How to choose the connector? Construction machinery connection system manufacturers tell you that 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 headers and females, board-to-board connectors, etc.; wire-to-board connectors include FPC connectors, IDC sockets, and simple horn sockets. The following construction machinery connection system manufacturers will introduce.

Construction machinery connection system manufacturers inform us that we have to choose from the following aspects when choosing.
1. Pins and spacing
Construction machinery connection system manufacturers inform that the number of pins and pin spacing are the basic basis for connector selection. The number of pins selected for the connector depends on the number of signals that need to be connected. For some patch connectors, the number of pins in the patch headers as shown in the figure below should not be too much. Because in the soldering process of the placement machine, due to the effect of high temperature, the connector plastic will be heated and deformed, and the middle part will bulge, resulting in false soldering of the pins. We used this kind of header and female header to make the board-to-board connection in the early stage of research and development. As a result, the pins of the prototype header were soldered in a large area. After changing to 2 pin headers with halved pins, there was no false soldering.
Nowadays, electronic equipment is developing towards miniaturization and precision, and the pin pitch of the 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, blindly pursue small spacing
2. Electrical performance
Construction machinery connection system manufacturers inform that the electrical performance of the connector mainly includes: limiting current, contact resistance, insulation resistance and dielectric strength, etc. When connecting a high-power power supply, pay attention to the limit current of the connector; when transmitting high-frequency signals such as LVDS, PCIe, etc., pay attention to the contact resistance. The connector should have a low and constant contact resistance, generally tens of mΩ to hundreds of mΩ.
3. Environmental performance
The manufacturer of Construction machinery connection system informs that the environmental performance of the connector mainly includes: temperature resistance, humidity resistance, salt spray resistance, vibration, impact, etc. Choose according to the specific application environment. If the application environment is relatively humid, the requirements for resistance to humidity and salt spray of the connector are high to prevent the metal contacts of the connector from being corroded. In the field of industrial control, the requirements for the anti-vibration and impact performance of the connector are high, so as to prevent the connector from falling off during the vibration process.
4. Mechanical properties
The manufacturer of Construction machinery connection system informs that the mechanical properties of the connector include insertion force, mechanical foolproofness, etc. Mechanical foolproof is very important to the connector. Once it is inserted reversely, it may cause irreversible damage to the circuit!
The insertion force is divided into insertion force and separation force. The relevant standards stipulate large insertion force and small separation force. From the perspective of use, the insertion force should be small and the separation force should be large. Too little separation force will reduce the reliability of contact, but for connectors that often need to be plugged and unplugged, too much separation force will increase the difficulty of unplugging and reduce the mechanical life.
In order to reduce the separation force of the connector and make it easier for users to plug and unplug the adapter board, the Construction machinery connection system manufacturer has made many attempts, and finally found a bright light on the road of groping.
Connectors, which are commonly called connectors by engineers, are used to connect two circuit boards or electronic devices to achieve power or signal transmission. Through the connector, you can make the circuit module
Simplify the assembly process of electronic products and make the products easy to maintain and upgrade. For modular circuits, the manufacturer of Construction machinery connection system informs that the selection of connectors plays a decisive role.
