RJ45 Connector The Main Role Is Information Communication And Power Supply
发布时间:2018-05-07 14:10:10 | 浏览次数：

The RJ45 connector is a component that an electronic engineering skill person often touches. Its effect is very simple: in the circuit is blocked or isolated between the circuit, set up a bridge of the exchange, so that the current flow, so that the circuit to achieve the function of booking

RJ45 network connector is not limited to the current, in the rapid development of optoelectronic skills today, the fiber system, the transmission signal carrier is light, glass and plastic instead of the ordinary circuit of the wire, but the optical signal path is also used Connectors, the same effect as the circuit connector.

RJ45 connector is not a small part of the electronic components, along the current flow of the survey, you can find one or more connectors. Connector mode and structure is ever-changing, followed by the use of goals, frequency, power, the use of the environment is not the same, there are different ways of ultra-thin connector. For example, the connector on the pitch and the connector of the hard drive, and the connector that ignites the rocket are quite different. But no matter what kind of connector, must ensure that the smooth flow of current and flow to the reliability.

RJ45 connector is the main role of information communication and power supply, by the plug and socket components. The connectors of these two components are connected between the wires to achieve electrical continuity of the wires. Therefore, RJ45 connector is generally used in the field of LED lighting equipment, security equipment, telephone communications equipment, home office, network equipment, financial institutions and other areas.

RJ45 network connector has three basic structures: 1, contact; 2, insulator; 3, shielding shell (depending on the type may be).

1, contact (contact) is RJ45 network connector to complete the electrical connection function of the core parts. Generally by the positive contact and the negative contact with the composition of the contact, through the yin and yang contact to complete the electrical connection. The positive contact is a rigid part, its shape is cylindrical (round pin), square cylindrical (square pin) or flat (insert). Positive contacts are generally made of brass, phosphor bronze. The negative contact, the jack, is the key part of the contact pair, which is resiliently deformed by the elastic structure in contact with the pin to create a resilient force in close contact with the positive contact to complete the connection.

2, insulator. Insulators are often referred to as the main body, base or insert, and the effect is to align the contacts in the desired position and spacing and to ensure that the contacts between the RJ45 network connector and the contacts Between the insulation performance. Good insulation resistance, withstand voltage performance and ease of processing is the basic requirement for selecting insulating materials.

3, shell. Also known as a shield, it is a housing of an RJ45 network connector that provides mechanical protection for built-in insulators and contacts and provides alignment of the plug and socket when the connector is secured to the device.
