Description

Technical Field

[0001] This utility model relates to the field of power metering equipment technology, specifically to a smart terminal button box. Background Technology

[0002] In the manufacturing and use of smart terminal devices, the terminal box is a key component that connects internal circuitry to external cables, and the reliability of its connection and the ease of operation are of paramount importance.

[0003] Traditional terminal boxes, especially those used to secure multiple wires, are generally cumbersome and inefficient. They typically require the use of screwdrivers to tighten each wire individually. When inspecting, replacing, or adjusting a wire, the same process of loosening the corresponding screws is necessary to remove it. This process is also tedious and increases the risk of misoperation or omission. Secured and released wires are two separate, often tool-assisted, steps that cannot be completed in a single, continuous motion. This impacts maintenance and installation efficiency. Therefore, we propose a smart terminal junction box. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a smart terminal button box to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A smart terminal's terminal box includes a terminal and a terminal block disposed at the bottom of the terminal. The terminal block has a cavity extending along its axial direction. The cavity has an opening facing the operation side. A rotating unit that can rotate about an axis in both directions is provided at the opening. When the rotating unit rotates in the forward direction, it closes the opening and drives an abutment unit to press down to fix a wire placed on the bottom wall of the cavity. When the rotating unit rotates in the reverse direction, it opens the opening and drives the abutment unit to lift up to release the fixation of the wire and allow the wire to be pulled out.

[0007] Preferably, the rotating unit includes a rotating shaft, a horizontal plate, an arc plate, and a contact plate; the rotating shaft is located near the opening of the chamber; one end of the arc plate is connected to the rotating shaft and can rotate around it in both directions; the horizontal plate is connected to the other end of the arc plate; and the contact plate is connected to the end of the arc plate away from the horizontal plate.

[0008] Preferably, it also includes an abutment unit; the abutment unit includes a bent plate, an extension plate, and a working plate; one end of the bent plate is pivotally connected to the terminal block away from the opening of the chamber, and the other end extends to the top of the bottom wall of the chamber; the extension plate is connected to the end of the bent plate near the bottom wall of the chamber and extends into the chamber; the working plate is connected to the extension plate and extends upward to below the contact plate; a pressure plate is connected to the horizontal plate; when the rotating unit rotates in the forward direction to close, the pressure plate presses against the bent plate to press down the entire abutment unit to fix the wire; when the rotating unit rotates in the reverse direction to open, the contact plate pushes the working plate upward to lift the entire abutment unit to release the wire.

[0009] Preferably, the extension plate extends towards the bottom wall of the chamber to form a pressure plate; when the abutment unit is pressed down, the pressure plate presses the wire tightly against the bottom wall of the chamber; the pressure plate and the bottom wall of the chamber form an angle of 30°-75°.

[0010] Preferably, the extension plate and the pressure plate are provided with wiring grooves for guiding wires; when the abutment unit is pressed down, the wiring grooves cooperate with the bottom wall of the chamber to form a pressing space.

[0011] Preferably, the side of the horizontal plate away from the chamber is connected to a push-pull plate that tilts toward the operating side.

[0012] Preferably, a fixing chamber is provided on the open side wall of the terminal block, and a pair of arc-shaped spring pieces with opposite arc surfaces forming a channel are provided in the fixing chamber; a fixing protrusion is connected to the horizontal plate; when the rotating unit rotates to the closed position, the fixing protrusion is inserted into the channel between the pair of arc-shaped spring pieces and is elastically clamped and fixed.

[0013] This utility model provides a terminal button box for a smart terminal. It has the following beneficial effects:

[0014] 1. By rotating the unit in both directions, the terminal block opening can be closed / opened, and the wire can be clamped / released. When rotating in the forward direction, the pressure plate presses down against the contact unit to fix the wire; when rotating in the reverse direction, the contact plate lifts the working plate, causing the contact unit to tilt up, facilitating the quick removal of the wire. The operation is simple and efficient. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, what is described is only a part of this utility model, not all of it. Based on this utility model, all other inventions obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] See attached document Figure 1-5 A smart terminal's terminal box includes a terminal 1 and multiple terminal blocks 2 disposed at the bottom of the terminal 1;

[0023] The terminal block 2 has a chamber 21 extending along its axial direction. The chamber 21 has an opening facing the operating side. A rotating unit 3 that can rotate in both directions is provided at the opening of the terminal block 2. When the rotating unit 3 rotates in the forward direction, it can close the opening of the terminal block 2. When the rotating unit 3 rotates in the reverse direction, the rotating unit 3 is lifted up and abuts against the side wall of the opening of the terminal block 2.

