Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and particularly to a hybrid connector and a connector assembly. Background Art

[0002] As a kind of vehicle-mounted sensor, a lidar can transmit the sensed information to a vehicle-mounted processing device. With the increasing demand for intelligence, the amount of sensed information is increasing day by day. There is a high-speed transmission requirement between the lidar and the vehicle-mounted processing device. In addition, there is also a low-speed transmission requirement for less data volume such as control information between the vehicle-mounted processing device and the lidar. In order to reduce the requirement for wiring space, the lidar is connected to the vehicle-mounted processing device through a hybrid connector.

[0003] In the prior art, a hybrid connector generally includes an insulating body and at least two kinds of terminals with different functions arranged in the insulating body. In order to lock each terminal in the insulating body, a buckle portion adapted to be snapped onto the insulating body is formed on the terminal itself. However, in a complex transportation or application environment, the hybrid connector may encounter sudden situations such as mechanical vibration, impact, and temperature change. These situations may cause the buckle portion to disengage from the insulating body, and then cause the terminal to disengage from the insulating body, affecting the assembly stability of the hybrid connector and the signal connection stability between the hybrid connector and the mating connector. Summary of the Invention

[0004] The purpose of the present invention is to provide a hybrid connector, which can solve the problem of unstable performance of the hybrid connector and the connector assembly caused by the unstable connection between each terminal and the insulating body.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] A hybrid connector includes an insulating body, a first terminal, a second terminal, a first locking member, and a second locking member. The insulating body is provided with a first mounting hole and a second mounting hole. A first fastening member is arranged in the first mounting hole, and a second fastening member is arranged in the second mounting hole. The first terminal is inserted into the first mounting hole and is in snap-fit with the first fastening member. The first locking member is detachably inserted into the insulating body and is in limit cooperation with the first fastening member. The second terminal is inserted into the second mounting hole and is in snap-fit with the second fastening member. The second locking member is detachably inserted into the insulating body and locks the second terminal that is in snap-fit with the second fastening member.

[0007] Optionally, the first locking member has a pre-installed position and a final locking position relative to the insulating body. The first locking member in the pre-installed position allows the first terminal to be inserted into the first mounting hole, and the insulating body in the final locking position limits the first terminal; and / or, the second locking member has a pre-installed position and a final locking position relative to the insulating body. The second locking member in the pre-installed position allows the second terminal to be inserted into or pulled out from the second mounting hole, and the second locking member in the final locking position locks the second terminal.

[0008] Optionally, both the first mounting hole and the second mounting hole extend in a first direction. The first locking member moves along the first direction to switch between the pre-installed position and the final locking position, and the second locking member moves along a third direction to switch between the pre-installed position and the final locking position. The third direction is perpendicular to the first direction.

[0009] Optionally, the first locking member includes a socket portion and a plug portion. The socket portion is connected to the plug portion and is located outside the plug portion. The socket portion is sleeved outside the insulating body. When the first locking member is in the final locking position, the inner side of the plug portion abuts against the side of the first fastener facing away from the first terminal.

[0010] Optionally, an avoidance groove is provided on the second locking member. The avoidance groove on the second locking member in the pre-installed position is opposite to the second terminal, and the avoidance groove on the second locking member in the final locking position is offset from the second terminal.

[0011] Optionally, the hybrid connector further includes a housing, and the housing is sleeved on the insulating body.

[0012] Optionally, an operation hole is formed on one side of the housing corresponding to the second locking member. The orthographic projection area of the second locking member in the direction of the operation hole is larger than the area of the operation hole.

[0013] Optionally, the connector further includes a third locking member, and the third locking member is inserted into the housing and locks a docking connector that is inserted and mated with the connector.

[0014] Optionally, the first terminal is a terminal for transmitting Ethernet signals, and the second terminal is a low-voltage terminal.

[0015] A connector assembly includes the above-mentioned hybrid connector and a docking connector that is inserted and mated with the hybrid connector.

[0016] Advantages of the present invention: In the hybrid connector and connector assembly proposed in the present invention, the first fastener is used to lock the first terminal once, and then the first locking member is used to limit the first fastener, so that the first fastener maintains the locking of the first terminal, improving the connection stability between the first terminal and the insulating body; while the second fastener locks the second terminal once, and the second locking member locks the second terminal twice, improving the connection stability between the second terminal and the insulating body, thereby improving the performance stability of the entire hybrid connector and the connector.

[0055] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only for explaining the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only parts related to the present invention rather than all structures are shown in the drawings.

