The subject matter herein relates generally to connector assemblies, and more particularly, to connector assemblies mountable to a panel by front loading and rear loading operations.
Some electrical systems and devices today are designed to include ports along the panels or walls of an electrical system or device, such as a portable computer. The ports allow an operator of the system to establish a communication or transmission line to a peripheral device (e.g., an RF antenna, a wireless device, a wireless router, another system). In addition, the ports may allow the operator to establish a power connection for the system or the peripheral device. The system includes a connector assembly that holds contacts configured to mate with a mating connector that is coupled to the peripheral device. The connector assembly is typically mounted to either the front side, or the back side, of the panel using hardware, such as screws, clips, pins, and the like. However, the hardware used for mounting may increase the amount of time and cost to construct the system. Alternatively, when hardware is not used to attach the conventional receptacle to the panel, the receptacle may inadvertently disengage from the panel during normal use of the system.
In some known systems, the connector assembly is mounted to a panel having a cutout. Some known connector assemblies are front loaded into the cutout by loading the connector assembly directly through the cutout from the front of the panel. Other known connector assemblies are rear loaded into the cutout by loading a projection of the connector assembly through a notch in the cutout and then sliding the connector assembly in a direction parallel to the panel. The panel is typically captured between the projection at the front of the panel, and a corresponding projection of the connector assembly at a rear of the panel. Such connectors are referred to as slide-to-lock connectors. The front loaded connector assemblies are not configured to be rear loaded, and the rear loaded connector assemblies are not configured to be front loaded. As such, two different connector assemblies must be designed to accommodate different customers having different mounting requirements.
Thus, there is a need for a connector assembly that may be assembled in more than one way or using more than one type of loading operation. There is a need for a connector assembly that may be easier for a user to mount to a panel than conventional mountable connector assemblies.
In one embodiment, a connector assembly is provided and is adapted for mounting to a panel having a cutout. The connector assembly includes a connector having a body including sides defining a perimeter configured to fit within the cutout. The connector includes a flange extending outward from one of the sides of the body, and the flange is configured to engage a front surface of the panel to define a stop against the panel when the connector is in a mated position. The connector is configured to be one of either front loaded through the cutout from a front of the panel to the mated position or rear loaded through the cutout from a rear of the panel to the mated position.
Optionally, front loading of the connector may be accomplished by loading the connector in a loading direction generally perpendicular to the front surface of the panel, and rear loading may be accomplished by loading the connector in a loading direction non-orthogonal to the front surface. The mated position of the connector with respect to the panel may be the same when the connector is front loaded and when the connector is rear loaded. Optionally, the body may include a mating end, and the flange may extend from the respective side proximate the mating end. The body may include at least two flanges, with each flange having an engagement surface being substantially coplanar with each other engagement surface. The engagement surfaces may engage the front surface of the panel. Optionally, the connector may include at least one spring beam associated with the flange with each spring beam engaging a rear surface of the panel. The connector may include a mating cavity open at a mating end of the body for a cavity length measured along the side having the flange, wherein the flange extends along the respective side for a length that is longer then the cavity length. The flange may extend along at least a majority of the side having the flange.
In another embodiment, a connector assembly adapted for mounting to a panel having a cutout is provided that includes a connector having a body including sides defining a perimeter configured to fit within the cutout. The connector includes a flange extending outward from one of the sides of the body, and the flange has a first end and a second end facing opposite sides of the body. The connector is configured to be loaded through the cutout in a loading direction by initially loading the first end of the flange through the cutout and then moving the connector in the loading direction that is defined at a non-orthogonal angle with respect to a front surface of the panel to a loaded position in which the second end of the flange has clearance from a rear surface of the panel. The connector is moved from the loaded position to a mated position in a mating direction in which the first end is moved toward the front surface.
