What is the profit of the cable tray?
The positive contact is a rigid part with a cylindrical (round pin), square (square pin) or flat (insert) Positive contacts are generally made of brass and phosphor bronze The negative contact, the jack, is the key part of the contact pair It relies on the elastic structure to be elastically deformed when engaged with the pin to form a resilient force in close contact with the positive contact to complete the connection (Vertical groove), folding type (longitudinal slot, 9-shaped), box-shaped (square jack), the shape of the jack, As well as hyperbolic thread spring jack and so on Second, the shell, also known as shell (shell), is the car connector cover, it is built-in insulation mounting plate and pin to provide mechanical protection, and provide plug and socket when the alignment, and then the connector fixed To the device Third, the insulator, insulator is also often referred to as the car connector base (base) or mounting plate (insert), its role is to make the contact according to the required position and spacing, and to ensure that the contact between the contact and And the insulation between the shell Good insulation resistance, withstand voltage performance and ease of processing is the choice of insulation materials into the insulator of the basic requirements Annexes, annexes, annexes and annexes Structural accessories such as the collar, positioning keys, positioning pins, guide pins, connecting rings, cable clamps, seals, gaskets and so on Installation accessories such as screws, nuts, screws, coils and so on Accessories are mostly standard parts and common parts It is these four basic structural components to make the car connector can act as a bridge, stable operation
Generally by the positive contact and the negative contact with the composition of the pair, through the yin and yang contact to complete the electrical connection
Automotive connector four basic structural components First, the contact, is the car connector to complete the electrical connection function of the core parts
Cable bridge profit and many factors, such as steel prices, processing means, cutting technology, market demand, staff salaries, but the current general manufacturers profits can reach more than 15%. Profit is also called net profit or net income. From the narrow income, the cost, the profit includes the difference between the income and the expense, as well as other directly included in the profit and loss gains, losses. From the broad sense of income, cost, profit is the difference between income and cost. Profits according to its formation process, divided into pre-tax profits and after-tax profits. Pre-tax profit is also called the total profit; pre-tax profits minus income tax costs, that is, after-tax profits, also known as net profit.
