Description

[0001] The invention relates to a connector, in particular a push-pull connector, and a use of a connector.

[0002] Connectors are designed to accommodate a plug connected to a cable and to be connected to a connector socket. The connector socket has a plug socket that matches the plug, so that by connecting the connector to the connector socket, the plug can be electrically connected to the socket. Push-pull connectors are also known for enabling particularly easy connection and disconnection of the connector from the connector socket.

[0003] To ensure a secure (electrical) connection between the plug and the socket, it is necessary to protect the connector or the connector connected to the socket from moisture and dirt. Furthermore, the assembly of a connector should be as simple and quick as possible.

[0004] Furthermore, DE 43 07 350 C1 discloses an arrangement for clamping a cable to a proximity switch, which has a cylindrical socket in which the base of a conductor connection part is rigidly arranged and which has an external thread. To simplify handling, an inner sleeve enclosing the cable is provided, which, with a forked end, encloses the conductor connection part designed as a terminal block. Furthermore, an outer sleeve is provided that can be screwed onto the socket, by means of which the inner sleeve can be axially tightened against the front end of the socket.

[0005] US 2003 / 085575 A1 describes a device for axially retaining a cylindrical element, in particular a cable, comprising a sleeve with an external thread, which is extended in the axial direction by clamping plates, and an overlapping nut having an internal pressure surface. The nut is designed to act radially on the clamping plates of the bushing in the direction of the cylindrical element, which has been previously inserted into the sleeve. The device also comprises a sleeve, which is also provided with clamping plates and whose outer diameter is no larger than the inner diameter of the sleeve. The clamping plates are also designed to act on the cylindrical element.

[0006] US 5,167,527 A relates to an electrical plug assembly with internal, adjustable gripping means and sealing means for electrical cables of various sizes. The internal, adjustable gripping means is a three-jaw gripping assembly with pie-shaped jaws slidably mounted on rails that move toward and away from the center of the plug body to form a gripping circle around cables of various sizes. The cable seal consists of a notched rubber bushing sandwiched between two rings. When the cover is tightened, the rings on either side of the rubber bushing are compressed, causing the bushing to collapse and seal the cables.

[0007] Furthermore, US 2006 / 0040553 A1 relates to a waterproof connector with a one-piece rubber plug.

[0008] It is therefore an object of the present invention to provide a connector which has good sealing properties and is easy to assemble.

[0009] This object is achieved by the subject matter of the independent claims. Preferred embodiments are defined in the dependent claims.

[0010] One aspect relates to a connector, in particular a push-pull connector, for receiving a plug connected to a cable and for connecting to a connector socket, comprising: a first housing element, which is designed to surround the cable and the plug at least partially along a plug-in direction of the plug-in connector into the plug-in connector socket; a sealing element arranged within the first housing element, which is designed to surround the cable at least partially along the plug-in direction; and a securing means connectable to the first housing element, which is designed to surround the cable at least partially along the plug-in direction and which is insertable into the first housing element at least partially along the plug-in direction, wherein by connecting the securing means to the first housing element, the securing means acts on a first contacting surface of the sealing element such that an outer side of a first sealing portion of the sealing element contacts the inner side of the first housing element and an inner side of the first sealing portion contacts the cable sheath of the cable.

[0011] Advantageously, connecting the securing means to the first housing element allows the sealing element to seal against the cable or cable sheath and simultaneously seals the sealing element against the first housing element, thereby reliably preventing moisture and dirt from penetrating the connector. Furthermore, the connector socket can have a plug socket, which can be connected to the plug by connecting the connector to the connector socket.

[0012] For the purposes of this disclosure, the term "insertion direction" refers to the direction in which the connector is inserted into the connector socket for proper connection. The insertion direction also corresponds to the direction in which the plug is inserted for connection to the connector socket. Furthermore, the insertion direction is parallel to the longitudinal axis of the connector.

[0013] Preferably, the first housing element can be designed to surround a connector of a specific connector type, for example an RJ45, USB, or coaxial connector, at least in sections along the insertion direction.

[0014] The first housing element can be designed, in particular, as an inner housing element of the connector, which is surrounded by a second housing element at least in sections along the insertion direction. The second housing element can be designed as an outer housing element of the connector. Furthermore, the second housing element can be designed to be movable relative to the first housing element along the insertion direction.

