This is merely for the convenience of explanation and simplification of work, and does not indicate or imply that the mentioned devices or elements must necessarily have a specific direction or be configured and operated in a specific direction; therefore, it should not be understood as a limitation on the present invention. Furthermore, the terms "first" and "second" are used merely for distinction in the description and have no special meaning.

[0022] In an embodiment of the present invention, a connector and a connector assembly are provided, wherein the connector assembly includes the connector and a mating connector that is fitted together with the connector, wherein the connector is connected to one facility via a cable, and the mating connector is installed on the main body of another facility. The facility having the mating connector may be, but is not limited to, on-board processing facilities such as a domain controller or an IVI, and the connector may be, but is not limited to, on-board facilities such as a laser radar or a gateway.

[0023] Referring to FIG. 3, the connector comprises an insulating body (1), a first terminal (3), a first sealing ring (8) and a second sealing ring (9) and a first locking member (5). A first mounting hole (12) extending in the same direction is opened in the insulating body (1). A first hole opening (121) and a second hole opening (122) are installed oppositely in any first mounting hole (12). A plurality of first terminals (3) are each detachably inserted into the first mounting hole (12) from the first hole opening (121) in a corresponding manner. A first counterpart terminal of a mating connector that matches the first terminal (3) can be electrically connected to the first terminal (3) through the second hole opening (122). A first cable (20) is connected to all of the first terminals (3), and the first cable (20) passes through the insulating body (1) from the first hole opening (121). A first sealing ring (8) is fixed to one side near the first hole opening (121) of the insulating body (1) and comes into contact with the insulating body (1). A plurality of through holes (84) corresponding to each of the plurality of first cables (20) are opened in the first sealing ring (8). The first cable (20) passes through the through holes (84) and comes into contact with the inner wall of the through holes (84). A second sealing ring (9) is sleeved on the outside of the insulating body (1), and the housing of the mating connector is sleeved on the insulating body (1) and can come into contact with the second sealing ring (9). The first locking member (5) is detachably inserted and installed in the insulating body (1), and the first locking member (5) is provided with the same number of avoidance grooves (513) as the first terminal (3), and the first locking member (5) has a preliminary mounting position and a final locking position, and the avoidance grooves (513) of the first locking member (5) in the preliminary mounting position are opposite to each first terminal (3) to allow the first terminal (3) to be inserted into the first mounting hole (12) or removed from the first mounting hole (12); and the avoidance grooves (513) of the first locking member (5) in the final locking position are arranged offset from the first terminal (3) to lock a plurality of first terminals (3) simultaneously.

[0024] The above connector and connector assembly simultaneously lock multiple first terminals (3) using a first locking member (5), thereby simplifying the structure of the connector and connector assembly and reducing the difficulty of mounting the connector and connector assembly. The first locking member (5), which has a preliminary mounting position and a final locking position, can be mounted in advance on the insulating body (1) before the first terminal (3) is inserted and installed in the insulating body (1), thus preventing the loss of the first locking member (5); additionally, by sealing the first cable (20) and the insulating body (1) using a first sealing ring (8) and sealing the connector and the mating connector using a second sealing ring (9), the sealing performance of the entire connector assembly is improved, resulting in excellent dustproof and waterproof effects. Furthermore, the first sealing ring (8) can simultaneously seal multiple first terminals (3) and the insulating body (1), thereby further simplifying the difficulty of mounting the connector and connector assembly.

[0025] Referring to FIG. 12, a mounting groove (110) is installed on one side near the first hole opening (121) of the insulating body (1) to connect each first mounting hole (12), and a first sealing ring (8) is inserted into the mounting groove (110) and comes into contact with the groove wall of the mounting groove (110), thereby improving the connection stability between the first sealing ring (8) and the insulating body (1).

