[0003] b) a first spring force clamping connection for connecting a first electrical line;

[0004] c) a second spring force clamping connection for connecting a second electrical line;

[0007] f) wherein the second spring force clamping connection has a second clamping spring and a second counter bearing, between which a second clamping point is formed, at which the second electrical line can be fixedly clamped between the second clamping spring and the second counter bearing;

[0008] g) wherein the first clamping point and the second clamping point are arranged spaced apart from the outer wall of the housing inside the housing BACKGROUND

[0009] Such a terminal is known from DE 1 917 503 Al. SUMMARY

[0010] The invention is based on the object of specifying a further improved terminal, which can be well miniaturized, in particular for connecting small cross-section electrical lines.

[0011] The object is achieved in a terminal of the type mentioned at the outset in that the first counter bearing and / or the second counter bearing is formed from an insulating material, in particular from the material of the housing. Such a terminal can in particular be designed without a separate busbar or without a busbar at all. The current transfer between the first and the second spring force clamping connection is then effected via the first and the second clamping spring and the electrical connection thereof. In this way, the terminal can be constructed very simply and with a small number of components, in particular it can be constructed from only the housing, the first and the second clamping spring and the electrical connection between the clamping springs.

[0012] Advantageously, the first and / or the second mating bearing can be formed directly from the material of the housing, for example by an inner wall formed to this end inside the housing. The housing can be formed from an insulating material housing. This allows a particularly cost-effective production of the terminal and further simplifies the installation.

[0013] The terminal can be particularly well miniaturized due to its simple construction and the small number of components.

[0014] According to an advantageous design of the application, the first and the second clamping spring are formed as a one-piece metal piece. Thereby, the terminal is produced more cost-effectively and the installation is further simplified. The metal piece with the first and the second clamping spring can be supported and fixed therein, for example in a central region thereof, in particular in the region between the first and the second clamping leg, in the material of the housing.

[0015] According to an advantageous design of the application, the metal piece with the first and the second clamping spring is the only metal piece of the terminal. Thereby, the terminal is produced more cost-effectively and the installation is further simplified.

[0016] According to an advantageous design of the application, the metal piece with the first and the second clamping spring is formed from a copper alloy. Thereby, the transmission resistance for the current transmission is minimized and the current-carrying capacity of the metal piece is increased. Here, even if the first and the second clamping spring are not made from the conventional spring steel usually used for clamping springs, they can still have sufficient elastic properties.

[0017] According to an advantageous design of the application, the first clamping spring has a first bearing leg for fixing the first clamping spring in the housing, a first clamping leg for clamping fixation of the first electrical conductor at the first clamping point and a first spring bow arranged between the first clamping leg and the first bearing leg, and / or the second clamping spring has a second bearing leg for fixing the second clamping spring in the housing, a second clamping leg for clamping fixation of the second electrical conductor at the second clamping point and a second spring bow arranged between the second clamping leg and the second bearing leg. Thereby, a particularly good spring action can be achieved when the first and / or the second clamping spring is constructed small. The bearing legs allow a reliable fixation of the first and / or the second clamping spring in the housing, for example by corresponding housing walls, through which the first and / or the second bearing leg is guided.

[0018] The terminal according to the application is particularly suitable for use with relatively small conductors, for example with a conductor cross-section of 0.03 mm 2 to 0.2 mm 2The conductors are used together and / or for low currents, for example up to a maximum of 2 A. The terminal is suitable, for example, for model construction applications, toys, communication devices and computer network interfaces.

[0019] The first clamping leg is able to hold the first clamping spring in a slight pretension relative to the first mating support even when no electrical conductor is inserted. The same applies to the second clamping leg.

[0020] According to an advantageous design of the application, the first clamping leg has a window-like first passage opening which is configured for the passage of the first electrical conductor, and / or the second clamping leg has a window-like second passage opening which is configured for the passage of the second electrical conductor. In this way, the respective electrical conductor can be clamped particularly efficiently at the clamping site. The first and / or second clamping leg can have a clamping edge for securing the clamped electrical conductor. The window-like first and / or second passage opening can be circular, oval or polygonal, for example quadrangular, in particular rectangular. The window-like first and / or second passage opening can be surrounded on three or four sides by the material of the first clamping leg.

