Abstract
Description
Technical Field
[0001] The utility model specifically relates to a disconnector accessory which can be flexibly spliced. Background Art
[0002] At present, small circuit breakers are widely used in low-voltage power distribution networks, mainly in various places such as industry, commerce, high-rise and residential buildings, and can provide overcurrent protection and leakage protection for electrical equipment such as motors, distribution lines, and lighting circuits. For example, the C45 type circuit breaker can achieve more functions by installing accessories, such as MX, MX+OF, MN, MV, and MN+MV series electrical accessories. However, due to the structural limitations of the C45 type circuit breaker, that is, its trip lock is at the outlet of the product, the splicing method of the accessories that match it is relatively fixed and single-direction, that is, the left splicing can only be fixed by the left splicing method, and the right splicing can only be fixed by the right splicing method. This point is very unfriendly to some customers and cannot meet the needs of customers. For manufacturers, the left splicing method and the right splicing method will cause a large difference in the internal structure. When preparing for regular stocking, two sets of product parts need to be prepared, resulting in greater inventory pressure. Utility Model Content

[0023] 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 of 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.
[0024] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0025] As shown in the figure, the utility model discloses a flexibly spliced disconnector accessory, which can be any one of MX, MX+OF, MN, MV, MN+MV, etc. All of them can adopt the technical solution of the present application, and realize the switch between left and right splicing by replacing the handle and the rotating plate. Compared with the previous solution, this solution only needs to configure two sets of handles and rotating plates, saving a lot of parts inventory.
[0026] The disconnector accessory proposed in the present application is composed of a shell, a mechanism component placed in the shell, and a handle and a rotating plate, wherein the mechanism component serves as the main device structure to realize the functions of the above-mentioned accessory. The present application takes the disconnector as an example.
[0027] The shell is composed of a first shell 1 and a second shell 2, and a accommodating space is formed between the two. The first shell 1 and the second shell 2 are both provided with a first linkage hole 3 and a second linkage hole 4. The first linkage hole and the second linkage hole on both sides are coaxially arranged, so that when located on the left side and on the right side, the position of the linkage hole corresponds to the circuit breaker.
[0028] The mechanism assembly 9 is placed in the shell. This application takes the releaser as an example. The mechanism assembly includes an operating mechanism linked with the handle and the rotating plate and a releaser used to drive the operation of the operating mechanism, that is, the operation of the releaser drives the operation of the handle and the rotating plate through the operating mechanism.
[0029] The handle 6 is detachably arranged in the housing and is linked with the mechanism assembly, and the first linkage shaft 61 of the handle can pass through the first linkage hole on either side and enter the circuit breaker through the left or right side of the circuit breaker.
[0030] A first linkage shaft is provided on the left or right side of the handle, and the first linkage shaft can pass through the first linkage hole of the first shell or the first linkage hole of the second shell, thereby realizing the left-right interchangeability of the disconnector accessory, and only two sets of mirror-image handles are required.
[0031] The rotating plate 7 is detachably arranged in the housing and is linked with the mechanism assembly, and the second linkage shaft 71 of the rotating plate can pass through the second linkage hole on either side and enter the circuit breaker through the left or right side of the circuit breaker.
[0032] Similarly, a second linkage shaft is provided on the left or right side of the rotating plate. The second linkage shaft can pass through the second linkage hole of the first shell or the second linkage hole of the second shell, thereby realizing the left and right interchange of the disconnector attachment, and only two sets of mirror-image rotating plates are required.
[0033] The first shell and the second shell are provided with a plurality of splicing holes 5, which are designed to make the connection between the two more reliable, and the splicing holes on the first shell and the second shell are coaxially arranged, so that whether they are on the left side or the right side of the circuit breaker, they are arranged correspondingly with the splicing holes on the surface of the circuit breaker, and by setting a pluggable splicing axis, it can be spliced with the circuit breaker.
[0034] The first shell is provided with a first splicing hole, and the second shell is provided with a second splicing hole, and any one or both of the first splicing hole and the second splicing hole are composed of a circular hole 52 and a non-circular hole 51, and the circular hole and the non-circular hole are arranged along the width direction of the shell.
[0035] The combination of a circular hole and a non-circular hole can be used to confine the splicing shaft between the first shell and the second shell to prevent the splicing shaft from being pulled out. At the same time, one end of the splicing shaft is set to a shape that matches the non-circular hole, such as Figure 4 As shown on the left side of the figure, it is placed in the splicing hole so that it cannot be rotated.
[0036] Or a detachable splicing shaft is provided in the splicing hole, and the splicing shaft is a round shaft, such as Figure 4 As shown on the right side of the figure, the splicing hole can be directly inserted. In this way, the splicing holes on the first shell and the second shell can be set as round holes. By setting the splicing axis between the disconnector accessory and the circuit breaker, the two can be fixed.
[0037] The surface of the splicing shaft is provided with a reinforcing rib 81 for interference fit, and the reinforcing rib is extended along the axis of the splicing shaft to increase its size so that it forms an interference fit with the splicing hole, making the fixation of the two more firm and reliable.
[0038] The first linkage hole and the second linkage hole are both arranged on the first shell and the second shell. By replacing the handle and rotating plate of the linkage shaft in different directions, the replacement of the left installation and the right installation can be realized, and other parts do not need to be replaced, thereby reducing inventory pressure and production costs.
[0039] The embodiments should not be regarded as limiting the present invention, but any improvements based on the spirit of the present invention should be within the protection scope of the present invention.
