Description

Technical Field

[0001] The present invention relates to the technical field of electrical switches, and in particular to a relay. Background Art

[0002] The magnetic latching relay is a new type of relay developed in recent years. Like other electromagnetic relays, it automatically connects and disconnects circuits. However, the normally closed or normally open state of a magnetic latching relay is entirely dependent on the permanent magnet structure, and the switching state is triggered by a pulsed electrical signal of a certain width.

[0003] In related art, the permanent magnet structure in a magnetic latching relay is a swinging design, meaning the permanent magnet structure is rotatably disposed within a first housing. When a pulse voltage is applied to the electromagnetic structure of the magnetic latching relay, the magnetic field generated by the electromagnetic structure causes the permanent magnet structure to swing, thereby maintaining the magnetic latching relay in a closed or open state. However, the swinging permanent magnet structure results in the magnetic latching relay's opening distance typically being between 1.5mm and 3mm. The rated voltage on the DC side of a charging pile requires 1000VDC, and the impulse withstand voltage is limited to 6kV. The minimum electrical clearance corresponding to the 6kV impulse withstand voltage is 5.5mm, making it difficult for magnetic latching relays with a swinging permanent magnet structure to meet the needs of charging piles.

The moving contact structure slides to the first position relative to the first housing, thereby separating the moving contact and the static contact.

[0047] When both first magnetic portions are attracted to the first moving magnetic member, a reverse current flows into the electromagnetic structure, causing the two first magnetic portions and the second moving magnetic member to attract each other. Since the magnetic poles of the first moving magnetic member and the second moving magnetic member are in opposite directions, the two first magnetic portions repel the first moving magnetic member, thereby assisting the attraction of the two first magnetic portions and the second moving magnetic member. The moving contact structure slides to the second position relative to the first housing, causing the moving contact and the static contact to abut against each other.

[0048] Among them, the two first magnetic parts will repel the second moving magnetic part, which can help the two first magnetic parts and the first moving magnetic part to be attracted together. The two first magnetic parts will repel the first moving magnetic part, which can help the two first magnetic parts and the second moving magnetic part to be attracted together, which is beneficial to improving the on-off stability of the relay and increasing the opening distance between the moving contact and the static contact, making the relay suitable for charging piles. In addition, there may be a risk of leakage to the first moving magnetic part when the moving contact and the static contact are against each other and are turned on. The first moving magnetic part and the second moving magnetic part are spaced apart, that is, the first moving magnetic part and the second moving magnetic part do not contact each other, which is beneficial to reducing the risk of the electromagnetic structure, the first moving magnetic part and the second moving magnetic part being turned on in sequence when the two first magnetic parts are attracted to the second moving magnetic part, thereby reducing the risk of leakage to the electromagnetic structure due to the conduction of the moving contact and the static contact, which is beneficial to improving the safety of the relay.

[0076] Reference Figures 1 to 3 As shown, this embodiment provides a relay, which includes a first housing 100 , an electromagnetic structure 200 , a moving contact structure 300 and a static contact 400 .

[0077] The electromagnetic structure 200 and the static contact 400 are both fixed within the first housing 100. The electromagnetic structure 200 is provided with two first magnetic portions 231 spaced apart along a first direction. The movable contact structure 300 is slidably disposed within the first housing 100 along a second direction. The movable contact structure 300 includes a movable contact 310, a first movable magnetic member 320, and a second movable magnetic member 330 spaced apart along the second direction. The magnetic poles of the first movable magnetic member 320 and the second movable magnetic member 330 face opposite directions. The static contact 400 is located on the side of the movable contact structure 300 away from the electromagnetic structure 200. Exemplarily, the first and second directions are arranged at an angle, for example, perpendicular to each other.

[0078] When a forward current flows into the electromagnetic structure 200 , the movable contact structure 300 slides to the first position, the two first magnetic parts 231 are attracted to the first movable magnetic member 320 to form a first magnetic circuit, and the movable contact 310 and the static contact 400 are separated.

