Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically to a multilayer high-strength circuit board. Background Technology

[0002] Multilayer circuit boards are a product of the development of electronic information technology towards high speed, multifunctionality, large capacity, and small size. A multilayer circuit board refers to a printed circuit board with three or more conductive pattern layers laminated with insulating material in between, and the conductive patterns interconnected as required. Generally, a multilayer circuit board has at least three conductive layers, two on the outer surface, and the remaining layer is integrated into an insulating layer. Electrical connections between them are usually achieved through plated vias on the cross-section of the circuit board. During use, due to the large number of layers in traditional multilayer circuit boards, pins are easily damaged by pressure during subsequent use, leading to a shortened lifespan of the entire circuit board.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent with announcement number CN215581877U, announcement date 2022-01-18) provides a multilayer high-strength printed circuit board, including a body, a fixing base, a heat dissipation component, a placement slot, and fixing bolts. The body consists of several groups, each group having fixing bases on both its upper and lower sides. Both groups of fixing bases are fixedly connected to the body, and the front of each group of fixing bases has a placement slot. Each pair of bodies is fixedly connected by fixing bolts. The heat dissipation component is located between the two groups of bodies and is movably connected to the fixing base. By adding a heat dissipation component, the heat dissipation capacity of the device is improved, effectively extending its service life. By adding a partition ring, the multilayer bodies are separated, preventing pin damage caused by compression. This method effectively extends the service life of the device.

[0004] The aforementioned mechanism can separate the multiple layers of the main body by using partition rings, thereby improving its service life. However, in actual use, when the circuit boards are stacked, the compression between two circuit boards can cause damage due to the insufficient strength of the circuit boards themselves. Utility Model Content

[0005] The purpose of this invention is to provide a multilayer high-strength circuit board to solve the problem mentioned in the background art that traditional multilayer circuit boards, due to their large number of layers, are prone to pin damage during subsequent use, which in turn shortens the service life of the entire circuit board.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multilayer high-strength circuit board, comprising a circuit board body, with insulating plates installed between the circuit board bodies; a protective mechanism for protecting the circuit board body is sleeved on the outside of the circuit board body, the protective mechanism including an outer protective plate, the outer protective plate being sleeved on the outside of the circuit board body, an inner protective plate being slidably connected to the outside of the outer protective plate, and the insulating plate provided on the inside of the circuit board body can play an insulating protection role, increasing the safety of the circuit board body during use and extending the service life of the circuit board body; the outer protective plate and the inner protective plate are provided with disassembly and assembly mechanisms for disassembling and locking them.

[0007] Furthermore, a horizontal partition strip is installed on one side between the outer protective plate and the inner protective plate, and a vertical partition strip is installed at one end of each horizontal partition strip. By sleeved on both sides of the circuit board body, and by sliding the outer protective plate to the outside of the inner protective plate, the cooperation of the horizontal and vertical partition strips connects the two outer and inner protective plates. The horizontal and vertical partition strips separate the circuit board bodies, preventing pin breakage caused by stacking of circuit board bodies.

[0008] Furthermore, both the horizontal and vertical dividing strips are disposed on the surface of the circuit board body, and the thickness of the horizontal and vertical dividing strips is equal to the thickness of the outer protective plate.

[0009] Furthermore, the disassembly and assembly mechanism includes a bolt, which is threaded to the outside of the outer protective plate. The outer protective plate has a threaded groove on its side that matches the bolt. The bolt passes through the outer protective plate and extends into the interior of the inner protective plate. By rotating the bolt, the bolt passes through the outer and inner protective plates, thereby allowing the bolt to restrict the position of the outer and inner protective plates from the side, preventing the outer and inner protective plates from separating during use.

[0010] Furthermore, both the outer and inner protective plates have an "L" shaped cross-section, and the inner side of the inner protective plate is attached to the side of the circuit board body. The thickness of the outer and inner protective plates, as well as the thickness of the horizontal and vertical partition strips, prevents the two circuit board bodies from contacting each other, thereby allowing the pins on the surface of the circuit board body to be isolated and protected simultaneously. The shape of the outer and inner protective plates can protect the sides of the circuit board body, reducing collisions between the left and right sides of the circuit board body.

[0011] Furthermore, the outer side of the inner protective plate is provided with a sliding groove, and the inner side of the outer protective plate is fixedly connected with a slider that matches the sliding groove. The outer and inner protective plates are slidably connected. The inner side of the outer protective plate is provided with a slider, and the side of the inner protective plate is provided with a sliding groove. The slider and the sliding groove are adapted to each other, so that the outer and inner protective plates are slidably connected. The sliding connection makes the docking between the outer and inner protective plates more convenient and increases the flexibility during use.

[0012] Furthermore, one side of the bolt passes through the slider, and the diameter of the bolt side is smaller than the height of the slider.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By placing the inner protective plate on both sides of the circuit board body and sliding the outer protective plate to the outside of the inner protective plate, the two outer protective plates and the inner protective plate are connected by the cooperation of the horizontal and vertical partition strips. The circuit board bodies are separated by the horizontal and vertical partition strips to avoid pin breakage caused by the stacking of circuit board bodies.

