Description

Technical Field

[0001] This invention relates to the field of connection structure technology, and in particular to a vibration-damping wire terminal assembly. Background Technology

[0002] Electrical cabinets often contain high-current control and protection devices, such as circuit breakers, AC contactors, and surge protectors. These devices are typically connected to wires via metal wire clamps, which are used to introduce current into the device.

[0003] However, when using the above connection method, if a component is damaged and needs to be replaced, the wire clamp should be loosened first, and then the wire should be pulled out; after replacing the component, the wire should be inserted again; finally, the wire clamp should be tightened. Therefore, it is clear that the conventional connection method cannot allow for quick replacement of components within the equipment, and when a component is damaged, it has a significant impact on the production process.

[0004] In industrial equipment, if spring terminals are used directly for electrical connection, the relative vibration between the wire and the equipment will be transmitted to the spring terminal and the insert, causing relative vibration between the spring terminal and the insert. This directly affects the connection stability between the spring terminal and the insert, resulting in poor contact between the spring terminal and the insert and affecting the electrical life of the component. Summary of the Invention

[0005] The purpose of this invention is to provide a vibration-damping wire terminal assembly to solve the problems existing in the prior art, enabling rapid replacement of components within the equipment and ensuring good connection stability.

[0006] To achieve the above objectives, the present invention provides the following solution: This invention provides a vibration-damping wire terminal assembly, including a crimping element, a connecting element, an internal wire, and a plug-in connector. A first end of the internal wire is fixedly connected to the connecting element and electrically connected to it. The crimping element is used to press the connecting element against an external wire. A second end of the internal wire is fixedly connected to the plug-in connector and electrically connected to it. The plug-in connector is detachably connected to a plug-in mating part of an external device, and the connection between the plug-in connector and the plug-in mating part of the external device enables circuit conduction.

[0007] Preferably, the first end of the internal wire is fixedly connected to the connecting element by an ultrasonic welding process.

[0008] Preferably, the wire clamping element is a wire clamping frame, which can clamp the connecting element and the external wire.

[0009] Preferably, the wire clamping frame includes a frame and a bolt. The upper end of the frame is provided with a threaded hole. The connecting element and the external wire both extend into the frame. The bolt can be threaded into the threaded hole, and the lower end of the bolt is used to contact the connecting element and press the connecting element against the external wire.

[0010] Preferably, the pressure frame is made of metal.

[0011] Preferably, the internal conductor is a flexible conductor.

[0012] Preferably, the plug-in connector is a spring-loaded terminal, the plug-in mating part is a insert, and the spring-loaded terminal and the insert can be plugged into each other.

[0013] Preferably, the second end of the internal wire is fixedly connected to the plug-in connector by a crimping process.

[0014] Preferably, the connecting element is a connecting piece, one end of which is fixedly connected to the internal wire, and the other end of which extends into the wire pressing element.

[0015] Preferably, the connecting piece is a copper sheet.

[0016] The present invention achieves the following technical effects compared to the prior art: The vibration-damping wire terminal assembly provided by this invention includes a crimping element, a connecting element, an internal wire, and a plug-in connector. The first end of the internal wire is fixedly connected to the connecting element and is electrically connected to the connecting element. The crimping element is used to press the connecting element and the external wire together, ensuring a tight connection and enabling conductivity through the connecting element. The second end of the internal wire is fixedly connected to the plug-in connector and is electrically connected to the plug-in connector. The plug-in connector allows for detachable connection to a plug-in mating part of an external device. When the external device is damaged and needs replacement, the connection between the plug-in connector and the plug-in mating part can be directly disconnected for replacement. Simply replace the external component and connect its plug-in mating part to the plug-in connector. The operation is simple and convenient. After the plug-in connector is connected to the plug-in mating part of the external component, the circuit is made conductive. At the same time, the above connection method ensures that there is no relative movement between the crimping element, the connecting element, and the plug-in mating part. When the equipment vibrates, the crimping element, the connecting element, and the plug-in mating part vibrate at the same frequency inside the equipment. There is no obvious relative movement between the plug-in connector and the plug-in mating part. Moreover, the vibration of the external component is transmitted to the crimping element through the external wire, and thus cannot be transmitted to the plug-in connector and the plug-in mating part through the internal wire, thereby improving the connection stability.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] The purpose of this invention is to provide a vibration-damping wire terminal assembly to solve the problems existing in the prior art, enabling rapid replacement of components inside the equipment, and providing good connection stability.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-2As shown, this embodiment provides a vibration-damping wire terminal assembly, including a crimping element 1, a connecting element 5, an internal wire 3, and a plug-in connector 4. The first end of the internal wire 3 is fixedly connected to the connecting element 5 and electrically connected to it. The crimping element 1 is used to press the connecting element 5 and the external wire together, ensuring a tight connection and enabling conductivity through the connecting element 5. The second end of the internal wire 3 is fixedly connected to the plug-in connector 4 and electrically connected to it. The plug-in connector 4 allows for detachable connection to the plug-in mating parts of external devices. When an external device is damaged and needs replacement, the plug-in connector 4 can be directly disconnected from the plug-in mating parts. The connection is simple and convenient. Simply replace the external device with a new one and connect its plug-in mating part to the plug-in connector 4. After the plug-in connector 4 is connected to the plug-in mating part of the external device, the circuit is made conductive. At the same time, the above connection method ensures that there is no relative movement between the crimping element 1, the connecting element 5 and the plug-in mating part. When the equipment vibrates, the crimping element 1, the connecting element 5 and the plug-in mating part vibrate at the same frequency inside the equipment. There is no obvious relative movement between the plug-in connector 4 and the plug-in mating part. Moreover, the vibration of the external device is transmitted to the crimping element 1 through the external wire, and then it can no longer be transmitted to the plug-in connector 4 and the plug-in mating part through the internal wire 3, thus improving the connection stability.

