Abstract
The invention discloses a card type wireless positioning terminal with a shielding frame and an adhesive reducing concave groove. A casing structure mainly consists of a wireless positioning terminal lower cover, a wireless positioning terminal upper cover and a PCB (printed circuit board), wherein the PCB is arranged between the wireless positioning terminal lower cover and the wireless positioning terminal upper cover. The casing structure has the advantages that 1, the metal shielding frame is additionally arranged, so the communication quality is improved; and 2, the avoidance design of the position of the adhesive reducing concave groove is adopted, so the integral thickness of the casing structure is effectively reduced.
Description
Technical field
The present invention relates to wireless positioning terminal, specifically refer to mask frame and have a card type wireless positioning terminal shell structure that subtracts the glue groove.
Background technology
In the existing wireless positioning terminal, comprise upper and lower casing, and the PCB circuit board that is arranged between the upper and lower casing consists of.
Wherein, the electronic component of PCB circuit board all exposes outside, does not take any safeguard procedures.Therefore for important electronic chip, need to make special protection to electromagnetic compatibility and electromagnetic interference, generally need to around electronic chip, increase the metallic shield frame, adopt the metallic shield mask to protect important electronic chip, prevent that with this signal electromagnet from disturbing.Increase communication quality.
Upper shell is directly above the metallic shield frame in the common product, and and the metallic shield frame between keep certain interval (0.1 ~ 0.2mm).Therefore after having increased the metallic shield frame, the integral thickness that can produce wireless positioning terminal increases.Under some special dimensional requirement, most products can abandon the use of metallic shield frame, satisfy size requirements with this.Therefore the communication quality that can produce wireless positioning terminal reduces greatly.
Based on foregoing, we can find out, increasing the metallic shield frame and keeping between these two kinds of demands of communication quality, exist larger contradiction, and we know that after having increased the metallic shield frame, wireless positioning terminal will certainly increase certain thickness.
Therefore, based on above-mentioned contradiction, we need a kind of, both can increase the metallic shield frame and ensure communication quality, do not need again to increase the structure of the general thickness of wireless positioning terminal.
Summary of the invention
The object of the present invention is to provide a kind of simple in structurely, can increase the metallic shield frame, can effectively dwindle the product integral thickness with mask frame and have the card type wireless positioning terminal that subtracts the glue groove.
Implementation of the present invention is as follows: with mask frame with have a card type wireless positioning terminal shell structure that subtracts the glue groove, mainly consisted of by the wireless positioning terminal lower cover that sets gradually from top to bottom, PCB circuit board, wireless positioning terminal loam cake, the PCB circuit board comprises the metallic shield frame all around that is arranged on the electronic chip on the PCB circuit board and is arranged on electronic chip, and the metallic shield frame is connected with the PCB circuit board; Described wireless positioning terminal loam cake is provided with and subtracts the glue groove, subtract the glue groove be positioned at the metallic shield frame directly over, and described metallic shield frame is arranged on away from the one side of PCB circuit board and subtracts the glue inside grooves; Described wireless positioning terminal loam cake is embedded with copper coin, and described copper coin is positioned at directly over the metallic shield frame, and is provided with the thermal grease layer between copper coin one side and the metallic shield frame.
Described metallic shield frame is that 0mm is to 0.05mm away from the one side of PCB circuit board and the distance that subtracts between the bottom surface of glue groove; The thickness of copper coin is 5mm.
Described metallic shield frame is parallel to have the heat radiation through hole with the one side PCB circuit board.
Based on foregoing, can find out, the present invention is set with the metallic shield frame at the electronic chip of PCB circuit board, so the thickness of the wireless positioning terminal of the present invention's design will increase, therefore, in order to solve the thickness problem of wireless positioning terminal, the present invention is at wireless positioning terminal loam cake place, be positioned at the metallic shield frame directly over the position, employing subtracts the method for glue, and digging has the glue of subtracting groove.And the metallic shield frame is arranged on subtracts the glue inside grooves.
In order to dispel the heat, the metallic shield frame has the heat radiation through hole, for good heat dissipation effect, so the metallic shield frame and subtract distance between the bottom of glue groove be 0mm between the 0.05mm have the slit so that subtract between the bottom of glue groove and the metallic shield frame.Certainly, for the thickness problem of further less wireless positioning terminal, the metallic shield frame can be set touch with the bottom connection that subtracts the glue groove.Can also apply one deck thermal grease layer at the metallic shield frame simultaneously.
Therefore based on foregoing, we can find out.The present invention utilizes the thickness of wireless positioning terminal loam cake, and groove is set, and keeps away the position design with this position of making the metallic shield frame and satisfies the demand that thickness reduces.
The invention has the advantages that: 1, increase the metallic shield frame and improve communication quality; 2, adopt the position that subtracts the glue groove to keep away the position design, effectively dwindle the product integral thickness.
