Fuse and Relay Box

Fuses are important in electrical circuitry ofcars. When the current passing through a fuse exceeds a certain defined limit, the fuse will blow, protecting the wires they are connected to.. Relays are a switching devices that use a small electrical current to control a much larger current in a second circuit. When a relay is turned on, it routes power to this second circuit.

Interplex’s customized solutions for fuses and relays include busbars, connector headers, and terminals, and ensure the fuse and relay boxes in vehicles function as they reliably should.

Busbars

Busbars are the backbones for power applications across industries and a mainstay in electrical power distribution, conversion and management devices. They provide critical interfaces between power modules and the external systems these modules drive— for example, power steering ECUs, fuse and relay boxes, and DC-DC inverters in EV and HEV engines.

Interplex’s busbars are excellent for power intensive applications and are customizable to suit your current transmission requirements and performance specifications. Possible options include laminated/insulated busbars, flexible busbars, multi-layer molded busbars, and busbars integrated with high-force Press-Fit solderless interconnects.

No matter the thickness, shape or form you need, Interplex can stamp busbars to your desired thickness, bend them to the required shapes, plate them in a variety of materials, all while maintaining high performance standards and required structural integrity.

Connector Headers

Connector headers are electrical connectors with one or more rows of male pins spaced apart within an insert molded body. Interplex’s connector headers provide good mating retention for reliable connections in a large variety of end applications and sub-systems, and we can support you every step of the way with numerous pin count and pitch options, current carrying capacities, pin orientations (vertical/right angles) and wire sizes.

Our full suite of capabilities enable us to reliably precision stamp metal and mold plastic (pre-molding, overmolding and insert molding) that is required for connector headers. These processes are complemented with a comprehensive range of value-added processes such as plating and potting.

Terminals

Interplex’s terminals are trusted by top-tier automotive companies for a myriad of end applications within cars. Available options include terminal pins, clips and contacts, and these can be delivered to you in various forms— singulated or in strips.

Our terminals are used in many end applications such as: Within plug-in relays, as interconnects between PCB and relays, within various ECUs, as motor/harness connectors to infotainment systems and power windows, and between user interface switches to their respective sub-systems (such as headlights, air-conditioners).

Our full suite of capabilities enables us to precision stamp and plate intricate terminals in various shapes and sizes to fulfil your end application needs. Our in-house skiving equipment can also contour metal thicknesses and configurations as required.
