Detailed Implementation

[0024] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0025] A combined terminal insulation protection device for lithium-ion batteries is disclosed to protect the terminals of lithium-ion batteries during installation and transportation. By using a protective component to enclose the terminal portion of the lithium-ion battery, it prevents short circuit damage caused by impacts to the external environment or accidental contact with other battery electrodes. The protective component uses non-conductive materials such as PVC and rubber to completely cover the lithium-ion battery terminal portion and conductive platform within the protective component and cover, offering convenient use and excellent protection.

[0026] refer to Figures 1-2 As shown, the lithium-ion battery includes a battery casing 1, a conductive platform base 2, and conductive bolts 203. The conductive bolts 203 are inserted into the battery cells inside the battery casing 1 and are fixedly connected to the conductive platform base 2. A conductive assembly, which is existing technology, is provided on the conductive platform base 2 to fix the conductive bolts 203 to the battery casing 1. A protective assembly is installed on the conductive assembly to cover and protect it, preventing accidental contact and impacts, and to fix the protective assembly to the conductive assembly.

[0027] refer to Figures 1-2As shown, the conductive component includes a conductive platform plate 201 and conductive platform protrusions 202. The conductive platform base 2, conductive platform plate 201, and conductive platform protrusions 202 are all prior art. A protective shell 3 is installed on the conductive platform base 2. The lower end face of the protective shell 3 and the upper end face of the conductive platform base 2 are on the same plane, that is, the protective shell 3 covers the conductive platform base 2, covering the conductive platform plate 201 below the protective shell 3. A groove 304 is formed on the protective shell 3. The groove 304 mates with the conductive platform plate 201. The groove 304 is slightly larger than the conductive platform plate 201, and the conductive platform plate 201 is engaged inside the groove 304.

[0028] refer to Figures 5-6 As shown, a protective hole 302 is provided at the bottom of the groove 304. The protective hole 302 cooperates with the conductive platform protrusion 202. During the process of the conductive platform plate 201 being placed into the groove 304, the conductive platform protrusion 202 installed on the upper end face of the conductive platform plate 201 is placed into the protective hole 302 in the groove 304. The conductive platform protrusion 202 plays a role in positioning and restricting lateral displacement of the protective housing 3. After the conductive platform plate 201 is placed into the groove 304 and the conductive platform protrusion 202 is placed into the protective hole 302, the lower end face of the protective housing 3 is on the same plane as the upper end face of the conductive platform base 2. That is, the protective housing 3 covers the conductive platform plate 201 and the conductive platform protrusion 202 inside and provides protection for them.

[0029] refer to Figures 3-6 As shown, when the protective housing 3 covers the conductive platform plate 201 and the conductive platform protrusion 202, the conductive bolt 203, which is fixedly connected to the conductive component, penetrates through the protective housing 3. A through hole 303 is provided at the bottom of the groove 304, which mates with the conductive bolt 203, allowing the conductive bolt 203 to pass through the through hole 303 and through the protective housing 3. A protective sleeve 6, which mates with the conductive bolt 203, is installed on the protective housing 3. The protective sleeve 6 covers and protects the conductive bolt 203, preventing it from short-circuiting with other batteries during transportation. The conductive bolt 203 has an external thread 2031, and the protective sleeve 6 has an internal thread 602. The internal thread 602 and the external thread 2031 mate, forming a threaded connection between the protective sleeve 6 and the conductive bolt 203.

[0030] A connecting assembly is provided between the protective sleeve 6 and the protective component, which includes a rotating ring 5, a connecting strip 501, and a collar 502. A pair of fixing blocks 4 are fixedly connected to the upper end face of the protective shell 3, and a fixing shaft 401 is fixedly connected between the pair of fixing blocks 4. The rotating ring 5 is sleeved on the fixing shaft 401 and can rotate around the fixing shaft 401. A connecting strip 501 is fixedly connected to the rotating ring 5. The connecting strip 501 is made of elastic rubber and can move, stretch, and deform. A collar 502 is fixedly connected to the connecting strip 501. The protective sleeve 6 is provided with a connecting ring 601 that cooperates with the collar 502. The connecting ring 601 can be snapped into the collar 502.

