How do I choose rast connectors?

The design of electronic products is becoming more and more modular. The organic combination of different functional modules can quickly create high-quality products with different performances, and the connection of the modules is particularly important.

The rast connector is like the functional interface of the program. If the design of rast connector is reasonable, in the future, product maintenance, upgrades, and transplantation will get twice the result with half the effort. As a result, the product can maintain vitality for a longer time. The unreasonable design will cause difficulties in future maintenance and upgrade, which will affect the whole part of electronic devices. In the end, the product loses its competitiveness. Therefore, the importance of the connector is self-evident.

Below are some knowledge points about rast connectors:

What are rast connectors?

Types of rast connectors

How to choose rast connectors?

(1) What are rast connectors?

Rast connectors, which are commonly used by engineers, are used to connect two circuit boards or electronic devices to achieve power or signal transmission. Through the rast connector, the circuit can be a module, the assembly process of the electronic product can be simplified, and the product can be easily maintained and upgraded. Therefore, they have a great impact on electronic devices.

(2) Types of rast connectors

There are many types of connectors. Common types include communication interface terminals, wiring terminals, wire-to-board connectors, and board-to-board connectors. Each category can be subdivided into several categories, such as Board-to-board connectors include header and female headers, PC104, board-to-board connectors, etc.; wire-to-board connectors include FPC connectors, IDC sockets, simple horn sockets, etc.

(3) How to choose rast connectors?

When you are choosing proper rast connectors, you could focus more on the indicators listed below.

1. The number of pins and the spacing between pins are the basic basis for rast connector selection. The number of pins selected for the connector depends on the number of signals that need to be connected. For some SMD connectors, the number of pins should not be too much. Because in the soldering process of the placement machine, due to high temperature, the connector plastic will be heated and deformed, and the middle part will bulge, resulting in false soldering of the pins. Nowadays, electronic equipment is developing towards miniaturization and precision, and the pin pitch of the rast connector has also changed from 2.54mm to 1.27mm and then to 0.5mm. The smaller the lead pitch, the higher the requirements for the production process. The lead spacing should be determined by the company's production technology level. The blind pursuit of small spacing will cause difficulties in production and maintenance.

2. The three performance of rast connectors should be considered. They are mechanical performance, electrical performance and environmental performance. The mechanical property of rast connector means the mechanical life of the connector. Mechanical life actually refers to a kind of durability. The main electrical properties of electrical rast connectors mainly include contact resistance, insulation resistance and electrical strength. Environmental performance includes temperature resistance, humidity resistance, salt spray resistance, vibration and shock resistance, etc.

We can provide many kinds of rast connectors like rast 2.5 connectors, rast 2.5 power connectors, rast 5.0 connectors, circular connectors, wire to wire connector wire to board connector, etc. Or we can design according to your requirements.
