Description

The disclosure relates to a connector extension for attaching at least one line to a plug element of a plug connection and a plug extension arrangement and a plug system with such a plug extension. Furthermore, the disclosure relates to a method for attaching at least one line to a plug element of a plug connection. The plug element may be a so-called SFP plug element (SFP), for example an SFP, QSFP, a QSFP-DD, an OSFP or the like.

Such tabs are known from the prior art and are used for example in network connections as electrical and / or optical connectors. More specifically, such connector elements serve to connect a line, such as a data or signal line with a high data transmission rate, to a printed circuit board. For this purpose, the data or signal line to be connected is known to be led into this via a rear end wall of the plug element. In addition, a line outlet and / or a section of the plug element are often encapsulated in sections for securely attaching the line to the plug element.

Due to the limited space, the smallest possible design of Steckerelmenten is sought. In addition, for example, SFP connector elements are standardized by standards among other things, in terms of their structure and their geometric dimensions. An SFP connector element and a QSFP connector element are in the document WO 2013/030093 A2 disclosed.

In today's applications, however, the lines to be connected by means of plug elements always reach larger cross sections, each exceeding the maximum dimensions of the plug elements, more precisely their rear end wall. Also, a plurality of lines are often to be connected by means of a single plug element, wherein the plurality of lines also have a common overall cross-section, which exceeds the maximum dimensions of the plug elements, more precisely, the rear end wall thereof. In these cases, it is no longer possible to ensure a secure connection of the line or lines to the plug element in a conventional manner by crimping or encapsulation.

There is thus a need to enable the attachment of cables and / or cable bundles with large (total) cross sections on a plug element, for example on an SFP plug element. A large (overall) cross section may mean that this (overall) cross section exceeds a maximum outer dimension of the plug element or a rear housing section of the plug element in at least one dimension (height and / or width), i. its maximum height or width extension, if the at least one line is in a non-loaded or undeformed state.

For this purpose, a plug extension with the features of claim 1 is proposed. Further, a Steckererweiterungsanorndung with the features of claim 10, a plug system with the features of claim 11 and a method with the features of claim 13 is proposed. Further embodiments will become apparent from the dependent claims 2 to 9, 12 and 14 and the following description.

According to a first aspect, a plug extension for attaching at least one line to a plug element of a plug connection, for example to an SFP plug element or the like, is provided. The connector extension comprises a longitudinally extending hollow base body having at a first end an attachment portion for mechanically connecting the base body to the connector element, for example with one of the at least one line facing back housing portion (the so-called "backshell") of the male member. The hollow base body is configured to at least partially receive the at least one line via a second end opposite the first end in order to bring a free end of the at least one line into conductive connection with a contact element of the plug element.

More specifically, the hollow body of the connector extension at its first end to the plug member facing outlet opening and at its second end facing away from the plug member outlet opening, wherein the at least one conduit inserted through the inlet opening into the hollow body and the outlet opening from the hollow body herausführbar and inserted into the plug element.

The main body of the connector extension is dimensioned and shaped so that it is in frictional connection with the at least one at least partially received therein line over its inner peripheral surface and this partially elastically deformed. It is understood that for such a non-positive connection and elastic deformation, the maximum dimensions of the inner cross section of the base body in at least one dimension of height and / or width is less than that maximum dimension of the (overall) cross section of the at least one at least partially housed in the body line in the corresponding dimension, when the at least one line is in a non-loaded or undeformed state. Thus, the hollow body over its inner peripheral surface from the outside exert a force on the at least one at least partially housed therein line, making them by the elastic deformation in their dimensions to the maximum dimensions in the dimensions height and / or width of the inner cross section of the body of the connector extension is limited. Over time, retardation can also cause a plastic deformation of the at least one line accommodated at least in sections in the connector extension.

Accordingly, it is possible by means of the above plug extension, lines and / or trunk groups with large (total) cross-sections securely on a connector element, for example, to an SFP connector element to install.

In one embodiment, the plug extension in a lateral surface of the main body may have at least one opening, via which an injection molding compound can be introduced into the hollow base body from outside, around a cable jacket of the at least partially duct received in the base body by means of the injection molding compound with the inner peripheral surface of the hollow Connect basic body. By such an adhesive bonding of the at least one at least partially accommodated in the connector extension line to the main body of the connector extension strain relief of the line can be achieved. The at least one opening can be arranged in an upper, a lower and / or a lateral lateral surface of the main body. The at least one opening may, for example, be arranged in a region of the lateral surface near the first end and / or near the second end of the basic body. For example, two opposing openings may be formed in the lateral surface of the base body. It is understood, however, that the base body can also have more than two openings for introducing injection molding compound.

