The word "comprising" or "comprises", and the like, means that the element preceding the word covers the element listed after the word, and does not exclude the possibility that other elements are also covered. "upper", "lower", "left", "right", and the like are used only to indicate relative positional relationships.

Fig. 1 is a schematic view of a light bar and a connector according to an embodiment of the invention. As shown in fig. 1, both ends of the light bar 1 include end connectors 11. The lamp strip 1 is connected with the connector 2 through the end connector 11. The connector 2 includes a main body 20 having a columnar shape and an upper PCBA board 21 provided inside the main body. A plurality of light bar connection windows 201 with different orientations are formed on the side surface of the main body 20, and are used for receiving the end connection members 11 of the light bars 1. The upper PCBA board 21 is provided with a light bar electric connection interface 211 for establishing connection with the end connection part 11 of the light bar 1. The number of the light bar electric connection interfaces 211 is the same as that of the light bar connection windows 201. When the end connection member 11 of the light bar 1 is inserted into the light bar connection window 201, the main body 20 can be mechanically connected to the end connection member 11 of the light bar 1, and the light bar electrical connection interface 211 can be electrically connected to the end connection member 11 of the light bar 1, so that the electrical connection and the control signal connection between the connector 2 and the light bar 1 are realized.

In fig. 1, reference numeral 201 identifies only one light bar connection window for ease of understanding. However, five other light bar connection windows identical to light bar connection window 201 are clearly shown in fig. 1. Therefore, the connector 2 in the present embodiment can simultaneously connect six light bars. Since the orientation of each light bar connection window is different, the connector 2 can connect the light bars in six different directions.

In the present embodiment, the connector 2 has a regular hexagonal prism shape. The light bar connection window 201 is provided at the upper end of six sides of the regular hexagonal prism shaped body 20. In other embodiments, the shape of the connector may be a regular prism having a number of sides of not less than three, such as a regular triangular prism, a regular quadrangular prism, a regular pentagonal prism, or the like. The upper end of each side of the regular prism-shaped connector can be provided with a light bar connection window. Each side face can be provided with a light bar connecting window, or a plurality of light bar connecting windows are arranged at intervals in the height direction of each side face and used for connecting light bars at different heights. For example, a light bar attachment window may be provided at each of the upper and lower ends of each side for attaching two light bars at two different heights. It should be noted that the shape of the connector is not limited to the regular prism shape, and other shapes such as a cylindrical shape or a tapered shape may be adopted. The light bar attachment windows may be disposed on a cylindrical or conical surface at equal angular intervals about a central axis that is cylindrical or conical. For example, when the number of the light bar attachment windows is 3, the light bar attachment windows may be arranged on a cylindrical surface or a conical surface at angular intervals of 120 degrees around the central axis of the cylindrical or conical shape. When the number of the light bar connection windows is 4, the light bar connection windows may be arranged on a cylindrical surface or a conical surface at angular intervals of 90 degrees around a central axis of the cylindrical or conical shape. When the number of the light bar connecting windows is 6, the light bar connecting windows can be arranged on the cylindrical surface or the conical surface at the angular intervals of 60 degrees around the central axis of the cylinder or the cone.

In the present embodiment, the upper end portion of the prismatic main body 20 includes a plurality of

partition walls

202a,202b extending from the lateral edges of the main body 20 toward the inside of the main body 20. When the end connector 11 of the light bar 1 is inserted into the light bar connection window 201, the end connector 11 is mechanically connected to the

partition walls

202a and 202b on both sides thereof. At this time, the end connector 11 is sandwiched between the

partition walls

202a,202b on both sides, and fixed in the connected position by the

partition walls

202a,202b on both sides. It is to be noted that, for the sake of understanding,

reference numerals

202a and 202b identify only two adjacent partition walls. However, as can be clearly seen in fig. 1, six partition walls are provided in the main body 20. The six divider walls divide the upper portion of the side walls of the main body 20 into six differently oriented light bar attachment windows.

