Description

Technical Field

[0001] The present disclosure relates to the technical field of relays, and in particular, to a relay, a relay module and a vehicle. Background Art

[0002] A relay is an automatic switch that uses a small current to control the operation of a large current. It is usually used in automated control circuits and plays the role of automatic regulation, safety protection, and conversion circuits in the circuit.

[0003] In the related art, bolts are usually used to connect the copper bar and the static contact of the relay when the relay is connected in series with the control circuit. Specifically, one end of the copper bar is arranged on the upper end surface of the static contact of the relay, and the lower surface of the copper bar is in contact with the upper end surface of the static contact. The bolt passes through the through hole on the copper bar and is threadedly connected to the static contact, thereby pressing the copper bar against the static contact to achieve a conductive connection between the copper bar and the static contact. However, since the head of the bolt and the copper bar itself have a certain height, the height of the relay is increased and the required installation height is relatively high, which brings difficulties to the arrangement of components in the distribution space.

DETAILED DESCRIPTION

[0042] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0043] In the present disclosure, it should be understood that the directional words used, such as "upper" and "lower", etc., are defined by the drawing directions of the corresponding drawings, and are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, and a specific orientation structure and operation, and therefore cannot be understood as a limitation of the present disclosure. The terms "inside and outside" refer to the inside and outside of the corresponding structural contour. In addition, it should be noted that the terms used, such as "first", "second", etc., are used to distinguish one element from another, and do not have order and importance. In addition, in the description of the reference drawings, the same mark in different drawings represents the same element.

[0044] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0045] like Figures 1 to 5 As shown, according to the first aspect of the present disclosure, a relay 10 is provided, including a shell 11, a relay body 12 and an electrical connector 13, the relay body 12 is located in the shell 11, a static contact 121 is provided on the relay body 12, the static contact 121 is penetrated through the first end of the electrical connector 13, and the outer peripheral surface of the static contact 121 is conductively connected to the electrical connector 13, and the second end of the electrical connector 13 is exposed from the shell 11 and forms an external connection portion 131.

[0046] In the relay 10 provided in the present disclosure, since the static contact 121 is inserted into the first end of the electrical connector 13 (i.e., the first end of the electrical connector 13 is sleeved on the static contact 121), and the outer peripheral surface of the static contact 121 is conductively connected to the electrical connector 13, the electrical connector 13 can be prevented from occupying the height space of the relay and causing the overall height of the relay to increase, thereby facilitating the installation and arrangement of the relay.

[0047] Compared to the technical solution in the related art in which the copper bar is pressed against the upper end face of the static contact by bolts, in the relay 10 provided in the present invention, the static contact 121 is passed through the first end of the electrical connector 13, and the outer peripheral surface of the static contact 121 is connected to the electrical connector 13. There is no need to use bolts to connect the static contact 121 and the electrical connector 13. In this way, the space occupied by at least the head of the bolt and the electrical connector 13 can be reduced, thereby reducing the height dimension of the relay 10 and reducing the installation space required for the relay 10. This is conducive to the flexible arrangement of the relay 10 in the distribution space (such as a distribution box), so that the relay 10 is not easily interfered with by other equipment or components in the distribution space.

[0048] The present disclosure does not limit the depth of the static contact 121 inserted into the electrical connector 13. As an embodiment, the upper surface of the first end of the electrical connector 13 is flush with the upper end surface of the static contact 121. In other words, the static contact 121 can just completely pass through the electrical connector 13, and the upper surface of the first end of the electrical connector 13 does not protrude from the upper end surface of the static contact 121, so as to ensure that the first end of the electrical connector 13 does not occupy the height space of the relay and increase the overall height of the relay.

[0049] As another embodiment, the upper surface of the first end of the electrical connector 13 may also be lower than the upper end surface of the stationary contact 121. This design can also ensure that the upper surface of the first end of the electrical connector 13 does not protrude from the upper end surface of the stationary contact 121.

