Description

Technical Field

[0001] This application belongs to the field of electrical control equipment technology, and specifically relates to a relay. Background Technology

[0002] In related technologies, relays typically include stationary contacts and moving contacts. The stationary contact includes a contact portion with a stationary contact point and a lead-out portion for electrical connection with an external circuit. The moving contact has a moving contact point at the end near the contact portion.

[0003] To save installation space on the relay, the lead-out section is designed to connect to the side of the contact section opposite to the moving contact and extend away from the moving contact. However, this structure increases the overall size of the relay in the direction of the moving contact's extension, thus limiting its application scenarios. Utility Model Content

[0004] This application aims to provide a relay that at least solves the problem that the lead-out portion increases the overall size of the relay in the extension direction of the moving contact, thus limiting its application scenarios.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows: In a first aspect, embodiments of this application provide a relay, the relay comprising: A movable contact has a first end and a second end, and the end of the movable contact near the first end is provided with a movable contact point; A stationary contact includes a contact portion, a lead-out portion, and a connecting portion, wherein the contact portion is provided with a stationary contact corresponding to the moving contact; The connecting portion is connected to the second end of the movable contact on one side. One end of the connecting portion has an inclined section that extends inclinedly from the contact portion toward the second end and in a direction that gradually moves away from the movable contact along the direction of movement of the movable contact. The lead-out portion is connected to the other end of the connecting portion.

[0006] In some embodiments, the relay further includes a moving magnetic element and a stationary magnetic element; The moving magnetic conductor is mounted on the moving contact and located between the first end and the second end. The stationary magnetic conductor is fixed relative to the stationary contact and located on the side of the moving contact facing the stationary contact. The moving magnetic conductor and the stationary magnetic conductor are arranged opposite to each other along a first direction and are adapted to form a magnetic attraction force based on the magnetism generated by the moving contact and / or the stationary contact when a current is passed through the moving contact and the stationary contact, thereby increasing or maintaining the contact pressure between the moving contact and the stationary contact. The first direction is the direction from the stationary contact to the moving contact.

[0007] In some embodiments, the movable contact is provided with a movable contact point at both ends in the extending direction; The moving magnetic conductor is disposed between the two moving contacts, and each moving contact is in a relative position to a stationary contact.

[0008] In some embodiments, the static magnetic component is located on the side of the inclined section away from the contact portion, and the side of the static magnetic component facing the inclined section is configured as an inclined surface or a step shape consistent with the inclined direction of the inclined section.

[0009] In some embodiments, the relay includes a housing, the housing including a first mounting slot and a second mounting slot; The first mounting slot and the second mounting slot are arranged adjacent to each other and separated by a baffle. The static magnetic conductor is embedded in the first mounting slot and the connecting part is embedded in the second mounting slot. The extending direction of the second mounting slot is consistent with the extending direction of the connecting part.

[0010] In some embodiments, the relay further includes a housing having a limit groove; The side wall of the lead-out part is provided with a limiting protrusion, which is inserted into the limiting groove and the two are limited and matched along a first direction, which is the direction from the stationary contact to the moving contact.

[0011] In some embodiments, the inclined segment is located adjacent to or close to the edge of the stationary contact.

[0012] In some embodiments, the orthographic projection of the connection portion of the connecting portion and the contact portion onto the moving contact along a first direction overlaps with the orthographic projection of the edge position of the stationary contact toward the second end onto the moving contact along the first direction, wherein the first direction is the direction from the stationary contact to the moving contact.

[0013] In some embodiments, an inclined extension section extending in the same direction as the inclined section is further provided between the inclined section and the lead-out portion.

[0014] In some embodiments, the relay includes a housing; Both the moving contact and the stationary contact are installed in the housing, and the lead-out portion extends at least partially out of the housing.

[0015] In the embodiments of this application, since the connecting part is connected to the second end of the moving contact on one side, and one end of the connecting part has an inclined section, the inclined section extends obliquely from the contact part toward the second end and gradually away from the moving contact along the direction of movement of the moving contact. The lead-out part is connected to the other end of the connecting part. Therefore, on the one hand, the inclined section allows the lead-out part to be closer to the second end of the moving contact, thereby shortening the distance between the lead-out part and the second end of the moving contact and reducing the space occupied by the lead-out part. On the other hand, the extension direction of the inclined section and the extension direction of the contact part form an angle, reducing the Ampere force generated by the inclined section on the moving contact, thereby reducing the electromagnetic repulsion force of the stationary contact on the moving contact. In summary, the relay provided by the embodiments of this application can reduce the space occupied by the lead-out part, thereby reducing the overall size of the relay, making the relay applicable in scenarios with limited installation space, and making the relay more versatile. At the same time, it can reduce the electromagnetic repulsion force on the moving contact that is opposite to the contact direction of the moving contact, which is beneficial to the stability when the stationary contact and the moving contact are closed, reducing the risk of arcing and explosion when a fault occurs, and improving the safety of the relay.