[0079] When reverse current flows into the electromagnetic structure 200 , the movable contact structure 300 slides to the second position, the two first magnetic parts 231 are attracted to the second movable magnetic member 330 to form a second magnetic circuit, and the movable contact 310 and the static contact 400 are against each other.

[0080] Exemplarily, the disconnection process of the relay is as follows: when the two first magnetic parts 231 are attracted to the second moving magnetic part 330, a positive current is passed into the electromagnetic structure 200, which will cause the two first magnetic parts 231 and the first moving magnetic part 320 to attract each other, and because the magnetic poles of the first moving magnetic part 320 and the second moving magnetic part 330 are in opposite directions, the two first magnetic parts 231 will repel the second moving magnetic part 330 to assist the attraction of the two first magnetic parts 231 and the first moving magnetic part 320, and the moving contact structure 300 slides to the first position relative to the first shell 100 to separate the moving contact 310 and the static contact 400.

[0081] Exemplarily, the connection process of the relay is as follows: When the two first magnetic parts 231 are attracted to the first moving magnetic part 320, a reverse current is passed into the electromagnetic structure 200, which will cause the two first magnetic parts 231 and the second moving magnetic part 330 to attract each other, and because the magnetic poles of the first moving magnetic part 320 and the second moving magnetic part 330 are in opposite directions, the two first magnetic parts 231 will repel the first moving magnetic part 320 to assist the attraction of the two first magnetic parts 231 and the second moving magnetic part 330, and the moving contact structure 300 slides to the second position relative to the first shell 100 to cause the moving contact 310 and the static contact 400 to collide with each other.

[0082] It can be understood that the two first magnetic parts 231 will repel the second moving magnetic part 330, which can help the two first magnetic parts 231 and the first moving magnetic part 320 to be attracted together. The two first magnetic parts 231 will repel the first moving magnetic part 320, which can help the two first magnetic parts 231 and the second moving magnetic part 330 to be attracted together, which is beneficial to improving the on-off stability of the relay, and is beneficial to increasing the opening distance between the moving contact 310 and the static contact 400, so that the relay is suitable for charging piles.

[0083] It is understandable that when the moving contact 310 and the static contact 400 are in contact with each other, there may be a risk of leakage to the first moving magnetic member 320. The first moving magnetic member 320 and the second moving magnetic member 330 are spaced apart, that is, the first moving magnetic member 320 and the second moving magnetic member 330 do not contact each other, which helps to reduce the risk of the electromagnetic structure 200, the first moving magnetic member 320 and the second moving magnetic member 330 being sequentially conductive when the two first magnetic parts 231 and the second moving magnetic member 330 are attracted. This further reduces the risk of the moving contact 310 and the static contact 400 being conductive and leaking to the electromagnetic structure 200, which helps to improve the safety of the relay. In some embodiments, the moving contact 310 and the static contact 400 are connected to a high-voltage circuit, while the electromagnetic structure 200 is connected to a low-voltage circuit. If the moving contact 310 and the static contact 400 are conductive and leakage to the electromagnetic structure 200 causes damage to the electromagnetic structure 200.

[0084] In this embodiment, referring to Figure 3 and Figure 4 As shown, the first housing 100 includes a housing body 110 and a cover 120. The first housing body 110 defines a housing cavity 101. The cover 120 covers the opening of the housing cavity 101 to facilitate assembly of the relay. The electromagnetic structure 200, the movable contact structure 300, and the static contact 400 are all disposed within the housing cavity 101.

