Please refer to fig. 1 to 14, which illustrate an embodiment of the present invention. As shown in fig. 1 to 5, the present embodiment discloses an electrical connector 100 for detachably plugging in a mating connector 200 along a plugging direction S, and the electrical connector 100 is, for example, a high-speed (high frequency) connector applied to a server or a switch, but the present invention is not limited thereto. For the convenience of description, the electrical connector 100 defines a first direction D1 and a second direction D2 perpendicular to the plugging direction S, and the first direction D1 and the second direction D2 are perpendicular to each other.
As shown in fig. 6 to 8, the electrical connector 100 includes a housing 1 and a plurality of transmission pieces 2 inserted into the housing 1 along a plugging direction S, and the plurality of transmission pieces 2 are aligned along a first direction D1 in the present embodiment. It should be noted that, although the transmission sheet 2 is described with the housing 1 in the present embodiment, in other embodiments not shown in the present invention, the transmission sheet 2 may be applied separately (e.g. vending) or used with other components.
The housing 1 in this embodiment comprises an insulating outer shell 11 and an electrically conductive inner shell 12 disposed within the insulating outer shell 11. The insulating outer shell 11 and the conductive inner shell 12 may be in a non-separable single-piece structure or a separable two-piece structure according to design requirements, which is not limited herein. It should be noted that any housing not including the conductive inner housing is different from the housing 1 according to the present embodiment.
The insulating housing 1 includes a substantially rectangular insertion portion 111, a positioning plate 112 extending from the top end of the insertion portion 111 along the insertion and extraction direction S, and a plurality of guide posts 113 formed on the top and bottom surfaces of the insertion portion 111 in a staggered manner. The positioning plate 112 is used for fastening and positioning the plurality of transmission sheets 2, the plurality of guiding columns 113 are used for positioning the mating connector 200, and the number of the plurality of guiding columns 113 is two in the present embodiment, but the invention is not limited thereto.
In addition, as shown in fig. 8 and 9, the (plug portion 111 of the) insulating housing 11 includes an outer mating surface 1111 and an inner mating surface 1112, and the outer mating surface 1111 is further away from the positioning plate 112 than the inner mating surface 1112. The insulating housing 11 has a plurality of terminal grooves 1113 formed in a penetrating manner (and arranged in a matrix manner) along the insertion/extraction direction S, and the plurality of terminal grooves 1113 are formed in the present embodiment so as to extend from the outer mating surface 1111 (along the insertion/extraction direction S) to the inner mating surface 1112. And the insulating housing 11 is further recessed from the inner mating surface 1112 to form an inner mating groove 1114 that communicates with portions of the plurality of terminal grooves 1113.
As shown in fig. 7 and 8, the conductive inner shell 12 may be an electroplated plastic inner shell, a conductive plastic inner shell, or a metal inner shell according to design requirements, and the metal inner shell may be made by metal injection molding or powder metallurgy, but the invention is not limited thereto. In this embodiment, the conductive inner housing 12 is formed with a plurality of frame openings 121 communicating with the plurality of terminal grooves 1113, and the number of the plurality of frame openings 121 is smaller than the number of the plurality of terminal grooves 1113.
Further, the conductive inner housing 12 is substantially fence-shaped in the present embodiment, the plurality of frame openings 121 are arranged in a staggered manner in the first direction D1, and the plurality of frame openings 121 are arranged in a plurality of rows parallel to the second direction D2. In this embodiment, the plurality of openings 121 includes a plurality of closed openings 1211 and a plurality of open openings 1212, and the plurality of open openings 1212 are located at the outer edge of the inner conductive shell 12; that is, the plurality of open bezel 1212 surrounds the plurality of closed bezel 1211.
In addition, each of the closed frame openings 1211 is connected to at least two of the terminal slots 1113, and each of the open frame openings 1212 is connected to at least one of the terminal slots 1113, and the number of the terminal slots 1113 connected to each of the closed frame openings 1211 is not less than the number of the terminal slots 1113 connected to any one of the open frame openings 1212. In the present embodiment, each of the closed frame openings 1211 is connected to the adjacent three terminal slots 1113 arranged along the second direction D2, and the open frame openings 1212 can be connected to one terminal slot 1113 or two or three adjacent terminal slots 1113 arranged along the second direction D2.
