The subject matter herein relates generally to connector assemblies, and more particularly, to latching connector assemblies.
Known connector assemblies include two connectors that mate with one another to communicate data and/or power signals between the connectors. In order to ensure that the connectors remain mated to one another, one of the connectors may include spring beams that are biased by the other connector when the connectors mate with each other. The spring beams are biased to a position that secures the connectors together. For example, the spring beams may be outwardly biased when the spring beams engage features on the other connector. The outward biasing of the spring beams increases the amount of force that is required to separate the connectors. As a result, the connectors may remain coupled in the absence of a sufficiently strong separation force that overcomes the spring beams.
One problem with the spring beams is that the beams may become fatigued over time. Repeated coupling and decoupling of the connectors requires repeated biasing of the spring beams. As the spring beams are repeatedly biased, the spring beams can weaken. The weakened spring beams may be unable to prevent the connectors from being inadvertently separated. For example, the amount of force required to separate the connectors may be decreased when the spring beams are weakened.
Coaxial connectors may include spring beams to secure the coaxial connectors in a mated relationship. When the coaxial connectors are mated, the center signal contact of each coaxial connector mates with the center signal contact of the other coaxial connector and the shields of the coaxial connectors mate with one another. As the spring beams weaken, the coaxial connectors may be unable to remain in a mated relationship and the shields and/or center signal contacts may separate from one another.
Thus, a need exists for an assembly that retains two connectors in a mated relationship and that can retain the connectors in a mated relationship after repeated coupling and decoupling of the connectors. Additionally, a need exists for an assembly that secures two coaxial connectors in a mated relationship after repeated coupling and decoupling of the coaxial connectors.
In one embodiment, a connector assembly is provided. The connector assembly includes a receptacle connector that has a housing, a lever arm, and a center contact. The housing defines an interior chamber. The lever arm is pivotally joined to the housing. The center contact is disposed within the interior chamber and is oriented along a longitudinal axis of the receptacle connector. The mating connector includes a plug body and an axial conductive member. The axial conductive member is disposed in the plug body along a center axis of the plug body. The lever arm of the receptacle connector engages the plug body of the mating connector when the plug body is received in the interior chamber and pivots relative to the housing to drive the plug body within the interior chamber and mate the axial conductive member with the center contact.
In another embodiment, a coaxial receptacle connector is provided. The receptacle connector includes a housing, a center contact, and a lever arm. The housing defines an interior chamber that extends along a longitudinal axis. The center contact is disposed in the interior chamber and is oriented along the longitudinal axis. The lever arm is pivotally joined to the housing and extends between an engagement end disposed within the housing and an actuation end disposed outside the housing. The engagement end contacts a mating connector that is loaded into the interior chamber and the actuation end is moveable to pivot the lever arm. The lever arm pivots to move the engagement end and drive the mating connector toward the center contact along the longitudinal axis.
In another embodiment, a receptacle connector is provided. The receptacle connector includes a housing, a center contact, an outer contact, and a lever arm. The housing defines an interior chamber extending along a longitudinal axis. The interior chamber receives a mating connector that includes an axial conductive member and a conductive ring extending around the axial conductive member. The center contact is disposed within the interior chamber. The outer contact extends around the center contact within the interior chamber. The lever arm is pivotally joined to the housing to engage and drive the mating connector along the longitudinal axis in the interior chamber when the mating connector is loaded into the interior chamber. The lever arm drives the mating connector toward the outer contact until the outer contact is electrically coupled with the conductive ring of the mating connector and the center contact is electrically joined with the axial conductive member of the mating connector.
The housing 106 defines an interior chamber 204 that extends along a longitudinal axis 206 from a mating face 208 of the housing 106 to a dielectric body 210. In the illustrated embodiment, the interior chamber 204 extends to an internal surface 216 of the dielectric body 210. The internal surface 216 may be an exposed front surface of the dielectric body 210 that is located within the interior chamber 204. The dielectric body 210 may include, or be formed from, a dielectric material, such as one or more polymers. The housing 106 may have a cylindrical shape such that the mating face 208 is an approximately circular ring. Alternatively, the housing 106 and/or the mating face 208 may have a different shape, such as a polygon. The mating connector 104 (shown in
A center contact 212 is disposed within the interior chamber 204. The center contact 212 is a conductive body that is oriented along the longitudinal axis 206 of the housing 106. Alternatively, the center contact 212 may not be oriented along the longitudinal axis 206. For example, the center contact 212 may be offset from the longitudinal axis 206. The center contact 212 extends through the dielectric body 210. The center contact 212 may be disposed through the middle or axial center of the dielectric body 210.
