Definitions

• the invention relates to a conductor connection terminal with a spring-loaded terminal connection, which has a clamping spring and a busbar, an electrical conductor being clampable by means of a clamping leg of the clamping spring on a conductor connection side of the busbar under spring force, and with a support element with a support section for contact on one of the conductor connection sides facing away side of the power rail.
• Conductor connection terminals with a spring-loaded terminal connection which has a clamping spring for clamping an electrical conductor to a busbar, belong to the prior art.
• Conductor connection terminals are constantly being further developed to reduce the size and production costs.
• technical solutions have been presented in the past in which a support element rests on the busbar or the busbar rests on a support element in order to mechanically stabilize the busbar.
• the object of the invention is to further optimize a conductor connection terminal in terms of its functionality and size and to provide a compact, versatile conductor connection terminal.
• the support element has a spring tongue with which an electrical contact element can be clamped to the busbar under spring force.
• the bearing element can be arranged with a bearing section adjacent to the conductor rail.
• the support element can contact the busbar at least in sections over a large area. It is conceivable that the busbar is supported on the support section of the support element in order to be able to better absorb the spring forces of the clamping spring acting on the busbar.
• the spring tongue can, for example, protrude from the support element.
• the spring tongue can connect to the support section and protrude from the support section.
• the spring tongue can form a further clamping point with the busbar in addition to a clamping point formed between the clamping spring and the busbar, at which an electrical contact element can be clamped by means of the spring tongue of the support element on the busbar under spring force.
• the conductor connection side of the busbar can be the side of the busbar, which is designed like a beam, for example, which faces the clamping spring and towards which the clamping leg of the clamping spring points.
• the side of the busbar facing away from the conductor connection side can be the rear side of the busbar opposite the conductor connection side (hereinafter also referred to as underside) of the busbar, on which there is no clamping leg of the clamping spring.
• the support element can thus adjoin the busbar on a side of the busbar facing away from the clamping spring.
• a spring tongue is understood as meaning an elastically movable, strap-shaped spring element which, for example, has one or more bends or angles and can exert a spring force in the direction of the busbar on a contact element that is inserted into the conductor terminal and contacted by the spring tongue.
• the spring tongue can, for example, at one end be connected to the bearing element and have a free end with an end region.
• An electrical contact element can be, for example, a contact pin, a stripped conductor wire or the tongue of a jumper.
• the spring tongue can have a spring bow from which a clamping arm for clamping the electrical contact element projects.
• the spring arc can, for example, be a bend or bend in the spring tongue with an angle or radius, so that the spring tongue changes the direction of its main extent as it progresses, for example starting from the support element in the direction of a free end of the spring tongue.
• a section of the spring tongue between the spring arc and the free end of the spring tongue can form the clamping arm of the spring tongue, the clamping arm exerting a spring force on the contact element to be clamped or clamped on the busbar.
• the spring tongue can be deflected by means of the spring bow in such a way that the clamping arm of the spring tongue is aligned pointing towards the busbar.
• the clamping force of the spring tongue exerted on a contact element to be clamped or to be clamped can be increased and the available installation space can be better utilized since the bending reduces the space requirement of the spring tongue.
• the spring tongue can be bent in an S-shape, at least in sections.
• the spring arc discussed above can describe part of the S-curve.
• a further angling or bending of the spring tongue can directly follow a connection area of the spring tongue with the bearing element, so that the spring tongue protrudes from the bearing element at an angle or radius.
• spring tongue and the spring tongue can, for example, have an alternating convex and have a concave course.
• the use of space in the conductor connection terminal in the area of the spring tongue can be optimized by the at least partially S-shaped bend and optionally by further bends or angles.
• the electrical contact element can be clamped to the busbar on a contact connection side.
• the contact connection side can be arranged, for example, on the side of the busbar that is remote from the conductor connection side. In this way, the conductor rail is used from two different, opposite sides, with the available installation space being optimally utilized.
• the contact connection side is arranged on another side of the busbar, for example on the conductor connection side or on another side such as an end face of the busbar.
• the spring tongue only has to be configured accordingly, so that it can form an additional clamping point for the contact element on the desired side of the busbar in addition to the conductor connection clamping point.
• An assignment of a respective surface of the busbar to a side is not necessarily associated with specific “sides” of the busbar. It is conceivable that a specific surface of the busbar runs partly on one side, for example the conductor connection side of the busbar, and partly on another side, for example the side of the busbar facing away from the conductor connection side. For this purpose, the busbar can be bent or angled, for example, so that a surface of the busbar is deflected from one side of the busbar to another side. It is thus conceivable that an electrical conductor clamped by the clamping spring and an electrical contact element clamped with the spring tongue can be clamped on different sides, but on the same clamping surface of the busbar. The side of the busbar on which an electrical contact element can be clamped or is clamped is referred to as the contact connection side.
