Abstract

The utility model provides a prevent short circuit FPC circuit board, which comprises a substrate, the base plate is equipped with the copper foil of two isolations, be equipped with the locating hole on the base plate, the locating hole both sides are equipped with the holding ring that is minor arc shape, be equipped with the isolation groove between the holding ring. The isolation groove is used for isolating the positioning ring, even if the positioning ring on one side of the substrate is communicated with the copper foil, the two positioning rings cannot be communicated with each other, and therefore the problem that the FPC circuit board is easy to short circuit is solved.

Description

Short-circuit-proof FPC circuit board

Technical Field

The utility model relates to a FPC circuit board technical field specifically is a prevent short circuit FPC circuit board.

Background

The FPC board, also called flexible circuit board, is a flexible printed circuit board with high reliability and excellent performance, which is made of polyimide or polyester film as base material. The high-density light-weight LED lamp has the characteristics of high wiring density, light weight, thin thickness and good bending property.

The FPC board is generally provided with positioning holes to facilitate mounting. In order to improve the strength of the positioning hole and avoid tearing the circuit board, a positioning ring is generally arranged outside the positioning hole. Because the clearance between the positioning ring and the copper foil is smaller, the positioning ring is easily communicated with the copper foil during etching, and therefore the two copper foils are communicated to generate short circuit.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the technical problem that short circuit is easy to occur when a positioning ring and copper foil in a traditional FPC circuit board are etched is solved.

The utility model provides a prevent short circuit FPC circuit board, which comprises a substrate, the base plate is equipped with the copper foil of two isolations, be equipped with the locating hole on the base plate, the locating hole both sides are equipped with the holding ring that is minor arc shape, be equipped with the isolation groove between the holding ring.

The isolation groove is used for isolating the positioning ring, even if the positioning ring on one side of the substrate is communicated with the copper foil, the two positioning rings cannot be communicated with each other, and therefore the problem that the FPC circuit board is easy to short circuit is solved.

Further, the isolation groove is communicated with the positioning hole. So set up, not only increased the isolation scope of holding ring, the holding ring is difficult for the intercommunication more, but also the locating hole installation of being convenient for.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a front view of the present invention;

FIG. 2 is an enlarged view at A in FIG. 1;

in the figure: 1. a substrate; 2. copper foil; 3. positioning holes; 4. a positioning ring; 5. and (4) isolating the groove.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

As shown in fig. 1, the utility model relates to a short-circuit-proof FPC circuit board, which comprises a substrate 1, wherein the substrate 1 is provided with two isolated copper foils 2, a positioning hole 3 is arranged on the substrate 1, and positioning rings 4 in the shape of inferior arcs are arranged at two sides of the positioning hole 3;

as shown in figure 2, the isolation groove 5 for communicating the positioning holes 3 is arranged between the positioning rings 4, so that the isolation range of the positioning rings 4 is enlarged, the positioning rings 4 are not easy to communicate, and the positioning holes 3 are convenient to install.

The isolation groove 5 is used for isolating the positioning rings 4, even if the positioning rings 4 on one side of the substrate 1 are communicated with the copper foil 2, the two positioning rings 4 cannot be communicated with each other, and therefore the problem that the FPC circuit board is easy to short circuit is solved.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
