[0002] Currently, lithium manganese needle batteries are widely used in various small electronic products due to their small size and light weight. They are connected with LED lights to form lighting systems, and are used in electronic products such as night fishing floats, luminous arrow tips, and darts. However, existing lithium manganese needle batteries have the following drawbacks during use:

[0003] 1. Existing lithium manganese needle batteries only have a power supply function at one end. Some electrical appliances that require two lights or different colors of light at the two ends, such as fishing floats and fish attracting lights, have to use two batteries or make another power supply point by welding. This increases the cost, takes up a lot of space, is heavy and inconvenient.

[0004] Second: Existing lithium manganese needle batteries only have a power supply function, which means that they are discarded after the power in the battery is exhausted, making them disposable items with high usage costs and causing environmental pollution, which is not conducive to environmental protection.

[0005] In conclusion, existing batteries cannot meet consumers' needs for simultaneous power supply or simultaneous power supply and charging, and therefore require improvement. Summary of the Invention

[0006] In order to overcome the shortcomings of existing electronic product power supply batteries, such as single-function use, mostly being disposable consumables, resulting in a large amount of battery waste, which is detrimental to environmental protection, and high usage costs, the purpose of this utility model is to provide a battery with conductive pins at both ends, which can realize the function of powering both ends simultaneously or powering one end while charging the other end, thereby improving the service life of batteries in electronic products, reducing energy waste, achieving the goal of protecting the environment, and reducing the usage cost for consumers.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

The negative electrode conductive rod passes through the sealing plug and enters the cavity. The two ends of the negative electrode conductive rod extend out of the sealing plug and extend away from the sealing plug.

[0010] The negative electrode ring is disposed in the cavity and connected to the negative electrode conductive rod, and the positive electrode ring is disposed in the cavity and connected to the outer shell;

[0011] The diaphragm layer is disposed in the cavity and connected to the negative electrode conductive rod. The diaphragm layer divides the cavity into an independent first cavity and a second cavity. The negative electrode ring is disposed in the first cavity, and the positive electrode ring is disposed in the second cavity.

[0012] The conductive medium is located in the second cavity, between the sealing plug and the positive electrode ring.

[0013] Furthermore, the end of the sealing plug protrudes from the end of the outer casing.

[0014] Furthermore, the outer casing is provided with a groove, which is located at the intersection of the outer casing and the sealing plug.

[0015] Furthermore, the negative electrode ring is in the shape of a hollow column, and the negative electrode ring is sleeved on the negative electrode conductive rod.

[0016] Furthermore, there are multiple positive electrode rings, which are sequentially nested on the separator layer.

[0017] Furthermore, the negative electrode conductive rod is provided with an upper limit member and a lower limit member, the upper limit member and the lower limit member are spaced apart, and the negative electrode ring is disposed between the upper limit member and the lower limit member.

[0018] Furthermore, the negative electrode conductive rod is provided with a protrusion, which is located in the middle of the negative electrode conductive rod.

The negative electrode conductive rod passes through the sealing plug so that the middle part of the negative electrode conductive rod is located in the cavity. Both ends of the negative electrode conductive rod protrude out of the outer shell, forming a battery structure with negative electrode conductive rods at both ends. This makes it convenient to supply power to electrical appliances at one end and connect to a charging source at the other end. It can also meet the purpose of connecting electrical appliances at both ends and supplying power at both ends, meeting the usage requirements of timely charging and extending the power supply cycle, and achieving the purpose of reducing energy consumption and saving usage costs.

[0028] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0029] Please see Figures 1 to 3 The present invention provides a battery with conductive needles at both ends, comprising a shell 1, a sealing plug 2, a negative electrode conductive rod 3, a negative electrode ring 4, a separator layer 5, a positive electrode ring 6, and a conductive medium 7.

[0030] The outer shell 1 is a hollow column with openings at both ends. The sealing plug 2 is located at the opening end of the outer shell 1 and forms a cavity with the outer shell 1. The negative electrode conductive rod 3 passes through the sealing plug 2 and enters the cavity. The two ends of the negative electrode conductive rod 3 extend out of the sealing plug 2 and extend away from the sealing plug 2.

[0031] The negative electrode ring 4 is disposed in the cavity and connected to the negative electrode conductive rod 3, and the positive electrode ring 6 is disposed in the cavity and connected to the outer shell 1;

[0032] The diaphragm layer 5 is disposed in the cavity and connected to the negative electrode conductive rod 3. The diaphragm layer 5 divides the cavity into an independent first cavity and a second cavity. The negative electrode ring 4 is disposed in the first cavity, and the positive electrode ring 6 is disposed in the second cavity.

