Description
Technical Field
[0001] The utility model relates to the technical field of batteries, in particular to a tool for charging and discharging tests of cylindrical batteries. Background Art
[0002] In today's rapidly advancing technology, cylindrical batteries, as a common battery form factor, are widely used in various electronic devices. As a key component for energy storage and conversion, battery performance and safety testing are particularly important. Cylindrical battery testing requires frequent charging and discharging. Because cylindrical batteries have two smooth positive and negative terminals, they are not conveniently connected directly to a charger and discharge machine. Therefore, a cylindrical battery charging and discharging tooling has been designed for this purpose. Utility Model Content
[0003] The purpose of the utility model is to provide a tool for charging and discharging cylindrical batteries.
[0004] To achieve the above purpose, the present invention provides the following technical solutions:
[0005] A cylindrical battery charge and discharge test tool comprises a base, a screw, a knob, a first thimble, a second thimble, a thimble fixing part, a wire, and a copper nose; the base is internally provided with a groove, a screw is inserted into the groove, one end of the screw extends out from one side of the base and is connected to the knob, a first thimble and a thimble fixing part are provided above one end of the base, a second thimble and a thimble fixing part are arranged on the screw and can move with the screw, the first thimble and the second thimble are installed inside the thimble fixing part, the first thimble and the second thimble are respectively connected to the positive and negative poles of the cylindrical battery, the wires extending from the rear ends of the first thimble and the second thimble are connected to the copper nose and are connected to the positive and negative terminals corresponding to the charger and discharger.
[0006] Furthermore, the first ejector pin, the second ejector pin and the wire are protected and separated from the metal of the external ejector pin fixing piece by an insulating sealing sleeve, and the ejector pin is provided with a spring that can be retracted to facilitate contact with the positive and negative electrodes of the cylindrical battery.
[0007] Furthermore, by rotating the screw knob to move the position of the second ejector, the distance between the first ejector and the second ejector can be adjusted to facilitate the connection of cylindrical batteries of different sizes.
[0008] The beneficial effects of the present invention are as follows: the cylindrical battery charge and discharge test fixture of the present invention can be connected to cylindrical batteries of different sizes by adjusting the position of the ejector pin on the screw. The wire and copper nose extending from the ejector pin can be easily connected to a charger and discharger for charge and discharge testing, bringing great convenience to the user. The fixture is also low in production cost and simple and easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 It is the front view of the present invention.
[0010] Markings in the figure: 1-base, 2-screw, 3-knob, 4-first thimble, 5-second thimble, 6-thimble fixing, 7-wire, 8-copper nose, 9-insulating sealing sleeve. DETAILED DESCRIPTION
[0011] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.
[0012] like Figure 1 As shown, this embodiment proposes a cylindrical battery charge and discharge test tool, including a base 1, a screw 2, a knob 3, a first thimble 4, a second thimble 5, a thimble fixing part 6, a wire 7, a copper nose 8 and an insulating sealing sleeve 9. A groove is opened inside the base 1, and a screw 2 is installed in the groove. One end of the screw 2 extends out of one side of the base to connect the knob 3. Above the other side of the base 1 are the first thimble 4 and the thimble fixing part 6. The second thimble 5 and the thimble fixing part 6 are installed above the screw 2 and can move with the screw 2. The first thimble 4 and the second thimble 5 are installed inside the thimble fixing part 6. The first thimble 4 and the second thimble 5 are respectively connected to the positive and negative poles of the cylindrical battery. The wires 7 led out from the rear ends of the first thimble 4 and the second thimble 5 are connected to the copper nose 8, and the copper nose 8 is connected to the charger and discharge machine.
[0013] The first ejector pin 4, the second ejector pin 5 and the wire 7 are protected and separated from the metal of the external ejector pin fixing part 6 by an insulating sealing sleeve 9; both ejectors are equipped with springs that can be retracted to facilitate contact with the positive and negative poles of the cylindrical battery.
[0014] When in use, turn the knob to adjust the distance between the first thimble and the second thimble according to the length of the cylindrical battery, place the cylindrical battery between the two thimbles, and the positive and negative poles of the cylindrical battery are in contact with the first thimble and the second thimble respectively. Then use copper noses to connect the wires leading out from the other ends of the first thimble and the second thimble to the positive and negative terminals of the charger and discharger according to the corresponding positive and negative poles. Turn on the charger and discharger to charge and discharge the cylindrical battery.
[0015] The cylindrical battery charge and discharge test tool of the utility model can be connected to cylindrical batteries of different sizes by adjusting the position of the ejector pin on the screw rod, and the wire and copper nose led out of the ejector pin can be conveniently connected to the charger and discharge machine to perform charge and discharge tests, which brings great convenience to the user; and the tool has low production cost and is simple and easy to operate.
