Technical Field

The invention relates to a secondary fixing device for locking a plug-in electrical connector comprising a plug-in electrical connector and a mating electrical plug-in connector according to the preamble of claim 1.

The invention also relates to a plug-in electrical connector for connection to a mating electrical plug-in connector, which has a housing and an interference insertion means, as described in the preamble of claim 5.

In addition, the invention relates to a plug-in electrical connector.

Background

When manufacturing a cable, the conductors of the cable are usually connected to a plug-in connector in order to be able to subsequently establish an electrical connection with other cables or conductors having a corresponding plug-in connector or a mating plug-in connector. The plug-in connector or mating plug-in connector may be a plug, a built-in plug, a socket, a coupling or an adapter. The term "plug-in connector" or "mating plug-in connector" used within the scope of the present invention denotes all variants.

In particular, stringent requirements with regard to the robustness and safety of the plug-in connection are imposed on plug-in connectors for the automotive industry or for vehicles. Thus, the plug connector must sometimes be subjected to high loads, for example mechanical loads, and remain closed in a defined manner, so that the electrical connection cannot be unintentionally broken, for example during operation of the vehicle. In particular in the case of autonomous operation of the vehicle and driver assistance systems, the guarantee of safety is of great importance.

It is common practice to use so-called secondary fixing means in order to fix the plugged-in state of a plug-in electrical connector, which comprises a plug-in connector and a mating plug-in connector. Known secondary securing devices are usually movable between a preliminary latching position and a locking position, wherein a securing element of the secondary securing device mechanically secures the plug connector in the locking position.

It is also known from practice that, in addition to the fixing elements, the secondary fixing means have so-called blocking insertion means which, in an initial position, block the insertion of the mating plug-in connector into the plug-in connector in a form-fitting manner and, in a release position, release a displacement path for inserting the plug-in connectors together. In this way, unintentional or possibly resulting incomplete insertion of the mating plug-in connector into the plug-in connector can be prevented.

In this case, the known secondary fixing means are designed such that they can be pushed in by a user, for example the assembler of the plug-in connector, along a linear movement orthogonal to the insertion direction of the mating plug-in connector in the plug-in connector. As a result of this linear displacement, the securing element is moved into the locking position and latched in the desired latching position. Due to the linear movement, the blocking insertion device is also moved out of the displacement path of the mating plug-in connector.

In practice, however, the use of such secondary fixing means is limited to plug-in connectors or plug-in connectors whose interface provides sufficient space to hinder inward displacement of the plug-in means into the plug-in connector. This is not in line with the increasing demands for designing plug connectors in a compact and space-saving manner.

Another problem also arises when the displacement path in the interior space of the plug-in connector or in the interface of the plug-in connector, which obstructs the insertion device, is prevented in some other way. In order to ensure a high degree of process reliability of the plug-in connection, it is sometimes necessary to ensure that the contact elements do not undergo mechanical damage (for example deformation or fracture) even when the mating plug-in connector and the plug-in connector are joined together at an angle. In order to prevent such damage and to ensure so-called "coriolis (Koshiri) safety", at least one contact element, in particular the outer conductor, is usually formed as a coriolis ring or is surrounded by a coriolis ring. The coriolis ring in the interface of the plug-in connector naturally protrudes relatively far forward, with the result that a displacement path for obstructing the insertion device may be prevented.

Disclosure of Invention

The object of the invention is to provide a secondary fixing device for locking a plug-in electrical connector, which can be used in a variable manner for a large number of types of plug-in connectors, in particular for compact plug-in electrical connectors and plug-in connectors with a coriolis ring.

This object is achieved by the features of claim 1.

It is a further object of the invention to provide a plug-in electrical connector and a plug-in electrical connector with improved interference insertion means which can also be used in particular in combination with a coriolis ring.

This object is achieved by a plug-in electrical connector according to claim 5 and by a plug-in electrical connector according to claim 14.

The dependent claims relate to advantageous embodiments and variants of the invention.

The secondary fixing device according to the invention for locking a plug-in electrical connector, which comprises a plug-in electrical connector and a mating plug-in electrical connector, has a fixing element and an interference insertion device. The securing element can be moved by a closing movement from a preliminary latching position into a locking position in which it mechanically secures the plug connector.

In this case, the fixing element can preferably be designed to mechanically fix the housing of the plug-in connector to the outer conductor of the plug-in connector. For this purpose, the fastening element can have, for example, at least one latching hook or at least one latching lug, which latches to the housing of the plug-in connector. In addition or as an alternative, the fixing element can have one or more partial annular projections, plates, fingers or other projections which can be inserted into corresponding slots or grooves of the housing of the plug-in connector. The manner of mechanical fixing by means of the fixing element is, however, not of importance in principle, but the above-described variant is a preferred embodiment of the invention.