[0022] Before explaining the relays provided in the embodiments of this application, the application background of the relays provided in the embodiments of this application will be specifically explained: In related technologies, a stationary contact includes a contact portion with a stationary contact and a lead-out portion for electrical connection with an external circuit. A moving contact has a first end and a second end. The end of the first end of the moving contact is provided with a moving contact corresponding to the stationary contact. The lead-out portion is located at the end of the contact portion away from the second end, which increases the distance between the lead-out portion and the lead-out portion corresponding to the second end of the moving contact. That is, the lead-out portion will increase the overall volume of the relay in the extension direction of the moving contact, thereby increasing the required installation space of the relay. This makes the relay unsuitable for scenarios with limited installation space, thus limiting the application scenarios of the relay.

[0023] Based on this, embodiments of this application provide a relay, such as... Figures 1 to 4 As shown, the relay includes: The movable contact 1 has a first end and a second end, and the end of the movable contact 1 near the first end is provided with a movable contact 11.

[0024] The stationary contact 2 includes a contact portion 21, a lead-out portion 22 and a connecting portion 23. The contact portion 21 is provided with a stationary contact 211 corresponding to the moving contact 11.

[0025] The connecting part 23 is connected to the side of the moving contact 1 facing the second end of the connecting part 23. One end of the connecting part 23 has an inclined section 231. The inclined section 231 extends obliquely from the contact part 21 toward the second end and gradually away from the moving contact 1 along the direction of movement of the moving contact 1. The lead-out part 22 is connected to the other end of the connecting part 23.

[0026] As can be seen from the above embodiments, in this embodiment, since the connecting part 23 is connected to the side of the moving contact 1 facing the second end, one end of the connecting part 23 has an inclined section 231. The inclined section 231 extends obliquely from the contact part 21 toward the second end and gradually away from the moving contact 1 along the direction of movement of the moving contact 1. The lead-out part 22 is connected to the other end of the connecting part 23. Therefore, on the one hand, the setting of the inclined section 231 makes the lead-out part 22 closer to the second end of the moving contact 1, thereby shortening the distance between the lead-out part 22 and the second end of the moving contact 1, reducing the space occupied by the lead-out part 22, and reducing the overall volume of the relay. On the other hand, the extension direction of the inclined section and the extension direction of the contact part 21 have an angle, reducing the Ampere force generated by the inclined section 231 on the moving contact 1, thereby reducing the electromagnetic repulsion of the stationary contact 2 on the moving contact 1. In summary, the relay provided in this application embodiment can reduce the space occupied by the lead-out portion 22, thereby reducing the overall size of the relay and enabling it to be used in scenarios with limited installation space, thus making the relay more versatile. Simultaneously, it can reduce the electromagnetic repulsion force on the moving contact 1 that is opposite to the contact direction of the moving contact 11, which is beneficial to the stability of the stationary contact 211 and the moving contact 11 when closed, reducing the risk of arcing or explosion during fault occurrence, and improving the safety of the relay.

[0027] In this embodiment, the first end and the second end of the movable contact 1 are two opposite ends in the extending direction of the movable contact 1. A movable contact 11 can be provided at the end of the movable contact 1 near the first end, or it can be provided at both the end near the first end and the end near the second end. This embodiment does not limit the specific type of movable contact 1. The movable contact 1 can be any structure, such as a plate-like structure, a rod-like structure, or a block-like structure. This embodiment does not limit the specific type of movable contact 1.

[0028] The first ends of the stationary contact 2 and the moving contact 1 are arranged opposite to each other. The stationary contact 2 mainly includes three structural parts: a contact part 21 for setting a stationary contact 211 corresponding to the moving contact 11; a lead-out part 22 for connecting the electrical circuit of an external device; and a connecting part 23 for connecting the contact part 21 and the lead-out part 22. The extension direction of the lead-out part 22 intersects the extension direction of the contact part 21, and the extension direction of the contact part 21 is consistent with the extension direction of the moving contact 1. The stationary contact 2 can be any structure such as a plate-like structure, a rod-like structure, or a block-like structure. The stationary contact 211 and the moving contact 11 can be any of the structural forms such as a wedge-shaped contact, a bridge-type contact, a sliding finger-type contact, or a columnar contact. The inclined segment 231 of the connecting part 23 can be one segment or multiple segments, which is not limited in this embodiment. The inclined segment 231 extends obliquely from the contact portion 21 toward the second end and gradually away from the moving contact 1 along the direction of movement of the moving contact 1. It can be understood that there is an angle between the extension direction of the inclined segment 231 and the extension direction of the contact portion 21.

