[0058] In the embodiments illustrated in the present invention, the x-axis direction is the first direction, the y-axis direction is the second direction, and the z-axis direction is the third direction. The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0059] The present invention discloses a protective cover assembly 100, which includes a housing 1.

[0060] The housing 1 includes a mating end face 10 and a first mating space 2. The first mating space 2 extends through the mating end face 10 along the x-axis. The socket connector 200 is housed at the rear end (positive x-axis direction) of the first mating space 2. A corresponding plug connector assembly 300 can extend at least partially into the first mating space 2 and mate with the socket connector 200.

[0061] In the illustrated embodiment, see Figure 3 and Figure 4 The housing 1 further includes a first top wall 11, a first bottom wall 12, a first side wall 13, and a second side wall 14. The first docking space 2 is formed by at least the first top wall 11, the second bottom wall 12, the first side wall 13, and the second side wall 14.

[0062] The first top wall 11 has a first opening 111. The first opening 111 extends along the x-axis direction, with one end extending toward and through the mating end face 10; the other end extends toward the rear end (the end pointing in the positive x-axis direction) of the housing 1 and is a distance away from the rear end face of the housing 1.

[0063] The first opening 111 opens the first docking space 2, so that the actual docking space is no longer limited to the first docking space 2.

[0064] The aforementioned actual mating space refers to the space required for the plug connector assembly 300 to move within the protective cover assembly 100 of the socket connector assembly 400 when the plug connector assembly 300 mates with the socket connector assembly 400. In related technologies, the actual mating space is a part of the first mating space 2.

[0065] See Figure 5 The first top wall 11 has a first wall portion 112. There are two first wall portions 112. The two first wall portions 112 are respectively located on the left and right sides (z-axis pointing side) of the first opening 111. The sides of the two first wall portions 112 away from the first opening 111 are respectively fixedly connected to the first side wall 13 and the second side wall 14.

[0066] The first top wall 11 also has a first top wall body portion 110. The left and right sides of the first top wall body portion 110 are fixedly connected to the first side wall 13 and the second side wall 14, respectively. The first wall portion 112 extends along the x-axis direction, with one end extending to the mating end face 10 and the other end extending to the first top wall body portion 110.

[0067] See Figure 6 and Figure 7The first wall portion 112 has a plurality of first protrusions 1121. The plurality of first protrusions 1121 are spaced apart along the x-axis. The first protrusions 1121 extend toward the first docking space 2 and extend along the x-axis.

[0068] The first protrusion 1121 has a protrusion body portion 11210 and end portions 11211. There are two end portions 11211, located at the front and rear ends of the protrusion body portion 11210, respectively.

[0069] In the illustrated embodiment, the protruding body portion 11210 is a semi-cylinder with an approximately semi-circular cross-section, and the axis of the semi-cylinder is parallel to the x-axis. The end portion 11211 is approximately a quarter sphere. The end portion 11211 smoothly connects to the protruding body portion 11210, that is, the diameter of the semi-cylinder is substantially equal to the diameter of the quarter sphere.

[0070] In other embodiments of the present invention, the protruding body portion 11210 may also be a prism structure with a rectangular cross-section, and the end portion 11211 may be a quarter-cylinder with a sector-shaped cross-section, wherein the axis of the aforementioned quarter-cylinder is parallel to the z-axis direction. The end portion 11211 and the protruding body portion 11210 transition smoothly, that is, the radius of the quarter-cylinder constituting the end portion 11211 is equal to the height of the protruding body portion 11210 protruding into the first docking space 2 along the y-axis.

[0071] In other embodiments of the present invention, the protruding body portion 11210 and the end portion 11211 may also have other shapes. However, at least the end portion 11211 near the mating end face 10 has a guide surface, and the guide surface extends smoothly from the lower surface of the first wall portion 112 along the positive x-axis and the negative y-axis to the bottom surface of the protruding body portion 11210 (the negative y-axis pointing surface).

[0072] In other embodiments of the present invention, only one first protrusion 1121 may be provided. When only one first protrusion 1121 is provided, the extension distance of the first protrusion 1121 in the x-axis direction can be appropriately increased.

[0073] See Figure 5 The first top wall 11 also has two second wall portions 113, which are respectively fixed to the upper wall surfaces of the two first wall portions 112. It can be understood that fixing the second wall portions 113 to the upper wall surfaces of the first wall portions 112 is equivalent to increasing the thickness of the first wall portions 112, which can increase the strength of the first wall portions 112, thereby making the first wall portions 112 less prone to deformation when downward pressure is applied to the plug connector assembly 300.

