Definitions
- the invention relates to a connector housing arrangement, in particular for an electrical connector, comprising a housing component with at least one receiving chamber for a contact element and at least one securing element mountable in the housing component in order to axially secure the contact element in an assembled state within the receiving chamber along a longitudinal axis of the receiving chamber, according to the preamble of claim 1.
- the invention also relates to a connector, in particular an electrical connector, comprising the connector housing arrangement and the contact element.
- Connectors are known to be used to transmit electrical power, electrical data signals and/or optical data signals to other connectors or to corresponding mating connectors.
- a connector or mating connector can be a plug, a circuit board connector, a built-in connector, a socket, a coupler, a capacitive coupler or an adapter.
- the term "connector” or “mating connector” used in the context of the invention represents all variants.
- a connector or mating connector in the context of the invention can be an electrical and/or optical connector or mating connector.
- the transmission of electrical power or an electrical/optical data signal between a connector and a corresponding mating connector is achieved by contacting a contact element of the connector and an associated mating contact element of the mating connector.
- the individual contact element In order to achieve reliable electrical or optical contact, the individual contact element must generally be correctly positioned both axially and laterally within the connector housing. The correct positioning and alignment of the contact element is usually mechanically secured by at least one securing element. As a rule, axial movement of the contact element against its mounting direction is limited so that the contact element does not emerge from the associated receiving chamber of the housing component at the back or cable side when subjected to tensile stress or during a plugging process.
- a plug connection must be able to withstand high loads, such as mechanical loads, and must remain closed in a defined manner so that the electrical connection cannot be accidentally broken, for example during operation of a vehicle. Ensuring safety is a priority, particularly in autonomous vehicle operation and for driver assistance systems.
- the securing element is usually fed axially or laterally to the contact element inserted in a receiving chamber. If a tensile force then acts on the electrical or optical cable connected to the contact element, the securing element limits the axial displacement of the securing element either by a direct mechanical connection to the contact element (also known as an "independent secondary lock” or “Independent Secondary Lock” (ISL)) or indirectly by blocking a separate primary securing element (also known as a "dependent secondary lock” or “Primary Locking Reinforcement (PLR)).
- ISL Independent Secondary Lock
- PLR Primary Locking Reinforcement
- the securing element usually abuts axially against an end stop on the housing component. However, with particularly large mechanical loads or tensile forces, it can happen that the securing element bends transversely to the tensile force and/or is moved out of its securing position, thereby releasing the contact element.
- CN 206 148 708 U relates to a connector housing with contact elements that can be fixed in receiving chambers by means of a securing element.
- EP 1 113 535 A2 relates to securing elements of a connector for securing contact elements in contact chambers.
- US 5 772 478 A relates to an electrical connector housing in which a secondary locking mechanism is provided in order to secure contact elements within a housing body.
- CN 205 376 850 U relates to a connector with an insulating housing with a locking receptacle into which a securing element for locking a contact element can be inserted.
- the object of the present invention is to provide a connector housing arrangement with a securing element for a contact element, which is able to reliably secure the contact element even under particularly high mechanical loads, preferably with simple assembly and economical manufacture.
- the present invention is also based on the object of providing a connector whose contact element is reliably secured in the connector housing arrangement even under particularly high mechanical loads, in particular tensile loads, while preferably being easy to assemble and economical to manufacture.
- a connector housing arrangement for a connector is proposed.
- the connector housing arrangement according to the invention can be particularly advantageously suitable for an electrical connector or for an optical connector.
- the connector housing arrangement according to the invention has a housing component with at least one receiving chamber for a contact element (in particular for an electrical or optical contact element).
- the connector housing assembly further comprises a securing element mountable in the housing component to axially secure the contact element in an assembled state within the receiving chamber along a longitudinal axis of the receiving chamber.
- the proposed securing element is thus able to secure the contact element in the correct position and/or orientation when it is accommodated in the receiving chamber.
- Such securing elements are also known as "secondary securing".
- the securing element is preferably a component that is independent of the housing component and that can be inserted into the housing component at least in sections during connector assembly to attach or secure the contact element.
- the securing element can be fed in particular laterally and/or axially in the direction of the longitudinal axis of the housing component or the receiving chamber.
- the securing element is preferably a rigid component or an inelastic component. In this way, the securing element can reliably secure the contact element even under high mechanical loads.
- the housing component has at least one cable-side end stop for the securing element in order to limit an axial movement of the securing element along the longitudinal axis of the receiving chamber at least in the case of a tensile load acting on the contact element.
- the safety element can be connected or mechanically coupled to the contact element in the assembled state, so that the safety element is released in the event of an axial cable pull or in the event of a the contact element is axially carried by the tensile load acting on it.
- the securing element can then axially abut the housing component or the connector housing and thereby limit the movement of the contact element.
- the housing component has at least one first blocking means in order to limit a movement of the securing element, at least in the case of tensile loading, in at least one spatial direction running at an angle to the longitudinal axis of the receiving chamber.
- the securing element cannot leave the securing position in which the contact element is secured against pulling out, even in the event of excessive tensile loading.
- the securing element can thus advantageously be secured in at least one further spatial direction.
- the securing element is designed to mechanically directly axially secure the contact element in the state mounted in the housing component.
- the securing element can in particular form a positive connection with the contact element in order to prevent axial displacement and/or rotation of the contact element within the receiving chamber of the housing component.

