Description

Technical Field

[0001] This utility model relates to the field of electromagnetic relay technology, specifically a connection structure between an electromagnetic relay reed and a base, and an electromagnetic relay including the connection structure. Background Technology

[0002] In the structure of an electromagnetic relay, there is a magnetic circuit part and a contact part that mate on a base. The contact part is mainly composed of a moving spring assembly and a stationary spring assembly. To achieve miniaturization of this type of electromagnetic relay while meeting the relative mating clearance requirements, the moving spring assembly, which connects to the magnetic circuit part, needs a necessary clearance structure design. That is, the moving spring needs to form a distance with the magnetic circuit part that meets the requirements of the actuation technology, and the leads of the moving spring need to be staggered from the leads of the stationary spring. This allows the moving spring of the miniaturized electromagnetic relay to be assembled on the base with a bent clearance structure. This is particularly prominent in the structure of ultra-miniature push-rod electromagnetic relays, such as... Figure 1 As shown.

[0003] exist Figure 1 In the structure of the ultra-miniature push rod electromagnetic relay shown, the moving spring A, which makes up the contact part, has a mounting structure arrangement position in the height direction between the pin and the contact connection position, which is formed by bending. In the horizontal direction of the base B, there is a spring assembly arrangement position between the magnetic circuit part and the stationary spring, which is used to assemble the moving spring A. The spring assembly arrangement position of the base B has a moving spring pin socket near the magnetic circuit part. In the assembly structure between the movable spring A and the base B, the movable spring pin of the movable spring A passes through the corresponding movable spring pin insertion hole on the base B. The movable spring A is assembled on the spring assembly arrangement position of the base B through the bent structure mounting arrangement position. When the movable spring A is assembled in place on the base B, the mounting structure arrangement position of the movable spring A and the spring assembly arrangement position of the base B are in surface contact. Moreover, the mounting structure arrangement position and the spring assembly arrangement position form a transverse mating section between the movable spring A and the base B in the horizontal direction of the base B. This transverse mating section is bent in both the horizontal and vertical directions relative to the direction of the movable spring pin insertion hole on the base B, forming a non-linear axial structure.

[0004] The assembly structure between the moving spring and the base, as described above, needs to have good rigidity. To achieve this technical objective, two technical methods are currently employed: Firstly, the moving spring is inserted into the moving spring pin socket and spring assembly arrangement position of the base with a tight fit structure; however, this technique cannot reliably guarantee the assembly firmness for a long time, and secondly, it is easy to generate scratches and lint that affect the conduction during tight fit assembly, which is not conducive to maintaining the performance of the finished electromagnetic relay. Secondly, the moving spring is loosely inserted into the moving spring pin socket and spring assembly arrangement position of the base, and fixed by dispensing adhesive. However, this technique is limited by the obstruction of the lateral mating section assembly structure between the moving spring and the base. The dispensing is performed at the contour joint of the assembly structure between the moving spring and the base. On the one hand, it is difficult for this dispensing to flow to the mating surface between the moving spring and the base, especially the mating surface of the lateral mating section, so the stability of the firmness cannot be effectively guaranteed. On the other hand, the needle of the automatic dispensing machine cannot effectively adapt to the dispensing trajectory and action, and cannot effectively meet the needs of automated assembly operations, thus increasing the manufacturing cost of the electromagnetic relay.

[0005] In summary, given the unique assembly structure between the moving spring and the base of the aforementioned ultra-miniature electromagnetic relay, it is necessary to optimize the design to ensure assembly firmness, reduce assembly debris, and meet the requirements of automated assembly operations. Utility Model Content

[0006] The technical objective of this utility model is to provide a connection structure between the spring and the base of an electromagnetic relay that can ensure assembly firmness, reduce assembly debris, and meet the requirements of automated assembly operations, in view of the special assembly structure between the spring and the base of the aforementioned ultra-miniature electromagnetic relay and the shortcomings of the prior art, as well as an electromagnetic relay including the connection structure.

[0007] The technical objective of this utility model is achieved through the following technical solution: a connection structure between an electromagnetic relay spring and a base, comprising a base and a first spring forming the contact part of the electromagnetic relay. In the assembly structure between the first reed and the base, the base has a transverse mating section in the horizontal direction; The first spring at the transverse mating section has an injection hole that extends through the thickness direction of the first spring. On the base at the transverse mating section, at least one glue-permeable seam is formed with an inwardly recessed structure, which can connect to the glue injection hole and extends at the mating surface of the transverse mating section. The adhesive injected through the injection hole is distributed to the transverse mating section through the adhesive penetration joint.

