The lower cover male connecting portion 122 and the lower cover female connecting portion 123 are located on one side of the lower cover 12; the plurality of lower cover protruding portions 124 are disposed on the opposite cover of the lower cover 12 and the second electrode 22 of the battery 2 One side surrounds the periphery of the lower cover through hole 121; the lower cover connecting hole 125 is located at the periphery of the lower cover 12.

When the user wants to use the battery to bond the ferrule 1, the upper cover 11 can be first placed on the first electrode 21 of the battery 2, and the first electrode 21 can be exposed to the upper cover through hole 111. then The lower cover 12 is placed over the second electrode 22 of the battery 2, and the second electrode 22 is exposed to the lower cover through hole 121. After the upper cover 11 and the lower cover 12 are installed at the two ends of the battery 2, the two ends of the connecting member 13 are respectively disposed on the upper cover connecting hole 115 and the lower cover connecting hole 125 to fix the upper cover 11 and the lower cover 12. On the battery 2.

It is worth mentioning that the upper cover 11 and the lower cover 12 can be formed by insert injection molding using an insulating material and a metal ring (116, 126), and the metal rings (116, 126) can be located at the upper cover connecting hole 115 and the lower cover. In the connecting hole 125, when both ends of the connecting member 13 are respectively passed through the upper cover connecting hole 115 and the lower cover connecting hole 125, the two ends of the connecting member 13 can be respectively engaged with the metal rings (116, 126). Alternatively, after the user combines the plurality of battery-bonding ferrules 1, the outer cover may be covered on one side of each of the battery-bonding ferrules 1, and the outer cover is locked to the upper cover 11 and the lower cover 12 by screws or other locking elements. The metal ring (116, 126) is fixed to each of the battery-bonding sleeves 1. In a preferred embodiment, the inner wall of the metal ring (116, 126) may be provided with a thread, and one end or both ends of the connecting member 13 may also be provided with a thread, when the two ends of the connecting member 13 are respectively When the upper cover connecting hole 115 and the lower cover connecting hole 125 are provided, the connecting member 13 can be attached to the upper cover connecting hole 115 and the lower cover connecting hole 125 by screwing. In another preferred embodiment, the connecting member 13 further includes a screw cap 131. After the connecting member 13 is disposed through the upper cover connecting hole 115 and the lower cover connecting hole 125, the user can lock the screw cap 131 to the connection. The upper end 11 and the lower cover 12 are fixed to the threads on both ends of the member 13. Alternatively, the connecting member 13 may further include a screw cap 131 and a gasket 132.

Upper cover 11 and lower cover 12.

It should be noted that the shape of the upper cover female connecting portion 113 corresponds to the periphery of the upper cover male connecting portion 112, so the battery combining sleeve 1 of the present invention can be combined with other battery cells. The sleeve 1 is connected to the upper cover 11 through the upper cover 11 and the upper cover 11 is inserted into the upper cover 11 or the upper cover 11 is inserted into the upper cover 11 by the upper cover 11 Connected to other upper covers 11. In addition, the shape of the lower cover female connecting portion 123 corresponds to the periphery of the lower cover male connecting portion 122. Therefore, the lower cover 12 of the battery combining ferrule 1 of the present invention can be inserted into the lower cover of the lower cover 12 through the lower cover male connecting portion 122. The female connecting portion 123 is connected to the other lower cover 12 by inserting the lower cover female connecting portion 123 into the lower cover 12 to cover the male connecting portion 122. Therefore, the battery-incorporated ferrule 1 of the present invention is mounted on the battery 2 and can be connected in series with other battery-connecting ferrules 1, whereby the plurality of batteries 2 can be combined into one battery array in a series connection manner.

Incidentally, each of the upper cover protrusions 114 of the upper cover 11 and the respective lower cover protrusions 124 of the lower cover 12 respectively have a predetermined interval. If the user assembles the plurality of battery-bonded sleeves 1, each upper cover The predetermined spacing between the respective upper cover projections 114 of the 11 may form an electrode serial connection region, and the predetermined spacing between the respective lower cover projections 124 of the respective lower cover 12 may also form an electrode serial connection region. Therefore, after the user uses the battery-bonding ferrule 1 of the present invention to serially connect the plurality of batteries 2 into a battery array, the user can provide an electrode serial-connecting plate on the electrode serial-connecting region to electrically connect the respective batteries 2.

In addition, the heights of the upper cover protrusions 114 and the respective lower cover protrusions 124 provided on one surface of the upper cover 11 and the lower cover 12 are respectively greater than the heights of the first electrode 21 and the second electrode 22, respectively, to avoid The electrode of the battery 2 assembled in the battery-bonding ferrule 1 causes leakage of the battery liquid due to collision of foreign matter.

Moreover, since the size of the upper cover through hole 111 is larger than the size of the first electrode 21, and the size of the lower cover through hole 121 is larger than the size of the second electrode 22, when the upper cover 11 is covered by the first electrode 21, the upper cover through hole 111 and An upper cover recessed portion 117 is formed between the first electrodes 21. When the user uses the battery 2 equipped with the battery-bonded ferrule 1, and the upper cover 11 When the battery 2 is located above the first electrode 21, the battery liquid can flow into the upper cover recess 117. Therefore, if the battery liquid leakage is small, the battery liquid is leaked. There is no danger of short-circuiting the battery 2 or eroding other devices placed next to the battery 2 for the time being. In addition, the function of forming the lower cover recess (not shown) between the lower cover through hole 121 and the second electrode 22 is the same as that of the upper cover recess 117, and therefore will not be described again.