According to a development of the plug extension, the base body, at least in a region facing the plug element, can have a maximum height extent which is equal to or less than the height extent of an end section of the plug element facing the plug extension. In addition or alternatively, the base body, at least in the region facing the plug element, can have a maximum width extension which is equal to or smaller than the width extension of the end extension of the plug element facing the plug extension. The plug extension which faces the end portion of the plug element can be the rear-side housing section, that is to say the so-called "backshell", of the plug element. For example, the entire base body in all areas have a maximum height and / or width extension, which is equal to or smaller than the height or width extension of the connector extension facing end portion of the plug member.

In an embodiment, the base body of the connector extension may include a first base portion having a substantially rectangular cross-section extending from the attachment portion toward the second end of the body. Furthermore, the main body of the plug extension can comprise a second base region adjoining the first base region and having a substantially T-shaped cross section which extends as far as the second end of the main body. Accordingly, the base body in the T-shaped second base region may have a first width and a second width, wherein the second width is greater than the first width. The first width may be substantially equal to the width of the first base region. The T-shaped second base region may be continuous in a connection region, i. without sharp edges, go over to the first base area. Due to the T-shaped cross-section of the second base region, the inlet opening of the main body can also have a T-shaped cross section, whereby a simplified introduction of the at least one line into the main body can be made possible by the second width, which is greater than the first width , Even though the at least one line is accommodated, cavities can also be formed in the base body by the larger second width, into which sheath material of the at least one line can extend or into which sheath material of the at least one line can be pressed due to the deformation. Injection molding compound may also accumulate in the cavities for connecting the at least one line to the inner peripheral surface of the base body.

It is understood that the base body may have base regions with other cross-sectional geometries in alternative embodiments. Also, the main body may have more than a first and a second base portion.

In a further development, the attachment portion of the base body may be sleeve-shaped. Also, the attachment portion may be at least partially complementary to a receiving recess formed in the plug member. For example, the attachment portion have a rectangular cross section or a cylindrical shape. The receiving recess may be a conventional cylindrical or other opening formed in the rear-side housing portion of the plug member.

According to one embodiment, at least one material projection may be formed on the inner peripheral surface of the base body, for example in the region of the second end of the base body, which extends inwardly into the hollow base body. This at least one material projection may form an undercut for the at least one at least partially accommodated in the connector extension line, more specifically for the jacket of the line. This allows a strain relief can be achieved, whereby the at least one line can be held in the hollow body. The inner peripheral surface of the base body may also have a plurality of material projections which extend inwardly into the hollow base body. For example, the plurality of material projections may be formed on opposite surface portions of the inner peripheral surface of the main body.

In a further development, the plug extension may comprise a substantially dimensionally stable housing which forms the hollow body. In this way it can be ensured that the basic body does not deform by receiving the at least one line with a large (overall) cross section. Thus, it can be ensured by means of a dimensionally stable housing that the original maximum height and width extension of the connector extension simultaneously corresponds to the maximum height and width extension of the arrangement also plug extension and at least one at least partially housed therein line with large (total) cross-section.

Alternatively, the housing forming the main body may be at least slightly flexible or flexible.

In one embodiment, the connector extension may be integrally formed. For example, the above-described first base region and the second base region (as well as the connection region) may be integrated.

The connector extension can be a die-cast, metallic component. At least the main body of the connector extension can be a die-cast, metallic component. This allows the connector extension to have desired EMC characteristics. Alternatively, the connector extension can be made of plastic.

Another aspect relates to a Steckererweiterungsanorndung with a connector extension of the type described above and at least one at least partially recorded in the connector extension line, such as a data or signal line with high data transmission rate.

A further aspect relates to a plug system comprising a plug element of a plug connection, for example an SFP plug element, and a plug extension of the type described above.

Also, the connector system may comprise at least one at least partially accommodated in the connector extension line, such as a data or signal line with a high data transmission rate.

Another aspect relates to a method for attaching at least one line to a plug element of a plug connection, for example by means of a plug extension of the type described above.

In the following, specific details are set forth without limitation to provide a thorough understanding of the present disclosure. However, it will be apparent to those skilled in the art that the present disclosure may be used in other embodiments that may differ from the details set forth below.

