Definitions
- the invention relates to a receptacle housing for a plug element and/or mating plug element of an electrical plug-in connector in a plug-in direction of the plug-in connector, comprising a sealing section adapted to hold a sealing element for sealing up between the plug element and the mating plug element, wherein the sealing section comprises at least one counter retention element adapted to engage with a retention element formed at the sealing element in order to secure the sealing element against movements in parallel to the plug-in direction.
- the present invention relates to a sealing element for sealing up between a plug element and a mating plug element of an electrical plug-in connector, an axial direction of the sealing element running essentially in parallel to a plug-in direction for mating the plug element and the mating plug element.
- the present invention relates to an electrical plug-in connector.
- the plug-in connectors comprising the housings and the sealing elements are often used in hostile environments as they may be applied in vehicles for example. In these hostile environments, the plug-in connectors are exposed to vibrations, moisture, dirt, dust and possibly chemical aggressive substances. When aggressive, corroding or electrically conductive substances would get into a connection area between mating contact elements of a connector, they could cause interruptions of the power supply or false circuits.
- the connectors have to be provided with sealings which prevent any harmful substances from entering the connector and affecting the contact elements arranged therein. It is desired to hermetically seal the connector.
- An overall sealing should at least be liquid-tight and optimally gas-tight.
- a sealed electrical connector according to the prior art is described in the US patent specification US 7,540, 775 B2 for example which shows a sealed electrical plug-in connector.
- a plug seal of this connector is arranged between a header shroud and a receptacle housing.
- a flange formed at the seal and radially extending therefrom is jammed between the bottom formed at the receptacle housing and a rim of the header shroud.
- an object underlying the invention is to provide an electrical plug-in connector which is sealable and reliable, yet easy to use and to assemble.
- the sealing element further comprises at least one retention element adapted to engage with a counter retention element formed at least at one of the plug element and/or the counter plug element according to the present invention in order to secure the sealing element against movements in the axial direction and/or plug-in direction.
- the plug-in connector comprises at least one sealing element and a receptacle housing according to the present invention.
- the sealing element may be properly retained in its mounted position at the plug element and/or the mating plug element. It may thereby not be deformed, folded or wrinkled while mating the plug element and the mating plug element. Further, the sealing element may not get pulled out of its mounted position so easily when un-mating the plug element and the mating plug element.
- the plug element may be a first connector element and the mating plug element may be a second connector element of an electrical plug-in connector, wherein the first connector element in the second connector element may have complementary shapes in order to be brought into engagement with each other when mating. During mating and un-mating the sealing element may be accurately kept in place while bringing the plug element and the mating plug element into engagement with each other.
- the at least one counter retention element is resiliently deflectable in a direction extending essentially perpendicularly to the plug-in direction.
- the counter retention element may be formed as snap-in tongue at least partially extending in parallel to the plug-in direction.
- the counter retention element may have spring characteristics in a direction extending essentially perpendicularly to the plug-in direction whereby the counter retention element may snap into the retention element and thereby may be easily brought into engagement with the retention element.
- a cavity for at least partially receiving a header shroud of the plug element or the mating plug element may be formed between the counter retention element and a wall of the receptacle housing. This cavity may accommodate the header shroud in a fully mated state of the plug element and the mating plug element.
- the sealing element and/or the counter retention element may thereby be immobilized between the header shroud and the wall of the receptacle housing, such that the sealing element and/or the counter retention element may not move in a radial direction or a direction running essentially perpendicularly to the plug-in direction.
- the retention element and the counter retention element may be held in a retention position and/or mounted position, respectively.
- the at least one retention element may at least partially extend in a radial direction of the sealing element, wherein the radial direction is extending essentially perpendicularly to the axial direction.
- the retention element may be brought into engagement with the counter retention element in such a way that movements of the sealing elements in parallel to the axial direction and/or plug-in direction may be blocked and the sealing element securely immobilized.
- the at least one retention element may be formed as a recess. Thereby, the counter retention element may protrude into the retention element for blocking and/or latching the sealing element in its mounted position.
