Description

Technical Field

[0001] The utility model relates to an electric connector docking structure and a laser radar, in particular to an electric connector docking structure of a non-floating electric connector and a laser radar equipped with the electric connector docking structure. Background Art

[0002] In the field of electronics, it is sometimes necessary to electrically connect circuit boards arranged on different structural parts. In this case, it is necessary to pre-install electrical connectors on the circuit boards to be connected, and to achieve electrical connection of the circuit boards by docking the electrical connectors. In addition, due to assembly requirements, it is sometimes necessary to fix the position of the structural part itself equipped with the circuit board or the circuit board itself before completing the assembly. In other words, after docking the electrical connectors arranged on the circuit boards, the position of the corresponding structural part will be constrained by the docking electrical connectors. Therefore, it is necessary to achieve position alignment between the electrical connectors while achieving alignment between the structural parts or between the circuit board and the structural part.

[0003] When using electrical connectors to connect circuit boards, due to the production tolerance and assembly tolerance of components, for example, the position of the electrical connectors on each circuit board may deviate, making it difficult to adjust the position of the structural parts corresponding to the circuit board. Therefore, in order to achieve high-precision docking of the electrical connectors, after the electrical connectors are docked, the position of the structural parts connected to the electrical connectors needs to have a certain adjustment space.

[0004] A floating electrical connector can be used to obtain this adjustment space, thereby realizing the floating function of the electrical connector. In the prior art, a floating electrical connector structure is provided, including an insulating shell, a base, and a plurality of terminals. The insulating shell is provided with a limit hole between its two sides, and the base is provided with a support column that can extend into the limit hole at a position corresponding to the limit hole. The support column and the two opposite walls forming the limit hole are separated by a first and a second gap. The floating function of the floating electrical connector can be realized by utilizing the first and the second gaps between the support column and the two opposite walls of the limit hole. By adjusting the floating function of the floating electrical connector, the position deviation caused by the tolerance can be reduced or eliminated, so that the positions of the two electrical connectors can be aligned to complete the docking. Utility Model Content

[0005] Since floating electrical connectors are relatively high in cost and relatively large in size, using floating electrical connectors to fine-tune the position of the electrical connectors will increase costs and device size.

[0006] For example, in the structure of a device such as a laser radar, there may also be the above-mentioned circuit board structure that needs to be electrically connected to each other. Therefore, it is also necessary to eliminate the position deviation caused by various tolerances.

[0049] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0050] Figure 1 A side cross-sectional view of an example of a laser radar according to some embodiments is shown. Figure 2A partial structural schematic diagram of a laser radar example in some implementation modes is shown. Figure 3 FIG4( a ) shows a perspective view of a structure example of a base plate involved in some embodiments, and FIG4( b ) shows a perspective view of a structure example of a flexible circuit board involved in some embodiments.

[0051] In some embodiments, Figures 1 to 3 As shown, the laser radar 100 includes a base plate 1, a lens barrel 2, and a second circuit board 3. One side of the base plate 1 (for example, Figure 1 Optical components such as the lens barrel 2 may be disposed on the upper side thereof.

[0052] like Figure 2 , 3 As shown, the lens barrel 2 is connected to the base plate 1. In some embodiments, the connection method can be snap connection, screw connection, welding, etc. In the lens barrel 2, for example, optical components such as lenses not shown are configured. A second circuit board 3 is fixed on the lens barrel 2. In some embodiments, it can be fixed by screws, adhesives, etc. In some embodiments, the second circuit board 3 can be a transmitting circuit board (for example, TX board) carrying a laser / laser chip, a receiving circuit board (for example, RX board) carrying a receiver / receiver chip, or a transceiver circuit board (for example, TRX board) carrying a transceiver device / transceiver chip at the same time. Among them, the transmitting circuit board (for example, TX board) is used to generate laser and transmit through the lens barrel 2, the receiving circuit board (for example, RX board) is used to receive echo light through the lens barrel 2 and generate electrical signals for subsequent processing, and the transceiver circuit board (for example, TRX board) is used to perform transceiver processing of laser and echo light through the lens barrel 2. In some embodiments, as shown in FIG. 4 (a), the other side of the base plate 1 can include a first mounting surface A, and the first mounting surface A is used to mount the first circuit board 9 described later. In other embodiments, the first mounting surface A may also be located on the same side of the bottom plate 1 together with the lens barrel 2 and other components. For example, the first circuit board 9 and the lens barrel 2 may be disposed on the same side of the bottom plate 1 together.

