[0061] The terms used in the embodiments of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application. The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0062] With the development of big data, cloud computing and artificial intelligence (AI), the number of circuit boards in computing devices gradually increases.

[0064] Referring to Figure 1 and Figure 2 As shown in the drawings, the computing device 10 can be a desktop server, a blade server, a rack server, a high-density server, an entire cabinet server, etc. Of course, the computing device can also be other electronic devices that can realize blind insertion. The computing device 10 includes a housing 700, a first board card 100, a second board card 200 and a connector assembly 300, the first board card 100, the second board card 200 and the connector assembly 300 are all arranged in the housing 700, a socket 310 in the connector assembly 300 is connected with the first board card 100, and a plug 320 in the connector assembly 300 is connected with the second board card 200.

[0065] The first board card 100 can be one of a mainboard, a backboard, a network card, a fan board and other circuit boards, and the second board card 200 can be another one of the mainboard, the backboard, the network card, the fan board and other circuit boards. For example, the first board card 100 can be a mainboard, and the second board card 200 can be a fan board. For another example, the first board card 100 can be a mainboard, and the second board card 200 can be a backboard.

[0066] The first board card 100 and the second board card 200 can be electrically connected through the connector assembly 300. The connector assembly 300 includes the socket 310 and the plug 320. In the embodiments shown in Figure 1 and Figure 2 In the embodiments shown in the drawings, the socket 310 is arranged on the first board card 100 and is electrically connected with the first board card 100. The computing device 10 further includes a mounting plate 400, the plug 320 and the second board card 200 are both mounted on the mounting plate 400, and the plug 320 can be electrically connected with the second board card 200 through a cable 500. In other embodiments, the socket 310 can also be connected with the first board card 100 through a mounting plate, or the plug 320 can also be directly arranged on the second board card 200.

[0067] Figure 3 This is a schematic diagram of the assembly process of a computing device provided in an embodiment of the present application. Figure 3 Only a portion of the first board 100 and the second board 200 is shown.

[0068] See also Figure 3 As shown, when assembling the computing device 10, the socket 310 can be first set on the first board 100 and electrically connected to the first board 100, the plug 320 and the second board 200 can be set on the mounting plate 400, and the plug 320 and the second board 200 can be electrically connected through the cable 500; then the plug 320 can be plugged into the socket 310 to electrically connect the first board 100 and the second board 200.

[0069] The socket 310 has multiple first terminals, and the plug 320 has multiple second terminals. When plugging the plug 320 into the socket 310, the first and second terminals need to be aligned and plugged in one by one. The computing device 10 has many components. When plugging the plug 320 into the socket 310, it is difficult to see whether the plug 320 and the socket 310 are aligned, or whether the first terminals in the socket 310 and the second terminals in the plug 320 are aligned one by one, due to obstruction by the first board 100, the second board 200, or other components. This type of plugging is called blind plugging. Therefore, the plug 320 and the mounting plate 400 can be connected in a floating manner. The plug 320 can float relative to the mounting plate 400 within a floating range, so that even if the positions of the plug 320 and the socket 310 are slightly offset, the plug 320 can still be plugged into the socket 310. However, when the position of the plug 320 is slightly offset relative to the socket 310 , blind insertion may easily damage the socket 310 or the plug 320 , causing the socket 310 to have an excessively poor tolerance for the positional offset of the plug 320 .

[0070] Based on this, an embodiment of the present application provides a computing device and a connector assembly. By providing a two-stage guide structure in the connector assembly, the tolerance of the socket 310 to the position deviation of the plug 320 can be improved.

[0073] Specifically, please continue to refer to Figure 4 to Figure 6 As shown in the figure, the socket shell 312 is used to accommodate the plurality of first terminals 311, and the socket shell 312 can have a cylindrical shape, a cuboid shape or other shapes. In Figure 4 to Figure 6 In the embodiment shown in the figure, the socket shell 312 is a cuboid. The first direction X, the second direction Y and the third direction Z of the cuboid are shown in the figure.

