[0043] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0044] like Figure 1As shown, the magnetic latching relay of the embodiment of the utility model comprises a base 1, a fixing frame 3, a monitoring dynamic spring 5 and a monitoring static spring 6. Among them, the fixing frame 3 is assembled on the base 1. The fixing frame 3 is provided with an insertion structure 4, the insertion structure 4 has an insertion space, and the insertion structure 4 comprises a first partition 41, the first partition 41 is arranged in the insertion space, and the first partition 41 is provided with a first glue dispensing port 43 and a second glue dispensing port 44 connected with the insertion space.

[0045] like Figure 2 and Figure 3 As shown, the monitoring movable spring 5 and the monitoring static spring 6 are inserted into the insertion space along the vertical direction Z, the monitoring movable spring 5 extends from the first glue dispensing port 43, and the monitoring static spring 6 extends from the second glue dispensing port 44. The first glue dispensing port 43 and the second glue dispensing port 43 are used for dispensing to fix the monitoring movable spring 5 and the monitoring static spring 6. Among them, the monitoring movable spring 5 and the monitoring static spring 6 are used to monitor the open and closed states of the magnetic latching relay.

[0046] In the embodiment of the utility model, since the first dispensing port 43 and the second dispensing port 44 are both provided on the first partition 41, when dispensing, it is only necessary to move the dispensing head in the same plane, making the dispensing operation simpler and more convenient. At the same time, the glue flows from the dispensing port along the monitoring movable spring 5 and the monitoring static spring 6, fixing the monitoring movable spring 5 and the monitoring static spring 6, improving the stability of the bonding, and further improving the stability of the monitoring movable spring 5 and the monitoring static spring 6 in monitoring the magnetic latching relay.

[0047] like Figure 4 As shown, the magnetic latching relay of the embodiment of the utility model further includes a cover 10 , which covers the base 1 . The base 1 has a receiving space for arranging various components of the magnetic latching relay. The cover 10 can protect the components in the base 1 .

[0048] like Figure 1 as well as Figures 5 to 7 As shown, the magnetic latching relay further includes a coil assembly 7, a magnetic circuit assembly 2 and a contact assembly 8, which are arranged on the base 1 and placed in the accommodation space. The coil assembly 7 includes a coil frame 71, an iron core (not shown in the figure) and a coil 72, wherein the iron core is arranged in the coil frame 71 and the coil 72 is wound on the surface of the coil frame 71.

[0049] The magnetic circuit assembly 2 is arranged on the base 1 and can swing in the first horizontal direction X. In the embodiment of the utility model, Figure 5 and Figure 7As shown, the magnetic circuit assembly 2 may include a permanent magnet (not shown in the figure), an armature 22 and an injection molded part 23. The armature 22 is arranged on the permanent magnet, and the injection molded part 23 is coated on the permanent magnet and part of the armature 22, so that the permanent magnet and the armature 22 are fixedly connected, and the armature 22 protrudes from the permanent magnet along the second horizontal direction Y. The injection molded part 23 is swingably connected to the base 1, that is, the injection molded part 23 is provided with a rotating shaft, and the base 1 is provided with a first shaft hole (not shown in the figure), and one end of the rotating shaft of the injection molded part 23 is connected to the first shaft hole and can rotate in the first shaft hole. Figure 5 As shown, the injection molded part 23 also includes an integrally molded swing arm 232 .

[0050] The magnetic circuit assembly 2 may further include a first yoke 24 and a second yoke 25 . The first yoke 24 and the second yoke 25 are located in the base 1 and at two ends of the coil assembly 7 , and are respectively connected to two ends of the iron core.

[0051] Continue to refer Figure 1 and Figure 5 The contact assembly 8 includes a moving spring 81 and a stationary spring 82. The moving spring 81 is provided with a moving contact 811, and the stationary spring 82 is provided with a stationary contact 821. The moving contact 811 and the stationary contact 821 are correspondingly arranged in the first horizontal direction X. Figure 5 As shown, the magnetic latching relay also includes a dynamic spring lead-out terminal 812 and a static spring lead-out terminal 822, which are respectively arranged outside the base 1, and the dynamic spring lead-out terminal 812 is connected to the dynamic spring piece 81, and the static spring lead-out terminal 822 is connected to the static spring piece 82, so as to realize the connection between the dynamic spring piece 81 and the static spring piece 82 and the load circuit.

