[0002] Electrical connectors, as key components in electronic devices, are widely used in various fields such as electronics, electrical appliances, and instrumentation. They act as a connecting bridge, establishing a stable connection at points of blockage within a circuit or between independent circuits, thereby ensuring the smooth transmission of current or signals.
[0003] As electronic devices become increasingly miniaturized and integrated, the corresponding connectors are often required to achieve multifunctional integration within a limited space. For example, with the widespread application of LiDAR in autonomous vehicles, LiDAR technology is developing towards solid-state and miniaturization, requiring the connectors to integrate power supply and control signal transmission while simultaneously enabling high-speed signal transmission. However, traditional LiDAR connectors can only achieve the single function of signal transmission; they cannot achieve high-frequency signal transmission and require an external power supply, making it difficult to meet the demands for high integration, high reliability, and high-speed signal transmission.

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0041] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.
[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0043] Please see Figures 1 to 10 , Figures 1 to 10 The lidar connector shown is a board-end connector, meaning one end of the lidar connector connects to the circuit board of the electronic device, and the other end connects to the mating lidar connector. It should be understood that this board-end connector should not be used to limit the scope of protection of the lidar connector of this utility model; for example, the technical solution protected by this utility model can also be applied to wire-end connectors.
[0044] Please see Figure 1 and Figure 2In the illustrated embodiment, the lidar connector includes an insulating body 100, a signal connection component 200 and a power connection component 300 disposed on the insulating body 100, a shielding component 400 for isolating and shielding the signal connection component 200 and the power connection component 300, and a grounding component 500. The signal connection component 200 and the power connection component 300 can be inserted into the insulating body 100 (the solution adopted in this embodiment), or they can be injection molded onto the insulating body 100. When the signal connection assembly 200 and the power connection assembly 300 are assembled onto the insulating body 100, the signal connection assembly 200 has a first signal connection terminal 221 exposed on a first side (first side 101) of the insulating body 100 and a second signal connection terminal 222 exposed on a second side (second side 102) of the insulating body 100. Similarly, the power connection assembly 300 has a first power connection terminal 321 exposed on the first side of the insulating body 100 and a second power connection terminal 322 exposed on the second side of the insulating body 100. In this embodiment, the first side and the second side are opposite sides, for example... Figure 1 The left and right sides of the [unclear text]. It should be understood that in different embodiments, depending on the installation environment or the design of the LiDAR connector, the first side and the second side may also be adjacent to each other.
[0045] Please see Figure 5 The insulating body 100 has a signal receiving cavity 110 at a position corresponding to the signal connection assembly 200 for accommodating the signal connection assembly 200, and a power receiving cavity 120 at a position corresponding to the power connection assembly 300 for accommodating the power connection assembly 300. Both the signal receiving cavity 110 and the power receiving cavity 120 penetrate the insulating body 100 in the direction of a first side and a second side.
[0046] A first boss 130 protrudes from the first side surface 101 of the insulating body 100 in a first-side direction (away from the second side). The first boss 130 is used to fit into the mounting hole (not shown) of the housing when the lidar connector is assembled onto the housing of the electronic device. The power receiving cavity 120 and the signal receiving cavity 110 described above are located within the area of the first boss 130, that is, on a projection plane parallel to the first side surface 101, the first boss 130 completely covers the power receiving cavity 120 and the signal receiving cavity 110. The power receiving cavity 120 and the signal receiving cavity 110 penetrate through the first side surface 131 of the first boss 130 in a first-side direction. Those skilled in the art will understand that the first boss 130 is not an essential design feature.
[0047] A second sealing ring 140 is provided on the first side 101 of the insulating body 100 (see...). Figure 1 and Figure 2 The second sealing ring 140 surrounds the outer periphery of the first boss 130, that is, the second sealing ring 140 surrounds the outer periphery of the signal connection assembly 200, the power connection assembly 300, and the shield 400. The second sealing ring 140 can be fitted onto the insulating body 100 through a sealing ring groove 141 provided on the first side surface 101 of the insulating body 100.
