Description

Connector guides and connectors with latches {CONNECTOR GUIDE WITH LATCH AND CONNECTORS THEREFOR}

The present invention relates generally to cable connectors, and more particularly to cable connectors having a structure that eliminates the need for a shielding cage or guide frame used with a mating circuit board connector.

It is common practice in the field of electronics to connect cables to circuit boards by terminating the cable with a connector, usually a plug connector, and then matching the connector to a receptacle connector mounted on the circuit board. A known problem in connecting cables to circuit board mounted connectors is that the weight and movement of the cable loosen the point of attachment of the receptacle connector to the circuit board, blocking the signal path and damaging the circuit board.

This problem can be avoided by using a large guide frame that is mounted on the circuit board to surround the receptacle connector and forms an opening into which a plug or similar connector can be inserted. However, these guide frames are large and occupy useful space on the circuit board that can be used for additional circuitry or terminations. In addition, such guide frames are typically easily broken when die cast and dropped.

Connector receptacle strain is also a problem, which can be caused by the weight size and movement of the cable. In addition, the connector plug and its mating connector receptacle can often be misaligned with each other, which unnecessarily complicates the assembly process. There is also a need for a device that aligns plug connectors to mating connector receptacles without taking up a lot of space and alleviates cable strain imposed on circuit board-mounted connectors.

In addition, the use of large connector guide frames increases the space on the circuit board that may be used for other electronic components. Moreover, the guide frames are designed to collectively surround and receive the connectors they host.

The present invention therefore relates to an apparatus using a guide member which overcomes the above mentioned disadvantages and also provides the above-mentioned certain benefits.

It is therefore a general object of the present invention to provide a guide assembly for a surface mount connector that guides a plug connector to an opposing receptacle connector and at least partially maintains the plug connector in contact with the opposing receptacle connector.

Another object of the present invention is to provide an alignment guide member for guiding a connector plug to mate with a surface receptacle-mounted connector and maintaining alignment between the plug connector and the receptacle connector.

Another object of the present invention is to provide a receptacle connector for electrically coupling an electrical path on a circuit board to an electrical contact where a plug connector can be mated, and to align and guide the plug connector to mate with the receptacle connector and provide strain relief to the receptacle connector. It is to provide an electrical connector assembly for mounting on a circuit board or other substrate having a guide capable of doing so.

It is yet another object of the present invention to provide a guide member for a surface mount receptacle connector that does not require the use of a guide frame with a receptacle connector, wherein the guide member is formed of a conductive material and provided to the circuit board near the mating end of the receptacle connector. A hollow passageway that can be attached, wherein the guide member comprises means for providing a friction fit with the plug connector, the guide member guiding to form a contact point between the plug connector and the guide member inserted into the guide member. And a retention tab extending from the member toward the receptacle member.

It is yet another object of the present invention to provide a plug connector for use with the receptacle connector and guide member described above, wherein the plug connector includes a mating surface having a front protruding mating blade that fits in a corresponding slot in the receptacle connector; And the plug connector further comprises a protruding tab extending forwardly over the plug connector mating surface, the tab having a recess therein for receiving corresponding tabs of the guide member, wherein the plug connector tab is receptacle connector when mated. Extends over the housing.

Another object of the present invention is to provide a surface mount and vertically oriented edge receptacle connector, wherein the guide member comprises a guide formed of a conductive material such as sheet metal forming an open channel oriented towards the mating surface of the receptacle connector. In addition, the guide member includes an engaging portion for engaging the opposite portion of the plug connector.

The present invention achieves the above object and other objects and aspects by a structure including a guide for guiding a connector plug to a circuit board-mounted connector as one important aspect. In a preferred embodiment, the connector guide is a U-shaped guide member that is reversed when mounted to a circuit board or similar substrate and positioned forwardly away from the receptacle connector. The plug connector is inserted into the guide member and guides the plug portion of the plug connector to align with the receptacle connector.