In the illustrated embodiment, an outer contact 218 is located in the interior chamber 204. The outer contact 218 may encircle the dielectric body 210 and the center contact 212 along the longitudinal axis 206. As shown in
A conductive gasket 302 extends around the dielectric body 210 at the mounting surface 300. The conductive gasket 302 may be electrically joined with the outer contact 218 (shown in
Returning to the discussion of the receptacle connector 102 as shown in
Pivot pins 224 extend through the lever arms 108. The pivot pins 224 are received in openings 226 in the housing 106 to pivotally couple the lever arms 108 to the housing 106. The pivot pins 224 define pivot axes 228 about which the lever arms 108 pivot relative to the housing 106. As described below, the engagement end 220 engages the mating connector 104 (shown in
The plug body 400 includes an axial conductive member 404 oriented along the center axis 402. Alternatively, the axial conductive member 404 may not be oriented along the center axis 402. For example, the axial conductive member 404 may be offset from the center axis 402 while still being held in the plug body 400. A dielectric body 406 encloses the axial conductive member 404 along a portion of the length of the axial conductive member 404. The dielectric body 406 includes, or is formed from, a dielectric material such as one or more polymers. A conductive jacket 412 extends around the dielectric body 406 along all or a portion of the length of the dielectric body 406. The conductive jacket 412 is a conductive body of the plug body 400 that is a conductive shield. Similar to the center and outer contacts 212, 218 (shown in
The conductive jacket 412 may terminate at a conductive ring 410 disposed at the front face 408 of the plug body 400. The conductive ring 410 may be a portion of the conductive jacket 412 that is partially bent or folded back to form the conductive ring 410. Alternatively, the conductive ring 410 may be separately formed from the conductive jacket 412 and coupled to the conductive jacket 412. The conductive ring 410 may form a flange at the front face 408 by radially projecting from the plug body 400 around the front face 408.
An insulative sheath 414 extends around the conductive jacket 412 along a portion of the length of the plug body 400. The insulative sheath 414 includes, or is formed from, a dielectric material such as one or more polymers. The insulative sheath 414 protects the conductive jacket 412 from contact with other conductive components. As shown in
In the illustrated embodiment, the lever arms 108 include projections 502 that extend from the engagement ends 220 of the lever arms 108. The projections 502 may protrude from the engagement ends 220 along extension directions 504. The extension directions 504 may be offset from the pivot pins 224 or pivot axes 228 (shown in
As shown in
The rearward movement of the engagement ends 220 and projections 502 drive the mating connector 104 along the longitudinal axis 206 toward the dielectric body 210 of the receptacle connector 102. In one embodiment, the lever arms 108 continue to pivot at least until the axial conductive member 404 of the mating connector 104 engages the center contact 212 of the receptacle connector 102 and the conductive ring 410 of the mating connector 104 engages the outer contact 218 of the receptacle connector 102. Once the axial conductive member 404 engages the center contact 212, the mating connector 104 and receptacle connector 102 can communicate data signals therebetween using the axial conductive member 404 and the center contact 212. The conductive ring 410 may engage the outer contact 218 by abutting the outer contact 218 to electrically couple the conductive ring 410 with the outer contact 218. The conductive ring 410 may then be coupled with a ground reference via the outer contact 218 or the outer contact 218 may be coupled with the ground reference via the conductive ring 410.
In the illustrated embodiment, the lever arms 108 lock into position when the mating connector 104 and receptacle connector 102 mate with one another as shown in
In order to decouple the mating connector 104 and receptacle connector 102, the lever arms 108 may be pivoted in decoupling directions 602. The decoupling directions 602 are oriented opposite of the engagement directions 600 such that the actuation ends 222 of the lever arms 108 are moved away from the mating face 208 of the housing 106 and toward the mounting surface 300 of the housing 106. As the lever arms 108 move in the decoupling directions 602, the compressive force is no longer applied to the conductive ring 410 and the mating connector 104 is no longer driven toward the center contact 212. As a result, the axial conductive member 404 may decouple from the center contact 212 and the conductive ring 410 may no longer abut the outer contact 218, thereby decoupling the mating connector 104 from the receptacle connector 102.
While the embodiment shown in the attached Figures shows and describes the conductive ring 410 providing a radial flange that is engaged and driven by the pivoting lever arms 108, alternatively the lever arms 108 may engage a different component or portion of the mating connector 104. For example, the mating connector 104 may include a different feature or component that radially projects from the mating connector 104 and is engaged and driven by the lever arms 108. In another example, the mating connector 104 may include recesses or notches into which the engagement ends 220 of the lever arms 108 are received. For example, the projections 502 may be received in notches in the mating connector 104 in order to engage and drive the mating connector 104 along the longitudinal axis 206 of the receptacle connector 102.
Additionally, while the receptacle connector 102 is shown as being capable of being mounted to a panel, alternatively the mating connector 104 may be mounted to a panel. For example, the mating connector 104 may include a mounting flange similar to the mounting flange 200 (shown in
