The present disclosure provides a coupling system for coupling a medical accessory to an accessory support is provided. The present disclosure also provides a system for powering a medical accessory with an accessory support.

The present application relates to a terminal retainer, a connector housing, connector, and connector assembly. The terminal retainer has a tubular retaining part and the tubular retaining part comprises a tube wall and a cavity enclosed by the tube wall; the tubular retaining part axially extends a specified length; the tube wall is provided with a locking mechanism and the locking mechanism comprises an initial locking mechanism and a final locking mechanism which are respectively fitted with a mating mechanism to lock the terminal retainer in an initial locking position and a final locking position, respectively; the tube wall is further provided with an abutment mechanism, and the abutment mechanism is configured to abut against a snap-fit mechanism located in the cavity when the terminal retainer is in the final locking position so that the snap-fit mechanism can be retained in a snap-fit position. The terminal retainer may be preassembled with a connector housing to avoid scattering and loss of parts and to be ready for use.

An electrical connector is used to be electrically connected to a mating component. The electrical connector includes a body having an insertion slot for the mating component to insert therein along a mating direction, and two side walls located at two opposite sides of the insertion slot and extending along an elongated direction perpendicular to the mating direction. A retainer is provided at one end of the body along the elongated direction to buckle with the mating component. Multiple terminals are provided on the two side walls, protruding into the insertion slot to mate with the mating component. A metal member is provided on the body and correspondingly covering one of the side walls. The metal member is provided with at least one through slot provided obliquely relative to the mating direction and adjacent to the retainer in the elongated direction.

A terminal, wherein, the lower and upper arms have a plurality of integral lower flexible arms and integral upper flexible arms respectively, which include at least a first lower and upper flexible arm and a second lower and upper flexible arm that are elastically displaceable independently of each other, the lower striking portions each have a first and second lower striking portion formed on a first and second lower flexible arm respectively, the second lower striking portion at a position that is offset in the longitudinal direction with respect to the first lower striking portion, and the upper striking portions each have a first and second upper striking portion formed on a first and second upper flexible arm respectively, the second upper striking portion at a position that is offset in the longitudinal direction with respect to the first upper striking portion.

Plug side housings can be joined to each other by dovetail jointing without requiring experience and in an efficient manner. One of the opposing faces of adjacent plug side housings is provided with a groove and a positioning groove extending from at least one end of the groove in a same direction as the groove and configured to loosely receive a linear protrusion provided on the other opposing face, or the other opposing face is provided with a positioning protrusion extending from at least one end of the linear protrusion in a same direction as the linear protrusion and configured to be loosely fitted in the groove provided on the one opposing face.

Connector apparatus having a female connector assembly and a male connector assembly. The female connector assembly includes a female housing, a connector position assurance (CPA) member for assuring the engagement of the male connector assembly with the female connector assembly, and a first terminal position assurance (TPA) member for assuring that terminals for the female connector assembly are positioned properly. The female housing further includes a connector latch used to securely hold together a connector apparatus. The female housing has TPA protection ribs and CPA protection walls. The male housing has TPA protection ribs.

Method of operating a connector apparatus having a female connector assembly and a male connector assembly. The female connector assembly includes a female housing, a connector position assurance (CPA) member for assuring the engagement of the male connector assembly with the female connector assembly, and a first terminal position assurance (TPA) member for assuring that terminals for the female connector assembly are positioned properly. The female housing further includes a connector latch used to securely hold together a connector apparatus. The female housing has TPA protection ribs and CPA protection walls. The male housing has TPA protection ribs.

An electrical connector includes an insulative housing and a plurality of contacts. Each contact has a retaining section, a mating section and a crimping section, the insulative housing defines a positioning groove communicated with contact-receiving passageways, the retaining section is provided with an elastic retaining arm extending backwards, a pair of cutouts on both sides of the retaining arm along a transverse direction, and a pair of limiting walls exposed in the cutouts and the positioning groove. When the contacts assembled to the relative contact-receiving passageways, each retaining arm is abutting against a rear inner surface of the positioning groove via a free end thereof to prevent the contact moving backwards, the electrical connector further comprises a retainer, and the retainer defines a plurality of limiting blocks extruding into the positioning groove and the corresponding cutouts, and the limiting blocks are abutting against the relative limiting walls.

The coupling members are positioned so as to span both paired housing halves and extend across the multiple connecting units in the direction of coupling of the connecting units, while, at the same time, having pairs of engaging portions engaging the respective housing halves of each connecting unit 10, and each of the paired housing halves has engageable portions engaging the corresponding engaging portions both in the direction of connection to counterpart connector components and in the direction of coupling.

A smart breakaway electrical connector disconnects a powerline at a designed tensile load, detects the break, and wirelessly communicates the precise location of the break to repair dispatchers. Mating male and female housings hold the internal electrical connection points together. Locking arms pivotally connected to the female connector interlock by detent with the male connector and spring force on the locking arms is used to prevent disengagement of the detent until the design tensile force is exceeded. Photovoltaics combined with rechargeable batteries ensure power availability when the line is disconnected and utility power is unavailable.