[0074] The second wall portion 113 extends along the x-axis, with one end extending rearward until it approaches the first top wall body portion 110, and the other end extending forward until it approaches the enclosure 3 mentioned below.

[0075] In other embodiments of the invention, the other end of the second wall portion 113 may also extend to the mating end face 10.

[0076] It should be understood that, when viewed along the z-axis, the length of the second wall portion 113 is substantially the same as the length of the first wall portion 112, and the second wall portion 113 substantially overlaps the upper wall surface of the first wall portion 112, so as to cover as little space as possible above the first opening 111.

[0077] See Figure 3 and Figure 4 The first bottom wall 12 has a first bottom wall body portion 120, a first extension edge 121, and a second extension edge 122. In the illustrated embodiment, a portion of the left side (the side pointing in the positive z-axis direction) of the first bottom wall body portion 120 extends toward the first top wall 11 to form the first extension edge 121, and a portion of the right side of the first bottom wall body portion 120 extends toward the first top wall 11 to form the second extension edge 122.

[0078] The first extension 121 and the second extension 122 are respectively fastened to the first sidewall 13 and the second sidewall 14 by a snap-fit ​​structure.

[0079] The first bottom wall 12 has a first through hole 123. The first through hole 123 passes through the first bottom wall body portion 120 along the y-axis direction.

[0080] The first bottom wall 12 also has a protruding wall 124. Two protruding walls 124 are provided, and the two protruding walls 124 are respectively fixedly connected to the first bottom wall body portion 120 surrounding the first through hole 123 and located on the left and right sides of the first through hole 123. The protruding walls 124 extend from the first bottom wall 12 in a direction away from the first docking space 2. In the embodiment shown in the figures, the protruding walls 124 are formed by extending downward (negative y-axis direction) from the side of the first bottom wall body portion 120 surrounding the first through hole 123 and located on the left and right sides of the first through hole 123.

[0081] In other embodiments of the present invention, the protruding wall 124 may also be provided on the front and rear sides (x-axis pointing side) of the first through hole 123.

[0082] See Figure 9 and Figure 10Two locking protrusions 1241 are provided at intervals along the x-axis on the protruding wall 124.

[0083] See Figure 8 The first bottom wall 12 also includes a second opening 125. The second opening 125 penetrates the first bottom wall 12 along the y-axis, and one end of the second opening 125 extends to and penetrates the mating end face 10, while the other end of the second opening 125 extends backward along the x-axis for a certain distance.

[0084] When viewed along the x-axis, the second opening 125 is a certain distance away from the first through hole 123.

[0085] In the embodiment shown in the attached figure, when viewed along the z-axis, the second opening 125 is located in the middle of the first bottom wall 12.

[0086] The first bottom wall 12 also includes a first spring tab 126. The first spring tab 126 is located in the second opening 125. In the embodiment shown in the figures, the first spring tab 126 is formed by extending the wall surrounding the second opening 125 away from the mating end face 10 into the first mating space 2.

[0087] The first spring piece 126 has at least a first spring segment 1261 and a second spring segment 1262. The first spring segment 1261 has a guiding function, and when the mating plug connector assembly 300 extends into the first mating space 2, the first spring segment 1261 will guide the plug connector to be smoothly raised a certain distance.

[0088] The first elastic segment 1261 extends gradually upward and backward from the lower side of the first bottom wall 12 into the first docking space 2. The second elastic segment 1262 extends downward and backward from inside the first docking space 2 until it is fixedly connected to the first bottom wall body 120.

[0089] Combination Figures 1 to 4 The housing 1 further includes a rear wall 15. The rear wall 15 is fixedly connected to the first top wall 11, the first side wall 13, and the second side wall 14, respectively. In the illustrated embodiment, the first top wall 11, the first side wall 13, the second side wall 14, and the rear wall 15 are integrally formed from a single sheet of material.

[0090] See Figure 3 , Figure 4 as well as Figures 11 to 16 The protective cover assembly 100 further includes a sealing cover 3, which is fixed to the upper side of the housing 1. The sealing cover 3 includes a first end face 34, a second end face 35, a second docking space 37, a second top wall 31, a third side wall 32, and a fourth side wall 33.

[0091] The second docking space 37 extends through the first end face 34 along the x-axis direction, and the second top wall 31, the third side wall 32, and the fourth side wall 33 surround the outside of the second docking space 37.

[0092] The first end face 34 is located at one end of the enclosure 31, and the first end face 34 and the mating end face 10 are located in the same plane; the other end of the enclosure 31 extends a distance along the x-axis to form the second end face 35 of the enclosure 3.

