[0060] refer to Figure 3 As shown, the connector includes an insulating body 1, a first terminal 3, a first sealing ring 8, a second sealing ring 9 and a first locking member 5. The insulating body 1 is provided with a first mounting hole 12 extending in the same direction. Any first mounting hole 12 has a first orifice 121 and a second orifice 122 arranged opposite to each other. A plurality of first terminals 3 are detachably inserted into the first mounting hole 12 from each first orifice 121 in a one-to-one correspondence. A first docking terminal on the docking connector that is adapted to the first terminal 3 can be electrically connected to the first terminal 3 through the second orifice 122. Any first terminal 3 is connected to a first cable 20, and the first cable 20 passes through the insulating body 1 from the first orifice 121. The first sealing ring 8 is fixed to a side of the insulating body 1 close to the first orifice 121 and abuts against the insulating body 1. The first sealing ring 8 is provided with a plurality of first The cables 20 have multiple corresponding through holes 84, the first cable 20 is inserted into the through hole 84 and abuts against the inner wall of the through hole 84, the second sealing ring 9 is sleeved on the outside of the insulating body 1, and the shell of the docking connector can be sleeved on the insulating body 1 and abut against the second sealing ring 9, the first locking member 5 is detachably inserted on the insulating body 1, and the first locking member 5 is provided with avoidance grooves 513 of the same number as the first terminals 3, and the first locking member 5 has a pre-installed position and a final locking position. The avoidance grooves 513 on the first locking member 5 in the pre-installed position are opposite to each first terminal to allow the first terminal 3 to be inserted into the first mounting hole 12 or pulled out of the first mounting hole 12; the avoidance grooves 513 on the first locking member 5 in the final locking position are staggered with each first terminal 3 to lock multiple first terminals 3 at the same time.

[0061] The above-mentioned connector and connector assembly utilize the first locking member 5 to simultaneously lock multiple first terminals 3, thereby simplifying the structure of the connector and the connector assembly, thereby reducing the difficulty of assembling the connector and the connector assembly, and the first locking member 5 having a pre-installed position and a final locking position can be pre-assembled on the insulating body 1 when the first terminal 3 is not inserted into the insulating body 1, thereby preventing the first locking member 5 from being lost; at the same time, the first sealing ring 8 is utilized to seal the first cable 20 and the insulating body 1, and the second sealing ring 9 is utilized to seal the connector and the docking connector, thereby improving the sealing performance of the entire connector assembly, and having good dustproof and waterproof effects, and the first sealing ring 8 can simultaneously seal multiple first terminals 3 and the insulating body 1, thereby further simplifying the difficulty of assembling the connector and the connector assembly.

[0062] refer to Fig.12 As shown, a mounting groove 110 connecting each first mounting hole 12 is opened on one side of the insulating body 1 close to the first orifice 121, and the first sealing ring 8 is embedded in the mounting groove 110 and abuts against the groove wall of the mounting groove 110. The setting of the mounting groove 110 improves the stability of the connection between the first sealing ring 8 and the insulating body 1.

[0063] refer to Fig.24 As shown, in order to improve the sealing performance of the first sealing ring 8, the first sealing ring 8 includes a sealing body 83 and a plurality of first annular protrusions 81 arranged on the outer wall surface of the sealing body 83 at intervals 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. At the same time, a plurality of second annular protrusions 82 are arranged on the hole wall of each through hole 84 at intervals along the length direction of the through hole 84, so as to increase the contact area with the second cable 10 and improve the sealing performance. In this 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 second cable 10.

[0064] refer to Fig.25 As shown, a plurality of third annular protrusions 91 and fourth annular protrusions 92 are respectively arranged on the inner circumferential wall and the outer circumferential wall of the second sealing ring 9 along the length direction of the first mounting hole 12 to increase the contact area between the second sealing ring 9 and the insulating body 1 and the docking connector, thereby improving the sealing performance.

