Description

The invention relates to an electrical socket with the features of the preamble of claim 1.

Such electrical sockets are used in particular in communications and data transmission technology. The sockets each interact with a corresponding connector. The interaction can, for example, create a releasable electrical connection between two data transmission cables. The electrical sockets each have a plug receptacle in which a plurality of contact springs are arranged. A corresponding plug connector can be inserted into the plug receptacle, wherein the contact springs arranged in the plug receptacle can be contacted by associated plug contacts of the plug connector. The contact springs are each electrically connected to a wire connection element. The wires of a data transmission cable can be connected to the wire connection elements. For this purpose, the electrical sockets each have a wire receiving part into which at least one wire of the data transmission cable can be inserted. The wire receiving part can be positioned on the wire connection elements, so that an electrical connection is established between the wire connection elements and the wires of the data transmission cable. The housing of the electrical sockets has a base part, which forms the plug receptacle, and at least one housing wing, which can be moved back and forth between a release position releasing the wire receptacle part and a fixing position defining the wire receptacle part on the wire connection elements. In order to position the wire receiving part on the wire connection elements, the at least one housing wing assumes its release position, so that the wire connection part is given access to the wire connection elements. After the wire connector is Has at least approximately assumed the position on the wire connection elements, the at least one housing wing can be moved into its fixing position, in which it fixes the wire receiving part on the wire connection elements.

Electrical sockets of the type in question are often mounted on a holding device, for example on a support panel. In order to avoid that the electrical sockets unintentionally detach from the holding device, they each have a spring element on the outside of their housing, with the aid of which the electrical sockets can be resiliently clamped to the holding device. Such electrical sockets are for example from the DE 20 2009 013 238 U1 known.

The spring element is often connected in one piece to the housing. Such an embodiment is for example from the US 6,739,898 B1 known. In many cases, the housing of the electrical sockets is made from metal, in particular from a die-cast material. As a result, the housing has high mechanical stability and ensures electrical shielding. However, such housings generally have only a low elasticity. Therefore, configurations are known in which the spring element is designed as a separate component. This allows the spring element to be given a high degree of elasticity despite the hard and brittle design of the housing. Electrical sockets with a spring element designed as a separate component are, for example, from the DE 10 2013 021 296 B3 as well as from the EP 3 276 756 A1 known.

For example, a data transmission cable can be connected to the electrical sockets, which has one or more wires. Each wire has an electrical conductor which is encased in wire insulation. The data transmission cable can have two, four, six or eight wires, for example. In many cases, two wires are twisted together. Alternatively or additionally, two wires can be surrounded by an electrically conductive pair shield. The pair shield can be configured, for example, as an electrically conductive film strip which is wound around a pair of wires. In addition to the at least one wire, the data transmission cable has a cable sheath that surrounds the at least one wire. The cable jacket is made of an insulating material. Frequently, the data transmission cable also has a screen braid arranged between the at least one wire and the cable jacket, which additionally shields the at least one wire. Such data transmission cables are known to the person skilled in the art.

To connect the wires of a data transmission cable to an electrical socket, the ends of the individual wires are positioned in the wire-receiving part of the socket. For this purpose, the wire receiving part has, for example, suitable receiving channels for the wires and clamping elements for clamping the wires. If the wire-receiving part with the wires positioned therein is positioned on the wire-connecting elements, then the wire-connecting elements designed, for example, as cutting / clamping contacts or as piercing contacts each dip into a receiving channel of the wire-receiving part, penetrate the wire insulation and establish electrical contact with the electrical conductor of the respective one Streak here.

To secure the electrical connection between the wires of the data transmission cable and the wire connection contacts, the wire receiving part is fixed to the wire connection elements with the aid of the at least one housing wing. Here, the housing wing exerts a pressing force on the wire-receiving part during the transition from its release position into its fixed position, so that the wire-receiving part and with it the wires arranged therein are pressed against the wire connection elements.

