Do you know the basic structure of automotive connectors?

Automotive connectors are a component often contacted by electrical engineering technicians. Its role is very simple: between the blocked or isolated circuits in the circuit, a bridge is established to communicate, so that the current flows and the circuit achieve the intended function. The form and structure of automotive connectors are ever-changing. They are mainly composed of four basic structural components: contact parts, housings (depending on the variety), insulators, and accessories. In the industry, it is also commonly called sheath, connector, and plastic case.

About Automotive Connectors

There are nearly a hundred types of connectors used in general cars, and there are hundreds of connectors used in a single-vehicle. As people have higher and higher requirements for cars in terms of safety, environmental protection, comfort, and intelligence, the application of automotive electronics is increasing, which will increase the number of automotive connector applications. Our company has a FAKRA Connector.

As a FAKRA Long Female Connector Factory, I will introduce the four basic structural components of automotive connectors.

First, the contact is the core part of the automotive connector to complete the electrical connection function. The contact pair is generally composed of a positive contact and negative contact, and the electrical connection is completed by the mating of the female and male contacts.

The male contact is a rigid part, and its shape is cylindrical, square or flat. The male contact is generally made of brass or phosphor bronze. The female contact is the jack, which is the key part of the contact pair. It relies on the elastic structure to elastically deform when mating with the pin to generate elastic force to form close contact with the male contact to complete the connection. There are many types of jacks, including cylindrical, tuning fork, cantilever, box, and hyperboloid wire spring jacks.

Second, the shell is the cover of the automotive connector, which provides mechanical protection for the built-in insulation mounting plate and pins, and provides alignment when the plug and socket are mated, thereby fixing the connector to the device.

Third, insulators, insulators are often referred to as automobile connector bases or inserts. Its role is to arrange the contacts in the required position and spacing, and to ensure the insulation between the contacts and between the contacts and the shell. Good insulation resistance, voltage resistance and easy processability are the basic requirements for selecting insulating materials for processing into insulators.

Fourth, accessories, attachments are divided into structural accessories and installation accessories. Structural accessories such as collars, positioning keys, positioning pins, guide pins, coupling rings, cable clamps, seals, gaskets, etc. Installation accessories such as screws, nuts, screws, spring coils, etc. Most of the accessories are standard parts and universal parts.

It is these four basic structural components that enable automotive connectors to act as bridges for stable operation. Our company also has Auto FAKRA Connector on sale, welcome to consult.
