[0046] The relay 100 and the electrical equipment according to an embodiment of the present utility model will be described below with reference to the drawings.
[0047] As Figure 1 、 Figure 2 and Figure 6 shown, the relay 100 according to an embodiment of the present utility model includes: a bracket 10, a relay body 20, a collection terminal 30, and an electrical connector 40.
[0048] Among them, the relay body 20 is connected to the bracket 10, and a plurality of static contact terminals 21 are provided on the relay body 20. The collection terminal 30 is connected to the bracket 10, and the collection terminal 30 is used to connect to a monitoring circuit, and the collection terminal 30 is at least two. The electrical connectors 40 are provided in one-to-one correspondence with the collection terminals 30, and each electrical connector 40 connects one collection terminal 30 and one static contact terminal 21.
[0049] It can be understood that the relay body 20 accesses the load circuit through the static contact terminals 21. When the current information (current intensity, voltage, etc.) in the load circuit changes, the current or information on the static contact terminals 21 will change accordingly.
[0050] Thus, the bracket 10 can provide support and fixation for the relay body 20. By integrating the collection terminals 30 on the bracket 10, the bracket 10 can also provide support for the collection terminals 30 to make the positions of the collection terminals 30 in the relay 100 more stable. Thereby improving the connection stability when the collection terminals 30 are used to connect to an external monitoring circuit.
[0051] In the relay 100 of the present application, the static contact terminals 21, the collection terminals 30, and the electrical connectors 40 are electrically connected through the electrical connectors 40, so that the current information on the electrical connectors 40 can be transmitted to the collection terminals 30, and then transmitted to the external monitoring circuit through the collection terminals 30. Thereby realizing the collection of the current information at the static contact terminals 21 by the monitoring circuit to monitor the working state of the relay 100 and improving the working safety and reliability of the relay 100.
[0052] In the present application, the number of the static contact terminals 21, the collection terminals 30, and the electrical connectors 40 is not limited. For example, in Figure 1In the example, the number of static contact terminals 21 and acquisition terminals 30 is two, and the number of electrical connectors 40 is also two. Each electrical connector 40 connects one acquisition terminal 30 and one static contact terminal 21.
[0053] Further, the acquisition terminal 30 is a rigid member, enabling the acquisition terminal 30 to have a certain load-bearing capacity. The relay 100 is fixed to the load current through the acquisition terminal 30.
[0054] It can be understood that the acquisition terminal 30 is relatively stable at the installation position of the relay 100 under the support of the bracket 10. Thus, the acquisition terminal 30 can be used for both electrically connecting to an external monitoring circuit and fixing the relay 100, thereby realizing the multi-purpose use of the acquisition terminal 30, simplifying the structure of the relay 100, and facilitating the reduction of the volume of the relay 100.
[0055] Preferably, the bracket 10 is provided with a limiting post 11. The acquisition terminal 30 is inserted into the limiting post 11. The limiting post 11 can limit the connection position of the acquisition terminal 30 on the bracket 10 while providing support for the acquisition terminal 30, improving the connection stability of the acquisition terminal 30 on the bracket 10 and the load-bearing capacity of the acquisition terminal 30 when used to fix the relay.
[0056] Preferably, the acquisition terminal 30 is connected to the circuit board by welding. At this time, the acquisition terminal 30 is electrically connected to the circuit board to realize the access of the acquisition terminal 30 to the monitoring circuit. At the same time, the relay 100 is fixed to the circuit board through the acquisition terminal 30, thereby simultaneously realizing the fixation of the relay 100 and the acquisition of the current information of the static contact terminal 21, facilitating the operation of fixing the relay 100 and accessing the monitoring current.
[0057] In some embodiments, as Figures 3 - 5 shown, the electrical connector 40 includes: a socket part 41 and an interconnecting part 42. The socket part 41 is sleeved on the static contact terminal 21, and the interconnecting part 42 is connected to the socket part 41 and the acquisition terminal 30 at both ends respectively.
[0058] Thus, the socket part 41 can improve the connection reliability between the electrical connector 40 and the static contact terminal 21, so as to improve the electrical connection reliability from the static contact terminal 21 to the acquisition terminal 30.
