Description

The invention relates to a connecting device for connecting a shield clamp with a rail element according to the preamble of claim 1.

Such a connection device can be attached along a Ansetzrichtung to a rail element, in order to connect the connecting device with the rail element in this way. For example, a shield terminal can be connected to the connection device so that the shield terminal can be fixed to the rail element via the connection device.

A shield terminal is used to contact a shielding conductor, for example in the form of a line core of the electrical line surrounding the shielding braid, with a leakage potential, in particular a grounding potential - for example a busbar, a mounting rail or a housing wall of an electrical system (e.g., a control cabinet). In this case, the contacting should be resistant, in particular resistant to temperature and corrosion (even in an aggressive environment), in order to produce reliable earthing of the shielding conductor over the service life of an electrical system.

Rail elements may be in different shapes. For example, a so-called C-rail may have inwardly facing edge portions forming a slot opening therebetween. In contrast, other rail elements can be designed, for example, as a mounting rail with outwardly directed edge sections.

It is desirable to attach a shield clamp to such a rail element, a connection device that is simple in construction, easy to manufacture and also easy to handle.

At one of the DE 10 2009 057 514 B3 provided connection device, a shielding cable can be set via a clip element on a clasp. The clip can be locked to a mounting rail.

The DE 103 15 668 B4 discloses a terminal with a bus bar and a socket portion for latchingly securing to a mounting rail.

One from the DE 199 49 508 B4 Known device for fixing a shield clamp has a body with feet for latching connection with a mounting rail.

Object of the present invention is to provide a connecting device for connecting a shield clamp with a rail element available, the simple structure, thereby easy to manufacture and also easy to handle.

This object is achieved by an article having the features of claim 1.

Accordingly, the connecting device has a first locking element with a first locking leg and a second locking element with a second locking leg. The first latching element and the second latching element are at least partially parallel to each other along a direction of movement and connected to each other such that the first latching element and the second latching element along the direction of movement are mutually movable to positively connect the connecting device via the latching elements with the rail element or of to solve the rail element.

The connecting device thus has two mutually movable locking elements, each having (at least) a locking leg. For example, a first latching device in the form of a first latching projection or the like may be formed on the first latching leg, while a second latching device is formed on the second latching latch, for example in the form of a second latching projection. The locking legs together serve for latching connection of the connecting device with edge portions of a rail element, for example in the form of a C-rail with inwardly facing edge portions or a mounting rail with outwardly facing edge portions.

The latching elements are at least partially parallel to each other along the direction of movement extends to each other while moving along the direction of movement. When attaching the connecting device to an associated rail element, the locking legs of the locking elements can thus be moved against each other, so that the connecting device can snap latching with the rail element in engagement. Likewise, the locking elements for releasing the connection of the connecting device can be moved with the rail element to each other, so that the positive connection of the connecting device is lifted with the rail element and the connecting device can be removed against the Ansetzrichtung of the rail element.

The Ansetzrichtung can in principle be rectilinear or curved. Along the Ansetzrichtung the connecting device can be attached to the rail element, while the locking legs of the locking elements latchingly engage with the rail element in engagement. For example, the connecting device can be pivoted onto the rail element by first attaching one of the latching elements to an associated edge portion of the rail element, in order then to pivot the connecting device towards the rail element and thereby also bring the other latching element into engagement with the rail element.

In one embodiment, the first locking element and the second locking element are connected to each other via a connecting portion. The connecting portion may for example be formed integrally with both the first locking element and with the second locking element. In this case, the connecting section can be bent over at least in sections (by approximately 180 °) for connecting the first latching element to the second latching element. For this purpose, the connecting portion is formed, for example, at a first end of the connecting device, while the (at least partially along the direction of movement parallel to each other) locking elements on a (along the direction of movement) remote from the first end, the second end of the connecting device are not interconnected.

In a particularly advantageous embodiment, the connecting device is manufactured as a one-piece component, with integrally interconnected via the connecting portion locking elements. The connecting device can be manufactured, for example, as a stamped bent sheet metal part, for example, from a steel material, for example a spring steel, so that in particular an elastic connection between the latching elements is produced via the connecting section. Integral production of the connecting device as a one-piece component results in a particularly simple construction, which is simple and inexpensive to manufacture and easy to handle both during assembly and during its intended use.

