Description

Technical Field

[0001] This utility model relates to the field of copper clad laminate technology, specifically to a copper clad laminate that is easy to assemble. Background Technology

[0002] Copper-clad laminate (CCL) is a core material used in the electronics industry for manufacturing printed circuit boards (PCBs). Its structure typically consists of copper foil layers laminated with an insulating substrate using a hot-pressing process. The copper foil layer acts as a conductive carrier, directly participating in the formation of the circuit pattern; the substrate, primarily composed of materials such as resin and fiberglass cloth, provides structural support, electrical insulation, and heat dissipation. The performance of CCL directly affects the signal transmission efficiency, mechanical stability, and long-term reliability of electronic components, thus it is widely used in communication equipment, consumer electronics, automotive electronics, and other fields.

[0003] However, traditional copper-clad laminate (CCL) assembly methods have significant limitations. Currently, the installation and fixing of CCLs mainly rely on processes such as welding, riveting, or bonding, requiring pre-machining of threaded holes, slots, and other structures on the substrate surface to accommodate external connectors. This not only increases processing steps and costs, but the high temperatures generated during welding can easily cause copper foil layer warping or thermal stress concentration in the substrate, affecting circuit accuracy. More importantly, fixed mounting structures (such as welding brackets) cannot be stowed or angled, making them prone to damage to the copper foil layer during transportation, storage, or assembly in confined spaces. Furthermore, they struggle to meet flexible adaptation requirements in scenarios where installation angle adjustments are needed. In addition, traditional assembly methods lack precise positioning mechanisms, relying on manual alignment or auxiliary fixtures, resulting in low assembly efficiency and a high risk of installation deviations, making them unsuitable for the high-efficiency, precise assembly requirements of automated production lines.

[0022] 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.

[0023] like Figure 1-5 As shown, this utility model provides a copper-clad laminate that is easy to assemble. Through a reasonable structural design, the stand 3 can be stored and unfolded, which facilitates the assembly and installation of the copper-clad laminate.

[0024] The copper-clad laminate (CCL) mainly consists of a copper foil layer 1 and a substrate 2 stacked together. The copper foil layer 1 is positioned on top of the substrate 2, and the two are tightly bonded together by an adhesive layer 6. The adhesive layer 6 is uniformly coated on the contact surface between the copper foil layer 1 and the substrate 2. Through specific processes (such as hot pressing), the copper foil layer 1 and the substrate 2 are firmly bonded together, forming a stable laminated structure. This ensures that the CCL will not delaminate during subsequent use, guaranteeing the stability of its electrical and mechanical properties.

[0025] A raised positioning post 201 is located at the center of the bottom of the substrate 2. The outer side of the positioning post 201 has a polygonal structure, such as a regular hexagon or a regular octagon. This polygonal structure design facilitates precise positioning when assembling the copper-clad laminate with other components, ensuring accurate installation. Simultaneously, the positioning post 201 is detachably connected to the substrate 2, such as through threaded connection or snap-fit ​​connection. Taking the threaded connection as an example, the bottom of the positioning post has external threads, and the center of the substrate has a corresponding internal threaded hole. The positioning post 201 is screwed into the substrate by rotation, facilitating disassembly and replacement when the positioning post 201 is damaged or needs to be replaced with a different specification.

[0026] At least three receiving grooves 202 are provided circumferentially around the bottom of the substrate 2, distributed around the positioning posts 201. In this embodiment, four receiving grooves 202 are provided, evenly distributed around the positioning posts 201, to ensure the stability of the copper-clad laminate during installation. The inner wall of the receiving groove 202 has an opening communicating with the outside of the substrate, which provides space for the rotation of the stand 3. The bottom of the receiving groove 202 is also provided with a plurality of positioning slots 203, the position and number of which correspond to the positioning protrusions 303 provided on the stand 3.

