Description

Technical Field

[0001] The utility model relates to strip steel production equipment, in particular to a power connection terminal and a clamping mechanism for clamping the power connection terminal. Background Art

[0002] Figure 1 and Figure 2 The figure shows a power converter, which includes a housing 1, a circuit board 2 with a control circuit, a conductive pin 3, and a conductive terminal 4. The circuit board 2 is installed in the cavity of the housing 1, the conductive terminal 4 is fixed on the circuit board 2, and one end of the conductive pin 3 passes through the housing 1 and is plugged into the conductive terminal 4.

[0003] The conductive terminal 4 includes a main body 4a, a jumper 4b, a plug pin 4c, and a clamping member 4d. There are multiple main bodies 4a. The two ends of the jumper 4b are connected to one end of each of the main bodies 4a, forming a guide cavity 4e between the jumper 4b and the main bodies 4a. The clamping member 4c is fixed to the main body 4a. The other end of the main body 4a is connected to the plug pin 4c, which passes through the circuit board 2 and is secured to the circuit board 2 by welding. The clamping member 4d is fixed to the main body 4a. The conductive pin 3 passes through the guide cavity 4e and mates with the clamping member 4c, which clamps the conductive pin 3.

[0004] When assembling the conductive terminal 4 with the circuit board 2, a plug hole is provided on the circuit board 2. The main part 4a is clamped by a clamping mechanism so that the plug pin 4c passes through the plug hole on the circuit board 2, and then the plug pin 4c is fixed to the circuit board 2 by soldering.

[0005] When the conductive terminal 4 is assembled with the circuit board 2 using a clamping mechanism, the conductive terminal 4 will be deformed after being subjected to the clamping force of the clamping mechanism. Since the conductive terminal 4 is made of carbon steel, the elasticity of carbon steel is slightly worse than that of manganese steel, and the conductive terminal 4 has a low deformation recovery rate. The surface of the conductive terminal 4 is smooth. If the clamping force of the clamping mechanism does not change, the conductive terminal 4 will fall off the clamping mechanism, making it impossible to assemble the conductive terminal 4 with the circuit board 2. Utility Model Content

[0006] The utility model provides a power connection terminal and a clamping mechanism for clamping the power connection terminal. When the power connection terminal of the utility model is plugged into a circuit board, the power connection terminal and the clamping mechanism can be prevented from being separated.

[0007] The technical solutions to the above technical problems are as follows:

[0008] The power connection terminal includes a main body component, a jumper component, a plug pin, and a clamping component. There are multiple main body components. After the two ends of the jumper component are respectively connected to one end of these main body components, a guide cavity is formed between the jumper component and these main body components. The clamping component is fixed to the main body component, and the other end of the main body component is connected to the plug pin. The clamping component is provided with a friction-increasing component for cooperating with the clamping mechanism to increase friction.

[0009] The clamping mechanism for clamping the power connection terminal includes a clamping driver and a clamping arm. The power output end of the clamping driver is connected to the clamping arm. The clamping arm is provided with a blocking portion. A groove for cooperating with the power connection terminal is formed between the blocking portion and the clamping arm.

[0010] In the present invention, after the friction-increasing component is provided on the main component, when the clamping mechanism clamps the power connection terminal, the friction and elastic force between the power connection terminal and the clamping mechanism are increased by the friction-increasing component, so that the power connection terminal will not be separated from the clamping mechanism, thereby ensuring the reliability of the power connection terminal when being plugged into the circuit board.

[0020] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

[0021] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0023] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediate medium; internal communication between two components, or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0024] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0025] like Figure 3As shown, the power connection terminal of the present invention includes a main body component 4a, a jumper component 4b, a plug pin 4c, and a clamping component 4d. The main body components 4a are two, and the two main body components 4a are arranged in an eight-shaped shape. After the two ends of the jumper component 4b are connected to one end of the main body components 4a, a guide cavity 4e is formed between the jumper component 4b and the main body components 4a. The clamping component 4c is fixed to the main body component 4a, and the other end of the main body component 4a is connected to the plug pin 4c. The clamping component 4d is provided with a friction-increasing component for cooperating with the clamping mechanism to increase friction. The friction-increasing component is composed of a plurality of tooth-shaped components 4f, which are spaced apart along the height direction of the main body component 4a. The side surfaces of the tooth-shaped components 4f are trapezoidal, for example, right-angled trapezoidal and isosceles trapezoidal, and the right-angled trapezoidal tooth components 4f and the isosceles trapezoidal tooth components 4f are arranged alternately. There is an angle between each tooth-shaped part 4f and the main part 4a, that is, the tooth-shaped part 4f is arranged obliquely relative to the main part 4a, so that the power connection terminal has better elasticity as a whole, and when the power connection terminal is clamped by the clamping mechanism, its deformation will be smaller.