• the spring tongue can essentially extend, starting from the support element, counter to the insertion direction of the electrical contact element to be clamped to the busbar. It is conceivable that the spring tongue extends essentially parallel to an inserted and clamped electrical conductor. Starting from the support element, the spring tongue can initially extend in sections transversely to an insertion direction of the electrical contact element and then, via a spring arc, transition into the extension directed in the opposite direction to a contact element to be inserted. It is also possible for the spring tongue to extend, at least in sections, essentially parallel to the busbar or inclined towards the busbar.
• the plane of insertion of an electrical conductor that can be clamped to the busbar can essentially run parallel to the plane of insertion of a contact element that can be clamped to the busbar.
• the contact element and the electrical conductor can thus be inserted into the conductor terminal in essentially parallel planes.
• a conductor and a contact element can be connected to the conductor connection terminal in a simple and convenient manner, and the available installation space is used efficiently.
• the directions of insertion of a conductor to be inserted and of a contact element to be inserted can be oriented in the same direction.
• the spring tongue can be formed in one piece with the support element, so that an integral configuration of spring tongue and support element is provided with one another.
• the spring tongue can be connected to the support element via a positive, non-positive or material connection or a separate connection means.
• the support element can have a solid base body or, for example, a side section bent from the support section of the support element, which stabilizes the support element in a material-saving manner.
• the support element can be a sheet metal machined in a stamping and bending process with one or more stamped, bent spring tongues.
• the sheet metal forming the support element that is processed in a stamping and bending process can have one or more stamped and bent side sections.
• the one-piece design of the spring tongue with the support element is a simple manufacture and assembly Conductor terminal with high stability and service life of the components of the conductor terminal allows.
• the spring tongue can have a bearing section for bearing the spring tongue on a side section of the support element.
• the spring tongue can have a bearing section for bearing the spring tongue on a base body of the support element. Because the spring tongue rests on the support element, improved stability of the conductor connection terminal and a higher spring force of the spring tongue can be achieved.
• the contact section of the spring tongue can be part of a spring bow of the spring tongue or can merge into the spring bow. It is also conceivable that the contact section of the spring tongue is a section of the spring tongue between a connection point with the support element and a spring bow of the spring tongue.
• the spring tongue can rest with the contact section, for example, on an edge of the side section or on a side surface of the base body of the support element.
• the contact section does not have to be in continuous contact with the side section or the base body, depending on the condition of the conductor connection terminal. A permanent investment is therefore not mandatory.
• the spring tongue can also only come into contact with the base body of the support element when an electrical contact element is inserted. In its contact section, the spring tongue can be supported against the side section or base body of the support element, so that the absorption of forces is improved. In addition, a favorable angling of the spring tongue towards the conductor rail with a resulting greater spring force can be achieved, for example, by means of a spring arc adjoining the contact section.
• the areas of the bearing element can be arranged one after the other in the following sequence, viewed from the inside outwards: Starting from a bearing section of the bearing element, a spring tongue protrudes at a connection point from the latter.
• the connection point is adjoined (possibly via a transition section) to a contact section with which the spring tongue can be attached to a section below the support section arranged side portion of the support element can create or rests on this.
• the contact section of the spring tongue can merge into a spring bow, from which a clamping arm protrudes towards the busbar.
• the clamping arm can, for example, at a clamping point with the busbar, transition into a bent tongue end to facilitate insertion.
• the contact section can form a stop to limit the insertion depth of the electrical contact element.
• the contact element can then, for example, hit the contact section with a contact element tip when it is inserted and cannot be inserted any further in the direction of the side section or base body of the support element.
• the spring tongue can form a receiving space or a receiving pocket for the electrical contact element. The stop or the receiving space ensures a controlled and safe insertion process for the electrical contact element.
• the conductor rail can be bent over in one end section in the direction of the spring tongue.
• the busbar may be bent with a bend between 90° and 270°, or between 120° and 240°, or between 150° and 210°.
• the busbar thus has a busbar bend in an end section.
• the busbar bend can form a clamping point for the electrical contact element with the spring tongue.
• the clamping point of the spring tongue for the electrical contact element can be formed on the same clamping surface of the busbar as the clamping point of the clamping spring for the electrical conductor.
• the busbar bend provides a structurally simple and material-saving solution for arranging the spring tongue and the busbar close together, so that the spring force of the spring tongue at the clamping point is greater than in the case of a busbar that has not been bent over.