[0015] Furthermore, the connector can have at least one connector-side locking element, with which the connector can be locked to the connector socket in order to assume a locked state. In the locked state, the at least one connector-side locking element is particularly designed to be locked to a corresponding connector socket-side locking element. Furthermore, the at least one connector-side locking element can be arranged on an outer side of the first housing element and / or can be fastened and / or fastened to the outer side of the first housing element.Furthermore, the plug connector can be designed such that, by a relative movement of the second housing element with respect to the first housing element along the insertion direction, the at least one plug-connector-side locking element can be locked to the plug-connector-socket-side locking element and / or the at least one plug-connector-side locking element can be released from the plug-connector-socket-side locking element.

[0016] To seal the plug connector, in particular to seal the first housing element from the cable, the plug connector, as described above, has a sealing element arranged within the first housing element. The sealing element can extend at least partially along the insertion direction, wherein the first sealing section relates to a section of the sealing element which is arranged at an end of the sealing element opposite the insertion direction. The outer side of the first sealing section refers to an outer side of the sealing element, which faces substantially in the direction of the first housing element. Furthermore, the inner side of the first sealing section relates to an inner side of the first sealing element, which faces substantially in the direction of the accommodated cable and / or cable sheath.

[0017] Furthermore, the first housing element can have a first access opening and a second access opening, which are arranged opposite one another and spaced apart from one another. The first access opening and the second access opening of the first housing element extend substantially perpendicular to the insertion direction and / or longitudinal axis of the plug connector. Furthermore, the first access opening and the second access opening can be connected to one another by a wall of the first housing element. The first access opening, the second access opening and the wall of the first housing element can further form a receiving space in which the first sealing element is arranged. Furthermore, the receiving space can accommodate the cable and the plug connected to the cable, at least in sections, along the insertion direction. In other words, the cable and the plug can be arranged at least in sections in the receiving space.The wall can extend in particular along the insertion direction or surround the longitudinal axis of the connector in sections.

[0018] Furthermore, the first housing element can have a substantially hollow cylindrical section, the cylinder axis of which is parallel to the longitudinal axis of the connector and whose cylinder axis lies, in particular, on the longitudinal axis of the connector. Furthermore, the sealing element can be arranged in the hollow cylindrical section.

[0019] By connecting the securing means to the first housing element, the securing means can be moved relative to the first housing element in the insertion direction. In particular, the securing means can be screwed to the first housing element and / or screwed into the first housing element in the insertion direction. In particular, by screwing and / or turning the securing means into the first housing element, the force acting on the first contact surface of the sealing element can be increased, whereby the outer side of the first sealing section seals particularly well relative to the first housing element and the inner side of the first sealing section seals particularly well relative to the cable and / or cable sheath, or is pressed against them.

[0020] The plug connector can preferably have a further sealing element which is designed to seal the first housing element from the plug connector socket when connected. In particular, the further sealing element can be arranged on an outer side of the first housing element and surround the outer side at least in sections along the insertion direction. When the plug connector and plug connector socket are connected, the further sealing element thus enables the first housing element to be sealed from the plug connector socket. The further sealing element preferably has at least one sealing lip which surrounds the first housing element and seals the first housing element from the plug connector socket when the plug connector and plug connector socket are connected. The further sealing element preferably has at least two, and particularly preferably three, sealing lips.Furthermore, the further sealing element can be arranged at an end of the first housing element lying in the insertion direction.

[0021] The sealing element and / or the further sealing element can preferably be made of an elastic material such as rubber and / or caoutchouc in order to ensure the highest possible deformability and / or adaptability to the first housing element, the cable, the cable sheath and / or the connector socket, thereby advantageously influencing the sealing effect.

[0022] Advantageously, the plug connector can have a stop element arranged within the first housing element, which is designed to surround the cable and / or the plug at least in sections along the insertion direction, wherein by connecting the securing means to the first housing element, the stop element acts on a second contacting surface of the sealing element in such a way that an outer side of a second sealing section contacts the inside of the first housing element, and wherein preferably an inner side of the second sealing section contacts or does not contact the cable sheath.

