In addition, the terms "first" and "second" are only used to distinguish in description and have no special meaning.

[0061] The embodiment of the present application provides a connector assembly, which comprises a connector and a pair of connecting connectors (not shown in the figure) capable of being matched with the connector. It can be understood that one of the connector and the connecting connector is arranged on a device main body of a device, such as a domain controller or an IVI vehicle-mounted processing device, and the other is connected to another device, such as a laser radar, a gateway and the like, through a cable. The specific structure of the connector will be described in detail below with the cable arranged on the connector as an example.

[0062] Reference Figures 1-3 As shown in the figure, the connector comprises an insulating body 1, a first terminal 2 and a first locking member 4, wherein the insulating body 1 is provided with a first mounting hole 11, the first terminal 2 is inserted into the first mounting hole 11, the first mounting hole 11 is provided with a first fastener 13, the first fastener 13 is in clamping connection with the first terminal 2, so as to lock the first terminal 2 at a preset position of the first mounting hole 11, and the first locking member 4 is detachably inserted into the insulating body 1. The first locking member 4 has a pre-assembly position and a final locking position. The first locking member 4 in the pre-assembly 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 in clamping connection with the first terminal 2.

[0063] The connector and connector assembly described above 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, which improves the stability of the connection between the first terminal 2 and the insulating body 1, and thus helps to maintain the performance of the connector and connector assembly.

[0064] refer to Figures 5-7 As shown, the first mounting hole 11 has a first opening 111 and a second opening 112 disposed opposite to each other along a first direction, with the first opening 111 disposed on the positive side of the second opening 112 along the first direction. The first terminal 2 can be inserted into the first mounting hole 11 through the first opening 111 and moved towards the second opening 112. The first mating terminal on the mating connector that is adapted to the first terminal 2 can be electrically connected to the first terminal 2 through the second opening 112. A first stop surface 151 is provided on the inner wall of the first mounting hole 11 near the second opening 112. The first stop surface 151 can abut against the first abutting surface 211 on the first terminal 2, thereby restricting the first terminal 2 from continuing to move towards the second opening 112, so that the first terminal 2 is inserted into the preset position of the first mounting hole 11.

[0065] Specifically, refer to Figure 5 and Figure 12 As shown, on the inner wall surface of the first mounting hole 11 along the second direction ( Figure 1 Two first limiting blocks 15 are arranged opposite each other in the Y-direction and its opposite direction (where the Y-direction is the positive direction of the second direction and the opposite direction of the Y-direction is the negative direction of the second direction). A first stop surface 151 is formed on the inner side of the first limiting block 15 and is configured to gradually move away from the wall of the first mounting hole 11 from the end near the first opening 111 to the end away from the first opening 111. Correspondingly, the first abutment surface 211 is also inclined, 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. The first fastener 13 includes an integrally formed first elastic arm 131 and a first locking block 132. One end of the first elastic arm 131 near 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 towards the second opening 112. The first locking block 132 is disposed 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 aperture 111, the first fastener 13 can be pressed, the first elastic arm 131 is deformed to drive the first clamping block 132 to move towards the hole wall of the first mounting hole 11, until the first clamping block 132 is clamped into the first recess 221, at this time, the first stop surface 151 abuts against the first abutting surface 211, the first fastener 13 locks the first terminal 2, preventing the first terminal 2 from moving towards the first aperture 111.

[0068] Specifically, the first fastener 13 is arranged in the first mounting hole 11 along the third direction (Z direction) and the reverse direction thereof. Figure 1 The two first fasteners 13 are symmetrically arranged along the middle 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 to the first terminal 2. More specifically, the two first fasteners 13 are arranged in the two gaps formed by the two first limiting blocks 15 respectively and connected with the first limiting blocks 15 to improve the structural strength of the first fastener 13, and the third direction is perpendicular to the first direction and the second direction.

