Description

Technical Field

[0001] The embodiments of this disclosure generally relate to the field of electrical equipment technology, and more specifically, to electrical switches. Background Technology

[0002] Auxiliary components in electrical switches are used to switch the operating state of the electrical switch and / or indicate the operating state of the electrical switch. To achieve these functions, the operator needs to connect the external wiring harness to the auxiliary components.

[0003] There are currently two common wiring schemes. In one scheme, the operator opens the faceplate and wires the auxiliary components themselves, then leads the wires out through the holes in the faceplate for further wiring. In the second scheme, the electrical switch is pre-wired to the auxiliary components before leaving the factory, with sufficiently long wires provided for the operator to connect.

[0004] However, the first wiring method is more cumbersome for the operator and carries the risk of incorrect wiring or wires being crushed. While the second wiring method avoids these risks, the length of the lead wires is difficult to control and match. Utility Model Content

[0005] In one aspect of this disclosure, an electrical switch is provided, comprising: a housing; an auxiliary element disposed within the housing and adapted to switch and / or indicate the operating state of the electrical switch; a first wiring member disposed within the housing and including a first wiring portion exposed above the housing; a connector disposed within the housing, one end of the connector being electrically connected to the auxiliary element and the other end of the connector being electrically connected to the first wiring member; and a second wiring member adapted to be connected to the first wiring portion and limited outside the housing by the first wiring portion, the second wiring member being electrically connected to the first wiring member and adapted to receive an external wire.

[0006] According to embodiments of this disclosure, auxiliary components, connectors, and a first wiring component are pre-connected and disposed within the housing, with the first wiring portion of the first wiring component protruding from the housing. The operator can complete the wiring operation by connecting a second wiring component, to which an external wire is connected, to the first wiring component, and the second wiring component is adaptable for removal from the first wiring component. This method allows for quick and repeated installation and removal of the second wiring component, reducing the operator's workload and improving satisfaction. Furthermore, the pre-connected auxiliary components, connectors, and first wiring component also reduce the risk of wiring errors or wire compression during installation. Additionally, since it is not necessary to extend a sufficiently long wire for the operator to connect, it helps solve the problem of difficulty in controlling and matching the length of the extended wire.

[0007] In some embodiments, the second connector includes a second connector portion, and the second connector portion is connected to the first connector portion.

[0008] In some embodiments, the first wiring portion includes one of a mounting groove and a mounting protrusion, and the second wiring portion includes the other of the mounting groove and the mounting protrusion.

[0010] In some embodiments, the first connector further includes at least two first conductive portions, each first conductive portion including a first end and a second end, the first ends of the at least two first conductive portions being disposed within the first connector, and the second ends of the at least two first conductive portions being disposed outside the first connector and each being electrically connected to the end of a corresponding connecting wire away from the auxiliary element.

[0011] In some embodiments, the second connector further includes at least two second conductive portions disposed within the second connector portion, each of the at least two second conductive portions being electrically connected to a first end of a corresponding first conductive portion and adapted to be connected to the external wire.

[0014] In some embodiments, the connecting groove includes a first pair of sidewalls spaced apart from each other, the first pair of sidewalls being provided with limiting members, and a first connector abutting against the limiting members.

[0015] In some embodiments, the auxiliary element includes at least one of an auxiliary contact, an undervoltage release, a shunt trip, and an energy storage motor.

[0016] It should be understood that the content described in this section is not intended to limit the key or essential features of the embodiments of this disclosure, nor is it intended to restrict the scope of this disclosure.

[0031] Embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0032] The term "comprising" and its variations as used herein signify open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "at least partially based on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "first", "second", etc., may refer to different or the same objects.

[0033] As described above, the first wiring method is cumbersome for operators, making disassembly and assembly difficult and thus reducing operator satisfaction. It also carries risks such as incorrect wiring or wire compression. While the second wiring method avoids these risks, it presents the risk of difficulty in controlling and matching the length of the lead wires. For example, excessively long lead wires hinder cost control, while excessively short lead wires increase the difficulty of wiring.

[0034] Embodiments of this disclosure provide an electrical switch to at least partially solve the aforementioned problems. In the following, [the following will be combined with...] Figures 1 to 6 The principles of this disclosure are described.

[0035] Figure 1 A partial structural schematic diagram of an electrical switch 100 according to some embodiments of the present disclosure is shown. Figure 2 It shows Figure 1 The exploded view of the electrical switch 100 shown. Figure 3 A schematic diagram of the auxiliary element 2, the first wiring member 3, and the connector 4 according to some embodiments of the present disclosure is shown. Figures 1 to 3 As shown, the electrical switch 100 described herein includes a housing 1, an auxiliary element 2, a first wiring component 3, a connector 4, and a second wiring component 5. The housing 1 serves as a mounting carrier, and the auxiliary element 2, the first wiring component 3, and the connector 4 are adapted to be coupled to the housing 1.

