Description
Technical Field
[0001] The present invention relates to an electronic module, particularly a terminal block, capable of being arranged in series, the electronic module having a housing, at least one circuit board and at least two interfaces for electrical conductors, the electronic module further having a separating element disposed in the housing, the separating element being capable of linear movement parallel to the circuit board, the at least one circuit board having at least one first and at least one second contact surface capable of conducting electricity, and the separating element having at least one conductive segment that contacts the contact surface in a first position and thus connects the contact surface to each other in a conductive manner, such that current can be conducted between the interfaces by means of the at least one circuit board, i.e., from one interface to the other interface via the contact surface and the separating element, and the separating element being capable of moving to a second position in which current cannot be conducted between the interfaces. Background Technology
[0002] DE102015121057A1 discloses a terminal block having a housing and a separating element disposed within the housing for separating electrical conductors. The separating element is pull-out from the housing and includes a conductive section that conductively connects two contact elements sequentially disposed on a circuit board along the pull-out direction of the separating element, allowing current to be conducted between the contact elements. Pulling the separating element out of the housing disengages the connection between the contact elements, preventing current from being conducted between them.
[0003] The following problems exist in the terminal blocks according to the prior art: the repeated separation and restoration of the connection between the contact elements allows only very small manufacturing tolerances, which makes production expensive and costly and just happens to lead to high wear on the contacts when the separation element is repeatedly pulled out. Summary of the Invention
[0004] Based on the prior art, the object of the present invention is to provide an improved electronic module having electrical wires that can be separated in a particularly easy manner.
[0005] The present invention solves this problem by using an electronic module having the features of claim 1 that can be arranged in series.
[0006] According to the present invention, an electronic module, particularly a terminal block, capable of being arranged in series includes a housing, at least one circuit board, and at least two interfaces for electrical conductors. The electronic module further includes a separation element disposed within the housing, the separation element being linearly movable parallel to the circuit board. The at least one circuit board has at least one first contact surface and at least one second contact surface capable of conducting electricity, and the separation element has at least one conductive segment that, in a first position, contacts the contact surface and thus connects the contact surfaces to each other in a conductive manner, such that current can be conducted between the interfaces by means of the at least one circuit board, i.e., from one interface via the contact surface and the separation element to the other interface, respectively. The separation element can move to a second position in which current cannot be conducted between the interfaces. The at least one first contact surface and the at least one second contact surface are respectively disposed on opposite sides of the at least one circuit board. This enables particularly simple and reliable separation of the interfaces by means of the separation element.
[0007] In particular, the contact surfaces are arranged sequentially, perpendicular to the direction of movement of the separating element and the extension plane of the circuit board. Optionally, the contact surfaces may overlap each other, that is, have the same substantially two-dimensional shape in planes that are parallel to each other, and can be interconnected particularly easily by means of conductive segments.
[0008] In a particularly preferred variant, the separating element is movable within the housing and, in particular, cannot extend from the housing, resulting in a particularly space-saving implementation of the electronic module.
[0009] Preferably, the at least one first contact surface, the at least one second contact surface, and the extended plane of the circuit board are parallel to each other so that movement of the separating element can be achieved particularly easily.
[0010] The housing may have a guide portion that at least partially surrounds the separating element perpendicular to its direction of movement. Specifically, the guide portion may be an opening in the housing substantially corresponding to the size of the separating element, allowing the separating element to be inserted substantially seamlessly into the opening and / or the housing perpendicular to its direction of movement. The guide portion also enables precise repeatability of the movement of the separating element.
[0011] To facilitate particularly simple manipulation of the separating element, a pivotable lever is preferably provided on the housing, by means of which the separating element can be moved between a first position and a second position. Specifically, when the separating element is in the first position, the lever is in a pressed-in state, in which the upper surface of the lever is positioned substantially perpendicular to the axis corresponding to the direction of movement of the separating element. Preferably, when the separating element is in the second position, the lever is in a rotated-out state, i.e., a disengaged state, and in this state, the upper surface of the lever is positioned at an angle of 135° to 145°, more preferably about 140°, to the axis corresponding to the direction of movement of the separating element. Particularly preferably, the lever can be pivotable within an arc corresponding to the angular range between the pressed-in and disengaged states of the lever, and this arc is preferably 25° to 75°, particularly 45° to 55°.
[0012] In a preferred variant, the separating element is movable only within the housing, and a lever pivotally supported on the housing prevents the separating element from being pulled out of the housing, which further improves the reliability of the device.