[0008] Specifically, the base has a spring assembly arrangement position for assembling the first spring in the horizontal direction; In the height direction of the first reed, there is a mounting structure arrangement that is located between the pin and the contact connection position, is formed by bending, and is adapted to the assembly arrangement of the reed; In the assembly structure between the first spring and the base, the first spring is assembled on the spring assembly arrangement position of the base through the mounting structure arrangement position. When the first spring is assembled in place on the base, the mounting structure arrangement position of the first spring and the spring assembly arrangement position of the base are in surface contact. The mounting structure arrangement position and the spring assembly arrangement position form a transverse mating section between the first spring and the base in the horizontal direction of the base. The mounting structure of the first spring has an injection hole that extends through the thickness direction of the first spring. On the spring assembly arrangement position of the base, at least one glue-permeable seam is formed with an inwardly recessed structure, which can connect to the glue injection hole and extends at the joint surface between the mounting structure arrangement position and the spring assembly arrangement position.

[0009] The aforementioned technical measures address the unique assembly structure of the reed and base in the ultra-miniature electromagnetic relay. An injection hole is provided on the reed at its transverse mating section, and an adhesive penetration seam is provided on the base, connecting the injection hole and extending to the mating surface of the transverse mating section. This allows adhesive to be applied through the injection hole on the reed, which then seeps through the adhesive penetration seam on the base to the mating surface of the transverse mating section between the reed and base. This effectively achieves bonding at the mating surface of the transverse mating section, reliably ensuring the strong assembly of the reed and base. Furthermore, the simple and clear injection hole on the reed effectively accommodates the needle dispensing of an automatic dispensing machine, thus facilitating automated assembly operations during reed assembly, improving assembly efficiency and reducing costs. Furthermore, based on the above-mentioned assembly structure in which the spring and the base are bonded with adhesive at the lateral mating section, the spring and the base can be assembled with a loose fit structure before adhesive bonding, so as to avoid the scratches and lint that are unavoidable during tight fit assembly, provided that good assembly firmness is achieved.

[0010] Therefore, the above-mentioned technical measures can not only reliably ensure the assembly firmness between the spring and the base, but also reduce the generation of lint during assembly between the spring and the base, and effectively meet the automated assembly operation of the spring on the base, with remarkable results.

[0011] As one of the preferred technical solutions, the base is also formed with an inner concave structure to form a glue-closing groove that connects each glue-dipping seam; At the transverse mating section, the glue injection hole of the first spring and the glue distribution groove of the base are connected in the height direction of the base.

[0012] The aforementioned technical measures connect the glue-applying seams on the base with glue-applying grooves arranged around the center, thereby facilitating the relatively uniform flow and distribution of the glue entering the glue-applying grooves within each seam. Furthermore, the series of glue-applying seams connected around the glue-applying grooves ensures that each seam connects evenly with the glue injection holes on the spring, and that the distribution at the mating surface of the transverse mating section is relatively uniform. Therefore, these technical measures not only facilitate the connection between the glue-applying seams and the glue injection holes on the spring, resulting in a simple and easy-to-implement molding structure, but also improve the assembly firmness between the spring and the base by ensuring a relatively uniform and comprehensive distribution of the glue.

[0013] Furthermore, the diameter of the adhesive groove on the base is larger than the diameter of the adhesive injection hole of the first spring. In the height direction of the base, the glue injection hole is located within the orthographic projection coverage area of ​​the glue application groove.

[0014] The above technical measures are based on the relative positional relationship between the glue distribution groove on the base and the glue injection hole on the spring, as well as the effect on each glue penetration joint, so that the glue injected by the glue injection hole can enter each glue penetration joint relatively quickly and fully through the glue distribution groove, and the glue has good fluidity and distribution.

[0015] Furthermore, the adhesive penetration seams on the base are linear structures, and these seams are arranged radially around the circumference of the adhesive groove. This technical measure facilitates the rapid and sufficient flow of adhesive, facilitates the processing and shaping on the base, and promotes a relatively uniform and comprehensive distribution at the mating surface of the transverse mating section. This, in turn, facilitates the rapid and thorough completion of the adhesive injection operation and improves the assembly firmness between the spring and the base.

