TECHNICAL FIELD

[0001] The present application relates to the technical field of relays, and particularly relates to a relay. BACKGROUND

[0002] A conventional relay is generally provided with a main contact assembly, an auxiliary contact assembly, a coil assembly and an armature assembly on a base. The coil assembly can drive the armature assembly to move relative to the base by electromagnetic force, so as to make a main moving spring part of the main contact assembly contact or separate from a main static spring part, and make an auxiliary moving spring part of the auxiliary contact assembly contact or separate from an auxiliary static spring part. The contact or separation of the main moving spring part and the main static spring part can control the on-off of an external circuit, and the contact or separation of the auxiliary moving spring part and the auxiliary static spring part can control the on-off of a monitoring circuit of the main contact assembly. However, in the conventional relay, the setting of the auxiliary contact assembly occupies a large space, which easily leads to the increase of the size of the relay. CONTENT OF THE UTILITY MODEL

[0034] Please see Figures 1-4 , Figure 1 and Figure 2 These are schematic diagrams showing the structure of the relay 10 at different angles in some embodiments. Figure 3 for Figure 2 The diagram shown is a structural schematic of the relay 10 without the base 11. Figure 4 for Figure 3The diagram shows an enlarged view of the circular frame area of ​​the relay 10. The relay 10 provided in this application can be connected to any applicable external circuit to control the on / off state of the external circuit. In some embodiments, the relay 10 includes a base 11 and an electromagnetic system, a push card 14, and a main contact assembly 15 disposed on the base 11. The electromagnetic system includes a coil assembly 12, a yoke, and an armature assembly 13. The yoke passes through the coil assembly 12 and is used to conduct the magnetic field generated by the coil assembly 12. The main contact assembly 15 includes an active spring portion 151 and a main stationary spring portion 152 passing through the base 11. The active spring portion 151 and the main stationary spring portion 152 pass through the base 11 and extend out of the end of the relay 10 to be electrically connected to an external circuit. The active spring portion 151 is connected to the push card 14. The armature assembly 13 may include a plastic housing and a permanent magnet and an armature disposed within the plastic housing. The two armatures are disposed on opposite sides of the permanent magnet. When the coil is energized or the direction of the current in the coil changes, the armature assembly 13 can be driven to rotate relative to the base 11 by means of electromagnetic force. This causes the pusher 14 to drive the active spring part 151 to move closer to or further away from the main stationary spring part 152, so that the active spring part 151 and the main stationary spring part 152 can contact or separate, thereby realizing the on / off control of the external circuit.

[0035] In some embodiments, the relay 10 further includes an auxiliary contact assembly 16, which includes an auxiliary moving spring portion 161 and an auxiliary stationary spring portion 162 passing through the base 11. The ends of the auxiliary moving spring portion 161 and the auxiliary stationary spring portion 162 extending out of the base 11 can be electrically connected to the monitoring circuit of the main contact assembly 15. The movement of the armature assembly 13 relative to the base 11 can also cause the auxiliary moving spring portion 161 to move towards or away from the auxiliary stationary spring portion 162, so that the auxiliary moving spring portion 161 contacts or separates from the auxiliary stationary spring portion 162, thereby realizing the on / off switching of the monitoring circuit of the main contact assembly 15.

[0036] Furthermore, in some embodiments, the auxiliary spring portion 161 includes a fixing portion 1611 and a conducting portion 1612. The fixing portion 1611 is disposed on the base 11, and the armature assembly 13 can move relative to the base 11 such that at least a portion of the conducting portion 1612 moves relative to the fixing portion 1611 in a direction closer to or further away from the auxiliary stationary spring portion 162 along a first direction 171, which is parallel to the thickness direction of the base 11. That is, at least a portion of the conducting portion 1612 and the auxiliary stationary spring portion 162 can extend along a second direction 172 perpendicular to the first direction 171, and the conducting portion 1612 and the auxiliary stationary spring portion 162 can move closer to or further away from each other in the thickness direction of the base 11, achieving engagement in the thickness direction. It should be noted that, in this application, the naming of the base 11 does not imply a limitation on the structure and placement of the base 11. In the relay 10, the placement of the base 11 is not limited, and the base 11 includes, but is not limited to, a base structure, an upper shell structure, or an outer shell structure.

