Connecting wire set and light source module connector thereof

Technical Field

The present utility model relates to a connection assembly of a backlight module, and more particularly, to a connection wire set and a light source module connector thereof.

Background

In general, in a backlight module for a display, a cable or a flat wire is used as a connection between a plurality of light source boards, so that an electrical signal and/or a power of a circuit board can be transmitted to a corresponding light source board, and then transmitted from each of the light source boards to a connected light bar. With the demand of thinning development of the display, the entire thickness of the backlight module is thinner and thinner, so that more display products adopt flat wires as connection modes. In addition, with the development of large-sized displays, the number of light source boards and light bars connected in series is increasing, the internal structure is more complex, and the connection reliability between electronic parts is also important.

In the existing flat wire connection mode, an insulating coating layer on the surface of a flat wire is directly perforated at a position corresponding to a contact point required by a board end seat on each light source board, so that an internal wire layer is exposed for being in contact with pin terminals of each light source board to achieve electric connection.

However, since the contact positions of different light source plates are different, the positions of the openings of the insulating coating layer on the surface of the flat wire should be corresponding one by one, so that the process is tedious and complex. With the development of large-sized displays, the number of light source plates connected in series on a flat line is increased, and the disadvantages of complex process and high cost are further deepened.

Fig. 1 is a schematic perspective view of a portion of a backlight module according to some embodiments of the utility model. The backlight module comprises a fixing plate 100, a plurality of plate ends 200, a flat wire 300, a plurality of light source module connectors 400 and a power plug-in module 500. The flat wire 300, the plurality of light source module connectors 400 and the power plug-in module 500 may form a connection line set for providing a connection interface for each lamp set (not shown, for example, a light source lamp strip) in the backlight module.

The mounting plate 100 is adapted to carry the plate ends 200. The respective board ends 200 are arranged at intervals, and both sides of each board end 200 are used to configure lamp groups (not shown, for example, light source lamp bars) correspondingly to form zoned light control on the left and right sides of the fixed board 100. And then, through independent control of each lamp group, the light control effect of more various subareas is achieved.

The flat wire 300 is coupled to the power socket by plugging the power plug module 500 into the power socket (located below the power plug module 500 in fig. 1), and is used for transmitting power signals to the board terminals 200 through the flat wire 300 and the light source module connector 400, and then to the lamp groups. Wherein, each light source module connector 400 provides an electrical connection interface between the flat wire 300 and the corresponding board end 200, and stable and low-cost electrical connection can be achieved through the configuration and arrangement of the light source module connectors 400.

Referring to fig. 2, 3 and 4, fig. 2 is an exploded view of a light source module connector coupled to a board end socket according to some embodiments of the present utility model, fig. 3 is another perspective view of a channel selection module coupled to a flat wire according to some embodiments of the present utility model, and fig. 4 is a perspective view of a second terminal of the channel selection module according to some embodiments of the present utility model. Fig. 2 and 3 show different views of the two figures in directions X, Y and Z.

The board end 200 is provided with a board end socket 210 and a plurality of first terminals 211 coupled to the board end 200 and penetrating the board end socket 210. The light source module connector 400 includes: the first cover 410, the second cover 420 and the channel selection module 430. The first cover 410 includes a window 411 for a portion of the channel selection module 430 to protrude. The first cover 410 may be combined with the second cover 420 (e.g., coupled to the plurality of fastening slots 422 of the second cover 420 through the plurality of fasteners 412 of the first cover 410) so that the flat wire 300 and the channel selection module 430 are fixed therein.

The channel selection module 430 includes a base 431 and a plurality of second terminals 432. The base 431 has a fixing portion 4311 and a socket portion 4312. The second terminal 432 has a fixed section 4321 and a contact section 4322. The protruding plug 4312 is configured to plug into the slot 212 of the board end socket 210. On the opposite surfaces of the insertion portion 4312, a closed region B and an open region O are defined by the arrangement of the insertion portion 4312 on the material distribution (through the mold). That is, the area of the plugging portion 4312 covered (shielded) by the contact section 4322 of the second terminal 432 is referred to as a closed area B, and the area of the plugging portion 4312 exposing (not shielded) the contact section 4322 of the second terminal 432 is referred to as an open area O.

