[0032] The present application provides a connector and a connector assembly, which are described in detail below. It should be noted that the order in which the following embodiments are described does not limit the preferred order of the embodiments of the present application. In addition, in the following embodiments, the description of each embodiment has its own emphasis. For parts not described in detail in one embodiment, please refer to the relevant description of other embodiments.

[0033] Reference Figure 1 and Figure 2 The connector provided in this application includes a first shell 1 and a fixing member 2. The first shell 1 has a first portion and a second portion extending along its extension direction. The first portion is provided with a wire hole 11 extending along its extension direction, and the second portion is provided with a terminal hole 12 extending along its extension direction. The wire hole 11 and the terminal hole 12 are not connected to each other. The wire hole 11 is used for passing the cable, and the terminal hole 12 is used for passing the power terminal. The first shell 1 has a fixing groove 13 on the outer wall of the second portion. The fixing groove 13 passes through the outer wall and is connected to the terminal hole 12. The fixing member 2 is arranged in the fixing groove 13 to press the power terminal into the terminal hole 12, thereby fixing the power terminal installed in the terminal hole 12 and preventing the power terminal from falling out of the terminal hole 12, which is beneficial to improving the connection reliability between the two and thereby ensuring the stability of signal transmission. In addition, the present application integrates the power terminal and the cable on the same first shell 1, so that the volume of the connector can be greatly reduced.

[0034] In some embodiments, the connector is a lidar connector.

[0035] Based on the above embodiment, the terminal holes 12 have multiple mutually non-interpenetrating structures, the above-mentioned fixing member 2 is U-shaped, and the fixing groove 13 is U-shaped. The fixing groove 13 extends circumferentially along the outer wall of the first shell 1 in the second part to cover and connect all the terminal holes 12, so that all power terminals installed in the terminal holes 12 can be fixed by assembling the U-shaped fixing member 2 at one time.

[0036] For example, the connector has a first direction X, a second direction Y, and a third direction Z, all perpendicular to each other. The connector has six terminal holes 12 arranged in an array. Specifically, there are two rows in the first direction, with each row having three terminals in the second direction. The third direction Z is the direction in which the first housing 1 extends, i.e., the direction in which the wire holes 11 and the terminal holes 12 extend.

[0037] Based on the above embodiment, refer to Figure 2 、 Figure 3 and Figure 4 The fixing member 2 has two fixing arms 21 disposed opposite each other, and a connecting arm 22 connected to the ends of the two fixing arms 21. Each fixing arm 21 is provided with a clamping portion 211 on at least one side of the extension direction (the third direction Z). The fixing groove 13 is provided with an adapting portion 131 at a corresponding position, and the clamping portion 211 is adapted to the adapting portion 131. By way of example, the drawings of this application illustrate an embodiment in which the clamping portion 211 is a clamping protrusion and a corresponding clamping groove is provided on the groove wall of the fixing groove 13. Of course, in other embodiments, the positions of the clamping protrusion and the clamping groove may be interchanged.

[0038] In order to facilitate the snap-fitting between the snap-fitting portion 211 of the fixed arm 21 and the adapting portion 131 of the fixed slot 13, each of the above-mentioned fixed arms 21 extends along the first direction X, and the two fixed arms 21 are arranged at intervals along the second direction Y. Each of the fixed arms 21 is provided with a clearance groove 212, and the clearance groove 212 extends along the second direction Y, so that when the snap-fitting portion 211 of the fixed arm 21 and the adapting portion 131 of the fixed slot 13 are installed, the portions of the fixed arm 21 located on both sides of the clearance groove 212 can be deformed toward the clearance groove 212, thereby facilitating the snap-fitting between the two.

[0039] Reference Figure 1 and 5 The connector also includes a first sealing ring 3 and a second sealing ring 4. The first sealing ring 3 is sleeved on the outer periphery of the power terminal and seals the power terminal and the hole wall of the terminal hole 12. The second sealing ring 4 is sleeved on the outer periphery of the cable and seals the cable and the hole wall of the wire hole 11, thereby realizing the sealing function of the connector to prevent external foreign matter from entering the above-mentioned wire hole 11 or terminal hole 12, causing electrical failure inside the connector.

[0040] Based on the above embodiment, the first housing 1 has a first end 15 and a second end 16 disposed opposite each other along its extension direction, wherein the first sealing ring 3 is disposed near the first end 15, and the fixing member 2 is disposed near the second end 16. It is understood that when the first sealing ring 3 seals the power terminal and the wall of the terminal hole 12, a fixed connection between the two can also be achieved. The present application improves the connection reliability of the power terminal by arranging the first sealing ring 3 and the fixing member 2 at intervals along the extension path of the power terminal.

[0041] Similarly, in order to ensure the connection reliability of the cable, the first shell 1 has a first end 15 and a second end 16 arranged opposite to each other along its extension direction, and the connector also includes a clamping member 5, and the second sealing ring 4 is arranged near the first end 15, and the clamping member 5 is arranged in the wire threading hole 11 and near the second end 16, and the clamping member 5 presses the cable to the wire threading hole 11.

