Spring-Loaded Contacts with Solder-Cups

Mill-Max spring-loaded pins and connectors, provide a highly-reliable, precision made interconnect solution ideal for a number of demanding application requirements. Spring-loaded pins with an integrated solder-cup offer a unique combination of interconnect options, such as battery leads soldered to spring pins mounted in a docking/charging station. The spring-loaded pin with solder-cup feature enables efficient attachment of wires while the spring-loaded plunger is the proper interface for mating to devices with pads or lands. Several of the spring-loaded pins include a press-fit feature for convenient mounting in assembly housings or boards.

In the example shown here, the 0973 spring-loaded pins are used in a cable assembly as part of a quick-connect system. In this application the wires are passed through the housing where they are soldered to the cups. The wires and pins are pulled back through the housing until the press-fit feature is engaged, then, pushing on the shoulders of the pins, they are secured into the housing. The spring pins are designed with the location of the shoulder and barb press-fit feature to ensure the pins will not be pulled from the insulator due to strain on the wires.
