Rectangular Connectors – Headers, Male Pins: 87283-5 Application Field and Working Principle

Rectangular connectors commonly referred to as headers and male pins, are widely used in electronic devices, ranging from home appliances, PCs, and medical devices, to automotive and military products. At its core, a rectangular connector consisting of a header and male pin is a mechanical and electrical connection device made up of various components, including metal shells, stents, plating, terminals and insulators. This article will focus on 87283-5 pin-through-hole application field and working principle.

87283-5 Application Field

87283-5 pin-through-hole type is a type of connector which is used for automatically soldering on a printed circuit board. Its differentiating features include an enlarged applicable range and improved wave soldering performance. This variety of connector has a metal shell and can withstand a variety of environment impacts. Apart from being used in usual electronic products, its contact design allows it to be used in automotive, aerospace and military products with high environmental requirements. 87283-5 pin through hole connectors are also used for printed circuit boards with strong interference, and its internal insulation structure isolates the current.

87283-5 Working Principle

The 87283-5 type is based on the pin-through-hole structure, and utilizes a metal shell to wrap the connector’s plating, terminals and insulators. The working principle of this specific model can be broken down into 7 steps.

Step one, the metal shell of the connector is fixed in the printing hole of the printed circuit board using the plastic housing. Due to the threads in the insulation parts, the connector is linked to the circuit board in a reliable manner.

Step two, the terminals of the connector are inserted into the printing holes of the board via the mounting holes of the metal shell.

Step three, the terminal insertion sequence and height need to be checked according to requirements described in the working manual.

Step four, the bottom of the connector after soldering needs to be checked for correctness.

Step five, the wave soldering needs to be inspected to verify whether the terminal pins of the connector are soldered correctly.

Step six, wave soldering temperature needs to be adjusted to 180 - 200 degrees C.

Step seven, the finished product needs to be inspected for current-resistance to ensure stability and accuracy.

In conclusion, the 87283-5 rectangular connector not only offers reliable, economical and easy-to-use solutions for applications on printed circuit board, but also provides excellent electromagnetic compatibility and performance.
