[0037] From the above description of the present disclosure and its preferred embodiments, relative to the prior art, the technical solutions of the present disclosure and its preferred embodiments have the following beneficial effects due to the use of the following technical means:

[0038] The inventor of the present disclosure found through continuous observation, experiment and research that the reason for causing the technical problem of "after setting the auxiliary monitoring switch, the relay is large in size, inconvenient to assemble, the structure of the armature assembly is unstable, the structure of the accommodating piece is relatively complex, the forming is difficult, and the bottom wall is prone to deformation" in the technical solution one of the prior art is that the auxiliary monitoring switch is set in the gap between the armature assembly and the bottom wall, which increases the space of the relay in the rotating shaft direction of the armature assembly, thereby increasing the size of the relay, and also making the rotating shaft of the armature assembly have a larger spacing with the bottom wall, so that the rotating shaft of the armature assembly needs to be set longer and is prone to deformation, thereby reducing the stability of the armature assembly. The auxiliary monitoring switch is installed from the bottom surface, the contact part and the magnetic circuit part are installed from the top surface, the installation directions are different, so the assembly is not convenient, the bottom wall and the first side wall both need to be provided with openings, so the overall strength of the accommodating piece is weak and is prone to deformation, and the openings at different positions also make the mold design of the accommodating piece more difficult, the forming of the accommodating piece is difficult, and the extension length of the lead terminal in this scheme is relatively long, which consumes a lot of materials and is not convenient to connect with the PCB.

[0039] In the technical solution one and the preferred embodiments thereof of the present disclosure, the contact part is adapted to be driven by the armature assembly to be turned on and off along the X-axis direction, and the contact part extends along the Y-axis direction, the coil winding and the contact part are arranged on both sides of the armature assembly along the X-axis direction, and the arrangement is compact, thereby facilitating the reduction of the size of the relay; the coil winding and the contact part extend along the Y-axis direction, on the basis of which, each signal terminal and each connection terminal also extend from the first side wall along the Y-axis direction, the extension path is short, and the complexity and weak strength of the internal circuit of the relay can be avoided; since the first through slot, the second through slot and the third through slot are all opened on the end face of the opening end of the base, each connection terminal extends from the first through slot along the Y-axis direction, each signal terminal extends from the third through slot along the Y-axis direction, and each lead-out terminal extends from the second through slot along the Y-axis direction, therefore, the contact part, the auxiliary monitoring switch and the coil assembly can be placed into the base from the opening end of the base during installation, the installation convenience is improved, and the second through slot and the third through slot on the first side wall can not be opened very long along the Z-axis direction, the weakening of the strength of the first side wall is reduced, the influence of the auxiliary monitoring switch added in the relay on the strength of the first side wall is minimized, thereby ensuring the strength of the first side wall, in addition, the through slots on the other walls of the base do not need to be opened, thereby improving the overall strength of the base and reducing the molding difficulty of the accommodating member. More preferably, it is also beneficial to facilitate the connection of the relay to the PCB along the Y-axis direction. The auxiliary monitoring switch is arranged between the armature assembly and the first side wall along the Y-axis direction and close to the yoke along the X-axis direction, fully utilizes the gap between the armature assembly and the first side wall and the space around the yoke, and installs the auxiliary monitoring switch without the need to increase the size of the accommodating member, thereby reducing the size of the accommodating member. The first through slot, the second through slot and the third through slot are arranged on the first side wall along the X-axis direction in sequence, and the lead-out terminal is located between the connection terminal and the signal terminal along the X-axis direction, thereby facilitating the electrical isolation between the weak electric terminals (including the signal terminal and the lead-out terminal) of the relay and the strong electric terminals (mainly referring to the connection terminal of the contact part) of the relay. Therefore, compared with the prior art solutions one and two, the molding difficulty of the accommodating member is small, the accommodating member is simple to mold, the size of the relay is small, and compared with the prior art one, the gap between the shaft of the armature assembly and the bottom wall is small, the shaft of the armature assembly does not need to be set to be long and is not easy to deform, and the structure of the armature assembly is stable. In addition, the auxiliary monitoring switch in the present technical solution occupies less space compared with the auxiliary monitoring switch standard part, and the position of the terminal of the auxiliary monitoring switch can be adjusted as needed, and the structure design is simpler. In the present technical solution, the connection terminal, the signal terminal and the lead-out terminal all extend along the Y-axis direction, on the one hand, the terminals do not need to be bent complicatedly, the molding difficulty, the material cost are reduced, and the service life is improved, and on the other hand, the wiring path on the PCB is simpler.

