Description
Technical field
The present invention relates to the electronic apparatus technical field, particularly a kind of light current lead jointing device.
Background technology
Along with social progress, technology such as television digitization signal, monitoring, medical treatment, broadband, temperature control, multimedia, intelligence transmission constantly are applied, concentric conductor is then adopted in the connection during these technology are used, that is: the light current lead.Because the signal source of above-mentioned technical equipment itself is just very weak, thereby signal is very easily decayed in transmission course, particularly when joint wherein being housed extending transmission distance, its signal attenuation is more, has a strong impact on the normal use of equipment.Therefore, it is higher to be used for the quality requirement of the joint that above-mentioned light current lead prolongs.In the prior art, the joint that is used for above-mentioned light current lead is more, as being connected of television signal line and branch distributor, be that television signal line middle signal line (that is: single strand of copper wire) is inserted in the metal intermediate plate of branch distributor input and output joint, outside fastening nut, the fixedly outer field shielding conductor of television signal line.The weak point of this joint is: the one, and contact area is little, causes resistance big, and electric current is little, and the TV signal decay is big; The 2nd, connect insecurely, loosening easily oxidation causes TV image fuzzy, the color dimness.Also has a kind of joint, be that the screw rod and the branch distributor housing of hollow is affixed, at the screw rod hollow space insulating part is set, at the insulating part hollow bulb binding post is set, this binding post lead is connected with the circuit of branch distributor, binding post outward the end face central authorities of an end access opening that inserts for holding wire is set, plane central authorities are provided with little screw hole on binding post, the signal single strand of copper wire is passed nut central authorities, fix with screw rod after inserting access opening, connect again nut tighten the envelope cover screw rod, though this joint can be realized firm connection, weak point is that its fitting operation is cumbersome.
Summary of the invention
At the existing deficiency of existing product, technical problem to be solved by this invention provide a kind of fitting operation convenient and swift, be connected firmly and the unattenuated light current lead of level signal and the jointing device of electrical equipment or light current lead and light current lead.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is a kind of light current lead jointing device of invention: comprise lead introducing cone 8, nut sleeve 7 and screw rod cover 2, also include inner conical drogue 5, inner conical drogue cave 6, isolated tube 3 and lead dop 4; Lead is introduced cone 8 and is threaded onto in the nut sleeve 7, goes back suit inner conical drogue cave 6 in the nut sleeve 7, and inner conical drogue 5 is loaded in the inner conical drogue cave 6; Lead dop 4 is threaded onto in the isolated tube 3, is threaded onto together in the screw rod cover 2; Screw rod cover 2 is threaded onto in the nut sleeve 7, and lead dop 4 is threaded onto in the inner conical drogue 5.
The upper end of lead dop 4 is provided with taper dop 13, has wire through-hole 15 in the centre of this taper dop 13; In taper dop 13, have two or more retraction slot 14.
Also be provided with same taper dop 13 in the lower end of lead dop, constitute both-end taper lead dop 4`.
Light current lead jointing device of the present invention, employing has the mode that the taper lead dop of retraction slot cooperates with inner conical drogue, when taper lead dop stretches into inner conical drogue, taper lead dop can shrink, its inner cylinder face can block the holding wire of lead firmly, realize firmly connecting, prevent the decay of level signal; Simultaneously, during operation, only need screw nut sleeve and get final product, so fitting operation is convenient and swift; In addition, the shielding conductor of wire external layer is introduced cone, nut sleeve and screw rod cover by lead and is fused, and has formed the shielding to holding wire in the middle of it, can effectively prevent electromagenetic wave radiation.Therefore, the present invention compares with existing like product: have characteristics such as install that faster, the more difficult decay of signal, reception are better, sound and image are more clear.

Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
Embodiment one:
Present embodiment is used for being connected of lead and electric equipment, introduces cone 8, nut sleeve 7 and screw rod cover 2, inner conical drogue 5, inner conical drogue cave 6, isolated tube 3 and lead dop 4 by lead and constitutes, and sees that 1 in accompanying drawing is not.
It is that a top is the cylinder that taper, bottom have double step that lead is introduced cone 8, and its upper taper partly is used to install conductor shielding line and lead external insulation layer, and by the location of topping bar; Its location when being used to install nut sleeve 7 of getting out of a predicament or an embarrassing situation.
Nut sleeve 7 is the nuts that have inner stopper, and lead is introduced cone 8 and penetrated from bottom to top, and it is got out of a predicament or an embarrassing situation and is positioned the inner stopper of nut sleeve 7.
Inner conical drogue cave 6 is oblate cylinders that have step through-hole; Inner conical drogue 5 is a cylinder, and its endoporus is back taper; The upper end of inner conical drogue 5 is threaded onto in the stepped hole in inner conical drogue cave 6.Inner conical drogue cave 6 is the macromolecule insulating material of anti-electromagnetic radiation, and inner conical drogue 5 is a metal material.
The tube that isolated tube 3 is made for the insulating polymeric material of anti-electromagnetic radiation; Screw rod cover 2 is made for metal material, and its outer cylinder is threaded, and the internal thread of the nut sleeve made from metal material 7 is supporting, and its centre is a through hole.
All parts of the present invention except that indicate adopting that insulating material makes, are non-insulating material and make.
During installation, the lower end of lead dop 4 is fixed on the electric equipment 1 (receive or output is connected) with the internal signal of this electric equipment 1, its external cylindrical surface suit isolated tube 3, behind the through hole suit isolated tube 3 in the middle of the screw rod cover 2, also be fixed on electric equipment 1 on (being connected) with the casing of this electric equipment 1.
During use, earlier lead inner insulating layer 12 is removed suitable part, then, the position, cone upper end that lead is introduced cone 8 by lead is inserted, allowing conductor shielding line 10 and lead external insulation layer 11 be enclosed within lead introduces on the cone of cone 8, and allow conductor signal lines 9 insert in the wire through-hole 15 of lead dops 4 centres, at this moment, can screw nut sleeve 7.In screwing process, the taper dop 13 on lead dop 4 tops can progress in the back taper endoporus of inner conical drogue 5, owing to have retraction slot 14 on the taper dop 13, thereby under the extruding of back taper endoporus, taper dop 13 can shrink to the centre gradually, thereby, the inner cylinder face of taper dop 13 blocks conductor signal lines 9 firmly, forms firmly to connect, and it is made moist be difficult for oxidation, loosening and disconnection.
Embodiment two:
Present embodiment is a special case of the present invention, be used for being connected of lead and lead, by two leads introduce cones 8, two nut sleeve 7 and screw rod cover 2`, two inner conical drogues 5, two inner conical drogue caves 6, isolated tube 3` and lead dop 4` constitute, that is: on the basis of embodiment one, increase by a cover embodiment one symmetrically, see shown in the accompanying drawing 2.Its using method and embodiment one are basic identical, according to the using method of embodiment one, fix an end lead earlier that is:, and then, according to the using method of embodiment one, fixedly other end lead gets final product again again.
Light current lead jointing device of the present invention can be widely used in the input and output of weak current equipments such as video, radio frequency, audio frequency, monitoring, medical treatment, broadband, temperature control, multimedia, intelligence transmission and the connection between the light current lead.
