Furthermore, the terms "first" and "second" are used merely for distinction in the description and have no special meaning.

[0022] An embodiment according to the present invention provides a hybrid connector and a connector assembly, wherein the connector assembly includes a hybrid connector and a docking connector (not shown) that can be fitted together with said hybrid connector. It is understood that one of the hybrid connector and the docking connector is installed on the body of an on-vehicle processing facility, such as a domain controller or an in-vehicle infotainment (IVI) system, and the other is connected via a cable to another on-vehicle facility, such as a laser radar or a gateway. Hereinafter, the specific structure of the hybrid connector will be described in detail, taking as an example the case where a cable is installed on the hybrid connector.

[0023] Referring to FIGS. 1 to 3, the hybrid connector comprises an insulating body (1), a first terminal (2), a second terminal (3), a first locking member (4), and a second locking member (5), wherein the insulating body (1) has a first mounting hole (11) and a second mounting hole (12) formed to be open, and the first terminal (2) and the second terminal (3) are installed to be inserted into the first mounting hole (11) and the second mounting hole (12), respectively, and a first fastener (13) and a second fastener (14) are installed within the first mounting hole (11) and the second mounting hole (12), respectively, and the first fastener (13) is engaged with the first terminal (2) to lock the first terminal (2) at a preset position in the first mounting hole (11), and the second fastener (14) is engaged with the second terminal (3) to lock the second terminal (3) Locking is performed at a preset position of the second mounting hole (12). Both the first locking member (4) and the second locking member (5) are installed to be detachably inserted into the insulating body (1), and the first locking member (4) can be positioned relative to the first fastener (13) so that the first fastener (13) maintains locking with respect to the first terminal (2); and the second locking member (5) can perform secondary locking with respect to the second terminal (3) which is engaged with the second fastener (14).

[0024] The above hybrid connector and connector assembly improve the connection stability between the first terminal (2) and the insulating body (1) by performing primary locking on the first terminal (2) using the first fastener (13), and then positioning the first fastener (13) using the first locking member (4) so ​​that the first fastener (13) maintains the locking on the first terminal (2); and improve the assembly stability of the entire hybrid connector by improving the connection stability between the second terminal (3) and the insulating body (1) by performing primary locking on the second terminal (3) using the second fastener (14) and performing secondary locking on the second terminal (3) using the second locking member (5).

[0025] In this embodiment, a first cable (10) and a second cable (20) are respectively connected to the first terminal (2) and the second terminal (3), and the functions of the first terminal (2) and the second terminal (3) are different. For example, if the first terminal (2) is a terminal for transmitting Ethernet signals, the first cable (10) connected to the first terminal (2) is a high-speed signal cable, and if the second terminal (3) is a low-voltage terminal for transmitting low-speed Controller Area Network (CAN) signals, the second cable (20) connected to the second terminal (3) is a low-voltage cable. To accommodate the first terminal (2) and the second terminal (3), the internal spaces of the first mounting hole (11) and the second mounting hole (12) are different, and the internal space of the first mounting hole (11) is larger than the internal space of the second mounting hole (12).

[0026] In this embodiment, the first locking member (4), the second locking member (5), and the insulating body (1) are all injection molded. Both the first locking member (4) and the second locking member (5) have a temporary mounting position and a final locking position. The first locking member (4) in the temporary mounting position allows the first terminal (2) to be inserted into the first mounting hole (11), and the first locking member (4) in the final locking position limits the position relative to the first fastener (13) to prevent the first fastener (13) from being detached from the first terminal (2); the second locking member (5) in the temporary mounting position allows the second terminal (3) to be inserted into the second mounting hole (12) or withdrawn from the second mounting hole (12), and the second locking member (5) in the final locking position locks the second terminal (3). Accordingly, during the mounting process of the hybrid connector, the first locking member (4) and the second locking member (5) are first mounted on the insulating body (1), and after positioning both of them in a temporary mounting position, the first terminal (2) and the second terminal (3) are mounted on the insulating body (1), thereby reducing the possibility of the first locking member (4) and the second locking member (5) being lost.