[0040] In the second technical solution and the preferred embodiments thereof, the first through-slots are equal in number to the connection terminals and one-to-one correspond to the connection terminals, the second through-slots are equal in number to the lead-out terminals and one-to-one correspond to the lead-out terminals, and the third through-slots are equal in number to the signal terminals and one-to-one correspond to the signal terminals. Compared with the solution in which each connection terminal penetrates through the same first through-slot, each lead-out terminal penetrates through the same second through-slot, and each signal terminal penetrates through the same third through-slot, the first through-slots, the second through-slots, and the third through-slots are smaller, the influence on the strength of the first side wall is weakened, and each corresponding terminal can be better positioned.

[0041] In the third technical solution and the preferred embodiments thereof, each lead-out terminal is arranged along the X-axis direction and close to the open end of the base, and each signal terminal is arranged along the X-axis direction and close to the open end of the base. Compared with the solution in which the lead-out terminals and the signal terminals have a larger distance from the open end of the base, the length of the second through-slots and the third through-slots in the Z-axis direction can be reduced, the influence on the strength of the first side wall is further weakened, and the lead-out terminals and the signal terminals in the Z-axis direction can be better positioned by the shell and the corresponding through-slot bottom.

[0042] In the fourth technical solution and the preferred embodiments thereof, the auxiliary static contact piece is directly fixed to the yoke, the auxiliary static contact piece can be installed and positioned at the same time when the yoke is installed, the problem of needing to install the auxiliary static contact piece again is avoided, assembly is simple, the problem of difficult assembly and positioning of small parts is solved, the problem of easy scratching of the auxiliary static contact piece during installation of the base is also avoided, more preferably, the stability of the yoke and the coil body on the base is utilized to directly support the auxiliary static contact piece by the yoke to obtain strength and stability, so that a mounting portion does not need to be formed on the accommodating member, the structure of the accommodating member is simple, easy to form, and saves materials, and is also beneficial to reducing the volume of the accommodating member and the miniaturization design of the relay to better meet the use requirements and reduce costs. In the technical solution, only one mounting position needs to be provided for the auxiliary static contact piece, and the installation of the auxiliary dynamic contact piece only needs to consider that the auxiliary dynamic contact piece can be reliably separated and other structures that can avoid the armature assembly and the coil assembly, so that the space for installing the auxiliary monitoring switch is effectively reduced without increasing the volume of the accommodating member, thereby providing favorable conditions for installing the auxiliary monitoring switch in a compact space without increasing the volume of the accommodating member.

[0043] In the fifth aspect and the preferred embodiments thereof, the base further comprises a reinforcing portion, which is integrally connected with the first side wall and the bottom wall. The reinforcing portion not only strengthens the first side wall, but also strengthens the bottom wall, thereby improving the overall strength of the base.

[0044] In the sixth aspect and the preferred embodiments thereof, the reinforcing portion is provided with a first support surface and a second support surface, which are perpendicular to the Z-axis direction along the X-axis direction. The first support surface and the second support surface are adapted to support the auxiliary moving contact and the auxiliary stationary contact, respectively, thereby improving the stability of the auxiliary monitoring switch.

[0045] In the seventh aspect and the preferred embodiments thereof, the first side of the auxiliary stationary contact portion is adapted to abut against the auxiliary moving contact, and the second side thereof, which is opposite to the first side, is adapted to abut against the yoke. When the auxiliary moving contact abuts against the auxiliary stationary contact portion, the auxiliary stationary contact portion is supported by the yoke, thereby improving the stability of the auxiliary stationary contact portion in the contact direction of the auxiliary moving contact and ensuring reliable abutment between the auxiliary moving contact and the auxiliary stationary contact.

[0046] In the eighth aspect and the preferred embodiments thereof, the auxiliary stationary contact portion is adapted to abut against and be fixed to the side of the yoke, which is away from the coil winding along the X-axis direction. Compared with being fixed to the side of the yoke, which faces the coil winding, the auxiliary stationary contact portion is more likely to avoid the coil winding, and the distance between the coil winding and the armature assembly along the X-axis direction can be smaller, thereby reducing the occupied space of the relay along the X-axis direction.

[0047] In the ninth aspect and the preferred embodiments thereof, the yoke is provided with a magnetic driving segment, which extends perpendicular to the X-axis direction. The auxiliary stationary contact portion is adapted to abut against and be fixed to the side of the magnetic driving segment, which is away from the coil winding. The magnetic driving segment has a large surface area, which is helpful to improve the connection strength and stability of the auxiliary stationary contact portion after being fixed to the magnetic driving segment. Furthermore, compared with the form of being fixed to the connecting segment of the yoke, the auxiliary monitoring switch occupies less space along the Y-axis direction. The auxiliary moving contact is adapted to be closed or disconnected with the auxiliary stationary contact along the X-axis direction, so that the auxiliary stationary contact can be supported by the magnetic driving segment when the auxiliary moving contact is closed with the auxiliary stationary contact, thereby improving the stability of the structure.

