Description

Technical Field

[0001] The utility model relates to a relay, in particular to a moving reed structure for a clapper relay. Background Art

[0002] The clapper relay has technical characteristics such as simple structure, compact structure, small volume, and low power, and is widely used in working condition electrical equipment such as communication equipment, automobiles, and household appliances with a compact and narrow layout space. As Figure 1 shown, the small clapper relay has:

[0003] A bobbin 2' with an I-shaped structure, that is, the bobbin 2' has a winding cylinder, a contact side baffle extending radially at one end of the winding cylinder, and a pin side baffle extending radially at the other end of the winding cylinder;

[0004] An iron core mounted in the winding cylinder of the bobbin 2' with its head end at the contact side baffle;

[0005] A coil arranged on the winding cylinder of the bobbin 2', and the coil pins are mounted on the pin side baffle;

[0006] A yoke mounted on the bobbin 2' and beside the coil, and the knife edge position for supporting the armature is at the contact side baffle;

[0007] An armature assembled in a flip-up structure on the knife edge of the yoke, outside the contact side baffle, and capable of covering the head end of the iron core. Usually, the armature is formed into a flip-up assembly through the moving reed of a moving reed assembly 1'.

[0008] The moving reed of the moving reed assembly 1' is assembled on the armature. The contact part of the moving reed extends outward from the front end of the armature (with the yoke as the rear end). The moving contact connected to the moving reed is in the contact matching area outside the contact side baffle. The moving reed pin connected to the moving reed is mounted on the pin side baffle along the assembly position of the yoke. There is a contact elastic deformation part for elastic deformation of the contact part between the contact part for arranging the moving contact and the body.

[0009] A static reed assembly 3' is assembled on the bobbin 2'. The static contact 1 connected to the static reed is in the contact matching area outside the contact side baffle and is outside the moving contact, and the two form a normally closed matching relationship; the static reed pin 1 connected to the static reed is mounted on the pin side baffle;

[0010] A static reed assembly 4' is assembled on the bobbin 2'. The static contact 2 connected to the static reed is in the contact matching area outside the contact side baffle and is inside the moving contact, and the two form a normally open matching relationship.

[0011] The small clapper relay with the above structure consists of a magnetic circuit part composed of a coil, an iron core, a yoke and an armature assembled on a coil bobbin, a contact part composed of a moving reed assembly 1' and a static reed assembly two 4' assembled on the coil bobbin, and a limiting structure for restricting and positioning the outward turning of the moving reed assembly 1' constituted by the static reed assembly one 3'.

[0012] The operation process of the above small clapper relay is generally as follows:

[0013] When the exciting current flowing through the coil rises to a certain set value, the electromagnetic suction torque will overcome the reaction torque of the moving reed of the moving reed assembly, causing the armature to generate a clapping swing and internal rotation at the edge of the yoke. The moving contact of the moving reed assembly will then be attracted to the static contact two of the static reed assembly two within the contact matching area outside the contact side baffle to conduct the current path between the moving reed assembly and the static reed assembly two.

[0014] When the exciting current flowing through the coil drops to a certain set value, the reaction torque of the moving reed of the moving reed assembly is greater than the electromagnetic suction torque. The armature generates a swinging and external rotation at the edge of the yoke. The moving contact of the moving reed assembly will then be separated from the static contact two of the static reed assembly two within the contact matching area outside the contact side baffle to cut off the current path between the moving reed assembly and the static reed assembly two. The moving reed assembly with the swinging and external rotation is blocked and restricted by the static reed assembly one.

[0015] It can be seen from this that the moving reed of the relay with the above structure needs to repeatedly perform elastic switching between the static contact two and the static contact one in the contact matching area as the armature rotates inward and outward. This requires the contact elastic deformation part between the contact part and the body of the moving reed to have good elastic deformation ability. To achieve this technical purpose, the conventional method in the industry is to form a "necking" structure for the contact elastic deformation part of the moving reed and make the structure of the contact part as small as possible, such as Figure 1 shown.

[0016] However, for the moving reed structure as Figure 1 shown, although it has good elastic deformation performance, its "necking" structure has poor rigidity and is prone to deformation and even fracture during long-term repeated service, resulting in failure. In addition, its elastic deformation amount is limited by the overall structure of the contact elastic deformation part and is relatively limited, which is not conducive to forming a large elastic deformation amount during service. On the one hand, it cannot reliably form an over-travel action and is prone to failure to form reliable attraction and disconnection control due to structural deformation and / or elastic force fading in the middle and late stages of service; on the other hand, it cannot meet the forming technical requirements of the large working contact gap for the clapper relay. Utility Model Content

[0017] The technical object of the present utility model is: aiming at the particularity of the above-mentioned small clapper relay and the deficiencies of the existing moving reed technology, to provide a moving reed for a clapper relay that has both good elastic deformation performance and high structural rigidity.

[0018] The technical object of the present utility model is achieved through the following technical solutions. A moving reed for a clapper relay, the moving reed has an integrally formed armature connection part, a contact elastic deformation part, and a contact part;

[0019] The moving reed is connected to the armature of the clapper relay through the armature connection part and follows the movement of the armature;

[0020] The contact part under the action of the contact elastic deformation part extends forward at the front end of the armature and is located within the contact matching area of the clapper relay;

[0021] In the contact elastic deformation part of the moving reed, a through-hole structure elastic deformation groove one is provided in the central area.

[0022] The above technical measures aim at the particularity of the above-mentioned small clapper relay. A through-hole structure elastic deformation groove is provided on the contact elastic deformation part of the moving reed, so that the main body structures of the two sides of the contact elastic deformation part under the action of the elastic deformation groove are bifurcated and supported between the armature connection part and the contact part, reducing the structural stress of the elastic deformation. In this way, it can not only form good elastic deformation performance, effectively meet the technical requirements of durability, over-travel and large working contact gap during service, but also enable the contact elastic deformation part to be formed between the armature connection part and the contact part with a relatively large structural size, having good structural rigidity, not easily occurring deformation and fracture failure phenomena during service, and having good durability.