[0036] refer to Figure 1 and Figure 3 In some embodiments, the auxiliary element 2 is disposed within the housing 1, and the auxiliary element 2 is adapted to switch and / or indicate the operating state of the electrical switch 100.

[0037] For example, in some embodiments, auxiliary element 2 may include at least one of an auxiliary contact (OF), an undervoltage release (SD), a shunt trip (MX), and an energy storage motor (MN). The auxiliary contact is used to indicate the open / closed state of electrical switch 100. When the line voltage is too low or completely lost, the undervoltage release automatically actuates, thereby driving electrical switch 100 to trip. When the coil of the shunt trip receives an external signal, the shunt trip drives electrical switch 100 to trip immediately. The energy storage motor automatically starts after electrical switch 100 is opened to store energy for the closing mechanism of electrical switch 100. It should be understood that auxiliary element 2 may also include any element suitable for switching and / or indicating the operating state of electrical switch 100.

[0038] Figure 4 A schematic diagram of the structure of the second connector 5 and the external wire 200 according to some embodiments of the present disclosure is shown. Figures 1 to 4 As shown, in some embodiments, the first connector 3 is disposed within the housing 1. The first connector 3 includes a first wiring portion 31 exposed above the housing 1, facilitating the user to connect the second connector 5 to the first connector 3. The second connector 5 is adapted to connect to the first wiring portion 31 and is confined outside the housing 1 by the first wiring portion 31. The second connector 5 is adapted to be electrically connected to the first connector 3. The second connector 5 is adapted to connect to an external wire 200 for electrical connection. It is understood that when connecting the external wire 200 and the second connector 5, it is only necessary to connect the external wire 200 to the first connector 3 via the second connector 5, and the second connector 5 is adapted to be detached from the first connector 3. The assembly and disassembly process is quick and convenient, which helps reduce the workload of the operator and improves satisfaction.

[0039] Continue to refer to Figure 3 In some embodiments, the connector 4 is disposed within the housing 1. One end of the connector 4 is electrically connected to the auxiliary element 2, and the other end of the connector 4 is electrically connected to the first connector 3. In this way, the auxiliary element 2 is electrically connected to the first connector 3 via the connector 4, and the auxiliary element 2, connector 4, and first connector 3 can be pre-installed into the housing 1 before leaving the factory. Because the dimensions are fixed and the wire harness length and routing can be controlled, it is beneficial to reduce the risk of incorrect wiring or wire compression.

[0040] According to embodiments of this disclosure, the auxiliary element 2, connector 4, and first connector 3 are pre-connected and disposed within the housing 1, with the first connector portion 31 of the first connector 3 protruding from the housing 1. The operator can complete the wiring operation by connecting the second connector 5, which connects to the external wire 200, to the first connector 3, and the second connector is suitable for removal from the first connector. In this manner, the second connector 5 can be quickly and repeatedly installed and removed, reducing the operator's workload and improving satisfaction. Furthermore, the pre-connected auxiliary element 2, connector 4, and first connector 3 also reduce the risk of wiring errors or wire compression during installation. Moreover, since it is not necessary to extend a sufficiently long wire for the operator to connect, it helps solve the problem of difficulty in controlling and matching the length of the extended wire, thereby helping to address the issues of increased costs and wiring difficulties.

[0041] refer to Figure 3 and Figure 4 In some embodiments, where the first connector 3 includes a first connector portion 31, the second connector 5 may include a second connector portion 51. The second connector portion 51 may be connected to the first connector portion 31 to assemble the second connector 5 onto the first connector 3.

[0042] The first wiring portion 31 may include one of a mounting groove and a mounting protrusion. The second wiring portion 51 may include the other of a mounting groove and a mounting protrusion. For example, see reference... Figure 3 and Figure 4 In some embodiments, the first wiring portion 31 may include a mounting groove, and the second wiring portion 51 may include a mounting protrusion. The mounting protrusion is adapted to be disposed within and limited by the mounting groove to assemble the second wiring member 5 onto the first wiring member 3.

[0043] Figure 5 A schematic diagram of the structure of auxiliary element 2 according to some embodiments of the present disclosure is shown. For example... Figure 3 and Figure 5 As shown, in some embodiments, the auxiliary element 2 may include at least two wiring ports 21 for the connector 4 to access. The connector 4 may include at least two connecting wires 41. One end of each of the at least two connecting wires 41 is electrically connected to a corresponding wiring port 21 among the at least two wiring ports 21.

[0044] It should be noted that the numbers, values, and quantities mentioned above, as well as elsewhere in this disclosure, are exemplary and are not intended to limit the scope of this disclosure in any way. Any other suitable numbers, values, and quantities are possible. For example, depending on the specific application scenario and requirements, at least two wiring ports 21 may include three wiring ports 21, and at least two connecting wires 41 may include three connecting wires 41.

