Description

Technical Field

[0001] This application relates to the field of relay technology, and more particularly to a relay and an electrical device. Background Technology

[0002] A relay is an electronic control device that has a control system (also known as an input circuit) and a controlled system (also known as an output circuit), and is commonly used in automatic control circuits. Essentially, a relay is an "automatic switch" that uses a smaller current to control a larger current. Therefore, relays play roles in circuits such as automatic adjustment, safety protection, and circuit switching. With the rapid development of the new energy industry, relays are widely used in new energy vehicles and charging equipment, photovoltaic / wind power generation systems, and engineering vehicles.

[0003] Currently, relays on the market typically require both a stationary contact structure and auxiliary contact functionality. However, in related technologies, the structural design of relays with auxiliary contacts cannot guarantee the insulation withstand voltage level around the stationary contact structure, making the stationary contact structure more susceptible to current breakdown under load. Utility Model Content

[0004] This application provides a relay and electrical equipment that can ensure that an insulation withstand voltage level is formed around the stationary contact structure, thereby avoiding or mitigating the technical problem of the stationary contact structure being broken down by current when subjected to load.

[0005] A first aspect of this application provides a relay, the relay comprising:

[0006] Main housing, the main housing

[0007] The top has a first opening and a fourth opening;

[0008] A terminal block, wherein the terminal block has a second opening and a fifth opening;

[0009] A static contact structure, wherein one end of the static contact structure is installed in the first opening, and the other end of the static contact structure passes through the second opening;

[0010] An extension probe is provided, with one end of the extension probe installed in the fourth opening and the other end of the extension probe passing through the fifth opening;

[0011] And an insulating component, which is located between the main housing and the terminal block; the insulating component has a third opening for the static contact structure to pass through and a sixth opening for the lead-out probe to pass through.

[0012] In this embodiment, an insulating component is provided between the main housing and the terminal block. This component isolates the main housing from the terminal block. Furthermore, the insulating component has a third opening for the stationary contact structure to pass through and a sixth opening for the lead-out probe to pass through. This ensures that an insulation withstand voltage level is formed around the stationary contact structure, thereby avoiding or mitigating the technical problem of the stationary contact structure being broken down by current under load. Thus, this embodiment ensures the normal operation of the relay, thereby improving the relay's safety performance.

By designing the size of the third opening to be smaller than the size of the second opening, an annular groove is formed at the assembly positions of the first boss, the second opening, and the third opening.

[0097] In order to make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. It is obvious that the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0098] As an electronic control device, a relay uses media (tools) such as electricity, light, magnetism, heat, etc. (i.e., input quantities) to transfer and control circuits or signals (i.e., output quantities). It has a control system (also known as an input circuit) and a controlled system (also known as an output circuit), and couples the two circuits through an internal mechanical or electronic device to achieve the linkage of the states of the two circuits. Relays are usually applied in automatic control circuits and play roles such as automatic regulation, safety protection, and circuit conversion in the circuit.

[0099] With the rapid development of the new energy industry, high-voltage DC relays are widely used in new energy vehicles and charging supporting equipment, photovoltaic / wind power generation systems, and engineering vehicles and other fields. In the vehicle-mounted market, the required mileage is getting higher and higher, so the space utilization of the battery is optimized as much as possible.

[0100] With the continuous expansion of the application fields of relays, the requirements for relays are also getting higher and higher. Especially for relays used in the new energy field, not only are relays required to meet the characteristics of high voltage and small size, but they are also required to be equipped with auxiliary contacts. Therefore, currently in the market, relays usually need to have an auxiliary contact function. In related technologies, the structural design of relays with auxiliary contacts cannot ensure the insulation withstand voltage level around the static contact structure, resulting in the static contact structure being relatively easy to be broken down by current when bearing a load.

[0101] To solve the above problems, the embodiments of the present application provide a new relay and an electrical device. The relay includes a main housing, a wiring board, a static contact structure, a lead-out probe, and an insulating member located between the main housing and the wiring board. The main housing is provided with a first opening and a fourth opening; the wiring board is provided with a second opening and a fifth opening; one end of the static contact structure is installed in the first opening, and the other end of the static contact structure passes through the second opening; one end of the lead-out probe is installed in the fourth opening, and the other end of the lead-out probe passes through the fifth opening; the insulating member is provided with a third opening for the static contact structure to pass through and a sixth opening for the lead-out probe to pass through. The embodiments of the present application can ensure the formation of an insulation withstand voltage level around the static contact structure, thereby avoiding or reducing the problem that the static contact structure is broken down by current when bearing a load.

[0102] The following detailed description, in conjunction with the accompanying drawings, describes the relay, battery pack structure, and electrical equipment provided in the embodiments of this application.

