Description

Static contact mechanism for switch device and switch device

Technical Field

Example embodiments of the present disclosure relate generally to the field of electrical equipment, and in particular, to a stationary contact mechanism for a switchgear and a switchgear.

Background

More and more switches are now required to control the self-ballasted load of fluorescent lamps, energy-saving lamps, etc. The self-ballasting load is characterized in that the self-ballasting load has larger current at the moment of switching on, and faults such as fusion welding of contacts of a switch and incapability of switching off are easily caused. To solve this problem, the conventional solution is to use a contact that is resistant to fusion welding and to make a means of fixing the stationary contact. If fusion welding still occurs in this case, the contact force of the contact needs to be increased. However, this approach has an adverse effect on the structure and operating feel of the switch, thereby affecting the user experience.

Disclosure of utility model

In a first aspect of the present disclosure, a stationary contact mechanism for a switchgear is provided. The fixed contact mechanism comprises a fixed contact, and is suitable for contacting with a movable contact of the switching device at a closed position to complete a circuit where the switching device is positioned; and an elastic stationary contact including a fixing portion adapted to be electrically connected to a terminal of the switching device to fix the stationary contact mechanism to the terminal, and an elastic deformation portion adapted to be elastically deformed at least in a case where the moving contact is in a closed position, and including: a connecting portion extending from an end of the fixing portion; the bearing part is suitable for bearing the static contact; and a bending portion arranged between the connecting portion and the carrying portion in an extending direction of the elastic stationary contact and arranged to be pressed by the moving contact to allow at least a distance of translation of the carrying portion during movement of the moving contact from the open position to the closed position.

In some embodiments, the bend includes a double bend or an arc bend such that the angle between the connection and the carrier is acute.

In some embodiments, the angle between the connection portion and the fixation portion is less than or equal to 180 ° and greater than 90 ° such that a relief space exists between the connection portion and the housing of the switchgear.

In some embodiments, the elastic stationary contact further comprises: the abutting part is arranged at the free end of the bearing part at a non-zero angle with the bearing part and is abutted with the shell of the switch device at least when the movable contact is at the opening position.

In some embodiments, the angle between the connection portion and the fixation portion is less than or equal to 90 ° such that there is a relief space between the connection portion and the housing of the switching device.

In some embodiments, the elastic stationary contact further comprises: the abutting part is arranged on the side wall of the bearing part at a non-zero angle with the bearing part and is abutted with the shell of the switch device at least when the moving contact is at the opening position.

In some embodiments, the connection portion abuts against a housing of the switching device, and the elastic stationary contact further includes an abutment portion arranged at a free end of the bearing portion at a non-zero angle to the bearing portion, and the free end of the abutment portion abuts against the housing of the switching device such that the bearing portion is maintained at a predetermined distance from the housing.

In some embodiments, the bending angle of the bending portion is equal to or different from the angle between the abutment portion and the bearing portion by less than a threshold value.

In some embodiments, the resilient stationary contact is integrally formed.

In a second aspect of the present disclosure, a switching device is provided. The switching device includes: a housing; a movable contact arranged in the housing, adapted to move between a closed position and an open position; and the stationary contact mechanism described in the first aspect.

By enabling the static contact mechanism to comprise the elastic static contact, the static contact can always keep good contact with the moving contact in the closing process of the moving contact. And because the fixed contact can translate for a certain distance, the energy of the moving contact is absorbed, the bouncing condition of the contact is reduced, and the fusion welding phenomenon is reduced and eliminated. In addition, by adopting the static contact mechanism according to the embodiment of the disclosure, the spring force for driving the movable contact to be closed is not required to be increased additionally, so that contact bounce can be effectively reduced, and fusion welding conditions can be reduced or eliminated. In this way, the contact force of the contact is also reduced, so that the soft operation hand feeling and the silver point collision sound are brought to the customer while the related requirements of the standard are met, and the user experience is improved.