[0065] refer to Figure 1-3As shown, the connector further includes a second terminal 2 and a second locking member 4. A second mounting hole 11 is also provided on the insulating body 1, and the second terminal 2 is detachably inserted into the second mounting hole 11. A second fastener 13 is provided in the second mounting hole 11, and a first fastener 14 is provided in the first mounting hole 12. 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 is also detachably inserted in the insulating body 1, and has a pre-installed position and a final locking position. The second locking member 4 in the pre-installed 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 keeps the second fastener 13 locked to the second terminal 2.

[0066] The above-mentioned 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; and 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 connection stability between the first terminal 3 and the insulating body 1, thereby improving the assembly stability of the entire connector.

[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, the second terminal 2 is a signal terminal for transmitting Ethernet signals, and the second cable 10 connected to the second terminal 2 is a high-speed signal cable, and the first terminal 3 is a low-voltage terminal for transmitting, for example, a low-speed CAN signal, and the first cable 20 connected to the first terminal 3 is a low-voltage cable. In order 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, and the internal space of the second mounting hole 11 is larger than the internal space of the first mounting hole 12.

[0068] It is understandable that, in order to achieve sealing between the second terminal 2 and the insulating body 1 , a sealing member abutting against the insulating body 1 may also be sleeved on the second terminal 2 , which will not be described in detail here.

[0069] refer to Figure 1 and Figure 2 As shown, the second mounting hole 11 and the first mounting hole 12 are both along the first direction ( Figure 1 The second mounting hole 11 and the first mounting hole 12 extend in a third direction ( Figure 1Based on the limitation of the internal space size 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 is switched between the pre-installed position and the final locking position by moving along the first direction, and the first locking member 5 is switched between the pre-installed position and the final locking position by moving along the third direction.

[0070] Exemplarily, the number of the second mounting holes 11 is 1, the number of the first mounting holes 12 is 6, and the 6 first mounting holes 12 are arranged along the second direction ( Figure 1 The first mounting holes 12 in any row include three first mounting holes 12 spaced apart along the third direction, and the number of the first terminals 3 is the same as the number of the first mounting holes 12, which also includes 6. At this time, the first locking member 5 moving along the third direction can lock multiple first terminals 3 at the same time, and the second direction is perpendicular to the first direction and the third direction.

[0071] refer to Figure 5-Figure 7 As shown, the second mounting hole 11 is provided with a third opening 111 and a fourth opening 112 opposite to each other along the first direction, and the third opening 111 is provided on the positive side of the fourth opening 112 along the first direction, and the second terminal 2 can be inserted into the second mounting hole 11 from the third opening 111 and move toward the fourth opening 112. The second docking terminal on the docking connector adapted to the second terminal 2 can be electrically connected to the second terminal 2 through the fourth opening 112, and a first stop surface 151 is provided on the inner wall of the second mounting hole 11 near the fourth opening 112, and the first stop surface 151 can abut against the first abutting surface 211 on the second terminal 2, thereby limiting the second terminal 2 from continuing to move toward the fourth opening 112, so that the second terminal 2 is inserted into the preset position of the second mounting hole 11.

[0072] Specifically, refer to Figure 5 and Fig.12 As shown, two first limit blocks 15 are arranged opposite to each other along the second direction on the inner wall surface of the second mounting hole 11, and the first stop surface 151 is formed on the inner side surface of the first limit block 15 and is arranged to gradually move away from the hole wall of the second mounting hole 11 from the end close to the third hole 111 to the end away from the third hole 111. Correspondingly, the first abutting surface 211 is also arranged inclined.

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

[0074] After the second terminal 2 is inserted into the second mounting hole 11 from the third hole 111, it can squeeze the second fastener 13. The first elastic arm 131 deforms and drives the first clamping block 132 to move toward the hole wall of the second mounting hole 11 until the first clamping block 132 is inserted into the first recess 221. At this time, the first stop surface 151 abuts against the first abutting surface 211, and the second fastener 13 locks the second terminal 2 to prevent the second terminal 2 from moving toward the third hole 111.