[0026] Referring to FIG. 24, in order to improve the sealing performance of the first sealing ring (8), the first sealing ring (8) includes a plurality of first annular protrusions (81) installed at intervals on the outer wall surface of the sealing body (83) along the longitudinal direction of the sealing body (83) and the first mounting hole (12), thereby increasing the contact area with the groove side wall of the mounting groove (110) to improve the sealing performance. Additionally, a plurality of second annular protrusions (82) are installed at intervals along the longitudinal direction of the through hole (84) on the hole wall of each through hole (84) to increase the contact area with the first cable (20) to improve the sealing performance. In this embodiment, the longitudinal direction of the through hole (84) coincides with the longitudinal direction of the first mounting hole (12), thereby reducing the bending deformation of the first cable (20).

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

[0028] Referring to FIGS. 1 to 3, the connector further includes a second terminal (2) and a second locking member (4). A second mounting hole (11) is further opened in the insulating body (1), and the second terminal (2) is detachably inserted and installed within the second mounting hole (11). A second fastener (13) is installed within the second mounting hole (11), and a first fastener (14) is installed within the first mounting hole (12). The second fastener (13) is used to lock the second terminal (2) to a preset position in the second mounting hole (11), and the first fastener (14) is used to lock the first terminal (3) to a preset position in the first mounting hole (12). The second locking member (4) is similarly installed to be detachably inserted into the insulating body (1) and has a preliminary mounting position and a final locking position. The second locking member (4) in the preliminary 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 allows the second fastener (13) to maintain locking to the second terminal (2).

[0029] The above connector performs primary locking on the second terminal (2) using the second fastener (13), and then positions the second fastener (13) using the second locking member (4) so ​​that the second fastener (13) maintains the locking on the second terminal (2), thereby improving the connection stability between the second terminal (2) and the insulating body (1); the first fastener (14) performs primary locking on the first terminal (3), and the first locking member (5) performs secondary locking on the first terminal (3), thereby improving the connection stability between the first terminal (3) and the insulating body (1) and improving the assembly stability of the entire connector.

[0030] In this embodiment, a second cable (10) is connected to the second terminal (2), and the functions of the second terminal (2) and the first terminal (3) are different. For example, if the second terminal (2) is a signal terminal used to transmit 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 a low-voltage terminal used to transmit low-speed CAN signals, for example, 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, and the internal space of the second mounting hole (11) is larger than the internal space of the first mounting hole (12).

[0031] It should be understood that, in order to achieve a seal between the second terminal (2) and the insulating body (1), a sealing member in contact with the insulating body (1) may also be sleeved on the second terminal (2), which is not explained in more detail here.

[0032] Referring to FIGS. 1 and 2, the second mounting hole (11) and the first mounting hole (12) are each extended along the 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 the second mounting hole (11) and the first mounting hole (12) are installed at a distance along the 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). Based on the size limitation of the internal space of the second mounting hole (11) and the first mounting hole (12), in order to reduce the difficulty of mounting the second locking member (4) and the first locking member (5) to the insulating body (1), the second locking member (4) moves along the first direction to implement a transition between the preliminary mounting position and the final locking position, and the first locking member (5) moves along the third direction to implement a transition between the preliminary mounting position and the final locking position.

[0033] For example, the number of second mounting holes (11) is 1, and the number of first mounting holes (12) is 6. The 6 first mounting holes (12) are 2 rows installed symmetrically along the second direction (the Y direction and the reverse direction of 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). The first mounting holes (12) in any row include 3 first mounting holes (12) installed spaced apart along the third direction, and the number of first terminals (3) is the same as the number of first mounting holes (12) and includes 6. At this time, the first locking member (5) moving along the third direction can lock multiple first terminals (3) simultaneously, and the second direction is perpendicular to the first direction and the third direction.

[0034] Referring to FIGS. 5 to 7, a third hole opening (111) and a fourth hole opening (112) are installed facing each other along a first direction in the second mounting hole (11), and the third hole opening (111) is installed on one side of the fourth hole opening (112) along the first direction of the fourth hole opening (112), and the second terminal (2) can be inserted into the second mounting hole (11) from the third hole opening (111) and move toward the fourth hole opening (112). A second counterpart terminal on a mating connector that matches the second terminal (2) can be electrically connected to the second terminal (2) through a fourth hole opening (112), and a first stopper surface (151) is installed on one side of the inner wall of the second mounting hole (11) near the fourth hole opening (112), and the first stopper surface (151) can come into contact with the first contact surface (211) of the second terminal (2), thereby restricting the second terminal (2) from moving in the direction of the fourth hole opening (112) so that the second terminal (2) is inserted into a preset position of the second mounting hole (11).

