Description

Technical Field

[0001] This utility model relates to the field of drawer cabinet technology, and in particular to a secondary insertion device for drawer cabinets. Background Technology

[0002] When installing and maintaining the moving parts of a drawer, it is necessary to push and pull it frequently. The moving and static plugs installed on the drawer need to be positioned relatively precisely for easy insertion. Generally, primary plugs are easier to insert and remove because their plugs are larger. However, secondary plugs have more and smaller plugs, so they need to be positioned more precisely and aligned for easy insertion. In addition, frequent pushing and pulling of the drawer can easily damage the secondary plugs.

[0003] For example, on April 13, 2016, a secondary plug-in for a low-voltage drawer cabinet with a clamping ring was disclosed, including a plug assembly and a socket assembly. The socket assembly mainly includes a socket with a socket hole. The guide post adopts a frustum-shaped guide post with a small upper surface and a large lower surface; the guide sleeve adopts a frustum-shaped guide sleeve with a large lower opening and a large upper opening. This utility model can ensure a firm connection between the plug assembly and the socket assembly, and can effectively prevent the plug contact piece from being damaged during the plugging process due to the plug contact piece lifting, thereby improving the production efficiency of enterprises. However, the applicant found that although there is a guide post, some pins and sockets are still difficult to be accurately positioned. Frequent pushing and pulling of the drawer can easily cause damage to the secondary plug-in, resulting in poor electrical contact or no contact at all, affecting the normal use of the equipment.
