Description

Technical Field

[0001] This utility model relates to the field of switching devices, and in particular to a power-off switch with a dynamically rotatable terminal block. Background Technology

[0002] A battery switch, as a switch structure connected to the battery terminals, is usually directly connected to the positive or negative terminal of the vehicle. The battery switch is connected to the external wiring to facilitate disconnection of the wiring and ensure safe use. It is especially widely used in trucks, where there are more batteries.

[0003] Most existing battery switches use battery connectors that are directly attached to the positive or negative terminal of the battery, with the other end of the connector fixed to the switch for external wiring. Since truck batteries are often installed in the cab or under the cargo box, in close proximity and with limited space, the confined space makes wiring inconvenient.

[0004] For small car batteries, the positive and negative terminals at the top are recessed, and the terminals are located within this recess. For the switches of this type of battery, the terminal clips are typically fixed perpendicular to the length of the switch. Figure 6 As shown, when connected to the battery terminal, it can match the recessed structure at the battery terminal. However, because the connector is set perpendicular to the switch, the direction of the line can only be restricted to one direction when connected, that is, the direction in which the connector extends. When wiring, the reverse direction of the line cannot be flexibly adjusted. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1-7 As shown, this embodiment provides a power-off switch with dynamically rotatable terminals, including:

[0037] The housing 1 and the base plate 2 are located below the housing 1 and are bolted together. A rotation opening 3 is provided between the housing 1 and the base plate 2, as detailed below. Figure 1 and Figure 5 As shown.

[0038] The connecting piece is rotatably mounted at one end in the rotating port 3. The connecting piece can rotate within the rotating port 3, thereby adjusting its position within the port 3 and consequently its orientation on the housing 1. Figure 6 As shown by the middle arrow, the connecting piece can rotate between 0 and 270 degrees on housing 1. The specific angle can be set according to actual usage requirements.

[0039] like Figures 1-7 As shown, there are two connecting pieces. One end of the connecting piece inside the housing 1 has an arc-shaped design, ensuring that it remains in contact with the movable conductive piece 9 when rotating, thus guaranteeing stable contact. Mounting grooves are provided on both sides of the upper end of the base plate 2, and rotating pieces 6 are installed in these grooves, allowing them to rotate within the grooves. Figure 4As shown, a convex ring is fixedly installed at the bottom of the rotating plate 6, and the mounting groove matches the convex ring. When the rotating plate 6 is installed on the base plate 2, the convex ring is located in the mounting groove, which limits the rotating plate 6 so that the rotating plate 6 can rotate, while preventing the rotating plate 6 from falling out of the rotating port 3.

[0040] like Figure 2-4 and Figure 7 As shown, the rotating plate 6 has a groove that matches one end of the connecting plate. An opening is provided on one side of the groove, and one end of the connecting plate is placed into the groove through the opening. The height of the connecting plate is greater than the height of the groove. When the connecting plate is in the groove, the top of the connecting plate is higher than the top surface of the rotating plate 6, so that the connecting plate can contact the movable conductive plate.

[0041] The rotating plate 6 and the two connecting plates each have mounting holes at one end. The aforementioned bolts pass through these mounting holes and are installed coaxially with them. The housing 1, base plate 2, rotating plate, and connecting plates are then assembled together using bolts. In this embodiment, the rotating plate 6 is made of copper, which is relatively soft, has high conductivity, and a smooth surface, making it easier to rotate the connecting plates. Other metal materials can also be used, such as aluminum, zinc-copper alloys, or other conductive metals like aluminum alloys. Other non-metallic materials are also acceptable; no specific limitations are imposed.

[0042] In this embodiment, a wrench can be used to loosen the nut of the bolt, adjust the angle of the connecting piece, and then tighten the nut with the wrench to fix the position of the connecting piece. The connecting piece will not rotate, thus completing the adjustment of the connecting piece.

[0043] The two connecting pieces are designated as first connecting piece 4 and second connecting piece 5. A connecting clip is fixedly installed at one end of the first connecting piece 4 outside the housing 1. The inner diameter of the connecting clip is the same as the diameter of the positive terminal of the battery, and the connecting clip is inserted precisely into the positive terminal of the battery. A removable compensation ring 7 is also placed within the inner circle of the connecting clip. Figure 5-7 As shown, the compensation ring 7 is made of copper and has a circular structure with an opening on one side, resembling a "C" shape. The outer diameter of the compensation ring 7 is the same as the inner diameter of the connecting clip, and the inner diameter of the compensation ring 7 is the same as the diameter of the negative terminal of the battery. The opening of the compensation ring 7 is wider than that of the connecting clip. When the compensation ring 7 is placed inside the connecting clip, its opening is directly opposite the opening of the connecting clip, and the opening of the compensation ring 7 opens outwards to press against the inner ring of the connecting clip, thus achieving the installation of the compensation ring 7 and the connecting clip.

