Description

Shield sheet Description

The invention is based on a shield plate according to the preamble of the independent claim 1.

Such shield plates are used in connectors, which are required to transmit currents and / or signals. The currents and / or signals are transported by a conductor to the connector. The conductor has at least one core. For a trouble-free transmission, the conductor is a shielded conductor. The shield serves the

Potential equalization. For the effective dissipation of potentially occurring interference on the cable shield as frequent and / or large contact surface of the cable shield is necessary.

US 5,895,291 A shows a cable gland for a

Plug connector with attached shield connection. The shield connection consists of two gutter-shaped elements. These are equipped on the side facing the conductor with a locking option. To the

Close the two halves are pressed together, thus close tubular to the conductor and hook in a locking option.

In DE 10 2008 037 030 B3 an electromagnetic shield for an electrical connector is disclosed, as well as the associated

electrical connectors. The electrical connector has two screen parts which can be connected to one another, wherein a region of the one screen part and a region of the other screen part overlap in an overlapping section.

A disadvantage of the known possibilities is that they do not guarantee the shield transfer directly in / on the connector. Furthermore, the known solutions can be used only with the use of tools such as screws, cable ties or Crimpbereichen. In addition, for example, crimped shield connections are not non-destructive solvable. However, an incorrect screen transfer leads to an unwanted, disturbed transmission of the currents and / or signals, which in turn can lead to a faulty function of a connected device. Another disadvantage of previously known shielding plates is that the screen transfers can not be adapted to different conductor cross-sections, so always the appropriate shield transfer for a

trouble-free transmission must be selected.

task

The object of the invention is to propose a shroud, which is a simple, reversible, variable and robust

Shield contact ensures an electrical conductor.

The task is characterized by the characterizing features of

independent claim 1 solved.

Advantageous embodiments of the invention are specified in the subclaims.

The present invention relates to a shroud. It has a plug-in page. The plug side is used to make contact with the

Connector with a mating connector.

The plug side opposite has the shield plate a

Connection side on. The connection side is used to connect at least one electrical conductor. Preferably, the connection side is used for

Connecting at least one electrical, shielded conductor. The conductor can be received in a contact element. In which

Contact element may be, for example, a crimp contact. The at least one contact element is receivable in the shielding plate and contacted with this, so that a secure

Screen transfer is guaranteed.

The shield plate is made of a conductive material, preferably a metal. Alternatively, the shroud is made of a plastic coated with a conductive alloy. The shielding plate has an upper side and a lower side, each having a connection side and a plug-in side.

The shroud is according to the invention by means of at least one

Locking adaptable to different cross sections of ladders.

Preferably, the top of the terminal side and the

Bottom of the connection side U-shaped. Be the top of the connection side and the bottom of the connection side

joined together, results in a tube-like, round opening. In this opening a conductor in the direction of the plug side can be inserted.

The upper side of the connection side and the underside of the connection side each have latching means. By using the at least one latch, the shield plate is universally suitable for a wide variety of applications

Conductor cross sections, for "thin" and "thick" conductors, equally usable. Thin conductors have a conductor cross-section smaller than

2.5mm ² on. In contrast, thick conductors have a conductor cross-section greater than or equal to 2.5 mm ² .

The shield of the conductor can be held either between the top and the bottom of the connection side to the mating side. For this only one possible insulation on the conductor has to be removed. Alternatively, after the insulation has been removed, the shield of the conductor may also be turned over so that it can be removed from the

Connecting side in the direction of the connected conductor, thus away from the plug side points. The first variant is advantageous for the connection of thicker conductors, while the second variant is preferably suitable for the connection of thinner conductors.

Due to the at least one locking is independent of

Conductor cross section always given a secure, detachable contacting the shield. There is therefore a gas-tight contacting, which is possible without a cumbersome assembly of the conductor.

The at least one latching is a first latching nose and a corresponding first latching recess. The shape of the first latch can be round or square. The first latching recess is accordingly shaped to receive the first latching lug, so that it can be securely latched in the latching recess.

In a first variant, the lower side of the connection side of the shielding plate has at least one first latching lug and the upper side of the connection side has at least one first latching recess. In this case, the first latching lug and the first latching recess are arranged on the upper side of the connection side and the underside of the connection side such that they can be locked together.