[0027] Specifically, referring to FIGS. 1 and 2, the first mounting hole (11) and the second mounting hole (12) are both 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). In order to reduce the difficulty of mounting the first locking member (4) and the second locking member (5) to the insulating body (1) according to the size limitations of the internal space of the first mounting hole (11) and the second mounting hole (12), the first locking member (4) moves along the first direction to implement a transition between a temporary mounting position and a final locking position, and the second locking member (5) moves along the third 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), and the third direction is perpendicular to the first direction.

[0028] In this embodiment, the first mounting hole (11) and the second mounting hole (12) are installed spaced apart along the third direction, and in the embodiment according to the present application, the number of the first mounting hole (11) and the second mounting hole (12) is not specifically limited. For example, the number of the first mounting hole (11) is 1, and the number of the second mounting hole (12) is 6, and the 6 second mounting holes (12) are arranged in 2 rows installed 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 second mounting hole (12) in any row includes 3 second mounting holes (12) installed spaced apart along the third direction, and the number of the second terminal (3) is the same as the number of the second mounting hole (12) and likewise includes 6. At this time, the second locking member (5) moving along the third direction can lock multiple second terminals (3) simultaneously, and the second direction is perpendicular to the first direction and the third direction.

[0029] Referring to FIGS. 5 to 7, the first mounting hole (11) is provided with a first hole opening (111) and a second hole opening (112) installed oppositely along a first direction, and the first hole opening (111) is installed on one side of the second hole opening (112) along the forward direction of the first direction, and the first terminal (2) can be inserted from the first hole opening (111) into the first mounting hole (11) and moved in the direction of the second hole opening (112). A first docking terminal that aligns with a first terminal (2) in a docking connector can be electrically connected to the first terminal (2) through a second hole opening (112), and a first stop surface (151) is installed on one side of the inner wall of a first mounting hole (11) near the second hole opening (112), and the first stop surface (151) can come into contact with a first contact surface (211) of the first terminal (2), thereby restricting the first terminal (2) from continuing to move in the direction of the second hole opening (112) so that the first terminal (2) is inserted into a preset position of the first mounting hole (11).

[0030] Specifically, referring to FIGS. 5 and FIGS. 12, two first position limiting blocks (15) are installed facing each other along a second direction on the inner wall surface of the first mounting hole (11), and a first stop 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 first mounting hole (11) from one end close to the first hole opening (111) toward one end moving away from the first hole opening (111). Correspondingly, a first contact surface (211) is also installed at an angle.

[0031] Referring to FIGS. 6 and 7, a first concave portion (221) is installed on the outer wall surface of the first terminal (2), and the first fastener (13) includes a first elastic arm (131) and a first locking block (132) formed integrally, and one end of the first elastic arm (131) near the first hole opening (111) is connected to the hole wall of the first mounting hole (11), and the other end gradually moves away from the hole wall of the first mounting hole (11) toward the direction of the second hole opening (112), and the first locking block (132) is installed on one side of the first elastic arm (131) that moves away from the hole wall of the first mounting hole (11).

[0032] After the first terminal (2) is inserted from the first hole opening (111) into the first mounting hole (11), the first fastener (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 first mounting hole (11), until the first locking block (132) is locked and inserted into the first concave portion (221), at which time the first stop surface (151) comes into contact with the first contact surface (211), and the first fastener (13) locks the first terminal (2) to prevent the first terminal (2) from moving toward the first hole opening (111).

[0033] Specifically, two first fasteners (13) are installed symmetrically along the third direction within the first mounting hole (11) to improve the locking stability of the first fasteners (13) with respect to the first terminal (2). More specifically, two first 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 first fasteners (13).

[0034] More specifically, a first guide surface is installed on one side of the first locking block (132) facing the first hole opening (111), and the first guide surface gradually moves away from the hole wall of the first mounting hole (11) from one side close to the first hole opening (111) toward one side away from the first hole opening (111), thereby reducing the difficulty of the first locking block (132) when one end inserted into the first mounting hole (11) of the first terminal (2) moves toward the second hole opening (112).

