Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of protection of lead-acid batteries, and particularly relates to a protection device for protecting a terminal of a lead-acid battery. BACKGROUND

[0002] With the continuous development of society, batteries are widely used in various fields, such as transportation, power, communication and industry. Today, there are many types of batteries on the market, such as nickel-cadmium batteries, lithium-ion batteries and solar batteries. However, lead-acid batteries play an indispensable role in many fields due to their low cost, high reliability and mature technology.

[0003] Due to certain accidents and potential risks in the actual production and use of the battery, such as transportation collision and external pressure, the terminal of the battery may be deformed or even damaged. The deformed terminal may affect the stability and reliability of the connection, accelerate the damage of the battery, and affect the overall performance and service life of the battery. The severely deformed terminal may cause the internal resistance of the battery to abnormally increase, affect the current transmission efficiency, and may cause safety hazards such as heating and fire, which may bring great inconvenience to the user and greatly reduce the user's experience. SUMMARY

[0004] To solve the above problems, the present application discloses a protection device for protecting a terminal of a lead-acid battery, which comprises a base, and a protective plate is arranged on the upper side of the base. The battery terminal is placed in the base, and then the protective plate is buckled on the upper side of the base to cover the electronic terminal and play a protective role.

[0005] The base comprises two side plates, and the upper end of the side plate is inclined. A supporting plate and a connecting plate are fixedly connected between the two side plates. One end of the side plate is fixedly connected with a back plate, and a first clamping hole is formed in the upper part of the other end of the side plate. When the base is used, one end of the supporting plate abuts against the lower part of the wiring terminal, and the upper end surface of the supporting plate is used to support the inclined wiring terminal.

[0006] The protective plate comprises a plate member, the middle part of the plate member is inclined, and both ends are vertically bent downward. A second clamping hole is formed in one end of the plate member, the first clamping hole and the second clamping hole are matched, and the other end of the plate member is clamped between the back plate and the connecting plate. By means of the first opening, the second clamping hole, and the clamping of one end of the plate member between the back plate and the connecting plate, the fixation of the protective plate is realized.

[0007] Preferably, the back plate is provided with connecting points on both sides, and the connecting points are fixedly connected with the side plates. When the device needs to be removed, the upper connecting points are pulled to break, so that the clamping of the plate member between the connecting plate and the back plate disappears, and the plate member can be conveniently pulled out from the top.

[0008] Preferably, the middle part of the back plate is provided with a buckle groove, one end of the plate member is fixedly connected with a wedge block, and the buckle groove and the wedge block are matched. The wedge block is in the shape of a right triangle in side view, and the wedge block and the buckle groove are adopted to prevent the protective device from falling off during the transportation of the storage battery.

[0009] Further, the base and the guard plate are both formed by injection molding.

[0010] The present application has the following advantages:

[0011] 1. The base and the guard plate are arranged to fix the battery terminal therebetween, thereby protecting the terminal from deformation caused by transportation impact, external pressure and other adverse factors.

[0012] 2. The wedge block and the buckle groove are arranged to prevent the guard plate from falling off due to vibration during transportation, and the back plate is fixedly connected with the side plate through the connecting point, which is convenient to break, so that the side plate is inclined, and the wedge block and the buckle groove are separated, thereby facilitating the removal of the base and the guard plate.

[0022] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0023] like Figures 1 to 6 As shown, a protective device for protecting the terminals of a lead-acid battery includes a base 1. The front of the base 1 is a right-angled trapezoid. A protective plate 2 is fastened to the top of the base 1. The wiring terminals are connected to the inside of the base 1, and then the protective plate 2 is fastened.

[0024] The base 1 includes two side plates 13, and the upper end of the side plates 13 is inclined. A support plate 12 and a connecting plate 14 are fixedly connected between the two side plates 13. When the base 1 is in use, the lower end of the support plate 12 abuts against the lower bend of the terminal block. A back plate 15 is fixedly connected to one end of the side plate 13, and a first latch 11 is opened at the upper part of the other end of the side plate 13.

[0025] The protective plate 2 includes a plate 22. The middle part of the plate 22 is inclined, that is, the upper part of the plate 22 is fitted to the upper part of the base 1. Both ends are bent vertically downward. One end of the plate 22 is provided with a second latch 21. The first latch 11 and the second latch 21 cooperate. When the first latch 11 and the second latch 21 cooperate, the end of the plate 22 and the support plate 12 clamps and fixes the wiring terminal, realizing the connection between the protective device and the wiring terminal. The other end of the plate 22 is clamped and set on the back plate 15 and the connecting plate 14, realizing the fixation of the other end of the plate 22.

[0026] Connection points 17 are provided on both sides of the back plate 15. The connection points 17 are fixedly connected to the side plate 13. When it is necessary to remove the protective device from the terminal block, the back plate 15 is pulled from the top, causing the upper connector 17 to break and the clamping fixation at one end of the plate 22 to disappear. At this time, the protective plate 2 can be easily removed.

[0027] The back plate 15 has a buckle groove 16 in the middle, and a wedge block 23 is fixedly connected to one end of the plate 22. The buckle groove 16 and the wedge block 23 cooperate to prevent the protective device from falling off during the transportation of the battery.

[0028] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