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

[0076] More specifically, a first guide surface is provided on the side of the first block 132 facing the third hole 111, and the first guide surface gradually moves away from the hole wall of the second mounting hole 11 from the side close to the third hole 111 to the side away from the third hole 111, so as to reduce the difficulty of the second terminal 2 inserted into the second mounting hole 11 and moving toward the fourth hole 112 to cross the first block 132.

[0077] In this embodiment, in order to reduce the difficulty of inserting the second terminal 2 into the second mounting hole 11, the area of ​​the third opening 111 is larger than the maximum cross-sectional area of ​​the second terminal 2. On this basis, the connector further includes an end cover 30, which is mounted on the insulating body 1 and located on one side of the third opening 111 of the second mounting hole 11. The end cover 30 is provided with a threading hole for the first cable 20 to pass through, and the area of ​​the threading hole is smaller than the area of ​​the third opening 111.

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

[0079] refer to Fig.15As shown, the second terminal 2 includes a front shielding shell 21, an inner conductor, a wire clamp and a rear shielding shell 22. The rear end of the front shielding shell 21 is sleeved on the rear shielding shell 22 and crimped with the rear shielding shell 22. The inner conductor is located in the front shielding shell 21 for electrically connecting the second docking terminal and the second cable 10. 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 configured as a dumbbell. The first recess 221 is an annular groove formed on the rear shielding shell 22, and the annular groove is located outside the front shielding shell 21.

[0080] It is understandable that, in other embodiments, the first recess 221 may be disposed on the first elastic arm 131 , while the first clamping block 132 may be disposed on the second terminal 2 .

[0081] refer to Fig.12 and Fig.15 As shown, in order to prevent the second terminal 2 from being inserted too deeply into the second mounting hole 11, thereby causing damage to the second terminal 2 or the insulating body 1, in this embodiment, the inner side surface of the first limit stopper 15 is further provided with a guide groove 152 extending along the first direction, the side of the guide groove 152 close to the fourth orifice 112 is closed, and the outer wall surface of the second terminal 2 is provided with a guide block 212 that slidably cooperates with the guide groove 152. When the second terminal 2 is in a preset position in the second mounting hole 11, the guide block 212 abuts against the groove wall of the guide groove 152 at one end close to the fourth orifice 112. Specifically, the guide block 212 is provided on the outer wall surface of the large diameter section.

[0082] refer to Fig.14 As shown, the second locking member 4 includes a sleeve portion 41 and an insert portion 42, the sleeve portion 41 is connected to the insert portion 42 and is located outside the insert portion 42, and a clamping space with an opening toward the third opening 111 is formed between the sleeve portion 41 and the insert portion 42, the insert portion 42 is inserted into the second mounting hole 11 from the fourth opening 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 opening 112. Figure 6 and Figure 7As shown, when the second locking member 4 is in the pre-installed position, the second locking member 4 and the second fastener 13 are spaced apart 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 from the third opening 111 to the preset position of the second mounting hole 11; when the second locking member 4 is in the final locking position, the second fastener 13 moves toward the second terminal 2 along the first direction, and the inner side of the plug-in portion 42 abuts against the side of the second fastener 13 facing away from the second terminal 2. Limited by the plug-in portion 42, the second fastener 13 no longer has the ability to deform in the direction of 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 when it is 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 face of the insulating body 1 abuts against the side of the clamping space away from the opening, limiting the second locking member 4 from continuing to move toward the third opening 111.

[0084] Specifically, a step surface 421 is formed on one end of the plug-in portion 42 inserted into the second mounting hole 11. When the second locking member 4 is in the final locking position, the second fastener 13 abuts against the step surface 421 to determine the final locking position of the second locking member 4, thereby further reducing the possibility of the second locking member 4 being over-inserted into the second mounting hole 11.

