EP3785334B1 - Connector part with a shielding sleeve - Google Patents

Description

The invention relates to a connector part according to the preamble of claim 1 and a method for producing a connector part.

Such a connector part comprises an electrically conductive shielding sleeve, a plug-in section arranged on the shielding sleeve for plugging connection to an associated mating connector part, at least one electrical contact element arranged in or on the plug-in section and a plastic housing part at least partially enclosing the shielding sleeve.

A connector part of this type can be designed, for example, as a so-called round connector in which the plug-in section has an essentially cylindrical shape and can be connected to a correspondingly shaped, complementary mating connector part. Such a circular connector can be used advantageously for data, sensor signal and power transmission in an industrial environment, for example. From the U.S. 2015/332809 A1 a connector part according to the preamble of claim 1 is known.

The shielding sleeve is made from an electrically conductive material and is used in particular to shield signals transmitted via the connector part. The plastic housing part can be formed directly on the shielding sleeve, for example by overmolding, and thus partially encloses the shielding sleeve in such a way that line cores of an electrical line connected to the connector part are fixed relative to the shielding sleeve and are thus fixed to the connector part. By means of such a plastic housing part formed by overmoulding, not only the shielding sleeve but also, for example, a connection area for stranded wires of line wires can be enclosed inside the connector, so that contact elements of the connector part are not mounted floating inside the connector part, but are held in position by the plastic housing part will.

In general, it is desirable for such a connector part to maintain a predefined degree of protection and to be adequately moisture-proof. For this purpose it is necessary to seal a transition between the plastic housing part and the shielding sleeve so that moisture cannot penetrate through any capillary gap between the plastic housing part and the shielding sleeve into the interior of the Connector part can reach. If the plastic housing part is formed by overmoulding the shielding sleeve, such a seal may be difficult.

the DE 10 2010 036 324 A1 describes a cable and an injection-moulded component arranged thereon. The molded component is sealed off from the cable by a sealing element.

At one from the DE 10 2013 205 493 A1 known connector is a shield sealed to a conductor.

In the EP 2 112 721 A1 describes a plug-in connection, in which a compression ring is arranged in front of one end of the cable insulation under the overmolding, which encloses the cable insulation and is mechanically pressed from at least two sides, so that the compression ring inelastically deforms the cable insulation and the underlying braided shield, the wire insulation and the cable wire permanently pinching constricted.

From the U.S. 2010/0184318 A1 a connector with a sealing element in the form of an O-ring is known.

The object of the present invention is to provide a connector part and a method for producing a connector part which, with a simple structure and simple production, enable reliable sealing of the plastic housing part with respect to the shielding sleeve.

This object is solved by an object with the features of claim 1.

Accordingly, the connector part comprises a pressing element which is arranged on the shielding sleeve and is connected to the plastic housing part and has a receiving device, and a sealing element which is arranged in the receiving device of the pressing element and which is in sealing contact with the shielding sleeve to seal a transition between the plastic housing part and the shielding sleeve. wherein the plastic housing part is manufactured by overmoulding a section of the shielding sleeve.

The plastic housing part is thus formed by overmolding on the shielding sleeve.

In order to enable a transition between the plastic housing part and the shielding sleeve to be sealed, a sealing assembly consisting of the pressing element and the sealing element is used, which is arranged on the shielding sleeve and is thereby connected to the plastic housing part. The sealing element is used here to seal the transition between the plastic housing part and the shielding sleeve and is in sealing contact with the shielding sleeve. A preload is provided on the sealing element via the pressing element, in that the sealing element is pressed against the shielding sleeve via the pressing element and thereby compressed, so that a seal is provided due to the pressing contact of the sealing element on the shielding sleeve.

Due to the fact that the sealing element is held on the shielding sleeve via the pressing element (separate from the plastic housing part but connected to the plastic housing part, for example by surface contact or a material connection) and is pressed against the shielding sleeve via the pressing element, the compression of the sealing element is Sealing against the shield sleeve set via the pressing element. The sealing effect of the sealing element is thus independent of the plastic housing part, in particular an action of the plastic housing part on the sealing element. This makes it possible to set a favorable seal via the pressing element in order to then form the plastic housing part, for example by overmolding on the shielding sleeve.