In a preferred embodiment, the U-shaped guide member has two opposing flat side plates extending perpendicular to the flat top plate. The side plate may include one or more tabs stamped from the guide member and protruding inward to frictionally contact the plug connector housing when the plug connector is inserted into the guide member. The distance that these tabs extend into the interior of the guide member may act as an alignment function by directing the plug connector towards the center of the guide member. When the plug connector is inserted into the guide member and the receptacle connector, the tabs contact the sides of the plug connector to slow down the insertion operation.

The guide member also includes an extension in the form of a spring arm that extends well from the top plate. The spring arm may extend between the guide and the receptacle connector or may extend slightly above the top of the receptacle connector. The free end of the spring arm is formed to form a detent on top that engages a slot or channel formed on top of the plug connector to provide tactile means for directing that the plug connector is properly inserted and mated with the receptacle connector. Can be.

In another embodiment, the guide member uses a vertical orientation coupled with the vertical receptacle connector. Also, this embodiment generally takes a U-shape, and the top plate (extending vertically along one of the sides of the receptacle connector) may have a spring arm stamped from the top plate and present within the boundaries of the top plate. In another vertical embodiment, the guide forms a hollow passageway extending over the receptacle connector mating area and into which the plug connector is inserted.

These and other objects, features and advantages of the present invention will be more clearly understood in view of the following detailed description.

FIG. 1 shows an exploded view of an electrical assembly 2 used to exchange electrical signals between a conductive trace 6 of a circuit board or other substrate 4 and an electrical conductor in the cable 101. The electrical assembly 2 shown in FIG. 1 includes a circuit board 4 on which electronic components such as integrated circuits, resistors, capacitors, inductors and the like can be mounted. As is known, the electronic components mounted on the circuit board are interconnected by one or more conductive traces 6 and at least some are located on at least the surface of the substrate 4. The electrical signal can be transmitted through the conductive trace 6 by a receptacle connector 8 mounted to the substrate 4 and mating with the opposing cable connector.

1 shows a receptacle connector 8 attached to a circuit board 4 using any of the mounting posts, screws or solders known in the art. The receptacle connector 8 has two opposing sides 10, 12, an upper part 14, a lower part 15, a front part 16 and a rear part 18. The receptacle connector 8 is constructed and arranged to maintain a space of a number of front accessible electrical connectors, each of which is electrically coupled to a corresponding conductive trace 6 on the circuit board 4.

Electrical and mechanical connection to the contact 20 accessible at the front 16 side of the receptacle connector 8 is achieved by extending the plug-shaped mating connector 100 to contact the receptacle connector 8. The plug connector 100 has its own set of conductive contacts that mate with the receptacle connector contacts 20, wherein the plug connector is a guide member or shell mounted to the circuit board in a position spaced forward from the receptacle connector 8. Guided by at least partly in place (24). In the preferred embodiment, the guide member 24 is generally U-shaped and formed as a hood or shield, which is reversed when installed on the circuit board 4. The guide member 24 forms a hollow channel 80 between the circuit board 4 and which the plug connector 100 can extend to engage the mating receptacle connector 8.

As shown in Fig. 1, the connector guide member 24 preferably includes at least two flat sides 26, 28. The flat side 26 has an upper edge 30 and a lower edge 32 and the second side 28 also has an upper edge 34 and a lower edge 36. Each flat side 26, 28 further comprises a front edge and a rear edge. The first side 26 has a front edge 38 and a rear edge 42. The second side 28 has a front edge 40 and a rear edge 44. Preferably, two mounting posts 70 (FIG. 4) are formed in the guide member along the bottom of the side, the posts can be circular and stamped as part of the guide member itself. Regardless of its structure, the post 70 extends downward from the sides 26, 28 and is received in a mounting hole 25 formed in the circuit board 4. The post can be used to solder the guide member in place on the circuit board 4 and to connect the guide member to a ground circuit on the circuit board 4.

