[0021] In the description of the present embodiment, the directional or positional relationships indicated by terms such as "up," "down," "left," and "right" are based on the directions or positions shown in the attached drawings. This is intended merely to facilitate explanation and simplify the process, and does not imply or suggest 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 component are provided, wherein the connector component includes a connector and a mating connector that is fitted together with the connector, wherein the connector is connected to equipment via a cable, and the mating connector is installed on the main body of another piece of equipment. The equipment having the mating connector may be, but is not limited to, vehicle-mounted processing equipment such as a domain controller or IVI, and the connector may be, but is not limited to, vehicle-mounted equipment connected to vehicle-mounted processing equipment such as a laser radar or a gateway.

[0023] Referring to FIGS. 1, 3, 8 and 24, the connector comprises an insulating body (1), a first terminal (3), a first sealing ring (8) and a second sealing ring (9). A plurality of first mounting holes (12) with the same extension direction are opened in the insulating body (1). A first orifice (121) and a second orifice (122) are installed oppositely in the first mounting holes (12). A plurality of first terminals (3) are inserted into the first mounting holes (12) from each first orifice (121) in a corresponding manner. A first counterpart terminal that matches the first terminal (3) of the counterpart connector can be electrically connected to the first terminal (3) through the second orifice (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 orifice (121). A first sealing ring (8) is fixed to one side near the first orifice (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 first cables (20) are opened in the first sealing ring (8). The first cables (20) pass through the through holes (84) and come 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).

[0024] The above connector and connector component seal the first cable (20) and the insulating body (1) using the first sealing ring (8), and seal the connector and the mating connector using the second sealing ring (9), thereby improving the sealing performance of the entire connector component and providing excellent dustproof and waterproof effects. In addition, the first sealing ring (8) can simultaneously seal multiple first terminals (3) and the insulating body (1), thereby simplifying the difficulty of mounting the connector and connector component.

[0025] Referring to FIG. 8, a mounting groove (110) is installed on one side of the insulating body (1) near the first orifice (121) to connect each first mounting hole (12), and a first sealing ring (8) is installed in the mounting groove (110) and contacts the 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 counterpart connector, and improving the sealing performance.

[0028] Referring to FIGS. 1 to 3 and FIGS. 6 and FIG. 12, the connector further comprises a second terminal (2), a second locking member (4), and a first locking member (5), and the first locking member (5), the second locking member (4), and the insulating body (1) are each manufactured by injection molding. A second mounting hole (11) is further opened in the insulating body (1), and the second terminal (2) is inserted and installed within the second mounting hole (11). A second latch (13) is installed within the second mounting hole (11), and a first latch (14) is installed within the first mounting hole (12). The second latch (13) is used to lock the second terminal (2) to a preset position in the second mounting hole (11), and the first latch (14) is used to lock the first terminal (3) to a preset position in the first mounting hole (12). The second locking member (4) and the first locking member (5) are detachably installed in the insulating body (1), and the second locking member (4) and the first locking member (5) each have a temporary mounting position and a final locking position, 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 allows the second latch (13) to maintain locking to the second terminal (2); the first locking member (5) in the temporary mounting position allows the first terminal (3) to be inserted into the first mounting hole (12) or removed from the first mounting hole (12), and the first locking member (5) in the final locking position can lock to the first terminal (3).

[0029] The above connector performs primary locking on the second terminal (2) using the second latch (13), and then positions the second latch (13) using the second locking member (4) so ​​that the second latch (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 latch (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. In addition, the first locking member (5), the second locking member (4), and the insulating body (1) are each injection-molded, and the first locking member (5) and the second locking member (4) can be pre-mounted in the insulating body (1) to a temporary mounting position and then transported, thereby reducing the possibility of losing the first locking member (5) and the second locking member (4) and also reducing the difficulty of subsequent assembly.

[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) can be fixedly sleeved to 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). In order to reduce the difficulty of mounting the second locking member (4) and the first locking member (5) to the insulating body (1) according to the size limitation of the internal space of the second mounting hole (11) and the first mounting hole (12), the second locking member (4) moves along the first direction to implement a transition between the temporary mounting position and the final locking position, and the first locking member (5) moves along the third direction to implement a transition between the temporary 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) of any row include 3 first mounting holes (12) installed spaced apart along the third direction. 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 orifice (111) and a fourth orifice (112) are installed facing each other along a first direction in the second mounting hole (11), and the third orifice (111) is installed on one side of the fourth orifice (112) according to the forward direction of the first direction, and the second terminal (2) can be inserted from the third orifice (111) into the second mounting hole (11) and move toward the fourth orifice (112). A second counterpart terminal that matches the second terminal (2) on the counterpart connector can be electrically connected to the second terminal (2) through the fourth orifice (112), and a first stopper surface (151) is installed on one side of the inner wall of the second mounting hole (11) close to the fourth orifice (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 continuing to move in the direction of the fourth orifice (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 orifice (111) toward one end moving away from the third orifice (111). Correspondingly, a first contact surface (211) is also installed at an angle.

