[0061] The connector and the connector assembly seal the first cable 20 and the insulating body 1 by the first sealing ring 8 and seal the connector and the mating connector by the second sealing ring 9, thereby improving the sealing performance of the entire connector assembly and achieving good dustproof and waterproof effects. Moreover, the first sealing ring 8 can simultaneously seal the plurality of first terminals 3 and the insulating body 1, thereby simplifying the assembly difficulty of the connector and the connector assembly.

[0062] Reference Figure 8 As shown, the side of the insulating body 1 close to the first hole opening 121 is provided with a mounting groove 110 communicating with the first mounting holes 12, and the first sealing ring 8 is embedded in the mounting groove 110 and abuts against the groove wall of the mounting groove 110, and the mounting groove 110 improves the stability of the connection between the first sealing ring 8 and the insulating body 1.

[0063] Reference Figure 24 As shown, in order to improve the sealing performance of the first sealing ring 8, the first sealing ring 8 comprises a sealing body 83 and a plurality of first annular protrusions 81 arranged on the outer wall surface of the sealing body 83 along the length direction of the first mounting hole 12, so as to increase the contact area with the groove side wall of the mounting groove 110 and improve the sealing performance, and a plurality of second annular protrusions 82 are arranged on the hole wall of each through hole 84 along the length direction of the through hole 84, so as to increase the contact area between the first cable 20 and improve the sealing performance. In the embodiment, the length direction of the through hole 84 is consistent with the length direction of the first mounting hole 12, so as to reduce the bending deformation of the first cable 20.

[0064] Reference Figure 25As shown, the inner peripheral wall and the outer peripheral wall of the second sealing ring 9 are respectively provided with a plurality of third annular protrusions 91 and fourth annular protrusions 92 along the length direction of the first mounting hole 12, so as to increase the contact area between the second sealing ring 9 and the insulating body 1 and the mating connector, and improve the sealing performance.

[0065] Reference Figures 1-3 And Figure 6 、 Figure 12 As shown, the connector further comprises a second terminal 2, a second locking member 4 and a first locking member 5, and the first locking member 5, the second locking member 4 and the insulating body 1 are all made by injection molding. The insulating body 1 is further provided with a second mounting hole 11, the second terminal 2 is inserted into the second mounting hole 11, the second mounting hole 11 is provided with a second fastener 13, 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 and the first locking member 5 are detachably inserted into the insulating body 1, and both of them have a pre-assembly position and a final locking position. The second locking member 4 in the pre-assembly position allows the second terminal 2 to be inserted into the second mounting hole 11, and the second locking member 4 in the final locking position makes the second fastener 13 keep locking the second terminal 2. The first locking member 5 in the pre-assembly position allows the first terminal 3 to be inserted into or pulled out of the first mounting hole 12, and the first locking member 5 in the final locking position can lock the first terminal 3.

[0066] The above connector 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 locking the second terminal 2, 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 improving the assembly stability of the whole connector. Moreover, the first locking member 5, the second locking member 4 and the insulating body 1 are all injection molded, so that the first locking member 5 and the second locking member 4 can be assembled on the insulating body 1 in advance and in the pre-assembly position before transportation, thereby reducing the possibility of losing the first locking member 5 and the second locking member 4, and reducing the difficulty of later assembly.

[0067] In this embodiment, the second terminal 2 is connected to the second cable 10, and the second terminal 2 and the first terminal 3 have different functions. For example, if the second terminal 2 is a signal terminal for transmitting Ethernet signals, then the second cable 10 connected to the second terminal 2 is a high-speed signal cable. If the first terminal 3 is a low-voltage terminal for transmitting, for example, low-speed CAN signals, then the first cable 20 connected to the first terminal 3 is a low-voltage cable. To accommodate the second terminal 2 and the first terminal 3, the internal spaces of the second mounting hole 11 and the first mounting hole 12 are different, with the internal space of the second mounting hole 11 being larger than that of the first mounting hole 12.

[0068] It is understandable that, in order to achieve a seal between the second terminal 2 and the insulating body 1, a sealing element that abuts against the insulating body 1 can also be fixedly sleeved on the second terminal 2, which will not be explained further here.

