[0001] The utility model relates to the technical field of wiring terminals, in particular to a square U-shaped slot conductor. Background Art

[0002] U-shaped square-shaped wire is commonly used in electrical experiments and circuit connections. When conducting experiments, users often need to rotate the nut on the terminal to create a gap on the terminal so that the square U-shaped plug can be inserted into the terminal. Then, tighten the nut to secure the square U-shaped plug.

[0003] However, during the experiment, due to the small size of the square U-shaped plug, the square U-shaped plug often fails to connect properly when inserted into the terminal. After tightening the nut on the terminal, the square U-shaped plug will fall off after a period of use or have poor contact due to improper connection. Utility Model Content

[0004] (1) Technical problems solved

[0005] In response to the shortcomings of the existing technology, the utility model provides a square U-shaped groove wire, which has the advantages of automatically plugging into place, ensuring connection stability and good contact, and solves the problem that the square U-shaped plug is small in size and often cannot be plugged into place during the process of inserting the square U-shaped plug into the terminal. After the nut on the terminal is tightened, the square U-shaped plug will fall off after a period of use or poor contact will occur due to improper plugging.

[0006] (2) Technical solution

[0007] In order to achieve the above-mentioned automatic plug-in and ensure connection stability and good contact, the utility model provides the following technical solution: a square U-shaped groove wire, including an electric wire and a square U-shaped plug, the square U-shaped plug is connected to one end of the electric wire, and during installation, the square U-shaped plug can be adsorbed on the circumferential surface of the terminal.

[0008] Preferably, the square U-shaped plug includes a square piece and a long insertion piece, one side of the square piece is fixedly connected to the wire, and long insertion pieces are provided on two adjacent corners, and the square piece and the long insertion piece form a U-shaped notch.

[0009] Preferably, a through mounting hole is provided on the square piece, and a through mounting hole is provided on one end of the long insertion piece close to the square piece.

[0010] Preferably, a magnetic sheet is installed in the mounting hole, and the magnetic sheet includes a transition end and a short insertion sheet, and the short insertion sheets are respectively arranged on both sides of the transition end, and the transition end and the short insertion sheet form a second U-shaped notch.

[0011] Preferably, the magnetic sheet is provided with latches, and the latches correspond to the mounting holes one by one.

[0012] Preferably, the pin is inserted into the mounting hole to connect the square U-shaped plug and the magnetic sheet together, and the U-shaped notch 1 and the U-shaped notch 2 overlap with each other.

[0013] Preferably, the square U-shaped plug is magnetic.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the present invention provides a square U-shaped groove conductor with the following beneficial effects:

[0016] The square U-shaped slot conductor is used through the mutual cooperation of the wire, the square U-shaped plug and the magnetic sheet. When the square U-shaped slot conductor is produced, the magnetic sheet is installed on the square U-shaped plug through the pin, or the user installs the magnetic sheet on the square U-shaped plug by himself before use. Before installation, first screw the nut on the threaded column upwards so that a certain gap is left between the copper sheets at the bottom of the nut. Then align the U-shaped slot 1 of the square U-shaped plug with the threaded column to be plugged in and the gap, and insert the square U-shaped plug into the threaded column. At this time, if the user does not plug it into place, the arc surface 2 and the inner side surface 2 on the magnetic sheet respectively coincide with the arc surface 1 and the inner side surface 2 on the square U-shaped plug. The magnetic sheet will generate an attraction to the threaded column, driving the square U-shaped plug that is not plugged into place to automatically fit onto the circumferential surface of the threaded column, so that the arc surface 1 and the inner side surface 1 are in close contact with the threaded column, thereby achieving automatic plugging into place. After the square U-shaped plug is plugged into place, tighten the nut downwards so that the nut presses the conductive surface 2 of the square U-shaped plug tightly against the copper sheet. Because the magnetic sheet previously makes the arc surface 1 and the inner surface 1 of the square U-shaped plug fit tightly against the circumferential surface of the threaded column, making the square sheet closer to the threaded column, when the square U-shaped plug is pressed against the copper sheet, a larger area of the square sheet will also be pressed against the copper sheet, rather than just the long insertion sheet being pressed against the copper sheet, making the connection more stable and the contact better. This not only provides a better effect for subsequent conduction, but also better magnetizes the square U-shaped plug, allowing it to maintain sufficient magnetism, facilitating subsequent operations or experiments. This achieves automatic plugging in place, ensuring connection stability and good contact. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1:

[0026] See also Figure 1-5A square U-shaped slot conductor includes a wire 1 and a square U-shaped plug 2. The square U-shaped plug 2 is connected to one end of the wire 1. During installation, the square U-shaped plug 2 can be adsorbed on the circumferential surface of the terminal. The terminal is a threaded column 4 and a nut 5 for installation. After the square U-shaped plug 2 is adsorbed on the circumferential surface of the threaded column 4, the arc surface 124 of the square U-shaped plug 2 should fit on the circumferential surface of the threaded column 4, and the inner side surface 125 should fit on the circumferential surface of the threaded column 4 in a direction tangent to the arc surface 124. At this time, the square U-shaped plug 2 and the threaded column 4 are in the closest contact. This not only provides a better effect for subsequent conduction, but also can better magnetize the square U-shaped plug 2, so that it maintains sufficient magnetism, which is convenient for subsequent operations or experiments.