[0059] In this application, the shape of the interconnecting part 42 is not limited. For example, in Figure 1 , Figure 5 the example, the interconnecting part 42 is a long strip-shaped plate.
[0060] Preferably, the interconnecting part 42 is a copper bar.
[0061] Further, as Figure 3 , Figure 4As shown, the socket part 41 includes: a collar 411, and the collar 411 is sleeved on the static contact terminal 21.
[0062] It can be understood that the static contact terminal 21 is cylindrical. Thus, there are multiple contact positions between the static contact terminal 21 and the collar 411, which can improve the reliability of the contact between the socket part 41 and the static contact terminal 21.
[0063] Furthermore, a clamping groove 211 is provided on the outer peripheral surface of the static contact terminal 21. The socket part 41 further includes: a clamping protrusion 412 connected to the radial inner side of the collar 411, and the clamping protrusion 412 is fitted in the clamping groove 211 to define the installation position of the socket part 41 on the static contact terminal 21, so that the socket part 41 is fixed to the static contact terminal 21, and the electrical contact area between the socket part 41 and the static contact terminal 21 is increased.
[0064] Preferably, the clamping protrusion 412 is arranged as an elastic piece, which can facilitate the installation and disassembly of the socket part 41 on the static contact terminal 21.
[0065] Furthermore, as Figure 3 shown, a retaining rib 212 is provided on the outer peripheral surface of the static contact terminal 21, and the retaining rib 212 is located on one axial side of the clamping groove 211, and the collar 411 abuts against the retaining rib 212. Thus, the retaining rib 212 can define the installation position of the collar 411 on the static contact terminal 21, and can be used as a standard for installing the retaining rib 212 to the accurate position, that is, when the retaining rib 212 abuts against the clamping groove 211, the socket part 41 is installed to the accurate position on the static contact terminal 21.
[0066] Meanwhile, the clamping protrusion 412 extends away from the retaining rib 212 in the direction towards the axis of the static contact terminal 21, and the end of the clamping protrusion 412 is stuck in the clamping groove 211. Thus, the clamping protrusion 412 can limit the movement of the collar 411 in the direction away from the retaining rib 212, and provide a pressure towards the retaining rib 212 to the collar 411, so that the collar 411 can keep abutting against the retaining rib 212, and the position stability of the collar 411 is improved.
[0067] In some embodiments, as Figures 3 - 5 shown, the socket part 41 includes a first plugging part 413, and the interconnection part 42 is provided with a second plugging part 421 at the first end, and the first plugging part 413 and the second plugging part 421 are plugged and matched, which can facilitate the connection between the socket part 41 and the interconnection part 42.
[0068] In this application, the structural types of the first plugging part 413 and the second plugging part 421 are not limited. For example, in the Figure 4 、 Figure 5 example, the first plugging part 413 is arranged as a slot, and the second plugging part 421 is arranged as a plug head. Or, the first plugging part 413 is arranged as a plug head, and the second plugging part 421 is arranged as a slot.
[0069] Preferably, on the basis that the first plugging portion 413 and the second plugging portion 421 are plugged and matched, the first plugging portion 413 and the second plugging portion 421 are welded and connected. Thus, the plugging and matching can ensure the stability of the welding position between the first plugging portion 413 and the second plugging portion 421, thereby improving the firmness of the welding connection between the first plugging portion 413 and the second plugging portion 421.
[0070] In some embodiments, such as Figure 5 , Figure 6 and Figure 8 shown, the interconnecting member 42 is provided with a third plugging portion 422 at the second end, the collecting terminal 30 is provided with a fourth plugging portion 31, and the third plugging portion 422 and the fourth plugging portion 31 are plugged and matched, which can facilitate the connection between the interconnecting member 42 and the collecting terminal 30.
[0071] In this application, the structural types of the third plugging portion 422 and the fourth plugging portion 31 are not limited. For example, in the examples of Figure 4 , Figure 5 , the third plugging portion 422 is set as a plug head, and the fourth plugging portion 31 is set as a slot. For another example, the third plugging portion 422 is set as a slot, and the fourth plugging portion 31 is set as a plug head.
