The invention relates to a plug connector housing, that is, to a female plug or pin connector housing for an electric plug connector of an airbag, in particular, an airbag of a motor vehicle. The invention further relates to an electrical plug connector or a conjugate plug electrical connector, and also to an electrical plug connection, in particular, for an electric clock spring connection, or an electrical coupling, to a plug connector housing according to the invention, or to an electric plug connector according to the invention, and to a plug connector housing conjugated in correspondence with this, or to an electric plug connector conjugated in correspondence therewith.

Electrical plug connectors, or plug connections, for a releasable mechanical and electrical connection for electrical wires and terminals are known in a large number of embodiments. In the case of plug connectors, the cables are usually mechanically and electrically connected to electrical contact elements (female or pin plug contact) by drawing and / or compaction welding, so that the electrical contact elements are arranged and usually block inside the contact chambers of a plug connector housing.

The electrical plug connectors are subject to the requirement that the charges originated by the cables, such as, for example, the movements of the cables and / or the vibrations of the cables as a result of harsh environmental conditions, for example, in a The motor vehicle must not be transferred either to the electrical connection between the cable and the electrical contact element, or to the electrical connection between two contact elements of a plug connection. While the mechanical loads acting on the electrical plug connector or plug connection can be held at bay by an independent member arranged behind the electrical plug connector, or before and after the plug connection, in order to intercept the wires connected to the electrical contact elements, this disadvantageously increases the number of parts, the costs and the complexity of the assembly.

EP 1 204 172 A1 describes an electrical connector that can be connected to at least one conductive wire. The connector comprises a housing that has a recess to receive an electrical contact element through a service opening. The electrical contact element can be fixed inside the housing. The housing additionally comprises a cover that has been designed to cover the service opening.

It is a purpose of the invention to disclose an improved plug connector housing for an electrical plug connector or an improved electrical plug connector. In particular, it is a purpose of the invention to provide, while keeping the number of parts, costs and complexity of the assembly low, a fixing of an electric contact element and a cable within / in the connector housing of plug. Preferably, this should be achieved by a single fixing element. On the other hand, it is a purpose of the invention to disclose an electrical plug connection in an electrical plug connector according to the invention, and an electrical plug connector connected thereto.

The purpose of the invention is achieved by means of a plug connector housing according to claim 1, an electrical plug connector according to claim 9, and an electrical plug connection according to claim 10.

The plug connector housing according to the invention has a single fixing element, made of one or more parts, to secure an electrical contact element and to secure a cable inside / in the plug connector housing. In this case, the fixing element makes it possible for the electrical contact element to be retained within the plug connector housing and, at the same time, for the cable to be secured in the plug connector housing.

In a preferred embodiment of the invention, the fixing element has a blocking member intended to secure the electrical contact element, and a clamping member intended to secure the cable. This allows the electrical contact element to be secured within the plug connector housing in a locked position of the fixing element or of the blocking member. On the other hand, the cable can be retained in the plug connector housing in an embraced position of the fixing element or of the hugging member.

In preferred embodiments of the invention, the fixing element, or only the blocking member, or only the hugging member, or the blocking member and the hugging member, are joined in one piece, in particular, materially in One piece, to the plug connector housing. In this last embodiment, it is possible to configure the respective locking member and the embracing member (materially) of a single piece with the plug connector housing, or providing the (materially) embracing member of a single piece with the member lock, which is then configured for one piece with the plug connector housing.

The plug connector housing according to the invention is distinguished by its simple and rapid manufacturing. Additionally, the plug connector housing according to the invention only requires a single injection mold, has a low overall height and a compact design. In particular, it is advantageous that the design of the plug connector housing comprising electrical contact elements does not require additional parts, such as cable ties or a winding strip, to secure, on the one hand, the element of electrical contact inside the plug connector housing and, on the other hand, the cable in the plug connector housing. This provides the advantage of a simple treatment susceptibility by a manufacturer and also, due to its construction, of free access in terms of equipping the plug connector housing with contact elements. On the other hand, the cable fixing according to the invention also serves as a member of additional stress release.

The invention can be easily implemented in a female plug and / or in an electrical plug connection plug, so that it advantageously provides a cable fixing according to the invention on both sides of the plug connection, for example, a floating electrical coupling.