[0021] According to an advantageous design of the application, at the first clamping leg, in particular at the inner circumference of the first passage opening, a first clamping tab is provided which is configured for clamping the first electrical conductor to the first mating support, and / or at the second clamping leg, in particular at the inner circumference of the second passage opening, a second clamping tab is provided which is configured for clamping the second electrical conductor to the second mating support. In this way, the electrical conductors can be secured particularly reliably by means of the clamping achieved by the clamping spring. For example, the clamping edge mentioned above can be provided at the first or second clamping tab. The first clamping tab can here, in an advantageous design, be bent away from the first clamping leg in the conductor insertion direction of the first electrical conductor and / or towards the first support leg. It is also possible for the first clamping tab to be bent away opposite the conductor insertion direction of the first electrical conductor and / or away from the first support leg. It can be advantageous in this case for there to be a clearance and a mating support in the region of the first conductor introduction opening or the first conductor introduction channel. In a preferred embodiment, the second clamping tab can be bent away from the second clamping arm in the conductor insertion direction of the second electrical conductor and / or in the direction of the second support leg. It is also possible for the second clamping tab to be bent away opposite the conductor insertion direction of the second electrical conductor and / or away from the second support leg. It can be advantageous in this case for there to be a clearance and a mating support in the region of the second conductor introduction opening or the second conductor introduction channel.

[0022] The clamping tabs can be bent away from the clamping legs, for example, in a relatively small angular range, for example in a range of 5 to 45 degrees. The clamping tabs can also be bent away at a larger angle, for example up to 60 degrees or up to 90 degrees or more. By virtue of the geometry of the clamping tabs, a gentle installation angle which matches relatively thin electrical conductors can be achieved in particular when clamping, and the clamping spring is also kept in a defined pretension. An accidental severing of such conductors by the clamping legs is avoided in particular. The clamping tabs can constitute a pressing surface for pressing the electrical conductor against the respective mating support, i.e. in the case in question the clamping of the electrical conductor takes place not by the clamping edge but by the pressing surface of the clamping tab, in particular when the angle of bending away is large, for example more than 80 degrees or more than 90 degrees. The configuration with such a pressing surface has the advantage that the risk of the clamped electrical conductor being severed by the pressing, in particular in the case of relatively thin conductors, is minimized.

[0023] According to an advantageous design of the application, the first support leg is connected to the first spring bow via a first connecting section, wherein the first connecting section is inclined at an angle of between 10 and 80 degrees with respect to the first support leg, and / or the second support leg is connected to the second spring bow via a second connecting section, wherein the second connecting section is inclined at an angle of between 10 and 80 degrees with respect to the second support leg. This allows a reliable fixing of the first and / or second clamping spring in the housing in the direction of insertion of the respective electrical conductor, for example by means of corresponding housing walls, between which the first and / or second support leg is led through. The metal piece with the first and second clamping spring can then be configured, for example, in the shape of an omega.

[0024] According to an advantageous design of the application, the bending direction of the first spring bow is opposite to the bending direction between the first support leg and the first connecting section, and / or the bending direction of the second spring bow is opposite to the bending direction between the second support leg and the second connecting section. In this way, the first and second clamping spring can be particularly well and space-savingly integrated into a small-constructed housing. Furthermore, it becomes possible to simply and efficiently manually operate the first and / or second clamping spring, as is also set out below.

[0025] The manual operation of the first and / or second spring force clamping connection to open the respective clamping point by manual operation can be carried out, for example, by means of a separate operating tool, for example by pressing onto the respective clamping spring by means of a screwdriver.

[0026] According to an advantageous design of the application, it is proposed that the terminal has a first operating element for manually operating the first spring force clamping connection and / or a second operating element for manually operating the second spring force clamping connection. Since the terminal has such suitable operating elements for manual operation, a simple operation by the user is currently possible, in particular without additional tools.

[0027] According to an advantageous design of the application, it is proposed that the first operating element is designed as an operating press or an operating lever, in particular as an operating press or an operating lever which is formed in one piece with the material of the housing, and / or the second operating element is designed as an operating press or an operating lever, in particular as an operating press or an operating lever which is formed in one piece with the material of the housing. Such operating elements allow an ergonomic and intuitive handling of the terminal. Furthermore, these operating elements can be particularly advantageously integrated into a miniaturized housing, in particular in a design which is formed in one piece with the material of the housing.

[0028] According to an advantageous design of the application, it is proposed that the first operating element is designed to transmit a manual operating force to the first spring bow, and / or the second operating element is designed to transmit a manual operating force to the second spring bow. This is also required for the configuration of the terminal in miniaturized form. In particular, no additional elements, such as separate operating tabs, are required at the first and / or second clamping spring.

[0029] According to an advantageous design of the application, it is proposed that the terminal is designed as a pass-through terminal, wherein the housing has a first conductor introduction opening assigned to the first spring force clamping connection and a second conductor introduction opening assigned to the second spring force clamping connection, wherein the first and second conductor introduction openings are arranged on mutually oppositely facing housing sides of the housing. Such a pass-through terminal is suitable for a large number of electrical wiring tasks, in particular for use in a mounting box. The terminal can in particular be designed as a terminal block.