[0093] In the embodiment shown in the attached figures, the second end face 35 is inclined relative to the first top wall 11. The maximum length of the enclosure 3 in the x-axis direction is less than the length of the first opening 111 in the same direction.

[0094] In the embodiment shown in the attached drawings, the second top wall 31 is parallel to the first top wall 11 and the first bottom wall 12. The first side wall 13, the second side wall 14, the third side wall 32, and the fourth side wall 33 are parallel. The aforementioned "parallel" means that the main body parts of the relevant components are parallel.

[0095] The left and right sides (z-axis pointing to the side) of the second top wall 31 are fixedly connected to the upper end (y-axis pointing to the positive end) of the third side wall 32 and the upper end of the fourth side wall 33, respectively; the lower ends of the third side wall 32 and the fourth side wall 33 are fixedly connected to the upper ends of the first side wall 13 and the second side wall 14, respectively.

[0096] In the embodiment shown in the attached figure, the second top wall 31, the third side wall 32, and the fourth side wall 33 are integrally formed from a single sheet of material.

[0097] The enclosure 3 is mounted on the upper side of the housing 1 and closes the first opening 111. The second top wall 31, the third side wall 32, the first side wall 13, the first bottom wall 12, the second side wall 14, and the fourth side wall 33 form a closed ring. It is understood that the entire housing 1 and the enclosure 3 are made of electromagnetic shielding material. The aforementioned closed ring provides better electromagnetic shielding for the plug connector assembly 300 located within the closed ring.

[0098] In the embodiment shown in the attached figure, the enclosure 3 further includes foot walls 36. The foot walls 36 are arranged parallel to the second top wall 31 at a distance. Two foot walls 36 are provided, respectively fixedly connected to the lower ends of the third side wall 32 and the fourth side wall 33.

[0099] In the embodiment shown in the attached figures, one foot wall 36 extends a distance from the lower end of the third side wall 32 toward the fourth side wall 33. The other foot wall 36 extends a distance from the lower end of the fourth side wall 33 toward the third side wall 32.

[0100] The two foot walls 36 are respectively fixed to the upper surfaces of the two first wall portions 112, and the sealing cover 3 is fixed to the first top wall 11.

[0101] Optional, combined Figure 3 and Figure 12 Along the z-axis, the first wall portion 112 and the foot wall 36 have the same length, and along the z-axis, the first wall portion 112 and the foot wall 36 are aligned and fixedly connected.

[0102] In another embodiment of the invention, the enclosure 3 may also extend to completely cover the first opening 111 in the x-axis direction.

[0103] In the embodiments shown in the attached figures, see Figures 11 to 16 The rear end of the second top wall 31 extends backward, upward, and forward, forming an open groove 311 with a cylindrical cavity. The axis of the aforementioned cylindrical cavity is parallel to the z-axis direction.

[0104] The second top wall 31 also has two fins 312 spaced apart along the z-axis. Each fin 312 has a third segment 3123, a first segment 3121, and a second segment 3122 connected sequentially along the x-axis. One end of the third segment 3123 is fixedly connected to the main body of the second top wall 31, the other end of the third segment 3123 is fixedly connected to one end of the first segment 3121, the other end of the first segment 3121 is fixedly connected to one end of the second segment 3122, and the other end of the second segment 3122 is suspended. The third segment 3123 extends in the plane containing the main body of the second top wall 31, the first segment 3121 extends away from the first docking space 2 along the positive x-axis and positive y-axis, and the second segment 3122 extends towards the first docking space 2 along the positive x-axis and negative y-axis. The second segment 3122 corresponds to the opening 3111 of the opening groove 311, and partially blocks the opening of the opening groove 311. There is a certain gap α between the second segment 3122 and the groove wall at the opening of the opening groove 311.

[0105] See Figures 11 to 15 The protective cover assembly 100 further includes a sheet-like member 4. The sheet-like member 4 covers the rear end of the enclosure 3. In the embodiment shown in the figures, one end of the sheet-like member 4 is rotatably connected to the rear end of the second top wall 31.

[0106] Specifically, the sheet-like component 4 has a pivot 41, a body portion 40, side wings 42, and a tail wing 43. The upper end of the body portion 40 is fixed to the pivot 41. The pivot 41 can be inserted into the cavity of the opening slot 311 from the gap α between the wing 312 and the slot wall of the opening slot 311, and the second segment 3122 of the wing 312 will prevent the pivot 41 from moving out of the cavity of the opening slot 311 along the negative x-axis.

