[0061] The connector and the connector assembly utilize the first locking member 5 to lock multiple first terminals 3 simultaneously, simplify the structure of the connector and the connector assembly, thereby reducing the assembly difficulty of the connector and the connector assembly, and the first locking member 5 having the pre-assembly position and the final locking position can be assembled on the insulating body 1 in advance when the first terminal 3 is not inserted into the insulating body 1, thereby preventing the first locking member 5 from being lost.

The insulating body 1 further has a second mounting hole 11 formed therein, and the second terminal 2 is detachably inserted into the second mounting hole 11. The second mounting hole 11 is provided with a second fastener 13, and the first mounting hole 12 is provided with a first fastener 14. The second fastener 13 is used to lock the second terminal 2 at a preset position of the second mounting hole 11, and the first fastener 14 is used to lock the first terminal 3 at a preset position of the first mounting hole 12.

The second locking member 4 in the pre-locked position allows the second terminal 2 to be inserted into the second mounting hole 11, and the second locking member 4 in the final-locked position keeps the second fastener 13 locked to the second terminal 2.

[0066] The connector described above uses the second fastener 13 to lock the second terminal 2 once, and then uses the second locking member 4 to limit the second fastener 13, so that the second fastener 13 keeps the second terminal 2 locked, thereby improving the stability of the connection between the second terminal 2 and the insulating body 1. The first fastener 14 locks the first terminal 3 once, and the first locking member 5 locks the first terminal 3 twice, thereby improving the stability of the connection between the first terminal 3 and the insulating body 1, and thus improving the assembly stability of the entire connector.

Figure 1 Figure 1 ​The second mounting hole 11 and the first mounting hole 12 are arranged in two rows symmetrically along the Y direction and the reverse direction of the Y direction, 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. Any row of the first mounting hole 12 includes three first mounting holes 12 arranged at intervals along the third direction. The number of the first terminal 3 is the same as the number of the first mounting hole 12, and is also six. At this time, the first locking piece 5 moving along the third direction can lock multiple first terminals 3 at the same time. The second direction is perpendicular to the first direction and the third direction.

[0070] Exemplarily, the number of the second mounting hole 11 is one, and the number of the first mounting hole 12 is six. The six first mounting holes 12 are arranged along the second direction (Y direction) at intervals. Figure 1 The second mounting hole 11 and the first mounting hole 12 are arranged in two rows symmetrically along the Y direction and the reverse direction of the Y direction, 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. Any row of the first mounting hole 12 includes three first mounting holes 12 arranged at intervals along the third direction. The number of the first terminal 3 is the same as the number of the first mounting hole 12, and is also six. At this time, the first locking piece 5 moving along the third direction can lock multiple first terminals 3 at the same time. The second direction is perpendicular to the first direction and the third direction.

The first stop surface 151 can abut against the first abutting surface 211 on the second terminal 2, so as to limit the second terminal 2 from continuing to move towards the fourth aperture 112, and make the second terminal 2 inserted to the preset position of the second mounting hole 11.

[0072] Specifically, reference is made to FIG. 1 and FIG. 2. Figure 5 and Figure 12 As shown in FIG. 1 and FIG. 2, the inner wall surface of the second mounting hole 11 is provided with two first limiting blocks 15 relative to each other along the second direction. The first stop surface 151 is formed on the inner side of the first limiting block 15 and is arranged to gradually move away from the hole wall of the second mounting hole 11 from the end close to the third aperture 111 to the end away from the third aperture 111. Correspondingly, the first abutting surface 211 is also arranged to be inclined.

[0075] Specifically, two second fasteners 13 are symmetrically arranged in the second mounting hole 11 in the third direction to improve the locking stability of the second fastener 13 to the second terminal 2. More specifically, the two second fasteners 13 are arranged in the two gaps formed by the two first limiting blocks 15 and connected with the first limiting blocks 15 to improve the structural strength of the second fastener 13.

[0078] After the second terminal 2 connected with the second cable 10 is inserted into the second mounting hole 11, the end cover 30 is mounted on the insulating main body 1, which can reduce the possibility of the second cable 10 shaking and improve the stability of the entire connector. Specifically, the end cover 30 is snap-connected with the insulating main body 1 to facilitate the maintenance and replacement of the second terminal 2.

Reference Figure 6 and Figure 7As shown, when the second locking member 4 is in the pre-locked position, the second locking member 4 is spaced apart from the second fastener 13 in the first direction, and the second locking member 4 does not interfere with the deformation of the second fastener 13, so that the second terminal 2 can be inserted into the preset position of the second mounting hole 11 from the third aperture 111; when the second locking member 4 is in the final locked position, the second fastener 13 moves along the first direction to the second terminal 2, and the inner side of the insertion part 42 abuts against the side of the second fastener 13 away from the second terminal 2, and the second fastener 13 no longer has the ability to deform towards the hole wall of the second mounting hole 11 and is always clamped to the second terminal 2, thereby maintaining the stability of the second terminal 2 inserted into the second mounting hole 11. It is worth emphasizing that when the second 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 opening, limiting the further movement of the second locking member 4 towards the third aperture 111.

