Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a module connector for a light source module. Background Art

[0002] Traditionally, in addition to the liquid crystal layer, the main components of a liquid crystal display panel are a light-emitting layer (also known as a backlight panel). The liquid crystal layer needs to be transparent to the light-emitting layer in order to display images.

[0003] The backlight layer in the prior art is composed of a plurality of light emitting diode modules. The light emitting diodes are distributed under the liquid crystal layer, and the surface light source generated by the light emitting diodes acts on the liquid crystal layer.

[0004] Multiple LED modules are connected via flat cables. Since LCD panels come in different sizes, LED modules must be customized to suit each size, which places limitations on circuit layout design. Furthermore, if a LED module is damaged, the entire module must be replaced, which is both costly and difficult to replace.

[0005] In view of this, the present invention provides a modular connector to solve the deficiencies of the prior art. Summary of the Invention

[0006] A first object of the present invention is to provide a modular connector that is applied to one or more light strips (or light-emitting units) so that the light strips can be easily installed at any position on the cable.

[0007] A second object of the present invention is to provide an unlimited number of light strips for serial connection based on the above-mentioned modular connector, so as to be applicable to display screens of different sizes.

[0008] A third object of the present invention is to expose or hide a portion of the cable in the connector based on the above-mentioned modular connector.

[0009] A fourth object of the present invention is to provide a plurality of locking portions and a plurality of snap-fitting portions based on the above-mentioned modular connector to fix the connector to the light bar or unlock it from the light bar to facilitate assembly and maintenance.

[0010] A fifth object of the present invention is to provide an indicator hole and an indicator member based on the above-mentioned modular connector, and to determine the state of the cable and seat assembly by whether the indicator member is exposed in the indicator hole.

[0011] The sixth object of the present invention is to provide a receiving portion on the second connecting component based on the above-mentioned module connector to connect to the transmission portion of the circuit board, and by combining the receiving portion and the transmission portion, the cable is electrically connected to the circuit board.

[0012] To achieve the above and other objectives, the present invention provides a modular connector that transmits a signal and power between a light bar and a circuit board by connecting a plurality of cables. The light bar includes a plurality of first terminals, and the circuit board includes a plurality of second terminals. A light source connection module includes a first connecting component and a second connecting component. The first connecting component is capable of connecting the light bar and arranging the cables. The first connecting component further includes a first base, a plurality of first conductors, and a plurality of first latches. The first base has a first body, a plurality of first cable troughs, a plurality of first through holes, and a plurality of third cable troughs. The first body has a first surface and a third surface. The first and third cable troughs are formed in the first body to accommodate the cables. The first through holes extend through the first body with their central axes offset by a first angle from the first cable troughs, and one end of each of the first through holes is connected to the first cable troughs. The first and third cable troughs are recessed from at least one of the first and third surfaces. The first conductors are disposed in the first cable troughs. One end of the first conductors can be connected to one end of the cables, and the other end of the first conductors can be connected to the first terminals. First fasteners are disposed in at least one of the first cable troughs or the third cable troughs to secure the cables therein. A second connecting component can connect the first connecting component to a connectable circuit board via the cables, enabling at least one of signal and power transmission between the second connecting component and the circuit board.

[0013] To achieve the above and other objectives, the present invention provides a modular connector that transmits a signal and power between a light bar and a circuit board by connecting a plurality of cables. The light bar includes a plurality of first terminals, and the circuit board has a plurality of second terminals. A light source connection module includes a first connecting component and a second connecting component. The first connecting component is capable of connecting to the light bar and arranging the cables. The second connecting component is capable of connecting to the first connecting component and connecting to the circuit board through the cables. The second connecting component transmits at least one of a signal and power to the circuit board. The second connecting component further includes a second base and a plurality of second conductors. The second base includes a second body, a plurality of second cable troughs, a plurality of fourth cable troughs, and a plurality of second through holes. The second body includes a second surface and a fourth surface. The second body forms the second and fourth cable troughs for arranging the cables. The second through holes extend through the second body, with their central axes offset by a second angle from the second cable troughs. One end of each of the second through holes is connected to the second cable troughs. The second and fourth cable troughs are recessed from at least one of the second and fourth surfaces. The second conductors are disposed in the second cable troughs and the second through-holes. One end of each second conductor can be connected to the other end of the cables, and the other end of each second conductor can be connected to the second terminals. Second fasteners are disposed in at least one of the second or fourth cable troughs to secure the cables thereto.

[0145] Please refer to Figure 1(a) and 1(b) , are three-dimensional schematic diagrams of the modular connector connecting the light bar and the circuit board according to the first embodiment of the present invention from different viewing angles. Figure 1(a) is a front-view three-dimensional schematic diagram of the modular connector connecting the light bar and the circuit board according to the first embodiment of the present invention, and Figure 1(b) is a rear-view three-dimensional schematic diagram of the modular connector connecting the light bar and the circuit board according to the first embodiment of the present invention.

