Description

[0001] The invention relates to a plug-in housing for at least partially receiving a housing plug-in component and an electrical plug connection arrangement for connecting a male contact element and a female contact element.

[0002] It is known from practical experience that, for electrical connector assemblies, finger contact safety in accordance with DIN 60 664-1 is required to protect against accidents. To verify whether finger contact safety is ensured in an electrical connector assembly with housing components containing male contact elements, a standardized test finger is pressed with a defined force against or into an opening of a housing component of the electrical connector assembly, and it is checked that no current-carrying component, such as the male contact elements, comes into contact with the test finger.

[0003] To ensure finger safety even when the electrical connector assembly is not mated, it is necessary to cover any exposed, live male contacts on the housing components. This can be achieved, for example, by snapping or gluing a cap made of electrically insulating material onto a male contact element of the electrical connector assembly, such as a contact pin. However, this type of covering of the male contacts can be cumbersome and time-consuming.

[0004] Furthermore, connecting the housing components of the electrical connector assembly can be difficult because the male contact element is no longer freely accessible due to the cap placed on it, making it impossible to establish an electrically conductive connection between the male and female contact elements. To nevertheless enable the connection of the male and female contact elements, it may be necessary to open or remove the cap placed on the male contact element.

[0005] In this context, an electrical connector with a connector housing made of an insulating material is known from DE 20 2008 002 091 U1. A conductor connection element for connecting an external conductor is arranged in the connector housing, as well as a contact element electrically connected to the conductor connection element. The connector housing includes a conductor entry opening for inserting a conductor to be connected and at least one actuating opening for actuating the at least one conductor connection element. Furthermore, an electrical terminal block with two connectors and an electrical terminal block with one connector and a base body are known from DE 20 2008 002 091 U1. The base body comprises a housing and at least one metallic mating contact element arranged therein for electrically contacting the at least one contact element of the connector.

[0006] It is an object of the invention to provide measures by which, in the case of a plug-in housing and / or an electrical plug-in connection arrangement, touch safety for a person in a non-plug-in state of the plug-in connection device is ensured in a simple and cost-effective manner.

[0007] According to the invention, the problem is solved by a plug-in housing for at least partially receiving a housing plug-in component with the features of claim 1 and an electrical plug connection arrangement for connecting a male contact element and a female contact element with the features of claim 7. Advantageous embodiments of the invention are specified in the dependent claims.

[0008] According to the invention, a plug-in housing is provided for at least partially receiving a housing plug-in component, wherein a female contact element is arranged in the housing plug-in component, comprising a base body which has a recess and a through-opening arranged in a bottom wall of the recess, wherein the recess is chamber-shaped with a substantially rectangular cross-section, wherein the through-opening extends through the base body, wherein a section of a male contact element can be inserted into the recess through the through-opening, and a U-shaped contact element which is arranged centrally in the recess adjacent to the through-opening and projects into the recess, such that the section of the male contact element can be applied to a side of the U-shaped contact element facing the through-opening.

[0009] In particular, the term "male contact element" can refer to a protruding, freely accessible, electrically conductive element. In particular, the term "female contact element" can refer to an electrically conductive element that may have a receptacle for receiving a male contact element.

[0010] The plug-in housing according to the invention is therefore based on the concept of permanently covering an outwardly facing end face of an exposed male contact element by means of a contact element arranged, in particular, in line with the through-opening of the plug-in housing. This ensures finger contact protection or, more generally, contact protection of the plug-in housing, since the end face of the male contact element cannot be freely accessible when the plug-in housing and the housing insert are not connected, thus preventing unintentional contact with the male contact element at this end face. The freely accessible cross-section of the recess can be reduced by providing the contact element in a mating face of the plug-in housing, thereby reducing the risks of accidentally reaching past the contact element and of laterally touching the male contact element.

[0011] In particular, the touch safety of the connector housing can be achieved very simply and cost-effectively, since no additional cap made of electrically insulating material is required to cover the male contact element. Furthermore, the handling of the connector housing and the electrical connector assembly can be simplified in use, as the connector housing and the housing insert can be plugged into each other without any further steps.

[0012] In particular, the female contact element can be connected to a first conductor arrangement and / or the male contact element can be connected to a second conductor arrangement, so that a corresponding electrical connection of both conductor arrangements via the male and female contact elements can be made possible. Specifically, the female contact element can be part of the first conductor arrangement and / or the male contact element can be part of the second conductor arrangement.