- the at least one retention element may be formed as a groove which at least partially extends along a circumference of the sealing element.
- the counter retention element may interact with the retention element along the circumference of the sealing element in order to secure the sealing element along its circumference and prevent even a partial folding or wrinkling as well as partial displacement of the sealing element with respect to its mounted position.
- the sealing element may comprise a sealing portion and a retention portion attached to the sealing portion and providing the at least one retention element.
- the sealing function may be assigned to the sealing portion and the retention function may be assigned to the retention portion.
- the sealing portion may be designed for optimal sealing characteristics and the retention portion may be designed for optimal retention characteristics.
- the sealing portion and the latching portion may have an essentially planar side on a side of the sealing element lying opposite the retention element. On the planar side, the sealing portion and the latching portion may be aligned with respect to each other, at least in parallel to the axial direction. Any sealing protrusions such as lamellas on a sideline opposite to the planar side may provide a structured side of the sealing element. Hence, the sealing element may be brought into flush abutment with its planar side to the plug element and/or mating plug element which enhances sealing up the electrical connector while on the other side, the retention element may be easily accessed.
- the retention element may provide an engagement surface in form of a bevel which is at least partially slanted with respect to the axial direction. Thereby, the counter retention element may easily be brought into engagement with the retention element in that the counter retention element may slip into the retention element along the bevelled engagement surface.
- the sealing element may at least partially have a ring-like cross-section. Thereby, it may be elastically deformable in a radial direction. Thus, it may be elastically tensioned when wrapped around a plug portion for example in order to enhance sealing characteristics.
- the sealing element may generally have a tubular shape. Hence, the sealing element may provide a tubular inner circumference as well as a tubular outer circumference which may be brought into flush abutment with the plug element and/or the mating plug element.
- the plug-in connector comprises at least one plug element and a mating plug element, wherein a fully mated state of at least one plug element and the at least one mating plug element, the retention element and the counter retention element are blocked in a retention position. Thereby, accidentally disengaging the retention element and the counter element may be prevented.
- the retention element and the counter retention element may be adapted for engagement with each other in the mounted position and/or locked or retained position of the sealing element.
- the retention element and the counter retention element may overlap with the plug element and the mating plug element in a direction perpendicular to the plug-in direction. Thereby, for example in a radial direction of the plug-in connector, any displacement of the retention element and the counter retention element is omitted which helps in securely immobilizing the sealing element in its mounted position.

Abstract
Description
- The invention relates to a receptacle housing for a plug element and/or mating plug element of an electrical plug-in connector in a plug-in direction of the plug-in connector, comprising a sealing section adapted to hold a sealing element for sealing up between the plug element and the mating plug element, wherein the sealing section comprises at least one counter retention element adapted to engage with a retention element formed at the sealing element in order to secure the sealing element against movements in parallel to the plug-in direction.
- Further, the present invention relates to a sealing element for sealing up between a plug element and a mating plug element of an electrical plug-in connector, an axial direction of the sealing element running essentially in parallel to a plug-in direction for mating the plug element and the mating plug element.
- Moreover, the present invention relates to an electrical plug-in connector.
- Sealing elements, receptacle housings and electrical plug-in connectors mentioned above are known. The plug-in connectors comprising the housings and the sealing elements are often used in hostile environments as they may be applied in vehicles for example. In these hostile environments, the plug-in connectors are exposed to vibrations, moisture, dirt, dust and possibly chemical aggressive substances. When aggressive, corroding or electrically conductive substances would get into a connection area between mating contact elements of a connector, they could cause interruptions of the power supply or false circuits. Hence, the connectors have to be provided with sealings which prevent any harmful substances from entering the connector and affecting the contact elements arranged therein. It is desired to hermetically seal the connector. An overall sealing should at least be liquid-tight and optimally gas-tight.