[0037] The relay 10 described above is designed such that the armature assembly 13 drives the conducting part 1612 to move relative to the fixed part 1611 in the first direction 171 toward or away from the auxiliary stationary spring part 162, so as to achieve contact or separation between the conducting part 1612 and the auxiliary stationary spring part 162. This allows the parts of the conducting part 1612 and the auxiliary stationary spring that are in contact with the conducting part 1612 to extend in the direction perpendicular to the thickness of the fixed part 1611 rather than in the direction parallel to the thickness of the fixed part 1611. This helps to compress the space occupied by the auxiliary contact assembly 16 in the thickness direction of the base 11, thereby helping to reduce the thickness of the relay 10.

[0038] Furthermore, in some embodiments, the push card 14 extends along a third direction 173 perpendicular to the first direction 171, an auxiliary contact assembly 16 is disposed at one end of the push card 14 in the first direction 171, and an auxiliary moving spring portion 161 is connected to one end of the push card 14 in the first direction 171. The auxiliary moving spring portion 161 and the auxiliary stationary spring portion 162 pass through the base 11 at positions opposite to the push card 14, and in the first direction 171, at least a portion of the conductive portion 1612 and at least a portion of the auxiliary stationary spring portion 162 located on the side of the base 11 facing the push card 14 are located between the base 11 and the push card 14. That is, the projection of the push card 14 on the base 11 covers at least a portion of the projections of the conductive portion 1612 and the auxiliary stationary spring portion 162 on the base 11, and in a plane perpendicular to the first direction 171, the push card 14 coincides with at least a portion of the conductive portion 1612 and the auxiliary stationary spring portion 162. Therefore, it can be understood that by designing the auxiliary contact assembly 16 as a snap-fit ​​design along the first direction 171, the relay 10 effectively compresses the size of the auxiliary contact assembly 16 in the thickness direction of the base 11. This allows the snap-fit ​​portion of the auxiliary contact assembly 16 to be positioned between the push card 14 and the base 11 in the first direction 171, effectively reducing the space occupied by the auxiliary contact assembly 16 and the push card 14 as a whole in the length direction (third direction 173) and width direction (second direction 172) of the base 11, which is beneficial to further compressing the size of the relay 10.

[0039] In some embodiments, the push card 14 has a groove 141 recessed towards the base 11 in the middle, which helps to increase the receiving space between the push card 14 and the base 11, thereby facilitating the placement of the auxiliary contact assembly 16 between the push card 14 and the base 11, fully compressing the space occupied by the auxiliary contact assembly 16 and the push card 14, and also helping to ensure that the end of the push card 14 has sufficient size to meet the assembly requirements of the auxiliary moving spring portion 161.

[0040] In some embodiments, the relay 10 may have two sets of main contact assemblies 15, which are respectively located at both ends of the push card 14 and on opposite sides of the auxiliary contact assembly 16 in the third direction 173. The active spring portions 151 of the two sets of main contact assemblies 15 are respectively connected to both ends of the push card 14 in the third direction 173. The two sets of main contact assemblies 15 pass through the base 11 and exit the relay 10 to communicate with different external circuits. When the armature assembly 13 drives the push card 14 to move along the third direction 173, it can simultaneously drive the active spring portions 151 in the two sets of main contact assemblies 15 to move towards or away from the main stationary spring portions 152, thereby simultaneously controlling the contact and separation of the active spring portions 151 and the main stationary spring portions 152 in the two sets of main contact assemblies 15, enriching the functions of the relay 10. Meanwhile, the layout of the two sets of main contact components 15, push card 14 and auxiliary contact components 16 is reasonably designed, so that the main contact components 15 and auxiliary contact components 16 are less likely to interfere with each other, which is also conducive to reducing the space occupied by the relay 10 and improving the space utilization efficiency of the relay 10.

[0041] Combination Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the armature assembly 13 includes a main body 131, a toggle part 132, a pusher part 133, and a magnet disposed within the main body 131. The main body 131 is rotatable relative to the base 11 about an axis parallel to the first direction 171. The toggle part 132 and the pusher part 133 are connected to the same side of the main body 131 and are spaced apart. The magnet includes, but is not limited to, a permanent magnet. The magnetic field generated by the coil assembly 12 can generate a mutual magnetic field force with the permanent magnet, causing the main body 131 to rotate relative to the base 11 about an axis parallel to the first direction 171, thereby causing the toggle part 132 and the pusher part 133 to move relative to the base 11. The pushing part 133 is rotatably connected to the pushing card 14 about an axis parallel to the first direction 171. When the pushing part 133 rotates with the main body 131 relative to the base 11, it can drive the pushing card 14 to move along the third direction 173, thereby controlling the contact or disconnection of the active spring part 151 and the main stationary spring part 152 in the main contact assembly 15. The actuating part 132 is provided on one side of the auxiliary moving spring in the third direction 173. When the actuating part 132 rotates with the main body 131 relative to the base 11, it can drive the auxiliary moving spring part 161 to move towards the auxiliary stationary spring part 162 until the auxiliary moving spring part 161 contacts the auxiliary stationary spring part 162. When the actuating part 132 leaves the auxiliary moving spring part 161, the auxiliary moving spring part 161 can leave the auxiliary stationary spring part 162 under its own elastic restoring force.

