[0035] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0038] At the same time, the meaning of "and / or" or "and / or" appearing in the full text includes three options. Taking "A and / or B" as an example, it includes option A, or option B, or a option in which both A and B are satisfied.

[0039] In addition, in the present utility model, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0040] Please combine Figures 1 to 9 As shown, the utility model proposes a relay 100, which includes a mounting shell 1 and a moving component. The mounting shell forms a mounting cavity 11. The cavity wall of the mounting cavity 11 is provided with at least one group of dividing ribs 12, and each group of dividing ribs 12 includes two dividing ribs 12 arranged at intervals; one end of the moving component is movably arranged in the mounting cavity 11, and one end of the moving component located in the mounting cavity 11 is provided with a bending protrusion 2121, the bending protrusion 2121 is arranged opposite to the cavity wall of the mounting cavity 11, and is gap-matched with the cavity wall of the mounting cavity 11, and the bending protrusion 2121 is located between the two dividing ribs 12.

[0041] In this embodiment, if Figures 1 to 3 As shown, a group of separation ribs 12 includes two separation ribs 12, and the two separation ribs 12 are protruding from the cavity wall of the installation cavity 11. The moving component extending into the installation cavity 11 is provided with a bending protrusion 2121, and the bending protrusion 2121 is arranged opposite to the cavity wall of the installation cavity 11, and the bending protrusion 2121 is located between the two separation ribs 12. When the moving component moves in the installation cavity 11 and tilts or rotates, the bending protrusion 2121 abuts and rubs against the cavity wall of the installation cavity 11 to limit the moving component from further tilting or rotating, so that the relay 100 is normally connected or disconnected. The setting of the bending protrusion 2121 avoids the contact or friction between other parts of the moving component and the cavity wall of the installation cavity 11, so as to reduce the friction coefficient between the moving component and the cavity wall of the installation cavity 11, reduce the amount of dust produced by friction in the installation cavity 11, reduce the content of pollutants in the installation cavity 11, ensure the cleanliness in the installation cavity 11, and ensure the reliability of the mechanical life and electrical life of the relay 100. The arrangement of the separation rib 12 and the bending protrusion 2121 plays a certain guiding role in the installation of the moving component. At the same time, the arrangement of the separation rib 12 divides the space of the installation cavity 11 into multiple areas, which can to a certain extent prevent the arc burning of the contacts on both sides from generating dust.

[0042] It is understandable that the mounting shell 1 is composed of a ceramic cover 13, a frame sheet 14, a yoke iron plate 15 and a metal shell 16. The ceramic cover 13 is enclosed to form a cavity with an opening. The frame sheet 14 surrounds the opening and is brazed with the ceramic cover 13. The yoke iron plate 15 covers the opening and is laser welded with the frame sheet 14. In this way, the mounting cavity 11 is enclosed. The metal shell 16 wraps the part of the moving component outside the mounting cavity 11 and is laser welded with the yoke iron plate 15 to form a closed space in the mounting cavity 11. An exhaust pipe connected to the mounting cavity 11 is also provided on the yoke iron plate 15. The air in the mounting cavity 11 can be exhausted through the exhaust pipe, and the mixed gas can be filled into the mounting cavity 11 to suppress the arc. Finally, the exhaust pipe is mechanically sealed. It is understandable that the partition rib 12 can be integrally formed with the ceramic cover 13.

[0043] In one embodiment of the present invention, Figure 2 and Figure 5 As shown, the bending protrusion 2121 includes two straight sections and one curved section. The two straight sections are arranged at both ends of the curved section and are smoothly connected to the curved section. The convex surface of the curved section is gap-matched with the cavity wall of the installation cavity 11.

[0044] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, two cavity walls opposite to each other of the installation cavity 11 are respectively provided with a group of partition ribs 12, and the two groups of partition ribs 12 are located on both sides of the moving component. The moving component is provided with a bending protrusion 2121 corresponding to each group of partition ribs 12; and / or, the partition ribs 12 are extended along the moving direction of the moving component.

