Description

Technical Field

[0001] The utility model relates to the technical field of electrical connectors, in particular to an opening and closing mechanism for a wiring protection cover. Background Art

[0002] As an important protection component in electrical equipment, an automatic circuit connector can ensure automatic power-on of the circuit after wiring. However, during operation, the connector generates certain heat, and the probes above may be affected by the external environment, such as dust and impact. These factors may have an adverse impact on the performance and lifespan of the connector. Therefore, it is particularly important to effectively protect the connector.

[0003] With the wide application of electrical equipment and the continuous development of technology, as an important part of electrical connectors, the safety and convenience of wiring protection covers have received increasing attention. Most traditional wiring protection covers adopt manual opening and closing methods, which not only increase the labor intensity of operators but also may affect the timely maintenance or troubleshooting of electrical equipment in case of emergencies. Therefore, developing an opening and closing mechanism for a wiring protection cover that can automatically open and close to improve the operation efficiency and safety of electrical equipment has become an important research direction in the current technical field of electrical connectors.

[0004] In the prior art, although some related opening and closing mechanisms for wiring protection covers have been proposed, such as an outdoor high-voltage vacuum circuit breaker disclosed in Patent CN115527797A, these mechanisms often have problems such as complex structures, inconvenient operation, or high costs. This not only increases the complexity and maintenance difficulty of the mechanism but also may lead to an increase in the failure rate. Therefore, it is necessary to design an automatic opening and closing mechanism for a wiring protection cover with a simple structure, convenient operation, and reasonable cost. Summary of the Utility Model

[0009] The side plates of the same protective cover and the side plates of the other protective cover are arranged in a crosswise manner and connected to form two fan-shaped surfaces. The connector to be protected is located between the two fan-shaped surfaces formed by the side plates, and the crosswise connection is hinged; the fixed platform is fixedly connected to the hinges at the two side plates respectively;

[0010] The push plate is fixedly connected to the cylinder piston. The push plate is located below the hinge. When the cylinder is pushed, the push plate pushes the two side plates to rotate around the hinge so that the crosswise arranged side plates are opened;

[0011] The elastic connecting piece is connected to the upper sides of the two crosswise arranged side plates on the same side, so that when the push plate is retracted, the top plates of the two crosswise arranged protective covers are closed;

[0012] The elastic connecting piece still has tension when the top plate is closed, and its elastic limit allows the top plate to be fully opened.

[0013] As a preference of the present utility model, thin cylinders are vertically arranged at the same position at the inner bottom ends of each side plate. The top of the push plate is an inverted V-shaped inclined surface, and the two surfaces of the inverted V-shaped inclined surface are in contact with the side surfaces of the thin cylinders in the closed state of the protective cover.

[0014] As a preference of the present utility model, the length of the inverted V-shaped inclined surface just satisfies that when the push plate pushes the thin cylinder to slide to the bottom end of the inverted V-shaped inclined surface, the protective cover is fully opened.

[0015] As a preference of the present utility model, the thickness of the inverted V-shaped inclined surface is 50%-100% of the length of the thin cylinder.

[0016] As a preference of the present utility model, there are two push plates, and the two push plates are respectively located below the two hinges.

[0017] As a preference of the present utility model, holes are respectively formed in the side plates, and both ends of the elastic connecting piece are connected to the holes.

[0023] As a preference of the present utility model, the elastic connecting member is a spring or an elastic cord.

[0024] The beneficial effects of the present utility model are as follows:

[0025] By arranging the protective covers in a cross manner, the present utility model realizes the automatic opening and closing of the protective covers by using the combination of a push plate, an elastic connecting member and a cylinder, which can effectively prevent dust and sundries from falling above the connector, and avoid the equipment failure problems caused thereby.

[0050] According to the inventive concept involved in the technical solution of the present utility model, the following embodiments are provided:

[0051] Embodiment, as Figure 1 shown, the present utility model provides a wiring protection cover opening and closing mechanism, including a protection cover 100, a push plate 200, a cylinder 300, an elastic connecting member 130, and a fixed table 400;

[0052] There are two pieces of the protection cover 100, the protection cover 100 includes a top plate 120 and side plates 110, each of the protection covers 100 is provided with two pieces of the side plates 110, and the two pieces of the side plates 110 are vertically fixed to both sides of the top plate 120 in the same direction;

[0053] The side plates 110 of the same protection cover 100 and the side plates 110 of the other protection cover 100 are arranged in a cross manner and connected to form two fan surfaces, and the cross connection is connected by a hinge 111; the fixed table 400 is fixedly connected to the hinge 111 at the two side plates 110 respectively;

[0054] The push plate 200 is fixedly connected to the piston of the cylinder 300, the push plate 200 is located below the hinge 111, and when the cylinder 300 is pushed, the push plate 200 pushes the two side plates 110 to rotate around the hinge 111, so that the cross - arranged side plates 110 are opened;

[0055] The elastic connecting member 130 is connected to the upper sides of the two cross - arranged side plates 110 on the same side, so that when the push plate 200 is retracted, the top plates 120 of the two cross - arranged protection covers 100 are closed.

