Description

Technical Field

[0001] This utility model relates to the field of battery protection technology, specifically a battery protection device. Background Technology

[0002] In modern society, batteries, as an important energy storage device, are widely used in various fields, such as automobiles, communications, power, and industrial production. Batteries typically have two terminals for connecting to external devices. Through wire connections, the battery can provide a stable power supply to the equipment, ensuring its normal operation.

[0003] During the handling, transportation, and daily use of batteries, protective caps are typically placed on the battery terminals to prevent damage from collisions, friction, and other factors that could affect battery performance and lifespan. Existing battery terminal protective caps do indeed provide a certain degree of protection for the terminals, reducing direct damage from external factors.

[0004] However, current battery terminal protection caps have significant drawbacks. On the one hand, during handling or use, the caps are often easily dropped due to their unstable fixing method, resulting in the caps failing to provide continuous and effective protection for the terminals and increasing the risk of terminal damage.

[0005] On the other hand, existing protective caps have a relatively simple function, merely protecting the battery terminals. In practical use, when the battery terminals need to be connected to wires, existing protective caps cannot secure the connection between the wires and terminals. This means that the protective caps must be discarded each time the battery terminals are connected to a wire. After the connection is completed, these discarded protective caps are often difficult to reuse, resulting in a waste of resources.

[0006] Therefore, developing a new type of battery terminal protection device that can be firmly fixed to the battery terminal, is not easy to fall off, and can effectively fix the connection between the wire and the terminal, avoiding the waste of the protective cap when the wire is connected, has important practical significance and application value. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] In view of the shortcomings of the prior art, this utility model provides a battery protection device that solves the problems mentioned in the background art.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model provides the following technical solution: a battery protection device, including a protective cap, an opening at the bottom of the protective cap through which the battery terminals enter the protective cap, a threaded portion on the outer wall of the middle part of the protective cap, a compression tube threadedly connected to the threaded portion, a compression plate on the side wall of the protective cap, a compression portion on the inner wall of the compression tube, rotating the compression tube causes the compression portion to compress the compression plate, increasing the tension between the compression plate and the battery terminals, a connecting hole for a connecting wire to pass through on the upper side wall of the protective cap, and a fixing member threadedly connected to the top of the protective cap. With the protective cap fixed to the battery terminals, one end of the fixing member compresses the connecting wire with the battery terminals.

[0011] Furthermore, the fastener includes a threaded rod, one end of which is provided with a fixing plate placed in the protective cap, and the other end is provided with a handle.

[0012] Furthermore, the upper part of the inner wall of the extrusion tube is provided with threads, and the lower part of the threads is recessed into the outside of the extrusion tube to form an extrusion section.

[0013] Furthermore, the inner wall of the extrusion plate is coplanar with the inner wall of the protective cap, and the outer wall is a sloping surface.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides a battery protection device with the following advantages:

[0016] I. This battery protection device employs a unique structural design, such as the cooperation between the protective cap, the compression tube, and the compression plate. Through threaded transmission and compression principles, the protection device can be firmly fixed to the battery terminals. Compared to existing protective sleeves that are prone to falling off, this device can remain stably attached to the terminals during handling, transportation, and use, providing continuous and reliable protection. This effectively reduces the risk of damage to the terminals due to external factors such as collisions and friction, greatly improving the protective effect on the battery terminals and extending the battery's service life.

[0017] Second, this battery protection device secures the connection between the wires and terminals without requiring the device to be discarded during connection. After the wire connection is complete, the protection device remains firmly installed on the terminals, continuing to protect them, and can be reused multiple times. This not only reduces resource waste caused by discarding the protective sleeve and lowers operating costs, but also aligns with environmental protection principles, resulting in significant economic and social benefits.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 This utility model discloses a battery protection device, including a protective cap 1, which is the basic protective component of the entire device. Made of plastic, it is cylindrical and possesses good insulation and a certain degree of toughness. Its open bottom design allows it to be easily inserted into the battery terminals, effectively isolating it from impacts and shocks, thereby protecting the battery terminals, extending its service life, and ensuring stable battery performance.

