Description

Technical Field

[0002] With the advancement of science and technology and the development of economy, electronic devices such as mobile phones, tablet computers, headphones, and speakers have become indispensable daily necessities for people. These digital electronic products have been widely integrated into people's daily lives, providing great convenience for people's lives and work, and enriching people's lives. Connectors are one of the indispensable components in electronic products. Most current connectors use Pogo Pins (spring pins) to achieve electrical connection. Pogo Pins include a needle and a needle tube. The needle and the needle tube are connected together by a spring to achieve elasticity and conductive functions. However, the contact area between the needle and the needle tube is small and the impedance is large. When a large current passes through, the temperature of the Pogo Pin will rise rapidly, which may burn the plastic parts next to it and increase the loss of electrical transmission. For example, in the patent document "CN202220000204.5 Multifunctional Beauty Instrument", the circuit board on the beauty head and the circuit board on the beauty instrument body are electrically connected through Pogo pins, which has the technical problem that the contact area between the needle and the needle tube is small and the impedance is large. When a large current passes through, the temperature of the Pogo Pin rises rapidly, which may burn the plastic parts next to it and increase the loss of electrical transmission.

[0028] See also Figures 1 to 4 , an elastic electrical connection component, used for electrical connection between two parts of an electrical device. The elastic electrical connection component includes a first connector 1 and a second connector 2, and the first connector 1 and the second connector 2 are both integral metal structures. The first connector 1 and the second connector 2 are electrically connected when they are in contact with each other or electrically disconnected when they are separated, thereby making the two parts of the electrical device electrically connected or disconnected to achieve the required electrical function. The first connector 1 and the second connector 2 of the elastic electrical connection component are both integral metal structures. The first connector 1 and the second connector 2 of the integral metal structure have good electrical conductivity and generate less heat during operation, which can avoid scalding the plastic parts next to them, and can reduce the loss of electrical transmission and improve the efficiency of electrical transmission. The first connector 1 and the second connector 2 can be stamped and formed using commonly used metal conductive materials such as copper sheets and aluminum sheets.

[0029] See also Figure 1 and Figure 2 , the first connector 1 includes a mounting portion 11, an elastic connecting portion 12, a first abutting portion 13 and a limiting portion 14, and the mounting portion 11 and the first abutting portion 13 are arranged at opposite ends of the elastic connecting portion 12. The mounting portion 11 is used for mounting and fixing the first connector 1 on a structure such as a PCB board. The first abutting portion 13 is used to abut or separate from the second connector 2, thereby realizing an electrical connection or disconnection function. The elastic connecting portion 12 elastically connects the first abutting portion 13 to the mounting portion 11, and the elastic force of the elastic connecting portion 12 realizes that the first abutting portion 13 and the second connector 2 are tightly abutted together, thereby ensuring the reliability of the electrical connection between the first connector 1 and the second connector 2. The limiting portion 14 limits the elastic range of movement of the first abutting portion 13. The limiting portion 14 includes a limiting frame 141 and a limiting arm 142. The limiting frame 141 is arranged on the mounting portion 11, and the limiting arm 142 is arranged at one end of the first abutting portion 13 away from the elastic connecting portion 12. The limiting arm 142 is arranged in the limiting frame 141, so that the limiting arm 142 can only move in the limiting frame 141, and the first abutting portion 13 can only move within a certain range with the limiting arm 142, thereby limiting the first abutting portion 13 within a certain range, avoiding excessive deformation of the elastic connecting portion 12 when the first abutting portion 13 moves, resulting in failure to elastically reset, thereby avoiding damage to the first connecting member 1 and the elastic electrical connecting component and making them unusable, thereby ensuring the reliability and stability of the use of the first connecting member 1.

[0030] See also Figure 1 and Figure 2 In order to optimize the limiting effect of the limiting portion 14 on the first abutting portion 13, it is best to set two groups of the limiting frames 141 and the limiting arms 142, and the two groups of the limiting frames 141 are respectively set on the opposite sides of the mounting portion 11; the two groups of the limiting arms 142 are respectively set on the opposite sides of the extension part of the first abutting portion 13 away from the elastic connecting portion 12, so that each group of limiting arms 142 can be installed in a group of limiting frames 141 respectively, and the two groups of limiting frames 141 limit the two groups of limiting arms 142 on both sides, and the limiting effect of the limiting frames 141 on the limiting arms 142 is better, and the first connecting member 1 is more reliable and stable to use. The two groups of limiting frames 141 can be formed by bending, and are formed by bending from the mounting portion 11 to the elastic connecting portion 12. The holes in the limiting frames 141 can be made by stamping. The outer shape of the inner hole of the limiting frame 141 is larger than that of the limiting arm 142 , so that the limiting arm 142 has a certain range of movement in the limiting frame 141 , and thus the first abutting portion 13 has a certain range of movement.

