Abstract
The utility model provides a connection scheme for a liquid crystal module and a printed circuit board, which comprises a printed circuit board provided with a rectangular hole. The display screen of the liquid crystal module is embedded into the rectangular hole of the printed circuit board. The liquid crystal module is provided with single-row pin through holes along the bottom edge thereof. One ends of single-row pins are inserted into the single-row pin through holes to be connected with the liquid crystal module, and the other ends of the single-row pins are inserted into corresponding single-row pin through holes in the printed circuit board to realize the circuit connection of the liquid crystal module with the printed circuit board. The two corners of the top of the liquid crystal module and the corresponding part of the printed circuit board are provided with combination screw through holes. Combination screws and riveted packing columns are configured to pass through the combination screw through holes to physically fixing the liquid crystal module and the printed circuit board. Due to the adoption of the above connection scheme of the utility model, the liquid crystal module is small in occupation space and firm in installation. Meanwhile, the reliability of the liquid crystal display is improved and the cost is saved to a certain degree.
Description
technical field:
The utility model relates generally to the connection scheme of a kind of liquid crystal and printed circuit board.
background technology:
Existing such as embedded board, middle-size and small-size fire alarm control unit, the products such as user profile transmitting device, nearly all to using Liquid Crystal Module as display panel, wherein such as 12864 Liquid Crystal Modules, use more, the connection scheme of existing this type of Liquid Crystal Module and printed circuit board is mainly to utilize metal connector to install from the front of printed circuit board, cause Liquid Crystal Module to exceed printed circuit board too many, install firm not, there is loose contact problem, take up room large, when there is button in printed circuit board front, just must uses higher button and add button cap, and the height of button is more high, more easily damage.
utility model content:
For solve existing and the similar Liquid Crystal Module of 12864 Liquid Crystal Module profiles install take up room large, the problems such as insecure are installed, the utility model has been to provide the connection scheme of a kind of liquid crystal and printed circuit board, this scheme has been saved the space that Liquid Crystal Module takies, and installs firmly.
The technical scheme that the utility model adopts is as follows:
The connection scheme of a kind of Liquid Crystal Module and printed circuit board, it is characterized in that: comprise printed circuit board, on described printed circuit board, offer rectangular opening, in the rectangular opening that the display screen of described Liquid Crystal Module is offered on being embedded in printed circuit board, on Liquid Crystal Module, along bottom margin, offer single contact pin via hole, this single pin holes connecting fluid crystal module is inserted in single contact pin one end, the other end inserts on printed circuit board corresponding single contact pin via hole and realizes Liquid Crystal Module and be connected with the circuit of printed circuit board, on place, two jiaos, Liquid Crystal Module top and printed circuit board, relevant position offers screw assemblies via hole, through the screw assemblies of this screw assemblies via hole and riveting dress pad post, Liquid Crystal Module and printed circuit board being carried out to physics fixes.
Described Liquid Crystal Module display screen place plane and printed circuit board place plane parallel.
Single contact pin carries out soldering after inserting single contact pin via hole.
The utility model has the advantage of:
For the Liquid Crystal Module of 12864 types provides the connection scheme of a kind of liquid crystal and printed circuit board, for the installation of liquid crystal provide a kind of take up room little, firmly scheme is installed, improved the reliability of liquid crystal display, saved certain cost.
accompanying drawing explanation:
Fig. 1 is the liquid crystal module structure vertical view of 12864 types;
Fig. 2 is the liquid crystal module structure side view of 12864 types;
Fig. 3 is single contact pin schematic diagram;
Fig. 4 is that Liquid Crystal Module is connected front view with printed circuit board;
Description of reference numerals:
Printed circuit board 1, Liquid Crystal Module 2, single contact pin 3, screw assemblies 4, riveting dress pad post 5.
Embodiment
The connection scheme of the utility model liquid crystal and printed circuit board as shown in Figure 4.On printed circuit board 1, leave single contact pin via hole, screw assemblies via hole and rectangular opening, the rectangular opening of printed circuit board 1 is slightly larger than the screen of Liquid Crystal Module 2, the display screen of Liquid Crystal Module embeds in the rectangular opening of printed circuit board, one end of single contact pin 3 is inserted to the single contact pin via hole of Liquid Crystal Module 2 from the bottom of Liquid Crystal Module 2, in the positive soldering connection of Liquid Crystal Module 2.The other end of single contact pin is inserted to the single contact pin via hole of printed circuit board 1 from the bottom of printed circuit board 1, in the front of printed circuit board 1, carry out soldering connection.The other end of Liquid Crystal Module 2 is fixed on printed circuit board 1 by screw assemblies 4 and riveting dress pad post 5, and riveting dress pad post 5, between Liquid Crystal Module 2 and printed circuit board 1, guarantees during installation that Liquid Crystal Module 2 and printed circuit board 1 are on parallel plane.