The pressing element is connected to the plastic housing part. In one embodiment, this can take place in that the pressing element forms a bond with the plastic housing part, for example by the pressing element being connected to the plastic housing part in a material-to-material, non-positive or positive-locking manner.

A material connection between the pressing element and the plastic housing part can be produced, for example, by the fact that when the shielding sleeve is overmolded with the material of the plastic housing part, the plastic housing part is also injection molded onto the pressing element (which is then already attached to the shielding sleeve), so that the injection molding creates a material connection Bond is made between the pressing element and the plastic housing part.

When molding the plastic housing part on the shielding sleeve, in one embodiment, the pressing element can also be overmoulded, so that the pressing element is completely or partially surrounded by the plastic housing part. In this case, the plastic housing part covers the assembly of the pressing element and the sealing element on the outside and thus encloses the pressing element and the sealing element.

In another embodiment, however, it is also conceivable and possible for the plastic housing part to be molded onto a front surface of a body of the pressing element and thus form a flat bond with the pressing element.

In yet another embodiment, it is conceivable and possible that the plastic housing part is in contact with the pressing element, but there is no material connection between the plastic housing part and the pressing element consists. For example, the pressing element can be held in position on the shielding sleeve by engaging in a locking groove of the shielding sleeve such that the pressing element is in contact with the plastic housing part and is connected to the plastic housing part.

In one embodiment, the shielding sleeve has a shaft section which is formed on an end of the shielding sleeve which is remote from the plug-in section. The shielding sleeve can, for example, have a basic cylindrical shape--in particular if the connector part is designed as a circular connector--and the shaft section of the shielding sleeve and the plug-in section can also be cylindrical in shape accordingly. The plastic housing part is arranged on the shank section, for example in that the shank section is at least partially overmoulded with the material of the plastic housing part.

In one embodiment, the pressing element is ring-shaped and is arranged on the shaft section of the shielding sleeve in such a way that the pressing element extends around the shaft section. In this case, the pressing element is designed as a ring element and is attached to the (in particular cylindrically shaped) shank section of the shielding sleeve, so that the shank section reaches through the pressing element. By engaging in a locking groove on the shank section, the pressing element can be held in position on the shank section, which facilitates the assembly of the pressing element together with the sealing element on the shielding sleeve and also enables the pressing element and the sealing element to be fixed in a precise position relative to the shielding sleeve.

If the pressing element is designed as a ring element, the locking groove preferably extends circumferentially around the shielding sleeve (for example around the shaft section on which the pressing element is arranged) and thus holds the pressing element in position on the shielding sleeve with a positive fit.

If the pressing element is designed as a ring element, the sealing element is preferably also designed in the shape of a ring and is shaped, for example, in the manner of an O-ring. The sealing element is accommodated in the receptacle of the pressing element and extends circumferentially in the receptacle. The sealing element is arranged on the shank section of the shielding sleeve in such a way that the shank section extends through the sealing element and is in pressing, sealing contact with the sealing element.

In one embodiment, the pressing element has a body which is in contact with the shielding sleeve with a contact surface. The body can, for example, engage in the latching groove on the shank section of the shielding sleeve, so that the pressing element is fixed in a form-fitting manner on the shank section. There is contact between the pressing element and the shaft section via the contact surface.

The sealing element is preferably designed such that in an initial state before the assembly consisting of the pressing element and the sealing element is attached to the shielding sleeve, the sealing element projects beyond the contact surface of the body of the pressing element. When the pressing element together with the sealing element is placed on the shielding sleeve, interaction with the shielding sleeve results in compression on the sealing element and thus in a pressing contact of the sealing element on the shielding sleeve for reliable, moisture-tight sealing of a transition between the plastic housing part and the shielding sleeve .

