Description

A power monitor that combines quick assembly / disassembly with a secure connection Technical Field

[0001] This utility model relates to the field of power monitoring technology, specifically a power monitor that combines quick assembly / disassembly with a stable connection. Background Technology

[0002] A power supply monitor is a device used to monitor and analyze various parameters of a power system in real time. Currently, it is used to monitor basic parameters of the power supply such as voltage, current, power, and frequency. Based on the monitored parameters, it assesses the working status of the power supply, determines whether there are abnormal conditions such as overload, undervoltage, overvoltage, and leakage, and accurately measures the electrical energy output by the power supply in order to perform energy consumption statistics and cost accounting.

[0003] Currently, the connection between power monitors and power cords typically uses a detachable, movable connection for easy disassembly and maintenance. Existing detachable connection solutions mainly include the following:

[0004] Screw terminal connection: Strip a certain length of the insulation from the end of the power cord to expose the metal wire, and insert the exposed metal wire into the hole of the screw terminal;

[0005] Spring terminal connection: When wiring, first press the button on the spring terminal or use a tool to pry open the spring plate to enlarge the opening of the terminal. Insert the stripped power wire into the terminal, release the button or tool, and the spring plate will automatically return to its original position and clamp the power wire tightly.

[0006] Plug-in connection: Some power monitors use a plug-in connection method, equipped with a special plug and socket, and the end of the power cord is fitted with a plug that matches the socket of the monitoring device.

[0007] Among them, screw terminal connections are the most secure, capable of withstanding a certain amount of tension and vibration, and suitable for various types of power cords. However, during installation, screws need to be tightened one by one with a screwdriver, which takes a lot of time when installing in batches. In comparison, spring terminal connections and plug-in connections are faster and more convenient when connecting power supplies. However, spring terminal connections may cause the power cord to loosen later due to spring aging, while plug-in connections require custom plugs and sockets, which increases product costs. Therefore, a terminal block that can be installed quickly and connected securely is needed. Summary of the Invention

[0008] The purpose of this invention is to provide a power monitor that combines quick installation and secure connection, in order to solve the problem mentioned in the background art that existing terminal blocks cannot simultaneously achieve both quick installation and secure connection.

[0009] To achieve the above objectives, the embodiments of this utility model provide the following technical solutions:

[0010] A power monitor that combines quick assembly / disassembly with a secure connection includes a monitor body and wiring areas at both ends of the monitor body.

[0011] Each wiring area is equipped with a transverse slide that connects to the monitor body. Each transverse slide has a figure-eight slide that is slidably connected to its surface. Two wiring terminals are slidably connected to both sides of the figure-eight slide, and the other end of the wiring terminals extends through the back of the transverse slide.

[0012] A threaded rod is installed in the middle of the two figure-eight slides. By rotating the threaded rod, the two figure-eight slides are driven to slide back and forth along the surface of the transverse slide, so that the terminal block moves back and forth along the transverse slide.

[0013] As a preferred embodiment of this utility model, the surface of the figure-eight slide is provided with a figure-eight groove, and two transverse grooves are provided on the transverse slide corresponding to the position of the figure-eight groove. A protrusion is provided in the middle of the figure-eight slide, and the figure-eight slide slides along the transverse slide through the protrusion.

[0014] As a preferred embodiment of this utility model, wire grooves are installed at both ends of the monitor body near the wiring terminals, and the wire grooves are designed to be bent.

[0015] As a preferred embodiment of this utility model, the wire groove located in the upper middle part of the monitor body is bent upward, and the wire groove located in the lower middle part of the monitor body is bent downward, with an arc-shaped opening provided at the bend of each wire groove.

[0016] As a preferred embodiment of this utility model, the middle part of the terminal block is provided with a protruding strip that fits tightly against the surface of the transverse slide. After the protruding strip slides along the transverse slide, it locks into the arc-shaped opening.