[0053] In some embodiments, the bottom plate 1 and the lens barrel 2 are connected to each other to form an integral body, so the two can be regarded as a whole as a first structural member, and in other embodiments, the bottom plate 1 can also be regarded as the first structural member. In addition, in other embodiments, the bottom plate does not necessarily carry a lens barrel, but can also carry any other structure suitable for being carried by the bottom plate.

[0054] like Figures 1 to 3As shown, the electrical connector docking structure further includes a flexible circuit board 4. The flexible circuit board 4 is fixedly connected to the first structural member. In some embodiments, the first end 42 of the flexible circuit board 4 is electrically connected to the second circuit board 3, and is connected to the lens barrel 2 via the second circuit board 3. In other embodiments, a circuit can be formed on the first structural member, and the first end 42 of the flexible circuit board 4 is connected to the circuit on the first structural member, so that the second circuit board 3 does not need to be additionally provided.

[0055] In some embodiments, the second end 41 of the flexible circuit board 4 may include a hard circuit board 43. By adopting such a structure in which the flexible circuit board 4 is connected to the hard circuit board 43, it is possible to facilitate the positioning of the first electrical connector 5 described later. However, the present disclosure is not limited thereto. In some embodiments, the second end 41 of the flexible circuit board 4 may not include a hard circuit board. In some embodiments in which the second end 41 of the flexible circuit board 4 does not include a hard circuit board, the first electrical connector 5 described later, the through portion 6, etc. may be disposed on the flexible circuit board 4.

[0056] Since the flexible circuit board 4 is bendable and has a certain flexibility, the second end 41 of the flexible circuit board 4 is movable. In some embodiments, the hard circuit board 43 connected to the second end 41 of the flexible circuit board 4 is movable. Figures 1 to 3 As shown, a first electrical connector 5 is disposed on the rigid circuit board 43, and the first electrical connector 5 is electrically connected to the flexible circuit board 4 through the rigid circuit board 43. The first electrical connector 5 can be welded on the rigid circuit board 43 connected to the flexible circuit board 4, so as to realize the electrical connection between the first electrical connector 5 and the flexible circuit board 4. In some embodiments where the second end 41 of the flexible circuit board 4 does not include a rigid circuit board, the first electrical connector 5 can be directly disposed on the flexible circuit board 4.

[0057] In some embodiments, as shown in FIG. 4(a) and FIG. 4(b), a through portion 6 may be formed on the rigid circuit board 43, and a limiting protrusion 13 may be protrudingly provided on the first mounting surface A of the bottom plate 1. In some embodiments, the through portion 6 includes a through hole that penetrates the rigid circuit board 43, and the through hole may be located in the middle of the rigid circuit board 43, and the limiting protrusion includes a limiting column that passes through the through hole. The size of the cross section of the limiting protrusion 13 parallel to the first mounting surface A (for example, the outer diameter of the limiting protrusion 13) is smaller than the radial size of the through portion 6 (for example, the inner diameter of the through portion 6), and the limiting protrusion 13 passes through the through portion 6. The gap between the limiting protrusion 13 and the through portion 6 is used to limit the range of movement of the rigid circuit board 43 in a direction parallel to the first mounting surface A to a certain extent, so that the position of the first electrical connector 5 relative to the first mounting surface A can be fine-tuned in a direction parallel to the first mounting surface A. In some embodiments where the second end 41 of the flexible circuit board 4 does not include a rigid circuit board, the through portion 6 may be directly provided on the flexible circuit board 4.

