Description

A server PCB board power connector

technical field

The utility model relates to the technical field of server power supply connection, in particular to a server PCB board power supply connector.

Background technique

High-density servers can make full use of the computer room space. By deploying high-density servers in the computer room, the capacity of data services can be expanded under the conditions of the existing computer room.

In high-density server applications, a single server node generally needs to support hot-plug operations, and guide posts for structural positioning are usually installed on the server node. As the user's business volume increases, the load current on the motherboard side is getting larger and larger, resulting in the oversized power supply port on the motherboard side occupying too much space on the motherboard PCB. Heat dissipation in the box.

At the same time, the structure space of this density server is limited, and the traditional powerblade connector is large in size. When the conduction of large current is increasing, the powerblade connector is often limited by the structure of the chassis. Moreover, the connector is prone to slip off under the condition of long-term slight vibration, so there is a need for a power connector that is small in size, convenient to fit and not easy to fall off.

When the female head presses the pressing piece tightly against the two joint surfaces of the male and female head , the other end of the anti-detachment plate is inserted into the anti-detachment groove. When pulling out, the operator can make the anti-detachment plate detach from the female head by holding the hand pick. The structure is ingenious, and the anti-detachment can be achieved without manual operation. The purpose of the anti-drop groove matching is that it will not fall off without manual participation.

There are two anti-detachment plates, the two anti-detachment plates are respectively connected to the male head through the rotating shaft, and both sides of the female head are provided with anti-detachment grooves matching the anti-detachment hooks.

The beneficial effects of the present utility model are:

1. In practical applications, the soldering feet of the male and female headers play a fixed role, but since there are only two corresponding soldering feet, it is easy to appear when the male or female headers are attached to the corresponding PCB board. If the fit is not tight, it will warp after welding or deform during the plugging and unplugging process. Increase the positioning pin of the female head and the positioning pin of the male head to ensure the tight fit before welding and the connection after welding. Deformation during insertion and removal.

2. Both the diagonal position and the vertical position ensure the dispersion of welding stress and insertion stress. It is very good to ensure that it will not warp and deform.

3. When the male head is inserted into the female head, the mating surface of the female head presses the pressing piece, which drives the anti-separation plate to approach the female head. When it is facing, the anti-detachment hook at the other end of the anti-detachment plate is inserted into the anti-detachment groove. When pulling out, the operator can make the anti-detachment plate detach from the female head by holding the hand pick. The structure is ingenious and can be achieved without manual operation. The purpose of the anti-detachment and anti-detachment groove matching is that it will not fall off without manual participation.