- the securing element can therefore encompass or clasp the contact element at least in sections or engage in the contact element at least in sections in order to bring about a direct movement coupling.
- a positive connection between the securing element and the contact element for securing the contact element can be created in particular by an orthogonal (relative to the longitudinal axis of the receiving chamber) insertion of the securing element into the housing component and thus, for example, by an orthogonal insertion of a locking element (e.g. a partially annular rib) of the securing element into a groove of the contact element.

- the shape of the securing element itself and the shape of the contact element can also cause mutual latching, for example if the securing element is designed in the shape of a clamp and is elastic at least in some areas, so that the clamp can temporarily spread out on the contact element during assembly.
- the contact element can, for example, have the ring-shaped groove already mentioned above or another recess in the outer surface into which the securing element can engage in the assembled state in such a way that the securing element is not only axially coupled to the contact element in terms of movement, but also latches to the contact element.
- any type of fastening of the securing element to the contact element can be provided (positive locking, non-positive locking and/or material locking), so that the securing element can be moved together with the contact element, particularly in the event of an axial movement, for example a tensile load, and/or is secured against unintentional disassembly against the mounting direction of the securing element.
- the securing element is designed to axially secure the contact element in the state mounted in the housing component indirectly by blocking a separate primary securing element.
- the separate primary securing element for the contact element can in particular be a primary locking hook.
- This primary locking hook can be blocked in the securing position of the securing element in such a way that an unlocking movement is prevented.
- the housing component preferably an inner wall or an outer wall of the housing component, can be shaped in such a way, in particular in a region which directly adjoins a feed opening for the securing element in the direction of the cable, that it forms both an axial stop and a lateral blocking for the axially deflected securing element.

- the receiving chamber can be a completely enclosed chamber, but can also be accessible laterally if necessary.
- the cable-side end stop of the housing component can be formed in particular by a stop surface within a feed opening for the securing element. In principle, however, the cable-side end stop can be formed in any way in the housing component or by the housing component, for example also outside a corresponding feed opening.
- the cable-side end stop can also be formed by a separate component that is connected to the housing component. Preferably, however, the cable-side end stop is formed integrally or monolithically with the housing component.
- a plug-side end stop can also be provided to limit axial movement of the securing element along the longitudinal axis of the receiving chamber in the direction of the plug-side end of the securing element.
- the plug-side end stop can also be, for example, a stop surface within the above-mentioned feed opening or another stop surface or another stop.
- the feed opening can in particular be designed as a slot in the housing component. However, it can also be a window-shaped opening in the housing component or another opening.
- the present invention is particularly advantageously suitable for use with a clamp-shaped secondary securing device, since the solution according to the invention can prevent, on the one hand, escape against the mounting direction and, on the other hand, optionally also prevent lateral spreading of the clamp.

- the one-piece variant is preferred.
- the blocking of the contact element can advantageously be achieved by the interaction of the first blocking means and the second blocking means.
- the second blocking means has a course that is complementary to the first blocking means. However, this is not absolutely necessary.
- the release position can preferably be a mechanically unloaded, preferably force-free mounting position of the securing element in the housing component.
- the securing position can preferably be a mechanically loaded position (in particular due to the tensile load) of the securing element in the housing component, which differs from the release position.
- a transverse extension of the feed opening can be greater than a transverse extension of the securing element.
- such mechanical play can enable the movement of the securing element between the release position and the securing position.
- a "release position" of the securing element is understood to mean a position in which the securing element can be removed from the housing component without causing any damage, preferably without tools, in particular in the opposite direction in which it was mounted.
- the release position is preferably a pre-securing position in which the securing element can generally initially still be moved in the direction of the cable-side end of the connector housing arrangement.
- the securing element can be introduced into the housing component, in particular by means of a translational movement, into the position mounted in the housing component, in particular the said "release position".
- a translational movement can be provided for this purpose, particularly preferably an exclusively translational movement orthogonal to the longitudinal axis.
- the at least one movement of the securing element extending at an angle to the longitudinal axis of the receiving chamber limited.
- the movement of the securing element by the at least one first blocking means in the at least one spatial direction running at an angle to the longitudinal axis of the receiving chamber is therefore preferably only limited in the securing position.

