Description

Technical Field

[0001] This utility model relates to the field of battery connector technology, and in particular to a corrosion-resistant battery connector. Background Technology

[0002] Battery connectors, also known as battery connecting pieces, generally serve as the connection points between the positive and negative electrodes of the battery and the battery holder or battery box. In new energy batteries, connecting pieces are responsible for conducting current and ensuring effective connection and power transmission between battery cells.

[0003] Patent publication number CN210607432U discloses a battery connector, including a connecting body with connecting ends at both ends. Each connecting end has a slot, and the end of the connecting body is inserted into the slot. A connecting plate is mounted on the end of the connecting end furthest from the connecting body, and the connecting plate has a connecting hole. An installation groove is formed on the inner wall of the slot along the length of the connecting body. A rack is provided on the outer wall of the end of the connecting body along its length, and the rack meshes with a gear located within the installation groove. A rotating rod is coaxially fixedly connected to the gear, and the rotating rod rotatably passes through the outer wall of the connecting end. A locking nut is threaded onto the rotating rod and located on the outside of the connecting end. This connector allows for flexible adjustment of its length, facilitating the connection of battery terminals at different distances.

[0004] The above device enables flexible adjustment of the connector length to match battery terminals of different lengths. However, when adjusting the length, it simply uses the method of controlling the gear to rotate and drive the rack to move to achieve the adjustment purpose. Moreover, it does not have a limit function after adjustment. This makes it easy for the overall length of the connector to wobble and change under the action of external force after adjustment, resulting in poor stability. Therefore, a corrosion-resistant battery connector is proposed to solve the above problems. Utility Model Content

[0033] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 The present invention will be described in further detail below.

[0034] This utility model discloses a corrosion-resistant battery connector. (Refer to...) Figures 1-7 It includes a first connecting plate 1 and a second connecting plate 2. The first connecting plate 1 has two plug-in plates 3 integrally formed at one end. The second connecting plate 2 has two plug-in slots 4. The plug-in plates 3 extend into the plug-in slots 4 and match the plug-in slots 4. A protective mechanism 9 is provided on the outside of the first connecting plate 1.

[0035] The second connecting plate 2 has movable grooves 5 on both the front and rear sides. A limiting block 6 is provided inside the movable groove 5. The limiting block 6 is in contact with the inner side of the movable groove 5. A positioning bolt 7 is provided on one side of the limiting block 6. The positioning bolt 7 passes through the limiting block 6. A positioning hole 8 is provided on the plug-in plate 3.

[0036] The positioning bolt 7 extends into the positioning hole 8 and is connected to the positioning hole 8 by threads. After the plug plate 3 on the first connecting plate 1 is inserted into the plug groove 4 in the second connecting plate 2, the first connecting plate 1 and the second connecting plate 2 form a complete connecting device. When connecting battery ends of different lengths, the distance between the first connecting plate 1 and the second connecting plate 2 can be directly adjusted. After adjustment, the positioning bolt 7 is screwed in to make the limiting block 6 fit tightly against the inner side of the movable groove 5, thereby fixing the plug plate 3 and making the adjusted first connecting plate 1 and the second connecting plate 2 have high stability.

[0037] Assembly holes 10 are provided on both the first connecting plate 1 and the second connecting plate 2. The two insertion slots 4 are respectively connected to the two movable slots 5. The assembly holes 10 are used for assembly on the battery end.

[0038] The protective mechanism 9 includes a first protective plate 91 and a second protective plate 92. The first protective plate 91 is disposed on the outside of the first connecting plate 1 and matches the first connecting plate 1. The top wall of the first protective plate 91 extends into the inside of the second protective plate 92 and contacts the inside of the second protective plate 92. The second protective plate 92 is disposed on the outside of the second connecting plate 2 and matches the second connecting plate 2. An auxiliary plate 93 is fixedly connected to both the first connecting plate 1 and the second connecting plate 2. The first protective plate 91 and the second protective plate 92 have external protective functions.

