Description

TECHNICAL FIELD

[0001] The invention relates to a plug connector for connection with a circuit board, wherein the plug connector has a plug connector housing and electrical contact parts for contacting counter contact parts of a counter plug connector which can be connected with the plug connector, and wherein the plug connector has a separately formed solder anchor which is arranged at the plug connector housing for mechanically securing the connection of the plug connector with the circuit board. BACKGROUND

[0002] Plug connectors for connection with a circuit board are known in the field of electrical installation. Such plug connectors are arranged on a circuit board and are mechanically and electrically connected with the circuit board. The plug connectors can have corresponding solderable connection faces as contact areas for electrical connection to the circuit board. In order to protect the mechanical connection between the plug connector and the circuit board from unintentional separation, for example due to tensile forces acting on the plug connector, it is known to additionally secure the plug connector at the circuit board by means of a so-called solder anchor or a plug-in solder anchor, in such a way that the solder anchor is fastened at the plug connector housing of the plug connector and is connected with the circuit board in a material-fit. Such solder anchors must be relatively robust in construction in order to guarantee a sufficient mechanical securing, which generally requires a considerable additional construction space at the plug connector. Furthermore, the potential properties of the solder anchor with regard to the required air clearance and creepage distance must be taken into account, which also has an influence on the structural design and dimensioning of the plug connector. SUMMARY

[0003] Against this background, it was the object underlying the invention to realize an improved plug connector with a solder anchor which is connected at the plug connector with reduced construction space requirement and still guarantees a reliable mechanical securing.

[0004] The object is achieved by means of a plug connector according to the invention and a kit with a plug connector and a solder anchor according to the invention. Advantageous embodiments are disclosed in the description and the drawings.

[0005] Such a plug connector for connection with a circuit board has a plug connector housing and electrical contact parts for contacting mating contact parts of a mating plug connector connectable with the plug connector, and has a solder anchor which is formed separately, i.e. shaped, with respect to the plug connector housing and the electrical contact parts, wherein the solder anchor is arranged at the plug connector housing and constitutes a mechanical securing for the connection of the plug connector with the circuit board, it is proposed for the plug connector that the solder anchor is formed as a substantially flat planar member and has a solder section at a first anchor side for connection with the circuit board and a curved locking section at a second anchor side opposite the first anchor side for form-fitting engagement into a locking opening of the plug connector housing, wherein the solder section and the locking section are connected to one another via a connecting section, and wherein a fastening section protrudes from the connecting section, which fastening section is form-fittingly accommodated in a solder anchor accommodation of the plug connector housing.

[0006] Briefly, a plug connector with a solder anchor is proposed, which can be arranged particularly position-savingly at the plug connector by a planar structural shape and which does not significantly increase the extension of the plug connector in the region of the solder anchor, in particular in a separation direction of the plug connector, which can correspond to the direction of the parallel arrangement of the electrical contact parts of the plug connector. By the realizable lowering of the solder anchor into the solder anchor accommodation in the plug connector housing at least in the fastening section, the characteristic of the flat configuration of the proposed anchor solution is further enhanced. At the same time, the solder anchor is mechanically secured at the plug connector housing via the fastening section and the locking section in multiple, so that a robust and loadable use of the solder anchor is achieved despite the compact structural shape. In particular, the solder anchor can be secured at the plug connector housing via different form-fitting directions in the fastening section and the locking section for an improved loadability in different orientations of the force action, as will also be set out below. As a result, a plug connector with an advantageously small size but still loadable solder anchor can be provided.

[0007] "Separately" is understood as a solder anchor which is manufactured separately from other components of the plug connector and which is handled as a single part during manufacturing and installation, which is placed onto the plug connector as a separate part. The separate solder anchor remains detachable from the plug connector by a form-fitting connection only with the plug connector, in particular the plug connector housing. The solder anchor is not materially connected with other parts of the plug connector.

[0008] According to the proposed feature, the solder anchor is configured as a substantially planar planar member. A planar member can be understood as a planar member which has a length extension and a width extension which are significantly greater than a depth extension. The planar member can be embodied, for example, as a plate member. In particular, it is punched from a plate blank, for example of metal. With the substantially planar planar member, in particular a planar member is described which has a surface which is largely planar. For example, at least 70%, at least 80% or at least 90% of the share of the continuous surface side of the planar member extends in a common plane. The solder anchor can in particular have a straight or planar, uncurved course in addition to the locking section.

