A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0060] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0061] In an embodiment of the present invention, a connector assembly is provided, comprising a connector and a docking connector (not shown in the figure) that can be mated with the connector. It is understandable that one of the connector and the docking connector is arranged on a device body of a device, such as a domain controller or an on-board processing device such as IVI, and the other is connected to another device such as an on-board device such as a laser radar or a gateway through a cable. The following takes the example of a cable being arranged on the connector to describe the specific structure of the connector in detail.

[0062] refer to Figure 1-Figure 3 As shown, the connector includes an insulating body 1, a first terminal 2 and a first locking member 4, wherein a first mounting hole 11 is opened on the insulating body 1, the first terminal 2 is inserted into the first mounting hole 11, a first fastener 13 is arranged in the first mounting hole 11, the first fastener 13 is engaged with the first terminal 2 to lock the first terminal 2 in a preset position of the first mounting hole 11, the first locking member 4 is detachably inserted in the insulating body 1, the first locking member 4 has a pre-installed position and a final locking position, the first locking member 4 in the pre-installed position allows the first terminal 2 to be inserted into the first mounting hole 11, and the first locking member 4 in the final locking position limits the first fastener 13 so that the first fastener 13 remains engaged with the first terminal 2.

[0063] The above-mentioned connector and connector assembly use the first fastener 13 to lock the first terminal 2 once, and then use the first locking member 4 to limit the first fastener 13, so that the first fastener 13 keeps locking the first terminal 2, thereby improving the stability of the connection between the first terminal 2 and the insulating body 1, and thus is beneficial to maintaining the performance of the connector and the connector assembly.

[0064] refer to Figure 5-Figure 7 As shown, the first mounting hole 11 has a first aperture 111 and a second aperture 112 which are arranged opposite to each other along the first direction, and the first aperture 111 is arranged on the positive side of the second aperture 112 along the first direction, and the first terminal 2 can be inserted into the first mounting hole 11 from the first aperture 111 and move toward the second aperture 112. The first docking terminal on the docking connector adapted to the first terminal 2 can be electrically connected to the first terminal 2 through the second aperture 112, and a first stop surface 151 is arranged on one side of the inner wall of the first mounting hole 11 close to the second aperture 112, and the first stop surface 151 can abut against the first abutting surface 211 on the first terminal 2, thereby limiting the first terminal 2 from continuing to move toward the second aperture 112, so that the first terminal 2 is inserted to the preset position of the first mounting hole 11.

[0065] Specifically, refer to Figure 5 and Fig.12 As shown, the inner wall surface of the first mounting hole 11 is along the second direction ( Figure 1 Two first limit blocks 15 are arranged opposite to each other in the Y direction and the reverse direction thereof, wherein the Y direction is the positive direction of the second direction and the reverse direction of the Y direction is the reverse direction of the second direction. The first stop surface 151 is formed on the inner side surface of the first limit block 15 and is arranged to gradually move away from the hole wall of the first mounting hole 11 from the end close to the first hole 111 to the end away from the first hole 111. Correspondingly, the first abutting surface 211 is also arranged obliquely, and the second direction is perpendicular to the first direction.

[0066] refer to Figure 6 and Figure 7 As shown, a first recess 221 is provided on the outer wall surface of the first terminal 2, and the first fastener 13 includes an integrally formed first elastic arm 131 and a first clamping block 132. One end of the first elastic arm 131 close to the first opening 111 is connected to the hole wall of the first mounting hole 11, and the other end gradually moves away from the hole wall of the first mounting hole 11 in the direction of the second opening 112. The first clamping block 132 is arranged on the side of the first elastic arm 131 away from the hole wall of the first mounting hole 11.

[0067] After the first terminal 2 is inserted into the first mounting hole 11 from the first opening 111, it can squeeze the first fastener 13. The first elastic arm 131 deforms and drives the first clamping block 132 to move toward the hole wall of the first mounting hole 11 until the first clamping block 132 is inserted into the first recess 221. At this time, the first stop surface 151 abuts against the first abutting surface 211, and the first fastener 13 locks the first terminal 2 to prevent the first terminal 2 from moving toward the first opening 111.

[0068] Specifically, the first fastener 13 is arranged in the first mounting hole 11 along the third direction ( Figure 1Two first fasteners 13 are symmetrically arranged in the Z direction and the reverse direction thereof, wherein the Z direction is the positive direction of the third direction and the reverse direction of the Z direction is the reverse direction of the third direction, so as to improve the locking stability of the first fastener 13 on the first terminal 2. More specifically, the two first fasteners 13 are respectively arranged in the two gaps formed by the two first limit blocks 15 and connected to the first limit blocks 15 to improve the structural strength of the first fasteners 13, and the third direction is perpendicular to the first direction and the second direction.