[0023] As one of the preferred technical solutions, the transverse width dimensions of the contact elastic deformation part of the moving reed are respectively smaller than those of the armature connection part and the contact part, and the two side edges of the transverse width of the contact elastic deformation part form a transverse inward contraction between the armature connection part and the contact part. This technical measure relatively "neckifies" the contact elastic deformation part of the moving reed on the basis of having an elastic deformation groove, further enhancing its elastic deformation performance, which is beneficial to reliably realizing the design and forming of a clapper relay with over-travel action and large working contact gap.

[0024] Furthermore, the top view outer contour of the contact elastic deformation part of the moving reed is in the shape of an isosceles trapezoid, and the large end of the isosceles trapezoid-shaped contact elastic deformation part is integrally connected to the armature connection part, and the small end is integrally connected to the contact part;

[0025] Correspondingly, the elastic deformation groove 1 opened in the central region of the contact elastic deformation part is of an isosceles trapezoid structure, and the orientation of the isosceles trapezoid structure elastic deformation groove 1 matches the isosceles trapezoid-shaped contact elastic deformation part.

[0026] The above technical measures form the contact elastic deformation part with a gradually changing structure in the shape of an isosceles trapezoid, so that the structural rigidity at the transition between the contact elastic deformation part as the elastic deformation root and the armature connection part is much greater than the structural rigidity between the contact elastic deformation part and the contact part. As a result, the contact elastic deformation part is formed with high structural rigidity on the relatively fixed armature connection part, and at the same time, a large elastic deformation amount is achieved under the cooperation of the elastic deformation groove and the gradually changing structure.

[0027] Alternatively, as an alternative solution, the top view outer contour of the contact elastic deformation part of the moving reed is rectangular;

[0028] Correspondingly, the elastic deformation groove 1 opened in the central region of the contact elastic deformation part is of a rectangular structure.

[0029] The above technical measures, as an alternative to the isosceles trapezoid-shaped contact elastic deformation part, have a certain high structural rigidity and large elastic deformation, but are inferior to the isosceles trapezoid-shaped contact elastic deformation part and are better than the traditional non-hollow "necking-down" structure.

[0030] As one of the preferred technical solutions, in the connection and cooperation structure between the moving reed and the armature, the front end of the armature is in the middle or the area before the middle of the contact elastic deformation part in an arc contour structure. Under the premise of meeting the technical requirements of the elastic deformation amount, the connected armature provides a supporting support for the transition between the contact elastic deformation part as the elastic deformation root and the armature connection part, so as to reduce the elastic fatigue of the transition between the contact elastic deformation part and the armature connection part during service and delay the long-term maintenance of structural rigidity.

[0031] As one of the preferred technical solutions, the moving reed also has an integrally formed yoke connection part and an attracting elastic deformation part;

[0032] The attracting elastic deformation part is formed in a bent structure between the yoke connection part and the armature connection part, and the attracting elastic deformation part is provided with an elastic deformation groove 2 in the central region for the articulated part of the flipping movement of the armature to be exposed at the moving reed;

[0033] The yoke connection part is used for fixedly connecting with the yoke of the clapper relay.

[0034] For the moving reed of the above technical measures, the armature is reliably connected to the yoke blade in a flippable structure, so that the flipping attraction force of the armature can be achieved with a small power, and basically no adjustment of the attraction power of the relay product is required.

[0035] Furthermore, at both edges of the yoke connecting portion in the transverse width direction, there are elastic buckles formed by inward folding respectively, and the cooperation distance between the two elastic buckles matches the transverse width dimension of the corresponding part of the yoke;

[0036] At the front side of the elastic buckle, there is an inwardly protruding barb, and the cooperation distance from the outer extension end of the barb to the inner wall of the yoke connecting portion matches the thickness dimension of the corresponding part of the yoke, and the cooperation distance between the outer extension ends of the barbs of the two elastic buckles is less than the transverse width dimension of the corresponding part of the yoke;

[0037] When the yoke connecting portion is combined and connected with the yoke, the elastic buckles on both sides of the yoke connecting portion hold the yoke in the transverse width direction, and the outer extension ends of the barbs of the elastic buckles on each side abut against the inner wall of the yoke.

[0038] The moving reed of the above technical measures reliably supplements the riveting relationship between the yoke connecting portion and the yoke with the elastic buckles on both sides of the yoke connecting portion, enabling the moving reed to form a stable fitting connection with the yoke, so as to ensure the reliability of the flip movement of the armature on the yoke.

[0039] As one of the preferred technical solutions, when the moving reed is assembled on the coil holder of the clapper relay, it is restricted and positioned by the limit buckle integrally formed on the contact side baffle of the coil holder, and the contact elastic deformation portion of the moving reed and the contact portion in front of the contact elastic deformation portion avoid the limit buckle. Based on the structural particularity of the clapper relay, this technical measure restricts and positions the moving reed with the limit buckle integrally formed on the contact side baffle of the coil holder, without the need to form the static reed assembly or positioning piece structure for the outward turning movement restriction and positioning on the outside of the original moving reed assembly. This is beneficial for leaving the arrangement position of the static reed assembly or positioning piece outside the original moving contact empty, thereby forming favorable conditions for the initial arrangement position of the moving reed assembly with a large working contact gap. On the premise of not significantly (or basically not) increasing the overall structural size of the clapper relay, a larger arrangement space is left for the moving reed assembly and the static reed assembly that form the working contact gap, which is beneficial for forming a larger working contact gap between the moving reed assembly and the static reed assembly of the clapper relay.