Detailed Description

Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While certain embodiments of the present disclosure have been illustrated in the accompanying drawings, it is to be understood that the present disclosure may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but rather, these embodiments are provided so that this disclosure will be more thorough and complete. It should be understood that the drawings and embodiments of the present disclosure are for illustration purposes only and are not intended to limit the scope of the present disclosure.

It should be noted that any section/subsection headings provided herein are not limiting. Various embodiments are described throughout this document, and any type of embodiment may be included under any section/subsection. Furthermore, the embodiments described in any section/subsection may be combined in any manner with any other embodiment described in the same section/subsection and/or in a different section/subsection.

In describing embodiments of the present disclosure, the term "comprising" and its like should be taken to be open-ended, i.e., including, but not limited to. The term "based on" should be understood as "based at least in part on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The term "some embodiments" should be understood as "at least some embodiments". Other explicit and implicit definitions are also possible below. The terms "first," "second," and the like, may refer to different or the same object. Other explicit and implicit definitions are also possible below.

The foregoing briefly mentions self-ballasted loads such as fluorescent lamps, energy-saving lamps, and the like, which have a large current exceeding the rated current by a factor of even ten or more at the moment of turn-on. In this case, when the switch is controlled to be turned on, the contact of the switch is easily welded, and thus the switch cannot be turned off, and the like, which cannot meet the requirements of some standards about the switch.

In order to solve this problem, the solutions in the conventional solutions include the use of fusion-welding-resistant contacts and the structural provision of fixed contact means. This solution increases the cost of the contacts and also increases the complexity of the switch structure, ultimately resulting in an increase in the cost of the switch. However, in some cases, fusion welding may still occur with modifications in both contact materials and construction. In order to cope with this situation, there is also a solution in which the contact force of the contact is increased.

The contact force of the contact is provided by the spring force of the actuator. To increase the contact force of the contacts, the spring force is correspondingly increased. However, excessive spring force adversely affects both the structure and the operating feel of the switch, thereby affecting the user experience.

Embodiments of the present disclosure provide a stationary contact mechanism for a switchgear and a switchgear to solve the above-mentioned problems or other potential problems found in conventional approaches. The switching device referred to herein is also referred to as a switch and includes a moving contact and a stationary contact mechanism. The movable contact is movable between a closed position and an open position under the control of an actuator (e.g., when a user operates a switch panel). In the closed position, the moving contact is in contact with the stationary contact 101 of the stationary contact mechanism, thereby closing the circuit to achieve energization of the load. In the open position, the moving contact is separated from the stationary contact 101, thereby opening the circuit to de-energize the load.

The inventor has found that the static contact mechanism in the current switch device mostly adopts a rigid element and is rigidly connected with a wiring terminal, and lacks elasticity, so that the problem is caused by contact bounce. The stationary contact mechanism according to the embodiment of the present disclosure has an elastic stationary contact 102 including a fixing portion 1021 and an elastic deformation portion 1022. The elastic deformation portion 1022 has an elastic deformation capability, and also can be elastically deformed with respect to the fixing portion 1021, and has a bent portion 1025, so that the carrying portion 1024 of the elastic stationary contact 102 and the stationary contact 101 thereon are subjected to the pressure of the moving contact during the movement of the moving contact from the open position to the closed position to allow the carrying portion 1024 to translate at least a distance without being deflected substantially or with a small, almost negligible angular deflection. That is, "translation" herein means substantial translation and may include deflection or torsion at a very small, nearly negligible angle (e.g., less than 3 ° or less).

In this way, the stationary contact 101 can always maintain good contact with the moving contact during the closing of the moving contact. And because the fixed contact 101 can translate a distance, the energy of the moving contact is absorbed, the bouncing condition of the contact is reduced, and the fusion welding phenomenon is reduced and eliminated. Furthermore, by employing the stationary contact mechanism according to the embodiments of the present disclosure, it is no longer necessary to additionally increase the spring force for driving the movable contact to close in order to eliminate fusion welding. Therefore, the contact force of the contact is also reduced, so that the requirements of relevant standards are met, meanwhile, a soft operation hand feeling can be brought to a customer, the collision sound of silver points is lightened, and the user experience is improved.