In a preferred first embodiment, the underside of the connection side has at least one first latching lug. The top of the connection side has at least two first recesses. These at least two first recesses are ideally designed as latching steps. The latching stages allow the connection of different conductor cross sections, as by using the Raststufen the distance between the top of the connection side and the bottom of the connection side is variably adjustable.

In a second, alternative variant, the underside of the

Connection side at least a first latching recess and the top of the connection side at least a first latching lug. In this case, the first latching recess and the first latching lug are arranged on the upper side of the connection side and the underside of the connection side such that they can be locked together.

Preferably, the second variant has an underside of the

Connection side with at least two first recesses, which are designed as latching steps. The latching steps serve, as in the first variant, the variable adaptability to different conductors. The top side of the connection side has at least one first latching lug.

In a further, third variant of the invention, the underside of the connection side has at least one first latching lug. Furthermore, the underside of the connection side, opposite the first latching lug, has at least two first latching recesses. The at least two first recesses are formed as latching steps.

Accordingly, the upper side of the connection side has at least one first latching lug. The first locking lug on the upper side of the connection side is arranged correspondingly for the latching in one of the latching steps of the lower side of the connection side. In addition, the top side of the

Connection side at least two first recesses on. These are formed as latching steps and arranged opposite the first latching lug on the upper side of the connection side and the first latching lug on the underside of the connection side. The first catch of the underside of the

Connection side can be in one of the latching steps of the top of the

Lock connection side. This variant offers the advantage of greatest possible adaptability, since on top of the

Terminal side and the bottom of the terminal side of the shield plate various locking positions are possible, depending on the thickness of the conductor.

Regardless of the selected variant, the at least one first latching lug and the at least one first latching recess are aligned in the direction of the connection side. The positioning of the at least one first latching lug and the at least one first latching recess on the connection side is not only a secure contacting of the shield, but also an early contact. Furthermore, at the same time a strain relief for the conductor is given as it is held over a large area.

In one variant, the shield plate is integrally formed. That is, the area of the top of the mating side and the underside of the mating side is formed from one piece to which corresponding to the respective side, the top of the connection side and the bottom of the connection side is formed. The upper side of the connection side and the underside of the connection side are elastically formed and locked together.

Alternatively, the shroud is formed of two parts. The top side of the connection side and the top side of the connection side are in one piece, the underside of the connection side and the underside of the connection side form the other part.

The shield plate has in the direction of the mating side at the top of the mating side at least a second latching lug and on the underside of the mating side at least one associated second latching recess. Alternatively, the upper side of the plug-in side has at least one second latching recess and the underside of the plug-in side has at least one second latching nose.

Preferably, at least one second latching lug and at least one second latching recess are integrally formed on the underside of the plug-in side and at least one second latching latch and at least one second latching recess in the direction of the plug-in side on the underside of the plug-in side. This provides a stable and secure latching in the area of the complete shielding plate.

The at least one second latching lug and the at least one second latching recess are only in the multi-part design of

Shielding sheet necessary.

The second latching recess and the second latching lug can form identical to the first latching lug and the first latching recess

be executed. Alternatively, the second latching lug and the second latching recess may also have a different shape than the first

Latch and the first recess. Thus, the shape of the first latching lug and the first latching recess may be angular and the shape of the second latching lug and the second latching recess may be elliptical. Alternatively, the shape of the first latch and the first

Locking recess elliptical and the shape of the second latching lug and the second latching recess be angular. In a further alternative, other forms are conceivable. In any form, however, the locking must be guaranteed.

A third locking lug is arranged either on the top or on the bottom or on the top and bottom. It is resilient, elastic and has inwardly on an inserted conductor. It is molded on the connection side and / or on the plug-in side, wherein the resilient arm of the third latching nose points in the direction of the plug side. Advantageously, this creates a flexible fuse. The flexible strain relief is given when a conductor of the

Connection side is pushed in the direction of the plug side in the shield plate. The third detent latches slightly away from the inserted conductor. However, the third detent jammed the inserted conductor in its position when it is loaded on train from the plug side to the connection side. Here, the third latching nose spans and thus secures the inserted conductor. The third latch acts on the principle of Hertzian surface pressure and thus ensures a low resistance.