[0045] In this embodiment, two groups of separation ribs 12 are arranged on two opposite cavity walls. The two groups of separation ribs 12 are located on both sides of the moving assembly to roughly divide the installation cavity 11 into three spaces in cooperation with the moving assembly. The contacts of the relay 100 are respectively located in the three spaces to reduce the possibility of arc generation. The separation ribs 12 are extended along the moving direction of the moving assembly to avoid affecting the movement of the moving assembly in the installation cavity 11. It can be understood that the two groups of separation ribs 12 are arranged perpendicular to the connecting line of the two moving contacts of the moving assembly, thereby separating the two moving contacts.

[0046] Optionally, the two groups of separation ribs 12 may be arranged opposite to each other or in a staggered manner, which is not specifically limited here.

[0047] In one embodiment of the present invention, Figure 2 and Figure 4As shown, the dynamic assembly includes a dynamic spring component 2 and a push rod component 5. The dynamic spring component 2 is movably arranged in the installation cavity 11. The outer wall of the dynamic spring component 2 is provided with a bending protrusion 2121. The installation shell 1 is provided with a through opening connected to the installation cavity 11. The push rod component 5 is movably arranged in the through opening and connected to the dynamic spring component 2; wherein the push rod component 5 drives the dynamic spring component 2 to move in the installation cavity 11 so that the bending protrusion moves along the cavity wall of the installation cavity 11.

[0048] In this embodiment, the push rod member 5 drives the movable spring member 2 to move in the installation cavity 11 to realize the conduction and disconnection of the relay 100. The outer wall of the movable spring member 2 is provided with a bending protrusion 2121 that cooperates with the cavity wall of the installation cavity 11. When the movable spring member 2 moves in the installation cavity 11, the bending protrusion 2121 moves along the cavity wall of the installation cavity 11 to avoid the movable spring member 2 from tilting or rotating significantly in the installation cavity 11, and at the same time avoid the rest of the movable spring member 2 from abutting and rubbing against the cavity wall of the installation cavity 11, thereby reducing the wear of the movable spring member 2 and ensuring the normal operation of the relay 100.

[0049] In one embodiment of the present invention, Figure 2 and Figure 4 As shown, the relay 100 also includes an auxiliary static terminal 3 and a lead-out terminal 4, and the auxiliary static terminal 3 and the lead-out terminal 4 at least partially extend into the installation cavity 11; the dynamic spring member 2 includes a fixing frame 21, a dynamic spring piece 22 and an auxiliary dynamic spring member 23, the fixing frame 21 encloses a cavity 214 and is provided with a bending protrusion 2121, the dynamic spring piece 22 is elastically connected to the fixing frame 21 and is located in the cavity 214, the auxiliary dynamic spring member 23 and the push rod member 5 are respectively connected to the two ends of the fixing frame 21; wherein the push rod member 5 drives the dynamic spring piece 22 to abut against or separate from the lead-out terminal 4, and the push rod member 5 drives the auxiliary dynamic spring member 23 to abut against or separate from the auxiliary static terminal 3.