In more detail, the conductive inner shell 12 includes a exposed portion 122 and an embedded portion 123, and the conductive inner shell 12 is inserted and fixed in the inner assembling groove 1114 by the embedded portion 123; that is, the exposed portion 122 protrudes from the inner set groove 1114 (and/or the inner set surface 1112). Wherein, the embedded part 123 and the inner assembling groove 1114 can be in interference fit, so that the conductive inner shell 12 is firmly installed on the insulating outer shell 11.
Further, as shown in fig. 7 to 9, the housing 1 is formed with a plurality of interference ribs 114 in the plugging portion 111 of the insulating housing 11, and the positions and shapes of the interference ribs 114 can be adjusted and changed according to design requirements, so that the conductive inner housing 12 can be fixed in the insulating housing 11 with the plurality of interference ribs 114 (but can be separated) but the invention is not limited thereto. For example, in other embodiments of the invention not shown, the plurality of interference ribs 114 may also be buried portions 123 formed in the inner conductive shell 12.
In addition, the conductive inner shell 12 includes a serial connection surface 1221 far from the outer mating surface 1111, and the serial connection surface 1221 is located on the exposed portion 122 and far from the buried portion 123. The serial connection surface 1221 and the inner connection surface 1112 are separated by a step G in the plugging direction S, and the step G is illustrated with at least 5 millimeters (mm) in the present embodiment, but the invention is not limited thereto. Accordingly, the series connection surface 1221 and the inner connection surface 1112 are separated by the step G in the plugging direction S, so as to effectively achieve the effect of optimizing the characteristic impedance.
Further, the serial surface 1221 of the inner housing 12 is concavely formed with a plurality of serial slots 1222 disposed at intervals and electrically coupled, and each serial slot 1222 may be disposed at a corner of one of the frame openings 121, and any interference rib 114 is preferably disposed adjacent to one of the serial slots 1222; that is, the positions of the interference ribs 114 may be in the insertion portion 111 of the insulating housing 11 disposed corresponding to the corner of one of the frame openings 121 (e.g., one interference rib 114 may be disposed in the insertion portion 111 of the insulating housing 11 corresponding to the upper right corner or the lower left corner of each of the frame openings 121), and the positions of the interference ribs 114 disposed corresponding to the corners may be arranged in a plurality of rows along (or parallel to) the same direction, but the present invention is not limited thereto. For example, in other embodiments not shown in the present disclosure, the positions of the interference ribs 114 may be two corners respectively corresponding to opposite angles of the frame openings 121, for example: each of the upper right and lower left corners of each of the frame openings 121 is provided with an interference rib 114. In this embodiment, any one of the serial grooves 1222 is concavely disposed from the exposed portion 122 to the embedded portion 123, and a communication opening 1223 is formed in any one of the serial grooves 1222 to communicate with the corresponding frame opening 121 in the first direction D1.
The conductive inner shell 12 is orthographically projected (along the plugging direction S) toward the inner assembling surface 1112 to form a projection area on the inner assembling surface 1112, which covers 30% -50% of the inner assembling surface 1112; that is, the inner assembling surface 1112 has a plurality of exposed areas 1115 not covered by the projection area, and the plurality of exposed areas 1115 are also located at the portion of the inner assembling surface 1112 not recessed to form the inner assembling groove 1114.
Wherein, the position of each exposed area 1115 corresponds to two adjacent terminal slots 1113 arranged along the second direction D2, and each exposed area 1115 is located in one frame opening 121; that is, any exposed region 1115 does not span two openings 121 in the present embodiment. Further, any exposed area 1115 of the inner assembling surface 1112 is formed with a notch 1116 along the inserting and extracting direction S, and any notch 1116 corresponds to the communicating inner assembling groove 1114, and any notch 1116 has a length of at least 0.5 mm in the second direction D2; that is, at least one side of the notch 1116 in the second direction D2 has a length of at least 0.5 mm, and the end face of the notch 1116 (in any exposed region 1115 of the inner set of joints 1112) may be rectangular or trapezoidal in shape. Wherein the notches 1116 are parallel to two sides in the second direction D2 and have the same or different lengths. Further, the end face of the notch 1116 has a trapezoid shape, and the two sides of the notch 1116 parallel to the second direction D2 may have sides with shorter lengths closer to the terminal groove 1113 (or the sides away from the frame opening 121), but the invention is not limited thereto. Accordingly, by forming the notch 1116 in the insertion/extraction direction S in any exposed region 1115 of the inner joint surface 1112, the effect of optimizing the characteristic impedance can be effectively achieved.