In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0059] In an embodiment of the present invention, a hybrid connector and a connector assembly are provided. The connector assembly includes a hybrid connector and a pair of docking connectors (not shown in the figure) that can be plugged and mated with the hybrid connector. It can be understood that one of the hybrid connector and the docking connector is provided on the device main body of a device, such as an in-vehicle processing device like a domain controller or IVI, and the other is connected to another device such as a lidar, a gateway, etc. through a cable. Hereinafter, taking the hybrid connector being provided with a cable as an example, the specific structure of the hybrid connector will be described in detail.

[0060] Refer to Figures 1 - 3As shown in the figure, the hybrid connector includes an insulating body 1, a first terminal 2, a second terminal 3, a first locking member 4, and a second locking member 5. The insulating body 1 is provided with a first mounting hole 11 and a second mounting hole 12. The first terminal 2 and the second terminal 3 are respectively inserted into the first mounting hole 11 and the second mounting hole 12. A first fastening member 13 and a second fastening member 14 are respectively arranged in the first mounting hole 11 and the second mounting hole 12. The first fastening member 13 is in snap-fit with the first terminal 2 to lock the first terminal 2 at a preset position in the first mounting hole 11, and the second fastening member 14 is in snap-fit with the second terminal 3 to lock the second terminal 3 at a preset position in the second mounting hole 12. The first locking member 4 and the second locking member 5 are both detachably inserted into the insulating body 1. The first locking member 4 can limit the first fastening member 13 to keep the first fastening member 13 locking the first terminal 2. The second locking member 5 can perform secondary locking on the second terminal 3 that is in snap-fit with the second fastening member 14.

[0061] The above hybrid connector and connector assembly use the first fastening member 13 to perform primary locking on the first terminal 2, and then use the first locking member 4 to limit the first fastening member 13 to keep the first fastening member 13 locking the first terminal 2, improving the connection stability between the first terminal 2 and the insulating body 1. The second fastening member 14 performs primary locking on the second terminal 3, and the second locking member 5 performs secondary locking on the second terminal 3, improving the connection stability between the second terminal 3 and the insulating body 1, thereby improving the assembly stability of the entire hybrid connector.

[0062] In this embodiment, the first terminal 2 and the second terminal 3 are respectively connected to a first cable 10 and a second cable 20, 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. If the second terminal 3 is a low-voltage terminal for transmitting low-speed CAN signals, the second cable 20 connected to the second terminal 3 is a low-voltage cable. To adapt to 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.

[0063] 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 pre-installed position and a final locking position. The first locking member 4 in the pre-installed 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 first fastener 13 to prevent the first fastener 13 from detaching from the first terminal 2; the second locking member 5 in the pre-installed position allows the second terminal 3 to be inserted into or pulled out of the second mounting hole 12, and the second locking member 5 in the final locking position locks the second terminal 3. During the assembly process of the hybrid connector, the first locking member 4 and the second locking member 5 can be first assembled on the insulating body 1 and both are in the pre-installed position, and then the first terminal 2 and the second terminal 3 are assembled onto the insulating body 1 to reduce the possibility of loss of the first locking member 4 and the second locking member 5.

[0064] Specifically, referring to Figure 1 and Figure 2 as shown, both the first mounting hole 11 and the second mounting hole 12 extend along the first direction ( Figure 1 the X direction and its reverse direction in , where the X direction is the positive direction of the first direction, and the reverse direction of the X direction is the reverse direction of the first direction). Due to the limitation of the internal space size of the first mounting hole 11 and the second mounting hole 12, in order to reduce the difficulty of assembling the first locking member 4 and the second locking member 5 on the insulating body 1, the first locking member 4 realizes the switching between the pre-installed position and the final locking position by moving along the first direction, and the second locking member 5 realizes the switching between the pre-installed position and the final locking position by moving along the third direction ( Figure 1 the Z direction and its reverse direction in , where the Z direction is the positive 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.

[0065] In this embodiment, the first mounting hole 11 and the second mounting hole 12 are arranged at intervals along the third direction. As for the number of the first mounting hole 11 and the second mounting hole 12, no specific limitation is made in the embodiments of the present application. Exemplarily, the number of the first mounting hole 11 is 1, and the number of the second mounting hole 12 is 6. The 6 second mounting holes 12 are arranged in two rows symmetrically along the second direction ( Figure 1 the Y direction and its reverse direction in , where the Y direction is the positive direction of the second direction, and the reverse direction of the Y direction is the reverse direction of the second direction). Any row of the second mounting holes 12 includes three second mounting holes 12 arranged at intervals along the third direction. The number of the second terminals 3 is the same as the number of the second mounting holes 12, and also includes 6. At this time, the second locking member 5 moving along the third direction can lock a plurality of second terminals 3 at the same time, and the second direction is perpendicular to the first direction and the third direction.

