Description

relay

[0001] This disclosure claims priority to Chinese Patent Application No. 202410954554.9, filed on July 16, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of electronic control device technology, and more specifically, to a relay. Background Technology

[0003] A relay is an electronic control device that has a control system (also known as an input circuit) and a controlled system (also known as an output circuit), and is commonly used in automatic control circuits. Essentially, a relay is an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays a role in automatic adjustment, safety protection, and circuit switching in circuits.

[0004] The relay includes a relay body, a housing for accommodating the relay body, and a connector assembly for connecting to the relay body. The connector assembly includes a connector cover for connecting to an external connector and conductive members for electrically connecting to the coil terminals and / or auxiliary leads of the relay body. The connector cover is connected to the housing, and the external connector is used for electrical connection to an external power source.

[0005] However, when the relay is subjected to a large impact, the connection between the connector cover and the housing in the related technology is not firm, and the connector cover is prone to shaking relative to the housing, which in turn causes the conductive components to loosen from the relay body. Summary of the Invention

[0018] The second shell has a slot, and the portion of the first annular sidewall located away from the first wall and on both sides of the notch is inserted into the slot.

[0019] According to some embodiments of this disclosure, the interior of the second shell is provided with a reinforcing portion, and the reinforcing portion and the inner wall surface of the second shell form the slot.

[0020] According to some embodiments of this disclosure, the relay body is interference-fitted with the first housing.

[0021] According to some embodiments of this disclosure, the mounting portion has a slot, and the connector cover has two insertion portions, which are respectively inserted into the slots of the two mounting portions;

[0022] The slot has a stop wall, and the insertion part has a stop section;

[0023] When the plug is inserted into the slot, the two stop walls are provided with stop sections on opposite sides of the arrangement direction of the two mounting parts, and the orthographic projections of the stop walls and the stop sections on the target plane have overlapping projections; the target plane is perpendicular to the arrangement direction of the two mounting parts.

[0024] According to some embodiments of this disclosure, the connector cover further includes:

[0025] The cover is used to connect to the external connector;

[0026] An extension is connected to the cover and located between the two mounting portions, and inserted into the notch. The conductive member is connected to the extension, and the end of the conductive member is located inside the cover. The insertion portion is integrally formed on both sides of the extension along the arrangement direction of the two mounting portions.

[0027] According to some embodiments of this disclosure, the cover and one of the mounting portions are located on the same side of the extension along the arrangement direction of the two mounting portions, the mounting portion having a limiting protrusion that abuts against the cover.

[0028] According to some embodiments of the present disclosure, the slot has a first opening facing the extension;

[0029] The insertion portion also has an extension section that extends into the slot from the first opening, one end of the extension section being connected to the extension portion and the other end being connected to the stop section.

[0030] According to some embodiments of this disclosure, the slot further includes a side wall, one end of which extends out of the end face of the stop wall along its length, and the portion of the side wall extending out of the end face forms an accommodating space with the end face.

[0031] The connector cover also has two limiting parts, which are respectively connected to the two plug-in parts and are respectively housed in the two receiving spaces and in contact with the end face.

[0032] According to some embodiments of this disclosure, one of the inner surface of the slot and the outer surface of the insertion portion is provided with a second protrusion, and the second protrusion is interference-fitted with the other.

[0035] The external connector is connected to the connector cover along a mating direction, which is perpendicular to the mounting direction.

[0036] An embodiment of the above application has at least the following advantages or beneficial effects:

[0037] In this embodiment of the relay, after the relay body is installed inside the housing, it compresses the housing wall, causing the housing to expand outward and generate an external support force. This external support force causes the two mounting portions on both sides of the notch to tend to move away from each other. The connector cover is connected to the two mounting portions and is used to clamp the two mounting portions using the external support force. Therefore, under the action of the external support force, the connector cover can firmly clamp the two mounting portions, significantly improving the stability of the connection between the connector cover and the housing, and preventing the electrical connection between the conductive components and the relay body from being affected by the connector cover's wobbling relative to the housing. Furthermore, since the connector cover and the two mounting portions are connected separately, the connector assembly can be installed in the housing at different angles, thereby adapting to external connectors in different installation environments and improving the relay's versatility.

