Abstract
The utility model provides a waterproof connection structure for an LED display screen. The structure includes at least two LED display module groups and a signal transmission plate, wherein, the signal transmission plate is connected between the at least two LED display module groups. Each LED display module group comprises a framework and a lamp plate which is nested into the framework. The two frame rims, the framework corresponded to, are provided with signal transmission holes, and each signal transmission hole is arranged with a connecting piece sleeved with a waterproof rubber ring. The signal transmission plate includes a rear cover plate and a concatenating printed circuit board(PCB), by means of the unique design, the communication between the display signal of the at least two LED module groups and the power supply is realized via the concatenating printed circuit board(PCB), moreover, the integral waterproofing effect for the display screen is realized by means of the waterproof rubber rings between the rear cover plate and LED display module groups to fill the gap resulting from the splicing of two LED display module groups.
Description
Technical field
The utility model relates to a kind of waterproof construction, more specifically is meant the waterproof connecting structure of LED display.
Background technology
Along with science and technology development, constantly ripe as the application means of the LED of light-emitting component, the technology of utilizing LED to make display screen has now obtained development rapidly.LED display is widely used in stadiums, city and public square, traffic, corporate image propaganda, commercial advertisement and other application now.Because the stadiums viewing distance is far away, ambient brightness is high, has only LED display could satisfy this specific (special) requirements, guarantees that spectators obtain clear, distinct coloured image, for spectators bring unlimited visual enjoyment.In public places, the indoor and outdoor LED display shows social information and various dynamic picture, allows people feel that at any time the pulsation of society beats.As one of best image information approach of public traffic information, LED display also will be on the airport, give full play to one's skill in railway station, highway, subway, districts and cities' light rail etc.As the full color display of oversize, super brightness, LED in the street corner, commercial square, pile, park, shopping center become the important selection of commercial advertisement.
Conventional LED display is to show that by a plurality of LED module is spliced, these LED show that the shows signal joint between the module interconnects by winding displacement, power connection also is connected with each other by power lead, because common LED shows module waterproof fully itself, must rely on casing to come waterproof, obviously after numerous LED showed that module is put into casing together, LED showed one of problem that is connected to become the puzzlement engineering staff between the module.And these LED demonstration modules realize that by winding displacement and power lead the transmission manner of signal and power supply does not have waterproof effect.
Summary of the invention
The utility model provides the waterproof connecting structure of LED display, it realizes that by cascade PCB at least two LED show the shows signal of module and being interconnected of power supply, and show that by this bonnet shrouding and LED the waterproof apron between the module fills up the slit that two LED show that modules splicing back forms, realize the effect of display screen integral waterproofing.And this is to be first purpose of the present utility model.
Second purpose of the present utility model is to provide a kind of manufacturing simple, the waterproof connecting structure of the LED display of low production cost.
The technical solution adopted in the utility model is: the waterproof connecting structure of LED display, comprise that at least two LED show module and signal transmission board, wherein, this signal transmission board is connected these at least two LED and shows between the module, each LED shows that module comprises framework and the lamp plate that is connected to form by four edges, this lamp plate is embedded in this framework, two edges of this framework correspondence offer the signal transmission hole, each signal transmission hole all is equipped with web member, this web member is arranged with waterproof apron, this signal transmission board comprises bonnet shrouding and cascade pcb board, wherein, show that with each LED the lamp plate of module is electrically connected in the transmission hole of each LED demonstration module of this cascade pcb board cross-under, this bonnet shrouding is to should the cross-under of cascade pcb board showing in the transmission hole of module at each LED, and this bonnet shrouding all shows that with each LED the waterproof apron of module contacts.
This cascade pcb board is provided with signal aviation head and power supply aviation head,
The beneficial effects of the utility model are, the utility model comprises that structurally at least two LED show module and signal transmission board, wherein, this signal transmission board is connected these at least two LED and shows between the module, each LED shows that module comprises framework and the lamp plate that is connected to form by four edges, this lamp plate is embedded in this framework, two edges of this framework correspondence offer the signal transmission hole, each signal transmission hole all is equipped with web member, this web member is arranged with waterproof apron, this signal transmission board comprises bonnet shrouding and cascade pcb board, wherein, show that with each LED the lamp plate of module is electrically connected in the transmission hole of each LED demonstration module of this cascade pcb board cross-under, this bonnet shrouding is to should the cross-under of cascade pcb board showing in the transmission hole of module at each LED, and this bonnet shrouding all shows that with each LED the waterproof apron of module contacts.By its special structure design, it realizes that by cascade PCB at least two LED show the shows signal of module and being interconnected of power supply, and show that by this bonnet shrouding and LED the waterproof apron between the module fills up the slit that two LED show that modules splicing back forms, realize the effect of display screen integral waterproofing
