Description

Technical Field

[0001] This utility model relates to a relay assembly, and more specifically, to a relay assembly with a structure that minimizes its size while facilitating physical and electrical integration with other devices. Background Technology

[0002] A relay is a device that operates via an electrical control signal to control the opening and closing of other circuits. The relay is electrically connected to each of these other circuits and to a control power supply that transmits the control signals.

[0003] Relays can be used in any device that needs to allow or cut off power between electrical circuits. As an example, relays can be used in the battery disconnect unit (BDU) of an electric vehicle (EV).

[0004] The BDU is installed between the battery and the inverter. A relay within the BDU is electrically connected to both the battery and the inverter. The relay is configured to enable or disable energizing the connection between the battery and the inverter.

[0005] On the other hand, when relays are installed in electric vehicles, the limited space necessitates miniaturizing both the relay and the BDU (Body Duct Unit) connected to it. This increases the difficulty of physically and electrically connecting the relay and the BDU. Furthermore, with the miniaturization of relays, maintaining their engaged state or energized state with other components becomes more challenging.

[0006] Therefore, there is a need for a solution that can miniaturize relays, easily integrate with other components, and stably maintain the connection and energization state to improve operational reliability.

[0007] Korean Patent Publication No. 10-2022-0155956 discloses a compact automatic power switching device. Specifically, it discloses an automatic power switching device that includes a relay connecting a normal terminal and an emergency terminal to an output terminal, and a PCB on which the relay is mounted. This device can switch the normal terminal and emergency terminal to the output terminal without a circuit breaker, power detection circuit, or CPU control circuit.

[0008] However, the power automatic switching devices disclosed in the existing literature involve mounting the relay on an additional PCB. That is, the existing literature requires an additional process to mount the relay on the PCB, and therefore fails to provide a solution for easily integrating the relay with the PCB.

[0009] Japanese Patent Publication No. 2023-113059 discloses an electrical connection box for vehicles. Specifically, it discloses an electrical connection box for vehicles in which multiple PCB relay modules and plug-in relays are provided, which can suppress the effects of condensation or freezing even when the vehicle is used in cold regions or other environments.

[0010] However, the vehicle electrical connection boxes disclosed in the existing literature only provide a solution to improve the operational reliability of the electrical connection box by using multiple relay modules. That is, the existing literature fails to provide a solution for easily forming and energizing multiple relay modules with other components.

[0063] Reference Figures 1 to 8 The diagram shows the external appearance of a relay assembly 10 according to an embodiment of the present invention. The relay assembly 10 according to this embodiment can be used in conjunction with other devices. In one embodiment, the relay assembly 10 can be used in conjunction with a BDU (Battery Duty Unit) installed in an electric vehicle. In this embodiment, the relay assembly 10 can be electrically connected to another component of the BDU.

[0064] The relay assembly 10 can be configured to enable or disable the electrical connection of the other component. For this purpose, the relay assembly 10 can be operated via control information applied in the BDU. That is, the relay assembly 10 can also be energized with another component that transmits the control information.

[0065] At this time, the relay assembly 10 according to this embodiment of the present invention can be configured to process the received control information and generate control signals. That is, the control information can be directly processed in the relay assembly 10, and the relay assembly 10 can be operated according to the processing result.

[0066] Therefore, the components for processing the control information transmitted to the relay assembly 10 and the work for electrically connecting other components of the relay assembly 10 can be omitted. As a result, the relay assembly 10 and the BDU on which the relay assembly 10 is provided can be miniaturized, while improving assemblability and ease of operation.

[0067] In the illustrated embodiment, the relay assembly 10 includes: a first housing 100, a second housing 200, a control active part 300, an energizing active part 400, and a control module 500.

[0068] The first housing 100 forms part of the outer shape of the relay assembly 10. The first housing 100 is integrated with and supports the other components of the relay assembly 10.

[0069] Furthermore, a space is formed inside the first housing 100, in which a portion of the relay assembly 10 can be accommodated. This space communicates with a space formed inside the second housing 200, thereby allowing or disabling energization between other components of the relay assembly 10 that are energized.

[0070] The first housing 100 is combined with the second housing 200. The first housing 100 is located on one side of the height direction of the relay assembly 10 (on the upper side in the illustrated embodiment) and is combined with the second housing 200 located on the other side of the height direction of the relay assembly 10 (on the lower side in the illustrated embodiment).

[0071] The first housing 100 partially accommodates the control unit 300. That is, as... Figures 6 to 7 As best shown, the first housing 100 accommodates one side (i.e., the upper side) of the shaft member 330 along its length.

When accommodated in the first housing 100, the electrically conductive active part 400 can be electrically connected to other external components. When the electrically conductive active part 400 is working, electric arcs and the like will not leak arbitrarily to the outside due to the action of the first housing 100.

[0073] The first housing 100 is coupled to the control module 500. One side of the first housing 100 in the width direction (the front side in the illustrated embodiment) is coupled to the control module 500.