[0085] At the same time, a second stop surface 422 is also provided on the side of the second locking member 4 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 a second abutting surface 213 cooperating with the second stop surface 422 is formed on the outer wall surface of the second terminal 2. 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 cooperates with the first stop surface 151 and the first abutting surface 211 to further limit the movement of the second terminal 2 toward the fourth hole 112.

[0086] More specifically, two second stop surfaces 422 are relatively arranged on the inner wall of the second locking member 4, and correspondingly, two second abutting surfaces 213 are also arranged. The two second abutting surfaces 213 are also formed between the small diameter section and the large diameter section of the front shielding shell 21, that is, the second abutting surface 213 and the first abutting surface 211 together constitute a conical surface connecting the large diameter section and the small diameter section.

[0087] refer to Figure 5 and Fig. 9As shown, in order to facilitate observation of whether the second locking member 4 is in the pre-installed position or the final locking position, and to improve the stability of the second locking member 4 when assembled on the insulating body 1, a first positioning block 17 is further provided on one of the second locking member 4 and the insulating body 1, and a first slot 43 that is snap-fitted with the first positioning block 17 is provided on the other, and two first slots 43 are arranged at intervals along the first direction. When the first positioning block 17 is limited to one of the two first slots 43 away from the fourth orifice 112, the second locking member 4 is in the pre-installed position, and when the first positioning block 17 is limited to one of the two first slots 43 close to the fourth orifice 112, the second locking member 4 is in the final locking position.

[0088] Exemplarily, the first positioning block 17 is disposed on the insulating body 1, and the first slot 43 is disposed on the second locking member 4. Specifically, the cross section of the first positioning block 17 is configured as an equilateral trapezoid or an equilateral triangle with chamfered corners to reduce the difficulty of the first positioning block 17 entering and exiting the first slot 43.

[0089] refer to Fig.14 As shown, in order to reduce the difficulty of the second locking member 4 being separated from the insulating body 1, a clearance notch 411 is formed on the sleeve portion 41, and the clearance notch 411 extends along the first direction to the end surface of the sleeve portion 41 close to the second terminal 2. When the second locking member 4 is removed, a force is applied to the sleeve portion 41 away from the insulating body 1 along the second direction, so that the first positioning block 17 can be separated from the first slot 43.

[0090] refer to Figure 8 As shown, the first mounting hole 12 has a first orifice 121 and a second orifice 122 that are arranged opposite to each other along a first direction, wherein the first orifice 121 and the third orifice 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 near the second orifice 122 side, and the third stop surface 161 can abut against the third abutting surface 33 on the first terminal 3, thereby limiting the first terminal 3 from continuing to move in the direction of the second orifice 122, so that the first terminal 3 is inserted into the preset position of the first mounting hole 12.

[0091] Specifically, a second annular limit stop block 16 is provided on the side of the first mounting hole 12 near the second orifice 122, and a third stop surface 161 is formed on the side of the second limit stop block 16 facing away from the second orifice 122 and is provided as a conical surface, which gradually expands from one end close to the second orifice 122 to the end away from the second orifice 122, and a conical third abutting surface 33 is formed on the outer wall surface of the first terminal 3. When the third abutting surface 33 abuts against the third stop surface 161, the first terminal 3 is inserted into the preset position of the first mounting hole 12.

[0092] refer to Figure 8 and Fig.17As shown, a second recess 31 is provided on the outer wall surface of the first terminal 3, and the first fastener 14 includes an integrally formed second elastic arm 141 and a second clamping block 142, one end of the second elastic arm 141 close to the first opening 121 is connected to 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 opening 122, and the second clamping block 142 is provided 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 engaged 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 opening 121, it can squeeze the first fastener 14. The second elastic arm 141 deforms and drives the second clamping block 142 to move toward the hole wall direction of the first mounting hole 12 until the second clamping block 142 is inserted 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 with the cooperation of the first fastener 14.