It should be noted that, although the insulating outer shell 11 and the conductive inner shell 12 are described as having the above technical features in the present embodiment, the specific structure of the insulating outer shell 11 and the conductive inner shell 12 may include only some of the above technical features according to the design requirement. For example, in other embodiments of the invention not shown, any of the exposed areas 1115 of the insulating housing 11 may not be notched 1116; alternatively, the conductive inner case 12 may not be formed with the plurality of frame openings 121; alternatively, the serial surface 1221 of the inner conductive shell 12 may not have the step G formed thereon compared to the inner joint surface 1112; alternatively, the case 1 is not formed with the plurality of interference ribs 114.
As shown in fig. 6, the plurality of transmission plates 2 are inserted into the housing 1 along the inserting and extracting direction S and fastened to the positioning plate 112 of the insulating housing 11, and since the plurality of transmission plates 2 in the present embodiment include two structures, but the component structures thereof are substantially the same, for convenience of understanding the present embodiment, only the structure of a single transmission plate 2 will be described below, and then the connection relationship between the plurality of transmission plates 2 will be described in time. For example, in other embodiments of the invention not shown, the electrical connector 100 may also employ multiple transmission sheets 2 with completely different or identical component architectures.
As shown in fig. 10 to 12, the transmission sheet 2 includes a substantially rectangular insulating frame 21, a plurality of signal terminals 22 and a plurality of ground terminals 23 fixed to the insulating frame 21, and a shielding sheet 24 to which the insulating frame 21 is attached.

In more detail, the plurality of ground terminals 23 are disposed in an alternating manner with the plurality of signal terminals 22, and two signal terminals 22 (i.e., a differential signal pair) that can be commonly used to transmit differential signals are disposed between any two adjacent ground terminals 23 or adjacent to any one ground terminal 23. The plurality of ground contact sections 232 are aligned with the plurality of signal contact sections 222 along the second direction D2, and the plurality of ground mounting sections 233 are aligned with the plurality of signal mounting sections 223 along the plugging direction S.
It should be noted that, although the ground embedded section 231 and the signal embedded section 221 are embedded in the insulating frame 21, the ground embedded section 231 and the signal embedded section 221 may be exposed outside the insulating frame 21 in a local area, so as to facilitate the impedance adjustment of the transmission sheet 2, and the part of the ground embedded section 231 exposed outside the insulating frame 21 may be inserted and connected by the shielding sheet 24.
The shielding sheet 24 is a single piece structure formed by stamping a single metal sheet in the present embodiment, and the shielding sheet 24 includes a sheet body 241, a plurality of inner arms 242 bent and extended from the sheet body 241, a plurality of fixing arms 243 extended from the sheet body 241, and a plurality of elastic arms 244 respectively extended from the plurality of fixing arms 243 toward the sheet body 241, but the invention is not limited thereto. For example, in other embodiments of the invention not shown, the shield blades 24 may omit the inner arms 242 and/or the resilient arms 244.

More specifically, the plurality of elastic arms 244 are formed by bending and extending from the fixed arm 243 to which they are connected (respectively) in the first direction D1 or in a plane formed by the first direction D1 and the insertion/extraction direction S substantially obliquely toward the corresponding side notch 2411, and the plurality of elastic arms 244 are located on the same side of the sheet body 241 as the plurality of inner arms 242.
Further, in the present embodiment, the shielding sheet 24 is riveted and fixed to one side of the insulating frame 21 by the sheet body 241, so that the sheet body 241 shields the signal embedded sections 221 of the plurality of signal terminals 22 in the first direction D1, thereby providing a perfect signal shielding effect. The plurality of inner connecting arms 242 are respectively inserted into the grounding embedded sections 231 of the plurality of grounding terminals 23 (for example, the grounding embedded sections 231 exposed outside the insulating frame 21), so that the shielding sheet 24 and the plurality of grounding terminals 23 form a common ground connection.