[0038] Furthermore, the second shell is interference-fitted with the first protrusion of the first shell, which allows the second shell to tighten the first annular sidewall, reducing the magnitude of the external support force. This prevents the connector cover from being subjected to excessive external support force, thus avoiding the problem of the connector cover breaking due to excessive external support force.

[0039] Furthermore, by providing a limiting protrusion on the mounting part, the stability of the connector cover can be maintained, further preventing the connector cover from shaking relative to the housing.

[0040] Furthermore, by inserting the first annular sidewall of the first shell into the slot of the second shell, the strength of the shell wall near the notch in the first annular sidewall can be improved, preventing the shell wall near the notch in the first annular sidewall from being recessed inward and affecting the assembly of the connector assembly and the shell.

[0054] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0055] It is understood that the terms "comprising" and "having," and any variations thereof, used in the embodiments of this disclosure, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to such processes, methods, products, or apparatus.

[0056] As shown in Figures 1 and 2, the relay of this embodiment includes a relay body 20, a housing 10 for housing the relay body 20, and a connector assembly 30 for connecting to the relay body 20. The connector assembly 30 is capable of connecting to an external connector (not shown in the figures).

[0057] The relay body 20 may include a contact portion 21 and a magnetic circuit portion 22. The contact portion 21 has a contact assembly, and the magnetic circuit portion 22 is used to drive the contact assembly to close or open.

[0058] The housing 10 includes a second housing 11 and a first housing 12 made of insulating material, which are connected to form a cavity for accommodating the relay body 20. During assembly, the relay body 20 is first inserted into the first housing 12, and then the second housing 11 is connected to the first housing 12.

[0059] As an example, the relay body 20 is interference-fitted with the first housing 12, which improves the stability between the relay body 20 and the first housing 12 and prevents the relay body 20 from shaking relative to the housing 10.

[0060] In one embodiment, the first housing 12 surrounds the magnetic circuit portion 22 of the relay body 20, and the second housing 11 surrounds the contact portion 21 of the relay body 20, but is not limited thereto.

[0061] For example, in another embodiment, the first shell 12 surrounds the entire magnetic circuit portion 22 and the lower half of the contact portion 21, and the second shell 11 surrounds the upper half of the contact portion 21; in yet another embodiment, the first shell 12 surrounds the lower half of the magnetic circuit portion 22, and the second shell 11 surrounds the entire contact portion 21 and the upper half of the magnetic circuit portion 22.

[0062] As shown in Figure 1, the housing 10 also includes mounting feet 15 for mounting the relay to an external device (not shown). Mounting feet 15 can be located in the second housing 11 or the first housing 12. For example, the outer wall surface of the second housing 11 may have mounting feet 15, but this is not a limitation.

[0063] As shown in Figure 2, the first shell 12 includes a first annular sidewall 122 and a first wall 121. One end of the first annular sidewall 122 is connected to the first wall 121, and the other end of the first annular sidewall 122 is connected to the second shell 11.

[0064] As an example, the first annular sidewall 122 and the first wall 121 are an integral structure.

[0065] As shown in Figure 3, the second shell 11 includes a second annular sidewall 112 and a second wall 111. One end of the second annular sidewall 112 is connected to the second wall 111, and the other end of the second annular sidewall 112 is connected to the other end of the first annular sidewall 122. Mounting feet 15 can be disposed on the outer wall surface of the second annular sidewall 112.

[0066] As an example, the second annular sidewall 112 and the second wall 111 are an integral structure.

[0067] As shown in Figures 2 and 3, the second shell 11 and the first shell 12 can be connected by a snap-fit ​​method. For example, the first annular sidewall 122 of the first shell 12 has multiple snap-fit ​​blocks 1221, and the second annular sidewall 112 of the second shell 11 has multiple snap-fit ​​holes 1121, with the multiple snap-fit ​​blocks 1221 respectively snapping into the multiple snap-fit ​​holes 1121.

[0068] It is understood that the rings formed by the first annular sidewall 122 and the second annular sidewall 112 can be circular, rectangular or other shapes, and this disclosure does not make any special limitation in this regard.

[0069] As shown in Figure 2, the connector assembly 30 includes a connector cover 31, a conductive member 32, and a fixing member 33. The connector cover 31 and the fixing member 33 are made of insulating material, and the conductive member 32 is made of conductive material. The connector cover 31, the conductive member 32, and the fixing member 33 can be integrally injection molded into a single part.

