Description
Technical field
The present invention relates to a kind of framework clamping element, be used in particular for having the electromechanical switching device of integrated contact element, its middle frame clamping element has the framework that has the screw thread that is used for attachment screw.
Background technology
This clamping device should be installed on the housing of electromechanical switching device, and clamping device forms between the inside of electronic installation and ancillary equipment and is electrically connected.Can connect the special lead that is used to the equipment energize by this way.
Existing two kinds clamp fundamental type.A kind of fundamental type is a screws clamp, and wherein, a needs wire connecting is introduced and is fixed in the fastening point with a hand, and tightens pinching screw with the another hand.Another kind of clamping fundamental type is the stage clip terminal; Wherein, With a hand instrument, for example screwdriver are inserted in the release opening; Purpose is will need wire connecting to introduce and be fixed in the fastening point that is unlocked like this with the another hand, from the release opening, instrument is being removed its elasticity clamping effect of back performance up to fastening point.In two kinds of clamping fundamental types, also just require corresponding work step " assembling " and " fixing " each other all the time.
The switching device that has the megohmite insulant shell that in family installs with industry, uses is equipped with output-and current feed terminal usually, and this terminal is arranged in the terminal accommodation section of for this reason designing on the both sides of housing.Output-be electrically connected with the track that is connected of attaching troops to a unit of switching device with current feed terminal.Electrical connection between external circuit that needs protection and lead-out terminal, and the connection between transmission network and current feed terminal realizes that through pinching screw pinching screw is arranged in the top of described terminal.This screw has the end assembly usually, and the effect of end assembly is, when tightening with respect to the conductor of related circuit, imports, thereby makes the clamping that between screw and affiliated brace, is fixed of this conductor.
The requirement that exists is that the conductor that has little cross section all will be guaranteed in the shaped as frame terminal of electromechanical switching device, to clamp with the conductor that has big cross section.At this, be that the shaped as frame terminal is not closed in straight contact element fully, and conductor is drawn out under the situation of the check that clamps in the problem that exists aspect the little conductor.Otherwise the problem that in having the conductor of big cross section, exists is, this conductor is pulled out at terminal under the situation of very high load of check and is drawn out.
Summary of the invention
Correspondingly, the objective of the invention is, realize a kind of framework clamping element that is used for electromechanical switching device, it had both guaranteed to clamp the conductor that has little cross section, guaranteed to clamp the conductor that has big cross section again.
This purpose realizes through a kind of framework clamping element with the said characteristic of claim 1.The content that favourable structure can be independent or that combination with one another is used and improvement project are dependent claims.
According to the present invention, this purpose realizes that through a kind of framework clamping element it is used in particular for having the electromechanical switching device of integrated contact element, and its middle frame clamping element has the framework that has the screw thread that is used for attachment screw.The invention is characterized in that contact element has embossing on upper side.To design to conductor especially according to contact element of the present invention, and promptly be provided preferably with embossing, thereby make terminal mesh, so that terminal is closed fully as counterpart in both sides with little cross section.Can make the conductor that has little cross section clamped by this way.Contact element according to the present invention designs for the conductor with big cross section like this, promptly preferably install be transverse to smooth contact element with so that also be transverse to the groove line of electric conductor, the groove line can be implemented in and keep high tightening force when clamping check.
Framework clamping element according to the present invention has a framework that has two minor faces and two long limits.On a minor face, be furnished with the screw thread that has screw.Between the long limit of the preferred parallel design of framework, be furnished with contact element.This contact element preferably has two lateral side regions and a zone line.Lateral side regions preferably is designed to smooth face, and zone line has smooth spigot surface at the center, and it is respectively in changing two surfaces that reduce that are designed to embossing on a side on the long limit of framework.The surface that reduces is preferably designed for scarf and therefore is designed to roof-shaped.
This contact element has the upper surface that has geometrical shapes, and this geometrical shapes is used for the clamping effect of nipped electric conductor is optimized.It is the groove line of form that this geometrical shapes preferably is designed to the extension of the beam shape that is arranged in parallel.This groove line for example may be transverse to the conductor that is introduced in the framework clamping element.Preferably, contact element also is furnished with geometrical shapes at lower surface, and this geometrical shapes realizes the clamping effect below contact element of the electric conductor that is introduced into is optimized.
According to contact element of the present invention especially also design like this, promptly be provided with embossing, thereby make terminal can be used as the counterpart engagement, so that terminal is closed fully in both sides.Utilize this mode can clamp little conductor in an advantageous manner.In addition, contact element according to the present invention is furnished with the groove line, and it is transverse to smooth contact element setting, and the effect of groove line is to remain on tightening force high when clamping check.
Correspondingly be furnished with embossing on the one hand according to contact element of the present invention, this embossing is necessary for closing terminal fully, and is furnished with the groove line on the other hand, and the groove line has realized utilizing the less relatively tightening torque of terminal to maintain big conductor.
Utilization framework clamping element according to the present invention is clamped in conductor on the electromechanical assembly, particularly is clamped on circuit breaker, protection relay and/or the overload relay.The framework clamping element has not only realized clamping little conductor but also realized clamping big conductor at this.Contact element is designed to for this reason, and it not only has the embossing in both sides, but also has the groove line, and this groove line is transverse to smooth contact element setting, so that remain on the high tightening force that occurs when clamping check.