[0048] In the tenth aspect and the preferred embodiments thereof, the auxiliary stationary contact portion is in the form of a flat sheet, which is parallel to the magnetic driving segment. This is helpful to reduce the occupied space of the auxiliary stationary contact portion along the X-axis direction, thereby avoiding interference with the movement of the armature assembly.

[0049] In the eleventh aspect and the preferred embodiments thereof, the connection between the magnetic driving segment and the connecting segment is provided with a circular arc transition surface. The position where the auxiliary stationary contact portion is fixed to the magnetic driving segment avoids the circular arc transition surface, thereby increasing the connection area between the auxiliary stationary contact and the yoke and improving the fixing strength of the auxiliary stationary contact and the yoke.

[0050] In the twelfth aspect and the preferred embodiments thereof, the width direction of the yoke extends along the Z-axis direction; the auxiliary static contact is fixed to the magnetic driving section at a position close to the first end of the yoke away from the bottom wall, and is more likely to avoid the armature assembly in the Z-axis direction and more easily fixed to the yoke compared to being arranged close to the middle of the yoke.

[0051] In the thirteenth aspect and the preferred embodiments thereof, the magnetic driving section is provided with a protruding portion protruding along the Z-axis direction at the first end of the yoke, and the auxiliary static contact is at least partially fixed to the protruding portion, which on the one hand makes the auxiliary static contact more likely to avoid the armature assembly in the Z-axis direction, and on the other hand makes the fixed position more likely to avoid the arc transition surface of the yoke, so that the connection between the auxiliary static contact and the yoke is more stable, and in addition, the auxiliary static contact and the yoke have a larger connection area and higher fixed strength.

[0052] In the fourteenth aspect and the preferred embodiments thereof, an avoiding gap suitable for avoiding the armature assembly is formed between the first connecting portion and the second connecting portion; the second connecting portion is closer to the bottom wall than the first connecting portion; in the Y-axis direction, the second connecting portion is closer to the arc transition surface of the yoke than the first connecting portion; the first connecting portion is fixed to the yoke; and the auxiliary static contact is arranged on the second connecting portion, which on the one hand makes the auxiliary static contact more likely to avoid the armature assembly in the Y-axis direction and the Z-axis direction, and on the other hand makes the first connecting portion more distant from the arc transition surface of the yoke, thereby improving the connection stability of the first connecting portion and the yoke; in addition, arranging the second connecting portion closer to the arc transition surface is conducive to avoiding interference of the second connecting portion with the movement of the armature assembly.

[0053] In the fifteenth aspect and the preferred embodiments thereof, the auxiliary static contact is further provided with a static lead-out terminal and a bending portion extending along the X-axis direction, which is connected between the first connecting portion and the static lead-out terminal and located on one side of the connecting section along the Z-axis direction, which on the one hand makes full use of the space on one side of the connecting section along the Z-axis direction to avoid the auxiliary static contact expanding the occupied space of the relay in the Z-axis direction, and on the other hand makes the static lead-out terminal close to the coil assembly, thereby more conducive to achieving electrical isolation between the weak current terminals of the relay (including the terminals of the coil assembly and the auxiliary monitoring switch) and the strong current terminals of the relay (mainly referring to the connecting terminals of the contact portion below), and in addition, connecting the static lead-out terminal to the bending portion is conducive to saving the length of the bending portion and saving materials and costs.

[0054] In the sixteenth aspect and the preferred embodiments thereof, when the auxiliary movable contact is in contact with the auxiliary stationary contact, the auxiliary stationary contact has an electrical path, the position where the auxiliary stationary contact is fixed to the magnetic driving section is located outside the electrical path, and the current does not pass through the position where the auxiliary stationary contact is fixed to the magnetic driving section to enter the yoke when the auxiliary monitoring switch is closed, so that the influence of the current of the auxiliary monitoring switch on the magnetic loop in the yoke can be avoided without the need to set an insulation structure between the auxiliary stationary contact and the magnetic driving section, and the complexity of the structure is reduced.

[0055] In the seventeenth aspect and the preferred embodiments thereof, the auxiliary stationary contact further comprises a stationary lead terminal and a bending portion, the bending portion extends along the X-axis direction, is connected between the auxiliary stationary portion and the stationary lead terminal, and is located on one side of the connection section along the Z-axis direction, on the one hand, the space on the one side of the connection section along the Z-axis direction is fully utilized to avoid the auxiliary stationary contact from expanding the occupied space of the relay in the Z-axis direction, and on the other hand, the stationary lead terminal is close to the coil assembly, so that the electrical isolation between the weak current terminals (including the terminals of the coil assembly and the terminals of the auxiliary monitoring switch) of the relay and the strong current terminals (mainly the connection terminals of the contact part) of the relay is more conducive to be achieved, and in addition, the stationary lead terminal is connected to the bending portion, so that the length of the bending portion is saved, and the material and cost are saved.