[0017] As a preferred embodiment of this utility model, one end of the terminal block is connected to a lead wire, and the terminal block is electrically connected to the control circuit board inside the monitor body through the lead wire. A metal contact piece is welded to the outer wall on the side near the lead wire, and an auxiliary contact piece is provided at the other end of the wire groove.

[0018] As a preferred embodiment of this utility model, the auxiliary contact piece is provided with a metal gasket inside, and the metal gasket is electrically connected to the metal contact piece.

[0019] As a preferred embodiment of this utility model, the side of the metal contact piece facing the metal pad has an inwardly recessed arc, and the metal pad has an arc that is symmetrical to the metal contact piece.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] In this invention, by driving the figure-eight slides at both ends to move relative to each other, the terminals at both ends can simultaneously expand outward or move towards the center, thereby achieving quick assembly and disassembly and making the installation process more convenient. In addition, during the outward expansion process, the protrusion will simultaneously embed into the arc-shaped opening of the wire groove, pressing and fixing the insulation layer of the power cord. At the same time, the metal contact piece and the auxiliary contact piece tightly wrap the metal wire, achieving double limiting and ensuring a more secure connection, thereby ensuring the current stability of the interface.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please refer to Figures 1 to 5. This utility model provides a power monitor that combines quick assembly and disassembly with a stable connection, including a monitor body 1 and wiring areas 2 disposed at both ends of the monitor body 1.

[0032] Each wiring area 2 is provided with a transverse slide 201 connected to the monitor body 1. Each transverse slide 201 has a figure-eight slide 202 slidably connected to its surface. Two wiring terminals 204 are slidably connected to both sides of the figure-eight slide 202. The other end of the wiring terminal 204 passes through the back of the transverse slide 201.

[0033] A threaded rod 203 is installed in the middle of the two figure-eight slides 202. By rotating the threaded rod 203, the two figure-eight slides 202 are driven to slide back and forth along the surface of the transverse slide 201, so that the terminal 204 can move back and forth along the transverse slide 201.

[0034] It should be noted that the threaded rod 203 drives the figure-eight slides 202 at both ends to move relative to each other, which can simultaneously move towards the middle and cause the terminals 204 at both ends to unfold outward and connect to the power cord. Alternatively, the terminals 204 at both ends can move towards the middle and quickly separate from the power cord, enabling quick disassembly and assembly and making installation more convenient.

[0035] In this embodiment, as shown in Figures 2 and 5, the surface of the figure-eight slide 202 is provided with a figure-eight groove, and two transverse grooves are provided on the transverse slide 201 at the position corresponding to the figure-eight groove. A protrusion is provided in the middle of the figure-eight slide 202, and the figure-eight slide 202 slides along the transverse slide 201 through the protrusion.

[0036] It should be noted that the protrusion is embedded in the middle of the transverse slide 201, restricting the sliding path of the figure-eight slide 202 along the transverse slide 201. The terminal 204 is located at the junction of the figure-eight slide grooves. As the figure-eight slide 202 slides, it drives the two terminal 204 to simultaneously expand outward or move towards the center along the transverse slide groove. When expanding outward, the two terminal 204 move away from each other, pressing and fixing the power cord.

[0037] In this embodiment, as shown in Figures 4 and 5, wire grooves 205 are installed at both ends of the monitor body 1 near the wiring terminals 204, and the wire grooves 205 are bent.

[0038] The wire groove 205 located in the upper middle part of the monitor body 1 bends upward, and the wire groove 205 located in the lower middle part of the monitor body 1 bends downward. An arc-shaped opening is provided at the bend of each wire groove 205.

[0039] The terminal block 204 has a protrusion 206 in the middle that fits tightly against the surface of the transverse slide 201. The protrusion 206 slides along the transverse slide 201 and then locks into the arc-shaped opening.

