Description

Technical Field

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

[0002] A relay is an electronic control device with a control circuit (also known as an input circuit) and a controlled system (also known as an output circuit). It is commonly used in automatic control circuits. A relay is essentially an "automatic switch" that uses a smaller current to control a larger one. Therefore, it plays a role in automatic regulation, safety protection, and circuit switching.

[0003] A relay includes a relay body, a housing for housing 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 a conductive member electrically connected to the coil terminals and / or auxiliary lead terminals of the relay body. The connector cover is connected to the housing, and the external connector is used to electrically connect to an external power source.

[0004] However, when the relay is subjected to a large impact, the connection between the connector cover and the housing in the related art is not firm, and the connector cover is prone to shaking relative to the housing, thereby causing the conductive component and the relay body to loosen.

[0019] According to some embodiments of the present application, the relay body and the first shell are interference fit.

[0020] According to some embodiments of the present application, the mounting portion has a slot, and the connector cover has two plug-in portions, and the two plug-in portions are respectively inserted into the slots of the two mounting portions;

[0021] The slot has a stop wall, and the plug-in portion has a stop section;

[0022] Wherein, when the plug-in part is inserted into the slot, the two stop walls are provided with the stop segments on the side opposite to each other along the arrangement direction of the two mounting parts, and the respective orthographic projections of the stop wall and the stop segment on the target plane have overlapping projections; the target plane is perpendicular to the arrangement direction of the two mounting parts.

[0023] According to some embodiments of the present application, the connector cover further includes:

[0024] a cover body, used for connecting with the external connector;

[0025] The extension part is connected to the cover body, located between the two mounting parts, and inserted into the gap. The conductive component is connected to the extension part, and the end of the conductive component is located in the cover body; the plug-in part is integrally formed on the two side surfaces of the extension part along the arrangement direction of the two mounting parts.

[0026] According to some embodiments of the present application, the cover body and one of the mounting portions are located on the same side of the extension portion along the arrangement direction of the two mounting portions, and the mounting portion has a limiting protrusion, which abuts against the cover body.

[0027] According to some embodiments of the present application, the slot has a first opening that opens toward the extension portion;

[0028] The plug-in portion further comprises an extension section extending from the first opening into the slot, one end of the extension section is connected to the extension portion, and the other end is connected to the stop section.

[0029] According to some embodiments of the present application, the slot further includes a side retaining wall, one end of the side retaining wall extending from an end surface in a longitudinal direction of the stop wall, and a portion of the side retaining wall extending from the end surface and the end surface enclose an accommodation space;

[0030] The connector cover further has two limiting parts, which are respectively connected to the two plug-in parts, respectively accommodated in the two accommodating spaces, and in contact with the end faces.

[0035] One embodiment of the above application has at least the following advantages or beneficial effects:

[0036] In the relay of the embodiment of the present application, after the relay body is installed in the shell, it will squeeze the shell wall of the shell and cause the shell to expand outward to form an external support force, which in turn causes the two mounting parts on both sides of the gap to be subjected to the external support force and have a tendency to move away from each other. The connector cover is connected to the two mounting parts and is used to clamp the two mounting parts using the external support force. It can be seen that under the action of the external support force, the connector cover can firmly clamp the two mounting parts, and the stability of the connection between the connector cover and the shell is significantly improved, avoiding the electrical connection between the conductive member and the relay body being affected by the shaking of the connector cover relative to the shell. In addition, because the connector cover and the two mounting parts adopt a split connection method, the connector assembly can be installed on the shell at different angles, thereby adapting to external connectors in different installation environments, thereby improving the versatility of the relay.

[0037] Furthermore, the second shell is interference fit with the first protrusion of the first shell, so that the second shell plays the role of tightening the first annular side wall, reducing the magnitude of the external support force, and thus preventing the connector cover from being subjected to excessive external support force, thereby avoiding the problem of the connector cover breaking due to excessive external support force.

[0038] Furthermore, by providing a limiting protrusion on the mounting portion, the stability of the connector cover can be maintained, further preventing the connector cover from shaking relative to the housing.

[0039] Furthermore, by inserting the first annular side wall of the first shell into the slot of the second shell, the strength of the shell wall near the notch in the first annular side wall can be improved, thereby preventing the shell wall near the notch of the first annular side wall from sinking inward and affecting the assembly of the connector assembly and the shell.

[0055] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the figures represent like or similar structures, and thus their detailed description will be omitted.

[0056] It is understood that the terms "including" and "having" and any variations thereof in the embodiments of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to the process, method, product, or apparatus.

