[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Depend on Figures 1 to 5The invention provides a method of providing a connecting wire body 50, an insulating cylinder 10 sleeved on the connecting wire body 50, and connecting heads 20 placed at both ends of the connecting wire body 50. The connecting wire body 50 is used to carry the current of charging and discharging of the battery, and the connecting head 20 is used to connect the pole of the battery. The connecting head 20 is cast by lead liquid. During use, it is considered that traditional metal clips are prone to sparks when clamping the pole of the battery, resulting in a shorter service life. Therefore, in the production of the connecting head 20, the lead liquid commonly used in battery production is combined for integral casting. Compared with metal clips, it has higher charging efficiency. The connecting head 20 is also not easy to generate sparks when clamping the pole, and the service life is greatly increased. Both ends of the insulating cylinder 10 are coaxially fixed with a connecting cylinder 30, and the connecting head 20 is placed below the connecting cylinder 30. The connecting cylinder 30 includes a fixing cylinder 31 and a connecting plate 32. The fixing cylinder 31 is coaxially fixed to the insulating cylinder 10. The connecting plate 32 is fixed to the bottom of the fixing cylinder 31, and a connecting groove 321 is provided on a side of the connecting plate 32 away from the fixing cylinder 31. A plug 21 is coaxially fixed to the top of the connecting head 20, and the plug 21 is plugged into the inside of the connecting groove 321. Considering that the connecting head 20 also needs regular maintenance and replacement during use, the traditional fixing method is not only inconvenient to replace, but also easy to cause damage to the connecting line body 50 during the disassembly process. Through the connection cylinder 30, the plug 21 and the connecting groove 321, etc., it is only necessary to plug the plug 21 at the top of the connecting head 20 into the inside of the connecting groove 321 to achieve quick installation. It should be noted that the plug 21 and the connecting groove 321 are interference fit, and the two connecting heads 20 are both provided with a cavity 202 on one side close to the plug 21, and the other side of the two connecting heads 20 is provided with a polygonal groove 201, and the two ends of the connecting line body 50 are respectively located in the inside of the two cavities 202;

[0028] Taking into account that the connector 20 and the connecting cylinder 30 are mainly connected in the form of plug-in, there is a risk of falling off during use, a plurality of limiting cylinders 60 are evenly distributed on the circumference of the bottom outer edge of the connecting plate 32, and a limiting groove is provided at the bottom of the limiting cylinder 60. A slider 61 is slidably connected between the limiting cylinder 60 and the inside of the limiting groove, and a limiting plate 62 is fixed to the bottom of the slider 61. The slider 61 is connected to the limiting cylinder 60 through a spring. Through the settings of the slider 61, the limiting plate 62 and the limiting cylinder 60, when the latch 21 is plugged into the inside of the connecting groove 321, the limiting plate 62 contacts with one side of the latch 21 under the action of the spring, and the latch 21 is pressed. Axial limiting is performed to prevent the connecting head 20 and the connecting cylinder 30 from falling off. A plurality of through holes are opened on the connecting plate 32, which penetrate into the interior of the limiting cylinder 60. Pull ropes 63 are arranged inside the plurality of through holes. A slide cylinder 40 is coaxially arranged on the top of the connecting plate 32. The pull rope 63 is located at one end of the limiting cylinder 60 and is fixedly connected to the slider 61, and the other end of the pull rope 63 is fixedly connected to the slide cylinder 40. Through the through holes, the pull rope 63 and the slide cylinder 40, the slide cylinder 40 is pulled upward to drive the pull rope 63 to pull the slider 61 to move, thereby realizing the synchronous movement of the plurality of limit plates 62, and quickly releasing the limit of the plurality of limit plates 62 and the latch 21, saving time and effort.

[0029] In order to prevent workers from getting electric shock when operating the connecting tube 30 , the connecting tube 30 is made of rubber insulating material.

[0030] refer to Figure 4 and Figure 6 As shown, considering that when the plug 21 is inserted into the connecting groove 321, the limit plate 62 may interfere with the plug 21, thereby prolonging the time for the connector 20 to be inserted into the connecting tube 30, the limit plate 62 includes a horizontal portion 621 and an inclined portion 622, and the horizontal portion 621 contacts the connecting plate 32. A conical surface corresponding to the inclined portion 622 is provided on the plug 21. Through the horizontal portion 621, the inclined portion 622 and the conical surface on the plug 21, when the plug 21 is inserted into the connecting groove 321, the conical surface on the plug 21 contacts the inclined portion 622. As the plug 21 continuously approaches the connecting groove 321, a plurality of limit plates 62 are squeezed and move outward accordingly, thereby improving the installation time of the connector 20 and the connecting tube 30. The material of the limit plate 62 is rubber or plastic.

[0031] refer to Figure 1 As shown, a handle 41 is provided on the slide 40 . The slide 40 is made of rubber or plastic. The handle 41 is provided to facilitate the operation of the slide 40 by the staff.

[0032] Considering that good sliding properties are required between the limiting cylinder 60 and the sliding block 61 , the limiting cylinder 60 and the sliding block 61 are made of metal.

[0033] When the utility model is used:

[0034] First, the plug 21 at the top of the connector 20 is inserted into the connection slot 321. During the insertion process, the conical surface of the plug 21 contacts the inclined surface 622. As the plug 21 approaches the connection slot 321, the plurality of limit plates 62 are squeezed and move outwards accordingly until the plug 21 is completely inserted into the connection slot 321. At this time, the limit plates 62 are reset under the action of the spring, and the horizontal surface 621 contacts the plug 21.

[0035] Then, when the connectors 20 at both ends of the connecting wire body 50 are all installed, the worker inserts one of the connectors 20 into the corresponding battery pole and the other into the power supply element by holding the connecting cylinder 30 or the sliding cylinder 40;

[0036] Finally, when performing regular maintenance or replacement of the connector 20, the worker only needs to hold the handle 41 and move the slide 40 to one side. At this time, the pull rope 63 drives the slider 61 and the limit plate 62 to move to one side, releasing the axial limit of the limit plate 62 on the pin 21, and then the connector 20 can be unplugged.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