[0045] refer to Figure 2 and Figure 3 Furthermore, the first connector 3 may also include at least two first conductive portions 32. The first conductive portions 32 may, for example, include a metal component with conductive properties. Each first conductive portion 32 may extend and may include a first end 321 and a second end 322 disposed opposite to the first end 321. The first ends 321 of the at least two first conductive portions 32 are disposed within the first connector 31. The second ends 322 of the at least two first conductive portions 32 are disposed outside the first connector 3. Each of the second ends 322 of the at least two first conductive portions 32 is electrically connected to the end of the corresponding connecting wire 41 facing away from the auxiliary element 2.

[0046] In this way, the auxiliary component 2 is electrically connected to the first wiring component 3 through the connector 4, and the auxiliary component 2, connector 4 and the first wiring component 3 can be pre-installed in the housing 1, which helps to reduce the risk of wiring errors or wires being crushed during the installation process.

[0047] Continue to refer to Figure 3 and Figure 4 In some embodiments, the second connector 5 may further include at least two second conductive portions (not shown) disposed within the second connector portion 51. The second conductive portions may, for example, include conductive metal parts. When the second connector portion 51 is located within the first connector portion 31, each of the at least two second conductive portions is electrically connected to a first end 321 of a corresponding first conductive portion 32. The at least two second conductive portions are also adapted to be connected to an external wire 200. In this way, the external wire 200 is adapted to be electrically connected to the first connector 3 via the second connector 5.

[0048] Continue to refer to Figure 3 and Figure 4 In some embodiments, the second wiring portion 51 may further include at least two connection holes 511. At least two second conductive portions are each disposed within a corresponding connection hole 511. The first ends 321 of at least two first conductive portions 32 are disposed within at least two connection holes 511 and are electrically connected to the corresponding second conductive portions. That is, the first ends 321 can pass through the connection holes 511 and be electrically connected to the corresponding second conductive portions to electrically connect the first wiring member 3 to the second wiring member 5.

[0049] Continue to refer to Figure 3 and Figure 4In some embodiments, the second connector 5 may include at least one mounting portion 52. Fasteners 6, such as bolts and screws, may pass through the corresponding mounting portion 52 and connect to the first connector 3 to assemble the second connector 5 to the first connector 3. For example, the first connector 3 has at least one retaining groove 33 on the side facing away from the auxiliary element 2. One end of the fastener 6 may be disposed within the retaining groove 33. It should be understood that in other embodiments, the first connector 3 and the second connector 5 may be assembled using any other suitable connection method.

[0050] Return to reference Figure 1 and Figure 2 In some embodiments, the housing 1 may include a base 11 and a cover plate (not shown) covering the base 11. The auxiliary element 2, the connector 4, and the first connector 3 are respectively disposed within the internal cavity of the base 11. For example, a connecting groove 111 is provided on one side of the base 11 adjacent to the cover plate, and the connecting groove 111 may be located at the edge of the base 11. The first connector 3 may be disposed within the connecting groove 111 and adapted to be pressed by the cover plate to fix the first connector 3 to the base 11.

[0051] Figure 6 It shows Figure 2 An enlarged schematic diagram of part A of the electrical switch 100 shown. (See diagram below.) Figure 2 and Figure 6 As shown, in some embodiments, the connecting groove 111 may include a first pair of sidewalls 1111, a second pair of sidewalls 1112, and a groove bottom 1113. The first pair of sidewalls 1111 may be spaced apart from each other. The second pair of sidewalls 1112 may be spaced apart from each other. The first pair of sidewalls 1111 and the second pair of sidewalls 1112 are disposed on the same side of the groove bottom 1113.

[0052] When the first connector 3 is placed in the connecting groove 111, the bottom surface of the first connector 3 can abut against the bottom 1113 of the groove, one pair of sides of the first connector 3 can abut against the first pair of side walls 1111, and the other pair of sides of the first connector 3 can abut against the second pair of side walls 1112. The cover plate is adapted to press against the top surface of the first connector 3. In this way, the first connector 3 is suitable for being securely assembled in the connecting groove 111 without the need for screws or bolts, thereby reducing installation steps, saving installation time, and simplifying the product structure. Of course, the first connector 3 can also be assembled in the base 11 using screws or bolts.

[0053] refer to Figure 2 and Figure 6In some embodiments, limiting members 112 may be provided on the first pair of sidewalls 1111, and the first connector 3 may abut against the limiting members 112. In this way, the first connector 3 is adapted to be limited within the base 11 by the limiting members 112. Furthermore, when assembling the first connector 3 in the connecting groove 111, it is also beneficial to avoid the problem of machining the rounded corners interfering with the first connector 3, thereby making it suitable for reducing size requirements during the mold stage. It should be understood that in other embodiments, limiting members 112 may also be provided on the second pair of sidewalls 1112 to abut against the first connector 3.

[0054] The wiring designs according to embodiments of this disclosure can be applied to various electrical switches, including but not limited to circuit breakers. It should be understood that the wiring designs according to embodiments of this disclosure can also be applied to other electrical components, and the embodiments of this disclosure are not limiting in this regard.

[0055] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