[0069] More specifically, the side of the first clamping block 132 facing the first aperture 111 is provided with a first guide surface, the first guide surface gradually moves away from the hole wall of the first mounting hole 11 from the side close to the first aperture 111 to the side away from the first aperture 111, so as to reduce the difficulty of the end of the first terminal 2 inserted into the first mounting hole 11 moving towards the second aperture 112.

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

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

[0072] Reference Figure 15As shown, the first terminal 2 comprises 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 is crimped with the rear shielding shell 22, the inner conductor is located in the front shielding shell 21 for electrically connecting the first mating terminal and the cable, and 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 face 211 is formed between the large-diameter section and the small-diameter section, the rear shielding shell 22 is provided in the shape of 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 can be understood that in other embodiments, the first recess 221 can be arranged on the first elastic arm 131, and the first clamping block 132 is arranged on the first terminal 2.

[0074] Reference Figure 12 and Figure 15 As shown, in order to prevent the first terminal 2 from being inserted into the first mounting hole 11 too deeply and causing damage to the first terminal 2 or the insulating body 1, in the present embodiment, the inner side surface of the first limiting stopper 15 is further provided with a guide groove 152 extending in the first direction, the side of the guide groove 152 close to the second aperture 112 is closed, and the outer wall surface of the first terminal 2 is provided with a guide block 212 in sliding cooperation with the guide groove 152, and when the first terminal 2 is in the preset position in the first mounting hole 11, the guide block 212 abuts against the groove wall of the guide groove 152 close to the second aperture 112. Specifically, the guide block 212 is arranged 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. Reference Figure 14 As shown, the first locking member 4 comprises a sleeving portion 41 and a plug-in portion 42, the sleeving portion 41 is connected with the plug-in portion 42 and is located outside the plug-in portion 42, a clamping space with an opening direction towards the first aperture 111 is formed between the sleeving portion 41 and the plug-in portion 42, the plug-in portion 42 is inserted into the first mounting hole 11 from the second aperture 112, and the sleeving portion 41 is sleeved on 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 aperture 112. Reference Figure 6 and Figure 7As shown, when the first locking member 4 is in the pre-locked position, the first locking member 4 is spaced apart from the first fastener 13 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 into the first mounting hole 11 from the first aperture 111 to the preset position; when the first locking member 4 is in the final locked position, the first fastener 13 moves along the first direction to the first terminal 2, and the inner side of the insertion part 42 abuts against the side of the first fastener 13 away from the first terminal 2, and the first fastener 13 no longer has the ability to deform towards 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 inserted into the first mounting hole 11. It is worth emphasizing that when the first locking member 4 is in the final locked position, the end face of the insulating body 1 abuts against the side of the clamping space away from the aperture, thereby limiting the further movement of the first locking member 4 towards the first aperture 111.

[0077] Specifically, one end of the insertion part 42 inserted into the first mounting hole 11 is formed with a stepped surface 421, and when the first locking member 4 is in the final locked position, the first fastener 13 abuts against the stepped surface 421 to determine the final locked position of the first locking member 4, thereby further reducing the possibility of over-insertion of the first locking member 4 into the first mounting hole 11.

[0078] Meanwhile, the side of the first locking member 4 facing the first terminal 2 is also provided with a second stop surface 422, and 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 aperture 111 to the end away from the first aperture 111, while the outer wall surface of the first terminal 2 is formed with a second abutting surface 213 cooperating with the second stop surface 422. When the first locking member 4 is in the final locked position, the second stop surface 422 abuts against the second abutting surface 213, and the first stop surface 151 and the first abutting surface 211 cooperate to further limit the movement of the first terminal 2 towards the second aperture 112.

[0079] More specifically, the second stop surface 422 is oppositely provided with two on the inner side wall of the first locking member 4, and correspondingly, the second abutting surface 213 is also provided with two, and 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 jointly constitute a tapered surface connecting the large-diameter section and the small-diameter section.

