Description

Technical Field

[0001] The utility model relates to the technical field of storage batteries, in particular to a protection cap, a terminal post assembly with the protection cap and a storage battery. Background Art

[0002] A storage battery includes positive and negative terminal posts, and the positive and negative terminal posts extend outwards to the outside of the storage battery to be provided with terminal post heads. At present, there are various types of terminal posts of storage batteries, and both the positive and negative terminal posts are made of conductive metal materials. When the storage battery is placed, if there is no protection cap, its terminal posts are in direct contact with the air, which is likely to cause oxidation of the terminal posts of the storage battery and affect the conductive performance of the storage battery; on the other hand, since the distance between the positive and negative electrodes of some storage batteries is short, if metal components are lapped on the positive and negative terminal posts of the storage battery, it is easy to cause a short circuit between the positive and negative terminal posts of the storage battery, thus triggering an accident. Therefore, most storage batteries are equipped with protective sleeves, and the protective sleeves can effectively protect the positive and negative terminal posts of the storage battery.

[0003] The utility model with the publication number of CN202321058434.8 discloses a terminal post protection cap for a lead-acid storage battery, which specifically discloses a terminal post protection cap for a lead-acid storage battery, including a cap body and a cap brim. The top of the cap body has a top cover and an opening at the bottom. The top cover and the vertical surface of the cap body form a receiving cavity, and the receiving cavity is used to buckle on the terminal post of the storage battery to form protection; the cap brim is located at the opening edge of the cap body and turns outwards in a ring shape; the vertical surface of the cap body has a number of recessed parts arranged at intervals, and all the recessed parts are connected end to end to form a corrugated shape. When the recessed parts are squeezed, they can expand outwards to make the receiving cavity expand. The cap body with small-arc corrugations can be expanded when the terminal post is slightly larger, and the cap body automatically tightens when the terminal post is slightly smaller. The tightness can be self-adapted according to the outer diameter of the end terminal post of the storage battery. The buckling and removal are simple and labor-saving, and at the same time, the adaptability is high. Whether it is a conventional storage battery or a storage battery with a hollow internal thread for the terminal post, it can be adapted.

[0004] The problem of the above protection cap is that over time, the above protection cap will gradually lose the ability of self-adjusting tightness, and finally the protection cap will still fall off, and its stability is not strong enough. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a protection cap, a terminal post assembly with the protection cap and a storage battery. The protection cap utilizes the characteristics of a storage battery with a hollow internal thread for the terminal post to insert the protection cap into the terminal post head, rather than directly sleeving the protection cap on the terminal post head in a conventional way. Therefore, after the protection cap of the present application is inserted into the terminal post head, it is not easy to fall off, and it will not cause the protection cap to fail due to the passage of time, and the safety is high.

[0006] In order to solve the above technical problem, the utility model adopts the following technical solutions:

[0007] A protective cap includes a protective cover and a cap core. The protective cover is sleeved on the pole head, the cap core is arranged in the hollow pole head, and the protective cover and the cap core are fixed.

[0008] Furthermore, a tip is provided at the top of the protective cover.

[0009] Furthermore, a handle is provided at the top of the tip, and the shape of the handle is spherical.

[0010] Furthermore, the protective cover is of a hollow cylindrical structure, the inner diameter of the protective cover is not less than the outer diameter of the pole head, and the height of the protective cover is not lower than the height of the pole head.

[0011] Furthermore, the cap core is columnar, and a fixing ring is arranged on the column body of the cap core.

[0012] Furthermore, the number of the fixing rings is several, and several fixing rings are arranged on the cap core at intervals.

[0013] Furthermore, the outer diameter of the fixing ring is larger than the inner diameter of the pole head.

[0014] Furthermore, the height of the cap core is lower than the height of the pole head.

[0015] The beneficial effects of the present utility model: The present utility model discloses a protective cap, which includes a protective cover and a cap core. The protective cover is sleeved on the pole head, the cap core is arranged in the hollow pole head, and the protective cover and the cap core are fixed. Through the protective cover, the protective cap can be directly inserted into or pulled out from the pole head, and the operation is convenient. Through the cap core, the protective cap can be inserted more stably on the pole head, especially for a storage battery with an internally threaded hollow pole head, so as to realize that the protective cap is not easy to fall off. At the same time, the existence of the protective cover can realize that the protective cap completely covers the pole head made of metal material, avoid its direct contact with air, reduce the oxidation of the pole head, and have higher safety. At the same time, based on the above protective cap, the present utility model also provides a pole assembly and a storage battery with the protective cap, and the pole assembly and the storage battery have better safety than the traditional pole assembly and storage battery.

[0022] Embodiment 1:

[0023] As Figure 1 and Figure 2 shown, a protective cap provided in this embodiment includes a protective cover 2 and a cap core 4. The protective cover 2 is sleeved on the pole head 5, and the cap core 4 is arranged inside the hollow pole head 5. The protective cover 2 and the cap core 4 are fixed. In actual use, the protective cap is used to protect the pole of the storage battery. The protective cap is composed of the protective cover 2 and the cap core 4. Among them, the cap core 4 can be inserted into the pole head 5, and the friction force is increased by the deformation of the cap core 4, so as to prevent the protective cap from falling off the pole head 5 during daily use. The protective cover 2 is used to isolate the external air of the pole head 5, and when the protective cap is inserted into the pole head 5, the contact between the pole head 5 and the external air is reduced, and its oxidation is slowed down.

