Description

Technical Field

[0001] The utility model belongs to the technical field of circuit boards, and in particular relates to a circuit board with a protective structure. Background Art

[0002] Circuit boards, also known as printed circuit boards, contain a variety of small and precise electronic components. Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout.

[0003] During transportation after assembly by workers, traditional packaging is carried out in plastic shells. Through certain designs, the circuit boards can be protected as a whole. However, in actual use, many circuit boards are still affected. External pressure and sudden impact vibrations make the external protective shell unable to protect them well. When the protective shell is opened for use, the circuit boards are found to be damaged and cannot be used, which has a great impact on consumers. In view of the above problems, a circuit board with a protective structure is proposed. Utility Model Content

[0004] In order to solve the problems existing in the background technology, the utility model provides a circuit board with a protective structure, which has a better protective effect and can visualize the damage situation.

[0005] The utility model provides a circuit board with a protective structure, comprising a circuit board body, a plurality of positioning holes being arranged on the circuit board body, and a visible protective shell being arranged on the circuit board body; the visible protective shell comprising an upper protective shell and a lower protective shell being symmetrically arranged, the upper protective shell and the lower protective shell being hingedly connected, positioning protrusions being fixedly installed on the lower protective shell corresponding to the positioning holes, positioning pins being fixedly installed on the upper protective shell corresponding to the positioning protrusions, the positioning pins being plug-connected with the positioning protrusions, cavities being arranged in the upper protective shell and the lower protective shell, and side double-layer resin display tubes being symmetrically fixedly installed on the sides of the upper protective shell and the lower protective shell, and fluorescent agents being arranged in the side double-layer resin display tubes.

[0006] Furthermore, a plurality of auxiliary supporting protrusions are evenly and fixedly mounted on the lower protective shell, and a supporting sheet is fixedly mounted on the auxiliary supporting protrusions.

[0007] Furthermore, support columns are evenly and fixedly installed in the cavity.

[0008] Furthermore, the upper protective shell is provided with a protective cover for the electrical components corresponding to the circuit board body.

[0009] Furthermore, control sheets are symmetrically fixedly mounted on the movable ends of the upper protective shell and the lower protective shell.

[0010] Furthermore, the upper protective shell and the lower protective shell are made of polymer resin material.

[0011] Furthermore, a limiting ring is fixedly mounted on the positioning protrusion.

[0012] Beneficial effects of the utility model:

[0013] The utility model improves and optimizes the structure and designs the cavity, which can make the overall shockproof effect better while reducing the weight of the upper protective shell and the lower protective shell; the use of the designed side double-layer resin display tube and fluorescent agent can cause the upper protective shell and the lower protective shell to break when excessive bending occurs, so that users can discover it in time and avoid the circuit board when using it or purchasing it, thereby reducing unnecessary economic losses.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the description of the utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0022] Please see all instructions drawings:

[0023] A circuit board with a protective structure comprises a circuit board body 1, a plurality of positioning holes 2 are arranged on the circuit board body 1, and a visible protective shell 3 is arranged on the circuit board body 1;

[0024] The visual protective shell 3 includes an upper protective shell 301 and a lower protective shell 302 which are symmetrically arranged. The upper protective shell 301 and the lower protective shell 302 are hingedly connected. A positioning protrusion 303 is fixedly installed on the lower protective shell 302 corresponding to the positioning hole 2. A positioning pin 304 is fixedly installed on the upper protective shell 301 corresponding to the positioning protrusion 303. The positioning pin 304 is plug-connected with the positioning protrusion 303. A cavity 305 is provided in both the upper protective shell 301 and the lower protective shell 302. A side double-layer resin display tube 306 is symmetrically fixedly installed on the side of the upper protective shell 301 and the lower protective shell 302. A fluorescent agent 307 is provided in the side double-layer resin display tube 306.

[0025] As can be seen from the above description, when packaging, the circuit board body 1 is embedded in the lower protective shell 302 through the positioning protrusion 303 and the positioning hole 2, and then the upper protective shell 301 is closed. The positioning pin 304 on the upper protective shell 301 and the interference fit with the positioning protrusion 303 make the upper protective shell 301 and the lower protective shell 302 tightly connected; during transportation, the structural relationship between the cavity 305 and the support column 308 can effectively provide buffer protection. In addition, through the fluorescent agent in the side double-layer resin display tube 306, it can be clearly seen whether the upper protective shell 301 and the lower protective shell 302 are significantly bent. Once they are significantly bent, the side double-layer resin display tube 306 will be bent and broken, causing the internal fluorescent agent to leak, which users can see, thereby avoiding wrong purchases.

[0026] As a technical optimization solution of the utility model, a plurality of auxiliary support protrusions 307 are evenly and fixedly installed on the lower protective shell 302, and a support sheet 308 is fixedly installed on the auxiliary support protrusions 307;

[0027] It can be seen from the above description that the circuit board body 1 can be supported by the auxiliary supporting protrusions 307 and the supporting sheet 308, so that the circuit board body 1 is better protected.

[0028] As a technical optimization solution of the present utility model, support columns 309 are evenly and fixedly installed in the cavity 305;

[0029] It can be seen from the above description that the support column 309 can maintain the structural shape of the cavity 305, so that the overall impact resistance is better.

[0030] As a technical optimization solution of the utility model, the upper protective shell 301 is provided with a protective cover 310 corresponding to the electrical components of the circuit board body 1;

[0031] It can be seen from the above description that the protective cover 310 is designed according to different circuit board bodies 1, which can effectively protect the structure of the circuit board body 1 and reduce the material consumption.

[0032] As a technical optimization solution of the utility model, the movable ends of the upper protective shell 301 and the lower protective shell 302 are symmetrically fixedly installed with control pieces 311;

[0033] It can be seen from the above description that the user can quickly open or close the upper protective shell 301 and the lower protective shell 302 through the control piece 311 .

[0034] As a technical optimization solution of the utility model, the upper protective shell 301 and the lower protective shell 302 are made of polymer resin materials;

[0035] From the above description, we can see that this material has a wide range of uses, relatively mature technology, low price, good comprehensive performance and certain physical and mechanical strength.

[0036] As a technical optimization solution of the utility model, a limiting ring 312 is fixedly installed on the positioning protrusion 303;

[0037] It can be seen from the above description that the limiting ring 312 can conveniently support the circuit board body 1 to prevent the circuit board body 1 and the positioning protrusion 303 from descending too far.

[0038] The above describes the utility model and its implementation methods, which are not restrictive. The specific implementation method is only one of the implementation methods of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it, without departing from the purpose of the invention of the utility model, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the utility model.
