20230402802
The present embodiments relate to electronic connectors and, more particularly, to multi-head cable connectors for providing connections via a cable having plural inputs.
In many applications, it is desirable to provide inputs of differing formats or outputs of differing formats. For example, in many videoconferencing and other video applications, it is often desirable to be able to receive signals of USB, USB-C, micro-USB, HDMI, DisplayPort, Mini DisplayPort and/or other signal formats and then output the signal in another of these formats. Ordinarily, to convert an input signal of one format to an output signal of another format, a dongle is used that has a connector at one end for the input of that format and a connector at the other end for the output of another format. Because such dongles only convert from one particular format to another, to be able to convert from one of multiple possible input formats to an another of multiple possible output formats requires having a particular dongle for each possible pairing of input and output formats. Thus, an individual preparing to attend a video conference or meeting, for example, would be required either to know in advance the formats to be used for video input and output, or alternatively, carry a number of dongles with them for the meeting.
To avoid the necessity of carrying a large number of different dongles, 2-in-1 or 3-in-1 cables are known in which two or more cables of differing input formats join together and output to a single cable of a further format. However, because only one of the two or three input cables is used, the unused unput cables are left to dangle and possibly get in the way of the user's or others' devices.
Alternatively, multi-head cables are known in which several input terminals of different formats extend from a single rigid end piece from which a single output cable extends. For example, the Crestron® Mercury™ Multihead HD Video Cable provides HDMI, DisplayPort, Mini DisplayPort and USB inputs from a single connector head and outputs an HDMI format signal. Alternatively, the Cisco Multi-Head cable provides a single connector head with USB, Mini DisplayPort, and HDMI inputs to a single HDMI output. Each of these multi-head connectors have a single connector block that, when one of its terminals is connected into a port of a laptop or other device, could block, or interfere with the ability to connect to other adjacent ports of the device.
It is therefore desirable to provide a multi-head cable connector that is capable of receiving inputs of different formats and that can connect to one port of a laptop or other device without obstructing the other ports of the device.
It is to be understood that both the general and detailed descriptions that follow are exemplary and explanatory only and are not restrictive.

The front flexible element 122 includes a curved front surface 206 in which a plurality of ribs 204 are formed, as well as a flat rear surface 208. The curvature of the front surface 206 results in the front flexible element 122 having a more rigid, thicker upper portion 212, a thinner middle portion 214, and a more rigid, thicker lower portion 216. The thinner middle portion 214 provides a bendable region for the front flexible element 122, particularly at its narrowest point.
An extension 202 is located at the bottom of the front flexible element 122 and is used for securing the front flexible element 122 in place. Specifically, the flat rear surface 208 of the front flexible element 122 is placed against the front surface of the flexible part 105, and then the extension 202 is held in place by the front cover plate 140.
The front flexible element 124 includes a curved front surface 306, in which a plurality of ribs 304 are formed, as well as a flat rear surface 308. The curvature of the front surface 306 results in the front flexible element 124 having a more rigid, thicker upper portion 312 and lower portion 316, with a thinner middle portion 314 between the upper portion 312 and the lower portion 316. The thinner middle portion 314 provides a bendable region for the front flexible element 124, particularly at its narrowest point.
An extension 302 is located at the bottom of the front flexible element 124 and is used for securing the front flexible element 124 in place. Specifically, the flat rear surface 308 of the front flexible element 124 is placed facing the front surface of the flexible part 107, and then the extension 302 is held in place by the front cover plate 140.
The front flexible element 126 includes a curved front surface 406, in which a plurality of ribs 404 are formed, as well as a flat rear surface 408. The curvature of the front surface 406 results in the front flexible element 126 having a more rigid, thicker upper portion 412 and lower portion 416, with a thinner middle portion 414 between the upper portion 412 and the lower portion 416. The thinner middle portion 414 provides a bendable region for the front flexible element 126, particularly at its narrowest point.
An extension 402 is located at the bottom of the front flexible element 126 and is used for securing the front flexible element 126 in place. Specifically, the flat rear surface 408 of the front flexible element 126 is placed facing the front surface of the flexible part 109, and then the extension 402 is held in place by the front cover plate 140.