[0080] Reference Figure 5 and Figure 9As shown, in order to facilitate observation of whether the first locking member 4 is in the pre-assembly position or the final locking position, and to improve the stability of the first locking member 4 when assembled on the insulating body 1, one of the first locking member 4 and the insulating body 1 is further provided with a first positioning block 17, and the other is provided with a first slot hole 43 that is engaged with the first positioning block 17. Two first slot holes 43 are spaced apart along the first direction. When the first positioning block 17 is limited in one of the two first slot holes 43 away from the second aperture 112, the first locking member 4 is in the pre-assembly position. When the first positioning block 17 is limited in one of the two first slot holes 43 close to the second aperture 112, the first locking member 4 is in the final locking position.

[0081] For example, the first positioning block 17 is provided on the insulating body 1, and the first slot hole 43 is provided on the first locking member 4. Specifically, the cross section of the first positioning block 17 is provided as an isosceles trapezoid or an isosceles triangle with a chamfered corner, so as to reduce the difficulty of the first positioning block 17 entering and exiting the first slot hole 43.

[0082] Reference Figure 14 As shown, in order to reduce the difficulty of the first locking member 4 being separated from the insulating body 1, the sleeve portion 41 is formed with a relief notch 411 extending along the first direction to the end surface of the sleeve portion 41 close to the first terminal 2. When disassembling the first locking member 4, a force is applied to the sleeve portion 41 along the second direction away from the insulating body 1, so that the first positioning block 17 is separated from the first slot hole 43.

[0083] The connector further comprises a second terminal 3 and a second locking member 5. The insulating body 1 is provided with a second mounting hole 12, and the second terminal 3 is inserted into the second mounting hole 12. The second mounting hole 12 is provided with a second fastener 14 for locking the second terminal 3 at a predetermined 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-assembly position and a final locking position. The second locking member 5 in the pre-assembly 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 with 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 with the first terminal 2 is a high-speed signal cable. The second terminal 3 is a low-voltage terminal for transmitting low-speed CAN signals, and the second cable 20 connected with the second terminal 3 is a low-voltage cable. In order to adapt to 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 not the same, and the internal space of the first mounting hole 11 is larger than that 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 spaced apart along a third direction (where X is the positive direction of the first direction and the negative direction of X is the negative direction of the first direction). Due to the limitation of the internal space 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 a third direction to switch between the pre-installed position and the final locked position.

[0086] The number of first mounting holes 11 and second mounting holes 12 is not specifically limited in this embodiment. Exemplarily, there is one first mounting hole 11 and six second mounting holes 12, arranged along a second direction (…). Figure 1 The second mounting holes 12 are arranged symmetrically in two rows (where Y is the positive direction of the second direction and the negative direction of Y is the negative direction of the second direction). Each row of the second mounting holes 12 includes three second mounting holes 12 spaced apart along a third direction. The number of second terminals 3 is the same as the number of second mounting holes 12, which is also six. At this time, the second locking member 5, which moves along the third direction, can simultaneously lock multiple second terminals 3. The second direction is perpendicular to the first direction and the third direction.

[0087] refer to Figure 8 As shown, the second mounting hole 12 has a third opening 121 and a fourth opening 122 arranged opposite to each other along a first direction. The third opening 121 and the first opening 111 are located on the same side of the insulating body 1. A third stop surface 161 is provided on the side of the second mounting hole 12 near the fourth opening 122. The third stop surface 161 can abut against the third abutting surface 33 on the second terminal 3, thereby restricting the second terminal 3 from continuing to move towards 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 ring-shaped second limiting block 16 is provided on the side of the second mounting hole 12 near the fourth opening 122. A third stop surface 161 is formed on the side of the second limiting block 16 facing away from the fourth opening 122 and is set as a conical surface. It gradually expands from the end near the fourth opening 122 to the end away from the fourth opening 122. A conical third abutment surface 33 is formed on the outer wall surface of the second terminal 3. When the third abutment 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.

