Background Technology

[0002] Document DE 10 2010 015 011 B4 discloses a lateral jumper device with a gripping element for tandem clamps, wherein the gripping element surrounds a metal bridging rail. A pivotally supported stop element is arranged on the gripping element, which limits the insertion depth of the lateral jumper device. Here, the passage to the operating opening for the clamping spring is blocked at the maximum insertion depth. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a horizontal jumper device that is as improved as possible.

[0004] The aforementioned technical problem is solved by a lateral jumper device or by a kit consisting of at least one conductor connector and a lateral jumper device.

[0005] Advantageous implementation methods are described in this application.

[0006] In this lateral jumper device, as proposed in the present invention, a blocking section is arranged on the insulator, the blocking section having a free end pointing in the insertion direction, and the blocking section being connected to the insulator via a connecting section.

[0007] A lateral jumper device is achieved by forming a blocking section on an insulator, which effectively prevents access to and / or manipulation of the operating mechanism of the spring-loaded terminal block in the inserted state. This operating mechanism can be, for example, an operating element such as an operating button, a pivotable lever, or an operating channel for inserting an operating tool. The free end of the blocking section pointing in the insertion direction ensures a compactly constructed lateral jumper device that effectively prevents access to and / or manipulation of the operating mechanism during the insertion process.

[0008] Preferably, the insulator, connecting section, and blocking section are designed as a single unit, especially integrally molded, so that the lateral jumper device can be manufactured conveniently and at low cost with fewer production steps. For example, the insulator, together with the connecting section and blocking section, can be made of electrically insulating plastic, for example by plastic injection molding, wherein the metal plug tongue and connecting bar can be advantageously encapsulated in the injection molding.

[0009] In a preferred embodiment, the blocking section and the plug tongue are oriented substantially parallel to each other. Therefore, it is preferable to form a U-shaped receiving portion by means of the blocking section and the plug tongue. Advantageously, a receiving space is achieved in the lateral jumper device, in which, in the inserted state, a section of the spring-loaded terminal or an element and / or section of the component belonging to the spring-loaded terminal can be space-savingly accommodated.

[0010] In a preferred embodiment, at least one segment of the insulator facing the conductive link sleeve-like portion surrounds one or more tongues. This effectively insulates the portions of the tongues extending into or from the housing housing the resilient terminal block, thereby improving electrical contact safety. Advantageously, each tongue has at least one contact area for electrical contact that is not surrounded by the insulator.

[0011] The longitudinal extension direction of the connector tongue is preferably consistent with the insertion direction, which allows for particularly simple installation of the lateral jumper device.

[0012] Furthermore, the kit assembly described at the beginning consists of at least one conductor connector and has at least one lateral jumper device. The conductor connector has a plurality of conductor terminals arranged side-by-side in an arrangement direction within an insulating housing. According to the invention, in the inserted state, the tongue of the lateral jumper device is electrically clamped and held onto the busbar in the clamped position, and a blocking section at least partially overlaps the insulating housing and the operating element, i.e., at least substantially preventing movement of the operating element. Advantageously, the blocking section thus effectively prevents the lateral jumper device from being easily and unintentionally removed from the conductor connector and / or the interruption of the electrical connection between two adjacent conductor connectors.

[0013] In a preferred embodiment, in the inserted state, at least one segment of the insulating material housing and at least one segment of the actuating element are arranged between the blocking segment and one or more tongues. This advantageously ensures that, in the inserted state, only the segments of the insulating material housing and the actuating element are arranged in the U-shaped receiving portion of the transverse jumper device, and thereby effectively overlaps the actuating element and the insulating material housing.

[0014] In a preferred embodiment, at least one actuating element is configured as a lever pivotally supported in an insulating housing, wherein at least one section of the actuating element is overlapped by a blocking section. This, in particular, can easily prevent outward pivoting movement of the advantageously operable pivotable lever. However, it is also conceivable to use a translatable control button, wherein the blocking section can effectively and simply prevent access to and operation of the control button.

[0015] In a preferred embodiment, the lateral jumper device electrically connects the first and second conductor clips to each other. This advantageously achieves the goal of electrically connecting the two conductor clips at the same potential, thereby increasing the number of conductor connections for that potential. This allows multiple conductor clips to be electrically connected to each other using another lateral jumper device of the same structure according to the invention.

[0016] In this invention, the indefinite article “one” is not understood as a quantifier. (The use of “one” or “a” as articles has been avoided in the Chinese translation.) Therefore, when referring to a component, it is understood as “at least one component.” If angular data is given in the unit “degree,” it is based on a circular dimension of 360 degrees (360°).

[0024] Figures 1 to 3 The first embodiment of the lateral jumper device 1 is shown, which has a first plug tongue 2a and at least one additional second plug tongue 2b. The plug tongues 2a and 2b are preferably made of a conductive metal, such as copper or a copper alloy, and are electrically connected to each other by a connecting strip 3. The plug tongues 2a and 2b and the connecting strip are preferably integrally formed or stamped from a sheet metal. The facing or near-the-connecting-strip sections of the connecting strip 3 and the plug tongues 2a and 2b are surrounded by insulators 4 and 4a made of an electrically insulating material, such as plastic. The plug tongues 2a and 2b extend along a common insertion direction S using their free ends not surrounded by the insulators 4. Alternatively, the lateral jumper device 1 may have more than two plug tongues 2a and 2b, such as three, four, or more plug tongues 2, all of which are advantageously electrically connected to each other. The plug tongues 2a and 2b themselves can have any shape and length, and are arranged substantially parallel and spaced apart from each other.

