Description

Technical area

The present invention relates to a conductor holder for fixing at least one electrical and / or optical line in a motor vehicle. In particular, the conductor holder is also suitable for fastening a flat conductor rail, which serves as a supply or ground conductor. Furthermore, the invention relates to a line arrangement with such a line holder and a recorded therein line.

State of the art

Conduit holders which are suitable for fastening a line or a wiring harness in a motor vehicle are already known from the prior art. Such a line holder is mainly used to fix the line or lines to a body or interior trim part, so that the laying path of the line is fixed and no rattling noises or the like may arise. Frequently, these holding parts are already attached to the line at the line manufacturer or assembler, and the line or set of lines in this configuration are delivered to an automobile manufacturer in which the line set is then laid in the motor vehicle and fastened thereto.

An exemplary conductor holder is from the DE 10 2016 114 734 A1 known. The conductor holder has a holder base and at least one attachment flange formed on the holder base for attachment to the vehicle. According to the invention, the conductor holder also has at least two oppositely curved spring legs, which extend substantially perpendicularly away from the holder base and form a line receiving section between them. In this case, the spring legs are curved in such a way that the line receiving section tapers in a direction away from the holder base to a tapering section. In addition, at least one of the spring legs in or adjacent to the taper portion on a side facing the wire receiving portion at least one hook member for engaging with the conduit. For stronger or heavier lines, however, it would be desirable that the line receiving portion can be closed with a lid in order to hold the line as firmly as possible.

A line holder according to the preamble of claim 1 is for example from the DE 10 2016 107 080 A1 known. Accordingly, the line holder has a lower holder part and a hinged thereto via a hinge holder cover, which is pivotable relative to the lower holder part between an open position and a closed position and forms at least in the closed position together with the lower holder part an intermediate receiving space for the line. The latching of the holder cover on the holder base is effected via an outer latching tab and a latching projection, which can already be achieved by pulling the latching tab over the latching projection. In contrast, a more robust locking would be desirable.

Description of the invention

The object of the invention is therefore to provide a particularly robust latched way of attaching a line using structurally simple means possible.

The object is solved by the subject matters of the independent claims. Advantageous developments of the invention are specified in the dependent claims, the description and the accompanying figures.

A conductor holder according to the invention is suitable for fastening at least one electrical and / or optical line in a motor vehicle. Thus, one or more lines can be attached as round conductors individually or as a set of lines, also bundled, via the line holder in or on the motor vehicle. But it can also be one or more flat conductor rails, which are dimensionally stable or solid in contrast to ductile lines, are attached via the conductor holder to the motor vehicle.

The conductor holder has a holder lower part and a holder cover hinged thereto via a hinge, which is pivotable relative to the holder lower part between an open position and a closed position and forms at least in the closed position together with the holder lower part an intermediate receiving space for the line. The receiving space may e.g. be formed pot-shaped by lateral walls of the holder base, wherein the holder cover spans the receiving space, so that it encloses the line in its circumferential direction and remain open only the front sides for passing the line.

According to the invention, the line holder has at least one latching hook either on its lower holder part or on its holder lid. The latching hook is arranged and / or shaped so that it has in the closed position of the holder cover a first stop surface, which faces away from a pivoting direction of the holder cover to reach the open position. At this first stop surface, a first counter stop of the If the closed lid of the holder is to be opened, attach it to the lower part of the holder or the holder lid. In other words, the first abutment surface and the first counter stop surface form an undercut or an undercut, which must first be lifted before the holder cover can be opened. In addition, the line holder also has a second abutment surface which is directed away from the first abutment surface on a side of the latching hook facing away from the first abutment surface in such a way that an applied, ie actually applied or fictitious, compressive force on the second abutment surface is the first Stop surface in the direction of the closed position urges. In this second abutment surface may strike a second counter stop surface to further reinforce the undercut of the first abutment surface with the first counter stop surface. Thus, the one abutment surface forms a kind of counter-holder for the respective other abutment surface of the latching hook.

As a result, the line holder secures itself in the closed position of the holder cover and forms a robust locking, so that even comparatively heavy lines are securely held. In particular, flat conductor rails can be securely attached to the motor vehicle. But the conductor holder also allows easy installation, since the two stop surfaces of the latching hook serve each other as a counter-holder for locking the latching hook. As a result, the line holder also has a particularly small size, since no separate counter-holder is necessary, which also leaves more space for receiving the line.