[0035] In this embodiment, to reduce the difficulty of installing the first terminal (2) by inserting it into the first mounting hole (11), the area of ​​the first hole opening (111) is larger than the maximum cross-sectional area of ​​the first terminal (2). Based on this, the hybrid connector further includes an end cover (30), the end cover (30) is mounted on the insulating body (1) and is located on one side of the first hole opening (111) of the first mounting hole (11), and a threading hole through which the first cable (10) passes is formed in the end cover (30), and the area of ​​the threading hole is smaller than the area of ​​the first hole opening (111).

[0036] After inserting the first terminal (2), to which the first cable (10) is connected, into the first mounting hole (11), the end cover (30) is mounted on the insulating body (1), thereby reducing the possibility of shaking of the first cable (10) and improving the stability of the entire hybrid connector. Specifically, the end cover (30) is connected to the insulating body (1) via a snap fit, making it convenient to inspect and replace the first terminal (2).

[0037] Referring to FIG. 15, the first terminal (2) includes a front shielding case (21), an inner conductor, a cable clip, and a rear shielding case (22). The rear end of the front shielding case (21) is sleeved to the rear shielding case (22) and connected to the rear shielding case (22) by compression. The inner conductor is located within the front shielding case (21) and is used to electrically connect the first docking terminal and the cable. The cable clip is located within the rear shielding case (22) and is used to secure one end of the cable within the rear shielding case (22). The front shielding case (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, the rear shielding case (22) is installed in a dumbbell shape, and the first concave portion (221) is an annular groove formed in the rear shielding case (22), and the annular groove is located on the outside of the front shielding case (21).

[0038] In other embodiments, it can be understood that the first concave portion (221) is installed in the first elastic rock (131), and the first locking block (132) can be installed in the first terminal (2).

[0039] Referring to FIGS. 12 and 15, in order to prevent damage to the first terminal (2) or the insulating body (1) caused by the first terminal (2) being inserted into the first mounting hole (11) being too deep, 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 second hole opening (112) is closed, and a guide block (212) that slides together with the guide groove (152) is installed on the outer wall surface of the first terminal (2), and when the first terminal (2) is in a preset position within the first mounting hole (11), the guide block (212) comes into contact with the groove wall of one end of the guide groove (152) near the second hole opening (112). Specifically, the guide block (212) is installed on the outer wall surface of the large diameter section.

[0040] Referring to FIG. 14, the first locking member (4) includes a sleeve portion (41) and an insertion connection portion (42), the sleeve portion (41) is connected to the insertion connection portion (42) and is located outside the insertion connection portion (42), and a narrow space is formed between the sleeve portion (41) and the insertion connection portion (42) that is open toward the direction of the first hole opening (111), the insertion connection portion (42) is installed to be inserted into the first mounting hole (11) from the second hole opening (112), and the sleeve portion (41) is sleeved on the outside of the insulating body (1) so that the insulating body (1) is fitted into the narrow space.

[0041] The first locking member (4) is inserted into the first mounting hole (11) from the second hole opening (112). Referring to FIGS. 6 and 7, when the first locking member (4) is in a temporary mounting position, the first locking member (4) and the first fastener (13) are installed spaced apart along the first direction, and since the first locking member (4) does not interfere with the deformation of the first fastener (13), the first terminal (2) can be inserted into a preset position of the first mounting hole (11) from the first hole opening (111); When the first locking member (4) is in the final locked position, the first fastener (13) moves toward the first terminal (2) along the first direction, and the inner side of the insertion connection part (42) comes into contact with one side of the first fastener (13) facing away from the first terminal (2), and is restricted by the insertion connection part (42), so that the first fastener (13) no longer has the ability to deform toward the hole wall of the first mounting hole (11) and is always caught on the first terminal (2), thereby maintaining stability when the first terminal (2) is installed to be inserted into the first mounting hole (11). It should be emphasized that when the first locking member (4) is in the final locked position, the cross-section of the insulating body (1) comes into contact with one side of the narrow space away from the opening, thereby restricting the first locking member (4) from continuing to move toward the first hole opening (111).

