[0048] Please refer to Figures 2 to 5 . Figure 2 and Figure 4 are respectively three-dimensional structural diagrams of the first perspective and the second perspective of the high-speed connector 100 in the embodiments of the present application. Figure 3 is Figure 2 an enlarged view of the partial view H1 in Figure 5 is Figure 4 an enlarged view of the partial view H2 in

[0049] In some embodiments, the high-speed connector 100 includes a housing 200 and a signal transmission member 300. The housing 200 has a receiving cavity 201 with one side open. At least part of the signal transmission member 300 is inserted into the receiving cavity 201 from the open end of the housing 200 and is snap-connected to the housing 200 near the open end. The housing 200 can elastically deform outward relative to the signal transmission member 300 at the snap connection, thereby releasing the snap connection.

[0050] In some embodiments, the housing 200 includes an end portion 205, a first side portion 207, a second side portion 209, a third side portion 211, and a fourth side portion 213. The first side portion 207 and the second side portion 209 are respectively connected to two ends of the end portion 205 in the Y-axis direction. The third side portion 211 and the fourth side portion 213 are respectively connected to two ends of the end portion 205 in the X-axis direction. The first side, the second side portion 209, the third side portion 211, and the fourth side portion 213 respectively extend from the edge of the end portion 205 along the positive direction of the Z-axis, and have different extension lengths, and enclose a receiving cavity 201 that is open along the positive direction of the Z-axis. The specific structure of the housing 200 is not limited thereto. In some embodiments, the material of the housing 200 is plastic.

[0051] In Figures 2 to 5 the illustrated embodiment, only two signal transmission members 300 are shown. Generally, the number of signal transmission members 300 is greater than two, for example, 10, and multiple signal transmission members 300 are arranged in sequence along the X-axis. The housing 200 is fixedly connected to multiple signal transmission members 300 respectively, so that the relative positions of the multiple signal transmission members 300 are fixed, thereby facilitating the assembly of the multiple signal transmission members 300 to the single board 520 or the backplane 510.

[0052] Please refer to Figure 6 . Figure 6 is a three-dimensional exploded view of the signal transmission member 300 in the embodiment of the present application.

[0053] In some embodiments, the signal transmission member 300 includes an insulating body 307, a plurality of conductive terminals 309, a first shielding member 311, and a second shielding member 313. The plurality of conductive terminals 309 are embedded in the insulating body 307, one end is exposed to be electrically connected to the single board 520 or the backplane 510, and the other end is exposed to be electrically connected to the conductive terminals 309 in another high-speed connector 100. The material of the insulating body 307 can be plastic. The conductive terminals 309 and the insulating body 307 can be integrally formed by injection molding. The insulating body 307 is generally in a flat plate shape. The first shielding member 311 is fixedly arranged on one side of the insulating body 307, and the second shielding member 313 is fixedly arranged on the other side of the insulating body 307. The first shielding member 311 and the second shielding member 313 can be made of a metal material. The signal transmission member 300 is used for transmitting signals. The specific structure of the signal transmission member 300 is not limited thereto.

[0054] In some embodiments, the inner wall surface of the housing 200 is provided with a guiding groove, the guiding groove extends from the open end of the housing 200 toward the opposite side, and the bottom of the guiding groove has a clamping groove. The signal transmission member 300 has a buckle. At least a part of the signal transmission member 300 is inserted into the receiving cavity 201 under the guidance of the guiding groove, and the buckle is in concave-convex fit with the clamping groove so that the signal transmission member 300 is snap-connected to the housing 200.