[0033] The conductive medium 7 is located in the second cavity, between the sealing plug 2 and the positive electrode ring 6.

[0034] Specifically, in this embodiment, the outer shell 1 is an aluminum shell structure with openings at both ends. Sealing plugs 2 are inserted into the openings at both ends of the outer shell 1, forming a cavity with the outer shell 1. The sealing plugs 2 have through holes for the negative electrode conductive rod 3 to pass through. The length of the negative electrode conductive rod 3 is greater than the length of the outer shell 1, so that both ends of the negative electrode conductive rod 3 protrude from the sealing plugs 2, i.e., both ends of the negative electrode conductive rod 3 protrude from the two openings of the outer shell 1, forming a battery with negative electrode conductive rods 3 at both ends. A positive electrode ring 6 is provided inside the cavity of the outer shell 1, and the positive electrode ring 6 is attached to the inner surface of the outer shell 1. A hollow cylindrical negative electrode ring 4 is sleeved on the negative electrode conductive rod 3. A separator layer is provided between the negative electrode ring 4 and the positive electrode ring 6. 5. The middle part of the separator layer 5 is wrapped with the negative electrode ring 4, and the two ends of the separator layer 5 are connected to the negative electrode conductive rod 3, so that the negative electrode ring 4 and the positive electrode ring 6 are separated, avoiding the phenomenon of short circuit caused by the shedding of positive and negative electrode powder, improving the life and ensuring quality stability. The cavity of the outer shell 1 is filled with conductive medium 7, which is electrolyte. The setting of the sealing plug 2 can prevent electrolyte leakage. The battery structure with negative electrode conductive rod 3 at both ends makes it convenient to plug an LED light into one end and a power supply into the other end to achieve timely charging and convenient use, and extend the service life of electronic products. Alternatively, an electrical appliance can be connected to each end of the negative electrode conductive rod 3 as needed to achieve the purpose of power supply from both ends.

[0035] By setting an outer shell 1 with openings at both ends, a sealing plug 2 seals the openings at both ends of the outer shell 1 to form a cavity. The negative electrode conductive rod 3 passes through the sealing plug 2 so that the middle part of the negative electrode conductive rod 3 is located in the cavity. Both ends of the negative electrode conductive rod 3 protrude out of the outer shell 1, forming a battery structure with negative electrode conductive rods 3 at both ends. This makes it convenient to supply power to electrical appliances at one end and connect to a charging source at the other end. It can also meet the purpose of connecting electrical appliances at both ends and supplying power at both ends, meeting the usage requirements of timely charging and extending the power supply cycle, and achieving the purpose of reducing energy consumption and saving usage costs.

[0036] The end of the sealing plug 2 protrudes from the end of the outer shell 1. This structure divides the sealing plug 2 into two parts: one part is located inside the outer shell 1, and the other part is located outside the outer shell 1. The sealing plug 2 is made of elastic rubber material. The sealing plug 2 located inside the outer shell 1 is compressed and tightly connected to the outer shell 1, while the sealing plug 2 located outside the outer shell 1 is in a free state. The radial dimension of this part is larger than the inner diameter of the outer shell 1, which means it acts as a cap on the outer shell 1, further improving the sealing effect.

[0037] The outer shell 1 is provided with a groove 11, which is located at the intersection of the outer shell 1 and the sealing plug 2. The groove is arranged in a ring structure around the outer shell 1. Pressure is applied to the outer shell 1 and the sealing plug 2 to form the groove 11, which further improves the connection between the sealing plug 2 and the outer shell 1.

[0038] The negative electrode ring 4 is a hollow column and is sleeved on the negative electrode conductive rod 3 to increase the connection strength and improve conductivity.

[0039] The positive electrode ring 6 is multiple, and the multiple positive electrode rings 6 are sequentially nested on the separator layer 5. This structure facilitates production and assembly and improves production efficiency.

[0040] The negative electrode conductive rod 3 is provided with an upper limit member 31 and a lower limit member 32, and the upper limit member 31 and the lower limit member 32 are spaced apart. The negative electrode ring 4 is disposed between the upper limit member 31 and the lower limit member 32. Preferably, the upper limit member 31 and the lower limit member 32 adopt a ring structure to further ensure that the negative electrode ring 4 and the negative electrode conductive rod 3 are in a relatively stable state after assembly.

[0041] The negative electrode conductive rod 3 is provided with a protrusion 33, which is located in the middle of the negative electrode conductive rod 3. The protrusion 33 is processed by knurling, which increases the friction between the negative electrode conductive rod 3 and the negative electrode ring 4, prevents the negative electrode ring 4 and the negative electrode conductive rod 3 from shifting, and improves the quality stability.

[0042] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