[0075] The first housing body 110 forms the outer shape of the first housing 100. The first housing body 110 can be combined with or supported by other components of the first housing 100. In the illustrated embodiment, the arc chamber 120 and the magnet component 130 are housed inside the first housing body 110. An insulating plate 140 and a fastening component 150 are arranged on the outside of the first housing body 110.

[0076] The first housing body 110 can be any shape that is combined with or accommodates other components of the first housing 100. In the illustrated embodiment, the first housing body 110 is a three-dimensional graphic shape with a rectangular cross-section and a height in the vertical direction.

[0077] The first housing body 110 can be formed of a lightweight and highly rigid material. Furthermore, the first housing body 110 can be formed of an electrically insulating material. The first housing body 110 is the exposed portion, serving to prevent damage caused by external impacts and to prevent unauthorized external electrical conduction.

[0078] In one embodiment, the first housing body 110 may be formed of a synthetic resin material such as reinforced plastic.

[0079] A space is formed inside the first housing body 110. The arc chamber 120 and the magnet component 130 are accommodated in the space. In addition, an energized movable part 400 and a shaft component 330, which are accommodated in the arc chamber 120, can be arranged in the space of the first housing body 110.

[0080] The arc chamber 120 houses the energized movable part 400. When the fixed contact 410 and the movable contact 420 housed in the arc chamber 120 are separated, the arc generated will not leak arbitrarily to the outside under the action of the arc chamber 120.

[0081] The arc chamber 120 is integrated with the first housing body 110. The arc chamber 120 is located in the space formed inside the first housing body 110. The arc chamber 120 can be supported by one side (the upper side in the illustrated embodiment) of the second housing body 210 in the height direction.

[0082] The arc chamber 120 is combined with the magnet component 130. The electric arc generated in the arc chamber 120 can be guided by the magnetic field formed by the magnet component 130 and extinguished in a desired direction. In the illustrated embodiment, the magnet component 130 is located on the outer side of each side (i.e., left, right, front, and rear) in the length and width directions of the arc chamber 120.

[0083] The arc chamber 120 is combined with the control movement part 300. The arc chamber 120 can support the shaft member 330 of the control movement part 300 so that the shaft member 330 can be raised and lowered.

[0084] The arc chamber 120 is combined with the energized moving part 400. The arc chamber 120 accommodates the energized moving part 400 and can extinguish the arc generated in the energized moving part 400.

[0085] The arc chamber 120 can be any shape that is housed inside the first housing body 110 and can be combined with the magnet member 130, the control actuator 300, and the energizing actuator 400. In the illustrated embodiment, the arc chamber 120 is a three-dimensional shape having a length in the left-right direction, a width in the front-back direction, and a height in the vertical direction. The shape of the arc chamber 120 can be changed accordingly to match the shape of the first housing body 110.

[0086] The arc chamber 120 may be formed of a highly rigid, electrically and thermally insulating material. This is to prevent arc leakage and damage caused by arcing within the energized moving part 400 housed inside the arc chamber 120. In one embodiment, the arc chamber 120 may be formed of a ceramic material.

[0087] An arc chamber space 121 is formed inside the arc chamber 120. The arc chamber space 121 can be defined as the space formed inside the arc chamber 120. The arc chamber space 121 can accommodate a part of the control movement part 300 (i.e., the shaft member 330) so that the shaft member 330 can be raised and lowered.

[0088] Furthermore, the arc chamber space 121 accommodates the energized movable part 400. At this time, a portion of the energized movable part 400 (i.e., the fixed contact 410) can be fixed in the arc chamber space 121. Moreover, other components of the energized movable part 400 (i.e., the movable contact 420) can be located in the arc chamber space 121 in a way that allows them to be raised and lowered together with the shaft member 330.

[0089] The arc chamber space 121 can be a shape corresponding to that of the arc chamber 120. In the illustrated embodiment, the arc chamber space 121 is formed as a three-dimensional shape with a rectangular cross-section and a vertical height.

[0090] The magnet component 130 is combined with the arc chamber 120 to form a magnetic field in the arc chamber space 121. Under the action of the magnetic field formed by the magnet component 130, the electric arc generated in the arc chamber space 121 can be guided in the desired direction and extinguished.

[0091] The magnet component 130 is combined with the arc chamber 120. The magnet component 130 is located outside the arc chamber 120, opposite to the arc chamber space 121.

[0092] Multiple magnet components 130 may be provided.

[0093] The magnet component 130 can be formed in any shape that can generate a magnetic field in the arc chamber space 121. As an example, the magnet component 130 can be formed in the shape of a permanent magnet or an electromagnet.

[0094] The insulating plate 140 physically and electrically separates the plurality of fixed contacts 410 exposed to the outside of the first housing body 110.