[0013] In one embodiment, the contact element can be essentially U-shaped, with leg ends of the contact element being connected to the bottom wall of the recess adjacent to an edge section of the opening. This allows the male contact element to be held particularly securely in the recess, as the contact element can be surrounded by several end faces. Furthermore, the touch safety of the connector housing can be further increased, as additional exposed end faces of the male contact element can be covered by the contact element.

[0014] In a further embodiment, the legs of the contact element can be at least partially, for example along a longitudinal extension of the legs, partially or completely connected to opposite side walls of the recess. Therefore, the contact element can be particularly stable and firmly connected to the base body, thus preventing unintentional bending or breakage of the contact element. Furthermore, the freely accessible cross-section of the recess can be reduced in the longitudinal direction of the contact element, thus providing a particularly high level of touch resistance for the plug housing.

[0015] According to the invention, the recess is chamber-shaped with a substantially rectangular cross-section, with the U-shaped contact element being arranged centrally within the recess. This measure allows the freely accessible cross-section of the recess to be uniformly reduced, so that the touch safety of the plug housing can be equally good across the entire cross-section of the recess.

[0016] In a further embodiment, the plug-in housing can also have a rib-shaped reinforcing element that can be arranged in the recess and extend transversely, in particular perpendicularly, to the mating element, wherein the reinforcing element can connect the mating element to a side wall of the recess. In particular, the reinforcing element can be designed as a rib or in a rib-like form. This allows the mating element to be supported on the side wall of the recess, thus improving the positional stability of the mating element in the recess of the plug-in housing. Furthermore, the exposed cross-section of the recess between the mating element and the side wall can be further reduced, thus additionally improving the touch safety of the plug-in housing.

[0017] In particular, the reinforcing element can be connected to the base wall. Specifically, a reinforcing element can be provided on each side of the system element.

[0018] In a further embodiment, the base body, the contact element, and / or the reinforcement element can be formed in one piece and / or comprise or be formed from electrically insulating material, in particular plastic. This allows the plug housing to be manufactured particularly simply and therefore cost-effectively. Manufacturing the base body, the contact element, and / or the reinforcement element from electrically insulating material can prevent an electrically conductive connection of the male contact element via adjacent components.

[0019] In particular, at least one further section of the male contact element can be positively engaged in the through-hole and / or the section of the contact element can be positively engaged on the inside of the mounting element, so that unintentional release of the male contact element from the or the plug housing can be prevented.

[0020] In a further embodiment, the male contact element can have a contact blade or be designed as a contact blade, and the through-hole can have an elongated cross-section. The terms "contact blade" or "blade contact" can each denote an end section of an electrical conductor, which can be particularly flat or rectangular, for example, similar to the shape of a knife or knife end. This design of the male contact element, especially compared to a design with a contact pin, can create an enlarged contact area for electrical contact. Furthermore, the large friction surface of the contact blade can make it more difficult to detach.

[0021] Alternatively, the male contact element can have a contact pin or be designed as a contact pin, and the through-hole of the connector housing can have a corresponding shape that may be adapted to the cross-sectional shape of the contact pin. The term "contact pin" can, in particular, refer to an end section of an electrical conductor, which may be cylindrical in shape.

[0022] The invention further relates to an electrical plug-in connection arrangement for connecting a male contact element and a female contact element, comprising a housing plug-in component having a recess and a through-opening in a bottom wall of the recess, the female contact element arranged in the recess, a plug-in housing as described above, and the male contact element, wherein a section of the male contact element is inserted through a through-opening of the plug-in housing into a recess of the plug-in housing and rests against a side of a U-shaped contact element of the plug-in housing facing the through-opening, and wherein the housing plug-in component can be inserted into the recess of the plug-in housing, such thatthat the female contact element at least partially receives the U-shaped contact element and the section of the male contact element arranged in the recess when the housing insert component is inserted, and touches opposite sides of the section of the male contact element on the inside.

[0023] When the plug-in housing and the housing insert component are inserted, the female contact element can partially or completely slide past the mating element and partially or completely past the section of the male contact element, so that the male and female contact elements can be electrically connected via the lateral end faces of the male contact element. This can enable good electrical contact between the male and female contact elements while simultaneously ensuring touch safety and ease of handling of the plug-in assembly.

[0024] The embodiments of the electrical connector arrangement described below also apply to the connector housing.

[0025] In particular, an outer surface of the bottom wall of the recess of the housing plug-in component can be supported against the bottom wall of the recess of the plug-in housing when plugged in.

