DETAILED DESCRIPTION

[0045] 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 this application 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.

[0046] like Figures 1 to 5 As shown, an embodiment of the present application provides a relay. The relay comprises: a housing 100, a main body component 200 and a connecting frame 300, wherein the housing 100 is provided with an exposure hole 111; the main body component 200 is placed in the housing 100, and there is a gap between the main body component 200 and the housing 100; the main body component 200 comprises an insulating cover 220, a static contact 210, a coil 230 and a coil frame 240, the static contact 210 is fixed relative to the insulating cover 220, and part of the static contact 210 is located outside the insulating cover 220 and exposed through the exposure hole 111; the coil frame 240 is placed on the side of the insulating cover 220 away from the exposure hole 111, and the coil 230 is installed on the coil frame 240; the connecting frame 300 is placed in the housing 100 and is located in the gap; the connecting frame 300 comprises a frame 310 and two conductive sheets 320 integrally formed with the frame 310; it can be understood that the frame 310 is made of insulating material to ensure that the two conductive sheets 320 are effectively isolated.

[0047] Each conductive sheet 320 has a connection end and a lead-out end exposed from the frame 310 . The connection end is connected to a free end of the coil 230 , and the lead-out end extends from a side of the housing 100 where the exposure hole 111 is provided to the outside of the housing 100 .

[0048] In the relay provided in the embodiment of the present application, the static contact 210 in the main assembly 200 is fixed relative to the insulating cover 220, and part of the static contact 210 extends out of the insulating cover 220 and is exposed by the exposure hole 111 of the housing 100, that is, the static contact 210 is led out from the exposure hole 111. It is worth noting that the part of the static contact 210 exposed through the exposure hole 111 can be understood as the lead-out end of the static contact 210.

[0049] Please continue to refer to Figures 1 to 5 In the structure shown, the relay provided in the embodiment of the present application leads the coil 230 from one side of the static contact 210 of the relay through the connecting frame 300. The connecting frame 300 effectively utilizes the gap between the main body component 200 and the inner wall of the housing 100, and reasonably utilizes the internal space of the relay, which is conducive to the miniaturization of the relay. At the same time, since the relay itself has a concave-convex design on the side where the static contact 210 is led out, when the lead-out end of the conductive sheet 320 is set on this side, the space of the relay on this side can be fully utilized, and there is no need to separately set the external lead-out structure of the coil 230, which occupies additional volume, and can further facilitate the miniaturization of the relay.

[0050] It is worth noting that, since the frame body 310 in the connecting frame 300 effectively wraps the conductive sheet 320 except for the ends on both sides, the connecting frame 300 can ensure the conductive stability and prevent the conductive sheet 320 from contacting with other structures in the relay and causing a short circuit. In addition, the frame body 310 in the connecting frame 300 can provide effective support for the conductive sheet 320, making it easier for the conductive sheet 320 to connect with other structures and preventing the conductive sheet 320 from being insufficiently supported and deformed.

[0051] In one embodiment, please continue to refer to Figure 1 In the structure shown, the housing 100 includes a first housing 110 and a second housing 120, and the second housing 120 is fixed relative to the first housing 110 to form a chamber for accommodating other components in the relay. Figure 1 As shown, the first housing 110 is shown as a cover structure, and the second housing 120 is shown as a cover structure. Of course, the structures of the first housing 110 and the second housing 120 are not limited to Figure 1 As shown, the first shell 110 and the second shell 120 can also be both cover structures, which can be specifically configured according to requirements and will not be described in detail here.

[0052] In addition, the fixing form between the second shell 120 and the first shell 110 can be selected according to the needs. For example, one or more of the following methods can be selected: snap connection, interference connection or gluing.

[0053] When the relay provided in the embodiment of the present application is set, the insulating cover 220 can be a ceramic cover, and the insulating cover 220 is used to cover the main contact. Specifically, a moving contact piece and an elastic member are arranged in the insulating cover 220, and the moving contact piece can contact or separate the stationary contact 210, and the main contact of the relay is formed between the two; the elastic member is placed on the side of the moving contact piece facing away from the stationary contact 210, and is used to provide pressure for the contact between the moving contact piece and the stationary contact 210.

[0054] In one embodiment, Figure 2 and Figure 3 As shown, the main assembly 200 further includes a coil lead-out sheet 250 fixed to the coil frame 240, and each conductive sheet 320 is connected to a free end of the coil 230 through the coil lead-out sheet 250. The coil 230 is connected to the conductive sheet 320 through the coil lead-out sheet 250 to improve the stability of the connection relationship between the coil 230 and the conductive sheet 320.