The fixing element or the secondary fixing means can be fastened in a captive manner to the plug-in electrical connector in the preliminary latching position, for example by one or more latching lugs being latched in the housing of the plug-in connector. Thus, the secondary fixing means can be fixed, in particular prevented from being pulled out accidentally. In this case, the plug-in electrical connector can advantageously be supplied, for example, together with a secondary fixture.

The captive connection of the fixing element or the secondary fixing means with the plug-in connector is advantageous, but is not absolutely necessary within the scope of the invention.

The preliminary latching position can also be only one position in which the secondary fixing means or fixing element has not yet latched to the plug-in connector, i.e. the position before latching.

According to the invention, the securing element is operatively connected to the blocking insertion device such that during a closing movement of the securing element the blocking insertion device can be moved from an initial position, in which the blocking insertion device blocks a complete insertion of the mating plug-in connector into the plug-in connector, to a release position, in which the blocking insertion device releases a displacement path between the mating plug-in connector and the plug-in connector, in order to fully insert the mating plug-in connector into the plug-in connector.

The fixation element and the obstructive insertion device may be operatively connected, for example such that the obstructive insertion device is positioned in a displacement path of the fixation element, thus being mechanically contacted by the fixation element during a closing movement of the fixation element, and thus being operated or displaced. Alternatively, the fixing element and the obstructive insertion means are formed in one piece or mechanically directly connected to each other, with the result that movements, in particular user manipulations of the fixing element, can be transferred directly to the obstructive insertion means.

Advantageously, a blocking insertion device may be provided which blocks the insertion of the mating plug-in connector into the plug-in connector when the secondary fixing means are not in the final latching position.

According to the invention, the blocking insertion device can be moved from the initial position to the release position in a rotational manner by means of a rotational axis or along the support element.

The electrical plug-in connector with the secondary securing means can be particularly compact since the blocking means do not move linearly from the initial position to the release position, but rather move in a rotational manner from the initial position to the release position. In order to release the displacement path, the blocking insertion device can be pivoted out of the interface or the interior space of the plug-in connector in a rotating manner, instead of being pushed deeper into the interior space or being pushed through the interior space. As a result, the blocking insertion means can be used largely independently of the design of the interior space of the plug-in connector, and the size and configuration of the interface of the plug-in connector are no longer important.

Furthermore, advantageously, the secondary fixing device according to the invention can also be used with and/or for plug-in connectors with a so-called coriolis ring, the outer conductor of which protrudes particularly forward in the plug-in connector (in the direction of the mating plug-in connector).

Advantageously, however, the invention is suitable for replacing existing obstructive insertion means, in particular compact obstructive insertion means, even if no coriolis ring is provided in the plug-in connector. In principle, the invention can be adapted for use with any desired plug-in connector.

The fastening element can have an operating element or an operating region, by means of the operation of which a user, for example an assembler of the plug connector, can initiate the closing movement.

In a refinement of the invention, the closing movement may be a linear movement.

The linear closing movement can be initiated by the user or the assembler of the plug connector in a particularly simple and reliable manner. Furthermore, due to the interaction between the fixing element and the plug-in electrical connector, a linear closing movement can be realized in a relatively simple manner, for example by means of a guide rail of the fixing element provided in the plug-in connector.

In a refinement, the closing movement of the fastening element can also extend orthogonally to the insertion direction of the plug connector.

The insertion direction may be a movement vector along which the mating plug-in connector is inserted into the plug-in connector to close the plug-in electrical connection.

The orthogonal closing movement of the fixing element can firstly be realized in a technically advantageous manner and secondly ensures a particularly robust mechanical fixing of the closed plug connector.

In a refinement of the invention, the blocking insertion device can be moved radially outward from the central axis of the plug-in connector to release the displacement path.

In particular, the interference insertion device can project in its initial position at least partially into the interior of the plug-in connector by means of at least one first (front) end and be moved out of the interior of the plug-in connector by means of a rotational movement, i.e. be pivoted into the release position.

The invention also relates to a plug-in electrical connector for connection to a mating plug-in electrical connector, which plug-in electrical connector has a housing and a blocking insertion device which is designed to block a complete insertion of the mating plug-in connector into the plug-in connector in an initial position and to release a displacement path between the mating plug-in connector and the plug-in connector in a release position, so that the mating plug-in connector is completely inserted into the plug-in connector.

In the plug-in electrical connector according to the invention, the blocking insertion device can be moved from the initial position to the release position by means of a rotation axis or in a rotational manner along the support element.