The insulating plate 140 is attached to one side (the upper side in the illustrated embodiment) of the first housing body 110 in the height direction. The insulating plate 140 protrudes to the outside of the first housing body 110.

[0096] An insulating plate 140 is located between a plurality of fixed contacts 410. In the illustrated embodiment, the insulating plate 140 is located between a pair of fixed contacts 411, 412 that are spaced apart from each other in the left-right direction. Under the action of the insulating plate 140, the pair of fixed contacts 411, 412 can be physically and electrically separated, thereby preventing arbitrary energization between the pair of fixed contacts 411, 412.

[0097] The insulating plate 140 can be formed in any shape that allows the multiple fixed contacts 410 to be physically and electrically separated. In the illustrated embodiment, the insulating plate 140 is configured as a plate-shaped member having a length in the front-back direction, a height in the vertical direction, and a width in the left-right direction.

[0100] The fastening member 150 engages with a portion of the fixed contact 410 that protrudes outward from the first housing 100 (the upper side in the illustrated embodiment). The fastening member 150 may be engaged through the upper portion of the fixed contact 410. Thus, the upper portion of the fixed contact 410 is exposed to the outside, allowing it to be electrically connected to other components.

[0101] The fastening member 150 can be arranged spaced apart from the sensor terminal 430. That is, as... Figure 3 As best shown, the fastening member 150 can be configured to form a space between itself and the sensor terminal 430.

[0108] Furthermore, a space is formed inside the second housing 200, in which a portion of the relay assembly 10 can be accommodated. This space communicates with a space formed inside the first housing body 110, thereby accommodating the shaft member 330 so that the shaft member 330 can be raised and lowered.

[0109] The second housing 200 is coupled to the first housing 100. The second housing 200 is located on the other side (the lower side in the illustrated embodiment) in the height direction of the relay assembly 10 and supports the first housing 100 located on the upper side.

[0110] The second housing 200 is combined with the control unit 300. The second housing 200 houses the control unit 300. The second housing 200 can accommodate a portion of the control unit 300 so that a portion of the control unit 300 can be raised and lowered.

[0111] Although not shown, a coil (not shown) may be wound on the second housing 200. This coil (not shown) is electrically connected to the control module 500, described later, thereby generating a magnetic field according to a control signal applied by the control module 500. As a result, the fixed core 310 provided in the control movable part 300 is magnetized, thereby causing the movable core 320 and the shaft member 330 coupled thereto to rise.

[0112] The second housing 200 is combined with the control module 500. The second housing 200 can support a portion of the control module 500. The second housing 200 and the control module 500 are electrically connected. The coil (not shown) wound on the second housing 200 can be magnetized by a control power supply applied by the control module 500.

[0113] In the embodiment described, the relay assembly 10 may be configured as an electronic relay.

[0114] Alternatively, the relay assembly 10 may not include the coil (not shown). In the described embodiment, the relay assembly 10 may be configured as a semiconductor relay (SSR, Solid State Relay).

[0115] In the illustrated embodiment, the second housing 200 includes: a second housing body 210, a yoke receiving space 220, a support plate 230, a winding shaft 240, a cylinder component 250, and a control module support protrusion 260.

[0116] The second housing body 210 forms the outer shape of the second housing 200. The second housing body 210 can be combined with or support other components of the second housing 200. In the illustrated embodiment, a yoke receiving space 220 is formed inside the second housing body 210. A support plate 230 is arranged on one side of the second housing body 210 in the height direction (the upper side in the illustrated embodiment). A winding shaft 240 and a cylinder member 250 are formed inside the second housing body 210, and a control module support protrusion 260 is arranged on one side of the second housing body 210 outside (the front side in the illustrated embodiment).

[0117] The second housing body 210 can be any shape that is combined with or accommodates other components of the second housing 200. In the illustrated embodiment, the second housing body 210 is a three-dimensional graphic shape with a rectangular cross-section and a height in the vertical direction.

[0118] The second housing body 210 may be formed of a highly rigid material. This is to stably accommodate or support the relatively heavy control actuator 300 and coil (not shown), and to stably support the first housing 100 and the energized actuator 400 and control module 500 coupled to the first housing 100. In one embodiment, the second housing body 210 may be formed of a metallic material such as aluminum or stainless steel.

[0119] In the illustrated embodiment, the second housing body 210 includes a first surface 211, a second surface 212, and a third surface 213.

[0120] The first surface 211 forms one surface of the second housing body 210. In the illustrated embodiment, the first surface 211 constitutes the other side (i.e., the lower side) of the second housing body 210 in the height direction. The first surface 211 surrounds the yoke receiving space 220 on the other side (i.e., the lower side) in the height direction.

[0121] The first surface 211 may have a shape corresponding to the shape of the cross-section in the horizontal direction of the second housing body 210. In the illustrated embodiment, the first surface 211 is formed as a polygonal plate having a length in the left-right direction, a width in the front-back direction, and a thickness in the vertical direction.

