Description

Technical Field

[0001] The present application relates to the technical field of relays, and in particular to a relay. Background Art

[0002] Traditional relays typically feature a base for mounting an electromagnetic mechanism, armature, movable and stationary springs. The movable and stationary springs extend from the base for electrical connection to an external circuit. In a normally open relay, when the coil in the electromagnetic mechanism is energized, electromagnetic attraction drives the armature to move, forcing the contacts of the movable and stationary springs into or out of contact, thereby completing the circuit. In traditional relays, during the welding process that connects the movable and stationary springs to the external circuit, heat generated by the welding is easily transferred through the movable and stationary springs to the base, causing deformation and damage to the base. Utility Model Content

[0003] Based on this, it is necessary to provide a relay to address the problem that the heat generated by welding is easily transferred to the base through the moving reed and the static reed, causing deformation and damage to the base.

[0006] a reed, disposed on the base and extending from the base through the slot; and

[0007] An isolating member is sleeved on the reed and located at the slot. The isolating member isolates the portion of the reed located in the slot from the base to reduce the risk of deformation of the base due to heat conducted by the reed.

[0008] The relay is provided with an isolator that fits over the reed. When the reed is mounted on the base, the isolator isolates the reed from the base. Therefore, when welding the relay to electrically connect the portion of the reed outside the base to an external circuit, the heat generated by the welding is transferred through the reed to the isolator. The isolator provides isolation and protection for the base, thereby reducing the risk of deformation of the base due to heat conducted by the reed. This, in turn, avoids problems such as reduced sealing performance and reed displacement caused by base deformation. Furthermore, there is no need to apply heat-resistant material to the entire base, which helps reduce base manufacturing costs. Furthermore, the isolator prevents direct contact between the base and the reed, which could generate scraping that could affect the reed's performance.

[0016] In one embodiment, the base is made of polybutylene terephthalate, and the spacer is made of polyhexamethylene terephthalamide or liquid crystal polymer.

[0017] In one embodiment, the base has two inner walls opposite to each other and located on both sides of the slot, wherein at least a portion of at least one of the inner walls is inclined to the axial direction of the slot, so that the two inner walls form a flared opening toward the outside of the base.

[0018] In one embodiment, the outer peripheral surface of the isolation member abuts against at least a portion of the inner wall of the base that is used to surround and form the slot.

[0037] See Figure 1 and Figure 2 , Figure 1 and Figure 2 The following diagrams respectively illustrate a schematic structural diagram and a cross-sectional diagram of a relay 10 in some embodiments of the present application. The relay 10 provided herein includes, but is not limited to, an electromagnetic relay. In some embodiments, the relay 10 includes a base 11, a movable spring 12, and a stationary spring 13. The base 11 is provided with two spaced slots 1112. The movable spring 12 and the stationary spring 13 are each fixedly mounted on the base 11 and provided with two slots 1112, extending from the base 11 through the slots 1112. The portions of the movable spring 12 and the stationary spring 13 located outside the base 11 are configured to connect to an external circuit, for example, by soldering or any other suitable means to an external circuit board, thereby establishing an electrical connection with the external circuit.

[0038] In some embodiments, the relay 10 may further include an electromagnetic mechanism (not shown) and an operating structure (not shown). The electromagnetic mechanism is disposed on the base 11, and the operating structure is movably disposed on the base 11, for example, rotatably disposed on the base 11. The electromagnetic mechanism may be an electromagnet composed of an iron core and a coil wound around the iron core, and the operating structure includes, but is not limited to, an armature structure. It is understood that when the coil of the electromagnetic mechanism passes through, the electromagnetic mechanism generates a magnetic field that, through electromagnetic force, drives the operating structure to move relative to the base 11. This causes the operating structure to deform a portion of the movable reed 12 toward the side closer to the stationary reed 13 until the movable contact 1211 on the movable reed 12 contacts the stationary contact 131 on the stationary reed 13, thereby connecting the movable and stationary reeds 12 and 13 to an external circuit. In some embodiments, the relay 10 may further include a housing (not shown), which is disposed on the base 11 and covers the electromagnetic mechanism and a portion of the reed. The portion of the reed extending outside the base 11 is exposed to the housing. The housing provides support and protection for the relay 10.