[0072] Preferably, on the basis that the third plugging portion 422 and the fourth plugging portion 31 are plugged and matched, the third plugging portion 422 and the fourth plugging portion 31 are welded and connected. Thus, the plugging and matching can ensure the stability of the welding position between the third plugging portion 422 and the fourth plugging portion 31, thereby improving the firmness of the welding connection between the third plugging portion 422 and the fourth plugging portion 31.
[0073] In some embodiments, the electrical connector 40 is a rigid member. It can be understood that there is a certain spatial distance between the collecting terminal 30 and the static contact terminal 21.
[0074] Therefore, using a rigid member for the electrical connector 40 enables it to span a certain distance while having a certain structural strength itself to maintain the structural stability of the electrical connector 40 itself, thereby improving the stability and reliability of the electrical connector 40 in connecting the static contact terminal 21 and the collecting terminal 30.
[0075] At the same time, the support structure for the electrical connector 40 can be reduced, thereby simplifying the structure of the relay 100 and being beneficial to reducing the volume of the relay 100.
[0076] In some embodiments, such as Figure 1 , Figure 2 and Figure 6As shown, the relay body 20 further includes a control coil 22 and a moving contact terminal 23 that are electrically connected to each other. The control coil 22 is used to control the movement of the moving contact terminal 23 relative to the static contact terminal 21 to control the contact and disconnection between the moving contact terminal 23 and the static contact terminal 21.
[0077] The relay 100 further includes two control terminals 50. The control terminals 50 are electrically connected to the control coil 22, and the two control terminals 50 are used to connect to a monitoring circuit.
[0078] Thus, the monitoring circuit can control the moving contact terminal 23 through the control terminal 50. When the monitoring circuit collects abnormal current information at the static contact terminal 21 through the acquisition terminal 30, it can control the control coil 22 through the control terminal 50 to control the movement of the moving contact terminal 23, so as to adjust the contact or disconnection between the moving contact terminal 23 and the static contact terminal 21. Thereby, while realizing the monitoring of the working condition of the relay 100, the current conduction and interruption of the relay 100 can be controlled according to the current information.
[0079] It should be noted that the control method of the control coil 22 for the moving contact terminal 23 is well known to those skilled in the art and will not be elaborated here.
[0080] Preferably, a limiting post 11 is provided on the bracket 10. The control terminal 50 is inserted into the limiting post 11. The limiting post 11 can limit the connection position of the control terminal 50 on the bracket 10 while providing support for the control terminal 50, improving the connection stability of the control terminal 50 on the bracket 10 and the bearing capacity of the control terminal 50 when fixing the relay.
[0081] Furthermore, as Figure 6 、 Figure 7 and Figure 9 shown, the control terminal 50 includes a winding post 51. Two lead-out ends of the control coil 22 are respectively wound around the winding posts 51 of the two control terminals 50.
[0082] It can be understood that the two lead-out ends of the control coil 22 are the two ends of the winding of the control coil 22. That is to say, the two ends of the winding of the control coil 22 are wound around the winding post 51 to form a reliable electrical contact between the winding and the winding post 51.
[0083] Thereby, it is convenient to electrically connect the control terminal 50 and the control coil 22, eliminating the need to provide an additional electrical connection structure between the control coil 22 and the control terminal 50, thus simplifying the structure of the relay 100 and being beneficial to reducing the volume of the relay 100.
[0084] In some embodiments, as Figure 1 、 Figure 2 、 Figure 6 and Figure 7As shown, the control terminal 50 is connected to the bracket 10, and the bracket 10 can also support the control terminal 50 to make the position of the control terminal 50 more stable within the relay 100, thereby improving the connection stability when the control terminal 50 is used to connect an external monitoring circuit.
[0085] Meanwhile, the control terminal 50 and the acquisition terminal 30 are arranged on the same side of the bracket 10, enabling the control terminal 50 and the acquisition terminal 30 to connect to the external monitoring circuit on the same side of the bracket 10, reducing the connection distance between the acquisition terminal 30 and the control terminal 50 and the external monitoring circuit.
