Description

Technical Field

[0001] The present application relates to the technical field of wiring terminals, and in particular to a terminal locking tool. Background Art

[0002] Terminals are the components that connect batteries to external conductors. In electrical engineering, terminals often refer to wiring terminals, also known as terminal blocks. They come in various types, including single-hole, double-hole, socket, and hook. They are also made of materials such as silver-plated copper, zinc-plated copper, copper, aluminum, and iron. They primarily transmit electrical signals or conduct electricity.

[0003] For the split terminal, the split terminal has two terminal heads, and the two terminal heads need to be clamped together. At present, the two terminal heads of the existing split terminal need to be clamped together by the operator with the help of tools such as integrated pliers. However, when the terminal heads are spliced ​​together by tools such as integrated pliers, it is easy to cause the terminal heads to deform, and then cause the connection holes on the terminal heads to deform, affecting the connection and use of the terminals. Utility Model Content

[0004] The present application provides a terminal locking tool to solve the technical problem that existing terminals are easily deformed when spliced.

[0005] The present application provides a terminal locking tool, including a tool body, the tool body including a locking part and an extension part, the extension part is connected to the locking part; the locking part includes a connecting end and an insertion end, the insertion end is connected to the side of the connecting end away from the extension part, the diameter of the connecting end is smaller than the extension part, the diameter of the insertion end gradually decreases in the direction away from the connecting end, and the insertion end is used for the connection hole of the terminal to be sleeved.

[0006] As one of the optional embodiments of this solution, one end of the extension portion facing the locking portion has a limiting surface, and the limiting surface is used to contact the terminal to limit the displacement of the terminal.

[0007] As one of the optional embodiments of this solution, the locking portion and the extending portion are coaxially arranged, and the connecting end and the inserting end are coaxially arranged.

[0008] As one of the optional embodiments of this solution, the side of the insertion end facing away from the connection end is an arc surface.

[0009] As one of the optional embodiments of this solution, it also includes a mounting plate, which is provided with a mounting hole for the extension part to pass through, and the mounting plate and the extension part are detachably connected.

[0010] As one of the optional embodiments of this solution, a thread is provided at one end of the extension away from the locking portion, a nut and a gasket are sleeved on the extension, the nut is threadedly connected to the extension, and the nut is configured to fix the tooling body to the mounting plate.

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

[0025] In the description of this application, it should be noted that, unless otherwise specified or limited, the term "and / or" herein is merely a description of an association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, and B exists alone. Furthermore, the character " / " herein, unless otherwise specified, generally indicates that the associated objects are in an "or" relationship.

[0026] A split terminal has two terminal heads, each with a connection hole. The two terminal heads need to be snapped together so that the connection holes of the two terminal heads overlap. Currently, when splicing the two terminal heads of existing split terminals, operators need to use tools such as pliers to snap them together. However, using tools such as pliers to snap the terminal heads together can easily cause the terminal heads to deform, which in turn causes the connection holes on the terminal heads to deform, affecting the connection and use of the terminal.

[0027] To this end, the present application provides a terminal locking tool, which can realize the clamping connection between two terminal heads, and the terminal heads are not easily deformed during the clamping process. The terminal locking tool provided by the present application is described in detail below.

[0028] See Figure 1 and Figure 2 The terminal locking tool provided in the present application includes a tool body 1, the tool body 1 includes a locking part 2 and an extension part 3, the extension part 3 is connected to the locking part 2, the locking part 2 includes a connecting end 21 and an insertion end 22, the insertion end 22 is connected to the side of the connecting end 21 away from the extension part 3, the diameter of the connecting end 21 is smaller than the extension part 3, the diameter of the insertion end 22 gradually decreases in the direction away from the connecting end 21, and the insertion end 22 is used for the connection hole of the terminal to be sleeved.

[0029] It is understood that in this embodiment, the locking portion 2 and the extension portion 3 are integrally formed, and the connecting end 21 and the insertion end 22 are also integrally formed. In other embodiments, the locking portion 2 and the extension portion 3 may be welded or plugged together, and the connecting end 21 and the insertion end 22 may also be welded or plugged together, which is not limited here.

[0030] By providing an insertion end 22, and gradually reducing its diameter in the direction away from the connection end 21, it is possible to easily fit the terminal's connection hole onto the insertion end 22 from the end with a smaller diameter, and then fit it onto the connection end 21 along the axial movement of the insertion end 22. By fitting the terminal onto the connection end 21, the clamping condition between the terminal and the connection end 21 can be used to determine whether the terminal is clamped into place. If the terminal cannot be clamped into the connection end 21, it indicates that the terminal's connection hole has a smaller aperture. If the terminal has a larger margin on the connection end 21, it indicates that the terminal's connection hole has a larger aperture. This allows for determining whether the two terminals are clamped into place. In addition, the present application clamps the terminal onto the connection end 21 without the need for auxiliary tools such as pliers, which helps ensure that the clamped terminal is not easily deformed, facilitating the connection and use of the terminal.

[0031] Furthermore, the end of the extension portion 3 facing the locking portion 2 has a limiting surface 4, which is used to contact the terminal to limit the terminal's displacement. By providing the limiting surface 4, when the terminal is sleeved on the locking portion 2 and moves to contact the limiting surface 4, the terminal can be restricted from further axial movement, thereby limiting the terminal's position and facilitating operation.

