- Figure 14 shows the connector of Figure 11 in a side view, in a fully assembled state of the housing assembly.
- a connector 1 for example an electrical connector
- a housing assembly 2 and a cable 3 for example an electrical cable leading into the housing assembly 2
- the embodiments each show an angled connector, but this is not to be understood as limiting the invention.
- the invention is also fundamentally suitable for use with non-angled connectors.
- the connector 1 shown as an example in Figures 1 to 5 can have various known connector components.
- a contact element 4 is indicated as an example in the figures (e.g. an outer conductor contact element or an inner conductor contact element).
- the housing assembly 2 has at least a first housing part 5 and a second housing part 6, which can be mechanically connected to one another, as indicated in Figures 1 and 2.
- the housing parts 5, 6 are already connected to one another, whereby in their connected state they jointly form a cable feedthrough 7 through which the cable 3 can be introduced into an interior 8 (cf. Figure 1) of the housing assembly 2 or the connector 1.
- the housing parts 5, 6 form respective circumferential sections Ui, U2 (cf. Figures 1 and 8) of the cable feedthrough 7.
- the two housing parts 5, 6 can be locked together.
- the first housing part 5 has at least one locking arm 9 that is at least partially spring-elastic and has a locking receptacle 10 that can be engaged by a corresponding locking hook 11 of the second housing part 6 (see, for example, the assembled state in Figure 3).
- the connection between the first housing part 5 and the second housing part 6 can also be fixed in another way, for example by screwing, a force fit or even by a material connection.
- a cable sealing element 12 (cf. Figures 6 to 10) for the cable 3 is accommodated in the cable duct 7 formed by the two housing parts 5, 6 in order to provide a seal between the cable sheath 13 and the inner sheath surface 14 of the housing parts 5, 6 forming the cable duct 7 (cf. Figure 1).
- the cable sealing element 12 is formed in one piece together with a housing sealing element 15 by a common sealing body 16, which is shown in Figures 6 and 7 in a variant that is to be understood as an example only in a single representation. In principle, a multi-part design and therefore also a separate cable sealing element 12 is also possible.
- the cable sealing element 12 is primarily tubular or sleeve-shaped, with the outer surface 17 of the cable sealing element 12 preferably running over the entire surface along the inner surface 14 of the housing parts 5, 6 in the area of the cable feedthrough 7 when the housing assembly 2 is completely assembled.
- the cable sealing element 12 is completely closed or ring-shaped and has a central opening 18 (see Figure 6) for the passage of the cable 3.
- the housing sealing element 15 already mentioned is designed to ensure a seal between the housing parts 5, 6 and also forms a circumferentially closed course with a further central opening 19 (see Figure 6).
- the housing sealing element 15 is - like the housing parts 5, 6 - angled, so that a first section 20 of the housing sealing element 15 (a "U-shaped” section) or a first section 20 of the central opening 19 extend in a first plane Ei and a second section 21 (again "U-shaped” section) of the housing sealing element 15 or a second section 21 of the central opening 19 extend in a second plane E2, as indicated in Figure 7.
- the planes Ei, E2 are preferably arranged orthogonally to one another, as can be clearly seen, for example, from Figures 2 and 7.
- a transition section 22 can be provided between the two sections 20, 21 in order to enable a uniform and gentle, for example rounded, transition between the two sections 20, 21.
- the sealing body 16 or the housing sealing element 15 and/or the cable sealing element 12 can be fixed in at least one of the housing parts 5, 6, in particular connected in a materially bonded manner to one of the housing parts 5, 6.
- the sealing body 16 or the housing sealing element 15 can be injected into the first housing part 5 during production. In this way, the manufacturing costs can be reduced and the assembly process simplified.
- the proposed housing assembly 2 also has a housing securing part 23 which at least partially encloses the housing parts 5, 6 at least in the area of the cable feedthrough 7 and in particular in the area of the cable sealing element 12 in order to fix the housing parts 5, 6 to one another.
- the housing securing part 23 can be displaceable on at least one of the housing parts 5, 6 up to a final assembly position (see Figures 4 and 5). This displacement preferably takes place along a feed direction Z for the cable (see Figures 1 and 3), but can also deviate from the feed direction Z of the cable 3 if necessary.
- the housing securing part 23 fixes the housing parts 5, 6 to one another and thus increases the mechanical stability of the housing assembly 2 against transverse loads in the area of the cable feedthrough 7, so that the tightness is maintained even under adverse application conditions.
- the housing assembly direction G (see Figure 2) for connecting the first housing part 5 to the second housing part 6 and the securing assembly direction S (see Figure 3) for mounting the housing securing part 23 on the housing parts 5, 6 preferably differ from one another.
- the housing assembly direction G and the securing assembly direction S run orthogonally to one another.
- this is not absolutely necessary - the securing assembly direction S can if necessary, also run in the same direction as the housing mounting direction G - especially if the housing securing part 23 is not completely closed in the circumferential direction.
- a guide in particular a linear guide, can be provided, in particular in the area of the housing parts 5, 6 in which the cable feedthrough 7 is formed.