The 1 to 3 show an embodiment of a connector extension 10 in a perspective view, in a plan view and in a rear view. The connector extension 10 includes a longitudinally extending hollow body 12 with a first end 14 and one the first end 14 longitudinally opposite second end 16 , At the second end 16 is an entrance opening 18 trained while the first end 14 an outlet opening 20 having.

At the first end 14 of the basic body 12 is a mounting section 22 educated. In the in the 1 to 3 shown embodiment, this mounting portion 22 sleeve-shaped and has a substantially rectangular cross-section. The maximum height and width extension of the attachment section 22 is less than the maximum height and width extension of the rest of the body 12 , The attachment section 22 is with a circumferential edge 24 provided, which forms an undercut and thereby can support the connection to an associated connector element. For example, an encapsulation or a portion of the plug element engage behind the edge in the connected state.

The main body 12 has in its lateral surface two oppositely arranged openings 26 . 28 on, about which an injection molding compound from the outside in the hollow basic body 12 is injectable. In the embodiment of the 1 to 3 are the openings 26 . 28 in an upper lateral surface and in a lower lateral surface near the second end 16 of the basic body 12 arranged. The openings 26 . 28 are formed here circular. It is understood, however, that the openings 26 . 28 in alternative embodiments may have any other geometric shape, which may be adapted, for example, to an injection nozzle of an injection device.

Like from the 1 to 3 can also be seen, comprises the main body 12 the connector extension 10 a first base area 30 arising from the attachment section 22 towards the second end 16 of the basic body 12 extends. The first base area 30 has a substantially rectangular cross-section. The main body 12 also includes a second base area 32 that is starting from the second end 16 of the basic body 12 towards the first base area 30 extends, ie in the direction of the first end 14 , The second base region has a substantially T-shaped cross-section. The T-shaped second base area 32 has a first width B1 and a second width B2 on, with the second width B2 larger than the first width B1 is. The first width B1 of the T-shaped second base region corresponds in the embodiment shown, the width of the first base region 30 that over the entire first base area 30 is essentially the same. In a connection area 34 of the basic body 12 go the T-shaped second base area 32 continuous, ie without sharp edges, in the first base area 30 over. In this way it can be prevented that a line accommodated in the basic body (not shown here) is damaged.

The main body 12 the connector extension 10 has on its inner peripheral surface 36 two opposing material protrusions 38 . 40 on that in the 1 and 3 are shown. The material projections 38 . 40 are each at a front edge at the second end 16 of the basic body 12 trained and protrude inward into the body 12 in front. material projections 38 . 40 each form an undercut for a male in the connector extension line, whereby a strain relief can be achieved to the line in the hollow body 12 to keep.

In the embodiment shown, the plug extension is formed in one piece and in the form of a dimensionally stable component. The connector extension here is a die-cast, metallic component.

In the figures described below are comparable or identical and equivalent components and features with the same reference numerals as in FIGS 1 to 3 Provided. The components and features that are related to the 4 to 6 are not described again similar in their training and function the corresponding components and features according to the 1 to 3 ,

The 4 to 6 show a further embodiment of a connector extension 10 in a perspective view, in a side view and in a sectional view. This further embodiment of the 4 to 6 is essentially similar to the previously explained, in the 1 to 3 shown embodiment. For this reason, in the following, in particular, the differences of the further embodiment with respect to the embodiment described above will be discussed.

In contrast to the connector extension described above are according to the connector extension 10 the 4 to 6 the openings 27 . 29 for injecting injection molding material not near the second end 16 of the basic body 12 but in the first base area 30 near the attachment section 22 seconded, ie near the first end 14 of the basic body 12 , However, the openings are far enough from the mounting portion 22 spaced that they are not covered in a state attached to a plug member state of a portion of the male member or an encapsulation.

Another difference from the plug extension described above are the openings 27 . 29 the connector extension 10 the 4 to 6 also not formed in an upper and a lower lateral surface, but are opposite to each other in lateral lateral surfaces of the base body 12 arranged.

Furthermore, the openings have 27 . 29 the connector extension 10 the 4 to 6 a smaller diameter than the openings 26 . 28 the connector extension 10 the 1 to 3 on.

It is understood that a connector extension both one or both of the in the 1 to 3 as well as one or both of the in the 4 to 6 may include openings shown.

In the 7 to 9 is an embodiment of a plug system with a plug element 50 , a connector extension 10 according to 4 and a trunk group 60 shown in a perspective view and in two different sectional views.