[0032] See Figure 3 and Figure 4 It is understood that in some embodiments, a protective sheet 7 may be provided on the limiting surface 4. The protective sheet 7 is sleeved on the connection end 21 and contacts the limiting surface 4. The protective sheet 7 is preferably made of rubber. When the terminal is sleeved on the connection end 21, the terminal contacts the protective sheet 7, which can minimize contact between the terminal and the limiting surface 4, minimize wear on the terminal, and protect the terminal.

[0033] Furthermore, in this embodiment, the locking portion 2 and the extension portion 3 are coaxially arranged, and the connecting end 21 and the insertion end 22 are coaxially arranged. This coaxial arrangement of the locking portion 2 and the extension portion 3, and the coaxial arrangement of the connecting end 21 and the insertion end 22, facilitates machining of the tool body 1 during production and facilitates fitting the terminal onto the tool body 1. In other embodiments, the axes of the connecting end 21 and the insertion end 22 may be parallel or at an angle, such as 5 to 10 degrees, without limitation.

[0034] Furthermore, in this embodiment, the surface of the insertion end 22 facing away from the connection end 21 is an arcuate surface. This arcuate surface facilitates the installation of the terminal onto the connection end 21 and minimizes collision between the terminal and the insertion end 22 during installation, thereby reducing wear on the terminal and the tool body 1. It will be appreciated that in this embodiment, the portion of the insertion end 22 facing away from the connection end 21 is hemispherical. In other embodiments, this may also be a one-third spherical or conical shape, and this is not intended to be limiting.

[0035] In some embodiments, see Figure 1 The terminal locking fixture further includes a mounting plate 5 for securing the fixture body 1. The mounting plate 5 is provided with a plurality of mounting holes 51. The extension portion 3 of the fixture body 1 is inserted into the mounting holes 51, and the extension portion 3 is detachably connected to the mounting plate 5. Specifically, a thread 6 is provided on the end of the extension portion 3 away from the locking portion 2. A nut 61 and a washer 62 are sleeved on the extension portion 3. The nut 61 is connected to the thread 6 of the extension portion 3. The nut 61 is configured to secure the fixture body 1 to the mounting plate 5.

[0036] The detachable connection between the extension portion 3 of the tool body 1 and the mounting plate 5 facilitates the fixing of the tool body 1. This also facilitates the removal and replacement of the tool body 1, making it easy to operate. The provision of the gasket 62 further strengthens the connection between the tool body 1 and the mounting plate 5, making the connection more stable.

[0037] For further information, see Figures 1 to 4 The mounting plate 5 may be provided with a plurality of mounting holes 51, each of which can accommodate tool bodies 1 of different sizes. This allows multiple tool bodies 1 of different sizes to be simultaneously mounted on the mounting plate 5, each tool body 1 being used to detect terminals of different sizes, thereby improving the adaptability of the terminal locking tool.

[0038] It is understood that in other embodiments, the fixture body 1 and the mounting plate 5 may be connected by a snap-fit ​​or plug-in connection. For example, in other embodiments, the mounting plate 5 is provided with a connecting block (not shown), which has a threaded hole formed therein and can cooperate with the thread 6 of the extension portion 3 to achieve connection. Multiple connecting blocks can be provided, each connecting block being used to connect fixture bodies 1 of different sizes. Different sizes of fixture bodies 1 are used to detect terminals of different sizes, thereby improving the adaptability of the terminal locking fixture.

[0039] In this embodiment, the tool body 1 is made of carbon steel or stainless steel, so that the tool body 1 has strong corrosion resistance and high strength. In other embodiments, alloy materials such as aluminum alloy can also be selected, which is not limited here.

[0040] Furthermore, the surface of the tool body 1 is provided with a protective layer (not shown in the figure), specifically chrome plating, to prevent rusting of the tool body 1 in harsh environments or after prolonged use, thereby extending the service life of the tool body 1. It is understood that before the tool body 1 is put into use, it will undergo a salt spray test to assess its corrosion resistance. Only tool bodies 1 that meet the test requirements can be put into use.

[0041] See Figures 1 to 4 In this embodiment, the side of the insertion end 22 away from the connection end 21 is a hemisphere with a diameter of 3mm. The axial length of the connection end 21 is 13mm, the diameter of the connection end 21 is 6.26mm, the axial length of the extension portion 3 is 135mm, and the diameter is 8mm. The axial length of the thread 6 is 40mm. In this way, multiple terminals can be installed on the connection end 21 at the same time, and multiple terminals can be tested at the same time. After the test is completed, multiple terminals can be removed at the same time, which facilitates operation and helps improve work efficiency. In addition, because the axial length of the thread 6 is 40mm, the position of the tool body 1 on the mounting plate 5 can be adjusted to accommodate a variety of different installation requirements.

[0042] It is easy to understand that the diameters and axial lengths of the insertion end 22 , the connection end 21 , and the extension portion 3 can be adaptively adjusted according to the size of the terminal, and are not limited here.

[0043] To sum up, the tool body 1 provided in the present application is provided with an insertion end 22, and the diameter of the insertion end 22 gradually decreases in the direction away from the connection end 21, so that the connection hole of the terminal can be easily sleeved on the insertion end 22 from the end with a smaller diameter, and sleeved to the connection end 21 along the axial movement of the insertion end 22; by sleeved on the connection end 21, it is possible to detect whether the two terminals are snapped into place, and the terminals after snapping are not easily deformed, so as to facilitate the connection and use of the terminals.

[0044] The above description is only a partial implementation of the embodiments of the present application and does not constitute any form of limitation to the application. The protection scope of the embodiments of the present application is not limited thereto.
