Description

Technical Field

[0001] The present application relates to the technical field of wiring equipment, and in particular to an instrument terminal. Background Art

[0002] Binding posts are posts on instruments such as ammeters, voltmeters, ohmmeters, and batteries that are used to connect wires and are typically used to test instruments. Some instrument binding posts connect the wires by wrapping them around the post surface and then tightening them with a wire nut. After connecting the wires in this way, the exposed post and wires pose a safety hazard during instrument testing, as both the terminal and wires are live and exposed. Furthermore, after the wires are wrapped, the compression direction of the wire nut is perpendicular to the direction of tension on the wire, so pulling the wire can easily cause it to fall off the post surface, resulting in poor wiring.

[0022] The following embodiments are described in detail, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numbers in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following embodiments are not intended to represent all possible implementations consistent with the present application. They are merely examples of systems and methods consistent with certain aspects of the present application, as detailed in the claims.

[0023] Some instrument terminal blocks connect to the wire by wrapping the wire around the terminal and then clamping it with a wire nut. However, after connecting the wire in this way, both the terminal and the wire are exposed and live during instrument testing, posing a safety hazard. Furthermore, after the wire is wrapped, the compression direction of the wire nut is perpendicular to the direction of tension on the wire, so pulling the wire can easily cause it to fall off the terminal block, resulting in poor connection quality.

[0024] In order to solve the problem of potential safety hazards in the use of the terminal, the embodiment of the present application provides an instrument terminal, see Figure 1-Figure 2 , Figure 1 This is a schematic diagram of the structure of the instrument terminal provided in the embodiment of the present application. Figure 2 This is an enlarged schematic diagram of point A provided in an embodiment of the present application, in which the terminal includes: a base 1, a terminal body 2, a wire nut 4, a protective sleeve 5 and a locking connector 9.

[0025] The base 1 may be a circular plate structure, and the terminal body 2 is arranged on the top surface of the base 1, and the terminal body 2 may be arranged in the center. In some embodiments, in order to facilitate the winding of the wire, the terminal body 2 may be a cylindrical structure, and in order to make the terminal body 2 have better conductivity, the material of the terminal body 2 may be copper. The material of the base 1 may be ordinary carbon steel, and the terminal body 2 may be fixed to the base 1 by welding. It should also be noted that the diameter of the base 1 is larger than the diameter of the terminal body 2 to provide installation space for the protective sleeve 5 described below. A threaded groove 3 is provided on the outer side of the terminal body 2, and the wire pressing nut 4 is detachably connected to the terminal body 2 through the threaded groove 3. By rotating the wire pressing nut 4 to the bottom of the terminal body 2, the wire wrapped around the terminal body 2 can be pressed tightly.

[0026] The bottom of the terminal body 2 is provided with a positioning post 7, which can be fixed to the bottom of the terminal body 2 by welding. By providing the positioning post 7, after the wire is wrapped around the terminal body 2 several times, the winding direction of the wire on the terminal body 2 can be changed by the positioning post 7, making the wire wrapped around the terminal body 2 more secure. At this time, the wire is compressed by the wire nut 4, which can reduce the probability of the wire falling off the terminal body 2.

[0027] The protective sleeve 5 is a hollow cylinder that fits over the outside of the terminal body 2. The protective sleeve 5 provides insulation and protection, thereby reducing safety hazards associated with the exposed terminal body 2 and wires. A connecting cavity 8 is provided on the top surface of the base 1. The bottom of the protective sleeve 5 is plugged into the base 1 through the connecting cavity 8, securing the protective sleeve 5 to the base 1.

[0028] The locking connector 9 is detachably connected to the side of the base 1. For example, a threaded hole can be provided on the side of the base 1 so that the locking connector 9 can be threadedly connected to the base 1. A side wall is formed between the connecting cavity 8 and the outer side of the base 1. One end of the locking connector 9 penetrates the side wall and abuts against the protective sleeve 5. Due to the existence of processing errors, the protective sleeve 5 may shake after being inserted into the connecting cavity 8. By providing the locking connector 9, the protective sleeve 5 can be tightened, further improving the connection stability between the protective sleeve 5 and the base 1, so that the protective sleeve 5 is reliably fixed, and the probability of the protective sleeve 5 falling off during use is reduced.

[0029] The terminal provided in the present application can change the winding direction of the wire on the terminal body 2 by providing the positioning post 7, so as to better wind the wire and reduce the probability of the wire falling off the terminal body 2. By providing the protective cover 5 on the outside of the terminal body 2, the wire can be hidden inside the protective cover 5, thereby improving the safety during instrument detection. By providing the locking connector 9, the protective cover 5 can be reliably fixed, reducing the probability of the protective cover 5 falling off during use, further improving the safety of the terminal when in use, solving the problem of potential safety hazards when using the terminal, and at the same time improving the stability of the terminal after wiring.

