The present disclosure relates to a multi-port connector, more particularly for connection to a connector of a Wi-Fi access point.
Certain governmental low power indoor (LPI) regulations require that access points for Wi-Fi 6E (802.11ax) applications have integrated antennas. One access point seeking to meet such requirements is the Mist AP45 Access Point (manufactured by Juniper Networks®), which allows for connection with an external antenna that is integrated to the access point in a secured and tamper-proof manner. Access points with external antennas or connectors for Wi-Fi 6E (802.11ax) applications aim to provide various benefits, such as improved signal propagation, e.g., for various deployments, from large public venues (LPVs) to warehouses.
Among other features, the conventional 6-port male-type connector 30 includes side buttons 32 configured to actuate release prongs that secure the connector 30 to the female-type connector 20. The buttons 32 are difficult to actuate due to their location at opposite shorter sides of the connector 30, which are obstructed by other elements of the access point 1 during installation. It is therefore difficult to disconnect the connector 30 from the female-type connector 20.
Furthermore, during installation, and more particularly when connecting a coaxial cable 50 to a contact pin assembly 34, the conductor 52 of the coaxial cable 50 is typically soldered directly at the grounding plane GP. The space needed for soldering at that location is limited, and for this reason, smaller gauge, high loss cables are used to allow for adequate soldering. This in turns leads to various disadvantages, such as extremely high loss of signal, the need for extremely short cable runs, a larger antenna to offset gain loss through the cable, or an undesirable voltage standing wave ratio leading to irregular signals.
In various exemplary embodiments, a multi-port connector includes a housing having a male-type multi-port connection configured to fit within a female-type multi-port connection. A plurality of pin conductors are located at least partially within the housing and configured to electrically connect to the female-type multi-port connection.

Various exemplary embodiments are directed to a multi-port connector 100 as shown in
The housing 102 can include any number or combination of rectilinear or curvilinear sides or outer faces. In certain configurations, the housing 102 has two opposite shorter sides or minor outer surfaces 1022 and two opposite longer sides or major outer surfaces 1023, having a substantially rectangular configuration. The housing 102 may be formed of multiple parts. For example, a top portion 1024 of the housing 102 may be attached to a bottom portion 1025 of the housing 102, e.g., using screws 1026 and/or any other suitable housing attachment mechanism, such as, but not limited to, a snap fit attachment, adhesive, welding, etc. The configuration (i.e., size, shape, number of sides, etc.) of the housing can vary as needed based on the application, the associated connector, or related device.
In some embodiments, the multi-port connector 100 includes a plurality of pin conductors 104 as shown in
In some embodiments, the multi-port connector 100 includes one or more latches 106 which extend in the proximal direction P and are configured to lock with a female-type multi-port connection when the male-type multi-port connection fits within a female-type multi-port connection.
As shown in
In certain configurations the latches 106 can include a base 1061, a first leg 1062, a deflection member 1063, a second leg 1064, and a prong 1065, as best shown in
As shown in
In some embodiments, the multi-port connector 100 includes at least one button 108. As shown in
As best shown in
In the illustrated embodiment, the latches 106 are caused to at least partially pivot toward each other, namely, toward a central axis of the multi-port connector 100. For example, the prong 1065 is made to pivot relative to the base portion 1061 of the latch 106 which is located within a groove of the housing 102. A shown in
In the illustrated embodiments, the one or more buttons 108 are located on an outer surface of the top portion 1024 of the housing 102. As a result, it is easier to actuate the one or more buttons 108 to release the one or more latches 106 when the multi-port connector 100 is connected to a female-type connector, such as, for example, the female-type connector 20 of
As illustrated in
In some embodiments, as shown in greater detail in
The cable seating 120 has a proximal first end portion 124 and that has a length L1 longer than the insertion depth D of the mount 105 (e.g., longer than a length L3 of the attachment pins 1051) in the longitudinal direction D. The cable seating 120 further has a distal second end portion 126 that can be fixed to a conductive portion 152 of a cable 150, while the conductive portion 152 passing through the cable seating 120 contacts the corresponding pin conductor 104. The cable seatings 120 can be cylindrical.
In some embodiments, the distal second end portion 126 can have a non-continuous opening, for example a crenulated opening, with a set of square-peaks separated by slots. Other shapes and configurations can also be used. One advantage of such a non-continuous outline can be to increase surface area available for a joining process. Furthermore, the irregular outline of the distal second end portion 126 can be latched on or contacted by a projection (not shown) of an inner portion of the housing 102 to prevent removal of the cable seating 120 after installation.
In various exemplary embodiments, at least a portion of the coaxial cable 150 can be fixed to the cable seating 120 through a joining process (e.g., soldering, brazing, welding, adhesive, etc.). For example, an exposed conductive portion 152 of the cable 150 can be joined to the cable seating 120. In certain applications the joining process is achieved through soldering the conductive portion 152 of the cable 150 to the sleeve 120. As noted above, the distal second end portion 126 of the sleeve 120 can have a structural feature which helps enhance a joining connection to the cable 150. Accordingly, the cable 150 and the cable seating 120 can be joined at a location spaced from the mount 105 along the conductor length.
In some embodiments, the cable seating 120 can be metallic. In other embodiments, the cable seating 120 can be non-metallic except for its distal second end portion 126. For example, the proximal first end portion 124 of the cable seating 120 can be made of plastic, while its distal second end portion 126 can be made of metal or can include a metallic material. In some configurations, the metallic distal end portion 126 can include a metal coating or metallic material applied via an adhesive. The metal of the distal end portion 122 can be suitable for soldering applications. The distal end portion 126 can also be made of or include a non-metallic material suitable for soldering applications. In some alternative embodiments, the material of the cable seating 120 can be selected to be used with a different joining process such as an adhesive connection.
In some embodiments, the cable seating 120 can form a friction fit or a snap fit with a corresponding mount 105, e.g., with the attachment pins 1051. Additionally or alternatively, the cable seating 120 can be glued to a corresponding mount 105. The mount 105 is configured to maintain the cable seating 120 secured within the mount 105. In some applications, however, a soldering or other joining connection can be made to the mount 105. For example, the attachment pins 1051 can be soldered to the cable seating 120.
During installation of a cable 150 a joining connection need not be made at the grounding plane GP which can reduce the required peripheral space for the connection, for example a soldering connection. In typical systems, extra space is needed to solder the cable, which requires a greater distance between adjacent cables and thus smaller diameter cables have to be used. In certain configurations, the thickness of the cable seating 120 can be much thinner than the space required for soldering in prior systems. Consequently, a much larger gauge, lower loss cable 150 can be used, compared to conventional systems. This in turns leads to various advantages over prior systems, such as much lower loss of signal, the ability to run much longer stretches of cable, the ability to use a smaller antenna due to the lower gain loss through the cable, and much more reliable signal levels. Examples of cables suitable for use with the multi-port connectors 100 can include, but are not limited to, ATS-100 (or other LMR-100 equivalents), ATS 195, LMR 195, or RGC-16 cables, whereas typical systems can only utilize RG 316 or equivalent cables. In some embodiments, the reduction of spacing needed to solder the cables can allow for spacing between the cables of less than 2 mm. For example between 2 mm and 0.5 mm or between 1.8 mm and 0.5 mm. In certain configurations spacing between the cables can be approximately 1 mm.