[0056] In the eighteenth aspect and the preferred embodiments thereof, the auxiliary stationary contact is located between the position where the auxiliary stationary portion is fixed to the magnetic driving section and the circular-arc transition surface along the Y-axis direction, so that the position where the auxiliary stationary contact is fixed to the magnetic driving section is located outside the electrical path, and the fixed position is further away from the circular-arc transition surface of the yoke, and the connection between the auxiliary stationary contact and the yoke is more stable.

[0057] In the nineteenth aspect and the preferred embodiments thereof, the magnetic driving section of the yoke is punched to form an installation groove with an opening away from the coil winding and a riveting portion protruding from the installation groove, the auxiliary stationary contact is installed in the installation groove and is provided with a riveting hole matched with the riveting portion, the riveting portion can have a greater length in the X-axis direction through the punching process, so that the auxiliary stationary contact can have a greater thickness, and the occupied space in the X-axis direction is small when the auxiliary stationary contact is applied to the relay.

[0058] In the twentieth aspect and the preferred embodiments thereof, the auxiliary stationary contact is riveted to the yoke, the process is simpler, and the structure is stable.

[0059] In the twenty-first aspect and the preferred embodiments thereof, the riveting hole is a counterbore, and the riveting portion does not protrude out of the riveting hole, so that the occupied space of the auxiliary stationary portion in the X-axis direction is more reduced.

[0060] In technical solution twenty-two and preferred embodiments thereof, the reinforcing portion is provided with a first limiting groove, the auxiliary movable contact is provided with a fixed portion and a swing portion, the fixed portion is fixedly inserted into the first limiting groove along the Z-axis direction, so that the reinforcing portion can not only strengthen the overall strength of the base, but also limit the fixed portion of the auxiliary movable contact, thereby eliminating the need to separately provide a positioning structure for the auxiliary movable contact, and reducing the difficulty of forming the base.

[0061] In technical solution twenty-three and preferred embodiments thereof, the reinforcing portion further cooperates with the first side wall to form a second limiting groove extending along the X-axis direction, and the auxiliary movable contact is further provided with a movable lead-out portion connected between the fixed portion and a movable lead-out terminal and limited in the second limiting groove along the Y-axis direction, which is conducive to extending the movable lead-out terminal along the Y-axis direction, and thus makes the cooperation structure of the auxiliary movable contact and the base more, and is more conducive to improving the stability of the movable lead-out terminal. The movable lead-out portion is located on the side of the fixed portion facing the auxiliary static contact, so that the movable lead-out terminal can be close to the static lead-out terminal, which is conducive to improving the electrical isolation effect of the connection terminal.

[0062] In technical solution twenty-four and preferred embodiments thereof, the movable lead-out portion is a flat sheet perpendicular to the Y-axis direction, which is conducive to reducing the occupied space of the movable lead-out portion in the Y-axis direction, thereby providing favorable conditions for installing the auxiliary monitoring switch in a compact space.

[0063] In technical solution twenty-five and preferred embodiments thereof, the auxiliary movable contact is provided with an auxiliary movable spring extending along the Z-axis direction. Compared with the auxiliary movable spring extending along the Y-axis direction, the auxiliary monitoring switch occupies less space in the Y-axis direction, and since the fixed portion is fixedly inserted into the first limiting groove, the length between the swing portion and the fixed end of the auxiliary movable spring is longer, which is more conducive to reducing the stress concentration phenomenon of the auxiliary movable spring and improving the service life. The auxiliary movable spring is a sheet structure with a thickness direction extending along the X-axis direction, which is conducive to reducing the space occupation of the auxiliary movable spring in the X-axis direction, and is further conducive to installing the auxiliary movable contact in a compact space.

[0066] In technical solution twenty-eight and preferred embodiments thereof, generally, if the armature assembly drives the moving contact member to move by driving a separate push card, the area on the side of the yoke iron along the X-axis direction towards the contact part is generally used as the moving space of the push card, if the auxiliary monitoring switch needs to be installed on the side of the armature along the Y-axis direction, a swing arm needs to be led out from the armature assembly to push the auxiliary monitoring switch, and the swing arm also needs to bypass the armature in the armature assembly, resulting in a more complex structure, large material consumption and large volume occupation. In the present technical solution, the driving member has an integrally formed driving part and auxiliary pushing part, the driving member is integrally formed with the insulating member, and the insulating member is fixedly connected with the permanent magnet, so that by reasonable design and processing, the driving part can avoid the space for installing the auxiliary monitoring switch, and the auxiliary pushing part with small structure is also used to drive the auxiliary moving contact member in the auxiliary monitoring switch to move, so that the structure is simple, the material consumption is small, the forming is good, and the volume of the relay does not need to be increased. In the present technical solution, the driving part and the auxiliary pushing part are integrally arranged on the driving member, so that the structure is simple, the forming is easy, and the production cost is reduced. In addition, the driving part and the auxiliary pushing part are stable relative to the armature assembly, so that the moving contact member and the auxiliary moving contact member can be reduced in shaking when breaking, the burning characteristics of the breaking arc are avoided from being affected, the contact point burning and the uncontrolled arc burning of other parts are reduced, and the like.