[0052] like Figure 5 As shown, the magnetic latching relay of the utility model embodiment further includes a push card 9, which is movably arranged on the base 1. One end of the push card 9 is connected to the swing arm 232 of the injection molded part 23, and the other end is connected to one end of the moving reed 81 provided with a moving contact 811.

[0053] When a positive voltage is applied to the coil 72, the permanent magnet of the magnetic circuit assembly 2 swings to one side in the first horizontal direction X, and at the same time drives the armature 22 to swing, and the armature 22 overlaps with the first yoke 24 and the second yoke 25, so that the permanent magnet, the armature 22, the first yoke 24, the iron core and the second yoke 25 form a constant magnetic field. At the same time, the swing arm 232 of the injection molded part 23 swings in the same direction as the permanent magnet, and the swing arm 232 drives the push card 9 to move in the first horizontal direction X, and the push card 9 drives the moving spring 81 to move in the direction close to the static spring 82, so that the moving contact 811 and the static contact 821 are closed (such as Figure 6 and Figure 7As shown in FIG. 1 ), the magnetic latching relay is closed and the external load circuit is turned on. When the coil 72 is powered off, the permanent magnet can maintain the constant magnetic field, thereby maintaining the position of the swing arm 232, thereby maintaining the moving and static contacts in a closed state, and keeping the magnetic latching relay in a closed state.

[0054] When a reverse voltage is applied to the coil 72, the permanent magnet swings in the opposite direction to the other side in the first horizontal direction X, and drives the armature 22 to swing in the other direction at the same time. The armature 22 overlaps with the first yoke 24 and the second yoke 25, forming another reverse constant magnetic field. At the same time, the swing arm 232 of the injection molded part 23 swings with the permanent magnet, and the swing arm 232 drives the push card 9 to move in the opposite direction in the first horizontal direction X. The push card 9 drives the moving spring 81 to move away from the static spring 82, so that the moving contact 811 is disconnected from the static contact 821 (such as Figure 1 and Figure 5 As shown in FIG. 1 , the magnetic latching relay is disconnected and the external load circuit is disconnected. When the coil 72 is powered off, the permanent magnet can maintain the reverse constant magnetic field, thereby maintaining the position of the swing arm 232, thereby maintaining the moving and static contacts in the disconnected state, and the magnetic latching relay is in the disconnected state.

[0055] The above is an explanation of the partial structure of the magnetic latching relay and the principle of closing and opening of the magnetic latching relay. The opening and closing of the magnetic latching relay can be understood as the opening and closing of the moving contact 811 and the static contact 821. When the magnetic latching relay is actually used, it is usually necessary to monitor the closing and opening states of the magnetic latching relay to ensure the safety of the load circuit. In the embodiment of the utility model, the state of the magnetic latching relay is monitored by monitoring the closing and opening states of the moving spring 5 and the static spring 6.

[0056] like Figure 1 and Figure 6 As shown, the fixing frame 3 covers at least a portion of the magnetic circuit assembly 2. The fixing frame 3 is used to fix the magnetic circuit assembly 2 to the base 1 and to limit the position of the magnetic circuit assembly 2 in the vertical direction Z so that the magnetic circuit assembly 2 can swing smoothly in the base 1. Figure 1 The fixing frame 3 is provided with a second shaft hole 31, and the other end of the rotating shaft of the injection molded part 23 is connected to the second shaft hole 31 and can rotate in the second shaft hole 31. The fixing frame 3 is provided with a column, and the corresponding position of the base 1 is provided with a socket, and the column of the fixing frame 3 is inserted into the socket to achieve a fixed connection between the fixing frame 3 and the base 1. Since the fixing frame 3 can cover at least part of the magnetic circuit component 2 in the vertical direction Z, the fixing frame 3 can limit the magnetic circuit component 2 in the vertical direction Z to prevent the magnetic circuit component 2 from being misplaced in the vertical direction Z and affecting its normal swing.

