Description
Technical field
The utility model relates to a kind of LED-backlit module.
Background technology
In recent years due to the continuous progress of LED technology, LED has become the main alternative of light source of middle large scale liquid crystal backlight sources of display device, LED is as the light source source of backlight source of liquid crystal display apparatus, in middle large scale, its arrangement is in the one or both sides of liquid crystal module back light source module group unit and more than both sides arranges the LED of some, or in large scale, is arranged to straight-down negative.
LED lamp bar is that LED groups of grains is contained in to PCB substrate (preferably a kind of hard circuit substrate) above or banded FPC(flexible PCB) on, especially be assembled in the LED lamp bar on PCB substrate, can apply in backlight module, LCD TV size is done larger and larger now, but due to production equipment, the restriction of the conditions such as technique, single LED lamp bar can not accomplish to grow very much (reaching and large scale TV requirement length specification), therefore, two or more LED lamp bar can be stitched together to reach length requirement, common technology generally has following several connected mode: 1, directly by wire bonds, 2, LED lamp bar welds respectively socket with wire and is connected, 3, the male and female connector cooperatively interacting in the welding of lamp bar two ends, then two LED lamp strip connectors are pegged graft, and realize conduction and connect.
By the meaning that wire directly welds, be that two wires are welded mutually with the positive and negative electrode of LED lamp bar respectively, realize the conduction UNICOM of two LED lamp bars.The defect of this connected mode is: welding is usually used in test or manual sample has a fling at, complicated operation, and efficiency is very low, is difficult to use in batch production.
Figure 1 shows that the structural representation of existing LED lamp bar and wire, suppose and have two LED lamp bars to weld: be defined as respectively a LED lamp bar 110 and the second lamp bar 120, one end that the one LED lamp bar 110 is relative with the 2nd LED lamp bar 120 is provided with two first mother socket 111,112, the two LED lamp bars 120 one end relative with a LED lamp bar 110 and is also provided with two the second mother sockets 121,122.
Two wires are provided, and the two ends that the two ends that are defined as respectively the first wire 130 and the second wire 140, the first wires 130 are equipped with the first male plug 131,132, the second wires 140 are equipped with the second male plug 141,142.
During installation, as shown in Figure 2, the first male plug 131,132 of the first wire 130 is arranged on respectively on the first mother socket 111 of a LED lamp bar 110 and the second mother socket 121 of the 2nd LED lamp bar 120, the second male plug 141,142 of the second wire 140 is arranged on respectively on the first mother socket 111 of a LED lamp bar 110 and the second mother socket 121 of the 2nd LED lamp bar 120, by male plug and mother socket, join, the conduction that realizes two LED lamp bars connects.
But the defect of this LED connected mode is: socket need to be welded respectively in wire and LED lamp bar two ends, and cost is higher, and wire socket need to be plugged on lamp bar socket when producing, and due to socket small volume, it is very inconvenient to operate, and production efficiency is very low.
The connected mode that the Male/female connector that the welding of lamp bar two ends cooperatively interacts is pegged graft, as shown in Figure 3, in LED lamp bar 210 ends, weld the first socket 211, in the 2nd LED lamp bar 220 ends, also weld the second socket 221, wherein, the first socket 211 is male plug, and the second socket 221 is that mother socket or the first socket 211 are mother socket, and the second socket 221 is male plug.The conduction that realizes two LED lamp bars by first, second socket 211,221 is connected connects.But the shortcomings and deficiencies of this connected mode are: when LED lamp strip unit enters module, require the fit tolerance of male and female socket very little, because LED lamp bar end may perk, or lamp bar is when be distorted, and male and female socket has very large stress and exists after may not connecting or connect, produce potential safety hazard, if loose contact or damage appear in socket in addition, whole lamp bar can become defective products, can have influence on the use of whole lamp bar, cause the waste of resource, the increase of cost.
Therefore need to design a kind of new LED lamp strip connector.