[0074] Please continue to refer to Figure 5 and Figure 6 As shown in the figure, the socket shell 312 includes a bottom wall 3122 and a side wall 3123 arranged on the side of the bottom wall 3122, and the socket shell 312 has an opening at the end opposite to the bottom wall 3122 along the third direction Z, the opening is oriented towards the plug 320, and the direction of the opening is the orientation of the plug end face of the socket 310. Among them, the third direction Z is the direction in which the first terminal 311 in the socket 310 and the second terminal 321 in the plug 320 plug in. The partition 313 can be a partition plate in the socket shell 312, and the partition 313 can extend along the first direction X, can extend along the second direction Y, or can extend along a direction inclined with respect to the first direction X and the second direction Y. In Figure 5 and Figure 6In the embodiment shown in FIG. 3, one partition 313 extending along the first direction X and three partitions 313 extending along the second direction Y are shown, the partition 313 extending along the first direction X and the partition 313 extending along the second direction Y intersecting to divide the space in the socket housing 312 into a plurality of accommodation spaces 314. The side wall 3123 has a dimension along the third direction Z slightly larger than the dimension of the partition 313 along the third direction Z.

[0075] The first terminal 311 is arranged in each of the accommodation spaces 314. In the embodiment shown in FIG. 3, the first terminal 311 partially extends from the bottom wall 3122 to be inserted into the jack in the first board 100, thereby fixing the socket 310 on the first board 100 and electrically connecting the socket 310 with the first board 100.

[0076] Please continue to refer to Figure 6a In the embodiment shown in FIG. 3, the side opposite to the bottom wall 3122 of the socket housing 312 has a first end face 3124, the partition 313 has a second end face 3132, the first end face 3124 and the second end face 3132 have the same orientation as the opening, the first end face 3124 is away from the first terminal 311 by a first distance L1 toward the side of the opening, the second end face 3132 is away from the first terminal 311 by a second distance L2 toward the side of the opening, the first distance L1 is greater than the second distance L2, that is, the second end face 3121 of the partition 313 is recessed relative to the first end face 3124 of the socket housing 312 along the third direction Z.

[0077] Please continue to refer to Figure 5 、 Figure 7 and Figure 8 In the embodiment shown in FIG. 3, the plug 320 includes a plug body 323 for supporting the protective sleeve 322, a plurality of protective sleeves 322 are arranged on the plug body 323 and extend from the plug body 323 along the third direction Z, the second terminal 321 is arranged in the protective sleeve 322, and the protective sleeve 322 is used for protecting the second terminal 321. Therefore, the dimension of the protective sleeve 322 along the third direction Z can be slightly larger than that of the second terminal 321. The protective sleeve 322 is arranged in one-to-one correspondence with the accommodation space 314, so that the first terminal 311 and the second terminal 321 are inserted into each other in one-to-one correspondence. In Figure 4 to Figure 8 In the embodiment shown in FIG. 3, the first terminal 311 is a pin, and the second terminal 321 is a metal sleeve, the pin is inserted into the metal sleeve to electrically connect the first terminal 311 with the second terminal 321.

[0078] The second terminal 321 forms an arrangement region S on the plug body 323, and the arrangement region S can be a rectangular array, a circular array or an array of other shapes. In Figure 5 、 Figure 7 and Figure 8 In the embodiment shown in FIG. 3, the arrangement region S is a rectangular array of four rows arranged along the first direction X and two rows arranged along the second direction Y.

[0079] Please continue to see Figure 6 and Figure 6a As shown in , the side wall 3123 of the socket housing 312 has a first guide surface 3121 on the side close to the first end surface 2134, which can be a first inclined surface on the side wall 3123, and the first guide surfaces 3123 on the four side walls 3123 form a horn structure at the opening of the socket housing 312. The inclination angle α of the first guide surface 3121 relative to the side wall 2123 can be in the range of 10°-60°.