[0039] Combine Figure 2 、 Figure 3 and Figure 4As shown, in some embodiments, the base 11 may include a first mounting portion 111, a second mounting portion 112, and an isolation portion 113. The first mounting portion 111 and the second mounting portion 112 are connected, and the isolation portion 113 is connected between the first mounting portion 111 and the second mounting portion 112. A slot 1112 is provided on the first mounting portion 111, the movable spring 12 and the stationary spring 13 are fixedly mounted on the first mounting portion 111, and the electromagnetic mechanism is mounted on the second mounting portion 112. The active structure is rotatably connected to the base 11 and extends from one side of the isolation portion 113 to the other. Of course, the above description is merely an example of the structure and operating principle of some embodiments of the relay 10, and the component composition and operating mechanism of the relay 10 are not limited to the above description.

[0040] Furthermore, in some embodiments, the relay 10 further includes two isolators, namely a first isolator 14 and a second isolator 15. The first isolator 14 is mounted on the movable reed 12, and the second isolator 15 is mounted on the stationary reed 13. When the movable reed 12 and the stationary reed 13 are fixedly mounted on the base 11, the two isolators are respectively located in the two slots 1112 and respectively isolate the movable reed 12 from the base 11 and the stationary reed 13 from the base 11, thereby reducing the risk of deformation of the base 11 due to heat conducted by the reeds. It is understood that during the assembly process of the relay 10, the first isolator 14 and the second isolator 15 can be respectively mounted on the movable reed 12 and the stationary reed 13, and then the movable reed 12 and the stationary reed 13 can be fixedly mounted on the base 11, so that the portions of the movable reed 12 and the stationary reed 13 that are mounted with the isolators are located in the slots 1112, and the isolators isolate the movable reed 12 from the base 11, and the stationary reed 13 from the base 11.

[0041] In some embodiments, the isolator can reduce the risk of deformation of the base 11 due to heat conducted from the reed by making the isolator material have a higher temperature resistance than that of the base 11. For example, the thermal deformation temperature of the isolator is higher than that of the base 11. In this case, the isolator with a higher temperature resistance, located between the base 11 and the reed, is less likely to deform due to high temperatures, and can provide insulation and protection for the base 11, reducing the probability of deformation of the base 11. Alternatively, the isolator can act as a thermal insulator between the base 11 and the reed to reduce the amount of heat conducted from the reed to the base 11, thereby also reducing the risk of deformation of the base 11. In this case, the isolator can be made of a material with a lower thermal conductivity than the base 11. The isolator can also be made of a material with good temperature resistance and a lower thermal conductivity, effectively reducing the amount of heat conducted from the reed to the base 11 while also making the isolator less likely to deform due to high temperatures. The specific temperature resistance and thermal conductivity of the isolator are not limited and can be designed based on the heat of the reed during welding and the temperature resistance of the base 11.

[0042] In the relay 10 described above, when the portion of the reed located outside the base 11 is electrically connected to an external circuit via welding, the heat generated by the welding is conducted through the reed to the isolator. The isolator can provide isolation and protection for the base 11, thereby reducing the risk of deformation of the base 11 due to heat conducted by the reed. This, in turn, prevents deformation of the base 11, which can lead to a decrease in the sealing performance between the base 11 and the reed, and reed displacement. Furthermore, since the cost of materials with stronger heat resistance is generally higher than that of materials with weaker heat resistance, the relay 10 described above does not need to be provided with heat-resistant material throughout the base 11 or replaced with the entire base 11, which helps reduce the manufacturing cost of the base 11. Furthermore, the isolator can prevent direct contact between the base 11 and the reed, which could affect the performance of the reed. In some embodiments, the axial dimension of the isolator in the slot 1112 can be adapted to the axial dimension of the slot 1112. This effectively isolates the base 11 and the reed, preventing deformation of the base 11 due to high temperatures, while also effectively reducing the consumables of the isolator and reducing the overall component cost of the relay 10.