[0026] The plug-in pin 4c includes a connecting section 4c1 and a plug-in section 4c2. One end of the connecting section 4c1 is fixed to the main body part 4a, and the other end of the connecting section 4c1 is fixed to the plug-in section 4c2. The plug-in section 4c2 is arc-shaped or wavy. In this embodiment, the plug-in section 4c2 is preferably arc-shaped. When the plug-in section 4c2 passes through the through hole on the circuit board 2, the arc-shaped part of the plug-in section 4c2 is blocked by the circuit board 2. Obviously, if the plug-in pin 4c of the present invention is pulled out from the circuit board 2, the pulling force required by the present invention is much greater than that of the plug-in pins that are all straight segments. Therefore, after the plug-in pin 4c of the present invention is fixed to the circuit board 2 by welding (tin soldering), the stability of the entire power connection terminal is better.

[0027] The clamping member 4d is provided with a raised portion 4h for increasing its strength. Two clamping members 4d are arranged in a figure-eight shape. The raised portions 4h are located on opposing inner walls of the two clamping members 4d. A pressing force is applied from the outer wall of the clamping member 4d to the inner wall, forming a depression on the outer wall of the clamping member 4d and a raised portion 4h on the inner wall of the clamping member 4d. The raised portions 4h not only increase the strength of the clamping member 4d but also enhance the clamping force.

[0028] In the present utility model, Figure 4 As shown, the friction-increasing component can also be composed of a plurality of strip components 4g, wherein a single strip component 4g extends along the height direction of the main component 4a, and the plurality of strip components 4g are arranged at intervals along the width direction of the main component 4a.

[0029] like Figures 5 and 6 , a clamping mechanism for clamping the above-mentioned power connection terminal, the clamping mechanism includes a clamping driver 11 and a clamping arm 12, the power output end of the clamping driver 11 is connected to the clamping arm 12, and the clamping arm 12 is provided with a blocking portion 14, and a groove 15 for cooperating with the power connection terminal is formed between the blocking portion 14 and the clamping arm 12. After the power connection terminal enters the groove 15, the blocking portion 14 cooperates with the friction-increasing component, that is, the tooth-shaped friction-increasing component will be blocked by the blocking portion 14.

[0030] In this embodiment, the clamping actuator 11 preferably employs a finger cylinder. Two clamping arms 12 are provided, each consisting of a connecting portion 12a, a transition portion 12b, and a clamping portion 12c. One end of the connecting portion 12a is connected to the output end of the finger cylinder, the other end of the connecting portion 12a is connected to one end of the transition portion 12b, and the other end of the transition portion 12b is connected to the clamping portion 12c. The transition portion 12b is L-shaped, and the blocking portion 14 is disposed on the clamping portion 12c. Both clamping portions 12c have inclined surfaces that mate with the main portion 4a and the friction-increasing component.

[0031] The clamping mechanism also includes a push rod 13 for limiting the power connection terminal from sliding in the direction opposite to the insertion direction during insertion into the circuit board 2. Push rod 13 is fixed to the clamping driver 11. Push rod 13 includes a mounting portion 13a, a bent portion 13b, and a rod-shaped member 13c. The mounting portion 13a is fixed to the clamping driver 11 and is also fixed to one end of the bent portion 13b. The other end of the bent portion 13b is fixed to the rod-shaped member 13c. The other end of the rod-shaped member 13c is a free end for abutting against the bridge member 4b.

[0032] The clamping mechanism in the present invention is connected to the driving device, which can be a robot. The robot drives the clamping mechanism to perform lifting and translational movements. When the robot drives the clamping mechanism to pick up materials from the vibrating loader, after the clamping mechanism descends, the other end of the rod-shaped component 13c forms abutment with the cross-connection component 4b, and the clamping arm 12 clamps the main body component 4a and the friction-increasing component. The robot drives the clamping mechanism to rise and move to the top of the circuit board 2. The robot drives the clamping mechanism to descend, so that the plug-in pin 4c passes through the through hole on the circuit board 2. When the plug-in pin 4c passes through the through hole on the circuit board 2, since the other end of the rod-shaped component 13c abuts against the cross-connection component 4b, it will not cause the power connection terminal to slide in the groove 15 in the opposite direction of insertion.

[0033] The above disclosure is only a preferred embodiment of the present application, and certainly cannot be used to limit the scope of rights of the present utility model. Ordinary technicians in this field can understand that implementing all or part of the structure of the above embodiment and making equivalent changes in accordance with the claims of this application still fall within the scope covered by the application.
