Abstract
A kind of module extender board binding structure of infrared touch panel, it aims to solve the problem that in the case where touching the limited situation of screen outer casing width, the connection stitch number connected between two circuit boards is very few, the defect for causing Functional Design limited, the connection structure includes the first rigid circuit board and the second rigid circuit board, first rigid circuit board and the second rigid circuit board are limited on the same line by the frame of infrared touch panel, it further include flexible circuit board, first rigid circuit board is connected via flexible circuit board and the second rigid circuit board.The utility model is mainly used for being connected and fixed two elongated circuit boards being arranged in outer frame of infrared touch screen.
Description
Technical field
The utility model relates to multiple circuits in the plate binding structure more particularly to infrared touch panel of infrared touch panel to be linked as
The connection structure of straight line.
Background technique
Infrared touch panel passes through the development of many years, and product structure finalizes the design almost, and is all the circle electricity that gathers around liquid crystal display
Road plate has infrared emission on circuit board and receives fluorescent tube.Because being limited by board production technique, technique common at present
It is circuit board length no more than 600mm.If it exceeds this length, circuit board yields be will be greatly reduced, and chip mounter
It also can not normal patch.So common design is all to be connected two neighboring circuit board with film line 3, as shown in Figure 1.
The now this mode for connecting two plates with film line 3 has the disadvantage that: since present touch screen is for good appearance, reducing red
It is very wide cannot to be made circuit board, can only be the shape of elongate strip for the border width of outer touch screen, this just determine plate and plate it
Between the width of connector cannot be too wide, no more than the width of circuit board.And then determine the film line connected between plate and plate
It can not be too wide.General film line, the distance between adjacent line are the spacing of 0.5mm, generally accomplish 15PIN, then it is wide just
Connector be will lead to more than width of circuit board.But if limiting connecting line between plate and plate only has 15 feet, in addition it is less,
It will lead to the bad design of circuit board, in order to realize the purpose that connecting wire is few between plate plate it is necessary to giving up some property of circuit
Can, lead to the contradiction for needing to weigh performance and connector when product design.
Utility model content
To solve the above problems, the purpose of this utility model is to provide a kind of module extender board bindings of infrared touch panel
Structure improves the stitch connected between multiple rigid circuit boards in the case where outline border limited width of the structure in infrared touch panel
Quantity.
Specifically, the utility model realize above-mentioned purpose the technical solution adopted is that: a kind of module extender board of infrared touch panel
Binding structure, including the first rigid circuit board and the second rigid circuit board, first rigid circuit board and the second rigid circuit board
It on the same line by the frame limitation of infrared touch panel, further include flexible circuit board, first rigid circuit board is via soft
Property circuit board and the second rigid circuit board connection.
In some embodiments of the utility model, the flexible circuit board just beginning and end fold state is in U-typed, including the
One linking arm, the second linking arm and interconnecting piece, first linking arm and the connection of the first rigid circuit board, second linking arm
It is connected with the second rigid circuit board；The turnover structure of the flexible circuit board are as follows: first linking arm and the second linking arm point
Cloth in interconnecting piece two sides and antiparallel, first linking arm along the virtual line for passing through the interconnecting piece fold after the
One rigid circuit board and the second rigid circuit board are aligned on same straight line.
After having made improvement as above, compared to the prior art, two rigid circuit boards of connection are flexible electrical to the utility model
Road plate, the inner lead of flexible circuit board are that the modes such as etching obtain, and the interval between adjacent lines is smaller, thus in limited width
Under the conditions of can also accommodate high number of conductors；Together with the rigid circuit board is designed with flexible circuit board, it is called just
Board is disturbed, is not welded together with soldering iron.And flexible circuit board bending is good, and the first rigid electric is made after can repeatedly bending
Road plate and the second rigid circuit board are on same straight line.
Detailed description of the invention
Attached drawing 1 is that the first rigid circuit board and the second rigid circuit board are shown by the structure that film line connects in the prior art
It is intended to.
Attached drawing 2 is rigid with the first rigid circuit board and second under the utility model flexible circuit board just beginning and end fold state
The attachment structure schematic diagram of circuit board.
Attached drawing 3 is the first rigid circuit board folded status diagram of dotted line along attached drawing 2.
Attached drawing 4 is the first rigid circuit board folded status diagram of dotted line along attached drawing 3.
In attached drawing, 1 is the first rigid circuit board, and 2 be the second rigid circuit board, and 3 be film line, and 4 be flexible circuit board, 5
It is stitch for infrared discharge lamps, 6.
Specific embodiment
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing and have
The present invention is described in further detail for body embodiment.
Referring to attached drawing 2, be under the utility model flexible circuit board just beginning and end fold state with the first rigid circuit board 1 and the
The attachment structure schematic diagram of two rigid circuit boards 2.The plate binding structure includes the first rigid circuit board 1,2 and of the second rigid circuit board
Flexible circuit board 4, the first rigid circuit board 1 are connected via flexible circuit board 4 and the second rigid circuit board 2.For sake of convenience, it enables
The one side of first rigid circuit board 1 and the second rigid circuit board 2 with infrared discharge lamps 5 or infrared receiver is the face A, phase
Answering another side is the face B.
Under non-fold state, flexible circuit board 4 is in U-typed, including the first linking arm 4-1, the second linking arm 4-2 and connection
The connection of the face A of portion 4-3, the first linking arm 4-1 and the first rigid circuit board 1, the rigid circuit board and flexible circuit board
It designs together, is called and just disturbs board, not welded together with soldering iron.The second linking arm 4-2 and second is rigid
Property circuit board 2 the face A connection, when connection, 2 laid parallel of the first rigid circuit board 1 and the second rigid circuit board, and thereon
