Description

Technical Field

[0001] This utility model belongs to the field of connection terminal technology, and in particular relates to a speaker connection terminal. Background Technology

[0002] With the continuous development of miniaturization and integration of electronic devices, the requirements for reliability and stability of interconnects on circuit boards are becoming increasingly stringent. When traditional chip terminals are soldered onto circuit boards, problems such as loose solder joints and breakage are prone to occur, affecting the normal operation and lifespan of the circuit.

[0003] Existing solutions mostly rely on thickening the solder ring, increasing the number of solder joints, or using special solders. However, these methods have limitations in practical applications, such as solder reflow, increased costs, and complex processes. Especially in miniaturized circuit board applications, these methods are difficult to effectively solve the problem of solder joint reliability.

[0004] To overcome the above problems, there is an urgent need for a new, efficient, easy-to-process, and relatively low-cost solution for welding sheet terminals to ensure the strength and reliability of the weld. Utility Model Content

[0005] The purpose of this utility model is to provide a speaker connection terminal, which aims to solve the technical problem that the traditional plate terminals in the prior art are prone to problems such as loosening and breaking of solder joints when soldered on the circuit board, which affects the normal operation and service life of the circuit.

[0006] To achieve the above objectives, this utility model provides a speaker connector terminal, including a terminal body, which comprises a connecting portion, an insertion portion, and a fixing portion. The fixing portion is connected to the insertion portion and the connecting portion at both ends, respectively. The fixing portion is used to fix the terminal body. The connecting portion and the insertion portion are the input and output ends of the terminal body, respectively. The connecting portion is used to connect a power supply component, and the insertion portion is used to connect to another terminal corresponding to the terminal body. The fixing portion includes a fixing plate, and a spring piece is provided on one side of the fixing plate. One end of the spring piece is connected to the fixing plate, and the other end of the spring piece extends towards the connecting portion, forming a snap-fit ​​groove between the spring piece and the fixing plate.

[0007] Furthermore, the fixing plate is also provided with an opening, which is located on one side of the spring piece.

[0008] Furthermore, the connecting part includes a connecting plate, one end of which is connected to the fixing plate, and the other end of the connecting plate is provided with a connecting end, which is connected to the power supply element.

[0009] Furthermore, the connecting end includes a connecting hole and a guide groove. The connecting hole is located on the connecting plate, and the guide groove is located at the end of the connecting plate away from the fixed plate. One end of the guide groove communicates with the connecting hole, and the other end extends to the outside of the connecting plate to form a guide opening.

[0010] Furthermore, the guide groove gradually widens from its connection point with the connecting hole to its connection point with the opening.

[0011] Furthermore, the insertion part includes an insertion plate, one end of which is connected to a fixing plate, and the other end is provided with an insertion end for inserting into a corresponding terminal.

[0012] Furthermore, several protrusions are provided on both sides of the insertion end.

[0013] Furthermore, the end of the insertion plate away from the fixed plate is provided with a guide slope.

[0014] The speaker connector provided in this embodiment of the present invention has at least one of the following technical effects: by setting a spring in the fixing plate, the circuit board is snapped and fixed, solving the problem that the solder joints of the plate terminals are prone to falling off after welding. Its working principle is to pre-embed the spring inside the plate terminal, and before welding, snap it into the corresponding slot of the circuit board. The elasticity of the spring allows the circuit board to be snapped into the slot, and then welding is performed. This effectively avoids gaps and looseness in the solder joints, making the welding more robust and reliable. The specific process is as follows: first, the plate terminal with the spring is snapped into the slot on the circuit board; then, welding is performed using welding equipment; finally, after the electrolyte cools, the spring forms a firm bond with the circuit board.

[0023] In one embodiment of this utility model, reference is made to Figures 1-2As shown, a speaker connector 12 is provided, including a terminal body. The terminal body includes a connecting portion 10, an insertion portion 20, and a fixing portion 30. The two ends of the fixing portion 30 are respectively connected to the insertion portion 20 and the connecting portion 10. The fixing portion 30 is used to fix the terminal body. The connecting portion 10 and the insertion portion 20 are the input and output ends of the terminal body, respectively. The connecting portion 10 is used to connect a power supply component, and the insertion portion 20 is used to connect another terminal corresponding to the terminal body. The fixing portion 30 includes a fixing plate 31. A spring piece 32 is provided on one side of the fixing plate 31. One end of the spring piece 32 is connected to the fixing plate 31, and the other end of the spring piece 32 extends towards the connecting portion 10, forming a snap-fit ​​groove 33 between the spring piece 32 and the fixing plate 31. In this embodiment, by providing the spring piece 32 in the fixing plate 31, the technical effect of snap-fitting and fixing the circuit board is achieved, solving the problem that the solder joints of the sheet terminals are prone to falling off after soldering. Its working principle is to pre-embed the spring contact 32 inside the chip terminal, and then snap it into the corresponding slot on the circuit board before soldering. The elasticity of the spring contact 32 helps the circuit board fit into the slot 33, after which soldering is performed. This effectively avoids gaps and looseness in the solder joints, making the soldering more robust and reliable. The specific process is as follows: First, the chip terminal with the spring contact 32 is snapped into the slot on the circuit board. Then, soldering is performed using soldering equipment. Finally, after the electrolyte cools, the spring contact 32 forms a firm bond with the circuit board.

[0024] Specifically, refer to Figures 1-2 As shown, the fixing plate 31 is also provided with an opening 34, which is located on one side of the spring piece 32.

The connecting hole 13 is disposed on the connecting plate 11, and the guide groove 14 is disposed at the end of the connecting plate 11 away from the fixing plate 31. One end of the guide groove 14 communicates with the connecting hole 13, and the other end extends to the outside of the connecting plate 11 to form a guide opening 3415. The electrical components on the power supply circuit board extend into the connecting hole 13 through the guide groove 14, and then the connecting hole 13 clamps the power supply components, so that the power supply components on the circuit board are electrically connected.

[0027] Specifically, refer to Figures 1-2As shown, the guide groove 14 gradually widens from its connection point with the connecting hole 13 to its connection point with the opening 34. In this embodiment, the guide groove 14 gradually widens from its connection point with the connecting hole 13 to its connection point with the opening 34, facilitating the insertion of the power supply component into the connecting hole 13.

[0028] Specifically, refer to Figures 1-2 As shown, the insertion part 20 includes an insertion plate 21, one end of which is connected to the fixing plate 31, and the other end is provided with an insertion end 22, which is used to extend into the corresponding terminal.