[0058] As shown in FIG. 4(a) and FIG. 4(b), the through-portion 6 is a circular through-hole of the TRX plate, and the limiting protrusion 13 is a cylindrical limiting protrusion. However, the shape of the through-portion 6 is not limited to a circular hole. In other embodiments, it can also be a square hole or other shapes. The shape of the limiting protrusion 13 is not limited to a cylindrical shape, but can also be a prismatic shape or other shapes. As long as the size of the cross section of the limiting protrusion 13 parallel to the first mounting surface A is smaller than the radial size of the through-portion 6, the size relationship between the two can be designed according to the adjustment range required for the second end of the flexible circuit board in the direction parallel to the first mounting surface.

[0059] like Figure 1 As shown in FIG. 4( a ), in some embodiments, a positioning hole 7 is provided inside the limiting protrusion 13 , and the positioning hole 7 extends from the top of the limiting protrusion 13 to the inside of the limiting protrusion 13 in a direction perpendicular to the first mounting surface A. Figure 1 As shown, in some embodiments, the positioning hole 7 passes through the limiting protrusion 13 and the bottom plate 1 to form a through hole. In other embodiments, the positioning hole 7 may not pass through the bottom plate 1 or the limiting protrusion 13, but may be formed as a blind hole.

[0060] like Figure 1 As shown, the electrical connector docking structure further includes a limiting nail 8, the outer diameter of the nail head of the limiting nail 8 is greater than the radial dimension of the through portion 6, and the limiting nail 8 passes through the through portion 6 and is inserted into the positioning hole 7. The nail head of the limiting nail 8 is used to limit the movement range of the second end 41 of the flexible circuit board 4 in the direction perpendicular to the first mounting surface A, so as to reduce or prevent the second end 41 of the flexible circuit board 4 from jumping out in the direction perpendicular to the first mounting surface A when the first electrical connector 5 is subsequently docked with the second electrical connector 10.

[0061] like Figure 1 As shown, in some embodiments, the height of the limiting protrusion 13 can be greater than the thickness of the second end 41 of the flexible circuit board 4. After the limiting nail 8 is inserted, it can reduce or prevent the nail head of the limiting nail 8 from pressing the second end 41 of the flexible circuit board 4, resulting in the second end 41 of the flexible circuit board 4 being unable to be fine-tuned relative to the first mounting surface A in a direction parallel to the first mounting surface A, and it can also reduce or avoid the limiting nail 8 squeezing the circuit board to cause damage to the components on the circuit board.

[0062] In some embodiments, the stopper includes one or more of a through portion 6, a positioning hole 7, a stopper pin 8, or a stopper protrusion 13, and the stopper is at least partially disposed on the first mounting surface A. Figure 1 As shown, in some embodiments, the through portion 6 and the limiting protrusion 13 in the limiter are arranged on the first mounting surface A. The movement range of the second end 41 of the flexible circuit board 4 along the direction perpendicular to the first mounting surface A is limited by the limiting pin 8, the positioning hole 7 extending through the limiting protrusion 13 to the inside of the bottom plate 1, and the through portion 6. In other embodiments, the limiting protrusion 13 may not be provided, and the positioning hole 7 may be opened on the first mounting surface A, and the limiting pin 8 may be inserted into the positioning hole 7 through the through portion 6. In this case, the limiting pin 8 can be used to limit the movement range of the second end 41 of the flexible circuit board 4 along the direction perpendicular to the first mounting surface A.

[0063] In some embodiments, Figure 1 As shown, the electrical connector docking structure may include a first circuit board 9. Figure 3 As shown, the first circuit board 9 has a second mounting surface B opposite to the first mounting surface A of the base plate 1. On the second mounting surface B, a second electrical connector 10 electrically connected to the first circuit board 9 is arranged. Figure 1 As shown, the second electrical connector 10 is configured to dock with the first electrical connector 5. By docking the first electrical connector 5 with the second electrical connector 10, electrical connection and signal transmission between the second circuit board 3 and the first circuit board 9 are achieved.