In one embodiment, the second latching element is guided along the direction of movement on the first latching element. A movement of the locking elements to each other thus takes place in a defined manner along the direction of movement, so that the locking elements along a defined trajectory are guided in a guided manner to each other.

For this purpose, the first latching element, for example, a first guide means and the second latching element have a guided on the first guide means positively along the direction of movement, second guide means. One of the guide means may for example be formed by a guide slot in which the other, for example, formed as a guide projection guide means is slidably guided. For example, a guide means formed as a guide slot may be formed by stampings on the locking leg of the associated locking element, while the guide means of the other locking element is formed by a punched, engaging in the guide slot guide nose.

The latching elements are movable relative to one another along the direction of movement and are preferably guided relative to one another via the guide devices such that the movement takes place in a guided manner. The way by which the latching elements are movable relative to each other is limited in this case by stops, for example, so that the latching elements can only be adjusted by a certain distance relative to one another. Excessive deflection of the locking elements to each other is avoided in this way.

In one embodiment, the first latching element and / or the second latching element, viewed in a plane perpendicular to the direction of movement, a U-shape. The second locking element is in this case, for example, at least partially bordered by the first locking element, so that there is a nested arrangement of the locking elements.

By way of example, the first latching element can have two first latching limbs extending parallel to each other, each with a first latching device for connection to the rail element and a first base connecting the first latching limbs with one another. The locking legs extend perpendicularly from the base and form in this way together with the base of the U-shape of the locking element. About the locking legs on which locking devices, for example in the form of locking projections are formed, the positive connection of the connecting device is made with the rail element.

The second latching element is in this case preferably arranged between the latching limbs of the first latching element and movable between the latching limbs of the first latching element (in a guided manner). The first latching element thus grips the second latching element at least partially.

The second latching element may in this case have two second latching legs and a second base connecting the two second latching legs, so that the second latching element also has a U-shaped basic shape. At the second locking legs second locking devices are formed, for example in the form of locking projections, which together with the first locking means of the first locking legs of the first locking element produce the positive connection of the connecting device with the rail element during attachment and thus hold the connecting device form-fitting manner on the rail element.

Preferably, the second base of the second detent element extends parallel to the first base of the first detent element. The second latching element is thus arranged within the first latching element and aligned with its second base along the first base of the first latching element. The locking elements are movable relative to each other along the direction of movement, so that in this way the locking legs can be adjusted to each other and thereby, for example, the connecting device can be released by canceling the positive connection of the rail element.

In one embodiment, a guide edge is formed on each first locking leg of the first locking element and on each second locking leg of the second locking element, which is obliquely to Ansetzrichtung along which the connecting device can be attached to the rail element, and thus a ramp to facilitate the attachment of the Connecting device provides to the rail element. When attaching the connecting device to the rail element, the guide edges slide, for example, at edge portions of the rail element, so that thereby the locking legs are automatically adjusted to each other and the connecting device snaps into engagement with the rail element. When attaching the connecting device to the rail element thus no actuation of the locking elements is required. A deflection of the locking legs to each other Manufacture of the positive connection takes place automatically when applying by interaction of the leading edge with the rail element.

In the attached position, the connecting device is preferably connected to one or more height stops, which are formed on one or both locking elements, on the rail element, so that when the connecting device is set, the position of the connecting device to the rail element is defined in the direction of attachment. In particular, the connecting device can only be moved in the direction of attachment to a position in which the height stops are in contact with the rail element.

The height stops can be formed for example on the first locking legs of the first locking element.

In one embodiment, the first latching element has a first tool engagement and the second latching element has a second tool engagement. The tool engagements may be formed in particular at the second end of the connection device which is remote from the first end of the connection device (at which the connection section interconnects the latching elements) and make it possible to exert a relative force between the latching elements by applying a tool to the tool engagements. Thus, by means of a tool, for example a screwdriver, can be intervened together in the tool engagement to effect in this way a relative force between the locking elements along the direction of movement, so that in this way using a tool, the locking elements along the direction of movement can be adjusted to each other to release the connecting device from the rail element and to cancel the positive engagement of the locking legs with the rail element.