[0023] Advantageously, the provision of the stop element enables the sealing element to be moved in the direction of the stop element by connecting the securing means to the first housing element, and in particular to be squeezed between the securing means and the stop element. In particular, the securing means, the sealing element, and the stop element can be arranged one after the other in this order in the insertion direction within the first housing element. The second sealing section of the sealing element can be arranged at an end of the sealing element lying in the insertion direction. Furthermore, the outer side of the second sealing section relates to the outer side of the sealing element, and the inner side of the second sealing section relates to the inner side of the sealing element.

[0024] When using the connector, it can be provided that the cable is used stripped in the area of ​​the stop element, i.e. that the cable sheath is removed in the area of ​​the stop element, whereby the inner side of the second sealing section does not contact the cable or the cable sheath. By using it accordingly, it is advantageously possible to enlarge the area of ​​the cable that is free of cable sheath in order to expose as much of the cable shielding as possible, which makes it easier to connect the shielding to the plug. Furthermore, the first sealing section and the outer side of the second sealing section adequately seal the connector.

[0025] The plug connector can preferably be designed to prevent displacement of the stop element within the first housing element in the insertion direction beyond an arrangement position. Advantageously, this can prevent displacement of the stop element in the direction of insertion when the sealing element is pressed onto the stop element by the securing means. The sealing element can therefore be squeezed particularly well between the stop element and the securing means in order to seal the plug connector well. In particular, the first housing element can taper on the inside to prevent displacement of the stop element in the insertion direction. For example, the first housing element can have an internal shoulder or projection against which the stop element rests and which prevents displacement of the stop element in the insertion direction.

[0026] Preferably, by inserting the securing means into the first housing element, the sealing element can be squeezed between the stop element and the securing means. This can advantageously increase the sealing effect.

[0027] Preferably, the sealing element can be configured to be substantially rotationally symmetrical. Furthermore, the rotational axis of the sealing element can substantially correspond to the longitudinal axis of the sealing element or the longitudinal axis of the first housing element. The rotationally symmetrical design offers the advantage that the orientation of the sealing element does not need to be taken into account during assembly of the connector. This prevents incorrect insertion of the sealing element into the first housing element, which could cause a leak in the connector.

[0028] Preferably, the outer side and the inner side of the sealing element can be arranged substantially opposite one another, and preferably the inner side is longer than the outer side. Furthermore, the outer side of the sealing element can face the inner side of the first housing element, and the inner side of the sealing element can face the longitudinal axis of the connector. Furthermore, the outer side and the inner side of the sealing element can run substantially parallel to one another.

[0029] Furthermore, the first contact surface of the sealing element faces substantially opposite to the insertion direction. Preferably, the sealing element can be configured as a substantially hollow cylinder, with the second contact surface facing substantially in the insertion direction. The first contact surface can also be regarded as the first end face of the sealing element, which faces substantially opposite to the insertion direction. Furthermore, the second contact surface can be regarded as the second end face of the sealing element, which faces substantially in the insertion direction.

[0030] In addition, the first contact surface has a first circumferential recess, and the securing means has a tapered end located in the insertion direction, which can be inserted into the first circumferential recess by connecting the securing means to the first housing element. Advantageously, the circumferential recess allows the securing means to be pressed into the recess when the securing means is connected to the first housing element, thus allowing the outer side of the first sealing section and the inner side of the first sealing section to be pressed particularly well against the inside of the first housing element or the cable.

[0031] In particular, the circumferential recess can extend into the sealing element in the insertion direction and be formed in a groove-like and / or groove-shaped manner on the first contacting surface. The circumferential recess of the first contacting surface can furthermore have an outer contacting section which is inclined with respect to the longitudinal axis of the plug connector, wherein the outer contacting section points in the direction of the longitudinal axis of the plug connector. Furthermore, the outer contacting section can merge into an inner contacting section of the first contacting surface, wherein the inner contacting section is inclined with respect to the longitudinal axis of the plug connector and points away from the longitudinal axis. Accordingly, the groove-shaped recess can be formed as a substantially circumferential wedge-shaped recess in the first contacting surface.Furthermore, the outer side of the sealing element and the inner side of the sealing element can be connected to one another by the first contacting surface and in particular by the outer and inner contacting sections.