[0085] In this embodiment, referring to Figure 1 and Figure 2 As shown, the first moving magnetic component 320 includes a first permanent magnet 321 and two first armatures 322. The first permanent magnet 321 has two ends connected in a one-to-one relationship with the two first armatures 322 along the first direction. The second moving magnetic component 330 includes a second permanent magnet 331 and two second armatures 332. The second permanent magnet 331 has two ends connected in a one-to-one relationship with the two second armatures 332 along the first direction, and the magnetic poles of the first permanent magnet 321 and the second permanent magnet 331 face opposite directions. The first magnetic portion 231, the first armature 322, and the second armature 332 are arranged in a one-to-one relationship, with the first magnetic portion 231 positioned between the corresponding first armature 322 and the second armature 332 along the second direction. In this embodiment, when a forward current flows through the electromagnetic structure 200, the first magnetic portion 231 attracts the corresponding first armature 322. When a reverse current flows through the electromagnetic structure 200, the first magnetic portion 231 attracts the corresponding second armature 332.

[0086] It is understandable that when the first magnetic portion 231 attracts the corresponding first armature 322, the internal magnetic flux of the first permanent magnet block 321 flows from the S pole to the N pole, and then flows to the first armature 322 connected to the N pole of the first permanent magnet block 321, the electromagnetic structure 200, and the first armature 322 connected to the S pole of the first permanent magnet block 321 to form a first magnetic circuit. The first magnetic circuit can be composed of Figure 1 The dashed line in FIG. The south pole of the first permanent magnet 321 is set to the first end of the first permanent magnet 321, and the north pole of the first permanent magnet 321 is set to the second end of the first permanent magnet 321. When a reverse current flows through the electromagnetic structure 200, the electromagnetic structure 200 generates a magnetic field that is opposite in direction to the internal magnetic flux lines of the first permanent magnet 321 and aligned in direction with the internal magnetic flux lines of the second permanent magnet 331. The first magnetic portion 231 repels the first armature 322 and engages with the second armature 332, thereby achieving stable and reliable connection of the relay.

[0087] It is understandable that when the first magnetic part 231 attracts the corresponding second armature 332, the internal magnetic flux of the second permanent magnet block 331 flows from the S pole to the N pole, and then flows to the second armature 332 connected to the N pole of the second permanent magnet block 331, the electromagnetic structure 200, and the second armature 332 connected to the S pole of the second permanent magnet block 331 to form a second magnetic circuit. The first magnetic circuit can be composed of Figure 2 The dotted line in the figure indicates that the north pole of the second permanent magnet 331 is set to the first end of the first permanent magnet 321, the south pole of the first permanent magnet 321 is set to the second end of the first permanent magnet 321, the first end of the first permanent magnet 321 and the first end of the second permanent magnet 331 are located on the same side, and the second end of the first permanent magnet 321 and the second end of the second permanent magnet 331 are located on the same side. At this time, a positive current is applied to the electromagnetic structure 200, and the electromagnetic structure 200 generates a magnetic field with a direction opposite to the internal magnetic flux lines of the second permanent magnet 331, and the direction of this magnetic field is the same as the internal magnetic flux lines of the first permanent magnet 321. The first magnetic portion 231 repels the second armature 332 and attracts the first armature 322, thereby achieving stable and reliable connection of the relay.

[0088] In this embodiment, referring to Figure 1 、 Figures 5 to 8 As shown, the shape of the first permanent magnet block 321 includes but is not limited to a prism, a cylinder or a U-shape. The prism shape includes but is not limited to a cuboid or a hexagonal prism.

[0089] In a feasible embodiment, the first permanent magnet 321 is configured as a U-shape, the first armature 322 is configured as a flat plate, and the two ends of the first permanent magnet 321 are respectively fitted with one side surface of the corresponding first armature 322. For example, the first moving magnet 320 is in the shape of a Chinese numeral "X".

[0090] In one feasible embodiment, the first permanent magnet 321 is configured in a prismatic or cylindrical shape, and the first armature 322 includes a first plate portion 3221 and a second plate portion 3222 arranged at an angle. The first permanent magnet 321 is clamped between the first plate portions 3221 of the two first armatures 322, and the first armature 322 can be attracted to the corresponding first magnetic portion 231 through the second plate portion 3222. The second plate portion 3222 extends in a direction away from the first permanent magnet 321. For example, the first moving magnetic member 320 is in the shape of a Chinese character "X".

[0091] Exemplarily, the first plate portion 3221 and the second plate portion 3222 are perpendicular to each other.