[0035] Specifically, referring to FIG. 5 and FIG. 12, two first position limiting blocks (15) are installed facing each other along the second direction on the inner wall surface of the second mounting hole (11), and a first stopper surface (151) is formed on the inner surface of the first position limiting block (15), and is installed so as to gradually move away from the hole wall of the second mounting hole (11) from one end close to the third hole opening (111) toward one end moving away from the third hole opening (111). Correspondingly, a first contact surface (211) is also installed at an angle.

[0036] Referring to FIGS. 6 and 7, a first concave portion (221) is installed on the outer wall surface of the second terminal (2), and the second fastener (13) includes a first elastic arm (131) formed by integral molding and a first locking block (132), one end of the first elastic arm (131) near 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) toward the direction of the fourth hole opening (112), and the first locking block (132) is installed on one side of the first elastic arm (131) away from the hole wall of the second mounting hole (11), and the first locking block (132) is locked and coupled with the first concave portion (221).

[0037] After the second terminal (2) is inserted into the second mounting hole (11) from the third hole opening (111), the second fastener (13) can be pressed, and the first elastic arm (131) is deformed so that the first locking block (132) is inserted into the first concave portion (221), and the first locking block (132) is moved toward the hole wall of the second mounting hole (11). At this time, the first stopper surface (151) contacts the first contact surface (211), and the second fastener (13) locks the second terminal (2) to prevent the second terminal (2) from moving toward the third hole opening (111).

[0038] Specifically, two second fasteners (13) are installed symmetrically along the third direction within the second mounting hole (11) to improve the locking stability of the second fasteners (13) with respect to the second terminal (2). More specifically, two second fasteners (13) are each installed within two gaps formed by two first position limiting blocks (15) and connected to the first position limiting blocks (15) to improve the structural strength of the second fasteners (13).

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

[0040] In this embodiment, to reduce the difficulty of inserting the second terminal (2) into the second mounting hole (11), the area of ​​the third hole opening (111) is larger than the maximum cross-sectional area of ​​the second terminal (2). Based on this, the connector further includes an end cover (30) mounted on the insulating body (1) and located on one side of the third hole opening (111) of the second mounting hole (11), and the end cover (30) is provided with a cable penetration hole through which the second cable (10) passes, and the area of ​​the cable penetration hole is smaller than the area of ​​the third hole opening (111).

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

[0042] Referring to FIG. 15, the second terminal (2) includes a front shield shell (21), an inner conductor, a cable clip, and a rear shield shell (22). The rear end of the front shield shell (21) is covered and connected to the rear shield shell (22) and is crimped and coupled with the rear shield shell (22). The inner conductor is located within the front shield shell (21) and is used to electrically connect the second terminal and the second cable (10), and the cable clip is located within the rear shield shell (22) and is used to secure one end of the second cable (10) within the rear shield shell (22). The front shield shell (21) has a small diameter section and a large diameter section installed sequentially along the reverse direction of the first direction, and the first contact surface (211) is formed between the large diameter section and the small diameter section, and the rear shield shell (22) is installed in a dumbbell shape, and the first concave portion (221) is an annular groove formed in the rear shield shell (22), and the annular groove is located on the outside of the front shield shell (21).

[0043] In other embodiments, it can be understood that the first concave portion (221) may be installed on the first elastic rock (131) and the first locking block (132) may be installed on the second terminal (2).

