Wiring terminal for measuring and current continuing

Abstract

The invention discloses a wiring terminal for measuring and current continuing. The wiring terminal for measuring and current continuing comprises two symmetrical gaskets, a connecting sheet for conducting electricity between the two gaskets, and a control piece for controlling the connecting sheet to move upwards or downwards, wherein the two gaskets are arranged in parallel left and right and are not in contact with each other, each gasket is formed by a diversion copper bar, a front end part vertically arranged at the front end of the diversion copper bar and a cold pressing wiring port arranged at the rear end of the diversion copper bar, the front end parts are in a twisted-flower rush herb shape, the two front end parts symmetrically form sleeving holes with openings, the sleeving holes are adaptive to the screws on a pole column, the ends of wires of a collection device is extended into the cold pressing wiring port and are crimped together, and the connecting sheet is located at the upper portion of the diversion copper bar. The measurement points are fixed, the two wiring terminals are moved upwards on the connecting sheet to allow the two wiring terminals to be switched to a four wire mode when breaking away from the two diversion copper bars, and are moved downwards on the connecting sheet to allow the two wiring terminals to be switched to a two wire mode when being in contact with the two diversion copper bars so as to ensure that the collection points of the four wire mode to be the same point and bear a large current for long time.

Description

technical field [0001] The invention relates to an auxiliary accessory for connecting the positive pole and the negative pole of a collection device and a battery, in particular to a connection terminal for measurement and freewheeling. Background technique [0002] Batteries have been widely used in DC backup power supply. In recent years, there are more and more products and equipment for online monitoring and protection of battery packs. All of these products and equipment, without exception, need to connect the positive and negative poles of the battery to the collection equipment. [0003] The conventional wiring methods used between the collection device and the positive and negative electrodes of the battery are as follows: 1) Metal clips are used. The end of the metal clip is welded or crimped to the wire of the collection device, and the clip part of the metal clip clamps the battery. Screws on the pole of the positive or negative pole; 2) Metal clips are used, the...

Problems solved by technology

The calculation of internal resistance requires very accurate measurement of the voltage and discharge current during short-term discharge. A difference of a few millivolts can lead to a large difference in the calculation results of internal resistance, so accurate measurement is required. The short-term discharge time collected through the above wiring methods The accuracy of the voltage and discharge current is not ideal due to the existence of different measurement points
