[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] like Figure 1 As shown, this embodiment provides a terminal block, including a conductor and a fixing member. The conductor is used for electrical connection with a circuit board. The conductor is provided with a card interface, which includes a first contact surface 1 and a second contact surface 2. The fixing member is snapped into the card interface and forms a clamping space with the first contact surface 1 and the second contact surface 2 to clamp and fix the power cord, so that the conductor is electrically connected to the power cord. From the direction of the card interface toward the fixing member, the distance between the first contact surface 1 and the second contact surface 2 gradually increases, so that the clamping space fixes the power cord more stably and avoids the power cord from shaking in the clamping space, causing the power cord to fall off or the circuit to fail.

[0029] The conductor is electrically connected to the circuit board, enabling circuit connection between the terminal block and the circuit board; the fastener and the card interface form a clamping space to fix the power cord, making the conductor and the power cord electrically connected, thus realizing the quick connection between the power cord and the circuit board; the fastener is set in the card interface in a snap-fit ​​connection manner, which can realize quick connection and simplify the installation process.

[0030] The first contact surface 1 and the second contact surface 2 can be planar or curved. The first contact surface 1 and the second contact surface 2 can be axially symmetrical about the direction of the self-locking interface toward the fixing member, or an asymmetrical structure can be selected according to the actual use, so that the power line is deviated from one of the first contact surface 1 or the second contact surface 2.

[0031] In a more specific embodiment, in order to further improve the contact effect between the conductor and the power line and improve the stability of power transmission, a first elastic opening 3 is provided on the side of the first contact surface 1 and the second contact surface 2 away from the fixing member.

[0032] The first elastic opening 3 can be a gap extending away from the connection position of the first contact surface 1 and the second contact surface 2 in a direction away from the fastener.

[0033] More specifically, in the direction of the self-card interface facing the fixing member, the projection of the inner wall of the first elastic port 3 is a smooth curve connecting the first contact surface 1 and the second contact surface 2. Its shape is similar to a U-shape or a teardrop shape, so as to prevent the side of the first elastic port 3 away from the fixing member from being torn when the card interface is squeezed by the limiting post and the power line.

[0034] In a more specific embodiment, to further improve the elastic deformation space of the card interface, enhance its adaptability to power cables of different diameters, and improve the clamping stability of the power cable, second elastic openings 5 ​​extending towards the first elastic opening 3 are provided on both sides of the conductor from the card interface toward the fixing member. The second elastic opening 5 includes a first side 51 and a second side 52, with the first side 51 and the second side 52 connected at their ends facing the first elastic opening 3. The distance between the first side 51 and the second side 52 decreases along the edge of the conductor toward the first elastic opening 3. Specifically, the shape of the second elastic opening 5 can be V-shaped or U-shaped. In this specific embodiment, the angle between the first side 51 and the second side 52 is 45 degrees, wherein the second side 52 is perpendicular to the extending direction of the first elastic opening 3.

[0035] To balance the deformation of the first elastic port 3 and the second elastic port 5 under force, and to prevent one elastic port from deforming too much and causing damage to the conductor, while the other elastic port only undergoes slight deformation, the connection between the first side 51 and the second side 52 is located in the middle of the first elastic port 3, with the self-locking interface facing the fixing component.

[0036] To improve the adaptability of the conductor to power lines of different diameters, a limiting post is provided on the side of the fixing plate facing the card interface. The limiting post extends into the card interface and clamps the power line together with the first contact surface 1 and the second contact surface 2. By pre-setting limiting posts of different lengths, or by cutting the length of the limiting posts according to actual use, the end of the limiting post away from the fixing plate can clamp the power line together with the first contact surface 1 and the second contact surface 2.

[0037] In this invention, the specific connection method between the conductor and the circuit board is not limited. Whether it is a horizontal connection, a vertical connection, or a connection at any other angle, as long as the electrical connection between the conductor and the circuit board can be satisfied and the card interface and the fixing component can be enclosed to form a clamping space, it is acceptable.

[0038] The fastener can be a cover plate in the circuit board mounting space or a connector that snaps into the conductor, as long as it can press the power cord tightly into the interface.

[0039] More specifically, a snap-fit ​​interface is provided on one side of the conductor, and the other side of the conductor is electrically connected to the circuit board. The fastener snaps into the side wall of the circuit board mounting space from the side away from the circuit board toward the circuit board. In this way, while clamping and fixing the power cord, the fastener can apply a force toward the circuit board to the conductor, thereby improving the connection reliability between the conductor and the circuit board.

[0040] Example 2:

[0041] like Figure 2 As shown, this embodiment is an improved embodiment based on embodiment one. In this embodiment, the terminal block is provided with a cutting edge 6 on both the first contact surface 1 and the second contact surface 2. The cutting edge 6 is used to cut the insulation layer outside the power cord, so that without removing the insulation layer, the cutting edge 6 penetrates the insulation layer and directly contacts the conductor to form an electrical connection. This can prevent the conductor part of the power cord from being exposed to the external environment and causing oxidation, and can extend the service life of the power cord.

[0042] Example 3:

[0043] like Figure 2 As shown, this embodiment is an improved embodiment based on embodiment one. In this embodiment, the terminal block has a third contact surface 4 on the side of the conductor away from the fixing member. The third contact surface 4 is connected to the circuit board. The third contact surface 4 can form a planar contact with the circuit board, which improves the connection firmness of the conductor on the circuit board and can increase the contact area between the conductor and the circuit board, thereby increasing the maximum transmission current between the conductor and the circuit board.

[0044] Furthermore, the third contact surface 4 has two solder feet 7 on the side facing the circuit board; the solder feet 7 can penetrate the reserved holes on the circuit board, thereby allowing dip soldering on the side of the circuit board away from the conductor.

[0045] The size of the solder foot 7 decreases from the third contact surface 4 towards the circuit board. It can be used for dip soldering, or the solder foot 7 can be bent after installation to fix the conductor to the circuit board and increase the connection strength between the conductor and the circuit board.

[0046] Example 4:

[0047] like Figure 3As shown, this embodiment is an improved embodiment based on embodiment three. In this embodiment, the third contact surface 4 of the terminal block gradually decreases in width from the conductor to the welding width. A solder foot 7 is provided on the side of the third contact surface 4 facing the circuit board. The solder foot 7 has a rectangular structure.

[0048] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model.