[0069] refer to Figure 1 and Figure 2 As shown, both the second mounting hole 11 and the first mounting hole 12 are along the first direction ( Figure 1 The first mounting hole 11 and the second mounting hole 12 extend along a third direction perpendicular to the first 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), and the second mounting hole 11 and the first mounting hole 12 extend along a third direction perpendicular to the first direction. Figure 1 The Z-direction and its reverse direction (where Z-direction is the positive direction of the third direction and the reverse direction of Z-direction is the reverse direction of the third direction) are spaced apart. Due to the limitation of the internal space of the second mounting hole 11 and the first mounting hole 12, in order to reduce the difficulty of assembling the second locking member 4 and the first locking member 5 on the insulating body 1, the second locking member 4 switches between the pre-installed position and the final locking position by moving along the first direction, and the first locking member 5 switches between the pre-installed position and the final locking position by moving along the third direction.

[0070] For example, there is one second mounting hole 11 and six first mounting holes 12, the six first mounting holes 12 being arranged along the second direction ( Figure 1 The second direction (Y-direction and its reverse direction, where Y-direction is the positive direction of the second direction and the reverse direction of Y-direction is the reverse direction of the second direction) is symmetrically arranged in two rows. Each row has three first mounting holes 12 spaced apart along a third direction. The number of first terminals 3 is the same as the number of first mounting holes 12, which is also six. At this time, the first locking member 5, which moves along the third direction, can simultaneously lock multiple first terminals 3. The second direction is perpendicular to the first direction and the third direction.

[0071] refer to Figures 5-7As shown, the second mounting hole 11 is oppositely provided with a third aperture 111 and a fourth aperture 112 along the first direction, and the third aperture 111 is disposed on the positive side of the fourth aperture 112 along the first direction, and the second terminal 2 can be inserted into the second mounting hole 11 from the third aperture 111 and moved to the direction of the fourth aperture 112. The second mating terminal on the mating connector adapted to the second terminal 2 can be electrically connected with the second terminal 2 through the fourth aperture 112, and the inner wall of the second mounting hole 11 on the side close to the fourth aperture 112 is provided with a first stop surface 151, which can abut against a first abutting surface 211 on the second terminal 2, thereby limiting the second terminal 2 to continue to move in the direction of the fourth aperture 112, and inserting the second terminal 2 to a preset position in the second mounting hole 11.

[0072] Specifically, referring to Figure 5 and Figure 12 As shown, the inner wall surface of the second mounting hole 11 is oppositely provided with two first limiting blocks 15 along the second direction, and the first stop surface 151 is formed on the inner side of the first limiting block 15 and is disposed to gradually 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 inclinedly disposed.

[0073] Referring to Figure 6 , Figure 7 and Figure 15 As shown, the outer wall surface of the second terminal 2 is provided with a first recess 221, and the second fastener 13 includes an integrally formed first elastic arm 131 and a first clamping block 132, the first elastic arm 131 is connected to the hole wall of the second mounting hole 11 at one end close to the third aperture 111, and the other end gradually away from the hole wall of the second mounting hole 11 in the direction of the fourth aperture 112, the first clamping block 132 is disposed on the side of the first elastic arm 131 away from the hole wall of the second mounting hole 11, and the first clamping block 132 is in clamping engagement with the first recess 221.

[0074] After the second terminal 2 is inserted into the second mounting hole 11 from the third aperture 111, the second fastener 13 can be pressed, the first elastic arm 131 is deformed to drive the first clamping block 132 to move to the direction of the hole wall of the second 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, and the second fastener 13 locks the second terminal 2 to prevent the second terminal 2 from moving in the direction of the third aperture 111.

[0075] Specifically, two second fasteners 13 are symmetrically disposed in the second mounting hole 11 along 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 respectively disposed 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.

[0076] More specifically, the first guiding surface is arranged on the side of the first clamping block 132 facing the third aperture 111, and gradually moves away from the hole wall of the second mounting hole 11 from the side close to the third aperture 111 to the side away from the third aperture 111, so as to reduce the difficulty of the second terminal 2 inserted into one end of the second mounting hole 11 moving in the direction of the fourth aperture 112 and passing over the first clamping block 132.

