APPARATUSES AND METHODS FOR INSTALLING ELECTRICAL CONTACTS INTO A CONNECTOR HOUSING

BACKGROUND

Installing electrical contacts into a connector housing is time consuming, difficult to perform properly, and tiring for the operator. More specifically, it may be difficult to properly position an electrical contact relative to a socket of the connector housing and maintain the electrical contact in coaxial alignment with the socket of the connector housing while the electrical contact is biased into the socket. Additionally, the operator must not under-advance or over-advance an insertion tool into the socket when biasing an electrical contact into a socket of a connector housing, which is difficult to achieve with conventional electrical contact insertion tools and methods.

SUMMARY

Accordingly, apparatuses and methods, intended to address at least the above-identified concerns, would find utility.

The following is a non-exhaustive list of examples, which may or may not be claimed, of the subject matter according the present disclosure.

One example of the present disclosure relates to an apparatus for installing at least one electrical contact into a connector housing. The apparatus comprises a base configured to fixedly support the connector housing. Additionally, the apparatus comprises an alignment guide extending from the base and having a central axis. With the connector housing fixedly supported by the base, the alignment guide is configured to be parallel to an insertion axis of a socket of the connector housing. The apparatus also comprises a carrier translatably and pivotally coupled with the alignment guide. With the connector housing fixedly supported by the base, the carrier is movable parallel to the insertion axis of the socket of the connector housing. The apparatus further comprises a tool holder coupled to the carrier. The tool holder has a working axis, only one degree of freedom relative to the carrier, and only three degrees of freedom relative to the base.

Another example of the present disclosure relates to a system for installing at least one electrical contact into a connector housing. The system comprises a base configured to fixedly support the connector housing. Additionally, the system comprises an alignment guide extending from the base and having a central axis. With the connector housing fixedly supported by the base, the alignment guide is configured to be parallel to an insertion axis of a socket of the connector housing. The system also comprises a carrier translatably and pivotally coupled with the alignment guide. With the connector housing fixedly supported by the base, the carrier is movable parallel to the insertion axis of the socket of the connector housing. The system further comprises a tool holder coupled to the carrier. The tool holder has a working axis, only one degree of freedom relative to the carrier, and only three degrees of freedom relative to the base. The system also comprises an insertion tool coupled to the tool holder.

Yet another example of the present disclosure relates to a method of installing an electrical contact into a socket of a connector housing. The method comprises spatially fixing the connector housing relative to a base. Additionally, the method comprises coupling an insertion tool to the base with three degrees of freedom. The method also comprises partially installing the electrical contact into the socket of the connector housing or detachably coupling the electrical contact to the insertion tool. Further, the method comprises retracting the insertion tool away from the connector housing along an insertion axis of the socket. The method additionally comprises aligning the insertion tool with the socket of the connector housing. Also, the method comprises advancing the insertion tool into the socket of the connector housing along the insertion axis to bias the electrical contact into the socket with a force not exceeding a predetermined force.

Referring, e.g., to FIGS. 1-6, apparatus 100 for installing at least one electrical contact 152 into connector housing 150 is disclosed. Apparatus 100 comprises base 110 configured to fixedly support connector housing 150. Additionally, apparatus 100 comprises alignment guide 122 extending from base 110 and having central axis 164. With connector housing 150 fixedly supported by base 110, alignment guide 122 is configured to be parallel to insertion axis 160 of socket 154 of connector housing 150. Apparatus 100 also comprises carrier 124 translatably and pivotally coupled with alignment guide 122. With connector housing 150 fixedly supported by base 110, carrier 124 is movable parallel to insertion axis 160 of socket 154 of connector housing 150. Apparatus 100 further comprises tool holder 132 coupled to carrier 124. Tool holder 132 has working axis 162, only one degree of freedom relative to carrier 124, and only three degrees of freedom relative to base 110. The preceding subject matter of this paragraph characterizes example 1 of the present disclosure.

Apparatus 100 is configured to ensure at least one electrical contact 152 is predictably installed into socket 154 of connector housing 150 along insertion axis 160 of socket 154. Installing at least one electrical contact 152 into socket 154 of connector housing 150 along insertion axis 160 of socket 154 ensures at least one electrical contact 152 does not bind within socket 154. Tool holder 132 having only three degrees of freedom relative to base 110 promotes control and predictability of the position of insertion tool 140 relative to socket 154 of connector housing 150 when installing at least one electrical contact 152 into socket 154. Socket 154 of connector housing 150 is a connector cavity of connector housing 150 that receives at least one electrical contact 152, which can be an electrical pin or electrical socket.

Referring generally to FIG. 1 and particularly to, e.g., FIG. 4, tool holder 132 is coupled to carrier 124 such that minimum distance MD1 is defined between tool holder 132 and base 110. The preceding subject matter of this paragraph characterizes example 2 of the present disclosure, wherein example 2 also includes the subject matter according to example 1, above.