A stationary contact mechanism according to an embodiment of the present disclosure will be described below with reference to fig. 1A to 10. Fig. 1A, 1B, 2A and 2B illustrate simplified schematic diagrams of a stationary contact mechanism according to various embodiments of the present disclosure, wherein a moving contact is not shown, in fig. 2A and 2B, the moving contact is in a closed position. As shown in fig. 1A, 1B, 2A, and 2B, generally, a stationary contact mechanism according to an embodiment of the present disclosure includes an elastic stationary contact 102 and a stationary contact 101. The stationary contact 101, also called stationary contact or silver point, is capable of contacting the moving contact when the moving contact is in the closed position, thereby completing the circuit in which the switching device is located.

As mentioned previously, the elastic stationary contact 102 includes the fixing portion 1021 and the elastically deforming portion 1022. The fixing portion 1021 is electrically connected to the connection terminal 201 of the switching device to fix the elastic stationary contact 102 to the connection terminal 201. For example, the fixing portion 1021 may be a sheet-like structure, and is coupled to the connection wall of the connection terminal 201 in an integrally fitted manner. As the fastener 203 rotates, the wire can be pinched between the fastener 203 and the wire wall to which the fixing portion 1021 is coupled. The fixing portion 1021 may be electrically connected to the connection terminal 201 by any suitable means, including but not limited to: riveting, fastener 203 joining, welding, and the like.

The elastically deforming part 1022 may be made of an elastically deforming material and allows elastic deformation as shown in fig. 2A and 2B to be generated in the case of receiving pressure of the moving contact in the closed position, and returns to the original shape as shown in fig. 1A and 1B in the case of the moving contact in the open position. In fig. 2A and 2B, a broken line indicates an initial position of the elastic deformation portion 1022 in the case where no pressure is applied, and a solid line indicates an engagement position in the case where pressure is applied to the elastic deformation portion 1022. It can be seen that the stationary contact 101 translates a distance during engagement with the moving contact. The whole elastic stationary contact 102 or only the portion of the elastic deformation portion 1022 may be made of a metal material having a certain elastic deformation capability, which is capable of being elastically deformed under the pressure of the moving contact. In some embodiments, the elastically deformable portion 1022 and the fixing portion 1021 (i.e., the entire elastic stationary contact 102) may be integrally formed of an elastically deformable material.

The elastically deforming part 1022 includes a connecting part 1023, a bearing part 1024, and a bending part 1025. The connection portion 1023 is coupled to the fixing portion 1021, i.e., the connection portion 1023 extends outwardly from an end of the fixing portion 1021. The structure and connection of the connection 1023, the carrier 1024 and the bent 1025 of the elastically deformable portion 1022 may be adaptively adjusted according to the structure of the coupled housing 202, which will be further described with reference to the accompanying drawings.

The bearing 1024 bears the stationary contact 101. That is, the stationary contact 101 is mounted on the carrier 1024. The bending portion 1025 is disposed between the connecting portion 1023 and the carrying portion 1024 in the extending direction of the elastic stationary contact 102. By providing the bent portion 1025, the carrier 1024, and thus the entire elastically deformable portion 1022, is subjected to the pressure of the moving contact during the movement of the moving contact from the open position to the closed position, allowing at least a translation of the carrier 1024 by a distance.

In this way, the translation of the bearing 1024 for bearing the fixed contact 101 absorbs the energy of the moving contact, reducing the bouncing of the moving contact and thus reducing the risk of fusion welding of the moving contact and the fixed contact 101 when in contact. In addition, the fixed contact mechanism can ensure effective contact between the movable contact and the fixed contact 101 without large spring force, so that the contact force of the contact is reduced, thereby meeting the related requirements of standards, simultaneously bringing soft operation handfeel to customers and reducing silver point collision sound, and improving user experience.

