Definitions

  • the present disclosure relates generally to electronic assemblies. More particularly, the present disclosure is directed to sealed and unsealed electronic assemblies using a common design.
  • Electronic assemblies used on vehicles may be installed or packaged in various locations of the vehicle. Some locations, such as the exterior of the vehicle, may require that the electronic assemblies are sealed to prevent intrusion of moisture and or contaminants. In contrast, the electronic assemblies packaged in interior locations do not require a sealed arrangement. In fact, for interior locations, it may even be preferable that the electronic assembly is not sealed in order to provide better ventilation and/or cooling. Furthermore, different wiring connectors (e.g., sealed vs. unsealed) may be needed depending on the packaging location. As a result, the prior art electronic assemblies are designed for their intended use — one design for use in an exterior environment and a separate design for use in an interior environment. However, the requirement to manufacture and store multiple assembly designs results in increased cost and complexity. Accordingly, there remains a continuing need for an electronic assembly with more universal parts and which can be used in both exterior and interior applications.
  • an electronic assembly including a housing and an electrical connector that is one of an unsealed connector and a sealed connector.
  • the electronic assembly also includes a printed circuit board disposed at least partially in the housing.
  • the printed circuit board is configured to accept either one of the unsealed connector and the sealed connector. Consequently, the electronic assembly can be used in both exterior and interior applications.
  • an electronic assembly including a housing having a top portion.
  • the housing also includes a bottom portion configured to attach to the top portion and define a compartment therebetween.
  • a printed circuit board is disposed at least partially in the housing.
  • An electrical connector is attached to the printed circuit board and is one of an unsealed connector and a sealed connector.
  • At least one of the top portion and the bottom portion is configured to receive either the unsealed connector in an unsealed fashion or the sealed connector in a sealed fashion.
  • FIG. 1 is an exploded view of an electronic assembly including a unsealed connector according to aspects of the disclosure.
  • FIG. 2 is an exploded view of the electronic assembly including a sealed connector and additional components for sealing the electronic assembly according to aspects of the disclosure.
  • an electronic assembly 20, 20’ is provided.
  • the electronic assembly 20, 20’ includes a housing 22.
  • the electronic assembly 20, 20’ also includes an electrical connector 24, 24’ that is one of an unsealed connector 24 (FIG. 1) or a sealed connector 24’ (FIG. 2).
  • the electronic assembly 20, 20’ includes a printed circuit board 26 disposed at least partially in the housing 22. The printed circuit board 26 is configured to accept the one of the unsealed connector 24 and the sealed connector 24’.
  • the housing 22 includes a top portion 28 and a bottom portion 30 configured to attach to the top portion 28 over the printed circuit board 26.
  • the top portion 28 and the bottom portion 30 define a compartment 32 therebetween.
  • at least one of the top portion 28 and the bottom portion 30 is configured to receive (i.e., house and secure) the one of the unsealed connector 24 in an unsealed fashion and the sealed connector 24’ in a sealed fashion. So, the same housing 22 may be used regardless of which electrical connector 24, 24’ is used, as either is accommodated.
  • the compartment 32 is divided into a board portion 34 and a connector portion 36 by a partition 38 formed in the top portion 28 of the housing 22.
  • the top portion 28 includes or acts as a heatsink 40 configured to be adjacent the printed circuit board 26 (e.g., in the board portion 34 of the compartment 32) and remove heat from the printed circuit board 26.
  • a plurality of board fasteners 41 secure the printed circuit board 26 to the top portion 28 of the housing 22.
  • a plurality of housing fasteners 42 (e.g., screws) attach the top portion 28 to the bottom portion 30. Nevertheless, it should be understood that such fasteners 41, 42 may be omitted if, for example, the top portion 28 and the bottom portion 30 are configured to snap together while securing the printed circuit board 26.
  • the unsealed connector 24 includes a plurality of unsealed terminals 44
  • the sealed connector 24’ includes a plurality of sealed terminals 46 (FIG. 2).
  • the printed circuit board 26 includes electrical traces 48 (e.g., electrically conductive or copper or metal traces) disposed thereon for conducting electrical signals and/or power (e.g., electrical power for powering the electronic assembly 20, 20’) to and from the electrical connector 24, 24’.
  • the electrical traces 48 are configured to connect to one of the plurality of unsealed terminals 44 and the plurality of sealed terminals 46 depending on whether the electrical connector 24, 24’ is the unsealed connector 24 or the sealed connector 24’.
  • the tracing 48 of the printed circuit board 26 is laid out to accept either (i.e., both, one at a time) the sealed connector 24’ or the unsealed connector 24.
  • the housing 22 also defines a breather opening 50 (e.g., in the bottom portion 30) for equalizing pressure within the housing 22.
  • the electronic assembly 20, 20’ further includes a breather valve 52 disposed in the breather opening 50 for equalizing the pressure within the housing 22, while preventing the intrusion of moisture or contaminants.
  • the top portion 28 of the housing 22 defines a gasket notch 54 around at least a portion of a periphery 56 of the top portion 28.
  • the top portion 28 of the housing 22 also defines a cover plate recess 58 extending into the top portion 28 (e.g., open to the connector portion 36 of the compartment 32).
  • the electronic assembly 20, 20’ includes a gasket 60 (e.g., a form-in-place (FIP) gasket) disposed in the gasket notch 54 for sealing the top portion 28 of the housing 22 to the bottom portion 30 of the housing 22.
  • FIP form-in-place
  • the electronic assembly 20, 20’ also includes a connector cover plate 62 disposed in the cover plate recess 58 and defining a connector recess 64 extending into the connector cover plate 62.
  • the connector recess 64 is configured to receive the sealed connector 24’.
  • the sealed connector 24’ includes a connector channel 66 extending around the sealed connector 24’, the connector channel 66 engages a plate rim 68 of the connector cover plate 62 when the sealed connector 24’ is disposed in the connector recess 64 of the connector cover plate 62.
  • the electronic assembly 20, 20’ additionally includes a plurality of connector cover plate fasteners 70 for attaching the connector cover plate 62 to the top portion 28 of the housing 22.
  • the electronic assembly 20, 20’ may be used across vehicle lines, for example. More specifically, when no sealing is required, electronic assembly 20 may be used; however, if sealing is required, electronic assembly 20’ may be used. Because the traces 48 of the printed circuit board 26 are laid out to accept either the sealed connector 24’ or the unsealed connector 24, the printed circuit board 26, top portion 28 and bottom portion 30 of the housing 22, board fasteners 41, housing fasteners 42, can advantageously be common between the electronic assemblies 20, 20’.
  • cover plate recess 58 extending into the top portion 28 is large enough for either the sealed connector 24’ or the unsealed connector 24 and, thus, when sealing is required, the connector cover plate 62 may be utilized in addition to the sealed connector 24’ and breather valve 52 (i.e., these parts are added to the common or universal design of the electronic assembly 20 to result in electronic assembly 20’).
  • first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.
