Description

Technical Field

[0001] This utility model belongs to the field of connection terminal technology. Specifically, it relates to a quick-connect terminal. Background Technology

[0002] Terminal blocks are accessories used to achieve electrical connections. They are widely used in household circuits, electronic equipment, and industrial automation. Their main function is to provide stable electrical connections, facilitate installation and disassembly, and adapt to different electrical transmission requirements.

[0003] In the market for quick-connect terminals, most rely on spring contact structures. However, these are often insufficient for high-current applications. Higher currents require thicker wires for conduction. Existing terminal technologies, which use spring contact structures, present risks of unstable connections between the wires and terminals, leading to circuit breaks during current transmission. Utility Model Content

[0004] The purpose of this invention is to provide a quick-connect terminal to address the aforementioned shortcomings, solving problems such as unstable connection between the wire and the terminal and the risk of open circuit during current transmission inherent in existing terminals implemented using a spring-loaded structure. To achieve this objective, this invention provides the following technical solution:

[0005] A quick-connect terminal includes a main body, a clamping assembly, a driving assembly, and a reset assembly. The main body has a connection port on one side for inserting a wire. A connection terminal is located above the connection port. The side of the connection terminal that contacts the wire has several protruding structures. The clamping assembly includes a driving plate, a connecting plate, and a lower clamping plate, which are connected via the connecting plate. The lower clamping plate is positioned opposite the connection terminal. The driving assembly drives the driving plate to move the lower clamping plate downwards. After the driving force of the driving assembly is removed, the reset assembly moves the lower clamping plate upwards and clamps the wire between the connection terminal and the lower clamping plate.

[0006] Furthermore, the side of the lower clamp that contacts the wire is configured with a sharp edge structure.

[0007] Furthermore, the reset component is a spring; the upper end of the spring is fixedly connected to the drive plate, and the lower end is fixedly connected to the connecting terminal.

[0008] Furthermore, the driving component is a handle; the handle is rotatably connected to the upper end of the main body; the handle includes a rotating arm and a pressing part; rotating the rotating arm causes the pressing part to press the driving plate downward.

[0009] Furthermore, the middle part of the handle is connected to the upper end of the main body via a pivot.

[0010] Furthermore, the side of the handle that contacts the drive plate is configured with an arc-shaped structure.

[0011] Furthermore, the rotating arm is configured as a telescopic structure and can be housed within the extrusion section.

[0012] Furthermore, a "7"-shaped movable opening is provided on the top of the main body to provide space for the handle to move.

[0013] Furthermore, two springs are provided to provide sufficient restoring force to the lower clamping plate and clamp the wire.

[0014] Furthermore, the spring and the connecting terminal are isolated by an insulating material; the lower clamp and the handle are both made of insulating material.

[0015] The beneficial effects of this utility model are:

[0016] This invention uses a handle and spring structure to clamp the wire, making it easy to operate. Simply turn the handle to clamp the wire, allowing for quick wire connection. The connection terminal has several protruding structures, and the lower clamp plate has sharp edges. When the spring force is constant, the contact area is reduced, thereby increasing the pressure and making the wire easier to deform, ensuring a more secure wire connection.

[0027] Example:

[0028] See attached Figures 1-7This embodiment provides a quick-connect terminal, including a main body 1, a clamping assembly, a driving assembly, and a reset assembly. A connection port 2 is provided on one side of the main body 1, and a connection terminal 4 is located above the connection port 2. A wire 3 is inserted into the connection port 2 and contacts the connection terminal 4 to achieve transmission. The clamping assembly includes a driving plate 6 and a lower clamping plate 7, which are connected by a connecting plate. The driving plate 6 is fixedly connected to the upper side of the connection port 2 through the reset assembly. One end of the connecting plate is connected to the side of the driving plate 6, and the other end is connected to the side of the lower clamping plate 7. The driving plate 6 and the lower clamping plate 7 are arranged opposite to each other, and the lower clamping plate 7 is located inside the connection port 2. The connecting plate is located on the side of the driving plate 6 and the lower clamping plate 7 to avoid interference with the insertion of the wire 3 into the connection port 2. The drive assembly moves the drive plate 6 downwards, and the drive plate 6 simultaneously moves the reset assembly and the lower clamping plate 7 downwards. At this time, the lower clamping plate 7 is located below the connection port 2. The wire 3 is inserted into the connection port 2. The driving force of the drive assembly is removed, and the reset assembly moves the drive plate 6 upwards to reset. The lower clamping plate 7 moves upwards synchronously. The force of the reset assembly clamps the wire 3 between the lower clamping plate 7 and the connection terminal 4.