[0042] By providing a pusher 133 and a toggle 132 spaced apart on the armature assembly 13 to control the contact or disconnection of the active spring portion 151 and the main stationary spring portion 152, as well as the contact or disconnection of the auxiliary active spring portion 161 and the auxiliary stationary spring portion 162, the main contact assembly 15 and the auxiliary contact assembly 16 can be controlled by one armature assembly 13. This helps to reduce the number of parts in the relay 10 and improve the space utilization efficiency of the relay 10.

[0043] In some embodiments, the main body 131, the actuating part 132, and the pushing part 133 can be an integral structure, such as being integrally injection molded from plastic material. Of course, the actuating part 132 and the pushing part 133 can also be disposed on the main body 131 by any applicable connection method such as threaded connection or bonding. In some embodiments, the actuating part 132 and the pushing part 133 are arranged sequentially in the direction from the base 11 to the push card 14 along the first direction 171. This can adapt to the spatial layout between the auxiliary contact assembly 16 and the push card 14, simplifying the component composition and improving operational reliability while driving the auxiliary spring part 161 and the push card 14 to move respectively.

[0044] Combination Figure 2 , Figure 5 and Figure 6 As shown, in some embodiments, the auxiliary stationary spring portion 162 is provided with an auxiliary stationary contact 1622, and the auxiliary moving spring portion 161 is provided with two conductive portions 1612. Both conductive portions 1612 are connected to the fixed portion 1611 and are spaced apart in the second direction 172. The auxiliary moving spring portion 161 also includes two auxiliary moving contacts 1614 respectively provided on the two conductive portions 1612. The arrangement of the two conductive portions 1612 connected to one fixed portion 1611 allows the two auxiliary moving contacts 1614 to be connected in parallel through the fixed portion 1611, simplifying the wiring of the auxiliary moving spring portion 161. In other embodiments, the two conductive portions 1612 may also be connected to the two fixed portions 1611 respectively, and the parallel connection of the two auxiliary moving contacts 1614 can be realized through an external circuit.

[0045] Driven by the actuating part 132, the two conductive parts 1612 can move towards the auxiliary stationary spring part 162, or move away from the auxiliary stationary spring part 162 by means of their own elastic restoring force, so that the two auxiliary moving contacts 1614 can contact or separate from the auxiliary stationary contacts 1622. The auxiliary stationary contacts 1622 can adopt an elongated strip structure extending along the second direction 172. The two auxiliary moving contacts 1614 can respectively contact the auxiliary stationary contacts 1622 at two spaced positions in the second direction. The use of elongated auxiliary stationary contacts 1622 is beneficial to increasing the contact area and maintaining effective contact even when the auxiliary moving spring part 161 is slightly misaligned, thereby improving the reliability of the electrical connection. Of course, in some other embodiments, the auxiliary stationary spring part 162 can also be provided with two auxiliary stationary contacts 1622 corresponding one-to-one with the auxiliary moving contacts 1614, and each auxiliary stationary contact 1622 is used to contact one of the auxiliary moving contacts 1614. The auxiliary contact assembly 16 adopts a multi-point contact method to improve the reliability of electrical contact. By simultaneously driving the two conducting parts 1612 relative to the auxiliary stationary spring part 162 through the toggle part 132, the component composition of the relay 10 can be simplified. With the design of the auxiliary contact assembly 16 engaging in the first direction 171, the space occupied by the auxiliary contact assembly 16 in the thickness direction of the base 11 can be effectively reduced.

[0046] It should be noted that the number of auxiliary moving contacts 1614 is not limited to those described above; there may be one or more. Correspondingly, the conductive part 1612 can also accommodate one or more auxiliary moving contacts 1614. Providing multiple auxiliary moving contacts 1614 can improve the contact reliability between the auxiliary moving spring part 161 and the auxiliary stationary spring part 162, preventing contact failure due to the failure of individual contacts. Furthermore, the parallel connection of multiple auxiliary moving contacts 1614 helps reduce the total contact resistance, suppresses temperature rise, and improves performance reliability.

