Description

Technical Field

[0001] The utility model relates to the field of circuit boards, in particular to a ceramic circuit board with strong practicality. Background Art

[0002] Circuit board, also known as printed circuit board, is a substrate used to support and connect electronic components. The surface is covered with a conductive layer for arranging and connecting electronic components to form a circuit. With the development of technology, circuit boards are more highly integrated. Ceramics are used as circuit board materials because of their good heat dissipation. Ceramic circuit boards have the advantages of high thermal conductivity, excellent chemical stability and thermal stability.

[0003] However, ceramics are brittle and easily broken by external forces. Circuit boards are mostly installed in the body with bolts. During the use of the equipment, it is inevitable that bumps will occur. The force of the collision is transmitted to the ceramic circuit board, which can easily cause cracks. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1 , Figure 2 and Figure 4A ceramic circuit board with strong practicality includes a ceramic board 1. The upper surface of the four corners of the ceramic board 1 is provided with through holes 4. The specific structure and working principle of the ceramic board 1 are the existing technology well known to the staff in this field, and no further elaboration is made here. A vertical rod 7 is arranged inside the through hole 4. Rubber pads 6 are arranged at both ends of the vertical rod 7. The two rubber pads 6 are respectively abutted against the upper and lower sides of the ceramic board 1. A top cover 2 is arranged on the upper surface of the upper rubber pad 6. A round rod 9 is fixedly connected to the lower surface of the top cover 2. A screw rod 8 is fixedly connected to the lower surface of the round rod 9. The round rod 9 passes through the rubber pad 6 and the vertical rod 7. The round rod 9 is movably connected to the rubber pad 6 and the vertical rod 7. The installation can be completed by aligning the screw 8 with the position to be installed and rotating the top cover 2. A circular ring 10 is fixedly connected to the outer surface of the round rod 9, and the upper surface of the circular ring 10 abuts against the lower surface of the lower rubber pad 6, which has a limiting effect on the round rod 9. A limiting block 5 is arranged on the inner wall of the through hole 4, and the limiting block 5 abuts against the outer surface of the vertical rod 7. The cross-section of the rubber pad 6 is trapezoidal, and the two rubber pads 6 are symmetrically arranged with the vertical rod 7. The diameter of the through hole 4 is half of the sum of the diameters of the two bottom surfaces of the rubber pad 6. The limiting block 5 on the inner wall of the through hole 4 will abut against the outer surface of the vertical rod 7, so that the ceramic plate 1 and the device are flexibly connected, and the ceramic plate 1 can undergo a small displacement and tilt, which can play a buffering role when the ceramic plate 1 is subjected to a collision force, thereby achieving the effect of protecting the ceramic plate 1. The versatility of the device can improve its applicability.

[0022] Reference Figure 1 , Figure 2 and Figure 3 The outer surface of the ceramic plate 1 is provided with a card slot 3, and the card slot 3 is arranged at both ends of the ceramic plate 1 and there are four of them. The size of the vertical rod 7 is the same as the size of the card slot 3. When the ceramic plate 1 is transported, the vertical rod 7 is connected to the inside of the card slot 3, and the vertical rod 7 is sunk into the card slot 3. The rubber pads 6 on the upper and lower sides of the vertical rod 7 will abut against the inner wall of the packaging board, which can play a buffering and shock-absorbing effect when a collision occurs during transportation, thereby ensuring stability and safety during transportation.

[0023] The specific working principle of the utility model is as follows: through holes 4 are opened on the upper surface of the four corners of the ceramic plate 1, and a card slot 3 is set on the outer surface of the ceramic plate 1. When the ceramic plate 1 is transported, the vertical rod 7 is clamped in the inside of the card slot 3, and the vertical rod 7 is sunk into the card slot 3. The rubber pads 6 on the upper and lower sides of the vertical rod 7 will abut against the inner wall of the packaging board, which can play a buffering and shock-absorbing effect when a collision occurs during transportation, ensuring stability and safety during transportation. When the user installs the ceramic plate 1, the vertical rod 7 is taken out of the card slot 3 and inserted into the through hole 4. Due to the rubber pads 6, the vertical rod 7 can be easily inserted into the through hole 4. The pad 6 is made of soft material and can be squeezed and passed through the through hole 4. The screw 8 is aligned with the position to be installed and the top cover 2 is rotated. After the ceramic plate 1 is installed, the two rubber pads 6 are respectively abutted against the upper and lower sides of the ceramic plate 1. At the same time, the limit block 5 on the inner wall of the through hole 4 will abut against the outer surface of the vertical rod 7, so that the ceramic plate 1 and the device are flexibly connected. The ceramic plate 1 can undergo a small displacement and tilt, which can play a buffering role when the ceramic plate 1 is subjected to a collision force, thereby achieving the effect of protecting the ceramic plate 1. The versatility of the device can improve its applicability.
