[0018] The present invention will be further described below with reference to the drawings and examples. It should be understood that the specific examples described here are merely for the purpose of illustrating the present invention and are not intended to limit the present invention. For the sake of convenience, the drawings show only the parts relevant to the present invention, rather than all of the structures.

[0019] In describing the present invention, unless otherwise clearly specified or limited, the terms "connected," "coupled," and "fixed" should be interpreted broadly, and may refer to, for example, a fixed connection, a detachable connection, an integral molding, a mechanical connection, an electrical connection, a direct connection, an indirect connection via an intermediate medium, an internal communication between two elements, or an interactive relationship between two elements. Those skilled in the art will be able to understand the specific meaning of the above terms in the present invention depending on the specific case.

[0020] In this invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include direct contact between the first and second features, or may include contact between the first and second features via another feature between them rather than direct contact. Furthermore, a first feature being "above," "above," and "on the upper surface" of a second feature may include the first feature being directly above and diagonally above the second feature, or may simply mean that the first feature is higher in horizontal height than the second feature. A first feature being "below," "below," and "on the lower surface" of a second feature may include the first feature being directly below and diagonally below the second feature, or may simply mean that the first feature is lower in horizontal height than the second feature.

[0021] In the description of the present embodiment, the terms "upper," "lower," "left," "right," and other orientations or positional relationships are merely used to facilitate the description and simplify the operation based on the orientations or positional relationships shown in the drawings, and do not indicate or imply that the indicated devices or elements necessarily have a specific orientation or must be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention. Furthermore, the terms "first" and "second" are merely used to distinguish between the two in the description and have no special meaning.

[0022] In an embodiment of the present invention, a connector and a connector assembly are provided, the connector assembly including the connector and a mating connector that is mated with the connector, the connector being connected to one device via a cable and the mating connector being provided on the device body of the other device. The device where the mating connector is located may be, but is not limited to, an in-vehicle processing device such as a domain controller or an IVI, and the connector may be, but is not limited to, an in-vehicle device connected to the in-vehicle processing device such as a laser radar or a gateway.

[0023] 1, 3, 8 and 24, the connector includes an insulating body 1, a first terminal 3, a first seal ring 8 and a second seal ring 9. The insulating body 1 is provided with a plurality of first mounting holes 12 extending in the same direction. The first mounting holes 12 have a first opening 121 and a second opening 122 arranged opposite each other. The plurality of first terminals 3 are inserted into the first mounting holes 12 in one-to-one correspondence through the first openings 121. A first mating terminal corresponding to the first terminal 3 in the mating connector can be electrically connected to the first terminal 3 via the second opening 122. A first cable 20 is also connected to the first terminal 3, and the first cable 20 is inserted through the insulating body 1 from the first hole opening 121. The first seal ring 8 is fixed to the side of the insulating body 1 closer to the first hole opening 121 and abuts against the insulating body 1. The first seal ring 8 has a plurality of through holes 84 that correspond one-to-one to the plurality of first cables 20. The first cable 20 is drilled into the through holes 84 and abuts against the inner wall of the through holes 84. The second seal ring 9 is fitted outside the insulating body 1, and the housing of the mating connector is fitted into the insulating body 1 and can abut against the second seal ring 9.

[0024] The connector and connector assembly described above uses a first seal ring 8 to seal the first cable 20 and the insulating body 1, and a second seal ring 9 to seal the connector and the mating connector, improving the sealing performance of the entire connector assembly and providing good dustproof and waterproof effects. Furthermore, the first seal ring 8 can simultaneously seal the multiple first terminals 3 and the insulating body 1, reducing the difficulty of mounting the connector and connector assembly.

[0025] Referring to Figure 8, an installation groove 110 is provided on the side of the insulating body 1 close to the first hole opening 121, connecting each of the first installation holes 12. The first seal ring 8 is fitted into the installation groove 110 and abuts against the groove wall of the installation groove 110. The installation of the installation groove 110 improves the stability of the connection between the first seal ring 8 and the insulating body 1.