A particularly advantageous development of the invention provides that the latching hook is formed on the lower housing part. The latching hook preferably extends perpendicularly away from a base surface of the holder lower part and the first stopper surface facing the base surface runs parallel thereto. The base may also be slightly wedge-shaped to be either undercut to accommodate higher tensile forces or to perform the opposite surface and so perform the locking play. Thus, the counter-stop surface is formed on the housing cover, which locks correspondingly on the latching hook of the holder base. The housing cover preferably has at least one respective first and one second counterstop surface which, in the closed position, can abut against or abut the corresponding first or second abutment surface.

For ease of assembly, it has proved to be advantageous if the latching hook has a wedge shape and the first stop surface is arranged on a base side of the wedge or parallel thereto. The base side of the wedge can thus also be parallel to the base surface of the holder base. The wedge shape offers the advantage that e.g. the holder cover can slide down to the engagement with the first abutment surface on the side surfaces of the wedge and locked there after exceeding the edge between the side surface and the first abutment surface or base side surface of the wedge.

To accomplish that the latching hook is urged in the closed position in this or held there, the second stop surface may be arranged on a receiving space facing side surface of the wedge. Thus, the second abutment surface is located on an opposite side of the wedge as the first abutment surface. Thus, both can serve each other as an opponent.

Ideally, the latching hook is thus arranged on the holder base and cooperates with a counter-latching element of the holder lid. It is advantageous if at least one first counter-stop surface of the holder cover in the closed position of the holder lid faces the first stop surface or bears against it. When locking the holder cover on the holder base, the first abutment surface and the first counter stop surface form an undercut in the pivoting direction to the open position.

If the latching hook is arranged on the holder lower part, it is locked in the closed position with a counter-latching element of the holder lid. Accordingly, the holder cover has at least one second counterstop surface which, in the closed position of the holder lid, faces or bears against the second stop surface.

For attachment to the motor vehicle, the conductor holder may be attached to a bolt, such as a bolt or, preferably, coarse-threaded bolts. For this purpose, the lower holder part has a first bolt receiving opening, which is formed on a side facing away from the receiving space of the latching hook. The bolt receiving opening is enclosed circumferentially and designed as Duchgangsöffnung. As a result, the holder base can be easily attached to the bolt.

In order to secure the line holder to the bolt without additional attachments, such as a nut, the retaining cover may have a second bolt receiving opening having an engagement collar for engaging a threaded portion of the bolt. First, therefore, the holder base is threaded onto the bolt and then closed the holder cover and thereby also threaded onto the bolt, but the engagement collar is brought into engagement with the bolt. Alternatively, the Conductor holder are pre-assembled to the line so that it is already closed and then attached to the bolt. An additional nut, which can press on the holder cover, but must not be provided due to the self-locking arrangement.

Ideally, in the closed position of the holder cover, the first and second bolt receiving openings are aligned with each other, whereby a particularly compact construction and easy securing of the line holder to the bolt can be achieved.

The invention also relates to a line assembly for mounting in a motor vehicle, with a line holder according to in one or more of the embodiments described above and with at least one optical or electrical line, which is arranged in a receiving space of the line holder.

Particularly advantageously, the line holder can be used when the line is a substantially dimensionally stable or massive flat conductor rail. Even such can be kept stable by the conductor holder.

Detailed description

1 shows in a perspective view a conductor holder 1 which is suitable for mounting one or more electrical and / or optical lines in a motor vehicle. The conductor holder 1 has a holder base 2 and a holder lid 3 on, which has a hinge here as a hinge 4 connected to each other. In a further embodiment, the hinge 4 be replaced by one or more locks. In addition to the hinge 4 can also be provided Sekundärverrastungen. The holder cover 3 can be relative to the holder base 2 between a (in 1 shown) open position and a (in 2 shown) closing position, which is due to the respective pivoting direction V1 or pivoting direction V2 is indicated. From the open position, the closed position in the pivoting direction V2 and, conversely, the closing position from the open position in the pivoting direction V1 reached. The conduit is along or parallel to a conduit extension direction L through the conductor holder 1 guided.

