Abstract
The invention discloses an electric bridge having a waterproof function which relates to the technical field of electric bridges. The electric bridge comprises a lower cavity body, an inner cover plate and an outer cover plate, wherein the inner cover plate is installed above the lower cavity body, the outer cover plate is arranged above the inner cover plate, a waterproof groove is formed between the inner cover plate and the lower cover plate, a microstrip line is arranged in the cavity body, dielectric-slabs are respectively arranged above and below the microstrip line, and additional dielectric-slabs are respectively arranged outside the dielectric-slabs. The electric bridge having the waterproof function has high power and can enter and exit at the same time, third-order intermodulation and waterproof function can be achieved, so that functional requirements are satisfied, and the production cost is also lowered.
Description
Technical field
The present invention relates to bridge technology field.
Background technology
The frequency of now widely used 3dB electric bridge is between 800-2500MHz, along with the development of technology, require more and more higher to the communication technology, at the electric bridge of conventional 800-2500MHz frequency, coupler, power splitter, load, the passive product such as attenuator, not only use more DINd type hookup to improve power, propose three Jie's intermodulation especially, the requirement that IP65 waterproof etc. are higher, wherein electric bridge is the most obvious, propose higher high power, with entering with going out, three Jie's intermodulation, the requirements such as IP65 waterproof, if and in the electric bridge of 800-2500MHz, all realize these requirements, be difficult to realize, because require high-power, so can not microstrip design be used, the metal thickness of microstrip line only has 0.035mm, be difficult to bear high power, again because require with entering with going out, the electric bridge of conventional strip lines configuration is also not all right, and the design of column structure, possible selling price is linked to be originally all inadequate, also have three Jie's intermodulation still more, IP65 waterproof etc. requires demand fulfillment.
Summary of the invention
The object of this invention is to provide a kind of electric bridge with water-proof function, it not only power high, can with enter with going out, and can three Jie's intermodulation, can waterproof, both met needs functionally, and reduced production cost.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: it is made up of lower chamber, inner cover plate, outer cover plate, is provided with inner cover plate above lower chamber, is provided with outer cover plate above inner cover plate.
Described inner cover plate and the upper surface of lower chamber simultaneously, have individual capillary groove between inner cover plate and lower chamber.
Be provided with microstrip line in described cavity, the upper and lower of microstrip line is respectively arranged with dielectric-slab, and the outside of dielectric-slab is respectively arranged with additional agents plate, and described microstrip line includes one-level coupled zone,
Described additional agents plate is arranged on the skin of the upper and lower medium plate of position, microstrip line one-level coupled zone.
The length and width of described additional agents plate, thick difference can change in the scope of 28-34mm, 16-24mm, 4.5-5.5mm.
Described dielectric-slab thickness is 5mm.
The present invention first arranges dielectric-slab respectively at the upper and lower of microstrip line, the outside of dielectric-slab arranges additional agents plate respectively, and then this is put in the cavity of lower chamber, after adjusting position, inner cover plate is installed, with screw-driving, lower chamber and inner cover plate form tight inner chamber, the closure of whole inner chamber is good, the contact of lower chamber and cover plate is tight, three Jie's intermodulation performances of electric bridge are made to reach-150dBc, simultaneously due to after inner cover plate loads onto, its upper surface and lower chamber upper surface are simultaneously, a capillary groove is formed between inner cover plate and lower chamber, then water proof ring is put in capillary groove, install cover plate screw-driving again, like this can three Jie's intermodulation, again can waterproof.
The present invention it not only power high, can with enter with going out, and can three Jie's intermodulation, can waterproof, both met needs functionally, and reduced production cost.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
Embodiment:
With reference to Fig. 1-2, a kind of electric bridge with water-proof function, it forms 3 by lower chamber 1, inner cover plate 2, outer cover plate, is provided with inner cover plate 2 above lower chamber 1, is provided with outer cover plate 3 above inner cover plate 2.
Described inner cover plate 2 and the upper surface of lower chamber 1 simultaneously, have individual capillary groove 4 between inner cover plate 2 and lower chamber 1.
Be provided with microstrip line 5 in described lower chamber 1, the upper and lower of microstrip line 5 is respectively arranged with dielectric-slab 6, and the outside of dielectric-slab 6 is respectively arranged with additional agents plate 7, and described microstrip line 5 includes one-level coupled zone 5.1,
Described additional agents plate 7 is arranged on the skin of the upper and lower medium plate 6 of position, microstrip line 5 one-level coupled zone 5.1.
The length and width of described additional agents plate 7, be thickly respectively 30mm, 20mm, 5mm.
Described dielectric-slab 6 thickness is 5mm.
The present invention first arranges dielectric-slab respectively at the upper and lower of microstrip line, the outside of dielectric-slab arranges additional agents plate respectively, and then this is put in the cavity of lower chamber, after adjusting position, inner cover plate is installed, with screw-driving, lower chamber and inner cover plate form tight inner chamber, the closure of whole inner chamber is good, the contact of lower chamber and cover plate is tight, three Jie's intermodulation performances of electric bridge are made to reach-150dBc, simultaneously due to after inner cover plate loads onto, its upper surface and lower chamber upper surface are simultaneously, a capillary groove is formed between inner cover plate and lower chamber, then water proof ring is put in capillary groove, install cover plate screw-driving again, like this can three Jie's intermodulation, again can waterproof.
The present invention it not only power high, can with enter with going out, and can three Jie's intermodulation, can waterproof, both met needs functionally, and reduced production cost.