[0026] 24 , in order to improve the sealing performance of the first seal ring 8, the first seal ring 8 includes a seal body 83 and a plurality of first annular protrusions 81 provided at intervals on the outer wall surface of the seal body 83 along the length of the first mounting hole 12, which increases the contact area with the groove side wall of the mounting groove 110 and improves sealing performance. Furthermore, a plurality of second annular protrusions 82 are provided at intervals on the hole wall of each through hole 84 along the length of the through hole 84, which increases the contact area with the first cable 20 and improves sealing performance. In this embodiment, the length direction of the through holes 84 coincides with the length direction of the first mounting hole 12, reducing bending deformation of the first cable 20.

[0027] Referring to Figure 25, a plurality of third annular protrusions 91 and fourth annular protrusions 92 are provided at intervals on the inner and outer peripheral walls of the second seal ring 9 along the longitudinal direction of the first mounting hole 12, thereby increasing the contact area between the second seal ring 9 and the insulating body 1 and the mating connector and improving sealing performance.

[0028] 1 to 3, 6 and 12, the connector further includes 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 manufactured by injection molding. A second mounting hole 11 is further formed in the insulating body 1, the second terminal 2 is 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 in a preset position in the second mounting hole 11, and the first fastener 14 is used to lock the first terminal 3 in a preset position in the first mounting hole 12. The second locking member 4 and the first locking member 5 are removably inserted into the insulating body 1, and both the second locking member 4 and the first locking member 5 have a temporary mounting position and a final locking position, and the second locking member 4 in the temporary mounting 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 maintains the lock of the second terminal 2 by the second fastener 13, and the first locking member 5 in the temporary mounting position allows the first terminal 3 to be inserted into or removed from the first mounting hole 12, and the first locking member 5 in the final locking position can lock the first terminal 3.

[0029] In the above connector, the second terminal 2 is primarily locked using the second fastener 13, and then the second locking member 4 is used to restrict the position of the second fastener 13, maintaining the locking of the second terminal 2 by the second fastener 13 and improving the stability of the connection between the second terminal 2 and the insulating body 1. Meanwhile, the first fastener 14 primarily locks the first terminal 3, and the first locking member 5 secondarily locks the first terminal 3, improving the stability of the connection between the first terminal 3 and the insulating body 1 and thereby improving the assembly stability of the entire connector. Furthermore, the first locking member 5, the second locking member 4, and the insulating body 1 are all injection molded, and the first locking member 5 and the second locking member 4 can be attached to the insulating body 1 in advance and positioned in a temporary attachment position before transportation, reducing the possibility of the first locking member 5 and the second locking member 4 being lost and reducing the difficulty of later assembly.

[0030] In this embodiment, a second cable 10 is connected to the second terminal 2, 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, the second cable 10 connected to the second terminal 2 is a high-speed signal cable, and if the first terminal 3 is, for example, a low-voltage terminal for transmitting low-speed CAN signals, 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 the internal space of the first mounting hole 12.

[0031] It is understood that in order to achieve a seal between the second terminal 2 and the insulating body 1, a sealing member abutted against the insulating body 1 may be fixedly fitted into the second terminal 2, and no further explanation will be given here.

[0032] 1 and 2 , the second mounting holes 11 and the first mounting holes 12 extend along a first direction (the X direction and its reverse direction in FIG. 1 , where the X direction is the forward direction of the first direction and the reverse direction of the X direction is the reverse direction of the first direction), and are spaced apart along a third direction perpendicular to the first direction (the Z direction and its reverse direction in FIG. 1 , where the Z direction is the forward direction of the third direction and the reverse direction of the Z direction is the reverse direction of the third direction). Due to the limited size of the internal space of the second mounting holes 11 and the first mounting holes 12, in order to reduce the difficulty of attaching the second locking member 4 and the first locking member 5 to the insulating body 1, the second locking member 4 is moved along the first direction to switch between the temporary mounting position and the final locking position, and the first locking member 5 is moved along the third direction to switch between the temporary mounting position and the final locking position.

