    Description: [0001] The invention relates to a bridging device for a meter terminal according to the preamble of claim 1. Such a bridging device has become known, for example, from the subject matter of DE 10 216 913 A1. The bridging device shown there consists essentially of a self-contained bracket, on whose underside electrically conductive contacts are arranged, which are designed as blade contacts. In the case of application of the bridging device, this is plugged onto the top of a meter connection terminal and the blade contacts reach through slots in the cover of the terminal and contact the arranged in the interior of the housing spring contact strips.
    Purpose of the lock-up device is to allow an exchange of a connected to the terminal block of the meter terminal energy meter, without causing a power interruption.
    For this purpose, the bridging device bridges with its bridging contacts the connected counter by the blade contacts of the lock-up device make a conductive connection with the terminals and thereby cause a bridging of the connected meter.
    A similar subject matter is apparent from DE 2 256 373 B2, in which a bridging device shows U-shaped staples at the bottom, which bridge the bridging distance between the counter and the counter output.
    In both documents, there is the disadvantage that the lock-up device is placed only loosely on the terminal block and it must be ensured that the arranged on the underside of the lock device blade contacts engage in the terminal-side spring contacts.
    The assignment of layers is therefore only by the insertion of the bridging contacts in the terminal-side contacts. Further holding forces do not exist. In particular, a position secured position is missing.
    It may even happen that the lock-up device is tilted or not completely placed on the lid of the terminal housing.
    An even greater risk is that because of the unsafe position assurance of the bridging device - because the holding force is given solely by the contact of the bridging contacts - there is a risk that are brought to the housing of the terminal during disassembly of the power meter vibrations, thereby There is the danger that the electrical contacts of the bridging device come into external contact with the connection contacts in the housing and there is an uncontrolled interruption of the power supply.
    The result is that an arc can occur and the fitter, who is busy with the dismantling of the energy meter, can be injured by the resulting arc.
    With the subject matter of DE 10 2014 101 067 B3, the bridging device for a meter terminal for bridging a meter connected to the meter terminal is known, wherein in the housing of the meter terminal a number of electrically conductive terminal blocks are arranged, the contactable with the bridging contacts of the bridging device are when the lock-up device is mounted on the housing of the meter terminal, wherein a locking or jamming between the lock-up device and the housing of the meter connection terminal is arranged on both sides of the side surfaces of the lock-up device and cooperates with locking projections on the housing and / or on the lid.
    The document describes a so-called lock prevention arrangement, which is necessary in electricity meter connection systems with bridging plug in the event that when plug-in terminals are used, the jumper plug can only be snapped onto the terminal block when no electricity meter is plugged. The insertion tab located on the electricity meter prevents latching of the locking element on the bridging plug as soon as the electricity meter is plugged onto the terminal block. A manual release is not provided in this document. The locking device works with two spring-loaded swiveling pawls that do not allow manual operation. Locking takes place automatically when plugging the jumper plug into the terminal block when no electricity meter is plugged in. The unlocking is done by hand.
    Disadvantage of this arrangement is the arrangement of compression springs which bias the spring-loaded pivotable detents. Such compression springs can be lost or broken as separate parts. In case of failure, the lock is unusable.
    Another disadvantage is the poor accessibility of the locking pawls, the free, pivotal ends can be found only by palpation of a lateral recess on the terminal block.
    The invention is therefore based on the DE 10 2014 101 067 B3 the object of developing a lock-up device for meter connection terminals of the type mentioned so that the lock-up device can be handled easier and more reliable.
    To solve the problem, the invention is characterized by the technical teaching of claim 1.
    Feature of the invention is that a manual latching and unlatching between the lock-up device and the housing of the terminal is given and the latching device is formed from a respective latch, which consists of a one- or two-armed lever whose spring-elastic pivot bearing as a flexible connecting part is formed on the plastic material of the lock-up device.
    This has the advantage that the considered disadvantageous springs for producing the spring preload can be omitted on the pivot bearings of the pawls and a given by the bendable plastic material of the connecting part preload acts both in the opening direction and in the closing direction of the locking pawls. Another advantage is that the latches are material integral with the plastic material of the bridging plug and thus the arrangement of separate latches can be omitted with associated pivot bearings.
    In a first preferred embodiment, it may be provided that the latching device is arranged in each case on the two opposite narrow sides of the approximately bow-shaped bridging device and the latching projections on the side surfaces of the housing, e.g. on the cover or on a circumferential or partially existing edge of the housing, are provided. Thus, the locking device is easily accessible and can be both locked and unlocked by hand.