[0026] In one embodiment, the female contact element can have two or more opposing, and in particular pre-tensioned, spring arms into which the section of the male contact element can be forcefully inserted when the housing insert component is in the inserted state. In particular, the female contact element can be designed as a contact tulip. The term "contact tulip" can, in particular, refer to a multi-segmented female contact element. This allows the female contact element to be designed with a particularly simple structure, and unintentional release of the male contact element from the female contact element can be prevented due to the spring arms pressing against the male contact element.

[0027] In particular, the number of opposing spring arms can be the same, so that the force that can be applied to the male contact element is both increased and evenly distributed across freely accessible, lateral end faces of the male contact element. This can enable a particularly secure arrangement of the male contact element within the female contact element, while simultaneously minimizing material stress on the male contact element when inserted.

[0028] In particular, at least one spring arm, or several, and especially all, of the opposing spring arms, can be multi-segmented, especially with an equal number of elongated finger sections or elongated tongue sections. As explained above, this can enable a particularly secure arrangement of the male contact element within the female contact element, while simultaneously minimizing the material stress on the male contact element in its inserted state.

[0029] In a further embodiment, the ends of the spring arms can be spaced apart, in particular slightly, from sections of a bottom wall of the recess which extend transversely, in particular perpendicularly, to a longitudinal extent of the recess, so that the female contact element can be electrically isolated from the housing insertion component.

[0030] In particular, alternatively, the ends of the spring arms can touch, abut, or be supported against sections of the recess's bottom wall that extend transversely, especially perpendicularly, to the recess's longitudinal extent. This ensures that the female contact element is securely positioned within the recess and prevents it from slipping when the male and female contact elements are inserted into each other.

[0031] In a further embodiment, the plug connection arrangement can also have an overspring that can forcefully surround the spring arms of the female contact element. This allows the force of the spring arms on the male contact element to be increased and kept constant over time, thus ensuring consistently good electrical contact between the female and male contact elements.

[0032] In the event that the legs of the attachment element can be connected to opposite side walls of the recess of the plug-in housing, the associated housing plug-in component can have two lateral openings in a bottom wall and / or adjacent side walls of the recess of the housing plug-in component adjacent to the through-opening of the housing plug-in component, which can be connected to the through-opening and the recess of the housing plug-in component, so that the attachment element can be plugged into the recess and the lateral openings of the housing plug-in component and the positional stability of the plug-in connection arrangement in the plug-in state can be particularly high.

[0033] If the plug-in housing can have a reinforcing element, the bottom wall of the recess can have a corresponding further lateral opening extending transversely, in particular perpendicularly, to the through-opening of the housing plug-in component, so that the housing plug-in component can be securely held in the plug-in housing. Finger sections of a spring arm of the female contact element can be arranged spaced apart from the further lateral opening to allow the reinforcing element to be received in the further lateral opening.

[0034] In particular, the housing insert component can be manufactured in one piece and / or have or be made of electrically insulating material. This allows the housing insert component to be manufactured cost-effectively and easily, and can prevent unintentional electrical contact via the housing insert component.

[0035] In particular, the plug-in housing can have a plurality of sections, each with a recess and a through-opening as described above, into which a male contact element as described above can be inserted. In particular, the plug-in housing component can have a plurality of sections, each with a recess and a through-opening as described above, in which a female contact element as described above can be arranged. In particular, the female contact elements can be connected to or are connected to the first conductor arrangement, and the male contact elements can be connected to or are connected to the second conductor arrangement, so that electrical contact between both conductor arrangements can be achieved quickly and easily via multiple contact points using the plug-in connection arrangement.

[0037] For the sake of clarity, only one element of identical elements is marked with a reference symbol in each figure.

[0038] An electrical connector arrangement 10 according to a first embodiment has a Figures 1a - 1h shown plug housing 12 and one in Figures 2a - 2g shown housing plug-in component 14, which can be partially received in the plug-in housing 12 in a plugged-in state of the housing plug-in component 14.

[0039] The plug-in housing 12 has a base body 16 with six identical recesses 18. Each recess 18 of the plug-in housing 12 is chamber-shaped with a rectangular cross-section and is formed in the base body 16 from a common top surface. Six through-openings 20 of the body 16 of the plug-in housing 12 extend through the body 16, and each through-opening 20 opens into a bottom wall 22 of a recess 18. The through-opening 20 tapers in a stepped manner towards the recess 18 and has an elongated, rectangular cross-section. One depth direction of the through-opening 20 corresponds to one depth direction of the recess 18.A section 24 of a boundary wall 26 of the passage opening 20 extends perpendicular to the depth direction of the passage opening 20 and forms a full-length contact surface for a male contact element 28 designed as a contact knife of the electrical plug connection arrangement 10.