[0092] In some embodiments, as Figure 8 As shown, a first slot 3223 is provided at one end of the first armature 322, and both ends of the first permanent magnet 321 are respectively inserted into the corresponding first slots 3223 of the first armature 322, which helps to improve the connection stability between the first armature 322 and the first permanent magnet 321. For example, to facilitate the formation of the first slot 3223, the first armature 322 can be formed by bending a plate. For example, the first armature 322 includes a first plate segment 3224, a second plate segment 3225, a third plate segment 3226, and a fourth plate segment 3227 that are bent in sequence. The first plate segment 3224, the second plate segment 3225, and the fourth plate segment 3227 are parallel to each other, and the second plate segment 3225 and the third plate segment 3226 are perpendicular to each other. The first slot 3223 is formed by the first plate segment 3224, the third plate segment 3226, and the fourth plate segment 3227. The second plate segment 3225 is used to be attracted to the first magnetic portion 231. For example, the first moving magnetic member 320 is in the shape of a Chinese character "X". In this embodiment, the first permanent magnet block 321 is configured as a prism or a cylinder. Of course, in this embodiment, the first permanent magnet block 321 can also be configured as a U-shape or other shapes, which is not limited in this embodiment.

[0093] It can be understood that the first moving magnetic member 320 is in the shape of a "F" character, which is beneficial to increasing the distance between the part where the first armature 322 and the first magnetic part 231 are attracted and the part where the second armature 332 and the first magnetic part 231 are attracted, thereby helping to increase the opening distance between the moving contact 310 and the static contact 400.

[0094] In this embodiment, referring to Figure 1 、 Figures 5 to 8 As shown, the shape of the second permanent magnet block 331 includes but is not limited to a prism, a cylinder or a U-shape.

[0095] In a feasible embodiment, the second permanent magnet 331 is configured as a U-shape, the second armature 332 is configured as a flat plate, and the two ends of the second permanent magnet 331 are respectively fitted with one side surface of the corresponding second armature 332. For example, the second moving magnet 330 is in the shape of a Chinese numeral "X".

[0096] In a feasible implementation, the second permanent magnet block 331 is provided as a prism or a cylinder. The second armature 332 includes a third plate portion 3321 and a fourth plate portion 3322 arranged at an angle. The second permanent magnet block 331 is clamped between the third plate portions 3321 of two second armatures 332, and the second armature 332 can be attracted to the corresponding first magnetic portion 231 through the fourth plate portion 3322. Exemplarily, the fourth plate portion 3322 extends in a direction away from the second permanent magnet block 331. Exemplarily, the second moving magnetic member 330 is in a shape of a capital letter "L".

[0097] Exemplarily, the third plate portion 3321 and the fourth plate portion 3322 are perpendicular to each other.

[0098] In some embodiments, as Figure 8 shown, one end of the second armature 332 is provided with a second slot 3323, and both ends of the second permanent magnet block 331 are respectively inserted into the second slots 3323 of the corresponding second armatures 332, which is beneficial to improving the connection stability between the second armature 332 and the second permanent magnet block 331. Exemplarily, for the convenience of forming the second slot 3323, the second armature 332 can be formed by bending a plate, and its forming method is the same as that of the first armature 322, which will not be elaborated too much in this embodiment. Exemplarily, the second moving magnetic member 330 is in a shape of a capital letter "L". In this embodiment, the second permanent magnet block 331 is provided as a prism or a cylinder. Of course, in this embodiment, the second permanent magnet block 331 can also be provided as a U shape or other shapes, which is not limited in this embodiment.

[0099] It can be understood that the second moving magnetic member 330 is in a shape of a capital letter "L", which is beneficial to increasing the distance between the part where the first armature 322 is attracted to the first magnetic portion 231 and the part where the second armature 332 is attracted to the first magnetic portion 231, and thus is beneficial to increasing the opening distance between the moving contact 310 and the static contact 400.