- A sealed electrical connector according to the prior art is described in the US patent specification
US 7,540, 775 B2 for example which shows a sealed electrical plug-in connector. A plug seal of this connector is arranged between a header shroud and a receptacle housing. A flange formed at the seal and radially extending therefrom is jammed between the bottom formed at the receptacle housing and a rim of the header shroud. - Known connectors as mentioned above and described in the prior art suffer from the disadvantages that their sealings may deform, fold or wrinkle while mating the connector which could lead to an insufficient abutment of the sealing to the housing and/or header shroud, whereby harmful substances could enter the connector. Further, known sealings suffer from the disadvantage that the sealings may be pulled off or out of the connector when un-mating the connector making it cumbersome to re-mate the connector properly.
- In view of the disadvantages of the prior art mentioned above, an object underlying the invention is to provide an electrical plug-in connector which is sealable and reliable, yet easy to use and to assemble.
- This object is achieved according to the invention for the receptacle housing mentioned in the beginning of the description in that the at least one counter retention element is resiliently deflectable.
- For the sealing element mentioned at the beginning of the description, the above-mentioned problems are solved in that the sealing element further comprises at least one retention element adapted to engage with a counter retention element formed at least at one of the plug element and/or the counter plug element according to the present invention in order to secure the sealing element against movements in the axial direction and/or plug-in direction.
- For the electrical plug-in connector mentioned in the beginning of the description, the above-mentioned problems are solved in that the plug-in connector comprises at least one sealing element and a receptacle housing according to the present invention.
- These simple solutions provide that the sealing element may be properly retained in its mounted position at the plug element and/or the mating plug element. It may thereby not be deformed, folded or wrinkled while mating the plug element and the mating plug element. Further, the sealing element may not get pulled out of its mounted position so easily when un-mating the plug element and the mating plug element. The plug element may be a first connector element and the mating plug element may be a second connector element of an electrical plug-in connector, wherein the first connector element in the second connector element may have complementary shapes in order to be brought into engagement with each other when mating. During mating and un-mating the sealing element may be accurately kept in place while bringing the plug element and the mating plug element into engagement with each other.
- The solutions according to the invention can be combined as desired and further improved by the following further embodiments that are advantageous on their own in each case:
- According to a first further embodiment of a receptacle housing according to the present invention it may be provided that the at least one counter retention element is resiliently deflectable in a direction extending essentially perpendicularly to the plug-in direction. The counter retention element may be formed as snap-in tongue at least partially extending in parallel to the plug-in direction. Thereby, the counter retention element may have spring characteristics in a direction extending essentially perpendicularly to the plug-in direction whereby the counter retention element may snap into the retention element and thereby may be easily brought into engagement with the retention element.
- A cavity for at least partially receiving a header shroud of the plug element or the mating plug element may be formed between the counter retention element and a wall of the receptacle housing. This cavity may accommodate the header shroud in a fully mated state of the plug element and the mating plug element. The sealing element and/or the counter retention element may thereby be immobilized between the header shroud and the wall of the receptacle housing, such that the sealing element and/or the counter retention element may not move in a radial direction or a direction running essentially perpendicularly to the plug-in direction. Hence, the retention element and the counter retention element may be held in a retention position and/or mounted position, respectively.
- According to a further embodiment of the sealing element, the at least one retention element may at least partially extend in a radial direction of the sealing element, wherein the radial direction is extending essentially perpendicularly to the axial direction. Thereby, the retention element may be brought into engagement with the counter retention element in such a way that movements of the sealing elements in parallel to the axial direction and/or plug-in direction may be blocked and the sealing element securely immobilized.
- The at least one retention element may be formed as a recess. Thereby, the counter retention element may protrude into the retention element for blocking and/or latching the sealing element in its mounted position.
- The at least one retention element may be formed as a groove which at least partially extends along a circumference of the sealing element. Thereby, the counter retention element may interact with the retention element along the circumference of the sealing element in order to secure the sealing element along its circumference and prevent even a partial folding or wrinkling as well as partial displacement of the sealing element with respect to its mounted position.
- The sealing element may comprise a sealing portion and a retention portion attached to the sealing portion and providing the at least one retention element. Thereby, the sealing function may be assigned to the sealing portion and the retention function may be assigned to the retention portion. Hence, the sealing portion may be designed for optimal sealing characteristics and the retention portion may be designed for optimal retention characteristics.