[0050] The present disclosure does not limit the specific position of the external connection portion 131 of the electrical connector 13. As an embodiment of the present disclosure, Figure 1 As shown, the height of the external connection portion 131 is lower than the upper end surface of the stationary contact 121. In this way, the external connection portion 131 lower than the upper end surface of the stationary contact will not increase the installation height required for the entire relay 10, which facilitates the layout of the relay 10. In other embodiments, the height of the external connection portion 131 can also be flush with the upper end surface of the stationary contact.

[0051] Optionally, the static contact 121 may be located at the top of the relay body 12 , and the external connection portion 131 may be located at the side of the relay body 12 , so that the external connection portion 131 is conveniently connected to a device that needs to be connected to the relay.

[0052] The electrical connector 13 may have any appropriate structure and shape. Figure 1 As shown, the electrical connector 13 may include a lead-out portion 132 and an intermediate connection portion 133, the static contact 121 is inserted through the lead-out portion 132, the intermediate connection portion 133 is connected between the lead-out portion 132 and the external connection portion 131, and the lead-out portion 132 and the external connection portion 131 are both arranged at an angle to the intermediate connection portion 133. Since the lead-out portion 132 and the external connection portion 131 are both arranged at an angle to the intermediate connection portion 133, the electrical connector 13 is bent as a whole, so that the external connection portion 131 and the lead-out portion 132 can be located at different positions, so that the electrical connector 13 can adapt to the position of other devices connected to the relay 10, and it is convenient for the relay 10 to be connected to other devices.

[0053] Alternatively, if Figures 1 to 4 As shown, the housing 11 includes an insulating base 111 and an insulating cover 112 , the relay body 12 is installed on the insulating base 111 , the static contact 121 is located on the side of the relay body 12 away from the base, and the insulating cover 112 is connected to the insulating base 111 and covers the static contact 121 and part of the electrical connector 13 .

[0054] In the relay 10 provided by the present disclosure, since the insulating cover 112 is connected to the insulating base 111 and covers the static contact 121 and part of the electrical connector 13, the insulating cover 112 can protect the static contact 121 and the electrical connector 13 on the one hand, and can also insulate the static contact 121 and the electrical connector 13 on the other hand. In this way, when the relay 10 is installed in the power distribution space, the static contact 121 and the part of the electrical connector 13 connected to the static contact 121 will not be in conductive contact with other components or conductive structures. Therefore, there is no need to consider the electrical gap between the relay 10 and other components, and other components, such as the control board 20, can be directly arranged on the side of the relay 10 close to the static contact 121. This can also further reduce the installation height required for the relay 10 as a whole, which is convenient for the arrangement of the relay 10.

[0055] Alternatively, if Figures 1 to 4 As shown, the insulating cover 112 may include a cover body 1121 and an insulating edge 1122 formed on the cover body 1121, and the insulating edge 1122 surrounds the side wall of the external connection portion 131. By providing the insulating edge 1122 on the side wall of the external connection portion 131, the overall insulation performance of the relay 10 can be improved, and the situation that the relay 10 and / or other components are short-circuited or even damaged due to the conductive contact between the side wall of the external connection portion 131 and other components or conductors is effectively avoided.

[0056] The present disclosure does not limit the specific structure and connection relationship of the insulating base 111 and the insulating cover 112. For example, the relay body 12 can be installed in the insulating base 111, and the insulating cover 112 can be detachably connected to the insulating base 111 and cover the relay body 12 in the insulating base 111.

[0057] As an exemplary embodiment provided by the present disclosure, Figures 1 to 3 As shown, the relay body 12 has an exposed portion exposed from the insulating base 111, the static contact 121 is located on the exposed portion, and the insulating cover 112 is an injection-molded part connected to the insulating base 111 as a whole through an injection molding process, and the injection-molded part covers the exposed portion, the static contact 121 and part of the electrical connector 13.

