Description

Connecting device, connecting element and electronic equipment Technical Field The present invention relates to a connection device for connecting electrical conductors. The invention further relates to a connecting element having such a connecting device and to an electronic device. Background The connection device for connecting electrical conductors generally has a current bar and a clamping spring for clamping the conductor to be connected to the current bar. The clamping spring is usually designed as a helical torsion spring having a holding leg which is mounted in a fixed manner and a clamping leg which is arranged in a pivotable manner relative to the holding leg. The clamping leg can be transferred by a pivoting movement into an open position in which a conductor can be inserted into and led out of a conductor connection chamber between the clamping leg of the clamping spring and the current bar, and into a clamping position in which the conductor inserted into the conductor connection chamber is clamped against the current bar. Disclosure of Invention The object of the invention is to provide a connecting device, a connecting element and an electronic device, which are characterized in that the conductors are reliably connected while having a structure that is as compact as possible. According to the invention, this object is achieved by the features of the independent claims. Advantageous embodiments and advantageous developments of the invention are given in the dependent claims. The connecting device according to the invention has a current bar and a clamping spring for clamping a conductor to be connected to the current bar, wherein the clamping spring has a clamping leg and a holding leg which can be moved into an open position and into a clamping position, wherein the clamping leg clamps the conductor to be connected to the underside of the current bar, and wherein the holding leg has a first leg section which is of curved design and is supported on the underside of the current bar opposite the underside in the event of a line contact. According to the invention, the clamping spring is supported and braced with its holding legs at least in sections on the current bar. The clamping spring is supported at least by the first leg section of the holding leg on the upper side of the current bar, and the conductor to be connected is clamped by the clamping leg of the clamping spring on the lower side opposite to the upper side, so that a self-stabilizing system is formed, which enables a reliable and stable clamping of the conductor to be connected. The first leg section is configured in a curved manner, with which the retaining leg is placed or supported on the upper side of the current bar. The first leg section of the retaining leg is therefore not exactly of straight or flat design and is not placed over the upper side of the current bar. In contrast, by virtue of the curved shape, the first leg sections rest on the upper side of the current rail only with a partial surface of the first leg sections that is smaller than the total area of the first leg sections. The remaining part of the first leg section is preferably arranged at a distance from the current bar, in particular at a distance from the upper side of the current bar. At the point where the first leg section abuts the upper side of the current bar, a line contact is formed between the current bar and the first leg section, which means that the first leg section abuts the current bar linearly and thus along a preferably narrow line. The line contact preferably extends along the width of the current bar or along the width of the first leg section and thus transversely to the length of the current bar or transversely to the length of the first leg section. Thus, the line contact requires a very small area, so that the connection device can be constructed more compactly. Two such clamping springs can also be provided on the current bar, so that two conductors can be connected. Preferably, the first leg section is configured in an S-bend. The first leg section has sufficient stability by the S-shape. In the region of the curvature of the S-leg section pointing in the direction of the current strip, the first leg section preferably forms a line contact with the current strip. The first leg section has two bends which are formed at a distance from one another along the length of the first leg section by means of an S-shape, wherein one of the two bends rests on the current strip in order to form a line contact and the other of the two bends is spaced as far as possible from the current strip, in particular from the upper side of the current strip. The retaining leg is preferably divided into a plurality of leg sections, wherein the leg sections can each be oriented at an angle to one another. Preferably, the holding leg has, in addition to the first leg section, a second leg section and a third leg section, wherein the second leg section can
