[0002] The connection terminal of the lead-acid battery of the golf cart is a combination of lead parts embedded with bolts. When the battery is connected in series for charging, there are generally two connection methods. The first connection method is to use a connection nose and fasten it with a nut; the second connection method is to use a cast lead part and a terminal lead part. Both connection methods will cause abrasion on the surface of the battery terminal when connected, leaving scratches on the terminal surface. When users buy batteries, they mistakenly think that the battery has been used or are dissatisfied with the appearance of the battery. Therefore, it is necessary to invent a new charging connection line for formation, which will not cause abrasion and scratches on the surface of the battery terminal when connected to the battery.

[0017] The utility model is further described below in conjunction with the accompanying drawings.
[0018] like Figure 1 As shown, an embodiment of a charging connection line for forming a lead-acid battery of the utility model is composed of a connection contact 2, a charging line 3 and a butterfly nut 4, and is used for connecting with a golf cart battery terminal 1 during formation.
[0019] Among them, the battery terminal 1 is composed of lead parts embedded with bolts. When it is produced and charged in the factory, it is used for series wire connection. When used by the user, it is connected to the vehicle wire.
[0020] The charging cable 3 is a hard charging cable.
[0021] The connecting contact 2 is cylindrical and made of copper. The connecting contact 2 is fixedly connected to the end of the charging line 3. When forming a charging connection, it contacts the top surface of the bolt of the battery terminal 1 to conduct current.
[0022] The butterfly nut 4 is made of stainless steel. The inner thread of the cavity of the butterfly nut 4 cooperates with the bolt of the battery terminal 1. The inner cavity depth of the butterfly nut 4 is less than the height of the bolt of the battery terminal 1, and the height of the bolt is the height of the exposed part of the bolt. The top of the butterfly nut 4 is provided with an end face, and the center of the end face is provided with an end face through hole, and the charging line 3 passes through the end face through hole of the end face of the butterfly nut 4. The diameter of the connecting contact 2 is smaller than the diameter of the inner cavity of the butterfly nut 4, and larger than the diameter of the end face through hole of the butterfly nut 4, and the connecting contact 2 can be located in the cavity of the butterfly nut 4. The butterfly nut 4 passes through the charging line connected to the wiring contact, and is tightened with the bolt on the battery terminal 1 to form a set of stable series connection structures.
[0023] When the lead-acid battery of the golf cart is connected in series for charging, the port (or connecting contact) of the inner cavity of the butterfly nut 4 is aligned with the bolt of the battery terminal 1 of the golf cart, so that the connecting contact 2 enters the cavity of the butterfly nut 4, and the butterfly nut 4 is rotated to tighten it with the bolt.