[0050] In this embodiment, the auxiliary static terminal 3 and the lead-out terminal 4 at least partially extend into the installation cavity 11, and the outer wall of the fixing frame 21 is provided with a bent protrusion 2121 that matches the cavity wall of the installation cavity 11. When the push rod 5 drives the dynamic spring member 2 to move toward the auxiliary static terminal 3 and the lead-out terminal 4, the auxiliary static terminal 3 and the auxiliary dynamic spring member 23 are in contact with each other and conduction, and the dynamic spring piece 22 is in contact with the lead-out terminal 4 and conduction, and the dynamic spring piece 22 is elastically connected to the fixing frame 21, so that the dynamic spring piece 22 and the lead-out terminal 4 are in contact more closely, ensuring the reliability of the conduction of the relay 100. The auxiliary dynamic spring member 23 and the dynamic spring piece 22 are both connected to the fixing frame 21, so that the auxiliary dynamic spring member 23 and the dynamic spring piece 22 move synchronously, when the dynamic spring piece 22 is in contact with the lead-out terminal 4, the auxiliary dynamic spring member 23 is also in contact with the auxiliary static terminal 3, and when the dynamic spring piece 22 is separated from the lead-out terminal 4, the auxiliary dynamic spring member 23 is also separated from the auxiliary static terminal 3. The lead-out terminal 4 cooperates with the moving reed 22 to realize the on and off of the relay 100 , and the auxiliary moving spring 23 cooperates with the auxiliary static terminal 3 to monitor the actual working status of the lead-out terminal 4 and the moving reed 22 .

[0051] It can be understood that the auxiliary static terminal 3 and the lead-out terminal 4 each include two, the ceramic cover 13 is provided with a main contact mounting hole and an auxiliary contact mounting hole, the lead-out terminal 4 extends into the mounting cavity 11 through the main contact mounting hole, and the auxiliary static terminal 3 extends into the mounting cavity 11 through the auxiliary contact mounting hole. At the same time, a plurality of steps are also provided on the outer side of the ceramic cover 13, and the steps are arranged around the main contact mounting hole and the auxiliary contact mounting hole to facilitate the coating of the metallization layer.

[0052] In one embodiment of the present invention, Figure 4 As shown, the fixing frame 21 has a top wall 211 , a bottom wall 213 and two side walls 212 connected to each other. The top wall 211 , the bottom wall 213 and the two side walls 212 enclose a cavity 214 . The two side walls 212 are arranged opposite to each other and bent to form a bending protrusion 2121 .

[0053] In this embodiment, the fixing frame 21 is formed by a top wall 211, a side wall 212, a bottom wall 213 and another side wall 212 connected in sequence to enclose a cavity 214. The two side walls 212 are arranged opposite to each other, and the side walls 212 are arranged opposite to the cavity wall with the installation cavity 11, and the bending protrusions 2121 are arranged on the two side walls 212.

[0054] It can be understood that the side wall 212 has two straight sections and one curved section, and the two straight sections are respectively connected to the two ends of the curved section, and are used to connect with the top wall 211 and the bottom wall 213, so that the top wall 211 and the side wall 212, and the side wall 212 and the bottom wall 213 are arranged vertically. The curved section is smoothly connected to the two straight sections, and the connection between the curved section and the straight section is slightly bent to form a bending protrusion 2121. Optionally, the two straight sections and the curved section are integrally formed, and the bending protrusion 2121 has a certain elasticity, so that the moving component can rebound to the central position after rotation. The side wall 212 is provided with a through hole, and the two curved protrusions are located on both sides of the through hole. The provision of the through hole reduces the production materials of the fixing frame 21 and reduces the production cost.

[0055] In an embodiment of the present invention, each side wall 212 is provided with at least two bending protrusions 2121 ; and / or the bending protrusions 2121 are in a smooth transition.

[0056] In this embodiment, each side wall 212 is provided with at least two bending protrusions 2121, so that the two bending protrusions 2121 cooperate with the cavity wall of the installation cavity 11 at the same time to prevent the other parts except the bending protrusions 2121 from rubbing against the cavity wall of the installation cavity 11 when the moving component rotates. The bending protrusions 2121 are smoothly transitioned to reduce the friction coefficient between the bending protrusions 2121 and the cavity wall of the installation cavity 11, and minimize the dust particles generated by the friction between the bending protrusions 2121 and the cavity wall of the installation cavity 11.