The holder base 2 has a plate-like body 2.1 on, from which are two opposite side walls 2.2 and 2.3 extend vertically away and so between them a recording room 2.4 train for the administration. In the middle of the recording room 2.4 indicates the basic body 2.1 a tongue-shaped spring element 2.5 on, one in the recording room 2.4 directed in spring force can apply. On the first side wall 2.2 are two in the direction of pipe extension L spaced latching hooks 2.6 formed, each having a wedge shape. According to a wedge, the latch hook 2.6 a base side and two side surfaces on which the to the receiving space 2.4 directed side surface of the wedge is approximately flush with the corresponding surface of the side wall 2.2 , whereby the latching hook 2.6 not in the recording room 2.4 protrudes. The other side surface of the wedge is in a receiving space 2.4 opposite direction from the side wall 2.2 starting, which is parallel to the surface of the main body 2.1 extending base of the wedge is exposed in sections. Out 1 also shows that the tip of the wedge of the latching hook 2.6 over the side wall 2.2 protrudes. In addition, the locking hook has 2.6 a first stop surface 2.7 on the exposed base of the wedge and a second stop surface 2.8 at the reception room 2.4 facing side surface. On sidewall 2.2 joins in with the main body 2.1 substantially parallel attachment portion 2.9 with a bolt receiving opening 2.10 at.

On the second side wall 2.3 is the hinged hinge 4 trained and connects so the holder base 2 with the holder lid 3 , The holder cover 3 has a plate-shaped body 3.1 on, which is attached to the hinge 4 side facing away from a side wall 3.2 extends, to which a to the main body substantially parallel, further attachment portion 3.3 followed. In the sidewall 3.2 is a passage opening 3.4 for passing the latching hook 2.6 trained, extending down to the main body 3.1 extends into it. To attach to the motor vehicle has the other attachment section 3.3 over another bolt receiving opening 3.5 in the form of a slot with an engaging collar 3.6 for engaging with a threaded portion or the like. The engaging collar 3.6 is formed by two opposing locking webs which are tapered or hired so that they can slide in the direction of the closed position or at least relatively easily lead over the threaded portion, but lock in the direction of the open position on the threads.

In 2 is the conductor holder 1 now in its closed position. It can be seen that the passage opening 3.4 from a protective wall 3.7 is surrounded, so that passed through snap hook 2.6 protected and unintentional opening of the line holder is avoided. In addition, two (unspecified) tabs make it easier for the installer to attach to the threaded bolt 5 and contribute to the mechanical stability in the area around it.

In 3 is a conduit arrangement 100 with the closed, ie in the closed position, and on a threaded bolt 5 attached conductor holder 1 shown in a sectional view. The conductor holder 1 is with its bolt receiving opening 2.10 of the holder base 2 on the threaded bolt 5 threaded. In the recording room 2.4 are two flat or superimposed flat conductor rails 6 taken with their flat sides together and with their narrow sides on the side walls 2.2 . 2.3 issue. The holder cover 3 spanned with his main body 3.1 the recording room 2.4 and conclude this way. Also the holder cover 3 is with its bolt receiving opening 3.5 on the threaded bolt 5 Threaded, and stands there over the engaging collar 3.6 with the threaded portion of the threaded bolt in engagement. Optionally, it is possible the engagement collar 3.6 over one on the threaded bolt 5 screwed on plastic nut to secure the engagement collar 3.6 holds down. About the holder lid 3 becomes the conductor holder 1 So on the threaded bolt 5 held and thus secures itself to a certain extent. Optionally, it is possible that the holder cover 3 in some cases (especially in the variants of the 1 and 2 ) in addition to or instead of the engagement collar 3.6 is secured by means of a nut, with the threading attachment section 3.3 of the holder cover 3 on the threaded bolt 5 is screwed on and so on the holder cover 3 suppressed.

The retaining cover 3 is on the latching hook 2.6 latched by a first counter stop surface 3.8 an edge of the attachment portion 3.3 with the first stop surface 2.7 of the latching hook 2.6 forms an undercut. This pushes the first counter stop surface 3.8 against the first stop surface 2.7 when the holder cover in the pivoting direction V1 pivoted, so should be opened. At the same time there is also a second counter stop area 3.9 of the holder cover 3 in contact with the second stop surface 2.7 of the latching hook 2.6 , The second counter-attack surface 3.9 is one the recording room 2.4 opposite surface of the mounting portion 3.3 of the holder cover 3 , Illustratively, (pressure) forces acting on the stop surfaces act 2.7 . 2.8 be applied, in different directions on the latching hook 2.6 , So that one stop surface for the other stop surface works as a counter-holder. Because the bolt receiving opening 3.5 is designed as a slot, the first counter stop surface 3.8 at the first stop surface 2.7 be threaded over to release the undercut and the holder cover in the pivoting direction V1 to pivot.
