[0033] Please refer to Figures 1 to 11 As shown, the high-speed electrical connector of the present application is disclosed, including a connector part (not labeled) and a shielding cage 4. The connector part is correspondingly electrically connected to the mating circuit board. The shielding cage 4 is sleeved around the periphery of the connector part, and the shielding cage 4 itself is fixedly connected to the mating circuit board.

[0034] Please refer to Figures 4 to 7 As shown, the connector part includes an insulating body 3, a plurality of sheet-shaped insulating support members 1, and a plurality of signal terminals 2. The plurality of signal terminals 2 at least includes a differential signal terminal pair. The insulating body 3 is formed by injection molding of insulating material. Two open-shaped first slots 31 and second slots 32 are formed at the front end of the insulating body 3. The first slot 31 and the second slot 32 are arranged at intervals in the vertical direction.

[0035] Please refer to Figures 4 to 8 As shown, each of the sheet-shaped insulating support members 1 is generally a flat sheet body and is formed by injection molding of insulating material. Four signal terminals 2 are fixed in each of the sheet-shaped insulating support members 1. Each of the signal terminals 2 includes a tail portion 21 that protrudes downward outside the sheet-shaped insulating support member 1 and is used for connecting to the circuit board, a contact portion 22 that protrudes forward outside the sheet-shaped insulating support member 1 and is used for mating with the mating device, and a body portion 23 that connects the tail portion 21 and the contact portion 22 together. The body portion 23 forms a signal path for the signal terminal 2 between the tail portion 21 and the contact portion 22.

[0036] Please refer to Figures 3 to 7 As shown, the plurality of sheet-shaped insulating support members 1 are stacked in the left-right direction and then inserted and fixed into the insulating body 3 from front to back. The contact portions 22 of the two signal terminals 2 located above on the same sheet-shaped insulating support member 1 protrude into the first slot 31, and the contact portions 22 of the two signal terminals 2 located below protrude into the second slot 32. In the present application, the insulating body 3 and the plurality of sheet-shaped insulating support members 1 are collectively referred to as an insulating member (not labeled). The insulating body 3 and the plurality of sheet-shaped insulating support members 1 fixed with signal terminals 2 are collectively referred to as a module (not labeled).

[0037] Please refer to Figures 3 to 7 As shown, the connector part of the high-speed electrical connector shown in the present application further includes an insulating fastener 8. The insulating fastener 8 is fastened to both sides of the insulating body 3 from front to back, and the plurality of sheet-shaped insulating support members 1 are framed therein (enclosed therein). In the present application, the insulating fastener 8 is located at the lower rear end of the module.

[0038] Please refer to Figures 1 to 7As shown, the shielding cage 4 is made of a metal plate. At the front end of the shielding cage 4, an insertion opening 41 is formed corresponding to the first slot 31 and the second slot 32. Along the insertion direction, a specific distance is spaced between the insertion opening 41 of the shielding cage 4 and the front edge of the insulating body 3, and an insertion space 40 is formed. The shielding cage 4 includes a top plate 401, a bottom plate 402 disposed opposite to the top plate 401 and located directly below the top plate 401, two side plates 403 connecting the two sides of the top plate 401 and the bottom plate 402, and a rear end plate 42 located at the rear end position. The top plate 401, the bottom plate 402, the two side plates 403, and the rear end plate 42 form a generally cuboid metal cage with an opening facing forward, and the insertion opening 41 is formed in the front. An opening-shaped structure is formed between the rear edge position of the bottom plate 402 and the rear end plate 42, so that the end position of the insertion space 40 communicates downward with the outside, and the tail 21 of the signal terminal 2 of the connector part protrudes downward from the rear position of the bottom plate 402 out of the shielding cage 4.

[0039] Please refer to Figures 3 to 5 As shown, the shielding cage 4 further includes two spacer plates 44. The two spacer plates 44 divide the insertion space 40 into three regions stacked in the up and down direction. The first slot 31 corresponds to the upper region of the three regions, and the second slot 32 corresponds to the lower region of the three regions. The high-speed electrical connector further includes a light guide member 5. The light guide member 5 extends longitudinally along the insertion and extraction direction. The light guide member 5 is clamped between the two spacer plates 44 (that is, the middle region of the three regions). The rear edge of the two spacer plates 44 is correspondingly inserted and fixed in the insulating body 3, and the left and right side edges of the two spacer plates 44 are correspondingly snap-fixed to the two side plates 403 (specifically, snap holes (not marked) are formed at corresponding positions on the two side plates 403, and the two spacer plates 44 are bent to form snap pieces (not marked), and the snap pieces are bent and limited after being inserted into the snap holes).