[0033] Illustratively, the number of second mounting holes 11 is one, the number of first mounting holes 12 is six, and the six first mounting holes 12 are arranged in two rows symmetrically along the second direction (the Y direction and its reverse direction in FIG. 1 , where the Y direction is the forward direction of the second direction and the reverse direction of the Y direction is the reverse direction of the second direction), and the first mounting holes 12 in any row include three first mounting holes 12 spaced apart along the third direction, and the number of first terminals 3 is the same as the number of first mounting holes 12, i.e., six. In this case, the first locking member 5 moving along the third direction can simultaneously lock multiple first terminals 3, and the second direction is perpendicular to the first direction and the third direction.

[0034] 5 to 7 , the second mounting hole 11 has a third opening 111 and a fourth opening 112 that face each other along the first direction, and the third opening 111 is located on the same side of the fourth opening 112 as the first opening, so that the second terminal 2 can be inserted into the second mounting hole 11 from the third opening 111 and moved toward the fourth opening 112. A second mating terminal corresponding to the second terminal 2 in the mating connector can be electrically connected to the second terminal 2 via the fourth opening 112, and a first stopper surface 151 is located on the inner wall of the second mounting hole 11 near the fourth opening 112, and the first stopper surface 151 can abut against a first abutment surface 211 of the second terminal 2, restricting continued movement of the second terminal 2 toward the fourth opening 112 and inserting the second terminal 2 into a preset position in the second mounting hole 11.

[0035] 5 and 12, two first position limiting blocks 15 are provided facing each other along the second direction on the inner wall surface of the second mounting hole 11, and the first stopper surface 151 is formed on the inner surface of the first position limiting block 15 and is provided so as to gradually move away from the wall of the second mounting hole 11 from one end closer to the third hole opening 111 to one end farther from the third hole opening 111. Correspondingly, the first abutment surface 211 is also provided at an incline.

[0036] Referring to Figures 6, 7 and 15, a first recess 221 is provided on the outer wall surface of the second terminal 2, and the second fastener 13 has a first elastic arm 131 and a first locking block 132 that are integrally molded, one end of the first elastic arm 131 close to the third hole opening 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 opening 112, and the first locking block 132 is provided on the side of the first elastic arm 131 farther from the hole wall of the second mounting hole 11, and the first locking block 132 engages with the first recess 221.

[0037] After the second terminal 2 is inserted into the second mounting hole 11 through the third hole opening 111, it can press the second fastener 13, causing the first elastic arm 131 to deform and move the first locking block 132 toward the hole wall of the second mounting hole 11. When the first locking block 132 engages into the first recess 221, the first stopper surface 151 abuts against the first abutment surface 211, and the second fastener 13 locks the second terminal 2 and prevents the second terminal 2 from moving toward the third hole opening 111.

[0038] Specifically, two second fasteners 13 are provided symmetrically along the third direction in the second mounting hole 11, improving the stability of locking the second terminal 2 by the second fasteners 13. More specifically, the two second fasteners 13 are provided in two gaps formed by the two first position limiting blocks 15, respectively, and are connected to the first position limiting blocks 15 to increase the structural strength of the second fasteners 13.

[0039] More specifically, a first guide surface is provided on the side of the first locking block 132 facing the third hole opening 111, and the first guide surface gradually moves away from the hole wall of the second mounting hole 11 from the side closer to the third hole opening 111 to the side farther from the third hole opening 111, thereby reducing the difficulty of one end of the second terminal 2 inserted into the second mounting hole 11 climbing over the first locking block 132 when moving toward the fourth hole opening 112.

[0040] In this embodiment, in order to reduce the difficulty in 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. In addition, the connector further includes an end cap 30, which is attached to the insulating body 1 and located on the third opening 111 side of the second mounting hole 11. The end cap 30 has a through hole through which the second cable 10 passes, and the through hole has an area smaller than the area of ​​the third opening 111.

[0041] After inserting the second terminal 2 connected to the second cable 10 into the second mounting hole 11, the end cap 30 is attached to the insulating body 1, thereby reducing the possibility of the second cable 10 shaking and improving the stability of the entire connector. Specifically, the end cap 30 is snap-fit ​​connected to the insulating body 1 to facilitate inspection and replacement of the second terminal 2.

