Abstract
The personal digital assistant with antistatic protection function includes carrier frame of metal or electroplated part as the earthing device; tough board module on the frame; and shielding metal part set on the touch board module. The shielding metal part has earthing part on the side to contact with the frame for eliminate static charge and fixing the touch board module to the frame.
Description
Technical field
The present invention relates to a kind of personal digital assistant (being called for short PDA), particularly a kind of personal digital assistant with antistatic protection function.
Background technology
The contact that the generation of static comes from two kinds of different materials with separate; when two kinds of materials contact; electronics can be from moving to another side on one side; when two separating substances; one side that electronics leaves is positively charged just, and one side of reception electronics is electronegative, hundreds thousand of/one that the electronics that moves may only account for all number of electrons; but be enough to form very big static, the dry more electrostatic phenomenon of environment is just remarkable more usually.Static discharge (being called for short ESD) effect refers to the formed electric field of electrically charged object, near the electric discharge phenomena that gas ionization produced making.Electric discharge phenomena belong to insulation breakdown, just electric discharge phenomena will take place as long as the formed electric field intensity of electrified body reaches the degree of insulation breakdown.The simple effective method that prevents static discharge is a ground connection and be connected, and the electric charge that is produced is promptly dredged.When if the object of plural static electrification is arranged, different objects can be connected with conductor and ground connection in addition, so that lower potential difference (PD) between different objects, be used for avoiding taking place between object electric discharge phenomena.
World's electronic industry is flourish these years, the portable type electronic products such as (being called for short PDA) of all kinds of notebooks of heavy demand, mobile phone and personal digital assistant on market.Meanwhile, because growth in the living standard no matter people might install air-conditioning equipment in the workplace or at home, makes humidity maintain lower level, in order to obtaining more comfortable living environment, but dry environment can cause and is difficult for the electrostatic phenomenon eliminated.Semiconductor element in electronic products such as personal digital assistant; be easy to be subjected to the influence of static; its result will cause damage to product itself; general traditional personal digital assistant only can be born the static discharge of about 10KV; therefore how to utilize the ground connection or the means of connection to increase to the Electrostatic protection ability; the destruction that the protection product is not subjected to static discharge just becomes the problem that all slip-stick artists will solve.
Summary of the invention
Given this, the purpose of this invention is to provide a kind of personal digital assistant, it has antistatic capacity preferably, can bear the static discharge of about 20KV.
This personal digital assistant with antistatic protection function comprises: the carrier that metal or plated item are made, be configured in the personal digital assistant, and as the earthing device of personal digital assistant, and also as the skeleton of personal digital assistant; Touch panel module, it is configured on the carrier; And metal screen, it is disposed on the touch panel module, and the metal screen side has grounded part, contacts with carrier, is used to make static charge dissipation, and touch panel module can be stabilized on the carrier.
For making above-mentioned purpose of the present invention, feature and advantage can more obviously be easy to understand,, and be described in detail in conjunction with the accompanying drawings below especially exemplified by a preferred embodiment.
Description of drawings
Fig. 1 is provided by the personal digital assistant synoptic diagram that provides according to a preferred embodiment of the present invention;
The vertical view of touch panel module in Fig. 2 presentation graphs 1;
The front schematic view of metal screen in Fig. 3 A presentation graphs 1;
The reverse side synoptic diagram of metal screen in Fig. 3 B presentation graphs 1.
Embodiment
With reference to Fig. 1, the personal digital assistant synoptic diagram that Fig. 1 is provided for foundation a preferred embodiment of the present invention.This personal digital assistant with antistatic protection function comprises: the carrier 110 that the plastic cement plated item is made, and it is configured in the personal digital assistant, as the grounded part of personal digital assistant, and also as the skeleton of personal digital assistant; Touch panel module 120, it is configured on the carrier 110; And metal screen 130, it is configured on the touch panel module 120, and metal screen 130 sides have grounded part 131, and it engages with anchor point 111 on the carrier 110 during assembling, in order to the dissipation static charge, and touch panel module 120 can be stabilized on the carrier 110.When the object that has high electric charge in the external environment (for example people's finger) when contacting this personal digital assistant; metal screen 130 can be dredged too much electric charge to carrier 110 by grounding parts 131 rapidly, is not subjected to the infringement of static discharge to protect inner semiconductor element.
With reference to Fig. 2, Fig. 2 is the vertical view of touch panel module 120 among Fig. 1.Touch panel module 120 comprises P.e.c. district 121 and touch face 122, P.e.c. district 121 be looped around touch face 122 around, when the personal digital assistant assembling is finished, metal screen 130 will press solidly in P.e.c. district 121, touch face 122 does not then contact with metal screen 130, and the engagement relationship by 111 of grounding parts 131 and anchor points comes firm touch panel module 120 simultaneously.
With reference to Fig. 3 A, Fig. 3 B, the pro and con synoptic diagram of metal screen 130 in their presentation graphs 1.By finding out among the figure, metal screen 130 comprises grounding parts 131 and presses solidly portion 132, and grounding parts 131 engages with anchor point 111, dredges to carrier 110 will cross multi-charge; And the rough P.e.c. district 121 that equals of the size shape that presses solidly portion 132, when the personal digital assistant assembling is finished, the reverse side that presses solidly portion 132 will press solidly in P.e.c. district 121, and the reverse side (hatched example areas shown in Fig. 3 B) that presses solidly portion 132 must be done the baking vanish processing, produces short circuit phenomenon to avoid touch panel module 120.
The personal digital assistant that the above embodiment of the present invention disclosed with antistatic protection function, static charge too much in the environment can be dredged to carrier via metal screen, antistatic capacity is increased substantially, traditional personal digital assistant can only be born the static discharge of 10KV approximately, and the present invention the experiment proved that the static discharge that can bear about 20KV.
In sum; though the present invention discloses with a preferred embodiment; but be not in order to limit the present invention; any those skilled in the art is not breaking away under the spirit and scope of the invention condition; all can make various changes and retouching, so protection scope of the present invention is defined with accompanying claims.