[0122] The first surface 211 is combined with the winding shaft 240 and the cylinder component 250, which are housed in the yoke housing space 220. For example... Figures 6 to 7 As best shown, the lower side of the winding shaft 240 is supported by the first surface 211, and the cylinder member 250 can be connected through the first surface 211.

[0123] The second surface 212 forms the other side of the second housing body 210. In the illustrated embodiment, the second surface 212 constitutes one side (i.e., the left side) of the second housing body 210 in the longitudinal direction. The second surface 212 surrounds the yoke receiving space 220 on the side (i.e., the left side) in the longitudinal direction.

[0124] The second surface 212 may have a shape corresponding to the shape of the cross-section in the vertical direction of the second housing body 210. In the illustrated embodiment, the second surface 212 is formed as a polygonal plate having a length in the vertical direction, a width in the front-back direction, and a thickness in the left-right direction.

[0125] The second surface 212 and the first surface 211 form a defined angle and are continuously formed. In one embodiment, the defined angle may be a right angle. In the illustrated embodiment, one side (i.e., the lower side) of the second surface 212 in the height direction is continuously formed with the left end of the first surface 211. The second surface 212 and the third surface 213 are arranged facing each other across the yoke receiving space 220.

[0126] The third surface 213 forms another side of the second housing body 210. In the illustrated embodiment, the third surface 213 constitutes the other side (i.e., the right side) of the second housing body 210 in the longitudinal direction. The third surface 213 surrounds the yoke receiving space 220 on the other side (i.e., the right side) in the longitudinal direction.

[0127] The third surface 213 may be a shape corresponding to the shape of the cross section in the vertical direction of the second housing body 210 or the shape of the second surface 212. In the illustrated embodiment, the third surface 213 is formed as a polygonal plate having a length in the vertical direction, a width in the front-back direction, and a thickness in the left-right direction.

[0128] The third surface 213 and the first surface 211 form a defined angle and are continuously formed. In one embodiment, the defined angle may be a right angle. In the illustrated embodiment, one side (i.e., the lower side) of the third surface 213 in the height direction is continuously formed with the right end of the first surface 211. The third surface 213 is arranged facing the second surface 212 across the yoke receiving space 220.

[0129] The yoke receiving space 220 is a space formed inside the second housing body 210. The second housing body 210 and the support plate 230 surround the yoke receiving space 220 on each side in the height direction and each side in the length direction. In the illustrated embodiment, the upper, lower, left, and right sides of the yoke receiving space 220 are surrounded by the second housing body 210 and the support plate 230.

[0130] The yoke receiving space 220 is open on each side (front and rear in the illustrated embodiment) in the width direction. Therefore, no additional components are needed to surround the yoke receiving space 220, thereby enabling miniaturization and weight reduction of the relay assembly 10.

[0131] The yoke receiving space 220 accommodates the winding spool 240 and the cylinder member 250. In addition, the yoke receiving space 220 accommodates the coil (not shown) wound on the winding spool 240 and the control movement part 300 accommodated in the cylinder member 250.

[0132] The yoke receiving space 220 can be shaped to correspond to the shape of the second housing body 210. In the illustrated embodiment, the yoke receiving space 220 is formed as a polygonal prism-shaped space with a rectangular cross-section and a height in the vertical direction.

[0133] In the embodiment described, the horizontal length or width of the yoke receiving space 220 can be formed to be greater than or equal to the thickness of the coil (not shown) wound on the winding shaft 240. Thus, the coil (not shown) wound on the winding shaft 240 will not protrude outwards from the yoke receiving space 220.

[0134] The yoke receiving space 220 can communicate with the arc chamber space 121 through the support through hole 231 formed inside the support plate 230. Thus, the shaft member 330 can move up and down within the yoke receiving space 220 and the arc chamber space 121.

[0135] The support plate 230 covers the yoke receiving space 220 on one side (i.e., the upper side) in the height direction. Furthermore, the support plate 230 supports the first housing 100 on the lower side. The support plate 230 is located between the first housing 100 and the second housing body 210.

[0136] The support plate 230 may have a shape corresponding to the cross-sectional shape of the first housing body 110 or the second housing body 210 in the horizontal direction. In the illustrated embodiment, the support plate 230 is configured as a polygonal plate with a rectangular cross-section and a thickness in the vertical direction.

[0137] In the illustrated embodiment, the support plate 230 includes a support through hole 231.

[0138] A through hole 231 is formed inside the support plate 230. The through hole 231 connects the arc chamber space 121 and the internal space of the cylinder component 250. The shaft component 330 housed in the cylinder component 250 can pass through the through hole 231 and move up and down.

[0139] The support through hole 231 can be of any shape capable of connecting the arc chamber space 121 with the internal space of the cylinder member 250. In one embodiment, the support through hole 231 can be a shape corresponding to the cross-sectional shape of the shaft member 330. In the illustrated embodiment, the support through hole 231 is formed as a disk-shaped space with a circular cross-section and a thickness in the vertical direction.

