Description

Technical Field

[0001] This utility model relates to the field of switch devices, and in particular to a battery terminal fixed automotive power disconnect switch. Background Technology

[0002] A battery switch, which is a switch structure connected to the battery terminal (usually the negative terminal), is generally required when the vehicle is parked for a long time to prevent battery leakage and extend the battery's lifespan.

[0003] Currently, commonly used battery switches include a connector clip that connects to the battery terminals, a conductive plate, and an outward-extending terminal. The connector clip and terminal generally extend horizontally. However, for common five-seater cars, the starter battery is usually located in the engine compartment, such as Buick Excelle and Volkswagen models. In five-seater cars, due to the limited space in the engine compartment (e.g., Buick Excelle), the copper wire connecting to the battery is of fixed length (with limited extension), just enough to plug into the battery terminals. Adding the aforementioned switch to the battery terminals prevents the copper wire from connecting to the switch terminals because the switch terminals extend outwards. Furthermore, the original battery clips have a start-stop connector assembly, and with other body components around the battery, there is almost no space for movement. Adding the aforementioned switch to the battery terminals prevents the battery clip with the start-stop connector assembly from moving outwards to the extended terminal of the switch. Utility Model Content

[0004] The main purpose of this utility model is to provide a battery terminal fixed car power disconnect 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] A battery terminal fixed vehicle power disconnect switch, comprising:

[0007] The connecting clip located at the bottom of the housing is used to connect to the battery terminals;

[0008] and the terminals located on the upper part of the housing;

[0009] The terminals and connectors are aligned vertically and coaxially with the connectors.

[0010] An insulating ring is located between the terminal block and the connector clip;

[0011] The handle, placed on the outside of the insulating ring, controls the circuit connection between the connector and the terminal block.

[0012] Furthermore, the insulating ring, connecting clip, and terminal block are coaxially arranged.

[0013] Furthermore, the handle includes:

[0014] The mounting ring is located outside the insulating ring and can rotate inside the housing;

[0015] The protrusion is located on the inner side wall of the mounting ring;

[0016] The contact spring is movably mounted in the protrusion.

[0017] A spring, located between the contact spring and the side wall of the protrusion, provides an inward elastic force to the contact spring.

[0018] Furthermore, a protruding connecting piece one is fixedly installed on one edge of the connecting clip, and a protruding connecting piece two is fixedly installed on the terminal block;

[0019] A raised strip is fixedly installed on the outside of the insulating ring, and connecting piece one and connecting piece two are located on both sides of the raised strip.

[0020] Furthermore, the inner wall of the protrusion is provided with a mounting groove for installing the spring.

[0021] Furthermore, the height of the connecting clip is lower than the height of the battery terminal.

[0022] Furthermore, when the connecting clip is installed on the battery terminal, the insulating ring and mounting ring are higher than the battery terminal.

[0023] Furthermore, limiting grooves are provided on the upper side of the connecting clip and the bottom side of the terminal block, with the upper and lower ends of the insulating ring located in the two limiting grooves respectively.

[0024] Furthermore, the contact spring has an arc-shaped structure with a notch in the middle, allowing it to rotate with the handle.

[0025] Furthermore, a top cover is provided at the upper end of the housing, and an installation port is opened on one side of the top cover inside the housing. A limiting ring protruding outward is fixedly installed at the bottom of the terminal block, and the limiting ring is coaxially installed with the installation port.

[0026] A hollow shaft is fixedly installed on the top cover, and a locking ring is provided on the limiting ring, which can be locked onto the outside of the hollow shaft.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] This utility model sets the connecting clip and the terminal block vertically, with the handle positioned between the connecting clip and the terminal block. It changes the traditional design where the terminal block extends outward, only raising the terminal block upward. When used in a five-seat car, it does not change the (horizontal) relative position between the terminal block and the car battery copper wire, allowing the original car battery wire to be directly connected to the switch terminal block.

[0039] 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.

[0040] Please see Figure 1-8 As shown, this embodiment provides a battery terminal fixed vehicle power disconnect switch, including:

[0041] Housing 1, with a top cover 4 covering its upper end, such as... Figure 4 As shown.

[0042] The connecting clip 5 is located at the bottom of the housing 1. The connecting clip 5 has an opening, and a bolt is installed on the side of the opening for connecting to the battery terminal. As shown in the figure, a notch is opened on the bottom side of one side of the housing 1, and the bolt of the connecting clip 5 extends out of the notch to the outside.

[0043] Terminal 3 is installed on the upper part of housing 1, and terminal 3 and connecting clip 5 are vertically aligned and coaxially arranged, as shown in the figure. Figure 1 and Figure 2 As shown.

[0044] An insulating ring 9 is located between the terminal block 3 and the connecting clip 5, and is coaxially arranged with the connecting clip 5 and the terminal block 3. Limiting grooves are formed on the upper side of the connecting clip 5 and the bottom side of the terminal block 3. The upper and lower ends of the insulating ring 9 are respectively located in two limiting grooves, as detailed below. Figure 8 As shown.