[0023] Specifically, the first end of the internal wire 3 is fixedly connected to the connecting element 5 through ultrasonic welding, thereby ensuring a stable electrical connection between the internal wire 3 and other external devices and preventing relative movement between the first end of the internal wire 3 and the connecting element 5.

[0024] The wire clamping element 1 is a wire clamping frame, which can clamp the connecting element 5 and the external wire to achieve a tight connection between the connecting element 5 and the external wire, thereby enabling conductivity. At the same time, the wire clamping frame makes the electrical connection between the plug-in mating part and the external device form a whole without relative vibration. Then, by clamping the plug-in connector 4 to the second end of the internal wire 3, a component structure that can be quickly plugged in and out is formed. Thus, when replacing the device, the operation is limited to the functional connection end and does not touch the vibration-damping fixed end. The traditional full-link disassembly and assembly is simplified to partial plugging and unplugging, making the operation simple and convenient.

[0025] The wire clamping frame includes a frame and bolts 2. The upper end of the frame has a threaded hole, through which the connecting element 5 and the external wire extend. Bolts 2 can be threaded into the threaded hole to connect to the frame. The lower end of bolts 2 is used to contact the connecting element 5 and press the connecting element 5 against the external wire, achieving close contact between the connecting element 5 and the external wire. By tightening bolts 2, the distance between the lower end of bolts 2 and the bottom surface of the frame can be increased or decreased, thus facilitating the tightening and loosening of the connecting element 5 and the external wire. It also has a wide range of applications.

[0026] As a preferred embodiment, the wire clamp is made of metal, which enables rigid fixation of the connecting element 5 and the external wire.

[0027] In this embodiment, the specific structure of the wire pressing element 1 is not limited to the wire pressing frame, but can also adopt a structure that can achieve rigid vibration prevention and fixation, such as a snap-fit.

[0028] As a preferred embodiment, the internal conductor 3 is a flexible conductor.

[0029] The plug-in connector 4 is a spring-loaded terminal, and the mating part is a insert. The spring-loaded terminal and the insert can be plugged in and can achieve elastic plugging and unplugging, making it easy to install and remove, with good connection stability and enabling quick docking. At the same time, the elastic self-locking structure of the spring-loaded terminal enables tool-less operation. No matter how narrow the installation space, as long as the device is within finger reach, plugging and unplugging can be completed, greatly reducing the requirements for the operating environment. Furthermore, since the end with the wire clamp remains stationary, new devices can be used immediately after insertion, eliminating the risk of reinstallation and debugging.

[0030] In this embodiment, the connecting element 5 is fixed to the product, and the insert is also fixed to the product. The wire clamping frame presses the connecting element 5 and the external wire together. The wire clamping frame, connecting element 5, and insert do not move relative to each other. When the equipment vibrates, the above three components vibrate at the same frequency inside the equipment, and there is no obvious relative movement between the spring terminal and the insert. The vibration of the external device is transmitted to the wire clamping frame through the external wire, and therefore cannot be transmitted to the mating point of the spring terminal and the insert through the internal wire 3.

[0031] The second end of the internal wire 3 is fixedly connected to the plug-in connector 4 through a crimping process.

[0032] The connecting element 5 is a connecting piece. One end of the connecting piece is fixedly connected to the internal wire 3, and the other end of the connecting piece extends into the wire pressing element 1, which facilitates the pressing of the external wire. However, in this embodiment, the specific structure of the connecting element 5 is not limited to a sheet shape. Block-shaped, column-shaped and other conductive components used for transition connection can also be used. However, the sheet shape can achieve a better pressing effect.

[0033] In this embodiment, the connecting piece is designed as an L-shaped bending structure. One end is ultrasonically welded to the external wire, and the other end is pressed tightly against the wire clamping frame, which can adapt to the compact installation space inside the electrical cabinet and reduce the space occupied by the components.

[0034] As a preferred embodiment, the connecting piece is a copper sheet.

[0035] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
