Abstract
An electrical connector includes a plug which is designed as a threaded sleeve for screwing on a union nut or for screwing into a stationary housing component of an electronic device. The external thread of the threaded sleeve has at least one threadless area provided in the plug-in direction into which a matching internal thread of a union nut or of a housing can be plugged in almost completely, in such a way that tightening of the threaded joint is reduced to one half or maximum a full revolution. The construction allows for the use of complete screw threads and thus the combination with standard connectors of the same commercially available size and type of connection.
Claims17
An electrical connector comprising:
- a plug including a threaded sleeve, the threaded sleeve including an external thread having at least one threadless area;
- and
- a socket connectable to the plug and including a union nut, the union nut including an internal thread configured for threaded engagement with the external thread of the plug;
- wherein the internal thread of the union nut is configured to be received by the at least one threadless area and tightened onto the external thread;
- the at least one threadless area includes a plurality of threadless areas;
- and the internal thread includes a plurality of threaded areas matching the threadless areas.
An electrical connector comprising:
- a plug including a threaded sleeve, the threaded sleeve including an external thread having at least one threadless area;
- and
- a socket connectable to the plug and including a union nut, the union nut including an internal thread configured for threaded engagement with the external thread of the plug;
- wherein the internal thread of the union nut is configured to be received by the at least one threadless area and tightened onto the external thread;
- the external thread includes a respective individual first thread on each side of the at least one threadless area, the individual first threads being aligned with each other;
- the internal thread includes respective individual second threads;
- and the individual first and second threads each have a respective chamfer at a start of the respective thread so as to enable an easier insertion of a counterthread area when tightening the internal thread onto the external thread.
An electrical connector comprising:
- a plug including a threaded sleeve, the threaded sleeve including an external thread having at least one threadless area;
- and
- a socket connectable to the plug and including a union nut, the union nut including an internal thread configured for threaded engagement with the external thread of the plug;
- wherein the internal thread of the union nut is configured to be received by the at least one threadless area and tightened onto the external thread;
- the external thread includes a respective individual first thread on each side of the at least one threadless area, the individual first threads being aligned with each other;
- the internal thread includes respective individual second threads;
- and the individual first and second threads each include a respective sharp edge at an end of the respective thread so as to prevent turning past a tangential removal position when unscrewing the internal thread from the external thread.
An electrical connector comprising:
- a plug including a threaded sleeve, the threaded sleeve including an external thread not having a threadless area;
- and
- a socket connectable to the plug and including a union nut, the union nut including an internal thread configured for threaded engagement with the external thread of the plug, the internal thread having at least one threadless area.
An electrical connector comprising:
- a plug including a threaded sleeve, the threaded sleeve including an external thread having a plurality of threadless areas;
- and
- a socket disposed in a stationary housing component and connectable to the plug, the socket including an internal thread configured for threaded engagement with the external thread of the plug;
- wherein the internal thread of the socket includes a plurality of threaded areas matching and configured to receive the threadless areas for tightening the external thread onto the internal thread.
An electrical connector comprising:
- a plug including a threaded sleeve, the threaded sleeve including an external thread having at least one threadless area;
- and
- a socket connectable to the plug and including a union nut, the union nut including an internal thread configured for threaded engagement with the external thread of the plug;
- wherein the internal thread of the union nut includes at least one threaded area matching the at least one threadless area and configured to be received by the at least one threadless area and tightened onto the external thread.