[0070] The fixing member 33 is connected to the relay body 20. One end of the conductive member 32 is connected to the fixing member 33, and the other end of the conductive member 32 is connected to the connector cover 31 and located inside the connector cover 31, serving as a lead-out terminal of the relay body 20. The connector cover 31 can be connected to an external connector by plugging it in. When the external connector is plugged into the connector cover 31, the external connector is electrically connected to the lead-out terminal.

[0071] In one embodiment, as shown in FIG1, the second housing 11 is connected to the first housing 12 along an installation direction D1, and the external connector is connected to the connector cover 31 along an insertion direction D2. The insertion direction D2 is perpendicular to the installation direction D1. The insertion direction D2 and the installation direction D1 do not interfere with each other, thereby avoiding assembly interference problems between the connector assembly 30 and the housing 10.

[0072] Please refer to Figure 2. The relay body 20 may have two coil leads 23 and two auxiliary contact leads 24. Correspondingly, the conductive member 32 includes four conductive strips 321. One end of each of the four conductive strips 321 is electrically connected to the two coil leads 23 and the two auxiliary contact leads 24, respectively. The other end of each of the four conductive strips 321 is located inside the connector cover 31 for connection with an external connector.

[0073] As shown in Figures 2, 4 and 5, the housing 10 includes two spaced-apart mounting portions 13 and a notch 14 located between the two mounting portions 13.

[0074] In this embodiment of the present disclosure, the outer wall surface of the first annular sidewall 122 of the first shell 12 is integrally formed with a mounting portion 13. The portion of the first annular sidewall 122 of the first shell 12 located between the two mounting portions 13 has a notch 14, which penetrates the inner wall surface and the outer wall surface of the first annular sidewall 122 of the first shell 12. The notch 14 is recessed from the edge of the first annular sidewall 122 away from the first wall 121 toward the first wall 121.

[0075] Of course, in other embodiments, the mounting portion 13 and the notch 14 may also be formed in the second shell 11. For example, the outer wall surface of the second annular sidewall 112 of the second shell 11 is integrally formed with two mounting portions 13, and the portion of the second annular sidewall 112 located between the two mounting portions 13 has a notch 14, which is recessed from the edge of the second annular sidewall 112 away from the second wall 111 toward the direction closer to the second wall 111.

[0076] The following description will take the example of the first annular sidewall 122 of the first shell 12 where both the notch 14 and the mounting part 13 are formed.

[0077] The conductive member 32 of the connector assembly 30 passes through the notch 14 and is used to electrically connect the relay body 20 and the external connector. The connector cover 31 is separately connected to the two mounting parts 13 and is used to clamp the two mounting parts 13 by utilizing the external support force formed by the extrusion of the housing 10 by the relay body 20.

[0078] In this embodiment of the relay, after the relay body 20 is installed inside the housing 10, it compresses the housing wall of the housing 10, causing the housing 10 to expand outward and generate an external support force. This external support force causes the two mounting portions 13 on both sides of the notch 14 to tend to move away from each other. The connector cover 31 is connected to the two mounting portions 13 and is used to clamp the two mounting portions 13 using the external support force. Therefore, under the action of the external support force, the connector cover 31 can firmly clamp the two mounting portions 13, significantly improving the stability of the connection between the connector cover 31 and the housing 10, and preventing the electrical connection between the conductive member 32 and the relay body 20 from being affected by the shaking of the connector cover 31 relative to the housing 10. Furthermore, since the connector cover 31 and the two mounting portions 13 are connected separately, the connector assembly 30 can be installed in the housing 10 at different angles, thereby adapting to external connectors in different installation environments and improving the versatility of the relay.

[0079] As shown in Figures 4 and 5, the outer wall surface of the first annular sidewall 122 is provided with a plurality of first protrusions 123. The plurality of first protrusions 123 are arranged on both sides of the notch 14 along the circumference of the first annular sidewall 122. The second shell 11 is interference-fitted with the first protrusions 123.

[0080] In this embodiment of the present disclosure, the second shell 11 and the first protrusion 123 of the first shell 12 are interference-fitted, so that the second shell 11 can tighten the first annular sidewall 122, reduce the magnitude of the external support force, and thus prevent the connector cover 31 from being subjected to excessive external support force, thereby avoiding the problem of the connector cover 31 breaking due to excessive external support force.