[0069] More specifically, a first guide surface is provided on the side of the first block 132 facing the first opening 111, and the first guide surface gradually moves away from the hole wall of the first mounting hole 11 from the side close to the first opening 111 to the side away from the first opening 111, so as to reduce the difficulty of the first terminal 2 inserted into the first mounting hole 11 and moving toward the second opening 112 to pass over the first block 132.

[0070] In this embodiment, in order to reduce the difficulty of inserting the first terminal 2 into the first mounting hole 11, the area of ​​the first opening 111 is larger than the maximum cross-sectional area of ​​the first terminal 2. On this basis, the connector further includes an end cover 30, which is mounted on the insulating body 1 and located on one side of the first opening 111 of the first mounting hole 11, and the end cover 30 is provided with a threading hole for the first cable 10 connected to the first terminal 2 to pass through, and the area of ​​the threading hole is smaller than the area of ​​the first opening 111.

[0071] After the first terminal 2 connected with the first cable 10 is inserted into the first mounting hole 11, the end cap 30 is installed on the insulating body 1, which can reduce the possibility of shaking of the first cable 10 and improve the stability of the entire connector. Specifically, the end cap 30 is snap-connected with the insulating body 1 to facilitate the inspection and replacement of the first terminal 2.

[0072] refer to Fig.15 As shown, the first terminal 2 includes a front shielding shell 21, an inner conductor, a wire clamp and a rear shielding shell 22. The rear end of the front shielding shell 21 is sleeved on the rear shielding shell 22 and crimped with the rear shielding shell 22. The inner conductor is located in the front shielding shell 21 for electrically connecting the first docking terminal and the cable. The wire clamp is located in the rear shielding shell 22 for fixing one end of the cable in the rear shielding shell 22. The front shielding shell 21 is sequentially provided with a small diameter section and a large diameter section in the reverse direction of the first direction. The first abutting surface 211 is formed between the large diameter section and the small diameter section. The rear shielding shell 22 is configured as a dumbbell. The first recess 221 is an annular groove formed on the rear shielding shell 22, and the annular groove is located outside the front shielding shell 21.

[0073] It is understandable that, in other embodiments, the first recess 221 may be disposed on the first elastic arm 131 , while the first clamping block 132 is disposed on the first terminal 2 .

[0074] refer to Fig.12 and Fig.15As shown, in order to prevent the first terminal 2 from being inserted too deeply into the first mounting hole 11, thereby causing damage to the first terminal 2 or the insulating body 1, in this embodiment, the inner side surface of the first limit stopper 15 is further provided with a guide groove 152 extending along the first direction, the side of the guide groove 152 close to the second orifice 112 is closed, and the outer wall surface of the first terminal 2 is provided with a guide block 212 that slidably cooperates with the guide groove 152. When the first terminal 2 is at a preset position in the first mounting hole 11, the guide block 212 abuts against the groove wall of the guide groove 152 at one end close to the second orifice 112. Specifically, the guide block 212 is provided on the outer wall surface of the large diameter section.

[0075] The first locking member 4 is inserted into the first mounting hole 11 along the length direction of the first mounting hole 11, that is, the first locking member 4 is inserted into the first mounting hole 11 along the first direction. Fig.14 As shown, the first locking member 4 includes a sleeve portion 41 and an insert portion 42, the sleeve portion 41 is connected to the insert portion 42 and is located outside the insert portion 42, and a clamping space with an opening toward the first opening 111 is formed between the sleeve portion 41 and the insert portion 42, the insert portion 42 is inserted into the first mounting hole 11 from the second opening 112, and the sleeve portion 41 is sleeved on the outside of the insulating body 1, so that the insulating body 1 is clamped in the clamping space.

[0076] The first locking member 4 is inserted into the first mounting hole 11 from the second opening 112. Figure 6 and Figure 7 As shown, when the first locking member 4 is in the pre-installed position, the first locking member 4 and the first fastener 13 are spaced apart in the first direction, and the first locking member 4 does not interfere with the deformation of the first fastener 13, so that the first terminal 2 can be inserted from the first opening 111 to the preset position of the first mounting hole 11; when the first locking member 4 is in the final locking position, the first fastener 13 moves toward the first terminal 2 along the first direction, and the inner side of the plug-in portion 42 abuts against the side of the first fastener 13 facing away from the first terminal 2. Limited by the plug-in portion 42, the first fastener 13 no longer has the ability to deform in the direction of the hole wall of the first mounting hole 11 and is always clamped to the first terminal 2, thereby maintaining the stability of the first terminal 2 when it is inserted into the first mounting hole 11. It is worth emphasizing that when the first locking member 4 is in the final locking position, the end face of the insulating body 1 abuts against the side of the clamping space away from the opening, limiting the first locking member 4 from continuing to move toward the first opening 111.