[0029] In this embodiment, the reset component is preferably a spring 9 structure. Two springs 9 with appropriate elastic force are selected, both located at the upper end of the upper side of the connection port 2. The upper side of the connection port 2 is connected and fixed to the main body 1. The upper side of the spring 9 is fixedly connected to the drive plate 6. The drive plate 6 receives the downward squeezing force from the drive component. During this process, the spring 9 continuously compresses and stores a certain amount of elastic potential energy. At this time, the lower clamping plate 7 also gradually moves to the lower side of the connection port 2. When the width between the lower clamping plate 7 and the connection terminal 4 on the upper side of the connection port 2 is greater than the diameter of the wire 3, the drive component stops applying the downward force. At this time, the wire 3 is inserted into the connection port 2, the force of the drive component is withdrawn, and the spring 9 gradually begins to recover upward. During the recovery process, the lower clamping plate 7 is blocked by the wire 3. That is, the connection terminal 4 and the lower clamping plate 7 rely on the spring force to transform into a clamping force for clamping the wire 3. Furthermore, several protrusions 5 are provided on the connecting terminal 4 that contacts the upper side of the wire 3, reducing the contact area between the wire 3 and the connecting terminal 4. Under the condition of a constant spring force, the reduced contact area increases the pressure, making the wire 3 easier to deform and thus making the connection with the connecting terminal 4 more secure. An upward-facing sharp edge 8 is provided on the lower clamping plate 7 that contacts the lower side of the wire 3. This also utilizes the principle of increasing pressure by reducing the contact area to ensure a secure connection between the lower clamping plate 7 and the wire 3. The sharp edge 8 must be designed to prevent cutting damage to the wire 3 under the action of the spring force. This invention improves the stability of the connection between the wire 3 and the connecting terminal 4 by increasing the spring force and increasing the pressure on the contact surface with the wire 3, thus preventing it from loosening.

[0030] In this embodiment, the driving component is specifically a handle 10, which is rotatably connected to the upper part of the main body 1 via a pivot in the middle. A rotating arm and a pressing part are located on either side of the middle of the handle 10. By rotating the rotating arm on the handle 10, the pressing part on the handle 10 gradually contacts the driving plate 6 and presses the driving plate 6 downwards, as shown in the attached diagram. Figure 3 As shown, the main body 1 has a "7"-shaped movable opening, providing space for the handle 10 to rotate and apply... Figure 3 The force indicated by the arrow, when the rotating arm rotates to angle A > 0°, causes the handle 10 to be restricted by the reaction force of the spring 9 and the "7"-shaped movable opening on the main body 1, preventing it from continuing to rotate in the original direction and locking the handle 10. At this time, there is space between the lower clamp 7 inside the connection port 2 and the connection terminal 4 for the insertion of the wire 3. When it is necessary to unlock the handle 10, an opposite rotational force is applied, as shown in the attached diagram. Figure 4 The force indicated by the arrow means that the handle 10 is in a free state under the spring force, thus completing the unlocking process. The side of the extrusion part that contacts the drive plate 6 is designed with an arc shape, which can reduce the resistance between the extrusion part and the drive plate 6, making it easier for the operator to drive the extrusion part to extrude the drive plate 6 by rotating the rotating arm.

[0031] In this embodiment, the extrusion part is preferably configured as an internal hollow structure and a slide rail structure is provided to slide the rotating arm inside the extrusion part. When it is needed to work, the rotating arm extends out of the extrusion part. A corresponding limiting structure is provided to prevent the rotating arm from detaching from the extrusion part. When the handle 10 is not needed to work, its space occupation is further reduced, which facilitates transportation and other operations.

[0032] In this embodiment, the spring 9 is a conductive structure, and an insulating material is further provided between the spring 9 and the connecting terminal 4 for insulation, while ensuring the safety of the operator. The handle 10, the lower clamping plate 7, the connecting plate, and the drive plate 6 are also made of insulating material.

[0033] In practical use, the connection terminal 4 of this utility model can be set with multiple connection terminals 4 and integrated into one to form multiple connection ports 2, so as to quickly connect multiple wires 3. The number of connection terminals 4 can be set according to the specific scenario.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