[0024] The rotating unit 3 includes a rotating shaft 31, a horizontal plate 34, an arc plate 35, and a contact plate 36. The horizontal plate 34, the arc plate 35, and the contact plate 36 are connected in sequence. The rotating shaft 31 is provided at the opening near the chamber 21. The arc plate 35 is connected to the rotating shaft 31 to form a forward and reverse rotation around the shaft.

[0025] It also includes abutting unit 4, which can be held by pressure plate 32 connected to horizontal plate 34, pressing abutting unit 4 against the bottom wall of cavity 21 to fix the wires passing through cavity 21;

[0026] The abutment unit 4 includes a bent plate 41, one end of which is pivotally connected to 21 away from the chamber, and the other end is connected to the bottom wall of the chamber 21 and an extension plate 42. A wiring groove 44 is provided on the bent plate 41 and the extension plate 42. When the wire passes through the chamber 21, the horizontal plate 34 rotates in the forward direction, and the pressure plate 32 abuts against the bent plate 41, which can press the bent plate 41 and the extension plate 42 down simultaneously until they abut against the bottom wall of the chamber 21. After the bent plate 41 is pressed down, the wiring groove 44 and the bottom wall of the chamber 21 cooperate to form a pressing space. The wiring groove 44 is used for the wire inlet, thereby completing the fixation of the wire.

[0027] A working plate 43 extends from the extension plate 42 toward the chamber 21. The working plate 43 is located above the contact plate 36 so that the working plate 43 can be lifted by the contact plate 36. When the horizontal plate 34 rotates in the opposite direction, the contact plate 36 at the end of the arc plate 35 will lift the working plate 43, thereby tilting the bent plate 41 and the extension plate 42 that hold the wire upward, making it easier to pull the wire out.

[0028] The extension plate 42 extends towards the bottom wall of the chamber 21 to form a wire clamping plate 45. When the wire is placed on the bottom wall of the chamber 21, the horizontal plate 34 rotates in the forward direction, and the clamping plate 32 abuts against the bent plate 41, causing the bent plate 41, the extension plate 42 and the wire clamping plate 45 to press down synchronously until the wire clamping plate 45 presses the wire tightly against the bottom wall of the chamber 21, thereby fixing the wire. A wiring groove 44 can be opened on the extension plate 42 and the wire clamping plate 45 to guide the wire. The angle between the wire clamping plate 45 and the bottom wall of the chamber 21 is 30°-75°, which can effectively clamp the wire and is not easy to damage the wire.

[0029] To facilitate the forward and reverse rotation of the horizontal plate 34, a push-pull plate 37 is connected to the side of the horizontal plate 34 away from the chamber 21. The push-pull plate 37 is tilted towards the operating side to facilitate the control of the rotation of the horizontal plate 34.

[0030] A fixing chamber 22 is also provided on the open side wall of the chamber 21. The fixing chamber 22 is provided with a pair of arc-shaped spring pieces 23 with opposite arc surfaces and a channel. A fixing protrusion 33 corresponding to the channel is also connected on the horizontal plate 34. When the horizontal plate 34 is rotated to the closed position, the fixing protrusion 33 is inserted into the channel formed between the pair of arc-shaped spring pieces 23 and is elastically clamped and fixed by the arc-shaped spring pieces 23.

[0032] The above description is only used to illustrate the technical solutions of this utility model, and is not intended to limit it. Although the utility model has been described in detail with reference to the foregoing, those skilled in the art should understand that modifications can still be made to the foregoing technical solutions, or equivalent substitutions can be made to some of the technical features.