From the US 6,739,898 B1 an electrical socket is known in which two housing wings are mounted on a base part of the housing, which can each be pivoted back and forth between a release position and a fixed position. To secure the position of the housing wings in the fixed position the housing wings can be locked together with the help of locking lugs and locking receptacles. This ensures that the housing wings do not inadvertently move from their fixed position into their release position. However, if the housing wings are locked after the first connection of a data transmission cable to the socket, the locking connection can then only be released again with great effort and, above all, with the risk of damage to the housing wings. Such a release of the latching connection may be necessary, for example, if a test of the electrical connection between the electrical socket and the wires of the data transmission cable produces a negative result.

From the DE 10 2014 008 632 A1 is an electrical socket with the features of the preamble of claim 1 known. In this socket, a spring element is arranged on the outside of the housing, which serves to lock a housing wing of the socket configured as a cover part. The spring element can be moved back and forth between a locking position and an unlocking position. In the locking position, the spring element locks the housing wing, and in the unlocking position, the spring element releases the housing wing. To lock the housing wing, the spring element has locking hooks which cooperate with corresponding locking projections of the housing wing to form a locking connection. To release the latching connection, the spring element has handling projections that a fitter can press together with his fingers.

From the CN 103124017 A Another electrical socket with the features of the preamble of claim 1 is known. The socket has two housing wings and a spring element which locks the two housing wings in a locking position and releases them in an unlocking position.

The object of the present invention is to develop an electrical socket of the type mentioned in such a way that the socket only then can be mounted and fixed on a holding device when the spring element assumes its locking position in which it locks the at least one housing wing in its fixed position.

This object is achieved by an electrical socket with the features of claim 1.

In the case of the socket according to the invention, the spring element arranged on the outside of the housing not only has the function of clamping the electrical socket on a holding device, for example on a support panel, but the spring element has the additional function of the at least one housing wing in its fixed position lock and release the lock if necessary. For this purpose, the spring element can be moved back and forth between a locking position and an unlocking position. In the locking position, the spring element locks the at least one housing wing in its fixed position, and in the unlocking position, the spring element releases the at least one housing wing. If the spring element assumes its unlocking position, the at least one housing wing can be moved from its fixed position into its release position, so that the core receiving part together with the cores arranged therein can then be detached from the housing.

The electrical socket according to the invention thus has the advantage that the wire-receiving part, together with the wires of the data transmission cable arranged therein, can be easily detached from the housing of the socket if required.

According to the invention, the spring element has a front side facing the plug connection side of the housing, on which at least one retaining member is arranged, the at least one retaining member being at a smaller distance from the plug connection side in the locking position of the spring element than in the unlocked position of the spring element. When the electrical plug socket is mounted on a holding device, for example a support panel, the plug connection side of the housing can be passed through an installation opening in the holding device. The smaller distance that the at least one retaining member has in the locking position of the spring element to the connector connection side allows the at least one retaining member to engage behind the mounting opening of the holding device when the electrical socket is mounted on the holding device. In the unlocked position of the spring element, the at least one retaining member is at a greater distance from the connector connection side of the housing. Because of the greater distance, the at least one retaining member cannot reach behind the assembly opening. It is thus ensured that the electrical socket can only be mounted and clamped on the holding device when the spring element assumes its locking position in which it locks the at least one housing wing in its fixed position.

It is advantageous if the spring element is movably mounted on the housing base.

In particular, it can be provided that the spring element is mounted on the housing base so as to be linearly displaceable.

Alternatively, it can be provided that the spring element is movably mounted on a housing wing.

In particular, it can be provided that the spring element is mounted in a linearly displaceable manner on a housing wing.

It is favorable if the spring element forms a positive connection with at least one housing wing in its locking position, provided that the housing wing assumes its fixing position. A reliable locking of the housing wing can be achieved by forming a positive connection between the spring element and at least one housing wing.

In a preferred embodiment of the invention, the spring element engages behind at least one housing wing in its locking position, provided that the latter takes up its fixing position. By reaching behind the housing wing it is ensured in a structurally simple manner that the housing wing cannot carry out any unintentional movement from the fixed position into its release position.

It is particularly advantageous if the housing has a guide element on which the spring element is movably, in particular displaceably mounted. The storage ensures that the spring element does not tilt at the transition between its two positions.

