Description

Technical Field

[0001] This application relates to the field of relay technology, specifically to a relay. Background Technology

[0002] Relays need to possess good stability and high sensitivity, especially industrial relays, which are required to meet a starting voltage range of 50% to 70%. However, in actual assembly, due to the insertion and installation of conductive components such as the moving spring bracket and stationary spring, there is a 0.1mm to 0.2mm insertion variation, meaning that the mechanical parameters of the relay product, such as contact gap and overtravel, are inconsistent. Therefore, after assembly, the relay cannot guarantee that the starting voltage falls within the 50% to 70% range. Utility Model Content

[0003] The purpose of this application is to provide a relay that addresses the problem of large misalignment in the insertion of conductive components in a relay.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] Some embodiments of this application provide a relay, including a base and a conductive element. The base has a positioning groove, and the main body of the conductive element is inserted into the positioning groove. At the main body of the conductive element, the positioning groove covers at least two sides supporting the conductive element.

[0006] In some embodiments, the positioning groove includes a first positioning groove. The base includes a main body and a first insertion part, the first insertion part being connected to one side of the main body along a first direction, and the first positioning groove being disposed on the first insertion part and extending along the first direction.

[0007] In some embodiments, the first insertion portion has a conductive opening along the second direction, and the conductive opening is connected to the first positioning groove, wherein the second direction is perpendicular to the first direction. Specifically, on the side where the first positioning groove has the conductive opening along the second direction, the conductive opening is located in the middle region of the first insertion portion.

[0008] In some embodiments, the main body is provided with an insertion opening along the first direction, the insertion opening is connected to the first positioning groove, and the end of the first insertion part away from the main body is a closed structure.

[0009] In some embodiments, along the second direction, the first insertion portion is provided with a first positioning portion facing the inner wall of the first positioning groove. The first positioning portion is a protruding structure arranged along the second direction, and the first positioning portion abuts against the conductive element. One side of the conductive element along the second direction is used to contact and connect the movable spring, and the second direction is perpendicular to the first direction.

[0010] In some embodiments, the first positioning part is a rib support structure.

[0011] In some embodiments, along the second direction, the two opposing inner walls of the first insertion portion are provided with a plurality of first positioning portions.

[0012] In some embodiments, the conductive element includes a stationary spring, which includes a stationary spring body and stationary spring leads. The stationary spring body is at least partially inserted into a first positioning groove along a first direction, and the stationary spring leads are connected to the stationary spring body.

[0013] In some embodiments, the positioning groove further includes a second positioning groove. The base also includes a second insertion portion, which is connected to the first insertion portion on the same side of the main body along a first direction. A portion of the second positioning groove extends along the first direction and is disposed on the second insertion portion, and another portion of the second positioning groove extends along a third direction and is disposed on the main body for inserting and mounting conductive components, wherein the first direction and the third direction are perpendicular to each other.

[0014] In some embodiments, the conductive element includes a movable spring bracket, which includes a movable spring body and movable spring pins. The adjacent two sides of the movable spring body are inserted and installed in a second positioning groove, and the movable spring pins are connected to the movable spring body.

[0015] In some embodiments, a second positioning part is provided at least on the inner wall of the main body facing the second positioning groove along the second direction. The second positioning part is a protruding structure provided along the second direction, and the second positioning part abuts against the main body of the moving spring.

[0016] Thus, in this embodiment, by providing a positioning groove on the base of the relay, and ensuring that at least two sides of the main body of the conductive component inserted into the positioning groove are covered by the positioning groove, such as adjacent or opposite side edges being covered and supported by the inner wall of the positioning groove, or three, four, or even more parts being covered and supported by the inner wall of the positioning groove, a larger contact support area is provided between the conductive component and the supporting positioning structure on the base. This helps reduce the insertion dispersion of the conductive component during the insertion and installation process, thereby improving the consistency of mechanical parameters such as contact gap and overtravel during the production and assembly of the relay product, and thus improving the stability and sensitivity of the relay product. As a result, after assembly, the relay can meet the requirement that the starting voltage falls within the range of 50% to 70%. Attached Figure Description

[0032] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application.

[0034] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0035] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0037] A relay is an electronic control device widely used in automatic control circuits to switch circuits on and off. For example, in a relay, by controlling the signal voltage applied to the electromagnetic coil, the armature is controlled to perform a corresponding action, thereby causing the moving spring to contact the stationary spring to either connect or disconnect, thus controlling the circuit's on or off state.

