[0002] Currently, the connector of a USB Type-C plug is soldered parallel to the circuit board. The overall length of the connector after connection is the sum of the lengths of the connector and the circuit board. Furthermore, the circuit board size differs between USB 2.0 and 3.0 due to the different number of terminals. For USB 2.0, the circuit board length is 9mm, and the sum of the connector and circuit board length is generally 14mm. For USB 3.0, the circuit board length is 30mm, and the sum of the connector and circuit board length is generally 35mm. This places space requirements on electronic devices; there must be at least 14mm or 35mm of space outside the interface for the connector and circuit board to be properly inserted and used. Utility Model Content

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0035] In related technologies, the connector of a USB Type-C plug is soldered parallel to the circuit board. After the two are connected, the overall length is the sum of the lengths of the connector and the circuit board, which is relatively long. This means that there must be a certain amount of space outside the interface of the electronic device so that the connector and the circuit board can be inserted and used normally, which puts high demands on the space of the electronic device.

[0036] In view of this, the present invention provides an electronic device and a vehicle dashcam, wherein the electronic device has the Type-C connector vertically arranged on the circuit board to reduce the space requirements of the electronic device.

[0037] like Figures 1 to 6 As shown, the electronic device 100 provided in this embodiment of the present invention includes a circuit board 10 and a Type-C connector 20. The circuit board 10 has a first side 11 and a second side 12 disposed opposite to each other, and a through hole 13 is provided through the circuit board 10 from the first side 11 to the second side 12. The Type-C connector 20 includes a housing 21, a first terminal assembly 22, and a second terminal assembly 23. The housing 21 has a first end 211 and a second end 212 disposed opposite to each other. The first terminal assembly 22 and the second terminal assembly 23 are both installed inside the housing 21 and extend out of the housing 21 from the first end 211 and bend and extend in opposite directions. The housing 21 is disposed in the through hole 13, and the first terminal assembly 22 and the second terminal assembly 23 are both electrically connected to the circuit board 10. The first side 11 and the second side 12 of the circuit board 10 are disposed along their thickness direction, and the first end 211 and the second end 212 of the housing 21 are disposed along the length direction of the Type-C connector 20.

[0038] Using the above technical solution, a through-hole 13 is disposed through the circuit board 10, and a housing 21 is disposed within the through-hole 13, so that the Type-C connector 20 can pass through the through-hole 13, thereby enabling the Type-C connector 20 to pass through the circuit board 10. The through-hole 13 is disposed through the thickness direction of the circuit board 10, so the Type-C connector 20 is perpendicular to the circuit board 10. This arrangement can greatly reduce the sum of the overall lengths of the Type-C connector 20 and the circuit board 10 in the length direction of the Type-C connector 20, that is, the length of the through-hole 13 in the axial direction, the length of the Type-C connector 20 on the first side 11 of the circuit board 10, and the length of the Type-C connector 20 on the second side 12 of the circuit board 10. For example, for a circuit board 10 corresponding to the USB 3.0 specification, the space required by the existing parallel arrangement is 30mm. With the arrangement method of this application, the required space can be reduced to the length of the Type-C connector 20 itself and the size of the soldering position. In addition, the perforation 13 limits the Type-C connector 20 in the length and width directions of the circuit board 10, which can prevent the Type-C connector 20 from shaking.

[0039] By configuring the first terminal assembly 22 and the second terminal assembly 23 to both extend from the first end 211 of the housing 21 and bend in opposite directions, the first terminal assembly 22 and the second terminal assembly 23 can be electrically connected to the circuit board 10 when the Type-C connector 20 is inserted through the through hole 13, particularly through soldering. Therefore, the electronic device 100 of this application, while achieving electrical connection between the Type-C connector 20 and the circuit board 10, can significantly reduce the overall length of the Type-C connector 20 and the circuit board 10 in the longitudinal direction, thus reducing the space requirements of the electronic device 100.

