Description

Technical Field

[0001] The embodiments disclosed herein relate generally to the field of electrical equipment, and more particularly to a contact assembly and electrical equipment. Background Technology

[0002] In high-voltage direct current (HVDC) systems, the arc is more difficult to extinguish because the direct current does not cross zero, thus requiring higher clearance. In some conventional electrical equipment, two sets of contacts connected in series can be incorporated into the switch or plug-in structure. When the double-contact structure is disconnected, the current must pass through two air gaps to conduct, increasing the total clearance length and thus improving the safety and reliability of the equipment.

[0039] 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.

The term "based on" means "at least partially based on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment".

[0041] In some conventional electrical equipment, two sets of contacts connected in series can be installed in switches or sockets. When the double-contact structure is disconnected, current must pass through two air gaps to conduct, increasing the total electrical clearance length and thus improving the safety and reliability of the equipment. However, there may be a height difference between the two stationary contacts during installation. When the two moving contacts are close to the two stationary contacts, one of the moving contacts will abut against the corresponding stationary contact, while the other moving contact will have a gap with the corresponding stationary contact. Such a gap can generate a large electric arc when the circuit makes or breaks, leading to severe burning of the contact assembly.

[0042] Embodiments of this disclosure provide a contact assembly and an electrical device. The contact assembly includes a base, a pair of stationary contacts, a pair of moving contacts, a first support member, and an electrical connector. The pair of stationary contacts are spaced apart from each other and disposed adjacent to the base. The pair of moving contacts are spaced apart from each other. The first support member is rotatably coupled to the base about a first axis. The first support member can be switched between a first position and a second position. The electrical connector is electrically coupled to the pair of moving contacts and is rotatably coupled to the first support member about a second axis. The second axis is perpendicular to the first axis. When the first support member is in the first position, the pair of moving contacts are separated from the pair of stationary contacts. When the first support member is in the second position, the pair of moving contacts can rotate about the second axis to abut against the pair of stationary contacts respectively. With this arrangement, a height difference exists between the pair of stationary contacts during installation, and the pair of moving contacts can rotate about the second axis to abut against the pair of stationary contacts respectively. When the circuit is connected, the paired moving contacts can make stable contact with the paired stationary contacts, thereby avoiding arcing and burning of the contact assembly, which helps to improve the service life of the contact assembly.

[0043] The following will combine Figures 1 to 10 To describe in detail the principles of this disclosure, wherein Figures 1 to 6 The structure of a contact assembly 100 according to some embodiments of this disclosure is shown. Figure 7 and Figure 8 The structure of the contact assembly 100 according to other embodiments of this disclosure is shown. Figure 9 and Figure 10 The structure of a contact assembly 100 according to further embodiments of this disclosure is shown. Firstly, in conjunction with... Figures 1 to 6 The principle of the contact component 100 of some embodiments of this disclosure will be described in detail below.

[0044] like Figure 1 As shown, the contact assembly 100 includes a base 10, a pair of stationary contacts 20, a pair of moving contacts 30, a first support 40, and an electrical connector 31. The base 10 can be made of an insulating material, such as a non-conductive material like plastic or ceramic. In some examples, the base 10 may have an internal cavity structure. The base 10 may completely surround or at least partially surround the pair of moving contacts 30, thereby providing a stable foundation for the movement of the moving contacts 30. In some embodiments, the base 10 may include multiple parts, such as a left half and a right half. When these two parts are combined, they can support other structures.

[0045] like Figure 1As shown, a pair of stationary contacts 20 are spaced apart from each other and disposed adjacent to the base 10. The position of the pair of stationary contacts 20 relative to the base 10 remains unchanged. When a pair of moving contacts 30 move relative to the base 10, they can move closer to or further away from the pair of stationary contacts 20. In some embodiments, the pair of stationary contacts 20 can be directly fixed to the base 10, so that the base 10 can maintain a stable distance and position between the pair of stationary contacts 20. In other embodiments, the pair of stationary contacts 20 can be fixed to the housing of the electrical equipment, while the base 10 is mounted on the housing of the electrical equipment. In this way, the pair of stationary contacts 20 and the base 10 can also be fixed indirectly, thereby ensuring the relative position between the contacts.

[0046] like Figure 2 As shown, a pair of moving contacts 30 are spaced apart from each other and electrically coupled to an electrical connector 31. Through the electrical coupling effect of the electrical connector 31, not only can the distance between the pair of moving contacts 30 be maintained, but current can also be conducted between the pair of moving contacts 30.

