Description
Technical field
The present invention relates to a kind of antenna that in the wireless machine of tracking exchages such as mobile phone, uses.
Background technology
In recent years, be accompanied by rapid growth for the demand of the wireless machine of tracking exchages such as mobile phone, reach the variation of services such as Word message, the desired performance of wireless machine is also little by little improved, and the thing followed is that antenna also miniaturization and, high sensitivity correspondence or the broadbandization etc. more on wireless machine are carried in expectation.
Fig. 5 is the profile that has carried the antenna in the past 6 of so wireless machine.Antenna element 1 is made by electric conducting materials such as copper wire or copper alloy plates, and forms the special coiled type of announcing in the flat 4-134906 communique of opening.The core 2 that antenna element 1 is made by insulative resins such as ABS supports, and keeps specific spacing.Below core 2, be combined with the metallic power supply connector that the below has screw thread, antenna element 1 is connected electrically on the power supply connector 3.On core 2, be installed with outward appearance good electrical conductivity sealing cap 4 as decorative element, it is made of metal or makes after plating metal on the insulative resin.The tubular outer cover of being made by insulative resins such as ABS 5 has coated the periphery of antenna element 1 and core 2, and simultaneously, its upper and lower end parts is fixedly mounted on respectively on sealing cap 4 and the power supply connector 3.Antenna 6 is in the past seen the shape that is approximate shell from the side.
In antenna 6 in the past, when the people holds wireless machine, can produce human body with static be transferred into situation on power supply connector 3 and the antenna element 1 through the circuit of wireless machine inside.At this moment, if the interval between the below part of the sealing cap 4 of the top of antenna element 1 and conductivity is narrow and small, the static that feeds antenna element 1 is transferred into core 2 and outer cover 5 at the interface, and discharges from sealing cap 4.Consequently, excessive electric current inflow might be with the damages such as IC of wireless machine inside.Therefore be necessary between the sealing cap 4 of antenna element 1 and conductivity, specific interval to be set, but this can hinder the miniaturization of antenna 6 at interval.
Summary of the invention
Antenna of the present invention has with the lower part, that is: antenna element, coat antenna element periphery insulating properties cylindrical portion, be arranged on cylindrical portion top conductivity sealing cap, be arranged on the suppressing portion that inhibition sealing cap between sealing cap and the antenna element and the static between the antenna element flow.
Although this antenna has the sealing cap of conductivity, still can protect the wireless machine that uses this antenna not to be subjected to the damage of static.

Embodiment
Fig. 1 is the profile of the antenna 16 of embodiments of the present invention.By the antenna element that forms coiled type 11 that electric conducting materials such as copper wire or copper alloy plate are made, be supported on the bar-shaped core of making by insulative resins such as ABS 12, and keep specific spacing.Be combined with the metal power supply connector 13 with screw thread in the bottom of core 12, antenna element 11 is connected electrically on the power supply connector 13.Be installed with the outward appearance good electrical conductivity sealing cap 14 as decorative element in the upper end of core 12, it is made of metal or makes after plating metal on the insulative resin.The outer cover that forms tube portion 15 that the outer peripheral portion of antenna element 11 and core 12 is made by insulative resins such as ABS covers.The upper and lower end parts of outer cover 15 is fixedly installed togather with sealing cap 14 and power supply connector 13 respectively.
On core 12, between the end 11A and sealing cap 14 above the antenna element 11, be provided with recess 12A.Be provided with protuberance 15A on the inner surface position of the outer cover corresponding with recess 12A 15, protuberance 15A is embedded among the recess 12A.Antenna 16 is seen the shape with approximate shell from the side.
Be provided with recess 12A on the core 12 between the part below end 11A above the antenna element 11 and the sealing cap 14.On the position corresponding on the inner surface of outer cover 15, be provided with protuberance 15A, and be embedded among the recess 12A with recess 12A.Utilize this structure, just can be so that between antenna element 11 and the sealing cap 14, i.e. the distance of the creeping discharge between the electroconductive component increases, thereby can avoid producing between antenna element 11 and sealing cap 14 static discharge of linearity.Protuberance 15A is that the suppressing portion as the static discharge between suppressing antenna element 11 and the sealing cap 14 plays a role.
Utilize this structure, human body with static just be difficult to flow and be sent to sealing cap 14 to antenna element 11 from power supply connector 13 through the circuit of wireless machine inside, thereby can utilize simple structure to realize having solved the high antenna 16 of good decorative property, quality electrostatic problem, that have conductivity sealing cap 14 at an easy rate.
And, because the static that flows into from sealing cap 14 is difficult to enter antenna element 11, therefore can also lower the influence of static to the circuit that is connected the Work machine on the antenna element 11.
Owing to can reduce the electrostatic influence in the antenna 16, therefore also can reduce the distance between antenna element 11 and the sealing cap 14, thereby can make antenna 16 miniaturizations.
In addition, the outer cover 15 that forms cylindrical portion can be made according to following method, and the bar-shaped core 12 that periphery has been disposed the antenna element 11 of coiled type is positioned in the shaping dies, makes after being shaped with the insulative resin insertion.Like this, because the recess 12A of core 12 and the protuberance 15A of outer cover 15 closely contact, so the path of static is blocked, thereby can prevent static discharge more reliably, at an easy rate.
Fig. 2 is the profile of other forms of antenna 23 in the execution mode.In antenna 16, just on the part in whole circumference the recess 12A of core 12 and the protuberance 15A of outer cover 15 are set.As shown in Figure 2, on the whole circumference of the outer peripheral face of core 21, recess 21A is set, and on the whole circumference of the inner peripheral surface of outer cover 22, protuberance 22A is set accordingly therewith, also can obtain same effect.
Fig. 3 is the profile of other forms of antenna 36 in the execution mode.In antenna 36, core 32 is provided with protuberance 32A, and outer cover 35 is provided with recess 35A.Protuberance 32A and recess 35A are entrenched in together, and antenna 36 has the effect identical with antenna shown in Figure 1 16.
Fig. 4 is the profile of the antenna 46 of other another form in the execution mode.In antenna 46, on core 42, be provided with recess 42A and protuberance 42B, on outer cover 45, be provided with protuberance 45A and recess 45B.Recess 42A and protuberance 45A are entrenched in together, and recess 42B and protuberance 45B are entrenched in together.Like this, because the distance of the creeping discharge of antenna element 11 and sealing cap 14 can further increase, therefore can prevent flowing of static better.
In addition, beyond the structure of above-mentioned explanation, the antenna with the static mobilization between the antenna element of the sealing cap that suppresses conductivity and conductivity also belongs to category of the present invention.The shape of antenna element or core, sheath portion is not limited to illustrated form.And the shape of the parts beyond them also is not limited to form disclosed in this invention.
