Description

Technical Field

[0001] This utility model relates to the field of switching devices, and in particular to a dual-purpose terminal switch. Background Technology

[0002] A battery switch is a switch structure that is connected to the battery terminals (usually the negative terminal). When the switch is turned off, the power supply to the entire circuit is cut off, which can effectively prevent battery leakage. It is often used in car and ship batteries.

[0003] Different car batteries require different types of disconnect switches due to variations in battery structure. In terms of installation, current car battery disconnect switches have limitations. For small vehicles, the switch is directly fixed to the battery terminals without a bracket. However, for large trucks, space constraints due to the battery cover prevent installation, and the truck disconnect switch cannot be directly fixed to the car battery terminals. Regarding wiring, current disconnect switches on the market typically have two terminals, requiring customers to purchase two wires: one to the negative terminal of the battery, and the other as a ground wire connected to the vehicle frame. Summary of the Invention

[0004] The main purpose of this utility model is to provide a dual-purpose terminal switch, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] Dual-purpose terminal switch, including:

[0007] shell;

[0008] A fixed bracket is attached to one side of the outer casing;

[0009] The inner shell is fixedly installed inside the outer shell;

[0010] A conductive base is fixedly installed inside the inner shell. A clamping bolt is rotatably installed on one side of the conductive base. A first conductive plate and a second conductive plate are fixedly installed on the upper end of the inner shell respectively. The first conductive plate is connected to the clamping bolt.

[0011] The conductive wire is connected to the second conductive plate via a conductive bolt.

[0012] Furthermore, a pressing post is also installed on the outer casing, and a connecting piece is installed at the bottom of the pressing post. When the pressing post is at the bottom, the connecting piece contacts the first conductive piece and the second conductive piece to connect the circuit.

[0013] Furthermore, it also includes terminals that are threaded onto conductive bolts.

[0014] Furthermore, the terminal block has a connection hole.

[0015] Furthermore, the fixing bracket has mounting holes.

[0016] Furthermore, the conductive base has terminal holes for connecting to the battery terminals, and one end of the clamping bolt extends into the terminal hole.

[0017] Furthermore, the clamping bolt extends through the inner shell to the outside, and a clamping plate is rotatably installed at one end of the clamping bolt located in the pole hole.

[0018] Furthermore, a handle is fixedly installed on the top of the pressing column.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This invention features a fixed bracket and a conductive base. The fixed bracket can be directly connected to the original mounting bracket of a large truck, serving as a grounding wire without the need for additional grounding wire. When the terminal block is not installed, only the product with the wire is required; the wire can then be used as a conductive wire to connect to the negative terminal of the battery and can be directly installed on the negative terminal. When the fixed bracket is not in use, it is directly fixed to the original negative terminal of the vehicle using the conductive base. With the terminal block not installed, only the product with the wire is required; the conductive wire can then be used as a grounding wire to connect to the vehicle body. This design is compatible with both small cars and large trucks, reducing limitations. Attached Figure Description

[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 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.

[0031] Please see Figure 1-7 As shown, this embodiment provides a dual-purpose terminal switch, including:

[0032] The outer casing 1 has a fixed bracket 10 fixedly installed on one side. The fixed bracket 10 has mounting holes. By inserting bolts into the mounting holes, the fixed bracket 10 can be directly fixed to the truck.

[0033] The conductive wire 12 has a conductive bolt 11 installed on its upper part. The fixing bracket 10 has a threaded hole that matches the conductive bolt. The conductive bolt 11 is installed in the threaded hole by means of threads, so that the conductive wire 12 and the fixing bracket 10 are installed together.

[0034] The terminal 8 has a threaded hole at its bottom, which is fitted with a conductive bolt 11 to secure the terminal 8 to the bracket 10. Figure 5 As shown. A connection hole 9 is provided on the terminal 8. An external wire or conductive bolt can be inserted into the connection hole 9, and the wire (conductive bolt) will be fixed in the connection hole 9 by bolt (or nut).

