Description

BACKGROUND OF THE INVENTION

The subject matter herein relates generally to connector assemblies and systems, and more particularly, to a connector assembly having a hinged cover.

Motor vehicles and other equipment include various electronic devices mounted therein. The devices may control various systems and/or subsystems. For example, the motor vehicle may include an audio system or a global positioning system (GPS) therein. It may be desirable for the operator of the vehicle to transmit data between the various electronic devices and an external device, such as a personal computer (PC), a personal digital assistant (PDA), an audio device, such as an MP3 player, a cell phone or other external devices. Other examples of electronic devices on the motor vehicle may include a control computer that controls systems within the motor vehicle such as the fuel system, the transmission, the brakes or the steering mechanism. These control computers are typically coupled to a variety of sensors and/or actuators and the control computers may log data regarding usage of the vehicle, such as maximum speed, fuel usage, maximum acceleration, hours of usage, and the like. It may be desirable to communicate with such control computers for maintenance, diagnostics, and the like.

Accordingly, at least some motor vehicles and equipment include a communication port that provides a communication bridge between the electronic devices mounted in the vehicle and the various external devices. For example, some motor vehicles include a Universal Serial Bus (USB) interface, or other type of interface, to facilitate communication between the devices carried by the motor vehicle and the external devices. The interface allows repeated connection of the various types of external devices. However, over time, and with repeated use, the interface may wear or become damaged, which may degrade or eliminate the signal communicated across the communication bridge. For example, the interface may have a limited number of use cycles. Additionally, the interface may become contaminated by dirt, debris, a liquid spill, and the like. As such, the interface may require repair or replacement over time.

Conventional interfaces in motor vehicles and equipment include a header soldered to a circuit board of the device. When the interface needs replacement, a new circuit board and header is provided to replace the existing one. Such a repair is costly, as the header is typically the component that may need to be replaced.

Accordingly, a need remains for a connector assembly for a motor vehicle that can be manufactured and replaced in a cost effective and reliable manner.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 is an exploded view of a connector system 100 including a connector assembly 110 formed in accordance with an exemplary embodiment. While the illustrated embodiment shows a USB connector, one skilled in the art would know the disclosed features may be used on other connector types. Moreover, while the system 100 described herein is described as being adapted for USB type of connections, it is realized that other types of electrical interconnection systems may be used within the spirit and scope of the subject matter herein, and the system 100 should not be limited to USB headers and USB connectors.

The connector assembly 110 includes a first header 112 that defines a first interface 114. The system 100 also includes a bezel 116 and a cable assembly 118 having a second header 120 defining a second interface 122. In an exemplary embodiment, the first interface 114 defines a user interface and the second interface 122 defines a device interface. The first and second headers 112, 120 define interfaces that may be of the same or different types. For example, the headers may be one of a USB type A, a USB type B, a mini-USB type A, a mini-USB type B, a micro-USB type A, a micro-USB type B, or another USB type. In the illustrated embodiment, the first header 112 defines a USB Standard A receptacle interface, and the second header 120 defines a mini-USB type B receptacle interface.

The connector assembly 110 may be coupled with the bezel 116, which is mounted within a motor vehicle or piece of equipment (not shown). When coupled, the first header 112 is configured to mate with a mating connector (not shown), such as a mating connector of an external device. The external device may be a device such as an MP3 player, a PC, a PDA, a diagnostic device, and the like. The second header 120 of the cable assembly 118 is connected to the connector assembly 110 by a cable 124 and is configured to mate with another mating connector (not shown). For example, the mating connector may be on an electronic device mounted within the vehicle or piece of equipment, such as an audio system, a GPS system, a control computer, and the like.

While the system 100 is shown and described as including the bezel 116, which is mounted within a motor vehicle or piece of equipment, it is realized that the bezel 116 and/or the connector assembly 110 may be mounted within any appropriate type of electronic device. The mounting described herein is intended as illustrative and is not intended to be limited to a motor vehicle or piece of equipment, be it industrial or motive. For example, the bezel 116 may be mounted in any type of electronic device. Additionally, the connector assembly 110 may be mounted without the use of the bezel 116 in some alternative embodiments.

