EW-LP Series Device Connectors

The EW-LP20 series connectors are designed for high-precision, high-quality automatic insertion. With features such as self-locking device and waterproof and dustproof, it is widely used in various challenging environments.

This paper mainly introduces the concept of the connector, the basic structure, characteristics, the basic classification of the connector, and the development trend of the connector.

The connector is in more frequent contact with electrical engineers and component technicians. It is blocking in the circuit or circuit isolation, bridging communication, so that the current circuit to achieve the desired function, is an essential part of electronic devices. In the face of such an important thing, it is necessary to know some basic knowledge of it.

First, a brief introduction to what is the connector?

A connector is usually referred to as an electrical connector, which is a device that connects two active devices to transmit a current or signal. A connector in a circuit that is blocked or isolated from each other, bridging the communication to achieve the desired function of current. Connectors are an integral part of electronic devices, and one or more connectors will always be found along the current path. Connector form and structure is very different, and application objects, frequency, power, application environment, there are different connector form. For example, the connector used to light the pitch lamp is very different from the connector used to light the hard drive or the connector used to light the rocket. But no matter what kind of connector, current flow smooth, continuous, reliable is very important. It’s not just the current that’s connected through the connector. In today’s rapidly developing optoelectronic technology, the signal carrier in the optical fiber system is light, and the wires in the common circuit are replaced by glass and plastic.

In short, a connector is a device that provides quick connections and disconnections to both ends of the wire.

Second, the basic structure and characteristics of the connector

1. The basic structure parts of the connector are: contact parts; insulators; housing; accessories.

1) contact parts. Complete the electrical connection function of the core parts of the connector. Contact pairs consisting of positive and negative contacts are used to complete the electrical connection through the plugs of the negative and positive contacts.

2) insulators. Its function is to arrange the contact parts according to the required position and spacing and to ensure the insulation between the contact parts and between the contact parts and the shell. Good insulation resistance, voltage resistance, and machinability are the basic requirements for selecting insulating materials for processing into insulators.

3). Also known as the housing, the shell is the outer cover of the Harting connector, which provides mechanical protection for the internal insulation mounting plate and pins and provides alignment when plugs and sockets are plugged in, thereby securing the connector to the device.

4) accessories. The fitting divides into the structure fitting and the installment fitting. Structural accessories, such as snap ring, locating key, locating pin, guiding pin, connecting ring, cable clamp, seal, washer, etc. . Install accessories such as screws, nuts, screws, spring rings, etc…

2. Connector’s characteristic mainly manifests in the following several aspects.

1) improved manufacturing processes. Connectors simplify the assembly process of electronic products and simplify the mass production process;

2) easy to repair. If the electronic component fails, a connector is provided to quickly replace the failed component;

3) Easy to upgrade. As technology advances, when equipped with connectors can update the components, with new and better components to replace the old;

4) increased design flexibility. The use of connectors allows engineers greater flexibility in the design and integration of new products and the composition of component systems.

C. Weichat Technology mainly produces electrical connectors

It’s a major manufacturer of an electrical connector

1. Electrical connector

These connectors allow a connector with a cable to be paired with a connector on the chassis, a through-the-wall connector, or another connector with cable. It is mainly used for signal transmission between outdoor lamps and lanterns, transmission equipment bureau, all kinds of a digital program-controlled switch, internal connection of photoelectric transmission equipment and wiring rack, for data, audio, video, and other communications equipment transmission. The jacket is made of flame retardant material with a high Factor of safety. The cable adopts advanced technology products so that the cable has a good flame retardant and anti-uniformity, multi-core cable rack laying more convenient.