At the top of the mating side or at the bottom of the mating side or at the top of the mating side and the underside of the mating side a fourth detent is formed. The fourth latch has a resilient arm. The resilient arm points in the direction of the plug side. The fourth locking lug is used to lock the entire connector with a corresponding mating connector.

The present invention solves the problem of presenting a shielding plate with a safe and yet detachable shield connection, wherein the shield connection flexibly to a variety of

Can adapt conductor cross sections. Furthermore, the shield connection is compact, space-saving and robust. By the reversible

Screen connection are also a Erstwirrahtung, a correction and / or repair of a complete connector easily possible.

shroud

Fig. 3 is a perspective view of the preferred top

The figures contain partially simplified, schematic representations. In part, for the same, but possibly not identical

Elements identical reference numerals used. Different views of the same elements could be scaled differently.

FIG. 1 shows a perspective view of a

According to the invention top and a bottom according to the invention, which together form a shroud 3 according to the invention. The upper side has a connection side 4a and a plug side 4.s. The underside has a connection side 5.a and 5.s side plug.

This shroud 3 is receivable in a housing of a connector. The housing is in turn receivable in a connector. However, the housing and the connector are not shown here for the sake of better illustration.

The underside of the mating side 5.s is formed by an area for receiving a mating connector. In this area can be a

Mating connectors are contacted. The plug side is

hollow cuboid formed with two molded half-cylinders.

In each case one of the two half-cylinders is formed on one of the two short sides of the hollow cuboid. At least one contact element projects into this area between the two half-cylinders in a populated state. The underside of the mating side 5.s opposite has the

Shield 3, a bottom of the connection side 5.a on. This is used to connect at least one shielded conductor, wherein the conductor is accommodated in a contact element, which is then inserted from the bottom of the connection side 5.a in the direction of the underside of the mating side 5.s in the shroud 3.

The underside of the connection side 5.a is U-shaped. It has on one side, on a leg of the u of the first underside 5.a, a first locking lug 6. The first locking lug 6 is square. This first locking lug 6 opposite, consequently at the corresponding

opposite leg of the underside of the connection side 5.a, two first recesses 7 are formed. It can also be used any other number of first recesses 7. The first recess 7 is made rectangular in the present embodiment. However, the first recesses 7 may take any shape, which are to be selected only according to the shape of the first locking lugs 6, so that those in the first recesses 7 are receivable and latched.

The two first recesses 7 are arranged as latching steps. For this purpose, it is advantageous if at least two first latching recesses are arranged on the connection side. So the first

Locking recesses latching steps form, they are exactly one above the other, aligned in the direction of the opening of the u. This offers the advantage that a corresponding first locking lug can engage in different positions, depending on the conductor cross-section.

The underside of the connection side 5.a and the bottom of the mating side 5.s are connected by a transition region, which counts partly to the mating side and partly to the connection side. The transition area connects the base of the cuboid of the mating side with the Low-point line of the u the connection side. A broad rectangular area with narrow rectangular areas formed on the long sides of the wide area forms the transition area.

At the narrow rectangular areas are second locking lugs 8 and second recesses 9 on or molded. In the present embodiment, the transition region on one of the two narrow surfaces on two second latching noses 8 and a second latching recess 9. On the opposite surface two second locking lugs 8 and a second recess 9 are arranged. This is an exemplary distribution of the second latching lugs 8 and the second latching recesses 9. There are also other distributions / numbers per narrow side possible.

The top side according to the invention has an upper side of the plug side 4.s, a transition region and an upper side of the connection side 4.a. However, the upper side of the mating side 4.s is formed without the cuboid-shaped region, which is formed on the underside of the mating side 5.s. The transition area is the same as in the

Transition area of the underside of a broad, rectangular area with narrow rectangular areas formed on the long sides of the wide area.

The transition region has a fourth locking lug 1 1. The fourth locking lug 1 1 is provided for locking with a mating connector. It is resiliently formed on the wide surface and points in the direction of the plug side. The fourth latch 1 1 has at least one, in this case two, barbs, which in

Lock mating connector.