FIG. 2 illustrates the connector assembly 110 with a cover 130 of the connector assembly 110 in an open position. The connector assembly 110 includes a receptacle housing 132 having a plurality of walls defining a component chamber 134. The header 112 is received in the component chamber 134. An opening 136 provides access to the component chamber 134. In an exemplary embodiment, the header 112 is loaded into the component chamber 134 through the opening 136. The cover 130 covers, or closes access to, the opening 136 and/or the component chamber 134. In an exemplary embodiment, the receptacle housing 132 is generally box-shaped having a mating end wall 138, a terminating end wall 140, opposed first and second side walls 142, 144, and a bottom wall 146. The top includes the opening 136. While the receptacle housing 132 is illustrated as being box-shaped, the receptacle housing 132 may have any shape that is configured to receive the header 112.

The header 112 is loaded into the component chamber 134 such that the first interface 114 is provided proximate the mating end wall 138. The cable 124 of the cable assembly 118 (shown in FIG. 1) is connected to the header 112, such as at an end of the header 112 opposite to the mating interface 114. The cable 124 may be terminated to the header 112 in any known manner. The cable 124 extends from the receptacle housing 132 through the terminating end wall 140 proximate to where the cable 124 is terminated to the header 112. A portion of the terminating end wall 140 may define a cable support 148 for supporting the cable 124. In an exemplary embodiment, the receptacle housing 132 includes interior locating walls 150 that locate the header 112 within the component chamber 134. The walls 150 have a predetermined form factor that is sized and shaped to receive the header therein. Optionally, the locating walls 150 may also hold the header 112 and/or the cable 124 in place within the component chamber 134. The walls may securely retain the header 112, such as by a friction fit, or by being sized substantially, but slightly larger than, the header 112 to resist most movement of the header 112 or to allow only slight movement of the header 112. In alternative embodiments, the walls may not securely retain the header 112 within the component chamber 134. Rather, the header 112 may be otherwise retained therein, such as by ribs extending from the walls defining the component chamber 134. In an exemplary embodiment, the header 112 includes tabs 152 at a front end (e.g. at the mating interface end) thereof that are received in corresponding slots 154. The slots 154 hold the tabs 152 and resist movement of the header 112 within the component chamber 134. For example, the slots 154 and tabs 152 and/or the locating walls 150 may resist movement of the header 112 in the direction of the terminating end wall 140, such as when the cable 124 is pulled away from the receptacle housing 132.

The cover 130 is provided for closing access to the component chamber 134. The cover 130 is movable between an open position, such as the position shown in FIG. 2, and a closed position, in which the opening 136 is closed. In the illustrated embodiment, the cover 130 is generally rectangular shaped and includes opposed first and second sides 156, 158. Alternatively, the shape of the cover 130 may be non-rectangular, depending on the shape of the opening 136. In an exemplary embodiment, the first side 156 of the cover 130 is hingedly connected to the first side wall 142 by hinges 160. Optionally, the cover 130, receptacle housing 132 and hinges 160 may be integrally formed, such as by a molding process.

The first side 156 of the cover 130 includes a cover catch 162 extending therefrom. The first side wall 142 includes a locking element 164. When the cover 130 is closed, the cover catch 162 engages the locking element 164 to secure the first side 156 against the receptacle housing 132. In an exemplary embodiment, the cover catch 162 includes a first protrusion 166 in the form of a pin and a second protrusion 168 also in the form of a pin. The locking element 164 includes first and second lids 170, 172 formed in, or extending from, the first side wall 142. The protrusions 166, 168 are captured below the lids 170, 172 when the cover 130 is closed.

The second side 158 of the cover 130 includes one or more securing elements 174 that are configured to engage one or more corresponding securing elements 176 on the second side wall 144 of the receptacle housing 132. The securing elements 174 on the cover 130 may include, and are referred to hereinafter as, latches 174. The securing elements 176 on the receptacle housing 132 may include, and are referred to hereinafter as, latching tabs 176. The latches 174 extend generally perpendicular to the cover 130 and extend along the second side wall 144 when the cover is in the closed position. The latching tabs 176 extend outward from the second side walls 144 and are sized and shaped to fit into apertures in the latches 174. Alternative securing elements 174, 176 may be provided in alternative embodiments to securely retain the second side 158 of the cover against the receptacle housing 132.

FIG. 3 is a bottom perspective view of the connector assembly 110, illustrating the cover 130 in the open position. The receptacle housing 132 includes keying features 180 along the bottom wall 146. The keying features 180 may be positioned along the sides, as illustrated in FIG. 3, or may be positioned elsewhere, such as along a central portion of the bottom wall 146.