In an advantageous embodiment of the invention, the guide element forms a guide rib and the spring element has a guide recess, the guide rib reaching through the guide recess and the spring element being movable relative to the guide rib. The guide recess can be configured, for example, as an opening in the spring element. The guide rib extends through the guide recess, so that the spring element surrounds the guide rib in the circumferential rib and can be moved back and forth relative to the guide rib between its locking position and its unlocking position.

It is particularly advantageous if the spring element can be locked in the locking position and / or in the unlocking position - in particular on the housing. In particular, an embodiment in which the spring element can be locked both in its locking position and in its unlocking position is advantageous.

It can be provided, for example, that the spring element can be releasably locked to the housing in its locking position and / or in its unlocking position.

It is expedient for the housing to have a guide element, in particular a guide rib, on which the spring element is slidably mounted, with latching elements which interact with one another on the guide element and on the spring element for producing a latching connection between the guide element and the spring element when the spring element is its Assumes the locking position and / or its unlocking position.

In particular, it can be provided that the latching members for producing a latching connection are designed as interacting latching projections and latching recesses.

For example, it can be provided that at least one latching projection is arranged on the spring element, which protrudes into a latching recess of the guide element in the locking position of the spring element and / or in the unlocking position of the spring element.

In an advantageous embodiment of the invention, at least one housing wing has a holding element which, in the locking position of the spring element, can be gripped by a hook-shaped holding section of the spring element when the housing wing assumes its fixing position. If the spring element is moved from its locking position into its unlocking position, the hook-like holding section of the spring element releases the holding element of at least one housing wing, so that it can be moved into its release position unhindered.

It is particularly expedient if the holding element of the housing wing at least partially covers the associated holding section of the spring element when the spring element assumes its locking position and the housing wing assumes its fixing position. In such an embodiment of the invention, the holding section of the spring element engages under the holding element of at least one housing wing. This ensures that the spring element cannot be lifted from this housing wing in its locking position when the housing wing assumes its fixing position. In order to be able to move the spring element in a simple manner from its locking position into its unlocking position, in a preferred embodiment of the invention the spring element has a tool contact element for bearing an auxiliary tool for moving the spring element from the locking position into the unlocking position. As an auxiliary tool, for example, a screwdriver can be used, the tip of which can be positioned on the tool contact element in order to subsequently exert a force on the spring element so that it is moved from the locking position into the unlocking position. In particular, it can be provided that the spring element can be moved from its locking position into its unlocking position with the aid of the auxiliary tool.

The tool contact element can be designed, for example, in the form of an elevation, in particular a tab, or in the form of a recess, for example an opening.

The spring element preferably consists of spring steel, at least in some areas, in particular completely.

In particular, it can be provided that the spring element has a material thickness of 0.3 mm to 0.6 mm.

In an advantageous embodiment of the invention, the spring element consists of plastic, at least in regions, in particular completely.

It is advantageous if the electrical socket has two housing wings, which can preferably be pivoted back and forth about pivot axes aligned parallel to one another between their release position and their fixing position.

The electrical socket preferably has two housing wings which are movably, in particular pivotably, mounted on the housing base.

It is particularly advantageous if at least one housing wing has a pressing element or a plurality of pressing elements for pressing the wire receiving part onto the wire connection elements. The at least one pressing element can be designed, for example, in the form of a housing wing section, in particular a projection, the housing wing section being able to be applied when the housing wing is moved from the release position into the fixing position to a rear side of the core receiving part positioned at the core connection elements and facing away from the wire connection elements.

In the Figures 1 to 11 a first advantageous embodiment of an electrical socket according to the invention is shown schematically, which is denoted overall by reference number 10. A multi-core data transmission cable 12 is connected to the electrical socket 10.

The electrical socket 10 has a housing 14 with a housing base 16, on which a first housing wing 18 is pivotally mounted about a first pivot axis 20, and on which a second housing wing 22 is pivotally mounted about a second pivot axis 24. The two pivot axes 20, 24 are aligned parallel to one another.

The housing base 16 has a plug connection side 25, on which a plug receptacle 26 is arranged. A plurality of contact springs 28, which are positioned next to one another in a row, are arranged in the plug receptacle 26. A complementarily configured plug connector can be inserted into the plug receptacle 26, the contact springs being able to be contacted by associated plug contacts of the plug connector. Such connectors are known per se to the person skilled in the art and therefore do not require any further explanation in the present case.

