How to use the pogo pin quick connector?
A quick connector is a tool used for connection and plugging in air tightness tests. To improve production efficiency, quick connectors with reliable quality and complete supporting equipment must be selected. Therefore, when choosing a quick connector, factors such as the type of working nozzle to be connected, test fluid, test pressure, test temperature, and test environment need to be considered. Therefore, it is necessary to understand the functional characteristics of the required quick connectors to ensure high matching of the equipment.
For example, the connector of the new energy battery mainly tests these two aspects, one is the sealing performance test, and the other is the comprehensive test of the battery performance. When doing the sealing test of the battery pack casing, various interfaces on the casing must be sealed, such as explosion-proof valve interface, cable interface, high-voltage interface, etc.
The design method of quick connectors is much more complicated than ordinary connectors. Only the current load, life cycle durability, external relay strength, safety performance standards, and other factors of the quick connector need to be carefully considered. So pay more attention to the choice of quick connectors, there are many connection methods. In order to ensure its work efficiency, safety, and reliability, we must understand the wiring methods of some quick connectors.
Twisted connection of quick connectors
Twisting means that the cores to be connected are directly and tightly twisted together. Generally, copper wires are mostly connected by stranded, and single-strand copper wires are directly connected.
①When connecting small-section single-strand copper wires, first cross the core wires of the two wires in an X-shape, then twist them 2 to 3 times, then straighten the two wires, and then place each wire on the other core wire. Close up 5 to 6 times, and then cut off the excess thread.
②When connecting large-section single-strand copper wires, first fill in a core wire with the same diameter at the overlap of the two wires and then wrap it tightly with a bare copper wire with a cross-section of about 1.5mm2, and the winding length is about 10% of the wire diameter. times, and then fold back the ends of the core wires of the connecting wires respectively, and then continue to wrap the bare copper wires at both ends for 5 to 6 turns, and then cut off the excess wire ends.
(3) When connecting single copper wires of different cross-sections, first wrap the core wire of the thin wire tightly around the core wire of the thick wire for 5 to 6 turns, then fold the end of the thick wire back and press it tightly on the winding layer, and then continue to wind the core wire of the thin wire 3 to 4 turns and cut off the excess wire ends.
Branch connections for quick connectors
Tightly wrap the end of the branch core wire around the main core wire for 5 to 8 turns, and cut off the excess end to realize the t-shaped branch connection of a single copper wire. For core wires with smaller cross-sections, tie the end of the branch core wire with a winding knot on the main core wire, and cut off the excess thread after winding 5 to 8 turns.
Shorting connection of the quick connector
Shorting the connection can make the connector wiring faster, directly press with pliers, and can also be insulated to effectively prevent poor contact. The shorting nut can also short-circuit the wires, twist the two wires together, and then screw them on with the shorting nut, which is also very firm.
The above three are the most commonly used wiring methods. To say which wiring method is the fastest in the connector, it must be to cut the wire directly, twist the two wires to be connected directly together, and then seal with insulating tape. However, this approach is too violent, which is likely to cause poor contact and easily affect production work. In addition to that, you can also directly solder the two wires with a soldering iron, which is safer.