[0040] Please refer to Figures 3 to 5 As shown, the light guide member 5 is limited by the two spacer plates 44 in the up and down direction and the left and right direction perpendicular to the insertion and extraction direction. Wherein, limiting buckles 442 are bent on both sides of the spacer plate 44 along the left and right direction. The limiting buckles 442 are limited on the left and right sides of the light guide member 5. The limiting buckles 442 form precise positioning for the light guide member 5. By setting the limiting buckles 442, the size difference or tolerance between the light guide member 5 and the middle region of the three regions can be effectively absorbed. Specific examples are as follows: when the size of the light guide member 5 in the left and right direction is much smaller than the width of the middle region of the three regions, the light guide member 5 can be accurately positioned. Another example is: when the widths (widths in the left and right direction) of each part of the light guide member 5 in the front and rear direction are inconsistent, the light guide member 5 can be accurately positioned at each position in the front and rear direction.

[0041] Please refer toFigures 3 to 7 As shown, the high-speed electrical connector of the present application further includes a metal support member 7. The metal support member 7 is fixed to the insulating body 3 and is located between the first slot 31 and the second slot 32 of the insulating member in the up-and-down direction, and is preferably located between the two spacer plates 44. The metal support member 7 limits the optical waveguide member 5 in the plugging and unplugging direction. Specifically, the metal support member 7 extends backward to form two mounting pieces 71. The two mounting pieces 71 are buckled on the left and right side surfaces of the insulating body 3. The rear end of the optical waveguide member 5 extends backward and downward to form two support feet 51. The two support feet 51 are correspondingly clamped on the outer side surfaces of the two mounting pieces 71 of the metal support member 7. At least two limiting pieces 711 are formed on each mounting piece 71 extending in the left-and-right direction. The limiting pieces 711 limit the optical waveguide member 5 in the plugging and unplugging direction.

[0042] In addition, a cantilever-shaped elastic arm 712 is formed on each mounting piece 71 extending backward and obliquely. The elastic arm 712 is in elastic contact with the shielding cage 4. The metal support member 7 extends backward with two support pieces 72. The two support pieces 72 are arranged oppositely in the up-and-down direction. The two support pieces 72 correspondingly abut between the two spacer plates 44. An elastic piece 721 is formed on each support piece 72. The elastic piece 721 is in elastic contact with the spacer plate 44.

[0043] In the present application, the metal support member 7 is first installed on the optical waveguide member 5 from bottom to top, then the optical waveguide member 5 fixed with the metal support member 7 is assembled from back to front between the two spacer plates 44, and finally the two spacer plates 44 fixed with the metal support member 7 and the optical waveguide member 5 are inserted and fixed on the insulating body 3 from front to back.

[0044] Please refer to Figure 7 and Figure 8 As shown, on each sheet-shaped insulating support member 1, an air channel 11 is formed through at a position close to the signal terminal 2, and no air channel 11 is provided between at least two adjacent signal terminals 2. In this embodiment, in the direction from bottom to top, no air channel 11 is provided between the first signal terminal 2 (A1) and the second signal terminal 2 (A2). An air channel 11 is provided between the second signal terminal 2 (A2) and the third signal terminal 2 (A3). An air channel 11 is provided between the third signal terminal 2 (A3) and the fourth signal terminal 2 (A4).

[0045] Of course, in other embodiments, it can also be designed that, in the direction from bottom to top, an air channel 11 is provided between the first signal terminal 2 (A1) and the second signal terminal 2 (A2). No air channel 11 is provided between the second signal terminal 2 (A2) and the third signal terminal 2 (A3). An air channel 11 is provided between the third signal terminal 2 (A3) and the fourth signal terminal 2 (A4).

[0046] Certainly, in other embodiments, it can also be designed that an air channel 11 is provided between the first signal terminal 2(A1) and the second signal terminal 2(A2) in the direction from bottom to top. An air channel 11 is provided between the second signal terminal 2(A2) and the third signal terminal 2(A3). No air channel 11 is provided between the third signal terminal 2(A3) and the fourth signal terminal 2(A4).

[0047] Certainly, in other embodiments, the adjacent signal terminals 2 without the air channel 11 can also be between the first signal terminal 2(A1) and the second signal terminal 2(A2) and between the third signal terminal 2(A3) and the fourth signal terminal 2(A4).

