Referring to fig. 1 and fig. 2, a flexible light bar 100 is provided in a first embodiment of the present application. Soft light bar 100 includes: a lamp tube 110, a printed circuit board 120, a plurality of conductor pins 130, an adsorbed piece 140 and an adapter 150.

Tube 110 is tubular to accommodate the internal structure of light bar 100.

The printed circuit board 120 is disposed in the lamp tube 110. A plurality of signal lines (not shown) are provided on the printed circuit board 120. Specifically, the printed circuit board 120 is used to arrange a power supply circuit for supplying power to the light source (not shown) of the flexible light bar 100. The plurality of signal lines are, for example, positive signal lines, negative signal lines, differential signal lines, and the like. The specific arrangement of the power and signal lines on the printed circuit board 120 is prior art and will not be described in detail herein.

A plurality of conductor pins 130 are provided at the end of the printed circuit board 120 in the length direction, and each conductor pin 130 is electrically connected to a respective corresponding signal line. Specifically, the flexible light bar 100 is usually processed into a long strip shape by extrusion molding, and thus, the light tube 110 and the printed circuit board 120 are both long strip shapes. The conductor pin 130 is provided at least one end in the longitudinal direction of the printed circuit board 120. As shown in fig. 2, in the present embodiment, a plurality of conductor pins 130 are sequentially arranged in a radial direction of the lamp tube 110. The number of the conductor pins 130 may be four, five, eight, etc., and the specific number may be set according to actual needs. Each of the conductor pins 130 corresponds to one signal line, respectively, and each of the conductor pins 130 is electrically connected to the signal line corresponding thereto, respectively.

The attracted member 140 is disposed at an end of the printed circuit board 120 in the length direction. Specifically, the attracted member 140 may be connected to the end of the printed circuit board 120 by various means such as adhesion, clearance fit, and the like.

As shown in fig. 1 and 2, the adapter 150 includes a magnet piece 151 and an adapter structure 152 connected to the magnet piece 151. The magnet member 151 is used to adsorb the attracted member 140. The adapting structure 152 has a first surface (not shown) and a second surface 1522 that are oppositely disposed. The first surface is provided with a plurality of mutually independent and spaced apart conductive areas (not shown). The second surface 1522 is provided with a plurality of mutually independent and spaced conductive regions 1522 a. The conductive regions on the first surface correspond to and are electrically connected to the conductive regions 1522a on the second surface one to one. When the magnet member 151 is attached to the attached member 140, the conductive pins 130 can be engaged with the first surface or the second surface 1522, so that each conductive pin 130 is electrically connected to a corresponding conductive region.

Specifically, as shown in fig. 1, in the present embodiment, the adapting structure 152 is an adapting plate. The magnet 151 is annular and is disposed on the adapting structure 152. The magnet piece 151 and the adapter plate may be connected by a clearance fit. The material used for the magnet piece 151 may be a high boron magnet. The attracted member 140 may be a magnet member or an iron member, so that the magnet member 151 can attract the attracted member 140. As shown in fig. 2, the attracted member 140 is a plate-like member, and thus may be a magnet piece or an iron piece.

In this embodiment, the first surface (not shown) and the second surface 1522 are two opposite surfaces of the interposer. The conductive areas on the first surface may be formed by laying copper foil on the interposer. The conductive regions 1522a on the second surface 1522 may be formed by laying copper foil on the interposer. The conductive regions on the first surface can be electrically connected with the corresponding conductive regions 1522a on the second surface 1522 by forming vias (not shown) on the interposer.

When the magnet element 151 and the attracted element 140 are attracted, the conductor pin 130 can be matched with the first surface or the second surface 1522, so that the conductor pin 130 can contact the conductive region 1522a on the first surface or the second surface 1522, and the conductor pin 130 can be electrically connected with the corresponding conductive region.