[0077] In the embodiment, in order to reduce the difficulty of the second terminal 2 inserted into the second mounting hole 11, the area of the third aperture 111 is greater than the maximum cross-sectional area of the second terminal 2. On this basis, the connector further comprises a end cover 30, which is mounted on the insulating body 1 and located on the side of the third aperture 111 of the second mounting hole 11, and the end cover 30 is provided with a threading hole for the second cable 10 to pass through, and the area of the threading hole is smaller than the area of the third aperture 111.

[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 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 body 1, so as to facilitate the maintenance and replacement of the second terminal 2.

[0079] Reference Figure 15 As shown, the second 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 pressure-connected with the rear shielding shell 22, the inner conductor is located in the front shielding shell 21 for electrically connecting the second mating terminal and the second cable 10, and the wire clamp is located in the rear shielding shell 22 for fixing one end of the second cable 10 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 arranged 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.

[0080] 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 second terminal 2.

[0081] Reference Figure 12 and Figure 15As shown, in order to prevent the second terminal 2 from being inserted too deep into the second mounting hole 11, causing damage to the second terminal 2 or the insulating body 1, in the embodiment, the inner side surface of the first limiting block 15 is further provided with a guide groove 152 extending in the first direction, the side of the guide groove 152 close to the fourth aperture 112 is closed, and the outer wall surface of the second terminal 2 is provided with a guide block 212 that is in sliding cooperation with the guide groove 152, and when the second terminal 2 is in the preset position in the second mounting hole 11, the guide block 212 abuts against the groove wall of the guide groove 152 close to the fourth aperture 112. Specifically, the guide block 212 is arranged on the outer wall surface of the large-diameter section.

[0082] Referring to Figure 14 As shown, the second locking member 4 includes a sleeve portion 41 and a plug-in portion 42, the sleeve portion 41 is connected with the plug-in portion 42 and located outside the plug-in portion 42, a clamping space with an opening direction towards the third aperture 111 is formed between the sleeve portion 41 and the plug-in portion 42, the plug-in portion 42 is inserted into the second mounting hole 11 from the fourth aperture 112, and the sleeve portion 41 is sleeved on the outside of the insulating body 1, so that the side wall of the insulating body 1 is clamped in the clamping space.

[0083] The second locking member 4 is inserted into the second mounting hole 11 from the fourth aperture 112. Referring to Figure 6 and Figure 7 As shown, when the second locking member 4 is in the pre-assembly position, the second locking member 4 is spaced apart from the second buckle 13 in the first direction, the second locking member 4 does not interfere with the deformation of the second buckle 13, so that the second terminal 2 can be inserted into the second mounting hole 11 to the preset position from the third aperture 111; when the second locking member 4 is in the final locking position, the second buckle 13 moves towards the second terminal 2 along the first direction, the inner side of the plug-in portion 42 abuts against the side of the second buckle 13 away from the second terminal 2, and the second buckle 13 no longer has the ability to deform towards the hole wall of the second mounting hole 11 and is always clamped on 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 locking position, the end surface 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, referring to Figure 14 As shown, one end of the plug-in portion 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 locking position, the second buckle 13 abuts against the stepped surface 421 to determine the final locking position of the second locking member 4, further reducing the possibility of excessive insertion of the second locking member 4 into the second mounting hole 11.

[0085] Meanwhile, the second locking member 4 is further provided with a second stop surface 422 on the side facing the second terminal 2, the second stop surface 422 gradually moves away from the hole wall of the second mounting hole 11 from the end close to the third hole 111 to the end away from the third hole 111, and the outer wall surface of the second terminal 2 is formed with a second abutting surface 213 matched with the second stop surface 422. When the second locking member 4 is in the final locking 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 further limit the movement of the second terminal 2 in the direction of the fourth hole 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, 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] Referring to Figure 5 and Figure 9 , in order to facilitate the 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 matched with the first positioning block 17, the first slot hole 43 is spaced apart along the first direction Two, when the first positioning block 17 is limited in one of the two first slot holes 43 away from the fourth hole 112, the second locking member 4 is in the pre-assembly position, and when the first positioning block 17 is limited in one of the two first slot holes 43 close to the fourth hole 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 , 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 let-in 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 8As shown, the first aperture 121 and the third aperture 111 are located on the same side of the insulating body 1, and the first mounting hole 12 is provided with a third stop surface 161 on the side close to the second aperture 122, which can abut against a third abutting surface 33 on the first terminal 3, thereby limiting the first terminal 3 from moving further in the direction of the second aperture 122 and inserting the first terminal 3 to the preset position of the first mounting hole 12.