[0013] Preferably, a pin guide is constructed on the separating element, in which a pin disposed on the lever is guided, allowing the separating element to move by means of the pin when the lever pivots. Preferably, when the lever pivots from the pressed-in position to the released position, the pin presses against a side of the pin guide facing the second position of the separating element and moves the separating element into the second position; conversely, when the lever pivots to the pressed-in position, the pin presses against a side of the pin guide facing the first position to move the separating element into the first position. Here, the pin guide may optionally be constructed such that the pin moves linearly within the pin guide when the lever pivots.
[0014] Optionally, the separating element has a profile that abuts against the protrusion of the lever without gap in the second position. This prevents the separating element from rotating in the second position and / or restricts the opening angle of the lever. To better secure the separating element in the second position, it can be supported at this location in this position on the protrusion of the lever by means of the profile and on the pin of the lever by means of the pin guide, these supports being offset along an axis perpendicular to the direction of movement to prevent the separating element from moving in one direction respectively. The profile is specifically used to facilitate the movement of the protrusion such that the opening angle of the lever can be determined by means of the profile, because the profile determines at which part of the lever's protrusion collides with the separating element during the pivoting movement of the lever.
[0015] In one embodiment, the at least one conductive section of the separating element may include at least one clamping contact surrounding the at least one circuit board and made of a conductive material, particularly a metal. Particularly preferably, the clamping contact or the entire conductive section is a contact spring.
[0016] In the context of this invention, "conductive" specifically means that the conductive section or the conductive portion of the electronic module (particularly the circuit board), or its material, has a conductivity greater than 1 MS / m. For this purpose, copper or aluminum is used, and more preferably, copper alloys, tin plating, silver, or gold are used to avoid oxidation or corrosion. In a variation, a nickel interlayer can also be used, which forms a diffusion barrier layer between the copper substrate and the tin plating. In other cases, the separating element, i.e., other than the conductive section, is preferably made of a plastic with a conductivity less than 1 S / m, such as polyamide or polybutylene terephthalate, similar to other non-conductive portions of the electronic modules that can be arranged in series, i.e., the terminals. The at least one circuit board may also include, for example, a composite material, such as FR4.
[0017] Specifically, the clamping contacts each contact the side of the circuit board having the contact surface with at least two contact fingers. In an alternative embodiment, the clamping contacts contact the side of the circuit board having the contact surface with a different number of contact fingers. Thus, the separating element can be used, for example, as a signal distributor, or can be used in parallel to supply current to multiple circuits. In a particularly advantageous variant, the number of the clamping contacts and / or the contact fingers, or their corresponding dimensions, can be adapted to the current intensity to be transmitted.
[0018] Preferably, the at least one clamping contact in the second position contacts the contact surface of the circuit board, so that current can be conducted between the interfaces via the at least one clamping contact.
[0019] In another embodiment, the separating element may include at least two conductive sections, specifically at least two clamping contacts, surrounding a circuit board of the electronic module.
[0020] Optionally, the electronic modules that can be arranged in series, or the terminals, may also have more than one of the separation elements, so that a particularly large number of interfaces can be electrically connected to each other and / or separated from each other in a space-saving manner. Attached Figure Description
[0021] The invention will now be explained in detail with reference to the accompanying drawings. In the drawings: Figures 1a to 1c A view of an electronic module implemented according to the invention as a terminal block is shown, wherein the disconnecting element is in a first position.
[0022] Figure 2a and Figure 2b Show Figure 1a A cross-sectional view of the terminal block, wherein the disconnecting element is in the second position.
[0023] Figure 3 Show Figure 1a and Figure 2a A perspective view of the terminal block in the second position.
[0024] Figure 4 Show Figures 1a to 3 A perspective view of the separated elements in the diagram. Detailed Implementation
[0025] exist Figure 1a The diagram shows a terminal block 1 with a housing 11, which is open on one side in the view. Two circuit boards 12 are housed within the housing, and the terminal block 1 has at least two interfaces 13, 14, 16, and 17 for electrical conductors. The electronic module also has a separation element 15 disposed within the housing 11, which is capable of linear movement parallel to the circuit boards 12 along the direction of movement B. Figure 1a The portion containing the separating element 15 in Figure 1b The diagram is enlarged in size. The direction of motion B extends parallel to the z-axis of the coordinate system shown and corresponds to the direction of the longitudinal extension dimension of the separating element 15. The circuit boards 12 each have a first conductive contact surface on a first side not visible here. On the visible second side 12b of the circuit boards 12, these circuit boards each have a second conductive contact surface 122. Therefore, the sides 12a and 12b and thus the contact surfaces 121 and 122 are positioned opposite each other along the y-axis direction of the coordinate system on mutually opposing sides of the circuit boards 12.
