Description

Technical Field

[0001] This utility model relates to a dust cover, specifically a dust cover for wiring terminals. Background Technology

[0002] As people's safety awareness continues to increase, many countries and regions have introduced stricter safety standards for electronic products. For junction boxes with terminals, these standards require them to pass testing in an environment containing metal particles. Because of gaps in the housing of the terminals and the open structure of the terminal wiring holes, their safety performance cannot meet the aforementioned electronic product safety standards. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a terminal dust cover that can seal the gaps in the housing of the terminal block and the terminal wiring hole of the terminal block.

[0004] To solve the first technical problem mentioned above, the technical solution adopted by this utility model is as follows: a dust cover for a terminal block, comprising: an elastic shell that cooperates with the terminal block, the elastic shell having annular protrusions at both ends corresponding to each set of wiring ports on the corresponding ends of the terminal block, the elastic shell having an upward protrusion at its top corresponding to the wiring wrench of each set of wiring ports, the bottom of the elastic shell being open to form an installation opening, and the elastic shell having an annular folded edge arranged laterally inward around the installation opening.

[0005] As a preferred embodiment, in the aforementioned terminal dust cover, the elastic housing is a silicone housing.

[0006] As a preferred embodiment, in the aforementioned terminal dust cover, each set of wiring ports includes two wiring ports, and correspondingly, the annular protrusion is gourd-shaped.

[0007] As a preferred embodiment, in the aforementioned terminal dust cover, the annular protrusion is arranged in a tapered shape, with the inner end smaller than the outer end.

[0008] As a preferred embodiment, in the aforementioned terminal dust cover, a wiring mark is provided on the upwardly raised portion.

[0009] As a preferred embodiment, in the aforementioned terminal dust cover, the wiring mark is raised upwards.

[0010] The beneficial effects of this utility model are:

[0011] 1. The dust cover for the terminal block described in this utility model can cover all exposed surfaces of the terminal block except for the bottom surface that is attached to the junction box, so that the gaps of the terminal block itself and the terminal connection hole are effectively sealed. When wiring, the wire can be directly pierced and passed through the part surrounded by the annular protrusion and placed in the connection port of the terminal block.

[0012] 2. This utility model ensures the normal use of the wiring wrench by providing an upward protrusion on the top of the elastic shell that corresponds one-to-one with the wiring wrench of the terminal block.

[0013] 3. This utility model provides an annular folded edge at the mounting opening of the elastic shell, so that when the elastic shell covers the terminal block, it can completely cover the terminal block and prevent it from coming loose.

[0014] 4. This utility model makes wiring more convenient by setting the annular protrusion into a tapered arrangement with a smaller inner end and a larger outer end.

[0015] 5. This utility model makes it easier to avoid wiring mistakes by setting wiring marks corresponding to the terminals on the upward-raised part. Attached Figure Description

[0021] The following describes in detail, with reference to the accompanying drawings, a detailed embodiment of the dust cover for a wiring terminal according to this utility model.

[0022] like Figure 1 and Figure 2As shown, the present invention provides a dust cover for a terminal block, comprising: a silicone housing 2 that mates with the terminal block 1, wherein the silicone housing 2 has one end ( Figure 1 The left end of the terminal block 1 has two output-side annular protrusions 21 that correspond one-to-one with the two sets of output-side wiring ports on the corresponding end (left end) of the terminal block 1. The silicone housing 2 is located at its other end. Figure 1 The right end of the terminal 1 is provided with two input-side annular protrusions 22, each corresponding to one of the two sets of input-side wiring ports on the corresponding end (right end) of the terminal 1. Each set of input-side wiring ports includes two input-side wiring ports 12, and each set of output-side wiring ports includes two output-side wiring ports (see input-side wiring ports 12). The output-side annular protrusions 21 and input-side annular protrusions 22 are both gourd-shaped. The silicone housing 2 is provided with an upward protrusion 23 on its top, corresponding to the live wire connection wrench 13 of the terminal 1, and an upward protrusion 24 on its top, corresponding to the neutral wire connection wrench 14 of the terminal 1. Figure 3 As shown, the bottom of the silicone shell 2 is open, forming an installation opening, and the silicone shell 2 has an annular folded edge 25 arranged horizontally inward around the installation opening.

[0023] In practical applications, the input and output sides of the terminal block 1 can be interchanged; both the output-side annular protrusion 21 and the input-side annular protrusion 22 are tapered with a smaller inner end and a larger outer end; the live wire connection wrench has an upward-protruding live wire connection mark "L" on its upward-protruding part 23, and the neutral wire connection wrench has an upward-protruding neutral wire connection mark "N" on its upward-protruding part 24.

[0024] In actual use, the terminal block 1, after being covered with a dust cover, is usually installed in the junction box 3 (see [reference]). Figure 4 (As shown). When wiring, pierce the wire directly and pass it through the area enclosed by the corresponding output-side annular protrusion 21 or input-side annular protrusion 22 on the silicone housing 2. Press the corresponding live wire wrench 13 or neutral wire wrench 14 to lock the wire terminal into the corresponding input terminal 12 or output terminal of the terminal 1.

[0025] In summary, the above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent variations and modifications made to the shape, structure, features and spirit described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
