Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a fully shielded high-speed connector. Background Art

[0002] As military equipment performance continues to improve, the system's requirements for data transmission and processing capabilities are increasing. This places high demands on high-performance chips, low-loss transmission paths, and powerful software programs. Signal interconnection between different PCB boards and modules within the equipment is often achieved through connectors and cable assemblies. As a critical link in the transmission path, the performance of connectors and cable assemblies has become a major factor limiting overall system performance.

[0008] The wiring plug includes a head shell and a head signal unit. There are several head channel cavities on the head shell. The head signal unit is fixedly installed in the head channel cavity. The head signal unit includes a head base, a support plate, a pin, a shielding block, and a flat wire. One end of the pin is welded to the core wire of the flat wire. The support plates are arranged on both sides of the pin. The two support plates clamp the pin from both sides. The shielding block is sleeved on the surface of the flat wire. The support plate is arranged between the head base and the shielding block. One side of the head base is against one side of the support plate, and one side of the shielding block is against the other side of the support plate. The shielding block is electrically connected to the ground wire. A fixing plate is fixed to the fixed end of the seat shell. The fixing plate limits the fixed end of the seat signal unit in the seat channel cavity. Through holes are provided on the surface of the fixing plate, the same number as the seat channel cavities. A positioning boss is provided on the contact surface between the fixing plate and the seat shell. The positioning boss corresponds to the position of the through hole provided on the surface of the fixing plate.

[0009] A conductive rubber pad is provided between the plug-in socket and the wiring plug. When the head shell and the seat shell are plugged in and locked, the conductive rubber pad is in a compressed state, and the pin is inserted into the docking end of the plug rod; the positioning boss is pressed on the fixing bar, and the grounding pin, seat shell, conductive rubber pad, head shell, shielding block, and flat wire ground wire form a complete shielding channel on the data transmission path.

[0010] Furthermore, it also includes a seat locking accessory, which includes a nut and a screw. The nut is fixedly inserted into both sides of the seat shell, and the screw and the nut are screwed together through threads.

[0011] Furthermore, the grounding pin is shaped like an elliptical structure, and a grounding fisheye is provided on the end face of the grounding pin near the fixed end of the plug rod.

[0019] Beneficial effects of the present invention:

[0020] (1) In the fully shielded high-speed connector of the present invention, a conductive rubber pad is provided between the plug-in socket and the wiring plug. When the head shell and the seat shell are plugged in and locked, the conductive rubber pad is in a compressed state. The pin is inserted into the docking end of the plug rod. Due to its elastic properties, the contact surface of the seat shell and the contact surface of the head shell are fully in contact with the conductive rubber pad, ensuring good conductivity between the docking interface of the seat shell and the docking interface of the head shell. Inside the plug-in socket, the positioning boss of the fixing plate is pressed on the fixing bar of the ground pin. At this point, the ground pin, the seat shell, the conductive rubber pad, the head shell, the shielding block, and the ground wire of the flat wire form a connected, 360° fully shielded structure, a complete shielding channel on the data transmission path, achieving the effect of full-link shielding and avoiding signal interference between each channel.

[0021] (2) In the fully shielded high-speed connector of the present invention, the fixed end of the plug rod is connected to the PCB board by crimping the fisheye section, and the punched fisheye section and the four plug rods are welded together to form a component, thereby reducing the "short pile" effect in the signal transmission path and improving the high-speed transmission performance of the entire product.

[0022] (3) The fully shielded high-speed connector of the present invention has a plurality of spring sheets fixed to the butt end of the plug rod. The spring sheets are arranged in a ring along the butt end of the plug rod. The pin is inserted between the spring sheets and elastically contacts the spring sheets. The multiple elastic contact points are evenly distributed on the entire circumference, which greatly improves the vibration and impact resistance of the contact in all directions.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0034] Existing high-speed connectors have different types of contacts, such as pinhole and spring-type, to suit different application scenarios. Pinhole contacts often have multiple contact points distributed in a circumferential direction and have strong resistance to vibration and shock. They are often terminated to the printed circuit board by welding. Through-hole welding affects the high-speed performance of the product due to its "stub" effect. Surface-mount welding requires a large surface area and is not suitable for high-density, multi-pin products. Spring-type contacts are stamped parts and can be designed with a "fisheye" structure to be press-fitted into the PCB board. The cantilever beam structure in the contact area is difficult to withstand strong vibration and shock environments. Existing connectors also cannot fully shield the channels along the data transmission path, resulting in signal interference between each data transmission path channel, which restricts the overall performance of the system.

