. The two sidewalls of the connector plate 201 in the insertion direction are formed with connector portions 2011 that mate with the first connector track 1041 and the second connector track 1042. The front ends of the first connector track 1041 and the second connector track 1042 are connected by a baffle 1043. After the connector plate 201 is inserted into the first connector track 1041 and the second connector track 1042 through the connector portions 2011, it abuts against the baffle 1043. The baffle 1043, the connector plate 201, the first connector track 1041, and the second connector track 1042 together separate different short terminal assemblies 50 and different long terminal assemblies 40. For details, please refer to [link to relevant documentation]. Figure 5 This effectively shields and isolates different terminal components, preventing mutual interference between them during signal transmission, thereby improving the performance of the Ethernet board connector of this invention.

[0047] Furthermore, such as Figure 4 As shown, a first overlapping plate 2012 is formed on the plug plate 201. The rear ends of the first plug track 1041 and the second plug track 1042 are provided with recessed areas 1044 that match the shape of the first overlapping plate 2012. After the plug plate 201 is inserted into the first plug track 1041 and the second plug track 1042 through the plug part 2011, the first overlapping plate 2012 of the plug plate 201 is embedded in the recessed area 1044. The first overlapping plate 2012 facilitates the insertion of the plug plate 201 and the removal of the plug plate 201 from the first plug track 1041 and the second plug track 1042. To further prevent the formation of an air gap between the first fixing seat 20 and the outer conductor 10, which would interfere with the signal transmission of the long terminal assembly 40 and the short terminal assembly 50, an embedding groove (not shown in the figure) can be provided on the baffle 1043. After the plug plate 201 is inserted into the first plug rail 1041 and the second plug rail 1042 through the plug part 2011, the front end of the plug plate 201 is embedded in the embedding groove.

[0048] In one implementation, such as Figure 1 As shown, a second lap plate 603 is formed on the top of the second fixing seat 60, and a tiered structure 107 for embedding the second lap plate 603 is provided circumferentially along the edge of the second notch 105. After the outer conductor 10 is inserted into the second fixing seat 60, the second lap plate 603 is embedded in the tiered structure 107 formed on the second notch 105, thereby preventing the formation of an air gap between the second fixing seat 60 and the outer conductor 10, which would interfere with the signal transmission of the long terminal assembly 40 and the short terminal assembly 50, and further improving the product performance of the Ethernet board-end connector of the present invention.

[0049] Furthermore, such as Figure 1As shown, at least one first rib 604 is provided on the outer wall of the second fixing seat 60. The first rib 604 is specifically arranged along the direction in which the second fixing seat 60 is inserted into the outer conductor 10. After the second fixing seat 60 is inserted into the outer conductor 10, the first rib 604 interferes with the inner wall of the accommodating cavity 102, thereby further preventing the second fixing seat 60 from exiting the outer conductor 10.