The receptacle housing 132 includes an opening 182 through the mating end wall 138 that provides access to the first mating interface 114. In an exemplary embodiment, the first header 112 is a USB type A receptacle that receives a USB plug therein, however other types of interfaces may be provided in alternative embodiments. The opening 182 is sized and shaped to receive the plug of the mating connector (not shown).

FIG. 4 is a top perspective view of the connector assembly 110 with the cover 130 in a closed position. The cover 130 is rotated to the closed position about the hinges 160. The latches 174 are securely engaged with the latching tabs 176 (shown in FIG. 2). The latches 174 keep the second side 158 of the cover 130 closed against the receptacle housing 132. To open the cover 130 again, the latches 174 are released from the latching tabs 176 and the cover 130 is rotated about the hinges 160 to the open position.

The hinges 160 keep the first side 156 of the cover 130 closed against the receptacle housing 132. Although the hinges 160 are intended for multiple uses, it is possible that the hinges 160 may break due to use and/or due to the environment in which the connector assembly 110 is operated. For example, in a motor vehicle, the connector assembly 110 may be subjected to vibrations and other sudden movements that may cause the hinges to break.

The cover catch 162 is employed to additionally secure the first side 156 of the cover 130 closed against the receptacle housing 132. For example, in the closed position, the protrusions 166, 168 (shown in FIG. 2) of the cover catch 162 are captured beneath the lids 170, 172. The lids 170, 172 may resist movement of the cover 130 in a direction generally away from the receptacle housing 132 (e.g. in an opening direction). The cover catch 162 and the locking element 164 supplement the hinges 160 in keeping the cover 130 closed, and thus operate as a secondary securing element. Alternatively, when closed, the cover catch 162 may operate as a primary securing element by substantially eliminating stress on the hinge 160, thus leading to extended hinge life.

FIG. 5 is a side view of the connector assembly 110 being assembled with the bezel 116 of the connector system 100 (shown in FIG. 1). The bezel 116 includes a mating interface 210 for mating with the mating connector (not shown). The bezel 116 may be securely mounted within a structure or frame of, for example, a motor vehicle. A shroud 220 extends away from the mating interface 210. The connector assembly 110 is coupled to the shroud 220, such as by plugging into a rear end 222 of the shroud 220 in a loading direction, shown by arrow A in FIG. 5.

The bezel 116 includes latching features 224 and the connector assembly 110 includes latching features 226. The connector assembly 110 is plugged into the shroud 220 until the latching features 224 of the shroud 220 engage the latching features 226 of the connector assembly 110. In an exemplary embodiment, the latching features 224 of the shroud 220 define deflectable latches 224 and the latching features 226 of the receptacle housing 110 define ramps 226 that extend outward from the side walls 142, 144 (144 is shown in FIG. 2). The deflectable latches 224 include openings 228 therein that are sized and shaped to receive the ramps 226. During mating, the deflectable latches 224 are deflected outward as the connector assembly 110 is loaded into the shroud 220. When mated, the deflectable latches 224 are deflected to securely retain the connector assembly 110 within the shroud 220. For example, the ramps 226 may be received within the openings 228 and a rear end 230 of the ramps 226 may engage the opening 228 to resist removal of the connector assembly 110 from the shroud 220. Alternative latching features known in the art may be used to securely retain the connector assembly 100 within the shroud 220.

FIG. 6 illustrates the connector system 100 in an assembled state. The connector assembly 110 is coupled to the bezel 116 by securing the latching features 224 to the latching features 226. When assembled, the first interface 114 (shown in FIG. 1) is substantially aligned with the mating interface 210 of the bezel 116.

The cable assembly 118 extends from the connector assembly 110. More particularly, the cable 124 extends from the terminating end wall 140. The cable support 148 supports the cable 124. In an exemplary embodiment, the cable support 148 defines a strain relief on the cable 124. The cable support 148 may include a cradle 230 having a cradle wall 232 and projections 234. The cradle 230 may be sized, shaped and/or positioned to receive a strain relief element between the cradle 230 and the terminating end wall 140. For example, a zip tie element (not shown) may be provided that extends around the cradle wall 232 and the cable 124 and that is captured between the projections and the terminating end wall 140. When cinched down, the zip tie element may securely retain the cable 124 within the cradle 230. The zip tie element may provide strain relief for the cable 124.

The second header 120 is provided at the opposed end of the cable 124. A housing 240 may surround the second header 120. The second header 120 is adapted for mating connection with a mating connector. In the illustrated embodiment, the second header 120 represents a USB mini-B plug connector, however other types of interfaces may be provided in alternative embodiments. The cable 124 may have any length.
