The device for testing the discharge performance of the primary battery is widely applied to primary battery production enterprises and primary battery product quality inspection and detection mechanisms and is used for detecting the discharge time of the primary battery. In order to ensure that the detection result of the equipment is accurate and reliable, the current indicating value of the equipment test channel needs to be traced regularly.
When tracing the current parameters of the device for testing the discharge performance of the primary battery, the primary battery and the current standard source are generally connected in series and then connected in a test channel of the device. After the test channel operates, the channel detects the voltage output current provided by the battery, and the source tracing is carried out by comparing the current indicating value of the equipment with the standard value of the current standard source.
At present, when current tracing is carried out on a test channel of the equipment, at least 2 detection personnel are usually configured, 1 detection personnel use hands to realize connection and fixation of a positive terminal of the test channel, a positive terminal of a battery, a negative terminal of the battery and a positive terminal of a current standard source, and the other 1 detection personnel use hands to realize connection and fixation of the positive terminal of the battery, the negative terminal of the current standard source and a negative terminal of the test channel and read a current value of the current standard source.
The positive terminal and the negative terminal of the current standard source mainly have universal shapes such as a probe type, a crocodile clip type, a wire nose type and the like. On one hand, because the positive electrode and the negative electrode of the primary battery are generally planar, the series connection of the battery and the current standard source is difficult; on the other hand, because the size of the test channel is similar to the conventional size of the original battery, the battery and the current standard source are difficult to be connected in the test channel after being connected in series.
The connection process of the test channel, the battery and the current standard source is complicated when the hand is used for realizing the connection, because too many hand fixing links easily cause unstable connection to form open circuit, the operation is stopped after the voltage of the battery cannot be detected by the channel, and the test program needs to be restarted. Therefore, the working efficiency of the current tracing process of the test channel of the equipment is lower.