In a preferred embodiment of the invention, the fixing element pivots with respect to the plug connector housing by means of a first joint, preferably a film joint. In this case, it is preferable that the blocking member and the clamping member of the fixing element are joined together by means of a second joint, preferably a film joint. In this case, it is, again, preferable that the locking member is connected to the plug connector housing by means of the first joint, preferably a film joint, and that the hugging member is connected to the locking member, of again, by means of the second joint, preferably a film joint. In other words, the hugging member mechanically connects to the locking member. The hugging and locking members form the fixing element according to the invention, whose hugging member is articulated with the plug connector housing.

Preferably, the locking member and the hugging member are each configured as substantially parallel and straight tongues that can be placed one supported on the other or an envelope

another in the plug connector housing, such that the locking member and the hugging member adopt, when they are placed supported on the other, their locked position and their embraced position, respectively.

If both the blocking member and the hugging member are in their respective open position (the blocking member is not in the locked position and the hugging member is not in the embraced position), the hugging member and the locking member have, when viewed from the side, together with an adjacent wall of the plug connector housing, an approximately S-shaped configuration. In this case, the hugging member converges with the locking member in an arc, preferably an arc of approximately 180 degrees (U-shaped), and the blocking member converges with a wall of the electrical plug connector in an arc, preferably, in the same way, an arc of approximately 180 degrees (U-shaped) ). Preferably, the respective articulation has been configured, in this case, as a film articulation and, in each case, is directly attached to an arc. In other words, the film joint of the blocking member is preferably itself a part of the blocking member, and the film articulation of the hugging member is itself a part of the hugging member.

In the case of an electrical plug connector according to the invention (in which the plug connector housing comprises at least one electrical contact element received therein and, preferably, a cable electrically connected thereto), the member Lock is coupled with at least one contact element. In this case, a protrusion of the blocking member preferably protrudes into an existing recess in the electrical contact element.

Preferably, the blocking member is disposed outside the plug connector housing, such that the protrusion of the blocking member partially protrudes, in the locked position, through an existing through recess in a chamber wall contact. This portion of the projection serves to engage with the electrical contact element. On the other hand, this preferably allows coupling of the locking member in the plug connector housing, such that an edge of the projection engages an edge of the through recess. In addition, additional locking and / or positional fixation of the locking member can be provided with the plug connector housing.

The hugging member according to the invention, which is preferably articulated in the locking member, has a device for hugging the cable. In this case, the hugging device has preferably been configured as a comb having at least one hugging groove. On the other hand, it is possible for the hugging member to interact, in the embraced position, with a portion of the plug connector housing and, therefore, to hug or secure the cable in the hugging member or in the plug connector housing .

In a preferred embodiment of the invention, the actual hugging device protrudes from the tongue of the hugging member substantially at right angles. In the embraced position, the protruding hugging device overlaps with a region intended for access to one or more contact chambers of the plug connector housing within which the electrical contact elements are received. This overlap according to the invention allows the hugging device to enter the region of the cables. In the embraced position, the hugging member is located, preferably at least in part, in a position directly adjacent to the locking member, which rests, preferably, resting on the plug connector housing. In this case, the hugging device overlaps with a portion of the locking member that is articulated with the plug connector housing.

In one embodiment of the invention, the hugging member is locked or secured, in the embraced position, preferably by the hugging device, to a portion of the plug connector housing. This allows the hugging member to be secured to the plug connector housing, thereby preventing the movements of the cables from propagating into the fixing element as a whole. The hugging member, which is preferably nested in its configuration, therefore ensures the cables to the plug connector housing, thereby preventing the movements of the cables from propagating into the electrical contact element. On the other hand, the hugging member can be secured to the plug connector housing and / or to the blocking member, for example, by blocking.

In preferred embodiments of the invention, the hugging device has at least one hugging groove within which a cable can be hugged. In this case, the hugging groove has been configured in such a way that it can reliably embrace the cable or the electrical insulation of the cable. This is achieved either as a result of the fact that the width of the groove has been configured to be slightly smaller than the diameter of the cable, either by a gradually narrowed groove into which the cable is inserted with a certain degree of force .