[0081] In one embodiment, the outer wall surface of the first annular sidewall 122 is provided with two first protrusions 123, which are located on both sides of the notch 14 along the circumference of the first annular sidewall 122.

[0082] In this disclosure, the shape of the first protrusion 123 is not particularly limited. For example, the first protrusion 123 can be elongated, hemispherical, wedge-shaped, etc.

[0083] As shown in Figures 4 and 5, the mounting portion 13 has a slot 131. In one embodiment, the extending direction of the slot 131 is parallel to the mounting direction D1 of the second housing 11 and the first housing 12.

[0084] As shown in Figure 6, the connector cover 31 includes a cover body 312, an extension 313, and two insertion portions 311. The cover body 312 has a receiving groove 3121 for accommodating at least a portion of an external connector. The extension 313 is connected to the cover body 312 and is inserted into a notch 14 of the housing 10, located between the two mounting portions 13. A conductive member 32 is connected to the extension 313, and the end of the conductive member 32 is located within the receiving groove 3121 of the cover body 312; the insertion portions 311 are integrally formed on both sides of the extension 313 along the arrangement direction of the two mounting portions 13. The two insertion portions 311 are respectively inserted into the slots 131 of the two mounting portions 13. The insertion direction of the corresponding insertion portion 311 and the slot 131 is parallel to the mounting direction D1 of the second housing 11 and the first housing 12.

[0085] In this embodiment of the present disclosure, the connector cover 31 and the mounting part 13 are connected by a plug-in method, which not only ensures the stability of the connection between the connector cover 31 and the mounting part 13, but also improves the assembly efficiency.

[0086] As shown in Figures 4, 6, 7, and 8, the slot 131 has a stop wall 132, and the insertion part 311 has a stop section 3111. The two stop walls 132 are provided with stop sections 3111 on opposite sides of the arrangement direction of the two mounting parts 13. When the insertion part 311 is inserted into the slot 131, the orthographic projections of the stop wall 132 and the stop section 3111 on the target plane overlap; the target plane is perpendicular to the arrangement direction of the two mounting parts 13.

[0087] In this embodiment of the present disclosure, when the two plug-in portions 311 are respectively inserted into the slots 131 of the two mounting portions 13, the two stop segments 3111 can respectively squeeze the corresponding stop walls 132, so that the two mounting portions 13 come together.

[0088] As shown in Figure 8, the cover 312 and one of the mounting portions 13 are located on the same side of the extension 313 along the arrangement direction of the two mounting portions 13. The mounting portion 13 has a limiting protrusion 133 that abuts against the cover 312. By providing the limiting protrusion 133 on the mounting portion 13, the stability of the connector cover 31 can be maintained, further preventing the connector cover 31 from shaking relative to the housing 10.

[0089] As shown in Figures 4 and 8, the slot 131 has a first opening 134 facing the extension 313; the insertion portion 311 also has an extension 3112 extending into the slot 131 from the first opening 134, one end of the extension 3112 being connected to the extension 313, and the other end being connected to the stop portion 3111. In other words, the cross-sectional shape of the insertion portion 311 is approximately L-shaped, but not limited thereto. For example, the cross-sectional shape of the insertion portion 311 can also be dovetail-shaped, T-shaped, or other shapes capable of applying an inward converging force to the two mounting portions 13.

[0090] As shown in Figure 4, the slot 131 also includes a side wall 135, which together with the stop wall 132 forms the slot 131. One end of the side wall 135 extends out of the end face 1321 of the stop wall 132 along its length, and the portion of the side wall 135 extending out of the end face 1321 together with the end face 1321 forms an accommodating space 136.

[0091] As shown in Figures 1 and 6, the connector cover 31 also has two limiting portions 314, which are respectively connected to two insertion portions 311 and housed within two receiving spaces 136, and contact the end face 1321. When the insertion portion 311 is inserted into the slot 131, as the insertion portion 311 is inserted deeper, the limiting portion 314 gradually approaches the end face 1321 of the stop wall 132. When the limiting portion 314 contacts the end face 1321, it indicates that the insertion portion 311 has been inserted into place. In addition, the limiting portion 314 being housed within the receiving space 136 can improve the compactness of the insertion structure and enhance the stability of the connection between the insertion portion 311 and the slot 131.