- The sealing portion and the latching portion may have an essentially planar side on a side of the sealing element lying opposite the retention element. On the planar side, the sealing portion and the latching portion may be aligned with respect to each other, at least in parallel to the axial direction. Any sealing protrusions such as lamellas on a sideline opposite to the planar side may provide a structured side of the sealing element. Hence, the sealing element may be brought into flush abutment with its planar side to the plug element and/or mating plug element which enhances sealing up the electrical connector while on the other side, the retention element may be easily accessed.
- The retention element may provide an engagement surface in form of a bevel which is at least partially slanted with respect to the axial direction. Thereby, the counter retention element may easily be brought into engagement with the retention element in that the counter retention element may slip into the retention element along the bevelled engagement surface.
- The sealing element may at least partially have a ring-like cross-section. Thereby, it may be elastically deformable in a radial direction. Thus, it may be elastically tensioned when wrapped around a plug portion for example in order to enhance sealing characteristics.
- The sealing element may generally have a tubular shape. Hence, the sealing element may provide a tubular inner circumference as well as a tubular outer circumference which may be brought into flush abutment with the plug element and/or the mating plug element.
- According to a further possible embodiment of an electrical plug-in connector according to the present invention it may be provided that the plug-in connector comprises at least one plug element and a mating plug element, wherein a fully mated state of at least one plug element and the at least one mating plug element, the retention element and the counter retention element are blocked in a retention position. Thereby, accidentally disengaging the retention element and the counter element may be prevented. The retention element and the counter retention element may be adapted for engagement with each other in the mounted position and/or locked or retained position of the sealing element.
- In the fully mated state, the retention element and the counter retention element may overlap with the plug element and the mating plug element in a direction perpendicular to the plug-in direction. Thereby, for example in a radial direction of the plug-in connector, any displacement of the retention element and the counter retention element is omitted which helps in securely immobilizing the sealing element in its mounted position.
- The invention will be described in more detail by way of example hereinafter using advantageous embodiments and with reference to the drawings. The described embodiments are only possible configurations in which the individual features may however, as described above, be implemented independently of each other or may be omitted. Equal elements illustrated in the drawings are provided with equal reference signs. Redundant parts of the description relating to equal elements illustrated in different drawings are left out.

Fig. 8 . - A construction of a
plug element 1 according to the invention will first be described in the following with reference toFig. 1 , which shows a schematic perspective view of theplug element 1. Theplug element 1 comprises ahousing 2 and asealing element 3. - The
housing 2 has aplug portion 2a and aterminal portion 2b. Theplug portion 2a is adapted to be mated with a mating plug connector (not yet shown) in a plug direction P of theplug element 1 running in parallel to a height direction Z of theplug element 1. In other words, theplug element 1 may be plugged into the mating plug element in the plug direction P. The mating plug element may be plugged into theplug element 1 in the mating plug direction P'. In theplug portion 2a, anouter shell 4 of thehousing 2 has anupper rim 4a and aninner circumference 4b. Theouter shell 4 surrounds aplug 5 of theplug element 1 formed by an inner shell. Theplug 5 has afront side 5a facing into the plug direction P and anouter circumference 5b. - A
