Description

BACKGROUND OF THE INVENTION

The subject matter herein relates generally to latching arrangements for electrical connectors.

Electrical connectors are provided for use in many different applications. Typically, the electrical connectors include side latches on both sides to hold both sides of the electrical connectors together. However, due to assembly error, one of the side latches may not be fully latched causing the electrical connector to rotate and possibly have electrical disconnects. When using small electrical connectors or when working in a small space, it may be difficult for an installer to visibly see that both side latches are fully engaged. Additionally, some applications are blind-mate where the installer is unable to see the electrical connectors. In such applications it may be difficult or impossible to use tools to assemble or disassemble the electrical connectors.

A need remains for a connector system that allows reliable and cost effective latching for electrical connectors.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 illustrates a connector system 100 for an electronic device formed in accordance with an exemplary embodiment. The electronic device may be any type of electronic device. For example, the electronic device may be a display screen, such as a television display screen. In various embodiments, the electronic device may be provided in a head rest in an airline passenger seat. The electronic device may be used in other applications in alternative embodiments. Other types of electronic devices may utilize the connector system 100 in other various embodiments.

The electronic device includes a circuit board 104. The connector system 100 is electrically connector to the circuit board 104. The connector system 100 may provide data and/or power to the circuit board 104 for operating other components of the electronic device. The connector system 100 includes a first electrical connector 110 and a second electrical connector 112 mated to the first electrical connector 110. The first electrical connector 110 is mounted to the circuit board 104. The second electrical connector 112 is provided at an end of a cable bundle having one or more cables 114 that provide data and/or power to the electrical connector 112. The electrical connector 110 may be referred to hereinafter as a circuit board connector 110. The electrical connector 112 may be referred to hereinafter as a cable connector 112. When referring to the first electrical connector 110, the second electrical connector 112 may define and be referred to hereinafter as a mating connector 112. When referring to the second electrical connector 112, the first electrical connector 110 may define and be referred to herein after as a mating connector 110.

In an exemplary embodiment, the electronic device 110 may be small or may have a limited amount of working space for mating the electrical connectors 110, 112. For example, when used as a head rest monitor in a head rest of a passenger seat of an airplane, the electronic device may have a low profile and may have a limited amount of working space behind the electronic device for mating the cable connector 112 to the circuit board connector 110. In an exemplary embodiment, the electrical connectors 110, 112 have a low profile to reduce or fit in a small envelope defined by the electronic device. In an exemplary embodiment, the electrical connector 112 may be mated to the electrical connector 110 using tool-less coupling features. As such, the installer does not need to access either electrical connector 110, 112 with tools to make the electrical connection therebetween.

In an exemplary embodiment, the electrical connectors 110, 112 have blind mating features that allow the installer to mate the electrical connectors 110, 112 without visibly seeing or aligning the electrical connectors 110, 112. Optionally, the cable connector 110 may have the cables 114 extending from one of the sides thereof. The cable connector 112 thus defines a right angle connector where the cables 114 extend perpendicular from the mating face of the cable connector 112. In an exemplary embodiment, the electrical connectors 110, 112 provide electrical shielding, such as from electromagnetic interference (EMI). The cable connector 112 may provide cable strain relief for the cables 114. In an exemplary embodiment, the cable connector 112 may be oriented relative to the circuit board connector 110 such that the cables 114 are able to extend from either the left side or the right side relative to the circuit board connector 110. For example, the cable connector 112 may be oriented in a first orientation wherein the cables 114 extend from the left side thereof or may be oriented in a second orientation where the cables 114 extend from the right side thereof. The cable connector 112 may be assembled in multiple configurations to allow the left cable exit or the right cable exit depending on the particular electronic device.

FIG. 1 shows the connector system 100 with the second electrical connector 112 poised for mating with the first electrical connector 110 in a first orientation. FIG. 2 shows the connector system 100 showing the second electrical connector 112 poised for mating with the first electrical connector 110 in a second orientation. In the first orientation (FIG. 1), the cable connector 112 is orientated such that the cables 114 exit from the left side of the cable connector 112. In the second orientation (FIG. 2), the cable connector 112 is oriented such that the cables 114 exit from the right side of the cable connector 112. The circuit board connector 110 has the same orientation in either embodiment.

In an exemplary embodiment, the spring beams 186 are integrally formed with the conductive shield 124. For example, the spring beams 186 may be stamped and formed from the top 172.

FIG. 6 is a front perspective view of the cable connector 112 formed in accordance with an exemplary embodiment. FIG. 7 is an exploded view of the cable connector 112. FIG. 8 is a partially assembled view of a portion of the cable connector 112.

The cable connector 112 includes a contact holder 220 configured to hold a plurality of contacts 222. The contacts 222 are configured to be mated with corresponding contacts 122 of the circuit board connector 110. The cable connector 112 includes a housing 224 configured to hold the contact holder 220 and the contacts 222. In an exemplary embodiment, the housing 224 is conductive and provides electrical shielding for the contacts 222. The cable connector 112 includes a primary latch 226 held by the housing 224. The primary latch 226 is used for securing the cable connector 112 to the circuit board connector 110. For example, the primary latch 226 may latchably engage the primary latch 180 (shown in FIG. 4) of the circuit board connector 110.