[0030] See again Figure 1-Figure 2 In some embodiments, a recess 6 is provided at the bottom of the protective cover 5. The recess 6 is rectangular and facilitates the passage of the wires through the protective cover 5, providing space for the wires to pass through. The recess 6 can also be semicircular. The shape of the recess 6 can be selected based on the diameter of the wires to facilitate the passage of the wires.

[0031] In order to better match the terminal body 2, the cross-section of the protective sleeve 5 can be circular, and the connecting cavity 8 is a hollow cavity with an annular structure, which matches the shape of the protective sleeve 5, so that the bottom of the protective sleeve 5 can be inserted into the connecting cavity 8, so that the protective sleeve 5 and the base 1 can be stably connected. It can be understood that the annular connecting cavity 8 includes a maximum diameter and a minimum diameter, and the diameter of the protective sleeve 5 is between the maximum diameter and the minimum diameter, so that the connecting cavity 8 can be plugged into the base 1. The material of the protective sleeve 5 is an insulating material, such as a plastic material, which can isolate the terminal body 2 and the wire inside, improve the safety of use, and reduce the safety risks of the terminal.

[0032] In some embodiments, there are multiple positioning posts 7, and the multiple positioning posts 7 are evenly arranged at the bottom of the outer side of the terminal body 2. For example, four positioning posts 7 can be set along the outer side of the terminal body 2, and the four positioning posts 7 divide the outer side of the terminal body 2 into four equal parts. When winding the wire, the winding direction of the wire can be changed on any of the positioning posts 7, which can further reduce the probability of the wire falling off the terminal body 2. Figure 2 As shown in , the four positioning posts 7 can be arranged in the same layer, or multiple layers of positioning posts 7 can be provided to wind the wires.

[0033] In some embodiments, a pad is fixedly connected to the outer surface of the base 1, and a connection hole is provided on the pad. The locking connector 9 is detachably connected to the base 1 through the connection hole on the pad. By providing the pad, the contact area between the locking connector 9 and the base 1 can be increased, and the stability of the connection can be improved. The number of the pads is the same as the number of the locking connectors 9, and both are multiple. The multiple pads are evenly arranged on the side of the base 1 so that each locking connector 9 can be stably connected to the base 1 through the pad. By providing multiple locking connectors 9, the protective cover 5 can be better tightened.

[0034] In some embodiments, the thread groove 3 can also be set to a trapezoidal structure. The thread groove 3 with a trapezoidal structure can conveniently fix the positioning column 7, and since the pitch of the thread groove 3 with a trapezoidal structure is greater than the pitch of the standard structure thread, the number of rotations of the wire pressing nut 4 can be reduced, and the wire can be tightened faster.

[0035] During use, the terminal body 2 is fixed to the detection instrument through the base 1, and one end of the wire to be connected is wound in a loop around the bottom of the outer side of the terminal body 2. During the winding process, the winding direction of the wire is changed by the positioning column 7, thereby reducing the probability of the wire falling off the surface of the terminal body 2 when the wire is pulled due to winding around the same direction. After the winding is completed, the wire pressing nut 4 is rotated so that it moves under the action of the thread groove 3 and presses the wound wire to fix the wire in the vertical direction. After the wire is pressed, the insulating sleeve 5 is placed in the connecting cavity 8, and the clearance groove 6 provides a through space for the wire. Thereafter, the insulating sleeve 5 is locked and fixed by the locking bolt 9, so that the insulating sleeve 5 covers and hides the terminal body 2 to reduce the safety hazards caused by the wire being exposed to the outside, and can improve the safety of the instrument detection process while ensuring reliable wiring.

[0036] It can be seen from the above technical solution that the embodiment of the present application provides an instrument terminal, including: a base 1, a terminal body 2, a wire nut 4, a protective sleeve 5 and a locking connector 9. The terminal body 2 is arranged on the top surface of the base 1; the outer side surface of the terminal body 2 is provided with a threaded groove 3, and the wire nut 4 is detachably connected to the terminal body 2 through the threaded groove 3; the bottom of the terminal body 2 is provided with a positioning column 7; the protective sleeve 5 is sleeved on the outer side of the terminal body 2, and a connecting cavity 8 is provided on the top surface of the base 1, and the bottom of the protective sleeve 5 is plugged into the base 1 through the connecting cavity 8; the locking connector 9 is detachably connected to the side of the base 1; a side wall is formed between the connecting cavity 8 and the outer side surface of the base 1, and one end of the locking connector 9 passes through the side wall and abuts against the protective sleeve 5. The terminal provided in the present application can change the winding direction of the wire on the terminal body 2 by setting the positioning column 7, so as to better wind the wire and reduce the probability of the wire falling off the terminal body 2. By providing the protective cover 5 on the outside of the terminal body 2, the wires can be hidden inside the protective cover 5, improving safety during instrument testing. By providing the locking connector 9, the protective cover 5 can be securely fixed, reducing the probability of the protective cover 5 falling off during use, further improving the safety of the terminal when in use, resolving the safety risks that may exist when using the terminal, and also improving the stability of the terminal connection.