Figure 2 This is a schematic diagram of another structure of the relay provided in an embodiment of this application. Figure 3 This is a schematic diagram of the structure of the probe led out in the relay provided in the embodiment of this application. Figure 4 This is a schematic diagram of the stationary contact structure in the relay provided in the embodiments of this application. Figure 5 This is a schematic diagram of the structure of the insulating component in the relay provided in the embodiments of this application. Figure 6 This is a schematic diagram of the terminal block in the relay provided in the embodiment of this application. Figure 7 This is a schematic diagram of the assembly structure of the terminal block, insulating components, and main housing in the relay provided in the embodiments of this application.

[0104] Reference Figures 1 to 7 As shown in the figure, this application provides a relay 100, which may include a main housing 110, a terminal block 120, a stationary contact structure 140, and a lead-out probe 150. The main housing 110 may have a first opening 111 and a fourth opening 114, the terminal block 120 may have a second opening 121 and a fifth opening 122, one end of the stationary contact structure 140 is installed in the first opening 111, and the other end of the stationary contact structure 140 passes through the second opening 121, one end of the lead-out probe 150 is installed in the fourth opening 114, and the other end of the lead-out probe 150 passes through the fifth opening 122.

[0105] In this embodiment of the application, the relay 100 may further include an insulating member 130, which is located between the main housing 110 and the terminal block 120. The insulating member 130 has a third opening 131 for the static contact structure 140 to pass through and a sixth opening 132 for the lead-out probe 150 to pass through.

[0106] By providing an insulating member 130 between the main housing 110 and the terminal block 120, the insulating member 130 can isolate the main housing 110 and the terminal block 120. Furthermore, the insulating member 130 has a third opening 131 for the stationary contact structure 140 to pass through and a sixth opening 132 for the lead-out probe 150 to pass through. This ensures that an insulation withstand voltage level is formed around the stationary contact structure 140, thereby avoiding or mitigating the technical problem of the stationary contact structure 140 being broken down by current under load. Thus, this embodiment of the application can ensure the normal operation of the relay 100, thereby improving the safety performance of the relay 100.

[0107] It should be noted that, in this embodiment of the application, the main housing 110 can be a housing with a single-sided opening, and the material of the main housing 110 can be ceramic.

[0108] In this embodiment of the application, a first boss 112 may be provided at the outer edge of the first opening 111. The first boss 112 may protrude toward the terminal block 120. The second opening 121 and the third opening 131 may be fitted onto the first boss 112.

[0109] In this embodiment of the application, one end of the static contact structure 140 can be installed in the first opening 111 and cooperate with the first boss 112, and the other end of the static contact structure 140 can pass through the third opening 131 and the second opening 121.

[0110] In this embodiment, the size of the third opening 131 may be smaller than the size of the second opening 121, so that an annular groove 113 is formed at the assembly position of the first boss 112, the second opening 121 and the third opening 131.

[0111] Since the stationary contact structure 140 is installed within the first opening 111 and mates with the first boss 112, injecting insulating glue into the annular groove 113 ensures that an insulation withstand voltage level is formed around the stationary contact structure 140, thereby avoiding or mitigating the technical problem of the stationary contact structure 140 being broken down by current when subjected to load. Therefore, the embodiments of this application can ensure the normal operation of the relay 100, thereby improving the safety performance of the relay 100.

[0112] In some embodiments, an adhesive layer may be provided on at least one side of the insulating member 130 to facilitate the assembly and fixation of the insulating member 130 to the main housing 110. Exemplarily, the adhesive layer may be provided on both sides of the insulating member 130, or the adhesive layer may be provided on the side of the insulating member 130 facing the main housing 110. This application embodiment does not limit this.

[0113] In this embodiment, the static touch structure 140 may include a connected functional part 141 and a first connecting part 142 (see [link]). Figure 4 As shown), the first connecting part 142 is installed in the first opening 111 and cooperates with the first boss 112, and at least a portion of the functional part 141 is exposed relative to the side of the terminal block 120 that is away from the insulating member 130.

[0114] In one possible implementation, the static contact structure 140 can be a cylindrical structure with a flange at the top.

[0115] In this embodiment, a second boss 115 is provided at the outer edge of the fourth opening 114. The second boss 115 protrudes toward the terminal block 120, and the sixth opening 132 and the fifth opening 122 are sequentially mounted on the second boss 115.

[0116] In this embodiment of the application, one end of the probe 150 is installed in the fourth opening 114 and cooperates with the second protrusion 115, and the other end of the probe 150 passes through the sixth opening 132 and the fifth opening 122.

[0117] In the embodiments of this application, see Figure 3 As shown, the probe 150 may include a first probe portion 151, a second probe portion 152 and a second connecting portion 153 connected together, with the second connecting portion 153 located between the first probe portion 151 and the second probe portion 152.

[0118] The first probe portion 151 is located inside the main housing 110, the second connecting portion 153 cooperates with the second boss 115, the second probe portion 152 is electrically connected to the fifth opening 122 of the terminal block 120, and at least a portion of the second probe portion 152 is exposed relative to the side of the terminal block 120 away from the insulating member 130.

[0119] In this embodiment of the application, the size of the sixth opening 132 may be larger than the size of the fifth opening 122.

