摘要

A connecting device of an LED(Light Emitting Diode) electric signboard is provided to facilitate installation and separation of the electric signboard and to stack easily outline frames by a first placing piece having an uneven projection and a second placing piece having an uneven groove. A connecting device of an LED(Light Emitting Diode) electric signboard is composed of an outline frame equipped with an LED board emitting the light by a control unit and a vertical connecting unit installed in the outline frame to vertically connect other outline frames. The vertical connecting unit comprises placing members(210) combined to the upper and lower sides of the outline frame and engaged with each other and a locking member(220) joined to the placing members, respectively to lock the placing members while engaging the placing members with each other. The placing member comprises a first placing piece(212) fixed on the upper side of the outline frame and provided with an uneven projection(214) and a second placing piece(216) fixed at the lower side of the outline frame and provided with an uneven groove(218) engaged with the uneven projection. The locking member is composed of a hanging projection(222) joined to a portion of the upper part of the placing member and a hanging member(230) combined to a portion of the lower part of the placing member and selectively hung to the hanging projection.