Coupling tool holder 132 to carrier 124 to defining minimum distance MD1 between tool holder 132 and base 110 ensures tool holder 132 is not movable closer to base 110 than minimum distance MD1. By ensuring tool holder 132 does not move closer to base 110 than minimum distance MD1, over-insertion of at least one electrical contact 152 into socket 154 of connector housing 150 is prevented. Additionally, defining minimum distance MD1 between tool holder 132 and base 110 helps to ensure at least one electrical contact 152 is not under-inserted into socket 154 of connector housing 150.

Referring generally to FIG. 1 and particularly to, e.g., FIGS. 2-6, carrier 124 comprises sleeve 180 and carrier arm 176 that is configured to be fixed to sleeve 180 and is rotatably coupled with tool holder 132. The preceding subject matter of this paragraph characterizes example 3 of the present disclosure, wherein example 3 also includes the subject matter according to example 2, above.

Rotation of tool holder 132 relative to sleeve 180 of carrier 124 enables adjustment of the position of tool holder 132 relative to sleeve 180 and alignment guide 122, thereby enabling adjustment of the position of tool holder 132 relative to connector housing 150.

Referring generally to FIG. 1 and particularly to, e.g., FIGS. 2-6, carrier arm 176 is configured to be releasably fixed to sleeve 180. Carrier arm 176 is selectively repositionable relative to sleeve 180 along central axis 164 to adjust minimum distance MD1 between tool holder 132 and base 110. Central axis 164 is configured to be parallel to insertion axis 160 of socket 154. The preceding subject matter of this paragraph characterizes example 4 of the present disclosure, wherein example 4 also includes the subject matter according to example 3, above.

Selectively repositioning carrier arm 176 relative to sleeve 180 to adjust minimum distance MD1 between tool holder 132 and base 110 accommodates the installation of electrical contacts 152 of various configurations into sockets 154 of connector housings 150 of various configurations.

As defined herein, movement of a first feature along a second feature means movement of the first feature parallel to or concentric with the second feature.

Still referring generally to FIG. 1 and particularly to, e.g., FIGS. 2-6, carrier arm 176 is configured to be releasably fixed to sleeve 180 of carrier 124 via attachment mechanism 182. The preceding subject matter of this paragraph characterizes example 5 of the present disclosure, wherein example 5 also includes the subject matter according to example 4, above.

Attachment mechanism 182 enables convenient repositioning of carrier arm 176 relative to sleeve 180.

Continuing to refer generally to FIG. 1, and particularly to, e.g., FIGS. 2-6, attachment mechanism 182 comprises clamp 183. The preceding subject matter of this paragraph characterizes example 6 of the present disclosure, wherein example 6 also includes the subject matter according to example 5, above.

Clamp 183 provides quick loosening and tightening of carrier arm 176 to sleeve 180 and secure releasable fixation of carrier arm 176 to sleeve 180.

Referring generally to FIG. 1, minimum distance MD1 is fixed. The preceding subject matter of this paragraph characterizes example 7 of the present disclosure, wherein example 7 also includes the subject matter according to any one of examples 2 or 3, above.

Fixing minimum distance MD1 enables predictable compatibility of carrier 124 with a given electrical contact 152 and a given connector housing 150. For example, one carrier 124 can be configured with one fixed minimum distance MD1 that is compatible with a one configuration of electrical contacts 152 and connector housing 150 and another carrier 124 can be configured with another fixed minimum distance MD1 that is compatible with another configuration of electrical contacts 152 and connector housing 150. Differently configured carriers 124 may be selectively coupled with alignment guide 122 according to which carrier 124 has minimum distance MD1 that is compatible with the configuration of electrical contacts 152 and connector housing 150.

Referring generally to FIG. 1 and particularly to, e.g., FIGS. 2-6, minimum distance MD1 is adjustable. The preceding subject matter of this paragraph characterizes example 8 of the present disclosure, wherein example 8 also includes the subject matter according to any one of examples 2-6, above.

Adjustability of minimum distance MD1 between tool holder 132 and base 110 accommodates the installation of electrical contacts 152 of various configurations into sockets 154 of connector housings 150 of various configurations.

Referring generally to FIG. 1 and particularly to, e.g., FIGS. 2-6, carrier 124 comprises end 170. Minimum distance MD1 between tool holder 132 and base 110 is equal to minimum distance MD2 between tool holder 132 and end 170 of carrier 124. End 170 of carrier 124 is configured to contact base 110. The preceding subject matter of this paragraph characterizes example 9 of the present disclosure, wherein example 9 also includes the subject matter according to any one of examples 2-8, above.

