Rectangular connectors refer to electrical connectors that are rectangularly shaped. These include headers, receptacles, and female sockets. A 499-43-210-10-003000 belongs to this group. This article looks at its application field and working principle in more detail.

Application field of 499-43-210-10-003000

The 499-43-210-10-003000 is an IDC terminal applicator that belongs to Harwin’s family of applicators – the EMC range. This is a manually operated applicator designed for standard pitch ranges from 0.5mm to 2.5mm wires. The applicator is also suitable for telescopic systems and fixed pitch connectors such as the J, H, V and S series connectors, depending on the wire size and spacing adopted.

The notable application domain of 499-43-210-10-003000 includes cable harnessing/cable assembly, as well as for use in flexible printed circuit board (FPCB) assembly. The targeted applications are Electronic Control Units (ECUs), instruments, motion control and solid state relays.

Working Principle of 499-43-210-10-003000

499-43-210-10-003000 uses a slide-on mechanism to fasten the IDC (Insulation Displacement Connector) connector onto the cable. This slide-on IDC connector fastener ensures low insertion forces, maximum retention forces and better contact reliability. The applicator allows users to manually apply IDC connectors to the wire of choice.

The applicator features a twin-hammer cam mechanism, which is composed of two gear camsshafts alongside two staggered gears for ease of operation. In order to be used properly, a correctly sized IDC die needs to be fitted to the applicator for insertion into the IDC contact housing after the IDC contact has been inserted into the wire insulation. Then the IDC contact is aligned into the die and the single handle of the applicator is squeezed in an up-and-down motion to crimp the contact.

The applicator is tested in accordance with applicable international standards. All applicators are checked with a minimum of 10,000 cycles for quality assurance. The clamping force tests ensure a reliable contact force between the IDC contact and the die.

Conclusion

The 499-43-210-10-003000 is a manually operated terminal applicator suitable for wire sizes from 0.5mm to 2.5mm. It is designed for the application of IDC (Insulation Displacement Connector) connectors. The applicator features twin-hammer cam mechanism and is tested to ensure reliability and contact force. The 499-43-210-10-003000 is typically used for Electronic Control Units, instruments, motion control and solid state relays.