[0038] The following is combined with Figures 1 to 9 The relay provided in this application is described in order to at least solve the problem of large insertion variations of conductive components in the relay.

[0039] like Figure 1 As shown, Figure 1 This is a schematic diagram of the internal three-dimensional structure of a relay provided in an embodiment of this application. The relay 100 includes a base 10 and a conductive element 20. (In conjunction with...) Figure 2 , Figure 2 for Figure 1 The diagram illustrates a three-dimensional structure of the base. The base 10 has a positioning groove 12. The main body of the conductive element 20 is inserted into the positioning groove 12, and the positioning groove 12 covers at least two sides of the main body of the conductive element 20. For example, the conductive element 20 may include a fixedly connected support body and support pins. The support body (i.e., the main body of the conductive element 20) is inserted into the positioning groove 12 to improve the stability of the conductive element 20's insertion and installation through the insertion structure where at least two sides are covered by the positioning groove 12. The support body is used to contact and connect a movable spring, and the conductive element 20 is connected to an external circuit through the support pins.

[0040] For example, such as Figure 1 As shown, the conductive element 20 includes at least one of a stationary spring 21 and a movable spring support 22. When the conductive element 20 is the movable spring support 22, its support body contacts and is fixedly connected to the movable spring 30, serving as a positioning support for the movable spring 30. When the conductive element 20 is the stationary spring 21, in the open circuit state, the stationary spring 21 and the movable spring 30 are spaced apart to keep the circuit open, or the stationary spring 21 and the movable spring 30 are in contact to keep the circuit conductive.

[0041] Based on this, in this embodiment, a positioning groove 12 is provided on the base 10 of the relay 100, and the main body of the conductive component 20, which is inserted and installed in the positioning groove 12, is covered by the positioning groove 12 on at least two sides. For example, adjacent or opposite side edges are covered and supported by the inner wall of the positioning groove 12, or three, four, or even more parts are covered and supported by the inner wall of the positioning groove 12. In this way, by providing a larger contact support area between the conductive component 20 and the supporting positioning structure on the base 10, it is beneficial to reduce the insertion misalignment of the conductive component 20 during the insertion and installation process, thereby improving the consistency of mechanical parameters such as contact gap and overtravel during the production and assembly of the relay product, and thus improving the stability and sensitivity of the relay product. As a result, after assembly, the relay can meet the requirement that the starting voltage falls within the range of 50% to 70%.

[0042] For example, the positioning groove 12 has various structures for inserting and installing conductive components such as the stationary spring 21 and the moving spring bracket 22.

[0043] like Figure 3 and Figure 4 As shown, Figure 3 for Figure 1 A front view of the relay 100 shown. Figure 4 It is along Figure 3 A cross-sectional view along line AA in the middle.

[0044] In some embodiments, refer to Figure 2 and Figure 5 , Figure 5 for Figure 4 A partial enlarged view at point B. The positioning groove 12 may include a first positioning groove 121. The base 10 includes a main body 11 and a first insertion part 13. The first insertion part 13 is connected to one side of the main body 11 along a first direction (such as the Z direction). The first positioning groove 121 is disposed on the first insertion part 13 and extends along the Z direction. This allows the first positioning groove 121 to be used for inserting and installing conductive components 20 such as stationary spring 21 or moving spring bracket 22 along the Z direction. That is, at least two opposite edges of the conductive component 20 are inserted and installed in the first positioning groove 121 to support and fix the conductive component 20. The first insertion part 13 and the main body 11 may be integrally formed components.

[0045] In addition, such as Figure 2 and Figure 6 As shown, Figure 6 for Figure 4A partial enlarged view at point C. The positioning groove 12 also includes a second positioning groove 122. The base 10 also includes a second insertion part 14, which is connected to the first insertion part 13 along the Z direction on the same side of the main body 11, and the main body 11 is connected to the second insertion part 14. A portion of the second positioning groove 122 is located in the second insertion part 14, and the other portion is located in the base 10, for inserting and mounting conductive components 20 such as the stationary spring 21 or the moving spring bracket 22. Figure 1 (As shown). The second insertion part 14 and the main body part 11 can be integrally formed components.

