Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of batteries, in particular to a magnetically-attracted conductive protective plate for a capacitor battery. Background Art
[0002] In the prior art, the lead-out terminals of metal-shell batteries currently designed mostly adopt a split single bowl + wiring terminal structure. This type of metal-shell battery structure is prone to problems such as inconvenient terminal connection, poor connection and connection fit, and loose connection when used. In addition, the two terminals are generally of the same shape, with only printed or pasted positive and negative pole labels. If the user does not see clearly, it is easy to insert the terminals by mistake with the reverse polarity, resulting in a short circuit and burning of electrical equipment.
[0003] Batteries are common electronic components, and their two positive and negative electrodes are both lead-out terminals that extend out of the component body. If they are discarded randomly during waste product processing, or are piled up with other electronic components in garbage classification, or are piled up in metal battery recycling boxes, once the two lead-out terminals touch a metal object or other conductor at the same time, it is easy to cause a short circuit between the terminals and generate a large current, which can burn the terminals and insulating bowl of the product in minor cases, and even burn the entire product or even cause fire and other safety hazards in serious cases.

[0028] Embodiment 1, as Figure 1 , Figure 2 As shown, the thickness of the magnet 5 is equal to that of the protective plate 3, and its upper and lower surfaces are flush with the protective plate 3. The thickness of the guide pin 7 is less than that of the magnet 5 and is sunken and installed in the magnet 5.

The protective plate 3 is made of insulating material, which can be selected as a plastic part. The insulating material of the protective plate 3 contacts the upper half 71 of the guide pin 7, and no circuit conduction is formed to avoid short circuit. The magnet 5 plays the role of fixing the guide pin 7 and identifying the positive and negative poles.

[0031] There are magnets 5 with different polarities under the guide pins 7 of the positive and negative poles, and the corresponding contact surface with the electronic device connected to the battery 1 is also provided with corresponding magnetic poles. If the positive and negative poles are placed correctly, they can be adsorbed to each other and can be easily installed. This makes it convenient to select the positive and negative poles to prevent short circuits, and can also increase a certain adhesion to the contact of the electrodes 2.
[0032] Embodiment 4, as Figure 6 As shown, the battery 1 of this embodiment is a rectangular parallelepiped structure, the protection plate 3 is also a corresponding rectangular parallelepiped, and the structure of the magnet 5 and the guide pin 7 is the same as that of the first embodiment, and the guide pin 7 is completely sunken and installed in the magnet 5.

After being driven in, a magnet 5 is also provided on the outer ring. The magnet 5 is embedded in the protective plate 3. This can be used as an anti-short circuit. Because after the guide pin 7 is driven in, its plane cannot touch other metals and cannot be seen on the plane. It sinks about 0.1-0.2mm. The magnet 5 is protected by insulating material to prevent external metal contact and short circuit.
[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