[0043] It should be noted that, in this application, the description of the isolator being located in the slot 1112 and isolating the base 11 from the reed can be understood as meaning that, due to the provision of the isolator, the portion of the reed located in the slot 1112 is separated from the base 11, thereby preventing heat generated by the reed from being transferred to the base 11. In the extension direction of the reed, the isolator may cover the entire portion of the reed located in the slot 1112, or may cover only the layout area of ​​the portion of the reed located in the slot 1112, as long as the provision of the isolator can separate the portion of the reed located in the slot 1112 from the base 11.

[0044] In some embodiments, each slot 1112 of the base 11 is formed by four inner walls 1111 connected in sequence by the base 11, that is, the slot 1112 is roughly a closed slot structure with openings at both ends, wherein the four inner walls 1111 of one slot 1112 are connected in sequence and arranged circumferentially around the first isolation member 14, and the four inner walls 1111 of another slot 1112 are connected in sequence and arranged circumferentially around the second isolation member 15.

[0045] The specific settings of the material and temperature resistance of the base 11 and the isolator are not limited and can be designed according to the actual temperature resistance requirements, as long as the temperature resistance of the isolator is stronger than that of the base 11 to reduce the impact of deformation of the relay 10 during welding on the performance. In some embodiments, the thermal deformation temperature of the base 11 is greater than or equal to 180°C and less than or equal to 210°C, and the melting point of the base 11 is greater than 230°C, for example, it can be 250°C. The thermal deformation temperature of the isolator is greater than or equal to 250°C and less than or equal to 300°C, and the melting point of the isolator can be greater than or equal to 300°C, for example, it can be 300°C, which can effectively meet the temperature resistance requirements of the relay 10. The material of the base 11 includes but is not limited to any suitable low-cost material such as polybutylene terephthalate (PBT), and the material of the isolation member includes but is not limited to any suitable material with stronger temperature resistance such as polyhexamethylene terephthalamide (PA6T) and liquid crystal polymer (LCP).

[0046] Combine Figure 5 、 Figure 6 and Figure 7 As shown, in some embodiments, the second isolating member 15 includes four sequentially connected sub-isolating plates 151. The four sub-isolating plates 151 together form a hollow frame structure with open ends. When the second isolating member 15 is sleeved on the static spring 13, the four sub-isolating plates 151 can be located on four circumferential sides of the static spring 13, thereby isolating the static spring 13 from the base 11 in all directions and reducing the risk of deformation of the base 11 due to heat conducted by the static spring 13. For example, the outer peripheral surface of the second isolating member 15, i.e., the outer side surfaces of the four sub-isolating plates 151, abuts against at least a portion of the inner wall 1111 of the base 11 that encloses the slot 1112. This not only isolates the static spring 13 from the base 11, but also helps improve the sealing performance between the second isolating member 15 and the base 11. In some embodiments, the second isolating member 15 also includes a tight-fitting portion 152 that is radially retracted relative to the four sub-isolating plates 151. The tight-fitting portion 152 is connected to one end of the four sub-isolating plates 151. The tight-fitting connection between the tight-fitting portion 152 and the static reed plate 13 can enhance the assembly strength between the second isolating member 15 and the static reed plate 13, thereby enhancing the structural reliability and performance stability of the relay 10.

[0047] See Figure 8 and Figure 9As shown, in some embodiments, the first isolating member 14 may also include four sequentially connected sub-isolating plates 151. The four sub-isolating plates 151 can fully isolate the movable spring 12 from the base 11 on all four sides of the movable spring 12 in the circumferential direction. The outer peripheral surface of the first isolating member 14, i.e., the outer side surfaces of the four sub-isolating plates 151, can abut against at least a portion of the inner wall 1111 of the base 11 that is used to enclose the slot 1112. This isolates the movable spring 12 from the base 11 while improving the sealing performance between the base 11 and the first isolating member 14. In some embodiments, the first isolating member 14 may also include a tight-fitting portion 152 connected to one end of the four sub-isolating plates 151 and radially inwardly contracted relative to the sub-isolating plates 151. The tight-fitting connection between the tight-fitting portion 152 and the movable spring 12 improves the connection strength between the first isolating member 14 and the movable spring 12.

