[0001] The utility model relates to a lever clamp and also relates to a connecting assembly having the lever clamp. Background Art

[0002] Lever clamps are used, for example, to fix electrical conductors in connection terminals and to press them against current bars or contacts. This is usually a releasable fixation, wherein the respective electrical conductor assigned to the lever clamp can be introduced into and removed from the connection terminal as long as the lever clamp is in its open position, and wherein the relevant electrical conductor can be fixed in the connection terminal by pivoting the lever clamp from the open position into its clamping position or closed position.

[0003] In the field of electrical connection technology, there is a constant demand to provide cost-effective, reliable and easily producible components for contacting and / or fastening electrical conductors. Utility Model Content

[0004] Against this background, the technical object of the present invention is to provide a lever clamp which can be manufactured simply and cost-effectively and which also enables a reliable fixation of the conductor. In addition, a connecting assembly having such a lever clamp should be proposed.

[0005] 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 and the following description.

[0006] According to the utility model, a lever clamp is proposed, comprising a lever section, wherein the lever section has an operating side for operating the lever clamp and a fixing side facing away from the operating side for fixing the lever clamp on a receiving structure, the lever clamp having a first locking tab, a second locking tab and a clamping tab, wherein the clamping tab is arranged to accommodate a conductor end of an electrical conductor, wherein the clamping tab is arranged between the first locking tab and the second locking tab, wherein the first locking tab, the second locking tab and the clamping tab extend in the area of ​​the fixing side, wherein the first locking tab has a first forming element for fixing the lever clamp on the receiving structure in a shape-fitting manner, wherein the second locking tab has a second forming element for fixing the lever clamp on the receiving structure in a shape-fitting manner, and wherein the clamping tab has a third forming element for fixing the lever clamp on the receiving structure in a shape-fitting manner.

[0007] The lever clamp can thus be fixed, in particular locked, in particular at three positions or points on the receiving structure in order to securely clamp the electrical conductor to the relevant receiving structure. The lever clamp can thus fix the electrical conductor to the receiving structure in particular without tools. Thus, a simple and cost-effective fixing of the relevant electrical conductor to the corresponding receiving structure can be achieved.

[0008] In particular, the lever clamp can be designed in one piece or in one piece.

[0009] In particular, it can be provided that the lever clamp has no movable parts, such as screws, buttons or the like, which are required to realize the clamping function of the lever clamp. Of course, the lever clamp itself can be moved and is flexible in order to realize the clamping function. If it is mentioned here that the lever clamp has no movable parts, this means that the lever clamp has no individual parts that are supported on one another or can be moved relative to one another.

[0010] The lever clamp can be made of plastic. In particular, it can be provided that the lever clamp does not have any metal material. Therefore, the lever clamp can be provided as a plastic component in a simple and cost-effective manner. For example, the lever clamp can be manufactured by an injection molding process.

[0011] The first profiled element of the first locking tab can have a supporting element and a locking element, wherein the locking element can have a greater distance to the lever section than the supporting element. For example, the locking element can be provided to hook onto the receiving structure from behind in the manner of a barb in order to fix the first locking tab to the receiving structure in a form-fitting manner. The supporting element can, for example, serve to support the lever clamp on the receiving structure and, for example, can serve as a stop in order to limit the travel of the first locking tab into a corresponding opening or receptacle of the receiving structure.

[0012] The second profiled element of the second locking tab can have a supporting element and a locking element, wherein the locking element can have a greater distance to the lever section than the supporting element. For example, the locking element can be provided to hook onto the receiving structure from behind in the manner of a barb in order to fix the second locking tab to the receiving structure in a form-fitting manner. The supporting element can, for example, be used to support the lever clamp on the receiving structure and, for example, can serve as a stop in order to limit the travel of the second locking tab into a corresponding opening or receptacle of the receiving structure.

[0013] The supporting element and / or the locking element can be designed at least in sections in a wedge-shaped manner. The wedge shape can in particular enable the relevant locking tab to be easily introduced into the relevant opening of the receiving structure.

[0014] It can be provided that the support element and / or the locking element can be cylindrically configured at least in sections, in particular cylindrically configured. The cylindrical shape can in particular enable a defined support or a defined abutment, in particular a linear contact, on a corresponding surface of the receiving structure, and / or enable a swing.

[0015] The first locking tab and / or the second locking tab can be configured in a fork-shaped manner and have a first locking arm and / or a second locking arm spaced apart from each other, wherein the first and / or the second profiled element can in particular be configured on the first locking arm and / or the second locking arm. In this way, the first and / or the second locking tab can be configured flexibly and deformably.

[0016] Observed from the lever section, the first locking tab and / or the second locking tab can extend in a freely protruding manner. In particular, the first locking tab and / or the second locking tab can be arranged to be inserted into a corresponding opening of the receiving structure.

[0017] With respect to the receiving structure, the terms "receiving portion" and "opening" are used synonymously herein.

[0018] The first profiled element of the first locking tab may extend in directions that diverge from each other on the sides of the locking tab that diverge from each other. For example, the first locking tab may have two support elements that extend away from each other on the sides of the locking tab that diverge from each other. For example, the first locking tab may have two locking elements that extend away from each other on the sides of the locking tab that diverge from each other.