[0042] 15 , the second terminal 2 includes a front shield shell 21, an inner conductor, a clip, and a rear shield shell 22, the rear end of the front shield shell 21 is fitted into and crimped to the rear shield shell 22, the inner conductor is located within the front shield shell 21 and is used to electrically connect the second mating terminal and the second cable 10, and the clip is located within the rear shield shell 22 and is used to fix one end of the second cable 10 within the rear shield shell 22. The front shield shell 21 is provided with a small diameter section and a large diameter section in sequence along the direction opposite to the first direction, the first abutment surface 211 is formed between the large diameter section and the small diameter section, the rear shield shell 22 is set in a dumbbell shape, and the first recess 221 is an annular groove formed in the rear shield shell 22 and is located outside the front shield shell 21.

[0043] It can be understood that in other embodiments, the first recess 221 may be provided on the first elastic arm 131 and the first locking block 132 may be provided on the second terminal 2 .

[0044] 12 and 15, to prevent the second terminal 2 from being inserted too deeply into the second mounting hole 11 and damaging the second terminal 2 or the insulating body 1, in this embodiment, the inner surface of the first position limiting block 15 is further provided with a guide groove 152 extending along the first direction, the side of the guide groove 152 closer to the fourth opening 112 being closed, and the outer wall surface of the second terminal 2 is provided with a guide block 212 that slides into engagement with the guide groove 152, and when the second terminal 2 is in a preset position within the second mounting hole 11, the guide block 212 abuts against the groove wall at one end of the guide groove 152 closer to the fourth opening 112. Specifically, the guide block 212 is provided on the outer wall surface of the large-diameter step.

[0045] Referring to Figure 14, the second locking member 4 has a fitting portion 41 and an insertion portion 42, the fitting portion 41 is connected to the insertion portion 42 and is located outside the insertion portion 42, a clamping space opening toward the third hole opening 111 is formed between the fitting portion 41 and the insertion portion 42, the insertion portion 42 is inserted into the second mounting hole 11 through the fourth hole opening 112, and the fitting portion 41 is fitted to the outside of the insulating body 1, thereby positioning the side wall of the insulating body 1 within the clamping space.

[0046] The second locking member 4 is inserted into the second mounting hole 11 through the fourth opening 112. Referring to FIGS. 6 and 7 , when the second locking member 4 is in the temporary mounting 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, allowing the second terminal 2 to be inserted into the preset position of the second mounting hole 11 through the third opening 111. When the second locking member 4 is in the final locking position, the second fastener 13 moves toward the second terminal 2 in the first direction, and the inner side of the insertion portion 42 abuts against the side of the second fastener 13 facing away from the second terminal 2. Restrained by the insertion portion 42, the second fastener 13 is unable to deform toward the wall of the second mounting hole 11 and is therefore always engaged with the second terminal 2, maintaining stability when the second terminal 2 is inserted into the second mounting hole 11. Furthermore, when the second locking member 4 is in the final locking position, the end face of the insulating body 1 abuts against the side farther from the opening of the clamping space, restricting the second locking member 4 from continuing to move toward the third hole opening 111.

[0047] Specifically, referring to FIG. 14 , a stepped surface 421 is formed at one end of the insertion portion 42 that is inserted into the second mounting hole 11, and when the second locking member 4 is in the final locking position, the second fastener 13 abuts against the stepped surface 421 to confirm the final locking position of the second locking member 4, further reducing the possibility of the second locking member 4 being over-inserted into the second mounting hole 11.

[0048] In addition, a second stopper surface 422 is further provided on the side of the second locking member 4 facing the second terminal 2, and the second stopper surface 422 gradually moves away from the wall of the second mounting hole 11 from one end closer to the third opening 111 to the end farther from the third opening 111, and a second abutment surface 213 that engages with the second stopper surface 422 is formed on the outer wall surface of the second terminal 2. When the second locking member 4 is in the final lock position, the second stopper surface 422 abuts against the second abutment surface 213, and together with the first stopper surface 151 and the first abutment surface 211, further restricts movement of the second terminal 2 in the direction of the fourth opening 112.