[0146] In FIG. 1( a ) and FIG. 1( b ), a modular connector 10 transmits a signal (not shown) and power (not shown) between a light bar 4 and a circuit board 6 by connecting a plurality of cables 2. Here, the number of cables 2 is four, and in other embodiments, the number of cables 2 is not limited. The light bar 4 includes a plurality of first terminals 22 (see FIG. 1 ). Figure 8 ) and the circuit board 6 have a plurality of second terminals 62 (refer to Figure 13 ).

[0147] The light source connection module 10 includes a first connection component 12 and a second connection component 14. Here, the light source connection module 10 is locked in the outer housing 8 having the opening 82 as an example.

[0148] For reference Figure 2 , is an exploded schematic diagram illustrating the first connecting component connecting cable of FIG1(a) and FIG1(b) of the present invention. Figure 2 In the embodiment, the first connecting component 12 can be used to connect the light bar 4 and the setting cable 2 in FIG. 1( a ) and FIG. 1( b ).

[0149] The first connecting assembly 12 further includes a first base 122 , a plurality of first conductors 124 and a plurality of first fastening members 126 .

[0150] The first base 122 includes a first body 1222, a plurality of first cable troughs 1224, a plurality of first through holes 1226, and a plurality of third cable troughs 1228. The first body 1222 forms the first cable troughs 1224 and the third cable troughs 1228 to accommodate the cables 2. The first cable troughs 1224 form a plurality of first clamping grooves 12242. The first clamping grooves 12242 can be formed on the edge of the first body 1222 or adjacent to the edge of the first body 1222.

[0151] The first through holes 1226 extend through the first body 1222, with their central axes at a first angle relative to the first cable troughs 1224. The first angle is 90 degrees. One end of the first through holes 1226 connects to the first cable troughs 1224. The first cable troughs 1224 and the first through holes 1226 form an L-shaped structure.

[0152] The first conductors 124 are disposed in the first cable ducts 1224 . One end of the first conductors 124 can be connected to one end of the cables 2 , and the other end of the first conductors 124 can be connected to the first terminals 22 .

[0153] The first fasteners 126 are disposed in the first clamping grooves 12242 to secure the cables 2 in the first cable grooves 1224. Here, the first fasteners 126 are illustrated as U-shaped metal pieces, and a protruding structure is formed at the inner edge of the first fasteners 126 to effectively clamp the cables 2.

[0154] The first connecting assembly 12 further includes a first cover 128 having a third body 1282. A plurality of fifth locking portions 12822 are formed around the periphery of the third body 1282. The first base 122 further includes a plurality of seventh locking portions 12210. The fifth locking portions 12822 are disposed corresponding to the seventh locking portions 12210.

[0155] The first connecting component 12 further includes a plurality of first locking portions 127 and a first buckling portion 129 (see FIG. 4( b ) or FIG. 5( c )). Figure 5 Here, the first locking portions 127 are formed on two sides of the exterior of the first body 122. For example, a plurality of first locking members 1272 are formed on the first locking portions 127 as a locking structure. For example, the first locking members 1272 are described as protrusions. In addition, the first fastening portion 129 is provided on the light bar 4. The first fastening portion 129 forms a plurality of first fastening members 1292 (see FIG. Figure 5 ) to correspond to the first locking members 1272. The first fastening members 1292 are combined with the first locking members 1272 to fix the first connecting component 12 to the light bar 4. Figure 3 , to illustrate the present invention Figure 2 . Furthermore, the first locking portions 127 and the first body 122 form a plurality of deformation spaces SP. The first locking portions 127 have a plurality of first pressing portions 1284. By applying an external force F, the first pressing portions 1284 change the shape of the deformation spaces SP, thereby disengaging the first locking members 1272 from the first fastening members 1292. It is worth noting that, for ease of mechanical assembly, a V-shaped clamping portion 1286 may be formed on the first locking portions 127. Furthermore, in another embodiment, a portion of the first pressing portions 1284 may be formed in the deformation spaces SP.

[0156] Back to Figure 2The first connecting component 12 and the cables 2 are assembled in such a manner that the cables 2 are first placed in the first cable troughs 1224 and the third cable troughs 1228.

In another embodiment, a stopper 12826 may be further included to secure the cables 2 in the first cable troughs 1224 . FIG4( b ) is also shown for illustrating the assembly diagram of the first cover combined with the first base, the first conductor, and the light bar of FIG4( a ) according to the present invention. Here, one end of the first conductors 124 forms a conductor clip 1242 to clamp the cables 2 and electrically connect to a conductor (not shown) located inside the conductors 2 . The conductor is, for example, a copper wire wrapped around the conductors 2 .

[0157] Returning to FIG. 1( a ), the aforementioned description includes, in addition to the first connecting component 12 not being located at the end of the module connector 10 , a first connecting component 13 located at the end of the module connector 10 . The first connecting component 13 provides for at least one of the cables 2 to be simultaneously disposed in the first cable troughs 1224 and the third cable troughs 1228 to form an electrical circuit, which may be referred to in conjunction with FIG.
