Description
Technical field
The utility model relates to a kind of battery clamp of battery testing technical field, specifically, relates to a kind of four-wire method poly-lithium battery anchor clamps.
Background technology
Usually the poly-lithium battery testing apparatus adopts four-wire method battery testing anchor clamps, and anchor clamps are made up of train wheel bridge and lower plate, and last lower plate respectively is equipped with a slice copper sheet, is respectively the voltage terminal and the current terminal of anchor clamps.Wherein train wheel bridge is movable, and rotates up and down around axis, and lower plate is fixed, and between the last lower plate spring is housed, and movable train wheel bridge one end is by spring jack-up, and the other end is used to clamp battery pole ear.Because the positive and negative lug of poly-lithium battery all is narrower foil, and the spacing of the positive and negative lug of the battery of different model is different, in order to adapt to the battery of multiple model, the shape that all adopts broad of train wheel bridge and lower plate, but the following problem that produces is when clamping battery pole ear, there be the not parallel of clamping surface, and make that going up the folder copper sheet occurs directly contacting with following folder copper sheet easily, make the direct short circuit of current terminal and voltage terminal, make voltage terminal also flow through electric current, cause four-wire method to become two collimation method anchor clamps, finally cause the test data of battery inaccurate.
The utility model content
At above deficiency, the utility model provides the four-wire method poly-lithium battery anchor clamps of a kind of accurately measuring current and magnitude of voltage, it comprises clip, the dop position of described clip is respectively equipped with last contact and the following contact that is used to clamp battery pole ear, the described surface of contact of going up contact or following contact is provided with insulating trip, and described insulating trip partly covers described contact or the following contact gone up.
The described contact of going up is a copper sheet with following contact.
Described clip comprises train wheel bridge and the lower plate that cooperatively interacts, and the spring that described train wheel bridge and lower plate are installed, the surface of contact of described train wheel bridge and lower plate correspondence is respectively equipped with contact and following contact, the described contact of going up comprises separate outer contact and the interior contact of going up gone up, described contact down comprises and described outer contact and interior contact corresponding respectively separate outer contact down and the interior contact down gone up gone up, described insulating trip part respectively covers described outer contact and the interior contact of going up gone up, and perhaps described insulating trip part respectively covers described outer contact down and interior contact down.
Described insulating trip is gone up contact respectively outside and is formed with first contact region and second contact region that is used to contact battery pole ear with interior going up on the contact, and perhaps described insulating trip descends contact to be formed with the 3rd contact region and the 4th contact region that is used to contact battery pole ear on the contact down with interior respectively outside.
Described insulating trip is the insulation gummed paper.
The beneficial effects of the utility model are: 1) insulating trip of Nian Tieing can not influence the clamp battery.The insulating trip that sticks on contact (or following contact) covers fully goes up contact, only cover the very little two parts in inside and outside both sides, do not cover the insulating trip part in the middle of the copper sheet and can touch battery pole ear, insulating trip is very thin in addition, the lug of battery is thicker than insulating trip, so insulating trip can not influence the clamp battery; 2) can effectively cut off contacting of folder copper sheet and following folder copper sheet, realize real four-wire method measurement.This structure makes anchor clamps effectively cut off the contact of copper sheet up and down again when clamping lug, has guaranteed not direct short circuit of anchor clamps current terminal and voltage terminal, realizes real four-wire method measurement, has guaranteed that also the test data of battery is more accurate.
