Description
Technical field:
The utility model relates generally to a kind of structure of cable coaxial fitting.
Background technology:
The cable joint of prior art generally adopts securing member that the joint of cable is fixed in electrical appliance or interconnects.Cable connection to high-voltage great-current has two problems, and the one, the connection of cable outer conductor layer is firm inadequately, easily produces spark; The 2nd, cable inner conductor is not coaxial the connection with the cable outer conductor layer, and when a plurality of cables connected, the axial space that accounts for was bigger, has influenced electric performance, can not be applicable to high-voltage great-current.
The utility model content:
The purpose of this utility model is to avoid the deficiencies in the prior art part and a kind of high-voltage great-current coaxial fitting is provided.
The purpose of this utility model can be by realizing by the following technical solutions: a kind of high-voltage great-current coaxial fitting, include cable (10), its main feature is that the tip side that also includes at cable is provided with insulation adapter sleeve (5), the endoporus of one end is placed in the outside of inner insulating layer (12), the endoporus of the other end is inlaid with conduction output shaft (7), and cable inner conductor (11) is anchored in the adapter of conduction output shaft (7).The electric current of cable inner conductor (11) is by conduction output shaft (7) output.
The exposed section that described high-voltage great-current cable joint also includes outer conductor layer (13) is provided with jointing clip (8), on jointing clip (8), be fixedly connected with adapter sleeve (2), one end of its adapter sleeve (2) is provided with the shaft shoulder, clamping cap (3) is pressed on the shaft shoulder on the sleeve pipe (4) that is connected with adapter sleeve (5) outside of insulating, and is threaded with it.Jointing clip (8), adapter sleeve (2) and sleeve pipe (4) are metal, so outer conductor layer (13) is connected with outer conductor by jointing clip (8), adapter sleeve (2) and sleeve pipe (4).
The insulation adapter sleeve (5) of described high-voltage great-current cable joint is provided with bolt (6) sleeve pipe (4) that is connected.
The beneficial effects of the utility model are, cable joint adopts coaxial, overall structure, and the electric mode of connection of its uniqueness includes inner wire and is connected with outer conductor is two-part, and the insulation between the internal and external conductor.Its withstand voltage height connects reliably, and whole joint stray inductance is low, and contact resistance is little, can generally be used for being connected of all size high-pressure coaxial cable and other element.Be particularly useful in the accurate coaxial configuration of the big pulse current of high pressure.Its characteristics are as follows;
1. coaxial configuration can ensure integrally-built alignment;
2. compact conformation, succinct;
3. stray inductance and electric capacity are little, excellent electrical properties;
4. work safety, reliable;
The spiral shell buckle structure, installation and removal extremely convenient;
6. technology is simple, and material is had no special requirements.