[0066] Referring to Figures 5 - 7As shown, the first mounting hole 11 has a first orifice 111 and a second orifice 112 oppositely arranged in a first direction, and the first orifice 111 is arranged on the positive side of the second orifice 112 along the first direction. The first terminal 2 can be inserted into the first mounting hole 11 from the first orifice 111 and move towards the second orifice 112. The first docking terminal on the docking connector adapted to the first terminal 2 can be electrically connected to the first terminal 2 through the second orifice 112. A first stop surface 151 is provided on one side of the inner wall of the first mounting hole 11 close to the second orifice 112. The first stop surface 151 can abut against the first abutting surface 211 on the first terminal 2, thereby restricting the first terminal 2 from continuing to move towards the second orifice 112 and enabling the first terminal 2 to be inserted into a preset position of the first mounting hole 11.

[0067] Specifically, referring to Figure 5 and Figure 12 As shown, two first limiting blocks 15 are oppositely arranged on the inner wall surface of the first mounting hole 11 in a second direction. The first stop surface 151 is formed on the inner side surface of the first limiting block 15 and is arranged to gradually move away from the hole wall of the first mounting hole 11 from the end close to the first orifice 111 to the end far from the first orifice 111. Correspondingly, the first abutting surface 211 is also inclined.

[0068] Referring to Figure 6 and Figure 7 As shown, a first recess 221 is provided on the outer wall surface of the first terminal 2. The first fastener 13 includes an integrally formed first elastic arm 131 and a first clamping block 132. One end of the first elastic arm 131 close to the first orifice 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 towards the second orifice 112. The first clamping block 132 is arranged on the side of the first elastic arm 131 away from the hole wall of the first mounting hole 11.

[0069] After the first terminal 2 is inserted into the first mounting hole 11 from the first orifice 111, it can squeeze the first fastener 13. The deformation of the first elastic arm 131 drives the first clamping block 132 to move towards the hole wall of the first mounting hole 11 until the first clamping block 132 is clamped into the first recess 221. At this time, the first stop surface 151 abuts against the first abutting surface 211, and the first fastener 13 locks the first terminal 2 to prevent the first terminal 2 from moving towards the first orifice 111.

[0070] Specifically, two first fasteners 13 are symmetrically arranged in the first mounting hole 11 in a third direction to improve the locking stability of the first fastener 13 to the first terminal 2. More specifically, the two first fasteners 13 are respectively arranged in two gaps formed by the two first limiting blocks 15 and are connected to the first limiting blocks 15 to improve the structural strength of the first fastener 13.

[0071] More specifically, a first guiding surface is provided on the side of the first card block 132 facing the first orifice 111. The first guiding surface gradually moves away from the hole wall of the first mounting hole 11 from the side close to the first orifice 111 to the side far from the first orifice 111, so as to reduce the difficulty for the end of the first terminal 2 inserted into the first mounting hole 11 to move past the first card block 132 in the direction of the second orifice 112.

[0072] In this embodiment, in order to reduce the difficulty of inserting the first terminal 2 into the first mounting hole 11, the area of the first orifice 111 is larger than the maximum cross-sectional area of the first terminal 2. On this basis, the hybrid connector further includes an end cap 30. The end cap 30 is mounted on the insulating body 1 and is located on one side of the first orifice 111 of the first mounting hole 11. A wire passing hole for the first wire harness 10 to pass through is provided on the end cap 30, and the area of the wire passing hole is smaller than the area of the first orifice 111.

[0073] After the first terminal 2 connected to the first wire harness 10 is inserted into the first mounting hole 11, the end cap 30 is mounted on the insulating body 1, which can reduce the possibility of the first wire harness 10 shaking and improve the stability of the entire hybrid connector. Specifically, the end cap 30 is snap-connected to the insulating body 1 to facilitate the inspection and replacement of the first terminal 2.

[0074] Reference Figure 15 As shown, the first terminal 2 includes a front shielding shell 21, an inner conductor, a wire clamp, and a rear shielding shell 22. The rear end of the front shielding shell 21 is sleeved on the rear shielding shell 22 and crimped to the rear shielding shell 22. The inner conductor is located inside the front shielding shell 21 for electrically connecting the first docking terminal and the wire harness. The wire clamp is located inside the rear shielding shell 22 for fixing one end of the wire harness inside the rear shielding shell 22. The front shielding shell 21 is sequentially provided with a small-diameter section and a large-diameter section along the reverse direction of the first direction. The first abutting surface 211 is formed between the large-diameter section and the small-diameter section. The rear shielding shell 22 is arranged in a dumbbell shape. The first recess 221 is an annular groove formed on the rear shielding shell 22, and the annular groove is located outside the front shielding shell 21.

[0075] It can be understood that in other embodiments, the first recess 221 can be provided on the first elastic arm 131, while the first card block 132 is provided on the first terminal 2.