In a preferred embodiment of the invention, the embracing device has been configured in the manner of a comb with alternating grooves and embracing prongs, such that the prongs are preferably partially elastic. Elastic handles allow the effective hugging of a cable inside a groove.

On the other hand, it is possible to provide the projections of the spikes, which protrude inward in the direction of the groove, such that these projections, on the one hand, embrace the cable and, on the other hand, prevent the cable from Get out of the groove. On the other hand, locking recesses can be provided at the edges of the groove, that is, at the barbs, such that the recesses are provided in two directly adjacent barbs such that they accommodate, at least in part, a cable and therefore they hug the cable. On the other hand, another form of coupling can be used additionally, for example, by means of a sliding part arranged in the hugging device. In addition, it is possible to make the cable thinner in a region destined to be hugged in the hugging device, such that, on the one hand, the grooves or the barbs are adapted to this so that they continue to hug the cable ( see above) and, on the other hand, the thinning of the cable causes it to be embraced in the prongs in a direction perpendicular to these (direction in which the electrical contact elements are inserted during manufacturing).

Additional embodiments of the invention arise from the remaining dependent claims.

The invention will be described in what follows from this report based on embodiments provided by way of example and with reference to the accompanying drawings, in which:

The invention will be described in greater detail in what follows from this memory based on a plug connector housing 101 for a 4-pin electrical plug connector 100, and four electrical contact elements 10 in the form of female plug contacts which are received in the electrical plug connector 100. The electrical plug connector 100 according to the invention has been configured, in this case, such that it is suitable for the electrical connection of an airbag to a steering column or to a clock spring of a motor vehicle, or for the electric coupling of an airbag.

The invention should not, however, be limited to such embodiments, but instead refers, in a very broad sense, to plug connector or conjugate plug connector housings, or to electrical plug connectors or connectors. electric plug conjugates. It is therefore possible to provide, instead of female plug contacts, pin contacts in the plug connector housing 101 according to the invention. On the other hand, the number of electrical contact elements 10 within the plug connector housing 101 may vary. In addition, it is possible to omit a connector position securing member 300 on the conjugate plug connector 200, which will be described later in this specification with reference to Figures 4 to 7, of the plug pin connector 100. In principle, the invention can be applied to all cases in which the movement of a cable 30 with respect to the electrical contact elements 10 attached thereto must be kept at bay.

The drawings, see, in particular, Figures 1, 3 and 4, show an embodiment of a plug connector housing 101 according to the invention (see Figures 3 and 7). In this case, the electrical plug connector 100 comprises the plug connector housing 101 and at least one electrical contact element 10 that is received within it (see Figure 3), as well as, preferably, a cable 30 which It is electrically connected to the electrical contact element 10.

In the present embodiment of the invention, the electrical plug connector 100 has been configured as a 4-pin plug connector for an electric clock spring connection of an airbag. It is, however, possible to equip the electrical plug connector 100 with any desired number of electrical contact elements 10, with a further preferred embodiment of the invention being a 5-pin plug connector for the electrical coupling of an airbag.

The plug connector housing 101 has, on a longitudinal side thereof (with respect to a longitudinal axis L of the plug connector housing 101), a receptacle 130 for a connector position securing member 300. The connector position assurance member 300 serves to couple the electrical plug connector 100 into an electric connector plug conjugate 200 (see Figures 4 to 7).

On the other hand, the plug connector housing 101 has a collar 140 which, in conjunction with the electric conjugate plug connector 200, facilitates a secure fit of the electric plug connector 100 into the electric conjugate plug connector 200. For this purpose, collar 140 and a conjugate plug connector housing 201 (see Figure 4) have mutually corresponding projections and grooves, or similar elements. In the present example, collar 140 has been provided, as opposed to receptacle 130 for connector position securing member 300, on a longitudinal side of pin connector housing 101. In this case, the collar 140 extends upwardly from a lower face 103 of the

plug connector housing 101 up to approximately one third to one half of the total height of the

pin connector housing 101, and therefore runs at least 90 to 180 degrees around the

plug connector housing 101 (see Figure 2). In other embodiments of the invention, it is preferable

provide the collar 140 in such a way that it circumscribes, as far as possible, the entire plug connector housing 101. In other words, the collar 140 may, in this case, also extend around the receptacle 130 arranged laterally in the plug connector housing 101.

