This utility model provides an AC power plug-in device that solves the problem of poor contact between the plug and socket caused by oxidation, deformation, and wear of the metal contacts in existing AC power plug-in devices.
[0004] After investigation and analysis, the patent has the following drawbacks in actual use: The device lacks a cord protection design, and the connection may be loose, leading to poor contact between the power plug and socket. This can cause unstable current, increased resistance, and consequently, overheating or unstable operation of the electrical equipment.
[0005] In summary, this application proposes an AC power plug-in device to solve the aforementioned problems. Utility Model Content
[0006] The purpose of this utility model is to provide an AC power plug-in device that can solve the problem that the device lacks an anti-disconnection design when in use, and the connection wire may not be secure when connected, resulting in poor contact between the power plug and the socket, which can cause unstable current, increased resistance, and consequently overheating or unstable operation of electrical equipment.
[0007] To achieve the above objectives, the present invention provides the following technical solution: an AC power plug-in device, comprising a panel, a clamping assembly, and a detection assembly. The clamping assembly is located on the panel and includes a plug rod, a rectangular block, a socket, spring clips, and a clamping plate. The rectangular blocks are arranged in two sets facing each other. Two sets of spring clips are fixedly connected to one side of the rectangular blocks and arranged front and back. The clamping plate is fixedly installed on the spring clips. The detection assembly is located at the top of the panel.
[0008] Preferably, a rear wiring frame is fixedly connected to the rear side of the panel, and a plug interface is integrally formed on the front side of the panel, which facilitates power-saving operation of the main connection line.
[0009] Preferably, the front side of the panel has a front opening, and the front opening has a rectangular opening, which facilitates the installation of the clamping components.
[0010] Preferably, the bottom of the rectangular block has a socket, and the plug rod is inserted into the socket. The rectangular block is located inside the rectangular opening. When the clamp needs to be replaced, the clamp is lifted outward, which drives the spring clip to lift outward, and the spring clip drives the rectangular block to lift outward, so that the socket on the rectangular block separates from the plug rod. Then, the new rectangular block is picked up, so that the rectangular block drives the socket to insert into the plug rod for connection, ensuring the clamping effect on one end of the main connecting wire. Through the cooperation of the plug rod, rectangular block, socket, spring clip and clamp, the contact between the main connecting wire and the socket can be ensured, avoiding problems such as unstable current and overheating caused by poor contact, improving the safety and reliability of electrical connection. Moreover, by clamping the main connecting wire, when the main connecting wire is subjected to external forces, the connection is protected.
[0011] Preferably, the detection component includes a detection box and indicator lights. The detection box is fixedly connected to the top of the panel, and an indicator light is provided on the front side of the detection box. The indicator lights are arranged in two sets facing each other, one set is red and the other set is green. A green light indicates that the connection voltage is stable, and a red light indicates that the connection voltage is unstable. By using the detection box and indicator lights together, the pressure of the main connection line can be detected. By detecting whether the wire is under excessive pressure, it is possible to detect wear, breakage or insulation damage of the wire in time. The indicator lights can remind the user to take measures to prevent electrical fires or equipment damage.
[0012] Preferably, the surface of the panel is tilted at 33° to facilitate the plugging and unplugging of the main connection cable by the operator.
[0013] Compared with the prior art, the beneficial effects of this utility model are: This AC power plug-in device, through the combined use of plug rods, rectangular blocks, sockets, spring clips, and clamping plates, ensures tight contact between the main connection line and the socket, avoiding problems such as unstable current and overheating caused by poor contact, thus improving the safety and reliability of the electrical connection. Furthermore, by clamping the main connection line, the clamping assembly can effectively prevent the connector from loosening or breaking when the main connection line is subjected to external vibration or tension, maintaining a stable connection.