[0140] The through hole 231 is formed with open sides in the thickness direction (upper and lower sides in the illustrated embodiment). The radial direction of the through hole 231 can be surrounded by the inner circumference of the support plate 230. The outer circumference of the shaft member 330 passing through the through hole 231 can be supported by the inner circumference of the support plate 230.

[0141] The winding shaft 240 is the portion for winding the coil (not shown). The winding shaft 240 supports the wound coil (not shown) on its radially inner side. The coil (not shown), while wound on the winding shaft 240, can be electrically connected to the operating terminal 440 and the control module 500, respectively.

[0142] The winding shaft 240 is combined with the second housing body 210. Specifically, as follows: Figures 6 to 7 As best shown, the winding shaft 240 is housed in the yoke housing space 220 and supported by the first surface 211. The second housing body 210 of the winding shaft 240 is surrounded by the second surface 212 and the third surface 213 on each side along its length (left and right sides in the illustrated embodiment).

[0143] The winding shaft 240 is coupled to the support plate 230. One side of the winding shaft 240 in the height direction (the upper side in the illustrated embodiment) supports the support plate 230 on the lower side.

[0144] The winding spool 240 is coupled to the cylinder member 250. A hollow portion is formed through the interior of the winding spool 240. The cylinder member 250 can be accommodated in the hollow portion. The radial direction of the cylinder member 250 can be supported by the winding spool 240.

[0145] The winding shaft 240 can be of any shape for winding the coil (not shown) and for engaging with the cylinder member 250. In the illustrated embodiment, the winding shaft 240 is formed as a three-dimensional shape having a circular cross-section and a height in the vertical direction, with its upper and lower sides extending radially.

[0146] The cylinder assembly 250 houses the control actuator 300. A portion of the control actuator 300 may be fixedly housed in the cylinder assembly 250. Other portions of the control actuator 300 may be vertically or vertically housed in the cylinder assembly 250.

[0147] The cylinder component 250 is connected to the arc chamber space 121. Specifically, the cylinder component 250 is connected to the arc chamber space 121 through a support through hole 231 formed inside the support plate 230.

[0148] The cylinder component 250 is combined with the second housing body 210. Specifically, as follows: Figures 6 to 7 As best shown, the cylinder member 250 is received in the yoke receiving space 220 and is connected through to the first surface 211. One side of the cylinder member 250 in the height direction (the lower end in the illustrated embodiment) may be located outside the first surface 211.

[0149] The cylinder component 250 is combined with the support plate 230. The cylinder component 250 is located below the support plate 230 and can support the support plate 230.

[0150] The cylinder member 250 is coupled to the winding shaft 240. The cylinder member 250 can be accommodated within a hollow portion formed inside the winding shaft 240. That is, the radially outer side of the cylinder member 250 is surrounded by the winding shaft 240, so it does not expose to the outside. The cylinder member 250 is radially supported by the winding shaft 240.

[0151] The cylinder member 250 can be of any shape that accommodates the control movement part 300 and can be supported by the second housing body 210 and the winding shaft 240. In the illustrated embodiment, the cylinder member 250 is formed as a three-dimensional graphic shape with a circular cross-section and a height in the vertical direction.

[0152] The control module support protrusion 260 is a portion for the second housing 200 to engage with the control module 500. The control module support protrusion 260 is configured to support the control module 500, which engages with the electrically connected movable part 400. The control module support protrusion 260 engages with the second housing body 210.

[0153] The control module support protrusion 260 can be configured at a position corresponding to the location of the control module 500. In the illustrated embodiment, the control module support protrusion 260 is located on the upper side in front of the second housing body 210.

[0154] The control module support protrusion 260 can be of any shape capable of supporting the control module 500. In the illustrated embodiment, the control module support protrusion 260 protrudes to one side (i.e., the front side) of the second housing body 210 in the width direction, and the protrusion length on the outer side in the length direction is greater than the protrusion length on the inner side in the length direction.

[0155] That is, when viewed from the horizontal direction, the control module support protrusion 260 is configured as an angle member shape including at least one bend.

[0156] Multiple control module support protrusions 260 can be provided. Multiple control module support protrusions 260 are configured to be spaced apart from each other and can support control modules 500 in different positions.

[0157] In the illustrated embodiment, a pair of control module support protrusions 260 are provided, and are spaced apart along the length direction (i.e., left-right direction) of the second housing body 210. The pair of control module support protrusions 260 can respectively support the lower left and lower right ends of the control body 510. The pair of control module support protrusions 260 are arranged facing each other along the length direction of the second housing body 210, separated by the control module 500.

[0158] The control unit 300 operates according to the control signal applied by the control module 500. The control unit 300 is combined with the energizing unit 400, causing a part of the energizing unit 400 (i.e., the movable contact 420 described later) to move, contacting the fixed contact 410 to energize or separating from the fixed contact 410 to de-energize.