[0057] It should be noted that the first horizontal direction X, the second horizontal direction Y and the vertical direction Z in the embodiment of the present invention are respectively perpendicular to each other, and the first horizontal direction X, the second horizontal direction Y and the vertical direction Z are merely technical terms indicating different directions and have no special limiting meaning.

[0058] like Figure 1 and Figure 2 As shown, the insertion structure 4 is located on one side of the magnetic circuit assembly 2 in the first horizontal direction X, so after the monitoring dynamic spring 5 and the monitoring static spring 6 are inserted into the insertion space, they are also located on one side of the magnetic circuit assembly 2 in the first horizontal direction X.

[0059] When the first voltage is applied, the magnetic circuit assembly 2 moves to one side in the first horizontal direction X, driving the end of the monitoring movable spring 5 to close with the end of the monitoring static spring 6. When the second voltage opposite to the first voltage is applied, the magnetic circuit assembly 2 moves to the other side, and the end of the monitoring movable spring 5 is disconnected from the end of the monitoring static spring 6.

[0060] In the embodiment of the utility model, the plug-in structure 4 is arranged on the fixing frame 3, which can simplify the assembly, further improve the accuracy and reliability of monitoring, and reduce the volume of the entire relay, which is conducive to miniaturization.

[0061] Since the moving spring piece 81 and the monitoring moving spring 5 are both driven by the magnetic circuit assembly 2, the movement of the monitoring moving spring 5 and the moving spring piece 81 is synchronized, and the closing and opening states of the monitoring moving spring 5 and the monitoring static spring 6 can be used to monitor the closing and opening states of the moving spring piece 81 and the static spring piece 82. For example, when the monitoring moving spring 5 and the monitoring static spring 6 are in the closed state, the moving spring piece 81 and the static spring piece 82 are in the open state or the closed state, and when the monitoring moving spring 5 and the monitoring static spring 6 are in the open state, the moving spring piece 81 and the static spring piece 82 are in the closed state or the open state.

[0062] In some embodiments, the first voltage and the second voltage may be pulse voltages in opposite directions.

[0063] like Fig. 9 and Fig.11 As shown, Fig.11 FIG. 1 is a schematic diagram of a side of the fixing frame 3 facing the base 1, and FIG. Fig. 9 In the embodiment of the utility model, at least part of the inner peripheral wall of the first dispensing port 43 is tilted, so that the radial dimension of the first dispensing port 43 gradually decreases from the top to the bottom of the first dispensing port 43. At least part of the inner peripheral wall of the second dispensing port 44 is tilted, so that the radial dimension of the second dispensing port 44 gradually decreases from the top to the bottom of the second dispensing port 44. In this way, the first dispensing port 43 and the second dispensing port 44 can be roughly funnel-shaped.

[0064] Among them, the top end of the first glue dispensing port 43 refers to the end of the first glue dispensing port 43 away from the base 1 in the vertical direction Z, and the bottom end refers to the end of the first glue dispensing port 43 close to the base 1 in the vertical direction Z. The top end and the bottom end of the second glue dispensing port 44 can be understood in the same way.

[0065] In some embodiments, Fig.11 As shown, the first dispensing port 43 and the second dispensing port 44 are provided with a plurality of wedge-shaped protrusions 47 on the inner wall, so that the radial dimension of the inner circumferential wall of the first dispensing port 43 and the second dispensing port 44 gradually decreases from the top end to the bottom end.

[0066] The first glue dispensing port 43 and the second glue dispensing port 44 are funnel-shaped, which is conducive to the glue liquid flowing downward to the monitoring movable spring 5 and the monitoring static spring 6, so that the glue liquid is evenly distributed in a short time, avoiding the glue liquid from gathering, and making the bonding more stable after curing. In addition, the wedge-shaped protrusion 47 can play a guiding role when inserting the monitoring movable spring 5 and the monitoring static spring 6, and after the insertion is completed, it plays a clamping role on the monitoring movable spring 5 and the monitoring static spring 6 to prevent the monitoring movable spring 5 or the monitoring static spring 6 from moving in the vertical direction Z.