[0057] In one embodiment of the present invention, Figure 2 , Figure 4 , Figure 8 and Fig. 9 As shown, the moving component also includes a first magnetic block 24 and a second magnetic block 25 arranged in the cavity 214. The first magnetic block 24 is riveted to the top wall 211, and the second magnetic block 25 is elastically connected to the bottom wall 213, and two bosses 252 are provided toward the first magnetic block 24. The two bosses 252 are opposite to each other and spaced apart. The moving spring leaf 22 is snap-connected to the second magnetic block 25 and is limited between the two bosses 252.

[0058] In this embodiment, the moving component also includes a first magnetic block 24 and a second magnetic block 25. When the moving reed 22 abuts against the lead-out terminal 4 and is connected, the boss 252 of the second magnetic block 25 abuts against the first magnetic block 24, and the first magnetic block 24 and the second magnetic block 25 form a magnetic circuit to generate an electromagnetic attraction. The electromagnetic attraction is used to resist the electric repulsion generated when the moving reed 22 abuts against the lead-out terminal 4 and is connected, thereby preventing the moving reed 22 from separating from the lead-out terminal 4, effectively suppressing the generation of an electric arc, and improving the short-circuit resistance and safety of the relay 100 during operation.

[0059] It can be understood that the first magnetic block 24 is provided with a mounting protrusion 241 on the side facing the top wall 211, and the top wall 211 is provided with a mounting through hole 2111 corresponding to the mounting protrusion 241. During assembly, the mounting protrusion 241 passes through the mounting through hole 2111 and is then extended and riveted to make the first magnetic block 24 and the top wall 211 riveted together. The second magnetic block 25 is provided with a limiting groove 251 on the side facing the moving spring piece 22, and the moving spring piece 22 is provided with a limiting protrusion 221 corresponding to the limiting groove 251. The limiting protrusion 221 is engaged in the limiting groove 251. At the same time, the moving spring piece 22 abuts against the two bosses 252 of the second magnetic block 25, thereby limiting the horizontal movement of the moving spring piece 22.

[0060] Optionally, a process groove 222 is further provided on a side of the movable spring piece 22 facing away from the limiting convex bump 221 to facilitate the production and molding of the limiting convex bump 221, and a process convex bump 243 is further provided on the first magnetic conductive block 24 to prevent the first magnetic conductive block 24 from laminating during the electroplating process, thereby reducing the defective rate of the electroplating process. The boss 252 of the second magnetic conductive block 25 also abuts against the straight section of the side wall 212, thereby guiding and limiting the movement of the movable spring piece 22 in the cavity 214.

[0061] In one embodiment of the present invention, Figure 2 , Figure 4 and Figure 7As shown, the auxiliary dynamic spring member 23 includes a mounting platform 231, an auxiliary dynamic spring piece 232 and a rivet 233. The auxiliary dynamic spring piece 232 is connected to the mounting platform 231 and is provided with an auxiliary dynamic contact that cooperates with the auxiliary static terminal 3.

[0062] In this embodiment, the auxiliary dynamic spring member 23 is composed of a mounting platform 231, an auxiliary dynamic spring piece 232 and a rivet 233. The auxiliary dynamic contact is symmetrically designed. The auxiliary dynamic spring piece 232 is connected to the side of the mounting platform 231 facing away from the fixed frame 21. The rivet 233 is penetrated through the rivet hole 2311 of the mounting platform 231, the avoidance groove 2112 of the top wall 211 and the mounting hole 244 of the first magnetic conductive block 24, and connects the mounting platform 231, the bottom wall 213 and the first magnetic conductive block 24. The mounting platform 231 is provided with a ring platform 2312 corresponding to the avoidance groove 2112, and the ring platform 2312 is limited to the avoidance groove 2112 to realize the positioning, installation and limitation of the mounting platform 231 and the top wall 211.

