Description

Technical Field

[0001] This utility model relates to the field of battery connection technology for electrical appliances, and in particular to a convenient battery connection terminal wire, battery-powered electrical appliance, and battery. Background Technology

[0002] In applications such as automobiles, electric wheelchairs, and ships that use lead-acid or lithium batteries, external electrical devices (such as chargers, testing instruments, and inverters) often need to be temporarily or permanently connected to the battery terminals. Current practices primarily rely on round or U-shaped terminals. Circular terminals, such as Figure 1 As shown in Figure A, the terminal nut must be completely removed before it can be inserted and then tightened again. This is not only time-consuming, but also causes the battery to lose power briefly during the removal and installation process. The vehicle's electronic system may lose settings such as clock and Bluetooth pairing (for example, if one device's terminal is removed, the terminals of other devices will lose power briefly. For example, if other device wires are connected to the terminal nut).

[0003] U-shaped terminals, such as Figure 1 Although Figure B shows that the electrode can be inserted with the terminal nut partially loose, it is easily pried out or pulled off the terminal when the nut is tightened or the wire is pulled, resulting in poor reliability. Utility Model Content

[0004] The purpose of this utility model is to provide a convenient way to connect battery terminal wires, battery electrical appliances and batteries, in order to meet the needs of new terminal wires that can be quickly attached, securely locked and prevented from falling off without completely removing the key nut.

[0005] This utility model achieves the above objective through the following technical solution: a convenient battery connection terminal wire, comprising: The cable has a safety catch at one end; The hook, with one end connected to the safety holder, is used to hook the battery terminal from the side. The safety holder is a protective cover. With this design, once the hook of the terminal wire hooks onto the battery terminal, it is impossible to pull the hook or terminal wire out of the battery terminal by pulling the wire itself, greatly improving the reliability and efficiency of connecting and disconnecting terminal wires when connecting an appliance to a battery.

[0006] Furthermore, the hook head is provided with a hook opening, which faces a direction perpendicular to the length direction of the line.

[0007] Furthermore, the hook opening has a C-shaped structure.

[0008] Furthermore, a guide bevel is cut on the side of the hook near the safety position.

[0009] Furthermore, the safety position is equipped with a fuse that is electrically connected to the hook.

[0010] Furthermore, the end of the line away from the hook head is provided with a plug that is electrically connected to an external electrical appliance.

[0011] A battery-powered electrical appliance with terminal wires, wherein the terminal wires are convenient battery connection terminal wires as described in any of the preceding claims; The end of the line away from the hook is electrically connected to an electrical load.

[0012] A battery with terminal wires, wherein the terminal wires are convenient battery connection terminal wires as described in any of the foregoing; The battery includes a terminal post hooked by the hook head, and a releasable locking member locked onto the terminal post; The hook engages with the terminal post and is then locked onto it by the locking mechanism. Specifically, the terminal post can be either a positive or negative terminal. The locking mechanism can be connected to wires from other electrical appliances, such as a clock or memory unit in a vehicle's electronic system.

[0013] Furthermore, the locking component is a clamping and fastening ring, which includes an integrally formed ring body, an elastic slot, and elastic ears. There are two elastic ears, located on either side of the elastic slot. Each elastic ear is equipped with an elastic screw, and the distance between the two elastic ears is adjusted by the elastic screw. The ring body is fitted over the battery terminal and pressed down, causing the bottom of the ring body to press against the hook head. Then, the elastic screw is tightened, thereby clamping the terminal and the hook head.

[0014] Furthermore, the pole post includes a screw structure, and the locking element includes a nut structure threadedly connected to the pole post.

[0015] The beneficial effects of this utility model are: The terminal wire has a hook at the end near the fuse position, which can hook onto the battery terminal from the side. During assembly, it is not necessary to completely remove the locking device (clamping ring or nut) on the terminal; simply loosening it slightly allows the hook to slide into or out of the terminal, thus keeping the battery powered throughout the process and preventing the vehicle's electronic system from "forgetting".