[0107] It should be understood that, in order to enable the sheet-like member 4 to rotate relative to the opening groove 311 without interfering with the groove wall of the opening groove 311, the sheet-like member body 40 is provided with a clearance opening 401 at one end near the rotating shaft 41. The left and right ends of the upper side of the sheet-like member body 40 are fixedly connected to the rotating shaft 41.

[0108] The sheet-like component 4 also includes two side wings 42, which are located on the left and right sides (z-axis pointing side) of the sheet-like component body 40, respectively. The side wings 42 include a covering portion 421 and a guide portion 422. When the sheet-like component 4 is covered by the rear end of the enclosure 3, the covering portion 421 at least partially covers the outside of the third side wall 32 or the fourth side wall 33.

[0109] In the embodiment of the accompanying drawings, the left and right sides (z-axis pointing sides) of the sheet-like body portion 40 extend a distance toward the enclosure 3 in a direction perpendicular to the sheet-like body portion 40 to form the covering portion 421. The side of the covering portion 421 away from the sheet-like body portion 40 curves upward in a direction perpendicular to the third sidewall 32 or the fourth sidewall 33 away from the enclosure 3 to form the guide portion 422.

[0110] The rear end face of the sheet-like body portion 40 (that is, the end away from the pivot 41) extends in the plane of the sheet-like body portion 40 in a direction away from the sheet-like body portion 40, then rotates 180° and continues to extend a distance in a direction parallel to the sheet-like body portion 40 to form the tail fin 43.

[0111] In the illustrated embodiment, the tail fin 43 comprises three parts: a first part 431, a second part 432, and a third part 433.

[0112] Wherein, the first part 431 is a flat plate extending in the plane of the sheet-like body part 40, the second part 432 is an arc-shaped plate with a semi-cylindrical sidewall, and the third part 433 is a flat plate extending in a plane parallel to the sheet-like body part 40. The second part 432 connects the first part 431 and the third part 433.

[0113] In another embodiment of the present invention, the tail fin 43 is an arc-shaped surface that curves upward and backward from the sheet-like body portion 40.

[0114] When the sheet-like part 4 covers the rear end of the enclosure 3, the tail wing 43 extends into the first docking space 2.

[0115] Optionally, the sheet-like body portion 40 is provided with a plurality of through slots 402.

[0116] The protective cover assembly 100 further includes an elastic element. The elastic element is disposed between the sheet-like member 4 and the enclosure 3. The elastic element provides a force to the sheet-like member 4 against the second end face 35 of the enclosure 3.

[0117] In the illustrated embodiment, the elastic element is a spring 5, and two springs 5 ​​are provided in the protective cover assembly 100. Each spring 5 is entirely located inside the enclosure 3, and the spring 5 extends along the side wall of the enclosure 3 adjacent to it, maximizing the space between the third side wall 32 and the fourth side wall 33. See also Figure 11 and Figure 12 One of the springs 5 ​​extends along the third sidewall 32, with one end hooked to the third sidewall 32 and the other end hooked to the sheet-like body portion 40; another spring 5 extends along the fourth sidewall 33, with one end hooked to the fourth sidewall 33 and the other end hooked to the sheet-like body portion 40.

[0118] It should be understood that the elastic element can also be other elastic structures such as torsion springs.

[0119] In the preceding embodiments, the sheet-like member 4 is rotatably connected to the enclosure 3. In other embodiments of the present invention, the sheet-like member 4 may also be fixedly connected to the enclosure 3. In this case, the sheet-like member 4, relying on its own strong elasticity, can be lifted a certain distance in the y-axis direction, thereby enabling the protective cover assembly 100 to be compatible with both conventional plug connector assembly 300' and heightened plug connector assembly 300'.

[0120] The protective cover assembly 100 also includes a heat sink 6. (See also...) Figure 4 The heat sink 6 is fixed to the first bottom wall 12, and extends into the first docking space 2 through the first through hole 123.

[0121] The heat sink 6 includes a heat sink substrate 61 and a plurality of heat sinks 62. The plurality of heat sinks 62 are arrayed and fixed to the lower surface of the heat sink substrate 61.

[0122] The heat sink 6 also has a protrusion 63. The protrusion 63 extends upward from the upper surface of the heat sink substrate 61. The protrusion 63 extends along the x-axis, with one end extending to a distance from the front end of the heat sink substrate 61 and the other end extending to a distance from the rear end of the heat sink substrate 61.

[0123] The front end face of the protrusion 63 is inclined relative to the upper surface of the heat dissipation substrate 61.

