As vibration resistance is of the essence for power tool manufacturers, the poke-in terminal’s design turns the secondary IDC slot into a strain relief. This further improves the already high level of MAG-MATE interconnection reliability. The resilience of the tin-plated brass beams, forming the poke-in terminal’s two slots, allows a gas-tight electrical connection with the wire plus enhanced strain relief. When the metal terminal is inserted in the plastic cavity (≈ housing), the positive connection between terminal and cavity wall prevents relaxation over time, thus making the interconnection extremely durable.
MAG-MATE poke-in terminals offer yet another advantage to power tool applications because space constraints can be addressed during the design-in of the plastic cavity. TE Connectivity engineering offers global design-in support, welcoming diverse business models, ranging from full design-in at TE Connectivity to the mere provision of CAD models for use at the customer’s lab.
The UL approved poke-in terminal is available in two sizes (types B and D) covering between them a wide range of copper wire gauges from 0.36 to 1.83 millimeters (AWG 27 – 13).
Recent studies at TE Connectivity have shown that standard MAG-MATE interconnection products will work very well with aluminum magnet wire, if the insertion depth of the terminal is specified for the light weight material’s properties. As a consequence the switch to poke-in terminal technology is future-proof even if the power tool manufacturer considers using aluminum magnet wire instead of copper.
