Technical Field
The invention relates to the technical field of servers, in particular to an elastic pre-tightening plugging device. The invention also relates to a plug-in connection structure.
Background
In recent years, with the increase of diversity of electronic terminal products, hardware interconnection ways inside various electronic products are increasing, and therefore, the plugging ways of various plugs and slots are increasing. Meanwhile, with the diversification of the use scenes of various terminal products, the stable connection of the plug connectors becomes a problem which must be considered in the product design process, and particularly, the stable connection of the plug connectors is particularly suitable for the hardware connection with high requirements on the connection stability. In addition, for some terminal products used in a vibration environment, a highly reliable plug connection mode becomes a key for whether the peripheral connection is normally operated for a long time.

For the snap-in connection, the connection structure is commonly used for the connection of the plug connectors inside various electronic products in the server, and the design method needs to design corresponding snaps and slots between the plugs and the slots of the plug connectors. This solution has the following problems: 1. the buckle and the clamping groove must have strict matching dimensions, if the matching dimensions are too tight, the plug can be difficult to insert and pull, and the materials are easy to fatigue; if the fit size is too loose, the locking effect of the buckle and the clamping groove is poor, the mechanical vibration influence is large, and the stability of plug connection is seriously influenced. 2. The matching mode of the buckle and the clamping groove is that the buckle and the shell are plastically packaged together in an injection mold mode generally, and if the buckle is damaged, the repair is difficult, and the maintenance cost is greatly improved.
For the bolt-nut fit connection of the plug and the slot, the scheme needs to place fixing bolts at two sides of the cable plug and design embedded nuts at two sides of the slot. This solution has the following problems: 1. the cable plug and the slot are rigidly connected. If the fastening force is too large, the cable plug is easily damaged; if the fastening force is too small, effective locking cannot be achieved, and the hidden danger of loosening exists. 2. The locking mode needs to lock the bolt and the nut in place, and the screw and the nut are time-consuming in the locking process, so that the arrangement efficiency of equipment is influenced.
Therefore, how to improve the stability of the plug-in fit between the plug and the socket and avoid the loose connection caused by the influence of vibration on the plug and the socket is a technical problem faced by those skilled in the art.