[0027] A silicone layer 5 is also provided at the bottom of the receiving groove 202, which contacts one side of the tripod 3. The silicone layer 5 is glued to the bottom of the receiving groove 202 and has a certain degree of elasticity and friction. When the tripod 3 is stored in the receiving groove 202, the silicone layer 5 contacts the tripod 3, which can play a role in cushioning and fixing, preventing the tripod 3 from shaking freely in the receiving groove 202, and at the same time avoiding the tripod 3 from direct contact with the bottom of the receiving groove 202, which would cause wear and abnormal noise.

[0028] The bracket 3 is installed in the receiving groove 202. The bracket 3 includes a riveting end 301 and a mounting end 302. The riveting end 301 and the mounting end 302 are integrally formed structures and are made of metal materials with certain strength and toughness, such as stainless steel and aluminum alloy, to ensure that the bracket can withstand the weight and stress of the copper-clad laminate during installation and use.

[0029] The riveting end 301 is coaxially provided with a raised positioning protrusion 303, the shape and size of which match the positioning slot 203 at the bottom of the receiving groove 202. When installing the leg 3, the positioning protrusion 303 is aligned with the positioning slot 203 and inserted to initially fix the leg 3 in the receiving groove 202.

[0030] A pin 4 is inserted into the riveting end 301 and fixed to the bottom of the receiving groove 202 via the positioning protrusion 303. The pin 4 is made of high-strength metal material, such as carbon steel. One end of the pin 4 has a head, and the other end is threaded or fixed by riveting or other methods. During installation, the pin 4 is passed through the riveting end 301 and the positioning protrusion 303, and one end is fixedly connected to the bottom of the receiving groove 202, so that the stand 3 can rotate around the axis of the pin 4. With this fixing method, the stand 3 can achieve flexible rotation within the receiving groove 202, making it convenient to rotate the mounting end 302 into the receiving groove 202 for storage, or unfold it to the outside of the base material 2 for installation.

[0031] The mounting end 302 has mounting holes 304, the diameter of which is designed according to actual installation requirements. The mounting holes 304 are used to fix the copper-clad laminate to the corresponding equipment or bracket using fasteners such as bolts and screws.

[0032] The mounting end 302 has a downwardly recessed groove 305, and a mounting hole 304 is formed in the center of the groove 305. The groove 305 increases the structural strength around the mounting hole 304, preventing deformation of the mounting end 302 due to the force of the fasteners during installation. A washer 7, made of elastic material such as rubber or plastic, is coaxially arranged within the groove 305 and is made of the same inner diameter as the mounting hole 304, while its outer diameter is slightly larger. During installation, the fastener passes through the mounting hole 304 and the washer 7. The washer 7 acts as a buffer and seal, reducing friction between the fastener and the mounting end 302, preventing loosening, and preventing moisture and dust from entering the mounting hole, thus improving the reliability and stability of the installation.

[0033] When the copper-clad laminate does not need to be installed, the stand 3 is in the storage state. At this time, the mounting end 302 of the stand 3 is rotated around the axis of the pin 4 into the receiving groove 202. The stand 3 can be stably fixed in the receiving groove 202 without shaking, which facilitates the storage and transportation of the copper-clad laminate.

[0034] When installing the copper-clad laminate, the mounting end 302 of the stand 3 is rotated and unfolded from within the receiving groove 202 around the axis of the pin 4 to the outside of the substrate 2. Due to the contact between the silicone layer 5 and the stand 3, the stand 3 will not move arbitrarily. Then, fasteners (such as bolts) are passed through the mounting holes 304 and washers 7, and screwed into the threaded holes on the corresponding equipment or bracket. Through the tightening action of the fasteners, the copper-clad laminate is firmly installed on the equipment or bracket. During the installation process, the positioning post 201 cooperates with the positioning structure of other components for pre-positioning to ensure the accuracy of the copper-clad laminate installation position.

[0035] In summary, the copper-clad laminate provided in this embodiment achieves the storage and unfolding function of the bracket 3 through a reasonable structural design, which facilitates the assembly of the copper-clad laminate. At the same time, the use of the positioning post 201 and the silicone layer 5 together improves the accuracy and stability of the installation.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