[0016] As one of the preferred technical solutions, the transverse mating section is formed in the horizontal direction of the base with a planar structure, an inclined structure, and / or a curved surface structure. This technical measure is determined based on the assembly design structure between the spring and the base. The glue injection structure space formed by the transverse mating section between the spring and the base can realize glue injection at the mating surface, which is beneficial to improving the assembly firmness between the spring and the base. Of course, when the base is in a horizontal state, the planar structure glue injection space at the transverse mating section is conducive to the natural flow of the injected glue; if the glue injection space at the transverse mating section has a curved or inclined structure, it needs to be coordinated with the glue flow action of rotating the base to achieve sufficient distribution of glue in each glue penetration joint.

[0017] As one of the preferred technical solutions, the base at the transverse mating section has at least one limiting protrusion with an outwardly convex structure; Correspondingly, the first reed has a limiting notch adapted to the limiting protrusion; When the first spring is assembled into place on the base, the limiting notch on the first spring engages with the corresponding limiting protrusion on the base.

[0018] The above-mentioned technical measures, based on the glue injection space, precisely position the assembly between the spring and the base using a limiting structure, which not only enhances the assembly firmness of the spring on the base, but also ensures the assembly accuracy of the spring on the base.

[0019] Furthermore, the limiting protrusions on the base are in two sets, respectively located on both sides of the base in the width direction of the first spring. Correspondingly, the limiting notch on the first reed is a C-shaped contour structure adapted to the corresponding limiting protrusion.

[0020] The above-mentioned technical measures, while achieving precise positioning between the spring and the base, help to eliminate the interference of the limiting structure on the glue injection space. In other words, it is conducive to the glue injection space and the limiting structure being formed together at the assembly point of the spring and the base, which is easy to implement.

[0021] An electromagnetic relay has a base and a magnetic circuit portion and a contact portion mounted on the base; The contact portion has a movable spring sheet that forms part of the movable spring assembly; The assembly structure of the movable spring on the base is any of the above-mentioned connection structures between the spring and the base.

[0022] Furthermore, the electromagnetic relay is a push rod type electromagnetic relay, having a base and a magnetic circuit part, a contact part, and a push clip between the armature in the magnetic circuit part and the moving spring in the contact part mounted on the base.

[0023] The moving reed of the aforementioned electromagnetic relay adopts the assembly structure between the reed and the base, which not only meets the design requirements of the electromagnetic relay for miniaturization, but also has the technical advantages of the assembly structure between the reed and the base. This ensures the reliable assembly strength between the moving reed and the base, and facilitates the automation of the assembly operation of the moving reed on the base.

[0024] The beneficial technical effects of this utility model are as follows: Addressing the unique characteristics of ultra-miniature electromagnetic relays, especially ultra-miniature push-rod type electromagnetic relays, the above-mentioned technical measures include an injection hole on the spring and an adhesive penetration seam on the base between the spring with a transverse assembly section. When properly assembled, the adhesive penetration seam connects to the injection hole and extends to the mating surface of the transverse assembly section. Thus, in the assembly structure between the spring and the base, by applying adhesive through the injection hole on the spring, the applied adhesive can seep through the adhesive penetration seam on the base to the mating surface of the transverse mating section between the spring and the base, effectively achieving adhesion at the mating surface of the transverse mating section between the spring and the base, reliably ensuring the firmness of the assembly between the spring and the base. Simultaneously, the above-mentioned technical measures create a simple and clear injection hole on the spring, which can effectively adapt to the needle dispensing of an automatic dispensing machine, thereby effectively meeting the automated assembly operation of automatic dispensing in spring assembly, which is beneficial for improving spring assembly efficiency and reducing costs. Furthermore, based on the above-mentioned assembly structure in which the spring and the base are bonded with adhesive at the lateral mating section, the spring and the base can be assembled with a loose fit structure before adhesive bonding, so as to avoid the scratches and lint that are unavoidable during tight fit assembly, provided that good assembly firmness is achieved.

[0031] This utility model relates to the field of electromagnetic relay technology, specifically a connection structure between an electromagnetic relay spring and a base, and an electromagnetic relay including this connection structure. The main technical solution of this utility model will be described in detail below with reference to several embodiments. Embodiment 1 is illustrated in conjunction with the accompanying drawings—that is… Figure 2 , Figure 3 , Figure 4 and Figure 5 The technical solution of this utility model is clearly and in detail explained; although other embodiments are not shown in separate drawings, their main structure can still be referred to the drawings of Embodiment 1.