Because minimum distance MD1 between tool holder 132 and base 110 is equal to minimum distance MD2 between tool holder 132 and end 170 of carrier 124, contact between end 170 of carrier 124 and base 110 ensures tool holder 132 is minimum distance MD1 from base 110.

Referring generally to FIG. 1 and particularly to, e.g., FIGS. 2-6, tool holder 132 comprises coupler 172 configured to removably retain insertion tool 140 in tool holder 132. The preceding subject matter of this paragraph characterizes example 10 of the present disclosure, wherein example 10 also includes the subject matter according to any one of examples 1-9, above.

Coupler 172 facilitates ease in retaining insertion tool 140 in tool holder 132 and removing insertion tool 140 from tool holder 132. For example, one insertion tool 140 can be quickly removed from tool holder 132 and replaced with another insertion tool 140. Insertion tool 140 can include body 142, which houses constant force mechanism 146. Constant force mechanism 146 ensures a constant force is applied to electrical contact 152 as insertion tool 140 installs electrical contact 152 into socket 154 of connector housing 150. Additionally, constant force mechanism 146 can ensure force applied to electrical contact 152 from insertion tool 140 does not exceed a threshold force. In one example, insertion tool 140 is an RFX connector insertion tool manufactured by Russtech® of Irvine, Calif. Coupler 172 may also facilitate rotation of insertion tool 140 relative to tool holder 132 while removably retaining tool 140 in tool holder 132.

The preceding subject matter of this paragraph characterizes example 11 of the present disclosure, wherein example 11 also includes the subject matter according to example 10, above.

Removable retention of insertion tool 140 with a snap fit enables secure retention of insertion tool 140 while at least one electrical contact 152 is installed into connector housing 150. The snap fit may also provide audible or tactile feedback that insertion tool 140 is properly retained by tool holder 132. Further, in one example, coupler 172 is resiliently flexible to enable removable retention of insertion tool 140 by tool holder 132 with a snap fit.

Referring generally to FIG. 1 and particularly to, e.g., FIGS. 2-6, coupler 172 of tool holder 132 is configured to removably retain insertion tool 140 with an interference fit. The preceding subject matter of this paragraph characterizes example 12 of the present disclosure, wherein example 12 also includes the subject matter according to example 10, above.

Removable retention of insertion tool 140 with an interference fit enables secure retention of insertion tool 140 while at least one electrical contact 152 is installed into connector housing 150.

Referring generally to FIG. 1 and particularly to, e.g., FIGS. 2-6, coupler 172 of tool holder 132 is configured to interlock with insertion tool 140 to prevent insertion tool 140 from moving relative to coupler 172 along insertion axis 160 of socket 154. The preceding subject matter of this paragraph characterizes example 13 of the present disclosure, wherein example 13 also includes the subject matter according to example 10, above.

Interlocking of coupler 172 with insertion tool 140 enables secure retention of insertion tool 140 while at least one electrical contact 152 is installed into connector housing 150. In one example, coupler 172 includes a stop that engages body 142 of insertion tool 140 to prevent insertion tool 140 from moving relative to coupler 172 along insertion axis 160 of socket 154 toward base 110. Additionally, coupler 172 includes at least one tab that engages body 142 of insertion tool 140 to prevent insertion tool 140 from moving relative to coupler 172 along insertion axis 160 of socket 154 away from base 110. Engagement of both the stop and at least one tab of coupler 172 with body 142 of insertion tool 140 interlocks insertion tool 140 between the stop and at least one tab of coupler 172. The at least one tab of coupler 172 may be resiliently flexible to engage (e.g., interlock) and disengage (e.g., unlock) body 142 of insertion tool 140.

Referring generally to FIG. 1 and particularly to, e.g., FIGS. 3-6, central axis 164 of alignment guide 122 is configured to be parallel to insertion axis 160 of socket 154. Tool holder 132 is coupled to carrier 124 such that working axis 162 of tool holder 132 is parallel to central axis 164 of alignment guide 122. The preceding subject matter of this paragraph characterizes example 14 of the present disclosure, wherein example 14 also includes the subject matter according to any one of examples 1-13, above.

Coupling tool holder 132 to carrier 124 such that working axis 162 of tool holder 132 is parallel to central axis 164 of alignment guide 122 ensures working axis 162 of tool holder 132 is parallel to insertion axis 160 of socket 154. With working axis 162 of tool holder 132 parallel to insertion axis 160 of socket 154, and insertion tool 140 removably retained by tool holder 132, proper alignment of insertion tool 140 relative to insertion axis 160 of socket 154 is ensured for installing at least one electrical contact 152 into socket 154 of connector housing 150.

Referring generally to FIG. 1 and particularly to, e.g., FIGS. 3-6, minimum distance MD3 between central axis 164 of alignment guide 122 and working axis 162 of tool holder 132 is adjustable. The preceding subject matter of this paragraph characterizes example 15 of the present disclosure, wherein example 15 also includes the subject matter according to 14, above.