The contacts 222 extend between mating ends 230 and terminating ends 232 opposite the mating ends 230. In an exemplary embodiment, the contacts 222 are crimp contacts configured to be crimped to ends of wires 234 of the cables 114. The contacts 222 may be terminated to the wires 234 by other processes in alternative embodiments. The contacts 222 may include pins or sockets at the mating ends 230 for mating with corresponding contacts 122. In an exemplary embodiment, the cable connector 112 includes both signal contacts and power contacts.

The contact holder 220 may include a front contact holder 240 and a rear contact holder 242, which may be coupled to the front contact holder 240. For example, the rear contact holder 242 may be coupled to the front contact holder 240 using adhesive, fasteners or by other processes. The front contact holder 240 holds the contacts 222. The rear contact holder 242 may hold the contacts 222 and/or the wires 234. In an exemplary embodiment, the front contact holder 240 includes a plurality of contact channels 244 that receive corresponding contacts 222.

The contacts 222 may be removed from the contact channels 244 by releasing the latches.

In an exemplary embodiment, the contact holder 222 may include polarizing features 246 for polarized mating with the mating connector 110. For example, in the illustrated embodiment, the front contact holder 240 includes angled sides 248, 250 such that the front contact holder 240 has a generally trapezoidal shape. The front contact holder 240 may have other shapes in alternative embodiments. The polarizing features 246 insure that the cable connector 112 is mated in a particular orientation relative to the mating connector 110. Optionally, the front contact holder 240 may be held in the housing 224 in different orientations (e.g. right side up vs. upside down) to change the orientation of the polarizing features, and thus change the mating orientation of the cable connector 112 with respect to the circuit board connector 110. As such, the cable exit orientation may change.

The primary latch 226 includes a base 260, an actuator 262 forward of the base 260 and a latching beam 264 forward of the actuator 262. Optionally, the base 260 may be fixed in the housing 224 with the actuator 262 exposed exterior of the housing 224 for actuation and releasing of the primary latch 226. When the actuator 262 is pressed, the latching beam 264 may be moved from a latched position to an unlatched position. The latching beam 264 has a hook 266 at the distal end of the latching beam 264. In the illustrated embodiment, the hook 266 is turned outward. The hook 266 is configured to latchably engage the primary latch 180 (shown in FIG. 4) of the circuit board connector 110 to latchably secure the cable connector 112 to the circuit board connector 110.

The housing 224 includes a chamber 270 that receives the contact holder 220 and the contacts 222. In an exemplary embodiment, the housing 224 is a two part housing including a first shell 272 and a second shell 274. The first and second shells 272, 274 form the chamber 270. The first and second shells 272, 274 may form a clam shell arrangement. The first shell 272 may be secured to the second shell 274 using fasteners (not shown). Optionally, the first shell 272 may be hingeably coupled to the second shell 274.

The housing 224 includes a front 280, a rear 282 and opposite sides 284, 286 extending between the front 280 and the rear 282. In an exemplary embodiment, the first shell 272 defines a first end 288 of the housing 224 and the second shell 274 defines a second end 290 of the housing 224. Optionally, the first end 288 may define a top of the housing 224 while the second end 290 defines a bottom of the housing 224. In other embodiments, the housing 224 may be oriented such that the second end 290 defines a top of the housing 224 while the first end 288 defines a bottom of the housing 224. For example, by changing an orientation of the contact holder 222 in the chamber 270, one or the other end 288, 290 may define the top while the other end 288, 290 defines the bottom.

In an exemplary embodiment, the housing 224 includes a latch pocket 292 along the first side 284. The latch pocket 292 is configured to receive the primary latch 226. The base 260 may be fixed in the latch pocket 292, while the actuator 262 and latching beam 264 may move within the latch pocket 292. In an exemplary embodiment, the housing 224 includes a plurality of cable exits 294 at the second side 286. The cables 114 may pass through corresponding cable exits 294. The cables 114 extend into the chamber 270 through the cable exits 294. Optionally, if fewer cables 114 are utilized than cable exits 294 provided, plugs may be received in the cable exits 294 to reduce EMI leakage through the unused cable exits 294.

The housing 224 includes one or more guide pins 296 extending from the front 280. Optionally, the guide pins 296 may be integral with the housing 224. In the illustrated embodiment, two guide pins 296 are provided flanking either side of the chamber 270. In an alternative embodiment, a single guide pin 296 is provided at or near the second side 286 opposite the primary latch 226. Such guide pins 296 holds the second side 286 while the primary latch 226 holds the first side 284. The guide pins 296 are used to guide mating of the cable connector 112 with the circuit board connector 110. The guide pins 296 are configured to be received in corresponding guide pin pockets 160 (shown in FIG. 2). In the illustrated embodiment, the guide pins 296 are cylindrical; however, the guide pins 296 may have other shapes in alternative embodiments. Optionally, distal ends of the guide pins 296 may be tapered to provide lead-in when mating the guide pins 296 to the mating connector 110.