[0055] It is worth noting that the shape of the coil lead-out piece 250 can be set according to demand to reasonably utilize the internal space of the relay, improve the space utilization rate inside the relay, and facilitate the miniaturization of the relay.

[0056] In a specific embodiment, the coil lead-out piece 250 and the coil frame 240 are an integrally formed structure. Exemplarily, the integrally formed coil frame 240 and the coil lead-out piece 250 can be formed by injection molding to reduce the difficulty of manufacturing and improve the manufacturing efficiency.

[0057] like Figure 2 and Figure 3 As shown, one end of the coil lead-out piece 250 extends out of the coil frame 240 and is wound and connected by the coil 230 , and the other end is connected to the connection end of the conductive piece 320 .

[0058] It should be noted that the integrally formed structure of the coil lead-out piece 250 and the coil frame 240 can improve the stability of the coil lead-out piece 250 relative to the coil frame 240, thereby improving the stability of the connection relationship between the coil 230 and the conductive sheet 320, and improving the structural performance of the relay.

[0059] In one embodiment, please combine Figures 1 to 6 refer to Figure 7 and Figure 8In the structure shown, the conductive sheet 320 has a first portion 321 and a second portion 322, wherein one end of the first portion 321 away from the second portion 322 forms a connection end, and one end of the second portion 322 away from the first portion 321 forms a lead-out end, and the second portion 322 is bent relative to the first portion 321 to reasonably utilize the internal space of the relay.

[0060] In a specific embodiment, a large surface of the first portion 321 is parallel to a side surface of the housing 100 adjacent thereto.

[0061] It can be understood that the gap between the main body component 200 and the inner wall of the shell 100 is smaller on the side away from the static contact 210. By setting the large surface of the first part 321 to be parallel to the side surface of the shell 100 close to it, the space inside the relay can be reasonably utilized, the utilization rate of the space inside the relay is improved, and the miniaturization of the relay is further facilitated.

[0062] It is worth noting that the bending state of the second portion 322 relative to the first portion 321 can be set according to customer needs. As an example, in this embodiment, the large surface of the second portion 322 is perpendicular to the side surface of the housing 100 close to it, so as to effectively utilize the larger space at the top of the relay, and facilitate the connection (e.g., plugging) operation between the conductive sheet 320 and the external structure.

[0063] If it is stipulated that the static contact 210 is led out from the top of the insulating cover 220, the connecting frame 300 is mainly placed in the gap between the insulating cover 220 and the inner wall of the housing 100. The gap between the insulating cover 220 and the inner wall of the housing 100 is small, and the gap between the static contact 210 and the inner wall of the housing 100 is large. Therefore, when the first part 321 and the second part 322 are specifically arranged, the second part 322 can be arranged at a position where the conductive sheet 320 exceeds the top of the insulating cover 220, so as to reasonably utilize the space inside the relay.

[0064] Of course, other structures may be arranged on the outside of the insulating cover 220 , and the gap for placing the connecting frame 300 may be formed by the other structures and the side wall of the housing 100 .

[0065] In one embodiment, please continue to refer to Figure 7 and Figure 8 In the structure shown, the connection end is a circular area 3211 (schematically separated by a dotted line), and the circular area 3211 is provided with a through hole 3212. It is worth noting that the circular area 3211 is exposed on both sides of the frame 310 to facilitate the connection operation between the coil lead-out sheet 250 and the conductive sheet 320. It can be understood that the area of ​​the circular area 3211 is relatively large, which can ensure the connection area between the coil lead-out sheet 250 and the conductive sheet 320.

[0066] Of course, the shape of the connection end is not limited to a circle, and other settings can be made according to needs, which will not be described in detail here.

[0067] Please combine Figure 7 and Figure 8 refer to Figure 2 and Figure 3 In the structure shown, the coil lead-out sheet 250 includes a columnar portion 251, which extends from the coil frame 240 and is inserted into the through hole 3212 to connect the conductive sheet 320, so as to reduce the difficulty of assembly. When connecting the conductive sheet 320 and the coil lead-out sheet 250, the columnar portion 251 extending into the through hole 3212 and the circular area of ​​the connection end can be welded to improve the reliability of the connection between the conductive sheet 320 and the coil lead-out sheet 250, and ensure that the low-voltage signal is effectively transmitted from the conductive sheet 320 to the outside of the relay.

[0068] like Figure 2 and Figure 3 As shown, the coil lead-out piece 250 further includes another part 252 , which is used to be fixed relative to the coil frame 240 and is wound by the coil 230 .

[0069] In one embodiment, the frame 310 is detachably connected to the housing 100. The detachable connection facilitates assembly and disassembly of the frame 310 and the housing 100, which can reduce assembly and disassembly difficulty and improve efficiency.

