Abstract
Description
- The present invention generally relates to an electrical connector with an interface element that is embodied to receive a retainer ring.
- It is known from the state of the art to provide an electrical connector with a contact element that is arranged in a body. The body is often made of EPDM material. The body is covered by a thick wall representing a conductive layer. The thick wall comprises at an outer face a groove that receives a retainer ring.
- An object of the invention is to provide an electrical connector that can be produced in a cost-efficient and simple manner.
- The object of the invention is achieved by the electrical connector of claim 1.
- Further embodiments of the invention are disclosed in the dependent claims.
- The proposed electrical connector can be produced in a simple manner with low costs.
- The simple production is attained by coating the insulating body with an electrically conducting layer. The layer can be easily damaged by fixing an element for example a the retainer ring or a sensor element to the layer or by any relative movement between the element and the insulating body due to usage of the connector, e.g. by heating up and cooling down due to varying electrical load or environmental temperature.
- Therefore, an interface element is provided that is arranged between the element and the layer. The interface element protects the layer. Therefore, the element can be fixed to the connector without damaging the layer.
- The replacement of the thick conducting wall by the coated thin conducting layer reduces the costs and simplifies the production process. The interface element provides a simple and secure fixing of the element without damaging the damageable conducting layer.
- In a further embodiment, the element is a retainer ring or a sensor element. The proposed structure assists the fixing of a retainer ring or a sensor element to the connector.
- In a further embodiment the first recess is of a partial circular shape or of a circular shape. The partial circular shape or the circular shape provides a secure form-fit or force-fit fixing of the interface element.
- In a further embodiment the interface element is of partial circular shape or of a circular shape. The partial circular shape or the circular shape provides a secure form-fit or force-fit fixing of an element with a partial circular shape or with a circular shape.
- In a further embodiment the second recess is of a partial circular shape or of a circular shape. The partial circular shape improves the fixing of an element with a partial circular shape. The circular shape improves the fixing of an element with a circular shape.
- In a further embodiment, the layer is made of a sprayed layer. Spraying the layer simplifies the production process and reduces the costs. The sprayed layer provides a sufficient conductivity.
- In a further embodiment, the layer has a thickness that is smaller than 0.3 mm, preferably smaller than 0.1 mm. This thickness is sufficient for providing the necessary electric conductivity for electrical grounding of the connector. The electrical grounding is necessary for a high-voltage and/or a high-current application of the connector.
- In a further embodiment, the interface element is embodied as an open ring that can be flexibly bent to a larger radius by mounting the interface element onto the connector or to a smaller radius for mounting the interface element on the retainer ring. Furthermore, the shape of an open ring can be produced in an easy and cost-efficient manner. Furthermore, the open-ring structure provides a secure fixing of the interface element to the connector and to the retainer ring.
- In a further embodiment, the recess for receiving the interface element is formed in a partly-circular cross-section along a longitudinal axis of the connecting section. The partly-circular cross-section provides a simple mounting of the interface element and a sufficient fixing of the interface element and the retainer ring.
- In a further embodiment, the recess comprises a cross-section with at least one protrusion and at least one lug for receiving a radial inner face of the interface element. The arrangement of the at least one protrusion and at least one lug improves the fixing of the interface element from moving or pulling off the interface element from the electrical connector.
- In a further embodiment, the body is made of a mold material, e. g. comprising silicone or EPDM or TPE. The production of the body by using a mold material is cost-efficient and can be combined with the low-cost process of spraying the conducting layer on the body. Therefore, the production of the connector is simplified and can be performed at low costs.
- In a further embodiment, the interface element is made of a flexible material, e. g. with a Shore hardness of A20 or higher.
- In a further embodiment, the interface element is made of a rigid material, e. g. thermoplastics. Also, a rigid material can be used for the interface element because it is still sufficiently soft for mounting the interface element to the connector without damaging the conducting layer. The interface element could also be made of an elastomeric material with a Shore hardness above A40. The interface element could also be made of an elastomeric material with reinforcement by e.g. metal insert elements.
- In a further embodiment, the interface element is made of electrically-conducting material. Therefore, the retainer ring that may be made of electrically-conducting material is also electrically connected to the electrically conducting layer.
- In a further embodiment, the interface element comprises a flexible section. The flexible section improves the flexibility of the interface element. Other parts of the interface element may be made of stiffer material. The stiffer material may increase the fixing forces that hold the retainer ring to the connector.
- In a further embodiment, the interface element is made of several elements that are connected by flexible parts. This embodiment increases the flexibility without reducing the fixing forces.

