Background technique

The handle of the multi-stage circuit breaker needs a handle cover to connect the handles of all levels, so that the product can be better combined into a whole. At the same time, multi-level products will be assembled with different types of accessories, and the protruding ends of the accessories will also be inserted into the handle cover. Due to the different lengths of the extension ends of the attachment handles of different types, the lengths of the holes matching the extension ends of the handle sleeves are also different, so the handle sleeves have two different types with long holes and short holes. The appearance of the handle cover is the same, only the length of the inner hole is different, so it is easy to install it wrongly during assembly.

The existing method usually relies on adding small marks on different handle covers to distinguish the handle covers with long holes and short holes, and then sets the corresponding handles according to product requirements. Or use the inspection tool to detect the hole depth after installing the handle cover to judge whether it is the correct handle cover. However, the handle cover with small marks to distinguish the long hole from the short hole is easy to be ignored just like the long and short holes in the product itself. It can only be prevented by visual inspection before assembly, and the problem of installing the wrong handle cover will still occur. This in turn also leads to the fitting of the wrong type of attachment. The inspection of the inspection tool is only an inspection after assembly, and problems cannot be found before and during assembly in time.

Detailed ways

In order to have a clearer understanding of the technical features, purposes and effects of the invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings, in which the same reference numerals represent the same parts.

As shown in Figure 1, the present invention provides a handle 10, the handle 10 has a body 12 and an operating portion protruding from the body 12, the body 12 has a shaft hole 122 through which the shaft hole 122 can be The shaft of the handle 10 is arranged on a switch device, and the operation part 14 extends along the axial direction of the body 12, and the opening and closing of the switch device can be controlled by toggling the operation part 14 .

It should be noted that, in this embodiment, a protrusion 142 is protruded from the operating portion 14 .

After the original handle cover with a long hole and the handle cover with a short hole are respectively assembled on the product, it cannot be detected in appearance. If there is a wrong installation of the handle cover, after the handle cover with a short hole is wrongly installed into a handle cover with a long hole, the accessories will also be installed incorrectly, but it cannot be found in time. After this change is made to the handle, the handle of the product itself is distinguished. After the assembly is completed, the product itself determines the type of the assembled accessories, and the assembly of the handle cover will not cause the wrong type of accessories to be assembled. Moreover, such a design only needs to add small protrusions on the handle to realize the functional requirements of the product, and the structure is simple and easy to realize.

Specifically, the handle 10 can be used in conjunction with a handle cover, for example, the handle 10 is set in the handle cover.

As shown in Fig. 2 and Fig. 3, there are two kinds of existing handle covers: a handle cover 80a with a long hole and a handle cover 80b with a short hole, both of which are identical in appearance, including the inner diameter D of the hole. It's just that the length of the inner hole is different. The so-called long holes and short holes actually refer to the inner cavity extending inwardly along the extension direction of the handle cover at the end of the handle cover. The longer extension length (L1) of the inner cavity 81 can be understood as a long hole, and the inner cavity 82 with shorter extension length (L2) can be understood as a short hole.

After the handle sleeve 80a with the elongated hole 81 is set on the handle 10, the protrusion 142 on the handle 10 can at least partially penetrate into the inner cavity 81, so that in fact the extension length of the inner cavity is shortened, so that "Long holes" became "short holes".

Because the handle cover with long hole and the handle cover with short hole in the original design are the same in appearance, but the length of the inner hole is different. It is not easy to be found during the installation process, and it needs to be specially distinguished before installation. And it is easy to overlook the handle cover that leads to the wrong assembly, causing the problem of heavy work. However, in the embodiment of the present invention, after corresponding changes are made to the handle, a kind of handle cover (that is, a handle cover with long holes) can be uniformly used, which can greatly simplify the installation process. Unless otherwise clearly stated below, the handle covers mentioned are all handle covers with long holes, that is, the handle covers with a longer inner cavity extension length (L1), and the inner cavity mentioned correspondingly refers to the handle cover with a longer inner cavity. The inner cavity (or long hole) of the handle sleeve of the inner cavity L1.

As shown in FIG. 4 , specifically the protrusion 142 on the handle 10, in one embodiment of the present invention, the extension length l of the protrusion 142 in the axial direction of the body 12 is shorter than that of the inner cavity 81 at the The extension length L1 in the extension direction of the handle cover 80a, and the height d of the protrusion 142 is not greater than the diameter D of the inner cavity 81 .

After the handle 10 is inserted into the handle cover 80a, due to the existence of the protrusion 142 and its axial extension length l is shorter than the extension length L1 of the inner cavity 81 in the direction of the extension of the handle cover 80a, the inner cavity 81 can be in fact The protrusion 142 has a certain height d, but this height d will not be greater than the diameter D of the inner cavity 81, so it is ensured that only the corresponding accessories can extend into the inner cavity.

As shown in Figure 6, the present invention also provides a circuit breaker 60 with the above-mentioned handle 10, and a plurality of circuit breakers 60 as described above are combined together to constitute the circuit breaker provided by the embodiment of the present invention. Multistage circuit breaker 90 .

Such a multi-stage circuit breaker 90 also includes a handle cover 80a, which can be sleeved on the handle 10 of each circuit breaker 60 to connect the circuit breakers 60 together, and the two ends of the handle cover 80a Each part has an inner cavity 81 extending along the extension direction of the handle cover 80a. After the handle cover 80a is sleeved on the handle 10 through the gap 83, the protrusion 142 can at least partially penetrate into the inner cavity 81.

When the circuit breaker 60 or the multistage circuit breaker 90 uses such a handle 10, correspondingly, only the handle cover 80a with the long hole 81 can be used to cooperate with the handle 10. If the handle cover 80b with the short hole 82 is still used, the handle 10 just can't be inserted in the handle cover 80b, so the installer can easily distinguish which handle cover to use, which greatly simplifies the installation process.

As shown in Figure 5 again, the present invention also provides a circuit breaker 100 with accessories, including an electrical accessory 70, the electrical accessory 70 has an accessory handle 71, and the accessory handle 71 has a handle extending along the extension direction of the accessory handle 71. As shown in FIG. 4, the extended end 72 of the accessory handle 71 can at least partially (preferably integrally) extend into the inner chamber 81 at one end of the handle cover 80a, and be blocked by the protrusion 142 .

The original design requires two kinds of handle covers to realize the function of distinguishing and assembling different types of accessories. However, in this embodiment, since the handle is changed accordingly, different types of accessories can be distinguished and assembled by using a handle cover, which reduces mold and material costs and greatly saves manufacturing and maintenance costs.

Specifically, when the accessory 70 used in conjunction with the circuit breaker 60 has a shorter protruding end 72, the installer can select the switchgear (especially the circuit breaker 60) with the handle 10 provided by the embodiment of the present invention. , and select the handle cover 80a with the elongated hole 81 to cooperate with it, the annex 70 can directly cooperate with the handle cover 80a.

When the accessory used with the circuit breaker has a long extension, the installer can choose the switchgear (especially the circuit breaker) with the traditional handle, and still choose the handle cover with the slotted hole to cooperate with it , the accessories can be directly matched with the handle cover.
