The subject matter herein generally relates to electrical connectors and, more particularly, to an electrical connector having a latching mechanism for securing the electrical connector to a mating connector.
Various types of latches have been proposed for electrical connectors such as external mini-SAS connectors. The electrical connectors are inserted into corresponding receptacles to communicate data. Existing connectors include a mating end that is plugged into the receptacle. A corresponding latching assembly for the connector latchingly engages with the receptacle to securely hold the mating end of the connector in the receptacle. The latching assembly latches with the receptacle by raising hooks proximate the mating end of the connector, inserting the mating end into the receptacle, and then lowering the hooks to latch with holes in the receptacle. The connector is then securely engaged with the receptacle. In order to unlatch the latching assembly from the receptacle, the hooks are raised out of the holes in the receptacle. The mating end of the connector is then removed from the receptacle.
Existing latching assemblies are configured to raise and lower the hooks of the latching assemblies, relative to the receptacles, by actuating a tab or other handle on a latching assembly. The hooks in some latching assemblies are raised when the handle is pushed (referred to as “push-only latching assemblies”).
The hooks in other latching assemblies are raised when the handle is pulled (referred to as “pull-only latching assemblies”). As a result, a user of the latching assemblies cannot switch between pushing and pulling the handles of the latching assemblies to unlatch the hooks.
The inability of existing latching assemblies to permit latching and unlatching of the assemblies with corresponding receptacles by only pushing or pulling the handle of a latching assembly (but not both or in any other direction) can make it difficult to use the latching assemblies in certain spaces. For example, the location of certain receptacles can make grasping and pulling the handle of a latching assembly to latch the latching assembly with the receptacle very difficult. The opposite situation may also be true—certain locations of a receptacle can make it difficult to push a handle of a latching assembly to latch or unlatch the latching assembly with the receptacle. In these situations, only one of the push-type or pull-type latching assemblies may be used and the other type of latching assembly may be too difficult to use. In other situations, it can be difficult to push or pull a handle of a latching assembly to latch or unlatch the latching assembly with the receptacle. As a result, many latching assemblies become too difficult to use in certain spaces.
Moreover, many latching assemblies provide mechanisms for latching with the receptacle once the handle of the latching assembly is released. Yet, these latching assemblies frequently include additional parts and components in order to latch the latching assembly with the receptacle. These additional parts and components add to the cost and complexity of the latching assemblies.
Thus, a need exists for a latching assembly for an electrical connector that provides the option of unlatching the latching assembly from a receptacle by multiple moving actions, including pushing or pulling a handle or tab along a longitudinal direction of the latching assembly, or moving the handle or tab downwards with respect to the latching assembly.
In one embodiment, a latching assembly for an electrical connector is provided. The latching assembly includes a latch and an actuator. The latch includes a latching end configured to latch with a receptacle assembly. The actuator is movable in both a push direction and a pull direction. The actuator raises the latching end to unlatch the latching end from the receptacle assembly when the actuator is pushed in the push direction and when the actuator is pulled in the pull direction.
Optionally, the latch includes a pair of oppositely sloped ramps. The actuator slides along a first one of the ramps to raise the latching end and unlatch the latching end from the receptacle assembly when the actuator is pushed in the push direction. The actuator slides along a second one of the ramps to raise the latching end from the receptacle assembly when the actuator is pulled in the pull direction.
In another embodiment, an electrical connector is provided. The electrical connector includes a housing and a latching assembly. The housing extends between a mating end and a terminating end. The mating end is configured to mate with a receptacle assembly. The latching assembly includes a latch and an actuator. The latch includes a plurality of ramps and a latching end. The latching end is configured to latch with a receptacle assembly. The actuator is movable in a push direction and in a pull direction. The actuator contacts a first one of the ramps to raise the latching end and unlatch the latching end from the receptacle assembly when the actuator is pushed in the push direction. The actuator contacts a second one of the ramps to raise the latching end and unlatch the latching end from the receptacle assembly when the actuator is pulled in the pull direction.
In another embodiment, another latching assembly for an electrical connector is provided. The latching assembly includes a housing, a latch, and an actuator. The housing extends along a longitudinal axis of the electrical connector and terminates at a mating end. The mating end is configured to be inserted into a receptacle assembly. The latch is connected to the housing. The latch includes a latching end configured to latch with the receptacle assembly. The actuator is coupled to the housing between the latch and the housing. The actuator is movable in a push direction, a pull direction, and a downward direction. The downward direction is orthogonal to the push and pull directions. The latching end unlatches from the receptacle assembly when the actuator is pushed in the push direction, when the actuator is pulled in the pull direction, and when the actuator is moved downward in the downward direction.
The latching assembly 104 latches to the receptacle assembly 110 to secure the electrical connector 102 to the receptacle assembly 110 once the electrical connector 102 is inserted into the receptacle assembly 110. The latching assembly 104 may be unlatched from the receptacle assembly 110 in order that the mating end 108 of the electrical connector 102 may be removed from the receptacle assembly 110.