[0159] The control unit 300 is partially located in the first housing 100. Specifically, a portion of the control unit 300 (i.e., the shaft member 330) is at least partially housed inside the arc chamber 120 and is coupled to the movable contact 420.

[0160] The control unit 300 is coupled to the second housing 200. The control unit 300 is housed in a space formed inside the cylinder member 250 and is supported by the cylinder member 250.

[0161] Furthermore, the control unit 300 is arranged adjacent to the coil (not shown) wound on the winding shaft 240. The control unit 300 can be magnetized when the coil (not shown) is energized.

[0162] The control unit 300 is combined with the energized unit 400. The control unit 300 can be combined with the movable contact 420 and move together.

[0163] In the illustrated embodiment, the control movement 300 includes a fixed core 310, a movable core 320, a shaft member 330, and an elastic member 340. Furthermore, although not shown, the control movement 300 may also include the coil (not shown) wound on the winding shaft 240.

[0164] The fixed core 310 is magnetized by the magnetic field generated when the coil (not shown) is energized. The magnetized fixed core 310 applies a magnetic attractive force to the movable core 320. As a result, the movable core 320 and the shaft member 330 connected to it can rise together toward the fixed core 310.

[0165] The fixed core 310 is combined with the cylinder member 250. Specifically, the fixed core 310 is accommodated in the space formed inside the cylinder member 250, and the radial direction of the fixed core 310 can be supported by the cylinder member 250.

[0166] As the name suggests, the fixed core 310 will not move. That is, the fixed core 310 is fixedly engaged with the cylinder member 250 at a predetermined position. Therefore, the magnetic attraction force generated by the fixed core 310 can be used only to move the movable core 320. In the illustrated embodiment, the fixed core 310 is located on one side (i.e., the upper side) of the cylinder member 250 in the height direction.

[0167] The fixed core 310 has a hollow section inside. The shaft member 330 can be vertically and vertically connected through the hollow section.

[0168] The fixed core 310 and the movable core 320 are arranged adjacent to each other. At this time, when the fixed core 310 is not magnetized, the fixed core 310 can be separated from the movable core 320 along its height direction (i.e., the vertical direction).

[0169] That is, such as Figures 6 to 7 As best shown, the fixed core 310 is arranged adjacent to the upper end of the cylinder member 250, such that it is arranged at a predetermined distance from the movable core 320, which is arranged adjacent to the lower end of the cylinder member 250.

[0170] The fixed core 310 is combined with the shaft member 330. The fixed core 310 supports the shaft member 330 so that the shaft member 330 can be raised and lowered.

[0171] The fixed core 310 is elastically supported by the elastic member 340. One side of the fixed core 310 in the height direction (the lower side in the illustrated embodiment) can contact and be supported by one side of the elastic member 340 in the height direction (i.e., the upper side).

[0172] The fixed core 310 can be any shape that can be magnetized by the magnetic field formed by the coil (not shown) and can apply a magnetic attraction force to the movable core 320. In the illustrated embodiment, the fixed core 310 is formed as a three-dimensional shape with a circular cross-section and a height in the vertical direction, and has a hollow part inside.

[0173] The movable core 320 rises using the magnetic attraction formed by the fixed core 310. When the movable core 320 rises, the movable contact 420 connected to it also rises and can contact the fixed contact 410. Thus, the relay assembly 10 can energize external components.

[0174] The movable core 320 is coupled to the cylinder member 250. Specifically, the movable core 320 is vertically and flexibly accommodated in a space formed inside the cylinder member 250. The radially outer side of the movable core 320 can be supported by the cylinder member 250.

[0175] As the name suggests, the movable core 320 is a movable component in the configuration of the control movement part 300. The movable core 320 can move in the direction of the fixed core 310 (i.e., upward) using the magnetic attraction force applied by the fixed core 310. When the magnetization state of the fixed core 310 is demagnetized, the movable core 320 can move in the opposite direction of the fixed core 310 (i.e., downward) using its own weight and the restoring force applied by the elastic member 340.

[0176] The movable core 320 is combined with the shaft member 330. The movable core 320 can rise or fall together with the shaft member 330.

[0177] The movable core 320 is elastically supported by the elastic member 340. One side of the movable core 320 in the height direction (the upper side in the illustrated embodiment) can contact and be supported by the other side (i.e., the lower side) of the elastic member 340 in the height direction.

[0178] The movable core 320 can be of any shape that can rise together with the shaft member 330 toward the fixed core 310 by means of the magnetic attraction applied by the fixed core 310. In the illustrated embodiment, the movable core 320 is formed as a three-dimensional graphic shape with a circular cross-section and a height in the vertical direction.

[0179] The shaft member 330 transmits the movement of the movable core 320 to the energized movable part 400. The shaft member 330 can be engaged with both the movable core 320 and the movable contact 420 of the energized movable part 400 and move together.