An exemplary structure when the stationary contact mechanism according to the embodiment of the present disclosure is arranged in a switching device having different housing structures will be described below with reference to fig. 3 to 10. It should be understood that the illustrated cases of fig. 3-10, which will be described below, are not exhaustive, and that stationary contact mechanisms according to embodiments of the present disclosure may include any other suitable structure or shape in addition to these examples.

The structure shown in fig. 3-4 is similar to the structure of the stationary contact mechanism in the simplified schematic of fig. 1A and 2A, except that the structure of the bent portion 1025 is somewhat different. That is, in some embodiments, the bending portion 1025 includes a double bending structure (as shown in fig. 1A-2B) or an arc bending structure (as shown in fig. 3 and 4), such that the angle between the connecting portion 1023 and the carrying portion 1024 is acute. In other words, the elastically deforming part 1022 has an inverted V-shaped structure as a whole.

As shown in fig. 1A to 2B, the double bending structure, that is, from the end of the connection portion 1023 to the end of the bearing portion 1024, is implemented by two bending structures, and each bending angle is substantially greater than or equal to 90 °, but not too large, for example, not greater than 120 °, and the bending angles of the two bending may be different or the same. The disclosed embodiments do not limit the angle of the two bends of the dual bend structure, and any suitable bend angle is possible as long as it can accommodate the shape of the housing 202.

As shown in fig. 3 and fig. 4, the arc-shaped bending structure is actually a deformation of the double bending structure, and the two bending structures are bent in a manner of excessive fillets, so that the production and the manufacturing are more convenient. Of course, in some embodiments, the curved bending structure may also be regarded as having only one rounded bending structure between the connecting portion 1023 and the carrying portion 1024, so that an acute angle is formed therebetween.

The acute angle between the connection portion 1023 and the bearing portion 1024 is set so that the contact area of the stationary contact 101 on the bearing portion 1024 with the movable contact of the movable contact in the closed position is maximized, thereby ensuring the electrical connection quality.

In some embodiments, as shown in fig. 1A, 2A, 3 and 4, the angle between the connecting portion 1023 and the fixing portion 1021 is less than 180 ° and greater than 90 ° such that the connecting portion 1023 makes a non-zero angle with the housing 202 of the switchgear, thereby forming a relief space therebetween. In this way, the connecting portion 1023 is allowed to tilt at an acute angle with respect to the housing 202 adjacent thereto, thereby avoiding the housing 202. By this arrangement, when receiving the pressure of the moving contact in the closed position, the connecting portion 1023 can deflect towards the housing 202, thereby facilitating the translational movement of the carrying portion 1024, and further ensuring that the moving contact and the fixed contact 101 can both maintain good contact during the closing process.

In some alternative embodiments, as shown in fig. 1B and 2B, the angle between the connecting portion 1023 and the fixing portion 1021 may also be 180 ° (also referred to as 0 °), and the relief space between the connecting portion 1023 and the adjacent housing is formed by the housing 202 being recessed or bent inward. In this way, under the pressure of the moving contact when closed, the connection portion 1023 is avoided toward the concave portion or the bending portion of the housing, so as to facilitate the translational movement of the bearing portion 1024.

In some embodiments, to ensure positioning of the resilient stationary contact 102 and its resilient deformation 1022 in the housing 202, the resilient stationary contact 102 may further include an abutment 1026. In the embodiment shown in fig. 1A to 4, the abutment 1026 is arranged at a non-zero angle to the carrier 1024 at a free end of the carrier 1024 to abut the housing 202 of the switching device at least when the moving contact is in the open position. In this way, the position of the bearing 1024 with respect to the housing 202 and thus the positional relationship between the stationary contact 101 and the moving contact that it carries can be ensured.

