20240063592
This application claims the benefit of Italian Patent Application No. 102022000017394, filed Aug. 28, 2022, the whole disclosure of which is incorporated herein by reference.
Embodiments of the present disclosure relate to a panel adapter for mounting an electric connector, such as a panel mount connector of an electric vehicle or other type of electrical system, to a panel. Further, the present disclosure relates to an adapter assembly including such a panel adapter as well as a connection system including such an adapter assembly.
Electric connectors used with cables or wire harnesses are adapted to establish releasable, electrically conductive connections between units that are spaced apart or neighbour each other. For example, an electric motor might need to be connected to an inverter or an inverter requires connection to a battery module, etc. Some of these units are often integrated in a housing or chassis as part of a modular design and/or because they are manufactured by different suppliers. Thus, it is necessary to establish connections through panels, partition walls or housing walls located between the units to be connected. In these cases, electric connectors are mounted at the interface of the units, such as at cutouts of panels.
In order to securely mount the electric connector to the respective panel, a separate securing means which functions similarly to a circlip is loosely provided and must be installed appropriately to the electric connector. In such existing solutions, the securing means, however, has to be positioned, aligned and kept in the correct orientation during the entire installation. This procedure is time consuming and prone to mistakes, since the securing means could slip away or become wedged.
Therefore, it is desirable to have means for mounting electric connectors to panels which are easy to handle while reducing assembly errors.
According to an embodiment of the present disclosure, a panel adapter configured or adapted to mount an electric connector to a panel includes a frame element, a fastening element and a guide structure. The frame element defines at least one frame opening adapted to at least partially receive the electric connector in an insertion direction, and a bearing surface surrounding the frame opening. The fastening element is adapted to fasten the frame element to a cutout of the panel. The guide structure slidably guides a slider element along the bearing surface in a translation direction.
The invention will now be described by way of example with reference to the accompanying Figures, of which:
Exemplary embodiments of the present disclosure will be described hereinafter in detail with reference to the attached drawings, wherein the like reference numerals refer to the like elements. The present disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiment set forth herein; rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the concept of the disclosure to those skilled in the art.
In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawing.
In the following, the structure of possible embodiments of a panel adapter 1 for mounting an electric connector 2, such as a panel mount connector 4 of an electric vehicle (not shown), to a panel 6 is explained with reference to the exemplary embodiments shown in
A bearing surface 20 of the frame element 12 entirely surrounds the frame opening 14. The bearing surface 20 may be formed by a flat side 22 of the frame element 12 and extend perpendicularly to the insertion direction 16. According to another embodiment not shown in the figures, the bearing surface 20 may also be curved, wavy or have an uneven profile formed by the frame element 12 adjusted to the shape of a non-flat panel (not shown). Further, the bearing surface 20 may only surround a circumferential section of the frame opening 14 (e.g., less than 75% of the circumference of the frame opening). That is, the frame opening 14 may be laterally open, instead of being circumferentially closed.
As can be seen in
Still referring to
The panel 6 may be a general panel, a partition wall, a housing wall or part of a chassis to which the electric connector 2 is to be mounted by means of the panel adapter 1 and a slider element 28 (see
At least one guide structure 30 for slidably guiding the slider element is located on the bearing surface 20 of the frame element 12. The guide structure 30 may be monolithically connected with the frame element 12. That is, the guide structure 30 and frame element 12 may be a single-piece component made by injection moulding, additive manufacturing, or the like. Alternatively, the guide structure 30 may be provided as a separate part and fastened to the frame element 12 or directly to the panel 6 by means of screwing, bolting, welding, soldering, gluing, or the like.
The guide structure 30 serves as a guide for the slider element 28, which is movable along the bearing surface 20 in a translation direction 32. In particular, the guide structure 30 extends transversely, preferably perpendicularly to the insertion direction 16 and parallel to the translation direction 32. Specifically, the guide structure 30 may be located adjacent to the frame opening 14 and at least sectionally extend past the frame opening 14.