In a further embodiment, a connector assembly is provided that includes a planar panel having a front surface and a rear surface and having a cutout extending along and within the panel between the front and rear surfaces. The connector assembly also includes a connector having a body including sides defining a perimeter configured to fit within the cutout. The connector includes a first flange extending outward from one of the sides of the body and a second flange extending outward from an opposite one of the sides of the body. The connector is mounted to the panel in a mated position such that the flanges engage the front surface of the panel. The connector is one of either front loaded through the cutout from a front of the panel to the mated position or rear loaded through the cutout from a rear of the panel to the mated position.
The connector assembly 102 may be securely mounted to the panel 108 to provide an interface to the host system 110 for the peripheral device 106. The mating connector 104 of the peripheral device 106 engages and/or mates with the connector assembly 102 to electrically connect the peripheral device 106 and the host system 110, such as to allow communication therebetween. In an exemplary embodiment, the peripheral device 106 may be an RF antenna or other wireless device that is utilized by the host system 110 to operate. However, the connector assembly 102 may be utilized to interface with other types of devices and/or systems. The peripheral device 106 is thus illustrative and is not intended to be limiting or restrictive in any manner.
In an exemplary embodiment, the mating connector 104 defines a plug type connector and the connector assembly 102 defines a receptacle type of connector that receives the mating connector 104. The connector assembly 102 and the mating connector 104 may include complementary mating contacts (not shown) that are configured to engage with one another. In an exemplary embodiment, the connector assembly 102 and the mating connector 104 are multi-port QSL type connectors, such as those developed by Tyco Electronics Corporation. However, the connector assembly 102 and the mating connector 104 may be any type of electrical connectors, including electro-optical connectors.
In an exemplary embodiment, the body 120 includes a dielectric housing portion 126 and a shield portion 128 surrounding the housing portion 126. The shield portion 128 is a conductive shield and is adapted to provide shielding around the housing portion 126, such as from electromagnetic interference. In alternative embodiments, the body 120 may be provided without the shield portion 128 or without the housing portion 126. For example, the body 120 may be of a one-piece construction.
The body 120 includes a mating end 130 at a front of the body 120, and a rear end 132 opposite to the mating end 130. The lines 112 extend from the rear end 132. The body 120 includes a mating cavity 134 and an opening 136 to the mating cavity 134 at the mating end 130. The contacts 122 are held by the body 120 within the mating cavity 134 and the mating cavity 134 is configured to receive the mating connector 104 in operation. In an exemplary embodiment, the body 120 is generally box-shaped and includes four sides that define an outer perimeter of the body 102, namely a top side 138, a bottom side 140, End opposed first and second sides 142, 144. The first and second sides 142, 144 are generally parallel to one another and perpendicular to the top and bottom sides 138, 140. In alternative embodiments, more or less than four sides may be provided and the body may have other shapes other than a box-shape. While the illustrated embodiment is designed for horizontal mounting of the connector assembly to the panel 108, with the top generally upward facing and the bottom generally downward facing, it is realized that alternative mounting orientations are possible, such as vertical mounting or mounting up-side down. As such, the terms top, bottom, upper, lower, upward, downward and the like are relative and based on the orientation of the illustrated embodiment, and are not intended to be restrictive. For example, if the connector assembly 100 were mounted upside down, the top side 138 may be positioned generally vertically below the bottom side 140.
The body 120 extends along a contact axis 146 that extends generally between the mating end 130 and the rear end 132. The mating connector 104 is loaded into the mating cavity 134 along the contact axis 146. The body 120, particularly at the mating end 130, extends along a longitudinal axis 148 that is perpendicular to the contact axis 146 and a lateral axis 150 that is perpendicular to the contact axis 146 and the longitudinal axis 148. In the illustrated embodiment, the body 120 is generally elongated in a horizontal direction such that the top and bottom sides 138, 140 are generally longer than the first and second sides 142, 144. The longitudinal axis 148 is thus parallel to the top and bottom sides 138, 140 and the lateral axis 150 is parallel to the first and second sides 142, 144. The top and bottom sides 138, 140 extend along the longitudinal axis 148 for a length 152 and the first and second sides 142, 144 extend along the lateral axis 150 for a length 154.