[0035] This embodiment proposes a fully shielded high-speed connector to solve the above-mentioned problem, which is described in detail in the following embodiments.

[0036] See also Figure 1 As shown, the fully shielded high-speed connector described in this embodiment includes a straight plug socket 1 and a wiring plug 2. The straight plug socket 1 is a fixed end and the wiring plug 2 is a free end. One side of the straight plug socket 1 is a fixed surface and the other side is a mating surface. The fixed surface of the straight plug socket 1 is connected and fixed to the PCB board, and the mating surface of the straight plug socket 1 is mated with the wiring plug 2. The connector also includes a seat locking accessory 15, which is used to fix the straight plug socket 1 to the surface of the PCB board.

[0037] The seat locking accessory 15 includes a nut 151 and a screw 152. The nut 151 is fixedly provided on both sides of the seat shell 11. The nut 151 is fixed to the seat shell 11 by a mortise and tenon method. Figure 1 and Figure 2As shown, the screw 152 is screwed together with the nut 151. When in use, the striking end of the screw 152 penetrates the PCB board and enters the nut 151. The screw 152 and the nut 151 are screwed together through threads. Tightening the screw 152 fixes the seat shell 11 and the PCB board. The reliable seat locking accessory 15 cooperates with the metal shell to avoid external force directly acting on the contact parts, which greatly improves the overall vibration and impact resistance of the connector.

[0038] The plug-in socket 1 includes a socket housing 11 and a socket signal unit 13. The socket housing 11 defines a plurality of socket passage cavities 111 arranged in an array. The socket signal unit 13 is fixedly disposed within the socket passage cavities 111. One end of the socket signal unit 13 is a docking end, located on the docking side of the plug-in socket 1. The other end of the socket signal unit 13 is a fixed end, located on the fixed side of the plug-in socket 1. The fixed end of the socket signal unit 13 is fixed to and electrically connected to the PCB. The docking end of the socket signal unit 13 is electrically connected to the head signal unit 22 installed in the wiring plug 2. The socket housing 11 is made of metal.

[0039] See also Figure 2 As shown, a fixing plate 12 is fixed to the fixed end of the seat shell 11, and the fixing plate 12 limits the fixed end of the seat signal unit 13 to the seat channel cavity 111. The surface of the fixing plate 12 is provided with through holes with the same number as the seat channel cavity 111, and the fixed end of the seat signal unit 13 passes through the through holes. Specifically, the fixing plate 12 is fixed to the seat shell 11 by a number of countersunk screws 16.

[0040] As shown in Figure 4 , the socket signal unit 13 comprises a socket base 131, a ground pin 132, a rod 133, and a fisheye section 134. An air cavity 1311 is defined on the surface of the socket base 131 to adjust the characteristic impedance and improve signal transmission performance. Rod 133 has a docking end at one end and a fixed end at the other. The docking end of rod 133 extends through ground pin 132 into the socket base 131, where it is secured to the socket base 131 by an interference fit.

[0041] See also Figure 3 As shown, a positioning boss 121 is provided on the contact surface between the fixing plate 12 and the seat shell 11. The positioning boss 121 corresponds to the position of the through hole opened on the surface of the fixing plate 12. After the straight plug socket 1 is assembled, the positioning boss 121 is pressed on the fixing bar 1321 to fix the seat signal unit 13.