- the guide functions for the assembly of the housing securing part 23 and the fixing function of the housing securing part 23 can complement each other.
- Figures 8 to 10 show three exemplary variants of housing securing parts 23 based on a front view of the cable feedthrough 7 in an assembled state.
- a particularly robust stabilization of the cable feedthrough 7 can be achieved, for example, if the housing securing part 23 completely encloses the housing parts 5, 6 in the area of the cable feedthrough 7, as indicated in Figure 8.
- a linear guide can thus also be provided.
- the situation is similar with the housing securing part 23 according to Figure 9, which merely clamps the housing parts 5, 6 in the area of the cable feedthrough 7.
- a support surface 24 of the housing securing part 23 rests on a counter support surface 25 of the housing parts 5, 6 forming the cable feedthrough 7.
- two opposite side legs 26 extend, which clamp the second housing part 6 with their end sections. Again, this can simultaneously form a linear guide.
- FIG. 10 Another type of clamping with integrated linear guide is indicated in Figure 10.
- rail guide systems 27 are formed on both sides. Accordingly, the side legs 26 have elongated webs 28 running in the securing assembly direction S, which are guided in corresponding grooves 29 of the housing parts 5, 6.
- the housing securing part 23 can be connected to at least one of the housing parts 5, 6 in a captive manner.
- the housing securing part 23 can be locked to the first housing part 5 and to the second housing part 6.
- the housing securing part 23 has a locking arm 30 that is elastic at least in sections and has a locking receptacle 31 (see Figure 1), which can be gripped behind by a locking hook 32 of the respective housing part 5, 6 (see Figures 1 and 2).
- a fixation between the housing securing part 23 and at least one of the housing parts 5, 6 can be carried out in any way, for example by pressing or screwing (not shown).
- the housing assembly 2 is assembled by connecting the first housing part 5 to the second housing part 6, so that the housing parts 5, 6 form respective circumferential sections Ui, U2 of the common cable feedthrough 7, through which the cable 3 is guided into the interior 8 of the connector 1.
- the housing securing part 23 can then be assembled so that the housing parts 5, 6 are at least partially enclosed, at least in the area of the cable feedthrough 7, in order to fix the housing parts 5, 6 to one another.
- At least one of the housing parts 5, 6 in the exemplary embodiments, the first housing part 5) and the housing securing part 23 are connected to one another in one piece in a pre-assembly state or in a non-assembled state via at least one connecting web 33.
- the principle will first be explained in more detail using the exemplary embodiment of Figures 11 to 14.
- FIGs 11 to 14 show a fundamentally similar embodiment of the invention, as already explained with reference to Figures 1 to 10, which is why functionally identical elements are not described again in detail.
- the cable 3 and the cable sealing element 12 or the sealing body 16 are hidden in Figures 11 to 14.
- the housing assembly 2 again has a first housing part 5 and a second housing part 6, which together form a cable feedthrough 7 in the assembled state, in which a cable sealing element 12 for the cable 3 is accommodated.
- a connecting web 33 is provided, which is designed in the manner of a film hinge.
- the connecting web 33 has a very thin wall thickness, at least in sections, and is therefore sufficiently elastic to enable a pivoting movement between the housing securing part 32 and the first housing part 5. This pivoting movement alone can, if necessary, reach the end position of the housing securing part 32 on the first housing part 5. If necessary, however, it can also be provided that the connecting web 33 breaks off in a defined manner during the pivoting movement and/or during a subsequent axial movement.
- the connecting web 33 can therefore also be designed as a predetermined breaking point.
- This connecting web 33 enables the first housing part 5 and the housing securing part 23 to be manufactured together during assembly, in particular by a common plastic injection molding process, whereby the first housing part 5 and the housing securing part 23 can be assembled individually before or during final assembly by breaking the predetermined breaking point or by a movement guided over the connecting web 33.
- the Housing securing part 23 and the housing parts 5, 6 are therefore made of the same material, in particular of a plastic.
- the housing securing part 23 which in the embodiment of Figures 11 and 14 is held in the pre-assembled state and via the connecting web 33, is rotated or pivoted relative to the final assembly position and is held axially offset (along the feed direction Z for the cable 3), is first pivoted (see Figures 12 and 13) and then moved along the securing assembly direction S into the final assembly position (see Figures 13 and 14).
- the connecting web 33 can optionally be designed to break at any time during the assembly process, in particular during the axial displacement along the securing assembly direction S (indicated in Figure 13).
- exactly one connecting web 33 is provided for connecting the housing securing part 23 to the first housing part 5.
- several connecting webs 33 can also be provided, for example several connecting webs 33 that are distributed around the circumference of the cable duct 7 and, for example, equidistantly, as indicated in Figures 1 to 5 and in particular in Figures 8 to 10.
- the housing securing part 23 is only axially offset along the feed direction Z or securing assembly direction S compared to the final assembly state, but not twisted or pivoted.
- the connecting web 33 can also be designed to be sufficiently elastic or deformable to enable the housing securing part 23 to move into the final assembly position without breaking off. However, this is less preferred.
