What happens when a car doesn't have a board-to-board connector?

Imagine what would happen if there were no board-to-board connectors? At this time, the circuits must be permanently connected together by continuous conductors. For example, if a certain device is to be connected to the power supply, it is necessary to fix the ends of the connecting wires to the electronic equipment and the power supply by some means. prison. In this way, no matter the production is still used, it brings a lot of inconvenience.

The importance of using board-to-board connectors

 

In the case of such high vehicle usage, sensitivity and safety are more important for various lines in the car. Sometimes used in harsh environments where plugging and unplugging is required, then using a board-to-board connector would be the right choice.

 

A typical light vehicle has approximately 1,500 connection points, of which 50% to 60% are used for critical power distribution functions. Automotive connectors are used in increasingly harsh environments, including temperatures (down to minus 40°C, up to minus 155°C), vibration, oxidation, and frictional corrosion, demonstrating the importance of connectors. In fact, this thing is not easy to do. If there is a problem with the connection of key auto parts, it will cause the fire alarm, brake or airbag to malfunction, resulting in serious consequences.

 

Board-to-board connectors make automotive systems more convenient, more sensitive, and safer in planning and production, as well as lower production and protection costs. The board-to-board connector improves the production process, and the connector simplifies the electronics assembly process and simplifies the mass production process for easy maintenance. If an electronic component in the car fails, the connector can be quickly replaced with a failed component, and the connector is easy to upgrade. With advances in technology, a single-slot connector with a connector Ability to update meta-components, replace the sensitivity of old progressive plans with new, more sophisticated components. The use of adapters allows engineers to be more sensitive when planning and integrating new products, as well as using component-based systems. 

 

How to choose a board-to-board connector

 

There are many types of connectors, and common types include communication interface terminals, terminal blocks, wire-to-board connectors, and board-to-board connectors. So from what point of view should we consider connectors suitable for hardware use when selecting connectors?

 

Pin, pitch

The pin count and pin pitch are the basic basis for connector selection. The number of connectors that choose how many pins depends on the number of signals that need to be connected. Nowadays, electronic devices are becoming smaller and more precise, and the pitch of the connectors is also from 2.54 mm to 1.27 mm to 0.5 mm. The smaller the pin pitch, the higher the requirements for the production process.

 

Electrical performance

The electrical properties of the connector mainly include: limiting current, contact resistance, insulation resistance and electrical strength. 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, typically tens of mΩ to hundreds of mΩ.

 

Environmental performance

The environmental performance of the connector mainly includes: temperature resistance, moisture resistance, salt spray resistance, vibration, impact and the like. Choose according to the specific application environment. If the application environment is relatively humid, the requirements for moisture and salt spray resistance of the connector are high, and the metal contacts of the connector are prevented from being rusted.

 

Mechanical behavior

The mechanical properties of the connector include the insertion and extraction force, mechanical foolproofing, and the like. Mechanical foolproof is very important to the connector. Once inserted, it is likely to cause irreversible damage to the circuit!

 

summary

 

The importance of board-to-board connectors is believed to be clear to you, so choosing the right board-to-board connector is what you need to do next. If you are choosing a connector for your car manufacturing, you can come to know us.