receptacle 6 of theplug element 1 is formed between theinner circumference 4b of theouter shell 4 and theouter circumference 5b of theplug 5. A bottom 6a of thereceptacle 6 faces into the plug direction P. At thefront side 5a of theplug 5,contact receptacles 7 of theplug element 1 have anopening 7a through which a mating contact (not shown) may be mated with an electrical contact (not shown), e.g. a terminal, socket and/or pin may be plugged into thecontact receptacles 7 in the mating plug direction P'. Thecontact receptacles 7 are arranged in two rows 8a and 8b ofcontact receptacles 7. In each row 8a and 8b, theopening 7a of thecontact receptacles 7 are aligned in a lateral direction X of theplug element 1. The lateral direction X extends perpendicularly to the height direction Z. The rows 8a, 8b ofcontact receptacles 7 are arranged next to each other in a cross direction Y of thecontact element 1. The cross direction Y extends perpendicularly to the lateral direction X and the height direction Z. - The
outer shell 4, theplug 5 and thereceptacle 6 are arranged essentially concentrically with respect to a middle axis M1 of theplug element 1 and a middle axis M2 of thehousing 2. Hence, theinner circumference 4b of theouter shell 4 and theouter circumference 5b of theplug 5 are extending essentially in parallel to each other in the plug direction P. Further, thehousing 2 is provided with a latchingelement 9 for latching theplug element 1 and the mating plug element in a fully mated state B (not yet shown). The latchingelement 9 comprises aguidance 9a and alatch 9b. Theguidance 9b extends essentially in parallel to the plug direction P. Thelatch 9b extends almost in parallel to the plug direction B and is slightly slanted with respect to the plug direction P in order to exert a spring force acting perpendicularly to the plug direction P when interacting with a mating latching element (not shown) of a mating plug element. Aplug face 10 of theplug element 1 faces into the plug direction P and is formed by the respective shapes and contours of theplug portion 2a, i.e. theouter shell 4, theplug 5, thereceptacle 6, thecontact receptacles 7 and the latchingelement 9 in a projection in parallel to the plug direction P. - The sealing
element 3 comprises a ring member 30 and tworetention elements 31 a. Anouter circumference 32 of the ring member 30 is provided withlamellas 32a extending along theouter circumference 32. Aninner circumference 33 of the ring member 30 is also provided withlamella 33a extending in parallel to each other along theinner circumference 33. The ring member 30 forms a passage 34 with itsinner circumference 33. The passage 34 extends in an axial direction Q of the ring member 30 extending essentially in parallel to a middle axis M3 of the ring member 30 and the sealingelement 1 from afront face 30a of the ring member to arear face 30b of the ring member. Therear face 30b of the ring member 30 faces into an insertion direction I of the sealingelement 3, in which insertion direction I the sealingelement 3 is adapted to be inserted into thereceptacle 6 of thehousing 2. A retention element 31 of the sealingelement 3 is arranged at theouter circumference 32 of the ring member 30 in the vicinity of arear face 30b of the ring member. The retention element 31 protrudes from theouter circumference 32 of the ring member 30 in a second radial direction R2. -
Fig. 2 shows a schematic bottom view of theplug element 1. Here it becomes apparent that thecontact receptacles 7 extend through theplug element 1 in parallel to the plug direction P. Hence, at a rear face 4c of theouter shell 4, thecontact receptacles 7 haverear openings 7b opening towards the plug direction P.Fig. 3 shows a schematic side view of theplug element 1. -
Fig. 4 is a schematic front view of theplug element 1 in a pre-mated state A with the sealingelement 3 in the mounted position S. The sealingelement 3 is inserted into thehousing 2 in the mounted position S and captively held in a retention position T of the retention element 31. The sealing element is arranged within thereceptacle 6 so that theinner circumference 33 of the sealingelement 3 snugly encloses theouter circumference 5b of theplug 5. Theouter circumference 32 of the sealingelement 3 is distanced from theinner circumference 4b of theouter shell 4 such that aclearance 6b for accommodating a header shroud (not yet shown) of a mating plug element (not yet shown) extends between theinner circumference 4b of theouter shell 4 and theouter circumference 5b of the plug in the radial directions R1 and R2. -
Fig. 5 shows a schematic cross-sectional view of theplug element 1 along the cross-section line A-A illustrated inFig. 3 . Here theplug element 1 is in the pre-mated stated A and ready to be brought into engagement with a mating plug element (not yet shown) in the plug direction P. The sealingelement 3 is inserted into thereceptacle 6 parallel to the insertion direction l. - The sealing
