[0019] like Figures 1-9 The illustrated embodiment A vehicle-mounted lidar rear housing connector includes a housing 1, a connector body 2, a power supply assembly 3, and an inner cover 4. The housing 1 has a power external interface 11 and a signal external interface 12 on its outer side. The power supply assembly 3 includes a wire-end power terminal 31 and a board-end power terminal 32, with the wire-end power terminal 31 extending into the power external interface 11. The connector body 2 is fixed to the housing 1, and the wire-end signal terminal of the connector body 2 extends into the signal external interface 12. The inner ends of the connector body 2 and the board-end power terminal 32 are fitted together within the inner cover 4. The inner cover 4 integrates a power internal interface 41 and a signal internal interface 42, with the board-end power terminal 32 extending into the power internal interface 41 and the board-end signal terminal of the connector body 2 extending into the signal internal interface 42.

[0020] In this embodiment, the outer shell 1 is a plastic shell, and the connector body 2 is a coaxial connector.

[0021] For waterproofing, in this embodiment, a second sealing ring 9 is provided around the connector body 2 and the power assembly 3. The second sealing ring 9 is fixed in the annular groove 13 on the rear side of the outer shell 1.

[0022] The above are the same structural designs in the two embodiments of this application. The following are the different structural designs in the two embodiments of this application.

[0023] Example 1 The line-end power terminal 31 and the board-end power terminal 32 are two sets of power pins that are separately set and electrically connected through the PCB board 5. Multiple line-end power terminals 31 and board-end power terminals 32 are respectively soldered and fixed to the upper and lower sides of the PCB board 5.

[0024] To ensure waterproofing, a sealing ring 6 is provided between the upper side of the PCB board 5 and the outer casing 1. The sealing ring 6 is clamped between the inner periphery of the power connector 11 and the PCB board 5. During assembly, the multiple connecting holes on the PCB board 5 are connected to the multiple positioning posts on the outer casing 1 and then riveted in place. The sealing ring 6 is pressed between the two, achieving a waterproof seal, eliminating the need for glue, simplifying the process, and reducing costs.

[0025] Further waterproofing: An interface waterproofing layer (not shown in the figure) can also be provided on the upper surface of PCB board 5.

[0026] For ease of assembly, Embodiment 1 also includes a power insulator 7.

[0027] The PCB board 5 has a through hole 50. The plug end of the board-end power terminal 32 is built into the power insulator 7. The other end of the board-end power terminal 32 extends outside the terminal channel 72. The power insulator 7 has a protruding positioning post 71. When the positioning post 71 is inserted into the through hole 50 on the PCB board 5, the board-end power terminal 32 also passes through the corresponding soldering hole, thus positioning the board-end power terminal 32 on the PCB board 5. The board-end power terminal 32 is positioned on the PCB board 5 by inserting the power insulator 7 into the through hole 50, and then the board-end power terminal 32 is fixed to the PCB board 5 by soldering. This structure is simple, the process is mature, and the overall cost is low.

[0028] The board-end power terminal 32 and the power insulator 7 can be integrally molded by overmolding or assembled separately. When assembling separately, the power insulator 7 is injection molded first, and then the board-end power terminal 32 is inserted into the terminal channel 72 of the power insulator 7.

[0029] To enhance connection stability, the power terminal 32 at the board end is provided with barbs 321 to prevent it from detaching from the terminal channel 72.

[0030] The inner cover 4 is snapped together with the outer shell 1. The specific structure is as follows: the outer wall of the inner cover 4 is designed with two downward-extending buckles 44. The downward-extending buckles 44 are inserted into the two spring buckles 15 of the outer shell 1 and then fastened. The spring buckles 15 are provided with locking holes for the buckles 44 to slide into and engage.

[0031] To enhance connection stability, the power insulator 7 has recessed slots 73 on its two opposite outer sides. The power insulator 7 is fitted inside the inner cover 4. Square holes are opened on the two opposite side walls of the inner cover 4. The lower edge of the two square holes has upward-extending buckles 44. When the downward-extending buckles 44 are engaged with the two spring buckles 15 of the outer shell 1, the upward-extending buckles 44 are engaged with the recessed slots 73 and then engaged.

[0032] Example 2 The wire-end power terminal 31 and the board-end power terminal 32 are integrally molded power PIN pins. The front part of the PIN pin is bent upward to form the wire-end power terminal 31, and the rear part is bent downward to form the board-end power terminal 32. Multiple power PIN pins are encapsulated and fixed inside the power insulator 8. The power PIN pin assembly adopts an integral injection molding process, resulting in a stable structure.

[0033] The four connecting holes on the power insulator 8 are connected to the four positioning posts on the outer shell 1 and then fixed by heat riveting. The power PIN pin assembly and the outer shell 1 are assembled and positioned at four points and fixed by heat riveting; compared with the secondary encapsulation process of the power insulator 7 in Embodiment 1, the cost is lower, the manufacturing process is simpler, and the efficiency is higher.

[0034] To prevent water damage, apply 100 gluing to seal the base of the power terminal 31 at the wire end and the power insulator 28.

[0035] In this second embodiment, the inner cover 4 is snapped together with the outer shell 1. The specific structure is as follows: the outer wall of the inner cover 4 is designed with four inverted buckles 44, which are inserted into and fastened with the four spring buckles 15 of the outer shell 1. The spring buckles 15 are provided with locking holes for the inverted buckles 44 to slide into and engage.

[0036] To facilitate quick assembly, the inner cover 4 has upwardly extending protrusions 43, with multiple protrusions 43 distributed around the perimeter. The outer shell 1 has corresponding outer shell grooves 14, and the multiple protrusions 43 are inserted into the outer shell grooves 14. During assembly, the inner cover 4 is designed with four protrusions 43, which are inserted into the outer shell grooves 14 to position the inner cover 4 and the outer shell 1 and to enhance the inner cover 4's resistance to lateral pressure.

[0037] This embodiment provides a rear housing connector for an on-board LiDAR, and the assembly includes at least the following steps: Step 1: Assemble the connector body 2 and the power supply assembly 3. Step 2: Insert the connector body 2 and the power supply assembly 3 into the power interface 11 and signal interface 12 on the outer shell 1 from the inside out, respectively. Step 3: Secure the power supply assembly 3 with heat riveting. Step 4: Insert the inner cover 4 into the four spring clips 15 of the outer shell 1 and fasten them together.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