A fixing element 110 according to the invention can be arranged in the plug connector housing 101, which serves to fix the electrical contact element 10 which has been configured as a female plug contact and, at the same time, a cable 30 electrically connected to the electrical contact element 10. In other words, the fixing element 110 according to the invention allows, on the one hand, that the electrical contact element 10 be secured within the plug connector housing 101 and, on the other part, that the cable 30, which is connected to the electrical contact element 10, is secured to the plug connector housing 101.

Figures 1 to 3 show the fixing element 110 according to the invention in first and second open positions, while Figures 4 to 7 show the fixing element 110 according to the invention in a fixed position (locked position and embraced position; see below).

As shown in Figure 3, the fixing element 110 has been integrally configured, that is, materially in one piece with the plug connector housing 101. It is, however, possible to fabricate the fixing element 110 as an external part and then dispose of this external part correspondingly in the plug connector housing 101 to fix the electrical contact element 10 and the cable 30. In this way, it is, for example, possible to provide the fixing element 110 in such a way that it is capable of pivoting with respect to the pin connector housing 101, for example, by means of bearings.

In the present embodiment provided by way of example, the fixing element 110 is connected to the plug connector housing 101 by means of a first joint 112 that is preferably configured as a film joint. The first joint 112 mounts a locking member 114, configured as a locking tab belonging to the fixing element 110, in the plug connector housing 110. In this case, the bearings are preferably configured on an upper face 102 of the pin connector housing 101.

The locking member 114 of the fixing element 110 serves to engage the electrical contact element 10 within a contact chamber 150 of the plug connector housing 101 (see Figure 3). For this purpose, the blocking element 114 has a blocking lug 118 which can be coupled with an existing recess 18 in a blocking surface corresponding to it, in the electrical contact element 10. In other words, in the locked position of the blocking member 114 or of the fixing element 110, the locking lug 118 blocks the electrical contact element 10 inside the contact chamber 150 or inside the plug connector housing 110. In order to allow the locking lug 118 to be advanced to the recess 18 existing in the locking surface of the electrical contact element 10, a respective portion of the plug connector housing 101 has a through recess 158 in a region of a wall 152 of the contact chamber 150. Through the through recess 158, a free end portion of the locking lug 118 protrudes into the interior of the contact liner 150, thereby making it possible for the locking lug 118 it is coupled with the electric contact element 10 inside the contact chamber 150.

In this case, the blocking member 114 preferably has a tongue shape in its configuration, such that the locking lug 118 preferably extends along the entire width B (see Figure 1) of the blocking member 114 In this case, the locking lug 118 protrudes from a plane of the locking member 114 preferably in the manner of a hitch, such that the locking lug 118 is preferably located at a longitudinal end of the locking member 114 .

In order to prevent accidental sliding of the locking lug 118 out of the contact chamber 150 and, therefore, the decoupling of the electric contact element 10, the locking lug 118 has an edge 119

formed therein, which is locked with an edge 159 of the contact chamber 150. In this case, at least part of the edge 159 has been configured as an inner portion of the wall 152 (see Figures 3 and 5) of the chamber of contact 150. In other words, according to the invention, the locking lug 118 is coupled with the contact chamber wall 152 belonging to the contact chamber 150, and, therefore, at the same time, is also coupled with the electrical contact element 10 existing within the plug connector housing 101. On the other hand, the edge 159 continues inside the plug connector housing 101, between the contact chambers 150 that are adjacent between their

The blocking member 114 may have a projection 116 which, preferably, extends over the entire width B (see Figure 1) of the blocking member 114 and can be coupled with an existing recess 106 on a blocking surface corresponding thereto. , in the plug connector housing 101. Obviously, the reverse situation is also possible in which the projection 116 is arranged in the plug connector housing 101 and the recess 106 is disposed within the blocking member 114. In this case, the projection 116 and the recess 106 serve to placing the blocking member 114 in such a way that this rotation is prevented in the locked position and is secured to the plug connector housing 101 at least in the longitudinal direction L. In this case, the projection 116 and an edge of the recess 106 can be coupled to each other.