    In a kinematic reversal to the above solution, it is provided that the latching device is arranged on the side surfaces of the housing and the latching projections are respectively arranged on the narrow side of the bow-shaped bridging device.
    In a preferred embodiment, it is provided that the locking device is designed as a two-armed lever, which means that a lever part serves as a handle and the pivot bearing of the lever is formed as a bendable part on the side surface of the lock-up device and the other part at his free end carries the latching hook.
    Instead of a two-armed latching device, it may also be provided in another embodiment, this latching device einarmig form.
    In a preferred embodiment, it is provided that the bridging device consists of an approximately mirror-symmetrical part, which consists of a transverse part, on both sides mutually mirror-symmetrical arcuate parts of the sheet are formed.
    The purpose of this measure is that the lock-up device can be taken to operate with the terminal only with two hands, with one hand, the locking device on one side and the other hand, the locking device operated on the opposite side to avoid in that the bridging device is actuated with only one hand, which can lead to incorrect operation. It is therefore a deadman operation, because it is ensured by the bent-out parts of the bow on the bridging device that only one locking device can be operated with one finger at a time by the fingers.
    For this purpose, the arch parts each have inner abutment surfaces which are formed approximately in the same radius of curvature, as the abutment surface associated with this, opposite stop surface on a lever part which is designed as a handle of the latching device.
    Accordingly, the latching device is formed in a preferred embodiment as a two-armed lever, of which a lever is the handle, and the pivot bearing of this lever is molded as a bending part in the form of a bendable pin-shaped connecting part to the plastic material of the bridging device.
    Thus, the one lever part continues in training as a handle on the pivot bearing away as the lower hook part, and at the free lower end of this hook part of the inwardly directed latching hook is arranged.
    In a preferred embodiment, it is provided that these latching hooks engage a lateral latching edge of the housing.
    In another embodiment, it may be provided that takes place instead of a latching on the edge of the housing, a latching on the underside of the lid of the housing.
    In another modified embodiment, it may also be provided that the bridging device is not formed with two oppositely directed parts of the sheet, but forms a self-contained bow member defining a central inner and self-contained recess, which is for the penetration is determined with one hand.
    Important in all embodiments is that the lock-up device only allows a two-handed operation, because the respective locking device is formed in each case mutually opposite sides symmetrical to each other and can be operated only with one hand.
    In the following the invention will be explained in more detail with reference to several execution paths representing drawings.
    It shows:

    9 shows the locking principle of the lock-up device according to the embodiment of FIGS. 1 to 8,
    Fig. 10: a comparison with FIG. 9 modified example of a locking device.
    1 to 7, the bridging device 1 consists of an electrically insulating plastic, in the bottom surface of the associated bridging contacts 15 are embedded in the form of embedding 29.
    It is important that the bridging contacts 15 do not form an electrically conductive connection with each other, as is known in the prior art. In this known arrangements, there is a current-conducting connection between the individual bridging contacts 15. This has the disadvantage that in the case of bridging high current flows are given by the bridging device 1, which are connected to an undesirable heating of the lock-up device 1, in this case also arise undesirable increased power losses.
    In the inventive singular and insulating embedding of the bridging contacts 15 in the form of embedding 29 in the plastic material of the bridging device 1, no current flows between the bridging contacts 15 and thus a significant increase in operating safety and a reduction of current flows is connected.
    In the illustrated embodiment, the bridging contacts 15 consist of blade contacts, which are formed only in a single embodiment of a solid material and have front tips.
    In other embodiments, other forms of bridging contacts 15 may be used.
    The bridging device 1 consists essentially of a central part 13, which is elongated and at its two opposite ends in each case outwardly directed arch parts 14 are formed.
    Each arch part 14 forms on its underside a stop surface 26 which is arranged in the region of an arc surface 27.
    In each case on the opposite narrow sides of the bridging device 1, the inventive locking device 7 is formed. After the locking devices 7 are formed the same on both sides, the description of a single locking device 7 is sufficient.
    In another embodiment, it may be provided that the inventive locking devices 7 are arranged on the front and back of the lock-up device.