[0100] Exemplarily, the first moving magnetic member 320 in the shape of a capital letter "L" is inverted, and the second moving magnetic member 330 in the shape of a capital letter "L" is upright, so as to maximize the distance between the part where the first armature 322 is attracted to the first magnetic portion 231 and the part where the second armature 332 is attracted to the first magnetic portion 231. Among them, the first moving magnetic member 320 and the second moving magnetic member 330 can be provided as two symmetrical structures.

[0101] In this embodiment, referring to Figure 1 、 Figures 9 to 11 shown, the moving contact structure 300 further includes a supporting structure. The moving contact 310, the first moving magnetic member 320 and the second moving magnetic member 330 are all arranged on the supporting structure, which is convenient for assembly. Among them, the supporting structure is slidably connected to the first housing 100.

[0102] In one feasible embodiment, the movable contact structure 300 further includes an insulating support member 340, wherein the insulating support member 340 is part of the support structure. The first movable magnetic member 320 and the second movable magnetic member 330 are embedded in the insulating support member 340 to maintain a stable distance between the first movable magnetic member 320 and the second movable magnetic member 330, thereby reducing the risk of electrical conduction between the first movable magnetic member 320 and the second movable magnetic member 330, and thereby reducing the risk of electrical conduction between the movable contact 310 and the static contact 400 causing leakage to the electromagnetic structure 200. The movable contact 310 is disposed outside the insulating support member 340, thereby reducing the risk of electrical conduction between the first movable magnetic member 320 and the second movable magnetic member 330 and the movable contact 310, and thereby reducing the risk of electrical conduction between the movable contact 310 and the static contact 400 causing leakage to the electromagnetic structure 200. It is understood that the insulating support member 340 is made of an insulating material. Among them, the part of the first moving magnetic member 320 that is attracted to the first magnetic part 231 and the part of the second moving magnetic member 330 that is attracted to the first magnetic part 231 are both protruded from the insulating support member 340, which is beneficial to improving the attraction stability of the first moving magnetic member 320 and the first magnetic part 231, and is beneficial to improving the attraction stability of the second moving magnetic member 330 and the first magnetic part 231.

[0103] Exemplarily, the first permanent magnet block 321 and the second permanent magnet block 331 are both embedded in the insulating support 340 , and the portion where the first armature 322 is attracted to the first magnetic portion 231 and the portion where the second armature 332 is attracted to the first magnetic portion 231 are protruded from the insulating support 340 .

[0104] In one feasible embodiment, the movable contact structure 300 further includes a contact support 350 and an elastic member 360, wherein the contact support 350 is part of the support structure. The contact support 350 is connected to the insulating support 340, and the movable contact 310 and the elastic member 360 are both disposed between the insulating support 340 and the contact support 350. The elastic member 360 can press the movable contact 310 against the contact support 350, facilitating assembly. In this embodiment, the elastic member 360 can cushion the impact between the movable contact 310 and the stationary contact 400, thereby improving the service life of the relay.

[0105] Exemplarily, the contact support 350 may be made of metal.

[0106] Exemplarily, the elastic member 360 may be configured as a spring.

[0107] For example, the movable contact 310 can be configured as a bridge structure, that is, the movable contact 310 has two movable contacts 311. The relay includes two stationary contacts 400, each having a stationary contact 410. The two movable contacts 311 are arranged in a one-to-one correspondence with the two stationary contacts 410. The movable contacts 311 of the movable contact 310 abut or separate from the corresponding stationary contacts 410 of the stationary contact 400 to switch the relay on and off.

[0108] In one feasible embodiment, a through slot 370 is formed between the contact support 350 and the insulating support 340. The movable contact 310 is inserted into the through slot 370. The elastic member 360 is disposed within the through slot 370. The first end of the elastic member 360 abuts against the insulating support 340, and the second end of the elastic member 360 abuts against the movable contact 310. The elastic member 360 can press the movable contact 310 against the contact support 350. The provision of the through slot 370 helps improve the installation stability of the movable contact 310.