In this embodiment, the mechanical connection between the end connector 11 of the light bar 1 and the

partition walls

202a,202b of the connector 2 can be achieved by a snap structure. Specifically, each of the

partition walls

202a,202b may be provided with a fixing groove thereon. When the end connector 11 of the light bar 1 is inserted into the light bar connecting window 201, the light bar fasteners 111 at both sides of the end connector 11 are respectively embedded into the fixing slots on the

partition walls

202a and 202b at both sides to form a mechanical connection. It is understood that the width of the fixing groove on each of the

partition walls

202a,202b may be set to be greater than or equal to the width of the two light bar clasps 111. In fact, since two adjacent light bar connection windows may share one partition wall between them, the light bar buckles 111 on the end connectors 11 of two adjacent light bars may need to be received in the fixing grooves on the partition wall in the middle, and thus the width of the fixing grooves needs to be set to be greater than or equal to the width of the two light bar buckles. In addition, the positions of the lamp strip fasteners 111 at both sides of the end connector 11 of each lamp strip need to be staggered from each other, so that the same fixing groove can be shared by the adjacent lamp strips when the lamp strip connecting window is inserted. In other embodiments, two separate fixing slots may be provided on each partition wall for receiving two light bar fasteners facing the same partition wall on two adjacent end connectors 11.

Fig. 2 is an exploded schematic view of a connector according to an embodiment of the present invention. Fig. 3A, 3B, and 3C are a top view, a sectional view, and a bottom view, respectively, of the connector 2 shown in fig. 1. The connector 2 according to the embodiment of the present invention will be described in detail below with reference to fig. 2 and fig. 3A to 3C.

In the embodiment shown in fig. 2, the connector 2 includes, from top to bottom, an upper fixture 26, an upper PCBA board 21, a main body 20, a lower PCBA board 22, a lower fixture 23, a double-sided tape 24, and a lower fixture fixing screw 25.

As shown in fig. 2 and 3A, the upper PCBA board 21 has mounting grooves corresponding to the

partition walls

202a,202b of the main body 20, so that each

partition wall

202a,202b is fitted into the corresponding mounting groove when the upper PCBA board 21 is mounted into the main body 20. This kind of mounting means of going up PCBA board 21 both can strengthen the stability of the mounting structure of going up PCBA board, can increase the usable floor area of going up PCBA board 21 as far as possible again, improves the space utilization in main part 20. To further secure the upper PCBA plate 21, upper PCBA plate fixing screws 27 may be used to secure the upper PCBA plate 21 in the body 20.

In this embodiment, a light bar electrical connection interface 211 is disposed on the upper surface of the upper PCBA board 21 at a position corresponding to the light bar connection window 201. Specifically, the light bar electrical connection interface 211 can be implemented by pads disposed on the upper PCBA board. Each set of light bar electrical connection interfaces 211 can include three pads for power, ground, and control signal connections, respectively. When the end connector 11 of the light bar 1 is inserted into the light bar connection window 201, the three electrical connection contacts of the end connector 11 are electrically connected with the three pads of the light bar electrical connection interface 211, respectively, so as to receive power and control signals from the connector 2. In this embodiment, for convenience of understanding, reference numeral 211 only identifies one set of light bar electrical connection interfaces. However, as best seen in fig. 3A, six sets of electrical connection interfaces are provided on the upper PCBA board for establishing electrical connections with six different orientations of the inserted light bars.