[0080] Figure 6 The first guide surface 3121 can be two, and the two first guide surfaces 3121 can be oppositely arranged along the first direction X, or oppositely arranged along the second direction Y. That is, the first guide surface 3121 can be arranged in pairs along the first direction X or the second direction Y, thereby guiding the plug-in process along the first direction X or the second direction Y. In , two first guide surfaces 3121 oppositely arranged along the first direction X and two first guide surfaces 3121 oppositely arranged along the second direction Y are shown, thereby guiding the plug-in process along the first direction X and the second direction Y.

[0081] Figure 7 Please continue to see Figure 7 , when the plug 320 is plugged into the socket 310, the second guide surface 3221 can be arranged on the side of a part of the protective sleeves 322 facing the outside of the arrangement area S, or the second guide surface 3221 can be arranged on the side of all the protective sleeves 322 facing the outside of the arrangement area S. Figure 9 In Figure 1 , the protective sleeves 322 at both ends along the first direction X are provided with the second guide surface 3221. The inclination direction of the second guide surface 3221 is the same as that of the first guide surface 3121. Figure 9 to Figure 12a The plug-in process of the plug and the socket in the connector assembly provided by the embodiment of the present application is shown in , in which

[0082] the first terminal and the second terminal are omitted. Figure 9As shown, the plug 320 and the socket 310 are slightly staggered along the first direction X (or the second direction Y), and since the second end surface 3121 of the partition 313 is recessed along the third direction Z relative to the first end surface 3124 of the socket housing 312, the second guide surface 3221 in the protective sleeve 322 first contacts the first guide surface 3121 of the socket housing 312. While the plug 320 moves relative to the socket 310 along the third direction Z, the second guide surface 3221 slides relative to the first guide surface 3121, and the plug 320 moves along the first direction X while moving along the third direction Z, so that the plug 320 is aligned with the socket 310 along the third direction Z. In Figure 9 The movement track of the plug 320 is shown in dashed line in FIG. 13. The plug 320 and the socket 310 are plugged in the state of being aligned along the third direction Z. Thus, even if the plug 320 is staggered relative to the socket 310, the plug 320 and the socket 310 can be smoothly plugged in by the structure of the first guide surface 3121 forming a horn and by the cooperation of the second guide surface 3221 and the first guide surface 3121, and the tolerance capability of the socket 320 to the position offset of the plug 320 can be increased. It should be noted that the size by which the plug 320 and the socket 310 can be staggered along the first direction X (or the second direction Y) is related to the projection size of the first guide surface 3121 along the third direction Z, and the projection size of the first guide surface 3121 along the third direction Z is positively correlated with the inclination angle a of the first guide surface 3121 relative to the side wall 2123. The greater the inclination angle a of the first guide surface 3121 relative to the side wall 2123, the greater the projection size of the first guide surface 3121 along the third direction Z, and the greater the size by which the plug 320 and the socket 310 can be staggered along the first direction X (or the second direction Y).

[0083] Figure 10 The plugging process of the plug and the socket in the connector assembly provided by the embodiments of the present application is shown Figure 2 .

[0084] Referring to Figure 10 As shown, the plug 320 is inclined relative to the socket 310, and thus, when plugging the plug 320 and the socket 310, the first guide surface 3121 on the side wall 3123 first contacts the second guide surface 3221 on the protective sleeve 322, so that the second guide surface 3221 slides relative to the first guide surface 3121 while the plug 320 moves relative to the socket 310 along the third direction Z, and the second guide surface 3221 gradually fits on the first guide surface 3121, the inclination angle of the plug 320 relative to the socket 310 gradually decreases, and the plug 320 is aligned with the socket 310 along the third direction Z. In Figure 10The movement track of the plug 320 is shown by a dashed line. The plug 320 and the socket 310 are plugged in a state of alignment along the third direction Z. Thus, even if the plug 320 is tilted relative to the socket 310, the structure of the horn formed by the first guide surface 3121 and the cooperation of the first guide surface 3121 and the second guide surface 3221 can make the plug 320 and the socket 310 smoothly plugged, and can increase the tolerance of the position deviation of the plug 320 to the socket 320.

