The size and nature of the current

Connectors are important electrical components of the car body, and their most essential function is to transmit electrical signals and current. Therefore, the size of the current directly determines the type of connector selected.

There are many factors that affect the current transmission of automotive connectors. The size of the rated current is the indicator we focus on. The rated current is also called the operating current. Generally, the operating current of a connector can be less than the rated current.

For connectors, the final manifestation of current is the final conduction between terminals. In actual applications, because the conductor end

There will be contact resistance during the contact process. If used for a long time, the temperature of the conductor accessories will increase.

The increase in temperature around the conductor accessories will worsen the softening of the terminal surface coating, which may lead to electrical failure in severe cases. Therefore, when designing the input, the ambient temperature of the terminal must be considered.

Requirements for the number of holes

Connectors The most basic element when considering design input is the number of holes required in the connector. Generally, a connector with a similar number of holes or a slightly larger number of holes will be selected.

In this way, there is no need to replace new connectors when the automotive platform is used. However, the number of reserved holes should not be too many. Too many holes will cause excess functions and increase costs.

Generally, it can be used as a reference based on the subjective requirements of the OEM. When selecting a waterproof connector, you must consider that the excess holes must be blocked with sealing plugs, otherwise the sealing effect will not be achieved.

Requirements for terminal tail models

The selection of connector terminals mainly takes into account two factors: one is the size of the required current, and the other is the size of the adapting wire diameter. These two factors are also complementary to each other. When a large wire diameter is required, the current carrying capacity of the required terminals will also be required to be larger; when the required current is smaller, the wire diameter requirements of the required terminals will also be smaller.

Assembly force requirements

The size of the assembly force is in the connector label, also called the bonding force. This bonding force refers to the amount of force required when the male and female ends of the connector are mated with each other. In principle, the smaller the assembly force, the better. If the size of the assembly force is classified according to the connector structure, it can be divided into assistless structure connectors and assistant structure connectors.