[0076] Reference Figure 12 and Figure 15As shown, in order to prevent the first terminal 2 from being inserted too deeply into the first mounting hole 11, which may cause damage to the first terminal 2 or the insulating body 1, in this embodiment, a guiding groove 152 extending in the first direction is further provided on the inner side surface of the first limiting block 15. One side of the guiding groove 152 close to the second hole opening 112 is closed. A guiding block 212 that is slidably engaged with the guiding groove 152 is provided on the outer wall surface of the first terminal 2. When the first terminal 2 is in a preset position within the first mounting hole 11, the guiding block 212 abuts against the groove wall at one end of the guiding groove 152 close to the second hole opening 112. Specifically, the guiding block 212 is provided on the outer wall surface of the large-diameter section.

[0077] Reference Figure 14 As shown, the first locking member 4 includes a socket portion 41 and a plugging portion 42. The socket portion 41 is connected to the plugging portion 42 and is located outside the plugging portion 42. A clamping space with an opening facing the direction of the first hole opening 111 is formed between the socket portion 41 and the plugging portion 42. The plugging portion 42 is inserted into the first mounting hole 11 from the second hole opening 112, and the socket portion 41 is sleeved outside the insulating body 1, so that the insulating body 1 is clamped within the clamping space.

[0078] The first locking member 4 is inserted into the first mounting hole 11 from the second hole opening 112. Reference Figure 6 and Figure 7 As shown, when the first locking member 4 is in the pre-installed position, the first locking member 4 and the first fastening member 13 are spaced apart in the first direction, and the first locking member 4 does not interfere with the deformation of the first fastening member 13, enabling the first terminal 2 to be inserted into the preset position of the first mounting hole 11 from the first hole opening 111; when the first locking member 4 is in the final locking position, the first fastening member 13 moves towards the first terminal 2 in the first direction, and the inner side of the plugging portion 42 abuts against the side of the first fastening member 13 facing away from the first terminal 2. Limited by the plugging portion 42, the first fastening member 13 no longer has the ability to deform towards the hole wall of the first mounting hole 11 and is always clamped to the first terminal 2, thereby maintaining the stability of the first terminal 2 when inserted into the first mounting hole 11. It should be emphasized that when the first locking member 4 is in the final locking position, the end face of the insulating body 1 abuts against the side of the clamping space far from the opening, restricting the first locking member 4 from continuing to move towards the first hole opening 111.

[0079] Specifically, a stepped surface 421 is formed at one end of the plugging portion 42 inserted into the first mounting hole 11. When the first locking member 4 is in the final locking position, the first fastening member 13 abuts against the stepped surface 421 to determine the final locking position of the first locking member 4, further reducing the possibility of the first locking member 4 being inserted excessively into the first mounting hole 11.

[0080] Meanwhile, on the side of the first locking member 4 facing the first terminal 2, a second stop surface 422 is further provided. The second stop surface 422 gradually moves away from the hole wall of the first mounting hole 11 from the end close to the first hole opening 111 towards the end far from the first hole opening 111. A second abutting surface 213 that cooperates 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 locking position, the second stop surface 422 abuts against the second abutting surface 213, and together with the first stop surface 151 and the first abutting surface 211, further restricts the first terminal 2 from moving towards the second hole opening 112.

[0081] More specifically, two second stop surfaces 422 are oppositely arranged on the inner side wall of the first locking member 4. Correspondingly, two second abutting surfaces 213 are also provided. The two second abutting surfaces 213 are also formed between the small-diameter section and the large-diameter section of the front shielding shell 21, that is, the second abutting surface 213 and the first abutting surface 211 together form a conical surface connecting the large-diameter section and the small-diameter section.

[0082] Reference Figure 5 and Figure 9 As shown in the figure, in order to facilitate observing whether the first locking member 4 is in the pre-assembled position or the final locking position, and to improve the stability when the first locking member 4 is assembled on the insulating body 1, a first positioning block 17 is provided on one of the first locking member 4 and the insulating body 1, and a first slot hole 43 that is snap-fitted with the first positioning block 17 is provided on the other. Two first slot holes 43 are spaced along the first direction. When the first positioning block 17 is limited in the first slot hole 43 that is far from the second hole opening 112, the first locking member 4 is in the pre-assembled position. When the first positioning block 17 is limited in the first slot hole 43 that is close to the second hole opening 112, the first locking member 4 is in the final locking position.

[0083] Exemplarily, the first positioning block 17 is provided on the insulating body 1, and the first slot hole 43 is provided on the first locking member 4. Specifically, the cross-section of the first positioning block 17 is set as an equilateral trapezoid or an equilateral triangle with a chamfer to reduce the difficulty of the first positioning block 17 entering and exiting the first slot hole 43.

