The present invention relates to a waveguide connector assembly and more particularly to a waveguide connector assembly with a waveguide connector and a moveable sleeve.
Waveguide connectors provide an electrical and mechanical connection between a wireless transmitter/receiver and an antenna. Current waveguide connectors provide this connection through the use of flanges and a plurality of fasteners. The waveguide connection must be disassembled and assembled repeatedly and thus requires the use of specialized tools and many small parts. This configuration presents a problem for waveguide connectors mounted on difficult to reach locations such as tall buildings and antenna towers. Accordingly, there is a need for a quick connect waveguide assembly.
A waveguide connector assembly is disclosed. The waveguide connector assembly includes a waveguide connector having a first end, a second end opposite the first end, and a body having a length that extends axially between the first end and the second end, the body having an interior surface and an exterior surface, the waveguide connector being configured to receive a waveguide at the first end. The waveguide connector assembly further includes a movable sleeve having a first end, a second end opposite the first end, a body extending axially between the first end and the second end, and an actuating surface, the movable sleeve being configured to slide axially along the exterior surface of the waveguide connector, the actuating surface being configured to prevent axial movement of the waveguide when the movable sleeve is in an actuating position.
An antenna system is disclosed. The antenna system includes an antenna. The antenna system further includes a waveguide. The antenna system further includes a connector assembly. The connector assembly further includes a waveguide connector having a first end, a second end opposite the first end, and a body having a length that extends axially between the first end and the second end, the body having an interior surface and an exterior surface. The waveguide connector is configured to receive the waveguide, and a movable sleeve having a first end, a second end opposite the first end, a body extending axially between the first end and the second end, and an actuating surface. The movable sleeve is configured to slide axially along the exterior surface of the waveguide connector. The actuating surface is configured to prevent axial movement of the waveguide when the movable sleeve is in the actuating position. The antenna system further includes a bracket configured to couple the connector assembly to the antenna.
A method of adjusting the polarizations of a waveguide connector assembly is disclosed. The method of adjusting the polarizations of a waveguide connector assembly including sliding a movable sleeve on a waveguide connector away from an actuating position along an axis which causes an unlocking of a waveguide, the unlocking allowing free movement of the waveguide within the waveguide connector. The method of adjusting the polarizations of a waveguide connector assembly further including rotating a waveguide either 45 degrees or 90 degrees. The method of adjusting the polarizations of a waveguide connector assembly further including sliding the movable sleeve towards the actuating position along the axis which causes a locking of the waveguide, the locking not allowing free movement of the waveguide within the waveguide connector.

Waveguide connector 101 may have a first end 103, a second end 105 opposite first end 103, a body 107 having a length that extends along an axis A′ between first end 103 and second end 105, an exterior surface 111, and a mating surface 117. Waveguide connector 101 may be configured to receive waveguide 141 at first end 103 through antenna 101 and through bracket 171. Waveguide 141 may have one or more nesting surfaces 151 to aid in waveguide connector 101 receiving waveguide 141.
Movable sleeve 121 may be configured to slide axially on exterior surface 111 of waveguide connector 101. Movable sleeve 121 may have an actuating surface configured to prevent axial movement of waveguide 141 when movable sleeve 121 is in an actuating position. As used herein, “actuating position” refers to an axial position of movable sleeve 121 relative to waveguide connector 101 which causes waveguide connector 101 to engage with waveguide 141.
Bracket 171 may be configured to couple to antenna 161 and likewise be configured to couple to waveguide 101 via mating surface 117. In its fully assembled form or configuration, waveguide 141 is received by waveguide connector 101, antenna 161 is coupled to waveguide connector via bracket 171, and movable sleeve 121 secures waveguide 141 to waveguide connector 101.
A user may remove waveguide 141 from antenna system 100, without the usage of tools, by sliding movable sleeve 121 away from the actuating position and sliding waveguide 141 axially away from waveguide connector 101. A user may attach waveguide 141 to antenna 161 and waveguide connector 101, without the usage of tools, by sliding movable sleeve 121 away from the actuating position, sliding waveguide 141 axially towards and through antenna 161 and into waveguide connector 101, and then sliding movable sleeve 121 back into the actuating position.
A user may also adjust the polarity of antenna system 100, without the usage of tools, by sliding movable sleeve 121 away from the actuating position, sliding waveguide 141 axially away from antenna 161, rotating waveguide 141 (e.g., rotating by 45 degrees or 90 degrees), sliding waveguide 141 axially towards and through antenna 161 and into waveguide connector 101, and then sliding movable sleeve 121 back into the actuating position.
Antenna 161 is depicted as a parabolic dish, however, other configurations such as a horn, an open aperture, a reflector, or a subreflector may be used interchangeably according to various embodiments.
Waveguide connector 101 has a first end 103, a second end 105 opposite first end 103, and a body 107 having a length that extends along an axis A′ between first end 103 and second end 105. Body 107 of waveguide connector 101 has an interior surface 109 and an exterior surface 111. Body 107 may have various cross sectional geometries, for example, cylindrical, rectangular, square, or otherwise rotational symmetric.