[0040] Furthermore, the area of the moving reed that is used for contact and cooperation with the limit buckle has convex buds formed by a convex structure. Based on the armature formed outside the contact side baffle by the limit buckle and the threading channel for the moving reed, in order to ensure the threading adaptability between the moving reed and the limit buckle within the threading channel, the convex bud structure stamped on the moving reed is used to adjust the threading gap for cooperation with the limit buckle, which has better flexibility. In addition, since the moving reed forms a line contact or point contact cooperation relationship with the limit buckle on the bobbin through the convex bud structure, the contact area between the moving reed and the limit buckle is small, which is beneficial to improving the phenomena of adhesion and ablation of the limit buckle caused by the high temperature generated by the current-carrying heating of the moving reed.

[0041] As one of the preferred technical solutions, the moving reed is used as the moving reed component of a double-break bridging type clapper relay. A first moving contact and a second moving contact are arranged at intervals in the contact part of the moving reed. The first moving contact on the moving reed corresponds to the first static contact of the first static reed component of the double-break bridging type clapper relay, and the second moving contact on the moving reed corresponds to the second static contact of the second static reed component of the double-break bridging type clapper relay;

[0042] In the working condition environment of the double-break bridging type clapper relay, the first static contact of the first static reed component and the second static contact of the second static reed component are on the same side of the contact part of the moving reed component. The moving reed component conducts / cuts off the current path between the first static reed component and the second static reed component in a bridging manner, and the moving reed of the moving reed component has a leadless structure.

[0043] The above technical measures are based on the moving reed with the above large elastic deformation amount and the limit buckle formed by an integral molding structure on the contact side baffle of the bobbin, which can restrict and limit the outward turning movement of the armature and the moving reed. Thus, the static reed component or positioning piece structure that originally restricted and limited the outward turning movement outside the moving reed component is directly cancelled, leaving the arrangement position of the static reed component or positioning piece outside the original moving contact empty. Furthermore, as the initial arrangement position of the moving reed component with a large working contact gap, without significantly (or basically not) increasing the overall structural size of the clapper relay, a relatively large arrangement space is left for the moving reed component and the static reed component that form the working contact gap. At the same time, the first static reed component and the second static reed component are respectively arranged on the same side of the moving reed component, with the first static reed component and the second static reed component forming the current path, and the suction / disconnection action of the moving reed component forming the on / off bridge of the current path between the first static reed component and the second static reed component. That is, the initial position of the moving reed component can be formed at the arrangement position of the static reed component or positioning piece outside the original moving contact, so that a large-gap fit is formed between the moving reed component and the inner first static reed component and the second static reed component (compared with the above-mentioned existing small clapper relay, the working contact gap can be increased by at least one time), to meet the technical requirements of the large current-carrying working condition environment.

[0044] In the technical measures of the above-mentioned double-break connection-bridge type clapper relay, two static reed assemblies arranged inside the moving reed assembly form the current path. There is no need for the moving reed of the moving reed assembly to form a through-body current-carrying pin anymore. Only the contact part of the moving reed serves as the current-carrying connection bridge between the two static reed assemblies, and no current-carrying function is required for the rest of the part. Therefore, the connection part of the moving reed assembly on the armature is not directly large-current-carrying, but only the contact part is radiated with current, which greatly reduces the temperature caused by the heat generated at the connection part of the moving reed on the armature. The lower heating temperature does not meet the technical conditions of bonding and ablation of the plastic limit buckle on the contact side baffle. That is to say, the moving reed of the present invention only serves as a current-carrying connection bridge between the two static reed assemblies of the above-mentioned double-break connection-bridge type clapper relay, and there is no technical requirement for through-body high-current-carrying. Therefore, the connection part between it and the armature has a lower heating temperature in the working condition environment. Thus, the limit buckle is formed on the coil bobbin in an integral molding structure, and the technical problem of the limit buckle being melted, adhered, and ablated will not occur. There is no need to additionally consider the molding material of the limit buckle or the combined molding structure on the coil bobbin, which not only meets the reliable limit of the outward turning movement of the moving reed, but also is easy to form efficiently and at low cost, effectively overcoming the technical prejudice that the contact limit of the outward turning movement of the moving reed assembly can only use metal parts.

[0045] In summary, the double-break connection-bridge type clapper relay including the moving reed of the present invention forms a large working contact gap applicable to a large-current-carrying working condition environment with a simple, compact, and small-sized structure without significantly changing the external structure dimensions of the relay product. The mature working condition equipment (such as the on-vehicle charging control box or charging gun of new energy vehicles) that originally used this type of relay can continue to be used, and basically no change to the mature working condition equipment at the user end will be involved due to the introduction of this type of relay, which is beneficial to market promotion.

[0046] The beneficial technical effects of the present invention are as follows: In view of the particularity of the above-mentioned small clapper relay, a through-hole structure elastic deformation groove is opened on the contact elastic deformation part of the moving reed, so that the main body structures of the two sides of the contact elastic deformation part under the action of the elastic deformation groove are bifurcated and supported between the armature connection part and the contact part. In particular, the contact elastic deformation part is formed in an isosceles trapezoid structure, which effectively reduces the structural stress of the elastic deformation. It can not only form good elastic deformation performance, effectively meet the technical requirements of durability, over-travel, and large working contact gap during service, but also enable the contact elastic deformation part to be formed between the armature connection part and the contact part with a relatively large structural size. Its structural rigidity is good, and it is not easy to have failure phenomena such as deformation and fracture during service, and the durability is good. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0056] The present utility model relates to a relay, specifically a moving contact spring structure for a clapper relay. The main technical solution content of the present utility model will be specifically described below in combination with multiple embodiments. Among them, Embodiment 1 is combined with the specification drawings - that is Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7Clearly and elaborately explain the technical solution content of the present utility model; although other embodiments are not separately illustrated, their main structures can still refer to the drawings of Embodiment 1.