[0044] Referring to FIGS. 12 and 15, in order to prevent the second terminal (2) from being inserted too deeply into the second mounting hole (11) and thereby damaging the second terminal (2) or the insulating body (1), in this embodiment, a guide groove (152) extending along a first direction is further installed on the inner side of the first position limiting block (15), and one side of the guide groove (152) near the fourth hole opening (112) is closed, and a guide block (212) that slides and is coupled with the guide groove (152) is installed on the outer wall of the second terminal (2), and when the second terminal (2) is in a preset position within the second mounting hole (11), the guide block (212) comes into contact with the groove wall of one end near the fourth hole opening (112) of the guide groove (152). Specifically, the guide block (212) is installed on the outer wall of the large diameter section.

[0045] Referring to FIG. 14, the second locking member (4) includes a covering connection part (41) and an insertion connection part (42), the covering connection part (41) is connected to the insertion connection part (42) and is located outside the insertion connection part (42), and a narrow space is formed between the covering connection part (41) and the insertion connection part (42) that is opened toward the direction of the third hole opening (111), and the insertion connection part (42) is inserted into the second mounting hole (11) from the fourth hole opening (112), and the covering connection part (41) is covered and connected to the outside of the insulating body (1) so that the side wall of the insulating body (1) is interposed in the narrow space.

[0046] The second locking member (4) is inserted into the second mounting hole (11) from the fourth hole opening (112). Referring to FIGS. 6 and 7, when the second locking member (4) is in a preliminary mounting position, the second locking member (4) and the second fastener (13) are installed spaced apart along the first direction, and since the second locking member (4) does not interfere with the deformation of the second fastener (13), the second terminal (2) can be inserted from the third hole opening (111) to a preset position in the second mounting hole (11); When the second locking member (4) is in the final locked position, the second fastener (13) moves toward the second terminal (2) along the first direction, and the inner side of the insertion connection part (42) contacts the side facing away from the second terminal (2) of the second fastener (13), and is restricted by the insertion connection part (42), so that the second fastener (13) can no longer be deformed toward the hole wall of the second mounting hole (11) and is always caught on the second terminal (2), thereby maintaining stability when the second terminal (2) is inserted into the second mounting hole (11). It should be emphasized that when the second locking member (4) is in the final locked position, the cross-section of the insulating body (1) contacts the side facing away from the opening of the narrow space, thereby restricting the second locking member (4) from continuing to move toward the third hole opening (111).

[0047] Specifically, a stepped surface (421) is formed on one end that is inserted into the second mounting hole (11) of the insertion connection part (42), and when the second locking member (4) is in the final locked position, the second fastener (13) comes into contact with the stepped surface (421), thereby confirming the final locked position of the second locking member (4) and further reducing the possibility that the second locking member (4) is excessively inserted into the second mounting hole (11).

[0048] Additionally, a second stopper surface (422) is further installed on one side facing the second terminal (2) of the second locking member (4), and the second stopper surface (422) gradually moves away from the hole wall of the second mounting hole (11) from one end close to the third hole opening (111) toward one end moving away from the third hole opening (111), and a second contact surface (213) that is coupled 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 locked position, the second stopper surface (422) contacts the second contact surface (213) and, in cooperation with the first stopper surface (151) and the first contact surface (211), further restricts the movement of the second terminal (2) toward the fourth hole opening (112).

[0049] More specifically, two second stopper surfaces (422) are installed facing the inner wall of the second locking member (4), and two second contact surfaces (213) are installed correspondingly, and the two second contact surfaces (213) are likewise formed between the small diameter section and the large diameter section of the front shield shell (21), that is, the second contact surfaces (213) and the first contact surfaces (211) together form a single conical surface connecting the large diameter section and the small diameter section.

[0050] Referring to FIGS. 5 and 9, in order to easily observe whether the second locking member (4) is in a preliminary mounting position or a final locking position and to improve stability when mounting the second locking member (4) to the insulating body (1), a first positioning block (17) is further installed on one of the second locking member (4) and the insulating body (1), and a first slit hole (43) that engages with the first positioning block (17) is installed on the other. Two first slit holes (43) are installed spaced apart along a first direction. When the first positioning block (17) is positioned by one of the two first slit holes (43) that is further away from the fourth hole opening (112), the second locking member (4) is in a preliminary mounting position and the first positioning block (17) is positioned by one of the two first slit holes (43) that is closer to the fourth hole opening (112). When positioning is limited, the second locking member (4) is in the final locked position.