[0035] The inner shell 5 is fixedly installed inside the outer shell 1.

[0036] The conductive base 6 is installed inside the inner shell 5, such as... Figure 2 As shown, the conductive base 6 is fixedly installed to the inner shell 5 using bolts. The bottom side of the conductive base 6 has terminal holes that match the battery terminals, allowing it to be inserted into the battery terminals.

[0037] A clamping bolt 7 is rotatably mounted on one side of the conductive base 6. One end of the clamping bolt 7 is located in the terminal hole of the conductive base 6, and an arc-shaped piece is rotatably connected to this end. The arc-shaped piece can contact the battery terminal. The other end passes through the conductive base 6 and the inner shell 5 and extends to the outside of the outer shell 1.

[0038] like Figure 2 , Figures 5-7 As shown, a first conductive plate 4 and a second conductive plate 41 are fixedly installed on the upper end of the inner shell 5. A clamping bolt 7 passes through the first conductive plate 4 and is in contact with it, forming a passage between the clamping bolt 7 and the first conductive plate 4. The second conductive plate 41 has a Z-shaped structure, with one end being a high end and the other end being a low end. The high end is located at the upper end of the inner shell 5 and is flush with the first conductive plate 4. The low end of the second conductive plate 41 is located on the upper side of the inner wall of the fixed bracket 10, and the low end has a threaded hole or mounting hole that matches the conductive bolt 11 of the conductive wire 12. When the conductive bolt 11 of the conductive wire 12 is installed on the fixed bracket 10, the conductive bolt 11 of the conductive wire 12 is connected to the low end of the second conductive plate 41, and the terminal 8 is also connected to the circuit.

[0039] The pressing post 2 has a handle fixedly mounted on its top and a connecting piece 3 mounted on its bottom. The pressing post 2, handle, and connecting piece 3 are configured similarly to existing rotary switches and are considered prior art, so they will not be described in detail here. When the pressing post 2 moves to its bottom position, both ends of the connecting piece 3 contact the first conductive piece 4 and the second conductive piece 41, respectively, connecting the circuit between the first conductive piece 4 and the second conductive piece 41. When the pressing post 2 moves to its top position, both ends of the connecting piece 3 separate from the first conductive piece 4 and the second conductive piece 41, breaking the circuit between them.

[0040] The improvements of this utility model are mainly in two aspects. The first aspect is:

[0041] In terms of installation, the current application of car battery disconnect switches has certain limitations. For small vehicles, the disconnect switch is directly fixed to the battery terminal without a mounting bracket. For large trucks, the batteries have battery covers, which restricts space and makes installation impossible. Furthermore, the disconnect switch for large trucks cannot be directly fixed to the terminal of a car battery disconnect switch.

[0042] This utility model utilizes a fixing bracket 10, which can be directly fixed to a large truck. When the fixing bracket 10 is not in use, it can be directly fixed to the original vehicle's negative terminal using the conductive base 6.

[0043] Secondly, regarding the wiring method, the current market has power-off switches, which all have two terminals. Customers need to purchase two conductive wires, one to connect to the negative terminal of the battery, and the other as a grounding wire to connect to the vehicle frame.

[0044] This application utilizes a fixed bracket 10 to fix the device onto the original vehicle mounting bracket. The conductive base 6 can be directly connected to the original mounting bracket of the truck, serving as a grounding wire, eliminating the need for customers to purchase grounding wire. Simultaneously, the terminal block 8 can be omitted; only the product with the included wire needs to be purchased. In this case, the conductive wire 12 can be used as a conductive wire to connect to the negative terminal of the battery.

[0045] When the mounting bracket 10 is not in use, it can be directly fixed to the original vehicle's negative terminal using the conductive base 6. The terminal 8 does not need to be installed; only the product with the included wire needs to be purchased. In this case, the conductive wire can be used as a grounding wire to connect to the vehicle body.

[0046] For customers whose vehicles already have conductive wires, conductive wire 12 does not need to be installed; only products with terminal blocks 8 need to be purchased.

[0047] 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 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.