[0040] Each U-shaped mounting element 30 of the plug-in housing 12 is arranged adjacent to and in line with a through-opening 20 in a recess 18 and projects into the recess 18 from the bottom wall 22. The mounting element 30 has a substantially U-shaped body with a first and second leg 32, 34 and a connecting section 36 extending perpendicular to the first and second leg 32, 34. A leg end 38, 40 of the first and second leg 32, 34 is each connected to a section of the bottom wall 22 of the recess adjacent to an edge section 42, 44 of an edge 46 of the through-opening 20. The mounting element 30 is arranged centrally in the recess 18 and spaced apart from four side walls 48a-d of the recess 18.

[0041] The plug-in housing 12 and the six system elements 30 are made of plastic in one piece.

[0042] Each contact blade 28 has a flat, one-piece body of constant thickness, which tapers in a step-like manner towards one end. When the contact blade 28 is inserted into the plug housing 12, it is positively engaged in the through-opening 20, and a tapered section 50 of the contact blade 28 rests positively against an inner surface of the contact element 30 facing the through-opening 20 by means of three end faces.

[0043] The housing insert component 14 has a cuboid base body 52 on which six identically shaped, nose-like projections 54 are arranged. Each of the six substantially parallel and identically shaped recesses 54 extends through the base body 52 into a projection 54. Each of the six through-openings 58 of the housing insert component 14 is arranged centrally in a fully enclosed end face 60 of the projection 54, which is formed by an outer surface of a bottom wall 59 of the recess 54. A female contact element 61, each having a contact tulip, is arranged in the recess 56 in the region of the nose-like projection 54 adjacent to the through-opening 58. The contact tulip has two opposing spring arms 62, 64, each of which is formed with three segments, i.e., each has three elongated finger sections.The female contact element 61 has, in addition to the contact tulip, a flat section which is connected to the contact tulip and spaced along a longitudinal direction of the female contact element 61 from the bottom wall 59 of the recess 56. The contact tulip and the flat section are formed as a one-piece, folded stamped component which has two folded sections that are mirror images of each other with respect to a central plane of the female contact element 61. The central plane contains the longitudinal direction of the female contact element and runs perpendicular to the drawing plane. Figure 3cThe two folded sections are positively connected to each other in the area of ​​the flat section of the female contact element 61. The ends of the two opposing spring arms 62, 64 of the contact tulip of the female contact element 61 are spaced apart with a small amount of clearance from sections 66, 67 of the bottom wall 59 of the recess 56, which extend perpendicular to the depth direction of the recess 56. A superspring 70 is clipped over the spring arms 62, 64 of the contact tulip of the female contact element 61 and receives the spring arms 62, 64 in their clipped-together state in a force-fit manner. For this purpose, the superspring 70 is also designed as a one-piece, folded stamped component, which has two folded sections that are mirror images of each other with respect to their central plane. The central plane runs perpendicular to the drawing plane. Figure 3cand contains a longitudinal direction of the overspring 70 that corresponds to the longitudinal direction of the female contact element 61 and the depth direction of the recess 56e. In its clipped state, the overspring 70 has a cuboid section to which two spring arms 71, 72, each with three segments, are attached. The spring arms 62, 64 of the female contact element 61 are, finger-wise, covered by the spring arms 71 and 72 of the overspring 70, respectively, in the clipped state of the overspring 70 over the female contact element 61, and project slightly finger-wise from the spring arms 71, 72 of the overspring 70.

[0044] Six units, each consisting of a female contact element 61 and an overspring 70, are arranged alternately rotated by 180 degrees relative to each other.

[0045] The one-piece housing insert component 14 is made of plastic.

[0046] In the inserted state of the housing insert component 14, each nose-shaped extension 54 of the housing insert component 14 is received in the corresponding recess 18 of the plug-in housing 12, and the base body 52 rests circumferentially on end sections of the boundary walls 48a-48d of the recess 18. The end face 60 of the extension 54 rests against the bottom wall 22 of the recess 18 at a distance from the edge 46 of the through-opening 20. The legs 32, 34 and the connecting section 36 of the mounting element 30 are received in the nose-shaped extension 54. The spring arms 62, 64 of the contact tulip of the female contact element 61 laterally encompass the contact element 30 and the end face of the section 50 of the contact knife 28 adjacent to the contact element 30 and lie against opposite and freely accessible side surfaces 73, 74 of the section 50 of the contact knife 28.This establishes an electrical connection between the contact blade 28 and the contact tulip of the female contact element 61, such that a first conductor arrangement 76, which is connected to the female contact elements 61 by means of a plug connection, and a second conductor arrangement 78, which is connected to the contact blades 28 by means of a clamp connection, are electrically contacted via 36 electrical contact points. Fig. 3c The first and second ladder arrangements 78, 80 are indicated by dashed lines.