[0084] Reference Figure 14 As shown in the figure, in order to reduce the difficulty of the first locking member 4 detaching from the insulating body 1, a relief notch 411 is formed on the socket part 41. The relief notch 411 extends along the first direction to the end face of the socket part 41 close to the first terminal 2. When disassembling the first locking member 4, applying a force to the socket part 41 along the second direction away from the insulating body 1 can make the first positioning block 17 disengage from the first slot hole 43.

[0085] Reference Figure 8As shown, the second mounting hole 12 has a third orifice 121 and a fourth orifice 122 disposed opposite to each other in the first direction. The third orifice 121 and the first orifice 111 are on the same side of the insulating body 1. A third stop surface 161 is provided on the side of the second mounting hole 12 near the fourth orifice 122. The third stop surface 161 can abut against the third abutting surface 33 on the second terminal 3, thereby restricting the second terminal 3 from further moving in the direction of the fourth orifice 122 and inserting the second terminal 3 to a preset position in the second mounting hole 12.

[0086] Specifically, a ring-shaped second limiting block 16 is provided on the side of the second mounting hole 12 near the fourth orifice 122. The third stop surface 161 is formed on the side of the second limiting block 16 facing away from the fourth orifice 122 and is set as a conical surface, which gradually expands from the end close to the fourth orifice 122 to the end away from the fourth orifice 122. A conical third abutting surface 33 is formed on the outer wall surface of the second terminal 3. When the third abutting surface 33 abuts against the third stop surface 161, the second terminal 3 is inserted to the preset position in the second mounting hole 12.

[0087] Reference Figure 8 and Figure 17 As shown, a second recess 31 is provided on the outer wall surface of the second terminal 3. The second fastening member 14 includes an integrally formed second elastic arm 141 and a second locking block 142. One end of the second elastic arm 141 near the third orifice 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 in the direction of the fourth orifice 122. The second locking block 142 is provided on the side of the second elastic arm 141 away from the hole wall of the second mounting hole 12. Specifically, the second recess 31 is a groove formed on the outer wall surface of the second terminal 3.

[0088] After the second terminal 3 is inserted into the second mounting hole 12 from the third orifice 121, it can squeeze the second fastening member 14. The deformation of the second elastic arm 141 drives the second locking block 142 to move towards the hole wall of the second mounting hole 12 until the second locking block 142 is snapped into the second recess 31. At this time, the third stop surface 161 abuts against the third abutting surface 33, and the second terminal 3 is locked with the cooperation of the second fastening member 14.

[0089] In this embodiment, a second guiding surface is further provided on the side of the second locking block 142 facing the third orifice 121. The second guiding surface gradually inclines from the side close to the third orifice 121 towards the center direction of the second mounting hole 12 to reduce the difficulty for the end of the second terminal 3 inserted into the second mounting hole 12 to move past the second locking block 142 in the direction of the fourth orifice 122.

[0090] It can be understood that the positions of the second recess 31 and the second locking block 142 can be interchanged between the second elastic arm 141 and the second terminal 3.

[0091] The second locking member 5 is inserted into the insulating body 1 in the reverse direction along the third direction from the side away from the first terminal 2. Figure 10 , Figure 11 and Figure 16 As shown, the second locking member 5 is provided with an avoidance groove 513 which is arranged to penetrate along the first direction. The avoidance groove 513 on the second locking member 5 in the pre-installed position is opposite to the second terminal 3 to allow the second terminal 3 to be inserted into or disengaged from the second mounting hole 12, while the avoidance groove 513 on the second locking member 5 in the final locking position is offset from the second terminal 3, and the second terminal 3 is locked in the second mounting hole 12.

[0092] In order to avoid the second locking member 5 when the second locking member 5 moves along the third direction, the second terminal 3 is provided with a clearance groove 32. Based on the premise that the second terminals 3 are arranged in a row along the third direction, a plurality of clearance grooves 32 located on each second terminal 3 are arranged along the third direction, and the second locking member 5 is provided with the same number of avoidance grooves 513 as the number of the second terminals 3.

[0093] In other embodiments, the second locking member 5 may also lock the second terminal 3 in a snap-fit ​​manner.

[0094] Taking the case where two rows of second terminals 3 are symmetrically arranged along the second direction, continue to refer to Figure 16 As shown, the second locking member 5 includes a connecting portion 52 and two cantilever portions 51, the connecting portion 52 extends along the second direction, and the two cantilever portions 51 are respectively arranged on opposite sides of the connecting portion 52 along the second direction and are perpendicular to the connecting portion 52, so that the second locking member 5 is approximately U-shaped. Based on the setting of the avoidance groove 513, the avoidance groove 513 is arranged on the cantilever portion 51. When the cantilever portion 51 is inserted into the insulating body 1 until the second terminal 3 is in the pre-installed position, each avoidance groove 513 on the cantilever portion 51 corresponds to each second terminal 3 one by one, and does not affect the second terminal 3 from being inserted into the second mounting hole 12 or being separated from the second mounting hole 12. When the cantilever portion 51 continues to be inserted into the insulating body 1 until the second terminal 3 is in the final locking position, each avoidance groove 513 is staggered with each second terminal 3, limiting the second terminal 3 from moving toward the fourth opening 122.