[0109] Illustratively, the insulating support member 340 and the contact support member 350 are detachably connected to facilitate assembly of the movable contact structure 300 .

[0110] In one feasible embodiment, the contact support 350 includes two connecting arms 351, which are detachably connected to the insulating support 340. In some embodiments, the dynamic contact structure 300 also includes a snap-on plate 380, which is embedded in the insulating support 340, with both ends of the snap-on plate 380 protruding from the insulating support 340. The two connecting arms 351 snap-on to the ends of the snap-on plate 380 in a one-to-one connection, providing a stable and reliable connection. The snap-on plate 380 can be made of metal, which has good structural strength and stability. The connecting arms 351 are provided with a slot that snaps into the snap-on plate 380.

[0111] Exemplarily, the clamping plate 380 is located on the side of the second moving magnetic part 330 away from the first moving magnetic part 320, and the clamping plate 380 is spaced apart from the first moving magnetic part 320, that is, the clamping plate 380 does not contact the first moving magnetic part 320, which helps to reduce the risk of the contact support 350 being conductive with the first moving magnetic part 320 through the clamping plate 380, thereby reducing the risk of the moving contact 310 and the static contact 400 being conductive and leaking electricity to the electromagnetic structure 200.

[0112] In one possible implementation, Figure 3 、 Figure 10 and Figure 11As shown, the contact support member 350 includes a top plate 352, with first protrusions 353 provided on both sides of the top plate 352 along the third direction. The dynamic contact structure 300 also includes two sliding caps 390. Two first sliding grooves 102 are provided in the first housing 100. The first protrusions 353, the sliding caps 390, and the first sliding grooves 102 are provided in a one-to-one correspondence. The sliding caps 390 are mounted on the corresponding first protrusions 353 and slide within the corresponding first sliding grooves 102, which helps improve the sliding stability of the dynamic contact structure 300. The first direction, the second direction, and the third direction can be perpendicular to each other. The provision of the first protrusions 353 facilitates the molding of the contact support member 350 and the installation of the sliding caps 390.

[0113] Exemplarily, one first sliding groove 102 is provided on the shell body 110 , and another first sliding groove 102 is provided on the cover plate 120 .

[0114] In this embodiment, the two connecting arms 351 are connected to opposite sides of the top plate 352 in a one-to-one correspondence. The contact support 350 can be formed by bending, such as by stamping. It will be appreciated that the through slot 370 is formed on the inner side of the top plate 352 and the two connecting arms 351. The elastic member 360 can press the movable contact 310 against the inner side of the top plate 352.

[0115] Illustratively, a through hole 3511 is provided on the connecting arm 351 , and the through hole 3511 extends to the top plate 352 . A protrusion is provided on the hole wall of the through hole 3511 on the top plate 352 to facilitate the molding of the contact support 350 .

[0116] For example, a convex bump 3512 is provided on the outer side of the connecting arm 351. The convex bump 3512 can abut against the first housing 100, thereby improving the sliding stability of the dynamic contact structure 300 and effectively reducing the risk of separation between the insulating support member 340 and the contact support member 350. Of course, the convex bump 3512 and the first housing 100 can also be clearance-fitted to reduce the effect of friction on the sliding of the dynamic contact structure 300. The clearance between the convex bump 3512 and the first housing 100 is less than or equal to 2 mm, for example, 0.5 mm, 1 mm, or 1.5 mm.

[0117] In one possible implementation, Figure 10 and Figure 11 As shown, the insulating support 340 is provided with a second protrusion 341 on both sides along the third direction, and two second slide grooves 103 are provided in the first shell 100. The second protrusion 341 and the second slide groove 103 are arranged in a one-to-one correspondence, and the second protrusion 341 is slidably arranged in the corresponding second slide groove 103, which is beneficial to improving the sliding stability of the dynamic touch structure 300.

[0118] Exemplarily, one second sliding groove 103 is provided on the shell body 110 , and another second sliding groove 103 is provided on the cover plate 120 .