[0064] like Figure 1 , Figure 3 As shown in FIG. 4( b ), in some embodiments, the through portion 6 is arranged to be farther away from the first end 42 of the flexible circuit board than the first electrical connector 5 . Thus, more space can be freed for circuit wiring between the first electrical connector 5 and the first end 42 .

[0065] like Figure 1 to Figure 3As shown, in the laser radar 100, the first circuit board 9 is connected to the base plate 1 (for example, the first structural member). On the base plate 1, a plurality of positioning protrusions 11 are provided, and the interior of the positioning protrusions 11 is provided with positioning holes in a direction perpendicular to the first mounting surface A. On the first circuit board 9, a protrusion 12 is provided corresponding to the positioning protrusion 11. The protrusion 12 cooperates with the positioning hole in the positioning protrusion 11, so that the relative position relationship between the first circuit board 9 and the base plate 1 can be determined. In addition, in other embodiments, the positioning hole can be provided on the first circuit board 9, and the protrusion can be provided on the base plate 1, and other existing positioning methods such as screw positioning and pin positioning can also be used to achieve the positioning between the first circuit board 9 and the base plate 1. In addition, in other embodiments, the height of the positioning protrusion 11 can be further limited to avoid interference between the base plate 1 and the devices mounted on the first circuit board 9.

[0066] Next, Figure 1 to Figure 4(b) The docking process of the electrical connector docking structure involved is described.

[0067] like Figure 1 to Figure 4(b) As shown, first, the first end 42 of the flexible circuit board 4 is connected to the first structural member. In some embodiments, the first structural member may include a lens barrel 2 and a base plate 1, and the first end 42 of the flexible circuit board 4 may be electrically connected to a second circuit board 3, which is connected to the lens barrel 2.

[0068] Next, the second end 41 of the flexible circuit board 4 is bent to the first mounting surface A of the base plate 1 . The second end 41 of the flexible circuit board 4 is movable and is provided with a first electrical connector 5 electrically connected to the flexible circuit board 41 .

[0069] Then, the second end 41 of the flexible circuit board 4 is limited in the direction perpendicular to the first mounting surface A by using a stopper at least partially configured on the first mounting surface A. In some embodiments, the stopper may include a through portion 6, which penetrates the second end 41 of the flexible circuit board 4. The stopper may include a positioning hole 7, which is configured on the first mounting surface A. In addition, the stopper may include a stopper nail 8, the outer diameter of the nail head of the stopper nail 8 is greater than the radial dimension of the through portion 6. By inserting the stopper nail 8 through the through portion 6 and into the positioning hole 7, the movement range of the second end 41 of the flexible circuit board 4 in the direction perpendicular to the first mounting surface A can be limited. In other embodiments, the stopper may also include a stopper protrusion 13, which is protrudingly arranged on the first mounting surface A, and the positioning hole 7 penetrates from the top of the stopper protrusion 13 in the direction perpendicular to the first mounting surface A at least to the inside of the stopper protrusion 13, and the size of the cross section of the stopper protrusion 13 parallel to the first mounting surface A is smaller than the radial size of the through portion 6. By allowing the limiting protrusion 13 to pass through the through-portion 6, the relative position of the second end 41 of the flexible circuit board 4 with respect to the base plate 1 along the direction parallel to the first mounting surface A can be adjusted within the range of the gap between the limiting protrusion 13 and the through-portion 6, thereby appropriately limiting the movement range of the second end 41 of the flexible circuit board 4 along the direction parallel to the first mounting surface A.