[0032] It should be noted that the accompanying drawings of this utility model are schematic, and unnecessary details have been simplified to clarify the technical purpose of this utility model, so as to avoid obscuring the technical solution contributed by this utility model to the prior art. In addition, the expressions such as "about" and "basically" regarding quantity or fit relationship in the following text mean that reasonable assembly errors and processing errors are allowed in the industry, and do not literally describe absolute quantity or fit relationship.

[0033] Example 1 See Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the electromagnetic relay of this utility model is an ultra-miniature push rod type electromagnetic relay, which mainly consists of a base 2 and a magnetic circuit part (including coil frame, coil, iron core, yoke, armature, compression spring, etc.) assembled on the base 2, a contact part (including moving spring assembly and stationary spring assembly, wherein the moving spring assembly has a moving spring plate - i.e., the first spring plate 1 hereinafter referred to as the moving contact, and the stationary spring assembly has a stationary spring plate and a stationary contact), and a pusher between the armature in the magnetic circuit part and the moving spring plate in the contact part, etc.

[0034] In the structure of the electromagnetic relay described above, the moving reed is the first reed 1 described below. In other words, unless otherwise specified, the first reed 1 described below is the moving reed of the electromagnetic relay described above.

[0035] In the aforementioned electromagnetic relay structure, to accommodate ultra-miniaturization, the first spring 1, which forms the contact portion and connects to the magnetic circuit portion via a push card, is designed with a clearance structure. Specifically, the first spring 1 has a bent mounting structure arrangement position 11 in the height direction, positioned between the pin and the contact connection position. Correspondingly, on the top surface of the base 2 (with... Figure 5Based on the indicated position, the horizontal direction is the horizontal direction of the base 2, the vertical direction is the height direction, and the front-to-back direction is the width direction; in the height direction, there is a top surface and a bottom surface). A spring assembly arrangement position 21 is provided with an inward structure between the stationary springs of the magnetic circuit part and the contact part for assembling the first spring 1. The spring assembly arrangement position 21 is basically formed in a planar structure in the horizontal direction of the base 2. The aforementioned spring assembly arrangement position 21 of the base 2 has a pin insertion hole 22 that penetrates the top surface and the bottom surface at a corner near the magnetic circuit part. The first spring 1 of the aforementioned structure is assembled on the spring assembly arrangement position 21 of the aforementioned base 2 through the bent mounting structure arrangement position 11. Specifically, the first spring 11 is inserted downward through the pin on the top side of the base 2, so that the pin of the first spring 1 passes through the corresponding pin insertion hole 22 on the base 2, until the mounting structure arrangement position 11 of the first spring 1 is located in the spring assembly arrangement position 21 of the base 2 and is limited and assembled in place. At this time, the mounting structure arrangement position 11 of the first spring 1 and the spring assembly arrangement position 21 of the base 2 form a part that basically cooperates in a surface contact manner. This part constitutes the transverse cooperation section between the first spring 1 and the base 2 in the horizontal direction of the base 2. The transverse cooperation section is bent in the horizontal and vertical direction relative to the pin insertion hole 22 on the base 2, and is a non-linear axial structure. The first spring 1, assembled on the base 2 in this way, forms a spacing that meets the design technical requirements with the magnetic circuit part, and also staggers the arrangement distance between the pins of other springs (stationary springs) that need to cooperate.

[0036] To ensure the robustness of the assembly structure between the first spring 1 and the base 2, adhesive bonding is required at the mating surface between the mounting structure arrangement 11 of the first spring 1 and the spring assembly arrangement 21 of the base 2. Due to the lateral assembly structure of the mounting structure arrangement 11 of the first spring 1 and the spring assembly arrangement 21 of the base 2 in the horizontal direction of the base 2, the following adhesive bonding and seepage structure needs to be formed: At the center of the mounting structure arrangement 11 of the first spring 1, there is a glue injection hole 12 that penetrates the thickness direction of the first spring 1 (e.g., ...). Figure 4 and Figure 5 (as shown) Correspondingly, at the center of the spring assembly arrangement 21 of the base 2, a glue-applying groove 23 is formed with an inward structure. The diameter of the glue-applying groove 23 on the base 2 is slightly larger than the diameter of the glue injection hole 12 of the first spring 1. In the height direction of the base 2, when the first spring 1 is assembled with the base 2, the glue injection hole 12 of the first spring 1 is basically within the orthogonal projection coverage area of ​​the glue-applying groove 23 (e.g., Figure 5 (as shown) On the spring assembly arrangement position 21 of the base 2, multiple straight adhesive-soaked seams 24 are formed with a concave structure. These adhesive-soaked seams 24 are arranged radially around the adhesive groove 23, such as in a star-shaped or cross-shaped structure, spreading in multiple directions across the entire surface of the spring assembly arrangement position 21. Thus, each adhesive-soaked seam 24 is necessarily connected to the adhesive groove 23, and when the first spring 1 and the base 2 are assembled in place, these adhesive-soaked seams 24 extend to the mating surface between the mounting structure arrangement position 11 and the spring assembly arrangement position 21 (e.g., ...). Figure 2 , Figure 3 , Figure 4 (as shown in Figure 5). With the first spring 1 and the base 2 assembled in place, the glue-permeable seams 24 on the base 2 are connected to the glue injection holes 12 on the first spring 1 via glue distribution grooves 23. Thus, the glue injected through the glue injection holes 12 on the first spring 1 is distributed through the glue distribution grooves 23 on the base 2 into each glue-permeable seam 24, ultimately reaching the mating surface between the aforementioned installation structure arrangement 11 and the aforementioned spring assembly arrangement 21 (e.g., ...). Figure 5 As shown in the figure, the bonding and fixing at the joint surface is achieved to ensure the firmness of the assembly between the first spring 1 and the base 2.

