Description

TECHNICAL FIELD

This disclosure is directed to an electrical connector with an ergonomic axial mating assist device that provides for a reduced packaging size.

BACKGROUND

As vehicle electrical content increased, manufacturers desired to reduce the overall number of connection systems per vehicle, this led to a higher number of input/output (I/O) connections per system. Because these higher I/O connector systems have higher mating forces, hand-mating was undesirable. Instead, connector systems were often drawn together using bolts or special tools. Over time, bolted connections were replaced by an integral lever mating system for reducing mating forces to an ergonomically acceptable limit. These lever mating systems required pre-positioning the connector prior to closing the lever assist mechanism. Due to the cumbersome nature of this multi-step mating process, these connection systems were not ergonomically friendly and were also prone to improper mating and mating damage. Other ergonomic connector mating systems, such as those disclosed in U.S. Pat. Nos. 7,462,047, 7,744,390, 8,192,212, 9,912,101, 9,917,402, and 10,290,970 have used an axial slide and a gear rack to rotate a cam member to thereby draw two electrical connectors together. However, use of these ergonomic connector mating systems may be limited by the space required to provide the required travel of the axial slide to fully mate the connectors.

DETAILED DESCRIPTION

In contrast to prior ergonomic axial mating assist devices, the electrical connector presented herein does not use a gear rack to rotate the cam member as was done in those prior ergonomic axial mating assist devices. Instead, pin and channel features engage the axial slider with the rotating mate assist cam. The channel shape may be contoured to optimize the ergonomic force feedback to the assembly operator mating the connector. This arrangement reduces the forward slider travel, compared to previous gear rack driven connector systems and enables the use of more compact short length device headers, which are desirable for space savings, especially in automotive vehicle packaging. This connector presented herein also includes several other features that provide low part cost and low cost assembly methods.

A non-limiting example of a connector system 100, in this example an electrical connector system, is shown in FIG. 1. The connector system 100 includes a first connector 102 and a corresponding mating second connector 104. The first connector 102 includes a connector housing 106 and a cam member 108 which is rotatably attached to the connector housing 106 by a pivot 110. The first connector 102 also includes a user moveable member, hereafter referred to as the slide 112, which is slidably attached to the connector housing 106 and is sized and shaped to be mounted over the connector housing 106 and to surround the connector housing 106. Movement of the slide 112 along a longitudinal axis X (shown in FIG. 2) of the connector housing 106 causes the cam member 108 to rotate around the pivot 110 which assists in mating and unmating the first and second connectors 102, 104 as will be explained in detail below. The first connector 102 further includes a connector position assurance (CPA) device 114 that is configured to retain the first connector 102 to the second connector 104 once they are fully mated. The first connector 102 also includes a cable strain relief device 116 which is configured to snap over wire electrical cables 202 (see FIG. 2) that are attached to electrical terminals (not shown) within the connector housing 106 and a secondary terminal locking feature 118 which inhibits primary terminal locking features 904 (see FIGS. 9 and 10) from inadvertently releasing electrical terminals attached to the wire electrical cables 202.

As illustrated in FIG. 2, the cam member 108 has an engaging lug 204 in the form of a post that extends along a vertical axis Z that is substantially parallel to an axis of rotation R of the cam member 108 around the pivot 110. The slide 112 defines a curved first cam slot 206 in which the engaging lug 204 defined by the cam member 108 is received. The first cam slot 206 has a substantially straight entrance portion 208 that is generally parallel to the longitudinal axis X, a curved camming portion 210, and a substantially straight end portion 212 that is generally perpendicular to the longitudinal axis X. Additionally, the connector housing 106 defines rails 214 that are received within slots 216 in the slide 112. The rails 214 and the slots 216 are configured to cooperate with one another to cause the slide 112 to move relative to the connector housing in a substantially straight path along the X axis.

FIGS. 3 and 4 show the movement of the engaging lug 204 within the first cam slot 206 as the slide 112 moves relative to the connector housing 106. The cam member 108 is rotated by movement of the engaging lug 204 through the first cam slot 206 as the slide 112 is moved longitudinally relative to the connector housing 106.

FIGS. 5 and 6 show top and isometric views respectively of the connector housing 106 and the cam member 108 on the pivot 110 with the engaging lug 204 in a position to be received within the first cam slot 206.