[0067] like Fig.13 and Fig.17 As shown, in some embodiments, the monitoring dynamic spring 5 includes a first lead-out portion 51, which is inserted into the first glue dispensing port 43. The first lead-out portion 51 is provided with a first notch 511. The first notch 511 is located at the position of the first lead-out portion 51 in contact with the first partition 41 to make way for the flowing glue during glue dispensing. At the same time, it can also temporarily store the flowing glue to play a buffering role, so that the glue flows evenly and is distributed more evenly, thereby improving the stability of the bonding and avoiding loosening due to external force, thereby improving the reliability of monitoring the monitoring dynamic spring 5 and the monitoring static spring 6.

[0068] like Fig.12 and Fig.13 As shown, in some embodiments, the monitoring spring 5 further includes a first connecting portion 52 and a first spring portion 53, and the first lead-out portion 51 and the first spring portion 53 are connected to opposite sides of the first connecting portion 52; Fig.17 As shown, the first connecting portion 51 is inserted into the insertion space, the first lead-out portion 51 is inserted into the first dispensing port 43 and extends out of the insertion space from the first dispensing port 43 , and the first reed portion 53 extends out of the insertion space and extends toward the base 1 .

[0069] like Fig.16 and Fig.17As shown, the top end of the first connecting portion 52 of the monitoring dynamic spring 5 abuts against the bottom surface of the first partition 41. After glue dispensing, the top surface of the first connecting portion 52 can be bonded and fixed to the bottom surface of the first partition 41. Therefore, the first partition 41 not only plays a role of separation, but also plays a role of fixing the first connecting portion 52.

[0070] like Fig.15 As shown, the monitoring static spring 6 includes a second lead-out portion 61, which is inserted into the second glue dispensing port 44. The second lead-out portion 61 is provided with a second notch 611, and the second notch 611 is located at the contact portion between the second lead-out portion 61 and the first partition 41, so as to make way for the flowing fixed glue during glue dispensing, and also temporarily store the flowing glue to play a buffering role, so that the glue flows evenly and is more evenly distributed, thereby improving the stability of the bonding and avoiding loosening due to external force, thereby improving the reliability of monitoring the monitoring dynamic spring and the monitoring static spring.

[0071] like Fig.14 and Fig.15 As shown, the monitoring static spring 6 further includes a second connecting portion 62 and a second spring piece portion 63, and the second lead-out portion 61 and the second spring piece portion 63 are connected to opposite sides of the second connecting portion 62. Fig.18 As shown, the second connecting portion 62 is inserted into the insertion space, the second lead-out portion 61 is inserted into the second dispensing port 44 and extends out of the insertion space from the second dispensing port 44, and the second spring portion 62 extends out of the insertion space and extends toward the base 1.

[0072] In some embodiments, the first notch 511 and the second notch 611 may respectively include any one of an arc-shaped notch, a rectangular notch, a trapezoidal notch and a polygonal notch, which is not particularly limited here.

[0073] like Fig.18 As shown, the top end of the second connection part 62 of the monitoring static spring 6 abuts against the bottom surface of the first partition 41. After glue dispensing, the top surface of the second connection part 62 can be bonded and fixed to the bottom surface of the first partition 41. Therefore, the first partition 41 not only plays a role of separation, but also plays a role of fixing the second connection part 62.

[0074] like Fig.15 As shown, the monitoring static spring 6 further includes a reinforcing portion 64, which is located at the top of the second connecting portion 62 and is arranged opposite to the second lead-out portion 61. The reinforcing portion 64 protrudes from the top of the second connecting portion 62 in the vertical direction Z. Fig. 9 As shown, there are multiple second glue dispensing ports 44 , the reinforcing portion 64 is inserted into the second glue dispensing port 44 away from the second lead-out portion 61 , and the top of the reinforcing portion 64 is lower than the top of the second glue dispensing port 44 .

[0075] like Fig.18As shown, after the monitoring static spring 6 is inserted into the insertion space, the reinforcing portion 64 can be inserted into the second glue dispensing port 44, and the top of the reinforcing portion 64 is lower than the top of the second glue dispensing port 44 to temporarily store the glue during glue dispensing so that the glue can flow smoothly downward.