[0057] It should be specifically noted here that the drawings of the present utility model are schematic. In order to clarify the technical purpose of the present utility model, unnecessary details have been simplified to avoid obscuring the technical solution contributed by the present utility model to the prior art. In addition, expressions such as "about" and "substantially" regarding quantity or mating relationship in the following text mean that reasonable assembly errors, processing errors, etc. in the industry are allowed, rather than absolute literal expressions of quantity or mating relationship.

[0058] Embodiment 1

[0059] See Figure 2 、 Figure 3 and Figure 4 As shown in, the moving reed 11 used in the clapper relay of the present utility model has an integrally formed yoke connection part 114, a suction spring force deformation part 115, an armature connection part 111, a contact spring force deformation part 112, and a contact part 113.

[0060] Specifically, the yoke connection part 114 of the moving reed 11 is used for fixed connection and cooperation with the yoke on the coil holder of the clapper relay. A plurality of riveting holes are provided in the central area of the yoke connection part 114. In addition, in order to enhance the connection strength and connection integrity between the yoke connection part 114 and the yoke, elastic buckles 118 that are folded inward toward the coil side are respectively formed at both side edges in the transverse width direction of the yoke connection part 114. The cooperation distance between the two elastic buckles 118 matches the transverse width dimension of the corresponding part of the yoke (i.e., the designed connection part between the yoke and the elastic buckle 118); each elastic buckle 118 is a hollow structure with a deformation through slot. At the front side of the deformation through slot (i.e., the side close to the coil), there is an inwardly folded convex forming (in the transverse width centripetal direction of the yoke) barb 119. The cooperation distance between the outer extension end of the barb 119 and the inner wall of the yoke connection part 114 matches the thickness dimension of the corresponding part of the yoke; the cooperation distance between the outer extension ends of the barbs 119 of the two elastic buckles 118 is smaller than the transverse width dimension of the corresponding part of the yoke. In this way, when the yoke connection part 114 is combined and connected with the yoke, the elastic buckles 118 on both sides of the yoke connection part 114 hold the yoke in the transverse width direction, and the outer extension end of the barb 119 of each elastic buckle 118 abuts against the inner wall of the yoke. At the same time, riveting connection is supplemented between the yoke connection part 114 and the yoke.

[0061] The suction elastic deformation part 115 is formed between the yoke connection part 114 and the armature connection part 111. The suction elastic deformation part 115 is used to ensure the flipping action of the armature at the yoke edge. Due to the approximate L-shaped fitting relationship between the armature and the yoke, the suction elastic deformation part 115 is an approximate L-shaped bending structure. And to enhance the elasticity, the suction elastic deformation part 115 is provided with a second elastic deformation groove 117 in the central area for the articulated part of the flipping action of the armature to be exposed at the moving contact spring 11. The second elastic deformation groove 117 is a rectangular structure, and its edge at the yoke connection part 114 should make the fitting structure of the armature at the yoke edge within the coverage of the second elastic deformation groove 117, and its edge at the armature connection part 111 should be close to the longitudinal middle of the armature.

[0062] The armature connection part 111 is used for fixed connection and cooperation with the armature. A plurality of riveting holes are provided in the central area of the armature connection part 111, and the armature connection part 111 is fixedly connected to the armature in a riveting relationship.

[0063] The contact elastic deformation part 112 is formed between the armature connection part 111 and the contact part 113, and is used to increase the over-travel elastic deformation of the contact part 113 during suction and enhance the structural rigidity. The transverse width dimensions of the contact elastic deformation part 112 are respectively smaller than those of the armature connection part 111 and the contact part 113. The two lateral edges of the transverse width of the contact elastic deformation part 112 form a lateral inward contraction between the armature connection part 111 and the contact part 113. The top view outer contour of the contact elastic deformation part 112 is an isosceles trapezoid shape, with its large end integrally connected to the armature connection part 111 and its small end integrally connected to the contact part 113. In the central area of the contact elastic deformation part 112, a first elastic deformation groove 116 matching the outer contour structure of the isosceles trapezoid is provided, that is, the contour of the first elastic deformation groove 116 is also an isosceles trapezoid shape, and the large end is close to the armature connection part 111 and the small end is close to the contact part 113. With this structure of the contact elastic deformation part 112, while increasing the deformation amount of the moving contact spring, it can also maintain high structural strength, so as to effectively prevent the moving contact spring from breaking and failing during repeated clapping in service, and at the same time is beneficial to the consistent action of the two moving contacts connected to the contact part 113, providing guarantee for the reliability of the following double-break bridge type clapping relay.

[0064] The contact part 113 is used to connect the moving contact. Based on the following double-break bridge type clapping relay to be formed, the contact part 113 of the moving contact spring 11 is used to arrange the first moving contact 12 and the second moving contact 13 at intervals.

[0065] See Figure 5 and Figure 6As shown, the moving reed 11 of the above structure is connected to the armature 5. Specifically, the armature connecting portion 111 is riveted to the armature 5. The front end of the armature 5 is located in the middle front part of the contact elastic deformation portion 112 in an arc profile, and the rear end of the armature 5 is located in the elastic deformation groove two 117 of the attracting elastic deformation portion 115 in a straight-edge structure.

[0066] See Figure 7 As shown, the clapper-type relay applicable to the moving reed 11 of the present utility model includes a bobbin 2, a static reed assembly one 3, a static reed assembly two 4, an armature 5, a yoke 6, an iron core 7, and a coil 8. The moving reed 11 of the present utility model cooperates with a moving contact one 12 and a moving contact two 13 to form a moving reed assembly 1.