[0049] More specifically, two second stopper surfaces 422 are provided facing the inner wall of the second locking member 4, and two second abutment surfaces 213 are provided corresponding to them, and the two second abutment surfaces 213 are similarly formed between the small diameter step and the large diameter step of the front shield shell 21, that is, the second abutment surface 213 and the first abutment surface 211 together form a tapered surface connecting the large diameter step and the small diameter step.

[0050] 5 and 9, in order to easily observe whether the second locking member 4 is in the temporary installation position or the final locking position and to improve stability when attaching the second locking member 4 to 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 engages with the first positioning block 17 is provided on the other. The first slots 43 are provided in pairs and spaced apart in the first direction. When the first positioning block 17 is restricted to a position farther from the fourth opening 112 of the two first slots 43, the second locking member 4 is in the temporary installation position. When the first positioning block 17 is restricted to a position nearer to the fourth opening 112 of the two first slots 43, the second locking member 4 is in the final locking position.

[0051] Illustratively, the first positioning block 17 is provided in the insulating body 1, and the first slot 43 is provided in the second locking member 4. Specifically, to reduce the difficulty of the first positioning block 17 entering and exiting the first slot 43, the cross section of the first positioning block 17 is set to be an equilateral trapezoid or a chamfered equilateral triangle.

[0052] 14 , in order to reduce the difficulty of removing the second locking member 4 from the insulating body 1, a relief notch 411 is formed in the fitting portion 41, and the relief notch 411 extends in the first direction to the end face of the fitting portion 41 that is closer to the second terminal 2. When removing the second locking member 4, applying a force to the fitting portion 41 in the second direction away from the insulating body 1 allows the first positioning block 17 to be removed from the first slot 43.

[0053] Referring to Figure 8, when the first hole 121 and the third hole 111 are located on the same side of the insulating body 1, a third stopper surface 161 is provided on the side of the first mounting hole 12 closer to the second hole 122, and the third stopper surface 161 can abut against the third abutment surface 33 of the first terminal 3, restricting the first terminal 3 from continuing to move toward the second hole 122 and inserting the first terminal 3 into a preset position of the first mounting hole 12.

[0054] Specifically, a ring-shaped second position limiting block 16 is provided on the side closer to the second hole opening 122 of the first mounting hole 12, and a third stopper surface 161 is formed on the side facing away from the second hole opening 122 of the second position limiting block 16 and is set as a tapered surface, gradually expanding from one end closer to the second hole opening 122 to one end farther from the second hole opening 122, and a tapered third abutment surface 33 is formed on the outer wall surface of the first terminal 3, and when the third abutment surface 33 is abutted against the third stopper surface 161, the first terminal 3 is inserted into a preset position of the first mounting hole 12.

[0055] 8 and 17, a second recess 31 is provided on the outer wall surface of the first terminal 3, and the first fastener 14 includes an integrally molded second resilient arm 141 and a second locking block 142, one end of the second resilient arm 141 close to the first opening 121 is connected to the wall of the first mounting hole 12, and the other end gradually moves away from the wall of the first mounting hole 12 in the direction of the second opening 122, and the second locking block 142 is provided on the side of the second resilient arm 141 farther from the wall of the first mounting hole 12, and the second locking block 142 engages with the second recess 31. Specifically, the second recess 31 is a groove opened in the outer wall surface of the first terminal 3.

[0056] After the first terminal 3 is inserted into the first mounting hole 12 through the first hole opening 121, it can press the first fastener 14, causing the second elastic arm 141 to deform and move the second locking block 142 toward the hole wall of the first mounting hole 12. When the second locking block 142 engages into the second recess 31, the third stopper surface 161 abuts against the third abutment surface 33, and the first terminal 3 is locked by the engagement of the first fastener 14.

[0057] In this embodiment, a second guide surface is further provided on the side of the second locking block 142 facing the first hole opening 121, and the second guide surface gradually inclines from the side closer to the first hole opening 121 toward the center of the first mounting hole 12, thereby reducing the difficulty of one end of the first terminal 3 inserted into the first mounting hole 12 climbing over the second locking block 142 when moving toward the second hole opening 122.

[0058] It can be understood that the positions of the second recess 31 and the second locking block 142 may be interchangeable between the second resilient arm 141 and the first terminal 3 .