[0009] The solder anchor has a first anchoring side and a second anchoring side, wherein the second anchoring side is opposite the first anchoring side. In other words, the first and second anchoring sides can represent two opposite end sections of the solder anchor. The first anchoring side can be directed toward a circuit board side of the plug connector housing, which is designed for placement on a circuit board, while the second anchoring side can be directed away from the circuit board side and can, for example, project in the direction of a housing upper side of the plug connector housing which is opposite the circuit board side.

[0010] The solder section of the solder anchor can be, for example, a region of the solder anchor which is designed for a material-fit fastening at the circuit board. The solder section can be shaped, for example, as a solder pin, i.e. has an elongate, straight extension. The locking section can be embodied as a material web, for example, which is substantially rectangular in shape. The locking section can have substantially the same width as the solder section, wherein a width direction of the solder anchor can be defined transversely to a main extension direction of the solder anchor along its greatest extension. The locking section can have a smaller length than the solder section, wherein a length direction of the solder anchor along the main extension direction of the solder anchor can be defined according to its greatest extension.

[0011] According to the proposed feature, the locking section is bent for form-fitting engagement into a locking opening of the plug connector housing. The feature can be present at the plug connector, in particular in a final installation state of the soldering anchor. In an intermediate installation state, the soldering anchor can be provided as a flat planar member without a bent portion at the plug connector and can be transferred into the final installation state by bending the locking section into the locking opening. By implementing the soldering anchor as a planar member, such a bending process can be achieved without the aid of large force expenditure. The locking opening can be, for example, a recess in the plug connector housing opposite the locking section, which is surrounded by housing edges delimiting the locking opening. The bent locking section can project into the locking opening and form an undercut with at least two adjoining housing edges, so that an oriented form fit can be formed. By engaging the bent locking section into the locking opening, it can be ensured, in particular in the case of a tensile force introduction into the plug connector, that the soldering anchor is reliably supported at the plug connector housing. For example, in the case of a tensile force opposite the plug-in direction of the plug connector or at a right angle opposite the circuit board, the tensile force can cause a counter-rotation of the plug connector housing and the soldering anchor, which is inhibited by engaging the locking section into the locking opening, and which is discharged as a total force into the soldering section of the soldering anchor connected to the circuit board. In particular, a tensioning between the soldering anchor and the plug connector housing can be achieved by separate fixing points of the soldering anchor in the fastening section and in the locking section.

[0012] According to the proposed feature, the soldering section and the locking section are connected to one another via a connecting section. The connecting section can extend in a straight course between the soldering section and the locking section, so that the soldering section and the locking section extend substantially along a common straight line without being laterally offset from one another. The connecting section can have a greater length than the locking section. The connecting section can be, for example, at least as long as the soldering section.

[0013] According to the proposed feature, a fastening section projects from the connecting section. The fastening section projects, in particular, transversely in the width direction of the soldering anchor. The fastening section can have a greater width extension than the locking section and the soldering section. The fastening section can have a greater length extension than the locking section. The fastening section can have a smaller length extension than the soldering section. The fastening section can have fastening elements, for example form-fitting contours and / or latching elements, for fixing the soldering anchor at the plug connector housing.

[0014] If a pulling force occurs which is oriented perpendicular to the circuit board, a torque results from this onto the plug connector housing, which is transferred onto the solder anchor. Here, two different opposing torques act onto the solder anchor. At the locking section, a force acts in the plug-in direction, while at the fastening section a force acts which is directed away from the circuit board. These two forces result in opposing torques at the solder anchor, which compensate for each other as far as possible, so that the solder anchor is not twisted, but only loaded with a pulling force. This is advantageous for the solder connection and the entire arrangement (plug connector housing without rotation).

[0015] The fastening section is accommodated in a form-fit manner in a solder anchor accommodation of the plug connector housing. The solder anchor accommodation can in particular be a material cutout with a form-fit contour in the plug connector housing, into which the solder anchor can be arranged in a form-fit manner. In particular, the solder anchor can form an undercut with the form-fit contour of the solder anchor accommodation at least on two sides, so that an oriented form-fit can be formed. The solder anchor accommodation can be formed at a housing outer face of the plug connector housing. The solder anchor accommodation can be formed at an end side of the plug connector housing, wherein the end side can extend substantially perpendicular to a contact side of the plug connector for contacting a mating plug connector and perpendicular to a circuit board side of the plug connector housing.