[0070] The first electrical connector 5 is docked with the second electrical connector 10, and the second mounting surface B of the first circuit board 9 is aligned with the first mounting surface A by moving the second end 41 of the flexible circuit board 4 relative to the first mounting surface A in a direction parallel to the first mounting surface A. The second electrical connector 10 is arranged on the second mounting surface B and is electrically connected to the first circuit board 9, and the second mounting surface B is opposite to the first mounting surface A. In some embodiments, regarding the docking of the first electrical connector 5 and the second electrical connector 10, an operator or a robot can align and dock the first electrical connector 5 on the base plate 1 with the second electrical connector 10 on the first circuit board 9 through manual or machine vision. Regarding the alignment of the second mounting surface B with the first mounting surface A, the flexibility of the flexible circuit board 4 can be utilized, and the second mounting surface B of the first circuit board 9 can be aligned with the first mounting surface A of the base plate 1 by moving the second end 41 of the flexible circuit board 4 relative to the first mounting surface A in a direction parallel to the first mounting surface A, for example, aligning the positioning hole in the positioning protrusion 11 with the protrusion 12 on the first circuit board 9.

[0071] As described above, according to the electrical connector docking structure and laser radar 100 involved in some embodiments of the present disclosure, the first electrical connector 5 is movable in a direction parallel to the first mounting surface A by utilizing the bendable and soft characteristics of the flexible circuit board 4. Therefore, the first electrical connector 5 and the second electrical connector 10 are set as relatively low-cost fixed electrical connectors, and the relative position between the two can also be adjusted. As a result, the electrical connector docking can be achieved with high precision, and the overall cost of the electrical connector docking structure and the laser radar having the electrical connector docking structure can be reduced.

[0072] According to the electrical connector docking structure and laser radar 100 involved in some embodiments of the present disclosure, a limiter is used to limit the movement range of the second end 41 of the flexible circuit board in a direction perpendicular to the first mounting surface A. Therefore, the second end 41 of the flexible circuit board 4 can be prevented from moving out in a direction perpendicular to the first mounting surface A due to the elasticity of the flexible circuit board 4, thereby improving the stability of the electrical connector docking.

[0073] In addition, according to the electrical connector docking structure and laser radar 100 involved in some embodiments of the present disclosure, the size of the cross section of the limiting protrusion 13 parallel to the first mounting surface A is smaller than the radial size of the through portion 6, so that the limiting protrusion 13 passes through the through portion 6 and the limiting protrusion 13. Therefore, the gap between the limiting protrusion 13 and the through portion 6 can be used to limit the movement range of the second end 41 of the flexible circuit board 4 (for example, the first electrical connector 5) in the direction parallel to the first mounting surface A. In this way, the difficulty of aligning the electrical connector due to excessive movement of the first electrical connector 5 in the direction parallel to the first mounting surface A can be prevented.

[0074] The electrical connector docking structure involved in other embodiments is described below.

[0075] Figure 5(a) shows a stereoscopic view of a structural example of the base plate 1 and the flexible circuit board 4 in some embodiments, Figure 5(b) shows a structural schematic diagram of the flexible circuit board 4 in Figure 5(a), and Figure 5(c) shows a schematic diagram of a structural example of the first mounting surface A of the base plate 1.

[0076] As shown in FIG. 5(b), the through-portion includes a plurality of (for example, two) through holes (for example, through-portion 6') that penetrate the rigid circuit board 43, and the plurality of through-portions 6' are formed on the side of the rigid circuit board 43, and the edges of the plurality of through-portions 6' are in contact with the side of the rigid circuit board 43. In other embodiments, the rigid circuit board 43 may not be provided, and the through-portion 6' may be directly provided at the second end 41 of the flexible circuit board 4. As shown in FIG. 5(c), the limiting protrusion may include a plurality of (for example, two are shown in the figure) limiting columns (for example, limiting protrusion 13') that pass through the through-portion 6'. Positioning holes 7' are respectively formed inside the plurality of limiting protrusions 13'. As shown in FIG. 5(a), a plurality of limiting nails 8' respectively pass through the plurality of through-portions 6' and are inserted into the plurality of positioning holes 7'.