[0120] It should be noted that, in the embodiments of this application, the shapes of the first opening 111, the second opening 121, the third opening 131, the fourth opening 114, the fifth opening 122, and the sixth opening 132 can be circular, rectangular, or triangular, etc., and the embodiments of this application do not limit them in this way.

[0121] Taking the first opening 111, the second opening 121, the third opening 131, the fourth opening 114, the fifth opening 122, and the sixth opening 132 as examples, the first opening 111, the second opening 121, and the third opening 131 can be coaxially arranged, and the fourth opening 114, the fifth opening 122, and the sixth opening 132 can also be coaxially arranged.

[0123] Reference Figure 8 As shown in the embodiments of this application, the relay 100 may further include an arc suppression cover 160, wherein the arc suppression cover 160 may be disposed on the outer periphery of the main housing 110.

[0124] It should be noted that, in this embodiment, the arc-suppressing cover 160 can be a ring-shaped iron sheet used for magnetic conduction and arc extinguishing. The material used for the arc-suppressing cover 160 can be a soft magnetic material.

[0125] In some embodiments, one sidewall of the arc suppression cover 160 may have a notch. This facilitates the manufacturing and processing of the arc suppression cover 160.

[0126] In this embodiment of the application, the arc suppression cover 160 may include a first sidewall 1601 and a second sidewall 1602 opposite to each other, wherein magnetic elements 161 may be respectively provided between the first sidewall 1601 and the main housing 110 and between the second sidewall 1602 and the main housing 110.

[0132] In this embodiment, one end of the connecting component 170 can be connected to the support foot 163, and the other end of the connecting component 170 can be electrically connected to the terminal block 120.

[0139] In this embodiment of the application, the number of connecting pieces 171 can be two, and the bracket 172 can be provided with two grooves 1721, with the two connecting pieces 171 respectively disposed in the two grooves 1721.

[0140] In this embodiment, the protrusions 1723 in the two grooves 1721 are positioned differently, and the second through holes 1714 on the two connecting pieces 171 are positioned differently. This serves to prevent mistaken installation and ensures that the two connecting pieces 171 are installed backwards in the two grooves 1721 of the bracket 172.

[0141] like Figure 9 As shown in the embodiment of this application, the connecting piece 171 may include a first connecting segment 1711, a second connecting segment 1712, and a third connecting segment 1713 connected together. The third connecting segment 1713 may be located between the first connecting segment 1711 and the second connecting segment 1712. Moreover, the third connecting segment 1713 is bent between the first connecting segment 1711 and the second connecting segment 1712.

[0142] In this embodiment of the application, the second through hole 1714 may be disposed on the third connecting segment 1713.

[0143] In this embodiment of the application, a connector 1715 may be provided on the side of the first connecting segment 1711 facing away from the second connecting segment 1712, and a seventh opening 123 may be correspondingly opened on the terminal block 120, and the connector 1715 is installed in the seventh opening 123.

[0144] In this embodiment, an electrical connector 124 (see [reference]) may be provided on the side of the terminal block 120 facing the insulator 130. Figure 6 As shown, one end of the electrical connector 124 can be electrically connected to the connector 1715, and the other end of the electrical connector 124 can be electrically connected to the lead-out probe 150.

[0145] It is understood that the electrical connector 124 may be formed on the side of the terminal block 120 facing the insulator 130 by a printing process. For example, in some embodiments, the electrical connector 124 may be copper foil.

[0146] In addition, by forming the electrical connector 124 on the side of the terminal block 120 facing the insulator 130, the electrical connector 124 can be protected, and the electrical connector 124 is less likely to break when the relay 100 is subjected to an impact, making it more reliable.

A third protrusion 183 may be provided at the outer edge of the eighth opening 182. The third protrusion 183 can cooperate with the first opening 111, the second opening 121, and the third opening 131, that is, the third protrusion 183 cooperates with the annular groove 113. At this time, insulating glue can be poured into the annular groove 113, and the third protrusion 183 is installed by aligning it with the glue-filled annular groove 113 and curing together, which improves reliability.

[0150] In this embodiment, a plurality of reinforcing members 1811 may be provided on the outer edge of the mounting port 181. The reinforcing members 1811 extend toward the interior of the upper housing 180 to fix the arc suppression cover 160 inside the upper housing 180. The reinforcing members 1811 can help to press and fix the arc suppression cover 160.

[0151] In this embodiment of the application, a connector 184 may be provided on one of the outer side walls of the upper housing 180, and a second connecting segment 1712 extends out of the upper housing 180 and cooperates with the connector 184.

[0152] It should be noted that in some embodiments, such as Figure 9 As shown, the end of the second connecting segment 1712 can be narrowed to facilitate the matching of connector 184.

[0153] In this embodiment, the relay 100 has a very compact overall structure with fixed connections between all components. When subjected to external mechanical impact, the overall structure of the relay 100 is more stable, the signal transmission path is not easily broken, and faults such as circuit failure and inability to transmit signals can be avoided.