[0048] Please continue reading Figure 1 , Figure 2 , Figure 3 and Figure 4 The second side surface 102 of the insulating body 100 extends in a second-side direction (away from the first side) to form a first annular wall 150 and a second annular wall 160. The first annular wall 150 coaxially surrounds the outer periphery of the signal receiving cavity 110, and the second annular wall 160 coaxially surrounds the outer periphery of the power receiving cavity 120. That is, on a projection plane parallel to the second side surface 102, the first annular wall 150 surrounds the signal receiving cavity 110, and the second annular wall 160 surrounds the power receiving cavity 120. The first annular wall 150 and the second side surface 102 of the insulating body 100 together form a first slot 151 with an opening facing the second side. The bottom wall of the first slot 151 communicates with the signal receiving cavity 110 to allow the second signal connection terminal 222 to extend into it in the second-side direction. The second annular wall 160 and the second side surface 102 of the insulating body 100 enclose a second slot 161 with an opening facing the second side. The bottom wall of the second slot 161 communicates with the power receiving cavity 120 so that the second power connection terminal 322 can extend into it in the second side direction. When the signal connection assembly 200 and the power connection assembly 300 are assembled on the insulating body 100, the second signal connection terminal 222 and the second power connection terminal 322 protrude from the second side surface 102 of the insulating body 100 and are respectively located in the first slot 151 and the second slot 161 for electrical connection with the corresponding lidar connector.
[0049] In the first slot 151, a third annular wall 170 is coaxially arranged. The signal receiving cavity 110 described above penetrates the area enclosed by the third annular wall 170 on the second side surface 102 in the second lateral direction, so that the third annular wall 170 and the signal receiving cavity 110 are connected, thereby allowing the second signal connection end 222 to extend into the third annular wall 170 in the second lateral direction. In the second slot 161, a first sealing ring 162 is provided on the inner circumferential surface of the second annular wall 160. The first sealing ring 162 is close to the bottom wall of the second slot 161 (the second side surface 102 of the insulating body 100). To facilitate the stabilization of the first sealing ring 162, a second boss 163 is provided on the bottom wall of the second slot 161. The second boss 163 can be configured as an annular boss distributed around the inner circumference of the second annular wall 160, or it can be configured as a plurality of protrusions spaced apart around the inner circumference of the second annular wall 160. One end of the first sealing ring 162 abuts against the second boss 163, and the other end of the first sealing ring 162 abuts against the insulating inner ring 164. The outer wall of the insulating inner ring 164 is in contact with the inner wall of the second annular wall 160.
[0050] Please see Figure 5 and Figure 6 The insulating body 100 is provided with a plurality of mounting holes 180 at its edge, for example, one mounting hole 180 is provided at each of the four corners of the insulating body 100. Each mounting hole 180 is fitted with a bushing 181, which can be integrally injection molded with the insulating body 100. A ring platform 181a can be provided on the outer periphery of the bushing 181. The axial dimensions of the bushing 181 at both ends of the ring platform 181a can be equal, thus eliminating the need to distinguish the orientation of the bushing 181 and facilitating its installation. At least one plane 181b is provided on the outer peripheral surface of the ring platform 181a, for example, two opposing planes 181b are provided on the outer periphery of the ring platform 181a, to increase the anti-rotation function between the bushing 181 and the mounting holes 180.
[0051] Please see Figure 3 and Figure 7 The signal connection assembly 200, according to its position after being assembled onto the insulating body 100, may include a first exposed portion 200a exposed on a first side of the insulating body 100 and a first insertion portion 200b inserted into the insulating body 100 (signal receiving cavity 110) in a second direction. The first signal connection terminal 221 and the second signal connection terminal 222 are respectively formed at the ends of the first exposed portion 200a and the first insertion portion 200b that are far apart from each other.
[0052] The signal connection assembly 200, depending on the type of components, may include a first insulating body 210 and a signal terminal 220 disposed within the first insulating body 210. The signal terminal 220 may be configured as a high-frequency signal terminal 220. The signal terminal 220 may be inserted into the first insulating body 210, or the signal terminal 220 may be integrally injection molded with the first insulating body 210. One end of the signal terminal 220, as the first signal connection terminal 221, is exposed on one side of the first insulating body 210, and the other end of the signal terminal 220, as the second signal connection terminal 222, is exposed on the other side of the first insulating body 210. The first signal connection terminal 221 may be configured as a fisheye presser foot, and the second signal connection terminal 222 may be configured as a pin structure.