[0085] Please continue to see FIG. 6 and Figure 6a As shown, the partition 313 has a third guide surface 3131 on one side close to the second end surface 3132. Please continue to see FIG. 6 and Figure 7 As shown, the side of the protective sleeve 322 facing the inside of the arrangement area S has a fourth guide surface 3222 matching the third guide surface 3131.

[0086] Figure 11 The plug and the socket of the connector assembly provided by the embodiment of the present application Figure 3 ; Figure 11a For Figure 11 the enlarged view of A in FIG. 6.

[0087] Please see Figure 11 and Figure 11a As shown, as the plug 320 continues to move along the third direction Z, the protective sleeve 322 gradually approaches the partition 313. One of the protective sleeves 322 has a slight deviation in position during processing (in Figure 11 and Figure 11aThe designed position of the shield 322 is shown by a dashed line, and the actual position of the shield 322 is offset from the designed position along the first direction X, so that the shield 322 is slightly misaligned with the position of the accommodating space 314 along the first direction X. A third guide surface 3131 can be provided on the partition 313, and the third guide surfaces 3131 on the four partitions 313 around each accommodating space 314 form a horn structure. A fourth guide surface 3222 is provided on the side of the shield 322 facing the partition 313, and the fourth guide surface 3222 is in contact with the third guide surface 3131. As the plug 320 is further moved along the third direction Z, the fourth guide surface 3222 slides relative to the third guide surface 3131, and the shield 322 moves along the first direction X while moving along the third direction Z, so that the shield 322 is aligned with the accommodating space 314 along the third direction Z. The shield 322 enters the accommodating space 314 in the state of being aligned with the accommodating space 314. Thus, even if part of the shield 322 is misaligned with the accommodating space 314, the shield 322 can smoothly enter the accommodating space 314 through the horn structure formed by the third guide surface 3131 and the cooperation of the fourth guide surface 3222 and the third guide surface 3131, and the tolerance capability of the socket 320 to the position offset of the shield 322 in the plug 320 can be increased, so as to facilitate the plug-in of the second terminal 321 in the shield 322 and the first terminal 311 in the accommodating space 314.

[0088] Figure 12 The plug-in process of the connector assembly provided by the embodiment of the present application Figure 4 ; Figure 12a For Figure 12 the enlarged view in b.

[0089] Referring to Figure 12 and Figure 12a , one of the shields 322 is slightly inclined in position during processing (in Figure 12The designed position of the shield 322 is shown by a dashed line, and the actual position of the shield 322 is inclined relative to the designed position. A third guide surface 3131 can be provided on the partition 313, and the third guide surfaces 3131 on the four partitions 313 around each accommodation space 314 form a horn structure. A fourth guide surface 3222 is provided on the side of the shield 322 facing the partition 313, and the fourth guide surface 3222 is in contact with the third guide surface 3131. As the plug 320 is further moved in the third direction Z, the fourth guide surface 3222 slides relative to the third guide surface 3131, and the fourth guide surface 3222 gradually fits on the third guide surface 3131. The inclination angle of the shield 322 relative to the accommodation space 314 gradually decreases, until the shield 322 is aligned with the accommodation space 314 in the third direction Z. The shield 322 enters the accommodation space 314 in the state of being aligned with the accommodation space 314. Thus, even if part of the shield 322 is inclined relative to the accommodation space 314, the shield 322 can smoothly enter the accommodation space 314 by the horn structure formed by the third guide surface 3131 and by the cooperation of the fourth guide surface 3222 and the third guide surface 3131. The tolerance capability of the socket 320 to the position offset of the shield 322 in the plug 320 can be increased, so as to facilitate the plug-in of the second terminal 321 in the shield 322 and the first terminal 311 in the accommodation space 314.