Figure 1 shows the electrical socket 10 after mounting on a holding device, which is designed as a carrier panel 30 in the illustrated embodiment. The carrier panel 30 has a mounting opening 32 which extends from a front side 34 to a rear side 36 of the carrier panel. Starting from the rear side 36, the electrical socket 10 can be inserted into the mounting opening 32, so that the mounting opening 32 is then engaged behind by a retaining strip 38 formed on the outside on the housing base 16 and by two hook-like retaining members 37, 39 of a spring element 40. By means of the spring element 40, the electrical socket 10 can be clamped on the support panel 30. When inserted into the mounting opening 32, the spring element 40 is slightly elastically deformed. If required, the socket 10 of the assembly opening 32 can also be removed at any time by the spring element 40 is again slightly elastically deformed so that the retaining members 37, 39 release the assembly opening 32.

In the exemplary embodiment shown, the spring element 40 consists at least partially, preferably completely, of spring steel and has a material thickness of approximately 0.3 mm to approximately 0.6 mm. Alternatively, the spring element could at least partially, preferably completely, consist of plastic. The spring element 40 is mounted on an outer side 42 of the housing base 16 facing away from the retaining strip 38 so as to be linearly displaceable, wherein it lies between one in the Figures 2 , 3rd , 4th , 5 and 11 shown unlocking position and one in the Figures 1 , 6 , 7 and 10th shown locking position can be moved back and forth.

The contact springs 28 arranged in the plug receptacle 26 are each electrically connected to a wire connection element 44 via electrical connecting elements known per se and therefore not shown in the drawing. In the exemplary embodiment shown, the wire connection elements 44 are held on a printed circuit board 46, whereby they protrude from a rear side 48 of the printed circuit board facing away from the plug receptacle 26 in the direction facing away from the plug receptacle 26. The wire connection elements 44 are designed as insulation displacement contacts. Alternatively, the wire connection elements could also be configured, for example, as piercing contacts. Such wire connection elements are known per se to the person skilled in the art.

The electrical socket 10 has a wire receiving part 50 with a central through opening 52 through which the exposed wires of the data transmission cable 12 can be passed. On its end face 56 facing the wire connection elements 44, the wire receiving part 50 has a number of receiving channels 58 which corresponds to the number of wires 54, each individual wire 54 being positioned in a receiving channel 58 and by means of those known per se and therefore in the drawing in order to achieve a better overview Clamping elements, not shown, can be clamped in the receiving channel 58.

The two housing wings 18, 22 are between one in Figure 2 shown release position and for example in Figure 4 shown fixing position pivotable back and forth. In their release position, they give the wire receiving part 50 access to the wire connecting elements 44, so that the wire receiving part 50 can be positioned on the wire connecting elements 44. Then the two housing wings 18, 22 can be pivoted from their release position into their fixed position.

The first housing wing 16 has two first pressing elements 62, 64 on its inside 60 facing the second housing wing 22, and the second housing wing 22 has two second pressing elements 68, 70 on its inside 66 facing the first housing wing 18. When the two housing wings 18, 22 transition from their release position into their fixed position, the first and second pressing elements 62, 64, 68, 70 contact the rear side 72 of the wire receiving part 50 facing away from the wire connection elements 44, so that it is separated from the first and second pressing elements 62, 64 , 68, 70 is pressed against the wire connection elements 44. As a result, the wire connection elements 44 penetrate the wire insulation of the individual wires 54 of the data transmission cable 12 and establish an electrical connection with the respective electrical conductor of the wires 54.

In addition to its function of clamping the electrical socket 10 in the mounting opening 32, the spring element 40 has the further function of locking the two housing wings 18, 22 in their fixed position. For this purpose, the spring element 40 is held in a linearly displaceable manner on a guide element of the housing base 16. In the exemplary embodiment shown, the guide element 74 is designed as a guide rib 76 which extends through a central guide recess 78 of the spring element 40, lateral rib projections 80, 82 of the guide rib 76 facing away from one another being gripped by the spring element 40. This is particularly apparent from Figure 3 clear. The guide rib 76 thus covers two opposite edge regions of the spring element 40, which adjoin the guide recess 78 on opposite sides of the guide recess 78.

