Technical field
The present invention relates to electric wire connection fittings, is a kind of power line connector for box internal wiring specifically.
Background technology
Power line terminal box connects the narrow space stayed usually to power line; and common connection operating environment is poor; in stuffy sultry indoor; outdoor faces again burning sun severe cold; especially, the usual hardness of power line is comparatively large, is connected by hard power line limited for bending leeway in narrow and small terminal box with tiny screw terminal; usually can make the screw stripped thread of binding post due to the bending stress of power line, or cause and settle not in place due to hard power line and cause loose contact.Example the most common is, power circuit is all embedded in metope by interior decoration, seem more attractive in appearance and easy to clean to make indoor wall, in order to ensure that use can not excess load, the power line of current indoor generally employs the pure copper wire of area of section more than 4 ~ 6 square millimeters, and the homeplug powerline of 6 square millimeters is very general.But, the switch panel terminal box small and exquisite relative to exquisiteness, the power line large with hardness single hard conductor naked reliable connection thing connect end also becomes the general problems faced of upfitter, and the naked end that connects of thicker electric power single hard conductor more exists with the connection of switch panel the problem connecting difficulty, loose contact, inaccurate, the easy damage panel in installation site.
Summary of the invention
Technical problem to be solved by this invention solves the problem, and provides a kind of power line connector for box internal wiring, makes the naked end that connects of the large electric power of hardness single hard conductor become easily reliable with the connection of panel.
The described power line connector for box internal wiring, for being connected auxiliary to hard power rail and power terminals in enclosed box body, it is characterized in that: comprise contact link and the end of a thread link, connect the compliant conductive connector that described contact link and described the end of a thread link are provided with outer insulating layer coating, carry out conduction connect for eliminating the bending stress of hard power rail;
Described contact link connects the naked one end connecing end and compliant conductive connector of single hard conductor by fixture and forms; Described the end of a thread link comprises overcoat activity and crimps the connection pawl buckled, the afterbody of described connection pawl connects the other end of compliant conductive connector by fixture, described activity crimping button be used for by with is connected being threaded between pawl and tightens up the front end connecting pawl, described compliant conductive connector, fixture and the movable outer surface detained that crimps all are coated with insulating barrier.
Further, described connection pawl is provided with the multichip connection calvus that afterbody is connected as a single entity, and connects between calvus and offers calvus space vertically, and the outer surface connecting pawl entirety is provided with and connects pawl external screw thread.
A kind of prioritization scheme is that the front end of described connection pawl is drawn in center, and space is left at center, and the madial wall connecting pawl is provided with Contact Tooth.
A kind of prioritization scheme is, described activity crimping button is for tubular, and madial wall is and the internal thread being connected pawl external screw thread and matching, and outer wall is that insulating barrier is detained in the activity crimping being provided with anti-slip veins, the interior radial outside end face of described activity crimping button reduces, gradually for tightening up connection pawl fast.
A kind of prioritization scheme is, the end face outside of described activity crimping button is provided with the bottom surface of band centre bore, the outer surface tape insulation layer of this bottom surface.
A kind of embodiment is that described compliant conductive connector is the metal knitted line of multiply of outer insulating layer coating.
The present invention uses flexible connection body to eliminate the bending stress of hard wire to greatest extent, because compact, softness are easy to bending and are convenient to very much use in the terminal box in switch panel, and connection is reliable, replacing is easy, conveniently can realize hot line job, the link of adaptive terminal connecting hole and original power line exactly, avoid the damage that the stress pair of wire connection terminals screw of hard wire and terminal box cause, and the resistance of connector itself is little, can big current be adapted to, thus have wide range of applications.The tandem product of multi-size can be formed, have good market application foreground.
