Standards and performance for Automotive Connectors?

Nowadays, a large part of automotive electronics products is compatible designs for different car companies. Regardless of internal compatibility, the specific external interface needs to determine the connection interface requirements, including the installation location, structure and electrical content. A prominent problem is the choice of connectors. FAKRA Auto Connector and wiring harness are carriers for electric signal control of the car. It connects the vehicle's central control part with the car control unit, electric and electronic execution unit, and electrical components to form a complete car electrical control system. The content and quantity of automotive connectors and wiring harnesses in automotive electronics are also an important indicator of automotive functionality and performance.

FAKRA Auto Connector

From the perspective of performance, we must first look at the material and process of the connector. As a Car Phone FAKRA Connector Factory, share with you.

If we follow the car's process requirements, including the terminal, housing, and sealing processes, we will focus on reviewing. When choosing a connector, from what angles should we consider connectors suitable for hardware use?

Mechanical properties: The mechanical properties of the connector include mechanical life, mating force, mechanical foolproof, etc.

1. Mechanical durability: Take one insertion and one extraction as a cycle, and judge whether the connector can normally complete its connection function after the specified insertion and removal cycle.

2. Insertion and extraction force: It is an important mechanical property. The insertion and extraction force is divided into the insertion force and extraction force (separation force). The insertion force should be small (thus the structure with low insertion force LIF and no insertion force ZIF), and if the separation force is too small, it will affect the reliability of the contact. The insertion force and mechanical life of the connector are related to the quality of the plating on the contact part of the contact structure and the accuracy of the contact arrangement dimension. Here you can also subdivide slightly:

a) Terminal insertion force refers to the maximum force consumed by the terminal after it is inserted into the Housing.

b) Terminal holding force refers to the minimum force that the terminal consumes when it leaves the housing.

c) Insertion force refers to the maximum force to be inserted when the male seat and the female seat are mated.

d) Withdrawal force refers to the minimum force required to pull out when the male seat and the female seat cooperate.

e) The PIN holding force is the minimum force required to disengage the PIN in Wafer from its insulator.

Electrical performance: The electrical performance of the connector mainly includes: limit current, contact resistance, insulation resistance and electrical strength.

1. Rated voltage: The maximum working voltage recommended by the manufacturer, mainly depends on the insulation material used and the distance between the contact pairs. When some components or devices are below their rated voltage, they may not be able to perform their intended functions. The FAKRA Connector can work normally below the rated voltage.
