This disclosure relates to the field of connectors, more specifically to high power connectors.
High power connectors are typically used in connections between electrical components. A circular female socket receives a male pin for making the electrical connection. The male pin is generally crimped to a wire. A single pair of connectors, a supply connector and a return connector, are typically used. In some instances, ganged or multiple pin/socket pairs are used that provide more power.
According to an embodiment of the disclosure, a connector is configured to be mounted to first and second electrical components. The connector includes an insulative housing having latches which can be pressed into a pressed condition, and a conductive body and a lock mounted within the housing. The body has engagements configured to be coupled to the electrical components. The lock is in contact with the latches and is movable therewith when the latches are pressed. The lock engages with a coupling pin of one of the electrical components to secure the electrical component to the connector.
To better understand the above-described objectives, characteristics and advantages of the present disclosure, embodiments, with reference to the drawings, are provided for detailed explanations.
The present disclosure is illustrated by way of example and not limited in the accompanying figures in which like reference numerals indicate similar elements and in which:
While the disclosure may be susceptible to embodiment in different forms, there is shown in the drawings, and herein will be described in detail, a specific embodiment with the understanding that the present disclosure is to be considered an exemplification of the principles of the disclosure, and is not intended to limit the disclosure to that as illustrated and described herein. Therefore, unless otherwise noted, features disclosed herein may be combined to form additional combinations that were not otherwise shown for purposes of brevity. It will be further appreciated that in some embodiments, one or more elements illustrated by way of example in a drawing(s) may be eliminated and/or substituted with alternative elements within the scope of the disclosure.

In the embodiment as shown which is adapted for forming a right-angle connector, the barrel 92 has opposing front and rear wall surfaces 98, 100 which are coupled together by opposing top and bottom wall surfaces 102, 104 and opposing side wall surfaces 106, 108. A wall 110 forming a passageway 112 extends from the bottom wall surface 104, and may be open to the top wall surface 102. The passageway 112 has an upper portion 114 which extends from the top wall surface 102 to a lower portion 116 which extends to the bottom wall surface 104. The upper portion 114 has a diameter that is larger than the diameter of the lower portion 116 such that an upper wall 118 is defined by the upper portion 114. A centerline CL of the passageway 112 is provided between ends thereof. In an embodiment, the barrel 92 is a cylinder truncated on its upper and lower ends.
In an embodiment and as shown, the first engagement 94 includes a contact 120 which is separately formed from the barrel 92 and secured to the barrel 92 by a cap 122. The contact 120 has a generally hollow shape which generally conforms to the shape of the inner surface of the wall 110 forming the passageway 112 in the barrel 92. The contact 120 may be formed of an alloy with gold plating. In an embodiment, the contact 120 is formed from a ring-like connecting portion 124 having a plurality of separate flexible beams 126 cantilevered therefrom such that a passageway 128 is formed therein which extends from an upper end of the contact 120 to a bottom end of the contact 120. A centerline of the contact 120 is provided between the ends. In an embodiment, the connecting portion 124 is discontinuous around its circumference such that a slot is provided. The connecting portion 124 has a plurality of spaced apart inwardly extending protrusions 130 and outwardly extending protrusions 130 provided thereon which may be aligned around the circumference of the connecting portion 124. The inwardly and outwardly extending protrusions 130 may alternate between a protrusion extending outwardly from the outer surface of the connecting portion 124 and a protrusion extending inwardly from the inner surface of the connecting portion 124. The beams 126 extend from the lower end of the connecting portion 124. Each beam 126 is parallel to, and radially spaced from, the centerline of the contact 120. The beams 126 are spaced apart from each other around the circumference of the connecting portion 124. In an embodiment, each beam 126 has a first portion 132 which extends at an angle from the connecting portion 124 at a corner, and a second portion 134 which extends at an angle from an end of the first portion 132 at a corner. The first portion 132 angles inwardly toward the centerline of the contact 120, and the second portion 134 angles outwardly from the centerline of the contact 120. The corners between the first and second portions 132, 134 may be radiused. In an embodiment, the corners between the first and second portions 132, 134 are aligned around the circumference of the contact 120 and define an inner diameter. The inner diameter defined by the corners between the first and second portions 132, 134 is less than the diameter of the cylindrical portion 36 of the coupling pin 26. The contact 120 may be stamped out of a flat sheet of material and rolled into the shape. The contact 120 may be machined into the shape.
In an embodiment, the cap 122 has an annular lower wall 136 which defines a central passageway 138, and an upper wall 140 extending radially outwardly from and perpendicular to the lower wall 136.
