Description

Technical Field

[0001] The utility model relates to the technical field of connection terminals, in particular to a power supply driver for a connection terminal with a press and screw function. Background Art

[0002] A terminal block is an accessory used to facilitate the interconnection and conduction of electrical wires. Commonly used terminal blocks are screw-type terminal blocks, which have a wire hole and a threaded hole. The threaded hole is connected to the wire hole, and a threaded part (such as a screw) is inserted into the threaded hole. When in use, one wire is inserted into the wire hole, and the other wire is wrapped around the screw. By tightening the screw, the threaded end of the screw is inserted into the wire hole, and the wire in the wire hole is pressed tightly, so that the inner wire of the wire and the screw are pressed to conduct electricity. This wiring method is also a common solution for power drivers. The power driver converts the mains electricity into a set voltage and current output to supply electrical appliances. Since the wires connected to the mains do not need to be disassembled frequently, it is more cost-effective to use screws to press the wires. However, if the output end of the power driver uses screws to press the wires, in the scenario of frequently changing electrical appliances, the screws need to be constantly turned during the wire connection and disconnection process, which is more inconvenient to use. Utility Model Content

[0003] The purpose of the present invention is to provide a power supply driver for a press-and-screw terminal block to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solutions: a power driver with a press-and-screw terminal block, comprising a power housing, a first insulating seat mounted on the surface of the power housing, a conductive frame fixedly connected to the interior of the first insulating seat, a locking wire threaded through the conductive frame being screwed onto the surface of the conductive frame, the conductive frame serving as the output end of the power driver, and using screws to hold the wires down can reduce the manufacturing and assembly costs of the power driver;

[0005] The second insulating seat is fixed to the left end of the power supply shell surface, and several clamping plates and elastic wiring frames are installed in the second insulating seat. The clamping plate is pressed on the surface of the elastic wiring frame, and the two ends of the elastic wiring frame are connected by a buckling structure. Several anti-retraction springs are fixedly connected to the inner wall of the elastic wiring frame. The anti-retraction springs can press and clamp the wires. Rotating the clamping plate can release the anti-retraction springs, making it easy to remove the wires.

[0006] Furthermore, a cover is rotatably mounted on the surface of the first insulating seat, and the cover can prevent accidental electric shock. A plurality of circular holes are provided on the surface of the cover, and the circular holes are convenient for using an electric pen to measure the circuit.

[0007] Furthermore, a pressing ball integrally formed with the pressing piece is provided on the surface of the pressing piece, and the pressing ball rests on the upper surface of the elastic wiring frame. The pressing ball can reduce the resistance to rotating the pressing piece, making it easier to pry open the pressing piece.

[0008] Furthermore, the buckling structure includes an arc frame and a connecting frame, and the arc frame and the connecting frame are connected to the two ends of the elastic wiring frame. The surface of the arc frame has a socket, and the connecting frame is inserted into the socket and connected to the limiting strip to prevent the elastic wiring frame from being excessively opened.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: the input end of the power drive is connected by means of a locking wire and a conductive frame, which is beneficial to controlling the cost and assembly difficulty of the power drive, and is also convenient for distinguishing the input end and the output end of the power drive; rotating the cover plate separates the pressing ball from the elastic wiring frame, and the elastic wiring frame drives the anti-retraction spring to open, and the wire is smoothly inserted into the elastic wiring frame through the second wire insertion hole, pressing the cover plate resets the elastic wiring frame, and the elastic wiring frame drives the anti-retraction spring to press the wire, making the wiring and disconnection operations of the output end simple.

After the wire is placed at the lower end of the locking wire 17, the locking wire 17 can be twisted to tighten the wire;

[0016] The second insulating seat 6 is fixed to the left end of the surface of the power supply shell 1. Several pressing plates 7 and elastic wiring frames 9 are installed in the second insulating seat 6. The pressing plates 7 are pressed on the surface of the elastic wiring frame 9. The two ends of the elastic wiring frame 9 are connected by a buckling structure. Several anti-retraction springs 11 are fixedly connected to the inner wall of the elastic wiring frame 9. The elastic wiring frame 9 serves as the output end of the power drive. The wires are placed under the anti-retraction springs 11. The anti-retraction springs 11 press the wires. No tools are needed to tighten the screws, and wiring is convenient.

[0017] In this embodiment, if Figure 1 and Figure 2 As shown, a cover plate 4 is rotatably mounted on the surface of the first insulating seat 3. A plurality of circular holes 5 are provided on the surface of the cover plate 4. An electric pen can be inserted into the circular hole 5 to measure whether the locking wire 17 is energized. The cover plate 4 covers the locking wire 17 to avoid electric shock caused by accidentally touching the locking wire 17.

[0021] Specifically, when in use, when the pressing piece 7 is opened in a rotating manner, the pressing ball 18 on the pressing piece 7 is separated from the elastic wiring frame 9, and the elastic wiring frame 9 opens due to its own elastic force, and the elastic wiring frame 9 drives the anti-retraction spring piece 11 to move up, making room for inserting the wire.