[0089] refer to Figure 8 and Figure 17As shown, the outer wall surface of the second terminal 3 is provided with a second recess 31, the second fastener 14 comprises a second elastic arm 141 and a second clamping block 142 which are integrally formed, one end of the second elastic arm 141 close to the third aperture 121 is connected with the hole wall of the second mounting hole 12, the other end gradually moves away from the hole wall of the second mounting hole 12 in the direction of the fourth aperture 122, and the second clamping block 142 is arranged on the side of the second elastic arm 141 away from the hole wall of the second mounting hole 12. Specifically, the second recess 31 is a groove opened in the outer wall surface of the second terminal 3.

[0090] After the second terminal 3 is inserted into the second mounting hole 12 from the third aperture 121, the second fastener 14 can be pressed, the second elastic arm 141 is deformed to drive the second clamping block 142 to move towards the hole wall of the second mounting hole 12, until the second clamping block 142 is clamped into the second recess 31, at this time, the third stop surface 161 abuts against the third abutting surface 33, and the second terminal 3 is locked by the cooperation of the second fastener 14.

[0091] In this embodiment, the side of the second clamping block 142 facing the third aperture 121 is also provided with a second guide surface, the second guide surface gradually inclines towards the center of the second mounting hole 12 from the side close to the third aperture 121, so as to reduce the difficulty of the end of the second terminal 3 inserted into the second mounting hole 12 moving in the direction of the fourth aperture 122 over the second clamping block 142.

[0092] It can be understood that the positions of the second recess 31 and the second clamping 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 from the side away from the first terminal 2 along the reverse direction of the third direction. Referring to Figure 10 、 Figure 11 and Figure 16 As shown, the second locking member 5 is provided with an avoiding slot 513 penetrating along the first direction, the avoiding slot 513 on the second locking member 5 in the pre-locked position is opposite to the second terminal 3, so as to allow the second terminal 3 to be inserted into or separated from the second mounting hole 12, and the avoiding slot 513 on the second locking member 5 in the final locked position is staggered with 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 giving slot 32. Based on the premise that the second terminal 3 is arranged in line along the third direction, the plurality of giving slots 32 on each second terminal 3 are arranged along the third direction, and the second locking member 5 is provided with the same number of avoiding slots 513 as the second terminal 3.

[0095] Taking the second terminal 3 as an example which is symmetrically and spacedly arranged in two rows along the second direction, continuing to refer to Figure 16As shown, the second locking member 5 comprises a connecting portion 52 extending along the second direction and two cantilever portions 51 respectively arranged on opposite sides of the connecting portion 52 and perpendicular to the connecting portion 52, so that the second locking member 5 is approximately U-shaped. The avoidance grooves 513 are arranged on the cantilever portions 51. When the cantilever portions 51 are inserted into the insulating body 1 to the pre-assembly position of the second terminal 3, each avoidance groove 513 on the cantilever portion 51 corresponds to each second terminal 3 one by one, without affecting the insertion or disengagement of the second terminal 3 into the second mounting hole 12. When the cantilever portions 51 are continuously inserted into the insulating body 1 to the final locking position of the second terminal 3, each avoidance groove 513 is staggered with each second terminal 3, thereby limiting the movement of the second terminal 3 in the direction of the fourth aperture 122.

[0096] Reference Figure 13 As shown, in order to provide guidance to the second terminal 3 when the second terminal 3 is inserted into the insulating body 1, two fixed grooves 18 extending along the third direction are arranged on the outer wall of the insulating body 1, and the two fixed grooves 18 respectively communicate with the two rows of second mounting holes 12. The two cantilever portions 51 are respectively inserted into the insulating body 1 along the two fixed grooves 18.