It can also be provided additionally or alternatively that the surface vector of the second blocking surface has a component opposite to the plug-in direction or opposite to the mounting direction of the securing element in the release position (i.e. a component in the "dismantling direction" of the securing element).
- the second blocking surface can have a surface vector that is opposite to the surface vector of the first blocking surface.
- first blocking surface and the second blocking surface are sometimes referred to collectively as “blocking surfaces” below.
- the first blocking surface can preferably be formed within the feed opening of the housing component.
- the second blocking surface can preferably be formed on an outer surface of the securing element, in particular on an outer surface of the at least one securing leg.

- the blocking surfaces only have the first and second directional components, the movement of the securing element opposite to the mounting direction can advantageously be limited. If, however, the blocking surfaces only have the first and third directional components, the movement of the securing element in a direction away from the longitudinal axis of the receiving chamber (i.e. spreading of the securing element) can be blocked.
- the first blocking surface can be aligned orthogonally to the longitudinal axis of the receiving chamber and/or to the mounting direction for the securing element, for example. Preferably, however, an angle other than 90° is provided. In the case of an oblique alignment of the blocking surfaces at an angle other than 90°, the blocking surfaces have all three of the aforementioned directional components.
- Another advantage of an angular alignment other than 90° can be that the force for securing the locking element in the locking position becomes stronger the more the tensile load on the contact element increases. Due to the slope or angular alignment of the first blocking surfaces, the locking element is preferably pressed closer to the contact element as the tensile load increases. As the cable tension increases, the locking element becomes increasingly wedged.
- the first blocking means and the second blocking means are each formed in a complementary oblique manner.
- the blocking surfaces can preferably be flat or at least essentially flat or level.
- the blocking surfaces can, however, also have a curved or bent shape, in particular a mutually complementary convex/concave shape.
- a stepped or multi-stepped shape of the blocking surfaces can also be provided.
- the first blocking means limits the movement of the securing element in two mutually orthogonal spatial directions, which each run at an angle, preferably orthogonally, to the longitudinal axis of the receiving chamber.
- the securing element is blocked along or against the mounting direction so that it cannot escape from the feed opening in the event of a tensile load acting on the contact element.
- the first blocking surface is therefore preferably aligned at an angle to the mounting direction for the securing element, in particular orthogonal to it.
- the securing element is blocked transversely to its mounting direction in a direction away from the longitudinal axis of the receiving chamber so that the securing element cannot spread laterally in the event of a tensile load acting on the contact element.
- a combination of blocking in or against the mounting direction, as well as transversely to the mounting direction i.e. a combination of the two variants above).
- the housing component and the securing element form a mutual thread-like connection.
- the thread-like connection preferably extends along the longitudinal axis of the receiving chamber in such a way that the securing element rotates relative to the housing component in the course of an axial displacement along the longitudinal axis of the receiving chamber.
- an inner wall of the housing component and an outer surface of the securing element can be formed complementarily to one another at least in sections in order to form the thread-like connection.
- the securing element can be set in rotation relative to the longitudinal axis of the connector or the receiving chamber.
- the rotation of the securing element can also limit its movement in at least one spatial direction that is at an angle to the longitudinal axis of the receiving chamber.
- the rotation of the securing element causes an immediate fixation of the securing element to the contact element in that the securing element, which has been rotated from its initial position, at least partially engages behind the contact element, for example in that the opening of the clamp-like securing element is rotated relative to the mounting direction of the securing element; and/or b)
- the rotation of the securing element causes an immediate fixation of the securing element to the housing component in that the securing element, which has been rotated from its initial position, at least partially engages behind the housing component, for example in that the securing element is displaced at least partially radially and/or axially under a projection of the housing component during the rotation or is moved at least partially radially and/or axially into a receptacle of the housing component; and/or c)
- the thread-like connection forms less than two complete threads, preferably only one complete thread or less, preferably only half a thread or less, particularly preferably only a quarter of a thread or even less.
- the housing component has a plurality of receiving chambers running parallel to one another for respective contact elements.

