Abstract

The utility model discloses a surface adhesion non-contact type light-emittig diode (LED) numbering tube module which comprises a printed circuit board (PCB) layer, a lighting display area, a power contact, a control chip and a signal receiver, wherein the lighting display area is arranged on the upper side of the PCB layer, and the power contact, the control chip and the signal receiver are arranged on the lower side of the PCB layer. The numbering tube module removes a pin foot of an existing numbering tube, solves the problem of processing of a numbering tube surface mount technology (SMT) patch, improves working efficency, and improves generality of the numbering tube by utilizing the signal receiver and the built-in control chip.

Description

The contactless LED charactron of a kind of surface attaching type module

Technical field

The utility model relates to the contactless LED charactron of a kind of surface attaching type module, belongs to the charactron field.

Background technology

The demonstration control of existing LED charactron and signal access are finished by a plurality of PIN pin, mainly are the control of electrical property sum digit performance.The manufacturer need to carry out circuit structure design to the needs of product according to each different client, but last performance requirement all is figure place showing, therefore causes technician's quantitative change of working large, and charactron can not directly be crossed Reflow Soldering reduce production efficiency.

The utility model content

Utility model purpose: the utility model proposes the contactless LED charactron of a kind of surface attaching type module, solved charactron SMT paster treatment technology.

Technical scheme: the technical solution adopted in the utility model is the contactless LED charactron of a kind of surface attaching type module, comprise the PCB circuit layer, be positioned at the luminous display area of PCB circuit layer upside, and be positioned at power supply contact, control chip, the signal receiver of PCB circuit layer downside; Aforementioned structure all is wrapped in the ambroin shell, and wherein power supply contact partly exposes, and the display surface of luminous display area exposes.

As further improvement of the utility model, described ambroin shell is that the PPA material is made.PPA full name polyphtalamide is a kind of High Performance Insulation material of high-temperature-resistant high-pressure-resistant.

Beneficial effect: the utility model has been cancelled the PIN pin of existing charactron, has solved the difficult problem of charactron SMT paster processing, has improved work efficiency, simultaneously by using signal receiver and built-in control chip to improve the versatility of charactron.