[0032] Furthermore, the securing means can be substantially hollow-cylindrical, with the end facing the insertion direction being frustoconical. Thus, it is advantageously possible for the securing means to press into the recess with the frustoconical end when connecting the securing means to the first housing element, whereby the outer side in the region of the first sealing section and the inner side in the region of the first sealing section can be pressed particularly well against the first housing element or the cable sheath.

[0033] Furthermore, due to the frustoconical and hollow cylindrical design, the securing means can have a wall which is tapered at an end lying in the insertion direction. In other words, the wall thickness of the wall decreases at the end lying in the insertion direction as it runs in the insertion direction. Furthermore, the wall can have an outer circumferential wall section at the end lying in the insertion direction, which is inclined with respect to the longitudinal axis of the plug-in connector and points away from it. Furthermore, the outer wall section points substantially in the direction of insertion. Furthermore, the wall can have an inner circumferential wall section at the end lying in the insertion direction, which is inclined with respect to the longitudinal axis and points in the direction of the longitudinal axis. Furthermore, the inner wall section points substantially in the direction of insertion.The outer wall section and the inner wall section can in particular be arranged opposite one another.

[0034] Advantageously, it is thus possible for the outer wall portion of the securing means to contact and act upon the outer contacting portion of the sealing element when connecting the securing means to the first housing element, so that the outer side of the first sealing portion is pressed against the first housing element. Furthermore, the inner wall portion of the securing means presses against the inner contacting portion, so that the inner side of the first sealing portion is pressed against the cable or cable sheath.

[0035] Advantageously, the inclination of the outer wall section relative to the longitudinal axis of the connector can be greater than or equal to, preferably greater than, the inclination of the outer contacting section relative to the longitudinal axis of the connector. Accordingly, the outer side of the first sealing section can be better pressed against the first housing element.

[0036] Advantageously, the inclination of the inner wall section relative to the longitudinal axis of the connector can be greater than or equal to, preferably greater than, the inclination of the inner contacting section relative to the longitudinal axis of the connector. Accordingly, the inner side of the first sealing section can be better pressed against the cable or cable sheath.

[0037] Advantageously, the wall of the securing means is blunted at the end in the insertion direction to prevent damage to the sealing element. In particular, the securing means can have an end wall section at the end in the insertion direction, which extends substantially perpendicular to the longitudinal axis of the connector or perpendicular to the insertion direction. Furthermore, the end wall section connects the outer wall section to the inner wall section.

[0038] Preferably, the second contact surface can have a second circumferential recess, and the stop element can have a tapered end opposite the insertion direction, which can be inserted into the second circumferential recess by connecting the securing means to the first housing element. Advantageously, the second circumferential recess enables the stop element to be pressed into the second recess when the securing means is connected to the first housing element, thus forcing the outer side of the second sealing portion against the first housing element. Furthermore, the inner side of the second sealing portion can be pressed particularly well against the cable or cable sheath.

[0039] In particular, the second circumferential recess can extend into the sealing element opposite to the insertion direction and be formed in a groove-like and / or groove-shaped manner on the second contacting surface. The circumferential recess of the second contacting surface can furthermore have an outer contacting section which is inclined with respect to the longitudinal axis of the plug connector, wherein the outer contacting section points substantially in the direction of the longitudinal axis of the plug connector. Furthermore, the outer contacting section can merge into an inner contacting section of the second contacting surface, wherein the inner contacting section is inclined with respect to the longitudinal axis and points away from the longitudinal axis. Accordingly, the groove-shaped recess can be formed as a substantially circumferential wedge-shaped recess in the second contacting surface.Furthermore, the outer side of the sealing element and the inner side of the sealing element can be connected to one another by the second contacting surface and in particular by the outer and inner contacting sections.

[0040] Furthermore, the stop element can have a substantially hollow cylindrical section which extends at least partially along the longitudinal axis of the plug connector or along the insertion direction. The hollow cylindrical section can also have the tapered end of the stop element. In other words, the wall thickness of the wall of the stop element decreases at the end opposite to the insertion direction in the opposite direction. In particular, the tapered end can be rounded in the outer region and have a rounded outer wall section. Furthermore, the wall of the stop element can have an inner circumferential wall section at the end opposite to the insertion direction, which is inclined with respect to the longitudinal axis and points in the direction of the longitudinal axis. Furthermore, the inner wall section points essentially opposite to the insertion direction.