[0086] Furthermore, both the acquisition terminal 30 and the control terminal 50 are rigid members, endowing the acquisition terminal 30 and the control terminal 50 with a certain load-bearing capacity, and the relay 100 is fixed to the load current through the acquisition terminal 30 and the control terminal 50.
[0087] It can be understood that, under the support of the bracket 10, the setting positions of the acquisition terminal 30 and the control terminal 50 in the relay 100 are relatively stable. Thus, the acquisition terminal 30 and the control terminal 50 can be simultaneously used for electrically connecting the external monitoring circuit and fixing the relay 100, thereby realizing the multi-purpose use of the acquisition terminal 30 and the control terminal 50, simplifying the structure of the relay 100, and being beneficial to reducing the volume of the relay 100.
[0088] Preferably, the acquisition terminal 30 and the control terminal 50 are welded to the circuit board. At this time, the acquisition terminal 30 and the control terminal 50 are electrically connected to the circuit board to realize the access of the acquisition terminal 30 and the control terminal 50 to the monitoring circuit. Meanwhile, the relay 100 is fixed to the circuit board through the acquisition terminal 30 and the control terminal 50, thereby simultaneously realizing the fixation of the relay 100, the acquisition of the current information of the static contact terminal 21, and the control of the moving contact terminal 23, facilitating the operation of fixing the relay 100 and accessing the monitoring current, eliminating the external structure for fixing the relay 100, and further reducing the volume of the relay 100.
[0089] In some embodiments, as Figure 10 、 Figure 11 shown, the relay 100 further includes: a housing 60, the housing 60 encloses to form an accommodation cavity, the bracket 10, the relay body 20, and the electrical connector 40 are located within the accommodation cavity, the housing 60 is provided with a first avoidance hole 61 and a second avoidance hole 62, the acquisition terminal 30 passes through the first avoidance hole 61 and part of it is located outside the housing 60, and the static contact terminal 21 is located in the second avoidance hole 62.
[0090] It can be understood that the static contact terminal 21 needs to be connected to a load circuit outside the relay 100, and the acquisition terminal 30 needs to be connected to an external monitoring circuit of the relay 100.
[0091] Thus, the housing 60 can protect the relay body 20, reducing or avoiding damage to the relay 100 caused by collision or short circuit due to contact with liquid.
[0092] Meanwhile, the static contact terminal 21 can be partially located outside the housing 60 through the second avoidance hole 62, so as to facilitate the connection of the static contact terminal 21 to an external load circuit. The acquisition terminal 30 can be partially located outside the housing 60 through the first avoidance hole 61, facilitating the connection of the acquisition terminal 30 to an external monitoring circuit.
[0093] Furthermore, when the relay 100 further includes a control terminal 50, the control terminal 50 is connected to an external monitoring circuit. The housing 60 further includes a third avoidance hole 63. The control terminal 50 passes through the third avoidance hole 63 and is partially located outside the housing 60, which can facilitate the connection of the control terminal 50 to an external control circuit.
[0094] Preferably, when the relay 100 is fixed through the control terminal 50 and the acquisition terminal 30, the control terminal 50 and the acquisition terminal 30 are partially located outside the housing 60, so as to facilitate the fixation of the relay 100 through the control terminal 50 and the acquisition terminal 30.
[0095] The electrical equipment according to the embodiment of the present invention includes the relay 100 of the above embodiment.
[0096] In the present application, the type of the electrical equipment is not limited. For example, the electrical device is a vehicle, and the relay is connected to the load circuit of the vehicle.
[0097] In the present application, the relay 100 of the above embodiment is adopted. The relay 100 electrically connects the static contact terminal 21 and the acquisition terminal 30 through the electrical connector 40, enabling the current information on the electrical connector 40 to be transmitted to the acquisition terminal 30, and then transmitted to an external monitoring circuit through the acquisition terminal 30. Thus, the monitoring circuit can collect the current information at the static contact terminal 21 to monitor the working state of the relay 100, improving the working safety and reliability of the relay 100 and the electrical equipment.
[0098] For those of ordinary skill in the art, the other constitutions and operations of the relay 100 and the electrical equipment according to the embodiments of the present invention are known and will not be described in detail here.