[0051] For example, the first positioning block (17) is installed in the insulating body (1), and the first slit hole (43) is installed in the second locking member (4). Specifically, to reduce the difficulty of the first positioning block (17) entering and exiting the first slit hole (43), the cross-section of the first positioning block (17) is installed as an isosceles trapezoid or an equilateral triangle with chamfered corners.

[0052] Referring to FIG. 14, to reduce the difficulty of the second locking member (4) being detached from the insulating body (1), an avoidance notch (411) is formed in the covering connection part (41), and the avoidance notch (411) extends along the first direction to a cross section close to the second terminal (2) of the covering connection part (41). When the second locking member (4) is detached, if a force is applied to the covering connection part (41) moving away from the insulating body (1) along the second direction, the first positioning block (17) can be detached from the first slit hole (43).

[0053] Referring to FIG. 8, the first mounting hole (12) is provided with a first hole opening (121) and a second hole opening (122) that are installed in a large manner along the first direction, and the first hole opening (121) and the third hole opening (111) are located on the same side of the insulating body (1), and a third stopper surface (161) is installed on one side close to the second hole opening (122) of the first mounting hole (12), and the third stopper surface (161) can come into contact with the third contact surface (33) of the first terminal (3), thereby restricting the first terminal (3) from continuing to move toward the direction of the second hole opening (122) so that the first terminal (3) is inserted into a preset position of the first mounting hole (12).

[0054] Specifically, an annular second position limiting block (16) is installed on one side close to the second hole opening (122) of the first mounting hole (12), and a third stopper surface (161) is formed on one side of the second position limiting block (16) facing away from the second hole opening (122) and is installed as a conical surface, which gradually expands from one end close to the second hole opening (122) toward one end away from the second hole opening (122), and a conical third contact surface (33) is formed on the outer wall surface of the first terminal (3), and when the third contact surface (33) comes into contact with the third stopper surface (161), the first terminal (3) is inserted into a preset position of the first mounting hole (12).

[0055] Referring to FIGS. 8 and FIGS. 17, a second concave portion (31) is installed on the outer wall surface of the first terminal (3), and the first fastener (14) includes a second elastic arm (141) formed by integral molding and a second locking block (142). One end of the second elastic arm (141) near the first hole 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) toward the direction of the second hole opening (122). The second locking block (142) is installed on one side of the second elastic arm (141) moving away from the hole wall of the first mounting hole (12), and the second locking block (142) is engaged with the second concave portion (31). Specifically, the second concave portion (31) is a groove formed on the outer wall surface of the first terminal (3).

[0056] After the first terminal (3) is inserted into the first mounting hole (12) from the first hole opening (121), the first fastener (14) can be pressed, and the second elastic arm (141) is deformed so that the second locking block (142) is inserted into the second concave portion (31), and the second locking block (142) is moved toward the hole wall of the first mounting hole (12), at which time the third stopper surface (161) comes into contact with the third contact surface (33) and locks the first terminal (3) in cooperation with the first fastener (14).

[0057] In this embodiment, a second guide surface is further installed on one side facing the first hole opening (121) of the second locking block (142), and the second guide surface is gradually inclined from one side close to the first hole opening (121) toward the center of the first mounting hole (12), thereby reducing the difficulty of moving past the second locking block (142) when one end inserted into the first mounting hole (12) of the first terminal (3) moves toward the direction of the second hole opening (122).

[0058] It can be understood that the positions of the second concave portion (31) and the second locking block (142) can be interchanged between the second elastic rock (141) and the first terminal (3).

[0059] The first locking member (5) is inserted into the insulating body (1) along the reverse direction of the third direction from one side away from the second terminal (2). Referring to FIGS. 10, 11 and 16, the avoidance groove (513) penetrates the first locking member (5) along the first direction, and a plurality of avoidance grooves (513) are installed spaced apart along the third direction.