[0067] Specifically, the bobbin 2 has an I-shaped structure and has a winding cylinder, a contact side baffle 21 formed by protruding outward with respect to the radial direction of the winding cylinder at one end of the winding cylinder, and a pin side baffle 22 formed by protruding outward with respect to the radial direction of the winding cylinder at the other end of the winding cylinder. The inside of the winding cylinder is used for assembling the iron core 7, and the outside of the winding cylinder is used for arranging the coil 8. The outside of the contact side baffle 21 is used for arranging the armature 5 and the moving reed assembly 1, and a contact point matching area is formed on the outside in front of the contact side baffle 21.

[0068] In order to realize the restraint and limit of the outward turning action of the armature 5 and the moving reed assembly 1 assembled on the outside of the contact side baffle 21, a pair of limit buckles 23 are formed in an integral molding structure on both sides in the transverse width direction of the contact side baffle 21, that is, the molding material of the limit buckles 23 is the same as that of the contact side baffle 21, both being plastic. Each side of the limit buckle 23 protrudes and forms from the outside of the contact side baffle 21, and has a folded edge at the outer end for forming a mounting channel for the armature 5 and the moving reed 11 on the outside of the contact side baffle 21, that is, each side of the limit buckle 23 has an inverted L-shaped structure. Since the limit buckle 23 of the foregoing structure is integrally injection molded with the bobbin 2 in a mold, in order to facilitate demolding and manufacturing, the limit buckle 23 has a draft angle in the demolding direction of the contact side baffle 21.

[0069] The iron core 7 is inserted into the winding cylinder of the bobbin 2, and the head end of the iron core 7 extends to the contact side baffle 21. The coil 8 is arranged on the winding cylinder of the bobbin 2. The yoke 6 is inserted and fixed on one side edge of the pin side baffle 22 of the bobbin 2 (if the contact point matching area is defined as the front side, the insertion position of the yoke 6 is at the rear side, the same below), vertically extends beside the coil 8, forms a spacing matching relationship with the coil 8, and the blade edge of the yoke 6 extends to the contact side baffle 21. The rear side of the contact side baffle 21 is the arrangement position of the blade edge of the yoke 6, the central area of the contact side baffle 21 is the insertion position of the iron core 7, and the front side of the contact side baffle 21 is the contact point matching area. The coil 8, the iron core 7, the yoke 6 on the foregoing bobbin 2 and the cooperating armature 5 below constitute a magnetic circuit part.

[0070] Static spring assembly 1 (3) and static spring assembly 2 (4) have the same structure, but they are formed as relatively independent structures. The yoke 6 arrangement and contact mating area are defined as the longitudinal direction in the fore-aft direction. The direction perpendicular to the longitudinal direction is the transverse direction in the left-right direction. Based on the transverse width of the coil bobbin 2, static spring assembly 1 (3) and static spring assembly 2 (4) are separately assembled on either side of the contact-side baffle 21. More specifically, static spring assembly 1 (3) comprises a static spring piece 1 (31). The contact portion of static spring piece 1 (31) is formed in a bent structure and is arranged on the left side of the contact-side baffle 21 (note that this is only a relative representation with reference to the drawings, not an absolute position, the same applies below). The static contact 1 (32) to which the contact portion of static spring piece 1 (31) is connected is also arranged on the left side of the contact-side baffle 21. The main body of static spring piece 1 (31) extends vertically through the contact-side baffle 21 toward the pin-side baffle 22. Static spring pin 1 (33) of static spring piece 1 (31) extends vertically through the pin-side baffle 22. The static spring assembly 2 4 has a static spring piece 2 41 , the contact portion of the static spring piece 2 41 is formed with a bent structure, and is arranged on the right side of the outer side of the contact side baffle 21 . The static contact 2 42 connected to the contact portion of the static spring piece 2 41 is also arranged on the right side of the outer side of the contact side baffle 21 ; the main part of the static spring piece 2 41 vertically passes through the contact side baffle 21 and extends toward the pin side baffle 22 , and the static spring pin 2 43 of the static spring piece 2 41 vertically passes through the pin side baffle 22 .

[0071] The assembly structure of the aforementioned static spring assembly 1 3 and static spring assembly 2 4 on the coil bobbin 2 ensures that the static contact 1 32 of static spring assembly 1 3 and the static contact 2 42 of static spring assembly 2 4 are arranged within the contact mating area outside the contact-side baffle 21, maintaining substantially the same height. To increase the creepage distance between static contacts 1 32 and 2 42 outside the contact-side baffle 21 and prevent contact splashes from causing non-technical conduction between them, a contact retaining wall 24 is protruded in the contact mating area of the contact-side baffle 21, integrally formed with the contact-side baffle 21, located between the static contact 1 32 of static spring assembly 1 3 and the static contact 2 42 of static spring assembly 2 4. The lowest protrusion height of this contact retaining wall 24 is slightly higher than the highest points of static contacts 1 32 and 2 42. Of course, the highest protrusion height of the contact retaining wall 24 on the contact side baffle 21 should not affect the bridge matching relationship between the following dynamic spring assembly 1 and the aforementioned static spring assembly 1 3 and static spring assembly 2 4, that is, when the dynamic contact 1 12 and the static contact 1 32, and the dynamic contact 2 13 and the static contact 2 42 of the following dynamic spring assembly 1 are correspondingly attracted, the contact retaining wall 24 should not cause abutment obstruction to the contact portion 113 of the dynamic spring piece 11, but maintain a spacing match with the contact portion 113 of the dynamic spring piece 11.

