DETAILED DESCRIPTION

[0037] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0039] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0040] It should be noted that, for the convenience of explanation, in the embodiments of the present application, the same figure marks represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments.

[0041] The grounding pad on the circuit board of the driver power supply usually needs to be drilled with screw holes, and then the screws are manually installed with an electric screwdriver to screw the circuit board and the housing of the driver power supply together, thereby grounding the grounding pad of the circuit board. This greatly increases the labor cost of preparing the driver power supply.

[0042] See also Figure 1 The embodiment of the present application provides an electrical connector 100, which includes a first electrical connector 10, a first plug connector 20, and a second electrical connector 30. The first plug connector 20 is disposed on one side of the first electrical connector 10 and connected to the first electrical connector 10, the first plug connector 20 includes a first body 21 and a first protruding portion 22, and the first protruding portion 22 is protruding from the surface of the first body 21; the second electrical connector 30 is bent and connected to the first electrical connector 10, and the second electrical connector 30 and the first plug connector 20 are respectively disposed on two adjacent sides of the first electrical connector 10.

[0043] The electrical connector 100 of the embodiment of the present application may be, but is not limited to, a grounding spring or other spring used to electrically connect two components.

[0044] The electrical connector 100 of the embodiment of the present application can be applied to a driving power supply, which includes a circuit board assembly and a housing. The circuit board assembly includes an electrically connected circuit board and a grounding pad. The grounding pad is arranged on one side of the circuit board. The grounding pad is used for grounding. The grounding pad has a plug hole. The first plug-in portion 20 of the electrical connector 100 is used to be plugged into the plug hole, and the second electrical connection portion 30 is used to abut against the housing so that the grounding pad is electrically connected to the housing, thereby achieving grounding.

[0045] During assembly, the first plug-in portion 20 of the electrical connector 100 is first inserted into the plug-in hole, and then the circuit board assembly with the electrical connector 100 inserted therein is passed through a tin furnace to connect the side of the first plug-in portion 20 away from the first electrical connector 10 to the ground pad through soldering. Then the circuit board assembly with the electrical connector 100 is inserted into the housing, and the end of the second electrical connector 30 close to the first electrical connector 10 is inserted first, and the end of the second electrical connector 30 away from the first electrical connector 10 is inserted later. During the insertion process, the second electrical connector 30 will be elastically bent compared to the first electrical connector 10, and under the action of the elastic restoring force of the second electrical connector 30, the second electrical connector 30 stably abuts against the housing, thereby achieving a stable electrical connection.

[0046] In a specific embodiment, the first protruding portion 22 and the second electrical connection portion 30 are disposed opposite to the first electrical connection portion 10. It can be understood that the second electrical connection portion 30 is bent in a direction away from the first protruding portion 22 compared to the first electrical connection portion 10.

[0047] It should be noted that the first electrical connection part 10, the first plug part 20 and the second electrical connection part 30 are an integrated structure, and the first electrical connection part 10, the first plug part 20 and the second electrical connection part 30 are different parts of the same component. The electrical connector 100 can be formed using a flat plate by bending, stamping and other processes.

[0048] The electrical connector 100 of the embodiment of the present application includes a first electrical connector 10, a first plug-in connector 20 and a second electrical connector 30. The first plug-in connector 20 is disposed on one side of the first electrical connector 10 and connected to the first electrical connector 10. The first plug-in connector 20 includes a first body 21 and a first protruding portion 22. The first protruding portion 22 is protruding from the surface of the first body 21. The second electrical connector 30 is connected to the first electrical connector 10 by bending. The second electrical connector 30 and the first plug-in connector 20 are respectively disposed on adjacent sides of the first electrical connector 10. When the electrical connector 100 of the embodiment of the present application is applied to a driving power supply, it is only necessary to insert the first plug-in connector 20 into the plug-in hole of the circuit board assembly of the driving power supply so that the second electrical connector 30 abuts against the housing of the driving power supply to achieve installation. Compared with the solution of fixing with screws, the plug-in process greatly reduces the assembly time, improves the assembly efficiency of the driving power supply, and reduces the assembly cost of the driving power supply. In addition, the first plug-in portion 20 includes a first body portion 21 and a first protrusion 22 protruding from the first body portion 21. By providing the first protrusion 22, the first plug-in portion 20 can better resist the circuit board assembly when plugged into the plug hole of the circuit board assembly, so that the first plug-in portion 20 can be more firmly plugged into the circuit board assembly, so that the electrical connector 100 can better electrically connect to the ground pad of the circuit board assembly. In addition, if screws are used for fixing, a large space margin is required around the ground pad if automated assembly is to be achieved, otherwise the circuit on the circuit board assembly is easily damaged when the screws are assembled; while the electrical connector of the present application is assembled by plug-in, and there is no requirement for the reserved space on the circuit board assembly, so that the plug-in can be performed by a machine to achieve automation, which greatly improves the assembly efficiency of the electrical connector 100.