[0048] Further, combined with Figure 2 、 Figure 8 and Figure 9 As shown, in some embodiments, the movable spring 12 includes an operating portion 121 and a connecting portion 122. The operating portion 121 is connected to one side of the connecting portion 122 and is provided with a movable contact 1211 facing the static spring 13. The static contact 131 is provided on the side of the static spring 13 facing the movable contact 1211 and corresponds to the position of the movable contact 1211. The connecting portion 122 is partially located within the slot 1112 and partially extends from the base 11 for electrical connection to an external circuit. The operating portion 121 is located outside the slot 1112 and opposite the static spring 13. The operating portion 121 may be flexible and, driven by the operating structure, deform toward the side of the static spring 13 until the movable contact 1211 on the operating portion 121 contacts the static contact 131 on the static spring 13, thereby connecting the movable spring 12 and the static spring 13 to the external circuit. The first isolating member 14 is provided with an escape groove 141 on the side corresponding to the connection portion 122 connecting to the actuating portion 121. The end of the actuating portion 121 connected to the connection portion 122 is located within the escape groove 141. Thus, the first isolating member 14 not only provides isolation between the movable spring 12 and the base 11, but also has a structural design that is well compatible with the structural design of the movable spring 12, without affecting the performance of the movable spring 12.

[0049] Please see again Figure 2 and Figure 8 As shown, in some embodiments, the connecting portion 122 and the acting portion 121 can be a split structure, and a protruding structure 123 is protruded on one side of the connecting portion 122 facing the acting portion 121. There can be multiple protruding structures 123, and the multiple protruding structures 123 are spaced apart on the connecting portion 122. Figure 8The three protruding structures 123 are taken as an example. The protruding structures 123 are provided through the action portion 121 to enhance the connection strength between the action portion 121 and the connection portion 122. In some embodiments, a groove 1113 is provided on the inner wall 1111 of the base 11 corresponding to the slot 1112 for accommodating the movable spring 12. The portion of the protruding structure 123 extending from the action portion 121 facing away from the connection portion 122 is embedded in the groove 1113. The provision of the protruding structures 123 can simultaneously enhance the connection strength between the connection portion 122 and the action portion 121, as well as the connection strength between the movable spring 12 and the first mounting portion 111, thereby improving the structural reliability of the relay 10 without increasing the space occupied by the relay 10. It is understandable that the protruding structures 123 are provided corresponding to the avoidance groove 141 of the first isolation member 14. In some embodiments, a protrusion structure 123 may also be provided on the static spring piece 13 to be embedded in the groove 1113 on the first mounting portion 111 to improve the connection reliability between the static spring piece 13 and the base 11. The contact area between the protrusion structure 123 and the base 11 is small, and the thermal conductivity is limited, which is not easy to cause deformation of the base 11 during the welding process.

[0050] Please see again Figure 2 and Figure 4 As shown, in some embodiments, the base 11 has two inner walls 1111 opposing each other and located on either side of the slot 1112. At least portions of the two inner walls 1111 are inclined to form a flare facing outward from the base 11. When the base 11 is provided with two slots 1112 for the movable spring 12 and the stationary spring 13 to pass through, the base 11 has four inner walls 1111, each of which is opposed to each other and inclined to form two flares. Thus, when the base 11 and the movable spring 12 and the stationary spring 13 are fixedly connected by glue, the flare can increase the adhesion area and adhesion depth between the glue and the base 11, the movable spring 12, and the stationary spring 13, thereby improving the connection reliability and sealing performance between the base 11 and the movable spring 12 and the stationary spring 13, thereby improving the performance reliability of the relay 10. Of course, in other embodiments, only at least a portion of one of the inner walls 1111 may be inclined to the axial direction of the slot 1112, as long as the two inner walls 1111 can form an expansion to increase the glue adhesion area and adhesion depth.

[0051] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