[0047] In some embodiments, at least a portion of the conductive portion 1612 is bent in a third direction 173. For example, the conductive portion 1612 includes a contact portion 1613, a first deformation portion 1615, and a second deformation portion 1616 connected sequentially in the direction from the auxiliary stationary spring portion 162 to the fixed portion 1611 along the third direction 173. An auxiliary moving contact 1614 is provided on the contact portion 1613. The first deformation portion 1615 and the second deformation portion 1616 are inclined to each other. That is, the conductive portion 1612 is bent at the first deformation portion 1615 and the second deformation portion 1616. This design increases the deformation of the conductive part 1612, allowing it to deform when in close contact with the auxiliary stationary spring part 162. This ensures smooth recovery after separation from the auxiliary stationary spring part 162, preventing excessive contact force that could cause the conductive part 1612 to deform and fail to recover, thus affecting the contact accuracy of the auxiliary contact assembly 16. Furthermore, the increased flexibility of the conductive part 1612 reduces the reaction force of the auxiliary moving spring part 161 on the actuating part 132 when the actuating part 132 pushes it. This reduces the resistance force of the auxiliary moving spring part 161 on the armature assembly 13 during main contact closure, improving operational stability.

[0048] In some embodiments, rotation of the main body 131 about an axis parallel to the first direction 171 causes the actuating portion 132 to move along a third direction 173, thereby pushing the conducting portion 1612 to move relative to the fixed portion 1611. For example, the actuating portion 132 is located on the side of the first deformable portion 1615 facing away from the auxiliary stationary spring portion 162, and the first deformable portion 1615 and the second deformable portion 1616 are inclined to form an opening facing the actuating portion 132. That is, the actuating portion 132 moves the conducting portion 1612 toward the auxiliary stationary spring portion 162 by abutting against the inclined surface formed by the first deformable portion 1615 facing away from the auxiliary stationary spring portion 162. This configuration effectively enables the movement of the conductive part 1612 relative to the auxiliary stationary spring part 162 in the first direction 171. Furthermore, by adjusting the tilt angles of the first deformable part 1615 and the second deformable part 1616 relative to the base 11, the contact position between the actuating part 132 and the conductive part 1612, as well as the travel distance of the conductive part 1612 relative to the auxiliary stationary spring part 162, can be controlled without adjusting the position of the actuating part 132 on the main body 131. This simplifies the adjustment process for the mating position of the actuating part 132 and the conductive part 1612, reducing the manufacturing difficulty and cost of the relay 10. Moreover, since the auxiliary contact assembly 16 is mounted in the middle of the base 11, bending the conductive part 1612 allows the grounding position of the actuating part 132 and the first deformable part 1615 to be relatively far from the center position of the armature assembly 13, i.e., far from the position where the magnetic attraction of the armature assembly 13 is weakest, ensuring operational stability.

[0049] Combination Figure 7 and Figure 8 As shown, in some embodiments, the base 11 is provided with a positioning protrusion 111 facing the push card 14. The auxiliary moving spring portion 161 also includes a positioning portion 1617 connected to the fixing portion 1611. The fixing portion 1611 passes through the base 11, and the positioning portion 1617 is sleeved on the positioning protrusion 111. The surface of the positioning portion 1617 facing the base 11 can at least partially conform to the base 11. The fixing portion 1611, the conducting portion 1612, and the positioning portion 1617 can be an integral structure. Providing the fixing portion 1611 can improve the assembly accuracy and fixing reliability of the auxiliary moving spring portion 161 on the base 11.

[0050] Please see again. Figure 2 and Figure 4 As shown, in some embodiments, the auxiliary stationary spring portion 162 includes a mounting portion 1621, and an auxiliary stationary contact 1622 is disposed on the mounting portion 1621. Both the mounting portion 1621 and the auxiliary stationary contact 1622 are rigid structures. The mounting portion 1621 passes through the base 11, and the portion of the mounting portion 1621 located on the side of the base 11 facing the push card 14 is attached to the surface of the base 11. The auxiliary stationary contact 1622 passes through the mounting portion 1621 and is inserted into the base 11. The cooperation between the mounting portion 1621, the auxiliary stationary contact 1622, and the base 11 helps to improve the assembly accuracy and fixing reliability of the auxiliary stationary spring portion 162 on the base 11. At the same time, the use of a rigid structure for the auxiliary stationary spring portion 162 can prevent the auxiliary stationary spring portion 162 from deforming due to contact with the conductive portion 1612, thus affecting the contact accuracy of the auxiliary contact assembly 16.

[0051] The technical features of the above embodiments can be combined in any way.