The guide rib 76 has two first locking elements in the form of two groove-like first locking recesses 84, 85 and two second locking elements in the form of two groove-like second locking recesses 86, 87. The spring element 40 has two knob-like locking projections 8o, 90, which each dip into one of the first locking recesses 84, 85 in the unlocking position of the spring element 40 and which each dip into one of the second locking recesses 86, 87 in the locking position of the spring element 40. This allows the spring element 40 to be locked on the housing base 16 both in the unlocked position and in the locked position.

The spring element 40 forms a latching tongue 92 which, on its front side 93 facing the plug connection side 25, bears the retaining members 37, 39 already mentioned, with which the spring element 40 engages through the mounting opening 32 when the electrical socket 10 is mounted on the carrier panel 30. This will be out Figure 1 clear. Averted from the latching tongue 92, the spring element 40 has two hook-like holding sections 94, 96 which are arranged on outer sides 98 and 100 of the spring element 40 which face away from one another.

The hook-like holding section 94 of the spring element 40 interacts with a first holding element 102 of the first housing wing 18, which in the exemplary embodiment shown is designed as a first holding rib 104, the rear end region 106 of which, facing away from the first pivot axis 20, is encompassed by the hook-like holding section 94, the rear end region 106 forms a positive connection with the holding section 94 when the spring element 40 assumes its locking position.

The hook-like holding section 96 of the spring element 40 interacts with a second holding element 108 of the second housing wing 22, which in the exemplary embodiment shown is designed as a second holding rib 110, whose rear end region 112 facing away from the second pivot axis 24 is encompassed by the holding section 96, the rear end region 112 forming a positive connection with the holding section 96 when the spring element 40 assumes its locking position.

The two holding ribs 104, 110 each have a holding projection 114 or 116 on their outer sides facing away from one another, which is undercut by the respectively assigned holding section 94 or 96 when the spring element 40 assumes its locking position. This is particularly apparent from Figure 10 clear.

On its rear side 118 facing away from the latching tongue 92, the spring element 40 has a tool contact member 120 in the area between the two holding sections 94, 96, which in the exemplary embodiment shown is designed as a tab 122 bent upward in the direction facing away from the housing base 16. At a distance from the tab 122, the guide recess 78 of the spring element 40 forms a stop surface 124 which, in the locking position of the spring element 40, comes to rest on a rear side 126 of the guide rib 76 facing the tab 122. This ensures that the tab 122 is at a distance from the guide rib 76 in the locking position of the spring element 40.

An auxiliary tool 128 can be positioned with a tool tip 130 on the side of the tab 122 facing the guide rib 76 in order to exert a pushing force on the spring element 40, under the effect of which the spring element can be displaced from its locking position into its unlocking position. This is particularly evident from the Figures 10 and 11 clear.

To establish an electrical connection between the wires 54 of the data transmission cable 12 and the contact springs 28 of the electrical socket 10, the wires 54 can first be exposed and passed through the central through opening 52 of the wire receiving part 50 become. The exposed wires 54 can then each be clamped into a receiving channel 58 of the wire receiving part 50, and then the wire receiving part 50 can be positioned on the wire connection elements 44 of the electrical socket 10. Here, the two housing wings 18, 22 take their in Figure 2 shown release position.

In a further assembly step, the two housing wings 18, 22 can be pivoted from their release position into their fixed position, the wire receiving part 50 being pressed against the wire connection elements 44 under the action of the pressing force exerted by the pressing elements 62, 64, 68, 70, so that the wire connection elements 44 configured as cutting / clamping contacts each penetrate wire insulation and form an electrical contact with an electrical conductor of a wire 54.

When the housing wings 18, 22 are pivoted out of their release position into their fixed position, the spring element 40 first assumes its unlocking position, in which the locking projections 89, 90 dip into the first locking recesses 84, 85.

After the housing wings 18, 22 have been pivoted into their fixed position, the spring element 40 can be moved into its locking position, in which the latching projections 89, 90 dip into the second latching recesses 86, 87. In this locking position, the hook-like holding sections 94, 96 each encompass an end region 106, 112 of the holding elements 102, 108 of the two housing wings 18, 22 and form a positive connection with these end regions 106, 112. The two housing wings 18, 22 are thereby reliably locked in their fixing position, so that it is ensured that the housing wings 18, 22 cannot inadvertently move from their locking position into their release position and the wire receiving part 50 can thereby detach from the wire connection elements 44.