[0046] Taking the Z direction as the vertical direction as an example, a portion of the second positioning groove 122 located at the second insertion part 14 extends in the vertical direction, while another portion of the second positioning groove 122 located on the base 10 extends in the front-back direction (such as the X direction). Correspondingly, the opening direction of the portion of the second positioning groove 122 located at the second insertion part 14 faces forward or backward, such as opening towards the first insertion part 13, while the opening direction of the other portion of the second positioning groove 122 located on the base 10 faces upward, thus forming a second positioning groove 122 that can be roughly viewed as an "L" shape.

[0047] Thus, by providing an L-shaped second positioning groove 122 at the main body 11 and the second insertion part 14, the main body 11 and the second insertion part 14 can simultaneously support two adjacent edges of the conductive component 20, such as the stationary spring 21 or the moving spring bracket 22, thereby improving the stability of the inserted conductive component 20.

[0048] Furthermore, conductive components 20, such as stationary spring 21 or moving spring bracket 22, are installed via interference fit at the first positioning groove 121. And / or, conductive components 20, such as stationary spring 21 or moving spring bracket 22, are installed via interference fit at the second positioning groove 122. This increases the contact area during assembly, reducing misalignment during insertion of the conductive components 20, such as stationary spring 21 and moving spring bracket 22.

[0049] It is understood that, in the embodiments of this application, the first positioning groove 121 can be used to insert and install the stationary spring 21 or the moving spring bracket 22. Correspondingly, the second positioning groove 122 can be used to insert and install the moving spring bracket 22 or the stationary spring 21. The choice can be flexible according to actual needs and the shape of the spatial components, and is not limited thereto.

[0050] In some embodiments, such as Figure 1 As shown, the conductive element 20 includes a stationary spring 21. (Refer to...) Figure 7 and Figure 8 As shown, Figure 7 for Figure 1 A top view of the relay 100 shown. Figure 8 It is along Figure 7 A cross-sectional view of the DD line. The stationary spring 21 includes a stationary spring body 211 and a stationary spring pin 212. The stationary spring body 211 is one of the main parts of the conductive element 20. The stationary spring body 211 is at least partially inserted into the first positioning groove 121 along the Z direction for support and fixation towards the inner wall of the first positioning groove 121 via the first insertion part 13. The stationary spring pin 212 is connected to the stationary spring body 211 for connection to a circuit via a wire or circuit board.

[0051] For example, taking the Z direction as the vertical direction and the main body 11 located below the first insertion part 13 as an example, by opening a first positioning groove 121 along the Z direction at the first insertion part 13, the static spring body 211 can be inserted and installed in the first positioning groove 121 from top to bottom or from bottom to top.

[0052] Taking the example of the stationary spring body 211 being inserted into the first positioning groove 121 from top to bottom, the main body 11 is provided with a pin hole corresponding to the first positioning groove 121, so that the end of the stationary spring pin 212 away from the stationary spring body 211 is inserted from top to bottom through the pin hole at the bottom of the main body 11.

[0053] Or, such as Figure 5 and Figure 8 As shown, along the Z direction, the main body 11 is provided with a plug-in opening 151, which is connected to the first positioning groove 121, and the end of the first plug-in part 13 away from the main body 11 is a closed structure.

[0054] Thus, during the process of inserting and installing conductive components 20 such as the stationary spring 21 into the first positioning groove 121, the end of the stationary spring body 211 away from the stationary spring pin 212 can be inserted into the first positioning groove 121 from bottom to top through the insertion opening 151, so that the three or four sides of the stationary spring body 211 are in contact with the inner wall of the first insertion part 13 for positioning, which helps to reduce the insertion misalignment of conductive components 20 such as the stationary spring 21.

[0055] In some embodiments, such as Figure 2 and Figure 5 As shown, the first insertion portion 13 has a conductive opening 152 along a second direction (such as the Y direction), and the conductive opening 152 is connected to the first positioning groove 121. This second direction is perpendicular to the first direction. Taking the Z direction as an example (vertical direction), the X direction (or a third direction) can be a front-back direction, and the Y direction is a left-right direction. This can be achieved if both the second and first directions are straight lines. Specifically, on the side of the first positioning groove 121 where the conductive opening 152 is located along the Y direction, the conductive opening 152 is situated in the middle region of the first insertion portion 13.

