The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0051] Some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0052] See also Figures 1 to 9The present embodiment provides a circuit board 1, comprising a board 11, an electronic component 12 and an insulating component 13. The electronic component 12 comprises a body 123, a first pin 121 and a second pin 122 spaced apart along a first direction 14, the first pin 121 and the second pin 122 being electrically connected to the body 123, and the body 123 being connected to the board 11 through the first pin 121 and the second pin 122. The insulating component 13 comprises an isolating portion 131, and the isolating portion 131 is disposed between the first pin 121 and the second pin 122. The first pin 121, the second pin 122, and the isolating portion 131 may be spaced apart from each other and may extend perpendicularly to the board 11 or the first direction 14. The length of the isolating portion 131 protruding from the surface of the board 11 along the thickness direction of the board 11 is greater than the length of the first pin 121 and the second pin 122 protruding from the surface of the board 11. The thickness direction may be perpendicular to the first direction 14 or the second direction 15.

[0053] The circuit board 1 provided in the embodiment is provided with an isolating portion 131 protruding from the surface of the board 11 with a length greater than a length of the first pin 121 and the second pin 122 protruding from the surface of the board 11, so that the electrical gap between the first pin 121 and the second pin 122 is increased, thereby increasing the breakdown voltage between the first pin 121 and the second pin 122, thereby improving the insulation performance of the first pin 121 and the second pin 122 of the circuit board 1.

[0054] Please combine Figure 1 and Figure 2 As shown, in the first embodiment, the electronic component 12 may be a relay, or a chip or other electronic components.

[0055] The first pin 121 is an input end of the electronic component 12 , and the second pin 122 is an output end of the electronic component 12 .

[0056] The isolation part 131 can be made of rubber material. The isolation part 131 has a large resistance. By setting the isolation part 131 between the first pin 121 and the second pin 122, the length of the isolation part 131 protruding from the surface of the plate 11 is greater than the length of the first pin 121 and the second pin 122 protruding from the surface of the plate 11, so that the electrical gap between the first pin 121 and the second pin 122 is increased to prevent the first pin 121 and the second pin 122 from being broken down by voltage.

[0057] In one embodiment, the board 11 defines a through hole 111, the through hole 111 is disposed between the first pin 121 and the second pin 122, and the isolation portion 131 passes through the through hole 111. The isolation portion 131 can be separated from the board 11.

[0058] In this embodiment, the through hole 111 extends along the thickness direction of the plate portion to prevent the first pin 121 and the second pin 122 from being connected through the plate 11, which is beneficial to improving the insulation performance of the first pin 121 and the second pin 122. The isolation portion 131 extends to the through hole 111 to further increase the insulation performance between the first pin 121 and the second pin 122.

[0059] In one embodiment, the cross section of the through hole 111 is an elongated strip. The through hole 111 extends along the second direction 15 to the outside of the first pin 121 and the second pin 122 . The second direction 15 is perpendicular to the first direction 14 .

[0060] In this embodiment, the first direction 14 is the width direction of the through hole 111, and the second direction 15 is the length direction of the through hole 111. The first pin 121 and the second pin 122 are respectively disposed on both sides of the long strip through hole 111 along the first direction 14, and the insulating member 13 extends along the long strip through hole 111 to block the first pin 121 and the second pin 122.

[0061] Optionally, there may be multiple first pins 121 and multiple second pins 122, and the multiple first pins 121 and multiple second pins 122 are separated by the long strip through hole 111 on both sides of the long strip through hole 111. The insulating member 13 extends along the second direction 15 to block the first pin 121 and the second pin 122.

[0062] See also Figure 3 and Figure 4 In the second embodiment, the insulating member 13 further includes a first extension portion 132, the first extension portion 132 is connected to an end of the isolation portion 131 away from the body 123, and the first extension portion 132 extends along the first direction 14 toward the second pin 122. In other words, the first extension portion 132 extends parallel to the board 11 and is separated from the board 11.

[0063] In the second embodiment, the isolation portion 131 extends from one side of the board 11 to the other side of the board 11 through the through hole 111, and the height of the isolation portion 131 protruding from the surface of the board 11 is greater than the height of the first pin 121 and the second pin 122 protruding from the surface of the board 11. The extended length of the first extension portion 132 further increases the electrical gap between the second pin 122 and the first pin 121, so as to further improve the breakdown voltage between the first pin 121 and the second pin 122.

[0064] The plate 11, the isolation portion 131 and the first extension portion 132 form a filling space 16, and the second pin 122 extends into the filling space 16. The insulating member 13 further includes a colloid 134, which fills the filling space 16 and wraps the second pin 122. In other words, the colloid 134 can wrap the top and side surface of the second pin 122.

