Description
Technical field
The utility model relates to a kind of LED digital display screens of built-in spring.
Background technique
Touch LED digital display screen is applied in the prior art than wide.
For example, application publication number is Chinese invention patent application " the LED digital-scroll technique of drive control of CN106128321A
Screen " (application number: CN201610735562.X) disclose it is a kind of as structure.It includes pcb board, Surface-mount LED lamp, plastic cement
Shell；Pcb board includes the LED pad for the predetermined number being set on pcb board, LED pad by route on pcb board with it is general
Communication port combination hub is correspondingly connected with, and pcb board includes LED drive chip and location hole；Surface-mount LED lamp is mounted on the LED of pcb board
Pad；Plastic shell table side is provided with reflection cavity, and the corresponding LED patch in bottom accent center of each reflection cavity
Lamp, plastic shell back side is provided with positioning column, and positioning column aligns riveted with the location hole on pcb board respectively.It is general when touch
Switch is realized and the variation of capacitor is transferred on wiring board, but on existing digital display screen, finger directly touches meeting
It is inconsistent to there is a problem of that capacitor changes, causes touch function insensitive.
Therefore, it for current digital display screen, is improved up for further.
Utility model content
It can make capacitance variations for the current state of the art, the technical problem to be solved by the utility model is to provide a kind of
Transmitting more directly improve the LED digital display screen of the built-in spring of touch-sensitive.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of LED number of built-in spring is aobvious
Display screen, including shell, wiring board, capacitor board component and pad pasting, the back side of shell have installation cavity, and the wiring board is set to should
In installation cavity, the capacitor board component is set on wiring board, and the opening exposed for capacitor board group part is provided on the shell, described
Pad pasting posts in shell front and covers opening, it is characterised in that: further includes spring, the back side of shell is provided with to surround and open
The card slot of mouthful peripheral disposition, the spring is nested in opening periphery and first end and the inner bottom wall of the card slot offset, the spring
The peripheral disposition and second end for being still around capacitor board component are connected with wiring board.
In the above scheme, the shell includes substrate and the side plate that extends back around substrate edges, the substrate with
Side plate encloses the installation cavity jointly, and described to be opened on substrate, the card slot forms on the rear wall of substrate.
Preferably, it is additionally provided with the assembly set to extend back around open edge on the substrate rear wall, the assembly set
It is configured to the prism-frustum-shaped that front end is big, rear end is small, and described fills matched rear end face and the leading flank of wiring board offsets.The structure is just
In transmitting capacitor.
Preferably, the second end of the spring is mutually welded with wiring board.
Compared with the prior art, the advantages of the utility model are: the utility model is simple and reasonable for structure, in shell
Mouth periphery is provided with card slot, and is provided with while surrounding the spring of opening, capacitor board component peripheral disposition in card slot, works as people
When hand touches pad pasting, capacitance variations more directly can be passed to wiring board by spring, to improve the touch-sensitive of display screen
Property.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment；
Fig. 2 is the cross-sectional view of Fig. 1；
Fig. 3 is the exploded view of Fig. 1；
Fig. 4 is the structural schematic diagram that pad pasting is hidden in Fig. 1.
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
As shown in figures 1-4, the LED digital display screen of the built-in spring of the present embodiment includes shell 1, wiring board 2, capacitor
Board group part 3, pad pasting 4 and spring 5,1 back side of shell have installation cavity 10, and wiring board 2 is set in the installation cavity 10, capacitor board component
3 are set on wiring board 2, and the opening 111 exposed for capacitor board group part 3 is provided on shell 1, and pad pasting 4 is posted in 1 front of shell and incited somebody to action
Opening 111 covers.1 back side of shell is provided with the card slot 112 around 111 peripheral dispositions of opening, and spring 5 is nested with outside opening 111
Week and first end and the inner bottom wall of the card slot 112 offset, spring 5 be still around the peripheral disposition of capacitor board component 3 and second end and
The welding of 2 phase of wiring board.
In the present embodiment, shell 1 includes substrate 11 and the side plate 12 that extends back around 11 edge of substrate, substrate 11 with
Side plate 12 encloses above-mentioned installation cavity 10 jointly, and opening 111 is opened on substrate 11, and card slot 12 forms in the rear wall of substrate 11
On.Also, be additionally provided on 1 rear wall of substrate around opening 111 edges extend back assembly set 113, the assembly set 113 at
Shape is the prism-frustum-shaped that front end is big, rear end is small, and the leading flank of the rear end face and wiring board 2 of assembly set 113 offsets, which is conducive to
Transmit capacitor.
Using the LED digital display screen of spring built in the present embodiment, vibration can be generated when manpower touches pad pasting 4, thus
The variation of capacitor is generated, capacitance variations more directly can be passed to wiring board 2 by spring 5, to improve the touch of display screen
Sensitivity.