[0027] The square U-shaped plug 2 includes a square piece 21 and a long insert piece 22. One side of the square piece 21 is fixedly connected to the wire 1, and the other two adjacent corners of the square piece 21 are provided with long insert pieces 22. The square piece 21 and the long insert pieces 22 form a U-shaped notch 28. The square piece 21 is used to connect to the wire 1 and support the two long insert pieces 22 integrally provided therewith. The U-shaped notch 28 formed by the square piece 21 and the long insert pieces 22 facilitates alignment with the threaded post 4 when the square U-shaped plug 2 is inserted into the threaded post 4, ensuring a certain degree of insertion accuracy. In addition, the square piece 21 and the long insert piece 22 are both made of a conductive material, such as copper.

[0028] The square piece 21 is provided with a through-mounting hole 23, and the long insert piece 22 is provided with a through-mounting hole 23 at one end near the square piece 21. A magnetic sheet 3 is mounted in the mounting hole 23. The magnetic sheet 3 includes an intermediate end 35 and a short insert piece 33. The short insert piece 33 is provided on either side of the intermediate end 35. The intermediate end 35 and the short insert piece 33 form a U-shaped notch 2 36. The mounting hole 23 allows the magnetic sheet 3 to be easily connected to the square U-shaped plug 2 via the pin 34 provided thereon. The pin 34 and the mounting hole 23 have an interference fit. After the user aligns the pin 34 with the corresponding mounting hole 23, pressing the magnetic sheet 3 can connect the magnetic sheet 3 to the square U-shaped plug 2. The magnetic sheet 3 is attached to the conductive surface 1 26 or the conductive surface 2 27 of the square U-shaped plug 2, and the arc surface 2 31 and inner side surface 2 32 of the magnetic sheet 3 respectively overlap with the arc surface 1 24 and inner side surface 1 25 of the square U-shaped plug 2. When the square U-shaped plug 2 is inserted into the threaded post 4, since the magnetic sheet 3 is also U-shaped, as the square U-shaped plug 2 and the magnetic sheet 3 approach the threaded post 4, the magnetic sheet 3 will guide the square U-shaped plug 2 to completely adhere to the circumferential surface of the threaded post 4. After the magnetic sheet 3, the arc surface 2 31, and the inner side surface 2 32 are attached to the circumferential surface of the threaded post 4, the arc surface 1 24 and inner side surface 1 25 of the square U-shaped plug 2 will also tightly fit the circumferential surface of the threaded post 4. At this time, tighten the nut 5 so that the nut 5 presses the square U-shaped plug 2 onto the copper sheet 6 at the bottom, and the conductive surface 2 27 or the conductive surface 1 26 of the square U-shaped plug 2 where the magnetic sheet 3 is not installed fits into the copper sheet 6, thereby achieving circuit conduction.

[0029] In addition, because the magnetic sheet 3 previously made the arc surface 24 and the inner surface 25 of the square U-shaped plug 2 fit tightly against the circumferential surface of the threaded column 4, the square sheet 21 is closer to the threaded column 4. Therefore, when the square U-shaped plug 2 is pressed onto the copper sheet 6, a larger area of the square sheet 21 will also be pressed onto the copper sheet 6, rather than just the long insertion sheet 22 being pressed onto the copper sheet 6, making the connection more stable and the contact better.

[0030] Example 2:

[0031] See also Figure 6 The U-shaped square plug 2 is magnetic. In this embodiment, the magnetic sheet 3 is omitted. Instead, the entire U-shaped square plug 2 is made of a magnetic conductive material, allowing it to adhere to the circumference of the threaded column 4. Materials include nickel oxide, iron oxide, titanium dioxide, and the like.

[0032] Working Principle: When the wires of the square U-shaped plug 2 are manufactured, the magnetic sheet 3 is installed on the square U-shaped plug 2 via the pin 34, or the user can install the magnetic sheet 3 on the square U-shaped plug 2 before use. Before installation, first screw the nut 5 on the threaded column 4 upward, leaving a certain gap between the copper sheet 6 at the bottom of the nut 5. Then, align the U-shaped notch 1 28 of the square U-shaped plug 2 with the threaded column 4 to be plugged in and the gap, and insert the square U-shaped plug 2 into the threaded column 4. If the user does not plug it in properly at this time, the arc surface 2 31 and inner surface 2 32 on the magnetic sheet 3 will overlap with the arc surface 1 24 and inner surface 2 32 on the square U-shaped plug 2, respectively. The magnetic sheet 3 will generate an attractive force on the threaded column 4, causing the square U-shaped plug 2 that is not plugged in properly to automatically fit onto the circumferential surface of the threaded column 4, so that the arc surface 1 24 and inner surface 1 25 are in close contact with the threaded column 4, thereby achieving automatic plug-in. After the square U-shaped plug 2 is plugged into place, the nut 5 is tightened downward so that the nut 5 presses the conductive surface 27 of the square U-shaped plug 2 tightly against the copper sheet 6. Since the magnetic sheet 3 previously makes the arc surface 1 24 and the inner surface 1 25 of the square U-shaped plug 2 fit tightly against the circumferential surface of the threaded column 4, the square sheet 21 is closer to the threaded column 4. Therefore, when the square U-shaped plug 2 is pressed against the copper sheet 6, a larger area of the square sheet 21 will also be pressed against the copper sheet 6, rather than just the long insertion sheet 22 being pressed against the copper sheet 6, making the connection more stable and the contact better. This not only provides a better effect for subsequent conduction, but also better magnetizes the square U-shaped plug 2, allowing it to maintain sufficient magnetism and facilitate subsequent operations or experiments. This achieves automatic plugging in place, ensuring connection stability and good contact.