element 3 comprises a sealingportion 3a and aretention portion 3b. The sealingportion 3a is arranged above theretention portion 3b, i.e. before theretention portion 3b in the insertion direction I or against the plug direction P. Theinner circumference 33 of the sealingelement 3 in the region of theretention portion 3a abuts theplug 5. Theinner circumference 33 snugly encompasses a wall portion 5c of theplug 5, in particular anouter circumference 5d of the wall portion 5c. Therear face 30b formed at theretention portion 3b of theplug element 3 abuts the bottom 6a of thereceptacle 6. Hence, the sealingelement 3 is supported with itsrear face 30b at the bottom 6a of thereceptacle 6 such that forces acting in the insertion direction I and/or against the plug direction P may be absorbed at the bottom 6a of thereceptacle 6. - A
retention element 31 b in the form of a recess or groove extends along theinner circumference 33 of the sealingelement 3. Acounter retention element 11 formed at theouter circumference 5b of theplug 5 engages with theretention element 31 b. Thereby, pulling out the sealingelement 3 of thereceptacle 6 in a direction opposite to the insertion direction I is prevented. Thecounter retention element 11 comprises adetent 11a in the form of a latching nose, aspring element 11 b and a spring section 11c. Thedetent 11a is formed at thespring element 11 b and protrudes therefrom in the radial direction R, R2. Thespring element 11 b extends essentially in parallel to the plug direction P and/or insertion direction I. Thespring element 11 b may have the form of a lamella or latching tongue which may be connected to thehousing 2 via the spring section 11 c which may render thespring element 11 b resiliently deflectable. The spring section 11c may comprise a recess or attenuation section where the material of thehousing 2, e.g. of a wall of thehousing 2, e.g. of theplug 5, may be weakened such that an elasticity of the spring section 11c is higher than an elasticity of thespring element 11b and/or thehousing 2, in particular of their walls. Hence, thespring element 11 b and therewith thedetent 11a may be at least slightly resiliently pivotable about the spring section 11c. In order to facilitate an insertion of a header shroud (not yet shown) of a mating plug element (not yet shown) into theclearance 6b in the mating plug direction P', the sealing element is provided with afront bevel 37. -
Fig. 6 shows a schematic cross-sectional view of an electrical plug-inconnector 200 comprising a plug element 1' and a matingelement plug element 100 in a fully mated state B with the sealingelement 3 in the mounted position S and/orretention element 31 c retention position T according to another embodiment of the present invention. The plug element 1' comprises a housing 2' with an outer shell 4' and aplug 5'. Aheader shroud 101 of themating plug element 100 is inserted into theclearance 6b between theinner circumference 4b of the outer shell 4' and theouter circumference 32 of the sealing element 3' in the region of the sealingportion 3a. In the region of theretention portion 3b, atip 101 a of theheader shroud 101 is arranged in the vicinity of the bottom 6a of thereceptacle 6. Theouter circumference 101 b of theheader shroud 101 faces theinner circumference 4b of the outer shell 4'. Aninner circumference 101 c of theheader shroud 100 faces a counter retention element 11' formed at the plug element 1'. - The counter retention element 11' comprises a
detent 11 a in the form of a snap-in nose formed at aspring element 11 b in the form of a latching tongue extending in the plug direction P. Thespring element 11 b is attached to the outer shell 4' via a spring section 11c about which thespring element 11 b is resiliently deflectable such that thedetent 11a may be displaced in the radial direction R1, i.e. in a direction extending perpendicularly to the insertion direction I such that thedetent 11a may be displaced by therear face 30b while inserting the sealingelement 3 into a clearance between theouter circumference 5b of theplug 5' and theretention element 11a. Displacement of the retention element 11' perpendicularly to the insertion direction I is facilitated in that therear face 30b of the spring element 3' is provided with abevel 30d and accordingly, the detent is also provided with abevel 11 d. - In the retention position T of the retention element 11' shown in
Fig. 6 , theheader shroud 101 and in particular theinner circumference 101 c of theheader shroud 101 blocks any movement of the counter retention element 11' in the radial direction R1 and thereby prevents disengaging thedetent 11a and theretention element 31 c. Theplug 5', theretention portion 3b, the counter retention element 11', theheader shroud 101 and the outer shell 4', in particular theinner circumference 4b of the outer shell 4' overlap in a projection along the radial direction R1, thereby securing the counter retention element 11' in the retention position T. -
