Abstract
The utility model relates to a conical cylindrical screw connector that is composed of a conical-cylindrical plastic insulation outer jacket, wherein, a conical inner screw jacket is embedded in the outer jacket, and the conical inner screw jacket is a conical spring with overlapped rings. The conical spring is provided with a given elastic deformation and retraction force; when the conductor is screwed in the conical spring of the connector, the spring is spread for deformation; when the outer force is released, the retraction force of the conical spring can firmly hold the conductor, so that the conductor is uneasy to be dropped. The conical cylindrical screw connector is a simple, convenient, fast, high-efficient and practical connector, which has good contact performance.
Description
Technical field:
The utility model belongs to electrical field, particularly a kind of awl cylindricality thread electric wire connecting junction that is convenient to the connection of two leads.
Background technology:
Existing lead connects, two strands of general employings or multiply knotting form, often need use instruments such as pliers, and the lead skinner needs longer, otherwise be difficult to guarantee the reliability that connects, and also need twine insulating tape in the linkage section outside, constructing operation relative complex, the excellent conducting performance of growing man-hour and being difficult to guarantee connect.How to solve efficient and electric conductivity that existing lead connects, promptly become the utility model research object.
Summary of the invention:
The purpose of this utility model is a kind of awl cylindricality thread connector that two strands or the direct screw-in of stranded conductor can reliably can be connected of design.
Technical solutions of the utility model are achieved in that a kind of awl cylindricality thread electric wire connecting junction of being made up of awl cylindrical plastic insulating coating, and wherein at the embedded taper internal screw thread cover that is provided with of overcoat, this taper internal screw thread cover is the folded mutually volute spring of circle circle.Volute spring has certain elastic deformation and convergent force, when lead when electric wire connecting junction volute spring extruding screws in, spring produces and opens deformation, and when shedding external force, the volute spring convergent force can firmly be clamped lead, difficult drop-off.
Described volute spring is to be that the alloy lead wire circle system of rhombus forms by the cross section, and have respectively a water chestnut inwardly, a water chestnut outwardly.Because water chestnut is comparatively sharp, water chestnut outwardly can firmly embed on the insulating coating, but water chestnut insertion wire surface inwardly, perhaps when lead screws in by tapping tooth line, make more reliable that both fix, and guaranteed good electrical conductivity.
Described insulating coating inner surface is provided with internal screw thread, and volute spring dextrorotation is arranged in the insulating coating, is convenient to the screw-in of volute spring, and can revolve tighter and tighter when connecting lead.
The utlity model has characteristics reasonable in design, simple in structure, easy to operate, quick construction, provide a kind of standard component, not only connect reliably, and conduct electricity very well for lead connects.

Embodiment:
See figures.1.and.2, awl cylindricality thread electric wire connecting junction comprises that awl cylindrical plastic insulating coating 1 and the taper internal screw thread that is embedded within it overlap composition, this taper internal screw thread cover is the folded mutually volute spring 2 of circle circle, this volute spring 2 is to be that the alloy lead wire circle system of rhombus forms by the cross section, and have respectively a water chestnut 21 inwardly, a water chestnut 21 outwardly, also all have sharp tooth line inside and outside promptly, so as respectively with insulating coating 1 and lead interlock mutually, guarantee the reliability that lead connects.For this reason, also can be provided with internal screw thread at insulating coating 1 inner surface, but for volute spring 2 dextrorotations be arranged in the insulating coating 1 or insulating coating 1 inner surface convex with as Fig. 2 in vertical clamp bar 11 so that firmly be embedded mutually easilier by volute spring 2 sharp water chestnut tapping tooth lines.
Have vertical anti-skidding line 12 at described insulating coating 1 outer surface, improve skid resistance, operate so that hand is being pinched, also can be arranged with an operation ear 13 at insulating coating 1 openend for this reason, more convenient hand is grabbed and is pinched.
With reference to Fig. 3, except that being provided with of above-mentioned symmetry operation ear 13, also can be provided with an operation ear 13 and a wire clamp 14 at the insulating coating openend, operation ear 13 and wire clamp were located at insulating coating 1 openend both sides in 14 minutes, and wire clamp 14 has take-up and anti-skidding two kinds of effects.
Claims (7)
1, a kind of awl cylindricality thread electric wire connecting junction of being made up of awl cylindrical plastic insulating coating is characterized in that at the embedded taper internal screw thread cover that is provided with of overcoat, and this taper internal screw thread cover is the folded mutually volute spring of circle circle.
