Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium battery power technology, and more specifically to a lithium battery power supply with quick-connect terminals. Background Technology
[0002] With the rapid development of portable electronic devices, power tools, electric vehicles, drones, home energy storage systems, and various industrial backup power supplies, lithium batteries have become the core power source of modern power systems due to their significant advantages such as high energy density, long cycle life, low self-discharge rate, and no memory effect.
[0003] Lithium battery packs are typically composed of multiple individual cells connected in series, parallel, or series-parallel to meet the voltage, capacity, and power requirements of different application scenarios.
[0004] A search revealed a Chinese patent with publication number CN208423050U, which discloses a lithium battery power supply. This device uses a rotating rod to make the movable shaft reciprocate in a circular motion inside a hollow block, allowing the sliding rod to move up and down to pull down the lithium battery casing. Pulling down the lithium battery casing disconnects the wires from the terminals, stopping the charging circuit and minimizing the risk of explosion due to overcharging. The positive and negative leads of the battery pack are directly welded or permanently fixed to external devices or wiring harnesses using screws, resulting in extremely difficult maintenance and poor flexibility.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] Reference Figures 1-4 This utility model provides a lithium battery power supply with quick-connect terminals, including a housing 1, a housing cover 2 mounted on the housing 1, a lithium battery pack 3 installed inside the housing 1, a plurality of recessed openings 4 on one side of the housing 1, a plurality of plug-in terminals 5 for use with the lithium battery pack 3 on one side, and one end of each plug-in terminal 5 being inserted into the recessed opening 4. A prompting component is provided between the plug-in terminals 5 and the lithium battery pack 3 to indicate the plug-in of the plug-in terminals 5. A plurality of slots are provided on the four outer walls of the housing 1, and plastic buckles for use with the slots are provided on the four inner walls of the housing cover 2.
[0025] By setting plug-in terminals 5 on the lithium battery pack 3, the device is made maintainable, flexible and standardized, which facilitates replacement, testing, upgrading and modular design, and simplifies installation.
[0026] The lithium battery pack 3 is formed by connecting multiple individual lithium batteries in series.
[0027] Furthermore, two square openings 8 are provided on the multiple plug terminals 5, and an elastic plate 9 is integrally formed on one side of the square opening 8, and the elastic plate 9 is partially recessed downward.
[0028] The downward concave structure of the elastic plate 9 and the spherical end face of the cylinder 12 form a self-locking force transmission system, which maintains stable contact pressure even under vibration environment, effectively improving the stability of the insertion.
[0029] When in use, when the plug of the external device is inserted into the square opening 8 of the plug terminal 5, it presses against the downward-recessed elastic plate 9.
[0030] In this utility model, the prompting component includes multiple recesses 6 opened on one side of the housing 1, and one side of the lithium battery pack 3 is equipped with the same number of LED tubes 7 as the recesses 6. The LED tubes 7 are LED diode bulbs. One end of the multiple LED tubes 7 is embedded in the recesses 6 respectively. The number of multiple plug terminals 5 is the same as the number of LED tubes 7, and the two correspond one-to-one.
[0031] Furthermore, a U-shaped base 10 is glued to the top outer wall of the plug terminal 5, located above one of the square openings 8. A fixing bracket 13 is glued to the top outer wall of the U-shaped base 10. A miniature push switch 15 (model: DS-318 miniature push switch) is provided on the fixing bracket 13, and the pressing part of the miniature push switch 15 is set downward. A circular hole 11 is opened on the U-shaped base 10, and a cylinder 12 is slidably connected in the circular hole 11. The bottom end of the cylinder 12 contacts the elastic plate 9. The bottom end of the cylinder 12 is set as a sphere, and an insulating layer is coated on the spherical surface of the bottom end of the cylinder 12.
[0032] By triggering the micro push switch 15 to light up the LED tube 7 through the pressure of the plug on the elastic plate 9, an optical indication of the physical connection status is achieved. Users can confirm successful connection without measuring tools, avoiding the risk of loose connection.
[0033] The elastic plate 9 deforms and pushes the contact cylinder 12 upward. Its spherical insulating layer design ensures smooth force transmission and avoids short circuits. The top of the cylinder 12 pushes the slide 14 to compress the spring 16, causing the slide 14 to slide upward and trigger the micro push switch 15. After the micro push switch 15 is closed, the corresponding LED tube 7 lights up and projects visible light outward, indicating that the plug-in terminal 5 is successfully plugged in.
[0034] Furthermore, a slide 14 is slidably connected to the fixed frame 13. The lower surface of the slide 14 is fixed to the top of the cylinder 12. Two springs 16 are welded between the lower surface of the slide 14 and the top outer wall of the U-shaped seat 10.
[0035] After the plug is unplugged, the elastic plate 9 returns to its original shape, pushing the cylinder 12 to move down. The spring 16 releases its stored energy, pushing the slide 14 to reset. The micro push switch 15 pops up and disconnects, the LED tube 7 goes out, and the indicator plug terminal 5 is in the disconnected state.
[0036] The use of this utility model involves the following steps:
[0037] S1: When in use, when the plug of the external device is inserted into the square opening 8 of the plug terminal 5, it presses the downward-recessed elastic plate 9. The elastic plate 9 deforms and pushes the contact cylinder 12 upward. Its spherical insulating layer design ensures smooth force transmission and avoids short circuits. The top of the cylinder 12 pushes the slide 14 to compress the spring 16, causing the slide 14 to slide upward and trigger the micro push switch 15. After the micro push switch 15 is closed, the corresponding LED tube 7 lights up and projects visible light outward to indicate that the plug terminal 5 is successfully plugged in.
[0038] S2: After the plug is unplugged, the elastic plate 9 returns to its original shape, pushes the cylinder 12 to move down, the spring 16 releases its stored energy, pushes the slide 14 to reset, the micro push switch 15 pops up and disconnects, the LED tube 7 goes out, and the indicator plug terminal 5 is in the disconnected state.
[0039] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