The contact 120 is seated within the lower portion 116 of the passageway 112 in the barrel 92 such that the upper and lower ends of the contact 120 do not protrude from the upper and lower ends of the barrel 92. The centerline CL of the passageway 112 and the centerline of the contact 120 align. The ends of the second portion 134 of the beams 126 are spaced from the wall surface forming the lower portion 116 of the passageway 112. The outer surface of the connecting portion 124 is proximate to the inner surface of the wall 110 forming the lower portion 116 and the outwardly extending protrusions 130 abut against the inner surface of the wall 110 forming the lower portion 116. The cap 122 secures the barrel 92 and the contact 120 together. In an embodiment, the cap 122 is press fit to the barrel 92 and to the contact 120. In an embodiment, the cap 122 is crimped to the barrel 92 and to the contact 120. The wall 136 of the cap 122 engages against the inwardly extending protrusions 130 of the contact 120 and has a diameter which is greater than a diameter defined by the inwardly extending protrusions 130. When the wall 136 of the cap 122 is engaged with the connecting portion 124, the protrusions 130 are deformed to secure the contact 120 to the barrel 92. The upper wall 140 is seated within the upper portion 114 of the passageway 112 in the barrel 92 and engages the upper wall 118.
Other first engagements are within the scope of the present disclosure.
The second engagement 96 may be formed as a crimp body that is crimped to wires of a cable (not shown) coupled to the second electrical component 24, may be soldered, welded, screw attached and the like. In some embodiments, the second engagement 96 has a plurality of flexible beams like that provided for the first engagement 94 which mate with a pin extending from the second electrical component 24. In some embodiments, the second engagement 96 is a pin that is inserted into a plated via or surface mounted to a contact pad of the second electrical component 24.

When the latch 74 is pressed inwardly into the passageway 68, the third lock wall 160 and the first lock wall 146 are moved toward the side wall 66. The engagement of the first arm portion 150 with the rear wall 58 constrains the movement the third lock wall 160 and the first lock wall 146 so that the third lock wall 160 and the first lock wall 146 only move toward the side wall 66. Likewise, when the latch 76 is pressed is pressed inwardly into the passageway 68, the fourth lock wall 162 and the second lock wall 148 are moved toward the side wall 64. The engagement of the first arm portion 154 with the front wall 56 constrains the movement the fourth lock wall 162 and the second lock wall 148 so that the fourth lock wall 162 and the second lock wall 148 only move toward the side wall 64. The length L2 of the receiving opening 158 does not change. Therefore, when both latches 74, 76 are pressed, the second arm portions 152, 156 move away from each other, thereby increasing the width W2 of the receiving opening 158. In some embodiments, a gap may be provided between the first arm portion 150 and the rear wall 58 and/or the first arm portion 154 and the front wall 56 to allow some movement of the first arm portions 150, 154 under this movement.
The coupling pin 26 can be quickly and easily attached to the connector 20 and released from the connector 20 without the use of tools. To couple the coupling pin 26 to the connector 20, the first end 36a of the cylindrical portion 36 of the coupling pin 26 is inserted through the opening 90 and then through the first opening 70 of the housing 28, through the receiving opening 158 of the lock 32, and into the contact 120. The cylindrical portion 36 has a diameter which is greater than the width W2 of the receiving opening 158 when the latches 74, 76 are not in the pressed condition and slightly less than the length L2 of the of the receiving opening 158 when the latches 74, 76 are not in the pressed condition. When the first end 36a contacts the second arm portions 152, 156 of the first and second lock walls 146, 148, the second arm portions 152, 156 move away from each other, thereby increasing the width W2 of the receiving opening 158. The rounded or spherical shape of the first end 36a provides a lead-in for the coupling pin 26. This will cause the latches 74, 76 to move slightly outward from the side walls 64, 66. The cylindrical portion 36 engages with the beams 126, which causes the beams 126 to flex outward from the centerline CL of the passageway 112. This ensures an electrical connection between the coupling pin 26 and the contact 120. The coupling pin 26 is inserted into the housing 28 until the flange 38 seats within the opening 90. At this position, the groove 40 aligns with the second arm portions 152, 156, and the latches 74, 76 resume their unpressed condition which causes the second arm portions 152, 156 to move toward each other to decrease the width W2 of the receiving opening 158 and seat within the groove 40. This prevents the coupling pin 26 from being readily pulled out from the connector 20. The bridge 80 controls the lift of the first and second lock walls 146, 148, and improves the retention force of the latches 74, 76 while maintaining the low profile of the connector 20. The dimension of the space 88 controls the deflection of the latches 74, 76.
The coupling pin 26 can be quickly and easily released from the connector 20 by the operator pressing the latches 74, 76 into the passageway 68. When the latches 74, 76 are pressed inwardly into the passageway 68, the third lock wall 160 and the first lock wall 146 are moved toward the side wall 66, and the fourth lock wall 162 and the second lock wall 148 are moved toward the side wall 64, thereby increasing the width W2 of the receiving opening 158. This moves the second arm portions 152, 156 out of the groove 40. The operator can then easily pull the coupling pin 26 out of the connector 20.
In an alternate embodiment, the fifth lock wall 164 of the lock 32 is not provided and the rear ends of the third and fourth lock walls 160, 162 are secured to the latches 74, 76 of the housing 28. In yet another alternate embodiment, the third, fourth and fifth lock walls 160, 162, 164 of the lock 32 are eliminated and the first lock wall 146 is affixed to the first latch 74 and the second lock wall 148 is affixed to the second latch 76. The receiving opening 158 aligns with and is proximate to the first opening 70.
In some embodiments, the wall which is proximate to the first end 36a of the coupling pin 26 when the coupling pin 26 is seated in the connector 20 has an opening (not shown) therethrough.