As shown in fig. 1, two adjacent flexible light bars 100 can be connected through an adapter 150. The lamps 110 of the two flexible light bars 100 can be respectively placed at different sides of the adapter 150, and then one end of the magnet element 151 is attached to the attached element 140 of one of the flexible light bars 100 (located at the upper right in fig. 1), and the other end of the magnet element 151 is attached to the attached element 140 of the other flexible light bar 100 (located at the lower left in fig. 1), so that the two flexible light bars 100 can be quickly connected through the magnet element 151. When the magnetic elements 151 are respectively attached to the attached elements 140 of the two flexible light bars 100, the first surface of the adapting structure 152 is engaged with the conductive pin 130 of one of the flexible light bars 100 (located at the upper right in fig. 1), and the conductive pin 130 of the flexible light bar 100 can be electrically connected to the corresponding conductive region on the first surface, the second surface 1522 of the adapting structure 152 is engaged with the conductive pin 130 of the other flexible light bar 100 (located at the lower left in fig. 1), and the conductive pin 130 of the flexible light bar 100 can be electrically connected to the corresponding conductive region 1522a on the second surface 1522. Because the conductive regions on the first surface are in one-to-one correspondence with the conductive regions 1522a on the second surface and electrically connected, each conductor pin 130 of the two flexible light bars 100 is electrically connected to the corresponding conductive region, so that the corresponding conductor pins 130 of the two flexible light bars 100 can be electrically connected through the adapting structure 152, and thus the corresponding signal lines of the two flexible light bars 100 can be correctly butted and conducted.

In an embodiment, the conductive pins 130 and the attracted members 140 are disposed at both ends of the flexible light bar 100 in the length direction, so that both ends of each flexible light bar 100 in the length direction can be respectively connected to other flexible light bars 100 through the adapters 150.

In one embodiment, the conductor pin 130 is a pogo pin. It is understood that the pogo pin has an elastic force and can be elongated or shortened by being elastically deformed. By arranging the conductor pin 130 as a pogo pin, when the conductor pin 130 contacts with the conductive region 1522a on the first surface or the conductive region 1522 on the second surface 1522, the conductor pin 130 can be reliably contacted with the conductive region 1522a on the first surface or the conductive region 1522 on the second surface 1522 under the elastic force of the conductor pin 130, and thus, the conductor pin 130 can be ensured to be reliably electrically connected with the conductive region 1522a on the first surface or the conductive region 1522 on the second surface 1522.

The specific structure of the bullet needle is the prior art, and is not described herein again.

As shown in fig. 1 and 2, in the present embodiment, the attracted member 140 is sheet-shaped. The attracted member 140 is attached to an end of the printed circuit board 120. The absorbed member 140 is provided with a first avoiding hole 101. The conductor pin 130 passes through the first avoidance hole 101, so that the first avoidance hole 101 can function to avoid the conductor pin 130. One end of the conductor pin 130 penetrating through the first avoidance hole 101 can be electrically connected to the conductive region on the first surface or the second surface 1522.

In one embodiment, the conductive region on the first surface is an annular region, and the plurality of conductive regions on the first surface are sequentially arranged around from inside to outside. The conductive region 1522a on the second surface 1522 is an annular region, and the plurality of conductive regions 1522a on the second surface 1522 are sequentially disposed around from inside to outside. When the lamp 110 and the adapter 150 rotate relatively around the axial direction of the lamp 110, the conductor pins 130 can rotate along the annular region formed by the corresponding conductive region.

As shown in fig. 2, in this embodiment, each conductive region 1522a on the second surface 1522 is an annular region, and inner diameters of the annular regions corresponding to the plurality of conductive regions 1522a are sequentially increased and sequentially arranged from inside to outside in a surrounding manner, so as to form a layer-by-layer surrounding structure. Similarly, the conductive region on the first surface has substantially the same structure as the conductive region 1522a on the second surface 1522.

When the magnet member 151 is attached to the attached member 140, each conductor pin 130 is engaged with the first surface or the second surface 1522 so as to be in contact with the corresponding conductive region. When the lamp 110 and the adapter 150 rotate relatively around the axial direction of the lamp 110, the conductor pins 130 can rotate along the annular region formed by the corresponding conductive region. It can be understood that when the conductor pin 130 rotates along the annular region formed by the corresponding conductive region, the conductor pin 130 always moves in the annular region, so that the conductor pin 130 can always keep electrical connection with the corresponding conductive region, and it can be known that, when the lamp tube 110 and the adapter 150 are at any relative angle around the axial direction of the lamp tube 110, the conductor pin 130 can keep electrical connection with the respective corresponding conductive region. Therefore, when two adjacent flexible light bars 100 are connected through the adaptor 150, the light tubes 110 of the two flexible light bars 100 are butted at any relative angle, and the conductor pins 130 of the two flexible light bars 100 can be electrically connected with the corresponding conductive areas, so that the corresponding signal lines of the two flexible light bars 100 can be correctly butted and conducted, and the two adjacent flexible light bars 100 can be conveniently and rapidly connected.

