Below, many years of production experience master from the use of the PIN needle environment, the basic structure of the connector, to give you a brief introduction:

1. before understanding the role of the pin in the connector, we want to say what is the connector?

The connector is a component that our electronic engineering and technical personnel often come into contact with. Its function is to set up a bridge of communication between the blocked or isolated circuits in the circuit, so as to use the current flow and make the circuit realize the predetermined function.

The form and structure of the connector are ever-changing. With the application object, frequency, power, application environment, etc., there are various forms of connectors. For example, the connector used to light the lights on the court is very different from the connector of the hard drive, and the connector used to light the rocket. However, no matter what kind of connector it is, it is necessary to ensure the smooth and reliable flow of current.

Connected by the connector is not limited to the current, in the rapid development of optoelectronic technology today, the optical fiber system, the carrier of the transmission signal is light, glass and plastic instead of the wires in the ordinary circuit, but the optical signal path also uses the connector, Their role is the same as the electrical connector.

Why should 2. use connectors?

Let's take an example, such as our car battery. Assuming that the battery cable is fixed and welded on the battery, the automobile manufacturer increases the workload for installing the battery, increasing the production time and cost. When the battery is damaged and needs to be replaced, the car must be sent to the repair station, the old one must be removed from the welding, and the new one must be welded. For this reason, more labor costs must be paid. With the connector, you can avoid a lot of trouble. Buy a new battery from the store, disconnect the connector, remove the old battery, install the new battery, and reconnect the connector. This simple example illustrates the benefits of connectors. It makes the design and production process more convenient and flexible, and reduces production and maintenance costs.

Basic structure of 3. connector

The basic structural parts of the connector are: contacts, insulators, shells, and accessories.

The contact is the core part of the connector to complete the electrical connection function. Generally, a contact pair is composed of a male contact and a female contact, and the electrical connection is completed by inserting the female and male contacts.

The male contact is a rigid part, and its shape is cylindrical (round pin), square pillar (square pin) or flat (blade). The male contact is generally made of brass or phosphor bronze.

The female contact is the socket, which is the key part of the contact pair. It relies on the elastic structure to deform elastically when it is inserted with the pin to generate elastic force to form close contact with the male contact to complete the connection. There are many kinds of jack structures, including cylinder type (split slot, constriction), tuning fork type, cantilever beam type (longitudinal slot), folding type (longitudinal slot, 9-shaped), box type (square jack) and hyperboloid wire spring jack.