[0097] Further, in order to facilitate observation of whether the second locking member 5 is in the pre-assembly position or the final locking position, and to improve the stability of the second locking member 5 when assembled on the insulating body 1, one of the second locking member 5 and the insulating body 1 is further provided with a second positioning block 514, and the other is provided with a second slot hole 19 matched with the second positioning block 514. The second slot hole 19 is spaced apart along the third direction, and the second positioning block 514 is limited in one of the two second slot holes 19 away from the first terminal 2, and the second locking member 5 is in the pre-assembly position. When the second positioning block 514 is limited in one of the two second slot holes 19 close to the first terminal 2, the second locking member 5 is in the final locking position.

[0098] Exemplarily, the second positioning block 514 is arranged on the cantilever portion 51 of the second locking member 5, and the second positioning block 514 is arranged on the cantilever portion 51 of the second locking member 5. The second slot hole 19 corresponding to the second positioning block 514 is arranged on the groove side wall of the two fixed grooves 18, respectively.

[0099] In order to reduce the difficulty of the second positioning block 514 entering the second slot hole 19, the second positioning block 514 is designed in a triangular shape, and the second locking piece 5 is further provided with a strip-shaped clearance hole 515 extending in the third direction, which provides a clearance space for the deformation of the second locking piece 5 when the second positioning block 514 enters the second slot hole 19. Specifically, the cantilever part 51 further includes an installation part 512 and a locking part 511 arranged in an L shape, both of which are connected to the connecting part 52. The installation part 512 can slide in the fixed slot 18, and the locking part 511 is inserted into the second installation hole 12. The second positioning block 514 and the clearance groove 513 are arranged on the installation part 512 and the locking part 511 respectively, and the strip-shaped clearance hole 515 extending in the third direction is arranged on the installation part 512 to enhance the plasticity of the second locking piece 5, reduce the difficulty of switching between the pre-assembly position and the final locking position of the second locking piece 5, and reduce the material cost of manufacturing the second locking piece 5.

[0100] More specifically, in order to reduce the difficulty of disassembling the second locking piece 5, the connecting part 52 is further provided with a force applying groove 521 for facilitating force application, which extends to the surface of the connecting part 52 in the opposite direction of the first direction.

[0101] Reference Figure 3 and Figure 8 As shown in FIG. 9, the connector further includes a first sealing ring 8 arranged at the fourth aperture 122 of the second installation hole 12 and provided with a through hole 84 for passing the second cable 20, which can block the gap between the fourth aperture 122 and the second terminal 3, thereby achieving dustproof and waterproof effects.

[0102] Reference Figure 24 As shown in FIG. 9, based on the premise that multiple second installation holes 12 are arranged on the second terminal 3, the first sealing ring 8 is a group sealing ring provided with multiple through holes 84 corresponding to the multiple second installation holes 12. Specifically, the insulating main body 1 is provided with an installation groove 110 communicating with the second installation holes 12, and the first sealing ring 8 is installed in the installation groove 110. In order to improve the sealing performance of the first sealing ring 8, the first sealing ring 8 includes a sealing main body 83 and multiple first annular protrusions 81 arranged on the outer wall surface of the sealing main body 83 in the first direction, which are arranged in a ring shape to increase the contact area with the groove side wall of the installation groove 110 and improve the sealing performance. Meanwhile, multiple second annular protrusions 82 are arranged on the hole wall of each through hole 84 in the first direction, which are also arranged in a ring shape to increase the contact area between the connection and the second cable 20 and improve the sealing performance.

[0103] Reference Figures 1-3As shown, the connector further comprises a housing 6 having an inner cavity open on one side along the first direction, the insulating body 1 is located in the inner cavity of the housing 6, and the housing 6 is used to protect the insulating body 1. The housing 6 is provided with an operation hole 61 communicating with the inner cavity of the housing 6 at a position corresponding to the connecting part 52 of the second locking piece 5, and the force in the direction of the first terminal 2 can be applied to the second locking piece 5 through the operation hole 61 to switch the second locking piece 5 from the pre-assembly position to the final locking position.