[0077] Specifically, a step surface 421 is formed on one end of the plug-in portion 42 inserted into the first mounting hole 11. When the first locking member 4 is in the final locking position, the first fastener 13 abuts against the step surface 421 to determine the final locking position of the first locking member 4, thereby further reducing the possibility of the first locking member 4 being over-inserted into the first mounting hole 11.

[0078] At the same time, a second stop surface 422 is also provided on the side of the first locking member 4 facing the first terminal 2. The second stop surface 422 gradually moves away from the hole wall of the first mounting hole 11 from the end close to the first opening 111 to the end away from the first opening 111, and a second abutting surface 213 cooperating with the second stop surface 422 is formed on the outer wall surface of the first terminal 2. When the first locking member 4 is in the final locking position, the second stop surface 422 abuts against the second abutting surface 213, and cooperates with the first stop surface 151 and the first abutting surface 211 to further limit the movement of the first terminal 2 toward the second opening 112.

[0079] More specifically, two second stop surfaces 422 are relatively arranged on the inner wall of the first locking member 4, and correspondingly, two second abutting surfaces 213 are also arranged. The two second abutting surfaces 213 are also formed between the small diameter section and the large diameter section of the front shielding shell 21, that is, the second abutting surface 213 and the first abutting surface 211 together constitute a conical surface connecting the large diameter section and the small diameter section.

[0080] refer to Figure 5 and Fig. 9 As shown, in order to facilitate observation of whether the first locking member 4 is in the pre-installed position or the final locking position, and to improve the stability of the first locking member 4 when assembled on the insulating body 1, a first positioning block 17 is further provided on one of the first locking member 4 and the insulating body 1, and a first slot 43 that is snap-fitted with the first positioning block 17 is provided on the other, and two first slots 43 are arranged at intervals along the first direction. When the first positioning block 17 is limited to one of the two first slots 43 away from the second orifice 112, the first locking member 4 is in the pre-installed position, and when the first positioning block 17 is limited to one of the two first slots 43 close to the second orifice 112, the first locking member 4 is in the final locking position.

[0081] Exemplarily, the first positioning block 17 is disposed on the insulating body 1, and the first slot 43 is disposed on the first locking member 4. Specifically, the cross section of the first positioning block 17 is configured as an equilateral trapezoid or an equilateral triangle with chamfered corners to reduce the difficulty of the first positioning block 17 entering and exiting the first slot 43.

[0082] refer to Fig.14 As shown, in order to reduce the difficulty of the first locking member 4 being separated from the insulating body 1, a clearance notch 411 is formed on the sleeve portion 41, and the clearance notch 411 extends along the first direction to the end surface of the sleeve portion 41 close to the first terminal 2. When the first locking member 4 is removed, a force is applied to the sleeve portion 41 in the second direction away from the insulating body 1, so that the first positioning block 17 can be separated from the first slot 43.

[0083] The connector further includes a second terminal 3 and a second locking member 5. A second mounting hole 12 is provided on the insulating body 1. The second terminal 3 is inserted into the second mounting hole 12. A second fastener 14 is provided in the second mounting hole 12. The second fastener 14 is used to lock the second terminal 3 at a preset position of the second mounting hole 12. The second locking member 5 is detachably inserted into the insulating body 1. The second locking member 5 also has a pre-installed position and a final locking position. The second locking member 5 in the pre-installed position allows the second terminal 3 to be inserted into or pulled out of the second mounting hole 12. The second locking member 5 in the final locking position can lock the second terminal 3.

[0084] In this embodiment, the first terminal 2 and the second terminal 3 are respectively connected to the first cable 10 and the second cable 20, and the functions of the first terminal 2 and the second terminal 3 are different. For example, the first terminal 2 is a signal terminal for transmitting Ethernet signals, and the first cable 10 connected to the first terminal 2 is a high-speed signal cable, and the second terminal 3 is a low-voltage terminal for transmitting low-speed CAN signals, and the second cable 20 connected to the second terminal 3 is a low-voltage cable. In order to accommodate the first terminal 2 and the second terminal 3, the internal spaces of the first mounting hole 11 and the second mounting hole 12 are different, and the internal space of the first mounting hole 11 is larger than the internal space of the second mounting hole 12.

[0085] Specifically, refer to Figure 1 and Figure 2 As shown, the second mounting hole 12 is also along the first direction ( Figure 1 The first mounting hole 11 and the second mounting hole 12 are arranged in a third direction. Based on the limitation of the internal space size of the second mounting hole 12, in order to reduce the difficulty of assembling the second locking member 5 on the insulating body 1, the second locking member 5 moves along the third direction to realize the switching between the pre-installed position and the final locking position.