[0092] As shown in Figures 8 and 9, a second protrusion 137 is provided on one of the inner surface of the slot 131 and the outer surface of the insertion part 311, and the second protrusion 137 is interference-fitted with the other. By providing the second protrusion 137, the firmness of the connection between the insertion part 311 and the mounting part 13 can be improved.

[0093] For example, in one embodiment, the inner surface of the slot 131 is provided with a second protrusion 137, and the second protrusion 137 is in an interference fit with the insertion part 311; in another embodiment, the outer surface of the insertion part 311 is provided with a second protrusion 137, and the second protrusion 137 is in an interference fit with the slot 131.

[0094] In this disclosure, the shape of the second protrusion 137 is not particularly limited. For example, the second protrusion 137 can be elongated, hemispherical, etc.

[0095] As shown in Figure 1, the receiving groove 3121 of the connector cover 31 has a second opening 3122 whose opening direction is parallel to the arrangement direction of the two mounting parts 13. The external connector can be inserted into the cover 312 through the second opening 3122. In other words, the insertion direction of the external connector and the connector cover 31 is parallel to the arrangement direction of the two mounting parts 13. Thus, when inserting or removing the external connector, the stability of the connection between the connector cover 31 and the two mounting parts 13 will not be affected.

[0096] As shown in Figures 3, 10, and 11, the second shell 11 has a slot 114. The portion of the first annular sidewall 122 located away from the first wall 121 and on both sides of the notch 14 is inserted into the slot 114. By inserting the first annular sidewall 122 of the first shell 12 into the slot 114 of the second shell 11, the strength of the shell wall near the notch 14 in the first annular sidewall 122 can be improved, preventing the shell wall near the notch 14 of the first annular sidewall 122 from being recessed inward and affecting the assembly of the connector assembly 30 and the shell 10.

[0097] As shown in Figure 3, in one embodiment, the interior of the second shell 11 is provided with a reinforcing part 113, and a groove 114 is formed between the reinforcing part 113 and the inner wall surface of the second annular sidewall 112 of the second shell 11.

[0098] Of course, in other embodiments, the second annular sidewall 112 is thicker, and the slot 114 can also be formed in the second annular sidewall 112 of the second shell 11.

[0099] In summary, the relays of the present disclosure embodiments have at least the following advantages and beneficial effects:

[0100] In this embodiment of the relay, after the relay body 20 is installed inside the housing 10, it compresses the housing wall of the housing 10, causing the housing 10 to expand outward and generate an external support force. This external support force causes the two mounting portions 13 on both sides of the notch 14 to tend to move away from each other. The connector cover 31 is connected to the two mounting portions 13 and is used to clamp the two mounting portions 13 using the external support force. Therefore, under the action of the external support force, the connector cover 31 can firmly clamp the two mounting portions 13, significantly improving the stability of the connection between the connector cover 31 and the housing 10, and preventing the electrical connection between the conductive member 32 and the relay body 20 from being affected by the shaking of the connector cover 31 relative to the housing 10. Furthermore, since the connector cover 31 and the two mounting portions 13 are connected separately, the connector assembly 30 can be installed in the housing 10 at different angles, thereby adapting to external connectors in different installation environments and improving the versatility of the relay.

[0101] Furthermore, the second shell 11 is interference-fitted with the first protrusion 123 of the first shell 12, so that the second shell 11 can tighten the first annular sidewall 122, reducing the magnitude of the external support force, thereby preventing the connector cover 31 from being subjected to excessive external support force and avoiding the problem of the connector cover 31 breaking due to excessive external support force.

[0102] Furthermore, by providing a limiting protrusion 133 on the mounting portion 13, the stability of the connector cover 31 can be maintained, further preventing the connector cover 31 from shaking relative to the housing 10.

[0103] Furthermore, by inserting the first annular sidewall 122 of the first shell 12 into the slot 114 of the second shell 11, the strength of the shell wall near the notch 14 in the first annular sidewall 122 can be improved, and the shell wall near the notch 14 in the first annular sidewall 122 can be prevented from being recessed inward, thus affecting the assembly of the connector assembly 30 and the shell 10.