[0058] During manufacturing, the relay body 12 can be first installed on the insulating base 111, and the first end of the electrical connector 13 can be connected to the static contact 121, and then the insulating upper cover 112 can be formed by the injection molding process. In this way, on the one hand, the insulating cover 112 can be connected to the insulating base 111 as a whole through the injection molding process, and the connection between the insulating cover 112 and the insulating base 111 is reliable; on the other hand, since the insulating cover 112 is formed by the injection molding process, the lower surface of the insulating cover 112 can fit tightly to the static contact 121 and / or the electrical connector 13, and there is no gap between the lower surface of the insulating cover 112 and the static contact 121 and / or the electrical connector 13, which is conducive to further reducing the overall installation height required for the relay 10 and facilitating the arrangement of the relay 10.

[0059] In addition, after the relay is manufactured, the electrical connector 13 in the housing 11 and the outer peripheral surface of the static contact 121 are already in a connected state. When the relay 10 is connected in series with the circuit, it is only necessary to connect the external connection portion 131 of the electrical connector 13 exposed from the housing 11 to other devices in the circuit (such as a power supply, electrical equipment, etc.) to achieve the installation of the relay 10. Compared with the related technology, when installing the relay 10, it is necessary to respectively connect the two ends of the copper busbar to the relay 10 and the device to be connected to the relay, the relay 10 provided in the present disclosure integrates the electrical connector 13, and the user does not need to connect the static contact 121 and the electrical connector 13 during installation. This is conducive to simplifying the installation steps of the relay 10 and improving the installation efficiency of the relay 10.

[0060] In order to monitor the operating state of the relay 10, optionally, as Figures 1 to 3As shown, the relay 10 further includes a sampling pin 14, a first end of the sampling pin 14 is conductively connected to the electrical connector 13, a second end of the sampling pin 14 extends outward from the housing 11, and the second end of the sampling pin 14 is used to be inserted into the control board 20 and conductively connected to the sampling element on the control board 20. By electrically connecting the sampling pin 14 to the electrical connector 13 and the sampling element disposed on the control board 20, the sampling element can monitor the current and / or voltage of the electrical connector 13 in real time, thereby achieving real-time monitoring of the operating state of the relay 10.

[0061] In addition, since the sampling pin 14 can be directly inserted into the control board 20 and conductively connected to the sampling element on the control board 20, there is no need to set up components such as a wiring harness between the electrical connector 13 and the sampling unit to achieve a conductive connection between the electrical connector 13 and the sampling unit, which can facilitate the connection and installation of the relay and the control board 20.

[0062] The present disclosure does not limit the specific position of the sampling pin 14 in the relay 10, as long as the first end of the sampling pin 14 can be conductively connected to the electrical connector 13, and the other end of the sampling pin 14 can be inserted into the control board 20. As an embodiment of the present disclosure, Figures 1 to 3 As shown, the sampling pin 14 includes a pin body 141 and a connecting plate 142, wherein the connecting plate 142 covers the upper surface of the first end of the electrical connector 13 and is conductively connected to the electrical connector 13, and the pin body 141 extends from the connecting plate 142 in a direction away from the electrical connector 13 and is used to insert into the control board 20.

[0063] Since the connecting plate 142 covers the upper surface of the first end of the electrical connector 13 and is conductively connected to the electrical connector 13, in other words, the sampling pin 14 is also integrated on the electrical connector 13. Compared with the installation method in the related art that requires punching holes on the electrical connector to fix the sampling line nose, the above technical solution provided by the present disclosure effectively avoids the situation that the installation of the sampling line nose on the relay is more complicated due to the need to punch holes on the electrical connector to fix the sampling line nose, and simplifies the assembly process and installation steps of the relay 10.

[0064] In addition, since the pin body 141 extends from the connecting plate 142 in a direction away from the electrical connector 13 and is inserted into the control board 20, the connection points of the static contact 121, the electrical connector 13 and the sampling pin 14 of the relay 10 are all arranged in the housing 11. In this way, the control board 20 used to control and sample the relay 10 can be directly arranged above the housing 11 of the relay 10 (i.e., on the side close to the static contact 121) without considering the electrical gap, which is also beneficial to improving the integration and space utilization of the relay 10 and the control board 20, thereby improving the utilization of the distribution space.