The stationary lead-out terminal 03 and the moving lead-out terminal 04 form two lead-out terminals of the auxiliary monitoring switch 300. Therefore, the stationary lead-out terminal 03 and the moving lead-out terminal 04 both extend along the Y-axis direction and are flush in the Z-axis direction. In this embodiment, the stationary lead-out terminal 03 and the moving lead-out terminal 04 respectively pass through two second through grooves 1122 of the first side wall 112.

[0116] The auxiliary static contact 60 is fixed to the yoke 23 close to the first side wall 112, that is, the second magnetic driving section 235, the coil assembly 20 is placed into the second slot 115, and the signal terminal 01 of the coil assembly 20 penetrates the second through slot 1122, the coil winding 22 abuts against the limiting strip 1152, the two yokes 23 are respectively inserted into the two second positioning slots 1151, and the static lead-out terminal 03 of the auxiliary static contact 60 penetrates the other second through slot 1122 of the first side wall 112; at this time, the relay can refer to FIG. 4, FIG. 7 and FIG. 9;

[0117] Subsequently, the base 11 is sleeved into the shell 12 along the Y-axis direction and is fixedly connected with the shell 12. It should be understood that the sequence of each part in the installation process can be adjusted as needed.

[0118] After the installation is completed, the contact part 200 and the coil winding 22 are respectively located on both sides of the first plane in the X-axis direction, the first plane is perpendicular to the X-axis direction and passes through the rotation axis, and the permanent magnet is located between the two yokes 23 in the Y-axis direction. Referring to FIG. 9, the upper ends of the signal terminal 01, the static lead-out terminal 03 and the movable lead-out terminal 04 are located at the same height in the Z-axis direction, and are located on the side close to the opening of the first side wall 112.

[0119] The working process of the embodiment is as follows:

[0120] When the signal terminal 01 receives the first pulse signal, the armature assembly 30 rotates from the second position to the first position, as shown in FIG. 4, one first attraction part 321 attracts the first magnetic driving section 234, one second attraction part 331 attracts the second magnetic driving section 235, and the driving part 81 drives the movable contact 411 to close with the static contact 51; the auxiliary pushing part 82 drives the auxiliary movable contact 7111 to open with the auxiliary static contact 613.

[0121] When the signal terminal 01 receives the pulse signal, the armature assembly 30 rotates from the first position to the second position, as shown in FIG. 7, the other second attraction part 331 attracts the first magnetic driving section 234, the other first attraction part 321 attracts the second magnetic driving section 235, and the driving part 81 drives the movable contact 411 to open with the static contact 51; the auxiliary pushing part 82 drives the auxiliary movable contact 7111 to close with the auxiliary static contact 613.

