Description

Technical Field

[0001] The utility model belongs to the technical field of lithium battery connectors, in particular to a detachable lithium battery connector. Background Art

[0002] Lithium battery is a lithium-ion battery that uses lithium iron phosphate as the positive electrode material and carbon as the negative electrode material. The rated voltage of the single cell is 3.2V and the charging cut-off voltage is 3.6V~3.65V. Lithium battery has the advantages of high operating voltage, high energy density, long cycle life, good safety performance, low self-discharge rate and no memory effect.

[0003] Most of the existing lithium battery connectors are generally fixed by welding, which is not convenient for installation and removal from the cover plate, which is very inconvenient when connecting with the connecting wire. When disconnecting the lithium battery from the connecting wire, a wrench or other disassembly tools are required, which makes the disconnection process very troublesome, not only time-consuming and labor-intensive, but also may damage the connecting wire of the lithium battery, resulting in increased installation and disassembly time for workers. In view of the problems and shortcomings of the existing lithium battery connectors, we propose a new type of detachable lithium battery connector. Utility Model Content

[0004] The utility model aims to provide a detachable lithium battery connector, which solves the problem that the existing detachable lithium battery connector is fixed by welding during use, which is inconvenient to install and remove from the cover plate, and is very inconvenient when connected with a connecting wire. When the lithium battery is disconnected from the connecting wire, a disassembly tool such as a wrench is required, which makes the disconnection process very troublesome, not only time-consuming and labor-intensive, but also may damage the connecting wire of the lithium battery, resulting in increased installation and disassembly time for workers.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses a detachable lithium battery connector, comprising a lithium battery case, wherein one side of the upper surface of the lithium battery case is fixedly connected with a battery post head, a ferrule is fixedly connected with an outer surface of the battery post head, both sides of the ferrule are fixedly connected with limiting clamping teeth A, both ends of the ferrule are provided with grooves A, the top of the battery post head is fixedly connected with a circular ring, a groove B is provided below the circular ring, the ferrule is matched with the battery post head, a connecting sleeve is sleeved on the outer surface of the battery post head, limiting clamping teeth B are provided on both sides of the interior of the connecting sleeve, the limiting clamping teeth B are matched with the limiting clamping teeth A, and the limiting clamping teeth A on both sides of the ferrule are matched with the limiting clamping teeth B on both sides of the interior of the connecting sleeve, so that when the battery post head is inserted, the limiting clamping teeth A and the limiting clamping teeth B are tightly matched, and the battery post head is firmly fixed in the connecting sleeve.

[0007] Furthermore, a power line connector is fixedly connected to the top of the inner wall of the connecting sleeve, and the power line connector is adapted to the top of the battery pile head.

Through the setting of the buffer spring and the limiting block, after the battery pile head enters the connecting sleeve, the limiting block is adapted to the groove B, and the battery pile head is further limited and fixed.

[0009] Furthermore, a tooth block A is fixedly connected to the lower surface of the limit block, a gear is meshed on the lower surface of the tooth block A, and a gear is meshed on the lower surface of the gear. A tooth block B is meshed on the lower surface of the gear.

[0010] Furthermore, the number of the gears is several and they are symmetrically distributed on both sides of the inner wall of the connecting sleeve, and the latching tooth block B is matched with the latching tooth block A through the gears.

[0011] Furthermore, the two ends of the latch block B are arc-shaped structures, one end of the latch block B is movably connected with a buffer spring sheet, and the other end of the latch block B is adapted to the groove A. Through the setting of the circular ring on the top of the battery pile head, when the battery pile head moves downward, the circular ring is pressed against the limit block, and through the adaptation of the latch block B, the gear and the latch block A, the latch block B moves to one side of the battery pile head and adapts to the groove A. Under the action of the thrust, the matching limit tooth A and the limit tooth B are separated, and the sleeve and the battery pile head are separated from the connecting sleeve to complete the disassembly work.

[0012] The utility model has the following beneficial effects:

[0013] 1. Through the arrangement of structures such as the battery post head, the clamping sleeve, the limit teeth A, the limit teeth B, the groove A, the groove B, and the connecting sleeve, when the battery post head is inserted, the limit teeth A on both sides of the clamping sleeve are matched with the limit teeth B on both sides of the inside of the connecting sleeve, and the limit blocks on both sides of the middle part of the connecting sleeve are matched with the groove B, so that the battery post head is firmly fixed in the connecting sleeve, which solves the problem that the battery post head is fixed by welding in the prior art, which is inconvenient to install and disassemble it from the cover plate, thereby causing great inconvenience when connecting with the connecting line.

[0014] 2. Through the arrangement of the buffer spring, the limit block, the latch tooth block A, the gear, the latch tooth block B and the ring, it is achieved that when the battery pile head moves downward, the ring is pressed against the limit block, and the latch tooth block B is matched with the latch tooth block A through the gear, so that the latch tooth block B moves to one side of the battery pile head and matches with the groove A, and the matching limit teeth A and limit teeth B are separated, so that the clamping sleeve and the battery pile head are separated from the connecting sleeve, which solves the problem in the prior art that when disconnecting the lithium battery from the connecting wire, a disassembly tool such as a wrench is needed to perform the disconnection, which makes the disconnection process very troublesome, not only time-consuming and labor-intensive, but also may damage the connecting wire of the lithium battery, resulting in increased installation and disassembly time for workers.