[0094] In this embodiment, a second guide surface is further provided on the side of the second block 142 facing the first opening 121. The second guide surface is gradually inclined from the side close to the first opening 121 toward the center direction of the first mounting hole 12 to reduce the difficulty of the first terminal 3 inserted into the first mounting hole 12 and moving toward the second opening 122 to pass over the second block 142.

[0095] It can be understood that the positions of the second recess 31 and the second block 142 can be interchanged between the second elastic arm 141 and the first terminal 3 .

[0096] The first locking member 5 is inserted into the insulating body 1 in the reverse direction of the third direction from the side away from the second terminal 2. Fig.10 , Fig.11 and Fig.16 As shown, the avoidance groove 513 penetrates the first locking member 5 along the first direction, and a plurality of avoidance 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, a clearance groove 32 is provided on the first terminal 3, and a plurality of clearance grooves 32 on each first terminal 3 are arranged along the third direction.

[0098] Taking the case where two rows of first terminals 3 are symmetrically arranged along the second direction as an example, continue to refer to Fig.16As shown, the first locking member 5 includes a connecting portion 52 and two cantilever portions 51. The two cantilever portions 51 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 groove 513 is arranged on the cantilever portion 51. When the cantilever portion 51 is inserted into the insulating body 1 until the first terminal 3 is in the pre-installed position, each avoidance groove 513 on the cantilever portion 51 corresponds to each first terminal 3 one by one, and does not affect the first terminal 3 from being inserted into the first mounting hole 12 or being separated from the first mounting hole 12. When the cantilever portion 51 continues to be inserted into the insulating body 1 until the first terminal 3 is in the final locking position, each avoidance groove 513 is staggered with each first terminal 3, limiting the first terminal 3 from moving toward the second opening 122.

[0099] refer to Fig.13 As shown, in order to provide guidance for the first terminal 3 when the first terminal 3 is inserted into the insulating body 1, two fixing grooves 18 extending along the third direction are provided on the outer wall of the insulating body 1, and the two fixing grooves 18 are respectively connected to the 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 grooves 18.

[0100] Furthermore, in order to facilitate observation of whether the first locking member 5 is in the pre-installed 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, a second positioning block 514 is also provided on one of the first locking member 5 and the insulating body 1, and a second slot 19 that is snap-fitted with the second positioning block 514 is provided on the other, and two second slots 19 are arranged at intervals along the direction in which the first locking member 5 is inserted into the insulating body 1. When the second positioning block 514 is limited to one of the two second slots 19 away from the second terminal 2, the first locking member 5 is in the pre-installed position, and when the second positioning block 514 is limited to one of the two second slots 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 disposed on the cantilever portion 51 of the first locking member 5, and the two cantilever portions 51 are both provided with a second positioning block 514, and the second slot holes 19 corresponding to the second positioning blocks 514 are respectively disposed on the slot side walls of the two fixing slots 18.

[0102] In order to reduce the difficulty of the second positioning block 514 entering the second slot 19, the second positioning block 514 is designed to be triangular, and the first locking member 5 is also provided with a strip-shaped clearance hole 515 extending along the third direction. When the second positioning block 514 enters the second slot 19, the clearance hole 515 provides an escape space for the deformation of the first locking member 5. Specifically, the cantilever portion 51 also includes an L-shaped mounting portion 512 and a locking portion 511, the mounting portion 512 and the locking portion 511 are both connected to the connecting portion 52, the mounting portion 512 can slide in the fixing groove 18, and the locking portion 511 is inserted into the first mounting hole 12, the second positioning block 514 and the escape groove 513 are respectively arranged on the mounting portion 512 and the locking portion 511, and the clearance hole 515 is also arranged on the mounting portion 512. It can be understood that the arrangement of the clearance 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 , a force application groove 521 for convenient force application is further provided on the connecting portion 52 .