[0084] Specifically, one end of the insertion part 42 inserted into the second mounting hole 11 is formed with a stepped surface 421, and when the second locking member 4 is in the final locked position, the second fastener 13 abuts against the stepped surface 421 to determine the final locked position of the second locking member 4, further reducing the possibility of over-insertion of the second locking member 4 into the second mounting hole 11.

[0085] Meanwhile, the side of the second locking member 4 facing the second terminal 2 is also provided with a second stop surface 422, which gradually moves away from the hole wall of the second mounting hole 11 from the end close to the third aperture 111 to the end away from the third aperture 111, and the outer wall surface of the second terminal 2 is formed with a second abutting surface 213 cooperating with the second stop surface 422. When the second locking member 4 is in the final locked position, the second stop surface 422 abuts against the second abutting surface 213, cooperating with the first stop surface 151 and the first abutting surface 211 to further limit the movement of the second terminal 2 towards the fourth aperture 112.

[0086] More specifically, the second stop surface 422 is oppositely provided with two on the inner side wall of the second 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.

[0087] Reference Figure 5 and Figure 9As shown, in order to facilitate observation of whether the second locking member 4 is in the pre-assembly position or the final locking position, and to improve the stability of the second locking member 4 when assembled on the insulating body 1, one of the second 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 fourth aperture 112, the second 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 fourth aperture 112, the second locking member 4 is in the final locking position.

[0088] Exemplarily, the first positioning block 17 is provided on the insulating body 1, and the first slot hole 43 is provided on the second 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 in and out of the first slot hole 43.

[0089] Referring to Figure 14 As shown, in order to reduce the difficulty of the second locking member 4 from the insulating body 1, the sleeve portion 41 is formed with a relief notch 411 extending to the end face of the sleeve portion 41 close to the second terminal 2 along the first direction. When disassembling the second 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.

[0090] Referring to Figure 8 As shown, the first mounting hole 12 has a first aperture 121 and a second aperture 122 oppositely arranged along the first direction, wherein the first aperture 121 is located on the same side of the third aperture 111 of the insulating body 1, and the first mounting hole 12 is provided with a third stop surface 161 close to the second aperture 122, which can abut against the third abutting surface 33 on the first terminal 3, thereby limiting the first terminal 3 to continue moving in the direction of the second aperture 122, so that the first terminal 3 is inserted into the pre-set position of the first mounting hole 12.

[0091] Specifically, the first mounting hole 12 is provided with an annular second limiting block 16 close to the second aperture 122, and the third stop surface 161 is formed on the side of the second limiting block 16 away from the second aperture 122 and is provided as a tapered surface, which gradually expands from the end close to the second aperture 122 to the end away from the second aperture 122. The outer wall surface of the first terminal 3 is formed with a tapered third abutting surface 33, and when the third abutting surface 33 abuts against the third stop surface 161, the first terminal 3 is inserted into the pre-set position of the first mounting hole 12.

[0092] Referring to Figure 8 and Figure 17As shown, the outer wall surface of the first terminal 3 is provided with a second recess 31, the first 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 first orifice 121 is connected with the hole wall of the first mounting hole 12, the other end gradually moves away from the hole wall of the first mounting hole 12 in the direction of the second orifice 122, the second clamping block 142 is arranged on the side of the second elastic arm 141 away from the hole wall of the first mounting hole 12, and the second clamping block 142 is in clamping cooperation with the second recess 31. Specifically, the second recess 31 is a groove opened in the outer wall surface of the first terminal 3.

[0093] After the first terminal 3 is inserted into the first mounting hole 12 from the first orifice 121, the first fastener 14 can be pressed, the second elastic arm 141 is deformed to drive the second clamping block 142 to move in the direction of the hole wall of the first 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 first terminal 3 is locked under the cooperation of the first fastener 14.

[0094] In this embodiment, the side of the second clamping block 142 facing the first orifice 121 is also provided with a second guide surface, the second guide surface gradually inclines in the direction of the center of the first mounting hole 12 from the side close to the first orifice 121, so as to reduce the difficulty of the end of the first terminal 3 inserted into the first mounting hole 12 moving in the direction of the second orifice 122 over the second clamping block 142.

[0095] 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 first terminal 3.

[0096] The first locking member 5 is inserted into the insulating body 1 from the side away from the second terminal 2 along the reverse direction of the third direction. Referring to Figure 10 、 Figure 11 and Figure 16 As shown, the avoiding grooves 513 penetrate through the first locking member 5 along the first direction, and the plurality of avoiding grooves 513 are arranged at intervals along the third direction.