[0072] The armature 5 is connected to the knife edge of the yoke 6 through the moving contact spring piece 11 of the moving contact spring assembly 1. Under the action of the elastic force of the moving contact spring piece 11 and the suction force of the magnetic circuit part, the armature 5 is assembled outside the contact side baffle 21 in a flip - over structure, forming a hinge - shaft fit with the knife edge of the yoke 6. The length that the armature 5 extends from the yoke 6 towards the contact - mating area side should be able to cover the head end of the iron core 7 through which the bobbin 2 is inserted. Of course, it should form a spacing fit with the contact - mating area on the front side of the contact side baffle 21. To fit with the head end of the iron core 7 and avoid position interference, the front end of the armature 5 is formed in an arc structure and is located in the middle front part of the contact elastic - deformation part 112 of the above - mentioned moving contact spring piece 11.

[0073] The moving contact spring piece 11 of the moving contact spring assembly 1 is connected between the yoke 6 and the armature 5, and its contact part 113 extends towards the contact - mating area of the contact side baffle 21. That is, the yoke - connecting part 114 of the moving contact spring piece 11 forms a fixed - connection fit with the yoke 6, and the armature - connecting part 111 of the moving contact spring piece 11 forms a fixed - connection fit with the armature 5. Thus, it is assembled between the yoke 6 and the armature 5 in a bent structure and moves with the armature 5.

[0074] The contact part 113 of the moving contact spring piece 11 is located above both the fixed contact 32 of the first fixed - contact spring assembly 3 and the fixed contact 42 of the second fixed - contact spring assembly 4. Its initial position outside the contact side baffle 21 is basically at the position of the first fixed - contact spring assembly 3' mentioned in the above - mentioned background - technology part. The moving contact 12 connected to the contact part 113 of the moving contact spring piece 11 corresponds to the fixed contact 32 of the first fixed - contact spring assembly 3 in the up - down position (that is, along the spacing arrangement direction of the contact side baffle 21 and the pin - side baffle 22, with the contact side baffle 21 as the upper side and the pin - side baffle 22 as the lower side), and the moving contact 13 connected to the contact part 113 of the moving contact spring piece 11 corresponds to the fixed contact 42 of the second fixed - contact spring assembly 4 in the up - down position. Through the above - mentioned cooperation relationship, both the fixed contact 32 of the first fixed - contact spring assembly 3 and the fixed contact 42 of the second fixed - contact spring assembly 4 are arranged inside the moving contact spring assembly 1, and the fixed contact 32 of the first fixed - contact spring assembly 3 and the fixed contact 42 of the second fixed - contact spring assembly 4 are arranged in a spaced - apart relationship in the inner - side contact - mating area of the moving contact spring assembly 1.

[0075] The clapper - type relay with the above - mentioned structure has the technical characteristics of simple structure, compact structure, and small volume as mentioned in the above - mentioned background - technology part. In the working condition environment:

[0076] The first fixed - contact spring pin 33 of the first fixed - contact spring assembly 3 is used to introduce current, and the second fixed - contact spring pin 43 of the second fixed - contact spring assembly 4 is used to lead out current; or vice versa, the second fixed - contact spring pin 43 of the second fixed - contact spring assembly 4 is used to introduce current, and the first fixed - contact spring pin 33 of the first fixed - contact spring assembly 3 is used to lead out current; It can be seen that in this embodiment, the moving contact spring piece 11 does not need to form a pin structure;

[0077] When the exciting current of the magnetic circuit part rises to the set value, the armature 5 is attracted and closed at the head end of the iron core 7. At this time, the moving contact piece 11 of the moving contact assembly 1 conducts the static contact assembly 1 and the static contact assembly 2 through the attraction of the first moving contact 12 and the first static contact 32 and the attraction of the second moving contact 13 and the second static contact 42;

[0078] When the exciting current of the magnetic circuit part drops to the set value, the armature 5 disconnects from the head end of the iron core 7 under the elastic force of the moving contact piece 11 of the moving contact assembly 1. At this time, the moving contact piece 11 of the moving contact assembly 1 cuts off the static contact assembly 1 and the static contact assembly 2 through the disconnection of the first moving contact 12 and the first static contact 32 and the disconnection of the second moving contact 13 and the second static contact 42.

[0079] From the working process of the above-mentioned clapper relay, it can be seen that the moving contact piece 11 driven by the armature 5 has a flipping action of attraction / disconnection outside the contact side baffle 21, and the flipping action is restricted and limited by the limit buckle 23 on the contact side baffle 21.

[0080] Since a mounting channel for the armature 5 and the moving contact piece 11 is formed between the folded edge of the limit buckle 23 and the outside of the contact side baffle 21, and the size of this channel is basically determined and cannot be changed. In order to make the moving contact piece 11 mounted therein adapt to the gap of this mounting channel, it is necessary to enhance its adaptability flexibility from the moving contact piece 11. Therefore, a convex bract 1110 with a convex structure is formed by stamping in the area where the moving contact piece 11 is used to contact and cooperate with the folded edge of the limit buckle 23. The moving contact piece 11 mounted at the limit buckle 23 on the contact side baffle 21 contacts and cooperates with the folded edge of the corresponding limit buckle 23 through the convex bracts 1110 on both sides of the transverse width direction of the armature connecting part 111. This cooperation structure can also reduce the limited contact surface of the moving contact piece 11. On the one hand, it is beneficial to ensure the elastic deformation ability, and on the other hand, it is beneficial to ensure the durability of the limit buckle 23, especially anti-sticking.

[0081] Embodiment 2

[0082] The moving contact piece of the present utility model for a clapper relay has an integrally formed yoke iron connecting part, an attracting elastic deformation part, an armature connecting part, a contact elastic deformation part and a contact part.