[0030] According to an advantageous design of the application, it is proposed that the first spring force clamping connection is designed as a tension spring connection, and / or the second spring force clamping connection is designed as a tension spring connection. This allows a high clamping force and, corresponding thereto, a reliable clamping of the respective electrical conductor in a small construction of the first and / or second clamping spring. The tension spring connection can for example be designed similar to a cage tension spring.

[0031] According to an advantageous design of the application, it is proposed that the first spring force clamping connection is configured to pull the first electrical line, by means of the first clamping spring, in a direction away from an outer wall of the housing closest to the first clamping point to the first mating support; and / or the second spring force clamping connection is configured to pull the second electrical line, by means of the second clamping spring, in a direction away from an outer wall of the housing closest to the second clamping point to the second mating support. By means of the first spring force clamping connection and / or the second spring force clamping connection, the connected electrical lines can be centered, for example approximately centrally, in the housing, when they are fixedly clamped, for example centrally in the direction of insertion of the electrical lines and / or transversely to the direction of insertion of the electrical lines. This also achieves good insulation safety in the case of miniaturized terminal blocks.

[0032] According to an advantageous design of the application, it is proposed that the first clamping spring is designed as a tension spring with a first support leg facing away from the first through-opening and / or the second clamping spring is designed as a second clamping spring with a second support leg facing away from the second through-opening.

[0033] According to an advantageous design of the application, a first electrical line accommodation space for accommodating a first electrical line and a second electrical line accommodation space for accommodating a second electrical line are formed in the housing, wherein the housing has at least one partition wall, by means of which the first electrical line accommodation space is separated from the second electrical line accommodation space. The partition wall can thus be formed by the material of the housing.

[0034] The first and / or the second electrical line accommodation space can have a stop for limiting the insertion depth of the electrical line. Advantageously, the stop can be formed by the partition wall.

[0035] According to an advantageous design of the application, the terminal block has, in the arrangement direction, a plurality of first spring force clamping connections arranged in the housing side by side, a first electrical line being insertable into the first spring force clamping connections respectively via a first line insertion opening assigned to the respective first spring force clamping connection, wherein the first line insertion openings are arranged on a same first line insertion side of the housing. Furthermore, the terminal block can have, for each first spring force clamping connection, a second spring force clamping connection assigned thereto. The terminal block is thus suitable for connecting a plurality of electrical lines. The first spring force clamping connections can be electrically separated from one another or partially or completely electrically connected to one another.

[0036] Here, the housing of the terminal can be a continuous housing in the arrangement direction, which accommodates a plurality or all of the first and second spring force clamping connections. The terminal can also be configured as a modularly assemblable terminal block, wherein a plurality of disc-shaped housing modules are arranged disc-shaped and side by side in the arrangement direction and are connected to one another. Such a housing module can then accommodate, for example, a first and a second spring force clamping connection, respectively. The housing modules can be locked to one another, for example, for example, via locking pins and locking recesses, wherein an end plate (cover) can be locked at the end of such a terminal block.

[0037] In the scope of the present invention, the indefinite article "a" is not to be understood as the numeral "one". When, for example, a component is mentioned, this is to be interpreted in the sense of "at least one component". If angle specifications are made in degrees, this relates to the circular measure of 360 degrees (360°). BRIEF DESCRIPTION OF DRAWINGS

[0042] Figure 4 a multipolar terminal block composed of a plurality of terminals. DETAILED DESCRIPTION

[0043] Figure 1 A terminal 9 is shown, which has a housing 3 and a first spring force clamping connection 1 for connecting a first electrical conductor and a second spring force clamping connection 2 for connecting a second electrical conductor. The first spring force clamping connection 1 and the second spring force clamping connection 2 are arranged in the housing 3.

[0044] ​The first spring-force clamping connector 1 has a first clamping spring 10 and a first mating support 19. A first clamping portion 18 is formed between the first clamping spring and the first mating support, at which a first electrical conductor can be fixedly clamped between the first clamping spring 10 and the first mating support 19. To fix the first electrical conductor, the first clamping spring 10 has a first clamping leg 13. A first spring bow 12 is connected to the first clamping leg 13. To fix the first clamping spring 10 in the housing 3, the first clamping spring 10 has a first support leg 11. The first support leg 11 is connected to the first spring bow 12 via a first connecting section 14.