[0057] like Figure 1 and Figure 2 As shown, the relay of the embodiment of the present application includes a relay body 20, a housing 10 for accommodating the relay body 20, and a connector assembly 30 for connecting to the relay body 20. The connector assembly 30 can be connected to an external connector (not shown in the figure).

[0058] 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.

[0059] The housing 10 includes a second shell 11 and a first shell 12, both made of insulating material. The second shell 11 and the first shell 12 are connected to form a chamber for accommodating the relay body 20. During assembly, the relay body 20 is first installed in the first shell 12, and then the second shell 11 is connected to the first shell 12.

[0060] As an example, the relay body 20 and the first shell 12 are interference-fitted, which can improve the stability between the relay body 20 and the first shell 12 and prevent the relay body 20 from shaking relative to the housing 10 .

[0061] In one embodiment, the first shell 12 surrounds the magnetic circuit portion 22 of the relay body 20 , and the second shell 11 surrounds the contact portion 21 of the relay body 20 , but the present invention is not limited thereto.

[0062] 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.

[0063] like Figure 1 As shown, the housing 10 further includes mounting feet 15 for mounting the relay on an external device (not shown). The mounting feet 15 can be provided on the second housing 11 or the first housing 12. For example, the mounting feet 15 can be provided on the outer wall of the second housing 11, but the present invention is not limited thereto.

[0064] like Figure 2As shown, the first shell 12 includes a first annular side wall 122 and a first wall 121 . One end of the first annular side wall 122 is connected to the first wall 121 , and the other end of the first annular side wall 122 is connected to the second shell 11 .

[0065] As an example, the first annular side wall 122 and the first wall 121 are an integral structure.

[0066] like Figure 3 As shown, the second shell 11 includes a second annular side wall 112 and a second wall 111. One end of the second annular side wall 112 is connected to the second wall 111, and the other end of the second annular side wall 112 is connected to the other end of the first annular side wall 122. The mounting foot 15 can be provided on the outer wall surface of the second annular side wall 112.

[0067] As an example, the second annular side wall 112 and the second wall 111 are an integral structure.

[0068] like Figure 2 and Figure 3 As shown, the second shell 11 and the first shell 12 can be connected by a snap connection. For example, the first annular side wall 122 of the first shell 12 has a plurality of snap blocks 1221, and the second annular side wall 112 of the second shell 11 has a plurality of snap holes 1121, and the plurality of snap blocks 1221 are snapped into the plurality of snap holes 1121 respectively.

[0069] It is understandable that the rings formed by the first annular side wall 122 and the second annular side wall 112 can be circular, rectangular or other shapes, and this application does not specifically limit this.

[0070] like Figure 2 As shown, 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 materials, 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 piece.

[0071] 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. The conductive member 32 is located within the connector cover 31 and serves as a lead terminal for the relay body 20. The connector cover 31 can be plugged into an external connector. When the external connector is plugged into the connector cover 31, the external connector and the lead terminal are electrically connected.

[0072] In one embodiment, if Figure 1As shown, the second shell 11 is connected to the first shell 12 along an installation direction D1, and the external connector is connected to the connector cover 31 along a plugging direction D2. The plugging direction D2 is perpendicular to the installation direction D1. The plugging direction D2 and the installation direction D1 do not interfere with each other, thereby avoiding assembly interference between the connector assembly 30 and the housing 10.

[0073] Please continue reading Figure 2 The relay body 20 may have two coil lead terminals 23 and two auxiliary contact lead terminals 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 lead terminals 23 and the two auxiliary contact lead terminals 24, respectively. The other ends of the four conductive strips 321 are located within the connector cover 31 for connection to an external connector.

[0074] like Figure 2 、 Figure 4 and Figure 5 As shown, the housing 10 includes two spaced apart mounting portions 13 and a gap 14 between the two mounting portions 13 .

[0075] In the embodiment of the present application, a mounting portion 13 is integrally formed on the outer wall of the first annular sidewall 122 of the first shell 12. A notch 14 is formed in the portion of the first annular sidewall 122 of the first shell 12 located between the two mounting portions 13. The notch 14 extends through the inner and outer walls 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.

[0076] Of course, in other embodiments, the mounting portion 13 and the notch 14 may also be formed on the second shell 11. For example, the outer wall surface of the second annular side wall 112 of the second shell 11 is integrally formed with two mounting portions 13, and the portion of the second annular side wall 112 located between the two mounting portions 13 has a notch 14, which is recessed from the edge of the second annular side wall 112 away from the second wall 111 toward the second wall 111.