[0070] In a specific embodiment, please combine Figure 7 and Figure 8 refer to Fig.10 In the structure shown, the frame 310 is provided with an extension groove 311 extending along the first direction, and the extension groove 311 is provided with an opening on the side facing the exposure hole 111 set in the shell 100, and the first direction is parallel to the lead-out direction of the static contact 210 from the shell 100; the shell 100 is provided with a protrusion 112 extending along the first direction, and the protrusion 112 is placed in the extension groove 311 from the opening.

[0071] Take the case 100 including the first shell 110 and the second shell 120, and the convex portion 112 is provided on the first shell 110 as an example. When assembling the relay provided in the embodiment of the present application, the main assembly 200 can be placed in the second shell 120 first, and then the convex portion 112 on the surface of the first shell 110 is inserted from the opening into the extension groove 311 of the frame 310. When the first shell 110 is fixed relative to the second shell 120, the relative position of the frame 310 is locked by the first shell 110.

[0072] It should be noted that, in this embodiment, the connection structure between the housing 100 and the frame 310 is simple, which can reduce the difficulty of assembly. At the same time, the convex portion 112 of the housing 100 can effectively limit the relative position of the connecting frame 300 in the relay by cooperating with the extension groove 311 of the frame 310, thereby preventing the connecting frame 300 from shaking inside the housing 100 and improving the stability of the connection relationship between the conductive sheet 320 and the coil lead sheet 250.

[0073] It is worth noting that if the length of the protrusion 112 is too long, it will make the parts difficult to process and easy to break, but it will not affect the assembly stability; if the length of the protrusion 112 is too short, it will lead to the inability to achieve effective guidance, and thus it will be impossible to ensure the effective guidance and insertion of the coil lead-out piece 250 and the signal lead-out piece 260, which will affect the assembly stability.

[0074] In addition, there are many possible shapes of the protrusion 112. To facilitate assembly and ensure stability of the connection frame 300 and the housing 100 after assembly, the cross section of the protrusion 112 is preferably cross-shaped in a plane perpendicular to the first direction.

[0075] In one embodiment, a guiding slope is provided on one side of the protrusion 112 facing the bottom of the extension groove 311 to facilitate the assembly operation of the connecting frame 300 and the housing 100, thereby reducing the difficulty of assembly and improving the assembly efficiency.

[0076] In one embodiment, the coil frame 240 is snap-fitted to the frame 310. It is understandable that the snap-fitting connection between the coil frame 240 and the frame 310 can cooperate with the detachable connection between the housing 100 and the frame 310 to further improve the stability of the connecting frame 300 after assembly.

[0077] Of course, the coil frame 240 and the frame body 310 may also be connected in other detachable ways besides the snap connection, which will not be described in detail.

[0078] In a specific embodiment, the coil frame 240 is connected to the frame body 310 via a snap-fit ​​structure disposed in the gap, the snap-fit ​​structure includes a protrusion and a groove, the groove and the protrusion are adapted to each other, and one of the groove and the protrusion 1 is disposed on the coil frame 240 , and the other is disposed on the frame body 310 .

[0079] For example, please combine Figure 2 and Figure 3 refer to Figure 7 and Figure 8, the protrusion 241 is provided on the coil frame 240, and the groove 312 is provided on the frame body 310. When assembling the coil frame 240 in this embodiment, the frame body 310 of the connecting frame 300 is firstly clamped with the coil frame 240. After that, the main assembly 200 can be placed in the second shell 120, and then the protrusion 112 on the surface of the first shell 110 is removed from the opening into the extension groove 311 of the frame body 310. After the first shell 110 is fixed relative to the second shell 120, the relative position of the frame body 310 is locked by the first shell 110.

[0080] In one embodiment, please continue to refer to Figure 7 and Figure 8 In the structure shown, two conductive sheets 320 are spaced apart in the frame 310, and the frame 310 is provided with a retaining wall 313 structure between two adjacent conductive sheets 320. The retaining wall 313 structure can increase the creepage distance between the two conductive sheets 320 to improve the stability of the connection frame 300 in transmitting low-voltage signals.

[0081] It is worth noting that, in this embodiment, the retaining wall 313 structure forms part of the side wall of the extension groove 311, so as to reasonably arrange the support structure, improve the integration of the support, and reduce the difficulty of assembly and the manufacturing cost.

[0082] In one embodiment, please continue to refer to Figure 7 and Figure 8 In the structure shown, the frame 310 is provided with a hollow structure 314 at a portion located between two conductive sheets 320 , so as to reduce the weight of the frame 310 and facilitate the preparation of the connecting frame 300 .

