Description
Technical Field
[0001] This utility model relates to the technical field of power unit five-in-one control board, specifically a power system connection device for a power unit five-in-one control board. Background Technology
[0002] The five-in-one power unit control board is an integrated electronic control board. It is mainly used for centralized control and management of power units and is commonly used in power electronic equipment, such as high-voltage frequency converters. In these devices, the power units are the key part for realizing power conversion, and the five-in-one control board is the core component that coordinates and controls the operation of these five power units.
[0003] The aforementioned device lacks a structure for quick clamping and connecting control board wires during use. As a result, most existing control boards still rely on screw washers for clamping when connecting to wire harnesses. While this effectively prevents disconnection, it requires bending the stripped copper wire ends of the wires during connection. During installation, construction workers are prone to skipping this step due to its tediousness, leading to loosening of the wiring after prolonged use. Based on the shortcomings of existing technology, this utility model designs a power unit five-in-one control board power system connection device. Utility Model Content

[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This power unit five-in-one control board power system connection device involves stripping one end of the wire to expose the metal connection end, then attaching a wire guide cover to the wire and inserting the metal connection end into the power connection clamp. The slider at the rear end of the through slot is then pushed forward. The forward-moving slider pushes the upper hinge block and push arm to gradually become vertical under the limitation of the lower hinge block. The lower hinge block pushes the buckle plate downwards, causing the power connection clamp to deform and clamp the metal connection end. After the power connection clamp has clamped the metal connection end, the limiting cover is closed and inserted into the through slot and buckle slot to limit the slider. Finally, the wire guide cover is screwed into the conduit to clamp and fix the wire. This device facilitates quick connection between the power connection clamp and the metal end of the wire.

The through groove 301 is formed through the upper surface of the power receiving box 2, the latching groove 302 is formed through the upper surface of the power receiving box 2, the limiting cover plate 303 is closed and engaged inside the through groove 301 and the latching groove 302, the slider 304 is slidably engaged inside the through groove 301, the conductive plate 305 is fixedly connected to the bottom of the inner cavity of the power receiving box 2, and the power receiving clamp 306 is fixedly connected to the upper hinge block 310. On the upper surface of the circuit board 305, the buckle plate 307 is fixedly snapped onto the upper surface of the electrical clamp plate 306. The lower hinge block 308 is fixedly connected to the upper surface of the buckle plate 307. The bottom end of the push arm 309 is rotatably hinged to the lower hinge block 308. The upper hinge block 310 is rotatably hinged to the top end of the push arm 309. The side wall of the through groove 301 is provided with a side groove, and the slider 304 is slidably snapped into the side groove of the side wall of the through groove 301. The upper hinge block 310 is fixedly connected to the bottom end of the slider 304. The bottom of the limiting cover plate 303 is provided with a locking block, and the locking block at the bottom of the limiting cover plate 303 is snapped into the through groove 301 and contacts the slider 304.
[0023] The conductive plate 305 and the power-connecting clamp 306 are provided to facilitate connection with the wire. The slider 304, the buckle plate 307, the lower hinge block 308, the push arm 309 and the upper hinge block 310 are provided. The slider 304 is slidably connected inside the through groove 301 so as to push the buckle plate 307 to move up and down, thereby controlling the upper part of the power-connecting clamp 306 to clamp and fix the metal connection end of the wire.
[0024] Please see Figure 2 A conduit 201 is fixedly connected to the outside of the junction box 2. A wire guide 202 is threaded onto the conduit 201. The surface of the conduit 201 has a notch, and the inside of the wire guide 202 has a conical tightening structure.
[0025] By setting up the conduit 201 and the wire fixing cover 202, the wires connected to the power connection plate 306 are clamped and fixed to prevent them from being pulled off by external force.
[0026] Working principle: When a power unit five-in-one control board power system connection device is used, in the initial state, the control board body 101 is first placed on the upper surface of the fixed base 1. The power receiving boxes 2 set on both sides of the control board body 101 are equipped with conductive plates 305 and power receiving clamps 306 to facilitate wiring connection with external wires. The buckle plate 307 that is snapped on the power receiving clamp 306 is pulled and pushed by the lower hinge block 308, the push arm 309, the upper hinge block 310 and the slider 304 to control the power receiving clamp 306 to clamp and fix the wires.
[0027] When it is necessary to quickly connect the wire to the power clamp 306, first strip the insulation from one end of the wire to expose the metal connection end. Then, attach the wire guide 202 to the wire and insert the metal connection end into the power clamp 306. At this time, push the slider 304, which is located at the rear end of the through groove 301, forward. The forward-moving slider 304 pushes the upper hinge block 310 and the push arm 309 to gradually become vertical under the limitation of the lower hinge block 308. The lower hinge block 308 pushes the buckle plate 307 down, causing the power clamp 306 to deform and clamp and fix the metal connection end. After the power clamp 306 has completed clamping the metal connection end, close the limiting cover 303 and insert it into the through groove 301 and the buckle groove 302 to limit the slider 304. Finally, screw the wire guide 202 into the conduit 201 to clamp and fix the wire. This device facilitates the quick connection of the power clamp 306 to the metal end of the wire.