[0104] refer to Figure 3 and Figure 8 As shown, the connector also includes a first sealing ring 8, which is arranged at the second opening 122 of the first mounting hole 12 and has a through hole 84 for the second cable 10 to pass through. The first sealing ring 8 can block the gap between the second opening 122 and the first terminal 3, thereby achieving dustproof and waterproof effects.

[0105] refer to Figure 1-Figure 3 As shown, the connector further includes a shell 6, which is fixedly sleeved outside the insulating body 1 to protect the insulating body 1, and there is a gap between the shell 6 and the insulating body 1 for the insertion of the docking connector. Specifically, the shell 6 has an inner cavity that is open on the opposite side along the first direction, and the insulating body 1 is located in the inner cavity of the shell 6. An operating hole 61 connected to the inner cavity of the shell 6 is provided at a position on the shell 6 corresponding to the connecting portion 52 of the first locking member 5, and a force in the direction of the second terminal 2 can be applied to the first locking member 5 through the operating hole 61, so that the first locking member 5 is switched from the pre-installed position to the final locking position.

[0106] It is worth emphasizing that the size of the operating hole 61 along the second direction is smaller than the length of the connecting portion 52 along the second direction. In other words, the positive projection area of ​​the first locking member 5 in the direction of the operating hole 61 is larger than the area of ​​the operating hole 61, so as to prevent the first locking member 5 from detaching from the insulating body 1 from the operating hole 61 or being squeezed to the final locking position during transportation.

[0107] Specifically, refer to Fig. 9 , Fig. 22 and Fig.23As shown, the shell 6 is provided with a third slot 62, and the insulating body 1 is provided with a third positioning block 120 that is engaged with the third slot 62. The third positioning block 120 is limited in the third slot 62 to realize the detachable fixed connection between the insulating body 1 and the shell 6. More specifically, two third slots 62 are symmetrically provided on the shell 6 along the third direction, and two third positioning blocks 120 are also provided 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 facing away from the slot of the shell 6 to reduce the difficulty of the third positioning block 120 being engaged with the third slot 62. Of course, the third slot 62 can also be provided on the insulating body 1, and the third positioning block 120 is provided on the shell 6.

[0108] refer to Fig.16 As shown, the third opening 111 and the first opening 121 on the insulating body 1 are both facing the closed end of the shell 6, and a plurality of through holes 63 for the first cable 20 and the second cable 10 to pass through are respectively opened at the positions corresponding to the second mounting hole 11 and the first mounting hole 12 at the closed end of the shell 6, and the docking connector can be electrically connected to the connector from the open end of the shell 6.

[0109] There is a gap between the end of the insulating body 1 close to the shell 6 for the butt connector to be inserted. In order to lock the butt connector on the connector, the shell 6 also includes a third fastener 64 arranged on the inner wall of the shell 6, and the third fastener 64 is snap-fitted with the connector.

[0110] Specifically, refer to Fig.19 and Fig. 22 As shown, the third fastener 64 includes a third elastic arm 641 and a third recess 643. The third elastic arm 641 is connected to the inner wall of the shell 6. The third recess 643 is arranged at one end of the third elastic arm 641 extending in the direction of the slot. A third clamping block cooperating with the third recess 643 is formed on the docking connector. The third clamping block can be inserted into the third recess 643 to lock the docking connector.

[0111] More specifically, two third elastic arms 641 are arranged at intervals along the third direction, and the two third elastic arms 641 are connected by a connecting rod 642 to form the 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 .

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

[0113] In order to further improve the stability between the connector and the docking connector, the connector also includes a third locking member 7, which also has a pre-installed position and a final locking position. The third locking member 7 in the pre-installed position allows the docking connector to be inserted into a preset position in the housing 6, and the third locking member 7 in the final locking position keeps the third fastener 64 locked on the docking connector.