[0065] like Figure 5As shown, the relay body 12 may include a stationary contact 121, a moving contact (not shown in the figure), a permanent magnet 123, a magnet support 124, a ceramic component 125, a coil 126, a coil support 127 for mounting the coil 126, and a support 128 and a support plate 129 clamped on the coil support 127. Among them, the ceramic component 125 is sleeved on the stationary contact 121, the permanent magnet 123 is mounted on both sides of the ceramic component 125 through the magnet support 124, and the moving contact is movably mounted on the support plate 129, and can move in a direction close to the stationary contact 121 or away from the stationary contact 121 under the action of the coil 126. In this way, by controlling the direction of the magnetic field generated by the coil 126 and controlling the movement of the moving contact, the moving contact can be conductively connected to the two stationary contacts 121 at the same time, or the moving contact can be separated from the two stationary contacts 121, thereby realizing the on and off of the relay 10.

[0066] In order to realize the control of on and off of the relay 10, optionally, as Figures 1 to 3 As shown, the relay 10 further includes a control pin 15, and the relay body 12 further includes a coil 126. The first end of the control pin 15 is conductively connected to the coil 126, and the second end of the control pin 15 extends outward from the housing 11. The second end of the control pin 15 is used to be inserted into the control board 20 and conductively connected to the control element on the control board 20. By connecting the first ends of the two control pins 15 to the positive and negative electrodes of the coil 126 respectively, and inserting the second ends of the two control pins 15 into the control board 20 and conductively connected to the control element on the control board 20, the control board 20 can control the coil 126, thereby realizing the control of the relay 10 on and off.

[0067] In addition, since one end of the control pin 15 can be connected to the coil 126, and the other end of the control pin 15 can be directly inserted into the control board 20 and conductively connected to the control element on the control board 20, there is no need to set up a wiring harness and a wiring harness connector between the coil 126 of the relay 10 and the control board 20 to achieve the connection between the coil 126 and the control board 20, thereby realizing the control of the relay 10 by the control board 20, which is also conducive to simplifying the connection between the relay 10 and the control board 20.

[0068] The present disclosure does not limit the specific connection relationship between the control pin 15 and the coil 126 of the relay body 12. As an embodiment of the present disclosure, Figures 1 to 3As shown, the relay body 12 may further include a coil support 127 for mounting the coil 126, and the control pin 15 is integrally formed with the coil support 127. Since the control pin 15 is integrally formed on the coil support 127 for mounting the coil 126 and is conductively connected to the coil 126, the control pin 15 is reliably fixed on the coil support 127, which effectively avoids the control pin 15 from shaking during use, causing the control pin 15 to be disconnected from the coil 126, so that the control board 20 cannot control the power on and off of the relay 10.

[0069] It should be noted that the present disclosure does not limit the specific connection relationship between the static contact 121 and the electrical connector 13. As long as the static contact 121 is inserted into the first end of the electrical connector 13 and the outer peripheral surface of the static contact 121 is conductively connected to the electrical connector 13, as an embodiment of the present disclosure, the above-mentioned electrical connector 13 can be integrally formed with the static contact 121.

[0070] As another embodiment of the present disclosure, the electrical connector 13 and the static contact 121 may also be connected by welding.

[0071] Here, it should be noted that the present disclosure does not limit the specific connection sequence between the stationary contact 121, the electrical connector 13, and the ceramic component 125. For example, the stationary contact 121 may be connected to the electrical connector 13 first, and then the combination of the stationary contact 121 and the electrical connector 13 may be brazed with the ceramic component 125 to achieve sealing. Similarly, the stationary contact 121 may be brazed with the ceramic component 125 first, and then the stationary contact 121 may be connected to the ceramic component 125.