[0077] according to Figure 5(a) to Figure 5(c) The electrical connector docking structure shown can achieve the docking of the electrical connector with high precision, and can reduce the overall cost and volume of the electrical connector docking structure and the laser radar having the electrical connector docking structure.

[0078] The following describes the electrical connector docking structure and the electrical connector docking process involved in some further embodiments.

[0079] FIG. 6( a ) is a perspective view showing a structural example of a base plate 1 and a flexible circuit board 4 according to some embodiments, and FIG. 6( b ) is a perspective view showing the structure of the base plate 1 in FIG. 6( a ). Figure 6(a) to Figure 6(b) The electrical connector docking structure shown is Figure 1 to Figure 5(c) The main difference between the electrical connector docking structures shown in the figure is the structure of the stopper. Figure 6(a) to Figure 6(b) The electrical connector docking structure shown is described.

[0080] As shown in FIG. 6(a) and FIG. 6(b), the limiter also includes at least one (for example, two) limit hooks 14. On the first mounting surface A of the base plate 1, two limit hooks 14 are protrudingly provided, and the two limit hooks 14 respectively include a root extending from the first mounting surface A in a direction perpendicular to the first mounting surface A toward a side away from the first mounting surface A, and include a hook portion extending from the root in a direction parallel to the first mounting surface A. In some embodiments, the two limit hooks 14 are arranged opposite to each other, and the hook portions of the two limit hooks 14 can extend toward each other to form a pair of opposite L-shaped hooks. In addition, as shown in FIG. 6(a), the second end 41 of the flexible circuit board 4 is configured to extend at least partially (the two side edge portions of the hard circuit board 43 in the figure) to between the hook portions of the two limit hooks 14 and the first mounting surface A respectively.

[0081] According to the above structure, the two limit hooks 14 can limit the movement range of the second end 41 of the flexible circuit board 4 along the direction perpendicular to the first mounting surface A, thereby reducing or preventing the second end 41 of the flexible circuit board 4 from jumping out along the direction perpendicular to the first mounting surface A, and improving the stability of the electrical connector docking.

[0082] Figure 6(a) to Figure 6(b) The structure with a pair of limit hooks 14 is shown, but the present disclosure is not limited thereto. In other embodiments, a limit hook may be disposed on one side of the second end 41 of the flexible circuit board 4, or a plurality of limit hooks may be disposed on both sides of the second end 41 of the flexible circuit board 4, as long as the limit hooks can be used to limit the movement range of the second end 41 of the flexible circuit board 4 perpendicular to the first mounting surface A.

[0083] As shown in FIG. 6(a) and FIG. 6(b), in some embodiments, the stopper may further include a stopper groove 15. For example, a stopper groove 15 may be provided on the first mounting surface A, and the width of the stopper groove 15 may be greater than the width of the second end 41 of the flexible circuit board 4, so that the second end 41 of the flexible circuit board 4 may be embedded in the stopper groove 15, and the stopper groove 15 may be used to limit the movement range of the second end 41 of the flexible circuit board 4 parallel to the first mounting surface A. Thus, the difficulty of aligning the electrical connector due to excessive movement of the first electrical connector 5 in a direction parallel to the first mounting surface A may be prevented.

[0084] As shown in FIG. 6(a) and FIG. 6(b), in some embodiments, the limiter may further include a limit stopper 16. For example, a limit stopper 16 may be provided on the first mounting surface A (e.g., in the limit groove 15), so that the top end of the second end 41 of the flexible circuit board 4 is arranged toward the limit stopper 16, so that the limit stopper 16 can be used to further limit the movement range of the second end 41 of the flexible circuit board 4 parallel to the first mounting surface A. In this way, the difficulty of aligning the electrical connector due to excessive movement of the first electrical connector 5 in a direction parallel to the first mounting surface A can be prevented.

[0085] In some embodiments, the limiter includes one or more of the limit hook 14, the limit slot 15 and the limit block 16. In other embodiments, any one or any combination of the limit hook 14, the limit slot 15 or the limit block 16 can also be configured as the limiter.