[0097] In order to avoid the first locking member 5 when the first locking member 5 moves along the third direction, the first terminal 3 is provided with a displacement groove 32, and the plurality of displacement grooves 32 on each first terminal 3 are arranged along the third direction.

[0098] Taking the case that the first terminals 3 are symmetrically and spaced apart along the second direction by two, and continuing to refer to Figure 16As shown, the first locking member 5 comprises a connecting portion 52 and two cantilever portions 51, which are respectively arranged on opposite sides of the connecting portion 52 along the second direction and are perpendicular to the connecting portion 52, so that the first 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 first terminals 3 being in the pre-assembly position, each avoidance groove 513 on the cantilever portion 51 corresponds to each first terminal 3 one by one, without affecting the insertion or disengagement of the first terminal 3 from the first mounting hole 12. When the cantilever portions 51 are continuously inserted into the insulating body 1 to the first terminals 3 being in the final locking position, each avoidance groove 513 is staggered with each first terminal 3, thereby limiting the movement of the first terminal 3 in the direction of the second aperture 122.

[0099] Reference Figure 13 As shown, in order to provide guidance to the first terminals 3 when the first terminals 3 are 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 first mounting holes 12. The two cantilever portions 51 are respectively inserted into the insulating body 1 along the two fixed grooves 18.

[0100] Further, in order to facilitate the observation of whether the first locking member 5 is in the pre-assembly position or the final locking position, and to improve the stability of the first locking member 5 when it is assembled on the insulating body 1, one of the first 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. Two second slot holes 19 are arranged in the direction of the insertion of the first locking member 5 into the insulating body 1. When the second positioning block 514 is limited in one of the two second slot holes 19 away from the second terminal 2, the first 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 second terminal 2, the first locking member 5 is in the final locking position.

[0101] Exemplarily, the second positioning block 514 is arranged on the cantilever portion 51 of the first locking member 5, and the second positioning block 514 is arranged on the slot side wall of the two fixed grooves 18 respectively.

[0102] 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 first 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 first 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 first 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 clearance hole 515 is also arranged on the installation part 512. It can be understood that the arrangement of the clearance hole 515 reduces the material cost of manufacturing the first locking piece 5.

[0103] More specifically, in order to reduce the difficulty of disassembling the first locking piece 5, the connecting part 52 is further provided with a force applying slot 521 for facilitating force application.

[0104] Reference Figure 3 and Figure 8 As shown, the connector further includes a first sealing ring 8 arranged at the second aperture 122 of the first installation hole 12 and provided with a through hole 84 for the second cable 10 to pass through. The first sealing ring 8 can block the gap between the second aperture 122 and the first terminal 3, thereby achieving the dustproof and waterproof effect.

[0105] Reference Figures 1-3 As shown, the connector further includes a housing 6 fixedly sleeved on the insulating main body 1 for protecting the insulating main body 1. There is a gap between the housing 6 and the insulating main body 1 for the insertion of the mating connector. Specifically, the housing 6 has an inner cavity open on the opposite side in the first direction, and the insulating main body 1 is located in the inner cavity of the housing 6. 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 first locking piece 5. A force in the direction of the second terminal 2 can be applied to the first locking piece 5 through the operation hole 61, so that the first locking piece 5 is switched from the pre-assembly position to the final locking position.

[0106] It is worth emphasizing that the size of the operation hole 61 in the second direction is smaller than the length of the connecting part 52 in the second direction, in other words, the area of the normal projection of the first 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 first locking piece 5 from being separated from the insulating main body 1 or being squeezed to the final locking position in the operation hole 61 during transportation.

[0107] Specifically, reference Figure 9 , Figure 22 and Figure 23As shown, the housing 6 is provided with a third slot hole 62, and the insulation 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 achieve the detachable fixed connection between the insulation 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 insulation body 1, and an 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 insulation body 1, and the third positioning block 120 is provided on the housing 6.

[0108] Reference Figure 16 As shown, the third aperture 111 and the first aperture 121 on the insulation body 1 are both 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 second mounting hole 11 and the first mounting hole 12 for the first cable 20 and the second cable 10 to pass out, and the docking connector can be electrically connected with the connector from the open end of the housing 6.

[0109] There is a gap between the end of the insulation body 1 close to the open end of the housing 6 and the housing 6 to allow the docking connector to be inserted. In order to lock the docking 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.

[0110] Specifically, referring to Figure 19 and Figure 22 As shown, the third fastener 64 comprises a third elastic arm 641 and a third recess 643, the third elastic arm 641 is connected to the inner wall of the housing 6, and the third recess 643 is provided at an end of the third elastic arm 641 extending towards the slot direction, and the docking connector is formed with a third clamping block matched with the third recess 643, and the third clamping block can be clamped into the third recess 643 to lock the docking connector.

