The quantity of first capture pad is two, and the quantity of second capture pad is two.Due in two flexible circuits
A pad is respectively set on plate can only be such that position at the one of two flexible circuit boards welds, and connection is not firm enough, and when welding
Contraposition is also not accurate enough, and too many pad is respectively set on two flexible circuit boards makes two flexible circuit boards connections make structure
Increase with the complexity of technique.By the way that two pads, two flexible circuit board connections are respectively set on two flexible circuit boards
Contraposition is cried accurate when firm, welding, and the structure of two flexible circuit boards and technique are also relatively simply.
In order to detect the first flexible circuit board and the second flexible circuit board, whether grafting is good, wherein one embodiment
In, as shown in figure 3, two the first capture pad electrical connections.In another embodiment, two first capture pads
Electrical connection.By by two the second tack weldings of two the first capture pads of the first flexible circuit board or the second flexible circuit board
Disk is electrically connected, and can confirm whether two pads are welded in place, to examine by the resistance between two pads of detection
Surveying the first flexible circuit board and the second flexible circuit board, whether grafting is good.
It is noted that if the interface quantity of flexible circuit board is excessive and structure space is insufficient, usually using connection
Device makes two flexible circuit board connections.In one of the embodiments, as shown in Fig. 5, Fig. 6 and Fig. 7, flexible circuit board connection knot
Structure further includes connector 300, and the connector 300 is arranged in first flexible circuit board 100 and second flexible circuit
Between plate 200, the connector 300 is electrical with first flexible circuit board 100 and second flexible circuit board 200 respectively
Connection.
Specifically, electrical connection, while connector are realized by the probe contacted between connector and flexible circuit board
So that two flexible circuit boards is achieved a fixed connection indirectly, but only passes through connector and flexible circuit between two flexible circuit boards
The probe contacted on plate achieves a fixed connection indirectly, when flexible circuit board, which exists, to be bent, can have pulling force and make flexible circuit
Plate is easy to detach inside connector, so that two flexible circuit boards disconnect.By in the first flexible positioning
It is provided at least one first capture pad on plate, is provided at least one second capture pad on the second flexible positioning plate,
And weld together the first capture pad and the second capture pad one-to-one correspondence, make the first flexible circuit board and the second flexible electrical
Plate realization in road is bonded, and is avoided flexible circuit board and is easy to detach inside connector, so that two flexible electricals
Road plate disconnects, and can be fixed by the first capture pad and second when the first flexible circuit board and the connection of the second flexible circuit board
Position pad positioning, it is no longer necessary to using positioning silk-screen line, simplify structure.
Further, as shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7, two opposite surfaces of the connector 300 are set respectively
It is equipped with the first pad structure 310 and the second pad structure (not shown), first golden finger structure 120 and first pad
Structure 310 is electrically connected, and second golden finger structure 220 and second pad structure are electrically connected.
Specifically, first pad structure 310 includes multiple first pads, second pad structure includes multiple the
Two pads, the first golden finger structure 120 include multiple first golden fingers, and the second golden finger structure 220 includes multiple second gold medal hands
Refer to, each first golden finger is electrically connected with each first pad correspondingly, and each second golden finger one is a pair of
It is electrically connected with each second pad with answering.
The connection of first flexible circuit board and the second flexible circuit board for convenience, it is described in one of the embodiments,
The quantity of first capture pad is two, and the quantity of second capture pad is two, and two first capture pads are equal
Positioned at the same side of first golden finger structure, two second capture pads are respectively positioned on second golden finger structure
The same side.Due to being provided with connector between the first flexible circuit board and the second flexible circuit board, by the first capture pad and
The same side of golden finger structure is arranged in two capture pads, namely positioned at the same side of connector, avoids for connector being wrapped in
Between pad, it is more convenient replacement connector.
It is relatively firm in order to connect the first flexible circuit board and the second flexible circuit board with connector, a reality wherein
It applies in example, for first capture pad adjacent to one end of first golden finger structure, another first capture pad is adjacent
The other end of nearly first golden finger structure.By the way that two capture pads are arranged, and two capture pads are set at both ends,
The both ends of connector are located at, first flexible circuit board, the second flexible circuit board in region and company between two pads are made
It is relatively firm to connect device connection.
In order to prevent the first flexible circuit board and the second flexible circuit board connection error, avoid anti-inserted a, reality wherein
Apply in example, two first capture pads and first flexible circuit board adjacent to the side of first capture pad away from
From different setting.By the way that two the first capture pads are used asymmetric setting, the first flexible circuit board and the second flexibility are prevented
Circuit board incorrect link avoids anti-inserted, better fool proof and reduction device failure risk.
In order to keep the first contraposition pad and the second contraposition pad bonding area larger so that the first flexible circuit board and
The connection of second flexible circuit board is more firm, in one of the embodiments, first contraposition pad and second contraposition
Bond pad shapes are identical.By keeping the first contraposition pad identical as the second contraposition pad shape, make the first contraposition pad and second pair
Position pad solder area is larger, so that the first flexible circuit board and the connection of the second flexible circuit board are more firm.