[0049] See also Figure 2 In some embodiments, the electrical connector 100 also includes a second plug-in portion 40, which is arranged on a side of the first electrical connector 10 away from the first plug-in portion 20; the second plug-in portion 40 includes a second main body portion 41 and a second protruding portion 42, and the second protruding portion 42 is protruded from the surface of the second main body portion 41.

[0050] It can be understood that the first plug-in portion 20 and the second plug-in portion 40 are relatively arranged on opposite sides of the first electrical connection portion 10, and along the arrangement direction of the first plug-in portion 20, the first electrical connection portion 10 and the second plug-in portion 40, the second electrical connection portion 30 is located between the first plug-in portion 20 and the second plug-in portion 40.

[0051] In a specific embodiment, the second protruding portion 42 and the second electrical connecting portion 30 are disposed opposite to each other.

[0052] Optionally, the first protruding portion 22 and the second protruding portion 42 are disposed on the same side of the first electrical connection portion 10. In other words, the first protruding portion 22 and the second protruding portion 42 protrude toward the same side relative to the first electrical connection portion 10.

[0053] In this embodiment, by providing the second plug-in portion 40 on the side of the first electrical connection portion 10 away from the first plug-in portion 20, the adaptability of the electrical connector 100 can be better increased, so that the electrical connector 100 can be mounted on the left or right side of the circuit board assembly (i.e., it can be inserted forward or backward), and the second electrical connector 30 can stably abut the housing of the driving power supply, so that the first electrical connector 100 can match the use requirements of different positions of the circuit board of the driving power supply, thereby reducing the material specifications of the driving power supply. In addition, when the circuit board assembly is assembled in the housing, the circuit board assembly is usually inserted into the housing from one side, so that when the two opposite sides of the circuit board assembly perpendicular to the insertion direction have grounding pads, there is no need to prepare two mirrored electrical connectors 100, and only the electrical connector 100 of this embodiment needs to be used, and the grounding pads on both sides of the circuit board assembly can be used, thereby improving the versatility and adaptability of the electrical connector 100.

[0054] See also Figure 3 In some embodiments, the size of the first protrusion 22 gradually decreases from the end of the first protrusion 22 connected to the first main body 21 toward the direction away from the first main body 21; the size of the second protrusion 42 gradually decreases from the end of the second protrusion 42 connected to the second main body 41 toward the direction away from the second main body 41.

[0055] In this embodiment, the size of the first protrusion 22 is gradually reduced, and the size of the second protrusion 42 is gradually reduced; in this way, when the first plug-in portion 20 or the second plug-in portion 40 is inserted into the plug-in hole or the through hole of the circuit board assembly, it can be better inserted into the plug-in hole or the through hole, and the first plug-in portion 20 or the second plug-in portion 40 can also better support the circuit board assembly, so as to better electrically connect the ground pad of the circuit board assembly.

[0056] Optionally, the end surface of the first protrusion 22 facing away from the first main body portion 21 is a plane, and the end surface of the second protrusion 42 facing away from the second main body portion 41 is a plane. In this way, when the first plug-in portion 20 is plugged into the plug-in hole and the second plug-in portion 40 is plugged into the through hole, they can have a larger contact area with the grounding pad, thereby improving the stability of the electrical connection between the electrical connector 100 and the grounding pad.

