Description
Technical field
The utility model relates to a kind of cable antenna, relates in particular to a kind of coaxial cable antenna of wireless signal of receiving digital television specification.
Background technology
Information equipment now is towards wireless connections, as the transmission between mobile computer and network system, receive the Digital Television of wireless signal etc., bigger antenna has been not suitable for the use of this kind equipment because tradition takes up room, so coaxial cable just is widely used in field of signal transmissions.When coaxial cable during as antenna, need carry two strands of conductors of data-signal and ground signalling respectively, again coaxial cable one end be joint connector to be used for link information equipment, end then is the free end that is connected with antenna equipment in addition.
The structure of coaxial cable 10 (Coaxial cable) is to comprise that one is enclosed wire sheathing 3 (Braid) that the conduction stamen 1 (Conductor), that covers is arranged at inner insulating layer 2 peripheries, an and external insulation layer 4 (Insulation) that is arranged on braid 3 peripheries by inner insulating layer 2 (Jacket) as shown in Figure 1.The free end of coaxial cable 10 must remove the external insulation layer 4 of a length-specific, again braid 3 and inner insulating layer 2 are removed, the stamen 1 that then will conduct electricity is isolated mutually with braid 3, and conduction stamen 1 is used for the composition data holding wire, 3 of braids form the ground signalling line after twisting, aforementioned conduction stamen 1, braid 3 can combine with the external antenna seat, the structure of external antenna seat is by base shown in TaiWan, China patent announcement M270508 number, be fixed on the joint on the base, one is screwed on the rod shape antenna on the joint, one embeds the metal cap under the base, one is combined in the magnet under the metal cap, or sucker; The complex structure of this kind external antenna seat, processing procedure is complicated, relatively manufacturing cost is just very high, thus to the dealer totally unfavorable aspect the production.
In addition, about the technology of coaxial cable as antenna enforcement, can be with reference to shown in No. the 469665th, the TaiWan, China patent announcement, in the individual requests of Fig. 2 D and patent request item 10 and 18, be not difficult to find, expose the braid in it after the external insulation layer of coaxial cable one end removes: i.e. shielding layer, this braid more electrically connects with a conductor, aforementioned conductor is special angle from braid with corresponding conduction stamen, as 90 ° of extensions, in other words, conductor is to be vertical angle with exposed braid to electrically connect.
Aforesaid problem points is that the structure of traditional external antenna seat is comparatively complicated, and spare part is too much, causes manufacturing process to reach cost more and improves relatively, causes in the market that faces the product price competition now, and the electronic product of high unit price is difficult to be subjected to the consumer and accepts; In addition, the external antenna seat still takes up space, bending or folding arbitrarily, so can not take in, so be unfavorable for carrying: therefore, in view of above-mentioned, how to produce and a kind ofly can reduce manufacturing cost greatly, can be convenient to take in and portable, can keep the antenna of good reception laser propagation effect again, just become the problem points that desire of the present invention solves.
Secondly, above-mentioned coaxial cable antenna can only use the channel that receives 2.4G in fixed point, can not be as the reception of broadband signal, so can not be useful in Digital Television; And antenna is short and small, can only in build in the massaging device, can't implement as the long broadband digital television antenna of length, just become the problem points that the present invention desires to overcome so how to design one as the digital TV antenna that receives broadband signal.
The utility model content
Main purpose of the present utility model is to provide a kind of coaxial cable antenna, reduces manufacturing cost to reach, is easy to manufacture, is convenient to take in portable, can keep good reception effect to receiving broadband signal.
The utility model is to adopt following technological means to realize.
A kind of coaxial cable of coaxial cable antenna; One end is as first end that receives signal, end is second end as output signal in addition, aforementioned first end comprises one section reception conductor that has removed braid and external insulation layer, and having one after the reception conductor derives behind the braid ground connection line segment that reflexed is coated on the external insulation layer periphery by inner insulating layer is peripheral again;
One cladding is coated on the external insulation layer periphery behind the above-mentioned coaxial cable first end reception conductor, and braid is hidden interior and be in contact with it; And a connector, be connected above-mentioned coaxial cable second end and be used for any plug joint as signal output usefulness.
According to above-mentioned coaxial cable antenna, more set up one and stretch body, have the elastic stretch effect and be socketed in the resilient protection body that above-mentioned reception conductor is peripheral and the reception conductor initiatively can be stretched for a kind of.
According to above-mentioned coaxial cable antenna, an attachment that provides cladding and reception conductor to adjust angle more is provided, this attachment be a kind of can be in conjunction with above-mentioned cladding and attached to the positioner on the object plane.
The utility model compared with prior art has remarkable advantages and beneficial effect.
A kind of coaxial cable antenna of the utility model, the external insulation layer of coaxial cable first end is removed, and with braid reflexed and the exposed peripheral ground connection line segment that forms of back segment external insulation layer that is coated on, and make the end of winning have the reception conductor that receives high-frequency signals, this reception conductor length can be used to the intensity of adjusting frequency, the braid length that reflexed is coated on back segment external insulation layer periphery then has the function of the Q value of adjusting frequency, has the function that receives the wideband signal by between the two impedance matching, so can be external with Digital Television.After in addition cladding braid that reflexed is coated on back segment external insulation layer periphery is sealed, also can be with the adjustment association's frequency of shaking, and increase aesthetic appearance and reach defencive function.In the whole piece coaxial cable antenna, reception conductor and coaxial cable have splendid pliability, can crooked folding, so can be convenient to take in and carry, overcome the shortcoming that traditional rod shape antenna can not folding and is difficult for carrying.Cladding more can with attachment altogether structure combine, and attachment more can cooperate magnet, sucker or double faced adhesive tape and sorption is fixed on object plane, and can adjust angle and change the direction of reception conductor and cladding by attachment, in view of the above to reach the reception good result.At manufacture view, simple structure does not need too much antenna element, more reduces manufacturing cost simply greatly because of making, and is not reducing effect because of designs simplification aspect the signal reception; In addition, manufacturing yield of products promotes, and failure rate lowers.