In addition, the plurality of fixing arms 243 are arranged in another row along the second direction D2, which is spaced apart from the row in which the plurality of ground contact sections 232 and the plurality of signal contact sections 222 are arranged. Wherein the number of the plurality of fixing arms 243 of the shield sheet 24 is less than or equal to the number of the plurality of ground terminals 23; that is, in one transfer sheet 2, the number of the plurality of fixing arms 243 of the shield sheet body 24 may be less than or equal to the number of the plurality of ground terminals 23; in one transmission sheet 2 of the present embodiment, the number of the plurality of fixing arms 243 of the shielding sheet 24 is equal to the number of the plurality of ground terminals 23, and each fixing arm 243 and the corresponding elastic arm 244 correspond to one ground contact section 232 along the first direction D1, and the connection 245 of each fixing arm 243 and the corresponding elastic arm 244 protrudes out of the ground contact 2321 of the corresponding ground contact section 232 in the plugging direction S (e.g. the bending of the ground contact section 232 in fig. 13).
In more detail, in order to make each fixing arm 243 have a preferable structural strength to facilitate the swing of the corresponding elastic arm 244 for the fixing use and to effectively support, each fixing arm 243 of the present embodiment adopts the following structural design, but the present invention is not limited thereto.
As shown in fig. 11, 13, and 14, each fixing arm 243 includes a free end 2431 remote from the sheet body 241, a supporting portion 2432 connected to the sheet body 241 (e.g., corresponding to the inner wall of the edge cutout 2411), and a connecting portion 2433 connecting the supporting portion 2432 and the free end 2431. In each of the fixing arms 243 of the present embodiment, a first thickness T1 of the supporting portion 2432 in the first direction D1 is greater than a second thickness T2 of the connecting portion 2433 or the free end portion 2431 in the first direction D1. The ratio of the first thickness T1 divided by the second thickness T2 is preferably 1.1-1.5, but the invention is not limited thereto.
Each elastic arm 244 is formed by extending from the free end 2431 of the corresponding fixed arm 243 in the present embodiment, and each elastic arm 244 is adjacent to the connecting portion 2433 and the supporting portion 2432 of the corresponding fixed arm 243; that is, one side edge of the free end 2431 of each fixed arm 243 is simultaneously connected to the connecting portion 2433 and the corresponding elastic arm 244.
The free end 2431 of each fixing arm 243 further includes two interference regions 2434 (respectively located at opposite sides) respectively adjacent to the connecting portion 2433 and the corresponding elastic arm 244, but the invention is not limited thereto. For example, each fixed arm 243 (or free end 2431) may also include at least one interference region 2434. When each fixing arm 243 is inserted into the conductive inner housing 12 with the free end 2431, the fixing arm 243 is further fixed in the conductive inner housing 12 by the interference area 2434. In addition, in each fixed arm 243, the maximum distance between the two interference regions 2434 of the free end 2431 is greater than the length of the side edge of the free end 2431 (connected to the connecting portion 2433 and the corresponding elastic arm 244).
Furthermore, the free end 2431 of each fixing arm 243 protrudes in the insertion direction S beyond the ground contact 2321 of the corresponding ground contact section 232, and the free end 2431 of each fixing arm 243 does not protrude in the insertion direction S beyond the terminal edge of the corresponding ground contact section 232. Wherein the free end 2431 of each fixed arm 243 preferably protrudes in the insertion-and-extraction direction S by at least 0.5 millimeters (mm) from the ground contact 2321 of the corresponding ground contact section 232, although the invention is not limited thereto.
Accordingly, the transmission sheet 2 disclosed in the present embodiment adopts a completely new structure (e.g. the plurality of ground contact sections 232 and the plurality of signal contact sections 222 are arranged in a row, the plurality of fixed arms 243 are arranged in another row, each free end 2431 protrudes from the corresponding ground contact 2321, and the connection portion 245 between each fixed arm 243 and the corresponding elastic arm 244 protrudes from the corresponding ground contact 2321), thereby expanding the space for subsequent development and design of the transmission sheet 2.

As shown in fig. 4 to 7, the plurality of signal contact sections 222 and the plurality of ground contact sections 232 of the plurality of transmission plates 2 are respectively inserted into the plurality of terminal grooves 1113 of the housing 1 (along the insertion/extraction direction S), and the plurality of fixing arms 243 of the plurality of transmission plates 2 are respectively inserted and fixed into the housing 1 with their free end portions 2431.