[0039] Limiting holes 94 are provided on one side wall of the first protective plate 91 and the second protective plate 92. Two auxiliary plates 93 pass through the two limiting holes 94 respectively. The auxiliary plates 93 match the limiting holes 94. After the auxiliary plates 93 pass through the limiting holes 94, they provide initial limiting for the first protective plate 91 and the second protective plate 92. A locking block 95 is slidably connected inside the auxiliary plate 93. The locking block 95 extends out of the auxiliary plate 93. The two locking blocks 95 are respectively attached to the outer side of the first protective plate 91 and the second protective plate 92. A spring 96 is fixedly connected inside the auxiliary plate 93. The spring 96 is fixedly connected to one side of the locking block 95. The spring 96 exerts an elastic force on the locking block 95.

[0040] Both the first protective plate 91 and the second protective plate 92 have through grooves 97. Both the first protective plate 91 and the second protective plate 92 are fixedly connected to annular plates 98. The through grooves 97 match the mounting holes 10 to facilitate installation on the battery end. An end cap 99 is provided on the top of the annular plate 98. The annular plate 98 extends into the end cap 99 and fits against the inner side of the end cap 99. The end cap 99 seals the top of the annular plate 98.

[0041] In actual operation, when this device is used, the plug plate 3 on the first connecting plate 1 is inserted into the plug slot 4 in the second connecting plate 2, thereby causing the first connecting plate 1 and the second connecting plate 2 to form a complete connecting device. When connecting battery ends of different lengths, the distance between the first connecting plate 1 and the second connecting plate 2 can be directly adjusted. After adjustment, the limiting block 6 is placed inside the movable slot 5, and the center position of the limiting block 6 is aligned with the positioning hole 8. Then, the positioning bolt 7 is passed through the limiting block 6 and screwed into the positioning hole 8. After the positioning bolt 7 is tightened, the limiting block 6 is tightly attached to the inner side of the movable slot 5, thereby fixing the plug plate 3 and making the adjusted first connecting plate 1 and the second connecting plate 2 have high stability.

[0042] By inserting the plug plate 3 into the plug slot 4, the overall length can be flexibly adjusted. Alternatively, the plug plate 3 can be pulled out of the plug slot 4 to separate the two, so that they can be replaced when a single part is damaged, thus avoiding the situation where the traditional integrated design device requires the whole device to be replaced, which is costly.

[0043] Finally, during use, the first protective plate 91 and the second protective plate 92 set on the outside of the first connecting plate 1 and the second connecting plate 2 can effectively protect the outer surfaces of the first connecting plate 1 and the second connecting plate 2, preventing external corrosive substances from eroding the first connecting plate 1 and the second connecting plate 2 and causing damage, effectively improving the overall corrosion resistance of the device. At the same time, the first protective plate 91 and the second protective plate 92 do not seal the inside and bottom of the first connecting plate 1 and the second connecting plate 2, thereby ensuring full contact between the first connecting plate 1 and the second connecting plate 2 and the battery connection end, ensuring conductivity.

[0044] When installing the first protective plate 91 and the second protective plate 92, the first protective plate 91 is inserted from one side of the first connecting plate 1, and the second protective plate 92 is inserted from one side of the second connecting plate 2. When the auxiliary plate 93 passes through the limiting hole 94, the inclined surface on the locking block 95 is squeezed and enters the interior of the auxiliary plate 93. When the first protective plate 91 and the second protective plate 92 are respectively attached to the outer side of the first connecting plate 1 and the second connecting plate 2, the locking block 95 just passes through the limiting hole 94. At this time, under the elastic force of the spring 96, the locking block 95 is pushed out of the outer side of the auxiliary plate 93. At this time, the locking block 95 clamps and limits the first protective plate 91 and the second protective plate 92 to keep them stably installed.

[0045] After the device is connected and installed on the battery, the end cap 99 is pressed and closed on the annular plate 98. The end cap 99 can provide protection for the top of the through groove 97, which can further prevent corrosive substances from causing pollution and corrosion to the battery connection. After the top wall of the first protective plate 91 extends to the inside of the top wall of the second protective plate 92, it can also slide on the inside of the top wall of the second protective plate 92, thereby changing the overall protection length and adapting to the adjusted length of the first connecting plate 1 and the second connecting plate 2.

[0046] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