[0122] In the embodiment, the contact portion 200 is suitable for being driven by the armature assembly 30 to be turned on and off along the X-axis direction, and the contact portion 200 extends along the Y-axis direction, the coil winding 22 and the contact portion 200 are arranged on both sides of the armature assembly 30 along the X-axis direction, and the arrangement is compact, thereby facilitating the reduction of the size of the relay; the coil winding 22 and the contact portion 200 extend along the Y-axis direction, on this basis, each signal terminal 01 and each connection terminal 02 also extend from the first side wall 112 along the Y-axis direction, the extension path is short, and the internal circuit of the relay can be prevented from being complex and weak in strength; since the first through slot 1121, the second through slot 1122 and the third through slot 1123 are all opened on the end face of the opening end of the base 11, each connection terminal 02 extends from the first through slot 1121 along the Y-axis direction, each signal terminal 01 extends from the third through slot 1123 along the Y-axis direction, and each lead-out terminal extends from the second through slot 1122 along the Y-axis direction, therefore, the contact portion 200, the auxiliary monitoring switch 300 and the coil assembly 20 can be placed into the base 11 from the opening end of the base 11 during installation, the installation convenience is improved, and the second through slot 1122 and the third through slot 1123 on the first side wall 112 can not be opened along the Z-axis direction for a long time, the weakening of the strength of the first side wall 112 is reduced, the influence of the auxiliary monitoring switch 300 on the strength of the first side wall 112 is minimized when the auxiliary monitoring switch 300 is additionally arranged in the relay, and the strength of the first side wall 112 is ensured, in addition, the through slots do not need to be additionally arranged on the other walls of the base 11, thereby the strength of the whole base 11 is improved and the forming difficulty of the accommodating member 10 is reduced. More preferably, the relay is conveniently connected to the PCB along the Y-axis direction. The auxiliary monitoring switch 300 is arranged between the armature assembly 30 and the first side wall 112 along the Y-axis direction and close to the yoke 23 along the X-axis direction, the gap between the armature assembly 30 and the first side wall 112 and the space around the yoke 23 are fully utilized, and the auxiliary monitoring switch 300 is installed without the need to increase the size of the accommodating member 10, thereby the size of the accommodating member 10 is reduced. The first through slot 1121, the second through slot 1122 and the third through slot 1123 are arranged on the first side wall 112 along the X-axis direction in sequence, and the lead-out terminal is located between the connection terminal 02 and the signal terminal 01 along the X-axis direction, thereby the electrical isolation between the weak electric terminals (including the signal terminal 01 and the lead-out terminal) of the relay and the strong electric terminals (mainly referring to the connection terminal 02 of the contact portion 200) of the relay is facilitated. Therefore, compared with the prior art one and the prior art two, the forming difficulty of the accommodating member 10 is small, the accommodating member 10 is simple in forming, the size of the relay is small, and compared with the prior art one, there is not much gap between the rotation shaft of the armature assembly 30 and the bottom wall 111, the rotation shaft of the armature assembly 30 does not need to be arranged for a long time and is not easy to be deformed, and the structure of the armature assembly 30 is stable.In addition, the auxiliary monitoring switch 300 in the embodiment occupies less space compared with the auxiliary monitoring switch 300 standard part, and the positions of the terminals of the auxiliary monitoring switch 300 can be adjusted as required, and the structural design is simpler. In the embodiment, the connection terminals 02, the signal terminals 01 and the lead-out terminals all extend along the Y-axis direction, on the one hand, so that each terminal does not need to be bent complicatedly, which reduces the molding difficulty, the material cost and improves the service life, and on the other hand, the wiring path on the PCB board is simpler.

[0123] In the embodiment, the first through grooves 1121 are equal in number to the connection terminals 02 and one-to-one corresponding, the second through grooves 1122 are equal in number to the lead-out terminals and one-to-one corresponding, and the third through grooves 1123 are equal in number to the signal terminals 01 and one-to-one corresponding. Compared with the scheme that each connection terminal 02 penetrates through the same first through groove 1121, each lead-out terminal penetrates through the same second through groove 1122, and each signal terminal 01 penetrates through the same third through groove 1123, the first through groove 1121, the second through groove 1122 and the third through groove 1123 are smaller, which weakens the influence on the strength of the first side wall 112, and each corresponding terminal can be better positioned.

[0124] In the embodiment, each lead-out terminal is arranged along the X-axis direction and close to the open end of the base 11, and each signal terminal 01 is arranged along the X-axis direction and close to the open end of the base 11. Compared with the scheme that the lead-out terminal and the open end of the base 11 and the signal terminal 01 and the open end of the base 11 have a larger distance, the length of the second through groove 1122 and the third through groove 1123 in the Z-axis direction can be reduced, thereby further weakening the influence on the strength of the first side wall 112, and the lead-out terminal and the signal terminal 01 in the Z-axis direction are limited by the shell 12 and the corresponding groove bottom of the through groove.

[0125] In the embodiment, the base 11 further comprises a reinforcing portion 116, and the reinforcing portion 116 is integrally connected with the first side wall 112 and the bottom wall 111. The reinforcing portion 116 not only strengthens the strength of the first side wall 112, but also strengthens the strength of the bottom wall 111, thereby improving the overall strength of the base 11.

[0126] In the embodiment, the yoke 23 is usually fixed to the end face of the coil winding 22 and is fixedly inserted into the accommodating member 10 together with the coil winding 22. In the embodiment, the auxiliary monitoring switch 300 is arranged close to the yoke 23 along the X-axis direction, and therefore the auxiliary static contact 60 is directly fixed to the yoke 23, which can be simultaneously installed and positioned when the yoke 23 is installed, avoiding the problem of needing to install the auxiliary static contact 60 again, and facilitating assembly, thereby solving the problem of difficult assembly and positioning of small parts. In addition, the problem of easy scratching of the auxiliary static contact 60 when being installed on the base 11 can be avoided. More preferably, the stability of the yoke 23 and the coil body on the base 11 is utilized, so that the auxiliary static contact 60 is directly supported by the yoke 23 to obtain strength and stability, thereby eliminating the need to form a mounting portion on the accommodating member 10, so that the structure of the accommodating member 10 is simple, easy to form and saves materials. In addition, it is also beneficial to reduce the volume of the accommodating member 10 and the miniaturization design of the relay to better meet the use requirements and reduce costs. In the embodiment, since the auxiliary moving contact 70 only needs to be installed on the base 11, as long as the auxiliary moving contact 70 can avoid other structures of the armature assembly 30 and the coil assembly 20, the space required by the auxiliary monitoring switch 300 in the accommodating member 10 is smaller, thereby providing favorable conditions for installing the auxiliary monitoring switch 300 in a compact space without increasing the volume of the accommodating member 10.