Figure 1 refers to an exemplary embodiment, wherein a schematic cross-section of a connector 1 is shown that compriseselectrical contact elements 2 that are arranged in an electrically-insulatingbody 3. Thebody 3 is covered with an electrically-conductinglayer 4. Thecontact elements 2 are arranged in a connecting section at a front end of the connector 1 that is provided for being plugged to acorresponding connector 6. Thebody 3 comprises aninterface element 7 that is arranged on an outer face of the connector 1. Theinterface element 7 is provided for fixing an element that is embodied as aretainer ring 8. Theinterface element 7 comprises afirst recess 15 with the shape of acircular groove 16 that is provided for receiving a part of a radial inner shape of theretainer ring 8. The connector 1 comprises acable 9 with conductors that are fixed to thecontact elements 2. Thebody 3 of the connector 1 has anend section 10 with a reduced diameter. At theend section 10, aplate 11 is mounted on the connector 1 abutting against aside wall 12 of thebody 3. Theplate 11 is fixed byrods 13 to thefurther connector 6. Therods 13 may be guided through holes of theplate 11 and fixed to theplate 11 by means ofscrews 14. Theretainer ring 8 is arranged within twoopposite rods 13 and holds the connector 1 in a stable position within therods 13. Theretainer ring 8 represents a theft protection system and prevents an easy removal of the connector 1. In particular if high voltages or high current is guided through the connector 1, a simple removal of the connector 1 should be prevented. - The
retainer ring 8 is made of a hard material to hold the connector 1 in a predetermined orientation for example referring to a device mounted on thecorresponding connector 6. The correspondingconnector 6 may comprise afurther contact element 42 that fits to thecontact element 2, wherein thefurther contact element 42 is arranged within a further electrically insulatingbody 43. Theretainer ring 8 may be made of metal with sharp edges that may damage thelayer 4 during the mounting of theretainer ring 8 on the connector 1 and/or during product usage. Thebody 3 is made of an insulating material, e. g. plastic, silicone or EPDM or TPE. In one embodiment, thebody 3 is made of molded material. This provides a cost-efficient and simple manner of production of the connector 1 with the embeddedcontact elements 2. Thelayer 4 is made of a thin layer, e. g. with a thickness in the range of 3 mm or less. Preferably, thelayer 4 has a thickness smaller than 0.1 mm. The function of thelayer 4 is to provide an electrically-conducting layer for electrical grounding. Thethin layer 4 is sufficient to provide the necessary grounding and is cost-efficient in production. In a further embodiment, thelayer 4 is coated on thebody 3 by spraying material on thebody 3. The spraying is a simple and cost-efficient production method that can e. g. be easily combined with molding thebody 3. - The
interface element 7 may be made of a flexible material such as rubbers (LSR, EPDM, HTV, TPE) with a Shore hardness A30-A50 or also higher hardness such as A60-A80. Depending on the embodiment, the interface element may also be made of other materials, e. g. of rigid materials such as thermoplastics (PP, PA, ABS, PVC and so on). Furthermore, the material of theinterface element 7 may be UV-resistant and may be electrically-conductive. - The connector 1 has a specific shape on the outer face for example in the connecting
section 5 to provide a recess or a shape for receiving and fixing theinterface element 7. Theinterface element 7 itself also comprises a shape or recess for receiving a part of theretainer ring 8 on an outer face. - The
retainer ring 8 may be made of metal, at least of a hard material and is inserted in the interface element before or during an installation process of the connector 1 to thefurther connector 6. The connectingsection 5 of thebody 3 can be pressed together before the installation on thefurther connector 6 to facilitate the mounting of theinterface element 7 and/or theretainer ring 8. Theinterface element 7 is either inserted by a cable jointer or is mounted on the connector in the factory by producing the connector 1. If the interface element is inserted by the cable jointer, it is preferably prior to that mounted on the inside of theretainer ring 8. Theinterface element 7 has a groove on the outside for theretainer ring 8 to be positioned in. On an inside, the interface element comprises a shape corresponding to the shape of an outer face of the connector 1. The corresponding shapes are designed to improve the force-fit and/or form-fit connection. The corresponding shapes are preferably further optimized to minimize electrical stress in the body material. The shapes may also allow sliding theretainer ring 8 with the interface element over the connector 1 and allow for maximum pull-off forces once the connector 1 is installed on thefurther connector 6. - Preferably the pull-off forces are also very high even when the connector 1 is not yet installed on the