[0055] Specifically, the surface of the first side portion 207 facing the second side portion 209 has a first guiding groove 215. The first guiding groove 215 extends along the reverse direction of the Z-axis from one end of the first side portion 207 departing from the end portion 205. The opening of the first guiding groove 215 faces the second side portion 209. The number of the first guiding grooves 215 is multiple. The first guiding grooves 215 correspond to the signal transmission members 300 one by one. The surface of the second side portion 209 facing the first side portion 207 has a second guiding groove 217. The second guiding groove 217 extends along the reverse direction of the Z-axis from one end of the second side portion 209 departing from the end portion 205. The opening of the second guiding groove 217 faces the first side portion 207. The number of the second guiding grooves 217 is multiple. The second guiding grooves 217 correspond to the signal transmission members 300 one by one. The signal transmission members 300 are clamped in the corresponding first guiding grooves 215 and second guiding grooves 217, and are pressed against the housing 200 along the reverse direction of the Z-axis.

[0056] Specifically, the first side portion 207 has a first clamping groove 219, and the first clamping groove 219 penetrates through the first side portion 207 along the Y-axis. The number of the first clamping grooves 219 is multiple. The first clamping grooves 219 correspond to the signal transmission members 300 one by one. The second side portion 209 has a second clamping groove 221, and the second clamping groove 221 penetrates through the second side portion 209 along the Y-axis. The number of the second clamping grooves 221 is multiple. The second clamping grooves 221 correspond to the signal transmission members 300 one by one. The first buckle 303 can be a part of the insulating body 307. The first buckle 303 of the signal transmission member 300 is inserted into the corresponding first clamping groove 219 along the reverse direction of the Y-axis, and is used to abut against the first side portion 207 along the Z-axis direction, so as to limit the signal transmission member 300 from exiting the accommodation cavity 201 along the positive direction of the Z-axis. The second buckle 305 can be a part of the insulating body 307. The second buckle 305 of the signal transmission member 300 is inserted into the corresponding second clamping groove 221 along the Y-axis, and is used to abut against the first side portion 207 along the Z-axis direction, so as to limit the signal transmission member 300 from exiting the accommodation cavity 201 along the positive direction of the Z-axis.

[0057] Please refer to Figures 7 to 9 together. Figure 7 It is Figure 2 the A-A cross-sectional view in Figure 8 It is Figure 7 the enlarged view of the partial view H3 in Figure 9 It is Figure 7 the enlarged view of the partial view H4 in

[0058] In an assembly scenario, the signal transmission member 300 is snapped into the corresponding first guiding groove 215 and second guiding groove 217, and inserted into the accommodating cavity 201 along the reverse direction of the Z-axis. During the insertion of the signal transmission member 300, the first buckle 303 abuts against the first groove bottom 227 of the first guiding groove 215 along the reverse direction of the Y-axis, causing the first side portion 207 to elastically deform outward. Similarly, the second buckle 305 abuts against the second groove bottom 229 of the second guiding groove 217 along the positive direction of the Y-axis, causing the second side portion 209 to elastically deform outward. When the first buckle 303 moves to the first engaging groove 219, the first side portion 207 resets, enabling the first buckle 303 to be inserted into the first engaging groove 219. When the second buckle 305 moves to the second engaging groove 221, the second side portion 209 resets, enabling the second buckle 305 to be inserted into the second engaging groove 221. In this way, the signal transmission member 300 is snap-connected to the housing 200.

[0059] In the embodiment of the present application, the housing 200 elastically deforms outward relative to the signal transmission member 300, so that the signal transmission member 300 is inserted into the accommodating cavity 201 and a snap-connection structure is formed. Similarly, under the action of an external force, the housing 200 can also elastically deform outward relative to the signal transmission member 300, resulting in the release of the snap-connection structure, and further separating the housing 200 from the signal transmission member 300. To prevent the housing 200 from elastically deforming outward relative to the signal transmission member 300, the high-speed connector 100 further includes a locking member 400. The locking member 400 is in limit cooperation with the housing 200 and the signal transmission member 300 respectively, so as to prevent the housing 200 from elastically deforming outward relative to the signal transmission member 300.