[0031] refer to Figures 3-6 As shown, the protective sleeve 6 is fitted inside the collar 502 via a connecting ring 601. The protective sleeve 6 can rotate around the inside of the collar 502. The collar 502 is connected to the fixed shaft 401 via a connecting strip 501 and a rotating ring 5. The connecting strip 501 can prevent the protective sleeve 6 from being lost when it is not installed on the conductive bolt 203. At the same time, depending on the site conditions, the protective sleeve 6 can be either snapped into the inside of the collar 502 or pulled out from the collar 502.

[0032] The protective housing 3 has a positioning hole 301, and a soft clip 7 is installed in the positioning hole 301. The soft clip 7 is equipped with a soft plug 701 and a pinch block 702. The soft clip 7, soft plug 701, and pinch block 702 are all made of soft silicone. The soft clip 7 inserts the soft plug 701 into the groove 304 through the positioning hole 301. The soft plug 701 has a semi-circular outline. It deforms and is squeezed when passing through the positioning hole 301. When it enters the groove 304, it returns to its shape and is locked in place on the side of the positioning hole 301 near the groove 304. By pressing the pinch block 702 at one end of the soft clip 7, the soft plug 701 is pushed into the groove 304. As the protective housing 3 covers the conductive component, the soft plug 701 is squeezed and deformed, fixing the protective housing 3 to the conductive platform plate 201. When it is necessary to make it easy to pull 30 out of the conductive platform plate 201, simply hold the finger-pinching block 702 on the soft buckle 7 and pull the soft block 701 outward a certain distance.

[0033] refer to Figures 3-6As shown, both the protective sleeve 6 and the protective shell 3 are made of non-conductive PVC injection molding material. During the use of the protective sleeve 6 and the protective shell 3, they isolate the conductive bolt 203 and the conductive platform protrusion 202 covered underneath. Even if other external lithium battery electrodes come into contact with the protective sleeve 6 and the protective shell 3, it will not cause a short circuit in the internal conductive bolt 203. The fixing block 4, the fixing shaft 401, and the connecting components are made of PVC and elastic rubber, while the soft buckle 7, the soft plug 701, and the finger-pinch block 702 are made of soft silicone. All of these are non-conductive materials, which can ensure that the conductive bolt 203 is isolated and protected during installation and transportation.

[0034] In practical use, before transporting the lithium-ion battery, a non-conductive protective component is installed. The soft clip 7 is inserted into the protective housing 3, and the soft plug 701 is pushed out. Then, the protective housing 3 is placed over the conductive platform plate 201, with the soft plug 701 engaging between the protective housing 3 and the conductive platform plate 201, thus fixing the protective housing 3 to the conductive platform plate 201 and completing the lateral limitation of the protective housing 3. The groove 304 inside the protective housing 3 is fitted onto the conductive platform plate 201, and the conductive platform protrusion 202 on the conductive platform plate 201 is inserted into the protective hole 302 in the groove 304. At this time, the conductive bolt 203 passes through the through hole 303 on the protective housing 3. Then, the protective sleeve 6 connected to the protective housing 3 is installed on the outside of the conductive bolt 203 via a threaded connection. The protective sleeve 6 is then tightened until it abuts against the upper surface of the protective housing 3, thus completing the longitudinal limitation of the protective housing 3. At this point, the protective housing 3 and the protective sleeve 6 are installed, and the conductive components and conductive bolts 203 are completely isolated and sealed inside. Due to their non-conductive material properties, the conductive components and conductive bolts 203 inside are protected from short circuits caused by collisions.

[0035] Compared with the prior art, the beneficial effects of this utility model are that a pluggable protective component is installed on the conductive platform of the electrode post, and a detachable protective sleeve for the protective bolt electrode post is installed on the protective component. The lithium battery electrode is protected during transportation and assembly by the protective component and the protective sleeve, avoiding short circuit damage caused by accidental electrode contact and improving transportation safety.
