In the technical scheme, the utility model discloses when testing flexible circuit board, flexible circuit board takes place crooked state when the crooked emulation of usable insulating tube falls to can overcome among the prior art the problem that can't measure the rosin joint state when testing on the plane, the rosin joint phenomenon of inspection product that can be more accurate plays the interception and prevents the circulation.
Drawings
Fig. 1 schematically shows a schematic structural diagram of the present invention.
Reference numbers in the figures: 1. a base plate; 2. an insulating tube; 3. a backplane electrode; 4, tube electrode; 5. and (4) conducting wires.
Detailed Description
The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.
The utility model discloses an aspect provides a tool is lighted to cell-phone screen flexible circuit board arc, include: the anti-static electricity-proof base plate comprises a base plate 1, an insulating tube 2 (used for preventing static electricity), a base plate electrode 3, a tube body electrode 4 and a wire 5, wherein the insulating tube is installed on the base plate 1, the base plate electrode 3 is installed on the base plate 1, a through hole is formed in the tube wall of the insulating tube 2, the tube body electrode 4 is installed in the through hole, and the base plate electrode 3 is electrically connected with the tube body electrode 4 through the wire 5. Preferably, the insulating tube 2 is a PVC tube. Preferably, a portion of the wire 5 is disposed in the insulating tube 2. Preferably, the diameter of the insulating tube 2 is 8-15cm, and the bottom plate 1 can be made of red iron wood.
When the flexible circuit board is used, an external power supply is connected to the bottom plate electrode 3, the flexible circuit board to be tested to be lightened leans against the insulating tube 2 in a bending mode, the tube body electrode 4 on the insulating tube 2 is in contact with the power supply pin on the flexible circuit board, and therefore power is supplied to the flexible circuit board, and the LED lamp on the flexible circuit board is lightened.
In the technical scheme, the utility model discloses when testing flexible circuit board, flexible circuit board takes place crooked state when the crooked emulation of usable insulating tube 2 falls to can overcome among the prior art the problem that can't measure the rosin joint state when testing on the plane, the rosin joint phenomenon of inspection product that can be more accurate plays the interception and prevents the circulation.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