In the exemplary embodiment shown in
To guide the slider element 28, each guide structure 30 may comprise at least one slide surface 36, preferably multiple slide surfaces 36a, 36b. First slide surfaces 36a may border the bearing surface 20 at an angle, preferably a 90°-angle. Moreover, the first slide surfaces 36a may extend on the two guide structures 30 in a mutually parallel manner. The slider element 28 may be at least partly located between the two guide structures 30, in particular between the first slide surfaces 36a. Further, the first slide surfaces 36a and the bearing surface 20 may jointly define a guiding groove 38 for the slider element 28 (see
The second slide surfaces 36b may be spaced apart from the bearing surface 20. Further, the second slide surfaces 36b may face towards the bearing surface 20. Preferably, the second slide surfaces 36b extend parallel to the bearing surface 20 and define together with the first slide surfaces 36a and the bearing surface 20 a duct 42 for the slider element 28 (see
In
The panel mount connector 4 may comprise at least one recess 50 for at least partially receiving the slider element 28. In particular, the recess 50 may be adapted to engage with the slider element 28, when the slider element 28 is in the securing position 46. The recess 50 may be designed as a groove 52 or slot 54 extending transversely, preferably perpendicularly to the insertion direction 16. More preferably, the slot 54 runs parallel to the guiding groove 38 and duct 42, when the panel mount connector 4 is received in the frame opening 14. Most preferably, the slot 54 forms an extension of the guiding groove 38 and duct 42, when the panel mount connector 4 is received in the frame opening 14.
As can be seen in
The panel mount connector 4 may comprise a flange 58 spaced apart from the slot 54. In particular, the distance between the flange 58 and the slot 54 may be equal to or greater than the height of the frame element 12 measured in the insertion direction 16. In other words, the frame element 12 fits in the space between the flange 58 and the slot 54.
Optionally, the panel mount connector 4 may comprise a seal ring 60 located between the flange 58 and the slot 54. The seal ring 60 may be seated on the flange 58 and be spaced apart from the slot 54. In particular, the distance between the seal ring 60 and the slot 54 may be equal to or smaller than the height of the frame element 12 measured in the insertion direction 16. That is, the frame element 12 only fits in the space between the seal ring 60 and the slot 54, if the seal ring 60 abuts the frame element 12 and, if necessary, is compressed between the flange 58 and the frame element 12.
In the shown embodiments, the slider element 28 comprises two lock sections 56 arranged opposite of each other with respect to the frame opening 14 (see
The adapter assembly 8 may comprise at least one latching element 62 for catching the slider element 28 in the release position 44. Alternatively, the latching element 62 may be adapted for catching the slider element 28 in the securing position 46. Further alternatively, the latching element 62 may be adapted for catching the slider element 28 in an intermediate position 64 between the release position 44 and the securing position 46 (see
As can be seen in the upper left side of
The latching element 62 may be located on the panel adapter 1 or on the slider element 28. Accordingly, the latching element 62 may be adapted to engage with a complementary latching element 68 on the slider element 28 or on the panel adapter 1, respectively. The latching element 68 on the slider element 28 may be additionally or alternatively adapted to engage with a complementary latching element 70 on the panel mount connector 4 (see
The latching element 62 of the panel adapter 1 may be located on the frame element 12 or on the guide structures 30. In particular, the latching element 62 may be a latching cam 72 protruding on the bearing surface 20, wherein the slider element 28 comprises a latching notch (not shown). Optionally, two latching cams 72 may be provided and jointly form a latching notch 74 for the slider element 28. In this case, the slider element 28 itself does not require any latching notch.
Alternatively or additionally, the latching element 62 may be a flexible latching prong 76 formed by the respective guide structure 30. Optionally, each latching prong 76 may form part of the first slide surfaces 36a or the second slide surfaces 36b. Further, each latching prong 76 may comprise a hook (not shown) at a free end for engaging the slider element 28. Optionally, the adapter assembly 8 may comprise two or more latching elements 62 spaced apart from each other for catching the slider element in the release position 44, the securing position 46 and/or the intermediate position 64, respectively.
Further, the frame element 12 may comprise multiple frame openings 14, each for receiving one electric connector 2 (see