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

[0092] Reference Figure 8 and Figure 17 As shown, the outer wall surface of the first terminal 3 is provided with a second recess 31, and the first fastener 14 includes an integrally formed second elastic arm 141 and a second clamping block 142. The one end of the second elastic arm 141 close to the first aperture 121 is connected with the hole wall of the first mounting hole 12, and the other end gradually moves away from the hole wall of the first mounting hole 12 in the direction of the second aperture 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 on 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 aperture 121, the first fastener 14 can be squeezed, 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 aperture 121 is also provided with a second guide surface, which gradually inclines in the direction of the center of the first mounting hole 12 from the side close to the first aperture 121, so as to reduce the difficulty of the one end of the first terminal 3 inserted into the first mounting hole 12 moving in the direction of the second aperture 122 and passing 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 in the reverse direction of the third direction. Referring to Figure 10 、 Figure 11 and Figure 16 , the first locking member 5 is provided with an avoiding slot 513 penetrating in the first direction, the avoiding slot 513 on the first locking member 5 in the pre-assembly position is opposite to the first terminal 3 to allow the first terminal 3 to be inserted into or separated from the first mounting hole 12, while the avoiding slot 513 on the first locking member 5 in the final locking position is offset from the first terminal 3, and the first terminal 3 is locked in the first mounting hole 12.

[0097] In order to avoid the first locking member 5 when the first locking member 5 moves in the third direction, the first terminal 3 is provided with a displacement slot 32. Based on the premise that the first terminal 3 is arranged in line in the third direction, the plurality of displacement slots 32 on each first terminal 3 are arranged in the third direction, and the first locking member 5 is provided with the same number of avoiding slots 513 as the first terminal 3.

[0098] Taking the first terminal 3 as an example, the first terminal 3 is symmetrically spaced in the second direction, and referring to Figure 16 , the first locking member 5 includes a connecting portion 52 and two cantilever portions 51, the connecting portion 52 extends in the second direction, and the two cantilever portions 51 are respectively arranged on the opposite sides of the connecting portion 52 in the second direction and perpendicular to the connecting portion 52, so that the first locking member 5 is approximately U-shaped. The avoiding slot 513 is arranged on the cantilever portion 51, and when the cantilever portion 51 is inserted into the insulating body 1 to the first terminal 3 in the pre-assembly position, each avoiding slot 513 on the cantilever portion 51 corresponds to each first terminal 3 one by one, and does not affect the first terminal 3 to be inserted into or separated from the first mounting hole 12, and when the cantilever portion 51 continues to be inserted into the insulating body 1 to the first terminal 3 in the final locking position, each avoiding slot 513 is offset from each first terminal 3, and the movement of the first terminal 3 in the direction of the second aperture 122 is limited.

[0099] Referring to Figure 13 , in order to provide guidance to the first terminal 3 when the first terminal 3 is inserted into the insulating body 1, the outer wall of the insulating body 1 is provided with two fixing slots 18 extending in the third direction, and the two fixing slots 18 are respectively communicated with two rows of first mounting holes 12, and the two cantilever portions 51 are respectively inserted into the insulating body 1 along the two fixing slots 18.

[0100] Further, in order to facilitate observation of whether the first locking member 5 is in the pre-assembly position or the final locking position, and improve the stability of the first locking member 5 when 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 spaced apart along the third direction. 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 part 51 of the first locking member 5, and the second positioning block 514 is arranged on the cantilever part 51 of the first locking member 5. The second slot hole 19 corresponding to the second positioning block 514 is arranged on the slot side wall of the two fixed slots 18, respectively.