[0042] See also Figure 5As shown, the grounding pin 132 is shaped as an elliptical structure and is manufactured by punching + rolling. A fixing strip 1321 is provided at the joint of the grounding pin 132, and a grounding fisheye 1322 is provided on the end face of the grounding pin 132 near the fixed end of the insertion rod 133. The grounding fisheye 1322 is used to terminate the "ground" hole of the PCB board to realize the electrical connection between the seat shell 11 and the PCB board, so that the "ground" of the seat shell 11 and the "ground" on the PCB board form a complete "ground" loop.

[0043] See also Figure 5 As shown, the fisheye segment 134 is fixed to the fixed end of the insertion rod 133. The fisheye segment 134 is punched, and one end of the fisheye segment 134 is assembled into the positioning groove 1331 opened at the fixed end of the insertion rod 133. After being assembled into place, the fisheye segment 134 is pressed against the step of the positioning groove 1331, and then the fisheye segment 134 is fixed to the insertion rod 133 by laser welding.

[0044] During installation, the fixed end of the insertion rod 133 is connected to the PCB board by crimping the fisheye section 134, and the punched fisheye section 134 and the four insertion rods 133 are welded together to form a component, thereby reducing the "short pile" effect in the signal transmission path and improving the high-speed transmission performance of the entire product.

[0045] To further enhance the tightness of the connection between the fisheye segment 134 and the rod 133, a second tin-through hole 1342 is defined at the connecting end of the fisheye segment 134 and the rod 133, while a first tin-through hole 1332 is defined at the fixed end of the rod 133. When the fisheye segment 134 is inserted into the positioning slot 1331, the second tin-through hole 1342 aligns with the first tin-through hole 1332, ensuring a dry solder joint. A plurality of spring clips 1333 are fixed to the mating end of the rod 133. In this embodiment, there are four spring clips 1333 formed by lathing, forming a four-lobed groove structure at the fixed end of the rod 133. This structure circumferentially elastically contacts the head signal unit 22 within the wiring plug 2. The elastic properties of the four-lobed groove structure are enhanced through a "shrinking + aging" process. When mated, the four elastic contact points are evenly distributed around the entire circumference, significantly improving the contact's resistance to vibration and shock in all directions.

[0046] See Figure 3 There are several seat channel cavities 111 in the seat shell 11, corresponding to several transmission paths. In addition, each seat channel cavity 111 has a corresponding channel boss 112 structure. After docking and plugging, the channel boss 112 is assembled into the inside of the docking end shell to ensure the integrity of the differential pair shielding.

[0047] A "convex rib" 114 is designed on the mating surface of the socket housing 11 to prevent reverse insertion during docking. The fixing plate 12 has several positioning bosses 121, each corresponding to a transmission path, and cooperates with the socket housing 11 to fix the socket signal unit 13 inside the socket 1.

[0048] Positioning posts 122 are designed on both sides of the mounting plate 12 to position and prevent reverse installation of the PCB when installing the in-line socket 1. The positioning posts 122 guide the relative positions of the contact and ground pins 132 before they mate with the PCB vias, preventing stress on the product due to misalignment of the fisheyes.

[0049] See also Figure 6 As shown, the wiring plug 2 includes a head shell 21 and a head signal unit 22. There are several head channel cavities 213 on the head shell 21. The head signal unit 22 is fixedly installed in the head channel cavity 213. Each head channel cavity 213 is independent of each other. The head channel cavity 213 is made of metal material to provide shielding for each transmission path.

[0050] See also Figure 6 As shown, the terminal plug 2 of the present invention further includes a tail cover 23 and a head locking attachment 24. The head locking attachment 24 includes a screw sleeve 241 and a screw 242. The screw sleeve 241 is fixedly inserted through both sides of the head shell 21. The tail cover 23 is sleeved on the outside of the flat wire 225. One side of the tail cover 23 contacts the shell 21 to form a glue potting cavity. The glue in the glue potting cavity solidifies, achieving the overall fixation of the internal structure.

[0051] See Figure 7 , head locking accessory holes 212 are opened on both sides of the head shell 21 for fixing the head locking accessory 24, that is, the screw sleeve 241 is fixedly inserted into the head locking accessory hole 212. The concave rib 211 structure is designed on the surface of the head shell 21, which cooperates with the convex rib 114 structure in the seat shell 11 to prevent reverse insertion.