[0072] It is understandable that, for the embodiment in which the relay body 12 includes the sampling pin 14 and the sampling pin 14 is connected to the electrical connector 13, the present disclosure does not limit the connection sequence between the static contact 121, the electrical connector 13 and the sampling pin 14. For example, the sampling pin 14 may be first connected to the electrical connector 13, and then the combination of the sampling pin 14 and the electrical connector 13 may be connected to the static contact 121. In addition, the electrical connector 13 may be first connected to the static contact 121, and then the sampling pin 14 may be connected to the combination of the electrical connector 13 and the static contact 121.

[0073] In order to improve the safety of the circuit where the relay 10 is located, optionally, as Figure 3 As shown, the relay 10 may further include a fuse element 16, which is mounted on the housing 11. The fuse element 16 can protect the circuit where the relay 10 is located. When the circuit is overloaded, the fuse element 16 can disconnect the entire circuit in time, thereby protecting the relay 10 and other components arranged in the circuit.

[0074] The safety element 16 can be exposed from the housing 11 for easy maintenance and replacement. For example, in the embodiment where the housing 11 includes an insulating base 111 and an insulating cover 112, as an embodiment, the safety element 16 can be disposed on the insulating base 111 and exposed from the insulating cover 112 for easy maintenance and replacement.

[0075] Here, it should be noted that the number of relay bodies 12 in the relay 10 of the present disclosure is not limited. The relay 10 may have only one relay body 12 or multiple relay bodies 12. As an embodiment of the present disclosure, Figures 1 to 4 As shown, there are multiple relay bodies 12, each relay body 12 is provided with an electrical connector 13, and a magnet 123 is provided between each adjacent two relay bodies 12. Multiple relay bodies 12 can be connected in series and / or in parallel to meet the use requirements of the equipment using the relay 10.

[0076] At the same time, since a magnet 123 is provided between each two adjacent relay bodies 12 , the magnet 123 can demagnetize the relay body 12 and reduce the electromagnetic interference between the two adjacent relay bodies 12 , thereby meeting the normal use requirements of the relay 10 .

[0077] Here, it should be noted that the present disclosure does not limit the series-parallel relationship between the multiple relay bodies 12 in the relay 10. The multiple relay bodies 12 in the relay 10 can be connected in series or in parallel with each other, and the multiple relay bodies 12 in the relay 10 can also be partially connected in series and partially connected in parallel. Figures 1 to 4 In the relay 10 shown, two relay bodies 12 are connected in series with each other and in parallel with another relay body 12 .

[0078] The present disclosure does not limit the specific connection relationship between the electrical connector 13 and the relay body 12. One electrical connector 13 can be connected to a static contact 121 on a relay body 12, and one electrical connector 13 can also be connected to static contacts 121 on multiple relay bodies 12 at the same time. Figure 1 As shown, the two stationary contacts 121 on the two relay bodies 12 are connected via an electrical connector 13 , which helps to reduce the number of electrical connectors 13 in the entire relay 10 , thereby simplifying the structure of the relay 10 .

[0079] In addition, for the embodiment in which the relay 10 includes a plurality of relay bodies 12, the present disclosure does not limit the relationship between the plurality of relay bodies 12 and the housing 11. As an embodiment of the present disclosure, optionally, as Figures 1 to 4As shown, the multiple relay bodies 12 are all disposed in the same housing 11. As another embodiment, the multiple relay bodies 12 may also be provided with corresponding housings 11, and the multiple housings 11 are connected to each other.

[0080] In addition, for the embodiment in which the housing 11 includes an insulating base 111 and an insulating cover 112, multiple relay bodies 12 can be installed on the same insulating base 111, and multiple insulating covers 112 corresponding to the multiple relay bodies 12 can be formed by an injection molding process; or an insulating cover 112 corresponding to the multiple relay bodies 12 can be formed by an injection molding process, and the present disclosure is not limited to this.

[0081] A second aspect of the present disclosure provides a relay module 100 , comprising the relay 10 as described above.

[0082] The relay module 100 includes all the beneficial effects of the above-mentioned relay 10, which will not be described in detail here.