[0029] In some embodiments, the relay further includes a moving magnetic element 4 and a stationary magnetic element 5; the moving magnetic element 4 is mounted on the moving contact 1 and located between the first end and the second end, the stationary magnetic element 5 is fixed relative to the stationary contact 2 and located on the side of the moving contact 1 facing the stationary contact 2, the moving magnetic element 4 and the stationary magnetic element 5 are arranged opposite to each other along a first direction, and are adapted to form a magnetic attraction force based on the magnetism generated by the moving contact 1 and / or the stationary contact 2 when a current is passed through the moving contact 1 and the stationary contact 2, thereby increasing or maintaining the contact pressure between the moving contact 1 and the stationary contact 2, wherein the first direction is the direction in which the stationary contact 211 points to the moving contact 11.

[0030] In this embodiment, the current flowing through the moving magnetic element 4 and the stationary magnetic element 5 can generate a magnetic attraction force based on the magnetism produced by at least one of the moving contact 1 and the stationary contact 2, thereby increasing or maintaining the contact pressure between the moving contact 1 and the stationary contact 2. When a fault current occurs, the contact pressure when the moving contact 11 and the stationary contact 2 are closed increases, which is more conducive to the stability of the contact between the moving contact 11 and the stationary contact 211. Since the moving magnetic element 4 is installed on the moving contact 1 and located between the first end and the second end, and the stationary magnetic element 5 is fixed relative to the stationary contact 2 and located on the side of the moving contact 1 facing the stationary contact 2, the moving magnetic element 4 can move with the moving contact 1, thereby reducing the magnetic circuit path and lowering the magnetic resistance. At the same time, the moving magnetic element 4 can be directly integrated on the moving contact 1, thereby simplifying the internal structure of the relay, reducing the number of components installed, and reducing the assembly complexity of the relay.

[0031] In some embodiments, the movable contact 1 is provided with movable contacts 11 at both ends in the extension direction. The number of movable contacts 11 provided at each end can be one or more. The example provided in this embodiment is one. The movable magnetic conductor 4 is disposed between the two movable contacts 11, and each movable contact 11 is in a relative position with a stationary contact 211.

[0032] In this embodiment, since the moving contact 1 is provided with a moving contact 11 at both ends in the extension direction, and each moving contact 11 is in a relative position with a stationary contact 211, the arc is elongated by the electrodynamic repulsion through the interruption of the arc by the two sets of moving contacts 11 and stationary contacts 211, thus accelerating its extinguishing and reducing the arc erosion of the moving contacts 11 and stationary contacts 211, thereby improving the arc extinguishing capability of the relay. At the same time, the cooperation between the two sets of moving contacts 11 and stationary contacts 211 can prevent the safety risk caused by the inability of a single moving contact 11 and stationary contact 211 to disconnect, and can reduce the contact resistance between the moving contacts 11 and stationary contacts 211, reduce the temperature rise, and improve the safety performance of the relay. Since the moving magnetic element 4 is located between the two moving contacts 11, the current can pass through the moving magnetic element 4 and the stationary magnetic element 5 to form a magnetic attraction force based on the magnetism generated by at least one of the moving contacts 1 and the stationary contacts 2, thereby increasing or maintaining the contact pressure between the moving contacts 1 and the stationary contacts 2. When a fault current occurs, the contact pressure when the moving contacts 11 and the stationary contacts 2 are closed increases, which is more conducive to the stability of the contact between the moving contacts 11 and the stationary contacts 211, and does not increase the installation space of the moving magnetic element 4, which is beneficial to the compact design of the relay structure.

[0033] In some embodiments, the side of the static magnetic conductor 5 that is close to the inclined section 231 and away from the contact portion 21 is provided with the side of the static magnetic conductor 5 facing the inclined section 231 as an inclined surface or a step shape that is consistent with the inclined direction of the inclined section 231.

[0034] In this embodiment, the inclined surface or step-shaped structure of the static magnetic conductor 5 facing the inclined section 231 allows the static magnetic conductor 5 to make full use of the installation space around the static contact 2, facilitating the installation of the static magnetic conductor 5. On the other hand, it maximizes the volume of the static magnetic conductor 5, thereby improving the magnetic conductivity of the static magnetic conductor 5 and further enhancing its short-circuit resistance.

