Classification of waterproof connectors

Waterproof connector on the market is more conventional wire to wire waterproof connector, wire to board waterproof connector, board to board waterproof connector 3, in all walks of life are applied to most and electrical and electronic products, its role is used to connect power and communication, so that waterproof and anti-splash or wading can also ensure the normal power interconnection and communication transmission of equipment.Electrical and electronic equipment itself circuit complex + plus the control board, the natural environment and various factors will affect it, so the connector waterproof and dust-proof is necessary, waterproof connector intuitively speaking is the protective effect, if you do not understand the waterproof connector, the following can be understood in detail under the waterproof connection through this article.

The biggest advantage of the waterproof connector is that it has good waterproof performance characteristics, the great advantage of the waterproof connector is, of course, in the waterproof characteristics, to prevent the entry of water and erosion, and to prevent dust from entering the connector leading to its performance decline, waterproof connector can ensure that the electrical performance in use is not affected by external factors, to ensure that the internal mechanical equipment is not damaged.The use of a good shell also ensures the stability of electrical performance, but also has the characteristics of high temperature resistance and pressure resistance.

The following three waterproof connectors are introduced:

According to the structure type or function differentiation: wire-to-wire waterproof connector, wire-to-board waterproof connector, board-to-board waterproof connector.

1. Wire-to-wire waterproof connector.Wire-to-wire connection also includes the form of wire-to-cable or cable-to-cable, which is defined by the long distance connection between two single wire individuals or the corresponding wires in two cables.The wiring method is to connect two cables to the wiring terminal and then the waterproof connector locks the wiring terminal to make waterproof, mainly for the waterproof treatment of outdoor cable communication and power interworking connection. IDC is often used to control cable waterproof connectors because of its superiority in the treatment of wire and wire harness end.Wire-to-wire waterproof connectors have plastic support parts in a variety of geometric shapes such as right-angle and round polymeric plastic parts.Most of them are mainly cylindrical, and the circular design is better for wear resistance and pressure resistance, etc., and can be waded or buried.
2. Waterproof connector for wire or cable to board.In the online waterproof connector, half of the waterproof connector is connected with wire or cable, and also connected with the printed circuit board, the same as the aforementioned wire connection, the board connection is also the same, but it needs to press or weld two connectors, its purpose is to open the cable into the electrical and electronic equipment shell for waterproof treatment, and the terminal interface is suitable for separable connectivity.With the wire-to-wire waterproof connector is much the same, the same function of the product use is not the same.
3. board to board waterproof connector.The first kind of board-to-board waterproof connector is set on the edge of the circuit board, which is called the card edge, and its development to the end will become a double-piece waterproof connector, because the technical performance of the printed circuit board and its size are growing, when the size of the board increases, the result will lead to the capacity of the waterproof connector becomes larger, thus increasing the number of terminals, and the pulling force of the waterproof connector becomes larger.The larger capacity of the printed circuit board will cause the line density to be too large, and the single-piece waterproof connector is difficult to meet its requirements, so the end will be developed into a two-piece waterproof connector.Board to board is used in more sophisticated product equipment, and the characteristics of board to board are smaller and more widely used.What are the differences between ordinary waterproof connector and aviation plug, aviation plug is a connector, aviation plug is connected to the electrical line of the electromechanical components, the specifications of the device requirements than the standard of the ordinary connector is much higher, so there is no classification, so its own electrical parameters are the first to consider the selection of aviation plug.