[0102] In order to reduce the difficulty of the second positioning block 514 entering the second slot hole 19, the first locking member 5 is further provided with a strip-shaped accommodation hole 515 extending along the third direction. When the second positioning block 514 enters the second slot hole 19, the accommodation hole 515 provides a space for deformation of the first locking member 5. Specifically, the cantilever part 51 includes an installation part 512 and a locking part 511 arranged in an L shape. The installation part 512 and the locking part 511 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 accommodation groove 513 are arranged on the installation part 512 and the locking part 511, respectively. The accommodation hole 515 is also arranged on the installation part 512. It can be understood that the arrangement of the accommodation hole 515 reduces the material cost of manufacturing the first locking member 5.

[0103] More specifically, in order to reduce the difficulty of disassembling the first locking member 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 in the figures, 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 first cable 20 to pass through. The first sealing ring 8 can block the gap between the second aperture 122 and the first terminal 3, thereby achieving dustproof and waterproof effects.

[0105] Reference Figures 1-3As shown, the connector further comprises a shell 6 fixedly sleeved outside the insulating body 1 for forming protection for the insulating body 1, and a gap exists between the shell 6 and the insulating body 1 for inserting the mating connector. Specifically, the shell 6 has an inner cavity open on the reverse side in the first direction, and the insulating body 1 is located in the inner cavity of the shell 6. The shell 6 is provided with an operation hole 61 communicating with the inner cavity of the shell 6 at a position corresponding to the connecting part 52 of the first locking piece 5, and a force in the direction of the second terminal 2 can be applied to the first locking piece 5 through the operation hole 61 to switch the first locking piece 5 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 orthographic 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 body 1 or being pressed to the final locking position from the operation hole 61 during transportation.

[0107] Specifically, referring to Figure 9 , Figure 22 and Figure 23 As shown, the shell 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 achieve detachable fixed connection between the insulating body 1 and the shell 6. More specifically, the third slot hole 62 is symmetrically provided with two on the shell 6 in the third direction, and the third positioning block 120 is also provided with two to improve the stability of the connection between the shell 6 and the insulating body 1, and an inclined third guide surface is formed at one end of the third positioning block 120 away from the slot of the shell 6 to reduce the difficulty of the third positioning block 120 being inserted 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 can be provided on the shell 6.

[0108] Referring to Figure 16 As shown, the third aperture 111 and the first aperture 121 on the insulating body 1 are both towards the closed end of the shell 6, and the closed end of the shell 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 second cable 10 and the first cable 20 to pass out, and the mating connector can be electrically connected with the connector from the open end of the shell 6.

[0109] A gap exists between the insulating body 1 close to the open end of the shell 6 and the shell 6 for inserting the mating connector. In order to lock the mating connector on the connector, the shell 6 further comprises a third fastener 64 provided on the inner wall of the shell 6, and the third fastener 64 is matched with the connector.

[0110] 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.

[0111] 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.

[0112] 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, and 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 locking of the docking connector by the third fastener 64, only the end of the third elastic arm 641 located outside the shell 6 needs to be pressed.

[0113] 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, and the third locking member 7 in the final locking position keeps the third fastener 64 locked to the docking connector.

[0114] Referring 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.

[0115] Referring to Figure 21 and Figure 23As shown, in order to improve the stability of the third locking member 7 assembled 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 along the first direction, when the fourth positioning block 66 is clamped in one of the two fourth slot holes 731 away from the open 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 open end of the shell 6, the fourth locking member is in the final locking position.

[0116] Exemplarily, the third slot hole 62 is provided on the third locking member 7, and the third positioning block 120 is provided 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 formed 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.

[0117] Continuing to refer to Figure 23 As shown, in order to facilitate the force applied to the third buckle 64, thereby making the docking connector separate from the connector, the ends of the two third elastic arms 641 away from the connecting rod 642, i.e. the 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 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.

[0118] When the above connector is assembled, first, the injection molded first locking member 5 is 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, at the same time, the injection molded second locking member 4 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 installed 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.