[0042] Specifically, a stepped surface (421) is formed at one end of the insertion connection part (42) inserted into the first mounting hole (11), and when the first locking member (4) is in the final locked position, the first fastener (13) contacts the stepped surface (421) to determine the final locked position of the first locking member (4) and further reduce the possibility of the first locking member (4) being excessively inserted into the first mounting hole (11).

[0043] Additionally, a second stop surface (422) is further installed on one side of the first locking member (4) facing the first terminal (2), and the second stop surface (422) gradually moves away from the hole wall of the first mounting hole (11) from one end close to the first hole opening (111) toward one end moving away from the first hole opening (111), and a second contact surface (213) that is coupled with the second stop surface (422) is formed on the outer wall surface of the first terminal (2). When the first locking member (4) is in the final locked position, the second stop surface (422) contacts the second contact surface (213) and, in cooperation with the first stop surface (151) and the first contact surface (211), additionally restricts the first terminal (2) from moving in the direction of the second hole opening (112).

[0044] More specifically, two second stop surfaces (422) are installed facing the inner wall of the first locking member (4), and correspondingly, two second contact surfaces (213) are also installed, and the two second contact surfaces (213) are likewise formed between the small diameter section and the large diameter section of the front shielding case (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.

[0045] Referring to FIGS. 5 and 9, in order to easily observe whether the first locking member (4) is in a temporary mounting position or a final locking position and to improve stability when mounting the first locking member (4) to the insulating body (1), a first positioning block (17) is further installed in one of the first locking member (4) and the insulating body (1), and a first groove hole (43) that engages with the first positioning block (17) is installed in the other. Two first groove holes (43) are installed spaced apart along a first direction. When the first positioning block (17) is positioned in one of the two first groove holes (43) that is further away from the second hole opening (112), the first locking member (4) is in a temporary mounting position. When the first positioning block (17) is positioned in one of the two first groove holes (43) that is closer to the second hole opening (112), The first locking member (4) is in the final locked position.

[0046] For example, the first positioning block (17) is installed in the insulating body (1), and the first groove hole (43) is installed in the first locking member (4). Specifically, the cross-section of the first positioning block (17) is installed as an equilateral trapezoid or an equilateral triangle with chamfered corners, thereby reducing the difficulty of the first positioning block (17) entering and exiting the first groove hole (43).

[0047] Referring to FIG. 14, in order to reduce the difficulty of the first locking member (4) being detached from the insulating body (1), a clearance notch (411) is formed in the sleeve portion (41), and the clearance notch (411) extends along the first direction to the cross-section of the sleeve portion (41) near the first terminal (2). When the first locking member (4) is detached, if a force is applied to the sleeve portion (41) moving away from the insulating body (1) along the second direction, the first positioning block (17) can be detached from the first groove hole (43).

[0048] Referring to FIG. 8, the second mounting hole (12) is provided with a third hole opening (121) and a fourth hole opening (122) installed oppositely along the first direction, wherein the third hole opening (121) and the first hole opening (111) are located on the same side of the insulating body (1), and a third stop surface (161) is installed on one side of the second mounting hole (12) near the fourth hole opening (122), and the third stop surface (161) can come into contact with the third contact surface (33) of the second terminal (3), thereby restricting the second terminal (3) from continuing to move toward the direction of the fourth hole opening (122) so that the second terminal (3) is inserted into a preset position of the second mounting hole (12).

[0049] Specifically, an annular second position limiting block (16) is installed on one side of the second mounting hole (12) near the fourth hole opening (122), and a third stop surface (161) is formed on one side of the second position limiting block (16) facing away from the fourth hole opening (122) and is installed as a conical surface, which gradually expands from one end near the fourth hole opening (122) toward one end away from the fourth hole opening (122), and a conical third contact surface (33) is formed on the outer wall surface of the second terminal (3), and when the third contact surface (33) contacts the third stop surface (161), the second terminal (3) is inserted into a preset position of the second mounting hole (12).