[0060] To avoid the first locking member (5) when the first locking member (5) moves along the third direction, an avoidance groove (32) is installed in the first terminal (3), and a plurality of avoidance grooves (32) located in each first terminal (3) are arranged along the third direction.

[0061] Referring further to FIG. 16, for example, that the first terminal (3) is installed in two rows spaced apart and symmetrically along the second direction, the first locking member (5) includes a connecting part (52) and two cantilever parts (51), and the two cantilever parts (51) are each installed on opposite sides along the second direction of the connecting part (52) and are perpendicular to the connecting part (52), so that the first locking member (5) forms an approximate U shape. The avoidance groove (513) is installed in the cantilever part (51), and when the cantilever part (51) is inserted into the insulating body (1) until the first terminal (3) is in the pre-mounting position, each avoidance groove (513) of the cantilever part (51) corresponds to each first terminal (3) individually and does not affect the insertion of the first terminal (3) into the first mounting hole (12) or the detachment from the first mounting hole (12). When the cantilever part (51) is continuously inserted into the insulating body (1) until the first terminal (3) is in the final locking position, each avoidance groove (513) is arranged to be offset from each first terminal (3), thereby restricting the first terminal (3) from moving toward the direction of the second hole opening (122).

[0062] Referring to FIG. 13, in order to guide the first terminal (3) when it is inserted into the insulating body (1), two fixing grooves (18) extending along a third direction are installed on the outer wall of the insulating body (1), and each of the two fixing grooves (18) communicates with two rows of first mounting holes (12), and two cantilever parts (51) are inserted and mounted into the insulating body (1) along each of the two fixing grooves (18).

[0063] Furthermore, in order to easily observe whether the first locking member (5) is in a preliminary mounting position or a final locking position, and to improve stability when mounting the first locking member (5) to the insulating body (1), a second positioning block (514) is additionally installed on one of the first locking member (5) and the insulating body (1), and a second slit hole (19) that engages with the second positioning block (514) is installed on the other. Two second slit holes (19) are installed spaced apart along the direction in which the first locking member (5) is inserted and mounted to the insulating body (1). When the second positioning block (514) is positioned by one of the two second slit holes (19) that is further away from the second terminal (2), the first locking member (5) is in a preliminary mounting position, and the second positioning block (514) is positioned by the second of the two second slit holes (19). When positioned by one close to the terminal (2), the first locking member (5) is in the final locked position.

[0064] For example, a second positioning block (514) is installed on the cantilever portion (51) of the first locking member (5), and a second positioning block (514) is installed on each of the two cantilever portions (51), and a second slit hole (19) corresponding to the second positioning block (514) is installed on the groove side wall of each of the two fixing grooves (18).

[0065] To reduce the difficulty of the second positioning block (514) entering the second slit hole (19), the second positioning block (514) is designed in a triangular shape, and the first locking member (5) is further provided with a strip-shaped avoidance hole (515) extending along a third direction, and when the second positioning block (514) enters the second slit hole (19), the avoidance hole (515) provides an avoidance space for 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), and the mounting portion (512) and the locking portion (511) are each connected to a connecting portion (52), the mounting portion (512) can slide within a fixed groove (18), and the locking portion (511) is inserted into a first mounting hole (12), and a second positioning block (514) and an avoidance groove (513) are each installed in the mounting portion (512) and the locking portion (511), and an avoidance hole (515) is also installed in the mounting portion (512), and it can be understood that the installation of the avoidance hole (515) reduces the material cost of manufacturing the first locking member (5).

[0066] More specifically, to reduce the difficulty of detaching the first locking member (5), a force application groove (521) is further installed in the connecting part (52) to facilitate the application of force.

[0067] Referring to FIGS. 3 and FIGS. 8, the connector further includes a first sealing ring (8), the first sealing ring (8) is installed in the second hole opening (122) of the first mounting hole (12) and has a through hole (84) through which the first cable (20) can pass. The first sealing ring (8) blocks the gap between the second hole opening (122) and the first terminal (3), thereby obtaining dustproof and waterproof effects.