As shown in fig. 1, in an embodiment, the lamps 110 are circular tubes, so that when two adjacent flexible light bars 100 are connected by the adaptor 150, the structural shape formed by connecting the two adjacent flexible light bars 100 is not changed when the lamps 110 of the two flexible light bars 100 are butted at any relative angle or rotate relatively.

As shown in fig. 2, in an embodiment, the flexible light bar 100 further includes a plug 160 for plugging the end of the light tube 110 along the length direction. The conductive pin 130, the attracted member 140, and the printed circuit board 120 are located in the plug 160 at ends thereof in the longitudinal direction.

Specifically, as shown in fig. 2, the stopper 160 includes a tube 161 and a cover 162. The cover 162 is fixedly connected to the tube 161 and seals the tube 161. The plug 160 may be integrally formed with the conductor pin 130, the attracted member 140, the printed circuit board 120 and the lamp tube 110 by injection molding, so that the plug can be reliably connected to the lamp tube 110, and the ends of the conductor pin 130, the attracted member 140 and the printed circuit board 120 in the length direction are plugged inside the plug 160.

The material used for the plug 160 is the same as the material used for the lamp tube 110, so that a better blending effect with the lamp tube 110 can be achieved.

As shown in fig. 2, in one embodiment, the plug 160 is provided with a second relief hole 102, and the conductor pin 130 passes through the second relief hole 102. Specifically, the conductor pin 130 passes through the second avoidance hole 102 after passing through the first avoidance hole 101, and one end of the conductor pin 130 passing through the second avoidance hole 102 can be electrically connected to the conductive region on the first surface or the conductive region on the second surface 1522. In this embodiment, the number of the second avoiding holes 102 is multiple, and the second avoiding holes 102 correspond to the conductor pins 130 one to one, and the conductor pins 130 are adapted to the second avoiding holes 102, so that the conductor pins 130 can block the second avoiding holes 102 when the conductor pins 130 are matched with the second avoiding holes 102, thereby facilitating the plugs 160 to perform a better blocking function.

It can be understood that the magnet 151 and the attracted member 140 are located on different sides of the cover 162, and therefore, the magnet 151 and the attracted member 140 are attracted to each other with the cover 162 interposed therebetween, that is, when the magnet 151 and the attracted member 140 are attracted to each other by the attraction force between the magnet 151 and the attracted member 140, the cover 162 is sandwiched between the magnet 151 and the attracted member 140.

As shown in fig. 2, in one embodiment, the adapter 150 further includes a housing 153. The magnet piece 151 and the adapting structure 152 are located within the housing 153. Specifically, the housing 153 may be integrally formed with the magnet piece 151 and the adapting structure 152 by injection molding.

As shown in fig. 2, in an embodiment, the housing 153 can be sleeved on the plug 160 and adapted to the plug 160, so that when the two light bars 100 are connected through the adapter 150, the plug 160 is inserted into the housing 153, so that the magnet 151 and the adsorbed piece 140 are adsorbed, thereby facilitating the quick connection of the two light bars 100.

Specifically, the plug 160 is adapted to the housing 153, so that when the plug 160 is inserted into the housing 153, the plug and the housing are tightly engaged, thereby achieving a good waterproof effect.

The material used for the housing 153 may be an elastic material, such as silicone, so that when the plug 160 is inserted into the housing 153, the outer surface of the plug 160 abuts against the inner surface of the housing 153, and the elastic restoring force of the housing 153 can ensure that the housing 153 and the plug 160 are reliably matched, thereby providing good sealing performance.

In one embodiment, the outer diameter of the housing 153 is the same as the outer diameter of the lamp tube 110, so that when the plug 160 is inserted into the housing 153 and the magnet 151 is attached to the attached member 140, the housing 153 and the lamp tube 110 can be perfectly and seamlessly butted.

Referring to fig. 3, a flexible light bar 200 is provided in a second embodiment of the present application. The flexible light bar 200 of the second embodiment includes a light tube 210, a printed circuit board 220, a plurality of conductive pins (not shown), a attracted member 240, an adapter 250, and a plug 260. The basic structure of the flexible light bar 200 of the second embodiment is substantially the same as the basic structure of the flexible light bar 100 of the first embodiment, and the description thereof is omitted. The following description focuses on the differences between the flexible light bar 200 of the second embodiment and the flexible light bar 100 of the first embodiment.

