What should I prepare before buying circular connectors? Circular connector selection guide?

Among the many connectors, circular connectors are one of the more frequently used, which are mainly used in communications, computers, aerospace, marine and other instruments and apparatus. If we need to buy in bulk, what preparations need to be done before buying? First, determine the number of purchases If you need to buy circular connectors, you should have a clear understanding of the number of purchases, or buy less than enough, buy more than a waste of money. Different occasions and conditions of use require different quantities, to determine the number to be able to carry out the next step in the purchase. Second, do a good job in advance of the budget General business will buy in bulk, before the purchase of the general business will have a budget, budget time must be careful, although the market price of circular connectors will fluctuate, and different manufacturers to give the offer is not the same, in the budget can be based on the actual demand and the market price of the approximate budget table. Try not to exceed the budget in the actual purchase, so as to ensure that the purchase can be carried out smoothly. Third, understand the basic parameters of the needs of the current circular connector is very rich in variety, which also leads to its specifications, performance, parameters, functional performance is very different, the purchaser is to combine the actual use of the requirements to determine the general basic parameters. Circular connector purchase is not a very simple thing, from the above content can be known in many aspects of the purchase before the need to do a good job in preparation, such as determining the number of purchases, the approximate scope of the budget, the basic parameters of the product, etc., do a good job of these tasks can save you time and effort in the purchase.

When we use the circular connector, we should need to prioritize the selection of outstanding performance, connection safety, ease of use, reasonable structure and other products. Therefore, we need to consider when selecting a few elements: 1. safety parameters: to see if the product's flame retardant, there is no installation of insulation resistance, voltage performance; 2. electrical parameters: in the selection of the need to pay attention to the product's rated current, operating voltage and other parameters, and at the same time need to pay attention to the performance of its contact resistance; 3. mechanical parameters: vibration, impact, collision, mechanical life, such as separation force; 4. environmental parameters: carefully check the circular connector operating temperature range, humidity requirements, air pressure requirements, and the structure of a reasonable. 4. Environmental parameters: carefully check the operating temperature range of the circular connector, humidity requirements, air pressure requirements, sealing performance, rust resistance; 5. Termination: to understand the product is used to crimp or winding, or welding, or other connections; 6. Locking mode: the circular connector locking mode, there are many ways, threaded, in-line, bayonet, screw, etc., according to the goal of connecting the selection; 7. Installation: the use of nut type installation, or the use of flange type, is the use of cable type installation ring is welded installation; 8. Operational suitability: try to choose the adaptability of the operating space is large, and there is a connection just identification of the circular connector; 9. Dimensions, weight: circular connector specifications, dimensions, as well as the weight of a very large number of attention to differentiation; in addition to the need to comply with the actual use of the number of cores. . Circular connector selection is a lot of details and pay attention to, it is recommended that just contact the purchaser of such products to learn more about this knowledge in the procurement.
