Abstract

The utility model discloses a printing ink plug copper block inlaying structure which comprises a double-sided board, a copper block groove is formed in the double-sided board, a copper block is placed in the copper block groove, each edge of the inner side of the copper block groove is provided with an anti-skid salient point which is integrally formed, and a plurality of anti-skid salient points are matched to limit the copper block to be centered in the copper block groove. Therefore, the copper blocks are not in contact with the inner sides of the copper block grooves all the time, and gaps exist between the front ends of the anti-skid protruding points and the copper blocks. According to the copper block inlaying structure for the ink plug, the copper block can be limited from deviating in the copper block groove, it is guaranteed that ink can be smoothly fed around the copper block when resin is used for hole plugging, and poor product quality is avoided.

Description

Technical Field

[0001] The utility model relates to an ink plug copper block inlay structure, belonging to the technical field of double-sided board embedded copper products. Background Art

[0002] like Figure 2 As shown in the figure, in the double-sided board embedded copper process, since the double-sided board is not pressed, the copper block needs to be embedded in the double-sided board by plugging the holes with resin ink. Figure 3 As shown, since the copper block slot for placing the copper block is consistent with the shape of the copper block, in order to ensure that the copper block slot can hold the copper block, the copper block slot is designed to be larger than the copper block, causing the copper block to slide and deviate in the copper block slot, or even completely lean against the side, resulting in plugging gaps without resin ink, resulting in poor product quality. Summary of the invention

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide an ink plug copper block inlay structure, which can limit the deviation of the copper block in the copper block groove, ensure that oil can be smoothly poured around the copper block when the resin plugs the hole, and avoid poor product quality.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] An ink plug copper block inlay structure comprises a double-sided board, a copper block groove is opened in the double-sided board, a copper block is placed in the copper block groove, each side of the inner side of the copper block groove is provided with an integrally formed anti-skid protrusion, a plurality of the anti-skid protrusions cooperate to limit the copper block to be centered in the copper block groove so that the copper block is always not in contact with the inner side of the copper block groove, and there is a gap between the front end of the anti-skid protrusion and the copper block.

[0006] The copper block groove is in the shape of a rounded rectangle.

[0007] The top shape of the anti-slip convex point is an acute angle.

[0008] The number of the anti-slip protrusions on each side of the copper block groove is two.

[0009] The size of the gap is 0.08-0.12 mm.

[0010] The size of the gap is 0.1 mm.

[0011] Beneficial effects of the utility model: The utility model provides an ink plug copper block inlay structure, which reduces the sliding deviation of the copper block in the copper block groove by adding an anti-slip convex dot design at the copper block groove where the copper block is placed, thereby improving the quality risk of ink connection gap caused by poor sliding inclination of the copper block when the ink is plugged. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The reference numerals in the figure are as follows: 1-double-sided board; 2-copper block groove; 3-anti-slip bump; 4-copper block. DETAILED DESCRIPTION

[0016] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are not intended to limit the protection scope of the present invention.

[0017] like Figure 1 As shown, the utility model discloses an ink plug copper block inlay structure, comprising a double-sided board 1, a copper block groove 2 is opened in the double-sided board 1, the copper block groove 2 is in the shape of a rounded rectangle, and a copper block 4 is placed in the copper block groove 2.

[0018] The improvement of the utility model is that an integrally formed anti-skid protrusion 3 is provided on each side of the inner side of the copper block groove 2, and the top shape of the anti-skid protrusion 3 is an acute angle. There are two anti-skid protrusions 3 on each side of the copper block groove 2. A total of 8 anti-skid protrusions 3 cooperate to limit the copper block 4 to be centered in the copper block groove 2, so that the copper block 4 does not contact the inner side of the copper block groove 2 at all times.

[0019] There is a gap between the front end of the anti-slip bump 3 and the copper block 4. The size of the gap between the front end of the anti-slip bump 3 and the copper block 4 is 0.08~0.12mm, and in this embodiment, the size of the gap is preferably 0.1mm. The 0.1mm gap design value of the utility model can ensure that when the bump is formed and fished out, there is a margin to plug the copper block, preventing the bump tolerance from causing the copper block to be unable to be inserted into the copper block slot. At the same time, the distance of 0.1mm is small enough to allow the copper block to slide in the copper block slot. The offset is less than 0.1mm.

[0020] The utility model provides an ink plug copper block inlay structure, which adds anti-skid protrusions around the copper block groove to center the copper block and maintain a minimum gap of less than 0.1mm with the surrounding double-sided panels, which can not only ensure that the copper block does not deviate, but also ensure that oil can be smoothly applied around the copper block when the resin is plugged, and ensure that there is no gap between the copper block and the surrounding areas after oil is applied, thereby ensuring the quality of the resin plugging hole and the quality of the PCB product.

[0021] The above are only preferred implementations of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
