Cable
Electronic and electrical cables & connectors, as well as its basic components, can make it more flexible when using electronic and electrical products, designing and integrating new products, and composing systems with cables, connectors, components. The basic structure of an electronic or electrical cable consists of some parts: cable, connectors, insulators, housings and accessories.
Hiedesign Cable
1. Contact parts
The contact parts of the cable and connector are the core components to complete the electronic and electrical connection function. Generally, the contact parts are composed of a male connector and a female contactor, cable, and the electrical connection is completed through the insertion of the female contactor and the male contactor.
2. Insulator
The insulator of an electronic connector is also called a base or mounting plate. Its function is to arrange the contactors according to the required position and spacing to ensure the insulation performance between the contactors and between the contactors and the shell.
3. Shell
The housing of the electronic connector, also known as the shell, is the outer cover of the electronic connector product. It provides mechanical protection for the built-in insulating mounting plate and pins, and provides alignment when the plug and receptacle are inserted, securing the electronic connector to the device.
4. Accessories
The accessories of electronic connectors are mostly standard parts and general-purpose parts, which are usually divided into two parts: structural accessories and installation accessories. The structural accessories are as follows: circlip, positioning key, positioning pin, guide pin, coupling ring, cable clamp, sealing ring, sealing gasket, etc. Screws, nuts, screws, spring coils and other accessories.
Cable Usage Trend
The use and development of connecting wires is very rapid. The safe design of the thermal management system is critical to the application of the connecting wire. The series-parallel connection between the connector and the connecting wire is an indispensable element. Its temperature rise effect is very important for the whole product.
The system has a great influence, so high-quality design has become an inevitable trend in the development of connectors and connectors.
Material requirements
The metal material is imported high-purity red copper, which has high conductivity and stable over-current temperature rise. The plastic material adopts a unique alloy material, which combines a variety of plastic properties, has both high strength and high toughness, meets fire protection requirements, and has high thermal conductivity.
Less Corrosive
Among the various types of electrical circuits, the most vulnerable to corrosion hazards are electronic connectors. The effect of corrosion on electronic connectors should not be underestimated. It gradually develops from reduced current to intermittent faults, and finally becomes more and more serious, directly causing permanent faults. Therefore, the influence of corrosion on electronic connectors cannot be ignored.
The main cause of connector failure in harsh environments is galvanic corrosion. In the current reaction, different metals release or collect electrons in the presence of an electrolyte, usually water. The ions formed by the electron transfer slowly leach from the material and dissolve it.
Although many connectors are designed for harsh environments, corrosion often shortens their life. Gaps and other leak paths (some of which are micropores) in wires, insulators, plastic housings, and pins are entry points for water and other corrosion-promoting liquids and gases.
Prevent Oxidation
Oxidation occurs when the metal of the connector combines with oxygen in the atmosphere to form a metal oxide. Most oxides are not good conductors, so an oxide coating will limit or prevent the flow of electricity.
However, leak paths in materials have many causes, and temperature cycling expands and contracts different materials at different rates. Stress conditions such as vibration or repeated bending can also open holes in the originally sealed material. Once opened, the culprit is water. In some cases, the leakage channel can be used as an absorbent core.