[0056] Taking the insertion and installation of the stationary spring 21 in the first positioning groove 121 as an example, the central region can be the central region of the first insertion part 13 along the vertical direction, so as to at least support and cover the upper edge of the stationary spring 21. The central region can also be the central region of the first insertion part 13 along the front-back direction, that is, both the front and back edges of the stationary spring 21 located in the first positioning groove 121 are supported and covered.

[0057] Thus, along the Z direction, the stationary spring body 211 can be inserted into the first positioning groove 121 from top to bottom or from bottom to top. Through the conductive opening 152 that is connected to the first positioning groove 121, a portion of the stationary spring 21 located in the first positioning groove 121 is exposed through the conductive opening 152 for contact connection with the moving spring.

[0058] Based on this, by setting the upper end of the first positioning groove 121 to be a closed structure and the lower end of the first positioning groove 121 to have an insertion opening 151, after the stationary spring body 211 is inserted into the first positioning groove 121 from bottom to top, the upper end of the stationary spring body 211 is supported and positioned by the upper closed structure, and the lower end of the stationary spring body 211 can be supported and positioned by the inner wall of the main body 11 with the insertion opening 151. Since the conductive opening 152 of the first insertion part 13 is located near the middle area on the side with the conductive opening 152, the front and rear sides of the first positioning groove 121 can also support and position the stationary spring body 211. Moreover, the side of the first insertion part 13 without the conductive opening 152 along the Y direction is also a closed structure, thereby forming a better covering and supporting effect on the inserted stationary spring body 211.

[0059] Thus, during the process of inserting and installing the stationary spring 21 from bottom to top within the first positioning groove 121, the metal stationary spring body 211 will come into contact with the inner wall of the first insertion portion 13, generating scraping. Since the first positioning groove 121 connects only to the assembly space within the main body 11 through the conductive opening 152, the aforementioned closed structure of the first positioning groove 121 prevents or minimizes the entry of scraping generated during assembly into the assembly space. This avoids scraping contaminating the contact points of the stationary spring 21 and the moving spring 30, thus preventing any impact on the contact conductivity between them.

[0060] In some embodiments, such as Figure 5 As shown, along the Y direction, the first insertion part 13 is provided with a first positioning part 153 facing the inner wall of the first positioning groove 121. The first positioning part 153 is a protruding structure provided along the Y direction, and the first positioning part 153 and the conductive parts 20 such as the stationary spring 21 (see reference) Figure 1 (arrival)

[0061] By providing a first positioning part 153 with a protruding structure on the inner wall of the first insertion part 13, the stationary spring body 211 inserted into the first positioning groove 121 is interference-fitted with the first insertion part 13. This reduces the insertion misalignment of the stationary spring 21 and the contact scraping area between the stationary spring body 211 and the inner wall of the first insertion part 13.

[0062] For example, such as Figure 5 As shown, along the Y direction, the two opposite inner walls of the first insertion part 13 are provided with a plurality of first positioning parts 153.

[0063] Thus, within the first positioning groove 121, the opposite sides of the stationary spring body 211 along the Y direction are both interference-fitted with and in contact with the first positioning part 153 of the protruding structure, thereby improving the stability of the insertion and installation of the stationary spring body 211 and reducing insertion misalignment, and making the opposite sides of the stationary spring body 211 along the Y direction spaced apart from the inner wall of the first insertion part 13.

[0064] Furthermore, since the first insertion part 13 is provided with multiple first positioning parts 153 on two opposite inner walls, the stationary spring body 211 mainly contacts multiple first positioning parts 153 during the insertion and assembly process, which greatly reduces the contact area between the stationary spring body 211 and the inner wall of the first insertion part 13 during the insertion and assembly process, thereby helping to reduce the amount of scraping generated during the insertion and assembly process of the stationary spring body 211.

[0065] For example, the first positioning part 153 is a rib support structure. For instance, on the inner wall of the same side of the first insertion part 13, the first positioning parts 153 of multiple rib support structures can extend along the Z direction and be distributed at intervals along the X direction to provide a better support and positioning effect for the static spring body 211.

[0066] Alternatively, on the same inner wall of the first insertion part 13, the first positioning parts 153 of the multiple rib support structures can also be extended along the X direction and distributed at intervals along the Z direction, which can also provide a good support and positioning effect for the static spring body 211.