[0083] In order to monitor the operating state of the relay 10, optionally, Figure 3 and Figure 4 As shown, the above-mentioned relay module 100 may also include a control board 20, which is mounted on the housing 11. A sampling element is arranged on the control board 20. The control board 20 includes a board body 21, a first circuit arranged in the board body 21 and a first buckle 22 arranged on the board body 21. The first buckle 22 is electrically connected to the sampling element through the first circuit. The relay 10 also includes a sampling pin 14. The first end of the sampling pin 14 is conductively connected to the electrical connector 13. The second end of the sampling pin 14 extends outward from the housing 11 and is inserted into the first buckle 22. The second end of the sampling pin 14 is in electrically conductive contact with the first buckle 22.

[0084] Since the control board 20 is mounted on the housing 11, the first end of the sampling pin 14 is electrically connected to the electrical connector 13, and the second end of the sampling pin 14 is electrically connected to the sampling element through the first buckle 22 and the first circuit provided on the board 21. On the one hand, the electrical connector 13 and the sampling unit can be electrically connected without the need to provide a wiring harness and wiring harness connector and other components between them, and the structure of the relay module 100 is relatively simple. On the other hand, the gap between the control board 20 and the housing 11 of the relay 10 is small, the relay module 100 has a high degree of integration, and occupies a small space.

[0085] In addition, since a first buckle 22 is provided on the board body 21 of the control board 20, and the second end of the sampling pin 14 extends out of the shell 11 and is inserted into the first buckle 22, the connection between the sampling pin 14 and the control board 20 is reliable, which effectively avoids the situation in which the sampling pin 14 falls off the control board 20 during use and the control board 20 is unable to monitor the operating status of the relay 10.

[0086] In order to realize the control of the relay 10 being energized and disconnected, optionally, as Figure 3 and Figure 4 As shown, the relay module 100 also includes a control board 20, which is mounted on the housing 11. The control board 20 is provided with a control element. The control board 20 includes a board body 21, a second circuit arranged in the board body 21 and a second buckle 23 arranged on the board body 21. The second buckle 23 is electrically connected to the control element through the second circuit. The relay 10 also includes a control pin 15. The relay body 12 also includes a coil 126. The first end of the control pin 15 is conductively connected to the coil 126. The second end of the control pin 15 extends outward from the housing 11 and is inserted into the second buckle 23. The second end of the control pin 15 is in conductive contact with the second buckle 23.

[0087] Since the control board 20 is mounted on the housing 11, the first end of the control pin 15 is electrically connected to the coil 126, and the second end of the control pin 15 is electrically connected to the control element through the second buckle 23 and the second circuit provided on the board 21, on the one hand, the conductive connection between the coil 126 and the control unit can be achieved without the need to provide a wiring harness and wiring harness connector and other components between the coil 126 and the control unit, and the structure of the relay module 100 is relatively simple. On the other hand, the gap between the control board 20 and the housing 11 of the relay 10 is small, the relay module 100 has a high degree of integration, and occupies a small space.

[0088] In addition, since a second buckle 23 is provided on the board body 21 of the control board 20, and the second end of the control pin 15 extends out of the shell 11 and is inserted into the second buckle 23, the connection between the sampling pin 14 and the control board 20 is reliable, which effectively avoids the control pin 15 falling off from the control board 20 during use, and the control board 20 is unable to control the relay 10.

[0089] A third aspect of the present disclosure provides a vehicle, comprising the relay 10 as described above or the relay module 100 as described above.

[0090] The vehicle has all the beneficial effects of the above-mentioned relay 10 or relay module 100, which will not be repeated here.

[0091] It should be noted that the present disclosure does not limit the type of vehicle, which can be any vehicle suitable for using the above-mentioned relay 10 or relay assembly 100. For example, the vehicle can be a car, a truck, a van, etc., and can be a pure electric vehicle, a hybrid electric vehicle (extended range vehicle), etc., which is not limited by the present disclosure.

[0092] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0093] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0094] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
