Description

Receptacle for Lighting Equipment Field of Invention The field of the invention relates to receptacles for lighting equipment, and in particular receptacles mountable in a luminaire housing, more in particular in an outdoor luminaire housing.
Background Lighting equipment for roadways, parking lots and other outdoor areas typically use plug twist- lock external modules containing different control blocks and/or sensors, e.g. a light sensor for sensing the light level of ambient light to automatically control the light sources of the lighting equipment.
For uniformity throughout the lighting industry, electrical receptacles for receiving such external modules are mostly made according to specific standards such as standards approved by American National Standards Institute, Inc. (ANSI). Such receptacles are typically mounted on the top of a housing or in an opening in the housing of the lighting equipment and are electrically connected to various components of the lighting equipment.
The receptacle has a connection interface located on an external side of the housing, so that an external module can be plugged into the receptacle to provide control for the lighting equipment.
An external module typically comprises at least three standard prongs or plug contacts which are inserted into corresponding apertures in the receptacle.
After the prongs are completely inserted, the external module is rotated to lock it in place.
The external module may comprise further contacts in the form of conductive springs for cooperating with receptacle contacts in the form of conductive plates.
Preferably, the receptacle and the external module fulfil the requirements of the ANSI C136.10-2017 standard or of the ANSI C136.41-2013 standard or of the Zhaga Interface Specification Standard (Book 18, Edition 1.0, July 2018, see https://www.zhagastandard.org/data/downloadables/1/0/8/1/book _18.pdf). Summary The object of embodiments of the invention is to provide a receptacle socket assembly for lighting equipment which can be more easily connected to components of the lighting equipment.
According to an aspect of the invention there is provided a receptacle having a front side and a rear side.
The front side is configured for receiving electrical contacts of an external module of alighting equipment.
The receptacle houses a plurality of receptacle contacts, each receptacle contact being provided, at a front end, with a front contact portion configured for being electrically connected with a contact of the external module, and, at a rear end, with at least one wire receiving contact portion in which at least one wire is fixed. At least one receptacle contact of said plurality of receptacle contacts is provided, at said rear end, with at least two wires, such that the number of wires provided at the rear side is higher than the number of front contact portions.
By providing a receptacle with one or more receptacle contacts which are provided, at a rear end, with at least one wire receiving contact portion in which at least two wires are fixed, the number of wires provided at the rear side is higher than the number of front contact portions. In other words a front contact portion is electrically connected to at least two wires. In that manner the same front 19 contact portion (which is connected to an electrical contact of the external module) can be connected to different components of a luminaire in a convenient manner. Stated differently, embodiment of the invention allow to “duplicate” or “split” a receptacle contact so that it can be connected to multiple components in the luminaire in a convenient manner. Embodiments of the invention may have one or more “duplicated” or “split” receptacle contacts. Note that it is also possible to have a front contact portion which is electrically connected to three or more wires, such that the receptacle contact is “triplicated” or “split” in even more wires.
The receptacle can be fixed to a housing of the lighting equipment, such that the electrical contacts of an external module can be plugged in the front side to be in electrical contact with the front contact portions, and such that the wires are available inside the housing for being connected to different luminaire components. The external module may comprise any one or more of the following: a sensor (e.g. a light sensor, a motion sensor, a passive infrared sensor, etc.), communication circuitry, control circuitry, protection circuitry (e.g. an SPD or a fuse), an actuator, etc. More generally the external module may comprise any component that needs to be powered, any component involved in the transmission and/or reception of signals, any component completing the circuitry inside the luminaire head, such as protection circuitry, etc.
It is further noted that the external module may be configured to receive a further external module. In other words, a stack of interconnected external modules may be arranged in the receptacle, wherein some functionalities may be included in a first external module and other functionalities in a second external module. In that manner, the system is given an extra degree of modularity.
Also, it is noted that it is possible to provide one or more functionalities in the receptacle itself, such as a sensor, communication circuitry, control circuitry, protection circuitry (e.g. an SPD or a fuse), an actuator, etc.
According to an exemplary embodiment, at least one receptacle contact of said plurality of receptacle contacts is provided at the rear end with a first wire receiving contact portion in which a first wire is received and with a second wire receiving contact portion at a distance of said first wirereceiving contact portion, in which a second wire is received. The first and the second wire receiving portion are located at a distance of each other, and are both connected with the same front contact portion of the receptacle contact. Preferably, the front contact portion and the corresponding first and second wire receiving portions are integrally formed. In that manner, the receptacle contact itself is “duplicated” or “split” so that a first and second wire can be received in the respective first and second wire receiving portions. In that manner, the connection of the receptacle contact to two wires can be realized in an effective manner. Embodiments of the invention may have one or more receptacle contacts which are “duplicated” or “split” in the above described manner.
In further developed embodiments, at least one receptacle contact of said plurality of receptacle contacts may be provided at the rear end with more than two wire receiving portions for receiving more than two wires.
In other embodiments, there may be provided two or more wires in a single wire receiving portion.
According to an exemplary embodiment, the plurality of receptacle contacts comprises a plurality of first receptacle contacts and optionally one or more second receptacle contacts.
In an exemplary embodiment, seen in a radial direction around a central axis of the receptacle, the plurality of first receptacle contacts are positioned further away from the central axis than the one or more second receptacle contacts.