[0086] Below Figure 6(a) to Figure 6(b) Here, the docking process of the electrical connector docking structure involved is described. Figure 1 to Figure 4(b) The steps of the docking process of the electrical connector docking structure involved are the same and the description thereof is omitted.

[0087] like Figure 6(a) to Figure 6(b)As shown, in some embodiments, the limiter includes at least one limit hook 14, which is protrudingly disposed on the first mounting surface A, and the limit hook includes a root extending from the first mounting surface A in a direction perpendicular to the first mounting surface A, and a hook portion extending from the root in a direction parallel to the first mounting surface A. After the second end 41 of the flexible circuit board 4 is bent to the first mounting surface A, the second end 41 of the flexible circuit board 4 is configured to at least partially extend between the hook portion of the limit hook 14 and the first mounting surface A, so that the hook portion of the limit hook 14 can be used to limit the movement range of the second end 41 of the flexible circuit board 4 in a direction perpendicular to the first mounting surface A.

[0088] like Figure 6(a) to Figure 6(b) As shown, in other embodiments, the limiter further includes a limit groove 15, which is provided on the first mounting surface A, and the width of the limit groove 15 is greater than the width of the second end 41 of the flexible circuit board 4. By embedding the second end 41 of the flexible circuit board 4 into the limit groove 15, the limit groove 15 can be used to limit the movement range of the second end 41 of the flexible circuit board 4 in a direction parallel to the first mounting surface A.

[0089] like Figure 6(a) to Figure 6(b) As shown, in some other embodiments, the limiter further includes a limit stopper 16, and the limit stopper 16 is disposed on the first mounting surface A. By configuring the top end of the second end 41 of the flexible circuit board 4 toward the limit stopper 16, the limit stopper 16 can be used to further limit the movement range of the second end 41 of the flexible circuit board 4 in a direction parallel to the first mounting surface A.

[0090] As mentioned above, according to Figure 6(a) to Figure 6(b) The structure of the limiter shown can also achieve the docking of the electrical connector with high precision, and can reduce the overall cost and volume of the electrical connector docking structure and the laser radar having the electrical connector docking structure.

[0091] The structure of a laser radar according to another embodiment is described below.

[0092] FIG. 7( a ) is an exploded perspective view of an example of a laser radar 100 ′ according to some embodiments, and FIG. 7( b ) is an exploded perspective view of the laser radar 100 ′ of FIG. 7( a ) observed from another angle.

[0093] exist Figure 1 In the laser radar 100 shown, the first circuit board 9 is connected to the first structural member. For example, the first circuit board 9 is connected to the bottom plate 1 through the positioning protrusion 11 and the protrusion 12.

[0094] However, in Figure 7(a) to Figure 7(b)In the laser radar 100' shown, the first circuit board 9 is not directly connected to the first structure, but is arranged on the second structure 17, and the second structure 17 is connected to the first structure. Figure 7(a) to Figure 7(b) As shown, in some embodiments, the first circuit board 9 is clamped on the positioning protrusion 11' provided on the second structural member 17 through a clamping slot. In addition, a positioning hole is provided inside the positioning protrusion 11'. On the first circuit board 9, a protrusion 12' is provided corresponding to the positioning protrusion 11'. The protrusion 12' cooperates with the positioning hole in the positioning protrusion 11', so that the relative position relationship between the first circuit board 9 and the base plate 1 can be determined. In addition, in other embodiments, the height of the positioning protrusion 11' can also be further limited to avoid interference between the base plate 1 and the components mounted on the first circuit board 9.

[0095] The above is a description of the electrical connector docking structure and laser radar involved in the present disclosure. It should be considered that all aspects of the embodiments disclosed this time are only examples and are not restrictive. The scope of the present disclosure is indicated by the claims, not by the above embodiments. The scope of the present disclosure also includes all modifications and variations within the meaning and scope equivalent to the claims.