In a refinement, the blocking insert device can form, together with the fixing element, a secondary fixing device for locking a plug-in electrical connector, which plug-in electrical connector comprises a plug-in connector and a mating plug-in connector.

It is thus advantageously possible to provide a mechanical fixing device in combination with a plug connector and a component hindering the function of the insertion device. The secondary fixing means or the fixing elements of the secondary fixing means can be inserted into the plug-in electrical connector in an initial latching position or in a locking position or in an end position. In the initial latching position, the blocking insertion device belonging to the secondary securing device can block the insertion of the mating plug-in connector into the plug-in connector in a form-fitting manner.

In the locking position or end position of the secondary fixing means or fixing element, the blocking insertion means can be displaced out of the plug-in connector in a rotational manner and thus enables the insertion process.

In a development of the invention, the plug-in connector can comprise an outer electrical conductor, which preferably has a coriolis ring.

The coriolis ring can prevent damage to the easily deformable contact element. The use of coriolis rings for ensuring coriolis safety is known in the art and therefore will not be discussed in further detail.

In this case, the invention is particularly suitable for use with a coriolis ring, since said coriolis ring in a plug-in electrical connector usually projects relatively far forward in the axial direction, with the result that it is usually not possible or not easy to hinder a linear movement of the insertion means deeper into the interface in the radial direction to release the hindered insertion means.

Instead of a coriolis ring, a coriolis wall can also be provided, which can be used in particular in the case of an outer conductor contact having a rectangular cross-sectional profile.

In a development of the invention, the interference insertion means can be designed and arranged to be supported on the outer conductor in an initial position in which the interference insertion means prevents insertion of the mating plug-in connector into the plug-in connector.

Since the interference insertion means are initially supported on the outer conductor, the interference insertion means can particularly firmly prevent the insertion of the mating plug-in connector into the plug-in connector. Since the interference fit is supported on the outer conductor, in particular on the outer conductor coriolis ring, the resistance which can be applied by the interference fit is increased in order to prevent an undesired insertion of the mating plug-in connector.

In a refinement, the axis of rotation can be formed by a rotary joint of the housing of the plug-in connector.

Thus, the fixing element can also be attached to the housing of the plug-in connector or be formed in one piece with the plug-in connector.

In particular, the blocking insertion means can be formed in the manner of a rocker together with the rotary joint. In this case, the first (front) end of the rocker can project into the interface of the plug-in connector in the initial position and prevent the mating plug-in connector from entering the displacement path into the plug-in connector. The second (rear) end of the rocker can finally be arranged in the displacement path of the securing element, so that the securing element operates the second end of the rocker during the closing movement and in this way pivots the first end of the rocker out of the interface of the plug-in connector, at least to the extent that the displacement path is released.

In a refinement, the axis of rotation may extend parallel or orthogonal to the insertion direction of the mating plug-in connector into the plug-in connector.

Both arrangements enable the blocking insertion device to be pivoted out of the displacement path.

Preferably, the axis of rotation extends orthogonally to the insertion direction.

In an alternative refinement of the invention, the insertion-blocking device can have a latching head for blocking the mating plug-in connector and a deformable, preferably elastic, spring arm which extends from the latching head in the direction of the support element.

The latching head can be mechanically stiffened in particular with respect to the spring arm and is therefore designed in particular to absorb forces which act on the blocking insertion device in the insertion direction of the mating plug-in connector, the deformability or elasticity of which forces is smaller than the deformability or elasticity of the spring arm. The retaining head and the spring arms can also be made of different materials in order to provide different elastic properties and the desired deformability, respectively.

In principle, a finger, a stop head or another projection of the blocking insertion device can project into the interface of the plug-in connector to ensure that the mating plug-in connector cannot be fully inserted into the plug-in connector if the secondary fixing means are not in their locking position.

The deformability or elasticity of the spring arms may be chosen such that the spring arms can be bent sufficiently reversibly to perform the required rotational movement or to pivot the retaining head out of the displacement path without undergoing (irreversible) plastic deformation.

In a development of the invention, the support element can be formed by an edge of a recess in the housing of the plug-in connector.

The grooves may in particular be the following: by means of this recess, the blocking insertion means or at least the stop head can be inserted into the plug-in connector to block the insertion of the mating plug-in connector.

In a development of the invention, the spring arms can be supported on the edges of the recess.

Thus, the blocking of the rotational movement of the insertion device can be provided in particular by the combination of the edge with a deformable or elastic spring arm when the end of the spring arm remote from the retaining head is moved.

