Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the embodiments and with reference to the accompanying drawings.

[0013] Such as figure 1 , a DECT base power supply, the power supply shell is composed of a top shell 2 and a bottom shell 6 that are engaged with each other, and a plug 9 is arranged under the bottom shell 6 . The DECT host circuit board 3 and the switching power supply board 5 that are electrically connected to each other are fixed in the power shell, and the DECT host circuit board 3 is connected to the PABX system (automatic telephone exchange system) and converted from the audio signal of the PABX to a digitally modulated radio frequency signal, and transmission to the DECT handset and vice versa. The DECT host circuit board 3 and the switching power supply board 5 are separated into two spaces in the power supply casing by a U-shaped electromagnetic isolation plastic plate 4 in cross-section. The switching power su...

Abstract

The invention relates to wireless communication equipment and discloses a DECT (digital enhanced cordless telecommunications) base power supply. The DECT base power supply comprises a power supply housing having a plug. A DECT host circuit board and a switch power supply board which are electrically connected with each other are fixed in the power supply housing. The DECT host circuit board and the switch power supply board are separated in two spaces in the power supply housing by an electromagnetic isolation plate. An RJ11 interface which is electrically connected with the DECT host circuit board is disposed in the power supply housing. The power supply housing is further provided with a charging interface which is electrically connected with the switch power supply board. The DECT base power supply has a three-in-one function of a plug, a master and a charging base, does not need a special place for placing during use, and is convenient to use and easy to find.

Description

technical field [0001] The invention relates to wireless communication equipment, in particular to a DECT base power supply. Background technique [0002] DECT, the English full name is "Digital Enhanced Cordless Telecommunications", which is generally translated as digital enhanced cordless communication or digital enhanced wireless communication in Chinese. It is a digital communication standard and is mainly used in cordless telephone systems. DECT is the world's leading wireless standard for digital communications, featuring the best voice quality and a high degree of protection against eavesdropping. DECT's multimedia protocol standard is mainly prepared for the small office and home user market. It combines the selection of DECT data services with the optional services supported by GAP, allowing terminals to provide real integrated multimedia services including voice and data. Up to now, DECT has been widely used in digital security and monitoring equipment such as co...