On the other hand, the fixing element 110 according to the invention has, in addition to the blocking member 114, an embracing member 122. In this case, the embracing member 122 according to the invention is capable of pivoting with respect to the blocking member 122 and has been configured as a hugging tongue. This occurs, preferably, by means of a second joint 120 which, in the same way, has preferably been configured as a film joint. It is, however, also possible to configure the hugging member 122 independently of the blocking member 114, as well as providing the hugging member 122 in the blocking member 114 in such a way, that it can pivot through the bearings.

Preferably, the mounting of the hugging member 122 on the blocking member 114 is provided on one side of the blocking member 114 which is opposite to the locking lug 118. This can be carried out at any desired portion of the surface of the locking member 114 that is opposite the locking lug 118. Preferably, the cramming member 122 is, however, linked to one of the ends of the locking member 114, the locking lug 118 having been provided on an opposite side (with respect to a cross-section shown in Figure 3) of the blocking member 114. In this case, the hugging member 122 is attached to the end of the blocking member 114, preferably materially in one piece through a portion U-shaped. The second joint 120 forms part of this U-shaped portion. The hugging member 122 joins the second joint 120. At one end of the hugging member No. 122, opposite the second joint 120, the hugging member 122 has a hugging device 126.

In the embodiment illustrated in the drawings of the invention, the hugging member 122 forms a free end portion, and the blocking member 114, a delimiting end portion of the fixing element 110, although it is also possible to reverse this. In this case, the hugging member 122 is preferably joined in one piece, preferably to the connector connector housing 101 by means of the first joint 112; and the blocking member 114, which then acts as a free end portion of the fixing element 110, is joined again to the hugging member 122 again, preferably, materially in one piece by means of the second joint 120.

The clamping device 126 according to the invention makes it possible for the cable 30 (see Figure 7) of the electrical contact elements 10 to be secured to the plug connector housing 101, as a result of which the movements of the cables 30 without intercepts and can no longer propagate inside the electrical contact element 10. In this case, the forces from the cable 30 are guided inside the plug connector housing 101 through the clamping device 126, and into the interior of the plug connector housing 101 through the clamp member 122 and the lock member 114. For the first case, the clamp device 126 is directly blocked with the plug connector housing 101 by a projection 109 located in the housing 101 of plug connector and a projection 129 located in the hugging device 126, and for the latter case, the forces are guided inside of the plug connector housing 101 through the projection 116 of the blocking member 114 and through a delimitation of the locking surface 106 of the connector connector housing 101.

The hugging device 126 has been configured in such a way that it ensures the cable 30. This can be carried out, for example, by the hugging of the cable 30 by the hugging device 126 and a corresponding portion located in the housing 101 of plug connector. It is also possible to configure the hugging device 126 in the manner of a comb that has some spikes 128 and grooves 127, such that the cables 30 can be embraced within the grooves 127.

In this case, each of the grooves 127 has been configured such that the cable 30 or the insulation of the cable 30 can be reliably embraced within the groove 127. For this purpose, the width of the groove 127 is, for example, slightly smaller than the outer diameter of the cable 30. On the other hand, it is possible to configure the groove 127 with a V-shape and, therefore, to hug the cable 30 closely inside it

by inserting it into the groove 127. On the other hand, projections (not shown) may have been provided laterally at the handles 128, after which the cable 30 can be hugged. This can be carried out, for example, also by means of recesses (not shown) arranged in the puzzles 128. In case the projections (not shown) or recesses (not shown) are present in the puas 128, the projections (not shown) or the recesses (not shown) are directly opposite to each other according to a transverse direction of the connector connector housing 101 (the groove width direction 127).

The hugging device 126 of the hugging member 122 preferably protrudes at an angle of approximately 90 degrees from one of the ends of the tongue of the hugging member 122 and overlaps, in the embraced position (see Figures 4 to 7), with a mount of the locking member 114 in the plug connector housing 101. On the other hand, in the embraced position and in the locked position of the fixing element 110, the hugging member 122 rests directly supported on the blocking member 114, which, in turn, rests directly supported on the connector housing 101 of plug. According to the invention, both the blocking member 114 and the hugging member 122 are in this case, each of them, configured as folding covers that can be folded together, on the one hand, one on top of the other and, on the other hand, in the connector connector housing 101.