[0040] In one embodiment, both the first terminal assembly 22 and the second terminal assembly 23 are electrically connected to the first side 11 of the circuit board 10, and the second end 212 of the housing 21 is disposed near the second side 12 of the circuit board 10. That is, when the Type-C connector 20 passes through the through hole 13, the first terminal assembly 22 and the second terminal assembly 23 are disposed near the first side 11 of the circuit board 10, and the second end 212 of the housing 21 is disposed near the second side 12 of the circuit board 10.

[0041] Please see Figure 1 , Figure 3 and Figure 4 The electronic device 100 also includes a sealing insulating layer 30, which is disposed on the first side 11 and at least covers the first terminal assembly 22, the second terminal assembly 23, and the through hole 13. By providing the sealing insulating layer 30, the first terminal assembly 22 and the second terminal assembly 23 can be prevented from conducting electricity with other components, and the through hole 13 can be sealed to prevent external moisture, impurities, etc. from entering the interior of the electronic device 100 through the interior of the housing 21 and the through hole 13, thereby improving the reliability of the electronic device 100 in harsh environments. In specific applications, the sealing insulating layer 30 can be formed by applying silicone (or UV adhesive) to the first side 11 of the circuit board 10.

[0042] Please see Figures 3 to 6 The Type-C connector 20 also includes an abutment 24, which is connected to the first end 211 and at least partially protrudes from the outer periphery of the housing 21. The abutment 24 is used to abut against the circuit board 10. Specifically, the abutment 24 abuts against the first side 11 of the circuit board 10. In this way, the Type-C connector 20 can be limited in the thickness direction of the circuit board 10 to prevent the Type-C connector 20 from being pulled out of the through hole 13 during the process of removing the Type-C male connector from the Type-C connector 20, thus preventing the Type-C connector 20 from detaching from the circuit board 10. Therefore, the connection between the Type-C connector 20 and the circuit board 10 is strengthened.

[0043] In one embodiment, the outer shell 21 is formed by metal stamping, and the abutment 24 is connected to the outer shell 21 by secondary injection molding. The abutment 24 is made of plastic material. This arrangement helps to strengthen the connection between the outer shell 21 and the abutment 24, and prevents the outer shell 21 and the abutment 24 from separating when the Type-C male connector is pulled out.

[0044] Please see Figure 1 , Figures 3 to 5 The circuit board 10 also includes a limiting groove 14 formed on the first side 11. A through hole 13 penetrates the bottom wall of the limiting groove 14, and an abutment member 24 abuts against the bottom wall of the limiting groove 14. This arrangement reduces the axial length of the through hole 13, thereby reducing the overall length of the Type-C connector 20 and the circuit board 10 in the length direction of the Type-C connector 20, further reducing the space requirements of the electronic device 100. Furthermore, when applying adhesive to the first side 11 of the circuit board 10 to form the sealing insulating layer 30, the limiting groove 14 can be used as a dispensing groove to form the sealing insulating layer 30. Compared to adding other structural components as dispensing grooves, this reduces costs and saves space. It is understood that in other embodiments, the abutment member 24 may also abut against the first side 11 of the circuit board 10.

[0045] Please see Figure 4 and Figure 5 The Type-C connector 20 includes two abutting members 24, which are spaced apart. A first terminal assembly 22 and a second terminal assembly 23 are disposed between the two abutting members 24. This arrangement, with abutting members 24 on both sides of the first terminal assembly 22 and the second terminal assembly 23, improves the balance of the Type-C connector 20. In this embodiment, each abutting member 24 includes two abutting portions 241, which are spaced apart. Specifically, the limiting groove 14 is rectangular, and the four abutting portions 241 of the two abutting members 24 abut against the four corners of the limiting groove 14. It is understood that in other embodiments, each abutting member 24 may also include one abutting portion 241.