[0024] A threaded section 2 is formed on the outer wall of the protective cap 1. A compression tube 3 is threaded onto the threaded section 2. The upper part of the inner wall of the compression tube 3 is also threaded, with a groove recessed at the lower part of the thread towards the outside of the compression tube 3, forming a compression section 4. This threaded section 2 matches the thread on the upper part of the inner wall of the compression tube 3, providing a crucial connection foundation for fixing the protective cap 1. Simultaneously, multiple annularly distributed compression plates 5 are connected to the outer wall of the protective cap 1. The tops of these compression plates 5 are connected to the protective cap 1, and their inner sides are flush with the inner wall of the protective cap 1, ensuring the regularity of the internal space of the protective cap 1. Their outer walls are sloped, a special design to work in conjunction with the compression section 4 of the compression tube 3. When the compression tube 3 is rotated, it moves downwards along the threaded section 2 of the protective cap 1. At this time, the compression section 4 at the lower part of the inner wall of the compression tube 3 gradually compresses the slope of the compression plate 5. As the extrusion process proceeds, the extrusion plate 5 deforms, thereby increasing the tension between it and the battery terminals, so that the protective cap 1 can be firmly fixed to the battery terminals and is not easy to loosen or fall off even in complex operating environments.

[0025] The extrusion tube 3, as a key component for fixing the protective cap 1, has threads on its upper inner wall that precisely engage with the threaded portion 2 of the protective cap 1. A simple manual rotation allows for vertical movement along the protective cap 1. When moving downwards, the extrusion portion 4 applies pressure to the extrusion plate 5, completing the fixing process of the protective cap 1. The operation is simple and requires no complex tools or specialized skills.

[0026] Furthermore, the connecting hole 6 on the upper side wall of the protective cap 1 provides a channel for the connecting wire to enter the interior of the protective cap 1. After passing through the connecting hole 6, the connecting wire can contact the top of the battery, thereby establishing an electrical connection between the battery and other external devices. The threaded hole on the top of the protective cap 1 and the fixing member 7 mounted thereon further ensure a secure connection of the connecting wire. The fixing member 7 consists of a threaded rod 8, a handle 9, and a fixing plate 10. One end of the threaded rod 8 is connected to the handle 9 for easy rotation by the user; the other end is connected to the fixing plate 10, which is located inside the protective cap 1. When the handle 9 is rotated, the threaded rod 8 rotates in the threaded hole of the protective cap 1, causing the fixing plate 10 to move. Since the pressing plate 5 has already firmly fixed the protective cap 1 to the battery terminals, the fixing plate 10 and the battery terminals together exert a pressing effect on the connecting wire, making the connecting wire firmly fixed and avoiding poor contact caused by loose connection, thus providing a reliable guarantee for the stable connection between the battery and other devices.

[0027] In summary, when using this battery protection device, align the opening of the protective cap 1 with the battery terminals, and slowly and steadily insert the protective cap 1 onto the battery terminals until the protective cap 1 completely covers the terminals, providing initial protection for the terminals.

[0028] Hold the compression tube 3 and align the threads on its upper inner wall with the threads on the outer wall of the protective cap 1. Then rotate the compression tube 3 clockwise. As the compression tube 3 moves downward along the protective cap 1, the compression portion 4 on the lower inner wall of the compression tube 3 will gradually compress the slope of the compression plate 5. Continue rotating the compression tube 3 until sufficient tension is generated between the compression plate 5 and the battery terminals, so that the protective cap 1 is firmly fixed to the battery terminals, ensuring that the protective cap 1 will not easily loosen or fall off during use.

[0029] Take the connecting wire and insert one end of it through the connecting hole 6 on the upper side wall of the protective cap 1 into the protective cap 1, so that the connecting wire makes full contact with the top of the battery, thus establishing the basis for electrical connection.

[0030] Rotating the handle 9 of the fixing component 7 causes the threaded rod 8 to rotate on the protective cap 1 due to its threaded connection with the threaded hole at the top of the protective cap 1. This, in turn, causes the fixing plate 10 connected to the threaded rod 8 to move within the protective cap 1. At this time, since the protective cap 1 is already fixed to the battery terminals by the compression plate 5, as the fixing plate 10 moves, it gradually compresses the connecting wire against the battery terminals until the connecting wire is firmly fixed, ensuring a stable and reliable connection between the connecting wire and the battery, preventing loosening or poor contact.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