[0053] In this embodiment, the first signal connection terminal 221 and the second signal connection terminal 222 are distributed in mutually perpendicular directions, that is, the signal terminal 220 is L-shaped. Correspondingly, the first insulating body 210 can be configured as an L-shaped structure, having a first insulating section 211 for wrapping the vertical section of the signal terminal 220 and a second insulating section 212 for wrapping the horizontal section of the signal terminal 220. The first insulating section 211 and the vertical section of the signal terminal 220 can serve as the first exposed portion 200a described above, and the second insulating section 212 and the horizontal section of the signal terminal 220 can serve as the first insertion portion 200b described above. The second side of the first insulating section 211 facing the second side direction forms a limiting surface 211a that protrudes vertically from the second insulating section 212 (see...). Figure 7 It is used to limit the engagement with the limiting step 411a of the shield 400 described below, so that after the signal connection assembly 200 is assembled with the shield 400, its first exposed portion 200a is exposed outside the first side 101 of the insulating body 100.
[0054] The first signal connection terminal 221 extends a first insulating section 211 toward a third side direction (e.g., upward direction in the figure), and the second signal connection terminal 222 extends a second insulating section 212 toward a second side direction. When the signal connection assembly 200 is assembled onto the insulating body 100, the first signal connection terminal 221 of the signal terminal 220 faces the third side direction, and the second signal connection terminal 222 extends toward the second side direction from the second side surface 210a of the first insulating body 210, extends from the second side surface 102 of the insulating body 100, and extends into the first slot 151.
[0055] According to its position after assembly onto the insulating body 100, the power connection assembly 300 may include a second exposed portion 300a exposed outside a first side of the insulating body 100 and a second insertion portion 300b inserted into the insulating body 100 (power receiving cavity 120) in a second-side direction. The first power connection terminal 321 and the second power connection terminal 322 are respectively formed at the ends of the second exposed portion 300a and the second insertion portion 300b that are far apart from each other.
[0056] The power connection assembly 300, depending on the type of components, may include a second insulating body 310 and power terminals 320 disposed within the second insulating body 310. The number of power terminals 320 may be determined according to the requirements of different embodiments. The power terminals 320 may be inserted into the second insulating body 310, or the power terminals 320 may be integrally injection molded with the second insulating body 310. One end of the power terminal 320, as a first power connection end 321, is exposed outside one side (third side) of the second insulating body 310, and the other end of the power terminal 320, as a second power connection end 322, is exposed outside the other side (second side) of the second insulating body 310. The first power connection end 321 may be configured as a fisheye presser foot, and the second power connection end 322 may be configured as a pin structure.
[0057] In this embodiment, the first power connection terminal 321 and the second power connection terminal 322 are distributed in mutually perpendicular directions, that is, the power terminal 320 is L-shaped. Correspondingly, the second insulating body 310 can be configured as a matching L-shape, or the second insulating body 310 can be configured as a straight line that thickens along the distribution direction of the first power connection terminal 321 (the solution adopted in this embodiment). The section of the second insulating body 310 near the second power connection terminal 322 (second side direction) can serve as the second insertion portion 300b mentioned above, and the section of the second insulating body 310 near the first power connection terminal 321 can serve as the second exposed portion 300a mentioned above. In this embodiment, the end of the power receiving cavity 120 facing the second side direction can be provided with a cavity bottom wall 121 (see Figure 5The depth of the power receiving cavity 120 is defined such that it is less than the length of the second insulating body 310. This allows the second side 310a (the side near the second power connection end 322) of the second insulating body 310 to abut against the bottom wall 121 of the power receiving cavity 120, while the first side (the section near the first power connection end 321) of the second insulating body 310 is exposed outside the first side 101 of the insulating body 100. In this embodiment, a through hole 122 is formed in the bottom wall 121 corresponding to the position of the second power connection end 322, allowing the power receiving cavity 120 to partially penetrate the second side 102 of the insulating body 100, and allowing the second power connection end 322 to protrude from the second side 102 of the insulating body 100 in a second-side direction. When the power connection assembly 300 is assembled onto the insulating body 100, the first power connection end 321 of the power terminal 320 faces the third side direction, and the second power connection end 322 extends out of the second side surface 310a of the second insulating body 310, extends out of the second side surface 102 of the insulating body 100, and extends into the second slot 161.
[0058] Please see Figure 8 and Figure 9 The shielding component 400 can be die-cast using a die-casting process to form a die-cast part. The shielding component encapsulates the signal connection component 200 and the power connection component 300 into an integrated shielding structure, which has a first isolation cavity 410 that wraps around the outer periphery of the signal connection component 200 along the length direction of the signal connection component 200 and a second isolation cavity 420 that wraps around the outer periphery of the power connection component 300.