[0060] Please refer to Figures 10 to 13 。 Figure 10 is a three-dimensional exploded view of the high-speed connector 100 from the third perspective in the embodiment of the present application. Figure 11 is Figure 10 an enlarged view of the partial view H5 in Figure 12 is a three-dimensional structure diagram of the high-speed connector 100 from the third perspective in the embodiment of the present application. Figure 13 is Figure 12 an enlarged view of the partial view H6 in

[0061] In some embodiments, the housing 200 has a first limiting groove 203 located inside the accommodating cavity 201. The signal transmission member 300 has a second limiting groove 301 located inside the accommodating cavity 201. The locking member 400 is in limit cooperation with the housing 200 through the first limiting groove 203 and in limit cooperation with the signal transmission member 300 through the second limiting groove 301 to limit the housing 200 from elastically deforming outward relative to the signal transmission member 300 at the snap-connection joint.

[0062] Specifically, a plurality of first limiting grooves 203 are provided on the first side portion 207. The first limiting grooves 203 correspond to the signal transmission members 300 one by one.

[0063] Under the limiting action of the locking member 400, the first side portion 207 is fixedly connected to the signal transmission member 300, so that the first side portion 207 cannot elastically deform outward relative to the signal transmission member 300, and further the fastening connection structure between the signal transmission member 300 and the first side portion 207 cannot be released.

[0064] Similarly, the signal transmission member 300 and the second side portion 209 can also be limited by another locking member 400, so that the second side portion 209 cannot elastically deform outward relative to the signal transmission member 300, and further the fastening connection structure between the signal transmission member 300 and the second side portion 209 cannot be released. Figures 2 to 7 In the illustrated embodiment, another locking member 400 is not provided on the second side portion 209.

[0065] In the above embodiment, the locking member 400 is respectively in limiting cooperation with the housing 200 and the signal transmission member 300 to prevent the fastening connection structure from being released, and the signal transmission member 300 is fastened to the housing 200 to prevent the two from separating. Among them, the limiting cooperation structures of the locking member 400 with the housing 200 and the signal transmission member 300 are both located in the accommodating cavity 201, making full use of the internal space of the housing 200 and reducing the occupied space of the high-speed connector 100.

[0066] Please refer to Figures 14 to 16 。 Figure 14 is the front view of the high-speed connector 100 in the embodiment of the present application. Figure 15 is Figure 14 the enlarged view of the partial view H7 in Figure 16 is the partial enlarged view of the front view of the high-speed connector 100 in the embodiment of the present application after omitting the locking member 400.

[0067] In some embodiments, the openings of the first limiting groove 203 and the second limiting groove 301 are oppositely arranged. The opening directions of the first limiting groove 203 and the second limiting groove 301 both intersect with the direction in which the housing 200 elastically deforms outward relative to the signal transmission member 300 at the fastening connection. Among them, the locking member 400 is respectively clamped in the first limiting groove 203 and the second limiting groove 301.

[0068] Specifically, the opening of the first limiting groove 203 faces the positive direction of the X axis, and the opening of the second limiting groove 301 faces the negative direction of the X axis. The direction in which the housing 200 elastically deforms outward relative to the signal transmission member 300 at the fastening connection is the negative direction of the Y axis.

[0069] In some embodiments, the housing 200 includes a housing body 233 and a resisting portion 235. The housing body 233 forms a receiving cavity 201. The resisting portion 235 is received in the receiving cavity 201, is disposed on the opposite side of the second limiting groove 301, is connected to the housing body 233, and extends inwardly and then extends toward the signal transmission member 300. Wherein, the housing body 233 and the resisting portion 235 enclose to form a first limiting groove 203. At least a part of the locking member 400 is clamped between the housing body 233 and the resisting portion 235.

[0070] The locking member 400 is in concave-convex fit with the housing 200 along the X-axis through the first limiting groove 203, so that the two are relatively fixed along the Y-axis. The locking member 400 is in concave-convex fit with the signal transmission member 300 along the X-axis through the second limiting groove 301, so that the two are relatively fixed along the Y-axis. Thus, the housing 200 and the signal transmission member 300 are relatively fixed along the Y-axis. The locking member 400 can limit the reverse movement of the housing 200 relative to the signal transmission member 300 along the Y-axis at the fastening connection.