While
The housing 136 includes an edge 128 proximate the terminating edge 106 of the electrical connector 102. The edge 128 provides a fulcrum about which the actuator 132 may pivot when the actuator 132 is pushed in a downward direction 124 proximate the actuator handle 156. The downward direction 124 is orthogonal to the longitudinal axis of the electrical connector 102 and to the push and pull directions 114 and 116.
A latch driving member 138 of the actuator 132 is moved in the push and pull directions 114 and 116 as the actuator 132 is pushed and pulled in the push and pull directions 114 and 116. The movement of the latch driving member 138 in both the push and pull directions 114 and 116 unlatches a latching end 146 of the latch 130 from the receptacle assembly 110 (shown in
Thus, moving the actuator 132 proximate the actuator handle 156 in the push direction 114, the pull direction 116 and the downward direction 124 raises the latching end 146 of the latch 130 so that the mating end 108 of the electrical connector 102 can be inserted into or removed from the receptacle assembly 110 (shown in
A latch disengagement assembly 172 of the latch 130 includes a pair of oppositely sloped ramps 142 and 144 separated by a slot 140. Once assembled, the latch driving member 138 is located between the ramps 142 and 144 and between the slot 140 and the housing 136.
The latching assembly 104 is assembled so that the latch driving member 138 is in the channel 134 of the housing 102 between a pair of pull stops 148 and a push stop 150. In an exemplary embodiment, the pull and push stops 148 and 150 define protrusions that extend upwards from the channel 134 in the housing 102. The pull and push stops 148 and 150 limit the longitudinal movement of the latch driving member 138 (and thus the actuator 132) along the push and pull directions 114 and 116.
The latch 130 is secured to the housing 102 by inserting a pair of mounting holes 152 in the latch 130 over a pair of mounting pins 154 extending upwards from the housing 102. Once the latch 130 is secured to the housing 102 over the actuator 132, the actuator 132 may be pushed in the push direction 114 and pulled in the pull direction 116 by pushing and pulling on a handle 156 of the actuator 132.
As the latch driving member 138 moves in the pull direction 116, the latch driving member 138 contacts and slides along the first ramp 142 of the latch 130. As the latch driving member 138 slides along the first ramp 142 of the latch 130, the first ramp 142 is raised upwards. As the first ramp 142 is raised upwards, the latch 130 flexes about the mounting pins 154 and the latching end 146 is raised. Once the latching end 146 is raised, the latching assembly 104 unlatches from the holes 122 in the receptacle assembly 110 (shown in
When the actuator 132 is then released, the latch 130 tends to straighten and force the first ramp 142 downwards towards the latch driving member 138 of the actuator 132. The slope of the first ramp 142 may help move the latch driving member 138 (and thus the actuator 132) in the push direction 114 to a neutral position between the slot 140 and the housing 136, and between the two ramps 142 and 144 (shown in
Similar to the pull stops 148, the push stop 150 may limit the distance that the latch driving member 138 (and thus the actuator 132) can move in the push direction 114.
Similar to releasing the actuator 132 after movement in the pull direction 116, releasing the actuator 132 after movement in the push direction 114 allows the latching end 146 of the latch 130 to lower and latch with the holes 122 in the receptacle 110. Once the actuator 132 is then released, the latch 130 straightens and forces the second ramp 144 downward. As the second ramp 144 is forced downward, the slope of the second ramp 144 moves the latch driving member 138 (and thus the actuator 132) in the pull direction 116 to the neutral position between the slot 140 and the housing 136, and between the two ramps 142 and 144 (shown in
Also similar to releasing the actuator 132 after pulling the actuator 132 in the pull direction 116 and pushing the actuator 132 in the push direction 114, the latching end 146 of the latch 130 lowers and latches with the holes 122 in the receptacle 110 after the actuator 132 is released after being moved in the downward direction 124. After moving and releasing the actuator 132 proximate the actuator handle 132 in the downward direction 124, the latch 130 straightens and forces the latching end 146 downward.
In operation, the centering beams 160 contact a first side 168 of the lateral extensions 162 of the channel 134 when the actuator 158 is pushed in the push direction 114. As the actuator 158 is pushed in the push direction 114 to raise the latching end 146 of the latch 130 (shown in
Conversely, as the actuator 158 is pulled in the pull direction 116, the centering beams 160 flex against a second side 170 of the lateral extensions 162. When the actuator 158 is released, the centering beams 160 straighten and force the actuator 158 back towards the push direction 114 until the actuator 158 has returned to the neutral position (shown in
The T-shape of the centering beams 166 reduces the amount of travel required by the actuator 164 in the push direction 114 before the centering beams 166 contact the first side 176 of the lateral extensions 162 of the channel 134. Additionally, the centering beams 166 reduce the amount of travel required by the actuator 164 in the pull direction 116 before the centering beams 166 contact the second side 178 of the lateral extensions 162. By reducing the amount of travel required by the actuator 164 before the centering beams 166 contact the first or second sides 176, 178 of the lateral extensions 174, the centering beams 166 may create a greater force to return the actuator 164 to the neutral position (shown in