[0063] It can be understood that the mounting platform 231 is made of plastic material, and the mounting platform 231 is provided with a through slot for the auxiliary moving spring 232 to pass through, and a positioning hole 2314 is provided on the slot wall of the through slot, and the positioning hole 2314 includes a plurality of holes to realize the positioning and limiting of the moving spring 22, so as to facilitate the rubber-coated connection between the moving spring 22 and the mounting platform 231. The mounting platform 231 is also provided with an insulating boss 2313, and the insulating boss 2313 is arranged around the bottom wall 213 to increase the creepage distance between the moving spring 22 and the auxiliary moving contact. The first magnetic conductive block 24 is also provided with a U-shaped groove 242 on the side facing away from the bottom wall 213, and the U-shaped groove 242 is arranged around the mounting hole 244 to avoid the rivet head of the rivet 233, so as to ensure that the mating surface of the first magnetic conductive block 24 and the moving spring 22 is a plane, so as to avoid the first magnetic conductive block 24 and the second magnetic conductive block 25 from being unable to conduct magnetically.

[0064] Optionally, the auxiliary moving spring piece 232 can be bent at a portion close to the auxiliary moving contact to give the auxiliary moving contact a certain elasticity, so that it can be more tightly abutted against the auxiliary static terminal 3. The auxiliary moving spring piece 232 can be riveted or welded to the auxiliary contact point at the position of the auxiliary moving contact as required to improve the electrical life performance of the auxiliary moving contact.

The push rod 51 is passed through the through hole 2132 and is connected to the mounting seat 52. The spring member 53 is connected to a side of the mounting seat 52 facing away from the push rod 51 and is connected to the second magnetic conductive block 25.

[0066] In this embodiment, when the mounting seat 52 and the bottom wall 213 are molded by rubber coating, plastic is filled in the reinforcement hole 2131 of the bottom wall 213 to improve the connection strength between the fixing frame 21 and the mounting seat 52. The mounting seat 52 is connected to a spring member 53, one end of which is inserted into the mounting groove provided on the mounting seat 52, and the second magnetic conductive block 25 is provided with a limiting protrusion 253 corresponding to the spring member 53, and the other end of the spring member 53 is sleeved on the limiting protrusion 253, so as to realize the elastic connection between the movable spring 22 and the second magnetic conductive block 25 and the bottom wall 213. The bottom wall 213 is also provided with a through hole 2132 for the push rod 51 to pass through, and one end of the push rod 51 is passed through the through hole 2132 and connected to the mounting seat 52. It can be understood that the mounting seat 52 is made of plastic. The push rod 51 and the mounting platform 231 can also be connected by rubber coating, which is not specifically limited here.

[0067] It can be understood that the part of the push rod 51 outside the installation cavity 11 is connected to the moving iron core, and the relay 100 pushes the push rod member 5 to move in the installation cavity 11 through the moving iron core. The moving iron core is connected to one end of the push rod 51 away from the mounting seat 52 to ensure the travel of the push rod member 5 and the moving spring member 2 in the installation cavity 11. A reaction spring member can be arranged between the moving iron core and the mounting shell 1. The moving iron core is used to push the push rod member 5 to move. When the moving iron core pushes the push rod member 5 to drive the moving spring member 2 to move toward the lead-out terminal 4, the reaction spring member is compressed to buffer and stop the movement of the moving iron core.

[0068] In actual implementation, the moving iron core and the push rod 5 can be connected by threaded cooperation, and the moving iron core is provided with a coil. The movement of the moving iron core can be controlled by turning the coil on and off to connect or disconnect the moving spring piece 22 and the lead-out terminal 4, so as to achieve the purpose of the relay 100 controlling the linkage or disconnection of the large current. During the disconnection process of the relay 100, the push rod 5 is no longer subjected to the force given by the moving iron core. Under the elastic force of the spring member 53 and the reaction spring member, the moving iron core and the push rod 5 drive the moving spring member 2 to move downward rapidly, and drive the moving spring piece 22 to move downward, so that the moving spring piece 22 is separated from the lead-out terminal 4, the main circuit is disconnected, and the current no longer flows in the moving spring piece 22, and the first magnetic conductive block 24 and the second magnetic conductive block 25 lose their magnetic attraction.

[0069] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
