Description

Durable crocodile clip

Technical Field

The utility model relates to the technical field of electrified test pieces, in particular to a durable crocodile clip.

Background

The existing crocodile clip in the current market is easy to break copper wires at the junction. During the motor test, the crocodile clip is still good, but the test wire is broken. Because the test process data needs to be tested well again, great difficulty is brought to the test work. In particular, in motor manufacturing enterprises, one production line is required to produce five or six hundred motors each day. The production beat is relatively fast, and the testers can not timely replace crocodile clips in the test process. Thus, the available test lines are gradually reduced, and only the waiting electric repair staff are used for replacement, which can affect the production rhythm. Sometimes, a plurality of stations are damaged at the same time a day, so that the testing efficiency is seriously affected. A motor production line is 30 test lines in total, and 50 to 70 test wires are replaced in one month after workshop statistics. This not only increases the production costs, but also severely affects the production schedule.

Common crocodile clips in the market are made of copper and plated with copper, and the common crocodile clips are provided with an insulating sleeve and a non-insulating sleeve in the aspect of safety. In either case, the wire is stripped of its insulating sheath and then the copper wire is plugged into the mounting hole of the alligator clip and the alligator clip hole is clamped firmly by the nose clip. After a period of use, the crocodile clip is broken by the multiple strands of copper wires in the test wire. Currently, the market also has a clamp made of plastic, and a copper block is fixed at the front end of the clamp as a conductor. In this way, the plastic is easy to break during collision and extrusion, and the clamp body cannot be made smaller. In summary, the use is inconvenient, and therefore, the utility model provides a durable crocodile clip.
