SFM-145-02-H-D is a kind of rectangular connectors widely used in industries. It is mainly composed of plastic housing, spring-loaded clip, and contact terminal, etc. This kind of connector is a kind of headers connector, which is mainly used to connect two pieces of PCB boards. It mainly includes two parts:

The first part is the header which is generally composed of a plastic housing and spring-loaded clip. The plastic housing contains contact terminal which can clamp the material of hole wall on PCB board tightly. The spring-loaded clip makes the terminals in plastic housing of header become plane shape. In this way, the header can be closely connected with PCB board to make sure good contact and strong clamping effect.

The other part is the receptacles which generally includes metal shell and contact terminal. Comparing with header, the contact terminal of receptacles has elastic character. Its elasticity can match with the header more closely. After installation and connecting, the header and the receptacles can be tightly locked.

The working principle of SFM-145-02-H-D rectangular connectors is not complicated. When moving the copper needles into the terminal cavity of the connectors, they pierce through the perforated copper plate and clip into the terminal cavity inside the header. The side of the contact terminal in the header is inserted into the hole on the PCB board. At the same time, the metal shell of the receptacles also penetrates into the hole. Then the clip at the end of the header tightly secures the contact terminal, and the contact terminal of the header is in contact with the PCB board. At this time, due to the elasticity of the contact terminal of the receptacles, the contact terminals of the two parts can be closely combined. Thus, the electrical connection between two sides is realized.

SFM-145-02-H-D connectors have good connection performance and stable operation. It can be used in many application fields. For examples, it can be applied in the fields of automobile, bike, motorcycle, electronic equipments, digital products, industrial control systems, lighting systems, and computer motherboards due to its high performance, wide range of applications, and great reliability.

Besides its wide application fields, these rectangular connectors also have many advantages，such as good waterproof performance, resistance to electric erosion, easy installation, and wide temperature range. They are also suitable for environment with highly electromagnetic interferences, which makes them ideal choice for many electronic devices.

Overall, SFM-145-02-H-D rectangular connectors are a kind of durable, safe, and reliable connectors, which can be widely applied in various fields due to its good performance. Its working principle is not complicated, and it has many advantages such as good waterproof performance, resistance to electric erosion, easy installation, and wide temperature range.