[0059] The first locking member 5 is inserted into the insulating body 1 in the direction opposite to the third direction from the side farthest from the second terminal 2. Referring to Figures 10, 11 and 16, the first locking member 5 has an escape groove 513 drilled along the first direction, and the escape groove 513 of the first locking member 5 in the temporary attachment position faces the first terminal 3 and allows the first terminal 3 to be inserted into or removed from the first attachment hole 12. The escape groove 513 of the first locking member 5 in the final lock position is misaligned with the first terminal 3 and locks the first terminal 3 in the first attachment hole 12.

[0060] In order to avoid the first locking member 5 when it moves in the third direction, the first terminal 3 is provided with an escape groove 32. Based on the premise that the first terminals 3 are arranged in a row along the third direction, the escape grooves 32 located on each first terminal 3 are arranged along the third direction, and the first locking member 5 is provided with escape grooves 513 the number of which is the same as the number of first terminals 3.

[0061] Taking an example in which the first terminals 3 are arranged in two symmetrical rows spaced apart along the second direction, and still referring to FIG. 16 , the first locking member 5 has a connecting portion 52 and two cantilever portions 51, the connecting portion 52 extends along the second direction, and the two cantilever portions 51 are respectively provided on opposite sides of the connecting portion 52 along the second direction and perpendicular to the connecting portion 52, making the first locking member 5 approximately U-shaped. The escape grooves 513 are provided in the cantilever portion 51, and when the cantilever portion 51 is inserted into the insulating body 1 until the first terminals 3 are in the temporary mounting position, each escape groove 513 in the cantilever portion 51 corresponds one-to-one with each first terminal 3 and does not affect the insertion of the first terminals 3 into or removal from the first mounting holes 12, and when the cantilever portion 51 continues to be inserted into the insulating body 1 until the first terminals 3 are in the final locking position, each escape groove 513 misaligns with each first terminal 3 and restricts the movement of the first terminals 3 in the direction of the second hole opening 122.

[0062] Referring to Figure 13, in order to provide a guide 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.

[0063] Furthermore, in order to easily observe whether the first locking member 5 is in the temporary installation position or the final locking position and to improve stability when attaching the first locking member 5 to the insulating body 1, a second positioning block 514 is further provided on one of the first locking member 5 and the insulating body 1, and a second groove 19 that engages with the second positioning block 514 is provided on the other, and two second grooves 19 are provided at intervals along the third direction, and when the second positioning block 514 is positioned at the one of the two second grooves 19 that is farther from the second terminal 2, the first locking member 5 is in the temporary installation position, and when the second positioning block 514 is positioned at the one of the two second grooves 19 that is closer to the second terminal 2, the first locking member 5 is in the final locking position.

[0064] For example, the second positioning block 514 is provided on the cantilever portion 51 of the first locking member 5, and the second positioning block 514 is provided on each of the two cantilever portions 51, and the second groove holes 19 corresponding to the second positioning blocks 514 are provided on the groove side walls of the two fixing grooves 18, respectively.

[0065] To reduce the difficulty of inserting the second positioning block 514 into the second slot 19, the first locking member 5 is further provided with an elongated relief hole 515 extending along the third direction. When the second positioning block 514 enters the second slot 19, the relief hole 515 provides relief space for deformation of the first locking member 5. Specifically, the cantilever portion 51 further 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 within the fixing slot 18. The locking portion 511 is inserted into the first mounting hole 12. The second positioning block 514 and the relief groove 513 are provided in the mounting portion 512 and the locking portion 511, respectively. The relief hole 515 is also provided in the mounting portion 512. It can be seen that the provision of the relief hole 515 reduces the cost of materials used to manufacture the first locking member 5.

[0066] More specifically, in order to reduce the difficulty of removing the first locking member 5, the connecting portion 52 is further provided with a biasing groove 521 for facilitating biasing.

[0067] Referring to Figures 3 and 8, the connector further includes a first sealing ring 8, which is disposed at the second opening 122 of the first mounting hole 12 and has a through hole 84 through which the first cable 20 passes. The first sealing ring 8 closes the gap between the second opening 122 and the first terminal 3, thereby providing dustproof and waterproof effects.

