Rectangular connectors can be used as the connecting elements between wiring and electrical circuits, and form a type of electrical contact. It is widely used in all types of machinery and electrical instruments. It has the advantages of simple structure, strong integrity, high reliability, convenient connection and installment. HLE-149-02-SM-DV-TE is one of the representative products for rectangular connectors. This article will explain the application field and its basic working principle.

1. Application Field

HLE-149-02-SM-DV-TE is a kind of female socket connector with two round holes. This connector is usually applied for the connection with wires or cores with 2.54mm pitch, 1.0mm spacing and 1.5A/contact current. Besides, it also has the unique feature to bear 175℃ high temperature, thus being highly suitable for use in wires with high temperature. Generally speaking, it is widely applicable for the connection between PCB and harness assembly, as well as for various kinds of electrical appliance. Its miniaturized type connector is very convenient for integrated elements in a narrow space and also improves the design’s space-saving and appearance.

Instrumentation and medical instrument are also the main application field for HLE-149-02-SM-DV-TE. Its miniaturized feature is very helpful to be applied in fields with limited space, such as medical instrument. The wire harness for the electrical connection of instrumentation is also conducted through this connector, because it can provide the reliable electrical connection between PCB boards and harness assembly. Hence HLE-149-02-SM-DV-TE is very suitable for connection transfers of instrumentations and medical instruments.

2. Working Principle

HLE-149-02-SM-DV-TE female socket is composed with the contact pins and metal holders. The contact pins are soldered or welded to the board and have insulation housing which is fastened with rivets. The contact pins and heads can be formed by stamping brass or copper materials. During use, the pin housing is placed inside the metal holder. The metal holder has two posts on each side, which can be directly connected to the board. The contacts of the contact pin and metal holder are connected when external force is applied, and the electrical connection is established. The contact pins have spring characteristics, which can move back and forth under external force, thus making sure the contact pins and metal holders have a more reliable connection.

High temperature-resistant HLE-149-02-SM-DV-TE connectors have the same working principle as normal types. But in order to have better heat resistance, the contact pins and metal holders which are formed by zinc alloy or stainless steel and with plating are adopted to ensure that the current flow cannot be blocked even in high temperature circumstance. Hence, this connector can guarantee a stable connection between electrical circuits under the wide range of temperature.

Conclusion

In conclusion, HLE-149-02-SM-DV-TE female socket connector is widely applicable in PCB-harness assembly and instrumentation field due to its reliable electrical contact, simple connection and high temperature resistance. Its reliable working principle is major contributor for its overall trustworthiness.