Wherein the fixed sections 4321 of the second terminals 432 are coupled to corresponding channels of the flat wire 300 one-to-one. For example, the fixing sections 4321 of the second terminals 432 can be mounted on the corresponding channels of the flat wire 300 by a process such as a low-temperature surface-mount technology (Surface mount techno logy, SMT). In addition, the fixing section 4321 of each second terminal 432 may be configured to protrude from the bottom of the fixing portion 4311 (as shown in fig. 2 and 3), so as to further facilitate the installation between the channel selection module 430 and the flat wire 300 in the SMT process.

Because the corresponding channels of the lamp groups to be coupled are different, the configuration mode can respond to the change of the contact point through the change of shielding or not. The plug 4312, which is a material piece covering the contact section 4322 of the second terminal 432, can form a shielding without connecting channels; on the other hand, the connecting passage, the insertion portion 4312, having the opening exposing the contact section 4322 of the second terminal 432, is formed without shielding. The contact section 4322 of the second terminal 432, which is located in the open area O, provides coupling of the corresponding first terminal 211 on the board end socket 210.

The insertion parts 4312 can be easily formed by adjusting the mold parts at the corresponding positions on the mold during forming, and the respective seat bodies 431 having the combination of the different open areas O and the different closed areas B can be manufactured.

Referring next to fig. 5, a schematic perspective view of a portion of a connection wire set coupled to a board end in a bottom view according to some embodiments of the utility model is shown. The first group of light source module connectors 400a are mounted with a first group of channel selection modules 430a, and the first group of channel selection modules 430a are configured with a combination of open areas O1. The second group of light source module connectors 400b are mounted with a second group of channel selection modules 430b, and the second group of channel selection modules 430b are configured with a combination of open areas O2. Therefore, each light source module connector can lead the corresponding channel in the flat wire 300 to the mounted board end socket, so that the control end can control the corresponding light bar through the selection of the channel to achieve the zonal light control effect, and meanwhile, the light source module connector can also establish quite stable electric connection characteristics with the flat wire.

Next, referring to fig. 6, a schematic partial cross-sectional view of a light source module connector according to some embodiments of the utility model at a first terminal position when plugged into a board-end socket.

The first terminal 211 of the board-end socket 210 is bent to form a turn portion 2111 and protrudes from the groove wall of the slot 212 of the board-end socket 210. The side surface of the plugging portion 4312 of the channel selection module 400 is provided to abut against the turning portion 2111 of the first terminal 211, and the corresponding first terminal 211 is contacted with the second terminal 432 in the opening area O (please refer to fig. 3).

After the socket 4312 is positioned in the slot 212, a contact point T between the turning portion 2111 and the second terminal 432 is spaced apart from an end of the contact section 4322 of the second terminal 432 by a effective distance D. The effective distance D is not less than 0.8 (mm). Further, this effective distance may be configured to be about 1.05 (mm).

Referring to fig. 7 and fig. 8, fig. 7 is a schematic cross-sectional view of another part of the light source module connector at the first terminal position when plugged into the board-end socket according to some embodiments of the present utility model, and fig. 8 is a schematic perspective view of the first cover body coupled to the board end according to some embodiments of the present utility model.