The connecting device can be connected, for example, with a shield terminal. Such a shield terminal may have, for example, a housing and a spring element arranged pivotably on the housing. An electrical lead may be attached to the housing with a stripped shield conductor to electrically contact the housing by clamping action of the spring member. About the connecting device of the shield conductor of the electrical line can thus be contacted with the rail element electrically, so that the Umbrella conductor, for example, can be placed on a ground potential of the rail element.

Such a connection device can be configured for attachment to different types of rail elements, such as a C-rail with inwardly facing edge portions or a support rail with outwardly facing edge portions. Via the connecting device, a shield terminal can be fixed to the rail element, in order to effect in this way an electrical contacting of a shield conductor of an electrical cable connected to the shield terminal with the rail element.

Fig. 1 to 11 show an embodiment of a connecting device 1 in the form of a snap-in foot, which can be connected to a rail element 3 in the form of a so-called C-rail and a shield clamp 2 carries, so by attaching the connecting device 1 to the rail element 3, the shield terminal 2 electrically connected to the rail element. 3 contacted and thus connected to the shield terminal 2 electrical conductor 40 can be brought to the potential of the rail element 3.

A shield clamp 2 serves a shield conductor 40 of an electrical line 4, shown schematically in FIG Fig. 2 electrically contact to bring in this way the shielding conductor 40 to a leakage potential, in particular a ground potential. The electrical line 4 has an electrically insulating sheath 41 which surrounds the shielding conductor 40. In the electrical line 4, for example, cable cores are enclosed, can be transmitted via the electrical signals, for example, data signals. The shielding conductor 40 may, for example, take the form of a shielding braid and envelops the enclosed in the electrical line 4 line wires for the purpose of electromagnetic shielding.

The shield conductor 2 has in the in Fig. 1 to 11 illustrated embodiment, a housing 20 on which a spring element 21 is pivotally mounted about a pivot axis S. The housing 20 has an upper part 200, which carries the spring element 21, a side wall 201 and an attachment flange 202 angled to the side wall 201, via which the shield clamp 2 is connected to the connection device 1, and defines a receiving space into which the electrical line 4 can be inserted with a stripped portion of the shielding conductor 40, so that the shielding conductor 40 can be contacted via a clamping leg 211 of the spring element 21 by clamping with a bearing surface 22 of the shield terminal 2. Via an actuating limb 210, the spring element 21 can be pivoted along a pivoting direction P to the housing 20, in this way the spring element 21 between a release position, in which the electrical line 4 can be inserted into the housing 20, and a clamping position, in the the shielding conductor 40 is contacted in a clamping manner electrically with the support portion 22 to adjust.

The shield terminal 2 is fixed to the connecting device 1 and can thus be applied via the connecting device 1 for the purpose of electrical contacting to the rail element 3 in the form of a C-rail. The rail element 3 has a base 30 as well as angled to the base 30, lateral legs 31, 32, of which edge portions 33, 34 are folded inwardly facing each other. Between the edge portions 33, 34, a slot opening 35 is formed, in which the connecting device 1 can be used for latching connection with the rail element 3.

If the connection device 1 is attached to the rail element 3, then the shield terminal 2 and above it an electrical line 4 connected to the shield terminal 2, in particular its shielding conductor 40, is electrically connected to the rail element 3.

The connecting device 1, in the illustrated embodiment, two locking elements 10, 11, which - considered in one of the plane in Fig. 9 corresponding level Q - each U-shaped and connected via a (bent by approximately 180 °) connecting portion 12 at a first end of the connecting device 1 with each other, as for example FIGS. 7 and 8 is apparent. Each locking element 10, 11 has two lateral locking legs 100, 110, which, as shown in the frontal view Fig. 9 can be seen, connected to each other via a base 101, 111 for forming the U-shape. At the remote from the connecting portion 12, the second end of the connecting device 1, the locking elements 10, 11 are not connected to each other and thus free from each other.