[0067] In some embodiments, such as Figure 8 As shown, the width of the first positioning groove 121 along the X direction is greater than the width of the stationary spring body 211. Correspondingly, the end of the stationary spring body 211 away from the stationary spring pin 212 along the Z direction has a chamfered or rounded corner structure. This allows the upper end of the stationary spring body 211 to reduce contact wear with the inner wall of the first insertion part 13 during the process of inserting the stationary spring body 211 from bottom to top, through the chamfered and rounded corner structures, thereby reducing or avoiding the generation of scraping debris.

[0068] In some embodiments, the conductive element 20 further includes a movable spring support 22. For example... Figure 9 As shown, Figure 9 It is along Figure 7 A cross-sectional view of the EE line shows that the moving spring bracket 22 includes a moving spring body 221 and moving spring pins 222. The moving spring body 221 is one of the main parts of the conductive element 20. The adjacent sides of the moving spring body 221 are inserted into the second positioning groove 122 to support and fix the moving spring body 221 against the inner wall of the second positioning groove 122 via the second insertion part 14 and the main body part 11. The moving spring pins 222 are connected to the moving spring body 221 for connection to a circuit via wires or a circuit board.

[0069] It should be noted that, in this embodiment, the first positioning groove 121 can be used to install either a stationary spring 21 or a movable spring bracket 22. Correspondingly, the second positioning groove 122 can be used to install either a movable spring bracket 22 or a stationary spring 21. No limitation is made in this regard.

[0070] In this case, the moving spring body 221 of the moving spring bracket 22, which is inserted and installed in the second positioning groove 122, is approximately L-shaped. One edge of the moving spring body 221 is inserted and installed in the second positioning groove 122 of the second insertion part 14, and the adjacent lower edge of the moving spring body 221 is inserted and installed in the second positioning groove 122 of the main body part 11. The two adjacent side walls of the moving spring body 221 are supported and fixed by the joint configuration of the second insertion part 14 and the main body part 11, which helps to reduce the insertion misalignment of the moving spring bracket 22.

[0071] For example, such as Figure 4 and Figure 9 As shown, the main body 11 is provided with a pin through hole 161 along the first direction (i.e., the Z direction). The pin through hole 161 is located at the end of the second positioning groove 122 away from the second insertion part 14, and the pin through hole 161 is connected to the second positioning groove 122 so that the end of the moving spring pin 222 close to the moving spring body 221 is inserted and installed in the pin through hole 161 along the Z direction, so that the end of the moving spring pin 222 away from the moving spring body 221 extends out and is used to connect the circuit.

[0072] In some embodiments, continue to refer to Figure 4 Along the second direction (i.e., the Y direction), at least the main body 11 has a second positioning part 162 facing the inner wall of the second positioning groove 122. The second positioning part 162 is a protruding structure arranged along the Y direction, and the second positioning part 162 and the moving spring body 221 (see reference) Figure 9 (or the moving spring bracket 22 abuts against it.)

[0073] The movable spring bracket 22 is riveted to the movable spring 30 on one side along the Y direction. For example, the protrusion on the movable spring bracket 22 can correspond to the riveting hole on the movable spring 30 to connect the two components. Alternatively, riveting holes can be provided on both the movable spring bracket 22 and the movable spring 30, and the two can be connected by rivets; this is not limited.

[0074] For example, there are multiple second positioning portions 162. Along the Y direction, the multiple second positioning portions 162 can be distributed at intervals on one side or both sides of the inner wall of the second positioning groove 122. The second positioning portions 162 can also be provided on the inner wall of the second insertion portion 14. The second positioning portions 162 can be rib support structures.

[0075] The second positioning part 162 provides stability for the insertion and assembly of the moving spring body 221, thereby reducing insertion misalignment. Furthermore, the second positioning part 162 minimizes contact between the moving spring body 221 and the inner wall of the second positioning groove 122 during insertion and assembly, thus reducing the generation of chips.

[0076] In some embodiments, such as Figure 9 As shown, the width of the second positioning groove 122 along the X direction is greater than the width of the moving spring body 221. Correspondingly, the moving spring body 221 has a chamfered or rounded corner structure at least one end (i.e., the lower end) near the moving spring pin 222 along the Z direction. Alternatively, both ends of the moving spring body 221 along the Z direction can have chamfered or rounded corner structures. This allows the lower end of the moving spring body 221 to reduce contact wear with the second insertion part 14 and the inner wall of the main body 11 through the chamfered and rounded corner structures during the insertion of the moving spring body 221 from top to bottom, thereby reducing or avoiding the generation of scraping debris.

[0077] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.
