In contacting against the origin reference location face 521 in liquid crystal display, the elastic construction for being resisted against pcb board 1, the limit for positioning conductive bar 2
Bit architecture, before the installation of locating piece 5, the distance between the elastic construction top of locating piece 5 and origin reference location face 521 are greater than installation
The spacing of pcb board 1 and liquid crystal display 3 afterwards, after the distance between remaining structure top end of locating piece 5 and origin reference location face are less than installation
The spacing of pcb board 1 and liquid crystal display 3.The liquid crystal display 3 and the limit of locating piece 5 are described to lead between interface framework 4 and pcb board 1
The electric limit of item 2 is electrically connected liquid crystal display 3 by conductive bar 2 and pcb board 1 between liquid crystal display 3 and pcb board 1.The positioning
Remaining structure of part 5 refers to other structures of the locating piece in addition to elastic construction.
The locating piece 5 includes side plate 53, and the height of side plate 53 is less than the spacing of pcb board 1 and liquid crystal display 3 after installation, such as
After this can prevent the dimension overproof (such as: the clipping room of pcb board 1 and liquid crystal display 3 is away from too small) of other parts and lever indentation,
Locating piece deformation, if excessively high, to the discontinuity of liquid crystal display or pcb board, there are risks.The elastic construction and
Position limiting structure is located at the opposite two sides of the side plate 53.In the present embodiment, the elastic construction is lever elastic swing arm 54, fixed
Before the part installation of position, one end top of the elastic swing arm 54 far from position limiting structure is the most significant end of elastic swing arm, and and origin reference location
The distance between face 521 is greater than the spacing of pcb board 1 and liquid crystal display 3 after installation.The quantity of the elastic construction elastic swing arm 54 has
Body is two (quantity of the elastic swing arm 54 is not limited to two).The one end and side plate of elastic swing arm 54 close to position limiting structure
53 are integrally connected, and the one end of elastic swing arm 54 far from position limiting structure is equipped with protrusion 541 upwards, and the top of the protrusion 541 constitutes institute
State the top of elastic construction, that is, before the installation of locating piece 5,541 top of protrusion and and the distance between origin reference location face 521
Greater than the spacing of pcb board 1 and liquid crystal display 3 after installation.In a pre-installation, each elastic swing arm 54 is in horizontality, and parallel, and
The protrusion 541 of each elastic swing arm is contour.
In the present embodiment, the locating piece 5 further includes bottom plate 52, which is located at 53 bottom of side plate, and is located at
Immediately below the elastic swing arm 54, the bottom surface of the bottom plate 52 constitutes the origin reference location face 521.
In the present embodiment, the position limiting structure is up and down and the limiting slot 51 of side opening, the conductive bar 2 insert
In the limiting slot 51, and the both ends of the short transverse of conductive bar 5 are stretched out respectively outside the upper and lower ends of limiting slot 51, and conductive bar 2 is wanted
Conduction could be carried out through overcompression, the height of conductive bar 5 is greater than the height of limiting slot 51, guarantees the short transverse of conductive bar 2
Both ends can form with pcb board 1 and liquid crystal display 3 well contact respectively.The width D of the limiting slot 51 is slightly larger than the width of conductive bar 2
Degree, the length L of the limiting slot 51 are slightly larger than the length of conductive bar 2, had not only facilitated installation, but also conducting particles accumulation is avoided to cause to lead
The low problem of the conductive reliability of electric item 2.
When installation, conductive bar 2 is inserted vertically into the limiting slot 51 of locating piece 5, liquid crystal display 3 is placed in interface framework 4
Inside bottom, the origin reference location face 521 of locating piece 5 is contacted against on the back side of liquid crystal display 3, and pcb board 1 is placed in locating piece 5
The top of elastic swing arm 54, and be pressed in liquid crystal display 2 with the locating piece 5 for being equipped with conductive bar 2 using interface framework 4 and pcb board 1
Together, assembly is completed.It should be noted that the origin reference location face 521 of locating piece arrives distance (locating piece between elastic construction top
Before installation) have to be larger than liquid crystal display 3 and 1 spacing of pcb board after installation, the top of remaining structure of locating piece and its origin reference location face
The distance between 521 are then slightly less than the spacing of pcb board 1 and liquid crystal display 3 after installation, are guaranteed effectively to fix liquid crystal display 3 and be protected with this
Shield liquid crystal display 3 is not subject to crushing.Before installation, each elastic swing arm 54 is in horizontality, after installation, the protrusion of each elastic swing arm 54
541 are pushed by pcb board 1, make elastic swing arm 54 occur elastic deformation and it is inclined.
Locating piece 5 of the invention has certain elasticity using the elastic swing arm 54 of lever type, in fixed liquid crystal display 3
Liquid crystal display 3 is protected not to be subject to crushing simultaneously.Wherein: the distance of the most significant end of the elastic swing arm 54 of locating piece to origin reference location face (
That is the maximum height H of locating piece) must than installation after liquid crystal display 3 between pcb board 1 at a distance from it is big, fixation can be played in this way
The effect of liquid crystal display 3, and there is certain elasticity to play a protective role to liquid crystal display 3；The other positions height of locating piece 5 is necessary
Be slightly less than installation after liquid crystal display 3 between pcb board 1 at a distance from it is small, be just avoided that assembling process damages liquid crystal display 3 by pressure.
Locating piece 5 has limiting slot 51 in the x direction, and conductive bar 2 is positioned by the face where the width D of limiting slot 51,
So in a z-direction, conductive bar can be moved up and down more neatly.When installing pcb board 1, since the height H of locating piece 5 is pressed
Contracting generates a power vertically downward, and by the effect of lever type elastic swing arm 54, power will be broken down into the fixed force in the direction z
With the power in the direction x, wherein the elastic force in the direction z is fixed liquid crystal display 3, and the power in the direction x pastes locating piece 5 and interface framework face 4
It is flat, between locating piece 5 and interface framework 4 gap is reduced, so that the compression of conductive bar 2 in a z-direction, will not transmit to the direction x,
Connect conductive bar 2 relatively reliable.
Above-described embodiment is only used to further illustrate a kind of time relay of the invention, but the invention is not limited to realities
Example is applied, is simply repaired to any made by structure of the locating piece in above embodiments etc. according to the technical essence of the invention
Change, equivalent variations and modification, falls within the scope of protection of technical solution of the present invention.
