Description

Communication joining device

The utility model relates to a kind of communication link, is meant that especially a kind of nationality that do not need helps any instrument, need not divest the jockey of insulated conductor; During use, make lead pass the through wires hole of insulation loam cake,, make line guarantee to fastening that lead connects reliably and install again with referring to that power pushes the insulation loam cake.

Now the jockey that uses roughly has screw bolt-type, fast three kinds of type and the envelope-style that connect.Wherein the screw bolt-type splicing ear is to be the element that continues with metal bolts, it is screwed in insulator foot form.During use, an end of metal bolts and the leading-in end or the leading-out terminal of cable join, and the wire jumper end then is wrapped on the metal bolts with the lead that divests insulating barrier, this bolt are tightened and the complete connection action again.The characteristics that though this mode has is easy to manufacture, insulation is good, but must connect just twining after the insulation displacement on the lead in advance, often cause that lead fractures because of wire stripping is improper, and use exposed bolt and lead to continue, cause corrosion easily and cause loose contact, also very easily introduce noise, influence communication quality because of the exposed bolt of human body false touch.The fast wire jumper that connects the type terminal board is to adopt to exempt from wire stripping formula (Inssulation Displacement Contact) wire jumper continues, though there is wiring quality reliable and stable, must there be the characteristics that exposed hardware causes noise again by wire stripping, but, continuing of its wire jumper must use special crimping tool to finish, usually lose because of crimping tool and use other instruments to substitute it, like this, the terminal that also makes not only with high costs is destroyed easily.The envelope-style terminal board also adopts exempts from the continuous wire jumper of wire stripping formula, has the above-mentioned fast characteristics that connect type equally; Yet,, also have the defective that must use instrument though it uses the normal screws cutter to be tool for connecting; And the terminal board of this pattern line that at every turn can only continue is right, rather than a pair of line is right, constructs loaded down with trivial details and threading is inconvenient.

The purpose of this utility model provides a kind of communication link, it can overcome the defective of above-mentioned three kinds of pattern prior aries, utilize the continue insulation loam cake of element and ingenious design of default metal, the right wire jumper of a pair of line can once be continued to be finished, both exempted the inconvenience of using special crimping tool or other instruments, also needn't divest the insulating barrier of lead in advance, continue conveniently, connect reliable and stable.

The utility model is by a base, several metals continue, and element and one insulation loam cake forms, wherein the bottom of base is a platform, the line that its upper end is provided with more than two or two is right, the right outside of this line is the cylindrical body that is provided with button hook, it is the interlocking annular groove that the center forms that its inside is provided with central protruded stigma, the bottom grooved hole of interlocking annular groove; The metal element that continues is that the one side is provided with the continual-connecting-part that distal process is up and down stretched, this continual-connecting-part is provided with vertical wire casing, be provided with therebetween extended loop laterally around the cladding sheet, make it closely to be embedded in the right interlocking annular groove of above-mentioned line, and fit with central protruded stigma; The insulation loam cake is a lid under shed, and its top is provided with instrument connection, and the continue wire casing opposite position of element of its sidewall and above-mentioned metal is provided with through wires hole, and its both side ends forms overhead kick, can be fastening with the right button hook fastening of above-mentioned line.

Following structure accompanying drawing is introduced structure of the present utility model, principle and effect in detail.