In one configuration, the receiving device forms an undercut for receiving the sealing element. The sealing element is accommodated in the receiving device and is held in a form-fitting manner due to the shape in the manner of an undercut and is thus secured against axial slipping. The sealing element can therefore not easily slip out of the receiving device axially to the shielding sleeve—in particular axially to the (cylindrical) shaft section on which the pressing element is arranged together with the sealing element—so that the sealing element is held in position relative to the pressing element.

In one embodiment, the sealing element is manufactured as a separate element from the pressing element and is inserted into the receiving device of the pressing element. In this case, the sealing element can be designed as an O-ring, for example, and is accommodated in the receiving device in such a way that in the mounted position the sealing element is held in compressed, pressing contact with the shielding sleeve via the pressing element.

In this case, the pressing element can be made, for example, from a comparatively hard plastic, for example a thermoplastic material. The sealing element, on the other hand, is made of a comparatively soft material, for example a rubber material or a soft plastic material, for example an elastomer, and can therefore be compressed for reliable, sealing contact with the shielding sleeve.

In another embodiment, the pressing element and the sealing element can be manufactured by plastic injection molding using a two-component injection molding technology. In this embodiment, the sealing element is not present separately from the pressing element after production, but is produced together with the pressing element by plastic injection molding. In this case, the pressing element is formed by a comparatively hard plastic component, for example a thermoplastic material, while the sealing element consists of a soft component, for example an elastomer.

In one embodiment, the sealing element has a bead section that is accommodated in the receiving device of the pressing element. If the sealing element is designed as an annular element, the bead section, which is for example circular or oval in its cross section, extends, for example, around the shaft section of the shielding sleeve. The sealing element is preferably in sealing contact with the shielding sleeve via the bead section.

In one embodiment, a surface section extends from the bead section—essentially perpendicularly to the outside of the shaft section—and rests, for example, on an end face of the pressing element. The surface section can, for example, extend to the peripheral outside of the body of the pressing element, which can facilitate the manufacture, in particular the injection molding of the sealing element when manufacturing using a two-component injection molding technology.

The object is also achieved by a method for producing a connector part according to the type described above. In the method, the pressing element is attached together with the sealing element to the shielding sleeve, and the plastic housing part is molded on the shielding sleeve by overmolding.

The advantages and advantageous configurations described above also apply analogously to the method.

Figures 1 to 3A , 3B show an exemplary embodiment of a connector part 1 in the form of a circular connector which can be connected to an associated mating connector part 3 along a plug-in direction E.

The connector part 1 has a shielding sleeve 10 on which a screw element 11 for connecting and fixing the connector part 1 to the mating connector part 3 is arranged. The screw element 11 can be rotated on the shielding sleeve 10 in order in this way to produce a firm, resilient and vibration-resistant connection of the connector part 1 with the mating connector part 3 .

The shielding sleeve 10, which is made from an electrically conductive material, in particular a metal material, forms a plug-in section 100 which encloses a plug-in face 12 with a plurality of electrical contact elements 120. The plug-in connector part 1 can be plugged into the mating connector part 3 along the plug-in direction E via the plug-in section 100 in order to establish an electrical connection between the plug-in connector part 1 and the mating connector part 3 in this way.

The connector part 1 is connected to an electrical line 2, which has a plurality of line cores that make electrical contact with the contact elements 120 and is inserted at an end remote from the plug-in section 100 via a cylindrical shaft section 101 of the shielding sleeve 10 into the interior of the connector part 1.

How out Figure 2B As can be seen, a plastic housing part 15 is arranged on the shielding sleeve 10 (namely on the shaft section 101 of the shielding sleeve 10 facing away from the plug-in section 100), which partially encloses the shaft section 101 and the electrical conductors of the cable 2 inserted into the shaft section 101 and thereby closes the electrical conductors of the shielding sleeve 10 is fixed. The plastic housing part 15 is molded onto the shaft section 101 of the shielding sleeve 10 by means of plastic injection molding and thus forms a firm bond with the shielding sleeve 10.