[0035] In some embodiments, the relay includes a housing 3, which includes a first mounting groove 31 and a second mounting groove 32. The first mounting groove 31 and the second mounting groove 32 are arranged adjacent to each other and separated by a baffle. A static magnetic component 5 is embedded in the first mounting groove 31, and a connecting portion 23 is embedded in the second mounting groove 32. The extending direction of the second mounting groove 32 is consistent with the extending direction of the connecting portion 23.

[0036] In this embodiment, since the first mounting groove 31 and the second mounting groove 32 are arranged adjacent to each other and separated by a baffle, the static magnetic component 5 is embedded in the first mounting groove 31 and the connecting part 23 is embedded in the second mounting groove 32. Therefore, the connecting part 23 and the static magnetic component 5 can be separated by the baffle, so that the installation of the connecting part 23 and the static magnetic component 5 does not interfere with each other, which makes it easier to install the static magnetic component 5 and the static contact 2 in the housing 3, increases the creepage distance between the two static contacts 2, and improves safety. Meanwhile, since one end of the connecting part 23 has an inclined section 231, which extends inclinedly from the contact part 21 toward the second end and gradually away from the moving contact 1 along the direction of movement of the moving contact 1, the second mounting groove 32 also extends inclinedly from the contact part 21 toward the second end and gradually away from the moving contact 1 along the direction of movement of the moving contact 1. This reduces the space occupied by the second mounting groove 32 in the transverse direction of the housing 3 (in the length direction of the static magnetic component 5), and maximizes the space occupied by the first mounting groove 31 in the transverse direction of the housing 3 (in the length direction of the static magnetic component 5). This not only increases the installation space of the static magnetic component 5, but also maximizes the length of the static magnetic component 5, thereby improving the magnetic conductivity of the static magnetic component 5.

[0037] It should be noted that the shell 3 in this application embodiment can be at least one of a box structure with a single-end opening, a frame structure, or a box structure. The first mounting groove 31 and the second mounting groove 32 can be a groove structure opened on the inner wall of the shell 3, or a cavity structure formed by multiple protrusion structures in the shell 3. This application embodiment does not limit this.

[0038] In some embodiments, the relay further includes a housing 3, which is provided with a limiting groove 33; the side wall of the lead-out portion 22 is provided with a limiting protrusion 221, which is inserted into the limiting groove 33 and the two are limited and cooperated along a first direction, the first direction being the direction from the stationary contact 211 to the moving contact 11.

[0039] In this embodiment, the relay also includes a housing 3, which has a limiting groove 33 and a limiting protrusion 221 on the side wall of the lead-out portion 22. The limiting protrusion 221 is inserted into the limiting groove 33, and the two are mutually limitingly engaged along a first direction, which is the direction from the stationary contact 211 to the moving contact 11. Therefore, the limiting engagement between the limiting protrusion 221 and the limiting groove 33, and the limiting groove 33's restriction of the position of the limiting protrusion 221, can improve the stability of the stationary contact 2 during installation. It should be noted that there can be one or more limiting protrusions 221. The limiting protrusion 221 can be located on the side of the lead-out portion 22 near the second end of the moving contact 1, or it can be located on the side of the lead-out portion 22 away from the second end of the moving contact 1. This embodiment does not limit this.

[0040] In some embodiments, the inclined segment 231 is connected to the contact portion 21 at a position adjacent to or close to the edge of the stationary contact 211.

[0041] In this embodiment, since the position where the inclined section 231 is connected to the contact portion 21 is adjacent to or close to the edge of the stationary contact 211, the size of the contact portion 21 in the extending direction can be reduced, that is, the size of the part of the contact portion 21 and the moving contact 1 with opposite currents is reduced, thereby reducing the Ampere force generated by the contact portion 21 on the moving contact 1 that is detrimental to contact, and further improving the stability when the moving contact 1 contacts the stationary contact 2.

[0042] In some embodiments, the orthographic projection of the connection portion 23 on the moving contact 1 along the first direction of the connection portion 23 and the orthographic projection of the edge position of the stationary contact 211 toward the second end on the moving contact 1 along the first direction overlaps, wherein the first direction is the direction in which the stationary contact 211 points to the moving contact 11.

[0043] In this embodiment, since the orthographic projection of the connection portion 23 along the first direction on the moving contact 1 and the orthographic projection of the edge position of the stationary contact 211 towards the second end along the first direction on the moving contact 1 overlap, where the first direction is the direction from the stationary contact 211 to the moving contact 11, the dimension in the extension direction of the contact is minimized, that is, the dimension of the portion of the contact portion 21 and the moving contact 1 with opposite currents is minimized. According to the above embodiment, when the dimension in the extension direction of the contact portion 21 is minimized, it is equivalent to minimizing the effective length of the conductor (the length of the conductor perpendicular to the magnetic field direction in the magnetic field), thereby minimizing the Ampere force generated by the current flowing through the contact portion 21 on the moving contact 1, and further ensuring that the electromagnetic repulsion force on the moving contact 1 opposite to the contact direction of the moving contact 1 is minimized.