In the illustrated embodiment, a first, outer latching element 10 includes a second, inner latching element 11. The latching elements 10, 11 are in this case along a direction perpendicular to the plane Q direction of movement B slidably guided together by guide means 113 in the form of laterally formed on the base 111 of the second, inner latching element 11 guide slidingly sliding guide means 103 in the form of guide slots formed by stampings inside the locking leg 100 of the first outer latching element 10 slide and thereby create a longitudinal guide of the second, inner latching element 11 to the first, outer latching element 10. The second, inner latching element 11 is thus movable in the direction of movement B to the first, outer latching element 10 to allow in this way, as will be explained below, the manufacture and release of the positive connection of the connecting device 1 with the rail element 3.

The path of the second, inner latching element 11 to the first outer latching element 10 is limited by stops 109A, 109B on both sides of the formed by the stampings, the guide means 103 forming guide slot so that the second, inner latching element 11 only over a predetermined path relative to the first, outer locking element 10 can be moved.

On the locking legs 100 of the first outer locking element 10 locking devices 102 are formed in the form of locking lugs on one side, as is apparent from FIGS. 7 and 8 is apparent. On the locking legs 110 of the second, inner locking element 11 are opposite locking devices 112 also formed in the form of locking lugs. These locking devices 102, 112 together serve to produce a positive connection with the rail element 3 when the connecting device 1 is attached to the rail element 3.

Each locking leg 100, 110 also has, at an edge portion adjoining the respective latching device 102, 112, a leading edge 107, 117 directed obliquely to an attachment direction E, which serves as a run-on slope. In the Ansetzrichtung E, the connecting device 1 can be attached to the rail element 3, so that when attaching the connecting device 1 to the rail element 3, the locking legs 100, 110 with their leading edges 107, 117 with the inner, the guide slot 35 bounding edges of the edge portions 33, 34 of the rail element 3 in abutment and thereby the locking legs 100, 110 pressed along the direction of movement B to each other, under elastic displacement of the locking elements 10, 11 along the direction of movement B to each other and under (minor) deformation of the connecting portion 12. The connecting device 1 thus comes with their Locking legs 100, 110 into engagement with the guide slot 35 of the rail element 3, wherein the locking legs 100, 110 snap back into their (relaxed) starting position as soon as the locking devices 102, 112 in the form of locking lugs, the edge portions 33, 34 have passed, so that the locking legs 100, 110 to the manufacture len a positive connection with the edge portions 33, 34 engage, as for example in Fig. 1 and 2 is shown.

The position of the connecting device 1 along the Ansetzrichtung E on the rail element 3 is defined here by height stops 106 on the locking legs 100 of the first, outer latching element 10. In the attached position, the height stops 106 are on the upper side in contact with the edge portions 33, 34 of the rail element 3, as for example Fig. 2 is apparent.

If the connecting device 1 is again to be detached from the rail element 3, then a tool 5, for example in the form of a screwdriver, can be attached to tool interventions 105, 115 on end sections 104, 114 of the latching elements 10, 11 remote from the connecting section 12, like this in Fig. 8 is shown. The tool 5 engages the tool engagement 115 formed as an engagement opening on the base 111 of the second, inner latching element 11 and is also supported on the tool engagement 105 on the base 101 of the first, outer latching element 10, so that by operating the tool 5 in an actuating direction A the second, inner locking element 11 can be adjusted in the direction of movement B to the first outer locking element 10, thereby the locking legs 100, 110 are moved towards each other with their locking devices 102, 112 and thus the positive connection of the connecting device 1 with the rail element. 3 will be annulled.

When releasing the connection, the locking legs 112 of the second, inner latching element 11 also reach with the edge portions 116 remote from the latching devices 112 in abutment with the opposite edge portion 34 of the rail element 3 (see, for example Fig. 4 ), so that also an excessive deflection of the locking elements 10, 11 is avoided to each other. These edge portions 116 may be (largely) rigid or elastically resilient.