The connector part 1 in the form of the circular connector is used for data, signal and/or power transmission and in particular enables a reliable, vibration-resistant, resilient connection of an electrical line 2 to an associated electrical assembly. It is desirable here to maintain a defined degree of protection on the connector part 1, which in particular also requires adequate moisture tightness. In particular, it should be avoided that moisture can get into the interior of the connector part 1 to prevent impairment of an electrical connection.

In particular, this makes it necessary to seal a transition between the plastic housing part 15 and the shielding sleeve 10 . For this reason, the connector part 1 has a sealing assembly consisting of a pressing element 13 and a sealing element 14, which is attached to the shaft section 101 of the shielding sleeve 10 and serves to prevent moisture from penetrating through a capillary gap between the plastic housing part 15 and the shielding sleeve 10, in particular the shank portion 101 to prevent.

The pressing element 13 is designed as a ring element and has, as shown in the views according to FIG Figures 3A, 3B As can be seen, a body 130 which bears against the shaft section 101 with a contact surface 131 . In the area of the contact surface 131, the body 130 engages in a latching groove 102 (see Fig Figure 2B ) on the peripheral outside of the shank section 101, so that the pressing element 13 is positively fixed to the shank section 101 and in particular cannot slip axially on the shank section 101.

A receiving device 132 in the form of an annular recess for receiving the sealing element 14 is formed in the body 130 . The receiving device 132 forms an undercut in the form of a concave depression, which causes the sealing element 14 to be held in the receiving device 132 in a form-fitting manner and, in particular, cannot slip out of the receiving device 32 axially along the shaft section 101 .

In the illustrated embodiment, the assembly consisting of the pressing element 13 and the sealing element 14 is produced using a two-component injection molding technology by means of plastic injection molding. The assembly is thus manufactured in an injection molding tool using two different plastic components, namely a hard component for forming the pressing element 13 and a soft component for forming the sealing element 14. A thermoplastic can be used as the hard component, for example. The soft component can be formed by an elastomer, for example.

As per the sectional view Figure 3A As can be seen, the sealing element 14 has an annular circumferential bead section 141 with which the sealing element 14 rests in the receiving device 132 of the pressing element 13 . A ring-shaped peripheral surface section 140 abutting an end face 133 of the body 130 of the pressing element 13 extends from the bead section 141 to a peripheral outer side of the body 130, so that the end face 133 of the pressing element 13 is covered by the surface section 140. Such a configuration of the sealing element 14 can in particular enable simple manufacture by injecting the sealing element 14 onto the pressing element 13 in an injection molding tool.

For assembly, the assembly consisting of the pressing element 13 and the sealing element 14 is attached to the shaft section 101 of the shielding sleeve 10 in one work step until the pressing element 13 engages with the latching groove 102 formed on the shaft section 101 . Because, as per the sectional view Figure 3B As can be seen, in an initial state the beaded section 141 of the sealing element 14 protrudes radially inwards beyond the contact surface 131 of the pressing element 13, when the pressing element 13 and the sealing element 14 are applied to the shaft section 101 the sealing element 14 is compressed in the area of its beaded section 141 and thus reaches in pressing, sealing contact with the peripheral lateral surface of the shank section 101. The sealing element 14 thus seals against the shank section 101.

Then, with the electrical line 2 connected to the connector part 1, the plastic housing part 15 is formed directly on the shielding sleeve 10, in that the electrical line 2 and the shaft section 101 are at least partially overmoulded with the material of the plastic housing part 15, so that the electrical line 2 is attached of the shielding sleeve 10 is fixed.

In doing so, as is shown in the sectional view Figure 2B As can be seen, the assembly consisting of the pressing element 13 and the sealing element 14 is overmoulded with the material of the plastic housing part 15, so that the plastic housing part 15 forms a bond with the pressing element 13 and thus the assembly consisting of the pressing element 13 and the sealing element 14 forms the plastic housing part 15 is fixed.