[0057] Optionally, the height h1 of the first protrusion 22 ranges from 0.5 mm to 0.8 mm. Specifically, the height of the first protrusion 22 may range from, but is not limited to, 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm, 0.7 mm, 0.75 mm, 0.8 mm, etc. If the height of the first protrusion 22 is too small, the stability of the electrical connection between the first plug-in portion 20 and the circuit board assembly is reduced when the electrical connector 100 is applied to the driving power supply. If the height of the first protrusion 22 is too large, the difficulty of inserting the first plug-in portion 20 into the plug hole is increased.

[0058] Optionally, the width w1 of the first protrusion 22 ranges from 1.5 mm to 2.0 mm. Specifically, the width of the first protrusion 22 may be, but is not limited to, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2.0 mm, etc.

[0059] Optionally, the height h2 of the second protrusion 42 ranges from 0.5 mm to 0.8 mm. Specifically, the height of the second protrusion 42 may be, but is not limited to, 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm, 0.7 mm, 0.75 mm, 0.8 mm, etc. If the height of the second protrusion 42 is too small, the stability of the electrical connection between the second plug-in portion 40 and the circuit board assembly is reduced when the electrical connector 100 is applied to the driving power supply. If the height of the second protrusion 42 is too large, the difficulty of inserting the second plug-in portion 40 into the through hole is increased.

[0060] Optionally, the width w2 of the second protrusion 42 ranges from 1.5 mm to 2.0 mm. Specifically, the width of the second protrusion 42 may be, but is not limited to, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2.0 mm, etc.

[0061] In some embodiments, the number of the first plug-in portions 20 is two, and the two first plug-in portions 20 are arranged at intervals along the extension direction of the side of the first electrical connection portion 10 .

[0062] In a specific embodiment, the number of the first plug-in portions 20 is two, and the number of the second plug-in portion 40 is one.

[0063] In this embodiment, two first plug-in parts 20 are provided, and there is only one second plug-in part 40 on the other side, so that better anti-mistakes can be performed. When the electrical connector 100 is installed on the driving power supply, when installation is required on both sides of the circuit board assembly, better identification and anti-mistakes can be performed, thereby improving the installation efficiency of the electrical connector 100 and further improving the assembly efficiency of the driving power supply.

[0064] Please also see Figures 3 to 5In some embodiments, the electrical connector 100 further includes a third electrical connector 50, which is disposed on a side of the first electrical connector 10 away from the second electrical connector 30, and the third electrical connector 50 is bent and connected to the first electrical connector 10, and the second electrical connector 30 and the third electrical connector 50 are bent in opposite directions compared to the first electrical connector 10.

[0065] It should be noted that the first protruding portion 22 , the second protruding portion 42 and the third electrical connection portion 50 are all located on the same side of the first electrical connection portion 10 , and the second electrical connection portion 30 is located on the other side of the first electrical connection portion 10 .

[0066] In this embodiment, by providing a third electrical connection portion 50 and making the third electrical connection portion 50 and the second electrical connection portion 30 bend in opposite directions compared to the first electrical connection portion 10, when the first plug-in portion 20 or the second plug-in portion 40 is inserted into the circuit board assembly, the electrical connector 100 is not prone to tilt or skew, thereby enabling the electrical connector 100 to be more stably electrically connected to the circuit board assembly and the housing.

[0067] Optionally, the range of the angle γ between the first electrical connection portion 10 and the third electrical connection portion 50 is 60°≤γ≤150°. Specifically, the angle γ between the first electrical connection portion 10 and the third electrical connection portion 50 may be, but is not limited to, 60°, 70°, 80°, 90°, 100°, 110°, 115°, 120°, 125°, 130°, 140°, 150°, etc. If the angle γ between the first electrical connection portion 10 and the third electrical connection portion 50 is too small or too large, when the electrical connector 100 is plugged into the circuit board assembly, the electrical connector 100 is easily tilted toward the side away from the second electrical connection portion 30, which is not conducive to improving the stability of the electrical connector 100 plugged into the circuit board assembly.

