TECHNICAL FIELD

The present invention relates to a field of charging equipments, particularly to a clip of connecting wire for interconnecting charger and storage battery.

BACKGROUND

Clip of connecting wire is a device for connecting charger and storage battery, which can be used for charging storage batteries of cars, motors, motorcycles, or other household equipments. As shown in FIG. 1, a conventional method is solder terminal 130 to the clip 100, thus the clip 100 and the terminal 130 are integral. The terminal 130 is connected to the charger 200, and the clip 100 clasps on the storage battery 300 of the car, motor, or motorcycle. The conventional clip 100 results in that each charger 200 has one clip 100, and thus can only charge one type of matching storage battery 300. During working, the clip 100 clasps on the storage battery 300 and the charger 200 charges the storage battery 300.

Two ways to modify the conventional technology are follows: one is adding an adapter 400 between the charger 200 and the clip 100 of connecting wire (as shown in FIG. 1), i.e., a first adapter 400 is mounted on an outputting wire of the charger 200, and two or more conventional clips 100 are connected to a second adapter 400, the first adapter 400 and the second adapter 400 are matched with each other. In use, the first adapter 400 is connected to the second adapter 400, thus makes the charger 200 can be used to charge several types of storage batteries. The method of adding adapter 400 makes the charger 200 can connect several clips 100, and thus can charge several types of storage batteries, but this method needs to connect two or more conventional clips 100 to one adapter 400, adding adapter 400 and its manufacturing process cost. The other way is using ordinary screw 150 to assemble/disassemble the terminal 130 of the charger 200 to/from different types of clips 100 (as shown in FIG. 2), thus the charger 200 can be used to charge different types of storage batteries, which is more convenient for people's life. The method of using ordinary screw 150 to assemble or disassemble needs to form internal threads matching external threads of the ordinary screw 150 in hinged portions of different types of clips 100. In use, the internal threads in the hinged portion are excessive wear, and thus needs to replace the clip 100. Furthermore, using the ordinary screw 150 to assemble or disassemble the terminal 130 and clip 100 needs auxiliary tools (such as a screw 150 driver), which is inconvenient.

As shown in FIG. 4 and FIG. 5, the clip 100 includes a first metal arm 101 and a second metal arm 102 hinged to the first metal arm 101. A hinged portion of the first metal arm 101 and the second metal arm 102 is provided with an elastic member 103 cooperating with the first metal arm 101 and the second metal arm 102. The first metal arm 101, and the second metal arm 102 define a hinging hole 104. A sleeve 110 is provided in the hinging hole 104 and a fixing device 120 extending through the sleeve 110 for hinging the first metal arm 101, the second metal arm 102, and the elastic member 103. In detail, the sleeve 110 defines a smooth through hole 113 therein. The fixing device 120 includes a first connecting member 121 extending through the through hole 113, a disassembling rod formed on the first connecting member 121, a second connecting member 123 screwed on the first connecting member 121, and a disassembly member 124 provided on the first connecting member 121 or the second connecting member 123 for assembly or disassembly the first connecting member 121 and the second connecting member 123 rapidly. A movable terminal 130 is formed between the first connecting member 121 and the second terminal 130 for connecting the clip 100. The disassembly member 124 makes assembly or disassembly of the terminal 130 and the clip 100 need not auxiliary tools, which is convenient in use. In this embodiment, the disassembly member 124 includes two disassembly wings 1241 integrally formed with the second connecting member 123 to cooperatively form a butterfly nut.

The movable terminal 130 formed between the first connecting member 121 and the second terminal 130 for connecting the clip 100 makes the terminal 130 can be used to connect different types of clips 100, thereby charging different types of storage batteries, thus charging of the storage battery 300 is convenient, and needs not dedicated clip or terminal.

In this embodiment, the sleeve 110 is provided in the hinged hole between the first metal arm 101 and the second metal arm 102 with smooth through hole 113, and the fixing device 120 extends through the fixing device 120, which can avoid wear of internal of the clip 100 and frequently replacing of the clip 100 in the way of using ordinary screw 150 to assembly or disassembly the terminal 130 and the clip 100, which is in favor of saving costs of charging of the storage batteries of the household equipments.

As shown in FIG. 4 and FIG. 5, the elastic member 103 is mounted in the first metal arm 101 and the second metal arm 102 and surrounds the sleeve 110, cooperates with the first metal arm 101 and the second metal arm 102 to clasp the storage battery 300 of the car, motor, motorcycle, or other household equipment, and connects the charger 200 by the terminal 130, thereby charging the storage battery 300. As shown in FIG. 5, the elastic member 103 includes threaded part surrounding the sleeve 110 and two supporting parts extending from two ends of the threaded part to abut against the first metal arm 101 and the second metal arm 102, respectively. It can be understood that the elastic member 103 is made of metal.

It can be understood that, the connecting part 1211 extends through the through hole 113 of the sleeve 110, a part of the connecting part 1211 in the through hole 113 can be smooth or with threads. The end of the connecting part 1211 away from the locking part 1212 has external threads matching with the second connecting member 123, which makes the second connecting member 123 be screwed with the external threads of the connecting part 1211, and makes the terminal 130 be fixed on the first connecting member 121. An internal of the sleeve 110 is smooth, thus operation of extending of the connecting part 1211 through the sleeve 110 is simple and convenient, and damage and replacing of clip 100 for wear of the connecting part 1211 and the internal of the sleeve 110 is avoided.

In detail, the disassembly rod 122 includes an offsetting pivot 1221 fixed on the locking part 1212 and an arc-shaped handle 1222 integrally formed with the offsetting pivot 1221. When the handle 1222 is pull up, the terminal 130 and the clip 100 are unfix, and when the handle 1222 is press down, the terminal 130 and the clip 100 are fixed. A distance of a portion of the offsetting pivot 1221 between the locking part 1212 and the terminal 130 in the state of unfix is less than that of a potion of the offsetting pivot 1221 between the locking part 1212 and the terminal 130 in the fixed state, thus makes connection of terminal 130 and the clip 100 in the fixed state is tight. It can be understood that the locking part 1212 and the connecting part 1211 are integrally formed and are T-shaped, which is convenient for mounting the disassembly rod 122 quickly, as shown in FIG. 6.

An inner diameter of the first cylinder 1112 is larger than that of the second cylinder 1122. It can be understood that an internal hole of the second cylinder 1122 is the through hole 113. When the clip 100 is assembled, the first metal arm 101, the second metal arm 102 and the elastic member 103 are mounted the first cylinder 1112 of the first sleeve element 111, and then the second cylinder 1122 of the second sleeve element 112 is inserted in the first cylinder 1112. The first ring 1111, and the second ring 1121 are used to avoid falling off of the first metal arm 101, the second metal arm 102, and the elastic member 103.

During connecting the clip 100 and the terminal 130, as shown in FIG. 5, the connecting part 1211 of the first connecting member 121 extends through the gasket, the terminal 130, and the second sleeve element 112 and the first sleeve element 111 of the sleeve 110 in turn, and the second connecting member 123 is screwed with the external threads of the connecting part 1211, thereby fixing the terminal 130 onto the clip 100. During operation, as shown in FIG. 7, the clip 100 is fixed on the storage battery 300 of household equipment, and the handle 1222 of the disassembly rod 122 of the first connecting member 121 is pressed down, thus the terminal 130 is pressed on the storage battery 300 tightly to charge the storage battery 300.
