The utility model solves the technical solution of the above technical problem: a kind of big line footpath conducting wire connection intermediate terminal is provided,
Including intermediate connection terminal male connector, intermediate connection terminal female and packing nut, the intermediate connection terminal male connector and it is described in
Between connection terminal female be fixedly connected by packing nut, the intermediate connection terminal male connector top be in outer circle wimble structure, and
The intermediate connection terminal male connector middle section is provided with external thread structure, the intermediate connection terminal female top is in inner circle
Wimble structure, and the intermediate connection terminal female top should do fluting design along center line, and top is divided into four symmetrical slices,
Packing nut bottom end inner wall is equipped with interior spiral shell compatible with the external thread structure of intermediate connection terminal male connector middle section
Line, and packing nut top is in outer circle wimble structure.
The technical solution that the utility model further limits are as follows:
The outer cone of the inner circle wimble structure on intermediate connection terminal female top above-mentioned and intermediate connection terminal male connector top
Structure is adapted, the angled complimentary of the angle of the angle and outer circle wimble structure of inner circle wimble structure angle.
The angle of the angle of the outer circle wimble structure on packing nut above-mentioned top and intermediate connection terminal male connector outer circle wimble structure
It spends identical, is 2 ° -6 °.
Intermediate connection terminal male connector above-mentioned and intermediate connection terminal female all use tubular conductive material.
Packing nut above-mentioned uses hexagonal bar material.
The utility model has the beneficial effects that the utility model structure is simple, in construction, the reliable of conducting wire connection is improved
Property, while flow chart is also reduced, it improves work efficiency, intermediate connection terminal female top should do fluting along center line and set
Top, is divided into four symmetrical slices, generated machinery is answered when facilitating the installation of packing nut, while can be reduced assembly again by meter
Power, it is ensured that the inner circle wimble structure of the increase of effective contact area of electric conductor, intermediate connection terminal top is connect with centre
The outer circle wimble structure on terminal top is adapted, and the angle of inner circle wimble structure angle and the angle of the angle of outer circle wimble structure are mutual
It mends, ensure that its fitness, the angle of the angle of the outer circle wimble structure on packing nut top and intermediate connection terminal outer circle wimble structure
Degree is consistent, and packing nut bottom end inner wall is equipped with and is adapted with the external thread structure of intermediate connection terminal male connector middle section
Internal screw thread, combine two terminals even closer, two such electric conductor increases effective contact area simultaneously, and stress is complete
In complete uniform situation, so that contact resistance minimizes to which calorific value also reaches minimum, operating efficiency is both improved, while
Eliminate security risk.