[0016] A hook opening is formed on the hook head, and the hook opening is perpendicular to the length direction of the line; the hook opening is further shaped into a C-shape. When the locking device is tightened or loosened to remove or install the hook head or to pull the line, the hook head is actually more easily pressed tighter, achieving the effect of "the more you pull, the easier it is to lock", which significantly improves the problem of U-shaped terminals easily falling off in the existing technology.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit the present invention. The connection relationships shown in the accompanying drawings are only for clear description and do not limit the connection method.

[0024] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model; the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The terminology used in this specification is only for the purpose of describing specific embodiments and is not intended to limit the invention.

[0025] In related technologies, such as those used in vehicles, electric wheelchairs, ships, and emergency power supplies, external electrical appliances (chargers, detectors, inverters, etc.) typically need to be temporarily or permanently connected to the battery terminals. The current market primarily uses two types of connectors: round terminals and U-shaped terminals. Circular terminals, such as Figure 1 As shown in Figure A, the terminal nut must be completely removed before inserting the terminal, and then the nut must be reinstalled. This is inconvenient for disassembly and assembly, and the disassembly and assembly of the round terminal will cause a brief power outage to the battery. The vehicle's ECU, clock, audio system, etc. are prone to "forgetting". For example, if the terminal nut is loosened to a certain extent, the original vehicle cable or any wire connected to the terminal or the terminal nut will be lifted or loosened, resulting in a brief power outage. In addition, when operating in a narrow engine compartment, there is a high risk of the terminal nut and washer falling off, which increases the difficulty of maintenance.

[0026] U-shaped terminals, such as Figure 1Figure B shows the product details. For further information, please refer to the existing product listings at https: / / shenzhenlijun.en.made-in-china.com / product / gnfrMtGYmacN / China-Car-Battery-Monitor-Bm6-12V-Battery-Tester-Analysis-Simple-and-Cheap-Battery-Tester.html. These U-shaped terminals can be inserted by slightly loosening the nut, but they are prone to slipping when pulling the wire or tightening the nut. Furthermore, most U-shaped terminals lack overcurrent protection between the terminal and the wire; a short circuit in external equipment could cause the wiring harness to overheat or even catch fire.

[0027] In view of the above defects, the industry urgently needs an improved terminal wire 100 that can be quickly connected without power interruption, prevent loosening, and has built-in overcurrent protection and polarity identification functions.

[0028] like Figures 2-5 As shown, this embodiment of the invention provides a convenient battery connection terminal cable 100, including a cable body 1 and a hook head 2. Wherein: Line 1, with a safety stop 11 at one end; Hook 2, one end of which is connected to the safety seat 11, is used to hook the terminal post 31 of the battery 3 from the side. The safety seat 11 is a protective cover. In this solution, the hook 2 of the terminal wire 100 can be quickly hooked onto the terminal post 31 of the battery 3, and after hooking the terminal post 31 of the battery 3, it is impossible to pull the hook 2 or the terminal wire 100 out of the terminal post 31 of the battery 3 by pulling the wire body 1, which greatly improves the reliability and disassembly efficiency of the terminal wire 100 when connected to the battery 3.

[0029] Preferably, the hook head 2 is provided with a hook opening 21, which faces a direction perpendicular to the length direction of the line body 1.

[0030] Preferably, the hook opening 21 has a C-shaped structure.

[0031] Preferably, the hook opening 21 has a guide bevel 22 cut on the side near the safety position 11.

[0032] Preferably, the safety position 11 is provided with a fuse that is electrically connected to the hook head 2.

[0033] Preferably, the end of the line 1 away from the hook head 2 is provided with a plug that can be electrically connected to an external electrical appliance.

[0034] A battery-powered electrical appliance with a terminal wire, wherein the terminal wire 100 is any of the aforementioned convenient battery connection terminal wire 100; The end of the line 1 away from the hook 2 is electrically connected to the electrical load.

[0035] A battery 3 with terminal wires, wherein the terminal wires 100 are any of the aforementioned convenient battery connection terminal wires 100; The battery 3 includes a terminal post 31 hooked by the hook head 2, and a releasable locking member locked onto the terminal post 31; The hook 2 engages with the terminal post 31 and is then locked onto it by the locking member. Specifically, the terminal post 31 can be either a positive or negative terminal post 31. The locking member can be connected to the wires of other electrical appliances, such as the clock or memory of a vehicle's electronic system.