[0047] One in Figures 4a - 6c The electrical connector arrangement 10 shown according to a second embodiment is similar to the electrical connector arrangement 10 according to the first embodiment.

[0048] However, legs 32, 34 of a mounting element 30 of a plug-in housing 12 are completely connected along their longitudinal extent to opposite side walls 48b, 48d of the recess 18. The longitudinal extent of the legs 32, 34 corresponds to the depth direction of the recess 18. In other words, the legs 32, 34, viewed along the longitudinal direction of the mounting element 30, are wider than the legs 32, 34 of the recess 18. Figures 1a, 1b and 1c The depicted plant element 30 is formed.

[0049] In addition to the feature described in the above, a housing plug-in component 14 of the electrical connector assembly 10 has a housing plug-in component 14. Figs. 2a to 3cThe illustrated housing insert component 14 has two lateral openings 80, 82 in opposing side walls 79a, c of side walls 79a-d and an end face 60 of a nose-shaped extension 54, each having a substantially rectangular cross-section and connecting the recess 56 and the through-opening 58 outwards in the longitudinal direction of the through-opening 58. The side walls 79a, c of the extension 54 are formed by opposing side walls of the recess 56, which, viewed in the longitudinal direction of the through-opening 58, delimit the recess 56. The end face 60 corresponds to an outer surface of a bottom wall 59 of the recess 56.

[0050] In the case of the housing insert component 14 being inserted into the plug housing 12, the extension 54 is received in the recess 18 and the mounting element 30 extends through the lateral openings 80, 82 and the recess 56.

[0051] One in Figures 7a - 9c The electrical connector arrangement 10 shown according to a third embodiment is similar to the connector arrangement according to the second embodiment, which is described in Figures 4a to 6c shown. Recesses 18 of a plug-in housing 12 are in Figure 9c Shown as dashed lines.

[0052] However, the plug-in housing 12 additionally features two rib-shaped reinforcing elements 84, 86, which are arranged in the recess 18 and extend from one side wall 48a or 48b of two opposing side walls 48a, 48c of the recess 18 to one side of a mounting element 30, and are partially connected to the mounting element 30 and the corresponding side wall 48a, 48c. The reinforcing elements 84, 86 are arranged centrally in the recess 18 along a longitudinal extension of the mounting element 30 and are connected to the bottom wall 22 of the recess 18. The plug-in housing 12, the mounting elements 30, and the reinforcing elements 84, 86 are formed in one piece from plastic.

[0053] A housing plug-in component 14 of the electrical connector assembly 10 additionally has two lateral openings 88, 90 in opposite side walls 79b, d and an end face 60 of each extension 54. These openings have a substantially rectangular cross-section and extend perpendicular to the through-opening 58 of the nose-shaped extension 64. The side walls 79b, d are formed by corresponding side walls of the recess 56. The lateral openings 88, 90 are arranged centrally in the nose-shaped extension 54 when viewed along a longitudinal extension of the through-opening 58. Spring arms 62, 64 of a female contact element 61 are each formed with two segments, i.e., with two elongated finger sections each. The two finger sections of each spring arm 62, 64 are arranged on opposite sides of the lateral opening 90, 88 and spaced apart from the lateral opening 90, 88.Spring arms 71, 72 of an overspring 70 are also each designed as two-part sections, and two finger sections of each spring arm 71, 72 of the overspring 70 are arranged spaced apart from the corresponding lateral openings 88, 90. The relative arrangement of the spring arms 62, 64 of the female contact element 61 and the spring arms 71, 72 of the overspring 70 is similar to that shown in [reference]. Figures 3a-3c and 6a - 6c The relative arrangements of the spring arms 62, 64 of the female contact element 61 and the spring arms 71, 72 of the overspring 70 are shown.

[0054] When the housing insert component 14 is plugged into the plug housing 12, the system element 30 is, as already described with reference to Figures 4a - 6cAs described, the first and second reinforcing elements 84 and 86 are received in the recess 56 and the lateral openings 80 and 82, respectively, and the first and second reinforcing elements 84 and 86 are received in the lateral opening 90 and the recess 56 and in the lateral opening 88 and the recess 56, respectively. This results in the electrically conductive contact of a first and second conductor arrangement 76 and 78 with each other via 24 contact points.