[0119] Exemplarily, two first protrusions (not shown) are protruded from the shell body 110 , and a second sliding groove 103 is formed between the two first protrusions.

[0120] Exemplarily, two second protrusions (not shown) are protruding from the cover plate 120 , and a second sliding groove 103 is formed between the two second protrusions.

[0121] In one possible implementation, Figure 10 As shown, the insulating support member 340 is further provided with two protrusions 342 on both sides along the third direction, and the protrusions 342 are in sliding contact with the first shell 100. The second protrusion 341 is located between the two protrusions 342 along the first direction. The periphery of the protrusion 342 can be in an arc shape.

[0122] In this embodiment, referring to Figure 12 As shown, the electromagnetic structure 200 includes a coil 210, a static iron core 220, and a magnetic yoke 230. The static iron core 220 is inserted into the coil 210, and two magnetic yokes 230 are provided. The yokes 230 include a first magnetic portion 231 and a second magnetic portion 232 arranged at an angle. The second magnetic portions 232 of the two yokes 230 are connected to the ends of the static iron core 220 in a one-to-one correspondence. In this embodiment, when a positive current flows through the coil 210, the magnetic field generated by the electromagnetic structure 200 causes the first magnetic portion 231 to magnetically attract the first moving magnetic member 320 and repel the second moving magnetic member 330. When a reverse current flows through the coil 210, the magnetic field generated by the electromagnetic structure 200 causes the first magnetic portion 231 to magnetically repel the first moving magnetic member 320 and magnetically attract the second moving magnetic member 330, providing stability and reliability. The yoke 230 includes a first magnetic portion 231 and a second magnetic portion 232 arranged at an angle, which helps improve the structural compactness of the relay. The coil 210 may be electrically connected to an external power source via a lead-out pin 211 , and the external power source is used to supply power to the coil 210 .

[0123] Exemplarily, the first magnetic portion 231 and the second magnetic portion 232 are perpendicular to each other.

[0124] Exemplarily, the electromagnetic structure 200 further includes a base 240 , and the yoke 230 and the coil 210 are both disposed on the base 240 . It is understandable that the electromagnetic structure 200 is fixed in the first housing 100 via the base 240 .

[0125] In this embodiment, referring to Figure 3As shown, the relay further includes an arc extinguishing member 500, which is disposed within the first housing 100 and is located on the side of the static contact 400 facing the movable contact 310. In this embodiment, the arc extinguishing member 500 can lengthen the arc generated when the static contact 400 and the movable contact 310 are opened or closed, thereby facilitating the extinguishing of the arc.

[0126] Exemplarily, the arc extinguishing member 500 may be made of magnetic steel.

[0127] Exemplarily, two arc extinguishing members 500 are provided at intervals along the first direction, and the moving contact 310 is located between the two arc extinguishing members 500 along the first direction.

[0128] Exemplarily, a mounting groove 104 for accommodating the arc-extinguishing member 500 is provided in the first housing 100 , for example, the housing body 110 is provided with the mounting groove 104 .

[0129] In this embodiment, referring to Figure 3 and Figure 9 As shown, the relay further includes a first contact 610, a second contact 620, and a first elastic piece 630. The first contact 610 and the second contact 620 are both fixed to the first housing 100, and the first elastic piece 630 is connected to the second contact 620. The first elastic piece 630 is located between the first contact 610 and the first moving magnetic member 320 along the second direction. When the first magnetic portion 231 and the first moving magnetic member 320 are attracted, the first moving magnetic member 320 and the first elastic piece 630 separate, and the first elastic piece 630 separates from the first contact 610. When the first magnetic portion 231 and the second moving magnetic member 330 are attracted, the first moving magnetic member 320, the first elastic piece 630, and the first contact 610 successively abut against each other. In this embodiment, the arrangement of the first contact 610, the second contact 620, and the first elastic piece 630 can expand the functionality of the relay and help improve the applicability of the relay. Furthermore, the first moving magnetic member 320 is spaced apart from the second moving magnetic member 330, thereby reducing the risk that the circuit connected by the first contact 610 and the second contact 620 will be connected to the electromagnetic structure 200 through the first moving magnetic member 320 and the second moving magnetic member 330. In some embodiments, the first contact 610 and the second contact 620 are connected to a high-voltage circuit, while the coil 210 of the electromagnetic structure 200 is connected to a low-voltage circuit. If the first contact 610 and the second contact 620 are connected and current leaks to the electromagnetic structure 200, it may damage the coil 210.

