Base anti-loosening connection structure and relay

The utility model discloses a base anti-loosening connection structure and a relay, the base anti-loosening connection structure comprises a base, the base comprises a false B pin assembling groove, and the back side of the false B pin assembling groove is provided with a first clamping structure; the framework is provided with a second clamping structure; the base and the framework are connected in a clamped mode through the first clamping structure and the second clamping structure so as to be used for avoiding the phenomenon that the base is loosened due to the fact that the base and the framework rotate with a line on the assembling face as the axis. According to the utility model, the first clamping structure and the second clamping structure are clamped with each other, so that the stability in the horizontal direction is kept, and the rotation taking a line on an assembly surface as an axis is avoided. 本实用新型公开了一种基座防松脱连接结构及继电器，包括：基座，所述基座包括假B脚装配槽，所述假B脚装配槽背侧设置有第一卡接结构；骨架，所述骨架设置有第二卡接结构；其中，所述基座与骨架之间通过第一卡接结构与
