Description

Technical Field

[0001] The utility model relates to the technical field of plum blossom contacts, and in particular to a plum blossom contact which can be quickly disassembled and assembled. Background Art

[0002] The plum blossom contact is generally used in primary conductive fields such as high-voltage vacuum circuit breakers, center cabinets, and trolleys to provide electrical connection functions. It realizes the transmission of power supply, signals, etc. by plugging the contact into the socket. The plum blossom contact is usually made of copper alloy and other materials, and has the characteristics of good conductivity, wear resistance, and corrosion resistance. Some products are processed by T2 copper plate fine stamping, and the surface is plated with thick silver for anti-discoloration treatment to ensure long-term discoloration and beautiful appearance. The multi-point touch design of the plum blossom contact allows the arc energy to be distributed to each contact point, reducing the arc energy on each contact point, thereby effectively protecting the circuit breaker. The multi-point touch design can distribute the current to multiple contacts, avoiding the contact fusing caused by excessive single-point load, and extending the service life of the circuit breaker. The plum blossom contact has a large contact area and a small contact resistance, which can effectively prevent the oxidation of the silver layer, the reduction of the contact area, and the increase of the contact resistance, thereby improving the reliability and service life of the circuit breaker; the plum blossom contact is shaped like a plum blossom and consists of multiple arc contacts. This design allows the contacts to open simultaneously when the circuit breaker is opened, effectively cutting off the current.

[0003] The patent specification with the announcement number CN213647416U discloses a plum blossom contact disassembly and assembly tool, including a fixed rod, the surface of the fixed rod is fixedly connected to a fixed tube, the inner wall of the fixed tube is slidably connected to a connecting rod, the end of the connecting rod away from the fixed tube is fixedly connected to a rotating seat, the inner wall of the rotating seat is rotatably connected to a prying tube through a rotating shaft, the surface of the fixed rod is provided with an external thread groove, the surface of the external thread groove is threadedly connected to a rotating sleeve, the inner wall of the rotating sleeve is provided with a tapered groove, and the inner wall of the tapered groove overlaps with one end of the prying tube. The plum blossom contact disassembly and assembly tool, by providing a rotating sleeve, a fixed rod, a prying tube and an arc-shaped limit block, is convenient for inserting the arc-shaped limit block into the interior of the spring, rotating the rotating sleeve, so that the rotating sleeve squeezes the six prying tubes and stretches the spring, thereby facilitating the loading and unloading of the plum blossom contact, not only protecting the spring, but also preventing the maintenance personnel from injuring their hands, and being safer.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: the above device is not convenient for synchronously carrying the installation components of the plum blossom contact during use, and it is often necessary to assemble multiple parts before the plum blossom contact can be installed. On the one hand, the components need to be constantly disassembled and assembled, and on the other hand, it is not convenient to carry and parts are prone to dispersion. Therefore, further improvement is needed. Utility Model Content

[0005] The present utility model provides a plum blossom contact that can be quickly disassembled and assembled, solving the problem in the related art that it is not convenient to carry the installation components of the plum blossom contact synchronously.

[0006] The technical solution of the present utility model is as follows:

[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of the present utility model.

[0025] Embodiment 1

[0026] As Figures 1 to 3As shown in the figure, this embodiment proposes a quick-disassembly and quick-assembly plum blossom contact, which includes a plum blossom contact body 1. A connecting column 2 is arranged inside the plum blossom contact body 1. A mounting member 3 is fixedly connected to the bottom of the connecting column 2. Fixed seats 4 are fixedly connected to both sides of the outside of the plum blossom contact body 1. Fixed rods 5 are fixedly connected to the inside of both fixed seats 4. Fixed plates 6 are fixedly connected to the outside of both fixed rods 5. Connecting seats 7 are fixedly connected to the tops of both fixed plates 6. Rotating rods 8 are arranged inside both connecting seats 7. A stress plate 10 is fixedly connected to the outside of the connecting column 2.