In order to accommodate the different structures of the housing 202, the positional relationship between the elastically deforming part 1022 and the fixing part 1021 may also take the exemplary form shown in fig. 5 and 6. Fig. 5 illustrates a perspective view of a stationary contact mechanism according to some embodiments of the present disclosure, and fig. 6 illustrates a top view of the stationary contact mechanism illustrated in fig. 5, wherein the general position of the housing 202 is shown simplified. Specifically, in some embodiments, the angle between the connection 1023 and the fixation 1021 is less than 90 ° such that the connection 1023 is at a non-zero angle with the housing 202 of the switchgear. In some alternative embodiments, the angle between the connecting portion 1023 and the fixing portion 1021 may also be equal to 90 °, i.e. the connecting portion 1023 is perpendicular to the fixing portion 1021, and a recess or a bent portion is provided at the housing adjacent to the connecting portion 1023 to provide the above mentioned relief space between the housings adjacent to the connecting portion 1023.

Similar to the case of the elastically deforming portion 1022 shown in fig. 1A to 4 above, when receiving the pressure F of the moving contact in the closed position, as shown in fig. 6, the connecting portion 1023 can deflect toward the housing 202, so as to facilitate the translational movement of the carrying portion 1024 and the fixed contact 101 thereon, and further ensure that the moving contact and the fixed contact 101 can both maintain good contact during the closing process.

In such an embodiment, as shown in fig. 5, the abutment 1026 may be arranged at a non-zero angle to the carrier 1024 at a side wall of the carrier 1024 to abut the housing 202 (not shown in fig. 5) of the switching device at least when the moving contact is in the open position. In this way, the position of the bearing 1024 with respect to the housing 202 and thus the positional relationship between the stationary contact 101 and the moving contact that it carries can be ensured. Of course, it should be understood that in some embodiments, the resilient stationary contact 102 may not include the abutment 1026.

Fig. 7-10 illustrate an exemplary stationary contact mechanism that differs from the structure of the stationary contact mechanism illustrated in fig. 1A-6 to accommodate different housing 202 shapes. Fig. 7 illustrates a perspective view of a stationary contact mechanism according to some embodiments of the present disclosure, and fig. 8 illustrates a side view of the stationary contact mechanism illustrated in fig. 7, wherein the general position of the housing 202 is shown simplified. As shown in fig. 7 and 8, in some embodiments, an end of an abutment 1026 disposed at a free end of the carrier 1024 abuts the housing 202 of the switching device. At the same time, the connection portion 1023 of the elastic stationary contact 102 abuts against the other portion of the housing 202. In this way, the carrier 1024 is kept a predetermined distance from the housing 202.

In such an embodiment, as shown in fig. 8, the bending portion 1025 is implemented with one bending structure. When receiving the contact force F when the moving contact is closed, the bearing portion 1024 can elastically deform relative to the connecting portion 1023 and the abutting portion 1026, so that the angle between the bearing portion 1024 and the connecting portion 1023 (i.e., the angle of the bending portion 1025) and the angle between the bearing portion 1024 and the abutting portion 1026 become large, the bearing portion 1024 translates for a distance, the moving contact 101 and the moving contact are well contacted, and meanwhile, the moving contact can be prevented from bouncing, and further, the fusion welding problem is avoided.

In some embodiments, the bending angle of the bending portion 1025 and the angle between the abutment portion 1026 and the bearing portion 1024 may be equal or the difference between the two angles is smaller than a threshold value, so as to ensure that the forces applied to the bearing portion 1024 in the extending direction are the same, thereby facilitating the translational movement of the bearing portion 1024.

The examples shown in fig. 9 and 10 with respect to the stationary contact mechanism are similar to the examples shown in fig. 7 and 8, except that the stationary contact mechanism is reversed. Similarly, when receiving the contact force F when the moving contact is closed, the bearing portion 1024 can elastically deform relative to the connecting portion 1023 and the abutting portion 1026, so that the angle between the bearing portion 1024 and the connecting portion 1023 (i.e., the angle of the bending portion 1025) and the angle between the bearing portion 1024 and the abutting portion 1026 become large, so that the bearing portion 1024 translates a distance, ensuring good contact between the fixed contact 101 and the moving contact, and avoiding bouncing of the moving contact, and further avoiding occurrence of fusion welding problem.

The foregoing description of implementations of the present disclosure has been provided for illustrative purposes, is not exhaustive, and is not limited to the implementations disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the various implementations described.