[0040] It should be noted that one end of the wire groove 205 extends to the outside of the monitor body 1. The wire groove 205 located in the upper part of the monitor body 1 bends upward, while the wire groove 205 located in the lower part of the middle bends downward. The upper opening is used to connect the power cord, and the lower opening is connected to the device to be monitored. When the power cord of the circuit is inserted into the wire groove 205, the bending design at one end of the wire groove 205 guides the inserted power cord to bend synchronously, ensuring that the power cord is limited by the bending point after insertion, so that it is not easy to be accidentally pulled out.

[0041] In addition, the bending angle of the cable tray 205 should be greater than 90° so that the power cord can pass through smoothly. An arc-shaped opening is added at the bend. When the terminal 204 slides close, the protrusion 206 is embedded in the arc-shaped opening, thereby pressing and fixing the bend of the power cord. In this way, the insulation layer at the bend of the power cord is tightly attached to the inner wall of the cable tray 205, and the insulation layer on the outside of the power cord is pressed and limited.

[0042] In this embodiment, as shown in FIG3, one end of the terminal 204 is connected to a lead wire 207. The terminal 204 is electrically connected to the control circuit board inside the monitor body 1 through the lead wire 207. A metal contact piece 208 is welded to the outer wall on the side near the lead wire 207, and an auxiliary contact piece 209 is provided at the other end of the wire groove 205.

[0043] The lead 207 of the terminal 204 is electrically connected to the power supply line, and the power supply line current is transmitted to the control circuit inside the monitor body 1. The control circuit board monitors the current and voltage information in real time.

[0044] The auxiliary contact 209 has a metal pad 2010 inside, and the metal pad 2010 is electrically connected to the metal contact 208.

[0045] The metal contact 208 has an inwardly recessed arc on the side facing the metal pad 2010, and the metal pad 2010 has an arc that is symmetrical to the metal contact 208.

[0046] It should be noted that during the rotation of the threaded rod 203, the terminal 204 will slide to both sides, causing the metal contact 208 to merge and move closer to the position of the metal pad 2010. At this time, the corresponding arcs of the metal contact 208 and the metal pad 2010 approach each other until the exposed metal wire at the end of the power cord is completely wrapped and fixed by the metal contact 208 and the metal pad 2010. The auxiliary contact 209 is made of insulating material, and its purpose is to isolate the inner metal pad 2010, thereby blocking the current.

[0047] The overall design features a wraparound structure, ensuring current transmission even if the metal wire contact point on one side becomes loose, thus guaranteeing the current stability of the interface.

[0048] In practical use, the specific working process is as follows:

[0049] First, insert the main power cord of the circuit into the opening of the upper wire slot 205. Two main power cords can be inserted into the two upper wire slots 205 at the same time. Insert the device to be monitored into the opening of the lower wire slot 205. When wiring, connect the positive and negative terminals in sequence and insert the four power cords into the corresponding wire slots 205 at the same time.

[0050] Next, the fixing process begins. The threaded rod 203, which has two sets of threads (one forward and one reverse), is rotated. As the threaded rod 203 rotates forward, the two figure-eight slides 202 simultaneously move towards the center, driving the upper and lower terminals 204 to expand to both sides. The metal contacts 208 on the sidewalls of each terminal 204 move towards their corresponding metal washers 2010 until the metal wires are completely encased. At this point, the monitor body 1 is connected to the monitoring equipment and the main circuit. The monitor body 1 belongs to... In the prior art, the STY-63TM intelligent power monitor is used to start intelligent monitoring of the current and voltage of the device. At the same time, the protrusion 206 on the outside of the terminal 204 is inserted into the arc-shaped opening, thereby pressing and fixing the bend of the power cord. The upper and lower end limit connection is tighter. When disassembly is required, the threaded rod 203 is rotated counterclockwise, which will drive the two figure-eight slides 202 to unfold to both ends at the same time. The upper terminal 204 and the lower terminal 204 move closer together in the middle, and the power cord can be pulled out.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
