The subject matter herein relates generally to electrical connectors, and more particularly, to a connector having a contact organizer.
With the ongoing trend toward smaller electrical components such as processors used in computers, routers, switches, and the like, electrical connectors continue to become smaller. As connectors become smaller, the contacts used in the connectors also become smaller. Smaller contacts are more easily bent, buckled and otherwise damaged during handling of the connectors. For example, the contacts can be more easily bent during shipping of the connectors. The contacts also are more easily bent and buckled during mounting of the connectors to circuit boards and other devices. For example, the contacts may buckle during seating of a connector in a circuit board if the contacts are not properly aligned with respect to the circuit board.
Thus, a need exists for connectors with smaller contacts that are better protected from damage during handling and mounting of the connectors. Meeting such a need can allow for the size of the contacts and the connectors to continue to decrease while protecting the contacts, from mechanical damage.
In one embodiment, a connector system includes a connector assembly and a contact organizer. The connector assembly includes a mounting end and a plurality of contacts protruding from the mounting end. The contact organizer includes a top side, a bottom side and a plurality of channels extending between the top and bottom sides. The contact organizer is movable with respect to the connector assembly between a supporting position and a seated position. When the contact organizer is in the supporting position, the contacts at least partially extend through the channels. When the contact organizer is moved to the seated position, the contact organizer is moved toward the mounting end of the connector assembly until the top side of the contact organizer engages the mounting end.
In another embodiment, another connector system includes a connector assembly and a contact organizer. The connector assembly includes a mounting end and a plurality of chicklets each holding a plurality of contacts protruding from the mounting end. The connector assembly is configured to be mounted to a circuit board. The contact organizer extends between opposing top and bottom sides and includes a plurality of channels extending between the top and bottom sides. The contact organizer receives the contacts from the chicklets. The contacts slide through the cavities to mate with the circuit board.
In another embodiment, a contact organizer is configured to receive contacts protruding from a mounting end of a connector assembly. The contact organizer includes a body having a top side, a bottom side opposite to the top side, and a plurality of channels extending between the top and bottom sides. The channels are configured to receive the contacts and are oriented to align the contacts with respect to cavities in the circuit board. The contact organizer is movable with respect to the connector assembly during mating with the circuit board between a supporting position and a seated position. When the contact organizer is in the supporting position, the contacts at least partially extend through the channels. When the contact organizer is moved to the supporting position, the contact organizer is moved toward the mounting end of the connector assembly until the top side engages the mounting end.
The connector assembly 100 includes a mounting end 110 from which the ground and signal contacts 106, 108 protrude. For example, each of the chicklets 104 may include a corresponding part of the mounting end 110. The mounting end 110 may define the mounting interface of the connector assembly 100. The mounting end 110 generally faces the circuit board 200 (shown in
In the illustrated embodiment, the contact organizer 102 is shown in a supporting position. The ground and signal contacts 106, 108 are partially inserted into and supported by the contact organizer 102 through a top side 118 of the contact organizer 102. The ground and signal contacts 106, 108 for a plurality of the chicklets 104 are inserted into, and supported by, a single contact organizer 102. In the supporting position, a gap 112 is provided between the contact organizer 102 and the mounting end 110 of the connector assembly 100. Alternatively, the top side 118 is located proximate to the mounting end 110 of the connector assembly 100 such that at least a portion of the mounting end 110 directly contacts or engages a portion of the top side 118. A portion of the ground contacts 106 may protrude from a bottom side 116 of the contact organizer 102 that opposes the top side 118. The signal contacts 108 do not protrude from the bottom side 116, or may protrude from the bottom side 116 by a distance that is less than the distance that the ground contacts 106 protrude from the bottom side 116. The bottom side 116 is the side of the contact organizer 102 that directly contacts or engages the circuit board 200 (shown in
In the supporting position, the ground and signal contacts 106, 108 are supported by the contact organizer 102. For example, only a portion of the ground and signal contacts 106, 108 extend beyond the bottom side 116 of the contact organizer 102, such that a substantial portion of the ground and signal contacts 106, 108 are surrounded by, and thus protected by, the contact organizer 102. Optionally, the contact organizer 102 may entirely surround the distal ends of the ground and/or signal contacts 106, 108 to protect the ground and signal contacts 106, 108. Without the contact organizer 102, a greater portion of the ground and signal contacts 106, 108 would be exposed and thus more susceptible to bending or damage during handling, storage or shipping of the connector assembly 100. By inserting the ground and signal contacts 106, 108 into the contact organizer 102, the contact organizer 102 can provide additional mechanical support or stability to the ground and signal contacts 106, 108 prior to seating the connector assembly 100 on the circuit board 200.
