Description

Technical Field

[0001] The utility model relates to electrical equipment, in particular to a circuit board component with a stable power interface connection. Background Art

[0002] 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. Circuit boards can be called printed circuit boards or printed circuit boards, among which FPC circuit boards have high reliability and excellent flexibility. They have the characteristics of high wiring density, light weight, thin thickness, and good bendability.

[0003] The Chinese patent with patent number CN200320100607.4 discloses a "circuit board assembly", in which upper and lower cover structures are respectively arranged on the upper and lower parts of the circuit board, which can cover part of the electrical connector on the circuit board, and can effectively prevent electromagnetic interference when the electronic components on the circuit board transmit signals in a high-frequency environment;

[0004] This structure has certain advantages, but still has some shortcomings:

[0005] Its power interface adopts a straight-plug structure, and the power plug is inserted into the power interface. During the use of this structure, there is a possibility that the power plug becomes loose after being inserted, resulting in poor contact between the power plug and the power interface, affecting the use of the electrical equipment. In addition, poor contact at the power interface will hinder the transmission of current and limit the transfer of electrical energy, seriously affecting the performance of the electrical equipment, causing faults such as overheating, a significant reduction in current, and failure of the electrical switch, which is not conducive to use. In addition, the power interface is not used for a long time and is exposed to the outside world, which is prone to dust accumulation, and the power interface area is small, which is not easy to clean. Utility Model Content

[0006] The utility model aims to overcome the shortcomings of the prior art and provide a circuit board assembly with a stable power interface connection.

[0007] The purpose of the utility model is achieved through the following technical solutions: a circuit board assembly with a stable power interface connection, comprising a housing, a circuit board assembly, a power interface, and a reinforcement assembly;

[0008] A circuit board assembly is installed inside the housing; a power interface is connected to the front end of the circuit board assembly;

[0009] The reinforcement assembly is bolted to the front end of the housing, and a power interface is wrapped inside the reinforcement assembly;

[0010] The reinforcement assembly includes a mounting part, a fixing plate, a supporting plate, an elastic clamping rod, a transparent protective plate, and a gravity plate. The mounting part is fixed to the front end of the outer shell by bolts, a fixing plate is fixed inside the mounting part, the bottom end of the supporting plate is fixed to the fixing plate, and an elastic clamping rod is provided at the top end thereof, the top end of the transparent protective plate is hingedly connected to the fixing plate, and a gravity plate is fixed to the bottom end of the transparent protective plate.

[0011] Preferably, the mounting member includes an assembly, a connecting groove, and an embedded plate. The assembly is fixed to the front end of the shell by bolts, and a fixing plate is fixed inside the assembly. A connecting groove is provided at the right end of the assembly, and the right end of the embedded plate is fixed to the assembly.

[0012] In a further preferred embodiment, the support plate and the elastic clamping rod are provided in two groups, which are symmetrically distributed at the upper and lower ends of the fixing plate, so as to facilitate clamping of the power plug embedded inside and avoid the power plug from loosening and causing poor contact with the circuit board assembly.

[0013] In a further preferred embodiment, a rubber pad is fixed on the surface of the elastic clamp rod to play a protective role, thereby preventing the metal body of the elastic clamp rod from continuously experiencing large friction when the power plug is inserted or removed, thereby preventing the surface of the power plug from being damaged.

[0014] In a further preferred embodiment, the embedding plate can be embedded in the interior of the connecting groove in another group of the reinforcement components, so as to facilitate the end-to-end connection of multiple groups of reinforcement components for storage, reduce the loss caused by the scattered reinforcement components, and improve the safety of the storage and placement of the reinforcement components.

[0015] In a further preferred embodiment, the bottom end of the transparent protective plate is lower than the bottom end of the mounting piece, so that the transparent protective plate can shield the interior of the mounting piece and further shield the power interface, thereby preventing dust from entering and accumulating, thereby reducing the number of times the power interface needs to be maintained due to dust accumulation.

[0016] In a further preferred embodiment, an elastic rubber sleeve is fixed inside the connection groove to enhance the connection, facilitate stable embedding of the embedding plate, and achieve a stable connection between the two groups of reinforcement components.

[0017] In a further preferred embodiment, the transparent protective plate is made of a PVC transparent plate, which has high transparency, light weight, and is economical and practical.

[0018] In a further preferred embodiment, the elastic clamping rod is made of alloy spring steel, has excellent elastic restoring force, is not easy to break or damage, and is highly practical.