[0025] As can be seen, a blocking section 5 is arranged on the insulator 4. The blocking section 5 is connected to the insulator 4 via a connecting section 6. In this embodiment, the connecting section 6 has two spaced-apart connecting strips 7, wherein the number and shape or width of the connecting strips can be varied. The insulator 4, the connecting section 6, and the blocking section 5 are preferably integrally formed from the material of the insulator 4.

[0026] As can be seen, in this embodiment, the blocking section 5 is designed as a substantially flat, flat plate or tongue, wherein the free end 8 of the blocking section 5, away from the connecting section 6, points towards the insertion direction S. The blocking section 5 is arranged in a plane that is substantially parallel, i.e., slightly inclined at an angle of less than 10°, relative to the planes opened by the insertion tongues 2a and 2b. It is clearly shown here that a U-shaped receiving portion 9 opening towards the insertion direction S is formed between the blocking section 5 and the insertion tongues 2a and 2b. The U-shaped receiving portion 9 may widen along the insertion direction S.

[0027] In an alternative embodiment (not shown), it is conceivable to add a reinforcing insert made of metal or other materials into the blocking section 5 and / or the connecting section 6.

[0028] Figure 4An embodiment with a conductor connector device 10 is shown, which includes a first conductor connector 11 and a second conductor connector 11', which are preferably latched or clamped and housed in a common holder 12. The two conductor connectors 11, 11' are arranged adjacent to each other, preferably adjacent to each other, in the holder. Each conductor connector 11, 11' has a plurality of resilient terminals arranged side by side along an arrangement direction A, wherein each resilient terminal is provided with at least one conductor insertion port 13, 13' and a pivotable lever 14, 14'.

[0029] It can also be seen that the horizontal jumper device 1 is inserted into two adjacent or two adjacent conductor insertion ports 13, 13', wherein the first conductor insertion port of the adjacent conductor insertion port 13 is equipped with a first conductor connecting clip 11, and the second conductor insertion port of the adjacent conductor insertion port 13' is equipped with a second conductor connecting clip 11'. The horizontal jumper device 1 thereby electrically connects the first and second conductor connecting clips 11, 11' to each other. The plug tongues 2a, 2b are here clamped and fixed in the clamped position by corresponding spring terminals.

[0030] It can also be seen that the blocking section 5 of the horizontal jumper device 1 overlaps the adjacent closed operating levers 14 and 14' of the first and second conductor connecting clips 11 and 11'. This prevents the operating levers 14 and 14', which are connected by the blocking section 5, from moving from the closed position or pivoting to the open position when the horizontal jumper device 1 is plugged in. In the closed position, the clamping position of the spring terminal is closed, and in the open position, the clamping position of the spring terminal is open.

[0031] Figure 5 From and Figure 4 A perspective view of the opposite sides is shown. Figure 4 The conductor connection clamp device 10. It can also be seen here that the blocking section 5 of the transverse jumper device overlaps two adjacent or mutually adjacent operating levers 14, 14' and prevents pivoting movement.

[0032] Figure 6 Through with Figure 4A cross-sectional view consistent with section line BB shows the conductor connector 10 together with the inserted transverse jumper device. The conductor connectors 11, 11', clamped and / or locked in the clamping seat are also visible here. The conductor connectors 11, 11' have resilient terminals housed in an insulating housing 15, wherein the resilient terminals have clamping springs 17 held on a busbar 16. The clamping spring 17 has at least one clamping arm 18, which has a clamping edge 19 disposed on its free end. The clamping edge 19 and the busbar 16 opposite to it form a clamping position 20 for insertion of, for example, the electrical conductor to be clamped or the transverse jumper device 1, using tongues 2a, 2b. Here, the busbar 16 is designed to be continuous, such that it can electrically connect at least a plurality of resilient terminals arranged side-by-side along the arrangement direction A.

[0033] exist Figure 6 The diagram shows a lateral jumper device 1 with inserted conductor connector clips 11, 11', wherein one or more plug tongues 2a, 2b are inserted into or guided into the conductor insertion ports 13 of the conductor connector clips and pressed against the busbar 16 by the clamping arm 18 of the clamping spring 17. It can be seen that the conductive-facing section 4a of the insulator 4 sleeve-encloses one or more plug tongues 2a, 2b, located inside the conductor connector 11 in a conductor insertion channel connected to the conductor insertion ports 13, 13'. This arrangement ensures electrical safety because the conductive parts (plug tongues 2a, 2b) of the lateral jumper device 1 are inaccessible to the operator.

[0034] It can also be clearly seen that, in the plugged-in state of the lateral jumper device, the section of the conductor connecting clip 1, especially the section of the insulating material housing 15 of the conductor connecting clip 11, and at least the ends of the operating levers 14 and 14' that are away from the pivot axis of the operating levers 14 and 14' and are preferably designed as operating handles, are arranged inside the receiving portion 9 of the lateral jumper device 1. In particular, it can be seen that the blocking section 5 overlaps at least one section of the operating levers 14 and 14', such that this section of the operating levers 14 and 14' and the section of the insulating material housing 15 are arranged between the blocking section 5 and one or more plug tongues 2a and 2b. Therefore, the blocking section effectively prevents or inhibits the operation of the operating elements 14 and 14' and thereby prevents or inhibits their pivoting, and also prevents or inhibits the opening of the clamping position 20 of the spring terminal. Here, a certain clearance of the operating levers 14 and 14' can be achieved without canceling the clamping action. This prevents the easy and unintentional removal of the transverse jumper device 1 from the conductor connectors 11, 11' and / or the interruption of the electrical connection between two adjacent conductor connectors 11, 11'.

[0035] The slightly widened receiving portion 9 along the insertion direction S makes it easier to insert the transverse jumper device 1, because the inner wall of the blocking section 5 facing the receiving portion 9 can serve as an insertion ramp for the sections of the conductor connecting clips 11, 11', especially the operating lever 14 and / or the insulating material housing.