[0056] The connector to be protected is located between two fan-shaped surfaces formed by the side plate 110. Under the action of the fixing table 400, the hinge 111 together with the protective cover 100 is fixed in place. At this time, the cylinder 300 pushes the push plate 200. Under the action of the push plate 200, the side plate 110 rotates around the hinge 111, and the top plate 120 is opened; when the protective cover 100 needs to be closed, the cylinder 300 retracts. Due to the removal of the thrust, the protective cover 100 closes under the pulling force of the elastic connecting member 130. The specific closed state is as shown in Figure 2 shown. The elastic connecting member 130 needs to have tension when the top plate 120 is closed to make the protective cover 100 tightly closed, and its elastic limit should allow the top plate 120 to be fully opened, and the elastic connecting member 130 should not be damaged due to opening the protective cover 100. Such a setting can achieve the effect of automatic opening and closing of the protective cover according to the above steps.

[0057] In a preferred embodiment, as shown in Figure 3 shown, thin cylinders 112 are vertically arranged at the same position at the bottom end of the inner side of each side plate 110. The top of the push plate 200 is an inverted V-shaped inclined surface 210. As shown in Figure 4 shown, when the protective cover 100 is in the closed state, the two surfaces of the inverted V-shaped inclined surface 210 are in contact with the side surfaces of the thin cylinders 112. By using the slope of the V-shaped inclined surface, it just makes the thin cylinder slide on its surface when pushing, and drives the side plate to rotate. Since the push plate and the side plate are separated, it is more convenient to replace parts.

[0058] Furthermore, the length of the inverted V-shaped inclined surface 210 just meets the requirement that when the push plate 200 pushes the thin cylinder 112 to slide to the bottom end of the inverted V-shaped inclined surface 210, the protective cover 100 is fully opened, as shown in Figure 5 shown. This design can prevent the elastic connecting member from being damaged due to excessive opening of the protective cover caused by too long inclined surface.

[0059] In a preferred embodiment, the thickness of the inverted V-shaped inclined surface 210 is 50%-100% of the length of the thin cylinder 112. The appropriate inclined surface thickness can ensure that it does not deviate when contacting the thin cylinder, making the device more stable.

[0060] In a preferred embodiment, there are two push plates 200, and the two push plates 200 are respectively located below the two hinges 111. The setting of the two push plates can ensure that the device is more stable, more convenient to push, and reduce the failure rate.

[0061] In a preferred embodiment, as shown in Figure 6As shown, the push plate 200 has a V-shaped structure. The two ends of the V-shaped structure are connected to the two thin cylinders 112 at the fan head. The intersection of the V-shaped structure is rotatable and fixedly connected to the piston rod of the cylinder 300. When using this design, an elastic connecting member can be not used. Since the V-shaped structure is not separated from the thin cylinder, when the push plate is removed, the protective cover can be directly driven to close. Specifically, the V-shaped structure push plate is as shown in Figure 7 shown.

[0062] In a preferred embodiment, holes 113 are respectively formed on the side plates 110, and both ends of the elastic connecting member 130 are connected to the holes 113. The provision of the holes can make the elastic connecting member be more firmly arranged on the side plates.

[0063] In a preferred embodiment, the fixing table 400 includes a fixing rod 410 and a fixing plate 420. The fixing plate 420 is as shown in Figure 8 shown;

[0064] One ends of the two fixing rods 410 are respectively connected to the two hinges 111, and the other ends of the fixing rods 410 are fixed at other immovable places;

[0065] The fixing rod 410 is horizontally fixed below the fixing plate 420. The fixing rods 410 are arranged in parallel and perpendicular to the side of the fixing plate 420. The cylinder 300 is connected to the fixing plate 420 by a right-angle bracket 500. Specifically, the cylinder 300, the right-angle bracket 500 and the bottom installation orientation diagram are as shown in Figures 9 - 11 shown. Through the settings of the right-angle bracket, the fixing rod and the fixing plate, the whole device is in a state of being interconnected to form a whole, making the device more stable.

[0066] In a preferred embodiment, the side plate 110 and the top plate 120 are integrally provided. The integral setting can make the protective cover more stable and reduce the failure rate.

[0067] In a preferred embodiment, the top plate 120 of the protective cover 100 is rectangular or semi-circular. The selection of various shapes increases the scope of application.

[0068] In a preferred embodiment, the elastic connecting member 130 is a spring or an elastic cord, which can increase the optional range of the elastic connecting member.

[0069] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