[0036] Referring to FIGS. 6, 7, and 15, a first concave portion (221) is installed on the outer wall surface of the second terminal (2), and the second latch (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 orifice (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 orifice (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 orifice (111), the second latch (13) can be pressed, and the first elastic arm (131) is deformed to move the first locking block (132) toward the hole wall of the second mounting hole (11). When the first locking block (132) is inserted into the first concave portion (221), the first stopper surface (151) comes into contact with the first contact surface (211), and the second latch (13) locks the second terminal (2) to prevent the second terminal (2) from moving toward the third orifice (111).

[0038] Specifically, two second latches (13) are installed symmetrically along the third direction within the second mounting hole (11) to improve the locking stability of the second latches (13) with respect to the second terminal (2). More specifically, two second latches (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 latches (13).

[0039] More specifically, a first guide surface is installed on one side facing the third orifice (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 orifice (111) toward one side away from the third orifice (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 orifice (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 orifice (111) is larger than the maximum cross-sectional area of ​​the second terminal (2). Based on this, the connector further includes a finishing cap (30) which is mounted on the insulating body (1) and is located on one side of the third orifice (111) of the second mounting hole (11), and the finishing cap (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 orifice (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 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 cap (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 surface of the first position limiting block (15), and one side of the guide groove (152) near the fourth orifice (112) is closed, and a guide block (212) that slides into the guide groove (152) is installed on the outer wall surface 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 orifice (112) of the guide groove (152). Specifically, the guide block (212) is installed on the outer wall surface 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 open toward the direction of the third orifice (111), and the insertion connection part (42) is inserted into the second mounting hole (11) from the fourth orifice (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 orifice (112). Referring to FIGS. 6 and 7, when the second locking member (4) is in a temporary mounting position, the second locking member (4) and the second latch (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 latch (13), the second terminal (2) can be inserted from the third orifice (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 latch (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 latch (13), and is restricted by the insertion connection part (42), so that the second latch (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 orifice (111).

[0047] Specifically, referring to FIG. 14, 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 latch (13) contacts the stepped surface (421) to confirm the final locked position of the second locking member (4) and further reduce 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 orifice (111) toward one end moving away from the third orifice (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) comes into contact with the second contact surface (213) and is coupled with the first stopper surface (151) and the first contact surface (211) to further restrict the movement of the second terminal (2) toward the fourth orifice (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 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 temporary 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 in one of the two first slit holes (43) that is further away from the fourth orifice (112), the second locking member (4) is in a temporary mounting position. When the first positioning block (17) is positioned in one of the two first slit holes (43) that is closer to the fourth orifice (112), 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 orifice (121) and the third orifice (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 orifice (122) of the first mounting hole (12). 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 orifice (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 orifice (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 orifice (122) and is installed as a conical surface, which gradually expands from one end close to the second orifice (122) toward one end away from the second orifice (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).

One end of the second elastic arm (141) near the first orifice (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 orifice (122). The second locking block (142) is installed on one side of the second elastic arm (141) 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 from the first orifice (121) into the first mounting hole (12), the first latch (14) can be pressed, and the second elastic arm (141) is deformed to move the second locking block (142) toward the hole wall of the first mounting hole (12), and when the second locking block (142) is inserted into the second concave portion (31), the third stopper surface (161) comes into contact with the third contact surface (33), and the first terminal (3) is locked under the engagement of the first latch (14).

[0057] In this embodiment, a second guide surface is further installed on one side facing the first orifice (121) of the second locking block (142), and the second guide surface is gradually inclined from one side close to the first orifice (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 orifice (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 first locking member (5) is provided with an avoidance groove (513) installed through it along the first direction, and the avoidance groove (513) of the first locking member (5) in the temporary mounting position is opposite to the first terminal (3) to allow the first terminal (3) to be inserted into or removed from the first mounting hole (12), and the avoidance groove (513) of the first locking member (5) in the final locking position and the first terminal (3) are arranged offset from each other so that the first terminal (3) is locked within the first mounting hole (12).

[0060] An avoidance groove (32) is installed in the first terminal (3) to avoid the first locking member (5) when the first locking member (5) moves along the third direction. Based on the premise that the first terminal (3) is arranged in a line along the third direction, a plurality of avoidance grooves (32) located in each first terminal (3) are arranged along the third direction, and the first locking member (5) is provided with the same number of avoidance grooves (513) as the first terminal (3).

[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), the connecting part (52) extends along the second direction, and the two cantilever parts (51) are each installed on opposite sides of the connecting part (52) along the second direction 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 a temporary 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 removal 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 a 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 orifice (122).

[0062] Referring to FIG. 13, in order to provide guidance to the first terminal (3) when the first terminal (3) 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 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 temporary 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, and two second slit holes (19) are installed spaced apart along a third direction, and when the second positioning block (514) is positioned in one of the two second slit holes (19) that is farther from the second terminal (2), the first locking member (5) is in a temporary mounting position, and when the second positioning block (514) is positioned in one of the two second slit holes (19) that is closer to the second terminal (2), the first locking member (5) It 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), a strip-shaped avoidance hole (515) extending along a third direction is further installed in the first locking member (5), 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 part (51) includes a mounting part (512) and a locking part (511) installed in an L-shape, and the mounting part (512) and the locking part (511) are each connected to a connecting part (52), the mounting part (512) can slide within a fixed groove (18), the locking part (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 part (512) and the locking part (511), and an avoidance hole (515) is also installed in the mounting part (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.