[0068] Referring to FIGS. 1 to 3, the connector further comprises a housing (6), the housing (6) is fixedly sleeved on the outside of the insulating body (1) and is used to protect the insulating body (1), and a gap is formed between the housing (6) and the insulating body (1) into which a mating connector is inserted. Specifically, the housing (6) has a cavity that is open along the reverse direction of the first direction, and the insulating body (1) is located in the cavity of the housing (6). A working hole (61) communicating with the cavity of the housing (6) is installed in the housing (6) at a position corresponding to the connection part (52) of the first locking member (5), and by applying force to the first locking member (5) in the direction of the second terminal (2) through the working hole (61), the first locking member (5) can be switched from a preliminary mounting position to a final locking position.

[0069] It should be emphasized that the length along the second direction of the working hole (61) is smaller than the length along the second direction of the connecting part (52), that is, the orthographic projection area of ​​the first locking member (5) in the direction of the working hole (61) is larger than the area of ​​the working hole (61), thus preventing the first locking member (5) from being detached from the insulating body (1) through the working hole (61) or being pressed into the final locking position during transportation.

[0070] Specifically, referring to FIGS. 9, 22, and 23, a third slit hole (62) is installed in the housing (6), and a third positioning block (120) is installed in the insulating body (1) to be engaged with the third slit hole (62). The third positioning block (120) is positioned within the third slit hole (62) to implement a detachable fixed connection between the insulating body (1) and the housing (6). More specifically, two third slit holes (62) are installed symmetrically along the third direction in the housing (6), and two third positioning blocks (120) are also installed to improve the stability of the connection between the housing (6) and the insulating body (1). Additionally, an inclined third guide surface is formed on one end of the third positioning block (120) facing away from the groove opening of the housing (6), thereby reducing the difficulty of inserting the third positioning block (120) into the third slit hole (62). Of course, the third slit hole (62) may be installed in the insulating body (1), and the third positioning block (120) may be installed in the housing (6).

[0071] Referring to FIG. 16, the third hole opening (111) and the first hole opening (121) of the insulating body (1) are each closed at one end toward the housing (6), and at the closed end of the housing (6), a plurality of through holes (63) are each installed at positions corresponding to the second mounting hole (11) and the first mounting hole (12) through which the second cable (10) and the first cable (20) can pass, and the mating connector can be electrically connected to the connector at the open end of the housing (6).

[0072] There is a gap between the housing (6) and one end near the opening of the housing of the insulating body (1) and the housing (6) for inserting a mating connector. To lock the mating connector into the connector, the housing (6) further includes a third fastener (64) installed on the inner wall of the housing (6), and the third fastener (64) is engaged with the connector.

[0073] Specifically, referring to FIGS. 19 and FIGS. 22, 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 housing (6), and the third recess (643) is installed at one end of the third elastic arm (641) extending toward the direction of the groove opening, and the mating connector has a third locking block formed therein that engages with the third recess (643), and the third locking block is fitted into the third recess (643) to enable locking of the mating connector.

[0074] More specifically, two third elastic rocks (641) are installed spaced apart along the third direction, and the two third elastic rocks (641) are connected by a link (642) to form a third concave portion (643) between the two third elastic rocks (641), and a third catch block is fitted into the third concave portion (643) and comes into contact with the link (642).

[0075] Referring to FIG. 19 and FIG. 23, an insertion hole (65) is formed in the closed end of the housing (6) so that a third fastener (64) is inserted into the cavity of the housing (6). The insertion hole (65) communicates with the cavity of the housing (6). A third elastic arm (641) is connected to the hole wall of the insertion hole (65) through a support point. One end connected to the link (642) of the third elastic arm (641) is inserted from the insertion hole (65) into the cavity of the housing (6), and the other end is located outside the housing (6). When releasing the locking of the third fastener (64) to the mating connector, it is sufficient to simply press the end of the third elastic arm (641) located outside the housing (6).