[0090] That is, during the plug-in of the plug 320 and the socket 310, when the plug 320 is inclined relative to the socket 310, the first guide of the plug 320 is first performed by the cooperation of the first guide surface 3121 on the socket housing 312 and the second guide surface 3221 on the shield 322, which can avoid the impact of the shield 322 and the socket housing 312. Then, the second guide of the shield 322 in the plug 320 is performed by the cooperation of the third guide surface 3131 on the partition 313 and the fourth guide surface 3222 on the shield 322, which can avoid the impact of the shield 322 and the partition 313. After two guides during the plug-in of the plug 320 and the socket 310, the tolerance capability of the socket 320 to the position offset of the plug 320 can be increased, and the tolerance capability of the accommodation space 314 in the socket 310 to the position offset of the shield 322 in the plug 320 can be increased. Thus, the damage of one or more of the socket housing 312, the partition 313, or the shield 322 can be avoided.

[0091] In addition, the first guide surface 3121 is formed on the socket shell 312, and the third guide surface 3131 is formed on the partition 313, both the socket shell 312 and the partition 313 are structures of the socket 310, that is, the guide surfaces are set without adding components to the socket 310, so that the structure of the socket 310 is changed less. The second guide surface 3221 and the fourth guide surface 3222 are both formed on the protective sleeve 322, and the protective sleeve 322 is a structure of the plug 320, that is, the guide surfaces are set without adding components to the plug 320, so that the structure of the plug 320 is simple.

[0092] The computing device provided by the embodiment of the present application sets the first board card 100, the second board card 200 and the connector assembly 300, the connector assembly 300 includes the socket 310 and the plug 320, the socket 310 includes the socket shell 312, the partition 313 and a plurality of first terminals 311, the partition 313 is located in the socket shell 312 and separates the socket shell 312 into a plurality of accommodation spaces 314, and the plurality of first terminals 311 are respectively located in different accommodation spaces 314; the plug 320 includes a plurality of second terminals 321, each second terminal 321 is sleeved with a protective sleeve 322; the socket shell 312 has a first guide surface 3121, and at least part of the protective sleeve 322 has a second guide surface 3221 on a side facing the socket shell 312; the partition 313 has a third guide surface 3131, and the protective sleeve 322 has a fourth guide surface 3222 on a side facing the partition 313. In the process of plugging the plug 320 into the socket 310, first, the second guide surface 3221 cooperates with the first guide surface 3121 to guide the plug 320 for the first time; then the fourth guide surface 3222 cooperates with the third guide surface 3131 to guide the plug 320 for the second time, which can improve the tolerance of the socket 310 to the position deviation of the plug 320.

[0093] Specifically, please continue to refer to Figure 7 As shown in the figure, the protective sleeve 322 includes a first wall portion 3223, the first wall portion 3223 is located on a side of the protective sleeve 322 facing the outside of the arrangement area S, and part of the first wall portion 3223 has a protruding portion 3224 protruding from an end of the protective sleeve 322 (that is, an end facing the first terminal 311), and the second guide surface 3221 is arranged on the protruding portion 3224.

[0094] The cross section of the protective sleeve 322 can be rectangular, and the protective sleeve 322 includes four wall portions, in the protective sleeve 322 close to the socket shell 312, the wall portion of the protective sleeve 322 facing the socket shell 312 is the first wall portion 3223.

[0095] The protruding portion 3224 can be arranged on the first wall portion 3223 and extend toward one side of the first terminal 311 along the third direction Z. The protruding portion 3224 can be used to align the plug 320 and the socket 310 before the plug 320 is plugged into the socket 310. The protruding portion 3224 can be arranged on each of the first wall portions 3223 of the protective sleeve 322 or arranged on some of the first wall portions 3223 of the protective sleeve 322.

[0096] In Figure 7 In the illustrated embodiment, the second guide surface 3221 is arranged on the protruding portion 3224. The plug 320 can be limited by the cooperation between the second guide surface 3221 on the protruding portion 3224 and the first guide surface 3121 on the socket housing 312. Compared with the scheme in which an additional positioning member is arranged to occupy a large space, the space occupied by the plug 320 and the socket 310 in the connector assembly 300 provided in the embodiment of the present application is smaller.