In the open position of the locking member 114 and the hugging member 122, which can be seen in the clearest form in Figures 1 and 3, the hugging device 126, the hugging member 122, the second joint 120, the Locking member 114, the first joint 112 and a portion of the plug connector housing 101 that joins the first joint 112, have, in cross section, along the longitudinal axis L of the plug connector housing 101 (see Figure 3), approximately the shape of an S. As a result of the zigzag configuration of the fixing element 110, a single grip allows both the electrical contact element 10 to be locked inside the plug connector housing 101, as, at the same time, the cable 30 is hugged tightly in the connector connector housing 101. In this case, only force is exerted on one of the ends of the blocking member 114 and on one of the ends of the hugging member 122. For simple handling of the hugging member 122, the hugging member 122 may have a device drive 124 in the form of a hitch protruding therefrom, such that the drive device 124 can serve as a stopper of the plug connector housing 101, disposed in the conjugate plug connector housing 201 (see Figure 7).

In the embraced position of the hugging member 122 and, therefore, preferably also in the locked position of the blocking member 114, the hugging device 126 is preferably locked on the upper face 102 of the plug connector housing 101. This is preferably carried out through the projection 129, which is preferably configured integrally in the hugging device 126 and can come to rest resting on one shoulder or on the projection 109 of the connector connector housing 101 pin, and therefore secures the clamp device 126 in addition to the pin connector housing 101. Through this union, which is preferably configured as a clamp, the forces from the movements of the cables 30 are guided directly into the housing 101 of the plug connector. The protrusion 109 and the protrusion 129, which interact in securing the clamping device 126 to the plug connector housing 101, can be clearly seen in Figure 2, in a position not mutually locked.

On the other hand, the plug connector housing 101 may have, on the upper face 102, projections 108 that have been configured as teeth, such that a longitudinal end or a longitudinal end portion of the pin 128 may be arranged between two of the projections 108 that are directly adjacent to each other (see, in particular, Figures 1 and 4). The projections 108 can, in this case, perform the task of placing the handles 128 and also of embracing the handles 128. In other words, the projections 108 that are directly adjacent to each other, are arranged separated from each other a distance such that Pua 128 can be hugged inside. In this case, mutually corresponding locking projections or locking recesses can be provided again on the pin 128 or on the projections 108. This guarantees an effective introduction of the force from the movements of the cable, through the handles 128 , inside the projections 108 and, therefore, inside the connector connector housing 101.

The connection of the electric plug connector 100 in accordance with the invention to the electric plug connector 200 will be described in greater detail in what follows from this memory with reference to Figures 4 to 7. In this case, the electric connector 100 of The plug has four female plug contacts (not shown) received inside, and the cable 30 (see Figure 7), which is electrically connected to the electrical contact element 10 formed as a female plug contact. The cable 30 is, in this case, mechanically connected by means of an insulation flange 12 (see Figure 3), and electrically, for example, by welding, welding with interposed material or drawing, to an electrical contact region 14 ( see Figure 3) of the electrical contact element 10. In this case, the fixing element 110, which has been constructed of the blocking member 114 and the hugging member 122, is both in the locked position and in the embraced position. As a result, the electrical contact elements 10 are locked inside the plug connector housing 101 by means of the blocking member 114, and the cables 30 are secured to the plug connector housing 101 by the clamping member 122, which it is pivoted by the first joint 112.

The housing of the conjugate plug connector 201 of the electric conjugate plug connector 200 corresponds, in its construction, with the plug connector housing 101 of the electric plug connector 100 and with the electric conjugate plug connector 200, which together form a electrical plug connection 1 according to the invention. The conjugate plug connector housing 201 may, in the same way, have a fixing element 110 according to the invention. Electrical contact elements 20 configured as pin contacts (see Figures 5 to 7) are received inside the conjugate plug connector housing 201 in a manner corresponding to the electrical contact elements 10 of the electrical plug connector 100.

Figure 4 shows a starting position in which the electric plug connector 100 is moved towards the electric conjugate plug connector 200. In this case, the connector position securing member 300 is received in a position prior to blocking, inside receptacle 130 or partially inserted inside (see also Figures 5 and 6). It is, however, also possible to place the connector position assurance member 300 into the receptacle 130 only once the electrical plug connector 100 has been attached to the electrical conjugate plug connector 200.