[0104] It is worth emphasizing that the size of the operation hole 61 along the second direction is smaller than the length of the connecting part 52 along the second direction, in other words, the projection area of the second locking piece 5 in the direction of the operation hole 61 is larger than the area of the operation hole 61, so as to prevent the second locking piece 5 from being separated from the insulating body 1 or being pressed to the final locking position from the operation hole 61 during transportation.

[0105] Specifically, referring to Figure 22 and Figure 23 As shown, the housing 6 is provided with a third slot hole 62, and the insulating body 1 is provided with a third positioning block 120 matched with the third slot hole 62, and the third positioning block 120 is limited in the third slot hole 62 to realize the detachable fixed connection between the insulating body 1 and the housing 6. More specifically, the third slot hole 62 is symmetrically provided with two on the housing 6 along the third direction, and the third positioning block 120 is also provided with two to improve the stability of the connection between the housing 6 and the insulating body 1, and the end of the third positioning block 120 away from the slot of the housing 6 is formed with an inclined third guide surface to reduce the difficulty of the third positioning block 120 being clamped into the third slot hole 62. Of course, the third slot hole 62 can also be provided on the insulating body 1, and the third positioning block 120 is provided on the housing 6.

[0106] Referring to Figure 16 As shown, the first aperture 111 and the third aperture 121 on the insulating body 1 are both closed towards the closed end of the housing 6, and the closed end of the housing 6 is provided with a plurality of through holes 63 corresponding to the positions of the first mounting hole 11 and the second mounting hole 12 for the first cable 10 and the second cable 20 to pass out, and the butt connector can be electrically connected with the connector from the open end of the housing 6.

[0107] There is a gap between the end of the insulating body 1 close to the open end of the housing 6 and the housing 6 to allow the butt connector to be inserted. In order to lock the butt connector on the connector, the housing 6 further comprises a third fastener 64 provided on the inner wall of the housing 6, and the third fastener 64 is matched with the connector.

[0108] Specifically, referring to Figure 19 and Figure 22As shown, the third fastener 64 comprises a third elastic arm 641 connected to the inner wall of the shell 6 and a third recess 643 provided at an end of the third elastic arm 641 extending towards the slot direction. A third clamping block is formed on the docking connector and cooperates with the third recess 643. The third clamping block can be clamped into the third recess 643 to lock the docking connector.

[0109] More specifically, two third elastic arms 641 are arranged along the third direction and connected by a connecting rod 642 to form the third recess 643 between the two third elastic arms 641. The third clamping block is clamped into the third recess 643 and abuts against the connecting rod 642.

[0110] Referring to Figure 19 and Figure 23 As shown, the closed end of the shell 6 is formed with a insertion hole 65 for the third fastener 64 to extend into the inner cavity of the shell 6. The insertion hole 65 is in communication with the inner cavity of the shell 6. The third elastic arm 641 is connected to the hole wall of the insertion hole 65 at a fulcrum. One end of the third elastic arm 641 connected to the connecting rod 642 extends into the inner cavity of the shell 6, and the other end is located outside the shell 6. To unlock the third fastener 64 to lock the docking connector, only the end of the third elastic arm 641 located outside the shell 6 needs to be pressed.

[0111] To further improve the stability between the connector and the docking connector, the connector further comprises a third locking member 7. The third locking member 7 also has a pre-assembly position and a final locking position. The third locking member 7 in the pre-assembly position allows the docking connector to be inserted into the pre-set position in the shell 6. The third locking member 7 in the final locking position keeps the third fastener 64 locked to the docking connector.

[0112] Continuing to refer to Figure 19 and Figure 20 As shown, the third locking member 7 is inserted into the shell 6 from the closed end of the shell 6 along the first direction. The third locking member 7 comprises a locking arm 71. The end of the locking arm 71 of the third locking member 7 in the pre-assembly position is located on the side of the connecting rod 642 away from the opening of the shell 6. The locking arm 71 of the third locking member 7 in the final locking position abuts against the outer side of the third fastener 64 to limit the movement of the third fastener 64 away from the third clamping block. Specifically, the locking arm 71 is provided with a locking groove 72, and the connecting rod 642 can be clamped into the locking groove 72 and abut against the groove bottom of the locking groove 72.