[0076] To further improve stability between the connector and the mating connector, the connector further includes a third locking member (7), and the third locking member (7) likewise has a preliminary mounting position and a final locking position, the third locking member (7) in the preliminary mounting 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 allows the third fastener (64) to maintain locking to the mating connector.

[0077] Referring further to FIGS. 19 and 20, the third locking member (7) is inserted into the housing (6) at one 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 preliminary mounting position is located on one side of the link (642) facing away from the opening of the housing (6), and the locking arm (71) of the third locking member (7) in the final locking position contacts the outside of the third fastener (64), thereby restricting the third fastener (64) from moving away from the third locking block. Specifically, a locking groove (72) is installed in the locking arm (71), and the link (642) is engaged within the locking groove (72) and can contact the bottom of the locking groove (72).

[0078] Referring to FIGS. 21 and 23, in order to improve the stability of mounting the third locking member (7) to the housing (6), a fourth positioning block (66) is further installed in one of the third locking member (7) and the housing (6), and a fourth slit hole (731) that engages with the fourth positioning block (66) is installed in the other, and two fourth slit holes (731) are installed spaced apart along the first direction, and when the fourth positioning block (66) engages in one of the two fourth slit holes (731) that is far from the open end of the housing (6), the fourth locking member is located in a preliminary mounting position; and when the fourth positioning block (66) engages in one of the two fourth slit holes (731) that is close to the open end of the housing (6), the fourth locking member is located in a final locking position.

[0079] For example, the third slit hole (62) is installed in the third locking member (7), and the third positioning block (120) is installed 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) installed spaced apart on opposite sides of the locking arm (71) along the third direction, each of the two positioning arms (73) is connected to the locking arm (71) and inserted into the insertion hole (65), and the third slit hole (62) is installed in the positioning arm (73). In addition, to reduce the difficulty of detaching the third locking member (7), the third locking member (7) further includes a hinge plate (74), and the hinge plate (74) connects the ends located outside the housing (6) of the locking arm (71) and the positioning arm (73).

[0080] Referring further to FIG. 23, in order to easily separate the mating connector from the connector by applying force to the third fastener (64), a U-shaped connecting block (644) is connected to one end of the link (642) of the two third elastic arms (641), that is, one end located outside the housing (6) of the two third elastic arms (641), and the two third elastic arms (641) are each connected to both ends of the connecting block (644), and by applying pressure to the connecting block (644), the third elastic arms (641) are moved in a direction away from the third locking block by lever action, thereby separating the third elastic arms (641) from the third locking block. Meanwhile, the locking arm (71) of the third locking member (7) penetrates the connecting block (644) and is inserted into the housing (6), and 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 above connector, 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 positioned in a preliminary mounting position, then the second sealing ring (9) is sleeved onto the insulating body (1), and 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 positioned in a preliminary mounting position, then the first sealing ring (8) is mounted into the mounting groove (110); then, the housing (6) is sleeved onto the insulating body (1), the third locking member (7) is inserted into the housing (6), and 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 the final locking position.

[0082] When the second terminal (2) needs to be removed from the second mounting hole (11) and replaced 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 second fastener (13) is moved in the direction of the hole wall of the second mounting hole (11) using a tool, so that the second terminal (2) can be removed from the insulating body (1), thereby effectively reducing the repair cost; When the first terminal (3) needs to be removed from the first mounting hole (12) and replaced with a new first terminal (3), the first locking member (5) can be removed from the insulating body (1) by applying a force away from the insulating body (1) along the third direction to the first locking member (5) through the force application groove (521), and then the tool can be inserted into the first mounting hole (12) and applied a force away from the first terminal (3) to the first fastener (14) to detach the first fastener (14) from the first terminal (3), thereby allowing the first terminal (3) to be detached from the insulating body (1); When the mating connector needs to be separated from the connector, pressure is applied to the opening plate (74) of the third locking member (7) to detach one 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 then pressure is applied again to the connecting block (644) of the third fastener (64) to detach one end of the third fastener (64) that is snap-coupled with the mating connector from the mating connector, thereby allowing the mating connector to be removed from the housing (6).
