Fig. 1 is a schematic view of a light bar and a connector according to an embodiment of the utility model. As shown in fig. 1, both ends of the light bar 1 include end connectors 11. The light bar 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. 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 connector 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 connector 11 of the light bar 1, and the light bar electrical connection interface 211 can be electrically connected to the end connector 11 of the light bar 1.

In fig. 1, reference numeral 201 merely identifies one light bar connection window for convenience 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. It should be noted that the shape of the connector is not limited to a regular prism shape, and other shapes such as a cylindrical shape or a tapered shape may be adopted. The light bar connecting windows can be arranged at the upper end part of the cylindrical surface or the conical surface at equal intervals.

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 side 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 connecting 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 the present embodiment, the mechanical connection between the end connector 11 of the light bar 1 and the partition walls 202a and 202b of the connector 2 can be realized by a snap structure. Specifically, a fixing groove may be provided on each of the partition walls 202a, 202 b. When the end connector 11 of the light bar 1 is inserted into the light bar connection window 201, the light bar buckles 111 on both sides of the end connector 11 are respectively embedded into the fixing grooves on the partition walls 202a and 202b on both sides, so as to form a mechanical connection. It should be 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 hooks 111. In fact, since two adjacent light bar connection windows 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, 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 buckles 111 at both sides of the end connector 11 of each lamp strip need to be set to be staggered with each other so as to share the same fixing groove with the adjacent lamp strips when the lamp strip connection 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 plate 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 plate 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 may include three pads for electrical power connection, ground connection, and control signal connection, 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 the present 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 for the light bars are provided on the upper PCBA board, respectively for establishing electrical connection with the light bars inserted in six different directions.

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 retainer 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 latch 261 passes through the upper through hole 212 to be engaged with the upper latching member 203. The number of the lower connecting buckles 261, the upper through holes 212 and the upper catching pieces 203 can be three, so as to form three sets of jogged 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 fixing member 26 may close the upper portion of the main 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 key pad 262, a key PCBA board, and lower connection tabs 263 electrically connected to the key 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 keypad on the upper mount 26. 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.

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 connecting 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. 7 and 8 are an exploded view and a connection view of a connector according to an embodiment of the present invention, respectively. In fig. 7 and 8, the two connectors are electrically connected by the two upper fixtures 26 and the cable 264, thereby forming a lighting system. The two connectors are referred to as a first connector and a second connector. The main body of the first connector is mounted with a first upper fixture and establishes electrical connection with the first upper fixture. The second connector has a second upper fixing member mounted on a main body thereof and is electrically connected to the second upper fixing member. The first upper fixture and the second upper fixture are electrically connected by a cable 264, so that the first connector and the second connector are electrically connected.

As shown in fig. 7, the upper fixture 26 includes a lower connection fitting 263, and the upper PCBA board 21 is provided with an upper extension interface 213. When the upper fixing member 26 is mounted above the main body 20, the lower connection terminals 263 establish electrical connection with the upper expansion interface 213. In the present embodiment, the upper connection contacts 263 are four pogo pins (pogopins), and the upper expansion interface 213 may include three sets of pads circumferentially disposed at a pitch of 120 degrees. Each group of pads comprises four pads respectively used for establishing power connection, grounding connection, control signal connection and position detection connection with four spring ejector pins (Pogopin). The upper fixture 26 may be mounted above the body 20 of the connector in three rotational positions spaced 120 degrees apart. In each rotational position, four Pogopin pins (pogopins) are able to establish electrical connection with a set of pads. Therefore, the mounting position of the upper fixture 26 can be judged by identifying the pad establishing the position detection connection. The lower connector 263 (e.g., including four pogo pins) of the upper fixture 26 is electrically connected to the cable 264. The cable 264 extends from the inside of the upper fixture 26 to the outside of the upper fixture 26, and then enters the inside of the other upper fixture and is electrically connected to the lower connection terminal inside the other upper fixture. Thus, the cable 264 can connect the lower connection tabs of two identical upper fixtures 26. As shown in fig. 8, when the two upper fixtures 26 are mounted above the main bodies of the two connectors, respectively, the cable 264 between the two upper fixtures 26 can electrically connect the two connectors so as to transmit power and signals between the two connectors. When a light bar is used to connect two connectors, the two connectors must be in the same plane and fixed from each other. When the two connectors are connected using the cable 264, since the cable 264 is flexible, the relative positions of the two connectors can be freely set so as to achieve a desired lighting effect.

In the embodiment shown in fig. 7 and 8, the upper fixture 26 is fixed above the main body 20 of the connector by a lower connection catch 261 projecting downward. The snap connection structure between the lower connection snap 261 of the upper fixture 26 and the main body 20 of the connector has been described above in detail with reference to fig. 2 and 3A, and will not be described again. Thus, various embodiments of the present invention have been described in detail. Some details well known in the art have not been described in order to avoid obscuring the concepts of the present invention. From the above description, it will be fully apparent to those skilled in the art how the technical solutions of the present invention can be implemented.

Although some specific embodiments of the present invention have been described in detail by way of illustration, it should be understood by those skilled in the art that the above illustration is only for the purpose of illustration and is not intended to limit the scope of the utility model. It will be understood by those skilled in the art that various changes may be made in the above embodiments or equivalents may be substituted for elements thereof without departing from the scope and spirit of the utility model.