[0083] Specifically, the yoke connection part of the moving reed is used for fixed connection and cooperation with the yoke on the coil holder of the clapper relay. A plurality of riveting holes are provided in the central area of the yoke connection part. In addition, to enhance the connection strength and integrity between the yoke connection part and the yoke, elastic buckles that are folded inward toward the coil side are respectively formed at the two side edges in the transverse width direction of the yoke connection part. The cooperation distance between the two elastic buckles matches the transverse width dimension of the corresponding part of the yoke (i.e., the designed connection part between the yoke and the elastic buckle); each elastic buckle is of a hollow structure and has a deformation through groove. At the front side of the deformation through groove (i.e., the side close to the coil), there is an inwardly folded barb formed (in the transverse width centripetal direction of the yoke). The cooperation distance between the outer extension end of the barb and the inner wall of the yoke connection part matches the thickness dimension of the corresponding part of the yoke; the cooperation distance between the outer extension ends of the barbs on the two elastic buckles is less than the transverse width dimension of the corresponding part of the yoke. In this way, when the aforementioned yoke connection part is combined and connected with the yoke, the elastic buckles on both sides of the yoke connection part hold the yoke in the transverse width direction, and the outer extension ends of the barbs on each elastic buckle abut against the inner wall of the yoke. At the same time, riveting connection is used between the yoke connection part and the yoke.

[0084] The suction elastic deformation part is formed between the yoke connection part and the armature connection part. The suction elastic deformation part is used to ensure the flipping action of the armature at the yoke blade edge. Due to the approximate L-shaped cooperation relationship between the armature and the yoke, the suction elastic deformation part is of an approximate L-shaped bending structure. And to enhance the elasticity, a second elastic deformation groove for the flipping action hinge part of the armature to be exposed at the moving reed is provided in the central area of the suction elastic deformation part. The second elastic deformation groove is of a rectangular structure. Its edge at the yoke connection part should make the cooperation structure between the armature and the yoke blade edge within the coverage of the second elastic deformation groove, and its edge at the armature connection part should be close to the longitudinal middle of the armature.

[0085] The armature connection part is used for fixed connection and cooperation with the armature. A plurality of riveting holes are provided in the central area of the armature connection part, and the armature connection part is fixedly connected to the armature in a riveting relationship.

[0086] The contact elastic deformation part is formed between the armature connection part and the contact part, and is used to increase the over-travel elastic deformation of the contact part during suction and enhance the structural rigidity. The transverse width dimension of the contact elastic deformation part is smaller than that of the armature connection part and the contact part respectively. The two side edges of the transverse width of the contact elastic deformation part form a transverse inward contraction between the armature connection part and the contact part respectively. The top view outer contour of the contact elastic deformation part is in the shape of an isosceles trapezoid, with its large end integrally connected to the armature connection part and its small end integrally connected to the contact part. In the central area of the contact elastic deformation part, an elastic deformation groove 1 matching the outer contour structure of the isosceles trapezoid is provided, that is, the contour of the elastic deformation groove 1 is also in the shape of an isosceles trapezoid, and the large end is close to the armature connection part and the small end is close to the contact part. The contact elastic deformation part with this structure can increase the deformation amount of the moving reed while maintaining high structural strength, so as to effectively prevent the moving reed from breaking and failing during repeated clapping in service.

[0087] The contact part is used to connect the moving contact.

[0088] The moving reed with the above structure is connected to the armature. Specifically, the armature connection part is riveted to the armature. The front end of the armature is at the middle front part of the contact elastic deformation part with an arc contour, and the rear end of the armature is at the elastic deformation groove 2 of the suction elastic deformation part with a straight edge structure.

[0089] The clapper relay applicable to the moving reed of the present invention includes a bobbin, a static reed assembly 1, a static reed assembly 2, an armature, a yoke, an iron core and a coil. The moving reed of the present invention cooperates with the moving contact to form a moving reed assembly.

[0090] Specifically, the bobbin is of an I-shaped structure, having a winding cylinder, a contact side baffle formed by protruding outward compared with the radial direction of the winding cylinder at one end of the winding cylinder, and a pin side baffle formed by protruding outward compared with the radial direction of the winding cylinder at the other end of the winding cylinder. The inside of the winding cylinder is used to assemble the iron core, and the outside of the winding cylinder is used to arrange the coil. The outside of the contact side baffle is used to arrange the armature and the moving reed assembly, and a contact matching area is formed on the outside in front of the contact side baffle.

[0091] The iron core is inserted into the winding cylinder of the bobbin, and the head end of the iron core extends to the contact side baffle. The coil is arranged on the winding cylinder of the bobbin. The yoke is inserted and fixed at one side edge of the pin side baffle of the bobbin (if the contact matching area is defined as the front side, the insertion position of the yoke is at the rear side, the same below), vertically extends beside the coil, forms a spacing matching relationship with the coil, and the blade of the yoke extends to the contact side baffle. The rear side of the contact side baffle is the arrangement position of the yoke blade, the central area of the contact side baffle is the insertion position of the iron core, and the front side of the contact side baffle is the contact matching area. The coil, iron core, yoke on the above-mentioned bobbin and the cooperating armature constitute the magnetic circuit part.