[0041] Advantageously, it is thus possible for the rounded outer wall section of the stop element to contact and act upon the outer contacting section of the sealing element when connecting the securing means to the first housing element, so that the outer side of the second sealing section is pressed against the first housing element. Furthermore, the inner wall section of the stop element can press against the inner contacting section, so that the inner side of the second sealing section is pressed against the cable or cable sheath.

[0042] Advantageously, the inclination of the inner wall section relative to the longitudinal axis of the connector can be greater than or equal to, preferably greater than, the inclination of the inner contacting section relative to the longitudinal axis of the connector. Accordingly, the inner side of the second sealing section can be better pressed against the first housing element.

[0043] Advantageously, the wall of the stop element is blunted at the end opposite the insertion direction to prevent damage to the sealing element. In particular, the stop element can have an end wall section at the end opposite the insertion direction, which extends substantially perpendicular to the longitudinal axis of the connector or perpendicular to the insertion direction. Furthermore, the end wall section connects the rounded outer wall section to the inner wall section of the stop element.

[0044] Preferably, the securing means is configured such that the securing means and / or the stop element do not contact the cable and / or the cable sheath. In particular, the securing means and the stop element, in particular the hollow cylindrical portion of the stop element, can each have an inner diameter that is larger than the outer diameter of the cable, so that the cable can be spaced apart from the stop element, in particular from the hollow cylindrical portion of the stop element, and from the securing means. This advantageously makes it possible to simplify the assembly of the connector, since the cable can be inserted more easily into the stop element and the securing means.

[0045] Preferably, the stop element can be configured to space the plug from the sealing element. In particular, the stop element can have a spacer section extending from the hollow cylindrical section of the stop element in the insertion direction. The spacer section allows the distance between the plug and the sealing element to be increased along the insertion direction, thus allowing for increased installation space, for example, to accommodate the connection of the cable shielding to the plug shielding.

[0046] Preferably, the connector can be designed such that the plug connected to the cable is replaceable. In particular, the first housing element can be designed such that the plug connected to the cable is replaceable. The first housing element can, in particular, be designed to accommodate the plug at least in sections. The replaceability of the plug ensures the reusability of the connector.

[0047] A further aspect relates to the use of a previously described connector, in particular a push-pull connector, comprising: Receiving a connector connected to a cable in the first housing element; inserting the sealing element into the first housing element; and connecting the securing means to the first housing element.

[0048] Furthermore, the use may provide that, before inserting the sealing element, a stop element as described above is inserted into the first housing element.

[0049] In the context of the present disclosure, the longitudinal axis of the connector, the longitudinal axis of the first housing element and the rotational axis of the sealing element lie on one another. Figure description

[0050] A preferred embodiment of the invention is explained below by way of example with reference to the accompanying figures. In the figures: Figure 1 shows a perspective view of a connector. Figure 2 shows a cross-sectional view of the connector along the longitudinal axis of the connector. Figure 3 shows a detailed cross-sectional view of the connector along the longitudinal axis of the connector.

[0051] Figures 1 and 2show a connector 10, which at least partially surrounds a plug 12 arranged in the connector 10 and at least partially surrounds a cable 14 connected to the plug 12. The connector 10 is designed to be locked to a connector socket (not shown). To lock the plug connector 10 to the connector socket, the connector 10 is moved or pushed onto the connector socket in an insertion direction E. The insertion direction E is substantially parallel to a longitudinal axis L of the connector 10. Furthermore, the longitudinal axis L of the connector lies on the longitudinal axis of the cable received in the connector 10. Furthermore, the connector 10 has a first housing element 16, which is arranged internally in the connector 10. The first housing element 18 surrounds the plug 12 and the cable 14 at least partially along the insertion direction E.A second housing element 18 of the connector 10, which is arranged externally and surrounds the first housing element 18 at least partially along the insertion direction E, is designed to be movable along the insertion direction E with respect to the first housing element 16. To lock the connector 10 to the connector socket, the connector 10 has at least one connector-side locking element 20, which is designed to be locked with a corresponding connector socket-side locking element (not shown). Furthermore, the at least one connector-side locking element 20 is arranged at least partially between the first housing element 16 and the second housing element 18.By a relative movement of the second housing element 18 with respect to the first housing element 16 opposite to the insertion direction, the locking of the at least one connector-side locking element 20 and the connector socket-side locking element can be canceled or released. As shown in the . Figures 1 and 2 As shown, the connector 10 preferably has exactly two connector-side locking elements 20, which can be and / or are fastened to the first housing element 16 opposite one another with respect to the longitudinal axis L.