[0086] The number of the first mounting holes 11 and the second mounting holes 12 is not specifically limited in the embodiment of the present application. For example, the number of the first mounting holes 11 is 1, the number of the second mounting holes 12 is 6, and the 6 second mounting holes 12 are arranged along the second direction ( Figure 1 The second mounting holes 12 in any row include three second mounting holes 12 spaced apart along the third direction, and the number of the second terminals 3 is the same as the number of the second mounting holes 12, which also includes 6. At this time, the second locking member 5 moving along the third direction can lock multiple second terminals 3 at the same time, and the second direction is perpendicular to the first direction and the third direction.

[0087] refer to Figure 8As shown, the second mounting hole 12 has a third opening 121 and a fourth opening 122 which are arranged opposite to each other along the first direction, wherein the third opening 121 and the first opening 111 are located on the same side of the insulating body 1, and the second mounting hole 12 is provided with a third stop surface 161 on the side near the fourth opening 122, and the third stop surface 161 can abut against the third abutting surface 33 on the second terminal 3, thereby limiting the second terminal 3 from continuing to move in the direction of the fourth opening 122, so that the second terminal 3 is inserted into the preset position of the second mounting hole 12.

[0088] Specifically, a second annular limit stop block 16 is provided on the side of the second mounting hole 12 near the fourth orifice 122, and a third stop surface 161 is formed on the side of the second limit stop block 16 facing away from the fourth orifice 122 and is set to a conical surface, which gradually expands from an end close to the fourth orifice 122 to an end away from the fourth orifice 122, and a conical third abutting surface 33 is formed on the outer wall surface of the second terminal 3. When the third abutting surface 33 abuts against the third stop surface 161, the second terminal 3 is inserted into the preset position of the second mounting hole 12.

At this time, the third stop surface 161 abuts against the third abutting surface 33, and the second terminal 3 is locked with the cooperation of the second fastener 14.

[0091] In this embodiment, a second guide surface is further provided on the side of the second block 142 facing the third opening 121. The second guide surface is gradually inclined from the side close to the third opening 121 toward the center direction of the second mounting hole 12 to reduce the difficulty of the second terminal 3 inserted into the second mounting hole 12 and moving toward the fourth opening 122 to pass over the second block 142.

[0092] It can be understood that the positions of the second recess 31 and the second block 142 can be interchanged between the second elastic arm 141 and the second terminal 3 .

[0093] The second locking member 5 is inserted into the insulating body 1 in the opposite direction of the third direction from the side away from the first terminal 2. Fig.10 , Fig.11 and Fig.16 As shown, the second locking member 5 is provided with an avoidance groove 513 which is arranged to penetrate along the first direction. The avoidance groove 513 on the second locking member 5 in the pre-installed position is opposite to the second terminal 3 to allow the second terminal 3 to be inserted into or disengaged from the second mounting hole 12, while the avoidance groove 513 on the second locking member 5 in the final locking position is offset from the second terminal 3, and the second terminal 3 is locked in the second mounting hole 12.

[0094] In order to avoid the second locking member 5 when the second locking member 5 moves along the third direction, the second terminal 3 is provided with a clearance groove 32.

[0099] In order to reduce the difficulty of the second positioning block 514 entering the second slot 19, the second positioning block 514 is designed to be triangular in shape. At the same time, a strip-shaped clearance hole 515 extending along the third direction is also provided on the second locking member 5. When the second positioning block 514 enters the second slot 19, the clearance hole 515 provides an avoidance space for the deformation of the second locking member 5.

[0104] It is worth emphasizing that the size of the operating hole 61 along the second direction is smaller than the length of the connecting portion 52 along the second direction. In other words, the positive projection area of ​​the second locking member 5 in the direction of the operating hole 61 is larger than the area of ​​the operating hole 61, so as to prevent the second locking member 5 from detaching from the insulating body 1 from the operating hole 61 or being squeezed to the final locking position during transportation.

[0105] Specifically, refer to Fig. 22 and Fig.23 As shown, the shell 6 is provided with a third slot 62, and the insulating body 1 is provided with a third positioning block 120 that is engaged with the third slot 62.

When unlocking the lock of the third fastener 64 on the docking connector, it is only necessary to press the end of the third elastic arm 641 located outside the housing 6.

[0111] In order to further improve the stability between the connector and the docking connector, the connector also includes a third locking member 7, which also has a pre-installed position and a final locking position. The third locking member 7 in the pre-installed position allows the docking connector to be inserted into a preset position in the housing 6, and the third locking member 7 in the final locking position keeps the third fastener 64 locked on the docking connector.