[0114] Continue to refer Fig.19 and Fig. 20 As shown, the third locking member 7 is inserted into the housing 6 from the closed end of the housing 6 along the first direction, and the third locking member 7 includes a locking arm 71. The end of the locking arm 71 of the third locking member 7 in the pre-installed position is located on the side of the connecting rod 642 facing away from the open side of the housing 6. The locking arm 71 on the third locking member 7 in the final locking position abuts against the outer side of the third fastener 64, restricting the third fastener 64 from moving to the side away from the third clamping block. Specifically, a locking groove 72 is provided on the locking arm 71, 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] refer to Fig.21 and Fig.23 As shown, in order to improve the stability of the third locking member 7 when assembled on the shell 6, a fourth positioning block 66 is further provided on one of the third locking member 7 and the shell 6, and a fourth slot 731 which is engaged with the fourth positioning block 66 is provided on the other. Two fourth slots 731 are arranged at intervals along the first direction.

[0116] Exemplarily, the third slot 62 is provided on the third locking member 7, and the third positioning block 120 is provided on the housing 6, specifically, on the hole wall of the insertion hole 65. Specifically, the third locking member 7 includes two positioning arms 73 spaced along the third direction and arranged on opposite sides of the locking arm 71, the two positioning arms 73 are both connected to the locking arm 71 and inserted into the insertion hole 65, and the third slot 62 is provided on the positioning arms 73. At the same time, in order to reduce the difficulty of disassembly and assembly of the third locking member 7, the third locking member 7 also includes a push-pull plate 74, which connects the locking arm 71 and the end of the positioning arm 73 located outside the housing 6.

[0117] Continue to refer Fig.23 As shown, in order to facilitate the application of force to the third fastener 64 so as to disengage the docking connector 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 located outside the housing 6, are connected to a U-shaped connecting block 644, and the two third elastic arms 641 are respectively connected to the two ends of the connecting block 644. By applying pressure to the connecting block 644, the third elastic arms 641 can be moved away from the third clamping block under the action of a lever, so that the third elastic arms 641 are separated from the third clamping block. The locking arm 71 of the third locking member 7 passes through the connecting block 644 and is inserted into the housing 6, 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 assembling the above-mentioned connector, first insert the injection-molded first locking member 5 into the insulating body 1 along the third direction so that the first locking member 5 is in the pre-installed position, then sleeve the second sealing ring 9 on the insulating body 1, and at the same time insert the injection-molded second locking member 4 into the second mounting hole 11 along the first direction so that the second locking member 4 is in the pre-installed position, and then install the first sealing ring 8 in the mounting groove 110; then sleeve the housing 6 on the insulating body 1, and insert the third locking member 7 into the housing 6, and finally insert the second terminal 2 and the first terminal 3, and when necessary, push the second locking member 4 and the first locking member 5 to the final locking position.

[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 with the help of a tool, and then the second fastener 13 can be pried toward the hole wall of the second mounting hole 11 with the help of a tool, so that the second terminal 2 can be separated from the insulating body 1, effectively reducing the cost of fault repair; when the first terminal 3 needs to be removed from the first mounting hole 12 to replace a new first terminal 3, a force can be applied to the first locking member 5 along the third direction away from the insulating body 1 through the force application groove 521, so that the first locking member 5 can be removed from the insulating body 1 , and then use a tool to reach into the first mounting hole 12 to apply a force to the first fastener 14 away from the first terminal 3, so that the first fastener 14 is separated from the first terminal 3, and the first terminal 3 can be separated from the insulating body 1; when the docking connector needs to be separated from the connector, pressure is applied to the push-pull plate 74 of the third locking member 7 to disengage the end of the third locking member 7 that is engaged with the third fastener 64 from the third fastener 64, and then the third locking member 7 is pulled out of the housing 6, and pressure is applied to the connecting block 644 of the third fastener 64 to disengage the end of the third fastener 64 that is engaged with the docking connector from the docking connector, and the docking connector can be pulled out of the housing 6.