[0083] In one embodiment, please continue to refer to Figure 1 and Figure 4 As shown in the structure, the relay provided in the embodiment of the present application also includes a signal lead-out sheet 260, one end of which is connected to the portion of the static contact 210 exposed from the exposure hole 111, and the other end of the signal lead-out sheet 260 forms a lead pin. The signal lead-out sheet 260 is used to transmit the high-voltage signal in the static contact 210 connected thereto to the external structure of the relay, so as to realize the sampling of the strong electric signal (i.e., the electric signal passing through the moving and static contacts, which is also the electric signal provided to the load), and has the characteristics of simple structure and easy operation. Exemplarily, one end of the signal lead-out sheet 260 is connected to the static contact 210, and the other end is connected to the connector or PCB (Printed Circuit Board) and other structures of the client.

[0084] Please continue to refer to Figure 1 and Figure 4In the illustrated mechanism, in one embodiment, the lead pins and the lead ends of the conductive sheet 320 are arranged in sequence and spaced apart. The lead pins of the signal lead sheet 260 and the lead ends of the conductive sheet 320 are centrally arranged on the surface of the housing 100 to facilitate the connection operation between the external device and the relay.

[0085] In a specific configuration, the lead pins of the signal lead sheet 260 and the lead ends of the conductive sheet 320 may form a shape similar to a quick-plug lead sheet to simplify the structure and reduce the difficulty of connection.

[0086] In one embodiment, please continue to refer to Figure 1 , Figure 4 and Fig.10 In the structure shown, the housing 100 is provided with a shielding structure 113 between the lead pin of the signal lead sheet 260 and the lead end of the conductive sheet 320 to effectively isolate the high voltage signal from the low voltage signal.

[0087] In a specific embodiment, along the direction in which the static contact 210 is led out of the housing 100 , the shielding structure 113 is higher than the lead-out pin and the lead-out end, so as to enhance the shielding effect of the shielding structure 113 .

[0088] In one embodiment, please continue to refer to Figure 2 and Figure 3 As shown in the structure, the relay provided in the embodiment of the present application also includes a yoke assembly 270, and at least a portion of the coil frame 240 is placed inside the yoke assembly 270 to form a complete magnetic circuit around the coil 230; the yoke assembly 270 has a notch, and the connecting frame 300 and the notch are located on the same side of the coil 230.

[0089] It should be noted that the above-mentioned gap can avoid the coil 230. This structural setting can facilitate the connection of the coil 230 to the connecting frame 300, reasonably utilize the space inside the relay, improve the utilization rate of the space inside the relay, and further facilitate the miniaturization of the relay.

[0090] As an example, the yoke assembly includes a U-shaped yoke and a yoke plate, which is placed at the U-shaped opening position of the U-shaped yoke and connects the U-shaped yoke to form a complete magnetic circuit around the coil 230.

[0091] It should be noted that the notch is provided on the U-shaped yoke, and the notch is used to make way for the connecting frame 300 .

[0092] In one embodiment, an arc extinguishing unit is disposed on the outer side of the insulating cover 220 , and the arc extinguishing unit is used to extinguish the arc generated between the main contacts in the insulating cover 220 .

[0093] As an example, the arc extinguishing unit includes two arc extinguishing magnets. The arc extinguishing magnets may be permanent magnets, and each arc extinguishing magnet may be substantially in the shape of a rectangular parallelepiped. The two arc extinguishing magnets are respectively disposed on both sides of the insulating cover 220 and are disposed opposite to each other along the length direction of the moving contact piece.

[0094] It should be noted that by providing two arc-extinguishing magnets arranged opposite to each other, a magnetic field can be formed around the stationary contact 210 and the moving contact piece. Therefore, the arc generated between the stationary contact 210 and the moving contact piece will be elongated in a direction away from each other by the action of the magnetic field, thereby achieving arc extinguishing.

[0095] In one embodiment, please continue to refer to Figure 2 and Figure 3 As shown in the structure, the relay provided in the embodiment of the present application also includes two yoke clamps 280, which are arranged around the insulating cover 220 and have a gap on the side close to each other, and the connecting frame 300 is at least located between the portion corresponding to the gap of the insulating cover 220 and the outer casing 100, so as to reasonably utilize the space inside the relay and improve the space utilization rate inside the relay.

[0096] The two yoke iron clips 280 mentioned above belong to the arc extinguishing unit, and the two yoke iron clips 280 are arranged corresponding to the positions of the two arc extinguishing magnetic steels. In addition, the two yoke iron clips 280 surround the arc extinguishing magnetic steel to prevent the magnetic field generated by the arc extinguishing magnetic steel from spreading outward and affecting the arc extinguishing effect. The yoke iron clips 280 are made of soft magnetic material. The soft magnetic material may include but is not limited to iron, cobalt, nickel, and alloys thereof.