In an exemplary embodiment, the body 120 includes a top flange 160 extending outward from the top side 138 of the body 120 and a bottom flange 162 extending outward from the bottom side 140 of the body 120. Optionally, the top and bottom flanges 160, 162 may be positioned adjacent to the mating end 130 of the body 120. Alternatively, the top and bottom flanges 160, 162 may be positioned remote from the mating end 130 such that at least a portion of the body 120 extends forward of the top and bottom flanges 160, 162. The top and bottom flanges 160, 162 each have a height 164 defined from the top side 138 and the bottom side 140, respectively. The top and bottom flanges 160, 162 each have a length 166 extending between opposed first and second ends 168, 169 of the flanges along the longitudinal axis 148. Optionally, the length 166 may be approximately equal to the length 152 of the top and bottom sides 138, 140. Optionally, the length 166 may be longer than a length of the opening 136 to the mating cavity 134. In the illustrated embodiment, the top and bottom flanges 160, 162 are integrally formed with the shield portion 128 of the body 120 and the top and bottom flanges 160, 162 are substantially identical to one another. For example, the shield portion 128, including the top and bottom flanges 160, 162, is stamped and formed from a blank of metal stock material. In alternative embodiments, the top and bottom flanges 160, 162 may be integrally formed with the housing portion 126 or may be separately formed and coupled to the shield portion 128 and/or the housing portion 126. The top and bottom flanges 160, 162 may be sized and/or shaped differently with respect to one another. The top and bottom flanges 160, 162 may be positioned at different locations along the contact axis 146 with respect to one another. Such features may provide keying or polarization when mounting the connector assembly 102 to the panel 108 (shown in
The body 120 includes a plurality of spring beams 170 extending from the top side 138. Similar spring beams also extend from the bottom side 140, but are not shown in
The spring beams 170 are angled outward from the body 120 such that the distal ends 174 are spaced apart from the top side 138. In an exemplary embodiment, the spring beams 170 are integrally formed with the shield portion 128 of the body 120. For example, the shield portion 128, including the spring beams 170, is stamped and formed from a blank of metal stock material. In alternative embodiments, the spring beams 170 may be integrally formed with the housing portion 126 or may be separately formed and coupled to the shield portion 128 and/or the housing portion 126. In other alternative embodiments, the connector assembly 102 may be provided without the spring beams 170, or springs or biasing elements of other types may be utilized to secure the connector assembly 102 to the panel 108.
The body 120 includes a locking finger 180 extending from the top side 138. A similar locking finger also extends from the bottom side 140, but is not shown in
The locking finger 180 is angled outward from the body 120 such that the distal end 184 is spaced apart from the top side 138. In an exemplary embodiment, the locking finger 180 is integrally formed with the shield portion 128 of the body 120. In alternative embodiments, the locking finger 180 may be integrally formed with the housing portion 126 or may be separately formed and coupled to the shield portion 128 and/or the housing portion 126. In other alternative embodiments, the connector assembly 102 may be provided without the locking finger 180, or locking or latching elements of other types may be utilized to position the connector assembly 102 with respect to the panel 108.
Terms such as forward facing or positioned forward of or in front of generally refer to a direction toward the exterior of the system 100, and terms such as rearward facing or positioned rearward of or behind generally refer to a direction toward the interior of the system 100.