[0016] According to one embodiment, a first form-fit direction between the fastening section and the solder anchor accommodation can extend substantially perpendicular to a second form-fit direction between the locking section and the locking opening. Thereby, it can be achieved that the solder anchor is held in a form-fit manner at the plug connector housing in multiple spatial directions, so that the solder anchor is securely and loadable fastened at the plug connector housing even under force action from different directions. The respective form-fit directions can be defined by the direction of the normal force acting between the form-fit contour of the solder anchor and a corresponding counter-contour of the plug connector housing. The form-fit direction between the fastening section and the solder anchor accommodation can for example extend parallel to the extension direction of the plug connector housing between the circuit board side and a housing upper side opposite the circuit board side of the plug connector housing. The form-fit direction between the locking section and the locking opening can for example extend parallel to the plug-in direction of the plug connector for connecting the plug connector with a counter plug connector. By the mutually orthogonal form-fit directions of the different sections of the solder anchor, it is ensured that the solder anchor is particularly securely held at the plug connector housing.

[0017] According to one embodiment, an exposed contact surface can be formed on a surface of the solder anchor facing away from the plug connector housing. In other words, the solder anchor can be arranged at the plug connector housing mainly uncovered by the plug connector housing. For example, at least 80% or at least 90% of the surface of the solder anchor facing away from the plug connector housing can be arranged uncovered. For example, the solder anchor can be only partially surrounded by the plug connector housing in the region of the form-fit undercut by means of the plug connector housing. The uncovered contact surface can be configured for contacting a shielding element which can be arranged at the plug connector housing under the condition of contacting the uncovered contact surface of the solder anchor.

[0018] According to one embodiment, the solder anchor accommodation of the plug connector housing can have an introduction opening. The introduction opening serves for pushing the solder anchor into the solder anchor accommodation along a housing face of the plug connector housing in a predefined introduction direction. Thereby, the fastening of the solder anchor at the plug connector housing can be carried out in a simple manner, wherein the configuration of the solder anchor as a planar component can advantageously be used for guiding the solder anchor along the housing face. The introduction opening can for example be formed between the aforementioned housing tabs for guiding the fastening section. The introduction direction can be parallel to a plug-in direction of the plug connector for connecting with a counter plug connector.

[0019] According to one refinement, the introduction direction of the solder anchor into the solder anchor accommodation is oriented counter to the plug-in direction of the plug connector for connecting with a counter plug connector. Thereby, it is avoided that the solder anchor is unintentionally released and possibly pushed out of the solder anchor accommodation in connection therewith due to a mechanical contact with components of the counter plug connector during the plug-in process.

[0020] According to one embodiment, at the fastening section of the solder anchor a catch element can be provided, which is configured for catching on a counterpart catch element of the solder anchor receptacle and / or for embedding in the material of the plug connector housing within the solder anchor receptacle by means of a pointed edge region. Thereby, a reliable and secure fastening of the solder anchor at the plug connector housing is possible. According to one design possibility, the fastening section can have two catch elements, which can be caught with correspondingly provided counterpart catch elements of the solder anchor receptacle, so that a uniform and secure catching is achieved. The catch elements of the solder anchor can be, for example, catch hooks and the counterpart catch elements of the solder anchor receptacle can be, for example, catch protrusions with a catch edge, which can be engaged from behind by the catch hooks. The fastening section can have a catch section, at which the catch elements are provided. The catch section of the fastening section can be formed at an end section of the fastening section, which faces away from the connection section. The solder anchor can be introduced or introduced into the solder anchor receptacle by means of the catch section.

[0021] According to one embodiment, the solder anchor receptacle of the plug connector housing can have two parallel, bridging housing webs for guiding the fastening section of the solder anchor in the solder anchor receptacle. Thereby, the solder anchor can be safely and definedly transferred into the fastening at the plug connector housing. The housing webs can have a geometric guiding profile, for example a stepped profile or a bevel profile, for forming a dovetail profile, so that a secure form-fit guiding of the fastening section in the solder anchor receptacle is achieved. According to one design possibility, the aforementioned counterpart catch elements can be molded to the housing webs and project therefrom, so that the fastening section of the solder anchor, which is provided with catch elements, can be introduced along the housing webs into a catching position, in which the catch elements can be caught with the counterpart catch elements.