[0052] As in Figure 2As shown, the connector 10 has a sealing element 22 for sealing the connector 10, which is arranged within the first housing element 16, wherein the sealing element 22 surrounds the cable 14 at least in sections along the insertion direction E. The sealing element 22 is essentially hollow-cylindrical and can be rotationally symmetrical, in particular with respect to the longitudinal axis L of the connector 10. In other words, the rotational axis of the sealing element lies on the longitudinal axis L of the connector 10 or on the longitudinal axis of the first housing element 15.

[0053] Furthermore, the connector 10 has a securing means 24, which can be connected to the first housing element 16. In particular, it can be provided that the securing means 24 can be screwed into the first housing element in the insertion direction E. When the securing means 24 is connected to the first housing element 16, the securing means 24 moves relative to the first housing element in the insertion direction E, whereby the securing means 24 acts on a first contact surface 26 of the sealing element 22 in order to seal the sealing element 22 relative to the first housing element 16 and the cable 14 or relative to the cable sheath 17 of the cable 14.

[0054] The first contacting surface 26 is formed at an end of the sealing element 22 lying opposite to the insertion direction E and points substantially opposite to the insertion direction E. The securing means 24 is further designed to surround the cable 14 at least in sections along the insertion direction E and is substantially hollow-cylindrical.

[0055] Furthermore, the plug connector 10 has a stop element 28 arranged in the first housing element 16, which is arranged in front of the sealing element 22 in the insertion direction E. The stop element 28 is designed to surround the cable 14 at least partially along the insertion direction E. By connecting the securing means 24 to the first housing element 16, the sealing element 22 is squeezed between the stop element 28 and the securing means 24. In particular, by connecting the securing means 24 to the first housing element 16, the stop element is pressed onto a second contact surface 30 of the sealing element 22, wherein the second contact surface 30 points substantially in the insertion direction E.

[0056] By connecting the securing means 24 to the first housing element 16, the securing means 24 can act on the first contact surface 26 in such a way that an outer side 34 of a first sealing section 32 of the sealing element 22 is pressed and / or pushed against the inner side of the first housing element 16. Furthermore, an inner side 36 of the first sealing section 32 is pressed and / or pushed against the cable 14 or the cable sheath of the cable 14. The first sealing section 32 is a section of the sealing element 22 which extends, starting from the end of the sealing element 22 opposite the insertion direction E, at least in sections in the direction of the insertion direction E. The first sealing section 32 surrounds the cable 14 at least in sections along the insertion direction E.

[0057] Furthermore, by connecting the securing means 24 to the first housing element 16, the stop element 28 can act on the second contact surface 30 in such a way that an outer side 40 of a second sealing section 37 of the sealing element 22 is pressed and / or pushed against the inner side of the first housing element 16. Furthermore, an inner side 42 of the second sealing section 38 can be pressed and / or pushed against the cable 14 or the cable sheath of the cable 14. The second sealing section 38 is a section of the sealing element 22 which, starting from the end of the sealing element 22 lying in the insertion direction E, extends at least partially counter to the insertion direction E. The second sealing section 38 surrounds the cable 14 at least partially along the insertion direction E.

[0058] The sealing element 22 and the securing means 24 are arranged in particular in a substantially hollow-cylindrical section 44 of the first housing element 16, which at least partially surrounds the cable 14 along the insertion direction E. The stop element 28 can be arranged at least partially in the hollow-cylindrical section 44 of the first housing element 16. The first housing element 16 can furthermore have a shoulder and / or a constriction 46, which is arranged on the inside of the first housing element 16 and / or in the first housing element 16 and against which the stop element 28 bears in order to prevent displacement of the stop element 28 in the insertion direction E.