[0095] refer to Figure 13 As shown, in order to provide guidance for the second terminal 3 when the second terminal 3 is inserted into the insulating body 1, two fixing grooves 18 extending along the third direction are provided on the outer wall of the insulating body 1, and the two fixing grooves 18 are respectively connected to the two rows of second mounting holes 12, and the two cantilever portions 51 are respectively inserted into the insulating body 1 along the two fixing grooves 18.

[0096] Further, in order to facilitate observing whether the second locking member 5 is in the pre-assembled position or the final locking position, and to improve the stability when the second locking member 5 is assembled on the insulating body 1, a second positioning block 514 is provided on one of the second locking member 5 and the insulating body 1, and a second slot 19 that is snap-fitted with the second positioning block 514 is provided on the other. Two second slots 19 are spaced along the third direction. When the second positioning block 514 is limited to one of the two second slots 19 that is away from the first terminal 2, the second locking member 5 is in the pre-assembled position. When the second positioning block 514 is limited to one of the two second slots 19 that is close to the first terminal 2, the second locking member 5 is in the final locking position.

[0097] Exemplarily, the second positioning block 514 is provided on the cantilever portion 51 of the second locking member 5, and the second positioning blocks 514 are provided on both cantilever portions 51. The corresponding second slots 19 for the second positioning blocks 514 are respectively provided on the side walls of the two fixing slots 18.

[0098] In order to reduce the difficulty of the second positioning block 514 entering the second slot 19, the second positioning block 514 is designed in a triangular shape. At the same time, a strip-shaped relief hole 515 extending along the third direction is also provided on the second locking member 5. When the second positioning block 514 enters the second slot 19, the relief hole 515 provides a relief space for the deformation of the second locking member 5. Specifically, the cantilever portion 51 further includes a mounting portion 512 and a locking portion 511 that are arranged in an L shape. The mounting portion 512 and the locking portion 511 are both connected to the connecting portion 52. The mounting portion 512 can slide in the fixing slot 18, and the locking portion 511 is inserted into the second mounting hole 12. The second positioning block 514 and the relief groove 513 are respectively provided on the mounting portion 512 and the locking portion 511, and a strip-shaped relief hole 515 extending along the third direction is provided in the mounting portion 512 to enhance the plasticity of the second locking member 5, reduce the difficulty of the second locking member 5 switching between the pre-assembled position and the final locking position, and at the same time reduce the material cost of manufacturing the second locking member 5.

[0099] More specifically, in order to reduce the difficulty of disassembling the second locking member 5, a force application groove 521 for facilitating force application is further provided on the connecting portion 52, and the force application groove 521 extends along the reverse direction of the first direction to the surface of the connecting portion 52.

[0100] Reference Figure 3 and Figure 8 As shown, the hybrid connector further includes a first sealing ring 8. The first sealing ring 8 is provided at the fourth orifice 122 of the second mounting hole 12 and is provided with a through hole 84 for the second cable 20 to pass through. The first sealing ring 8 can seal the gap between the fourth orifice 122 and the second terminal 3, playing a role in dust prevention and waterproofing.

[0101] Reference Figure 24As shown, on the premise that there are multiple second terminals 3, the first sealing ring 8 adopts a group sealing ring, and a plurality of through holes 84 corresponding to the plurality of second mounting holes 12 one by one are provided on the group sealing ring. Specifically, an installation groove 110 communicating with each second mounting hole 12 is formed on the insulating main body 1, and the first sealing ring 8 is installed in the installation groove 110. In order to improve the sealing performance of the first sealing ring 8, the first sealing ring 8 includes a sealing main body 83 and a plurality of first annular protrusions 81 spaced along the first direction on the outer wall surface of the sealing main body 83. The first annular protrusions 81 are annularly arranged to increase the contact area with the groove side wall of the installation groove 110 and improve the sealing performance. At the same time, a plurality of second annular protrusions 82 are spaced along the first direction on the hole wall of each through hole 84. The second annular protrusions 82 are also annularly arranged to increase the contact area with the second cable 20 and improve the sealing performance.

[0102] Reference Figures 1 - 3 As shown, the hybrid connector further includes a housing 6. The housing 6 has a cavity with one side open along the first direction. The insulating main body 1 is located in the cavity of the housing 6, and the housing 6 is used to protect the insulating main body 1. At the position corresponding to the connecting portion 52 of the second locking member 5 on the housing 6, an operation hole 61 communicating with the cavity of the housing 6 is provided. A force towards the first terminal 2 can be applied to the second locking member 5 through the operation hole 61 to switch the second locking member 5 from the pre-installed position to the final locking position.