[0047] like Figures 2 to 4 As shown, a first support member 40 is rotatably connected to a base 10 about a first axis R1, and the first support member 40 can switch between a first position and a second position. An electrical connector 31 is rotatably connected to the first support member 40 about a second axis R2 perpendicular to the first axis R1. When the first support member 40 is in the first position, a pair of moving contacts 30 are separated from a pair of stationary contacts 20. When the first support member 40 moves to the second position, the pair of moving contacts 30 can rotate about the second axis R2, thereby contacting the pair of stationary contacts 20 respectively.

[0048] With this arrangement, even if the pair of stationary contacts 20 are uneven during installation, the pair of moving contacts 30 can still adaptively abut against the pair of stationary contacts 20 by rotating around the second axis R2. When the circuit is connected, the pair of moving contacts 30 can maintain stable contact with the pair of stationary contacts 20, thereby reducing arc erosion of the contacts and extending the service life of the contact assembly 100.

[0049] In some embodiments, such as Figure 3 and Figure 4 As shown, the contact assembly 100 also includes a second support 50. The second support 50 is rotatably coupled to the first support 40 about a second axis R2. The electrical connector 31 is coupled to the second support 50. With this arrangement, when the second support 50 rotates about the second axis R2, the electrical connector 31 can rotate with the second support 50, thereby driving a pair of moving contacts 30 to rotate about the second axis R2.

[0050] In some embodiments, the first support member 40 may include a stop portion. The stop portion can limit the rotation angle of the second support member 50 when it rotates about the second axis R2, for example, ±5°. In this way, the pair of moving contacts 30 not only have the ability to accommodate the height difference between the pair of stationary contacts 20, but also have contact stability under the action of the stop portion.

[0051] It should be noted that the figures, values, etc., mentioned above and elsewhere in this disclosure are exemplary and are not intended to limit the scope of this disclosure in any way. Any other suitable figures or values ​​are possible.

[0052] In some embodiments, the electrical connector 31 can be directly coupled to the first support member 40. As an example, the first support member 40 includes a rotating pin. The electrical connector 31 includes a bent connecting portion with a pin hole. The rotating pin is rotatably coupled to the pin hole. In this way, the electrical connector 31 can not only fix a pair of moving contacts 30, but also serve as a base for rotation about a second axis R2. Direct coupling of the electrical connector 31 to the first support member 40 also reduces the number of components in the contact assembly 100, thereby reducing costs.

[0053] In some embodiments, such as Figure 3 and Figure 4 As shown, the electrical connector 31 can be made of a conductive material, such as copper, aluminum, or an alloy. The electrical connector 31 may include a first coupling portion 311 and a second coupling portion 312. The second coupling portion 312 can be bent from the edge of the first coupling portion 311. When assembling the contact assembly 100, the first coupling portion 311 can be abutted against the second support member 50, and then fixed to the second support member 50 by the second coupling portion 312 at the edge of the first coupling portion 311. In this way, the electrical connector 31 is fixed to the second support member 50 by its own structure, which reduces the number of assembly parts and thus improves assembly efficiency.

[0054] In some embodiments, such as Figure 3 and Figure 4 As shown, the first coupling portion 311 may include a limiting hole 313. The second support member 50 may include a limiting portion 51 disposed on the side facing the first coupling portion 311. With this arrangement, when the first coupling portion 311 abuts against the second support member 50, the limiting portion 51 can be inserted into the limiting hole 313, thereby limiting the relative displacement between the electrical connector 31 and the second support member 50, which helps to improve the positional stability of the pair of moving contacts 30.

[0055] In some embodiments, such as Figure 3 and Figure 4As shown, the first coupling portion 311 may include a plurality of limiting holes 313. The second support member 50 may include a plurality of limiting portions 51 disposed on one side facing the first coupling portion 311. The plurality of limiting portions 51 are respectively inserted into the plurality of limiting holes 313. It should be understood that the number of limiting holes 313 and limiting portions 51 can be set as needed, and this disclosure is not intended to limit them.

[0056] In some embodiments, such as Figure 4 and Figure 5 As shown, the first support member 40 includes a groove 41 and a pair of pins 42. The pair of pins 42 are respectively arranged on adjacent sides within the groove 41, and the central axis of the pair of pins 42 coincides with the second axis R2. The second support member 50 can be placed within the groove 41 and is rotatably coupled to the pair of pins 42. In this way, the second support member 50 is rotatably coupled to the first support member 40 about the second axis R2.