[0036] Preferably, the locking element is a clamping and fastening ring 4, which includes an integrally formed ring body 41, a tension slit 42, and tension lugs 43. There are two tension lugs 43, located on either side of the tension slit 42. Each tension lug 43 is equipped with a tension screw 44, and the distance between the two tension lugs 43 is adjusted by the tension screw 44. The ring body 41 is fitted over the terminal post 31 of the battery 3 and pressed down, causing the bottom of the ring body 41 to press against the hook head 2. Then, the tension screw 44 is tightened, thereby clamping the terminal post 31 and the hook head 2.

[0037] Preferably, the pole post 31 includes a screw structure, and the locking member includes a nut structure threadedly connected to the pole post 31.

[0038] The advantages of this solution compared to existing technologies are as follows: 1. The terminal wire 100 has a hook 2 at one end near the safety position 11. The hook 2 can hook onto the terminal post 31 of the battery 3 from the side. During assembly, it is not necessary to completely remove the locking parts (clamping ring 4 or nut). The hook 2 can be slid into the terminal post 31 or removed from the terminal post 31 by slightly loosening it. Therefore, the battery 3 can remain powered throughout the process, avoiding "memory loss" of the vehicle's electronic system.

[0039] 2. A hook opening 21 is formed on the hook head 2, and the hook opening 21 is perpendicular to the length direction of the line body 1; the hook opening 21 is further shaped into a C-shape. When the locking mechanism is loosened or the hook head 2 is disassembled or the line body 1 is pulled, the hook head 2 is actually more easily pressed tighter, achieving the effect of "the more it is pulled, the easier it is to lock", which significantly improves the existing technology ( Figure 1 The U-shaped terminal (Figure B) is prone to detachment.

[0040] 3. To enable users to quickly insert the device blindly even in a confined cabin, a guide bevel 22 is cut out on the side of the hook 21 near the safety position 11. The bevel serves to automatically align and guide the device during insertion, allowing the hook 2 to slide smoothly into the terminal post 31 even with limited visibility, reducing the risk of misoperation and scratching the terminal post 31.

[0041] 4. One end of the cable body 1 forms a fuse holder 11, and a fuse electrically connected to the hook head 2 is installed inside it. If an external electrical appliance short-circuits or the current abnormally increases, the fuse will blow first, limiting the fault current, preventing the cable body 1 from overheating and catching fire, and protecting the battery 3 and the entire vehicle's electrical system. The fuse holder 11 is located close to the hook head 2, so that the protection action point is as close as possible to the power supply side, and the fuse blows more promptly.

[0042] 5. Intuitive polarity and rated current indication: "+" or "-" and "10A" can be directly embossed on the fuse compartment 11, allowing users to easily identify the polarity and fuse rating, reducing the possibility of incorrect polarity connection due to color fading or label removal.

[0043] 6. Plug-and-play plug: A plug can be installed at the end of the cable 1 away from the hook 2, which can be quickly plugged into external electrical appliances without the need for on-site terminal crimping or wire soldering, shortening wiring time and facilitating testing, maintenance or equipment replacement.

[0044] 7. Two implementation methods for the locking element: For the unthreaded pole post 31, the hook head 2 can be locked by clamping the fastening ring 4; the ring body 41 has a built-in tension slot 42 and a pair of tension lugs 43, and the user can adjust the tension screw 44 to change the inner diameter of the ring body 41, clamping the hook head 2 together with the pole post 31. For the threaded pole post 31, the locking element is a nut structure that directly presses the hook head 2 against the bottom or top surface of the pole post 31. These two solutions cover two types of connecting pole posts 31, improving the versatility of the terminal wire 100.

[0045] Through the above collaborative design, the terminal wire 100 has achieved overall technological progress in terms of uninterrupted and rapid installation and removal, anti-detachment, overcurrent protection, intuitive polarity identification, and wide compatibility with different poles 31. It has significantly reduced the complexity of user operation and electrical safety risks, and has good prospects for industrial application.