Figure 5 shows the electrical plug connector 100, which is partially fixed to the electrical connector plug conjugate 200 in such a way that the electrical contact elements 10, 20 are not yet in mechanical contact with each other. 5 clearly shows the blocking of the locking lug 118 within the contact chamber 150. In this case, the edges 119, 159 of the locking lug 118 and the through recess 158 or wall 152 of the contact chamber butt contact between sf

Figure 6 shows the electric plug connector 100 in a position prior to blocking, in the electric plug connector 200 (the connector position securing member 300 is, in this case, in the same way, even in its position prior to blocking), such that the electrical contact elements 20 may already be in electrical contact with the electrical contact elements 10. In this case, a hitch 160, which is arranged so as to be laterally movable within the receptacle 130, belonging to receptacle 130 or to the plug connector housing 101, rests supported by a projection 260 of the conjugate plug connector housing 201. The hitch 160 is preferably elastic in its configuration and, as shown in Figures 5 to 7, in its resting position. On the other hand, a securing projection 362 of an securing tongue 360 of the connector position assurance member 300 rests supported on the hitch 160, in the position prior to blocking.

The main purpose of the connector position assurance member 300, when inserted and locked, is to ensure that the electrical plug connector 100 and the conjugate plug electrical connector 200 are mutually locked correctly, since only in this case is it it is possible to bring the connector position assurance member 300 out of its position prior to blocking (see Figures 5 and 6), to its locked final position (see Figure 7). In the position prior to blocking, the securing tabs 360, preferably with the securing boss 362, and the hitch 160 are mutually locked in such a way that this lock can only be released if the electrical plug connector 100 is in the correct plug position, in the electric conjugate plug connector 200, and can lead to the complete insertion of the connector position assurance member into the receptacle 130; the locked position of the connector position assurance member 300 within the receptacle 130 being established by mutually complementary surfaces 262, 162 of the projection 260 and the hitch 160. In the position prior to blocking, on the other hand, the securing projection 362 and the hitch 160 butt contact each other on mutually corresponding securing surfaces 363, 163, and lock each other in the direction in which the connector position securing member 300 is inserted into the receptacle 130.

The securing projection 362 has been configured in a free longitudinal end portion of an securing tongue 360 of the connector position assurance member 300, and prevents, in the other, in the plug position, shown in Figure 7, of the electric plug connector 100 on the electric plug-in connector 200, that the hitch 160, and, therefore, also the plug connector housing 101, move to the open position where the electric plug connector 100 could get rid of the electric plug connector 200 conjugate.

During the connection of the electrical plug connector 100 to the electrical connector of the conjugate plug 200 (transition from Figure 6 to Figure 7), the coupling 160 of the plug connector housing 101 slides, firstly, along the complementary surface 262 of the projection 260 existing in the conjugate plug connector housing 201, completely exceeds the projection 260 and (see below, with reference to Figures 6 and 7) returns to its resting position. The securing projection 362 of the securing tongue 360 and, also, a longitudinal end portion of the securing tongue 360 also jointly carry out this movement. Only once the projection 260 has passed, is it possible for the securing projection 362 to slide on the complementary surface 162 of the hitch 160. The projection 260 and the elastic jump backwards of the hitch 160 after the projection 260 raise the securing surface 363 over the hitch 160, whereby the securing surface 363 is allowed to slide over the complementary surface 162 of the hitch 160; This is facilitated by the fact that the hitch 160 and the projection 260 are substantially at the same height on a 'common' surface or at a joint between the two.

Once the hitch 160 has been exceeded, the securing boss 362 is adjusted by elastic jump after (see below with reference to Figure 7) the hitch 160, to its locked position.

In this position, the connector position assurance member 300 is in its final position locked within the receptacle 130, and the electrical plug connector 100 can no longer detach from the electrical conjugate plug connector 200. In this position, the member Connector position assurance 300 is blocked, for example, by a locking lug 332, on a shoulder 132 disposed in / inside receptacle 130. In the position prior to blocking, the connector position assurance member 300 is locked , preferably by means of locking hooks 310 shown in Figure 1, inside receptacle 130. As a result of these two locks (332, 132; 310, 130) of connector position assurance member 300 within receptacle 130, the connector position assurance member 300 is, on the one hand, protected, in its position prior to blocking, from falling out of receptacle 130, and, by or tra part, coupled in its locked position.