[0042] In some embodiments, reference Figure 6 and Figure 7 A retaining wall structure 17 is provided in the first shell 1, and the retaining wall structure 17 is used to isolate the wire threading hole 11 and the terminal hole 12. A receiving groove 171 is provided on the retaining wall structure 17, and the receiving groove 171 is recessed from the end surface of the retaining wall structure 17 located at the second end 16 toward the first end 15, and is connected with the wire threading hole 11. A clamping claw 172 is provided at the bottom of the receiving groove 171, and the clamping claw 172 extends along the through-direction of the wire threading hole 11 and does not contact the groove wall of the receiving groove 171. At least part of the clamping member 5 is inserted into the side of the clamping claw 172 away from the central axis of the wire threading hole 11 to apply a force toward the central axis to the clamping claw 172, so that the clamping claw 172 can clamp or compress the cable.

[0043] For example, the clamping claw 172 has a connecting end and a clamping end that are oppositely disposed. The connecting end is connected to the bottom of the receiving groove 171, and the clamping end is used to clamp or compress the cable. The remaining portion of the clamping claw 172, except for the connecting end, is suspended within the receiving groove 171, thereby ensuring that the suspended portion of the clamping claw 172 can move toward or away from the central axis of the threading hole 11. In addition, the clamping claw 172 has a protrusion on the side facing away from the compression member 5, which is close to the clamping end to better secure the cable within the threading hole 11.

[0044] In particular, for the embodiment in which a retaining wall structure 17 is provided in the first shell 1 , the first portion and the second portion of the first shell 1 can be distinguished by the retaining wall structure 17 .

[0045] In some embodiments of this application, please refer to Figure 2 and Figure 3 The connector also includes a third sealing ring 6, which is sleeved on the outer periphery of the first shell 1, or the third sealing ring 6 is sleeved on the outer periphery of the first shell 1 and forms an integral structure therewith. The third sealing ring 6 is sleeved on the outer periphery of the first shell 1, thereby achieving a sealed connection with the adapter connector. The third sealing ring 6 can be integrally formed with the first shell 1 through a hot pressing process, which can not only ensure that there is sufficient pressure for the third sealing ring 6 to perform its sealing function, but also ensure that the assembly position of the third sealing ring 6 remains unchanged when subjected to force. According to experimental verification, the above arrangement can improve the waterproof level of the connector from the original IP67 to IP69K. The integral molding of the third sealing ring 6 and the first shell 1 greatly increases the holding force for the installation of the third sealing ring 6, providing a higher sealing interference, thereby improving the sealing level.

[0046] For example, an annular groove 14 is provided on the outer periphery of the first housing 1. The annular groove 14 surrounds the outer periphery of the first housing 1 to facilitate the installation and positioning of the third sealing ring 6. Furthermore, when the connector and the mating connector are assembled, a certain extrusion force can be applied to the third sealing ring 6, so that the axial end surface of the third sealing ring 6 and the groove wall of the annular groove 14 can be tightly fitted, thereby improving the sealing performance of both.

[0047] The annular groove 14 can be formed by thinning the wall of the first shell 1. Alternatively, two annular baffles can be provided on the outer periphery of the first shell 1, and the two annular baffles are spaced apart along the extension direction of the first shell 1. In the latter technical solution, the annular baffles can be regarded as reinforcing ribs to a certain extent, which is conducive to improving the structural strength of the first shell 1.

[0048] In order to improve the structural strength of the connector, such as Figure 8 As shown, the above-mentioned connector also includes a second shell 7 and a mating connector 8. At least a portion of the first shell 1 is arranged in the second shell 7 and connected to the second shell 7. The mating connector 8 is used to connect the second shell 7 and the adapter connector to achieve a fixed connection between the connector and the adapter connector, ensuring that the connection between the two is more stable and reliable.

[0049] The first shell 1 is usually an insulating member or a shielding member to isolate the signals of the cable and the power terminal on their respective signal transmission paths to ensure the signal transmission effect. For the embodiment in which the first shell 1 has a first end 15 and a second end 16 arranged opposite to each other along its extension direction, at least a portion of the first shell 1 close to the first end 15 is accommodated in the second shell 7, and a portion close to the second end 16 is exposed to the outside of the second shell 7, so as to facilitate connection with the adapter connector. The end of the second shell 7 close to the second end 16 covers at least a portion of the fixing member 2. A through hole corresponding to and connected to the wire threading hole 11, and a jack corresponding to and connected to the terminal hole 12 are provided on the side wall of the second shell 7 facing the first end 15.

[0050] In some embodiments of the present application, the present application also provides a connector including a first shell 1, a fixing member 2, a cable and a power terminal, the first shell 1 having a first part and a second part along its extension direction, the first part having a wire threading hole 11 extending along its extension direction, the second part having a terminal hole 12 extending along its extension direction, the wire threading hole 11 and the terminal hole 12 being not connected to each other, the cable being passed through the wire threading hole 11, the power terminal being passed through the terminal hole 12, the first shell 1 having a fixing groove 13 on the outer wall of the second part, the fixing groove 13 passing through the outer wall and being connected to the terminal hole 12, the fixing member 2 being arranged in the fixing groove 13 to press the power terminal tightly into the terminal hole 12, thereby fixing the power terminal installed in the terminal hole 12 and preventing the power terminal from falling off from the terminal hole 12, which is beneficial to improving the connection reliability between the two and thereby ensuring the stability of signal transmission.

[0051] In other embodiments, the present application further provides a connector assembly comprising the connector described in any of the above technical solutions and an adaptor connector, wherein the adaptor connector is adapted to and electrically connected to the connector. Because the connector in this connector assembly and the above connector have the same structure, they can solve the same technical problems and achieve the same technical effects.

[0052] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0053] The above is only a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in the present application, which should be included in the scope of protection of the present application.
