Electrical outdoor-screen connecting device

Abstract

The invention discloses an electrical outdoor-screen connecting device, which comprises a display module, wherein both edges of the display module are respectively provided with an inserting slot, a control module is arranged on the display module, a wire-separating module, an integrated-control circuit board and a switching power supply are arranged in the control module, the edges of the control module are provided with plugs matched with the inserting slots, the integrated-control circuit board and the switching power supply are electrically connected with the plugs through the wire-separating module, and the plugs are preferably D-type interfaces to ensure that the control module can be correctly installed and avoid reversed installation; through the reasonable design of the connecting device, convenient and simple disassembly and assembly are realized by utilizing the integrated-designed control module through the inserting slots, so that not only is the installing efficiency greatly improved, the installation can be finished by only installing the control module on the display module through the inserting slots, the integrated control for the display module is realized by utilizing the integrated-control circuit board and the switching power supply, and an original complicated wiring process is saved, but also the electrical outdoor-screen connecting device is also easier to maintain and has a good practical value.

Description

technical field [0001] The invention relates to a connection structure, in particular to an installation structure used for electrical installation of an outdoor screen and realizing integrated installation of display modules of the outdoor screen. Background technique [0002] The use of large billboards outdoors is a common means of publicity, and with the progress of society, electronic outdoor display screens have gradually become the protagonist of outdoor advertising, referred to as outdoor screens. The outdoor screen is composed of several display modules that can be combined and spliced ​​to form a display body. Through display modules of various specifications and controllers with various combinations and different control technologies, various electronic outdoor displays can be formed to meet Different environments and requirements. Because usually more display modules are required, it is necessary to control the display module, and the control of the display modu...

AI Technical Summary

Problems solved by technology

Because usually more display modules are required, it is necessary to control the display module, and the control of the display module involves the signal control and power control of the display module. At present, the common method is to centralize the power lines of the display module. Then connect the external power supply, and connect the signal lines of the display module to the control signal part. Obviously, the installation efficiency of this connection method is low, and the connection between the power line and the signal line is confusing, and it is easy to fail during installation and use. Therefore, it is necessary to design new technologies to solve the above problems