[0068] Optionally, along the arrangement direction of the first electrical connection part 10 and the third electrical connection part 50, the length L1 of the third electrical connection part 50 is in the range of 1.8mm≤L1≤2.5mm. Specifically, along the arrangement direction of the first electrical connection part 10 and the third electrical connection part 50, the length L1 of the third electrical connection part 50 may be, but is not limited to, 1.8mm, 1.9mm, 2.0mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, etc. In the embodiment of the present application, along the arrangement direction of the first electrical connection part 10 and the third electrical connection part 50, if the length L1 of the third electrical connection part 50 is too small, the electrical connector 100 is easily tilted when plugged into the circuit board assembly, and the improvement of the stability of the electrical connector 100 is limited; along the arrangement direction of the first electrical connection part 10 and the third electrical connection part 50, if the length L1 of the third electrical connection part 50 is too large, the material cost is increased.

[0069] See also Figure 5 In some embodiments, the second electrical connection portion 30 includes a first electrical connection sub-portion 31, a second electrical connection sub-portion 32 and a third electrical connection sub-portion 33 which are bent and connected in sequence, the first electrical connection sub-portion 31 is bent and connected to the first electrical connection portion 10, the first electrical connection portion 10 and the second electrical connection sub-portion 32 are bent in opposite directions compared to the first electrical connection sub-portion 31, and the first electrical connection sub-portion 31 and the third electrical connection sub-portion 33 are bent in opposite directions compared to the second electrical connection sub-portion 32.

[0070] In this embodiment, the second electrical connection portion 30 includes a first electrical connection sub-portion 31, a second electrical connection sub-portion 32 and a third electrical connection sub-portion 33 which are bent and connected in sequence. The first electrical connection sub-portion 31 and the second electrical connection sub-portion 32 can make the second electrical connection portion 30 have better elasticity and resilience. The third electrical connection sub-portion 33 can increase the contact area between the second electrical connection portion 30 and the shell. When the electrical connector 100 is plugged into the circuit board assembly and the circuit board assembly is thereby inserted into the shell from the side, the second electrical connection portion 30 of the electrical connector 100 can better resist the shell and better make electrical connection with the shell.

[0071] In some embodiments, the angle α between the first electrical connection portion 10 and the first electrical connection sub-portion 31 is in the range of 110°≤α≤170°.

[0072] Specifically, the angle α between the first electrical connection portion 10 and the first electrical connection sub-portion 31 may be, but is not limited to, 110°, 115°, 120°, 125°, 130°, 140°, 150°, 160°, 170°, etc. If the angle α between the first electrical connection portion 10 and the first electrical connection sub-portion 31 is too small, when the electrical connector 100 is installed on the driving power supply, the second electrical connection portion 30 has insufficient resilience and cannot well support the housing of the driving power supply, thereby causing the electrical connection between the electrical connector 100 and the housing to be easily loosened.

[0073] Optionally, the angle β between the second electrical connection sub-portion 32 and the third electrical connection sub-portion 33 is in the range of 120°≤β≤160°.

[0074] Specifically, the angle β between the second electrical connection sub-portion 32 and the third electrical connection sub-portion 33 may be, but is not limited to, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, etc. If the angle β between the second electrical connection sub-portion 32 and the third electrical connection sub-portion 33 is too small, the elasticity of the second electrical connection portion 30 is reduced, which is not conducive to the electrical connection between the second electrical connection portion 30 and the housing; if the angle β between the second electrical connection sub-portion 32 and the third electrical connection sub-portion 33 is too large, when the electrical connector 100 is installed on the housing, the contact area between the third electrical connection sub-portion 33 and the housing is reduced, which is not conducive to the stability of the electrical connection between the electrical connector 100 and the housing.

[0075] Optionally, the angle θ between the first electrical connection sub-portion 31 and the second electrical connection sub-portion 32 is in the range of 140°≤θ≤170°.

[0076] Specifically, the angle θ between the first electrical connection sub-portion 31 and the second electrical connection sub-portion 32 may be, but is not limited to, 140°, 145°, 150°, 155°, 158°, 160°, 165°, 170°, etc. If the angle θ between the first electrical connection sub-portion 31 and the second electrical connection sub-portion 32 is too small or too large, the elasticity of the second electrical connection portion 30 will be reduced, thereby affecting the stability of the connection between the electrical connection member 100 and the housing when the electrical connection member 100 is applied to a driving power source.