In this embodiment, the upper PCBA board 21 further includes an upper through hole 212 thereon. In the connector 2, the main body 20 is provided with an upper catching piece 203 below the upper through hole 212. The upper through hole 212 and the upper buckling member 203 constitute an upper connecting mechanism of the connector 2 for connecting with the upper fixing member 26. The upper fixture 26 includes a lower coupling catch 261 protruding downward. The lower coupling buckle 261 can be detachably coupled with the upper coupling mechanism so that the upper fixture 26 is detachably mounted above the main body 20. As shown in fig. 3B, when the upper fixing member 26 is connected to the connector 20, the lower connecting buckle 261 passes through the upper through hole 212 to be engaged with the upper buckling part 203. The number of the lower connecting buckles 261, the upper through holes 212 and the upper buckling parts 203 can be three, so as to form three sets of embedded connection. The upper PCBA board may be further secured within the body 20 by the connection of the upper fixture 26 to the body 20. In addition, the upper fixture 26 may also enclose the upper portion of the body 20, improving the appearance of the connector 2. In fig. 2, the upper surface of the upper fixture 26 is a flat decorative surface. In the illustrated embodiment of fig. 4, the upper fixture 26 may also include a control device 262, a control PCBA board, and a lower connection tab 263 electrically connected to the control PCBA board. To accommodate the upper fixture 26 shown in FIG. 4, the upper PCBA board 21 may also be provided with an upper expansion interface 213. When the upper fixing member 26 shown in fig. 4 is mounted above the main body 20, the lower connection terminals 263 establish electrical connection with the upper expansion interface 213. The lower connection terminal 263 may specifically include three pogo pins (pogopins), and the upper expansion interface 213 may include three pads corresponding to the three pogo pins. The three pogo pins are respectively brought into contact with three pads on the upper PCBA board 21 so as to establish power connections, ground connections and control signal connections. The user can thus control the light bar via the control device 262 on the upper fixture 26. The control device 262 may be a mechanical keyboard, a touch keyboard, or a touch display screen. The user can control the connected light bars via the control device 262 to produce different lighting effects.

Three sets of upper expansion interfaces (nine pads in total) are provided on the upper PCBA board 21 shown in fig. 2, the three sets of upper expansion interfaces being spaced from each other by an angle of 120 degrees so that the upper fixture 26 can establish electrical connections with the upper PCBA board 21 in three different positions of rotation relative to the main body 20. In the embodiment of fig. 4, the upper mount 26 provides keypad control functions. In other embodiments, various sensors (e.g., sound sensor and/or light sensor) may be disposed in the upper fixing member 26 for sensing external sound and/or light conditions, so as to control the light of the light bar according to the external sound and/or light conditions.

In the embodiment shown in fig. 2, the connector 2 may also include a lower PCBA board 22. The lower side of the upper PCBA board 21 can be provided with a connecting plug, and the upper side of the lower PCBA board 22 can be provided with a connecting socket. When the upper PCBA board 21 and the lower PCBA board 22 are mounted in the main body 20, the connection plug of the upper PCBA board 21 is inserted into the connection socket of the lower PCBA board 22, so that the circuits of the upper PCBA board 21 and the lower PCBA board 22 communicate with each other. The provision of the lower PCBA board 22 in the connector 2 increases the area of the circuit board in the connector 2, so that more electrical components can be provided in the connector, thereby achieving more functions. In addition, as shown in fig. 3C, a lower extension interface 221 may be provided on a lower surface of the lower PCBA board 22 for enabling the connector 2 to be electrically connected to another device (e.g., another connector) at a lower side, thereby enabling extension of the connector 2.

In the embodiment shown in fig. 2, the lower fixture 23 is rotatably and detachably installed below the main body 20. In order to achieve the connection of the lower fixture 23 with the main body 20, the connector 2 further includes a lower connection mechanism, and the lower fixture 23 includes a rotary connector 231 extending vertically upward. The rotary connector 231 is detachably and rotatably connected to the lower connection structure. The rotary connector 231 may have a cylindrical shape and may be disposed, for example, at the center of the lower fixture 23. The upper end of the rotary connector 231 comprises a crown shaped catch. The lower connection mechanism includes a lower retaining member 204, and when the lower fixing member 23 is connected to the connector 2, the crown-shaped buckle is engaged with the lower retaining member 204. The lower retainer 204 may specifically include a plurality of annularly distributed and spaced-apart tabs for securing the crown snap in the engaged position while allowing the lower fixture 23 to rotate relative to the body 20. In this embodiment, the lower PCBA 22 has a lower through hole 222 centrally disposed therein. The rotary connector 231 of the lower fixing member 23 passes through the lower through hole 222 and then is engaged with the lower retainer 204 in the main body 20. Fig. 3B specifically shows a cross-sectional view of the rotary connector 231 and the lower retainer 204 in a connected state. In the present embodiment, the lower fixture 23 may further include a screw hole for fixing the lower fixture 23 to a surface (e.g., a wall surface) of an object on which the connector 2 is arranged by the lower fixture fixing screw 25. Optionally or alternatively, a groove can be provided below the lower fixing member 23 for adhering the double-sided adhesive tape 24. Thus, the lower fixture 23 can be fixed to a surface (e.g., a wall surface) of an object on which the connector 2 is arranged by the double-sided tape 24. Since the double-sided tape 24 is positioned in the groove below the lower fixture 23, the lower fixture 23 can be completely attached to the wall surface. When installing the connector on, for example, a wall surface, the lower fixing member 23 may be fixed to the wall surface (for example, by the lower fixing member fixing screw 25 and/or the double-sided tape 24), and then the lower fixing member 23 may be connected to the main body 20 of the connector 2. The user can rotate the position of the main body 20 of the connector 2 as desired to achieve the desired light bar connection effect.