[0059] The first isolation cavity 410 has a first opening 410a for exposing the first signal connection terminal 221 and a second opening 410b for exposing the second signal connection terminal 222. The first isolation cavity 410 has a first cavity 411 surrounding the first exposed portion 200a and a second cavity 412 surrounding the first insertion portion 200b, and the first opening 410a and the second opening 410b are respectively formed on the first cavity 411 and the second cavity 412.
[0060] The cross-sectional dimension of the first cavity 411 is larger than that of the second cavity 412, so that it is confined outside by the first side 101 of the insulating body 100. A limiting step 411a is provided at the communication position between the first cavity 411 and the second cavity 412, that is, the bottom wall 121 of the first cavity 411 (the side near the second cavity 412) forms the limiting step 411a surrounding the outer periphery of the second cavity 412. The first cavity 411 penetrates the shield 400 in the direction towards the third side to form the first opening 410a, and the first cavity 411 also penetrates the shield 400 in the direction towards the first side. When the signal connection assembly 200 is assembled in the first isolation cavity 410, the first exposed portion 200a is limited by the limiting step 411a and exposed outside the first side of the insulating body 100 in the first cavity 411. The first signal connection end 221 extends out of the first opening 410a in the direction of the third side, so that the first signal connection end 221 extends out of the first cavity 411 through the first opening 410a and is exposed on the third side 401 of the shield 400.
[0061] The length of the second cavity 412 is greater than the length of the first plug-in portion 200b. When the first plug-in portion 200b is inserted into the second cavity 412, the second signal connection terminal 222 is located inside the second cavity 412 at the end away from the first cavity 411 (the end facing the second side). After the shield 400 is assembled onto the insulating body 100, the second cavity 412, carrying the signal connection assembly 200 assembled therein, is inserted into the signal receiving cavity 110. The end of the second cavity 412 away from the first cavity 411 extends out of the second side 102 of the insulating body 100 and passes through the third annular wall 170 described above, finally located in the first slot 151. The second opening 410b described above is coaxially formed on the end of the second cavity 412 extending out of the second side of the insulating body 100. The second signal connection terminal 222 is accommodated in the second cavity 412 and communicates with the outside through the second opening 410b.
[0062] The second isolation cavity 420 partially encloses the outer periphery of the second exposed portion 300a. The second isolation cavity 420 is provided with a third opening 420a through which the first power connection terminal 321 protrudes outward, and a fourth opening 420b through which the second power connection terminal 322 protrudes. In this embodiment, the second isolation cavity 420 penetrates the shielding member 400 in a third-side direction to form the third opening 420a, and penetrates the shielding member 400 in a second-side direction to form the fourth opening 420b. The first power connection terminal 321 protrudes through the third opening 420a in a third-side direction and is exposed on the third side surface 401 of the shielding member 400. The second insertion portion 300b protrudes through the fourth opening 420b in a second-side direction and is exposed on the second side surface 402 of the shielding member 400. One end of the second plug-in portion 300b protruding from the second isolation cavity 420 is inserted into the insulating body 100, and its second power connection end 322 is exposed on the second side 102 of the insulating body 100 and located in the second slot 161.
[0063] Please see Figure 10 In this embodiment, the grounding assembly 500 includes a base 510 and a first grounding connection terminal 520 and a second grounding connection terminal 530 disposed on the base 510. The first grounding connection terminal 520, the first signal connection terminal 221, and the first power connection terminal 321 face the same direction. The second grounding connection terminal 530 is configured as an elastic arm for elastically abutting against the electronic device housing. The base 510 is generally U-shaped with an opening facing a second side. It has a first side arm 511 and a second side arm 512 distributed along the parallel direction of the power connection assembly 300 and the signal connection assembly 200, and a substrate 513 connecting the first sides of the first side arm 511 and the second side arm 512. At least one first grounding connection terminal 520 is disposed on each of the first side arm 511 and the second side arm 512. The first grounding connection terminals 520 extend towards a third side and can be configured as fisheye feet. The second grounding connection end 530 is formed by bending from the third side edge of the substrate 513 toward the first side and then extending toward the fourth side away from the third side. The distance between the second grounding connection end 530 and the substrate 513 gradually increases toward the fourth side. The end of the second grounding connection end 530 is also bent toward the second side to form a hook portion 531 that moves toward the fourth side and toward the substrate 513.