The plug element 50 Here is a QSFP-DD plug element (QSFP-DD - quad small form-factor pluggable double density), which is a known locking mechanism with an actuator 52 having. SFP, QSFP, QSFP-DD and OSFP connector elements are known to those skilled in the art (see, for example, the above referenced document WO 2013/030093 A2 ), which is why here on a detailed description of the components and features of the plug element shown by way of example 50 is waived.

As in particular from the sectional view in 8th can be seen, are the mounting portion 22 the connector extension 10 and a portion of a back side housing portion 54 of the plug element 50 , the so-called "backshell", formed complementary to each other. As a result, the rear housing section engage behind 54 and the attachment section 22 each other, making them in a connection area 70 mechanically firmly connected to each other. At the same time by such at least partially complementary design of the rear housing section 54 and the attachment section 22 a planned orientation of the connector extension 10 and the plug element 50 achieved, which also adjacent to each other openings of the connector extension 10 and the plug element 50 are aligned together.

The connector extension 10 serves to attach or tie the lines 62 . 64 comprehensive trunk group 60 to the plug element 50 , It is understood that only a single line or a trunk group of more than two lines can be connected by means of the connector extension to the connector element.

For attaching or connecting the cable bundle 60 to the plug element 50 , is the trunk group 60 through the entrance opening 18 in the hollow body 12 the connector extension 10 insertable and over the outlet opening 20 from the hollow body 12 herausführbar and in the plug element 50 insertable. The conductive connection of a contactable free end of the cable bundle 60 with a contact element of the plug element 50 is realized in a conventional manner, as is known for example from SFP or QSFP plug elements, and is therefore not shown in detail in the figures. The introduction of the cable bundle 60 in the connector extension 10 can be done before or after mechanically connecting the connector extension 10 with the plug element 50 respectively.

In the illustrated trunk group 60 it is a cable bundle with a large overall cross-section, the maximum external dimension of the plug element 50 or the rear housing section 54 of the plug element 50 exceeds the height and width in at least one of the dimensions when the trunk group 60 is in a non-loaded or undeformed state. Because the plug extension 10 in its construction and its dimensions to the plug element to be coupled therewith 50 is adapted, the maximum dimensions of an inner cross section of the hollow body 12 in at least one dimension of height and / or width is less than the maximum dimension of the total cross section of the wire bundle 60 in the appropriate dimension, as long as this is undeformed.

By receiving the trunk group 60 in the main body 12 the connector extension 10 , this stands over its inner peripheral surface 36 at several sections in frictional connection with the sectionally received therein trunking. Due to the external force application of the dimensionally stable body 12 on the trunk group 60 , this is partially elastically deformed, causing the trunking 60 or each of the lines 62 . 64 in its / their dimensions to the maximum dimensions in the dimensions height and width of the inner cross section of the body 12 the connector extension 10 is limited. This is in particular in the sectional view according to 9 to recognize. Here is also to see that the height and the width extension of the wire bundle 60 by the maximum height and the width extent of the inner cross section of the substantially rectangular first base region 30 of the basic body 12 is limited.

As the main body 12 the connector extension 10 has a maximum height and width extension equal to or less than the maximum height or width extension of the rear end portion 54 of the plug element 50 is that allows with the plug element 50 couplable connector extension 10 Thus, even cables and / or cable bundles with large (total) cross-sections quickly and securely attach to the plug element.

The inside in the hollow body 12 extending into material protrusions 38 . 40 stand, such as in 9 can be seen, also in contact with the trunk group 60 , This becomes the trunk group 60 in this contact area even more elastically deformed than in the other areas of the body 12 , Behind the material protrusions 38 . 40 the trunk group expands 60 or its jacket material again, which is why the material projections 38 . 40 each represent an undercut for the trunk group. As a result, a strain relief is achieved, which is the trunking 60 in addition to the other traction between the trunk group 60 and the body 12 in the hollow body 12 holds.

As further in 9 is shown, arise due to the different geometries of the trunking cross section and the inner cross sections of the body 12 between the trunk group 60 and the inner peripheral surface 36 of the basic body 12 several cavities, of which for reasons of clarity only one example by the reference numeral 42 is provided. In the cavities 42 can over the openings 27 . 29 Injection molding compound are introduced to the jacket of the cable bundle 60 with the inner peripheral surface 36 of the basic body 12 connect and provide for a further strain relief.