corresponding connector 6. The proposed connector provides a cost reduction by having theinterface element 7 mounted after the molding of thebody 3 and coated thebody 3 with theconductive layer 4. This avoids costly overmolding with increased cycle time and increased molding efforts. Thelayer 4 may consist of the same material as thebody 3, e. g. silicone or polymer, and mixed with electrically-conductive material, e. g. carbon black. Thelayer 4 may be put on thebody 3 by dipcoating or by painting or by spraying. Furthermore, powder-coating with a curing process may be used for coating thebody 3 with thelayer 4. Thelayer 4 may cover the entire outer surface of the body or parts of it, as depending on the design selected areas may not require a conductive coating from the electrical point of view. This may reduce the cost. A further cost reduction is attained by having theinterface element 7 made of lower-cost material, e. g. EPDM, HTV or thermoplastic or elastomeric materials. Furthermore, the connector 1 can also be supplied without theinterface element 7 if a customer does not require aretainer ring 8. -
Figures 2 to 4 illustrate in schematic views several embodiments of theinterface element 7 and the connector 1. The cross-sections of thefigures 2 to 4 are arranged through amiddle axis 20 of the connector 1. The shown shapes are axially symmetric to the middle axis. -
Figure 2 depicts a partial cross-sectional view of theinterface element 7, theretainer ring 8 and a part of thelayer 4 and thebody 3. The connector 1 comprises at anouter face 19 an annularfirst recess 15. Thefirst recess 15 is provided to at least partly receive an inner part of theannular interface element 7.Figure 2 shows an embodiment of the connector 1 with afirst recess 15 with an evenly rounded cross-section. Theinterface element 7 also comprises a radialinner face 18 that is also evenly rounded and fits to theouter face 19 of the connector 1. In the shown embodiment, theentire interface element 7 is arranged within thefirst recess 15. Depending on the used embodiment, theinterface element 7 may protrude above the connector 1. Theinterface element 7 comprises an annularsecond recess 16. Thesecond recess 16 is embodied in the shown embodiment as a simple rectangular groove. Theretainer ring 8 is partly arranged with an inner section in thesecond recess 16. The dimension of thesecond recess 16 may have e.g. a width of 2 mm and a depth of 3 mm. Apart from receiving aretainer ring 8 therecess 16 may receive a device for monitoring e.g. inductive sensor or thermal sensor. -
Figure 3 shows a further embodiment of a connector 1 and aninterface element 7, wherein the annularfirst recess 15 of the connector 1 has an unevenly rounded cross-section with achamfer 21 on the right-hand side. Theinterface element 7 has a corresponding shape that fits in thefirst recess 15. The shape of theinterface element 7 allows for low slide-on forces. This shape may be of advantage if theinterface element 7 is slid into position together with theretainer ring 8 by an installer. Theinterface element 7 has an annularinner face 18 that is mostly radially oriented on the left-hand side to increase the form-fit and force-fit connection and to increase pull-off forces once the connector 1 is installed. Theinner face 18 of theinterface element 7 on the right-hand side also has achamfer 21 that assists sliding theinterface element 7 coming from the left-hand side to thefirst recess 15. The sliding of theinterface element 7 may be improved by oil, e. g. installation silicone oil. For secure fixing of theinterface element 7, an adhesive, e. g. a silicone adhesive, may also be used. The cross-section of thesecond recess 16 is the same as infigure 2 . - The
interface element 7 comprises at an outer face a protrudingsecond side wall 22 that is embodied as a ring face. Thesecond side wall 22 prevents during the mounting of the retainer ring that theretainer ring 8 may be slid to the right-hand side coming from the left-hand side over theinterface element 7. Thesecond side wall 22 protrudes above afirst section 23 of theinterface element 7 over that theretainer ring 8 has to be pulled to rest in thesecond recess 16. Thesecond side wall 22 is arranged at a predetermined distance from thesecond recess 16. Thesecond side wall 22 prevents theretainer ring 8 from being pushed to thelayer 4. Thesecond side wall 22 may also be used to push theinterface element 7 into position with a device. -
Figure 4 shows a further embodiment of aninterface element 7 and a connector 1, wherein the annularfirst recess 15 at the outer face of the connector 1 comprisesseveral protrusions middle axis 20 that represents a longitudinal axis of the connector 1. In the shown embodiment, there are threeprotrusions lugs interface element 7 and theretainer ring 8 are mounted on the connector 1 from the left-hand side and moved to the right-hand side. A first mountingsection 30 of the outer face of the connector 1 has a smaller radial distance from themiddle axis 20 than thefirst protrusion 24. Thefirst protrusion 24 is also embodied as an annular protrusion. Beside thefirst protrusion 24, afirst lug 27 is arranged that has the same radial distance to themiddle axis 20 as the first mountingsection 30. Beside thefirst lug 27, thesecond protrusion 25 is arranged. Thesecond protrusion 25 is also an annular protrusion and has a larger radial distance to themiddle axis 20 than thefirst protrusion 24. Beside thesecond protrusion 25, asecond lug 28 is arranged. - The