[0103] It should be emphasized that the length of the operation hole 61 along the second direction is smaller than the length of the connecting portion 52 along the second direction. In other words, the positive projection area of the second locking member 5 towards the operation hole 61 is larger than the area of the operation hole 61 to prevent the second locking member 5 from detaching from the insulating main body 1 or being squeezed into the final locking position through the operation hole 61 during transportation.

[0104] Specifically, referring to Figure 22 and Figure 23 As shown, a third slot hole 62 is provided on the housing 6, and a third positioning block 120 engaged with the third slot hole 62 is provided on the insulating main body 1. The third positioning block 120 is limited in the third slot hole 62 to realize the detachable fixed connection between the insulating main body 1 and the housing 6. More specifically, two third slot holes 62 are symmetrically arranged on the housing 6 along the third direction, and two third positioning blocks 120 are also provided to improve the connection stability between the housing 6 and the insulating main body 1. And an inclined third guiding surface is formed at one end of the third positioning block 120 facing away from the slot opening of the housing 6 to reduce the difficulty of the third positioning block 120 being inserted into the third slot hole 62. Of course, the third slot hole 62 can also be provided on the insulating main body 1, and the third positioning block 120 is provided on the housing 6.

[0105] Reference Figure 16As shown, both the first orifice 111 and the third orifice 121 on the insulating body 1 face the closed end of the housing 6, and a plurality of through holes 63 for the first cable 10 and the second cable 20 to pass through are respectively formed at positions corresponding to the first mounting hole 11 and the second mounting hole 12 at the closed end of the housing 6. The docking connector can be electrically connected to the hybrid connector from the open end of the housing 6.

[0106] There is a gap between the end of the insulating body 1 close to the open end of the housing 6 and the housing 6 for inserting the docking connector. In order to lock the docking connector to the hybrid connector, the housing 6 further includes a third fastener 64 provided on the inner wall of the housing 6, and the third fastener 64 is engaged with the hybrid connector.

[0107] Specifically, referring to Figure 19 and Figure 22 As shown, the third fastener 64 includes a third elastic arm 641 and a third recess 643. The third elastic arm 641 is connected to the inner wall of the housing 6, and the third recess 643 is provided at one end of the third elastic arm 641 extending towards the notch. A third locking block is formed on the docking connector and can be engaged with the third recess 643 to lock the docking connector.

[0108] More specifically, two third elastic arms 641 are arranged at intervals along the third direction, and the two third elastic arms 641 are connected by a connecting rod 642 to form the above-mentioned third recess 643 between the two third elastic arms 641. The third locking block is engaged with the third recess 643 and abuts against the connecting rod 642.

[0109] Referring to Figure 19 and Figure 23 As shown, a jack 65 for the third fastener 64 to extend into the inner cavity of the housing 6 is formed at the closed end of the housing 6. The jack 65 is communicated with the inner cavity of the housing 6. The third elastic arm 641 is connected to the hole wall of the jack 65 through a fulcrum, and one end of the third elastic arm 641 connected to the connecting rod 642 extends into the inner cavity of the housing 6 from the jack 65, and the other end is located outside the housing 6. When unlocking the locking of the third fastener 64 to the docking connector, only need to press one end of the third elastic arm 641 located outside the housing 6.

[0110] In order to further improve the stability between the hybrid connector and the docking connector, the hybrid connector further includes a third locking member 7. The third locking member 7 also has a pre-installed position and a final locking position. The third locking member 7 in the pre-installed position allows the docking connector to be inserted into a preset position inside the housing 6, and the third locking member 7 in the final locking position enables the third fastener 64 to maintain the locking of the docking connector.

[0111] Continuing to refer to Figure 19 and Figure 20As shown, the third locking member 7 is inserted into the housing 6 from the closed end of the housing 6 along the first direction. The third locking member 7 includes a locking arm 71. The end of the locking arm 71 of the third locking member 7 in the pre-assembled position is located on the side of the connecting rod 642 facing away from the open end of the housing 6. The locking arm 71 on the third locking member 7 in the final locking position abuts against the outside of the third fastener 64, restricting the third fastener 64 from moving away from the third locking block. Specifically, a locking groove 72 is provided on the locking arm 71, and the connecting rod 642 can be clamped in the locking groove 72 and abut against the bottom of the locking groove 72.