Wherein (the free end 2431 of each of the fixed arms 243 and the corresponding ground contact section 232 of the plurality of transmission sheets 2 are inserted and fixed in the conductive inner housing 12 to be electrically coupled with each other (e.g., the free end 2431 of each of the fixed arms 243 is fixed to the conductive inner housing 12 by at least one interference region 2434 thereof to be electrically coupled with each other), and the free end 2431 of each of the fixed arms 243 is separated from the ground contact 2321 of the corresponding ground contact section 232 in the first direction D1 by the conductive inner housing 12; that is, the free end 2431 of each fixed arm 243 does not contact the corresponding ground contact segment 232.
Further, the grounding contact sections 232 and the fixing arms 243 of the plurality of transmission plates 2 are electrically coupled to each other by being inserted into the serial surface 1221 of the conductive inner housing 12. In the present embodiment, the fixing arms 243 of the plurality of transport plates 2 are respectively inserted and fixed in the serial slots 1222 (e.g. each fixing arm 243 is fixed in the corresponding serial slot 1222 by its interference area 2434), and each elastic arm 244 is located in one serial slot 1222 and its communication port 1223. Further, one end of each elastic arm 244 adjacent to the connecting portion 2433 of the corresponding fixing arm 243 is located in a serial slot 1222, and the other end of each elastic arm 244 adjacent to the supporting portion 2432 of the corresponding fixing arm 243 is exposed outside the serial surface 1221 of the inner housing 12, but the invention is not limited thereto.

In addition, in the electrical connector 100 of the present embodiment, all the grounding components (such as the plurality of grounding terminals 23 and the plurality of shielding plates 24) can be electrically coupled to each other through the serial connection surface 1221 of the conductive inner housing 12, so that the grounding components and/or the plurality of transmission plates 2 can achieve a common grounding effect, and further the plurality of signal terminals 22 can be effectively prevented from being interfered by external signals.
In another aspect, two adjacent signal contact sections 222 of any one of the transmission plates 2 are located in an exposed area 1115 and located in one of the openings 121 of the inner housing 12 in the present embodiment, and are surrounded by at least 180 degrees by the corresponding opening 121 on a plane perpendicular to the plugging direction S. Wherein two adjacent signal contact sections 222 of any one transmission sheet 2 are surrounded by the corresponding closed frame opening 1211 or the corresponding open frame opening 1212 by at least 180 degrees in a plane. Accordingly, the electrical connector 100 can further enhance the signal transmission performance of the plurality of signal terminals 22 through the position matching between the plurality of frame openings 121 of the conductive inner housing 12 and the plurality of signal terminals 22.
Two adjacent signal contact sections 222 of any one transmission sheet 2 may be disposed in one frame opening 121 (e.g., a closed frame opening 1211); alternatively, one of the frame openings 121 (e.g., the closed frame opening 1211) may be provided with the ground contact section 232 of any one of the transmission plates 2 and the signal contact section 222 adjacent thereto; alternatively, only a single ground contact segment 232 may be provided within one bezel 121 (e.g., an open bezel 1212); alternatively, only two signal terminals 22 (i.e., one differential signal pair) may be provided within one bezel 121 (e.g., an open bezel 1212). The signal contact section 222 located in the closed frame 1211 or the open frame 1212 has a better shielding effect, and the signal terminal 22 has better signal transmission performance.

In the present embodiment, any one of the elastic arms 244 and its corresponding ground contact segment 232 are used to press and abut (e.g., to substantially clamp) the corresponding terminal 201 of the mating connector 200 in different directions. Each of the elastic arms 244 swings toward the corresponding side cutout 2411 when being abutted against the corresponding terminal 201 of the mating connector 200 (see fig. 11).
Accordingly, the electrical connector 100 disclosed in the present embodiment includes the plurality of grounding terminals 23 and the plurality of shielding sheets 24 that can be electrically coupled to each other and commonly grounded through the conductive inner housing 12, and further connected to the mating connector 200 (e.g. each of the elastic arms 244 and the corresponding grounding contact 2321 abut against the grounding terminal 201 of the mating connector 200), and the grounding terminals 201 of the mating connector 200 are electrically coupled to each other through the conductive inner housing 12, so that the elastic arms 244, the grounding contacts 2321, the grounding terminals 201 and the conductive inner housing 12 are commonly grounded, so that all grounding components of the electrical connector 100 and the mating connector 200 achieve a commonly grounded effect, thereby effectively ensuring the quality and the performance of signal transmission.