[0048] In this application, not providing the air channel 11 between two adjacent signal terminals is mainly considered for easy injection molding and improving the overall structural strength of the sheet-shaped insulating support 1. Certainly, providing the air channel 11 at the adjacent position of individual signal terminals 2 is to help reduce crosstalk (air is a medium with a smaller loss than the insulating material forming the sheet-shaped insulating support 1), which helps improve high-frequency signal transmission.

[0049] Please refer to Figure 7 and Figure 8 As shown, the air channel 11 has the same extension trend as the body part 23 of the adjacent signal terminal 2. The body part 23 of each signal terminal 2 is partially exposed in the air, and an air groove 10 is formed on the corresponding sheet-shaped insulating support 1. The body part 23 of the signal terminal 2 includes a horizontally extending horizontal part 231, a vertically extending vertical part 232, and an inclined part 233 connecting the horizontal part 231 and the vertical part 232. The air channel 10 includes a part adjacent to the horizontal part 231, a part adjacent to the vertical part 232, and a part adjacent to the inclined part 233. The air groove 10 includes a part that exposes at least part of the horizontal part 231 in the air, a part that exposes at least part of the vertical part 232 in the air, and a part that exposes at least part of the inclined part 233 in the air.

[0050] Please refer to Figure 9 and Figure 10As shown, this is the second embodiment of the high-speed electrical connector of the present application. In the second embodiment, a heat dissipation interval 400' is formed between a partial position on the rear end surface of the insulating member (composed of an insulating body 3' and a plurality of sheet-shaped insulating supports 1') and the rear end plate 42'. A heat dissipation hole 43' is formed through the rear end plate 42' corresponding to the position of the heat dissipation interval 400'. Specifically, a partial area on the rear surface of the plurality of sheet-shaped insulating supports 1' forms the heat dissipation interval 400' between it and the rear end plate 42'. More specifically, the heat dissipation interval 400' is formed between the rear surface of the plurality of sheet-shaped insulating supports 1' except for the part covered by the insulating fastener 8' and the rear end plate 42'. The heat dissipation interval 400' and the heat dissipation hole 43' can improve air circulation, thereby improving the heat dissipation performance. In the present application, the high-speed design of the insulating fastener 8 in the up-and-down direction is relatively small, in order to make the heat dissipation interval 400' as large as possible. In the present application, along the up-and-down direction, the height of the heat dissipation interval 400' is not less than twice that of the insulating fastener 8', and preferably the height of the heat dissipation interval 400' is not less than three times that of the insulating fastener 8'.

[0051] Please refer to Figures 3 to 5 As shown, the high-speed electrical connector of the present application further includes a light shielding member 6. Two light guide columns 52 are formed at the front end position of the light guide member 5 and are arranged at intervals along the left-right direction. The light shielding member 6 is fixed on the two light guide columns 52, exposing the front end surfaces of the two light guide columns 52 and covering the peripheries of the two light guide columns 52. A plurality of ventilation holes 60 penetrating in the front-back direction are formed on the light shielding member 6. The ventilation holes 60 connect the front end of the middle area (the area formed between two partition plates) in the three areas to the outside for better heat dissipation.

[0052] Please refer to Figures 1 to 5 As shown, two connector parts of the high-speed electrical connector 1 of the present application are provided and are arranged adjacent to each other along the left-right direction. The light guide member 5 is fixed on each of the connector parts. The shielding cage 4 includes a partition plate 45. The partition plate 45 is clamped between the two connector parts. The partition plate 45 divides the insertion space 40 formed by the shielding cage 4 into two intervals along the left-right direction. The partition plate 45 separates the light guide members 5 of the two connector parts at the full length of the light guide member 5 to prevent light leakage between the light guide members 5 corresponding to the two connector parts.

[0053] Please refer to Figure 7 、 Figure 8 and Figure 11As shown, each of the sheet-shaped insulating supports 1 is formed with a thin portion 14 at the connection position between the body portion 23 and the tail portion 21. An air groove 140 is formed at the position of the thin portion 14 between two adjacent sheet-shaped insulating supports 1. The air groove 140 is communicated with the air groove 10. The width of the air groove 140 is wider than the body portion 23 of the signal terminal 2 at the position of the air groove 140. The signal terminal 2 is not exposed to the air groove 140. The air channel 11 is not communicated with the air groove 140. The setting of the air groove 140 is beneficial to improving impedance continuity and has a favorable impact on the signal integrity of the signal terminal 2. In the present application, the air groove 140 is formed on one side surface of each of the sheet-shaped insulating supports 1 in the left-right direction.