On one of the two narrow surfaces are, as a counterpart to

5.s side of the base with which the top side of the 4.s side latched, two second recesses 9 and a second

Latch 8 molded. On the opposite narrow surface also two second recesses 9 and a second locking lug 8 are arranged.

The two narrow surfaces are identical equipped, is only, as already mentioned at the bottom of the mating side 5.s, a possible

Embodiment. For example, it is also possible to arrange only a second detent nose 8 on one narrow surface and a second detent recess 9 on the opposite narrow surface. The narrow surfaces of the top of the mating side 4.s need only be equipped with a corresponding number of second second recesses 9, as the second

5.s underside has second locking lugs 8. This applies analogously to the second latching lugs 8 of the second upper side 4.

The top of the connection side is 4.a like the bottom of the

Connection side 5.a, designed U-shaped. One leg of the u has a first latching nose 6. This is arranged on the leg, that it can engage in one of the first recesses 7 of the underside of the connection side 5.a. On the opposite leg of the u three first recesses 7 are formed. In one of these three first recesses 7, depending on the thickness of the

Conductor cross-section to be recorded, the first latching nose 6 of the bottom of the connection side 5.a snap.

For the shape of the first latching lug 6 and the first latching recess 7 on the upper side of the connection side 4.a the same rule applies as for the first latching recesses 7 and first latching lugs 6, which are arranged on the underside of the connection side 5.a.

The first recesses 7 at the top of the connection side 4.a are analogous to the first recesses 7 of the underside of Connection side 5.a designed as latching steps. They are arranged one above the other. The number of first recesses 7 at the top of the connection side 4.a and the bottom of the

Connection side 5.a, whether identical or different, is arbitrary.

The top 4.a, 4.s, and the bottom 5.a, 5.s are therefore formed so that they are locked together and a

hold the conductor safely. As a result, the shielding of the recorded conductor is advantageously contacted over a large area.

In the figure 2, the top 4.a, 4.s and the bottom 5.a, 5.s of Figure 1 are locked together. In the figure 2, the underside of the mating side are shown 5.s with the cuboid and semi-cylindrical plug side, the transition region and the bottom of the connection side 5.a as opposite U-shaped connection side.

The fourth latching lug 1 1 of the top of the mating side 4.s protrudes in the direction of the mating side and is close to the parallelepiped and semi-cylindrical

Position of the mating side of the underside of the mating side 5.s positioned.

The underside of the mating side 5.s has in this embodiment, in the transition region, three second recesses 9, in which the three second detents 8 of the top of the mating side 4.s engage.

On the connection side of the underside of the connection side 5.a are on a leg of u, towards the viewer, a first latching nose 6 and formed on the opposite leg two first recesses 7. The upper side of the connection side 4.a points towards the viewer three first recesses 7 and opposite a first

Latch 6 on. The first locking lug 6 of the underside of the connection side 5.a engages in the middle of the three first recesses 7 of

Top side of the connection side 4.a. The first locking lug 6 of the top of Connection side 4.a engages opposite in the first recess 7 of the underside of the connection side 5.a, which is arranged closer to the curved portion of the u.

In which first recess 7, the respective locking lug 6 engages depends on the particular conductor to be connected.

FIG. 3 shows a preferred embodiment of the upper side 4.a, 4.s in a perspective view. The top of the mating side 4.s has the fourth locking lug 1 1 with two barbs in the direction of

Plug-in page. In the transition region are three second locking lugs 8 on the one narrow surface and opposite three second

Detent recesses 9 arranged.

At the transition area, the connection side of the top of the connection side closes 4.a on. This is U-shaped. On one of the legs of the u three first recesses 7 are formed. On the opposite leg of the u is a first locking lug 6 is formed.

Particularly preferred is the Anformung a third locking lug 10 at the curved portion of the u, which the two legs of the u

connects with each other. The third locking lug 10 has the advantage of additional contacting a shield of a conductor to be connected and is additionally a strain relief. The zugentlastende effect is given by the orientation of the third latching lug 10, which is integrally formed in the direction of the mating side resiliently on the upper side of the connection side 4.a.
