Embodiment 1

[0028] refer to figure 1 , the FFC (Flexible Flat Cable, flexible flat cable) connector of the present invention includes: a base 11, an upper cover 12, a shrapnel 13 and a positioning piece 14, wherein the base 11 is used to be fixed on the light bar assembly, and the upper cover 12 is rotatable Hinged on the base 11, the shrapnel 13 is mainly used to conduct the external power supply and the light bar assembly. The shrapnel 13 is set on the base 11 and the top of the shrapnel 13 protrudes from the upper surface of the base 11, and the bottom end of the shrapnel 13 protrudes from the base. 11 The lower surface is electrically connected to the light bar assembly. The top of the shrapnel 13 is higher than the upper surface of the base 11, and the surface of the FFC cable 40 opposite to the shrapnel 13 is provided with a conductive terminal in electrical contact with the shrapnel 13, which plays a conductive role and can also connect the FFC row placed on the base 11. The wire ...

Embodiment 2

[0034] Such as figure 2 and image 3 As shown, the direct-lit backlight module of the embodiment of the present invention includes a rear case 20, a plurality of parallel and spaced light bar assemblies 30, FFC cables 40 and FFC connectors 10, and the light bar assemblies 30 are fixedly arranged on the rear case 20. Inside, each light bar assembly 30 is correspondingly provided with an FFC connector 10 . The FFC cable 40 is sandwiched between the base 11 and the upper cover 12 of the FFC connector 10, combined Figure 4 , the FFC cable 40 is provided with a conductive terminal 42 electrically connected to the elastic piece 13 , and the bottom end of the elastic piece 13 is electrically connected to the light bar assembly 30 .

[0035] The light bar assembly 30 includes a substrate 31 , an LED light bead 32 and a lens 33 . A notch 41 is formed in the width direction of the FFC cable 40 , and a positioning member 14 protrudes from the upper surface of the base 11 , and the p...

Embodiment 3

[0040] Such as Figure 4 and Figure 5 The FFC cable 40 includes a notch 41, a conductive terminal 42, a plug terminal 43, an adhesive part 44, and a release film 45. The plug terminal 43 is located at both ends of the FFC cable 40 in the length direction, and the conductive terminal 42 is located at multiple Between the plug terminals 43 , each of the conductive terminals 42 and the plug terminals 43 includes a plurality of contacts to ensure reliable contact with the light bar assembly 30 . After the release film 45 is peeled off, roll the winding wheel 100, and the elastic buffer shaft 102 elastically presses the rolling wheel 101 under the action of an external force, thereby pressing the FFC cable 40, and using the sticking part 44 to stick the FFC cable 40 on the rear case 20 and on the base 11 of the corresponding FFC connector 10 .

[0041] The wiring device of the embodiment of the present invention can be applied to the direct type backlight module of the second em...

Abstract

The invention discloses an FFC (flexible flat cable) connector comprising a base, an upper cover, at least one spring and a positioner. The upper cover is rotatably hinged to the base. The springs are disposed on the base; the top ends of the springs protrude from the upper surface of the base; the bottom ends of the springs extend out of the lower surface of the base. The positioner protrudes from the upper surface of the base. The free end of the upper cover is provided with an extension part bent; the extension part is used for being fastened to the base. The invention further discloses a backlight module and a wiring device. The FFC connector allows an FFC to be well fixed and allows the FFC and a light bar component to be reliably and electrically connected; after the plug end of the FFC is electrified, the FFC can be electrically connected with various light bar components through the FFC connectors; a wiring mode is simple, fixing is reliable, FFC wiring difficulty is greatly decreased, and assembly efficiency of the backlight module is greatly improved; meanwhile, the wiring mode is higher in automation level, and a wiring process is greatly simplified.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an FFC connector, a direct-type backlight module and a wiring device. Background technique [0002] Common backlight modules are mainly divided into two types: direct-lit and side-illuminated. Direct-lit backlight modules generally do not require a light guide plate, so they are more cost-effective than side-lit. Application of domain control light technology. [0003] Generally, the LED (Lighting Emitting Diode, Light Emitting Diode) lamp beads of the direct-lit backlight module are evenly distributed on the back cover, which is divided into multiple blocks by the circuit, so more connecting wires are needed to connect the LED light bar to the whole Compared with the side-entry backlight module, the connection method of connecting wires is more complicated, the connection process is more cumbersome, and the assembly efficiency is lower.
