The invention relates to a storage battery chuck, which is used for connecting a live wire, comprising a sleeve, a first opening and a second opening are opened at both ends of the sleeve respectively, and the live wire is connected to the sleeve; a button, the button is arranged coaxially with the sleeve, and the button snapped into the sleeve and pass through the first opening; a plurality of clips, the plurality of clips are circumferentially arranged in the sleeve, and the button pushes against the plurality of clips to make the plurality of clips move along the radial direction of the second opening expansion. The technical solution provided by this application replaces the point contact method of the traditional chuck through the surface contact between multiple clips and poles, increases the contact area, and makes the contact resistance lower and more reliable; the use of button switches saves effort , and meet the requirements of ergonomics and mechanics; instead of the torsion spring in the middle of the traditional chuck, the lever principle of the clip is used to make the clamping more reliable; the external insulating shell replaces the traditional crocodile chuck with a large amount of metal materials exposed to the outside The situation, which greatly reduces the risk of accidentally touching the charged body during operation.
Description
technical field [0001] The invention relates to the field of electric power engineering, in particular to a storage battery clamp. Background technique [0002] The traditional battery chuck is an alligator chuck, and most of them are stamped from copper sheets. A tension spring is used in the middle to provide the holding force, and the live wire is connected to the tail of the alligator chuck. Since the copper chuck relies on the teeth of the crocodile chuck when clamping the battery pole, the clamping method of this method is mostly a point contact method, and the contact resistance is large. When measuring the internal resistance, the contact resistance is enough to affect the measurement results. Accuracy, and when passing a large current, due to the large contact resistance, the chuck is very easy to heat up or even burn. The traditional collet provides clamping force through the spring set in the middle. According to the lever theorem, every increase of 1N pressure o...