For example, the securing element can be mechanically connected directly to the retaining head or to the front end of the blocking insertion device, which projects into the displacement path by means of the spring arm, for example can be connected in one piece. Thus, if the fixing element is moved linearly from the preliminary latching position into the latching position, this linear movement can be converted into a rotational movement of the retaining head by means of the spring arm supported on the rim, with the result that the retaining head or the front end is pivoted out of the displacement path by deformation of the spring arm.

In a development of the invention, a primary fixing device can be provided in order to mechanically fix the connection between the plug-in connector and the mating plug-in connector.

The primary fixing means can in particular be one or more latching hooks which engage behind corresponding edges when the plug connector is closed.

The secondary fixing means can mechanically fix the plug-in connector in any desired manner and preferably the secondary fixing means fix the housing of the plug-in connector to the outer conductor of the plug-in connector.

The invention also relates to a plug-in electrical connector having a plug-in electrical connector according to the above and the following embodiments and a mating plug-in electrical connector for connecting to the plug-in connector.

The plug connector can have a secondary fixing device which comprises a fixing element for mechanically fixing the plug connector and an interference insertion device.

The blocking insertion device can be pivoted out of the interface or the interior of the plug-in connector in a rotating manner and in this way releases the interface for mating the plug-in connector by deflection due to the positioning of the secondary fixing means or the fixing element in its locking position.

In contrast to the known prior art, in which the secondary fixing means or fixing element and the blocking insertion means are also simultaneously guided linearly inwards into the plug-in connector, the present rotational movement of the blocking insertion means can be used in a flexible manner for almost any desired plug-in connector, since the interface or the internal structure of the plug-in connector is not critical.

The blocking insert device, which is shaped in the form of a blade arm, can be fastened in a rotationally elastic manner to the secondary fastening device or to its fastening element. In the unloaded state, the blocking insertion device can be positioned in the insertion path of the mating plug-in connector and thus block the insertion process. If the secondary fixing means or its fixing element is moved into the locking position, the blade-arm-like interference insertion means can be rotated about the center of rotation by a stop on the housing of the plug-in connector, as a result of which the blade-arm-like interference insertion means can be moved out of the insertion path of the mating plug-in connector. The insertion process can be initiated in this way.

The blade-arm-like interference insertion means can also be fastened in a rotationally elastic manner to the housing of the plug-in connector. In the unloaded state, the blocking insertion device can be positioned in the insertion path of the mating plug-in connector and thus block the insertion process. If the secondary fixing means or its fixing element is moved into the locking position, the blade-arm-like interference insertion means can be rotated about its center of rotation by the secondary fixing means. The insertion process can also be initiated in this way.

Advantageously, a plug-in connector according to the invention or a plug-in connection according to the invention can be provided for the transmission of large amounts of data. In particular, use in the automotive field, for example for transmitting high bit rate data signals in connection with autonomous driving, driver assistance systems, navigation, infotainment and data transmission of a plurality of cameras, sensors or screens, may be provided.

Preferably, the plug-in electrical connector may be designed as a FAKRA plug-in connector or a High-Speed FAKRA Mini (HFM) plug-in connector. However, the electrical plug-in connection can in principle be designed in any desired manner. The use of a secondary fixing means is advantageous for a large number of plug-in connectors.

Of course, the features already described in connection with the secondary fixture and the plug-in electrical connector can also be used advantageously for a plug-in electrical connector and vice versa. Furthermore, the advantages already mentioned in connection with the secondary fixture or the plug-in electrical connector may also be understood in connection with the plug-in electrical connector and vice versa.

Further, it should be noted that terms such as "comprising", "having" or "having" do not exclude any other features or steps. Furthermore, terms such as "a" or "the" refer to a single step or feature and do not exclude a plurality of features or steps and vice versa.

Detailed Description

Fig. 1 and 2 show a plug-in electrical connector 1 according to the invention in a partially inserted state (see fig. 1) and in a plugged-in state (see fig. 2). The plug-in electrical connector 1 has a plug-in electrical connector 2 and a mating electrical plug-in connector 3 for connection to the plug-in connector 2.

The electrical plug-in connector 2 has a housing 4 and an outer conductor 5 accommodated in the housing 4. The outer conductor 5 surrounds an inner electrical conductor which is guided in the outer conductor 5 and is electrically insulated from the outer conductor 5 by a dielectric. However, this is not important in the context of the present invention, and therefore the inner conductor and dielectric are not shown in the exemplary embodiment for a simpler explanation of the present invention. The outer conductor 5 and the inner conductor or plug-in electrical connector 2 (and also the mating electrical plug-in connector 3) can be further connected to an electrical cable, an electrical printed circuit board or another electrical module (likewise not shown).