[0052] See Figure 8 The head signal unit 22 includes a head base 221, a support plate 222, a pin 223, a shielding block 224, and a flat cable 225. One end of the pin 223 is welded to the core wire 2251 of the flat cable 225. The support plates 222 are arranged on both sides of the pin 223, and the two support plates 222 clamp the pin 223 from both sides. The support plates 222 have positioning protrusions 2221 and positioning grooves 2222. The positioning protrusions 2221 and positioning grooves 2222 have an interference fit. After the two support plates 222 are pressed together using a tool, the pin 223 is assembled into the head base 221.

[0053] The shielding block 224 is sleeved on the surface of the flat sheet wire 225. Specifically, a cable hole 2242 is opened inside the shielding block 224 for the flat sheet wire 225 to pass through. The flat sheet wire 225 has a core wire 2251 at one end passing through the cable hole 2242, so that the shielding block 224 is sleeved on the surface of the flat sheet wire 225. The shielding block 224 is made of metal.

[0054] The support plate 222 is disposed between the head base 221 and the shielding block 224. One side of the head base 221 abuts against one side of the support plate 222, and one side of the shielding block 224 abuts against the other side of the support plate 222. Specifically, the side of the support plate 222 closest to the head base 221 is a second mounting surface 2223, and the side of the head base 221 closest to the support plate 222 is a first mounting surface 2211. The second mounting surface 2223 mates with the first mounting surface 2211. The side of the shielding block 224 closest to the support plate 222 is a fourth mounting surface 2243. The side of the support plate 222 closest to the shielding block 224 is a fourth mounting surface 2243. The fourth mounting surface 2243 mates with the third mounting surface 2224. The shielding block 224 is electrically connected to the ground wire 2252. The shielding block 224 and the ground wire 2252 are fixed together by manual welding. The entire head signal unit 22 now forms a single assembly.

[0055] To facilitate the fixation of the head signal unit 22 and the head channel cavity 213 , interference protrusions 2241 are fixed on the surface of the shielding block 224 . When the shielding block 224 is located in the head channel cavity 213 , the interference protrusions 2241 are interference-fitted with the head channel cavity 213 .

[0056] During installation, the head signal unit 22 is assembled into each head channel cavity 213 in the head shell 21. During the assembly process, the interference protrusion 2241 structure on the shielding block 224 is interference fit with the head channel cavity 213. After the head signal unit 22 is assembled into place, it can be ensured to be fixed in the head shell 21.

[0057] See also Figure 2 and Figure 9As shown, a conductive rubber pad 14 is provided between the plug-in socket 1 and the wiring plug 2. When the head shell 21 and the base shell 11 are plugged and locked, the conductive rubber pad 14 is in a compressed state. The pin 223 is inserted into the mating end of the rod 133. Due to its elastic properties, the base shell contact surface 115 and the head shell contact surface 214 are fully in contact with the conductive rubber pad 14, ensuring good electrical conductivity between the interface of the base shell 11 and the interface of the head shell 21. Inside the plug-in socket 1, the positioning boss 121 of the fixing plate 12 presses on the fixing bar 1321 of the ground pin 132. At this point, the ground pin 132, the base shell 11, the conductive rubber pad 14, the head shell 21, the shielding block 224, and the ground wire 2252 of the flat wire 225 form a connected, 360° fully shielded structure. This complete shielding channel on the data transmission path achieves the effect of full-link shielding and avoids signal interference between each channel.

[0058] The head signal unit 22 and the seat signal unit 13 form a pinhole structure. The head signal unit 22 and the seat signal unit 13 transmit high-speed differential signals. The head signal unit 22 and the seat signal unit 13 are correspondingly arranged in the head channel cavity 213 and the seat channel cavity 111. Each cavity and the grounding pin 132 form a shielding channel to transmit the "ground" signal, wrap the contact inside the channel "ground", and reduce signal interference between different transmission paths.