[0112] Reference Figure 21 and Figure 23 As shown, in order to improve the stability of the third locking member 7 assembled on the housing 6, a fourth positioning block 66 is provided on one of the third locking member 7 and the housing 6, and a fourth slot hole 731 that is snap-fitted with the fourth positioning block 66 is provided on the other. Two fourth slot holes 731 are provided at intervals along the first direction. When the fourth positioning block 66 is clamped in one of the two fourth slot holes 731 that is far from the open end of the housing 6, the fourth locking member is in the pre-assembled position; when the fourth positioning block 66 is clamped in one of the two fourth slot holes 731 that is close to the open end of the housing 6, the fourth locking member is in the final locking position.

[0113] Exemplarily, the third slot hole 62 is provided on the third locking member 7, and the third positioning block 120 is provided on the housing 6, specifically on the inner wall of the insertion hole 65. Specifically, the third locking member 7 includes two positioning arms 73 that are provided at intervals along the third direction on opposite sides of the locking arm 71. Both positioning arms 73 are connected to the locking arm 71 and inserted into the insertion hole 65, and the third slot hole 62 is opened on the positioning arm 73. At the same time, in order to reduce the difficulty of disassembling and assembling the third locking member 7, the third locking member 7 further includes a push-pull plate 74, and the push-pull plate 74 connects the locking arm 71 and the end of the positioning arm 73 outside the housing 6.

[0114] Continuing to refer to Figure 23 As shown, in order to facilitate applying force to the third fastener 64 so that the docking connector is separated from the hybrid connector, a U-shaped connecting block 644 is connected to the ends of the two third elastic arms 641 that are far from the connecting rod 642, that is, the ends of the two third elastic arms 641 located outside the housing 6. The two third elastic arms 641 are respectively connected to both ends of the connecting block 644. By applying pressure to the connecting block 644, the third elastic arms 641 can move away from the third locking block under the lever action, so that the third elastic arms 641 are separated from the third locking block. The locking arm 71 of the third locking member 7 passes through the connecting block 644 and then is inserted into the housing 6, so the unlocking of the third locking member 7 and the unlocking of the third fastener 64 do not interfere with each other.

[0115] Reference Figure 3 and Figure 19As shown in the figure, the hybrid connector further includes a second sealing ring 9. The second sealing ring 9 is sleeved on the insulating body 1 and located in the gap formed between the insulating body 1 and the outer shell 6. The second sealing ring 9 can be in contact with the docking connector inserted into the outer shell 6 to achieve the sealing between the docking connector and the insulating body 1, further improving the waterproof and dustproof performance of the connector assembly.

[0116] Specifically, a plurality of third annular protrusions 91 and fourth annular protrusions 92 are respectively arranged at intervals along the first direction on the inner peripheral wall and the outer peripheral wall of the second sealing ring 9 to increase the contact area between the second sealing ring 9 and the insulating body 1 and the docking connector, and improve the sealing performance.

[0117] When assembling the above hybrid connector, first insert the injection-molded second locking member 5 into the insulating body 1 along the third direction to make the second locking member 5 in the pre-installed position. Then, sleeve the second sealing ring 9 on the insulating body 1. At the same time, insert the injection-molded first locking member 4 into the first mounting hole 11 along the first direction to make the first locking member 4 in the pre-installed position. Then, install the first sealing ring 8 in the installation groove 110. Then, sleeve the outer shell 6 on the insulating body 1, insert the third locking member 7 into the outer shell 6, and finally insert the first terminal 2 and the second terminal 3. When necessary, push the first locking member 4 and the second locking member 5 to the final locking position.

[0118] When it is necessary to remove the first terminal 2 from the first mounting hole 11 to replace it with a new first terminal 2, the first locking member 4 can be first removed from the insulating body 1 with the help of a tool, and then a tool is inserted into the first mounting hole 11 and pried against the inner wall of the first mounting hole 11 in the direction of the hole wall, so that the first terminal 2 can be separated from the insulating body 1, effectively reducing the fault repair cost. When it is necessary to remove the second terminal 3 from the second mounting hole 12 to replace it with a new second terminal 3, a force away from the insulating body 1 along the third direction can be applied to the second locking member 5 through the force application groove 521, so as to remove the second locking member 5 from the insulating body 1. Then, a tool is extended into the second mounting hole 12 and a force away from the second terminal 3 is applied to the second fastening member 14, so that the second fastening member 14 is separated from the second terminal 3, and the second terminal 3 can be separated from the insulating body 1. When it is necessary to separate the docking connector from the hybrid connector, pressure is applied to the push-pull plate 74 of the third locking member 7 to make the end of the third locking member 7 engaged with the third fastening member 64 separated from the third fastening member 64. Then, the third locking member 7 is pulled out of the outer shell 6, and pressure is applied to the connecting block 644 of the third fastening member 64 to make the end of the third fastening member 64 engaged with the docking connector separated from the docking connector, and the docking connector can be pulled out of the outer shell 6.