[0077] Optionally, along the arrangement direction of the first electrical connection portion 10 and the second electrical connection portion 30, the length L2 of the second electrical connection portion 30 is in the range of 5mm≤L2≤6.5mm. Specifically, along the arrangement direction of the first electrical connection portion 10 and the third electrical connection portion 50, the length L1 of the third electrical connection portion 50 may be, but is not limited to, 5mm, 5.1mm, 5.2mm, 5.3mm, 5.4mm, 5.5mm, 5.6mm, 5.7mm, 5.8mm, 5.9mm, 6.0mm, 6.1mm, 6.2mm, 6.3mm, 6.4mm, 6.5mm, etc. In the embodiment of the present application, along the arrangement direction of the first electrical connection part 10 and the second electrical connection part 30, the length L2 of the second electrical connection part 30 is too small, so the electrical connector 100 is easily tilted when plugged into the circuit board assembly, which has limited effect on improving the stability of the electrical connector 100, and the elasticity and resilience of the second electrical connection part 30 will also be reduced, thereby reducing the stability of the connection between the electrical connector 100 and the housing; along the arrangement direction of the first electrical connection part 10 and the second electrical connection part 30, the length L2 of the second electrical connection part 30 is too large, which increases the material cost, and the installation of the electrical connector 100 requires a larger space, which is not conducive to the miniaturization of the driving power supply.

[0078] Optionally, the thickness of the first electrical connection portion 10 is in the range of 0.18 mm to 0.22 mm. The thickness of the second electrical connection portion is in the range of 0.18 mm to 0.22 mm. The thickness of the third electrical connection portion 50 is in the range of 0.18 mm to 0.22 mm. The thickness of the first body portion 21 is in the range of 0.18 mm to 0.22 mm. The thickness of the second body portion 41 is in the range of 0.18 mm to 0.22 mm.

[0079] See also Figures 6 to 9 The embodiment of the present application also provides a driving power supply 200, which includes a circuit board assembly 210, the electrical connector 100 described in the embodiment of the present application, and a housing 220. The circuit board assembly 210 includes a circuit board 211 and a grounding pad 212, the grounding pad 212 is arranged near the outer periphery of the circuit board 211, the grounding pad 212 is used for grounding, and the grounding pad 212 has a plug hole 2121; the first plug-in portion 20 of the electrical connector 100 is plugged into the plug hole 2121, so that the first plug-in portion 20 is electrically connected to the grounding pad 212; the housing 220 has a receiving cavity 221, the circuit board assembly 210 and the electrical connector 100 are installed in the receiving cavity 221, and the second electrical connecting portion 30 of the electrical connector 100 abuts against the housing 220, so that the second electrical connecting portion 30 is electrically connected to the housing 220.

[0080] Optionally, the driving power supply 200 may be, but is not limited to, a light emitting diode driving power supply (LED driving power supply for short). The LED driving power supply is a power converter that converts the power supply into a specific voltage and current to drive the LED to emit light. Usually, the input of the LED driving power supply includes high-voltage industrial frequency AC (i.e., mains), low-voltage DC, high-voltage DC, low-voltage high-frequency AC (such as the output of an electronic transformer), etc.

[0081] It should be noted that the housing 220 is a conductor, that is, the housing 220 is made of a conductive material. Specifically, the housing 220 may be made of, but not limited to, aluminum, aluminum alloy, stainless steel, and the like.