[0068] 1 to 3, the connector further includes a housing 6. The housing 6 is fixedly fitted onto the outside of the insulating body 1 and is used to protect the insulating body 1. A gap is provided between the housing 6 and the insulating body 1 for inserting a mating connector. Specifically, the housing 6 has an inner cavity that is open on one side along the direction opposite to the first direction, and the insulating body 1 is located within the inner cavity of the housing 6. An operation hole 61 that communicates with the inner cavity of the housing 6 is provided in the housing 6 at a position corresponding to the connecting portion 52 of the first locking member 5. By applying a force to the first locking member 5 through the operation hole 61 in the direction of the second terminal 2, the first locking member 5 can be switched from the temporary attachment position to the final locking position.

[0069] Furthermore, the length 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 orthogonal 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, which prevents the first locking member 5 from detaching from the insulating body 1 or being pressed to the final locking position through the operating hole 61 during transportation.

[0070] 9, 22, and 23, a third slot 62 is provided in the housing 6, and a third positioning block 120 is provided in the insulating body 1 to engage with the third slot 62. The third positioning block 120 is positioned within the third slot 62, thereby realizing a detachable and fixed connection between the insulating body 1 and the housing 6. More specifically, two third slots 62 are provided symmetrically in the third direction in the housing 6, and two third positioning blocks 120 are also provided. This improves the stability of the connection between the housing 6 and the insulating body 1, and a third guide surface is formed on one end of the third positioning block 120 facing away from the slot in the housing 6, making it easier for the third positioning block 120 to fit into the third slot 62. Of course, the third slot 62 may be provided in the insulating body 1, and the third positioning block 120 may be provided in the housing 6.

[0071] Referring to Figure 16, the third hole opening 111 and the first hole opening 121 in the insulating body 1 both have one end closed toward the housing 6, and at positions corresponding to the second mounting hole 11 and the first mounting hole 12 at the closed end of the housing 6, a plurality of insertion holes 63 through which the second cable 10 and the first cable 20 are inserted are respectively opened, and the mating connector can be electrically connected to the connector from the open end of the housing 6.

[0072] A gap into which a mating connector is inserted is provided between the housing 6 and one end of the insulating body 1 that is close to the opening of the housing 6. To lock the mating connector to the connector, the housing 6 further includes a third fastener 64 provided on the inner wall of the housing 6, and the third fastener 64 engages with the connector.

[0073] Specifically, referring to Figures 19 and 22, the third fastener 64 has 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, the third recess 643 is provided at one end of the third elastic arm 641 extending toward the groove opening, and a third locking block that engages with the third recess 643 is formed on the mating connector, and the third locking block can be engaged with the third recess 643 to lock the mating connector.

[0074] More specifically, two third elastic arms 641 are provided at intervals along the third direction, and the two third elastic arms 641 are connected via a link 642, forming the above-mentioned third recess 643 between the two third elastic arms 641, and the third locking block engages with the third recess 643 and abuts against the link 642.

[0075] 19 and 23, an insertion hole 65 is formed at one closed end of the housing 6, through which the third fastener 64 enters the inner cavity of the housing 6. The insertion hole 65 communicates with the inner cavity of the housing 6. The third elastic arm 641 is connected to the wall of the insertion hole 65 by one fulcrum, and one end of the third elastic arm 641 connected to the link 642 enters the inner cavity of the housing 6 from the insertion hole 65, and the other end is located outside the housing 6. To release the lock of the mating connector by the third fastener 64, the end of the third elastic arm 641 located outside the housing 6 is simply pressed.

[0076] In order to further improve the stability between the connector and the mating connector, the connector further includes a third locking member 7, which similarly has a temporary attachment position and a final locking position, and the third locking member 7 in the temporary attachment position allows the mating connector to be inserted into a preset position within the housing 6, and the third locking member 7 in the final locking position maintains the locking of the mating connector by the third fastener 64.