- the securing element can be designed to secure at least two of the contact elements together (in particular at least two contact elements accommodated in immediately adjacent receiving chambers).
- the invention also relates to a connector, in particular an electrical connector or an optical connector, comprising a connector housing arrangement according to the above and following embodiments, as well as the contact element.
- the contact element can be accommodated in the receiving chamber and the securing element can be mounted in the housing component for axially securing the contact element.
- a connector with increased contact holding force can be provided in an advantageous manner by preventing the securing element from moving out of its securing position, for example by springing out. In this way, the holding force of the contact element coupled to the securing element within the connector housing or a housing component of the connector can be increased. Complex geometries of the connector housing for surrounding or overbuilding the securing element can be dispensed with, whereby the installation space for the connector can be minimized despite high mechanical stability or holding force.

- the securing element 7 can thus, for example, strike the inside of the feed opening 12 and, due to the direct or indirect connection with the contact element 3, also limit the movement of the contact element 3.
- the securing element 7 In order to prevent, according to the invention, the securing element 7 from no longer being able to maintain its securing position within the receiving chamber 6 when the tensile load Fz is further increased, for example by the securing element 7 being partially lifted out of the feed opening 12 again against its mounting direction M (cf. Figure 1) or spreading out laterally to the longitudinal axis L of the receiving chamber 6, it is proposed to form at least one first blocking means 14 on the housing component 5 in order to limit a movement of the securing element 7 at least in the case of the tensile load Fz in at least one spatial direction x, y running at an angle to the longitudinal axis L of the receiving chamber 6 (cf. in particular the coordinate system shown in Figure 1).
- the securing element 7 has a respective second blocking means 15 on each of the securing legs 8, which is designed to mechanically contact the first blocking means 14 of the housing component 5 in order to limit the movement of the securing element 7 accordingly.
- the second blocking means 15 and the first blocking means 14 preferably each have a complementary course.
- the first blocking means 14 can be a first blocking surface 16, which is formed in the housing component 5 on a recess or a projection, in particular in the feed opening 12 for the securing element 7.
- the second blocking means 15 can be a complementary, second blocking surface 17.
- the blocking surfaces 16, 17 are aligned at an angle to the mounting direction M of the securing element 7 or to the course of the feed opening 12.
- an angle a other than 90° has proven to be suitable (see Figure 3) in order to ensure centering of the securing element 7 in the case of tensile load and also to continuously increase the retaining force for the securing element 7 with a continuously increasing tensile load Fz.
- the blocking surfaces 16, 17 of the first blocking means 14 and the second blocking means 15 are arranged at an angle to the longitudinal axis L of the receiving chamber 6, preferably at an angle ß other than 90° (see Figure 8).
- the inclined blocking surfaces 16, 17 can prevent the clamp-like securing element 7 from spreading out of its securing position in a second spatial direction x.
- FIG. 12 to 16 A further embodiment of the invention is shown in Figures 12 to 16.
- the housing component 5 and the securing element 7 form a mutual, thread-like connection 18 which extends in the direction of the longitudinal axis L of the receiving chamber 6 in such a way that the securing element 7 rotates relative to the housing component 5 in the course of an axial displacement along the longitudinal axis L of the receiving chamber 6.
- the twisted state in the case of tensile load is shown in Figures 14 and 16.
- the rotation of the securing element 7 can thus also be used to directly fix the securing element 7 to the contact element 3 (and/or to the housing component 5, as will be explained below with reference to Figure 17).
- the rotation can cause the opening of the securing element 7 to be rotated in relation to its mounting direction M, so that the securing element 7 engages behind the contact element 3, which can lead to a movement limitation according to the invention (see Figures 15 and 16).
- Figure 17 also shows a detail of two variants that can be implemented independently of one another or in combination for a securing element 7 that is twisted in the loaded state (the contact element 3 is hidden in each case), in which the securing element 7 is directly fixed or secured to the housing component 5 in that the securing element 7 and the housing component 5 engage behind one another axially and/or radially at least in sections due to the twisting.
- the securing element 7 can be moved under a first blocking surface 16 of a first blocking means 14, as can also be clearly seen when comparing Figures 13 and 14.
- Respective securing edges 19 of the securing element 7 and/or housing component 5 can also be used accordingly to limit the movement of the securing element 7 in at least one spatial direction x, y that runs at an angle to the longitudinal axis L of the receiving chamber 6 when the securing element 7 is twisted from its initial position.
- the locking can be achieved by exploiting the simultaneous axial and radial displacement of the thread.
- the securing element 7 can also be limited by at least one first blocking means 14 of the housing component 5 in many other ways within the scope of the invention.