As shown in FIGS. 7 and 8, the slide 112 is attached to the connector housing 106 and the engaging lug 204 is aligned with and inserted into the entrance portion 208 of the first cam slot 206. In some embodiments, the slide 112 defines a strap 702 bridging the entrance portion 208 of the first cam slot 206. The strap 702 generally increases the rigidity off the slide 112.

FIGS. 9 and 10 show front and rear views respectively of the connector 102. Terminal cavities 902 are defined by the connector housing 106 and hold the electrical terminals are shown in FIGS. 9 and 10. The second connector 104 further includes mating electrical terminals (not shown). The terminal cavities 902 define primary terminal locking features 904 that are configured to retain the electrical terminals in the terminal cavities 902. The secondary terminal locking feature 118 is configured to inhibit flexing of the primary terminal locking features 904 that could cause them to inadvertently release the electrical terminals.

FIG. 11 shows a locking barb 1102 in the slide 112 that is configured to engage a catch 1002 on the connector housing 106 previously shown in FIG. 10. The catch 1002 is configured to engage the barb 1102 in order to retain the slide 112 to the connector housing 106.

As shown in FIG. 12, the second connector 104 defines a camming post 1202.

The camming post 1202 is received within a second cam slot 1302 in the underside of the cam member 108 shown in FIG. 13. The second cam slot 1302 has a substantially straight entrance portion 1304 and a curved camming portion 1306. As the cam member 108 is rotated by moving the slide 112 forward on the connector housing 106, the camming post moves along the curved camming portion 1306 second cam slot 1302, thereby mating the first and second connector 102, 104 together. Once mated, the first and second connector 102, 104 may be unmated by rotating the cam member 108 in the opposite direction by moving the slide 112 rearward on the connector housing 106.

FIGS. 14 through 17 show a sequence of mating the first connector 102 with the second connector 104.

In FIG. 14, the first and second connectors 102, 104 are in a pre-mated condition. The engaging lug 204 of the cam member 108 is disposed within the entrance portion 208 of the first cam slot 206 in the slide 112. The second connector 104 is spaced apart from the first connector 102 and the camming post 1202 of the second connector 104 is aligned with the entrance portion 1304 of the second cam slot 1302 in the cam member 108.

In FIG. 15, the first and second connectors 102, 104 are in a pre-staged condition in which the slide 112 is at the beginning of its travel path and the engaging lug 204 of the cam member 108 remains within the entrance portion 208 of the first cam slot 206. The camming post 1202 is inserted within the entrance portion 1304 of the second cam slot 1302.

In FIG. 16, the first and second connectors 102, 104 are drawn together as the movement of the slide 112 along the X axis causes the engaging lug 204 to move through the entrance portion 208, into the curved camming portion 210, and toward the end portion 212 of the first cam slot 206. The movement of the slide 112 along the X axis also causes the camming post 1202 to move through the entrance portion 1304 and into the curved camming portion 1306 of the second cam slot 1302 on the other side of the cam member 108. The shape of the curved camming portion 210 of the first cam slot 206 causes the cam member 108 to rotate around the pivot 110 as shown in FIG. 16, thereby further causing the camming post 1202 to move through the curved camming portion 1306 and toward the end of the second cam slot.

In FIG. 17, the first and second connectors 102, 104 are in a staged condition in which they are fully mated. The slide 112 is at the end of its travel path and the engaging lug of the cam member 108 is disposed in the end portion 212 of the first cam slot 206. The camming post 1202 of the second connector 104 is also disposed within the end of the second cam slot 1302 in the cam member 108.

The first and second connectors 102, 104 may be separated and discommended by moving the slide 112 in the opposite direction shown in FIG. 16.

FIGS. 18 through 21 show a sequence of attaching the cable strain relief device 116 over the wire electrical cables 202. In FIG. 18, the latches 1802 of the cable strain relief device 116 are detached, and the cable strain relief device 116 is opened so that it may be placed over the wire electrical cables 202. In FIG. 19, the cable strain relief device 116 is placed over the wire electrical cables 202. In FIG. 20, the cable strain relief device 116 is closed, and the latches 1802 of the cable strain relief device 116 are engaged to secure it to the wire electrical cables 202. In FIG. 21, the cable strain relief device 116 slides along the wire electrical cables 202 and is disposed within a cavity 2002 (see FIG. 20) in the connector housing 106.