[0065] In this embodiment, the colloid 134 is coated on the second pin 122 to wrap the surface of the second pin 122. The colloid 134 can extend to the surface of the isolation portion 131 and the first extension portion 132 to help fix the shape of the colloid 134, so that the second pin 122 is covered in the filling space 16.

[0066] Please combine Figure 5 and Figure 6 As shown, in the third embodiment, the insulating member 13 also includes a second extension portion 133, a third extension portion 135 and a fourth extension portion 136. The second extension portion 133 and the third extension portion 135 are arranged on opposite sides of the plate 11, and the fourth extension portion 136 and the isolation portion 131 are arranged on both sides of the first pin 121 along the first direction 14. One end of the isolation portion 131 is connected to the second extension portion 133, and the other end is connected to the third extension portion 135. The fourth extension portion 136 is connected to the ends of the second extension portion 133 and the third extension portion 135. The isolation portion 131, the second extension portion 133, the third extension portion 135 and the fourth extension portion 136 form a rectangular frame structure.

[0067] In this embodiment, the rectangular frame structure has good strength and is not easily deformed, so that the isolation member can be firmly connected to the plate member 11, thereby preventing the insulation member 13 from deforming and displacing during use, thereby preventing the insulation performance from being reduced.

[0068] A evacuation notch 1351 for evacuating the body 123 is defined at a middle position of the third extension portion 135 along the second direction 15 .

[0069] In this embodiment, the avoidance notch 1351 is used to allow the insulating member 13 to be wrapped around the first pin 121 , which is beneficial for the stable connection between the insulating member 13 and the board 11 .

[0070] The main body 123 is connected to the lower surface of the board 11, and the first pin 121 and the second pin 122 pass through the board 11 along the thickness direction of the board 11 to the other side surface of the board 11. The height of the isolation portion 131 extending along the thickness direction of the board 11 is greater than the protruding height of the first pin 121 along the thickness direction of the board 11.

[0071] In this embodiment, one side of the board 11 is used to connect to the body 123, and the other side is used to set the wires of the board 11. The first pin 121 and the second pin 122 pass through the board 11 along the thickness direction of the board 11 from one side of the board 11 close to the body 123 to connect to the wires of the other side.

[0072] The foregoing Figure 3 and Figure 4 The embodiment shown is suitable for the case where the insulating member 13 is arranged inside the plate member 11, and Figure 5 and Figure 6 The illustrated embodiment is suitable for a case where the insulating member 13 is arranged on a side of the plate member 11 .

[0073] Please combine Figure 7 As shown, in the fourth embodiment, the body 123, the first pin 121 and the second pin 122 are connected to the same side of the board 11, and the height of the isolation portion 131 extending along the thickness direction of the board 11 is greater than the protruding height of the first pin 121 along the thickness direction of the board 11.

[0074] In this embodiment, the first pin 121 and the second pin 122 may not penetrate the board 11 , and the circuit, the body 123 , the first pin 121 and the second pin 122 of the board 11 are arranged on the same side of the board 11 .

[0075] The insulating member 13 also includes a fifth extension portion 137 and a sixth extension portion 138, and the fifth extension portion 137 and the sixth extension portion 138 are respectively connected to two ends of the insulating member 13, the fifth extension portion 137 extends along the first direction 14 toward the first pin 121, and the sixth extension portion 138 extends along the first direction 14 toward the second pin 122, and the sixth extension portion 138 is connected to the plate 11.

[0076] In this embodiment, the isolation portion 131 of the insulating member 13 passes through the plate 11 and extends to both sides of the plate 11, and the fifth extension portion 137 extends to the top of the first pin 121 to increase the breakdown voltage between the first pin 121 and the second pin 122. The sixth extension portion 138 extends to the side of the plate 11 away from the body 123 and is connected to the side of the plate 11, which is conducive to fixing the insulating member 13.

[0077] See also Figure 8 and Fig. 9 In the fifth embodiment, in this embodiment, Figure 3 and Figure 4 On the basis of the present invention, the adhesive material 134 is abandoned, and the first bonding part 1391 connected to the first extension part 132 is bonded to the surface of the side of the plate 11 away from the electronic part 12, and the second bonding part 1392 connected to the isolation part 131 is bonded to the surface of the side of the plate 11 close to the electronic part 12.

[0078] In summary, the circuit board 1 increases the electrical gap between the first pin 121 and the second pin 122 by setting the length of the insulating member 13 protruding from the surface of the board 11 to be greater than the length of the first pin 121 and the second pin 122 protruding from the surface of the board 11, thereby increasing the breakdown voltage between the first pin 121 and the second pin 122.