[0024] In this embodiment, a tip 1 is provided at the top of the protective cover 2. In actual use, the tip 1 is used to facilitate direct manual operation. By pinching the tip 1 of the protective cap, the protective cap can be inserted into the pole head 5 for protection or directly pulled out, which is convenient for operation.

[0025] In this embodiment, a handle 11 is provided at the top of the tip 1, and the shape of the handle 11 is spherical. In actual use, through the handle 11, when inserting and pulling out the protective cap, the operation is convenient and one person can complete the relevant operation.

[0026] In this embodiment, the protective cover 2 is a hollow cylindrical structure. The inner diameter of the protective cover 2 is not less than the outer diameter of the pole head 5, and the height of the protective cover 2 is not lower than the height of the pole head 5. In actual use, the protective cover 2 is mainly used to cover the pole head 5 to avoid the pole head 5 made of metal material from contacting the external air, thereby reducing the oxidation of the pole head 5. The inner diameter of the protective cover 2 not less than the outer diameter of the pole head 5 can ensure the normal use of the protective cover 2, and it can cover the pole head 5. At the same time, the height of the protective cover 2 is not lower than the height of the pole head 5, so that the protective cap can completely cover the pole head 5 after being inserted into the pole head 5, avoiding the pole head 5 from being directly exposed to the air.

[0027] In this embodiment, the cap core 4 is columnar, and a fixing ring 3 is arranged on the column body of the cap core 4. In actual use, the cap core 4 is used to set the fixing ring 3 and connect the protective cover 2. When the cap core 4 is used, it needs to be inserted into the pole head 5. Through the matching use of the cap core 4 and the pole head 5, when the cap core 4 and the fixing ring 3 are inserted into the pole head 5, deformation occurs to increase the friction force.

[0028] In this embodiment, the number of the fixing rings 3 is several, and several fixing rings 3 are arranged on the cap core 4 at intervals. In actual use, several fixing rings 3 are adopted. Several fixing rings 3 are arranged on the cap core 4 to form a multi-layer circular ring structure. When several fixing rings 3 contact the pole head 5, the generated friction force is greater.

[0029] In this embodiment, the outer diameter of the fixing ring 3 is slightly larger than the inner diameter of the pole head 5. In actual use, the outer diameter of the fixing ring 3 is slightly larger than the pole head 5, so that after the fixing ring 3 enters the pole head 5, the fixing ring 3 is deformed, increasing the friction between the protective cap and the pole head 5, so that the fixing ring 3 and the pole head 5 are more stable and not easy to fall off.

[0030] In this embodiment, the height of the cap core 4 is slightly lower than the height of the pole head 5. In actual use, the cap core 4 is used to set the fixing ring 3 and connect the protective cover 2. When in use, the cap core 4 needs to be inserted into the pole head 5. The height of the cap core 4 is slightly lower than the height of the pole head 5, so that the protective cap can be completely inserted into the pole head 51, and the protective cover 2 can be directly in contact with the battery body 5, preventing the pole head 51 from being directly exposed to the air. At the same time, the cap core 4 can be selected with a diameter smaller than the pole head 51, which can reduce the resistance when the protective cap is inserted into the pole head 5, making the operation convenient. At the same time, the diameter of the cap core 4 is reduced, saving energy. The cap core 4 can also be selected with a diameter slightly larger than the pole head 5, so that when the protective cap is inserted into the pole head 5, the cap core 4 and the fixing ring 3 will be deformed, which will be more stable and less likely to fall off.

[0031] Embodiment 2:

[0032] like Figure 1 and Figure 2 As shown, a pole assembly provided in this embodiment includes the protective cover provided in the above-mentioned embodiment 1. In actual use, in order to ensure that the protective cover can be used normally, the pole head 5 needs to adopt a hollow pole head 5, especially a hollow pole head 5 with internal threads. By adopting the hollow pole head 5 with internal threads, when the fixing ring 3 and the cap core 4 are inserted into the pole head 5, the fixing ring 3 and the cap core 4 are deformed at the same time, which greatly increases the friction between the protective cap and the pole head 5, and is not easy to fall off.

[0033] Embodiment 3:

[0034] like Figure 1 and Figure 2 As shown, a battery provided in this embodiment includes the protective cover provided in the above embodiment 1 or at least includes two pole assemblies provided in the above embodiment 2. In actual use, in order to ensure that the battery has better safety during normal use, to slow down the oxidation of the battery pole and affect the conductivity of the battery, and to prevent the positive and negative poles of the battery from being short-circuited due to the overlap of metal parts on the positive and negative poles of the battery, thereby causing accidents, the safety performance of the battery can be well improved by using the protective cap and the pole assembly.