[0127] In the embodiment, the reinforcing portion 116 is provided with a first support surface 1163 and a second support surface 1164 perpendicular to the Z-axis direction along the X-axis direction, and the first support surface 1163 and the second support surface 1164 are respectively adapted to support the auxiliary moving contact 70 and the auxiliary static contact 60, thereby improving the stability of the auxiliary monitoring switch 300.

[0128] In the embodiment, the first side of the auxiliary static contact portion 61 is used to abut against the auxiliary moving contact 70, and the second side thereof away from the auxiliary moving contact 70 abuts against the yoke 23. When the auxiliary moving contact 70 abuts against the auxiliary static contact portion 61, the auxiliary static contact portion 61 is supported by the yoke 23, further improving the stability of the auxiliary static contact 60 in the contact direction of the auxiliary moving contact 70, and making the abutment between the auxiliary moving contact 70 and the auxiliary static contact 60 reliable.

[0129] In the embodiment, the auxiliary static contact portion 61 abuts against and is fixed to the side of the yoke 23 away from the coil winding 22 along the X-axis direction. Compared with being fixed to the side of the yoke 23 facing the coil winding 22, the auxiliary static contact 60 is more easily avoided from the coil winding 22, and the distance between the coil winding 22 and the armature assembly 30 (along the X-axis direction) can not be too large, thereby reducing the occupied space of the relay in the X-axis direction.

[0130] In the embodiment, the yoke 23 is provided with a magnetic driving segment 231 extending perpendicularly to the X-axis direction, and the auxiliary static contact portion 61 is fixed to the side of the magnetic driving segment 231 away from the coil winding 22. The magnetic driving segment 231 has a large surface area, which helps to improve the connection strength and stability of the auxiliary static contact 60 after being fixed to the magnetic driving segment 231. In addition, compared with the form that the auxiliary static contact 60 is fixed to the connecting segment 232 of the yoke 23, the auxiliary monitoring switch 300 occupies less space in the Y-axis direction. The auxiliary moving contact 7111 is adapted to be closed or disconnected with the auxiliary static contact 613 in the X-axis direction, so that when the auxiliary moving contact 7111 is closed with the auxiliary static contact 613, the auxiliary static contact 613 can be supported by the magnetic driving segment 231, and the structure is more stable.

[0131] In the embodiment, the auxiliary static contact portion 61 is a flat sheet parallel to the magnetic driving segment 231, which is beneficial to reduce the occupation space of the auxiliary static contact portion 61 in the X-axis direction, so as to avoid interference with the movement of the armature assembly 30.

[0132] In the embodiment, the connection between the magnetic driving segment 231 and the connecting segment 232 has a circular arc transition surface 233, and the position where the auxiliary static contact portion 61 is fixed to the magnetic driving segment 231 avoids the circular arc transition surface 233, so that the auxiliary static contact 60 and the yoke 23 have a larger connection area, and the fixing strength of the auxiliary static contact 60 and the yoke 23 is improved.

[0133] In the embodiment, the width direction of the yoke 23 extends along the Z-axis direction; the position where the auxiliary static contact portion 61 is fixed to the magnetic driving segment 231 is close to the first end of the yoke 23 away from the bottom wall 111, compared with being arranged close to the middle part of the yoke 23, the auxiliary static contact 60 is more easily avoided in the Z-axis direction with the armature assembly 30, and the fixing operation of the auxiliary static contact 60 and the yoke 23 is also easier to implement.

[0134] In the embodiment, at the first end of the yoke 23, the magnetic driving segment 231 is provided with a protruding portion 2311 protruding in the Z-axis direction relative to the connecting segment 232, and the auxiliary static contact portion 61 is at least partially fixed to the protruding portion 2311. On the one hand, the auxiliary static contact 60 is more easily avoided in the Z-axis direction with the armature assembly 30, on the other hand, the fixing position is more easily avoided from the circular arc transition surface 233 of the yoke 23, so that the connection of the auxiliary static contact 60 and the yoke 23 is more stable, in addition, the auxiliary static contact 60 and the yoke 23 also have a larger connection area, and the fixing strength is improved.