The first cover 410 includes a body 413, a first cantilever 414, and a second cantilever 415. The first cantilever 414 and the second cantilever 415 are respectively disposed at two opposite sides of the body 413 and can move toward the body 413 when being stressed. That is, there is a gap between the first cantilever 414 and the body 413, and a gap between the second cantilever 415 and the body 413, so that when a force is applied to the first cantilever 414 and the second cantilever 415, the first cantilever 414 and the second cantilever 415 deform and move. The first cantilever 414 and the second cantilever 415 have a protrusion 416 at a middle position thereof, and the two sides of the board end socket 210 have a buckle piece 213, respectively, and each buckle piece 213 has a buckle hole 2131. As shown in fig. 7, the protruding blocks 416 are disposed on the corresponding first cantilever 414 or the second cantilever 415, and face the corresponding buckling piece 213 on one side outwards, and after the plugging portion 4132 is plugged into the board end socket 210, each protruding block 416 is used to be buckled into each corresponding buckling hole 2131 of the board end socket 210.

As an example, the first cantilever 414 and the second cantilever 415 may further have pressing portions 417, respectively, each pressing portion 417 is a n-shaped structure formed at a middle position of the first cantilever 414 and the second cantilever 415, and the bump 416 on the corresponding side may be accommodated in the pressing portion 417. After the first cover 410 is assembled to the board end socket 210, the corresponding buckle piece 213 protrudes into the inverted U-shaped structure to be buckled with the corresponding bump 416. The pressing portion 417 disposed at the intermediate position of the first cantilever 414 and the second cantilever 415 can provide a larger deformation amount when being pressed. When the user applies force to press the pressing portion 417 of the first cantilever 414 and the second cantilever 415, the first cantilever 414 and the second cantilever 415 deform to move in the direction of the body 413, so that the distance between the two protrusions 416 is smaller than the distance between the two tabs 213, and the assembly or disassembly operation can be performed.

The first cantilever 414 and the second cantilever 415 have downward protruding stoppers 418 at the middle positions thereof, and the two sides of the board end socket 210 have stopper rails 214, respectively, and after the first cover 410 is assembled to the board end socket 210, each stopper 418 is configured to be received in each stopper rail 214 corresponding to the board end socket 210, so that the first cover 410 is limited in the direction Y, thereby improving the reliability of assembly and avoiding the skew. In addition, when the pressing is applied externally, the pressing stroke is stabilized by the restriction of the limit rail 214, and no deflection occurs.

Next, referring to fig. 9, a schematic cross-sectional view of a connection wire set, a board end and a power supply base according to some embodiments of the utility model is shown.

The light source module connector 400 plugged with the corresponding board end 200 provides selective coupling to the electrical connection channel between the flat wire 300 and the board end 200 by the differentiated definition of the enclosed area and the open area. After each light source module connector 400 is plugged into the corresponding board end 200 (e.g., plugged into the board end socket 210 shown in fig. 2), the top surface of the power plug module 500 is the same height as the top surface of the light source module connector 400, and the overall height is the same. Accordingly, the light generated by the lamp sets (not shown, for example, the light source lamp bars) disposed correspondingly on both sides of the board end 200 is not partially shielded by the power plug module 500, and thus no shadow is generated on the display screen.

In summary, the configuration and arrangement of the closed area and the open area of the channel selection module of the light source module connector can define which channels can be coupled with the corresponding board end sockets, so that the complexity of the manufacturing process can be effectively reduced, the manufacturing cost can be reduced, and the high stability of electrical connection can be achieved. Furthermore, the lateral abutting coupling mode is adopted between the terminal of the board end and the terminal of the light source module connector, so that the conventional risk of the vertical abutting of the board end is eliminated. The arrangement of some configurations on the mechanism also allows the use of the integral member to be further enhanced in reliability. Therefore, in the use of the whole connecting wire set and the light source module connector thereof, the excellent characteristics of reducing the manufacturing cost and considering the stability of the electric connection are more highlighted.

While the utility model has been disclosed in terms of preferred embodiments, it will be understood by those skilled in the art that the embodiments are merely illustrative of the utility model and should not be construed as limiting the scope of the utility model. It should be noted that all changes and substitutions equivalent to those of the embodiments are intended to be included in the scope of the present utility model.