[0044] The second connecting piece 5 has a fixed terminal post at one end located outside the housing. The diameter of the terminal post is the same as that of the negative terminal of the battery, and it can be inserted into the battery clip on the external wiring. The compensation ring 7 can also be removed from the inner ring of the connecting clip and fitted onto the outside of the terminal post, increasing the diameter of the terminal post, and can be connected to the external positive terminal. Since the diameters of the positive and negative terminals of the car battery are different, the diameters of the clips at both ends of the connecting wire are also different. Therefore, the compensation ring 7 designed in this application can only be placed in the inner ring of the first connecting piece 4 or fitted onto the terminal post of the second connecting piece 5 to adapt to the different diameters of the clips at both ends of the connecting wire. The switch can be selectively installed on the positive or negative terminal. Compared with the existing switch connecting clips, which have a fixed diameter and can only be installed on the positive or negative terminal, this application has higher compatibility and is more flexible in use.

[0045] In this embodiment, a threaded post is also fixedly installed on the pole, and a clamping nut 8 is installed on the threaded post via threads. A conductive copper sheet can be fitted onto the outside of the threaded post, and then the clamping nut 8 is used to tighten it, thus fixing the conductive copper sheet. The threaded post and clamping nut 8 facilitate the connection of external circuit leads. When an external circuit is needed, the connecting piece on the external circuit is fitted onto the outside of the threaded post, and the clamping nut 8 is tightened to connect the external circuit and supply power to it. This design is specifically for large trucks or agricultural vehicles, where large trucks must have fans installed inside, or agricultural vehicles must have leads extending out to power other agricultural equipment.

[0046] Because the positive and negative terminals of a battery have different diameters, with the positive terminal generally having a larger diameter than the negative terminal, this is a design standard to facilitate differentiation between positive and negative terminals during installation and avoid confusion. The positive terminal screw is typically 19mm in diameter, while the negative terminal screw is typically 17mm. Therefore, the connecting clip needs to be set with different diameters depending on the installation location (e.g., whether it connects to the positive or negative terminal). In this application, the inner diameter of the connecting clip is 19mm, and the thickness of the compensation ring 7 is 1mm. When the compensation ring 7 is installed inside the connecting clip, the inner diameter of the connecting clip is 17mm, the same as the diameter of the negative terminal, allowing direct connection to the negative terminal. When the compensation ring 7 is removed, the diameter of the connecting clip is 19mm, the same as the outer diameter of the positive terminal, allowing direct connection to the positive terminal. This allows for simultaneous connection to either the positive or negative terminal of the battery. Compared to existing connecting clips with fixed diameters, this design offers greater adaptability and solves the problem that existing connecting clips can only connect to a single terminal, either the positive or negative terminal.

[0047] like Figure 2 , Figure 3 and Figure 7As shown, a handle is installed on the housing 1. The handle is fixedly connected to a support column by bolts. A support bar is fixedly installed on the outer side of the support column. The inner sidewall of the housing 1 has a sloping recess that matches the support bar. The handle can rotate on the housing 1 and move the support column along the sloping recess. A lifting seat 10 is rotatably installed at the lower end of the support column. A spring is installed between the lifting seat 10 and the base plate 2. The lifting seat 10 has an installation port for installing a movable conductive piece 9. A spring is installed between the movable conductive piece 9 and the top of the installation port, and the spring provides a downward elastic force to the movable conductive piece 9. When the handle is rotated to the bottom of the sloping recess, the movable conductive piece 9 is placed at the bottom of the housing, the spring is compressed to its shortest state, and both ends of the movable conductive piece 9 contact the connecting pieces, connecting the two connecting pieces. When the handle is rotated to the top of the sloping recess, the movable conductive piece 9 is placed at the top of the housing, the spring moves the lifting seat 10 up and down, and the two connecting pieces are disconnected. The structure of the handle is consistent with the existing rotary switch, as shown in the figure. Figure 4 As shown, the applicant will not elaborate further here.

[0048] In this embodiment, the lifting seat 10 has been further optimized. The existing lifting seat 10, such as... Figure 8 As shown, the top of the lifting seat 10 has a round hole for insertion into the lifting column. The lifting seat 10 is typically injection molded, requiring core pulling during manufacturing. Due to the round hole design, core pulling is inconvenient. Therefore, in this application, the top of the lifting seat 10 has a U-shaped notch, with the U-shaped opening extending to the edge, as shown... Figure 9 As shown, during injection molding, the mold core can be directly removed from the U-shaped opening, simplifying the manufacturing of the lifting seat 10 and making it suitable for mass production. Simultaneously, since the bottom of the support column is cylindrical, a protrusion is provided at the very bottom of the column. The diameter of the protrusion is the same as the diameter of the U-shaped opening's annulus. The diameters of other parts are larger than the diameter of the U-shaped opening's annulus, allowing for installation with the support column without affecting its normal function. Furthermore, when the support column and lifting seat 10 are installed inside the housing 1, they are limited by the installation space of the housing 1 and can only move up and down. Figure 4 As shown.

[0049] The handle can also adopt a knife switch structure (not shown in the figure). The two terminals of the knife switch are respectively installed on the bolts of the two connecting plates and are in close contact with the connecting plates. The connecting plates can rotate between the knife switch and the base plate 2, thereby adjusting the direction of the connecting plates. The other design of the knife switch structure is consistent with the existing knife switch and adopts the existing technology, which will not be described in detail here.

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 illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