[0064] The grounding component 500 can be mounted on the shield 400 in the area exposed outside the first side of the insulating body 100. For example, the grounding component 500 and the first exposed portion 200a of the signal connection component 200 can be mounted in the same area of the shield 400. In this embodiment, a plurality of plugs 540 can be provided on the second side of the grounding component 500 facing the second side direction. For example, two plugs 540 are provided on the second side edges of the first side arm 511 and the second side arm 512. Correspondingly, a slot 430 is provided on the shield 400 at the position corresponding to each plug 540 for the plug 540 to be inserted therein. When the grounding component 500 is inserted into the shield 400, the U-shaped base 510 wraps around the outer periphery of the first exposed portion 200a, the first grounding connection end 520 faces the third side direction, and the second grounding connection end 530 is located outside the first side of the substrate 513.
[0065] Based on the above embodiments, the assembly method of the laser radar connector of this utility model is as follows: First, the bushing 181 and the insulating body 100 are integrally injection molded, the signal terminal 220 and the first insulating body 210 are integrally injection molded to form the signal connection assembly 200, and the power terminal 320 and the second insulating body 310 are integrally injection molded to form the power connection assembly 300; then, the power connection assembly 300 is pressed into the power receiving cavity 120 of the plastic body, so that the first power connection end 321 of the power connection assembly 300 is exposed outside the first side of the insulating body 100, and the second power connection end 322 is exposed outside the second side of the insulating body 100 and located in the second slot 161; next, the signal connection assembly 200 is pressed into the first isolation cavity 410 of the shield 400, and the shield 400 carrying the signal connection assembly 200 is pressed into the signal receiving cavity 120 of the insulating body 100. In the receiving cavity 110, the first cavity 411 of the shield 400 and its first exposed portion 200a are both exposed outside the first side of the insulating body 100. The end of the second cavity 412 of the shield 400 away from the first cavity 411 and its second signal connection terminal 222 are both located outside the second side of the insulating body 100 and in the first slot 151. Then, the grounding component 500 is pressed into the area of the shield 400 exposed outside the first side of the insulating body 100, and the grounding component 500 is fixed to the shield 400 by riveting. Then, the first sealing ring 162 is pressed into the bottom of the second slot 161, and the insulating inner ring 164 is pressed against the first sealing ring 162 to fix the first sealing ring 162. Finally, the second sealing ring 140 is pressed into the first side 101 of the insulating body 100 to complete the assembly of the entire lidar connector.
[0066] In summary, the lidar connector of this utility model has the following beneficial effects: It integrates the power connection component 300 and the signal connection component 200 onto a single insulating body 100, achieving integration of the lidar connector and supporting multi-channel parallel transmission of power and signals; the shielding component 400 is designed to shield and isolate the signal connection component 200 and the power connection component 300, fully covering the coaxial high-frequency signal terminal 220, while the shielding component 400 extends to the power connection component 300 to provide enveloping protection, achieving stable transmission of high-frequency signals and power signals; the grounding component 500 is designed to have a first grounding connection terminal 520 and a second grounding connection terminal 530, the first grounding connection terminal 520 being connected to the first power connection terminal 321 and the first signal connection terminal 220... The first connection end 221 faces the same direction to allow simultaneous connection to the target object (e.g., circuit board). The second grounding connection end 530 is designed as a flexible arm structure, which elastically abuts against the electronic device housing, thereby achieving a dual grounding mode, effectively shielding external signals, eliminating electric fields and suppressing electric field coupling interference, and ensuring the integrity of signal transmission. A first sealing ring 162 is designed in the second slot 161 to achieve a waterproof seal between the lidar connector and the mating lidar connector. A second sealing ring 140 is designed on the first side 101 of the insulating body 100. This second sealing ring 140 surrounds the first exposed portion 200a of the power connection component 300, the second exposed portion 300a of the signal connection component 200, and the shielding member 400, thereby achieving a waterproof seal between the lidar connector and external devices. In summary, the lidar connector of this invention can achieve power and signal integration, meeting the requirements of high integration, high reliability, and high-speed signal transmission in some applications such as autonomous driving and advanced driver assistance systems (ADAS).