In order to facilitate the insertion or removal of the connector position securing member 300 into or out of the receptacle 130 of the plug connector housing 101, arcs 312, which have been integrally configured with the locking hooks 310 (see Figure 1), are not attached to the securing tab 360 but instead have been arranged separately from it; that is, the tongue 360 is movable with respect to the locking hooks 310. If the tongue is then raised, it leaves a coupling position with the arches 312, which can now be moved towards each other, whereby allows the release of the coupling of the connector position assurance member 300 within the receptacle 130.

The connector position assurance member 300 further hinders the detachment of the electrical plug connector 100 from the electrical conjugate plug connector 200. If it is desirable to do this, the connector position assurance member 300 is moved back to the position shown in Figures 4 to 6. First, in this case, the coupling of the connector position securing member 300 with the receptacle 130 is decoupled, such that, subsequently, the securing projection 362 of the securing tongue 360 is moved away by means of the hitch 160 of the plug connector housing 101. In this case, the mechanical contact of the securing boss 362 and the hitch 160 has preferably been configured not as an authentic locking joint, but instead as a butt contact of two oblique surfaces (configured in the longitudinal direction L of the electrical plug connection 1). Subsequently, in the position prior to locking of the connector position securing member 300, the locking hook 310 is reattached with a projection (not shown) or with a contact surface of a recess (not shown) located at / inside receptacle 130. Subsequently, hitch 160 is disengaged from projection 260 of conjugate plug connector housing 210. Preferably, connector position securing member 300 is not removed from receptacle 130 but instead instead , remains in its position prior to blocking (4.5 mm).

A lateral pressure (perpendicular to the longitudinal axis L of the electrical plug connection 1) acting in the plug connector housing 101 and / or in the receptacle 130 and / or in a portion of the connector position assurance member 300 which protrudes from receptacle 130, allows the coupling between the hitch 160 and the projection 260 to be released and that the electrical plug connector 100 is therefore detached from the electrical connector of the conjugate plug 200. For this purpose, the hitch 160 is attached , preferably materially in one piece, to the plug connector housing 101 and / or to the receptacle 130 by at least one torsion bar (not shown). As a result of the lateral pressure, the hitch 160 and the free end portion of the securing tongue 360 (securing projection 362) are moved away by means of, preferably, two torsion bars, through the projection 260 of the connector electric plug conjugate 200.

The invention has a large number of blocking elements or blocking surfaces (18, 106, 108, 109, 116, 118, 119, 129, 132, 158, 159, 160, 163, 260, 310, 332, 362) that interact with blocking elements or corresponding blocking surfaces (118, 116, 128, 129, 106, 18, 159, 109, 332, 118, 119, 260, 363, 160, 130, 132, 160), thereby a retention, locked position, hugged position, coupling according to the invention, and other similar concepts are configured or established. Obviously, it is possible to use blocking elements or blocking surfaces (18, 106, 108, 109, 116, 118, 119, 129, 132, 158, 159, 160, 163, 260, 310, 332, 362, 363), or combinations of blocking elements or blocking member, or blocking surfaces (18/118, 106/116, 108/128, 109/129, 109/108/128, 110/101, 114/101, 119 / 159, 122/101, 126/30, 127/30, 128/30, 132/332, 158/118, 160/260, 160/362, 163/363, 300/130, 300/101, 300/201, 310/130, 332/132, 360/130, 360/312, 360/310) different from those respectively applied. In particular, it is possible to kinematically invert the respective lock. In other words, for example, starting from a blocking projection, to a blocking recess, and, accordingly, starting from a blocking recess, to a blocking projection, or to the shoulders that can be locked together, They turn around or invest.

Embodiments of the invention are also possible with or without the connector position assurance member 300, it being preferable in this last embodiment that the plug connector housing 101 does not have the receptacle 130 and, preferably, in addition, that the collar 140 substantially circumscribe the entire plug connector housing 101.
