The non-contact radio frequency connector comprises a transmission line section structure 1 and a coupling device 2, the transmission line section structure 1 can generate a resonance on a working frequency range, the coupling device 2 is located nearby the transmission line section structure 1, the coupling device 2 is any type of transmission line circuit structure which can couple resonance current energy on the transmission line section 1 and can not damage the resonance state of the transmission line section 1, one end 3 of a transmission line circuit of the coupling device 2 serves as an input and output port of the radio frequency connector, and the other end 4 of the transmission line circuit of the coupling device 2 can be in a open circuit state or a short-circuit state. When the connector is connected with a transmission line like a microstrip line on a coaxial cable and an equipment circuit board, mutual radio frequency signal transmission can be achieved as well among coaxial cables or other radio frequency devices under the condition that a small space interval exists among the coaxial cables or other radio frequency devices, or the coaxial cables or other radio frequency devices are isolated by not too thick unshielded medium objects.
Description
Technical field
The present invention relates to the transmission means of electromagnetic signal in the communication technical field, particularly relate to a kind of device that also can the electromagnetic signal in the close high frequency transmission line be transmitted each other without the contact of direct physics.
Background technology
For solving the bad problem of mobile communication signal in the building, adopting indoor covering system is one of present effective means, and in the construction of indoor distributed system; Usually need exterior aerial and indoor distributed system be carried out interconnecting of radiofrequency signal with coaxial cable; Therefore the exterior wall in house need be coaxial cable passed,, just interim machine drilling need be on the body of wall in house, carried out if external wall of house does not have the pre-buried passage that coaxial cable passes that can be used for; This not only can damage within doors attractive in appearance; If boring is not handled accordingly afterwards, seal that also can crime of injuries by explosive substances to buildings and goods therein makes the waterproof insect protected function reduction in room.For fear of this situation; Promptly under the situation of not damaging skin, also can make the coaxial cable of building the inside and outside carry out the radiofrequency signal transmission of interconnecting, we have invented and have not thisly needed coaxial cable internal and external conductor direct physical to contact also can to realize the noncontact radio frequency connector (see figure 1) that signal interconnects.
In addition, in use in the field of antenna, in order to improve the weatherability of antenna; Many antennas can adopt the radome of medium electromagnetic wave transparent material that antenna is carried out whole enclosed package; At this moment, in order to realize the radiofrequency signal UNICOM between antenna and the outer, coaxial cable, can on radome, leave an aperture and install corresponding radio frequency connector usually; So not only can cause destruction to a certain degree to the seal of radome; And existing dependence screw thread or inserting mode are carried out the contact type connector of mechanical connection, and itself does not possess waterproof ability; Therefore also need the docking port position to carry out water-proofing treatment afterwards, thereby make troubles for the installing engineering of setting up of entire antenna.If we adopt this noncontact radio frequency connector; Just can be under the situation of not damaging the radome seal; Accomplish the radiofrequency signal UNICOM between antenna and the outer, coaxial cable; Whole process simple and fast need not done corresponding water-proofing treatment yet, even very convenient with aft antenna maintenance dismounting yet.
Certainly, this noncontact radio frequency connector improves slightly, also may be used in the middle of the closely signal transmission of other inconvenient physics contact.
Summary of the invention
The purpose of this invention is to provide does not a kind ofly need the contact of direct physics can make the radio frequency connector that carries out radio signal transmission nearby between the transmission line, in order to solve coaxial cable carries out radio signal transmission under not contact situation problem.
The technical scheme that technical solution problem of the present invention is adopted is: a kind of transmission line section structure that can produce resonance above that; It is characterized in that; Two terminations 6 of said transmission line section 1 can be open circuit and also can be short circuit; It can also be the end terminal shortcircuit of opening a way; The transmission line form of said transmission line section 1 can be two-wire, microstrip line, the line of rabbet joint, slab guide and other any one can support the microwave transmission line pattern with Open architecture of TEM pattern electromagnetic transmission; Said transmission line section 1 can be that rectilinear form also can be a curved shape; Transmission line section 1 can be the uniform transmission line of live width size constancy; It also can be non uniform transmission line with gradual change or mutation structure size; For can support this transmission line section 1 on given operating frequency, to produce the size of wideband resonance, the length of said transmission line section 1 also can be through sealing in or the induction reactance or the capacitive reactive element of parallelly connected lumped parameter change above that according to the specific constructive form of transmission line section 1 for the length of said transmission line section 1, and said transmission line section 1 is other to have a coupling mechanism 2; Said coupling mechanism can be the transmission line circuit structure that any resonant energy on can coupled transfer line segment 1 is unlikely to destroy its resonance condition again; Distribute with the coupling line of transmission line section 1 partial parallel, one or the electric capacity of lumped parameter, one section and transmission line section 1 and transmission line that connects or the known coupled modes of other industry as one section, said coupling mechanism 2 is if one section coupling line with transmission line section 1 partial parallel, its not as the termination 4 of input/output port one end can with ground level 7 short circuits; Also can open a way, the input/output port 3 of said coupling mechanism 2 is the input/output port of this contactless connector.
The invention has the beneficial effects as follows: the invention provides a kind of device that can carry out radio signal transmission at the transmission line that does not have to make under the direct physics contact situation close; Rely on this device can make two transmission lines under the situation that does not have the physics contact, accomplish the mutual transmission of radiofrequency signal, also can make two transmission lines that separated by non-shielding dielectric spacers under the situation that spacer is not caused mechanical damage and broken ring, carry out interconnecting of radiofrequency signal.The present invention can be used in the indoor distributed system in building interconnecting of radiofrequency signal between the indoor equipment and exterior antenna; Also can be used for by the interconnecting of radiofrequency signal between airtight antenna of radome and the external cable, also can be used for various mutual isolation, sealing or be difficult to carry out to carry out radiofrequency signal between the equipment of direct physical contact and interconnect because of having relative motion relation.Occupation mode of the present invention is the both sides that spacer was placed or be fitted in to two such contactless connectors with parallel relative mode, thereby accomplishes the transmission of radiofrequency signal from one side to another side.