[0059] A detailed description of the first housing element 16, the sealing element 22, the securing means 24 and the stop element 28 is given below with reference to the Figure 3. Figure 3shows a state in which the sealing element 22 does not contact the stop element 28 and the securing means 24. The first contacting surface 26 of the sealing element 22 has a first circumferential recess 48, which extends in the insertion direction E into the sealing element 22, so that the first recess 48 is formed in a groove-like and / or groove-shaped manner on the first contacting surface 26. The first recess 48 further has an outer contacting section 50, which is inclined with respect to the longitudinal axis L of the plug connector 10 (represented by the dashed line) and points in the direction of the longitudinal axis L of the plug connector. Furthermore, the outer contacting section 50 merges into an inner contacting section 52, wherein the inner contacting section 52 is inclined with respect to the longitudinal axis L and points away from the longitudinal axis L.Furthermore, the outer contacting section 50 and the inner contacting section 52 connect the outside and the inside of the sealing element.

[0060] Furthermore, the end of the securing means 24 lying in the insertion direction E tapers so that it can be inserted into the first circumferential recess 48 by connecting the securing means 24 to the first housing element 16. In particular, the end of the securing means 24 lying in the insertion direction E is frustoconical in shape in order to engage in the first recess 48 and spread open the sealing element 22 when the securing means 24 is connected to the first housing element 16. This advantageously makes it possible for the securing means 24 to press and / or press the outer side 34 in the region of the first sealing section 32 and the inner side 36 in the region of the first sealing section 32 particularly well against the inside of the first housing element 16 or against the cable sheath of the cable 14.

[0061] Furthermore, due to its frustoconical and hollow-cylindrical design, the securing means 24 has a wall 54 which is tapered at an end lying in the insertion direction E. In other words, the wall thickness of the wall 54 decreases at the end lying in the insertion direction E. Furthermore, the wall 54 has an outer circumferential wall section 56 at the end lying in the insertion direction E, which is inclined with respect to the longitudinal axis L and points away from it. Furthermore, the outer wall section 56 essentially in the direction of the insertion direction E.

[0062] Advantageously, it is thus possible that, when connecting the securing means 24 to the first housing element 16, the outer wall section 56 of the securing means 24 contacts the outer contacting section 50 of the sealing element 22 and acts on it, so that the outer side 34 of the first sealing section 32 is pressed against the first housing element 16. Furthermore, the inner wall section 58 of the securing means 24 presses on the inner contacting section 52, so that the inner side 36 of the first sealing section 32 is pressed against the cable 14 or the cable sheath.

[0063] Advantageously, the inclination of the outer wall section 56 relative to the longitudinal axis L of the connector 10 can be greater than or equal to, preferably greater than, the inclination of the outer contacting section 50 relative to the longitudinal axis L of the connector 10. Accordingly, the outer side 34 of the first sealing section 32 can be better pressed against the first housing element 16.

[0064] Advantageously, the inclination of the inner wall section 58 relative to the longitudinal axis L of the connector 10 can be greater than or equal to, preferably greater than, the inclination of the inner contacting section 52 relative to the longitudinal axis L of the connector 10. Accordingly, the inner side 36 of the first sealing section 32 can be better pressed against the cable 14 or the cable sheath 17.

[0065] Advantageously, the wall 54 of the securing means 24 is blunted at the end lying in the insertion direction E to prevent damage to the sealing element 22. In particular, the wall 54 of the securing means 24 has an end wall section 60 at the end lying in the insertion direction E, which extends substantially perpendicular to the longitudinal axis L of the connector or perpendicular to the insertion direction E.

[0066] Like the first contacting surface 26, the second contacting surface 30 of the sealing element 22 has a second circumferential recess 62 which extends into the sealing element 22 opposite to the insertion direction E. The second recess 62 is in particular groove-like and / or shaped on the second contacting surface 30. The second recess 62 further has an outer contacting section 64 which is inclined with respect to the longitudinal axis L of the connector 10, wherein the outer contacting section 64 points substantially in the direction of the longitudinal axis L of the connector 10. Furthermore, the outer contacting section 64 can merge into an inner contacting section 66 of the second contacting surface 30, wherein the inner contacting section 64 is inclined with respect to the longitudinal axis L and points away from the longitudinal axis L.Furthermore, the outer side of the sealing element 22 and the inner side of the sealing element 22 are connected to one another by the second contacting surface 30 and in particular by the outer contacting section 64 and the inner contacting section 66.