    Each locking device 7 consists in the illustrated embodiment of a connecting part 9, which is integrally formed on the side wall of the lock-up device 1. The connecting part 9 forms the pivot bearing for a two-armed lever, in which a lever part is designed as a handle 10 and the other lever part is designed as a hook part 25, which adjoins the pivot bearing 8.
    By finger pressure on the arcuate finger recess 11 this is in the direction of arrow 22 (see Fig. 4) with the associated inner stop surface 28 against the device-side stop surface 26 moves until it abuts there. Upon actuation of the latching device, the arch part 14 can be pulled upwards at the same time.
    During this movement, the latching hook 12 is brought out of engagement with its latching projection in the direction of arrow 23 and the lock-up device can be pulled off at the same time upwards.
    The housing of the terminal consists essentially of a self-contained housing 3 made of an insulating plastic material, in the interior of a number of terminal blocks 4 are arranged, which consist of an electrically conductive material.
    On the one side of the terminal blocks 4, the connection sides for the cable connections are arranged in the form of electrical conductors, while at the opposite side of the counter pins are inserted and clamped there.
    The housing is sealingly closed by a lid 2, in the upper side a number of slots 16 are arranged, through which engage the knife-like bridging contacts 15 of the lock-up device 1.
    The terminal blocks 4 consist of a number of isolated from each other and separated by partitions arranged one another terminals 5, which consist of an electrically conductive material.
    The locking device 7 of the lock-up device 1 shown locked with a side grid edge 6 on the outside of the housing. 3
    Fig. 2 shows the locked state, where it can be seen that the latching hooks 12 of the spaced-apart locking devices 7 engage under the latching edge 6 of the housing 3.
    3 to 7 show the various views of the arrangement of FIG. 2, where the same parts have been given the same reference numerals.
    It can be seen that the latching hook 12 extends beyond the side surface of the housing 3 and in Fig. 7, the view is also shown on the bottom side 19 of the housing.
    From Figs. 3 and 5 shows that the locking device 7 is not symmetrical attaches to the side surface of the housing 3, but that a lateral offset is present.
    The bridging of the terminal blocks 4 takes place in that the bridging contacts 15 of the lock-up device 1 in the associated terminal-side contact slots 17 between the individual electrically isolated terminals 5 engage and establish an electrically conductive connection between adjacent terminals 5, which on both sides of the respective Contact slot 17 are arranged.
    Fig. 1 also shows that the bridging device 1 may be connected at its bottom with a test pin 18 which engages in an associated test opening in the lid 2 and is contactable with a special terminal 5.
    Fig. 8 shows a further embodiment of a 'bridging device 21, that instead of the oppositely disposed middle parts 11, which are each bent outwards and partially overlap the locking device 7, instead of a bracket member 24 may be provided, which is a in closed recess 20 defined. The locking device 7 is no longer covered in this case by an arch member 14, but arranged freely on the outer surface of the lock-up device 21.
    Otherwise, the same explanations apply to the same parts.
    Fig. 9 shows the locking principle of FIGS. 1 to 8, where it can be seen that is pivoted by finger pressure on the arcuate handle 10 in the direction of arrow 22 of the hook member 25 in the direction of arrow 23 to the outside and outward engagement with the locking edge. 6 comes.
    Fig. 10 shows the modification to the Fig. 9, where it can be seen that the locking device 7a may be formed as a one-armed lever. In this case, the hook portion 25 continues with a handle 10 down and the disengagement of the latching hook 12 must be accomplished by the spring member is pulled in the direction of arrow 23 against the spring force of the connecting part 9 to the outside.
    The invention is not limited to the locking device shown. Instead of a locking device and clamping connections between the lock-up device and the housing of the terminal can be used.
    A preferred embodiment of a clamping connection is given in the form that in each case on the narrow sides of the lock-up device, a rotary shaft is arranged, which is rotatably mounted in the lock-up device and - with respect to FIG. 1 - is vertically aligned. The upper end of the rotary shaft is rotatably connected to a suitable handle, while the lower end of the rotary shaft is rotatably connected to a clamp eccentric. Thus, the clamp eccentric is pivotable upon rotation of the shaft in an open position and in a clamping position. In the open position, the clamp eccentric outer engagement with an associated housing edge 6 on the housing 3, while in the closed position, the clamping surface of the clamp eccentric engages under the housing edge 6 of the housing 3.
    In the arrangement of two spaced-apart rotary shafts, each with a handle and a clamp eccentric ensures that such an arrangement is operated simultaneously with two hands.