The connecting device 1 is, in the illustrated embodiment, as a one-piece component, for example, as a stamped sheet-metal bent part made. The connecting device 1 can be made, for example, from a steel material, for example a spring steel, and is electrically conductive, so that the shielding terminal 2 can be electrically contacted with the rail element 3 via the connecting device 1.

At the base 101 of the first, outer latching element 10 upwardly projecting connection tabs 108 are arranged, via which the shield terminal 2 can be fixed to the base 101 and connected to the connection direction 1 above.

The fact that the connecting device 1 is manufactured as a one-piece component, results in a simple production as well as easy handling under normal use.

Due to the guidance of the locking elements 10, 11 via the guide means 103, 113 to each other, the locking elements 10, 11 (only) along a defined trajectory to each other to be moved. Due to the limitation of the movement path over the stops 109A, 109B along the direction of movement B in this case an excessive deflection of the locking elements 10, 11 to each other is prevented.

The connecting device 1 of the embodiment according to Fig. 1 to 11 is designed for attachment to a rail element 3 in the form of a C-rail. The connecting direction 1 can be correspondingly attached to a slot opening 35 of such a C-rail to lock in the slot opening 35. An in Fig. 12 to 19 illustrated embodiment of a connecting device 1 is in contrast to connect to a rail element 3 in the form of a mounting rail with outwardly facing edge portions 33, 34 is formed, as for example FIGS. 12 and 13 is apparent. Components with the same function are provided here in the figures with the same reference numerals.

In the embodiment according to Fig. 12 to 19 In turn, a first, outer latching element 10 and a second, inner latching element 11 are connected to each other via a connecting portion 12 and along a direction of movement B to each other. The second, inner latching element 11 is in this case performed on each locking leg 100 of the first, outer latching element 10 via two guide means 103 in the form of formed by stampings, along the direction of movement B spaced guide slots.

The latching limbs 100, 110 of the latching elements 10, 11, which are connected to one another via a base 101, 111, in turn each have a latching device 102, 112, which in the exemplary embodiment illustrated, due to the design of the rail element 3 with outwardly directed edge sections 33, 34. to point to each other, as for example Fig. 13 is apparent. In an attached to the rail element 3 position of the connecting device 1, the locking devices 102, 112 are positively engaged with the edge portions 33, 34 in engagement, so that the connecting device 1 is positively fixed to the rail element 3. About height stops 106 on the first, outer locking element 10, the position of the connecting device 1 on the rail element 3 along the Ansetzrichtung E hereby defined by the height stops 106 are on the upper side with the edge portions 33, 34 of the rail element 3 in Appendix.

When attaching the connecting device 1 in the Ansetzrichtung E to the rail member 3, the locking legs 100, 110 slide on outer edges of the edge portions 33, 34 so that the locking devices 102, 112 along the direction of movement B are removed from each other and the edge portions 33, 34 in Grab the procedure. To release the connection, in turn, a tool on tool engagements 105, 115 of the locking elements 10, 11 are applied to adjust in this way the second, inner locking element 11 in the direction of movement B to the first, outer locking element 10 and about the positive connection of Connecting device 1 with the rail element 3 to solve.

Incidentally, the operation of the connecting device 1 of the embodiment according to Fig. 12 to 19 analogous to the operation of the embodiment according to Fig. 1 to 11 , so that reference should also be made to the preceding statements. As in the embodiment according to Fig. 1 to 11 is also according to the embodiment Fig. 12 to 19 at the base 101 of the first, outer latching element 10, a shield terminal 2 is arranged, via which an electrical line can be connected to a shield conductor in an electrically contacting manner and thus electrically connected to the rail element 3.

In both embodiments, the locking legs 102, 112 may be resilient in itself or (largely) rigid.

The idea underlying the invention is not limited to the embodiments described above, but can in principle also be implemented in a completely different manner.

A connection device of the type described here can serve to connect a shield clamp with rail elements of completely different types.

In principle, the connecting device is not only suitable for connecting a shielding conductor to a rail element, but can also be used to connect another terminal for connecting other electrical conductors to a rail element.