[0071] In some embodiments, both the first limiting groove 203 and the second limiting groove 301 extend along the direction in which the signal transmission member 300 is inserted into the receiving cavity 201, and the starting ends of the extensions are both open. Wherein, at least a part of the locking member 400 is respectively inserted into the first limiting groove 203 and the second limiting groove 301 from the starting ends thereof.

[0072] Specifically, the starting ends of both the first limiting groove 203 and the second limiting groove 301 are the ends in the Y-axis direction. The opening directions of the starting ends of the first limiting groove 203 and the second limiting groove 301 are the positive direction of the Y-axis. In an assembly scenario, after the signal transmission member 300 is assembled to the housing, the locking member 400 is inserted into the first limiting groove 203 and the second limiting groove 301 along the reverse direction of the Y-axis.

[0073] In some embodiments, the locking member 400 presses against the bottom of the first limiting groove 203 along the opening direction of the second limiting groove 301, and presses against the bottom of the second limiting groove 301 along the opening direction of the first limiting groove 203.

[0074] Specifically, the third bottom 231 and the fourth bottom 315 are relatively disposed along the X-axis. The locking member 400 is in interference fit with the third bottom 231 and the fourth bottom 315 respectively, so that the locking member 400 is respectively fixed to the housing 200 and the signal transmission member 300. At the same time, the holding force of the housing 200 and the signal transmission member 300 in the Z-axis can also be increased.

[0075] In some embodiments, the housing 200 further has a third limiting portion 319 located in the receiving cavity 201. Wherein, the locking member 400 presses the signal transmission member 300 against the third limiting portion 319 along the opening direction of the first limiting groove 203.

[0076] Specifically, the locking member 400 presses against the outer shell 200 along the reverse direction of X, and presses the signal transmission member 300 against the outer shell 200 along the positive direction of the X-axis. The third limiting portion 319 can limit the installation position of the signal transmission member 300 on the X-axis.

[0077] Please refer to Figure 17 and Figure 18 . Figure 17 is Figure 14 a partial enlarged view of the B-B cross-sectional view in Figure 18 is a partial structural schematic diagram of the locking member 400 in the embodiment of the present application.

[0078] The locking member 400 includes a main body portion 401, a first convex portion 403, and a second convex portion 405. The main body portion 401 is respectively clamped in the first limiting groove 203 and the second limiting groove 301. The first convex portion 403 protrudes from the main body portion 401 along the opening direction of the second limiting groove 301, and presses against and is embedded in the bottom of the first limiting groove 203. The second convex portion 405 protrudes from the main body portion 401 along the opening direction of the first limiting groove 203, and presses against and is embedded in the bottom of the second limiting groove 301.

[0079] In some embodiments, the number of the first convex portions 403 is multiple, and the protruding heights of the multiple first convex portions 403 gradually decrease along the direction in which the locking member 400 is inserted into the first limiting groove 203. The number of the second convex portions 405 is multiple, and the protruding heights of the multiple second convex portions 405 gradually decrease along the direction in which the locking member 400 is inserted into the second limiting groove 301.

[0080] Specifically, the number of the first convex portions 403 is two, and the two first convex portions 403 are arranged at intervals along the Z-axis. During the process of the locking member 400 being inserted into the first limiting groove 203 along the reverse direction of the Z-axis, the first convex portion 403 with a height of H1 first pierces into the third bottom 231 of the first limiting groove 203, and then the first convex portion 403 with a height of H2 pierces into the third bottom 231 of the first limiting groove 203. Wherein, H2 is greater than H1. In this way, it is more convenient for the locking member 400 to be inserted into the first limiting groove 203. The first convex portion 403 is embedded in the outer shell 200, so that a holding force in the Z-axis is formed between the locking member 400 and the outer shell 200. In some embodiments, the outer shell 200 is made of plastic material, and the locking member 400 is made of stainless steel material. The setting manner of the second convex portion 405 can refer to the setting manner of the first convex portion 403, and will not be elaborated here.