[0057] In other embodiments, a pair of pins 42 are detachably coupled to the first support member 40 and the second support member 50. For example, a pair of first pin holes are provided on the first support member 40, and a pair of second pin holes are provided on the second support member 50. During installation, the second support member 50 can be placed in the groove 41 of the first support member 40, and then the pair of pins 42 can be inserted into the corresponding first pin holes and second pin holes, respectively. In this way, the second support member 50 can be rotatably coupled to the first support member 40 about the second axis R2.

[0058] In some embodiments, such as Figure 4 and Figure 5 As shown, the contact assembly 100 also includes an elastic element 60. The elastic element 60 circumferentially surrounds one of the pair of pins 42. The elastic element 60 abuts against the sidewalls of the second support 50 and the recess 41. The elastic element 60 is configured to apply a force to the second support 50, causing the second support 50 to abut against the first support 40. With this arrangement, the elastic element 60 increases the rotational damping between the second support 50 and the first support 40, allowing the rotated second support 50 to remain in its current position, thereby ensuring stable contact between the pair of moving contacts 30 and the pair of stationary contacts 20.

[0059] In some embodiments, such as Figure 4 and Figure 5As shown, the elastic member 60 includes an annular spring. The annular spring surrounds one of a pair of pins 42. The first support member 40 also includes a first protrusion 43 adjacent to one of the pins 42. The second support member 50 also includes a second protrusion 52 disposed on the side facing the first protrusion 43. The annular spring is disposed between and abuts against the first protrusion 43 and the second protrusion 52. With this arrangement, the first protrusion 43 and the second protrusion 52 can cause a certain amount of deformation in the annular spring, thereby bending the originally flat annular spring. The bent annular spring can apply a force to the second support member 50, causing the second support member 50 to abut against the first support member 40, thereby increasing the rotational damping between the first support member 40 and the second support member 50. The small size of the annular spring reduces the space occupied within the first support member 40, contributing to the structural simplification of the contact assembly 100.

[0060] In other embodiments, such as Figure 6 As shown, the elastic element 60 includes an annular spring. The annular spring includes a plurality of corrugated portions 61 evenly arranged in the circumferential direction. After the annular spring is mounted on the pin 42, at least one of the corrugated portions 61 abuts against the first support member 40, and the remaining corrugated portions 61 abut against the second support member 50. With this arrangement, when the second support member 50 is installed in the groove 41 of the first support member 40, the second support member 50 and the first support member 40 compress the plurality of corrugated portions 61 of the annular spring, thereby causing a certain deformation of the annular spring. The deformed annular spring can apply a force to the second support member 50, causing the second support member 50 to abut against the first support member 40, thereby increasing the rotational damping between the first support member 40 and the second support member 50.

[0061] In some embodiments, such as Figure 1 and Figure 2 As shown, the contact assembly 100 also includes an insulating partition 70. The insulating partition 70 is disposed between a pair of stationary contacts 20. With this arrangement, the insulating partition 70 can prevent accidental short circuits between the pair of stationary contacts 20, reduce the risk of arcing and sparking, and thus protect the circuit from damage.

[0062] The following will combine Figure 7 and Figure 8 The principles of the contact assembly 100 according to other embodiments of this disclosure will be described in detail below. The structure and connection of the contact assembly 100 in other embodiments will also be described. Figures 1 to 6 Some of the described embodiments have similar structures. The differences between them will be described primarily below, while identical parts will not be repeated.

[0063] like Figure 7 and Figure 8As shown, the contact assembly 100 includes two pairs of moving contacts 30, two electrical connectors 31, and two pairs of stationary contacts 20. The first support member 40 has a symmetrical structure and includes opposing first ends 401 and second ends 402. When the first support member 40 rotates counterclockwise about a first axis R1, the first end 401 of the first support member 40 sinks, while the second end 402 of the first support member 40 rises. The two electrical connectors 31 are rotatably coupled to the first support member 40 about their respective second axes R2. Each electrical connector 31 is electrically coupled to a corresponding pair of moving contacts 30.

[0064] When the first support member 40 is in the first position, a pair of moving contacts 30 at the first end 401 of the first support member 40 are separated from a pair of corresponding stationary contacts 20, while a pair of moving contacts 30 at the second end 402 of the first support member 40 respectively abut against a pair of corresponding stationary contacts 20.