As shown in Figure 7, the opposing first and second sides 26, 28 of the guiding member are substantially the same height 46 between the upper and lower edges, and approximately the same between the front and rear edges of each side. It is desirable to have a width 48. As shown in FIG. 1, the sides 26, 28 are generally upright and extend generally at right angles to the flat top 52. 1-9 show a horizontal embodiment of a guide member 24 stamped from a single piece of sheet metal for purposes of disclosure, however, the top 52 and the two sides 26, 28 may be joined together at a common edge. . Top 52 has a first side edge 54 shown on the right and a second side edge 56 shown on the left as seen from the front as in FIG. The top 52 also has a front edge 58 and a back edge 60.

Importantly, the guide member 24 may be stamped from a relatively hard metal in a pattern in which an extension of the guide member taking the form of a tab or spring arm 64 extending rearward is formed. In the figure, the spring arm is shown as a cantilever-shaped extension and is preferably formed at a slightly downward angle θ which creates a bias or preload in the spring arm 64 as shown in FIG. The bias forces the plug engagement shown by the ridge or catch 62 located near the distal end of the spring arm 64 to engage the corresponding slot or recess 102 formed in the corresponding portion of the plug connector. This structure can be used to properly position the plug connector in place within the guide member 24 and to ensure engagement with the receptacle connector. This structure can also apply some downward force onto the upper flange of the plug connector.

2 is a rear perspective view of the connector receptacle 8 and the relative position of the guide member 24 with respect to the connector plug 8.

Small tabs that engage with the iron 57 are formed to form on the sides. Those skilled in the art will appreciate that when the connector plug 100 is fully engaged with the complementary connector receptacle, the side locking latch 55 (substantially on both sides 26 and 28 of the guide member 24) stops correspondingly. It will be appreciated that the engagement with the iron 57 and "latch" the connector plug 100 to the connector receptacle 8. The latching is achieved by the guide member 24, not by the connector receptacle 8, which means that the cable strain is absorbed by the guide member 24 and not the connector receptacle 8. In addition, any misalignment of the conductors in the plug 100 and the receptacle 8 is minimized by the plug-to-receptacle alignment performed by the inner member 24. Both side latches 55 and the upper press arm form a three-way means of engagement with the plug connector 100.

This figure shows a generally rectangular sidewall with a height 46 which is the distance between the lower edge 36 and the upper edge 32 of the side 28 shown. Similarly, this figure shows a width 46 which is the distance between the front and rear edges 40, 44. In addition, the mounting post 70 is shown as an upper portion 52 of the guide member 24. FIG. 7 also shows the angle θ (acute angle) oriented downward between the plane of the upper surface 52 and the press or spring arm 64. The spring arm 64 is biased downwards as shown to ensure that the catch 62 contacts and engages the plug connector slot 102 so that the plug connector 100 remains engaged with the mating receptacle connector.

8 shows a top view of the guide member 24. In particular, this figure shows the structure of the side lock latch 52 stamped into both sides 26, 28 of the guide member 24. This figure also shows two cutouts 57, 59 on both sides of the spring arm 64 providing additional flexibility to the spring arm 64. Finally, FIG. 9 shows a rear view of the guide member 24. In this figure, the extension of the locking latch 55 is clearly shown to extend into the U-shaped channel 80 lying in the two opposing sides 26, 28 and generally below the flat top 52. This figure also shows an attachment post 70 extending away from the lower edges 32, 36 of the sides 26, 28, respectively.

From the above, when the U-shaped guide member 24 is attached to the circuit board 4, even if the guide member 24 is electrically and mechanically disconnected and not connected to the connector receptacle 8, the guide member is connected to the plug connector. Those skilled in the art will understand that they can be enclosed and lock the plug connector in place to absorb cable strain and provide electrical contact alignment. The catch 62 and the side engagement tab 55 in another embodiment hold the plug connector in place within the guide member 24.
