Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a high-density power connector. Background Art

[0002] It is used in servers / communication equipment, and in applications where the signal density is high, the product occupies a small space but the current is high; it is used in power supply PSU AC to DC, AC 3-phase or 5-phase power and other applications. While meeting the high current conditions, high-density power module and signal module design are adopted to minimize the product space as much as possible. At the same time, the product is extremely light and thin, saving customers' application space and being more conducive to the heat dissipation of the system.

[0003] When using the existing power connector, it is unable to increase the product's current carrying capacity, the pin contact is not stable enough, and the customer is required to use force to plug and unplug the power pin, which reduces the use effect of the device.

[0004] Therefore, we propose a high-density power connector to solve the above problems. Utility Model Content

[0010] Preferably, the length of the power pin contact point located at the periphery is greater than the length of the power pin contact point located near the middle position.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The number of power pin terminal pins is increased from 4 to 6, which can increase the product's current capacity. The power pin contact points are increased from the original 3 points to 5 points. The contact is more stable during customer application, which can reduce the product contact impedance and increase the product's current capacity by 30%. The first contact in the application can be used as a sacrificial contact point to meet the customer's live hot-swap application. The design of 5 points of contact can reduce the insertion force at the same time and enhance the customer's application feel.

[0013] 2. The signal adopts the structure of stamped terminal insert molding, which is convenient for assembly and production, reduces costs, and prevents high-speed signal crosstalk while ensuring product assembly accuracy; at the same time, the existing design of 5 signals / column is increased to 6 signals / column, which can increase the signal transmission density.