[0022] According to one embodiment, at the connection section of the solder anchor a standing-off web can be formed, which projects from the connection section and serves for supporting the solder anchor at a housing edge of the plug connector housing. By means of the standing-off web, an additional force absorption at the solder anchor is possible and the standing-off web is additionally stabilized at the plug connector housing. Furthermore, the solder anchor can be fixed by the standing-off web against displacement in the direction of a housing upper side of the plug connector housing, which faces away from the circuit board side. In the case of suitable design solutions, it is also possible to achieve a tensioning of the solder anchor between the standing-off web, which is supported at the housing edge, and a locking section, which is supported at a housing edge, which delimits a locking opening. The standing-off web can project transversely from the connection section. In particular, two standing-off webs can project from the connection section at opposite sides, so that a cross-shaped standing-off region is formed.

[0023] According to one embodiment, the solder anchor accommodated in the solder anchor accommodation can be at least sectionally flush with a housing wall of the plug connector housing which adjoins the solder anchor accommodation. In particular, a solder anchor having a fastening section which is sunk into the solder anchor accommodation can be flush with a housing edge which adjoins the solder anchor accommodation. This can be achieved in particular by the solder anchor being configured as a substantially flat planar member. By virtue of the at least sectional flushness, it is possible to provide further fitting elements, for example a locking claw, on the housing side of the plug connector which is provided with the solder anchor, the locking claw serving to lock the plug connector at a counterpart plug connector which is connected to the plug connector. Furthermore, the solder anchor is subjected to minimal requirements in terms of installation space at the plug connector in its direction of separation.

[0024] According to one embodiment, the plug connector housing can have two solder anchor accommodations which are configured on two mutually opposite outer sides of the plug connector housing. Thereby, it is achieved that the solder anchor is optionally provided at one or the other outer side of the plug connector housing. Furthermore, it is also conceivable that the plug connector housing is fixed at a circuit board by means of two solder anchors which are each placed at an outer side. Since the solder anchor is configured as a separate and flat planar member in the intermediate installation state, the locking section of the solder anchor can be bent into the respective direction of the locking opening of the plug connector housing after the solder anchor has been installed at the plug connector housing in order to be transferred into the final installation state. Thereby, it is possible to achieve a versatility of the solder anchor for both outer sides of the plug connector housing. The mutually opposite outer sides of the plug connector housing can form end sides of the plug connector housing, wherein the end sides can extend substantially perpendicularly to a contact side of the plug connector for contacting a counterpart plug connector and can extend perpendicularly to a circuit board side of the plug connector housing.

[0025] According to one embodiment, the solder anchor can be manufactured as a stamped part. Thereby, a simple and cost-beneficial provision of the solder anchor is possible. A stamped part can be regarded as a thin sheet part having a complex outer contour, which is manufactured by cutting a sheet semi-finished product. By means of the stamped part, it is possible to provide a substantially flat planar member, for example, which can be bent in order to bend the locking section of the solder anchor without the expenditure of greater forces.

[0026] According to one embodiment, the plug-in connector can be embodied as a contact pin row or as a socket row. Such plug-in connectors can be fixed at a circuit board by means of a solder anchor, however at the same time occasionally in practice are subjected to force influences from different directions, which require a reliable and loadable mechanical connection, so that a solder anchor according to the aforementioned features can advantageously be used for said plug-in connection type. Furthermore, it can be desirable for a contact pin row or a socket row to be provided with a connected shielding element and / or a locking claw, which can advantageously be achieved, for example, by means of an exposed contact face and a flush portion of the solder anchor. A contact pin row can be a plug-in connector having at least two electric contact pins arranged side by side in a separating direction of the plug-in connector. A socket row can be a plug-in connector having at least two electric contact pin receptacles arranged side by side in a separating direction of the plug-in connector.

[0027] The invention also relates to a kit having a plug-in connector and a solder anchor for forming a plug-in connector according to one of the aforementioned features. The aforementioned advantages of the plug-in connector can also be achieved with such a kit, wherein the solder anchor can optionally be provided at the plug-in connector, in particular at different outer sides of the plug-in connector housing, as a spare part component. In the kit, the solder anchor can be embodied as a flat planar component and can be fastened at the plug-in connector by pushing into a solder anchor receptacle, in order to then be mechanically fixed at the plug-in connector housing by bending the locking section into a locking opening of the plug-in connector housing. According to one design possibility, the kit can have a plug-in connector and at least two solder anchors of the same type. Furthermore, a mating plug-in connector matching the plug-in connector can be another component of the kit, so that a plug-in connector arrangement can be produced with the kit.