[0045] Handle 2, fitted over the outside of insulating ring 9 and capable of rotating outside insulating ring 9, is used to control the circuit connection between connecting clip 5 and terminal 3. For example... Figure 1 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, a through hole is provided on the side wall of the housing 1, and the handle 2 is installed inside the housing 1 through the through hole, and the handle 2 can rotate inside the housing 1. The protrusion is smaller than the through hole so that the protrusion can move in the through hole and rotate the handle 2.

[0046] The insulating ring 9 and the handle 2 separate the connecting clip 5 from the terminal block 3.

[0047] In this embodiment, as Figure 3 and Figure 5 As shown, handle 2 includes:

[0048] The mounting ring is located outside the insulating ring 9, is coaxially mounted with the insulating ring 9, and can rotate inside the housing 1;

[0049] The protrusion is integrally formed with the mounting ring (for example, the protrusion is directly stamped or cast during the manufacturing of the mounting ring), and the side of the protrusion facing the mounting ring has a recessed design.

[0050] Contact spring 7 is movably installed in the protrusion, and the shape of contact spring 7 matches the shape of the recess.

[0051] Spring 6 is located between contact spring 7 and the side wall of the protrusion. The side wall of the protrusion has a mounting groove for installing spring 6. One end of spring 6 is located in the mounting groove, and the other end is fixedly connected to contact spring 7, providing elastic force to contact spring 7 toward the center of the mounting ring.

[0052] In this embodiment, as Figures 3-6As shown, a first connecting piece 8 protruding upwards is fixedly installed at the upper edge of the connecting clip 5, and a second connecting piece 11 protruding downwards is fixedly installed at the bottom edge of the terminal block 3. An axially arranged protruding strip 10 is fixedly installed on the outer side of the insulating ring 9. The first connecting piece 8 and the second connecting piece 11 are located on both sides of the protruding strip 10, and the protruding strip 10, the first connecting piece 8, and the second connecting piece 11 are located in the recess of the protruding part. The first connecting piece 8 and the second connecting piece 11 have the same thickness and are located on the same circular surface. In this embodiment, the protruding strip 10 and the insulating ring 9 are made of the same material, such as plastic or insulating ceramic.

[0053] like Figures 2-6 As shown, the contact spring 7 has an arc-shaped structure, with a groove in its center, or a bent portion in its center, bending away from the center to form a groove. The contact spring 7 can move synchronously with the mounting ring of the handle 2. When the handle 2 is rotated to... Figure 6 When in the state, the protrusion 10 is located in the groove. Under the elastic force of the spring 6, the two sides of the contact spring 7 contact and press against the connecting piece 1 8 and the connecting piece 2 11 respectively, realizing the connection between the terminal 3 and the connecting clip 5.

[0054] When handle 2 is turned, contact spring 7 moves with handle 2, the groove separates from the convex strip 10, and the edge of contact spring 7 contacts the convex strip 10, as... Figure 7 In the state shown, the protrusion 10 contacts the edge of the contact spring 7 and lifts the contact spring 7, compresses the spring 6, separates the contact spring 7 from the connecting piece 8, and disconnects the terminal 3 from the connecting clip 5.

[0055] The connecting clip 5 and the housing 1 have mounting holes. A hollow shaft is fixedly installed on the bottom side of the top cover 4. The insulating ring 9 is placed on the connecting clip 5. At the same time, the handle 2 is installed inside the housing 1 from the side. The housing 1 is placed on top of the connecting clip 5. After the terminal 3 and the insulating ring 9 are installed together, the top cover 4 is closed, ensuring that the mounting holes and the hollow shaft insertion holes are aligned. The mounting bolts are directly inserted into the mounting holes and the hollow shaft insertion holes, and the nuts are tightened to complete the switch assembly.

[0056] A limiting ring protruding outward is fixedly installed at the bottom of the terminal block. Symmetrically arranged locking slots are provided on the outer side of the limiting ring, allowing it to engage with the outer side of the hollow shaft. Figure 2 and Figure 4As shown. Since the mounting bolt contacts the connecting clip 5, and the bolt is made of metal and is conductive, to prevent the mounting bolt from connecting the connecting clip 5 and the terminal 3, the top cover 4 and the hollow shaft are both made of insulating plastic. The locking ring contacts the hollow shaft but not the mounting bolt, thus providing insulation and preventing the mounting bolt from connecting the connecting clip 5 and the locking ring.

[0057] In this embodiment, as Figure 8 and Figure 9 As shown, the terminals and connecting clips are set vertically, simply raising the position of the terminals to ensure that the switch can control the circuit's on / off state. This changes the conventional way of setting terminals and connecting clips in battery disconnect switches, resulting in a smaller, more compact overall structure that is more suitable for installation in small spaces.

[0058] 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.