[0124] The protective cover assembly 100 also includes a locking member 7, which has two first connecting strips 71 spaced apart and arranged side by side along the x-axis, and two second connecting strips 72 spaced apart and arranged side by side along the z-axis. The two second connecting strips 72 are respectively fixed to the two ends of the two first connecting strips 71.

[0125] The second connecting strip 72 has two positioning holes 721. The two positioning holes 721 are spaced apart along the x-axis.

[0126] The two first connecting strips 71 can pass through the heat sinks 62 of the array, and the positioning hole 721 locks onto the locking protrusion 1241, thereby fixing the heat sink 6 to the first bottom wall 12.

[0127] After the heat sink 6 is fixed on the first bottom wall 12, the upper surface of the heat sink substrate 61 abuts against the lower surface of the first bottom wall 12, and the protrusion 63 protrudes into the first docking space 2.

[0128] The protective cover assembly 100 also includes a grounding spring 8, which is fixedly surrounded on the outer side of a closed ring formed by the second top wall 31, the fourth side wall 33, the second side wall 14, the first bottom wall 12, the second side wall 13 and the third side wall 32.

[0129] The present invention also discloses a socket connector assembly 400. For example... Figure 1 , Figure 17 as well as Figure 18 As shown, it includes the protective cover assembly 100 described above, and further includes a socket connector 200. The socket connector 200 is housed at the rear end of the first mating space 2.

[0130] The present invention also discloses a connector assembly 500, such as Figure 17 As shown, it includes a plug connector assembly 300 and a socket connector assembly 400 disclosed above.

[0131] The plug connector assembly 300 includes a housing 9 and a plug connector (not identified) housed within the housing 9. The housing 9 includes a first housing portion 91 and a second housing portion 92. In the invention, the first housing portion 91 is also referred to as an insertion portion.

[0132] As can be seen from the foregoing, the socket connector assembly 400 of the present invention is compatible with the conventional plug connector assembly 300' and the heightened plug connector assembly 300'.

[0133] In this invention, "conventional" in the conventional plug connector assembly 300' refers to a shorter type or one without a heat sink.

[0134] In this invention, the conventional plug connector assembly 300' is a plug connector assembly 300 that is shorter than the heightened plug connector assembly 300" (or, in other words, the heightened plug connector assembly 300" is a plug connector assembly that is taller than the conventional plug connector assembly 300' that matches the socket connector assembly 400). More specifically, in this invention, the conventional plug connector assembly 300' refers to a plug connector assembly 300 that is not fitted with the socket heat sink 93 mentioned below, compared to the heightened plug connector assembly 300".

[0135] See also Figures 17 to 19 b. When mating with a conventional plug connector assembly 300', the first housing portion 91 is inserted into the first mating space 2 in the protective cover assembly 100, and the plug connector located inside the housing 9 is electrically connected to the socket connector 200 located at the rear end of the first mating space 2.

[0136] The sheet-like member 4 covers and presses against the second end face 35 of the enclosure 3 under the tension of the spring 8, and the tail wing 43 of the sheet-like member 4 abuts against the upper surface of the insertion portion, giving the upper surface of the insertion portion a downward force. The upper surface of the insertion portion of the plug connector assembly 300' abuts against the first protrusion 1121.

[0137] The aforementioned tail fin 43 and the first protrusion 1121 both exert a downward force on the plug connector assembly 300', thereby causing the insertion part to abut tightly against the protrusion 63 of the heat sink 6 located on the lower side of the insertion part, thus improving the heat dissipation performance of the heat sink 6.

[0138] Reference Figure 20 Compared to the conventional plug connector assembly 300' described above, the heightened plug connector assembly 300" also includes a socket heat sink 93, which is fixed to the upper surface of the housing 9.

[0139] When the heightened plug connector assembly 300” mates with the socket connector assembly 400, the insertion part is inserted into the first mating space 2 in the protective cover assembly 100. At the same time, the socket heat sink 93 located on the upper surface of the housing 9 passes through the second mating space 37, lifts the sheet 4, and exposes it at least partially to the air above the first opening 111.

[0140] The tail fin 43 of the sheet member 4 is pressed against the upper surface of the insertion portion under the tension of the spring 8. The first protrusion 1121 abuts against the upper surface of the insertion portion of the plug connector assembly 300". Both the tail fin 43 and the first protrusion 1121 exert a downward force on the insertion portion, thereby causing the lower surface of the insertion portion to abut tightly against the protrusion 63, thus improving the heat dissipation effect of the heat sink 6.