Optionally, one of the plurality of first receptacle contacts and/or one of the one or more second receptacle contacts may be used for carrying both a power signal and a data or control signal.
In another variant, no second receptacle contacts are provided, and the plurality of first receptacle contacts comprises both one or more contacts for carrying a power signal as well as one or more contacts for carrying a data or control signal, wherein optionally one or more contacts may be used for carrying both power and data/control signals. In such an embodiment, typically, at least three first receptacle contacts are provided of which two carry power signals and one a data or control signal. In yet another variant without second receptacle contacts, the plarality of first receptacle contacts comprises only receptacle contacts for carrying power supply signals, e.g. two DC terminal contacts, of which one may be a ground terminal. In a further variant, the one or more second receptacle contacts may be used for carrying one or more data or control signals, and the plurality of first receptacle contacts may be used for carrying power signals. The one or more second receptacle contacts may then be e.g. a central pin terminal surrounded by a cylindrical contact terminal (e.g. an RCA connector). The skilled person understands that other combinations are possible, and that one or more receptacle contacts may be used for carrying both a power signal and a control/data signal and/or that control messages may be included in a power signal. Preferably, at least one receptacle contact of said plurality of first receptacle contacts is duplicated, i.e. is provided with at least two wires, and if one or more second receptacle contacts are present, preferably at least one receptacle contact of said one or more second receptacle contacts is duplicated, i.e. is provided with at least two wires. In that manner, any electrical contacts of the external module that need to be connected to more than one component of the lighting equipment can be connected without the need for additional connection devices inside the lighting equipment. Alternatively, only one or more receptacle contacts of the plurality of first receptacle contacts or only one or more second receptacle contacts are duplicated.
Preferably, the plurality of first receptacle contacts extends substantially along a first cylindrical surface around the central axis. When more than one second receptacle contact is present, the two or more second receptacle contacts may extend substantially along a second cylindrical surface around the central axis. However, it is also possible to have two second receptacle contacts in the form of a central pin and a surrounding cylindrical contact (e.g. an RCA connector) arranged centrally at the front side of the receptacle. Also, if only one second receptacle contact is provided, it may be arranged centrally. Alternatively, it may be arranged externally of the first cylindrical surface, further away of the central axis of the receptacle. If no second receptacles are present, typically at least three first receptacle contacts are present, more preferably four receptacle contacts. In an exemplary embodiment, the front contact portions of the plurality of first receptacle contacts extend flush with the front side of the receptacle. For example, the front contact portions of the plurality of receptacle contacts fulfil the requirements of the ANSI C136.41-2013 standard or the ANSI C136,10-2017 standard.
In another exemplary embodiment, the front contact portions of the plurality of first receptacle contacts are accessible via apertures in the front side of the receptacle and extend near the front side of the receptacle.

In such an embodiment, typically, at least four wires are provided of which at least two carry power signals and at least one a data or control signal.
In a further variant, the one or more second wires may be used for carrying one or more data or control signals, and the plurality of first wires may be used for carrying power signals.
The skilled person understands that other combinations are possible, and that one or more receptacle contacts may be used for carrying both a power signal and a control/data signal and/or that control messages may be included in a power signal.
According to an exemplary embodiment, the front contact portions of the plurality of receptacle contacts extend at or near the front side of the receptacle.
Preferably, the rear side of the receptacle is provided with a plurality of ducts for receiving the wire receiving contact portions. The plurality of ducts may comprise a plurality of first dacts and optionally one or more second ducts.
In an exemplary embodiment, seen in a radial direction around the central axis of the receptacle, the plurality of first ducts are positioned further away from the central axis than the one or more second ducts. The plurality of first ducts may have a length, seen in an axial direction,
which is different from a length of the one or more second ducts.
In that manner, a length of the plurality of ducts may be suitably adjusted to the length of the receptacle contacts.
Preferably, the plurality of first ducts extends substantially along a first cylindrical surface around the central axis.
When more than one second duct is present, the two or more second ducts may extend substantially along a second cylindrical surface around the central axis.
However, it is also possible to have two second ducts in the form of a central duct for a central pin and a surrounding duct for a surrounding contact {e.g. such that an RCA connector is formed). Also, if only one second duct is provided, it may be arranged centrally.
Alternatively, it may be arranged externally of the first cylindrical surface, further away of the central axis of the receptacle.
If no second ducts are present, typically at least three first ducts are present, more preferably ducts.
According to an exemplary embodiment, the receptacle has a housing comprising a substantially cylindrical front portion at the front side of the receptacle, and a rear portion protruding rearward at the rear side of the substantially cylindrical front portion.