[0019] The utility model has the following advantages:

[0020] The utility model has the function of protecting the power interface from dust by arranging a reinforcement component. After the power interface is inserted into the power plug, the power plug can be reinforced up and down by using an elastic clamp rod, effectively avoiding the situation where the power plug is loosely connected and causes poor contact with the circuit board component, thereby reducing the situation where power transmission is blocked and parts are heated, and effectively reducing energy waste. During use, the transparent protective plate relies on the gravity plate fixed at the bottom to achieve stable placement and efficient dust prevention. The reinforcement component has a simple structure, high efficiency and strong practicality.

[0021] The utility model provides mounting parts, which facilitate the end-to-end connection of multiple groups of reinforcement components, thereby realizing integrated storage of multiple groups of reinforcement components and avoiding the situation where the reinforcement components are difficult to collect or even lost due to being too scattered. By embedding the embedded plate into the connecting groove of another group of reinforcement components, an embedded connection is realized, thereby realizing the integrated placement of multiple groups of reinforcement components.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] like Figure 1 As shown, a circuit board assembly with a stable power interface connection includes a shell 1, a circuit board assembly 2, a power interface 3, and a reinforcement assembly 4; the circuit board assembly 2 is installed inside the shell 1; the front end of the circuit board assembly 2 is connected to the power interface 3; the reinforcement assembly 4 is bolted to the front end of the shell 1, and the power interface 3 is wrapped inside it.

[0035] like Figure 2-3As shown, a circuit board assembly with a stable power interface connection, the reinforcement assembly 4 includes a mounting member 41, a fixing plate 42, a support plate 43, an elastic clamping rod 44, a transparent protective plate 45, and a gravity plate 46. The mounting member 41 is fixed to the front end of the housing 1 by bolts, the fixing plate 42 is fixed inside the mounting member 41, the bottom end of the support plate 43 is fixed to the fixing plate 42, and the top end thereof is provided with an elastic clamping rod 44, the top end of the transparent protective plate 45 is hinged to the fixing plate 42, and the bottom end of the transparent protective plate 45 is fixed to the gravity plate 46.

[0036] In this embodiment, two groups of support plates 43 and elastic clamping rods 44 are provided, which are symmetrically distributed at the upper and lower ends of the interior of the fixed plate 42, so as to clamp the power plug embedded inside and prevent the power plug from loosening and causing poor contact with the circuit board assembly 2. A rubber pad is fixed on the surface of the elastic clamping rod 44 to play a protective role and prevent the metal body of the elastic clamping rod 44 from constantly generating large friction when the power plug is inserted or plugged out, causing damage to the surface of the power plug. The bottom end of the transparent protective plate 45 is lower than the bottom end of the mounting member 41, so that the transparent protective plate 45 can block the interior of the mounting member 41, and then block the power interface 3 to prevent dust from entering and accumulating, thereby reducing the number of times the power interface 3 is maintained due to dust accumulation. Moreover, the gravity plate 46 fixed at the bottom makes the transparent protective plate 45 affected by gravity and always keeps in a downward state, thereby playing a stable protection role and preventing dust from entering.

[0037] like Figure 4-5 As shown, a circuit board component with a stable power interface connection, the mounting part 41 includes an assembly body 411, a connecting groove 412, and an embedded plate 413. The assembly body 411 is fixed to the front end of the housing 1 by bolts, and a fixing plate 42 is fixed inside it. A connecting groove 412 is opened at the right end of the assembly body 411, and the right end of the embedded plate 413 is fixed to the assembly body 411.

[0038] In this embodiment, the embedding plate 413 can be embedded in the interior of the connecting groove 412 in another group of reinforcement components 4, so as to facilitate the end-to-end connection of multiple groups of reinforcement components 4, facilitate storage, reduce the loss caused by the scattered reinforcement components 4, and improve the safety of the storage and placement of the reinforcement components 4. An elastic rubber sleeve is fixed inside the connecting groove 412 to enhance the connection, facilitate the stable embedding of the embedding plate 413, and realize the stable connection between the two groups of reinforcement components 4.

[0039] The working process of the utility model is as follows: the assembly 411 is installed at the front end of the housing 1 by bolts, and the middle of the assembly 411 is wrapped with the power interface 3;

[0040] When inserting the power plug, the transparent protective plate 45 is flipped upwards, and then the power plug is inserted into the power interface 3. During the insertion process, the elastic clamping rod 44 is deformed by the extrusion of the power plug. After the power plug is stably inserted, the elastic restoring force of the elastic clamping rod 44 allows it to be firmly extruded and tightly attached to the power plug, thereby clamping the power plug and making it firmly contact with the power interface 3, effectively avoiding the power plug from loosening;

[0041] When the power plug is not inserted into the reinforcement component 4, the transparent protective plate 45 is affected by the gravity plate 46 and always remains in a vertical downward state, protecting the power interface 3 inside and isolating it from the outside world, thereby avoiding dust accumulation.

[0042] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