[0180] The shaft member 330 is vertically and movably connected to both the first housing 100 and the second housing 200. Specifically, the shaft member 330 is vertically and movably connected to the support through hole 231 formed in the support plate 230.

[0181] A portion of the shaft member 330 located above the supporting through hole 231 is situated in the arc chamber space 121 and engages with the movable contact 420. A portion of the shaft member 330 located below the supporting through hole 231 is situated in the space formed inside the cylinder member 250 and engages with the movable core 320.

[0182] The shaft member 330 can be of any shape that is combined with the movable core 320 and the movable contact 420 respectively and can move up and down together. In the illustrated embodiment, the shaft member 330 is formed as a three-dimensional graphic shape with a circular cross-section and a height in the vertical direction.

[0183] One side of the shaft member 330 in the height direction (the upper end in the illustrated embodiment) engages with the movable contact 420. The other side of the shaft member 330 in the height direction (the lower end in the illustrated embodiment) engages with the movable core 320.

[0184] The shaft member 330 is combined with the elastic member 340. The shaft member 330 passes through the hollow portion formed inside the elastic member 340.

[0185] The elastic member 340 provides a restoring force for the descent of the movable core 320. The elastic member 340 deforms and stores the restoring force when the movable core 320 rises. When the magnetization of the fixed core 310 is de-magnetized, the movable core 320 can descend using the restoring force provided by the elastic member 340 and its own weight, and quickly separate from the fixed core 310.

[0186] The elastic member 340 is located in the space formed inside the cylinder member 250. The elastic member 340 contacts and provides elastic support to both the fixed core 310 and the movable core 320. In the illustrated embodiment, the elastic member 340 is located between the fixed core 310 and the movable core 320, and contacts the lower end of the fixed core 310 and the upper end of the movable core 320, respectively.

[0187] The elastic member 340 is combined with the shaft member 330. The elastic member 340 has a hollow part inside, and the shaft member 330 can be vertically and vertically connected to the hollow part.

[0188] The elastic member 340 can be configured to deform and store restoring force when the movable core 320 rises, and to provide the stored restoring force to the movable core 320 in any form. In the illustrated embodiment, the elastic member 340 is configured as a coil spring with a circular cross-section and a vertical height, and has a hollow section formed inside.

[0189] The energizing unit 400 is a configuration that allows the relay assembly 10 to be energized and connected to other external components. The energizing unit 400 can operate in conjunction with the control unit 300 and enable or disable the energizing state of other external components.

[0190] The energized movable part 400 is coupled to the first housing 100. The energized movable part 400 is housed within the arc chamber space 121 formed inside the arc chamber 120, and at least a portion of the energized movable part 400 protrudes to the outside of the first housing 100. The other external components can be electrically connected to the energized movable part 400 through the portion thereof.

[0191] The energized movable part 400 is combined with the control movable part 300. A portion of the energized movable part 400 (i.e., the movable contact 420 described later) can be combined with the movable core 320 via the shaft member 330 and can move up and down together.

[0192] The energized active unit 400 is integrated with the control module 500. The energized active unit 400 and the control module 500 are electrically connected and can receive control signals for operation. Furthermore, detection information related to the status of the energized active unit 400 can be transmitted to the control module 500.

[0193] In the illustrated embodiment, the energized active part 400 includes: a fixed contact 410, a movable contact 420, a sensor terminal 430, and an operation terminal 440.

[0194] The fixed contact 410 is a configuration in which the energized movable part 400 can be electrically connected to an external configuration. The fixed contact 410 is at least partially exposed on the outside of the first housing 100 and can be electrically connected to the external configuration.

[0195] The fixed contact 410 is coupled to the first housing 100. Specifically, the fixed contact 410 penetrates and is coupled to both the first housing body 110 and the arc chamber 120. One side of the fixed contact 410 along its length (the upper side in the illustrated embodiment) protrudes from the outer side of the first housing body 110. The other side of the fixed contact 410 along its length (the lower side in the illustrated embodiment) is located in the arc chamber space 121 and is in contact with or separate from the movable contact 420.

[0196] The fixed contact 410 contacts the movable contact 420 to energize, or separates from the fixed contact to de-energize. That is, when the movable contact 420 rises along with the movable core 320 and the shaft member 330 connected thereto, the fixed contact 410 can contact the movable contact 420 and energize. Furthermore, when the movable core 320 and the shaft member 330 connected thereto descend, the fixed contact 410 can separate from the movable contact 420 and de-energize.

[0197] As the name suggests, the fixed contact 410 is fixedly attached to the first housing 100. That is, the fixed contact 410 does not move. Therefore, it can be understood that the contact and separation of the fixed contact 410 and the movable contact 420 are achieved by the movement of the movable contact 420.

[0198] The fixed contact 410 is coupled to the sensor terminal 430. The portion of the fixed contact 410 located on the outside of the first housing body 110 is coupled to the sensor terminal 430 for generating detection information related to the temperature of the fixed contact 410.