In some embodiments, interior surface 109 of body 107 is symmetrical in cross section throughout the length of body 107. In other embodiments, the cross sectional geometry of waveguide connector 101 may vary along the length of body 107.

As shown in
In some embodiments, movable sleeve 121 may have the same cross sectional geometry as waveguide connector 101. In some embodiments, movable sleeve 121 may have a different cross sectional geometry as waveguide connector 101. In some embodiments, movable sleeve 121 may have a cross sectional geometry that varies along the length of movable sleeve 121.
In some embodiments, aperture 113 couples to bearing 115 by having a retainer coupled to exterior surface 111 of waveguide connector 101. The retainer may be coupled to exterior surface 111 via a brazing, an adhesive, or fastening using fasteners. In some embodiments, aperture 113 couples to bearing 115 by having a retainer coupled to interior surface 109 of waveguide connector 101. The retainer may be coupled to interior surface 109 by a brazing, an adhesive, or fastening using fasteners.
Bearing 115 may be coupled to a force provider to provide a restoring force urging it away from a nesting position. The force provider may be a mechanical spring, a pneumatic spring, a hydraulic spring, a magnetic spring, or an electromagnetic spring. In some embodiments, aperture 113 may be similarly configured to couple to detents, plungers, compressible rings, partial rings, washers, buttons, pins, or stops.
In some embodiments, actuating surface 131 may be configured to prevent radial movement of bearing 115 when actuating surface 131 covers aperture 113. When movable sleeve 121 is brought to the actuating position, actuating surface 131 may depress bearing 115 and force bearing 115 radially inward engaging the nesting surface on the waveguide 141. In some embodiments, bearing 115 may be forced away from the nesting surface on the waveguide 141 by a force provider coupled to waveguide connector 101 when the movable sleeve 121 is not in the actuating position, to facilitate disengagement of waveguide 141 from the waveguide connector 101. The force provider may be a mechanical spring, a pneumatic spring, a hydraulic spring, a magnetic spring, or an electromagnetic spring. It should be understood that any configurations of detents, plungers, compressible rings, partial rings, washers, buttons, pins, or stops may be substituted for bearing 115 discussed in any of the embodiments.
In some embodiments, interior surface 109 of waveguide connector 101 and/or an exterior surface of waveguide 141 may have a coating or a plating for reducing wear or friction caused by the insertion and removal of waveguide 141. In some embodiments, exterior surface 111 of waveguide connector 101 and/or an interior surface of movable sleeve 121 may have a coating or plating for reducing wear or friction caused by the sliding of movable sleeve 121 over exterior surface 111 of waveguide connector 101.
In some embodiments, any combination of the surfaces of waveguide connector 101, movable sleeve 121, or waveguide 141, may have a coating or a plating for enhancing its resistance to corrosion. In some embodiments, any combination of the surfaces of waveguide connector 101, movable sleeve 121, or waveguide 141, may have a coating or a plating for enhancing its electrical properties.
Waveguide connector 201 is similar to waveguide connector 101 depicted in
To better facilitate a user's interaction with second movable sleeve 241, second movable sleeve 241 may also have a gripping surface 249. Gripping surface 249 may be configured to aid a user in moving movable sleeve 241 away and towards an actuating position. In some embodiments, gripping surface 249 may be configured to aid a user in moving movable sleeve 241 either away or towards an actuation position. In some embodiments, gripping surface 249 may be a flange extending radially outward from body 247. Gripping surface 249 may be formed throughout an exterior surface of body 247. In some embodiments, gripping surface 249 may be formed only partially on the exterior surface of body 247. In some embodiments, gripping surface 249 may be in the form of a protrusion on the exterior surface of body 247.
Without tools, a user may slide a movable sleeve (e.g. movable sleeve 121) away from an actuating position (Step 501). When the movable sleeve is moved away from the actuating position a waveguide (e.g. waveguide 141) may be decoupled from a waveguide connector (e.g. waveguide connector 101), thereby allowing axial movement of the waveguide relative to the waveguide connector. In some embodiments, the waveguide may be free to rotate within the waveguide connector when the waveguide is decoupled from the waveguide connector.
A user may then rotate the waveguide either 45 degrees or 90 degrees (Step 503). In some embodiments, the waveguide may be removed from the waveguide connector prior to a user rotating it. In some embodiments, the waveguide may be still within the waveguide connector prior to a user rotating it. The angle the waveguide is to be rotated is determined by the desired resulting change in polarity.
Without tools, a user may slide the movable sleeve towards the actuating position (Step 505). When the movable sleeve is moved towards the actuating position the waveguide may be coupled to the waveguide connector, thereby preventing axial movement of the waveguide relative to the waveguide connector. In some embodiments, the waveguide may be free to rotate within the waveguide connector when the waveguide is coupled to the waveguide connector. In some embodiments, Step 505 may be performed by a force provider. The force provider may be a mechanical spring, a pneumatic spring, a hydraulic spring, a magnetic spring, or an electromagnetic spring.