[0027] In this embodiment, the mounting member 3 is set in a conical shape, and the top of the mounting member 3 is in contact with the bottom of the plum blossom contact body 1, which can facilitate the connection of the mounting member 3 and the limiting work of the plum blossom contact body 1.

[0028] In this embodiment, the two fixed seats 4 are symmetrically distributed. The two rotating rods 8 are respectively connected to the two connecting seats 7 through damping bearings, which can facilitate the rotation of the rotating rods 8.

[0029] In this embodiment, the two rotating rods 8 are both set in an L shape, and limiting plates 9 are fixedly connected to the inner ends of the two rotating rods 8, which can facilitate the rotation of the limiting plates 9.

[0030] In this embodiment, the two limiting plates 9 are both set in a semi-circular arc shape, and the top of the limiting plate 9 is in contact with one side of the bottom of the stress plate 10, which can facilitate the support of the stress plate 10 by the limiting plate 9.

[0031] In this embodiment, the two limiting plates 9 are distributed in a circular shape, and the cross-section between the two limiting plates 9 is circular, which can facilitate the adaptation of the limiting plates 9.

[0032] During use, when the work of installing the plum blossom contact body 1 is required, first, the staff needs to move the plum blossom contact body 1. During the movement of the plum blossom contact body 1, the mounting member 3 and the connecting column 2 will be driven to move synchronously. Then, the mounting member 3 is connected to the device to be connected. After that, the staff rotates the two rotating rods 8 clockwise and counterclockwise respectively. After the rotation of the rotating rod 8, the limiting plate 9 will be driven to rotate synchronously. During the rotation of the limiting plate 9, it will leave the side of the force-bearing plate 10 synchronously. At this time, the connecting column 2, the force-bearing plate 10 and the mounting member 3 are all in the unlocked state. Then, the staff prepares the external pressing plate. When installing the plum blossom contact body 1, the pressing plate can be passed through the inside of the connecting column 2 and the force-bearing plate 10, and then the pressing plate is pressed. During the pressing process of the pressing plate, it will perform the pressing work synchronously. During the process of the plum blossom contact body 1 being stressed, it will deform under the guidance of the mounting member 3, so that the plum blossom contact body 1 can slide into the external device through the mounting member 3 for connection work. At this time, the plum blossom contact body 1 is separated from the outer surface of the mounting member 3, and then the staff can take out the connecting column 2 and the mounting member 3, thus ensuring the complete set movement of the components during the installation of the plum blossom contact body 1 and avoiding the situation of the components being separated from the plum blossom contact body 1 during carrying.

[0033] Embodiment 2

[0034] As Figure 4 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes that vertical plates 11 are fixedly connected to the outside of the two rotating rods 8, and limiting clamping plates 12 are fixedly connected to the inner sides of the two vertical plates 11, which can facilitate the rotation work of the limiting clamping plates 12.

[0035] In this embodiment, the bottom of the limiting clamping plate 12 is in contact with one side of the top of the force-bearing plate 10, and the shape of the limiting clamping plate 12 is set to a U shape, which can support the force-bearing plate 10 through the limiting clamping plate 12.

[0036] During use, when the work of connecting the components is required after disassembling the plum blossom contact body 1, the staff needs to pass the connecting column 2 through the inside of the plum blossom contact body 1 and the outer surface of the mounting member 3 to be in contact with the bottom of the plum blossom contact body 1. Then, the staff rotates the two rotating rods 8 counterclockwise and clockwise respectively. During the rotation of the rotating rod 8, the limiting plate 9 will be driven to rotate synchronously. During the rotation of the limiting plate 9, the vertical plate 11 and the limiting clamping plate 12 will be driven to rotate synchronously. At the same time, both the limiting clamping plate 12 and the limiting plate 9 will limit the force-bearing plate 10, thereby ensuring the connectivity and limitability between the plum blossom contact body 1 and the components.

[0037] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