[0028] In general, the word "a" will be understood to mean "at least one" when used in this application, except where otherwise indicated by context. BRIEF DESCRIPTION OF DRAWINGS

[0029] The invention allows different embodiments and will be explained in detail in the following with the aid of the drawings. The drawings show schematically:

[0030] Figure 1 a perspective side view of a plug-in connector having a solder anchor according to one embodiment is shown;

[0031] Figure 2 a separate perspective view of a solder anchor according to Figure 1 ;

[0032] Figure 3 a top view of a plug-in connector according to Figure 1 ;

[0033] Figure 4 a cross-sectional side view along the cutting line shown in Figure 1 Fig. 2 of the plug connector according to one embodiment. Figure 3 Fig. 3 shows a cross-sectional side view along the cutting line shown in DETAILED DESCRIPTION

[0034] Figure 1 , Figure 3 and Figure 4 Fig. 1 shows different views of a plug connector 1 according to one embodiment designed for connection with a circuit board, embodied as a contact pin row, with a solder anchor 4. Figure 2 The solder anchor 4 is additionally shown in a separate perspective view. The plug connector 1 and the solder anchor 4 can be provided as a kit.

[0035] The plug connector 1 has a plug connector housing 2 and an electrical contact 3 embodied as a contact pin for contacting a counter contact of a not shown counter plug connector connectable with the plug connector 1. As can be seen, for example, in Figure 1 Fig. 2, the solder anchor 4 is embodied separately and is arranged at the plug connector housing 2. The solder anchor 4 serves for mechanical securing of the connection of the plug connector 1 with a not shown circuit board.

[0036] As can be gathered, in particular, from Figure 1 , Figure 3 and Figure 4 , the solder anchor 4 is embodied as a substantially flat planar member, so that a space-saving arrangement of the solder anchor 4 at the plug connector housing 2 is achieved and the extension of the plug connector 1 in the separation direction 27 is not significantly increased. The planar member can be manufactured, for example, as a stamped part, in particular from a sheet semi-finished product of metal. As can be seen in Figure 2 Fig. 2, the solder anchor 4 as a planar member has a significantly greater extension in the length direction L and in the width direction B than in the depth direction T.

[0037] The solder anchor 4 has a pin-like solder section 5 at a first anchoring side 6. The solder section 5 serves for connecting the solder anchor 4 with a circuit board. Furthermore, the solder anchor 4 has a second anchoring side 9 opposite the first anchoring side 6, as can be seen in Figure 1In the state of the art, a locking section 7 with a bend is provided for form-fitting engagement into a locking opening 8 of the plug connector housing 2, which is formed by a recess in the plug connector housing 2. A first anchoring side 6 and a second anchoring side 9 are assigned to end sections of the solder anchor 4 which are opposite one another. The first anchoring side 6 is directed toward a circuit board side 28 of the plug connector housing 2. The second anchoring side 9 is directed toward a housing upper side 29 of the plug connector housing 2 which is opposite the circuit board side 28. The locking section 7 is embodied as a curved material web and has a rectangular basic shape. The locking section 7 is transferable from a straight, flat orientation in a pre-assembly state and an intermediate assembly state into a curved orientation for engagement into the locking opening 8 by a bending process.

[0038] The solder section 5 and the locking section 7 are connected to one another via a connecting section 10 of the solder anchor 4 as shown in detail in Figure 2 The connecting section 10 can have a greater extension in the length direction L than the locking section 7 and at least as great an extension in the length direction L as the solder section 5 as shown. Projecting from the connecting section 10 is a fastening section 11 which is form-fittingly accommodated in a solder anchor accommodation 12 of the plug connector housing 2 as shown in Figure 1 and Figure 4 The fastening section 11 can have a greater extension in the width direction B than the solder section 5 and the locking section 7 as shown in Figure 2 Furthermore, the fastening section 11 can have a greater extension in the length direction L than the locking section 7 and a smaller extension in the length direction L than the solder section 5 or the connecting section 10.

[0039] Between the fastening section 11 and the solder anchor accommodation 12, a form fit with a first form fit direction 13 can be formed by an overlap of the form fit contours of the fastening section 11 and the solder anchor accommodation 12. Furthermore, between the locking section 7 and the locking opening 8, a further form fit with a second form fit direction 14 can be formed by an overlap of the locking section 7 and the adjoining housing edge. It can be gathered from Figure 1 that the first form fit direction 13 between the fastening section 11 and the solder anchor accommodation 12 extends substantially perpendicularly to the second form fit direction 14 between the locking section 7 and the locking opening 8. Thereby, it is ensured that the solder anchor 4 is held particularly reliably at the plug connector housing 2.