[0046] In one embodiment, the electronic device 100 further includes a first solder layer 41 and a second solder layer 42. The first solder layer 41 connects the first terminal assembly 22 and the first side 11, and the second solder layer 42 connects the second terminal assembly 23 and the first side 11. This arrangement ensures that both the first terminal assembly 22 and the second terminal assembly 23 are electrically connected to the first side 11 of the circuit board 10. The second end 212 of the housing 21 is positioned close to the second side 12 of the circuit board 10, allowing the Type-C connector 20 to be connected to the circuit board 10 using a flip-chip soldering method. Furthermore, the circuit board 10 has through holes 13 for the Type-C connector 20 to pass through, reducing the total length of the Type-C connector 20 and the circuit board 10 in the length direction of the Type-C connector 20 (i.e., the thickness direction of the circuit board 10), saving approximately 2 mm (the sum of 1.6 mm and 0.4 mm) of the circuit board 10 and its solder pads.

[0047] In one embodiment, the shape of the perforation 13 matches the outer contour of the housing 21. This improves the ability of the perforation 13 to limit the housing 21 in both the length and width directions of the circuit board 10. In specific applications, the shape of the perforation 13 can be set to a racetrack shape.

[0048] Please see Figure 1 and Figure 4 The electronic device 100 also includes multiple wires 50. A first side 11 of the circuit board 10 has multiple electrical connection terminals 60 for connecting the wires 50. These terminals are arranged along the edge of the circuit board 10 and correspond one-to-one with each wire 50. In specific applications, the wires 50 have different diameters and bending radii; thicker wires are more difficult to bend. Multiple wires 50 form a wire bundle, which can be located at the central axis of the circuit board 10. By arranging the multiple electrical connection terminals 60 along the edge of the circuit board 10, it is easier to bend and connect thicker wires 50, thus allowing for the connection of more wires 50. It is understood that in other embodiments, the multiple electrical connection terminals 60 can also be arranged in other ways.

[0049] The circuit board 10 also includes multiple first traces (not shown) and multiple second traces (not shown). The first terminal assembly 22 includes multiple first metal terminals 221, and the second terminal assembly 23 includes multiple second metal terminals 231. Each first trace is electrically connected between a first metal terminal 221 and an electrical connection terminal 60, and each second trace is electrically connected between a second metal terminal 231 and an electrical connection terminal 60. This arrangement enables the first terminal assembly 22 and the second terminal assembly 23 to be electrically connected to the wire 50.

[0050] In one embodiment, the circuit board 10 is circular. For the same perimeter, a circle has the largest area, which is advantageous for the design of the electrical connection terminals 60. Of course, in other embodiments, the circuit board 10 can also be configured in other shapes, such as a regular polygon, an ellipse, etc.

[0051] In one embodiment, the electronic device 100 further includes a camera assembly (not shown) electrically connected to the circuit board 10. Thus, the electronic device 100 can have a camera function.

[0052] Furthermore, this embodiment of the invention also provides a vehicle-mounted dashcam (not shown), including the aforementioned electronic device 100. By employing the aforementioned electronic device 100, the space requirements of the electronic device 100 are reduced, which is beneficial for reducing the size of the electronic device 100.

[0053] In this application, the assembly steps of the Type-C connector 20, circuit board 10, and wire 50 are as follows:

[0054] 1) Place the Type-C connector on the first side of the circuit board and align it with the through hole, wherein the first end of the housing is disposed away from the first side and the second end of the housing is disposed towards the first side;

[0055] 2) Move the Type-C connector so that the second end of the housing passes through the perforation;

[0056] 3) The abutment is made to abut against the circuit board, and a plurality of first metal terminals of the first terminal assembly are soldered to the pads of the circuit board by flip-chip soldering process, and a plurality of second metal terminals of the second terminal assembly are soldered to the pads of the circuit board.

[0057] 4) After confirming that the first terminal assembly and the second terminal assembly are electrically connected to the circuit board, apply silicone (or UV adhesive) to the first side of the circuit board to form a sealing insulating layer.

[0058] 5) Solder the wires to the electrical connection terminals one by one.
