Utility model content
The purpose of this utility model is to provide a kind of screw-type terminal, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of screw-type terminal, comprise terminal body and screw, one or more screw is arranged in the screw hole in the pipe portion of terminal body, and terminal body comprises pipe portion, endoporus and installation portion, and the profile of described installation portion is the combined shaped of plane and cambered surface.
As further program of the utility model: described cambered surface is the combination of the various shape of arc surface, elliptical arc surface, spline surface or more, described plane and cambered surface are smooth surface, or be provided with one or more horizontal or longitudinal convex tendon, the appearance profile line in described installation portion parting face is that camber line is connected with linear interval, and the quantity of camber line and straight line is one or more.
As the utility model further scheme: the geometric center of described installation portion and the geometric center in body tube portion are concentric, or and the center parallel in pipe portion.
As the utility model further scheme: the inside of described installation portion is solid or is provided with a counterbore.
As the utility model further scheme: the pipe portion of described terminal body and installation portion are the overall structure of same material, or more than one different materials is adopted to be formed by connecting.
As the utility model further scheme: the outer surface of described terminal body has more than one coating.
Compared with prior art, the beneficial effects of the utility model are: the feature which incorporates cylindrical, copper aluminium terminal and square copper aluminium terminal, change a wherein part for cylinder into plane, make this device general on different electric equipments, greatly reduce stock and the management cost of client, avoid the risk of misapplying terminal; No matter this device is coordinate with the plane formula of electric equipment or circular arc type syndeton, has larger contact area, electrical connection good reliability, safe to use.The installation portion of screw-type terminal is carried out miniaturization by this device, thus on electric equipment screw-type terminal can be applied in have narrow installing space, replaces the solution of original crimp type terminal, be very easy to the installation of user.