[0076] like Fig. 9 and Fig.10 As shown, in some embodiments, the insertion structure 4 may further include a second partition 42, which is disposed in the insertion space to divide the insertion space into a first insertion space S1 and a second insertion space S2. In some embodiments, the insertion space is surrounded by the inner peripheral wall of the insertion structure 4, the second partition 42 extends along the second horizontal direction Y in the insertion space, and both ends of the second partition 42 are connected to the side walls of the insertion space to divide the space into a first insertion space S1 and a second insertion space S2, the monitoring dynamic spring 5 is inserted in the first insertion space S1, and the monitoring static spring 6 is inserted in the second insertion space S2, thereby isolating the monitoring dynamic spring 5 from the monitoring static spring 6 to prevent the two from contacting each other.

[0077] like Fig. 9 As shown, the first partition 41 is located at the top of the first insertion space S1 and the second insertion space S2. In some embodiments, the first partition 41 and the top of the second partition 42 are cross-shaped, such as Fig.10 and Fig.11 As shown, the size of the first partition 41 in the vertical direction Z is smaller than that of the second partition 42, that is, the first partition 41 does not extend to the bottom of the insertion space in the vertical direction Z, so that the monitoring spring 5 and the monitoring spring 6 can be accommodated in the first insertion space S1 and the second insertion space S2. It can also be understood that the first partition 41 covers the top of the first insertion space S1 and the second insertion space S2. The first partition 41 is provided with a plurality of openings, and the opening corresponding to the first insertion space S1 can be called the first dispensing port 43, and the opening corresponding to the second insertion space S2 can be called the second dispensing port 44.

[0078] In some embodiments, Fig. 9 As shown, there can be multiple first dispensing ports 43, and the multiple first dispensing ports 43 correspond to the first insertion space S1 in the vertical direction Z, and the monitoring spring 5 extends from one of the first dispensing ports 43. There can be multiple second dispensing ports 44, and the multiple second dispensing ports 44 correspond to the second insertion space S2 in the vertical direction Z, and the monitoring static spring 6 extends from one of the second dispensing ports 44.

[0079] By setting a plurality of first dispensing ports 43 and a plurality of second dispensing ports 44, the dispensing position can be flexibly selected. For example, the dispensing port located in the middle can be selected, and the glue will flow from the middle to both sides, making the distribution of the glue more uniform, avoiding glue accumulation, and improving the stability of the bonding. Of course, other dispensing ports can also be selected for dispensing, or glue can be dispensed at each dispensing port, and no special limitation is made here.

[0080] In some embodiments, the number of the first dispensing port 43 and the second dispensing port 44 can be one, two, three, four or more respectively, and when there are multiple first dispensing ports 43 and multiple second dispensing ports 44 respectively, the sizes of the multiple first dispensing ports 43 can be different or the same, and the sizes of the multiple second dispensing ports 44 can be the same or different, and there is no special limitation here.

[0081] like Figure 8 As shown, the first dispensing port 43 extending from the monitoring movable spring 5 and the second dispensing port 44 extending from the monitoring static spring 6 are respectively located at the two ends of the diagonal of the insertion structure 4, so that the tops of the monitoring movable spring 5 and the monitoring static spring 6 are as far away as possible to avoid contact and misjudgment. Of course, you can also choose a dispensing port that is not located on the diagonal line, as long as the extended parts of the monitoring movable spring 5 and the monitoring static spring 6 do not contact, and there is no special limitation here.

[0082] like Fig.13 and Fig.15 As shown, the first spring leaf portion 53 of the monitoring movable spring 5 is provided with a monitoring movable contact 531, and the second spring leaf portion 63 of the monitoring static spring 6 is provided with a monitoring static contact 631. When the magnetic circuit assembly 2 drives the monitoring movable spring 5 to move, the monitoring movable contact 531 contacts the monitoring static contact 631.

[0083] In the utility model, a first glue dispensing port 43 and a second glue dispensing port 44 are provided on the plug-in structure 4 of the fixing frame 3, which can not only simplify the glue dispensing operation, but also facilitate the flow of glue and the uniformity of the distribution of glue, thereby improving the stability of the bonding of the monitoring movable spring 5 and the monitoring static spring 6, thereby further improving the stability of the monitoring of the magnetic holding relay by the monitoring movable spring 5 and the monitoring static spring 6, and at the same time can effectively avoid the pins of the monitoring static spring 6 and the monitoring movable spring 5 from being glued.