[0045] The second spring-force clamping connector 2 has a second clamping spring 20 and a second mating support 29. A second clamping portion 28 is formed between the second clamping spring and the second mating support, at which the second electrical wire can be fixedly clamped between the second clamping spring 20 and the second mating support 29. To fix the second electrical wire, the second clamping spring 20 has a second clamping leg 23. A second spring bow 22 is connected to the second clamping leg 23. To fix the second clamping spring 20 in the housing 3, the second clamping spring 20 has a second support leg 21. The second support leg 21 is connected to the second spring bow 22 via a second connecting section 24.

[0046] The first support leg 11 is connected to the second support leg 21, for example, in that the first and second clamping springs 10 and 20 are configured as a single piece of metal.

[0047] The first clamping part 18 and the second clamping part 28 are disposed inside the housing 3, and are significantly spaced from the outer walls 33 and 34 of the housing 3. An inner wall 39 made of the housing material and extending in the longitudinal direction is provided inside the housing 3, and the inner wall is formed at one end of the first mating support 19 and the other end of the second mating support 29.

[0048] The housing 3 has a first wire introduction opening 31 through which a first electrical wire can be introduced into the housing 3 and led to a first clamping portion 18. The portion of the first electrical wire introduced there, with its insulation stripped, is then disposed in a first wire receiving space 35. The housing 3 has a second wire introduction opening 32 through which a second electrical wire can be introduced into the housing 3 and led to a second clamping portion 28. The second electrical wire is then disposed in a second wire receiving space 36.

[0049] For operating the first spring force clamping connection 1, the terminal 9 has a first operating element 4, which is for example designed as an operating press. For operating the second spring force clamping connection 2, the terminal 9 has a second operating element 5, which is for example designed as an operating press. The first operating element 4 and / or the second operating element 5 can be designed in one piece with the material of the housing 3, for example in one piece with the outer housing wall 34. The first operating element 4 serves for transmitting a manually applied operating force onto the first spring bow 12, whereby the first spring bow 12 together with the first clamping leg 13 can be deflected downwards, so that the first clamping point 18 opens. The second operating element 5 serves for transmitting a manually applied operating force onto the second spring bow 22, whereby the second spring bow 22 together with the second clamping leg 23 can be deflected downwards, so that the second clamping point 28 opens. Upon operating the respective operating element 4, 5, the operating element subsequently performs a small pivoting movement.

[0050] The terminal 9 can be designed for arranging and assembling with other terminals in a row direction in order to form a multipolar terminal block. For this purpose, a first locking element 38 can be molded on the housing 3 on one side, and a second locking element can be present on the opposite housing side, which is not visible in Figure 1 . For example, the first locking element 38 can be designed as a pin protruding from the housing 3, and the second locking element as a counterpart to the pin, i.e. in the form of a recess in the housing 3. In this way, a plurality of terminals 9 can be assembled into a terminal block by means of their housings 3 according to the Lego principle.

[0051] Figure 2 A metal piece is shown, which has a first clamping spring 10 and a second clamping spring 20. It can be seen that the first clamping leg 13 has a window-like first passage opening 15, through which a first electrical conductor is to be led. At the inner circumference of the first passage opening 15, a first clamping tab 16 is provided on the first clamping leg 13 and slightly bent away from the first clamping leg 13 in the direction of the first support leg 11. At the free end of the first clamping tab 16, a clamping edge 17 for clamping the electrical conductor can be provided, wherein the mounting angle of the free end of the first clamping tab 16 towards the first clamping edge 17 can be relatively small in order to avoid damage at the first electrical conductor. Furthermore, the second clamping leg 23 has a window-like second passage opening 25, through which a second electrical conductor is to be led. At the inner circumference of the second passage opening 25, a second clamping tab 26 is provided on the second clamping leg 23 and slightly bent away from the second clamping leg 23 in the direction of the second support leg 21. At the free end of the second clamping tab 26, a clamping edge 27 for clamping the second electrical conductor can be provided, wherein the mounting angle of the free end of the second clamping tab 26 towards the second clamping edge 27 can be relatively small in order to avoid damage at the second electrical conductor.

[0052] Figure 3 The connection terminal 9 is shown together with the first electrical conductor 61 clamped at the first spring force clamping connection 1 and the second electrical conductor 62 clamped at the second spring force clamping connection 2.

[0053] The first conductor accommodation space 35 is separated from the second conductor accommodation space 36 via a partition wall 37 constituted by the housing 3. The partition wall 37 simultaneously forms a stop for limiting the introduction depth of the first electrical conductor 61 and the second electrical conductor 62.

[0054] Figure 4 A terminal block assembled from a plurality of connection terminals 9 is shown. The open side of the last connection terminal 9 arranged in series is covered by an end plate 7 which can be locked to the housing 3 of the last connection terminal 9 in the same way as the individual housings 3 are locked to one another, i.e. with the first locking element 38.