[0037] Based on the assembly structure of the aforementioned glue injection space, the assembly firmness between the first spring 1 and the base 2 can be effectively guaranteed. Therefore, the mounting structure arrangement 11 of the first spring 1 can be loosely fitted with the spring assembly arrangement 21 of the base 2 to achieve assembly, thereby reducing assembly debris. Of course, the loose fit still needs to ensure assembly accuracy; therefore, the following limiting structure is designed: At the spring assembly arrangement position 21 of the base 2, corresponding to both sides of the width direction of the first spring 1, there are limiting protrusions 25 with an outline approximately C formed by an outward convex structure (e.g., Figure 2 and Figure 3 (as shown) Correspondingly, on both sides of the mounting structure arrangement 11 of the first spring 1 in the width direction, there are limiting notches 13 formed in a C-shaped concave structure to fit the corresponding limiting protrusions 25 (e.g., Figure 4 (as shown) When the first spring 1 is assembled into place on the base 2, the limiting notches 13 on the first spring 1 and the corresponding limiting protrusions 25 on the base 2 engage with each other (e.g., Figure 2 (As shown).

[0038] Example 2 The rest of the content of this embodiment is the same as that of embodiment 1, except that: Remove the limiting protrusion on the base; Correspondingly, the limiting notch on the first reed is removed; During the design process, it is sufficient to ensure that the arrangement of the first reed's mounting structure and the arrangement of the reeds on the base have a moderate allowance for loose or tight fit.

[0039] Example 3 The rest of the content of this embodiment is the same as that of embodiment 1, except that: The limiting protrusion on the base is formed in a polygonal structure at the spring assembly arrangement position, which of course needs to be staggered to the glue injection space structure. Correspondingly, a polygonal limiting notch (hole) is formed on the mounting structure of the first reed to match it, so as to achieve limiting fit when assembled.

[0040] Example 4 The rest of the content of this embodiment is the same as that of embodiment 1, except that: The adhesive groove on the base and the adhesive injection hole on the first spring are basically of equal diameter.

[0041] Example 5 The rest of the content of this embodiment is the same as that of embodiment 1, except that: The diameter of the adhesive groove on the base is slightly smaller than the diameter of the adhesive injection hole on the first spring.

[0042] Example 6 The rest of the content of this embodiment is the same as that of embodiment 1, except that: The glue seams on the base are formed with a curved, wave-like structure.

[0043] Example 7 The rest of the content of this embodiment is the same as that of embodiment 1 or 6, except that: The glue-insertion seam on the base is one, passing below the glue injection hole of the first spring.

[0044] Example 8 The rest of the content of this embodiment is the same as that of embodiment 1, except that: The transverse mating section between the first reed and the base is formed in the horizontal direction of the base 2 with a sloped surface structure (or curved surface structure) with a certain angle.

[0045] Of course, in this embodiment, in order to allow the adhesive to flow fully in each adhesive penetration joint, the base needs to be rotated and oscillated appropriately.

[0046] The above embodiments are only used to illustrate the present invention and are not intended to limit it.

[0047] Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications can still be made to the above embodiments, or equivalent substitutions can be made to some of the technical features. For example, to adapt to design needs, the first reed is the stationary reed of an electromagnetic relay, or the electromagnetic relay is other non-push rod structure with the above-mentioned transverse cooperation section; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the present invention.