[0050] Referring to FIGS. 8 and FIGS. 17, a second recess (31) is installed on the outer wall surface of the second terminal (3), and the second fastener (14) includes a second elastic arm (141) and a second locking block (142) that are integrally molded. One end of the second elastic arm (141) near the third hole opening (121) is connected to the hole wall of the second mounting hole (12), and the other end gradually moves away from the hole wall of the second mounting hole (12) toward the direction of the fourth hole opening (122), and the second locking block (142) is installed on one side of the second elastic arm (141) that moves away from the hole wall of the second mounting hole (12). Specifically, the second recess (31) is a groove formed to be open on the outer wall surface of the second terminal (3).

[0051] After the second terminal (3) is inserted into the second mounting hole (12) from the third hole opening (121), it can press the second fastener (14), and the second elastic arm (141) is deformed to move the second locking block (142) toward the hole wall of the second mounting hole (12), moving until the second locking block (142) is locked and inserted into the second concave portion (31), at which time the third stop surface (161) comes into contact with the third contact surface (33), and locking of the second terminal (3) is performed in cooperation with the second fastener (14).

[0052] In this embodiment, a second guide surface is further installed on one side of the second locking block (142) facing the third hole opening (121), and the second guide surface gradually slopes from one side closer to the third hole opening (121) toward the center of the second mounting hole (12), thereby reducing the difficulty of the second locking block (142) when one end inserted into the second mounting hole (12) of the second terminal (3) moves toward the fourth hole opening (122).

[0053] 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 arm (141) and the second terminal (3).

[0054] The second locking member (5) is inserted into the insulating body (1) along the reverse direction of the third direction from one side away from the first terminal (2). In this embodiment, referring to FIGS. 10, 11 and 16, the second locking member (5) has an avoidance groove (513) installed to penetrate along the first direction, and the avoidance groove (513) of the second locking member (5) in the temporary mounting position is opposite to the second terminal (3), allowing the second terminal (3) to be inserted into or removed from the second mounting hole (12), and the avoidance groove (513) of the second locking member (5) in the final locking position is offset from the second terminal (3), so that the second terminal (3) is locked within the second mounting hole (12).

[0055] A clearance groove (32) is installed in the second terminal (3) to avoid the second locking member (5) when the second locking member (5) moves along the third direction. Based on the premise that the second terminal (3) is installed in a row along the third direction, multiple clearance grooves (32) located in each second terminal (3) are arranged along the third direction, and the second locking member (5) is installed with the same number of avoidance grooves (513) as the second terminal (3).

[0056] In other embodiments, the second locking member (5) may also adopt a locking coupling method to lock the second terminal (3).

[0057] For example, in which the second terminal (3) is installed in two rows spaced apart and symmetrically along the second direction, referring further to FIG. 16, the second 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 second locking member (5) forms an approximate U shape. Based on the installation of the avoidance groove (513), the avoidance groove (513) is installed in the cantilever part (51). When the cantilever part (51) is inserted into the insulating body (1) until the second terminal (3) is in a temporary mounting position, each avoidance groove (513) of the cantilever part (51) corresponds to each second terminal (3) individually, so as not to affect whether the second terminal (3) is inserted into or removed from the second mounting hole (12). When the cantilever part (51) is continuously inserted into the insulating body (1) until the second terminal (3) is in a final locking position, each avoidance groove (513) is misaligned with each second terminal (3), thereby restricting the second terminal (3) from moving toward the direction of the fourth hole opening (122).

[0058] Referring to FIG. 13, in order to provide guidance to the second terminal (3) when the second 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 second mounting holes (12), and two cantilevered members (51) are mounted to be inserted into the insulating body (1) along each of the two fixing grooves (18).