[0199] The retaining contact 410 is engaged with the fastening member 150. The portion of the retaining contact 410 (i.e., the portion exposed outside the first housing body 110) is engaged with the fastening member 150. As described above, the fastening member 150 is configured to prevent arbitrary movement of the sensor terminal 430. In this case, the outer periphery of the retaining contact 410 may be threaded for engagement with the fastening member 150.

[0200] The fixed contact 410 can be of any shape, engaging with the first housing 100 and contacting or separating from the movable contact 420, and capable of engaging with the sensor terminal 430 and the fastening member 150. In the illustrated embodiment, the fixed contact 410 is formed as a cylinder with a circular cross-section and a height in the vertical direction.

[0201] Multiple fixed contacts 410 may be provided. These fixed contacts 410 are spaced apart from each other and can simultaneously contact or separate from the movable contact 420. In the illustrated embodiment, the fixed contacts 410 are provided as a pair, including a first fixed contact 411 and a second fixed contact 412.

[0202] The first fixed contact 411 is located on one side of the length direction of the first housing 100 (left side in the illustrated embodiment). The first fixed contact 411 is engaged with the first fastening member 151 and the first sensor terminal 431, respectively. The first fixed contact 411 is in contact with or separates from the upper left side of the movable contact 420.

[0203] The second fixed contact 412 is located on the other side of the length direction of the first housing 100 (the right side in the illustrated embodiment). The second fixed contact 412 is engaged with the second fastening member 152 and the second sensor terminal 4320, respectively. The second fixed contact 412 is in contact with or separates from the upper right side of the movable contact 420.

[0204] The insulating plate 140 is located between the first fixed contact 411 and the second fixed contact 412. As described above, the first fixed contact 411 and the second fixed contact 412 can be physically and electrically separated by the insulating plate 140.

[0205] Therefore, it can be understood that the energized state of the first fixed contact 411 and the second fixed contact 412 is formed by the first fixed contact 411 and the second fixed contact 412 simultaneously contacting the movable contact 420.

[0206] The movable contact 420 is connected to the movable core 320 via a shaft member 330. The movable contact 420 can move in response to the movement of the movable core 320, thereby contacting or separating from the fixed contact 410. Thus, the movable contact 420 can be energized or de-energized with the fixed contact 410. Consequently, external components energized to the fixed contact 410 can be energized or de-energized.

[0207] The movable contact 420 is coupled to the first housing 100. Specifically, the movable contact 420 is located in the arc chamber space 121 formed inside the first housing 100. The movable contact 420 can be vertically and vertically positioned in the arc chamber space 121.

[0208] At this time, the movable contact 420 can be surrounded by the arc chamber 120 together with the fixed contact 410. Thus, as described above, arbitrary leakage of the arc generated when the movable contact 420 and the fixed contact 410 are separated can be prevented.

[0209] The movable contact 420 is engaged with the shaft member 330. The movable contact 420 can move together with the shaft member 330 and is supported by the shaft member 330.

[0211] The movable contact 420 can be of any shape capable of simultaneously contacting and energizing multiple fixed contacts 411, 412, or separating and de-energizing them. In the illustrated embodiment, the movable contact 420 is a three-dimensional graphic shape whose length in the left-right direction is greater than its width in the front-back direction, and which has height in the vertical direction. In this case, the length in the left-right direction of the movable contact 420 can be greater than the distance between a pair of fixed contacts 411, 412.

Therefore, the work of combining the configuration for generating control signals with the relay assembly 10 can be omitted, making the process of combining the relay assembly 10 with other external components simpler.

[0230] Furthermore, since the control module 500 is directly installed in the relay assembly 10, the process of generating and transmitting control signals can be performed more quickly compared to the case where the relay assembly 10 is connected to the components used to generate control signals through additional wiring.

[0231] The control module 500 is coupled to the first housing 100 and the second housing 200.

Connector component 520 is located on the side of control body 510 opposite to the first housing 100 or the second housing 200 (front side in the illustrated embodiment). In other words, connector component 520 is located on the outward-facing side of control body 510 in the thickness direction.

[0242] Connector component 520 is arranged adjacent to terminal component 530. A space is formed inside connector component 520 to accommodate terminal component 530. Connector component 520 is configured to surround terminal component 530 on the outside.

[0256] Therefore, according to the relay assembly 10 of this utility model embodiment, when the control module 500 is combined with the main board connector 21, no additional connection process is required for electrical connection with the main board 20.

[0257] Therefore, the process of combining the relay assembly 10 with the main board 20 can be performed in a simple and reliable manner.

[0258] As described above, in the embodiment where the main substrate 20 is a substrate mounted on the BMS, the electrical connection between the BDU and the BMS can be achieved by combining the control module 500 of the relay assembly 10 with the main substrate connector 21.