In the present embodiment, the adapter structure includes a first adapter plate 252a and a second adapter plate 252 b. The first adapter plate 252a and the second adapter plate 252b are respectively disposed on different sides of the magnet 251. The first surface (not shown) is the surface of the first interposer plate 252a facing away from the second interposer plate 252b, and the conductive regions on the first surface are located on the first interposer plate 252 a. As shown in fig. 5, the second surface 2522 is a surface of the second interposer 252b facing away from the first interposer 252a, and the conductive area on the second surface 2522 is located on the second interposer 252 b.

As shown in fig. 3, the magnet member 251 has a ring shape and has a through hole 204. Adapter 250 also includes a plurality of connecting wires (not shown). The connecting wires correspond to the conductive regions on the first surface and the conductive regions on the second surface 2522 one by one. The conductive regions on the first surface and the conductive regions on the second surface 2522 may be electrically connected by corresponding connection wires. The connection lead passes through the through-hole 204 of the magnet piece 251 so that both ends of the connection lead can be electrically connected to the conductive regions on the first surface and the conductive regions on the second surface 2522, respectively.

In one embodiment, the plug 260 can be sleeved on the housing 253.

Specifically, as shown in fig. 3 and 4, the cover 262 of the stopper 260 is located inside the tube 261, so that a side of the cover 262 facing away from the absorbed member 240 can leave a certain accommodating space 205. The housing 253 can be inserted into the accommodating space 205, so that the plug 260 can be sleeved on the housing 253.

The material used for the housing 253 may be an elastic material, such as silicone, so that when the plug 260 is sleeved on the housing 253, the inner surface of the plug 260 abuts against the outer surface of the housing 253, and the housing 253 can be reliably matched with the plug 260 by using the elastic restoring force of the housing 253, so that the sealing performance is good.

In this embodiment, the outer diameter of the plug 260 is the same as the outer diameter of the lamp tube 210, so that the plug 260 and the lamp tube 210 can be perfectly and seamlessly butted.

Referring to fig. 6 and 7, a third embodiment of the present application provides a flexible light bar 300. The flexible light bar 300 of the second embodiment includes a light tube 310, a printed circuit board 320, a plurality of conductive pins 330, a attracted member 340, an adapter 350, and a plug 360. The basic structure of the flexible light bar 300 of the third embodiment is substantially the same as that of the flexible light bar 200 of the second embodiment, and the description thereof is omitted. The following description focuses on differences between the flexible light bar 300 of the third embodiment and the flexible light bar 200 of the second embodiment.

As shown in fig. 6, in the present embodiment, the lamp tube 310 is a square tube.

As in the second embodiment, in the present embodiment, the adapter structure includes a first adapter plate 352a and a second adapter plate 352 b. The first adapter plate 352a and the second adapter plate 352b are respectively provided on different sides of the magnet piece 351. The first surface (not shown) is the surface of the first interposer 352a facing away from the second interposer 352b, and the conductive areas on the first surface are located on the first interposer 352 a. As shown in fig. 7, the second surface 3522 is a surface of the second interposer 352b facing away from the first interposer 352a, and the conductive region 3522a on the second surface 3522 is located on the second interposer 352 b.

As shown in fig. 7, unlike the second embodiment, in the present embodiment, the conductive regions 3522a on the second surface 3522 are not annular regions, but strip-shaped regions arranged in sequence. Similarly, the conductive regions on the first surface are not annular regions, but are strip-shaped regions arranged in sequence.

The magnet piece 351 has the through hole 304, similarly to the second embodiment. The adapter 350 also includes a plurality of connecting wires (not shown). The connecting wires are in one-to-one correspondence with the conductive regions on the first surface and the conductive regions 3522a on the second surface 3522. The conductive regions on the first surface and the conductive regions 3522a on the second surface 3522 may be electrically connected by corresponding connecting wires. The connection wires pass through the through holes 304 of the magnet piece 351 so that both ends of the connection wires can be electrically connected to the conductive regions on the first surface and the conductive regions 3522a on the second surface 3522, respectively. However, unlike the second embodiment, the magnet piece 351 is not annular, but is entirely cubic.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