[0135] In this embodiment, the first connecting portion 611 and the second connecting portion 612 form an avoiding gap 614 suitable for avoiding the armature assembly 30; the second connecting portion 612 is farther away from the first end of the yoke 23 than the first connecting portion 611; in the Y-axis direction, the second connecting portion 612 is closer to the arc transition surface 233 of the yoke 23 than the first connecting portion 611; the first connecting portion 611 is fixedly connected to the yoke 23; the auxiliary static contact 613 is arranged on the second connecting portion 612, which on the one hand makes the auxiliary static contact 60 more easily avoid the armature assembly 30 in the Y-axis direction and the Z-axis direction, and on the other hand makes the first connecting portion 611 can be farther away from the arc transition surface 233 of the yoke 23, thereby improving the connection stability of the first connecting portion 611 and the yoke 23; in addition, arranging the second connecting portion 612 closer to the arc transition surface 233 is conducive to avoiding interference of the second connecting portion 612 with the movement of the armature assembly 30.

[0136] In this embodiment, the auxiliary static contact 60 is also provided with a static lead-out terminal 03 and a bending portion 62, the bending portion 62 extends along the X-axis direction and is connected between the first connecting portion 611 and the static lead-out terminal 03 and located on one side of the connecting section 232 in the Z-axis direction, on the one hand, the space on one side of the connecting section 232 in the Z-axis direction is fully utilized to avoid the auxiliary static contact 60 expanding the occupied space of the relay in the Z-axis direction; on the other hand, the static lead-out terminal 03 is close to the coil assembly 20, thereby being more conducive to realizing the electrical isolation between the weak current terminals of the relay (including the terminals of the coil assembly 20 and the terminals of the auxiliary monitoring switch 300) and the strong current terminals of the relay (here mainly refers to the connecting terminal 02 of the contact portion 200), in addition, the static lead-out terminal 03 is connected to the bending portion 62, which is conducive to saving the length of the bending portion 62, saving materials and costs.

[0137] In this embodiment, the auxiliary static contact 60 is riveted to the yoke 23, which is simpler in process and stable in structure.

[0138] In this embodiment, the riveting hole 6111 is a counterbore, and the riveting portion 2351 does not protrude out of the riveting hole 6111, which is more conducive to reducing the occupied space of the auxiliary static contact 61 in the X-axis direction.

[0139] In this embodiment, the reinforcing portion 116 is provided with a first limiting groove 1161, and the auxiliary moving contact 70 is provided with a fixed portion 73 and a swinging portion 711, the fixed portion 73 is fixedly inserted into the first limiting groove 1161 in the Z-axis direction, so that the reinforcing portion 116 can not only strengthen the overall strength of the base 11, but also limit the fixed portion 73 of the auxiliary moving contact 70, thereby eliminating the need for a separate positioning structure for the auxiliary static contact, reducing the difficulty of forming the base 11.

[0140] In the embodiment, the reinforcing portion 116 also cooperates with the first side wall 112 to form a second limiting groove 1162 extending along the X-axis direction, and the movable lead-out portion 74 is arranged on the auxiliary movable contact 70, and the movable lead-out portion 74 is connected with the fixed portion 73 and the movable lead-out terminal 04 and is limited in the second limiting groove 1162 along the Y-axis direction, which is beneficial to the extension of the movable lead-out terminal 04 along the Y-axis direction, and thus the cooperation structure of the auxiliary movable contact 70 and the base 11 is more, which is more beneficial to improve the stability of the movable lead-out terminal 04. The movable lead-out portion 74 is located on the side of the fixed portion 73 facing the auxiliary static contact 60, so that the movable lead-out terminal 04 can be close to the static lead-out terminal 03, which is beneficial to improve the electrical isolation effect of the connection terminal 02.

[0141] In the embodiment, the movable lead-out portion 74 is a flat sheet perpendicular to the Y-axis direction, which is beneficial to reduce the space occupied by the movable lead-out portion 74 in the Y-axis direction, thereby providing favorable conditions for installing the auxiliary monitoring switch 300 in a compact space.

[0142] In the embodiment, the auxiliary movable contact 70 is provided with an auxiliary movable spring 71 extending along the Z-axis direction. Compared with the auxiliary movable spring 71 extending along the Y-axis direction, the auxiliary monitoring switch 300 occupies less space in the Y-axis direction, and since the fixed portion 73 is fixedly inserted into the first limiting groove 1161, the length between the swing portion 711 and the fixed end of the auxiliary movable spring 71 is longer, which is more beneficial to reduce the stress concentration phenomenon of the auxiliary movable spring 71 and improve the service life. The auxiliary movable spring 71 is a sheet structure with the thickness direction extending along the X-axis direction, which is beneficial to reduce the space occupied by the auxiliary movable spring 71 in the X-axis direction, and further beneficial to install the auxiliary movable contact 70 in a compact space.
