This application claims the priority benefit of China application serial no. 201720447668.X, filed on Apr. 26, 2017. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of specification.
The invention relates to a connector, and more particularly relates to a connector applied to lighting fixtures.
Existing street lights (mainly in North America) mostly adopt a connector of NEMA 7 (ANSI 136.41) specification, connecting a control component to the connector of ANSI 136.41 specification, such that the control component connects to an internal circuit of the street light through the connector, so as to achieve a purpose of controlling the street light. Currently, the connector of ANSI 136.41 specification only has 7 pins in total, and does not have spare pins providing for definition of a control means and transmission of a high frequency signal, resulting in existing street lights not being easily updated to smart network control. If existing connectors of ANSI 136.41 specification were to be completely replaced, it would not take a short time to achieve and would require exceedingly high costs.
The invention provides a connector having an effect of transmitting a high frequency signal and compatible with current light fixtures (such as street lights).
The connector of the invention is suitable to be disposed on a lighting fixture. The connector includes an insulated housing, four connecting terminals, three pins, and a plug. The insulated housing has a containing space and a disposing surface, and the disposing surface is located in the containing space. The connecting terminals are separately disposed in the containing space of the insulated housing and located on the disposing surface. The pins are separately disposed in the containing space of the insulated housing, and extend from the disposing surface toward a direction away from the disposing surface, and the connecting terminals surround the pins. The plug is disposed in a center of the containing space of the insulated housing and located on the disposing surface. The plug includes a plurality of conductive rings, the conductive rings are separately arranged along the direction away from the disposing surface, and the pins surround the plug.
In an embodiment of the invention, a first perpendicular height from each of the connecting terminals to the disposing surface is less than a second perpendicular height from each of the pins to the disposing surface, and a third perpendicular height from the plug to the disposing surface is less than the second perpendicular height and greater than the first perpendicular height.
In an embodiment of the invention, the pins include two first pins and one second pin, a width of the second pin being greater than a width of each of the first pins.
In an embodiment of the invention, the conductive rings transmit a signal using an Internet of Things communication protocol.
In an embodiment of the invention, the connector further includes a base, four connection pads, three pin slots, and a plug slot. The base is assembled on the insulated housing and has a connection surface. The connection pads are disposed on the connection surface of the base, and the connecting terminals connect to the connection pads. The pin slots are disposed on the connection surface of the base, and the pins are respectively plugged into the pin slots. The plug slot is disposed on the connection surface of the base and has a plurality of conductive spring sheets. The plug is plugged into the plug slot, such that the conductive rings respectively contact the conductive spring sheets.
In an embodiment of the invention, an external diameter of the base is less than an internal diameter of the insulated housing, and a portion of the base is located in the containing space of the insulated housing.
In an embodiment of the invention, the connector further includes a plurality of transmission pins. The transmission pins are disposed on another side of the base relatively away from the connection surface, and electrically connected to the connection pads, the pin slots, and the plug slot, respectively.
In an embodiment of the invention, the connector further includes a control unit. The control unit is disposed in the insulated housing, the control unit including a light sensor or a wireless signal receiver.
In an embodiment of the invention, the connector further includes an Internet of Things device, disposed in the insulated housing.
In an embodiment of the invention, the plug is a cylindrical plug.
Accordingly, in the design of the connector of the invention, besides the existing four connecting terminals and three pins, a plug is further included, and the plug includes the plurality of conductive rings. Therefore, compared to a connector of traditional ANSI 136.41 specification having only 7 pins, the connector of the invention further has the plug, the conductive rings thereof providing for definition of a control means and transmission of the high frequency signal. Furthermore, since the connector of the invention adds a plug based on a connector of existing ANSI 136.41 specification, the connector of the invention is compatible with existing lighting fixtures.
To make the above and other features and advantages of the invention more comprehensible, embodiments accompanied with drawings are described in detail as follows.
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. The drawings illustrate exemplary embodiments of the invention and, together with the description, serve to explain the principles of the invention.

Furthermore, the connector 100 of the embodiment further includes a plurality of transmission pins 190 disposed on another side of the base 150 relatively away from the connection surface 152, and electrically connected to the connection pads 160, the pin slots 170, and the plug slot 180, respectively. The transmission pins 190 is plugged into the lighting fixture and is configured to transmit a signal. In addition, the connector 100 of the embodiment further includes a control unit 200 disposed in the insulated housing 110, wherein the control unit 200 is, for example, a light sensor or a wireless signal receiver. By sensing an environmental brightness or receiving a signal, the control unit 200 may switch a lighting state or an off state of the lighting fixture. More specifically, the connector 100 of the embodiment further includes an Internet of Things device 300 disposed in the insulated housing 110, wherein the Internet of Things device 300, for example, adopts the Internet of Things communication protocol and transmits the high frequency signal through the conductive rings 142 of the plug 140.
In brief, the connector 100 of the embodiment includes at least 11 pins, namely the four connecting terminals 120, the three pins 130, and the four conductive rings 142. Therefore, compared to a connector of traditional ANSI 136.41 specification having only 7 pins, the connector 100 of the embodiment further has at least 4 pins (namely, the conductive rings 142) providing for definition of a control means and transmission of the high frequency signal. In addition, the conductive rings 142 can respectively be, for example, a VBUS connection point of a standard universal serial bus (USB), a D− connection point, a D+ connection point, and a ground connection point, and the conductive rings 142 transmit the high frequency signal using the Internet of Things communication protocol, thus improving a range of application of the connector 100. Furthermore, since the connector 100 of the embodiment adds a plug 140 based on a connector of existing ANSI 136.41 specification, the connector 100 of the embodiment is compatible with existing lighting fixtures.
In summary of the above, in the design of the connector of the invention, besides the existing four connecting terminals and three pins, a plug is further included, and the plug includes the plurality of conductive rings. Therefore, compared to a connector of traditional ANSI 136.41 specification having only 7 pins, the connector of the invention further has the plug, the conductive rings thereof providing for definition of the control means and transmission of the high frequency signal. Furthermore, since the connector of the invention adds a plug based on a connector of existing ANSI 136.41 specification, the connector of the invention is compatible with existing lighting fixtures.