The cutout 200 illustrated in
The cutout 200 defines a window through which the connector assembly 102 is loaded. As described in further detail below, the connector assembly 102 may be front loaded (e.g. loaded from the front) or rear loaded (e.g. loaded from the rear) through the cutout 200 in the panel 108. The cutout 200 has a similar shape as the outer perimeter of the connector assembly 102. For example, the cutout 200 may have an upper edge 208, a lower edge 210 and first and second side edges 212 and 214 that generally face the top, bottom, first and second sides 138-144 (shown in
In an exemplary embodiment, the cutout 200 includes a plurality of flange notches 216 and finger notches 218, which may be an optional feature depending on the inclusion and orientation of the locking finger 180 (shown in
During assembly, the connector assembly 102 is initially loaded into the cutout 200 by positioning the first side 142 of the body 120 at the mating end 130 into the cutout 200. In particular, the top and bottom flanges 160, 162 are loaded into the flange notches 216. Generally, for rear loading, the connector assembly 102 only fits into the cutout 200 by aligning the flanges 160, 162 with the flange notches 216. The overall height of the body 120 at the flanges 160, 162 is taller than the height of the main portion of the cutout 200, but the height of the cutout 200 at the flange notches 216 is tall enough to accommodate the body 120 and the flanges 160, 162.
When the connector assembly 102 is initially loaded into the cutout 200, the connector assembly is angled with respect to the panel 108. For example, the mating end 130 of the body 120 is oriented at a loading angle 250, such as an acute angle, with respect to the panel 108. The angle 250 may be defined by a width 252 of the flange notch 216. For example, when loaded, a rear surface of each flange 160, 162 engages the front surface 202 of the panel 108 proximate the transition edge 222 and a front surface of each flange 160, 162 engages the rear surface 204 of the panel 108 proximate the second side edge 214. By increasing the width 252 of the flange notches 216, the angle 250 may be reduced as the mating end 130 may be positioned generally closer to parallel to the panel 108.
In some embodiments, the loading angle 250 may be a range of angles. For example, the minimum angle may be defined by the situation in which the rear and front surfaces of the flanges 160, 162 engage the front and rear surfaces 202, 204 of the panel 108. However, the connector assembly 102 may be loaded through the cutout 200 at other angles that are greater than the minimum loading angle, such as by moving the second side 144 generally away from the rear surface 204 of the panel 108, such as closer to an angle in which the mating end 130 is perpendicular to the panel 108. In an exemplary embodiment, the loading angle 250 may be between approximately 30 and 60 degrees. Optionally, the loading angle 250 may be approximately 45 degrees. In some embodiments, the loading angle 250 may be between approximately 0 and 90 degrees.
After the connector assembly 102 is initially loaded into the cutout 200, loading of the connector assembly 102 is accomplished by moving the connector assembly 102 in a loading direction, represented by the arrow 254. For example, pushing on the second side 144 of the body 120 forces the connector assembly 102 to move in the loading direction 254. The loading direction 254 is generally oriented along the loading angle 250. The loading direction 254 is generally a linear direction. Optionally, the loading direction 254 may change during loading, such as when the loading angle 250 is changed.
The spring fingers 170 and the locking finger 180 are illustrated in
In the loaded position, the first side 142 of the body 120 engages the first side edge 212 of the cutout 200. The portion of the first side 142 that engages the first side edge 212 is located remote with respect to the mating end 130 of the body 120, such as at a location proximate a center of the first side 142. In the loaded position, the mating end 130 of the body 120 at the second side 144 is substantially aligned with the second side edge 216 of the cutout 200. In an exemplary embodiment, the corner of the body 120 defined at the mating end 130 and the second side 144 may be cleared beyond the rear surface 204 and/or the front surface 202 of the panel 108.
In the loaded position, the corner of the body 120 defined at the mating end 130 and the first side 142 is positioned a distance 260 from the front surface 202 of the panel 108. The distance 260 may be controlled by the loading angle 250 (shown in
Once the connector assembly 102 is in the loaded position, the connector assembly 102 may be transitioned to a mated position (shown in
During assembly, when the connector assembly 102 is transitioned from the loaded position (shown in
During loading, the cable end 132 of the body 120 is initially loaded through the cutout 200 in the panel 108. The connector assembly 120 is loaded until the flanges 160, 162 at the mating end 130, which is opposite to the cable end 132, engage the front surface 202 of panel 108. The lines 112 may be preloaded through the cutout 200. Alternatively, the lines 112 may be connected to the connector assembly 102 after the connector assembly 102 is mounted to the panel 108.