[0014] This AC power plug-in device, through the combined use of the detection box and indicator lights, can detect the pressure of the main connection line. By detecting whether the wire is under excessive pressure, it can promptly detect possible wear, breakage, or insulation damage to the wire. The indicator lights can remind users to take measures to prevent electrical fires or equipment damage. Attached Figure Description

[0018] Please see Figure 1-3This utility model provides a technical solution: an AC power plug-in device, including a panel 1, a clamping assembly, and a detection assembly. A rear wiring frame 2 is fixedly connected to the rear side of the panel 1. A plug-in interface 3 is integrally formed on the front side of the panel 1, which facilitates energy-saving operation of the main connection cable. A front opening 4 is provided on the front side of the panel 1, and a rectangular opening 5 is provided on the front opening 4, which facilitates the installation of the clamping assembly. The surface of the panel 1 is inclined at 33°, which facilitates the plugging and unplugging of the main connection cable by the operator. The clamping assembly is located on the panel 1 and includes a plug rod 6, a rectangular block 7, a plug 8, a spring clip 9, and a clamping plate 10. The rectangular blocks 7 are arranged in two sets facing each other, and one side of the rectangular block 7 is fixed. The fixed connection has two sets of spring clips 9 arranged front and back. A clamping plate 10 is fixedly installed on the spring clips 9. A recess 8 is opened at the bottom of the rectangular block 7, and a plug rod 6 is inserted into the recess 8. The rectangular block 7 is located inside the rectangular opening 5. When the clamping plate 10 needs to be replaced, it is lifted outwards. The clamping plate 10 drives the spring clips 9 outwards, which in turn drives the rectangular block 7 outwards, separating the recess 8 on the rectangular block 7 from the plug rod 6. Then, the new rectangular block 7 is picked up, allowing the recess 8 to be inserted into the plug rod 6 for connection, ensuring a clamping effect on one end of the main connecting cable. In use, one end of the main connecting cable is inserted into the connector 3. At this time, one end of the main connecting cable is clamped against the clamping plate 10. The clamping plate 10 compresses and causes the spring clip 9 to retract until one end of the main connecting wire is fully inserted into the socket 3. The clamping plate 10 clamps it tightly through the spring clip 9. The cooperation of the plug rod 6, rectangular block 7, socket 8, spring clip 9 and clamping plate 10 ensures a tight contact between the main connecting wire and the socket 3, avoiding problems such as unstable current and overheating caused by poor contact, thus improving the safety and reliability of the electrical connection. Furthermore, by clamping the main connecting wire, when the main connecting wire is subjected to external forces, the detection component is located at the top of the panel 1. The detection component includes a detection box 11 and an indicator light 12. The detection box 11 is fixedly connected to the top of the panel 1, and the front side of the detection box 11 is provided with... The indicator lights 12 are arranged in two sets opposite each other, one set being red and the other green. A green light indicates a stable connection voltage, while a red light indicates an unstable connection voltage. After the main connection line is installed, the indicator lights 12 on the detection box 11 will light up green. When there is a problem with the voltage of the main connection line, the indicator lights 12 on the detection box 11 will light up red, reminding workers to carry out maintenance. Through the combined use of the detection box 11 and the indicator lights 12, the pressure of the main connection line can be detected. By detecting whether the wire is under excessive pressure, it is possible to detect wear, damage, or insulation damage to the wire in a timely manner. The setting of the indicator lights 12 can remind users to take measures to prevent electrical fires or equipment damage.
[0019] Working principle: When in use, one end of the main connecting cable is inserted into the plug interface 3. At this time, the one end of the main connecting cable presses against the clamping plate 10. The pressing of the clamping plate 10 causes the spring clip 9 to retract until one end of the main connecting cable is fully inserted into the plug interface 3. The clamping plate 10 clamps it tightly through the spring clip 9. At this time, the indicator light 12 on the detection box 11 lights up green. When there is a problem with the voltage of the main connecting cable, the indicator light 12 on the detection box 11 lights up red to remind the worker to carry out maintenance.
[0020] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
