DEFINITION OF TERMS

  • Automotive Vehicles – These are motor vehicles whose gross vehicle weight is equal or less than 3,500 kgs. Powered by a gas or diesel engine. It could be a passenger car or a light utility vehicle
  • Automotive Electrical Assembly Technician – Refers to an all around auto electrical assembly man that can perform all electrical assembly works from assembling of electrical assemblies to mounting and installation to automotive vehicle body.
  • Adhesives – Substance used to hold gasket in place during assembly. It also maintains a tight seal by filling in small irregularities on a surface and prevents gasket from shifting due to vibration.
  • Point of Fit – Refers to the assembly area where parts / materials / assemblies are used or consumed
  • Electronics – Electrical assemblies, circuit and system that use electronic devices such as transistors and diodes
  • Hardware Parts – Refers to bolts, nuts, screws, washers and other small parts
  • Catalytic Converter – Emission The control device fitted in the exhaust system of an internal combustion engine. The converter reduces the toxicity of products of combustion by catalytic re-combination
  • Assembly Manuals – Reference manuals with illustration or drawings of parts/components and its direction on how they are mounted or installed on the automotive vehicle or certain assemblies.
  • Quality Inspection Manuals – Reference manuals with explanation on what quality standards have to be maintained in the conduct of assembling automotive vehicle
  • Work Order – A work order is a form of instruction that is broadcasted either by manual or by electronic system by preceding stations to the next stations regarding on what model sequence to produce on a timely-structured manner.
  • Job Requirements – Refers to specific specifications of model/variant to be assembled.
  • Standard Operation Sheet –  Is a listing of process elements arrange according to the assembly sequence for a given job requirements
  • Fuel Injection – An electronic system that increases the performance ad fuel economy because it monitors engine conditions and provides the correct air/fuel mixture based on the engine’s demand. It injects fuel directly into the cylinder head enabling more precise control over the quantity used.
  • Jigs/fixtures – Kind of equipment that is used for sub-assembly operations in order to meet the desired dimensions and outcome of a certain assembly.
  • Crimping – Joining two pieces of metal or other malleable material by deforming one or both of them to hold the other. The bend or deformity is called the crimp. Crimping is most extensively used in metalworking. It is not generally used of specialized connectors that are designed to be deformed, but only of workpieces. Crimping is commonly used to join bullets to their cartridge cases, and for rapid but lasting electrical connectors. Because it can be a coldworking technique, crimping can also be used to form a strong bond between the workpiece and a non-metallic component. Sometimes, a similar deformity created for reasons other than forming a join may also be called a crimp
  • Wiring harness – Wire harness also known as cable harness, cable assembly, wiring assembly or wiring loom; is a string of cables and/or wires which transmit informational signals or operating currents (energy). The cables are bound together by clamps, cable ties, sleeves, electrical tape, conduit, a weave of extruded string, or a combination thereof.

    Commonly utilized in automobiles, as well as construction machinery, modern-day cable harnesses provide several advantages over loose wires and cables. For example, many aircraft, automobiles and spacecraft contain many masses of wires which would stretch over several kilometers if fully extended. By binding the many wires and cables into a cable harness, the wires and cables can be better secured against the adverse effects of vibrations, abrasions, and moisture. By constricting the wires into a non-flexing bundle, usage of space is optimized, and the risk of a short is decreased. Since the installer has only one harness to install (as opposed to multiple wires), installation time is decreased and the process can be easily standardized. Binding the wires into a flame-retardant sleeve also lowers the risk of electrical fires.