Because the sealing element 14 extends annularly around the shaft section 101, a transition between the plastic housing part 15 and 15 is in this way sealed to the shaft portion 101 in a moisture-tight manner. In particular, moisture can no longer pass through a capillary gap between the plastic housing part 15 and the shaft section 101 past the sealing element 14 into the interior of the connector part.

At the in Figures 4 to 6A , 6B In the exemplary embodiment illustrated, a sealing element 14 is designed as a ring-shaped element in the form of an O-ring that is separate from a pressing element 13, as is shown in particular in FIG Figure 6B is evident. The sealing element 14 is inserted into a receiving device 132 of the pressing element 13 and is held positively in the receiving device 132 via an undercut formed on the receiving device 132 (in the form of a concave depression in the region of the receiving device 132).

In this case, the pressing element 13 is produced as a plastic part by injection molding from a comparatively hard plastic material, in particular a thermoplastic material.

For assembly, the assembly consisting of the pressing element 13 and the sealing element 14 is again attached to the shaft section 101 of the (for the exemplary embodiment according to Figures 1 to 3A , 3B structurally identical) shielding sleeve 10 is attached in order to then overmold the shaft section 101 together with an electrical line 2 connected to the connector part 1 with the material of the plastic housing part 15 and in this way to form the plastic housing part 15 on the shielding sleeve 10. The assembly consisting of the pressing element 13 and the sealing element 14 is also overmoulded, as can be seen from the sectional view according to FIG Figure 5B can be seen, so that the assembly is fixed to the shielding sleeve 10 and a transition between the plastic housing part 15 and the shaft section 101 is sealed by the sealing element 14 in a moisture-tight manner.

7 shows a compared to the embodiment according to Figures 1 to 3A , 3B modified exemplary embodiment in that the plastic housing part 15 does not completely enclose the pressing element 13 after the shank section 101 of the shielding sleeve 10 has been overmolded on the outside, but terminates at a rear end face 150 of the pressing element 13 facing away from the plug-in section 100. In this case, too, the material of the plastic housing part 15 preferably forms a (materially bonded) bond with the pressing element 13 during injection molding, so that a connection is created between the plastic housing part 15 and the pressing element 13 .

Analog shows 8 a modification of the embodiment according to Figures 4 to 6A , 6B . Again, the material of the plastic housing part 15 does not completely enclose the pressing element 13 towards the outside, but is flush with an end face 150 of the pressing element 13 .

In the embodiments according to Figures 7 and 8 the pressing element 13 can also be used as a seal for an injection molding tool when the shaft section 101 of the shielding sleeve 10 is overmolded. In this case, during injection molding, the injection molding tool can, for example, bear against the pressing element 13 on the outside, so that the material of the plastic housing part 15 can be molded onto the pressing element 13 within the injection molding tool.

It is conceivable in particular in the case of the exemplary embodiments according to FIG Figures 7 and 8 also that when the plastic housing part 15 is injected, the material of the plastic housing part 15 does not form a material bond with the pressing element 13 . The fact that the body 130 of the pressing element 13 rests in the latching groove 102 of the shank section 101 means that the pressing element 13 is held in position relative to the plastic housing part 15, so that in this way a connection between the plastic housing part 15 and the pressing element 13 is established through surface contact.

The idea on which the invention is based is not limited to the exemplary embodiments described above, but can also be implemented in a completely different manner.

A connector part of the type described here can advantageously be designed as a circular connector. However, this is not mandatory. In principle, the invention can also be used with other plug connectors.

By using the pressing element, compression is provided on the sealing element, which reliably seals a transition between the plastic housing part and the shielding sleeve. The compression on the sealing element is set by the pressing element and is basically independent of the plastic housing part. In this respect, the shaping of the plastic housing part on the shielding sleeve and the seal are decoupled from one another, which on the one hand enables a cheap, simple shaping of the plastic housing part on the shielding sleeve and on the other hand a reliable seal.
