[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model discloses a contact spring for a printer. The circuit is fixed via a connecting part, and then the spring body is inserted into a fixed mounting base and fixed to the mounting base via mounting holes and protrusions.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Specific implementation examples are given below.

[0023] like Figures 1 to 3 As shown, an embodiment of the present invention provides a contact spring for a printer, comprising a spring body 1; an abutment surface 2 at one end of the spring body 1; an installation hole 3 inside the spring body 1; a connecting part 4 at one end of the spring body 1; the connecting part 4 being located at one end of the spring body 1 away from the abutment surface 2; the installation hole 3 being located on the side of the spring body 1 away from the abutment surface 2; and contact protrusions 5 on the surface of the spring body 1. During operation, when it is necessary to connect the printer's wiring, the wire harness to be connected can be brought into contact with the spring body 1 and fixed by the connecting part 4. Then, the spring body 1 is inserted into a fixed mounting base and fixed to the protrusions on the mounting base through the installation hole 3, thus fixing the spring body 1 to the mounting base. The mounting base is then installed on the printer, so that the contact protrusions 5 on the spring body 1 contact the contacts on the circuit board, thereby connecting the printer's wiring and making the connection of the printer wiring more convenient.

[0024] The spring body 1 is provided with a bending part 6; the bending part 6 is located at the position of the corresponding contact protrusion 5; during operation, by providing the bending part 6 on the spring body 1, the spring body 1 can have a certain elasticity, and then the elasticity of the spring body 1 can press the contact protrusion 5 against the contact point, thereby achieving stable contact between the contact protrusion 5 and the contact point on the circuit board, resulting in a better connection effect of the circuit.

[0025] The spring body 1 is provided with a bending step 7; the bending step 7 is located between the corresponding mounting hole 3 and the bending part 6; during operation, the design of the bending step 7 on the spring body 1 can ensure the elasticity of the bending part 6 on the spring body 1, and can disperse the deformation when the spring body 1 is compressed too much, ensuring that the contact protrusion 5 at the bending part 6 on the bending part 6 of the spring body 1 makes smooth contact with the contact point on the circuit board, ensuring the continuity of the circuit, reducing the unstable factors of the equipment, and allowing the machine to operate efficiently.

[0026] The surface of the spring body 1 is provided with a gold plating layer 8; the gold plating layer 8 is set at the position of the corresponding contact bump 5; during operation, since gold has the property of not being easily oxidized, by plating a gold plating layer 8 on the spring body 1, the spring body 1 and the contact bump 5 can maintain a stable low contact resistance for a long time, thereby increasing the conductivity stability of the spring body 1.

[0027] The side of the spring body 1 is provided with an anti-deformation groove 9; the anti-deformation groove 9 is located on the side of the spring body 1 corresponding to the mounting hole 3; during operation, since the spring body 1 is punched, if a straight blade is used for punching, the spring body 1 is prone to deformation during punching. By setting the blade to adapt to the shape of the anti-deformation groove 9, the contact area between the blade and the spring body 1 during punching can be increased, thereby effectively preventing the spring body 1 from deforming during punching.

[0028] Multiple anti-slip protrusions 10 are fixedly attached to the side wall of the connecting part 4; the anti-slip protrusions 10 are provided on the side wall of the connecting part 4 near the spring body 1; during operation, when the wire harness is fixed by the connecting part 4, the anti-slip protrusions 10 on the side wall of the connecting part 4 can make the contact area between the connecting part 4 and the wire harness larger, thereby making the connection part 4 more stable when fixing the wire harness.

[0029] The spring body 1 is made of copper-zinc alloy. During operation, the copper-zinc alloy has good machinability and is suitable for processes such as stamping, turning, and casting, which makes the production of the spring body 1 more convenient. At the same time, the addition of zinc improves the hardness and deformation resistance of copper, making it more resistant to mechanical wear than pure copper, which can increase the service life of the spring body 1.

[0030] When it is necessary to connect the printer's wiring during operation, the wire harness to be connected can be brought into contact with the spring body 1 and fixed by the connecting part 4. Then, the spring body 1 is inserted into the fixed mounting base and fixed by the mounting hole 3 and the protrusion on the mounting base, thus fixing the spring body 1 on the mounting base. After that, the mounting base is installed on the printer, so that the contact protrusion 5 on the spring body 1 makes contact with the contact point on the circuit board, thus conducting the printer's wiring, making the connection of the printer wiring more convenient.

[0031] By providing a bending portion 6 on the spring body 1, the spring body 1 can have a certain elasticity. In turn, the elasticity of the spring body 1 can push the contact protrusion 5 against the contact point, thereby achieving stable contact between the contact protrusion 5 and the contact point on the circuit board, resulting in a better connection effect of the circuit.

[0032] The design of the bending step 7 on the spring body 1 can ensure the elasticity of the bending part 6 on the spring body 1. When the spring body 1 is compressed too much, it can disperse the deformation, ensuring that the contact protrusion 5 at the bending part 6 on the bending part of the spring body 1 makes smooth contact with the contact point on the circuit board, ensuring the continuity of the circuit, reducing the unstable factors of the equipment, and making the machine operate efficiently.

[0033] Because gold is not easily oxidized, by plating a gold layer 8 on the spring body 1, the spring body 1 and the contact bump 5 can maintain a stable low contact resistance for a long time, thereby increasing the conductivity stability of the spring body 1.

[0034] Since the spring body 1 is punched, if a straight blade is used for punching, the spring body 1 is prone to deformation during the punching process. By setting the blade to adapt to the shape of the anti-deformation groove 9, the contact area between the blade and the spring body 1 during punching can be increased, thereby effectively preventing the spring body 1 from deforming during punching.

[0035] When the wire harness is fixed by the connecting part 4, the anti-slip protrusions 10 provided on the side wall of the connecting part 4 can increase the contact area between the connecting part 4 and the wire harness, thereby making the connection part 4 more stable when fixing the wire harness.

[0036] Because copper-zinc alloy has good machinability, it is suitable for processes such as stamping, turning, and casting, which makes the production of the spring body 1 more convenient. At the same time, the addition of zinc improves the hardness and deformation resistance of copper, making it more resistant to mechanical wear than pure copper, thus increasing the service life of the spring body 1.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