[0077] 19 and 20 , the third locking member 7 is inserted into the housing 6 from the closed end of the housing 6 in the first direction, and the third locking member 7 has a locking arm 71. When the third locking member 7 is in the temporary installation position, the end of the locking arm 71 is located on the side of the link 642 facing away from the open mouth of the housing 6, and when the third locking member 7 is in the final locking position, the locking arm 71 abuts against the outside of the third fastener 64, restricting the third fastener 64 from moving away from the third locking block. Specifically, the locking arm 71 is provided with a locking groove 72, and the link 642 is fitted in the locking groove 72 and can abut against the bottom of the locking groove 72.

[0078] Referring to Figures 21 and 23, in order to improve the stability of attaching the third locking member 7 to the housing 6, a fourth positioning block 66 is further provided on one of the third locking member 7 and the housing 6, and a fourth groove 731 that engages with the fourth positioning block 66 is provided on the other, and two fourth grooves 731 are provided at intervals along the first direction, and when the fourth positioning block 66 is engaged with the one of the two fourth grooves 731 that is farther from the open end of the housing 6, the fourth locking member is in a temporary attachment position, and when the fourth positioning block 66 is engaged with the one of the two fourth grooves 731 that is closer to the open end of the housing 6, the fourth locking member is in a final locking position.

[0079] For example, the third slot 62 is provided in the third locking member 7, and the third positioning block 120 is provided in 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 apart along the third direction and provided on opposite sides of the locking arm 71, and 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 opened in the positioning arm 73. In addition, to reduce the difficulty of removing the third locking member 7, the third locking member 7 further includes a push-pull plate 74 that connects the locking arm 71 with an end of the positioning arm 73 located outside the housing 6.

[0080] 23 , in order to easily detach the mating connector from the connector by biasing the third fastener 64, a U-shaped connection block 644 is connected to one end of each of the two third elastic arms 641 far from the link 642, i.e., one end of each of the two third elastic arms 641 located outside the housing 6, and the two third elastic arms 641 are respectively connected to both ends of the connection block 644. By applying pressure to the connection block 644, the third elastic arms 641 are moved in a direction away from the third locking block by leverage, thereby separating the third elastic arms 641 and the third locking block. Meanwhile, the locking arm 71 of the third locking member 7 is inserted into the housing 6 after passing through the connection 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.

[0081] When mounting the connector, the injection-molded first locking member 5 is inserted into the insulating body 1 in the third direction and positioned in a temporary mounting position; the second seal ring 9 is fitted into the insulating body 1; the injection-molded second locking member 4 is inserted into the second mounting hole 11 in the first direction and positioned in a temporary mounting position; the first seal ring 8 is mounted in the mounting groove 110; the housing 6 is then fitted into the insulating body 1; the third locking member 7 is inserted into the housing 6; finally, the second terminal 2 and the first terminal 3 are inserted; and, if necessary, the second locking member 4 and the first locking member 5 are pushed into their final locking positions.

[0082] When it is necessary to remove the second terminal 2 from the second mounting hole 11 and replace it with a new second terminal 2, first, the second locking member 4 is removed from the insulating body 1 using a tool, and then the tool is inserted into the second mounting hole 11 and the second fastener 13 is pried toward the hole wall of the second mounting hole 11, thereby separating the second terminal 2 from the insulating body 1, effectively reducing the repair costs. When it is necessary to remove the first terminal 3 from the first mounting hole 12 and replace it with a new first terminal 3, a force is applied to the first locking member 5 via the biasing groove 521 in the third direction away from the insulating body 1, and the first locking member 5 is removed from the insulating body 1, and then the first fastener is inserted into the second mounting hole 11 using a tool. By entering the mounting hole 12 and applying a force to the first fastener 14 to move it away from the first terminal 3, the first terminal 3 can be removed from the insulating body 1. If it is necessary to separate the connector from the mating connector, pressure is applied to the push / pull plate 74 of the third locking member 7 to remove one end of the third locking member 7 that engages with the third fastener 64 from the third fastener 64, and then the third locking member 7 is pulled out of the housing 6. Furthermore, pressure is applied to the connection block 644 of the third fastener 64 to remove one end of the third fastener 64 that engages with the mating connector from the mating connector, allowing the mating connector to be pulled out of the housing 6.