[0097] Figure 13 A schematic view of the cooperation between the plug and the socket in the connector assembly provided in the embodiment of the present application is shown.

[0098] As shown in Figure 13 As shown in FIG. 6, the protruding portion 3224 is arranged on the protective sleeve 322. The end surface of the protective sleeve 322 and the bottom wall 3122 of the socket housing 312 have a gap D1. When the length of the protective sleeve 322 is relatively long, the gap D1 can accommodate the elongated portion of the protective sleeve 322. Therefore, the gap D1 can also avoid the end of the protective sleeve 322 from colliding with the bottom wall 3122 of the socket housing 312. In addition, when the plug 320 is plugged into the socket 310, the greater the size of the protruding portion 3224 along the third direction Z, the greater the angle at which the plug 320 can be inclined relative to the socket 310. That is, the angle at which the plug 320 can be inclined relative to the socket 310 is positively correlated with the size of the protruding portion 3224 along the third direction Z. Therefore, the protruding portion 3224 can further improve the tolerance of the position deviation of the plug 320 relative to the socket 310.

[0099] As shown in Figure 7 As shown in FIG. 6, the protective sleeve 322 includes a second wall portion 3225. The second wall portion 3225 is located on the side of the adjacent protective sleeves 322 that faces each other. The fourth guide surface 3222 is arranged on the second wall portion 3225.

[0100] The wall of the adjacent protective sleeve 322 on the side facing each other is a second wall 3225, and the second wall 3225 faces the partition 313 when the plug 320 is inserted into the socket 310. Since the socket housing 312 is provided with a plurality of partitions 313 extending in different directions, the wall facing each partition 313 is the second wall 3225. The fourth guide surface 3222 is arranged on the second wall 3225, and the fourth guide surface 3222 is arranged by the structure of the protective sleeve 322 itself, so that no additional structure needs to be added to the protective sleeve 322 to arrange the second guide surface 3222.

[0101] In a possible implementation, the thickness of the first wall 3223 is greater than the thickness of the second wall 3225.

[0102] The first wall 3223 can be thickened, for example, the thickness of the first wall 3223 can be increased by 0.2-0.3mm, thereby the strength of the protrusion 3224 arranged on the first wall 3223 can be increased. The thickness of the second wall 3225 remains unchanged, thereby the volume of the protective sleeve 322 can be avoided to be increased due to the increase of the thickness of the second wall 3225.

[0103] In a possible implementation, the distance between the protective sleeves 322 is greater than or equal to 1.5 times the thickness of the partition 313.

[0104] Please continue to see Figure 13 As shown, the protective sleeves 322 have a distance D2 therebetween, and even if part of the protective sleeve 322 is tilted or offset, as long as the tilt or offset range of the protective sleeve 322 is within the range of the distance D2, the protective sleeve 322 can be smoothly inserted into the accommodating space 314. The partition 313 has a thickness D3, and increasing the distance D2 between the protective sleeves 322 to be greater than 1.5 times the thickness D3 can increase the range of the tilt or offset of the protective sleeve 322, and further increase the tolerance capability between the socket 310 and the plug 320.

[0105] Figure 14 The structure diagram of the protective sleeve and the second terminal in the connector assembly provided by the embodiment of the present application is shown in Figure 14 The second terminal 321 is removed from the protective sleeve 322.

[0106] Please see Figure 14 As shown, the second terminal 321 has a hook 3211 on the end away from the first terminal 311, and the hook 3211 abuts against the inner wall of the protective sleeve 322.

