Abstract
The invention discloses a double-grounding-conductor signal transmission board which comprises a lower grounding conductor, a supporting medium, a center conductor and upper grounding conductors. The lower grounding conductor is located on the back face of the supporting medium and plays a grounding role, and when used, the lower grounding conductor makes contact with an outer transmission conductor. The center conductor is located on the front face of the supporting medium, and when used, the center conductor makes contact with an inner conductor. The upper grounding conductors are located on the front face of the supporting medium and play a role in reinforcing the grounding of the lower grounding conductor. The double-grounding-conductor signal transmission board is a printed board which is of a novel structure, is stable in performance, good in uniformity, superior in electrical performance and good in signal transmission capacity, and can meet the requirements for mass production of products.
Description
Technical field:
The present invention relates to the signal transmission board of a kind of pair of earthing conductor.
Background technology:
At present, the signal transmission board is at the microwave communication device, particularly the application in passive device is very extensive, it can carry out the transmission of microwave signal in limited space, and while using, debugging is very convenient, therefore usually be used in the transition wire transmitted as signal in cavity, in order to transmission and the performance adjustment of signal; Traditional signal transmssion line, generally adopt the structure of two-wire.As Fig. 2 A, 2B are double structure, concrete structure is ground plane 5, center conduction band 6 and dielectric 7.There are three large drawbacks in this mode: the one, and the index of product is unstable, because its ground signalling solely relies on ground plane, is transmitted, and ground plane produces oxidation after using for a long time, must cause the index of product unstable; The 2nd, transmittability is poor, due to the unification of ground plane, causes ground plane and is touched the contact resistance increase between face, thereby make voltage standing wave ratio increase, and reduces the efficiency of microwave signal; The 3rd, under production efficiency, when being produced, because the transmission of signal is obstructed, cause performance index can't reach requirement, correction, the debugging that need to carry out repeatedly just can rise to standard index by index, waste a large amount of manpowers, and scrapping of producing in debug process, the rising of production cost further aggravated.Above all drawbacks, comprehensively can bring the competitiveness of product in market low, even can't occupy market.
Summary of the invention:
For overcoming the defect of prior art, the object of the present invention is to provide the signal transmission board of a kind of pair of earthing conductor, a kind of stable performance, high conformity, electric property is superior, the signal transmission ability is good, can meet the printed board of the new structure of product mass production.
Technical solution problem of the present invention adopts following technical scheme:
The signal transmission board of a kind of pair of earthing conductor, it comprises:
The upper earthing conductors of center conductor in same plate face and two, described center conductor mediate and and described upper earthing conductor between the insulation isolation;
Also comprise lower earthing conductor and the Supporting Media between described center conductor and lower earthing conductor, described center conductor and lower earthing conductor divide front and the back side in described Supporting Media.
Design feature of the present invention also is:
Realize two-part the connection through via hole between described lower earthing conductor and upper earthing conductor.
Described lower earthing conductor, upper earthing conductor, via hole are equipped with silver-plated on the surface of conductor.
Compared with the prior art, beneficial effect of the present invention is embodied in:
Signal transmission board of the present invention, be the structure of its pair of earthing conductor, acting in conjunction, the transmission of earth signal achieves a butt joint, the main superiority of this kind of transmission means is as follows: the one, and the index of product is stable, due to the structure that adopts two earthing conductors, makes transmission board more reliable when carrying out ground connection, firmly, strengthen widely the transmittability of microwave signal, be grounded the stable transfer of signal; The 2nd, electric property is superior, the structure of two earthing conductors, and the earth resistance produced while being conducive to reduce product ground connection, reduce the voltage standing wave ratio of product further, and the microwave signal efficiency of transmission of improving product, realize the without hindrance transmission of microwave signal; The 3rd, production efficiency is high, due to the structure that has adopted two earthing conductors, when carrying out the assembling of product, product is without debugging and revising, and the disposable qualification rate of improving product, realize high efficiency production greatly, and due to without being debugged, reduce the material waste caused because of debugging, reduced the production cost of product, promoted the product cost competitiveness; Analysis-by-synthesis, because product has been used the transmission board of two earthing conductors, mechanical performance and electric property are superior, and cost also has very strong competitive advantage, must make product have very strong competitiveness on market.
The accompanying drawing explanation:
Figure 1A is overall structure schematic diagram of the present invention; The A-A cross-sectional view that Figure 1B is Figure 1A; The structural representation that Fig. 2 A is the traditional cable connector, the B-B cross-sectional view that Fig. 2 B is Fig. 2 A.
Number in the figure: 1 time earthing conductor, 2 center conductors, earthing conductor on 3,4 Supporting Medias, 41 via holes, 5 ground planes, 6 center conduction bands, 7 dielectrics.
Below pass through embodiment, and the invention will be further described by reference to the accompanying drawings.
Embodiment:
Embodiment: in conjunction with Figure 1A, 1B, the signal transmission board of two earthing conductors of the present embodiment, it comprises:
The upper earthing conductors 3 of center conductor 2 in same plate face and two, center conductor mediate and and upper earthing conductor between the insulation isolation; Also comprise lower earthing conductor 1 and the Supporting Media 4 between center conductor and lower earthing conductor, center conductor and lower earthing conductor divide front and the back side in Supporting Media.
1 pair of signal of lower earthing conductor is grounded transmitting effect, during use, with the transmission outer conductor, contacts; ; 2 pairs of signals of center conductor are realized the central transmission effect, during use, with inner wire, contact; Booster action is played in the signal transmission of 3 pairs of lower earthing conductors 1 of upper earthing conductor; Supporting Media 4, between lower earthing conductor 1 and center conductor 2, plays and supports and the impedance matching effect.
In specifically arranging, between lower earthing conductor 1 and upper earthing conductor 3, through via hole 41, realize two-part the connection.
Lower earthing conductor 1, upper earthing conductor 3, via hole 4 all adopt heavy silver-colored technology to carry out silver-plated processing to the surface of conductor, strengthen signal transmission capabilities and the transmission stability of product.
During use, the one side that the signal transmission board is provided with to lower earthing conductor 1 contacts with cavity, uses mounting screw through via hole 4, signal transmission board and cavity to be carried out fastening, is grounded the connection of signal; Center conductor 2 two ends welding at the signal transmission board need the inner wire of the components and parts of connection just can complete the application of the signal transmission board of a kind of pair of earthing conductor.