Fig. 5 is a schematic diagram of a connector and a light bar according to an embodiment of the invention. In fig. 5, two ends of the light bar 1 are connected to two connectors 2, respectively. The left connector 2 has an upper fixing part including a key pad for controlling the light bar.

Fig. 6 is a schematic diagram of a pattern formed by a connector and a light bar according to an embodiment of the invention. In fig. 6, six connectors and six light bars are combined to form a regular hexagonal pattern. One connector is provided with a control device (such as a key keyboard, a touch keyboard or a touch display screen), and a user can control each light bar by operating the control device. The connector is also connected to the general controller 4. The general controller 4 is connected to the power supply and is configured to supply power to the connector and send control signals for controlling the lighting effect of the light bar. A processor and a computer readable storage medium may be included within the overall controller 4. The computer-readable storage medium has stored thereon a computer program which, when executed by a processor, generates a control signal for controlling the lighting effect of the light bar. The general controller 4 may also include a bluetooth and/or Wi-Fi communication module for communicating with the internet or the user's smartphone. The user can set a corresponding smart home scene and a dynamic lighting effect through an application program (APP) on the smart phone, and transmit a user instruction to the general controller 4. And the master controller 4 carries out instruction processing after receiving a user instruction and transmits a plurality of groups of control signals to each light bar, thereby realizing the lighting effect set by the user.

Not only the lower fixture 23 but also the stacking connection member 3 can be mounted below the connector 2 for stacking connection with another connector. Fig. 7 and 8 show an exploded view and a cross-sectional view, respectively, of two connectors connected by means of a superposed connection 3. As shown in fig. 7 and 8, the superposed connection piece 3 is fitted between and connects two connectors together. The connector located above the stacked connector 3 is referred to as a first connector, and the connector located below the stacked connector 3 is referred to as a second connector. The stacking connector 3 includes a stacking connector upper surface 30 and a stacking connector lower surface 31. The upper stacking connector surface 30 includes an upwardly extending upper expansion tab 301 thereon and the lower stacking connector surface 31 includes a downwardly extending lower expansion tab 311 thereon. The upper expansion joint 301 and the lower expansion joint 311 protrude from the stacking link 3 in opposite directions. The upper expansion joint 301 is electrically connected to the lower expansion interface 221 of the first connector, and the lower expansion joint 311 is electrically connected to the upper expansion interface 213 of the second connector. The upper expansion joint 301 and the lower expansion joint 311 may include three pogopin pins, respectively. The upper expansion joint 301 is in electrical communication with the lower expansion joint 311 such that the first connector is in electrical communication with the second connector for the transmission of power and control signals.

In order to determine the position and deflection angle of the stacked connector relative to the connector, each set of light bar electrical connection interfaces 211 on the connector may further include a pad for locating the position of the stacked connector. That is, each set of light bar electrical connection interfaces 211 may include four pads for electrical power connection, ground connection, control signal connection, and angular positioning of the stacked connectors, respectively. A positioning spring thimble may be provided on the superposed connector 3. When the stacking connector 3 is connected to a connector below, the positioning spring ejector pin of the stacking connector 3 is electrically communicated with the pad for angular positioning of the group of light bar electrical connection interfaces 211, so that a deflection angle of the positioning spring ejector pin of the stacking connector when connected with the positioning pad can be obtained, and the position and the deflection angle of the stacking connector relative to the connector can be further determined.
