Connecting structure for electronic cabinet backboard and connector

Abstract

The invention discloses a connecting structure for an electronic cabinet backboard and a connector. The connecting structure comprises a rectangular metal backboard and the connector, wherein the connector is a profile and comprises a connecting side, an inserting groove and a butting side; the connecting side is used for connecting a bracket; the inserting groove is arranged on the connecting side and extends in the same direction as the connecting side; the butting side is used for being butted with the inner surface of a metal panel; two cross convex hulls and a plurality of bumps are stamped on the butted surface, butted with the inner surface of the backboard, of the butting side; two cross oval countersunk holes which are matched with the cross convex hulls in a manner of one-to-one correspondence are arranged on the inner surface of the backboard; each cross convex hull is inserted into the corresponding cross oval countersunk hole; the bumps are directly butted with the inner surface of the backboard; the butting side and the inner surface of the backboard are fixed through welding of a plurality of welding spots; and the welding spots are evenly distributed along the outer edge of the butting side. The connecting structure for the electronic cabinet backboard and the connector is reasonable, convenient to assemble and suitable for electroplating.

Description

Technical field [0001] The invention relates to a connection structure between an electronic cabinet backplane and a connector. Background technique [0002] The back panel of the electronic cabinet is connected to the bracket through the connector. The connector is welded to the inner surface of the back panel of the electronic cabinet. After welding, electroplating is required. However, after the connector is welded to the back panel of the electronic cabinet, the inner surface of the back panel of the electronic cabinet closely adheres to the connector. Lean, the contact area on the inner surface of the back panel of the electronic cabinet (that is, the contact area where the inner surface of the back panel of the electronic cabinet is attached to the connector) and the connector are basically free of gaps, resulting in the pickling liquid flowing to the abutment area during electroplating It cannot be discharged, corrodes the substrate, and the appearance of the product fails...

AI Technical Summary

Problems solved by technology

[0002] The back panel of the electronic cabinet is connected to the bracket through the connector, and the connector is welded on the inner surface of the back panel of the electronic cabinet. After welding, electroplating is required, but after the connector is welded to the back panel of the electronic cabinet, the inner surface of the back panel of the electronic cabinet is closely attached to the connector Rely, the inner surface of the electronic cabinet backplane is close to the area (that is, the inner surface of the electronic cabinet backplane and the joint is close to the joint area) and the joint is basically no gap, so that the pickling solution flowing to the joint area during electroplating Unable to discharge, corrode the substrate, and the appearance of the product cannot meet customer requirements
