[0029] In an aspect, the present disclosure introduces a connecting unit installed on a connector that terminates a cable. However, the present connecting unit could equally be installed on a component adapted to receive a cable terminated with a connector, such as for example a SFP cage.

[0030] The connecting unit comprises a casing and a connector. The casing may be adapted for example to receive a cable, such as an electric or optic cable. The connector may consist of one or several connectors, either of the electric or optic type. An example of an electric connector is a HDMI
connector. The connector directly or ultimately connects with the cable, via an electric of optic connection. The connector may be located within or in periphery of the casing. The connecting unit further comprises a latch mechanism mounted on the casing. The latch mechanism comprises an engaging extremity and a disengaging extremity.

[0031] Although the following description refers to HDMI connectors and to SFP cages, the present connecting unit with latch mechanism is not limited to such aspects. Reference to HDMI and SFP are for example only, and the present connecting unit may be used with any electrical or optic standard.

[0032] Referring now to the drawings, Figures 1 to 3 provide specification examples for a component that may connect with the present connecting unit. More particularly, Figures 1 to 3 depict various views of a SFP
cage, providing a retaining member.

[0033] In more details, Figure 1 provides several views of a SFP cage adapted to receive a connecting unit with latch mechanism. A SFP cage 100, adapted to receive a connecting unit with latch mechanism, is shown in a front 3440657.1 perspective view (100a), a side elevation view (100b), a top view (100c), another side elevation view (100d), a bottom view (100e), a front elevation view (1000 and a rear elevation view (100g). Quotes, dimensions, and materials illustrated in this and in the following Figures are provided as examples only. The present connecting unit is not limited to such dimensions and materials.

[0034] Figure 2 is a series of detailed views of a SFP cage top adapted to receive an HDMI connecting unit with the present latch mechanism.
The SFP cage 100 comprises a top 102, which is readily visible in views 100a and 100c of Figure 1. An underside of the top 102 shows threaded pins 104 for assembly of the top 102 with other components of the SFP cage 100. Ejectors 106 are also shown. Alphanumerical fields 108 show a part number and a manufacturing date of the SFP cage 100.

[0035] Figure 3 is a series of detailed views of a SFP cage bottom adapted to receive an HDMI connecting unit with the present latch mechanism.
The SFP cage 100 comprises a bottom 110, which is readily visible in view 100e of Figure 1. The bottom 110 comprises a hole 112 configured to match the threaded pins 104 of the top 102, for assembly of the SFP cage 100, for example by means of screws (not shown).

[0036] Figure 4 depicts several views of an ejection mechanism. An ejection mechanism 120 is in part inserted within the SFP cage 100, with a triggering end 122 protruding at the front of the SFP cage 100. A distal end 124 of the ejection mechanism 120 acts upon a latch 126, visible on Figures 1 and 3, for releasing the SFP cage 100 from a chassis (not shown). Operation of the ejection mechanism 120 and of the latch 126 is further described in United States Application Serial Number 13/081,862, the disclosure of which is incorporated herein in its entirety.

[0037] Figures 5 to 8 depict disassembled components of a connecting unit example. More specifically, Figure 5 depicts a series of detailed views of an HDMI connecting unit top booth. Various views of a top 3440657.1 booth 130 are provided, including a top perspective view 130a, a side elevation view 130b, a top cutaway view 130c, another side elevation view 130d, a cutaway side elevation view 130e, a top view 130f and a rear view 130g.

[0038] Figure 6 is a series of detailed views of an HDMI connecting unit bottom booth. Various views of a bottom booth 140 are provided, including a perspective bottom view 140a, a side elevation view 140b, a top cutaway view 140c, another side elevation view 140d, a cutaway side elevation view 140e, a bottom view 140f, a rear view 140g and a front view 140h. Pins 132 of the top booth 130 are adapted to mate with recesses 142 of the bottom booth 140. Holes 144 allow insertion of screws (not shown) through the bottom booth 140 and into holes 134 of the top booth. Together, the HDMI connecting unit top booth 130 and bottom booth 140 form a casing configured to enclose a standard HDMI connector (not specifically shown) and to receive an HDMI
Plug Lock (shown in a next Figure). In turn, the HDMI Plug Lock is configured to provide a solid attachment of the HDMI connector to the SFP cage 100.

[0039] Reference is now made more particularly to Figure 7, which depicts a series of views of an HDMI Plug Lock to be affixed to the HDMI
connecting unit top booth of Figure 5. A plug lock 150 comprises an engaging extremity 152 and disengaging extremity 154 embodied a single actuator. An axis 158 of the plug lock 150 is made to insert within slots 138 of the top booth 130. When the plug lock 150 is mounted to the top booth 130, the engaging extremity 152 is placed within a void 139 of the top booth 130. A bracket 148 of the bottom booth 140 maintains the axis 158 in place when the top and bottom booths are assembled. The engaging extremity 152 has a projection 155 adapted to engage a retaining member of a component to which the connecting unit is to be connected to. For example, in Figures 1 and 2, the retaining member is a lip 156 provided at the front of the top 102 of the SFP
cage 100. However, the present connecting unit is not limited to operation with only such a retaining member. Many variants of retaining members could be used, without departing from the present connecting unit.

[0040] Figure 8 depicts views of an HDMI Plug Spring to be used with the HDMI connecting unit top booth of Figure 5 and with the HDMI Plug Lock of Figure 7. A resilient mechanism 160, which is folded along lines 162 and 164, is configured to resist actuation of the disengaging extremity 154. A T-shaped end 166 of the resilient mechanism 160 is made to insert into a similarly shaped recess 136 within the top booth 130. Upon application on the engaging extremity 152 of a pressure sufficient to overcome a resistance presented by the resilient mechanism 160 on the disengaging extremity 154, the disengaging extremity 154 engages pivotal movement of the engaging extremity 152 around the axis 158, resulting in disengagement of the projection 155 of the engaging extremity 152 from the component to which the connecting unit is connected.

[0041] Those of ordinary skill in the art will realize that the description of the connecting unit with latch mechanism are illustrative only and are not intended to be in any way limiting. Other embodiments will readily suggest themselves to such persons with ordinary skill in the art having the benefit of the present disclosure. Furthermore, the disclosed connecting unit may be customized to offer valuable solutions to existing needs and problems of connecting electric/optic cables, electric/optic connectors, and electric/optic components.

[0042] In the interest of clarity, not all of the routine features of the implementations of the connecting unit are shown and described. It will, of course, be appreciated that in the development of any such actual implementation of the connecting unit, numerous implementation-specific decisions may need to be made in order to achieve the developer's specific goals, such as compliance with application-, system-, network- and business-related constraints, and that these specific goals will vary from one implementation to another and from one developer to another. Moreover, it will be appreciated that a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking of engineering for 3440657.1 those of ordinary skill in the field of connectors having the benefit of the present disclosure.

[0043] Although the present disclosure has been described hereinabove by way of non-restrictive, illustrative embodiments thereof, these embodiments may be modified at will within the scope of the appended claims without departing from the spirit and nature of the present disclosure.