The mating electrical plug-in connector 3 likewise has a housing 6, wherein the housing 4 of the plug-in electrical connector 2 and the housing 6 of the mating electrical plug-in connector 3 are designed such that the two housings can be inserted one into the other.

In an exemplary embodiment, a primary fixing means 7 for fixing the plug-in connector 1 is provided, which is formed by latching hooks 8 on the housing 6 of the mating plug-in connector 3, which latching hooks can engage behind corresponding edges 9 of latching elements 10 on the housing 4 of the plug-in connector 2 and in this way fix the plug-in electrical connector 1 against being pulled out in the closed state.

Fig. 3 shows the electrical plug-in connector 2 of fig. 1 and 2 in isolation, seen from below, without the outer conductor 5. The plug-in electrical connector 2 has a secondary fixing means 11 for locking the plug-in connection 1. The secondary fixing means 11 comprise a fixing element 12 and an obstruction insertion means 13 (see in particular fig. 8).

In an exemplary embodiment, the fixing element 12 of the secondary fixing means 11 can enter a circumferential groove of a sleeve positioned around the outer conductor 5 (not shown) and, by means of one or more locking lugs 14 (see fig. 8), into a recess 15 (see, for example, fig. 1, 2 and 9) of the housing 4 of the plug-in connector 2 and thus fix the housing 4 of the plug-in connector 2 to the sleeve surrounding the outer conductor 5.

The securing element 12 can be moved by a closing movement B from a preliminary latching position (see fig. 3 to 5) into a locking position (see fig. 6 and 7), in which the securing element 12 mechanically secures the plug connector 1.

The closing movement B is a linear movement and preferably moves orthogonally to the plug-in direction S of the plug connector 1. The blocking insertion means 13 can be pivoted radially outwards from the central axis M of the plug-in connector 2 in order to release the displacement path of the mating plug-in connector 3 into the plug-in connector 2.

In this case, the securing element 12 is operatively connected to the blocking insertion device 13 such that during the closing movement B of the securing element 12 the blocking insertion device 13 can be moved from an initial position (see, for example, fig. 5), in which the blocking insertion device 13 blocks the full insertion of the mating plug-in connector 3 into the plug-in connector 2, to a release position (see, for example, fig. 7), in which the blocking insertion device 13 releases the displacement path between the mating plug-in connector 3 and the plug-in connector 2, so that the mating plug-in connector 3 is fully inserted into the plug-in connector 2.

According to a first embodiment, shown in figures 3 to 8, the interference insertion means 13 can be moved in a rotary manner along the support element 16 (see figures 5 and 7) from an initial position to a release position.

The blocking insertion device 13 has a stop head 17 for blocking the mating plug-in connector 3 and a deformable, preferably elastic, spring arm 18 which extends from the stop head 17 in the direction of the support element 16. In an exemplary embodiment, the support element 16 is formed as an edge of a recess in the housing 4 of the plug-in connector 2, wherein the spring arm 18 is supported on the edge of the recess. As a result, the blocking insertion device 13, or at least its stop head 17, can be pivoted out of the displacement path of the mating plug-in connector 3 when the fixing element 12 or the secondary fixing device 11 is operated linearly. This principle is demonstrated especially when figures 5 and 7 are taken together.

The retaining head 17 is designed in an enhanced manner compared to the spring arm 18. Preferably, the stop head is supported on the edge 16 by means of a support region 17a, so that in the event of undesired insertion of the mating plug-in connector 3, forces acting on the stop head 17 are introduced into the plug-in connector 2 via the edge 16.

Preferably, the interference insertion means 13 can be supported on the outer conductor 5 in an initial position in which the interference insertion means 13 prevents the insertion of the mating plug-in connector 3 into the plug-in connector 2, as shown in fig. 5. Preferably, the outer electrical conductor 5 of the plug-in connector 2 is designed as a coriolis ring to prevent damage to the outer conductor 5 when the mating plug-in connector 3 is inserted at an angle.

According to a second embodiment of the invention, the blocking insertion device 13 can be moved from the initial position to the release position by means of a rotation of the axis of rotation a in the form of a rocker, as shown in fig. 9 and 10.

In this case, the axis of rotation a may be formed by a rotary joint of the housing 4 of the plug-in connector 2. In the exemplary embodiment, this axis of rotation a extends orthogonally to the insertion direction S of the mating plug-in connector 3 into the plug-in connector 2. However, the axis of rotation can also extend in principle parallel to the plug-in direction S of the mating plug-in connector 3, as shown in fig. 9 by showing an alternative axis of rotation a_AltAs shown.