[0026] The separating element 15 here has two conductive sections 151 respectively disposed on the circuit board 12. Figure 1a and Figure 1b Only the section 151 disposed on the circuit board 12 below is visible. Here, the conductive section 151 is the clamping contact 1511, which contacts the contact surface in the first position P1 and thus connects the contact surfaces to each other in a conductive manner, so that by means of one of the circuit boards 12, interfaces 13 and 14 and 16 and 17 in FIG. 1 can be accessed respectively. Figure 1a Current is conducted between them.
[0027] Figure 1a Or rather Figure 1b The separating element 15 is optionally partially disposed in the guide portion 111 in the housing 11, which at least partially surrounds or encloses the separating element 15 perpendicular to its direction of movement B.
[0028] On housing 11, a pivotable lever 18 is supported on axis A, by means of which the separating element 15 can be moved from the first position P1 shown. Lever 18 is specifically pivotable about axis A by 25° to 75°, preferably 45° to 55°. To move the separating element 15, the lever has a pin, not visible here, disposed in a pin guide 152 in the separating element 15, and this pin also pivots and moves relative to the separating element 15 when lever 18 pivots, particularly linearly within the pin guide 152 (here along the x-axis), and the pin here (here in the positive z-axis direction) presses against the upper edge of the pin guide 152 and thereby causes the separating element 15 to move linearly in the direction of the second position (in the positive z-axis direction). Lever 3 has a gripping section 183 for easy operation.
[0029] Figure 1c Showing perpendicular to Figure 1a Top view of terminal 1 in the middle and Figure 1b The diagram is a cross-sectional view, that is, a cross-sectional view along the plane defined by the y-axis and z-axis. Here, the pin 181 of lever 18 is shown in the pin guide 152 for moving the separating element 15. It can also be seen that the two circuit boards 12 each have a first contact surface on the first side 12a visible here, and respectively have on the opposite second side 12b... Figure 1b The second contact surface 122. In the first position P1 of the separating element 15, the contact surfaces are interconnected via conductive sections 151, i.e., clamping contacts 1511, which are designed here as contact springs. As shown in the figure, the conductive sections 151 surround the circuit board 12. By means of the separating element 15, in its first position P1, it is therefore possible to separate from the second contact surface 122. Figure 1aOne of the interfaces 13 and 16 conducts current to the corresponding other interface 14 and 17 via the first contact surface and the second contact surface 122.
[0030] As from Figure 1b As can be seen, the contact surfaces (corresponding to sides 12a and 12b) are arranged sequentially, perpendicular to the direction of movement B of the separating element 15 and the extending plane of the circuit board 12. The at least one first contact surface 121, the at least one second contact surface 122, and the extending plane of the circuit board 12 extend parallel to each other and also parallel to the direction of movement B of the separating element 15 and the plane defined by the x-axis and z-axis of the coordinate system.
[0031] Separating element 15 can Figure 1a and Figure 1b The disconnecting element moves from terminal 1 to the second position P2. Figure 2a This is shown in the second position. In the second position P2, the conductive section 151 does not contact the contact surfaces 121, 122 and therefore cannot conduct current between the contact surfaces and the interface.
[0032] Figure 2b Show Figure 2a The diagram in the image is basically the same as Figure 1b The cross-sectional view corresponds to the cross-sectional view, where the components are separated as shown in the cross-sectional view. Figure 2a As shown in the second position P2, the first and second contact surfaces 121 and 122 are not electrically connected to each other here. Figure 2a and Figure 2b In the diagram, lever 18 is shown pivoted (optionally about 50°) about axis A, such that lever 18 is in... Figure 2b The visible sales number 181 is from the sales guidance department 152. Figure 2a The first end on the right side (on which the pin is located) Figure 1a (In the first position P1) it moves along the x-axis to the pin guide 152. Figure 2a The left end moves along the z-axis in the direction of movement B of the separating element 15. The lever 18 can also pivot in the opposite position, so that the device, or separating element 15, can pivot from the second position P2 back to the first position P1.
[0033] Figure 3 Show Figure 2a The separating element 15 and the upper circuit board 12, facing each other in the y-axis direction, are shown in a top view, roughly as the first side 12a and the first contact surface 121 of the circuit board 12. The clamping contacts 1511 shown continue around the circuit board 12 in the second position P2, but these clamping contacts, with their three contact fingers 1512, only contact non-conductive sections of the circuit board 12. Figure 3 In the figure, the pin 181 of the lever 18 is also visible within the pin guide 152. The separating element also has a profile 154 against which the protrusion 182 of the lever 18 abuts.
[0034] Figure 4 The isometric view of the separating element 15 in the aforementioned figures is shown in the top view of the two clamping contacts 1511, wherein the clamping contacts are... Figures 1a to 3 The circuit board 12 is connected to the center. The clamping contacts 1511 are contact springs with six contact fingers 1512. In the aforementioned figures, three of the contact fingers contact one of the sides 12a and 12b of the circuit board.