[0031] See also Figure 1 and Figure 2 The elastic connection part 12 includes a first elastic connection arm 121 and a second elastic connection arm 122, wherein the first elastic connection arm 121 and the second elastic connection arm 122 are elastically connected together, the opposite ends of the first elastic connection arm 121 are respectively connected to the mounting part 11 and the second elastic connection arm 122, and the opposite ends of the second elastic connection arm 122 are respectively connected to the first elastic connection arm 121 and the first abutting part 13, the first elastic connection arm 121 is elastically connected to the mounting part 11, and the second elastic connection arm 122 is elastically connected to the first abutting part 13. Thus, the first elastic connection arm 121 can be elastically movable on the mounting part 11, and the second elastic connection arm 122 can be elastically movable on the first elastic connection arm 121, and the first abutting part 13 has a larger elastic movable range with the elastic connection part 12, and the first abutting part 13 abuts against the second connecting member 2 more tightly and reliably, and the first connecting member 1 is more reliable and stable to use. The first elastic connection arm 121 can be formed by bending a certain angle on the mounting part 11, so that the first elastic connection arm 121 is elastically connected to the mounting part 11. The second elastic connecting arm 122 can be formed by bending the first elastic connecting arm 121 at a certain angle, so that the second elastic connecting arm 122 is elastically connected to the first elastic connecting arm 121 .

[0032] See also Figure 1 to Figure 4The second connecting member 2 includes a first supporting portion 21, a second supporting portion 22, and a second abutting portion 23. The second abutting portion 23 is connected between the first supporting portion 21 and the second supporting portion 22. The first abutting portion 13 can abut against the second abutting portion 23, so that the first connecting member 1 and the second connecting member 2 can be electrically connected by the abutment of the second abutting portion 23 and the first abutting portion 13, or the first connecting member 1 and the second connecting member 2 can be electrically disconnected by the separation of the second abutting portion 23 and the first abutting portion 13. The first supporting portion 21, the second supporting portion 22, and the second abutting portion 23 of the second connecting member 2 are formed by bending the same metal strip.

The surface of the second abutting portion 23 is preferably set as a curved surface structure, and the spherical structure of the conductive convex 131 is in contact with or separated from the curved surface structure of the second abutting portion 23. Therefore, the abutment between the second abutting portion 23 and the first abutting portion 13 is tighter and more reliable, and the electrical connection between the first connecting member 1 and the second connecting member 2 is more reliable. The conductive convex 131 can be stamped on the first abutting portion 13.

[0034] See also Figure 3 and Figure 4 , the first support part 21 is provided with a first pin 211, and the second support part 22 is provided with a second pin 221, so that when the second connector 2 is fixed on a structure such as a circuit board, the first pin 211 and the second pin 221 can be inserted into the corresponding slots on the structure such as the circuit board, and the first pin 211 and the second pin 221 can be welded on the corresponding pads on the structure such as the circuit board, so as to improve the stability of the second connector 2 being fixed on the structure such as the circuit board. The first pin 211 and the second pin 221 are both long sheet structures, and the first pin 211 and the second pin 221 are preferably arranged perpendicular to each other, so that when the first pin 211 and the second pin 221 are inserted into a structure such as a circuit board, they can be installed on the structure such as the circuit board in two mutually perpendicular directions, which can further improve the stability of the second connector 2 being fixed on the structure such as the circuit board.

[0035] See also Figures 1 to 4, the first connector 1 and the second connector 2 of the elastic electrical connection assembly of this embodiment are both formed by stamping metal sheets. When the elastic electrical connection assembly is assembled, the first connector 1 is welded on the pad of the PCB board or other structures through the mounting portion 11, and the second connector 2 is inserted and welded on the circuit board or other structures through the first pin 211 and the second pin 221, and the first connector 1 and the second connector 2 are respectively electrically connected to the two parts of the electrical device. When the elastic electrical connection assembly is used, the first connector 1 and the second connector 2 are electrically connected by the contact between the conductive bump 131 on the first abutting portion 13 and the second abutting portion 23, thereby achieving electrical conduction between the two parts of the electrical device; the first connector 1 and the second connector 2 are electrically disconnected by the separation of the conductive bump 131 on the first abutting portion 13 and the second abutting portion 23, thereby achieving electrical disconnection between the two parts of the electrical device.