[0040] Furthermore, Figure 1 It is shown in that an exposed contact surface 15 is formed on a surface of the solder anchor 4 which faces away from the plug connector housing 2, so that, for example, a shielding element can be provided at the plug connector housing 2 and the solder anchor 4, so that a shielding transition between the contact surface 14 and the shielding element is possible.

[0041] It is apparent from the combination of Figure 1 , Figure 3 and Figure 4 that the welding anchor receptacle 12 of the plug connector housing 2 has an introduction opening 16 for pushing the welding anchor 4 into the welding anchor receptacle 12 along a housing face 17 of the plug connector housing 2 in a predefined introduction direction 18, so that a simple fastening of the welding anchor 4 at the plug connector housing 2 is possible and the planar property of the welding anchor 4 can be used for a push-in fastening along the housing face 17. The introduction direction 18 of the welding anchor 4 into the welding anchor receptacle 12 is here oriented opposite to the plug-in direction 19 of the plug connector 1 for connecting with a counterpart plug connector, as can be seen in Figure 1 and 4 , so that the fastening of the welding anchor 4 at the plug connector housing 2 is not influenced by the plug-in process between the plug connector 1 and the counterpart plug connector.

[0042] As can be seen in Figure 4 , two latching elements 20 are provided at the fastening section 11 of the welding anchor 4 for latching at two corresponding counterpart latching elements 21 of the welding anchor receptacle 12, so that a simple and reliable fixation of the welding anchor 4 at the plug connector housing 2 is achieved. The latching elements 20 can be configured as latching hooks as shown. The area of the fastening section 11 in which the latching elements 20 are provided can be referred to as latching section. The welding anchor 4 can be introduced into the welding anchor receptacle 12 by means of the latching section. The counterpart latching elements 21 can be configured as latching protrusions with latching edges as shown, which can be engaged from behind by the latching hooks.

[0043] Figure 1 It is further shown in Figure 1 that the welding anchor receptacle 12 of the plug connector housing 2 has two parallel, bridging housing webs 22 across the welding anchor 4 for guiding the fastening section 11 of the welding anchor 4 in the welding anchor receptacle 12, so that a defined guidance of the welding anchor 4 in the welding anchor receptacle 12 is possible and the push-in fastening is facilitated. Figure 1 It is explicitly apparent from Figure 1 that the housing webs 22 have a bevel profile for forming a dovetail profile, so that a form-fit guiding profile results.

[0044] Furthermore, for example Figure 1 and Figure 4As can be seen from the figures, at the connection section 10 of the soldering anchor 4 there is formed an abutment tab 23 which projects from the connection section 10, for supporting the soldering anchor 4 at the housing edge 24 of the plug connector housing 2, so that an additional tensioning of the soldering anchor 4 at the plug connector housing 2 can be achieved. According to the illustrated embodiment, an abutment region in the shape of a cross with two opposite abutment tabs 23 is formed here.

[0045] From Figure 3 It can be gathered from the figures that the soldering anchor 4 accommodated in the soldering anchor accommodation 12 is at least sectionally flush with a housing wall portion 25 of the plug connector housing 2 which adjoins the soldering anchor accommodation 12, so that further fitting elements, such as shielding elements or locking claws, can be arranged at the plug connector 1 in a simple and soldering anchor 4- independent manner.

[0046] Furthermore, Figure 3 It is shown in the figures that the plug connector housing 2 has two soldering anchor accommodations 12 which are formed on two mutually opposite outer sides 26 of the plug connector housing 2. The outer sides 26 form end sides of the plug connector housing 2 here. The soldering anchor 4 can optionally be placed at one of the outer sides 26 or two soldering anchors 4 can be arranged at the two outer sides 26 as universal pieces here. The mounting of the soldering anchor 4 at the associated soldering anchor accommodation 12 can be carried out in such a way that in a first mounting step the accommodation of the soldering anchor 4 in the soldering anchor accommodation 12 is achieved via the fastening section 11 (intermediate mounting position). Subsequently, the bending of the locking section 7 into the locking opening 8 takes place.

[0047] By means of the plug connector 1 and the soldering anchor 4 described according to the preceding embodiments, a reliable securing of the mechanical connection between the plug connector 1 and the circuit board is achieved. The soldering anchor 4 can be fastened at the plug connector 1 in a simple and secure manner and is a connection component of the very thin construction of the plug connector 1 which is nevertheless mechanically loadable due to the proposed fastening design of the soldering anchor 4 at the plug connector 1.