The circuit board 200 includes a plurality of the signal contact cavities 202 and a plurality of the ground contact cavities 204. While the signal and ground contact cavities 202, 204 are shown as completely extending through the circuit board 200, in an alternative embodiment one or more of the signal and ground contact cavities 202, 204 partially extend through the circuit board 200. Each of the signal and ground contact cavities 202, 204 receives a corresponding one of the signal and ground contacts 108, 106 when the connector assembly 100 is in a seated position with respect to the circuit board 200, as shown in
The contact organizer 102 includes a plurality of signal contact channels 206 and a plurality of ground contact channels 208. Each of the signal and ground contact channels 206, 208 extend between the top and bottom sides 118, 116 of the contact organizer 102. In the illustrated embodiment, the signal contact channels 206 extend between a common top side opening 210 on the top side 118 and a plurality of bottom side openings 212 on the bottom side 116. Alternatively, each of the signal contact channels 206 extends between a single top side opening 210 and a single bottom side opening 212. In another embodiment, each of the signal contact channels 206 extends between a plurality of top side openings 210 and a single bottom side opening 212. The signal contact channels 206 receive the signal contacts 108 through the top side openings 210.
In the illustrated embodiment, the ground contact channels 208 extend between a common top side opening 214 on the top side 118 and a plurality of bottom side openings 216 on the bottom side 116. Alternatively, each of the ground contact channels 208 extends between a single top side opening 214 and a single bottom side opening 216. In another embodiment, each of the ground contact channels 208 extends between a plurality of top side openings 214 and a single bottom side opening 216. The ground contact channels 208 receive the ground contacts 106 through the top side openings 214.
In the illustrated embodiment, at least part of the gap 112 between the top side 118 of the contact organizer 102 and the mounting end 110 of the connector assembly 110 remains as the connector assembly 100 is seated in the circuit board 200 when the signal contacts 108 are initially inserted in the signal contact cavities 202. For example, at least a portion of the contact organizer 102 does not directly contact or engage the mounting end 110 when the connector assembly 100 is seated in the circuit board 200 sufficiently far such that the signal contacts 108 are proximate to the circuit board 200 just prior to being inserted into the signal contact cavities 202.
The contact organizer 102 moves relative to the ground and signal contacts 106, 108 as the connector assembly 100 is mounted to the circuit board 200. For example, the contact organizer 102 may slide along the ground and signal contacts 106, 108 as the connector assembly 102 is seated in the circuit board 200 beyond the position shown in
In one embodiment, the contact organizer 102 improves signal integrity of the signal contacts 108 by controlling system impedance and by reducing crosstalk between the signal contacts 108. The contact organizer 102 may control the impedance of the connector system 10 (shown in
The contact organizer 102 may be arranged as a plurality of strips 606 that each extends along the longitudinal direction 602 between the opposing ends 608, 610. Each strip 606 includes a plurality of the signal and ground contact cavities 202, 204. In the illustrated embodiment, the signal contact cavities 202 extend through the protrusions 600 in each strip 606. In another embodiment the ground contact cavities 204 extend through the protrusions 600. In another embodiment, neither the signal nor the ground contact cavities 202, 204 extends through the protrusions 600. The strips 606 may be arranged such that each strip 606 corresponds to one of the chicklets 104 (shown in