[0081] The main body 401 is in limiting cooperation with the outer shell 200 through the first limiting groove 203 and in limiting cooperation with the signal transmission member 300 through the second limiting groove 301. The first convex portion 403 is embedded in the outer shell 200, and the second convex portion 405 is embedded in the signal transmission member 300, so that a holding force along the Z-axis is generated between the locking member 400 and the outer shell 200 and the signal transmission member 300 respectively.

[0082] In some embodiments, the locking member 400 is in the shape of a flat plate. When the locking member 400 is in the assembled state, it is perpendicular to the Y-axis. Specifically, the locking member 400 can be formed by sheet metal stamping. Thus, the manufacturing cost is low, and at the same time, the space occupied by the locking member 400 is small.

[0083] Please refer to Figure 10 and Figure 19 。 Figure 19 is the front view of the locking member 400 in the implementation of this application.

[0084] In some embodiments, the number of the signal transmission members 300 is multiple, and the multiple signal transmission members 300 are arranged at intervals in sequence. The number of the first limiting grooves 203 is multiple, and the first limiting grooves 203 correspond to the signal transmission members 300 one by one. The locking member 400 includes a first portion 407 and multiple second portions 409, and the multiple second portions 409 are arranged on the first portion 407 at intervals in sequence, and the second portions 409 correspond to the signal transmission members 300 one by one. Among them, the second portion 409 is respectively clamped in the corresponding first limiting groove 203 and the second limiting groove 301 of the corresponding signal transmission member 300.

[0085] In an assembly scenario, multiple signal transmission members 300 are assembled to the outer shell 200, and then the locking member 400 is assembled to the outer shell 200. One locking member 400 can fixedly connect multiple signal transmission members 300 to the outer shell 200, thereby reducing the assembly process.

[0086] To improve the connection stability between the signal transmission member 300 and the outer shell 200 and reduce the probability of the separation of the signal transmission member 300 from the outer shell 200, the following improvements are also made.

[0087] Please refer to Figure 20 and Figure 21 。 Figure 20 is a partial three-dimensional structural schematic diagram of the outer shell 200 in the embodiment of this application. Figure 21 is a partial three-dimensional structural schematic diagram of the signal transmission member 300 in the embodiment of this application.

[0088] At the second side portion 209, the signal transmission member 300 and the outer shell 200 also have a limiting structure to limit the relative position of the signal transmission member 300 and the second side portion 209 in the Y-axis direction.

[0089] Specifically, the second side portion 209 is further provided with a third limiting groove 239. The third limiting groove 239 extends along the reverse direction of the Z axis, and the starting end of the third limiting groove 239 is open along the positive direction of the Z axis. The signal transmission member 300 further includes a limiting protrusion 317. During the process that the signal transmission member 300 is inserted into the accommodation cavity 201 along the reverse direction of the Z axis under the guidance of the second guiding groove 217, the limiting protrusion 317 is inserted into the third limiting groove 239. The signal transmission member 300 is in limiting cooperation with the outer shell 200 through the limiting protrusion 317, so that their positions in the Y axis are relatively fixed.

[0090] In summary, to solve the problems such as fixed reliability caused by space occupation due to improving shielding and return of high-speed connectors, the above embodiments add a connection and fixation structure. In this way, the signal transmission member and the outer shell are connected, so that the signal transmission member and the outer shell form an integral whole, and the structure is stable and reliable. It can solve the problems that as the rate of the connector is getting higher and higher, more structures and components need to be added in a limited space to improve shielding and return, resulting in limited space for the fixing method of the connector and reliability problems such as shell detachment.

[0091] The introduction provided in the above steps is only used to help understand the method, structure and core idea of the present application. For those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
