Description

[0001] The invention relates to an easy-to-assemble embodiment of an electrical angled connector.

[0002] Various designs of angled connectors are already known in the prior art. However, the assembly of these angled connectors, especially the connection of the cables to the contact elements of the angled connector, is usually very cumbersome, as the contact elements are difficult to access due to the shape of the angled connector.

[0003] The prior art in the present technical field is disclosed in documents DE 101 06 153 A1 (based on claim 1 as a general concept), DE 94 14 613 U1, EP 0 411 239 B1, DE 12 02 857 A, DE 10 2004 033 738 A1 and DE 10 2017 110 385 A1 (subsequently published).

[0004] The invention is therefore based on the objective of overcoming the aforementioned disadvantages and providing an easy-to-assemble angle connector whose contact elements are easily accessible during assembly, thereby making the entire assembly process simpler than with other angle connectors.

[0005] The problem is solved according to the invention by an electrical angled connector with the features according to claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.

[0006] According to the invention, an electrical angled connector with a two-part housing, each part of which can be connected to the other via a corresponding connecting section, is therefore proposed.The housing, comprising a first housing part extending in a first direction from a mounting side to its connection section, and a second housing part extending in a second direction oriented transversely to the first direction from its connection section to a plug-in side section, also comprises an adapter piece for insertion in the second direction into the first housing part, and a contact body for receiving at least one contact element, wherein the adapter piece, in its fully inserted and mounted state in the first housing part, extends at least partially into the second housing part, and wherein the contact body is detachably held on the adapter piece by means of connecting means and is fixed against axial displacement in the second direction by means of the connecting means.This ensures easy mounting of cables to the contact body, and since this can be inserted separately into the housing, the mounting point is easily accessible.

[0007] For insertion mounting, the adapter piece has at least one profiled extension which can be inserted into a corresponding groove in the first housing part. The reverse of this principle, i.e., the extension on the housing part and the groove on the adapter piece, is also possible. Sliding surfaces can also be formed between the profiled extension and the corresponding groove, so that the pairing forms a sliding bearing.

[0008] It is advantageous if the adapter piece has at least a partial C-shaped contour into which it receives the contact body. This allows the two wing-shaped arms of the adapter piece to curve around the contact body, thus holding it in position radially to its longitudinal axis until final assembly.

[0009] According to the invention, the connecting means between the contact body and the adapter piece are designed as a groove on the contact body and, corresponding to the groove, as a projection on the adapter piece that engages in the groove. This fixes the contact body in its position until final assembly.

[0010] A non-inventive embodiment is characterized in that the groove on the adapter piece is designed as an upwardly open groove. The groove can thus follow the entire C-shape of the adapter piece or be formed only in part of the C-shape; it is also possible for the groove to be designed as a through-hole, i.e., to completely penetrate the wall of the C-shaped adapter piece. Corresponding to the design of the groove on the adapter piece, the projection on the contact body can completely encircle the outer surface of the contact body or be formed only partially on the outer surface.

[0011] According to the invention, it is further provided that in the design of the groove on the contact body, an embodiment is provided in which the groove on the contact body is formed in a ring-shaped circumferential manner.

[0012] Furthermore, an advantageous embodiment exists if at least one coding groove or coding rib extends from one end face of the contact body in the second direction and is provided at at least one position on the outer surface of the contact body, wherein a contact body counterpart has at least one corresponding coding rib or coding groove. It is the case that a coding rib is always formed between two coding grooves. Such coding prevents faulty connections, which increases ease of handling and operational reliability.

[0013] One possible embodiment provides that the adapter piece serves as a counterpart to the contact body. This means that the adapter piece also has at least one corresponding coding groove or coding rib to those on the contact body. If the contact body has several coding grooves or coding ribs, but the adapter piece only has one, the adapter piece can thereby be adjusted and fixed in its rotational position relative to the contact body.

[0014] An advantageous embodiment exists when a two-part cable management channel is formed from the mounting side to the plug-in side section, wherein a first cable management channel section extends through the first housing part from the mounting side to its connection section, and a second cable management channel section extends through the second housing part from its connection section towards the plug-in side section of the second housing part. The cable management channel serves both to accommodate and guide cables. Cable guidance can be provided by an internal contour of the housing walls, which facilitates the insertion and routing of the cables through the housing.

[0015] It is positive and therefore advantageous if a first seal is provided between the contact body and the second housing part. This protects the inside of the housing from dust, other dirt, and, up to a certain pressure limit, also from fluids.

[0016] It is also advantageous if a second seal is provided between the first and second housing parts; preferably, the seal is installed in a groove-shaped receptacle on the outer surface of the first housing part. This ensures that the housing is also sealed at its joint against dust, dirt, and, up to a certain pressure limit, against fluids.

[0017] It is advantageous, especially for harsh environments, if the two-part housing incorporates metallic material. This makes it more durable and resistant.

[0018] Other advantageous embodiments of the invention are characterized in the dependent claims or are described in more detail below together with the description of the preferred embodiment of the invention with reference to the figures. The figures show: Fig. 1 Overall view of the angle connector; Fig. 2 View of the angled connector without the second housing part; Fig. 3 Partial view of the angle connector; Fig. 4 View of the second housing part; Fig. 5 Rotated view of the second housing part; Fig. 6.

Also shown are the contact body 40 and the first direction X and the second direction Y.

[0021] Fig. Figure 2 shows an angled connector 1 without the housing part 20. This allows the first housing part 10, its mounting side 10a, its connecting section 10b, and the contact body 40, as well as the cable guide part 11, to be seen. Due to the absence of the second housing part 20, the adapter piece 30, the connecting element 60 on the contact body side, and the first direction X are also visible.

[0022] Fig. Figure 3 shows an angled connector as in Fig. 2, however, the contact body 40 is also missing, which means that the adapter-side connecting element 61 is also visible.

[0023] Fig. Figure 4 shows only the second housing part 20, which reveals its connecting section 20b, its plug-side section 20a and cable routing channel 21.

[0024] Fig. 5 is one, compared to Fig. 4. Rotated view, which looks like Fig. 4 represents the housing part 20 and its plug-side section 20a.

[0025] In Fig. Figure 6 shows an embodiment of a contact body 40 and its connecting means 60.

[0026] Fig. 7 shows one, opposite Fig. 6, View rotated 180° around the longitudinal axis of the contact body 40, whereby its connecting means 60 and the underside of the contact body 40 are still visible.

[0027] In Fig. Figure 8 shows an alternative embodiment of a contact body 40 and its connecting means 60, which is designed as a circumferential groove.

[0028] Fig. 9 shows one, opposite Fig. 8, View rotated 180° around the longitudinal axis of the contact body 40, whereby its connecting means 60 and the underside of the contact body 40 are still visible.

[0029] Fig. Figures 10 to 12 each show a sectional view of the angled connector 1, with the contact body 40 assuming a different angular position in each view due to the engagement of a different coding groove. The views thus show the first housing part 10 with its mounting side 10a, as well as a section through the adapter 30 and through the contact body 40. The connecting elements 60 and 61 and the first direction X are also visible.

[0030] Fig.Figures 13 to 15 each show a sectional view of an alternative form of the angled connector 1, in which the contact body 40 assumes a different angular position due to the engagement of a different coding groove. The views thus show the first housing part 10 with its mounting side 10a, as well as a section through the adapter 30 and through the contact body 40. The connecting elements 60 and 61 and the first direction X are also visible.