In the locking position of the spring element 40, the retaining members 37, 39 take a smaller distance from the connector connection side 25 of the housing base 16 than in the unlocked position of the spring element 40. The smaller distance allows the retaining members 37, 39 to engage behind the mounting opening 32 when the socket 10 is mounted on the carrier panel 30. In the unlocked position of the spring element 40, the retaining members 37, 39 are so far away from the plug connection side 25 of the housing base 16 that they cannot reach behind the mounting opening 32 when the socket 10 is mounted on the carrier panel 30. It is thus ensured that the socket 10 can only be mounted and clamped on the carrier panel 30 when the spring element 40 assumes its locking position in which it locks the two housing wings 18, 22 in their fixed position.

If the electrical connection between the wires 54 of the data transmission cable 12 and the wire connection elements 44 of the electrical socket 10 is to be disconnected, it is only necessary to remove the socket 10 from the mounting opening 32 and then the spring element 40, for example with the aid of the auxiliary tool 128, from it To move the locking position back into its unlocking position. In the unlocked position, the holding sections 94, 96 of the spring element 40 completely release the associated holding elements 102 and 108 of the two housing wings 18, 22, so that the housing wings 18, 22 can be easily pivoted back out of their fixed position into their release position and then that Wire receiving part 50 can be removed from the wire connection elements 44.

In the Figures 12 and 13 a second advantageous embodiment of an electrical socket according to the invention is shown schematically, which is denoted overall by reference numeral 210. The electrical socket 210 is largely identical in design to that described above with reference to FIG Figures 1 to 11 described electrical socket 10. For identical components are therefore in the Figures 12 and 13 the same reference numerals as in the Figures 1 to 11 and regarding these components To avoid repetition, reference is made to the explanations above.

The electrical socket 210 has a housing base 216 and a first housing wing 218 and a second housing wing 222. The two housing wings 218, 222 are pivotally mounted on the housing base 216. In contrast to the housing base 16 explained above, the in the Figures 12 and 13 shown housing base 216 no guide rib. Instead, a guide rib 276 is arranged on the second housing wing 222, which is configured identically to that above with reference to FIG Figures 1 to 11 explained guide rib 76.

The guide rib 276 serves for the displaceable mounting of a spring element 240, which is configured largely identically to that with reference to FIG Figures 1 to 11 explained spring element 40. The spring element 240 has a guide recess 278, which is penetrated by the guide rib 276. In contrast to the spring element 40 explained above, the spring element 240 has only a single hook-like holding section 294 which faces the first housing wing 218 and interacts positively with a holding element 302 of the first housing wing 218 by the holding section 294 engaging around a rear end region 306 of the holding element 302 when the spring element 240 assumes its locking position. A further hook-like holding section is not required for the spring element 240, since this is held on the guide rib 276 of the second housing wing 222.

The wires 54 of the data transmission cable 12 can be connected in a simple manner to the contact springs 28 of the electrical socket 210 and, if necessary, this connection can be separated in a simple manner. To connect the wires 54, it is only necessary to pivot the two housing wings 218, 222 into their release position, so that the wire receiving part 50 of the electrical socket 210 together with the wires 54 of the data transmission cable 12 arranged therein on the wire connection elements 44 the electrical socket 210 can be positioned. The two housing wings 218, 222 can then be pivoted into their fixed position, the wire receiving part 50 being pressed against the wire connection elements 44 of the electrical socket 210. The two housing wings 218, 222 can then be locked in their fixed position by means of the spring element 240. For this purpose, the spring element 240 is shifted from its unlocking position into its locking position, in which it engages with the holding section 294 around the holding element 302 of the first housing wing 218 to form a positive fit. If the data transmission cable 12 is to be separated again from the electrical socket 210, it is only necessary to move the spring element 240 into its unlocked position, in which the holding section 294 releases the holding element 302, so that the two housing wings 218, 222 pivot into their release position can be.