[0114] Exemplarily, the third slot hole 62 is arranged on the third locking member 7, and the third positioning block 120 is arranged on the shell 6, specifically on the hole wall of the insertion hole 65. Specifically, the third locking member 7 includes two positioning arms 73 spaced apart along the third direction on the opposite sides of the locking arm 71, both of which are connected with the locking arm 71 and inserted into the insertion hole 65, and the third slot hole 62 is arranged on the positioning arm 73. At the same time, in order to reduce the disassembly difficulty of the third locking member 7, the third locking member 7 further includes a push-pull plate 74 connected with the end of the locking arm 71 and the positioning arm 73 outside the shell 6.

By applying pressure to the connecting block 644, the third elastic arm 641 can move in the direction away from the third clamping block under the lever action, so as to separate the third elastic arm 641 from the third clamping block. And the locking arm 71 of the third locking member 7 is inserted into the shell 6 after passing through the connecting block 644, so that the unlocking of the third locking member 7 and the unlocking of the third buckle 64 do not interfere with each other.

[0116] Referring to Figure 3 And Figure 19 As shown, the connector further includes a second sealing ring 9, which is sleeved on the insulating main body 1 and located in the gap formed between the insulating main body 1 and the shell 6. The second sealing ring 9 can abut against the docking connector inserted into the shell 6, realizing the sealing between the docking connector and the insulating main body 1, and further improving the waterproof and dustproof performance of the connector assembly.

[0117] Specifically, a plurality of third annular protrusions 91 and fourth annular protrusions 92 are respectively spaced apart along the first direction on the inner and outer circumferential walls of the second sealing ring 9, so as to increase the contact area between the second sealing ring 9 and the insulating main body 1 and the docking connector, and improve the sealing performance.

[0118] The connector is assembled as follows: the second locking member 5 is inserted into the insulating body 1 along the third direction to make the second locking member 5 in a pre-assembly position, the second sealing ring 9 is sleeved on the insulating body 1, the first locking member 4 is inserted into the first mounting hole 11 along the first direction to make the first locking member 4 in a pre-assembly position, the first sealing ring 8 is mounted in the mounting groove 110, the shell 6 is sleeved on the insulating body 1, the third locking member 7 is inserted into the shell 6, and finally the first terminal 2 and the second terminal 3 are inserted, and the first locking member 4 and the second locking member 5 are pushed to a final locking position when necessary.

[0119] When the first terminal 2 needs to be removed from the first mounting hole 11 to replace a new first terminal 2, the first locking member 4 can be removed from the insulating body 1 by means of a tool, the first locking member 4 is pried in the direction of the hole wall of the first mounting hole 11 by means of a tool inserted into the first mounting hole 11, so that the first terminal 2 is separated from the insulating body 1, and the fault maintenance cost is effectively reduced; when the second terminal 3 needs to be removed from the second mounting hole 12 to replace a new second terminal 3, the second locking member 5 is removed from the insulating body 1 by applying a force to the second locking member 5 in the third direction away from the insulating body 1, and the second locking member 14 is separated from the second terminal 3 by means of a tool inserted into the second mounting hole 12 to apply a force to the second locking member 14 away from the second terminal 3, so that the second terminal 3 is separated from the insulating body 1; when the connector needs to be separated from the mating connector, the third locking member 7 is separated from the third locking member 64 by applying pressure to the push-pull plate 74 of the third locking member 7, and then the third locking member 7 is pulled out of the shell 6, and the third locking member 64 is separated from the mating connector by applying pressure to the connecting block 644 of the third locking member 64, so that the mating connector is pulled out of the shell 6.
