Abstract
The utility model relates to a radio pager which is provided with an upper casing, a lower casing, a liquid crystal display which is arranged between the upper casing and the lower casing, a print circuit board and an antenna which is connected to the print circuit board. The pager comprises a supporting frame. Made into a rectangular shape, and matched with side frames of the upper casing and the lower casing, the supporting frame is provided with one groove and a plurality of lugs, wherein the antenna which is made into a rectangular shape is inserted in the groove inside the supporting frame, and then, the upper casing and the lower casing are connected with the supporting frame to form an integral body.
Description
The present invention relates to a kind of radio pager that is called beeper.Particularly, the present invention relates to a kind of radio pager, wherein Huan Xing antenna is installed along the frame of beep-pager shell, so that enlarge the frequency acceptance band of beep-pager, improves its receiving sensitivity.
Recently, because information transmission technique develops rapidly, at the regardless of sex or age, a lot of people utilize radio pager as commercial or individual communication instrument.Along with service range is more and more extended and expanded, this radio pager becomes and has the ability to cover the whole nation.In addition, for example subway or basement also can receive call signal even this beep-pager is in the underground space.
For receiving calling signal in high sensitivity, the importantly setting of antenna makes radio pager that the range of receiving of maximum possible can be arranged under the condition of restricted volume as portable equipment.
Yet in traditional radio pager, antenna is arranged in the narrow inner space that is made of lower casing on the beep-pager by this way, promptly constitute " " shape round a layer circuit board, so this beep-pager has covered a narrow scope and high sensitivity is not provided with its part that is arranged between the upper and lower circuit board.Therefore the shortcoming of traditional beep-pager is that receiving ability is poor, can not receive signal in this external underground space or in the wideer service area.
Therefore, the present invention is in order to eliminate one or multinomial limitation and shortcoming of this type of radio pager basically.
The purpose of this invention is to provide and a kind ofly expand the received signal frequency band and improve the radio pager accept sensitivity.
Other features and advantages of the present invention are listed in the following description, and part can maybe can be understood these feature and advantage by practice of the present invention by obviously finding out in the explanation.
The objective of the invention is to reach: the radio pager of an antenna that upper and lower shell, the LCD between them and printed circuit board (PCB) is arranged, be connected with printed circuit board (PCB) by following characteristics, comprise one that make the rectangular frame shape and match with the frame of last lower casing and have a groove to be connected the support of lug with some, wherein, the antenna of making rectangle inserts in the groove in the support, upper and lower then shell with put up integral body and couple together.
Should be pointed out that top diagrammatic illustration and following detailed description all as example and be indicative, be intended that the further instruction that the invention provides for as claimed in claim.
The accompanying drawing that is used for further understanding the present invention and is combined in specification and constitutes this specification part has been represented embodiments of the invention, and is used from explanation one and illustrates principle of the present invention.
Have in the accompanying drawings:
Fig. 1 presses the embodiments of the invention decomposition diagram, is aligned to top from below bottom;
Fig. 2 presses the perspective view of embodiments of the invention key component; And
The radio pager drawing in side sectional elevation that assembles of the line A-A of Fig. 3 described in Fig. 1 has wherein been used the present invention.
The details that relate to most preferred embodiment of the present invention now, case representation of the present invention in the accompanying drawings.
As shown in Fig. 1 to 3, radio pager of the present invention comprises a upper case 1a and a bottom shell 1b.Central authorities at lower case are shaped on display window 2, and LCD 3 usefulness fixtures 4 are fixed on the display window.Connect lug 5a and 5b and make such form, that is, they stretch out from the top edge of lower case 1b.Printed circuit board (PCB) 6 is contained among the lower case 1b, and upper case 1a is connected and covers the element of inside with lower case 1b.Especially, the present invention includes a rectangular frame shape support 7, it matches with the frame of upper and lower shell 1a and 1b between upper and lower shell 1a and 1b.Support 7 has groove 8 and is connected lug 9a and 9b.Antenna 10 is made the shape of rectangle frame and is inserted in the groove 8 of support 7, and the two ends of antenna 10 are connected on the circuit in the printed circuit board (PCB) 6 then.Upper and lower portion shell 1a is connected by being connected lug 5a, 5b, 9a and 9b mutually with 1b and support 7.
Has the antenna 10 in the groove 8 of the support that the frame of shape, insertion and the shell 1a and the 1b of straight-flanked ring matches by use, the present invention extends to the whole frame of beep-pager inside and outside shell 1a and 1b with range of receiving, and thereby has expanded frequency acceptance band and improved receiving sensitivity.
Because the present invention has expanded the frequency acceptance band to the call signal of radio call built-in antenna greatly, the receiving area is strengthened and receiving sensitivity improves, no matter therefore all can not have communication failure by receiving calling signal in large tracts of land scope place such as underground or traveling automobile.
Obviously, the technology expert can make various modifications and change to radio pager of the present invention under the situation that does not break away from the spirit or scope of the present invention.Therefore the present invention covers claims and is equivalent in the scope of claim modification of the present invention and change.
Claims (1)
1. radio pager, it has the LCD and the printed circuit board (PCB) of upper and lower shell, between and is connected antenna on the printed circuit board (PCB), it is characterized in that, support is made the shape of rectangular frame and is matched with the frame of upper and lower shell and have a groove to be connected lug with some, the antenna of making rectangular frame shape inserts in the interior groove of support, and upper and lower portion shell and support connect to form integral body then.