[0065] When the first support member 40 is in the second position, a pair of moving contacts 30 at the second end 402 of the first support member 40 are separated from a pair of corresponding stationary contacts 20, while a pair of moving contacts 30 at the first end 401 of the first support member 40 respectively abut against a pair of corresponding stationary contacts 20.

[0066] Using this arrangement, the contact assembly 100 can connect and disconnect two circuits, and can put the two circuits in different states, thus making it suitable for applications requiring circuit switching.

[0067] like Figure 7 and Figure 8 As shown, the first support member 40 also includes two grooves 41 respectively disposed at the first end 401 and the second end 402, and two sets of pins 42. The two sets of pins 42 are respectively disposed in the two grooves 41 and coupled to the sidewalls of the grooves 41.

[0068] As an example, each set of pins 42 includes a single long pin 42. The single long pin 42 is coupled to two adjacent sidewalls of the corresponding groove 41. The electrical connector 31 is rotatably coupled to the corresponding single long pin 42.

[0069] As other examples, such as Figure 8 As shown, each set of pins 42 includes two short pins 42. The two short pins 42 are respectively coupled to adjacent sidewalls of the corresponding grooves 42. Each electrical connector 31 also includes a pair of connecting portions 314 disposed at the edge. The pair of connecting portions 314 are rotatably coupled to the corresponding two short pins 42.

[0070] With this arrangement, the two electrical connectors 31 are rotatably coupled to their respective pins 42, thereby rotating about the second axis R2. When the contact assembly 100 switches between different circuits, each pair of moving contacts 30 can make stable contact with a corresponding pair of stationary contacts 20, thereby preventing arcing of the contact assembly 100 and helping to improve the service life of the contact assembly 100.

[0071] The following will combine Figure 9 and Figure 10 The principle of the contact assembly 100 according to further embodiments of the present disclosure will be described in detail below. The structure and connection of the contact assembly 100 according to further embodiments will also be described. Figure 7 and Figure 8 Some of the other embodiments described are similar in structure. The differences between them will be described primarily below, while identical parts will not be repeated.

[0072] like Figure 9 and Figure 10 As shown, the contact assembly 100 also includes two covers 80 and two resilient members 60. The two covers 80 are coupled to the first support member 40 at the openings of the two recesses 41, respectively. Each resilient member 60 is located between and coupled to the respective cover 80 and the electrical connector 31. Each resilient member 60 is configured to apply a force to the respective electrical connector 31, causing the electrical connector 31 to abut against the pin 42. With this arrangement, the resilient members 60 increase the rotational damping between the electrical connector 31 and the pin 42, allowing the rotated electrical connector 31 to remain in its current position, thereby ensuring stable contact between a pair of moving contacts 30 and a corresponding pair of stationary contacts 20.

[0073] This disclosure also provides an electrical device. For example... Figure 11 As shown, the electrical equipment includes any of the contact components 100 described above. The circuit of the electrical equipment includes the contact component 100, which controls the on / off state of the circuit. In the contact component 100, even if there is a height difference between the paired stationary contacts 20 during installation, the paired moving contacts 30 can rotate around the second axis R2, thereby abutting against the paired stationary contacts 20 respectively. When the circuit is connected, the paired moving contacts 30 can maintain stable contact with the paired stationary contacts 20, thereby preventing arc erosion of the contact component 100 and helping to improve the service life of the contact component 100.

[0074] In some embodiments, such as Figure 11As shown, the electrical device can be a socket 200. With this arrangement, when the plug is connected to the socket 200, the paired moving contacts 30 of the contact assembly 100 can abut against the paired stationary contacts 20, thereby improving the stability of the circuit connection. As an example, the contact assembly 100 can function as an arc suppressor in the socket 200. When the plug just touches the socket sleeve, the contact assembly 100 disconnects. As the plug continues to be inserted into the socket sleeve, the contact assembly 100 closes, and an arc is generated at the contact assembly 100, not between the plug and the socket 200. When the plug is pulled out, before the plug is separated from the socket sleeve, the contact assembly 100 disconnects, and an arc is generated at the contact assembly 100. When the plug is further pulled out, the circuit is broken, and no arc is generated when the plug separates from the socket sleeve.

[0075] In other embodiments, the electrical device can be a switch. In this way, the contact assembly 100 is disposed on the circuit within the switch, and the contact assembly 100 can improve the stability of the circuit connection within the switch.

[0076] 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.