second lug 28 has the same radial distance to themiddle axis 20 as the first mountingsection 30. Beside thesecond lug 28, a thirdannular protrusion 26 is arranged. Thethird protrusion 26 has the same radial distance to themiddle axis 20 as thesecond protrusion 25. Beside thethird protrusion 26, a thirdannular lug 29 is arranged. Thethird lug 29 has the same radial distance to themiddle axis 20 as thesecond lug 28. Beside thethird lug 29, the connector 1 comprises afurther section 31 that has a larger radial distance to themiddle axis 20 than thethird protrusion 26. Theretainer ring 8 has an inner diameter that may be larger than an outer diameter of the second andthird protrusions retainer ring 8 is basically fixed to the connector 1 by a force-fit connection. - In the embodiment in that the
interface element 7 is to be installed by the jointer and is molded from a thermoplastic or any other rigid material, the design should incorporate means to insert into the metal ring. Thefigures 5 to 10 show several embodiments for theinterface element 7 to provide the possibility for mounting theinterface element 7 to theretainer ring 8. -
Figure 5 shows a schematic side view of aninterface element 7 that is embodied as an open ring with anopening 32. In the shown embodiment, 10 % of the ring may be open. Theinterface element 7 is made of a flexible material or a thermoplastic material like e.g. PP,PVC, PA or the like so that it can be bent to a larger diameter for mounting on the connector 1. Theinterface element 7 offigure 5 is flexible enough to be mostly elastically deformed during the insertion in theretainer ring 8. Theinterface element 7 may be made of softer thermoplastic materials, in the example soft PVC or of higher Shore hardness elastomers such as EPDM or silicones. -
Figure 6 shows a further embodiment with aninterface element 7 in the shape of an open ring, wherein opposite to theopening 32 of the ring, aflexible section 33 is arranged. Theflexible section 33 may be attained by a smaller diameter of the cross-section of theinterface element 7 or by providing recesses in theinterface element 7 or by a more flexible material that is arranged in theflexible section 33. Theinterface element 7 offigure 6 is also embodied as an open ring but has a weakening preferably opposite to theopening 32 of the ring for allowing a better flexing of theinterface element 7. Theflexible section 33 may be embodied as a flexible thin wall element that allows for elastic flexing with little force. After the flexing, theinterface element 7 firmly sits in theretainer ring 8. -
Figure 7 shows a further embodiment of aninterface element 7 with threeelements 35 that are flexibly connected byflexible parts 34. Eachelement 35 has the shape of a part of a ring. Theflexible parts 34 may be made of the same material as theelements 35 for example as a flexible thin wall. In a further embodiment, theflexible parts 34 may be embodied as spring elements that are fixed to opposite ends of theelements 35. In the shown embodiment, there are threeelements 35 that are connected viaflexible parts 34. Depending on the used embodiment, there may be less ormore elements 35 that are connected together byflexible parts 34.

Theinterface element 7 offigure 8 can comprise two ormore elements 35 that may be made of rigid material and that are linked to each other by a pin-and-hole arrangement as a fixingelement 36. When the pins are inserted into the holes, the assembly is small enough in diameter to fit into theretainer ring 8. After the mounting of theinterface element 7 in theretainer ring 8, theelements 35 are moved apart from each other, preferably still having thepins 39 being inserted into theholes 40 to a certain extent to avoid theelements 35 from falling off theretainer ring 8. -
Figure 9 shows a third embodiment of aninterface element 7 that comprises three partially ring-shapedelements 35 that may be press-fit to the connector 1 and/or press-fit to theretainer ring 8. The embodiment of theinterface element 7 shown infigure 9 comprises two or moreindividual elements 35. Theelements 35 are force-fit to theretainer ring 8 so that theelements 35 can be mounted on the inside of theretainer ring 8 without falling off. The force-fit can be achieved e. g. by little protrusions in thesecond recess 16 that is arranged on an annular outer face of theelements 35 or by having a smaller size of the second recess than the width of theretainer ring 8. -
Figure 10 shows a further embodiment of anannular interface element 7 that is made of two parts that are fixed by a press-fit connection and that has an open ring structure. The embodiment of theinterface element 7 shown infigure 10 is made of two or more mainlyrigid parts figure 8 . Again, theseparts section 5 of the connector 1. An option for ease of handling is an additional force-fit ofpins 39 inholes 40 of theparts -
Figure 11 shows in a schematic side view aretainer ring 8. -
Figure 12 shows in a schematic view aninterface element 7 that is mounted on aretainer ring 8. Theinterface element 7 is embodied as an open ring as shown infigure 5 . -
