Movable conducting structure between the signal module
Technical field
The invention relates to the conducting structure between a kind of signal module.
Background technology
The conducting structure of existing main frame and standalone module is that the terminal on the standalone module compresses the terminal on the main frame when standalone module inserts the slot of main frame, and the conducting of the signal of telecommunication has two kinds of schemes:
1. the terminal on the main frame is welded on the host circuit board, and the signal of telecommunication imports terminal on the main frame from the terminal of standalone module, imports main frame by the terminal on the main frame again;
2. the terminal on the main frame is independent of main frame, inserts the circuit board of main frame by the lead of afterbody welding, and the signal of telecommunication imports terminal on the main frame from the terminal of standalone module, imports main frame by the lead on the terminal again.
For the 1st kind of scheme, in when upgrading when maintenance, the terminal of main frame and circuit board slave unit inside need be pulled down after replacing together and set up again, this just makes the operation of upgrading become complicated relatively, has increased the cost of updating apparatus simultaneously.For the 2nd kind of scheme, though when the maintenance upgrading, need not dismantle the terminal of main frame, but because the terminal on the main frame is a movable part, the lead of terminal tails welding can have the risk of winding when normal the use, producing simultaneously needs plug wire, also need the plug line during maintenance, wasted production and maintenance man-hours, increased cost.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiencies in the prior art, and a kind of installation and maintenance and stronger signal of telecommunication conducting structure of being convenient between the signal module of versatility is provided.
The technical solution adopted for the present invention to solve the technical problems is: the movable conducting structure between this signal module comprises pedestal, conductive shaft and electroconductive elastic sheet, this conductive shaft and this pedestal form sliding pair, this shell fragment is cantilever-shaped, it has stiff end and free end, and this stiff end is positioned on this conductive shaft.
Described conductive shaft has first confined planes, and the stiff end of this shell fragment is enclosed within on this conductive shaft and the part that is locked is pressed on this first confined planes.
Described pedestal laterally is penetrated with guide hole, and this conductive shaft cooperates with this guide hole axis hole.
Described conductive shaft also has second confined planes, also is arranged with elastic component on this conductive shaft, and these elastic component two ends compress this pedestal and this second confined planes respectively.
The external diameter of described locking member and elastic component is all greater than the aperture of guide hole.
Described conductive shaft comprises first, second and third axis body that diameter increases successively, first is spacing and be the surface of first, second axis body intersection, second confined planes is the surface of second, third axis body intersection, this the second axle body cooperates with this guide hole axis hole, this electroconductive elastic sheet is enclosed within on this first axle body, and this elastic component is enclosed within on this second axle body.
The stiff end of described electroconductive elastic sheet is planar sheet, and the relative pedestal of the free end of this electroconductive elastic sheet is the arc of evagination.
The invention has the beneficial effects as follows, this activity conducting structure is an independent structures, it is realized with the Elastic Contact that is communicated with by electroconductive elastic sheet of host circuit board, do not need to use connector, make the installation and maintenance of host circuit board very independent convenient, simultaneously, convenient with different equipment particularly the volume ratio small device be communicated with host circuit board, make this conducting structure have stronger versatility.

Embodiment
See also Fig. 1 and Fig. 2, the movable conducting structure between the signal module of the present invention is to be used for two signal modules of conducting, and this signal module is used to spread out of or import into the signal of telecommunication, as the circuit board and the various independent functional units module of existing main frame.Movable conducting structure between this signal module comprises pedestal 1, conductive shaft 2, electroconductive elastic sheet 3 and elastic component 4.This pedestal 1 is provided with the guide hole 11 that laterally runs through.This conductive shaft 2 is a contact screw, this conductive shaft 2 is the syllogic multidiameter, it comprises first, second and third axis body 21,22,23 that connection in turn and diameter increase successively, the intersection of this first, second axis body 21,22 forms first confined planes 24, the intersection of this second, third axis body 22,23 forms second confined planes 25, and the diameter of this first axle body 21 is less than the aperture of guide hole 11, the aperture coupling of the diameter of the second axle body 22 and guide hole 11, the diameter of this three-axis body 23 is greater than the aperture of guide hole 11.This electroconductive elastic sheet 3 is cantilever-shaped, and it comprises stiff end 31 and free end 32, and this stiff end 31 is planar sheet, and it is provided with through hole 33, and these free end 32 relative pedestals 1 are the arc of evagination.This elastic component 4 is a spring 4.
During installation, spring 4 is enclosed within on the second axle body 22 of conductive shaft, and this conductive shaft 2 is inserted the guide hole 11 of pedestals, at this moment, this conductive shaft first, three- axis body 21,23 is in the both sides of this guide hole 11 respectively; Then, on the first axle body 21 that the stiff end 31 and the pad 5 of shell fragment is enclosed within this conductive shaft, screw with nut 6 again, thereby the stiff end 31 of this shell fragment is pressed on first confined planes 24, promptly formed the movable conducting structure between the signal module of the present invention.
During use, circuit board 7 is contained in the cavity of main frame, and makes this circuit board 7 push down the free end 32 of electroconductive elastic sheet, when standalone module 8 was unkitted into main frame, circuit board 7 slightly was pressed on the free end 32 of electroconductive elastic sheet; When standalone module 8 is packed main frame into, it promotes conductive shaft 2 to left movement and holddown spring 4, make the free end 32 of electroconductive elastic sheet be pressed on the circuit board 7 of main frame, electroconductive elastic sheet closely contacts with pad on the host circuit board, and the signal of telecommunication that spreads out of from standalone module 8 imports the circuit board 7 of main frame into by conductive shaft 2 and electroconductive elastic sheet 3.
Activity conducting structure of the present invention is designed to independent structures, it is realized with the Elastic Contact that is communicated with by electroconductive elastic sheet of host circuit board, do not need to use connector, make the installation and maintenance of host circuit board very independent convenient, simultaneously, this structural design compactness can be designed to this structure the structure of a standard, convenient with different equipment particularly the volume ratio small device be communicated with host circuit board.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the present invention is determined by claims of being submitted to.
