Hospital bed equipment support apparatus
First Claim
1. An electrical connector, including:
- a receptacle having a first end, a second end, a cavity extending toward the second end from an opening at the first end, a first detent extending into the cavity at a first distance from the opening, and a second detent extending into the cavity at a second distance from the opening, the second distance being greater than the first distance; and
a plug being removably received by the receptacle cavity, the plug having a body and a stop for limiting the extent to which the body may be inserted into the cavity, thereby defining a seated position, the body including first and second contacts that contact the first and second receptacle detents, respectively, in the seated position, wherein the second contact contacts the first detent during insertion of the plug into the receptacle cavity.

Abstract
An equipment support for use with a patient assist apparatus having a signal source includes a receptacle adapted to mount to the patient assist apparatus having a plurality of contacts adapted to receive signals from the signal source and a cavity, and a support body or pole having an equipment mount on one end and a plug on the other end for being removably inserted into the cavity. The plug includes a plurality of contacts that are connected to conductors that extend through the support body to the equipment mount to provide the signals from the signal source to equipment mounted on the equipment mount. The plug contacts and receptacle contacts are arranged such that all of the plug contacts contact their corresponding receptacle contacts as the plug is inserted into the receptacle.

11. An electrical connector, including:
-
a receptacle having a first end, a second end, a cavity including a central axis and extending toward the second end from an opening at the first end, a first contact extending into the cavity at a first distance from the opening, and a second contact extending into the cavity at a second distance from the opening, the second distance being greater than the first distance; and a plug being removably received by the receptacle cavity, the plug having a body and a stop for limiting the extent to which the body may be inserted into the cavity, thereby defining a seated position, the body including first and second contacts that contact the first and second receptacle contacts, respectively, as the body approaches the seated position, the body being substantially cylindrical, and each of the plug contacts including a ring portion having a diameter that is greater than a diameter of the body, the ring portions being offset from the receptacle contacts along the central axis to resist removal of the plug from the receptacle when the plug body is in the seated position. - View Dependent Claims (12, 13, 14)

15. An electrical connector, including:
-
a receptacle having a first end, a second end, a cavity extending toward the second end from an opening at the first end, a first contact extending into the cavity at a first distance from the opening, a second contact extending into the cavity at a second distance from the opening, the second distance being greater than the first distance, a third contact extending into the cavity at a third distance from the opening, the third distance being greater than the second distance; and a plug being removably received by the receptacle cavity, the plug having a body and a stop for limiting the extent to which the body may be inserted into the cavity, thereby defining a seated position, the body including first, second, and third, contacts that contact the first, second, and third, receptacle contacts, respectively, as the body approaches the seated position, the plug body being cylindrical and the plug contacts being annular, the plug further including a first annular insulator disposed between the first and second plug contacts, and a second annular insulator disposed between the second and third plug contacts, the first and second annular insulators having a different length, such that one plug contact contacts one receptable contact during insertion and prior to being seated. - View Dependent Claims (16)

17. An electrical connector, including:
-
a receptacle having a first end, a second end, a cavity extending toward the second end from an opening at the first end, a first contact extending into the cavity at a first distance from the opening, a second contact extending into the cavity at a second distance from the opening, the second distance being greater than the first distance, a third contact extending into the cavity at a third distance from the opening, and a fourth contact extending into the cavity at a fourth distance from the opening, the third distance being greater than the second distance and the fourth distance being greater than the third distance; and a plug being removably received by the receptacle cavity, the plug having a body and a stop for limiting the extent to which the body may be inserted into the cavity, thereby defining a seated position, the body including first, second, third, and fourth contacts that contact the first, second, third, and fourth receptacle contacts, respectively, as the body approaches the seated position, the distance between the first and second plug contacts is different from the distance between the second and third plug contacts, such that one plug contact contacts one receptacle contact during insertion and prior to being seated. - View Dependent Claims (18)

19. An electrical connector, including:
-
a receptacle having a cavity including a central axis and a first conductor adjacent the cavity; and a plug having a second conductor adjacent an outer surface of the plug, and an annular ring that has an increased diameter relative to another diameter of the plug; wherein a signal on the first conductor is coupled to the second conductor when the plug is substantially fully inserted into the receptacle cavity, the receptacle including a detent being offset with respect to the ring to resist removal of the plug from the receptacle when the plug is substantially fully inserted into the cavity. - View Dependent Claims (20, 21)