[0059] Furthermore, in order to easily observe whether the second locking member (5) is in a temporary mounting position or a final locking position and to improve stability when mounting the second locking member (5) to the insulating body (1), a second positioning block (514) is further installed in one of the second locking member (5) and the insulating body (1), and a second groove hole (19) that engages with the second positioning block (514) is installed in the other. Two second groove holes (19) are installed spaced apart along a third direction. When the second positioning block (514) is positioned in one of the two second groove holes (19) that is further away from the first terminal (2), the second locking member (5) is in a temporary mounting position, and when the second positioning block (514) is positioned in one of the two second groove holes (19) that is closer to the first terminal (2), the second locking member (5) is in a final locking position. there is.

[0060] For example, a second positioning block (514) is installed on the cantilever portion (51) of the second locking member (5), and a second positioning block (514) is installed on each of the two cantilever portions (51), and a second groove hole (19) corresponding to the second positioning block (514) is installed on the groove side wall of each of the two fixing grooves (18).

[0061] To reduce the difficulty of the second positioning block (514) entering the second groove hole (19), the second positioning block (514) is designed in a triangular shape, and additionally, the second locking member (5) is further provided with a strip-shaped clearance hole (515) extending along a third direction, and when the second positioning block (514) enters the second groove hole (19), the clearance hole (515) provides a space to avoid deformation of the second locking member (5). Specifically, the cantilever part (51) further includes an L-shaped mounting part (512) and a locking part (511), 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), and the locking part (511) is inserted into a second 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 a strip-shaped clearance hole (515) extending in a third direction is formed to be open in the mounting part (512), thereby increasing the plasticity of the second locking member (5), reducing the difficulty of switching between the temporary mounting position and the final locking position of the second locking member (5), and also reducing the material cost for manufacturing the second locking member (5).

[0062] More specifically, to reduce the difficulty of detaching the second locking member (5), a force application groove (521) is formed more openly in the connecting part (52) to facilitate force application, and the force application groove (521) extends to the surface of the connecting part (52) along the reverse direction of the first direction.

[0063] Referring to FIGS. 3 and FIGS. 8, the hybrid connector further includes a first sealing ring (8), the first sealing ring (8) is installed in the fourth hole opening (122) of the second mounting hole (12) and is formed to have a through hole (84) through which the second cable (20) passes, and the first sealing ring (8) blocks the gap between the fourth hole opening (122) and the second terminal (3) to obtain dustproof and waterproof effects.

[0064] Referring to FIG. 24, based on the premise that multiple second terminals (3) are installed, the first sealing ring (8) is a group sealing ring, and the group sealing ring is provided with multiple through holes (84) that correspond to each of the multiple second mounting holes (12). Specifically, the insulating body (1) has a mounting groove (110) formed to be open and communicating with each second mounting hole (12), and the first sealing ring (8) is mounted within the mounting groove (110). To improve the sealing performance of the first sealing ring (8), the first sealing ring (8) includes a sealing body (83) and a plurality of first annular protrusions (81) installed at intervals on the outer wall surface of the sealing body (83) along the first direction. The first annular protrusions (81) are installed in an annular shape, thereby increasing the contact area with the groove side wall of the mounting groove (110) and improving the sealing performance. Additionally, a plurality of second annular protrusions (82) are installed at intervals along the first direction on the hole wall of each through hole (84), and the second annular protrusions (82) are also installed in an annular shape, thereby increasing the contact area with the second cable (20) and improving the sealing performance.

More specifically, two third groove holes (62) are installed symmetrically along the third direction in the housing (6), and two third positioning blocks (120) are also installed, thereby improving the stability of the connection between the housing (6) and the insulating body (1). Additionally, an inclined third guide surface is installed at one end of the third positioning block (120) facing away from the groove opening of the housing (6), thereby reducing the difficulty of engaging and inserting the third positioning block (120) into the third groove hole (62). Of course, the third groove hole (62) may be installed in the insulating body (1), and the third positioning block (120) may be installed in the housing (6).