[0107] The second terminal 321 has a clasp 3211 on one end away from the first terminal 311, and the distance between the two clasps 3211 is smaller than the distance between the two opposite inner walls of the protective sleeve 322. When the second terminal 321 is installed in the protective sleeve 322, the two opposite inner walls of the protective sleeve 322 compress the clasps 3211, the clasps 3211 are elastically deformed, and the clasps 3211 abut against the inner walls of the protective sleeve 322 by the rebound force of the elastically deformed clasps 3211. The friction between the clasps 3211 and the inner walls of the protective sleeve 322 can prevent the second terminal 321 from being fixed in the protective sleeve 322. The thickness of the first wall portion 3223 of the protective sleeve 322 is increased, and the outer contour of the protective sleeve 322 remains unchanged, so that the distance between the two inner walls of the protective sleeve 322 is reduced. Thus, the two inner walls increase the amount of elastic deformation of the clasps 3211, and the friction between the clasps 3211 and the inner walls of the protective sleeve 322 is greater, so that the second terminal 321 can be more reliably fixed in the protective sleeve 322.

[0108] Please continue to refer to Figure 6 and Figure 8 As shown in Figs. 9 and 10, the socket 310 further includes first foolproof portions 316 connected with the partition 313 near the second end face 3132, and the protective sleeve 322 is provided with second foolproof portions 3226 located on the side of the protective sleeve 322 away from the second terminal 321, and the second foolproof portions 3226 are matched with the first foolproof portions 316.

[0109] The first foolproof portions 316 can be located in the accommodation space 314, and the shapes or sizes of the first foolproof portions 316 are different. The protective sleeve 322 is provided with the second foolproof portions 3226, which can be chamfers on the protective sleeve 322. The shapes of the second foolproof portions 3226 and the corresponding first foolproof portions 316 are matched, and the matching of the second foolproof portions 3226 and the first foolproof portions 316 during plugging can prevent the plug 320 from being inserted reversely.

[0110] Figure 15 Another structural schematic view of the connector assembly provided by the embodiments of the present application is shown in Fig. 11; Figure 16 Fig. 12 is an exploded schematic view of the connector assembly shown in Fig. 11. Figure 15 Fig. 13 is a schematic view of the connector assembly shown in Fig. 11. Figure 15 Fig. 14 is a schematic view of the connector assembly shown in Fig. 11. Figure 16 Fig. 15 is a schematic view of the connector assembly shown in Fig. 11.

[0111] Please refer to Figure 15 and Figure 16 As shown in Figs. 9 and 10, the socket 310 further includes first foolproof portions 316 connected with the partition 313 near the second end face 3132, and the protective sleeve 322 is provided with second foolproof portions 3226 located on the side of the protective sleeve 322 away from the second terminal 321, and the second foolproof portions 3226 are matched with the first foolproof portions 316.

[0112] The mounting portion 3231 is located in the mounting groove 331 to connect the plug 320 with the mounting base 330, and the mounting base 330 can be mounted on the mounting plate 400 by the fastener 600. Figure 2 ) on the mounting plate 400.

[0113] The inner space of the mounting groove 331 can be larger than the peripheral contour of the mounting portion 3231, and there is a gap between the mounting portion 3231 and the side plate of the mounting groove 331, so that the plug 320 can move in a small range relative to the mounting base 330. Thus, when the plug 320 and the socket 310 are not completely aligned, the small movement of the plug 320 can facilitate the alignment of the plug 320 and the socket 310.

[0114] Please continue to refer to Figure 15 and Figure 16 It is shown that the mounting portion 3231 has a limiting protrusion 3232, and the side plate of the mounting groove 331 has a limiting hole 332, the limiting protrusion 3232 is inserted into the limiting hole 332, and the limiting protrusion 3232 and the limiting hole 332 are in clearance fit.

[0115] The limiting protrusion 3232 is inserted into the limiting hole 332, and the limiting protrusion 3232 and the limiting hole 332 can also be in clearance fit, so that by twice clearance fit, the plug 320 can be connected with the mounting base 330 in a floating manner while reducing the movement range of the plug 320. In addition, the dimensional accuracy requirement of the mounting groove 331 and the mounting portion 3231 can be reduced to reduce the processing cost of the connector assembly 320.
