[0018] Tubular batteries are mostly 2V single cells. When in use, multiple single cells are connected in series through connecting strips to achieve higher voltage or larger capacity. The connecting strip is a commonly used structure in the prior art. The two ends of each connecting strip are respectively connected to the positive and negative terminals on the adjacent batteries. The top surface of the terminal has a threaded wiring hole. The connecting strip includes a connecting wire part and a connecting head located at both ends of the connecting wire part. The connecting head has a connecting piece, and the connecting piece is provided with a connecting hole. The connecting strip is fixed to the terminal by a bolt with one end passing through the connecting hole and cooperating with the threaded wiring hole.

[0019] The connecting strip is stretched, twisted, and deformed after installation. During subsequent use, it is easy to heat up, causing burns and breakage, which poses a safety hazard.

[0020] like Figure 1 and Figure 2As shown, a connecting bar protection device is used to protect the connecting bar used when the batteries are connected in series. The connecting bar protection device includes a female end 1 and a male end 2, and one female end 1 and one male end 2 are used in combination.

[0021] The female end 1 includes a collar portion 11 which is sleeved on the outside of the connection head at one end of the connection strip when in use, and a straight portion 12 which is sleeved on the outside of the connection line portion. The male end includes a collar portion which is sleeved on the outside of the connection head at the other end of the connection strip when in use, and a straight portion 22 which is sleeved on the outside of the connection line portion. The straight portions in the female end 1 and the male end 2 are only sleeved on the outside of the connection line portion on one side, and when combined, they are sleeved on the outside of the connection line portion of the entire connection strip.

[0022] A side where the collar portion of the female end 1 and the male end 2 are connected to the straight portion has an escape opening for escaping the connection area between the connection head and the connection line portion in the connection strip.

[0023] The female end 1 and the male end 2 are provided with a connection mechanism for connecting the female end 1 and the male end 2 on their respective straight portions. The structure of the connection mechanism specifically includes a clamping block 23 provided on the male end 2 and a clamping slot 13 provided on the female end 1, wherein the male end 2 is provided with a clamping block 23 at the end of the straight portion 22, and the female end 1 is provided with a plurality of clamping slots 13 cooperating with the clamping block 23 at intervals on the straight portion 12. The clamping block 23 is formed by the male end 2 protruding to the side on the end surface of the straight portion 22, and the clamping slot 13 is opened on the side wall of the straight portion 12 of the female end 1.

[0024] In a preferred embodiment, a plurality of slots 13 are provided at intervals on the side wall of each side of the straight portion 12 of the female end 1, and the slots 13 are interconnected to avoid the side wall of the straight portion 22 of the male end 2. Thus, by matching the block 23 on the male end 2 with different slots 13 on the female end 1, the total length of the straight portion 12 of the female end 1 and the straight portion 22 of the male end 2 after matching can be adjusted, so that it can be applied to connecting strips of different specifications, increasing the versatility of the connecting strip protection device of the present application.

[0025] In order to facilitate taking and placing, a handle 14 is provided on the female end 1, and a handle 24 is also provided on the male end 2. Preferably, the handle is provided on the collar portion of the female end 1 or the male end 2, and extends outward.

[0026] When the connecting strip protection device of the present invention is used, firstly, the two ends of the connecting strip are placed on the positive and negative terminals of two adjacent batteries to be connected; then, the ring portion 11 of the female end 1 is inserted into one end of the connecting strip of one of the single cells, and the ring portion 11 is sleeved on the outside of the connecting head at one end of the connecting strip; according to the spacing between the positive and negative terminals to be connected, that is, the length of the connecting strip, the ring portion 21 of the male end 2 is inserted into the outside of the connecting head at the other end of the connecting strip, and at the same time, the clamping block 23 is engaged with the corresponding clamping groove 13 to lock the connection, and the connecting line portion of the connecting strip is protected by the cooperation of the straight portion 12 and the straight portion 22; after the connecting strip is completely inserted and adjusted into place and protected, by pressing the handle or fixing the handle with other tools to prevent the connecting strip protection device of the present application from moving during operation, the screws for installing and fixing the connecting strip can be tightened.