[0044] In some embodiments, the inclined extension section extending in the same direction as the inclined section 231 is further provided between the inclined section 231 and the lead-out portion 22.

[0045] In this embodiment, since there is an inclined extension section that extends in the same direction as the inclined section 231 between the inclined section 231 and the lead-out section 22, the distance between the lead-out section 22 and the second end of the moving contact 1 can be further shortened through the inclined extension section, thereby further reducing the space occupied by the lead-out section 22 and further expanding the spatial attributes of the relay. At the same time, the inclined extension section can further save space for the installation of the static magnetic conductor 5 in the housing 3.

[0046] It should be noted that the inclined extension segment can be a single segment or multiple segments, depending on the installation space of the housing 3. This embodiment does not limit this. For example, the inclined extension segment is described as a single segment. An inclined segment 231 and an inclined extension segment are provided between the contact portion 21 and the lead-out portion 22. The inclined segment 231 connects the contact portion 21 and the inclined extension segment, and the inclined extension segment connects the lead-out portion 22 and the inclined segment 231. The angle between the extension direction of the inclined segment 231 and the extension direction of the contact portion 21 is smaller than the angle between the extension direction of the inclined extension segment and the extension direction of the contact portion 21. Given that both the angle between the extension direction of the inclined segment 231 and the extension direction of the contact portion 21 and the angle between the extension direction of the inclined extension segment and the extension direction of the contact portion 21 are obtuse angles, the slope of the inclined segment 231 can be made greater than the slope of the inclined extension segment. This allows the inclined segment 231 to avoid the installation of the static magnetic conductor 5 to the greatest extent possible. Furthermore, the distance between the lead-out portion 22 and the second end of the moving contact 1 can be shortened by the inclined extension segment, further reducing the space occupied by the lead-out portion 22.

[0047] In some embodiments, the relay includes a housing 3, a moving contact 1 and a stationary contact 2, both of which are mounted in the housing 3, and a lead-out portion 22 at least partially extends out of the housing 3. This facilitates electrical connection between the portion of the lead-out portion 22 extending out of the housing 3 and an external circuit, thus simplifying the installation and use of the relay.

[0048] In summary, the relay provided in this application has at least the following beneficial effects: 1. By setting the inclined section 231, the lead-out part 22 can be led out towards the second end of the moving contact 1, thereby shortening the distance between the lead-out part 22 and the second end of the moving contact 1, reducing the space occupied by the lead-out part 22, reducing the overall size of the relay, and making the relay applicable in scenarios with limited installation space, thus making the relay more versatile.

[0049] 2. It can reduce the electromagnetic repulsion force on the moving contact 1 that is opposite to the contact direction of the moving contact 11, which is beneficial to the stability of the stationary contact 211 and the moving contact 11 when they are closed, reduces the risk of disconnection, arcing, and explosion when a fault occurs, and improves the safety of the relay.

[0050] 3. Since one end of the connecting part 23 has an inclined section 231, which extends inclinedly from the contact part 21 toward the second end and gradually away from the moving contact 1 along the direction of movement of the moving contact 1, the second mounting groove 32 also extends inclinedly from the contact part 21 toward the second end and gradually away from the moving contact 1 along the direction of movement of the moving contact 1. This reduces the space occupied by the second mounting groove 32 in the transverse direction of the housing 3 (in the length direction of the static magnetic component 5), and maximizes the space occupied by the first mounting groove 31 in the transverse direction of the housing 3 (in the length direction of the static magnetic component 5). This not only increases the installation space of the static magnetic component 5, but also maximizes the length of the static magnetic component 5, thereby improving the magnetic conductivity of the static magnetic component 5.

[0051] It should be noted that the relays provided in this application embodiment can be used in electrical equipment used for circuit switching, such as household appliances (washing machines, air conditioners, microwave ovens, water meters, etc.), power equipment (high-voltage distribution cabinets, intermediate relays, etc., related equipment used in power systems), and automotive electronic equipment (windshield wipers, oil pumps, air conditioning compressors, etc.). After the relay is used in the relevant electrical equipment, the relevant electrical equipment can also have the beneficial effects of the relay mentioned above. This application embodiment will not elaborate further on this.