[0015] Furthermore, by utilizing the thickness of the outer and inner protective plates, as well as the thickness of the horizontal and vertical partition strips, the two circuit board bodies cannot contact each other, thereby allowing the pins on the surface of the circuit board body to be isolated and protected simultaneously. The shape of the outer and inner protective plates can protect the sides of the circuit board body, reducing collisions between the left and right sides of the circuit board body.

[0016] Furthermore, the insulating plate installed on the inner side of the circuit board body can play a role in insulation protection, increase the safety of the circuit board body during use, and extend the service life of the circuit board body.

[0017] 2. The outer and inner protective plates are connected by a sliding connection. The inner side of the outer protective plate is provided with a slider, and the side of the inner protective plate is provided with a groove. The slider and the groove are adapted to each other, so that the outer and inner protective plates are connected by a sliding connection. The sliding connection makes it easier to connect the outer and inner protective plates and increases the flexibility during use.

[0018] Furthermore, by rotating the bolt, the bolt passes through the outer and inner protective plates, thereby allowing the bolt to restrict the position of the outer and inner protective plates from the side, preventing the outer and inner protective plates from separating during use.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 The technical solution shown addresses the problem of pin damage caused by friction and compression between circuit boards during stacking: This multilayer high-strength circuit board discloses a protective mechanism, including a circuit board body 1, with insulating plates 2 installed between the circuit board bodies 1; a protective mechanism for protecting the circuit board body 1 is sleeved on its outer side, including an outer protective plate 3, which is sleeved on the outer side of the circuit board body 1, and an inner protective plate 6 is slidably connected to the outer side of the outer protective plate 3; a transverse partition strip 4 is installed on one side between the outer protective plate 3 and the inner protective plate 6, and a longitudinal partition strip 5 is installed at one end between the transverse partition strips 4; both the transverse partition strips 4 and the longitudinal partition strips 5 are disposed on the surface of the circuit board body 1, and the thickness of the transverse partition strips 4 and the longitudinal partition strips 5 is equal to the thickness of the outer protective plate 3.

[0028] In this example, the insulating plate 2 provided on the inner side of the circuit board body 1 can play a role in insulation protection, increasing the safety of the circuit board body 1 during use and extending the service life of the circuit board body 1. The inner protective plate 6 is sleeved on both sides of the outside of the circuit board body 1. The outer protective plate 3 is slidably connected to the outside of the inner protective plate 6. The cooperation of the horizontal partition strip 4 and the vertical partition strip 5 connects the two outer protective plates 3 and the inner protective plate 6. The horizontal partition strip 4 and the vertical partition strip 5 are used to separate the circuit board bodies 1, avoiding pin breakage caused by the stacking of circuit board bodies 1. The thickness of the outer protective plate 3 and the inner protective plate 6, as well as the thickness of the horizontal partition strip 4 and the vertical partition strip 5, prevents the two circuit board bodies 1 from contacting each other, so that the pins on the surface of the circuit board body 1 can be isolated and protected simultaneously. The shape of the outer protective plate 3 and the inner protective plate 6 can protect the sides of the circuit board body 1, reducing collisions on the left and right sides of the circuit board body 1.

[0029] Example 2: Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The technical solution shown addresses the problem of the protective mechanism becoming damaged and difficult to disassemble after prolonged use. The multi-layer high-strength circuit board discloses a disassembly and assembly mechanism. The outer protective plate 3 and the inner protective plate 6 are provided with disassembly and assembly mechanisms for disassembly and locking. The disassembly and assembly mechanism includes a bolt 7, which is threaded onto the outer side of the outer protective plate 3. The outer protective plate 3 has a threaded groove 8 on its side that matches the bolt 7, and the bolt 7 passes through the outer protective plate 3 and extends into the interior of the inner protective plate 6. Both the outer protective plate 3 and the inner protective plate 6 have an "L"-shaped cross-section, and the inner side of the inner protective plate 6 is in contact with the side of the circuit board body 1. The outer side of the inner protective plate 6 has a sliding groove 10, and the inner side of the outer protective plate 3 is fixedly connected to a slider 9 that matches the sliding groove 10. One side of the bolt 7 passes through the slider 9, and the diameter of the bolt 7's side is smaller than the height of the slider 9.

[0030] In this example, the outer protective plate 3 and the inner protective plate 6 are slidably connected. The inner side of the outer protective plate 3 is provided with a slider 9, and the side of the inner protective plate 6 is provided with a sliding groove 10. The slider 9 and the sliding groove 10 are adapted to each other, so that the outer protective plate 3 and the inner protective plate 6 form a sliding connection. The sliding connection makes the docking between the outer protective plate 3 and the inner protective plate 6 more convenient and increases the flexibility during use. The threaded groove 8 is threadedly connected to the bolt 7. By rotating the bolt 7, the bolt 7 passes through the outer protective plate 3 and the inner protective plate 6, so that the bolt 7 can restrict the position of the outer protective plate 3 and the inner protective plate 6 from the side, preventing the outer protective plate 3 and the inner protective plate 6 from separating during use.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