The back flexible element 132 also includes a thicker upper portion 512, a thinner middle portion 514, and a thicker lower portion 516 which are analogous to the upper portion 212, the middle portion 214, and the lower portion 216, respectively, of the front flexible element 122. The thinner middle portion 514 of back flexible element 132 also provides the back flexible element 132 with a bendable region analogous to that of the middle portion 214 of the front flexible element 122.
An extension 502 is located at the bottom of the back flexible element 132 and is used for securing the back flexible element 132 in place using the back cover plate 142 in a manner analogous to that of the extension 202.
The back flexible element 134 also includes a thicker upper portion 612, a thinner middle portion 614 and a thicker lower portion 616 which are analogous to the upper portion 312, the middle portion 314, and the lower portion 316, respectively, of the front flexible element 124. The middle portion 614 of the back flexible element 134 therefore provides the back flexible element 134 with a bendable region analogous to that of the middle portion 314 of the front flexible element 124.
An extension 602 is located at the bottom of the back flexible element 134 and is used for securing the back flexible element 134 in place using the back cover plate 142 in a manner analogous to that of the extension 302.
The back flexible element 136 also includes a thicker upper portion (not shown), a thinner middle portion (not shown) and a thicker lower portion (not shown), which are analogous to the upper portion 412, the middle portion 414, and the lower portion 416, respectively, of the front flexible element 126. The middle portion of the back flexible element 136 thus provides the back flexible element 136 with a bendable region analogous to that of the middle portion 414 of the front flexible element 126.
An extension (not shown) is located at the bottom of the back flexible element 136 and is used for securing the back flexible element 136 in place using the back cover plate 142 in a manner analogous to that of the extension 402.

Similarly, when the rear surface 308 of the front flexible element 124 is mounted atop the front surface of the flexible part 107 of the second finger or branch 106, and the rear surface 608 of the back flexible element 134 is mounted atop the rear surface of the flexible part 107, the combination of the bendable, thin metal flexible part 107, the bendable, thinner region 314 of the front flexible element 124, and the bendable, thinner region 614 of the back flexible element 134 permit the second finger or branch 106 to be sufficiently flexible so as to be bendable while also being sufficiently rigid so as the return the second finger or branch 106 to its original position after bending.
Also, when the rear surface 408 of the front flexible element 126 is mounted atop the front surface of the flexible part 109 of the third finger or branch 108, and the rear surface 708 of the back flexible element 136 is mounted atop the rear surface of the flexible part 109, the combination of the bendable, thin metal flexible part 109, the bendable, thinner region 414 of the front flexible element 126, and the bendable, thinner region of the back flexible element 136 permit the third finger or branch 108 to be sufficiently flexible so as to be bendable while also being sufficiently rigid so as the return the third finger or branch 108 to its original position after bending.
In accordance with the embodiment, the first finger or branch 104 is flexible and may be bent up or down to be clear of the port 1104 and allow another cable connector to be inserted into the port 1104. Upon removal of the connector terminal of the second finger or branch 106 from the port 1102, the first finger or branch 104 reverts to its original shape.
Similarly, the third finger or branch 108 is flexible and may be bent up or down to be clear of the ports 1106 and 1108 to allow additional connectors to be inserted into these ports. Upon removal of the connector terminal of the second finger or branch 106 from the port 1102, the third finger or branch 108 reverts to its original shape.
Alternatively, the connector terminal of the first finger or branch 104 may be inserted into a port of an external device, and one or both of the flexible second and third fingers or branches 106, 108 may be bent to clear that finger or branch away from another port in the external device. Upon removal of the connector terminal of the first finger or branch 104 from the port, the bent finger or branch 106, 108 reverts to its original shape.
As a further alternative, the connector terminal of the third finger or branch 108 may be inserted into a port of an external device, and one or both of the flexible first and second fingers or branches 104, 106 may be bent to clear that finger or branch away from another port in the external device. Upon removal of the connector terminal of the third finger or branch 108 from the port, the bent finger or branch 104, 106 reverts to its original shape.
In this manner, the multi-head cable connector of the embodiment provides a cable connector having a plurality of flexible fingers, each of which is independently bendable yet sufficiently rigid so as to return to its original shape after bending.
Though the embodiment shows a multi-head cable connector having three flexible fingers or branches, other examples having fewer or more than three fingers or branches are also within the scope of the embodiments.
To solve the aforementioned problems, the present embodiments provide a multi-head cable connector with flexible fingers.
