Description
Technical field
The present invention relates to a kind of electrical power wiring assembly of communication equipment, especially refer to a kind of block that is installed on the digital distribution frame.
Background technology
Development along with communication industry, high density to digital distribution frame, high power capacity is also had higher requirement, and at present, the block that is adopted on digital distribution frame is usually by panel, mounting panel and many group transducers are formed, wherein, every group of transducer is again by two first coaxial connectors, two second coaxial connectors and form with two the first h type linkers that plug with axial organ, and realize changing by the coaxial connecting line of double end of an artificial welding respectively between each first coaxial connector and corresponding second coaxial connector and be connected, as China Patent No. is a kind of block 02248445.0 the digital distribution frame of usefulness " communication " has just disclosed, panel in this block is fixed on the frame of digital distribution frame by the mounting panel of its both sides, and have the through hole of some on the panel successively, the above-mentioned coaxial connector of inserting in each through hole, and by corresponding bolts each coaxial connector and panel are fixed into one at back side of panel.Adopt the block of said structure, though can satisfy certain instructions for use, it still exists following problem: when (1) carries out installation or removal when coaxial connector on panel, all need finish by means of specific purpose tool, this makes to operate both wasted time and energy, again very inconvenience.And on the other hand, owing to be subjected to the restriction of operating space, that can not lean between every group of transducer is too near, thereby has restricted digital distribution frame to a certain extent to highdensity development.Adopt coaxial connecting line to connect between (2) two coaxial connectors, this structual shield poor performance easily causes the mutual interference of signal phase and influences communication quality.When (3) encircling certainly, need to use inconvenience with the self-loop line realization of pegging graft, and inefficiency.The inner wire socket of (4) two coaxial connectors is two lobe formula structures, and elasticity is relatively poor, causes contact unreliable and influence quality of connection easily.(5) needle tip of the inner wire contact pin of linker is very sharp again simultaneously, scratches the Gold plated Layer of inner wire socket so easily in the grafting process, and influences its further use.(6) place, finger contact site of linker body is comparatively smooth, like this in when plug, can skidding occur usually and is difficult to operation.(7) since on the panel all coaxial connector all connect by a copper coin collective, realize system earth, but when the user needs between the system mutual insulating, this earthing mode because of implicative of each other operate inconvenient.Therefore adopt the block of said structure, in use still exist many problems, so still await further raising.
Summary of the invention
Technical problem to be solved by this invention is the present situation at prior art, provides a kind of convenient for installation and maintenance and dense degree is high is used for block on the digital distribution frame.

As a further improvement on the present invention, place, the upper and lower position of described each housing can be provided with and the upper and lower card article of the unit connection diagram frame elastic fastening hook of inserting mutually, makes simple in structurely, and plug is convenient; Can certainly adopt other more common connected structure.Simultaneously on the upper and lower card article of unit connection diagram frame being provided with location hole successively for well, and be provided with at the back side of each housing and the above-mentioned location hole reference column of inserting mutually, make the location more accurately, conveniently.
As another kind of improvement the of the present invention, described first coaxial connector and second coaxial connector can be integral and realize being electrically connected with interior shielding slab crimping of establishing conductor respectively.And the appearance at this shielding slab can be provided with location notch, and corresponding inner walls is provided with the locating piece that is embedded in this location notch, so that realize assembling apace.
In described housing, can be equipped with two groups of transducers and respectively with the contacted two metal sheets of the shielding slab of each transducer, the abutting end of two metal sheets bends respectively and forms a grounding receptacle mutually, then be provided with earth jack with the corresponding back side of shell of this grounding receptacle, be convenient to the earth connection contact pin like this when inserting multiple connection, system's reliable ground is not when inserting, system's mutually insulated, can decide according to user's needs, simple to operate, flexible operation.
Improve again as of the present invention, the inner wire socket of first coaxial connector or the inner wire socket of second coaxial connector or the inner wire jack design of linker are become the pintongs structure; Needle tip with the inner wire contact pin of linker is spherical simultaneously, can avoid the needle point of contact pin to scratch the inner wire socket like this.
Be good to be provided with the raised line that increases contact friction on the body surface of described linker.In addition, also can on linker, set up monitoring holes, and be provided with in the oral area appearance of this monitoring holes and to be used for increasing finger and to touch the pattern ring of friction, occur skidding when preventing to operate.
Compared with prior art, the invention has the advantages that: after adopting said structure, each combined moving module need not screw, can freely insert or take out from card article, make installation and maintenance comparatively convenient, fast, adjacent converter is arranged more recently, so that under same frame width, can hold more transducer, thereby when improving the distributing frame dense degree, also make the two-way of linker dual purpose system connect, so the present invention need not self-loop line from ring, and has advantages of good shielding performance again, electric contact is reliable, ground connection is good, convenience operation, thereby be worth on existing digital distribution frame, applying.