Adjustability of minimum distance MD3 between central axis 164 of alignment guide 122 and working axis 162 of tool holder 132 enables installation of at least one electrical contact 152 into any of various sockets 154 of connector housing 150. Connector housing 150 has multiple sockets 154 according to one example. With insertion tool 140 coupled to tool holder 132, minimum distance MD3 can be adjusted to align insertion tool 140 with any of multiple sockets 154 of connector housing 150. In some examples, after installing one electrical contact 152 into one socket 154 of connector housing 150, minimum distance MD3 is adjusted to install another electrical contact 152 into another socket 154 of connector housing.

Referring generally to FIG. 1 and particularly to, e.g., FIGS. 3-6, tool holder 132 comprises tool-holder arm 174 and carrier 124 comprises carrier arm 176 pivotally coupled with tool-holder arm 174. Minimum distance MD3 between central axis 164 of alignment guide 122 and working axis 162 of tool holder 132 is adjustable by pivoting tool-holder arm 174 relative to carrier arm 176. The preceding subject matter of this paragraph characterizes example 16 of the present disclosure, wherein example 16 also includes the subject matter according to example 15, above.

Pivoting tool-holder arm 174 relative to carrier arm 176 to adjust minimum distance MD3 between central axis 164 of alignment guide and working axis 162 of tool holder 132 facilitates ease in adjusting minimum distance MD3. Moreover, in one example, adjustment of minimum distance MD3 can be accomplished by pivoting tool-holder arm 174 relative to carrier arm 176 with carrier arm 176 fixed relative to alignment guide 122.

Referring generally to FIG. 1 and particularly to, e.g., FIGS. 3-6, minimum distance MD3 between central axis 164 of alignment guide 122 and working axis 162 of tool holder 132 is adjustable by pivoting carrier 124 relative to alignment guide 122. The preceding subject matter of this paragraph characterizes example 17 of the present disclosure, wherein example 17 also includes the subject matter according to example 16, above.

Pivoting carrier 124 relative to alignment guide 122 to adjust minimum distance MD3 between central axis 164 of alignment guide and working axis 162 of tool holder 132 facilitates ease in adjusting minimum distance MD3. Moreover, in one example, adjustment of minimum distance MD3 can be accomplished by pivoting carrier 124 relative to alignment guide 122 with tool-holder arm 174 fixed relative to carrier arm 176.

Referring generally to FIG. 1 and particularly to, e.g., FIGS. 2, 3, 5, and 6, alignment guide 122 comprises cylindrical rod 184. The preceding subject matter of this paragraph characterizes example 18 of the present disclosure, wherein example 18 also includes the subject matter according to any one of examples 1-17, above.

Cylindrical rod 184 of alignment guide 122 facilitates rotatability of carrier 124 relative to alignment guide.

Referring generally to FIG. 1 and particularly to, e.g., FIGS. 2-6, carrier 124 comprises sleeve 180 that is configured to receive cylindrical rod 184 of alignment guide 122. Additionally, sleeve 180 is configured to translate along cylindrical rod 184 in a direction parallel to insertion axis 160. Further, sleeve 180 is configured to rotate about cylindrical rod 184. The preceding subject matter of this paragraph characterizes example 19 of the present disclosure, wherein example 19 also includes the subject matter according to example 18, above.

Translation of sleeve 180 along cylindrical rod 184 in direction parallel to insertion axis 160 enables advancing of insertion tool 140 into socket 154 of connector housing 150 and withdrawal of insertion tool 140 from socket 154 of connector housing 150. The configuration of sleeve 180 and cylindrical rod 184 facilitates ease of translational motion between sleeve 180 and cylindrical rod 184. For example, sleeve 180 may include an internal channel with a diameter slightly larger than a diameter of cylindrical rod 184 such that a central axis of sleeve 180 may be slightly misaligned with central axis 164. Due to the larger diameter of the internal channel of sleeve 180 relative to the diameter of cylindrical rod 184, ease of translational motion between sleeve 180 and cylindrical rod 184 is promoted. Because of the length of sleeve 180 and cylindrical rod 184, slight misalignment between central axis of sleeve 180 and central axis 164 does not cause binding between sleeve 180 and cylindrical rod 184. Linear bearings may alternatively be used between sleeve 180 and cylindrical rod 184 to facilitate ease of translational motion between sleeve 180 and cylindrical rod 184. Rotation of sleeve 180 about cylindrical rod 184 facilitates adjustment of minimum distance MD3 and repositioning of insertion tool 140 relative to connector housing 150.

Referring generally to FIG. 1 and particularly to, e.g., FIGS. 2-6, alignment guide 122 is removably coupled to base 110.
