Side reflection cap on offer reflection cavity, offer out optical channel on the reflection cap above the luminescence chip side, described go out light
Passage is connected with reflection cavity；On the back side of the reflection cap, interval is provided with length identical support column, the reflection cavity and
Going out in optical channel and glue-line being spread filled with epoxy resin, the reflection cap spreads glue-line with PCB also by epoxy resin
Bonding is connected.
PCB of the PCB for double-sided copper-clad.
Layer of silica gel is coated with the luminescence chip.
The beneficial effects of the utility model are：A kind of ultra-thin clock surface-mount digital tube of the present utility model, PCB
Anchor pad is also equipped with 4 angles, is easy to being welded and fixed for surface-mount digital tube, surface-mount digital tube is prevented from automation patch
There is bending in piece production；PCB of the PCB for double-sided copper-clad, strengthens the tensile strength of PCB, improves
The radiating effect of surface-mount digital tube and stability, and be prevented from the product when rivet hot is closed and bend；Above luminescence chip
Reflection cap on offer reflection cavity, offer out optical channel on the reflection cap above luminescence chip side, described go out optical channel with
Reflection cavity is connected, the light that luminescence chip sends carry out diffusing reflection in reflection cavity after again from go out optical channel injection, reflection cavity
Glue-line is spread with going out in optical channel filled with epoxy resin, it is ensured that the uniform in light emission of charactron, and reduce the thickness of reflection cap
The usage amount of glue is spread with epoxy resin, more environmentally-friendly.

Specific embodiment：
Embodiment 1
A kind of ultra-thin clock surface-mount digital tube as Figure 1-5, including PCB 1 and is arranged on PCB 1
On reflection cap 2, connection electrode 11 is installed on the both sides of the PCB 1, the connection electrode 11 passes through PCB circuits
Circuit on plate 1 is connected with the luminescence chip 3 in PCB 1, is also installed on 4 angles of the PCB 1
There is anchor pad 12.PCB 1 adopts PCB commonly used in the prior art, according to the different designs demand of product,
Diverse location that can be in PCB 1 installs multiple luminescence chips 3.Meanwhile, in PCB 1 using sheet connection
Electrode 11 replaces electrode column of the prior art, greatly reduces the thickness of charactron, and is easy to surface-mount digital tube subsequently should
The automation paster production that uses.Simultaneously reduce the thickness of reflection cap 2, can by the overall thickness of charactron drop to 2mm with
Under, and common conventional inserts formula number tube thickness about 7mm.The PCB 1 is the PCB of double-sided copper-clad, makes
The structure of PCB 1 is more stable, improves radiating effect and ability of anti-deformation.
Reflection cavity 4, the reflection cap above 3 side of the luminescence chip is offered on reflection cap 2 above the luminescence chip 3
Offer out optical channel 5 on 2, described go out optical channel 5 be connected with reflection cavity 4.The light that luminescence chip 3 sends will not directly from
Go out optical channel 5 to project, but make light more equal from going out in optical channel 5 to project again after first diffusing reflection being carried out in reflection cavity 4
Even.On the back side of the reflection cap 2, interval is provided with length identical support column 21, for keeping reflection cap 2 and PCB
Spacing between 1, protects the electronic component in PCB 1.The reflection cavity 4 be filled with optical channel 5 epoxy resin with going out