In an exemplary embodiment, the guide pins 296 include grooves 298 in the exterior surfaces thereof. The grooves 298 may extend circumferentially around the guide pins 296 or may be formed only along the top of the guide pins 296. The grooves 298 define secondary latches 300 of the cable connector 112. The secondary latches 300 are configured to engage corresponding secondary latches 182 (shown in FIG. 2) of the circuit board connector 110 to provide secondary securing for the cable connector 112 to the mating connector 110. For example, the primary latch 226 may be used to secure the first side 284 to the mating connector 110 while the secondary latch 300 may be used to secure the second side 286 to the mating connector 110.

The housing 224 includes a latch shield 302 near the latch pocket 292. The latch shield 302 extends forward from the front 280. The latch shield 302 is provided outside of the primary latch 226 and provides shielding for the primary latch 226 to prevent damage to the primary latch 226. The latch shield 302 may be used to align the cable connector 112 with the circuit board connector 110.

In an exemplary embodiment, the cable connector 112 includes a contact shell 310 provided at the front of the cable connector 112. The contact shell 310 may form a part of the housing 224. In an exemplary embodiment, the contact shell 310 is conductive and provides electrical shielding for the mating ends 230 of the contacts 222. The front contact holder 240 may be received in the contact shell 310. The contact shell 310 may have a complementary shape as the front contact holder 240. For example, the contact shell 310 may have angled sides that define polarizing features of the cable connector 112 for polarized mating with the circuit board connector 110.

Optionally, the contact shell 310 may be a separate piece from the first and second shells 272, 274 to allow the contact shell 310 to have different orientations with respect to the shells 272, 274 when coupled thereto. For example, the contact shell 310, the contact holder 220 and the contacts 222 may form a contact sub-assembly that may be assembled and loaded into the housing 224. For example, the contacts 222 may be loaded into the contact holder 220 and the contact shell 310 may be coupled to the front contact holder 240 to form the contact sub-assembly 312. The contact sub-assembly 312 may then be loaded into the second shell 274 with the cables 114 extending through the cable exits 294. The contact sub-assembly 312 may be loaded into the second shell 274 in a right-side up orientation or an upside-down orientation to change the orientation of the polarizing features relative to the housing 224. In other words, the wider end of the contact shell 310 and front contact holder 240 may be upward facing when loaded into the second shell 274 or may be downward facing when loaded into the second shell 274. As such, when the cable connector 112 is mated to the circuit board connector 110, the cable connector 112 may have the cables exiting to the right or to the left relative to the circuit board connector 110 depending on the orientation of the cable connector 112 with respect to the circuit board connector 110.

Returning to FIGS. 1 and 2, during mating the cable connector 112 is aligned with the circuit board connector 110 in either a left cable exit orientation (FIG. 1) or a right cable exit orientation (FIG. 2). In the left cable exit orientation, the primary latch 226 is on the right side of the cable connector 112 and aligned with the corresponding latch pocket 162 of the circuit board connector 110. In the right cable exit orientation, the primary latch 226 is on the left side of the cable connector 112 and aligned with the corresponding latch pocket 162 of the circuit board connector 110. The primary latch 226 is configured to engage the primary latch 180 of the circuit board connector 110 when mated thereto. In an exemplary embodiment, the primary latch 226 may make an audible click sound when properly latched to the primary latch 180.

The guide pins 296 are aligned with the guide pin pockets 160 during mating. In an exemplary embodiment, the guide pins 296 extend further forward than the contact shell 310, the primary latch 226 or the latch shield 302. The guide pins 296 are the first portions of the cable connector 112 to mate with the circuit board connector 110. The guide pins 296 may be used for blind mating of the cable connector 112 by aligning the cable connector 112 with the circuit board connector 110 for mating the contacts 222, 122.

When mated, the grooves 298 of the guide pins 296 are received in the guide pin pockets 160 and aligned with the secondary latches 182. The secondary latches 182 are received in the grooves 298 to provide a securing or holding force of the guide pins 296 in the circuit board connector 110. The secondary latches 182 are spring biased into the grooves 298 to provide the holding force. As such, a latching arrangement is provided for the electrical connectors 110, 112 whereby the primary latch 226 provides the primary retaining or securing force for the first side 284 of the cable connector 110, the secondary latches 182 provide retaining or securing force for the second side 286 of the cable connector 110. Only one actuatable latch is used for latching, while secondary latching is provided with the secondary latches that are engaged and disengaged by pushing or pulling the cable connector 112 in a mating or unmating direction. The secondary latches provide a simpler latching arrangement then providing two actuatable latches. Additionally, the latching arrangement may be accomplished without the need for additional tools.