[0019] In particular, it can be provided that if the first locking tab is forked, the first locking element is arranged on a first locking arm of the first locking tab and the second locking element is arranged on the other first locking arm of the first locking tab. It can also be provided that if the first locking tab is forked, the first supporting element is arranged on a first locking arm of the first locking tab and the second supporting element is arranged on the other first locking arm of the first locking tab.

[0020] The second profiled element of the second locking tab can extend in directions that diverge from each other on the sides of the locking tab that diverge from each other. For example, the second locking tab can have two support elements that extend away from each other on the sides of the locking tab that diverge from each other. For example, the second locking tab can have two locking elements that extend away from each other on the sides of the locking tab that diverge from each other.

[0021] In particular, it can be provided that if the second locking tab is forked, the first locking element is arranged on a second locking arm of the second locking tab and the second locking element is arranged on the other second locking arm of the second locking tab. It can also be provided that if the second locking tab is forked, the first supporting element is arranged on a second locking arm of the second locking tab and the second supporting element is arranged on the other second locking arm of the second locking tab.

[0022] The clamping web can have a central section with a through-hole for receiving a conductor end of an electrical conductor. The through-hole can have a circular cross section or be a cylindrical through-hole, for example.

[0023] The third shaped elements of the clamping tabs can be formed on the middle section, wherein these third shaped elements can be configured, for example, in a wedge shape. If wedge-shaped third shaped elements are provided, these third shaped elements are used to fix the clamping tabs to the receiving structure in a form-fitting manner similar to the locking tabs described above according to the type of barbs.

[0024] The clamping web can have third locking arms which are spaced apart from one another, on which a third shaped element of the clamping web, in particular a third bolt-shaped shaped element, can be arranged.

[0025] The above-described middle section of the clamping tab can be arranged between the third locking arms of the clamping tab. A gap can be formed between each respective third locking arm of the clamping tab and the middle section. In this way, the insertion of the clamping tab into the corresponding opening of the receiving structure can be simplified, because the gap formed between the middle section and the third locking arms gives the clamping tab flexibility.

[0026] The lever section and the clamping tab of the lever clamp can be connected to each other by a U-shaped transition section. The U-shaped transition section enables the actuating force applied to the lever section to be transmitted to the clamping tab so as to facilitate the conductor end to be fixed of the electrical conductor to be pressed onto the receiving structure.

[0027] It can be provided that the second locking arm of the second locking tab is fixed or formed on the U-shaped transition section. The second locking arm of the second locking tab can be fixed or formed in particular on the sides of the U-shaped transition section facing away from each other.

[0028] As already described above, the lever clamp can be formed in one piece and can be produced in particular by an injection molding method.

[0029] The lever section can have a notch adjacent to the first locking tab. The notch increases the flexibility of the lever section.

[0030] The lever section can taper from the second locking tab in the direction of the first locking tab. In other words, the lever section has a greater width in the region of the second locking tab than in the region of the first locking tab. In particular, the width of the lever section can taper in a wedge-shaped manner starting from the second locking tab in the direction of the first locking tab. This can also increase the flexibility of the lever section.

[0031] The clamping tab can be arranged adjacent to the second locking tab, wherein the clamping tab can have a smaller distance to the second locking tab than the first locking tab. In this way, when clamping the electrical conductor, the lever clamp is first pre-positioned with the second locking tab on the corresponding receiving structure, so that the actuating force is then applied to the lever section in the region of the first locking tab. Since the clamping tab is positioned closer to the second locking tab than the first locking tab in this case, the actuating force acting on the clamping tab is intensified due to the lever effect.

[0032] According to the utility model, a connecting assembly is also provided, which has a accommodating structure and a lever clamp according to the utility model, wherein the accommodating structure is a circuit board, wherein the circuit board has a first accommodating portion for accommodating a first locking tab, wherein the circuit board has a second accommodating portion for accommodating a second locking tab, wherein the circuit board has a third accommodating portion for accommodating a clamping tab, and wherein the contacts of the circuit board are arranged in the area of ​​the third accommodating portion.

[0033] The receptacle of the receptacle structure can also be referred to as an opening.

[0034] In particular, the opening may be a through-hole of a circuit board.

[0035] Thus, the conductor end of the electrical conductor to be in contact with the contact of the circuit board can be fixed on the circuit board, wherein the lever clamp with its locking tab is inserted into a corresponding receptacle of the circuit board and fixed to the circuit board in this way, wherein the clamping tab applies a clamping force to the conductor end of the electrical conductor resting on the clamping tab in the state of complete assembly on the circuit board, and the conductor end is thus permanently pressed against the contact of the circuit board.

[0036] In the state of being completely mounted on the circuit board, the lever clamp can in particular exert a spring-elastic clamping force on the conductor end of the electrical conductor in order to provide a permanent and reliable contact between the conductor end and the contact of the circuit board.

[0037] In particular, the clamping force can be provided without an additional spring element and can be brought about, in particular, solely by the material and shape of the lever clamp or by an elastic deformation of the lever clamp in the fully assembled state.

[0038] In particular, the lever clamp can be designed in one piece and can be provided not only for fastening the lever clamp itself to the printed circuit board, but also for fastening the conductor to be connected to the contact of the printed circuit board. BRIEF DESCRIPTION OF THE DRAWINGS