[0082] The driving power supply 200 of the present application includes an electrical connector 100, and the electrical connector 100 includes a first electrical connector 10, a first plug connector 20, and a second electrical connector 30. The first plug connector 20 is disposed on one side of the first electrical connector 10 and connected to the first electrical connector 10, and the first plug connector 20 includes a first body 21 and a first protruding portion 22, and the first protruding portion 22 is protruding on the surface of the first body 21; the second electrical connector 30 is connected to the first electrical connector 10 by bending, and the second electrical connector 30 and the first plug connector 20 are respectively disposed on two adjacent sides of the first electrical connector 10. When the electrical connector 100 is assembled to the driving power supply 200, it is only necessary to insert the first plug-in portion 20 into the plug-in hole 2121 of the circuit board assembly 210 of the driving power supply 200, and to make the second electrical connector 30 abut against the housing 220 of the driving power supply 200 to achieve installation. Compared with the solution of fixing with screws, the plug-in process greatly reduces the assembly time, improves the assembly efficiency of the driving power supply 200, and reduces the assembly cost of the driving power supply 200. In addition, the first plug-in portion 20 includes a first body portion 21 and a first protruding portion 22 protruding from the first body portion 21. By providing the first protruding portion 22, when the first plug-in portion 20 is plugged into the plug-in hole 2121 of the circuit board assembly 210, it can better abut against the circuit board assembly 210, so that the first plug-in portion 20 is more firmly plugged into the circuit board assembly 210, so that the electrical connector 100 is better electrically connected to the ground pad 212 of the circuit board assembly 210. In addition, when fixing with screws, if automated assembly is to be achieved, a large space margin is required around the ground pad 212, otherwise the circuit on the circuit board assembly 210 is easily damaged when the screws are assembled; the electrical connector of the present application is assembled by plug-in, and there is no requirement for reserved space on the circuit board assembly 210, so that a machine can be used for plug-in to achieve automation, which greatly improves the assembly efficiency of the electrical connector 100.

[0083] See also Fig.10In some embodiments, the housing 220 includes a first side wall 222 and a second side wall 223 that are arranged back to back; the first side wall 222 has a first card slot 2221 facing the receiving cavity 221, and the second side wall 223 has a second card slot 2231 facing the receiving cavity 221, and the opposite ends of the circuit board assembly 210 are respectively inserted into the first card slot 2221 and the second card slot 2231.

[0084] It can be understood that the first card slot 2221 and the second card slot 2231 are arranged to face each other, and the first card slot 2221 and the second card slot 2231 are both connected to the receiving cavity 221 .

[0085] Optionally, the first card slot 2221 is parallel to the second card slot 2231 , and both the first card slot 2221 and the second card slot 2231 extend along an extension direction of the housing 220 .

[0086] During assembly, the electrical connector 100 is inserted into the plug hole 2121 of the circuit board assembly 210. At this time, the second electrical connector 30 at least partially protrudes from the circuit board assembly 210. When the circuit board assembly 210 is installed in the housing 220, it is only necessary to insert the circuit board assembly 210 with the electrical connector 100 into the first card slot 2221 and the second card slot 2231 from the opening of the receiving cavity 221, and make the end of the second electrical connector 30 closer to the first electrical connector 10 enter the receiving cavity 221 more than the end of the second electrical connector 30 away from the first electrical connector 10. During the process of inserting the circuit board assembly 210 into the receiving cavity 221, the second electrical connector 30 is squeezed and elastically deformed (bent), and under the action of the elastic restoring force, it always presses against the first side wall 222 and the second side wall 223, so that the electrical connector 100 is always electrically connected to the housing 220.

[0087] In this embodiment, by providing the first slot 2221 and the second slot 2231 on the housing 220, the opposite ends of the circuit board 211 are respectively provided in the first slot 2221 and the second slot 2231, so that the circuit board assembly 210 can be fixed in the housing 220 to prevent the circuit board assembly 210 from shaking in the housing 220. In addition, before the electrical connector 100 is assembled in the housing 220, the second electrical connection portion 30 protrudes out of the circuit board assembly 210. As long as there is a little elastic force, the second electrical connection portion 30 can contact with the first side wall 222 or the second side wall 223 to achieve a grounding effect. During assembly, the circuit board assembly 210 with the electrical connector 100 only needs to be gently pushed into the housing 220 to achieve electrical connection between the housing 220 and the electrical connector 100, so that there is no need to manually screw, which achieves the purpose of convenient and fast installation.

[0088] Optionally, the circuit board 211 also includes a grounding portion 213, and the grounding portion 213 has a penetration hole 2131. The penetration hole 2131 is located on the side of the circuit board 211 away from the plug hole 2121. The penetration hole 2131 is used to penetrate the second plug-in portion 40 of another electrical connector 100 so as to electrically connect the grounding portion 213 to the second plug-in portion 40.