[0111] More specifically, the third elastic arm 641 is provided with two spaced apart along the third direction, and the two third elastic arms 641 are connected by a connecting rod 642 to form the above-mentioned third recess 643 between the two third elastic arms 641, and the third clamping block is clamped into the third recess 643 and abuts against the connecting rod 642.

[0112] Reference Figure 19 and Figure 23As shown, the closed end of the shell 6 is formed with a jack 65 for the third fastener 64 to extend into the inner cavity of the shell 6, the jack 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 jack 65 through a fulcrum, and the end of the third elastic arm 641 connected with the connecting rod 642 extends into the inner cavity of the shell 6 from the jack 65, and the other end is located outside the shell 6. When unlocking 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.

[0113] In order to further improve the stability between the connector and the docking connector, the connector further comprises a third locking member 7, which 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 preset position in the shell 6, and the third locking member 7 in the final locking position keeps the third fastener 64 locked to the docking connector.

[0114] 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 in 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, and 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 in the locking groove 72 and abut against the groove bottom of the locking groove 72.

[0115] Referring to Figure 21 and Figure 23 As shown, in order to improve the stability of the assembly of the third locking member 7 on the shell 6, one of the third locking member 7 and the shell 6 is further provided with a fourth positioning block 66, and the other is provided with a fourth slot hole 731 matched with the fourth positioning block 66, the fourth slot hole 731 is spaced apart in the first direction. When the fourth positioning block 66 is clamped in one of the two fourth slot holes 731 away from the opening end of the shell 6, the fourth locking member is in the pre-assembly position; when the fourth positioning block 66 is clamped in one of the two fourth slot holes 731 close to the opening end of the shell 6, the fourth locking member is in the final locking position.

[0116] 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 comprises two positioning arms 73 arranged on opposite sides of the locking arm 71 along the third direction, 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. Meanwhile, in order to reduce the disassembly difficulty of the third locking member 7, the third locking member 7 further comprises a push-pull plate 74 connected with the end of the locking arm 71 and the positioning arm 73 outside the shell 6.

[0117] With reference to the foregoing Figure 23 As shown, in order to facilitate the force applied to the third fastener 64, thereby making the docking connector disengage from the connector, the two ends of the two third elastic arms 641 away from the connecting rod 642, i.e. the two ends of the two third elastic arms 641 outside the shell 6, are connected with a U-shaped connecting block 644, and the two third elastic arms 641 are respectively connected with the two ends of the connecting block 644. By applying pressure to the connecting block 644, the third elastic arm 641 can be moved in the direction away from the third clamping block under the lever action, thereby making the third elastic arm 641 separate 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 fastener 64 do not interfere with each other.

[0118] When the connector is assembled, the first locking member 5 formed by injection molding is first inserted into the insulating body 1 along the third direction, so that the first locking member 5 is in the pre-assembly position. Then, the second sealing ring 9 is sleeved on the insulating body 1, and the second locking member 4 formed by injection molding is inserted into the second mounting hole 11 along the first direction, so that the second locking member 4 is in the pre-assembly position. Then, the first sealing ring 8 is mounted in the mounting groove 110. Then, the shell 6 is sleeved on the insulating body 1, and the third locking member 7 is inserted into the shell 6. Finally, the second terminal 2 and the first terminal 3 are inserted, and the second locking member 4 and the first locking member 5 are pushed to the final locking position when needed.

[0119] When the second terminal 2 needs to be removed from the second mounting hole 11 to replace a new second terminal 2, the second locking member 4 can be removed from the insulating body 1 by means of a tool, and then the second fastening member 13 is pried by means of a tool inserted into the second mounting hole 11 towards the hole wall of the second mounting hole 11, so that the second terminal 2 is separated from the insulating body 1, effectively reducing the cost of fault maintenance; when the first terminal 3 needs to be removed from the first mounting hole 12 to replace a new first terminal 3, the first locking member 5 can be removed from the insulating body 1 by applying a force to the first locking member 5 along the third direction away from the insulating body 1 through the force applying slot 521, and then a force away from the first terminal 3 is applied to the first fastening member 14 by means of a tool inserted into the first mounting hole 12, so that the first fastening member 14 is separated from the first terminal 3, and the first terminal 3 is separated from the insulating body 1; when the mating connector needs to be separated from the connector, the push-pull plate 74 of the third locking member 7 is pressed to separate one end of the third locking member 7 engaged with the third fastening member 64 from the third fastening member 64, and then the third locking member 7 is pulled out of the shell 6, and the connecting block 644 of the third fastening member 64 is pressed to separate one end of the third fastening member 64 engaged with the mating connector from the mating connector, so that the mating connector is pulled out of the shell 6.