[0092] The structures of the first static spring component and the second static spring component are basically the same, but they are formed in a relatively independent structure. The above defines the arrangement position of the yoke iron and the contact matching area longitudinally in the front-back position. Then, the direction perpendicular to the longitudinal direction is the left-right lateral direction. Based on the transverse width direction of the bobbin, the first static spring component and the second static spring component are separately assembled on both sides of the transverse width direction of the contact side baffle. More specifically, the first static spring component has a first static spring piece. The contact part of the first static spring piece is formed in a bent structure and is arranged at the left position outside the contact side baffle (note that this is only a relative expression for reference to the attached drawing, not an absolute position, the same below). The first static contact connected to the contact part of the first static spring piece is also arranged at the left position outside the contact side baffle. The main body part of the first static spring piece vertically penetrates the contact side baffle and extends towards the pin side baffle. The first static spring pin of the first static spring piece vertically penetrates out from the pin side baffle. The contact part of the first static spring piece is outside the contact part of the moving spring piece, that is, the first static contact connected to the first static spring piece is outside the contact part of the moving spring piece, as shown in the structure of the background art part. The second static spring component has a second static spring piece. The contact part of the second static spring piece is formed in a bent structure and is arranged at the right position outside the contact side baffle. The second static contact connected to the contact part of the second static spring piece is also arranged at the right position outside the contact side baffle. The main body part of the second static spring piece vertically penetrates the contact side baffle and extends towards the pin side baffle. The second static spring pin of the second static spring piece vertically penetrates out from the pin side baffle. The contact part of the second static spring piece is inside the contact part of the moving spring piece, that is, the second static contact connected to the second static spring piece is inside the contact part of the moving spring piece, as shown in the structure of the background art part.

[0093] The above assembly structure of the first static spring component and the second static spring component on the bobbin enables the first static contact of the first static spring component and the second static contact of the second static spring component to be respectively arranged in the contact matching area outside the contact side baffle and at different axial heights.

[0094] The armature is connected to the edge of the yoke iron through the moving spring piece of the moving spring component and is assembled outside the contact side baffle in a flipable structure under the action of the elastic force of the moving spring piece and the suction force of the magnetic circuit part, forming a hinge shaft fit with the edge of the yoke iron. The length of the armature extending from the yoke iron towards the contact matching area side should be able to cover the head end of the iron core through which the bobbin is inserted. Of course, it should form a spacing fit with the contact matching area in front of the contact side baffle. To fit with the head end of the iron core and avoid position interference, the front end of the armature is formed in an arc structure and is at the middle front part of the elastic deformation part of the contact of the above moving spring piece.

[0095] The moving spring piece of the moving spring component is connected between the yoke iron and the armature and makes its contact part extend towards the contact matching area of the contact side baffle. That is, the yoke iron connecting part of the moving spring piece forms a fixed connection fit with the yoke iron, and the armature connecting part of the moving spring piece forms a fixed connection fit with the armature. Thus, it is assembled between the yoke iron and the armature in a bent structure and follows the armature.

[0096] The contact portion of the moving reed is axially between the first stationary contact of the first stationary reed assembly and the second stationary contact of the second stationary reed assembly, as described in the background art section. The moving contact connected to the contact portion of the moving reed is vertically corresponding to the first stationary contact of the first stationary reed assembly and the second stationary contact of the second stationary reed assembly.

[0097] In the above-mentioned clapper-type relay structure, the moving contact of the moving reed assembly forms a normally open cooperation relationship with the second stationary contact of the second stationary reed assembly and a normally closed cooperation relationship with the first stationary contact of the first stationary reed assembly, and is restricted and positioned by the first stationary reed assembly. Therefore, the moving reed of the moving reed assembly needs to form a pin structure to carry current.

[0098] For the clapper-type relay with the above structure, in the working condition environment:

[0099] The first stationary reed assembly only restricts and positions without carrying current;

[0100] The second stationary reed pin of the second stationary reed assembly is used to introduce current, and the pin of the moving reed assembly is used to lead out current; or vice versa, the pin of the moving reed assembly is used to introduce current, and the second stationary reed pin of the second stationary reed assembly is used to lead out current;

[0101] When the exciting current of the magnetic circuit part rises to the set value, the armature is attracted at the head end of the iron core. At this time, the moving reed of the moving reed assembly is attracted to the second stationary contact of the second stationary reed assembly through the moving contact and disconnected from the first stationary contact of the first stationary reed assembly;

[0102] When the exciting current of the magnetic circuit part drops to the set value, the armature is disconnected from the head end of the iron core under the elastic force of the moving reed of the moving reed assembly. At this time, the moving reed of the moving reed assembly is disconnected from the second stationary contact of the second stationary reed assembly through the moving contact and attracted to the first stationary contact of the first stationary reed assembly, and is restricted and positioned by the first stationary reed assembly.

[0103] Embodiment 3

[0104] Other contents of this embodiment are the same as those of Embodiment 1 or Embodiment 2, the difference is that:

[0105] The top view outer contour of the contact elastic deformation part of the moving reed is rectangular;

[0106] Correspondingly, in the central area of the rectangular contact elastic deformation part, a first elastic deformation groove with a rectangular contour structure is provided.

[0107] Although this embodiment can achieve a certain technical effect of ensuring elastic deformation, it is less effective in reliably ensuring the durability structural strength and elastic deformation of the moving reed than the isosceles trapezoid structure of Embodiment 1 or Embodiment 2.

[0108] Embodiment 4

[0109] Other contents of this embodiment are the same as those of Embodiment 1 or Embodiment 2, the difference being that:

[0110] The moving reed is only composed of an integral armature connecting part, a contact elastic deformation part and a contact part;

[0111] As for the elastic connection between the yoke and the armature, it is formed by another reed structure independent of the moving reed. Of course, it can also have an integrally formed yoke connecting part, an attracting elastic deformation part and an armature connecting part as described in Embodiment 1 / Embodiment 2. The armature connecting parts between the two reeds are close but disconnected and independent of each other.

[0112] Although this embodiment can achieve the technical purpose of the present utility model, the simplicity and reliability of its structure are obviously inferior to those of Embodiment 1 / Embodiment 2.

[0113] The above embodiments are only used to illustrate the present utility model and are not intended to limit it.

[0114] Although the present utility model has been described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that: they can still modify the above embodiments, or perform equivalent replacements on some of the technical features. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the present utility model.