[0067] The stop element 28 has a tapered end facing the insertion direction E, which can be inserted into the second recess 62 by connecting the securing means 24 to the first housing element 16. Advantageously, the second recess 62 allows the stop element 28 to press into the second recess 62 when the securing means 24 is connected to the first housing element 16, thus allowing the outer side 40 of the second sealing portion 38 to be pressed and / or pushed against the first housing element 16. Furthermore, the inner side 42 of the second sealing portion 38 can be pressed particularly well against the cable 14 or the cable sheath 17.

[0068] Furthermore, the stop element 28 has a substantially hollow cylindrical section 68, which extends at least partially along the longitudinal axis L of the connector 10 and / or along the insertion direction E. The hollow cylindrical section 68 also has the tapered end of the stop element 28. In other words, the wall thickness of the wall 70 of the stop element 28 decreases at the end opposite to the insertion direction E, running opposite to the insertion direction E. In particular, the tapered end of the stop element 28 has a rounded outer wall section 72. Furthermore, the wall 70 of the stop element 28 has, at the end opposite to the insertion direction E, an inner circumferential wall section 74, which is inclined relative to the longitudinal axis L of the connector 10 and points essentially in the direction of the longitudinal axis L.Furthermore, the inner wall section 74 points essentially opposite to the insertion direction E.

[0069] Advantageously, it is thus possible that, when connecting the securing means 24 to the first housing element 16, the rounded outer wall section 72 of the stop element 28 contacts and acts on the outer contacting section 64 of the sealing element, so that the outer side 40 of the second sealing section 38 is pressed against the first housing element 16. Furthermore, the inner wall section 74 of the stop element 28 can press on the inner contacting section 66, so that the inner side 42 of the second sealing section 38 is pressed against the cable 14 or the cable sheath.

[0070] Advantageously, the inclination of the inner wall section 74 relative to the longitudinal axis L of the connector 10 can be greater than or equal to, preferably greater than, the inclination of the inner contacting section 66 relative to the longitudinal axis L of the connector 10. Accordingly, the inner side 42 of the second sealing section 38 can be better pressed against the first housing element 16.

[0071] Advantageously, the wall 70 of the stop element 28 is blunted at the end opposite the insertion direction E to prevent damage to the sealing element 22. In particular, the stop element 28 has an end wall portion 76 at the end opposite the insertion direction E, which extends substantially perpendicular to the longitudinal axis L of the connector 10 or perpendicular to the insertion direction E. Furthermore, the end wall portion 76 connects the rounded outer wall portion 72 to the inner wall portion 74 of the stop element 28.

[0072] Furthermore, the stop element 28 and the securing means 24 have an inner diameter that is larger than the outer diameter of the cable 14, so that the cable 14 and / or the cable sheath 17 can be spaced apart from the stop element 28, in particular from the hollow cylindrical portion 68 of the stop element 28, and from the securing means 24.

[0073] Furthermore, the stop element 28 has a spacer section 78 which extends from the hollow cylindrical section 68 of the stop element 28 in the insertion direction E. The spacer section 78 enables the distance along the insertion direction E between the plug 12 and the sealing element 22 to be increased.

[0074] Furthermore, the plug connector 10 has a further sealing element 80, which is designed to seal the first housing element 16 from the plug connector socket when the plug connector 10 and plug connector socket are connected. In particular, the further sealing element 80 is arranged on an outer side of the first housing element 16. The further sealing element 80 has three sealing lips arranged circumferentially on the outer side of the first housing element 16.

[0075] The sealing element 22 and / or the further sealing element 80 can preferably be made of an elastic material such as rubber and / or caoutchouc in order to ensure the highest possible deformability and / or adaptability to the first housing element 16, the cable 15, the cable sheath 17 and / or the connector socket, thereby advantageously influencing the sealing effect.
