The present invention is described in detail below in conjunction with the drawings.

[0021] Example 1

[0022] A wear-resistant circuit board, such as Figure 1 to Figure 2 As shown, it includes a circuit board body 1 and an anti-wear component; the anti-wear component includes two anti-wear blocks 2 arranged opposite to each other, the two anti-wear blocks 2 are symmetrically arranged about the circuit board body 1, and a mounting groove 3 is arranged on the side opposite to each other of the two anti-wear blocks 2, and an upper anti-wear rubber strip 4 and a lower anti-wear rubber strip 5 are respectively arranged on the upper end surface of the inner wall of the mounting groove 3 and the lower end surface of the inner wall of the mounting groove 3; the upper end surface of the inner wall of the mounting groove 3 is also provided with a positioning component 6 for positioning the circuit board body 1. Specifically, the utility model has a novel structure and ingenious design. During assembly, the anti-wear blocks 2 are respectively arranged on both sides of the circuit board body 1, and the two sides of the circuit board body 1 are respectively inserted into the installation groove 3 from one end of the anti-wear block 2. The circuit board body 1 is pushed in along the length direction of the installation groove 3 until the positioning component 6 positions the circuit board body 1, and then the pushing is stopped. At this time, the circuit board body 1 is installed between the two anti-wear blocks 2. Due to the action of the upper anti-wear rubber strip 4 and the lower anti-wear rubber strip 5, an anti-wear effect is achieved. At the same time, since the two sides are protected by the anti-wear blocks 2, it is convenient to transport and transfer during production, and damage to the circuit board body 1 caused by wear during production, installation, and transportation is avoided. The structure is reliable, and the installation is quick and convenient.

[0023] In this embodiment, the positioning assembly 6 includes at least one elastic positioning sphere 7, and at least one positioning pit 8 is respectively provided on both sides of the upper end surface of the circuit board body 1, and the elastic positioning sphere 7 is provided corresponding to the positioning pit 8; the elastic positioning sphere 7 can be provided on the upper end surface of the inner wall of the mounting groove 3. Specifically, the circuit board body 1 is pushed in along the length direction of the mounting groove 3, and when the front end of the circuit board body 1 passes through the elastic positioning sphere 7, the elastic positioning sphere 7 is squeezed to deform it, and the circuit board body 1 is continuously pushed in until the positioning pit 8 reaches the position of the elastic positioning sphere 7, and the elastic positioning sphere 7 restores its deformation and is stuck in the positioning pit 8 to position the circuit board body 1. At this time, the circuit board body 1 has been installed in the mounting groove 3 of the anti-wear block 2, and the structure is stable, and the positioning is quick and convenient; further, the corners of the two ends of the positioning pit 8 are provided with chamfered corners, which are convenient for sliding and abutting with the elastic positioning sphere 7, and convenient for squeezing the elastic positioning sphere 7 to deform it, and then convenient for pushing out the circuit board body 1.

[0024] Furthermore, the positioning assembly 6 also includes a movable block 9 and an elastic connecting member 10. The upper end surface of the inner wall of the mounting groove 3 is provided with a movable groove 11, and the movable groove 11 is connected to the mounting groove 3. The movable block 9 is movably arranged in the movable groove 11. The upper end of the movable block 9 is connected to one end of the elastic connecting member 10, and the other end of the elastic connecting member 10 is connected to the upper end in the movable groove 11. The elastic positioning ball 7 is installed at the lower end of the movable block 9, and the elastic positioning ball 7 protrudes out of the movable groove 11. Specifically, under the above setting, when the front end of the circuit board body 1 passes through the elastic positioning sphere 7, the elastic positioning sphere 7 is squeezed to cause it to deform. At the same time, the movable block 9 is pushed upward in the movable groove 11, squeezing the elastic connecting member 10 so that the elastic connecting member 10 is compressed and continues to be pushed into the circuit board body 1 until the positioning pit 8 reaches the position of the elastic positioning sphere 7. Then, the elastic positioning sphere 7 restores its deformation and is stuck in the positioning pit 8. At the same time, the elastic connecting member 10 restores its deformation to push the movable block 9 downward, so that the elastic positioning sphere 7 is more stably stuck in the positioning pit 8, and the circuit board body 1 is reliably positioned. At this time, the circuit board body 1 has been installed in the mounting groove 3 of the anti-wear block 2.

[0025] In this embodiment, the lower end surface of the anti-wear block 2 is further provided with an anti-wear rubber pad 18. Specifically, under the above arrangement, the anti-wear rubber pad 18 further plays an anti-wear effect.

[0026] In this embodiment, both ends of the upper anti-wear rubber strip 4 and the lower anti-wear rubber strip 5 are provided with introduction slopes 13. Specifically, with the provision of the introduction slopes 13, it is convenient to insert the circuit board body 1 into the installation groove 3 from both ends of the anti-wear block 2.

[0027] In this embodiment, both ends of the upper end surface of the anti-wear block 2 are respectively provided with plug posts 14, and the upper end of the plug posts 14 is provided with elastic snap-fitting balls 15. Both ends of the lower end surface of the anti-wear block 2 are respectively provided with plug holes 16, and the upper end of the plug holes 16 is provided with a spherical cavity 17 that cooperates with the elastic snap-fitting balls 15. Specifically, under the above-mentioned setting, the stacking assembly arrangement between multiple anti-wear blocks 2 is convenient. When the circuit board body 1 of the same size needs to be stacked, multiple anti-wear components are assembled in a stacked manner. During assembly, the two adjacent upper and lower anti-wear blocks 2 are inserted into the insertion hole 16 through the plug column 14. During the insertion process, the elastic snap-fit ​​ball 15 is squeezed and deformed until it extends into the upper end of the insertion hole 16. The elastic snap-fit ​​ball 15 enters the spherical cavity 17 and restores the deformation to be snapped into the spherical cavity 17, so that the two adjacent upper and lower anti-wear blocks 2 are assembled and connected, not easy to fall off, with good structural stability, and convenient and quick stacking assembly or disassembly, and the friction between the stacked circuit board bodies 1 is avoided, thereby achieving an anti-wear effect.

Preferably, the rolling ball 12 is made of plastic material, which can avoid the metal material from contacting and conducting with the circuit board body 1, and the rolling ball 12 made of plastic material can reduce the wear on the circuit board body 1 and improve the structural reliability and stability. Specifically, under the above-mentioned setting, when the circuit board body 1 is assembled between the two anti-wear blocks 2, the circuit board body 1 is inserted from one end of the anti-wear block 2. After insertion, until the positioning pit 8 of the circuit board body 1 reaches the position of the rolling ball 12, the movable block 9 is pushed downward under the elastic force of the elastic connecting member 10, so that the rolling ball 12 falls into the positioning pit 8 to realize the positioning of the circuit board; wherein, the rolling ball 12 rotates and abuts against the circuit board body 1 to avoid wear on the circuit board body 1 and does not affect the insertion of the circuit board body 1 into the mounting groove 3; further, chamfered corners are provided at the two end corners of the positioning pit 8 to facilitate the sliding abutment with the rolling ball 12, so as to facilitate the abutment of the rolling ball 12 and thereby enable the movable block 9 to move upward in the movable groove 11 to squeeze the elastic connecting member 10 to compress and deform it, thereby facilitating the pushing out of the circuit board body 1.