[0130] Exemplarily, the first contact 610 and the second contact 620 are both fixed to the housing body 110 .

[0131] For example, one of the two first armatures 322 is used to push the first elastic piece 630 to contact the first contact 610, which is beneficial to improving the structural compactness of the relay and simplifying the component structure of the relay.

[0132] In one feasible embodiment, when the movable contact structure 300 slides from the first position to the second position, the first elastic piece 630 contacts the first contact 610 before the movable contact 310 contacts the static contact 400. In this embodiment, when the relay is used in the charging circuit of a charging pile, the first circuit containing the first and second contacts 610 and 620 is connected in series with a resistor. The second circuit containing the movable contact 310 and the static contact 400 is connected in parallel with the first circuit and then in series with the charging circuit. The charging circuit refers to the charging loop formed between the charging pile and the battery system. For example, assuming a resistance of 1000 ohms, a resistance of 0.1 ohm after the first and second contacts 610, 620 are conductive, and a resistance of 0.1 ohm after the movable contact 310 and the stationary contact 400 are conductive, based on the principle of series voltage division, assuming the voltage of the charging circuit is V, the voltage u1 after the first and second contacts 610, 620 are conductive is 0.1 / (0.1+1000)V. The load voltage is extremely low, so the resistance helps reduce arcing caused by the opening and closing of the first and second contacts 610, 620. Furthermore, the first elastic piece 630 makes contact with the first contact 610 before the movable contact 310 and the stationary contact 400, i.e., the first circuit is conductive first, followed by the second circuit. Based on the principle of parallel current division, this helps reduce the transient current generated by the closing of the movable and stationary contacts 310, 400, thereby extending their service life.

[0133] In this embodiment, referring to Figure 3 、 Figure 9 and Figure 10 As shown, the relay also includes a third contact 710 and a second elastic piece 720. Two third contacts 710 are provided and fixed to the first housing 100, and the second elastic piece 720 is provided on the movable contact structure 300. When the first magnetic portion 231 and the first moving magnetic member 320 are attracted, the two third contacts 710 are both against the second elastic piece 720; when the first magnetic portion 231 and the second moving magnetic member 330 are attracted, the two third contacts 710 are both separated from the second elastic piece 720. In this embodiment, the provision of the third contact 710 and the second elastic piece 720 can expand the functionality of the relay and help improve the applicability of the relay. The third contact 710 and the second elastic piece 720 can be used to detect the open and closed states of the movable contact 310 and the static contact 400.

[0134] Exemplarily, the third contact 710 is fixed to the housing body 110 .

[0135] Exemplarily, the second elastic piece 720 is disposed on the insulating support member 340 .

[0136] In this embodiment, referring to Figure 9 、 Figure 13 and Figure 14 As shown, the relay further includes a second housing 800 , and the first housing 100 is located in the second housing 800 .

[0137] For example, the first contact 610 and the second contact 620 are sandwiched between the first housing 100 and the second housing 800, and the first elastic piece 630 extends into the first housing 100. The first housing 100 is provided with a first positioning groove for accommodating the first contact 610 and a second positioning groove for accommodating the second contact 620.

[0138] Exemplarily, two third contacts 710 are sandwiched between the first housing 100 and the second housing 800. The third contacts 710 have contact rods 711 that penetrate the first housing 100 and are configured to engage or disengage with the second elastic sheet 720. The first housing 100 includes third positioning slots for accommodating the third contacts 710, with the third contacts 710 corresponding to the third positioning slots.

[0139] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