[0077] Next, an example will be described in which the notch 14 and the mounting portion 13 are both formed on the first annular side wall 122 of the first shell 12 .

[0078] The conductive member 32 of the connector assembly 30 is inserted into 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 portions 13 and is used to clamp the two mounting portions 13 by utilizing the external support force formed by the extrusion of the housing 10 by the relay body 20.

[0079] In the relay of the embodiment of the present application, after the relay body 20 is installed in the housing 10, it will squeeze the shell wall of the housing 10 and cause the housing 10 to expand outward to form an external support force, which in turn causes the two mounting portions 13 on both sides of the notch 14 to be subjected to the external support force and have a tendency 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. It can be seen that under the action of the external support force, the connector cover 31 can firmly clamp the two mounting portions 13, and the stability of the connection between the connector cover 31 and the housing 10 is significantly improved, avoiding the electrical connection between the conductive member 32 and the relay body 20 being affected by the shaking of the connector cover 31 relative to the housing 10. In addition, because the connector cover 31 and the two mounting portions 13 adopt a split connection method, the connector assembly 30 can be installed on the housing 10 at different angles, thereby adapting to external connectors in different installation environments and improving the versatility of the relay.

[0080] like Figure 4 and Figure 5 As shown, the outer wall surface of the first annular side wall 122 is provided with a plurality of first protrusions 123 , which are arranged on both sides of the notch 14 along the circumference of the first annular side wall 122 , and the second shell 11 is interference fit with the first protrusions 123 .

[0081] In the embodiment of the present application, the second shell 11 is interference fit with the first protrusion 123 of the first shell 12, so that the second shell 11 plays the role of tightening the first annular side wall 122, reducing the magnitude of the external support force, and thus preventing 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.

[0082] In one embodiment, two first protrusions 123 are provided on the outer wall surface of the first annular sidewall 122 . The two first protrusions 123 are respectively located on both sides of the notch 14 along the circumferential direction of the first annular sidewall 122 .

[0083] The present application does not particularly limit the shape of the first convex portion 123 . For example, the first convex portion 123 may be in the shape of an elongated strip, a hemispherical shape, a wedge shape, or the like.

[0084] like Figure 4 and Figure 5 As shown, 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 shell 11 and the first shell 12.

[0085] like Figure 6As shown, the connector cover 31 includes a cover body 312, an extension portion 313 and two plug-in portions 311. The cover body 312 has a receiving groove 3121 for accommodating at least part of the external connector. The extension portion 313 is connected to the cover body 312, and is used to be inserted into the notch 14 of the shell 10, and is located between the two mounting portions 13. The conductive member 32 is connected to the extension portion 313, and the end of the conductive member 32 is located in the receiving groove 3121 of the cover body 312; the extension portion 313 is integrally formed with the plug-in portion 311 on both side surfaces along the arrangement direction of the two mounting portions 13. The two plug-in portions 311 are respectively used to be inserted into the slots 131 of the two mounting portions 13. Among them, the plug-in direction of the corresponding plug-in portion 311 and the slot 131 is parallel to the installation direction D1 of the second shell 11 and the first shell 12.

[0086] In the embodiment of the present application, the connector cover 31 and the mounting portion 13 are connected by plugging, which not only ensures the stability of the connection between the connector cover 31 and the mounting portion 13, but also improves the assembly efficiency.

[0087] like Figure 4 、 Figure 6 、 Figure 7 and Figure 8 As shown, the slot 131 has a stop wall 132, and the plug portion 311 has a stop segment 3111. The two stop walls 132 are provided with the stop segments 3111 on opposite sides of the two mounting portions 13 along the arrangement direction. When the plug portion 311 is inserted into the slot 131, the orthographic projections of the stop wall 132 and the stop segment 3111 on a target plane overlap; the target plane is perpendicular to the arrangement direction of the two mounting portions 13.

[0088] In the embodiment of the present application, when the two plug-in portions 311 are respectively inserted into the slots 131 of the two mounting portions 13 , the two stopping sections 3111 can respectively press the corresponding stopping walls 132 , so that the two mounting portions 13 are brought together.

[0089] like Figure 8 As shown, the cover body 312 and one of the mounting portions 13 are located on the same side of the extension portion 313 along the arrangement direction of the two mounting portions 13. The mounting portion 13 has a limiting protrusion 133, which abuts against the cover body 312. The provision of the limiting protrusion 133 on the mounting portion 13 maintains the stability of the connector cover 31, further preventing the connector cover 31 from shaking relative to the housing 10.

[0090] like Figure 4 and Figure 8As shown, the slot 131 has a first opening 134 that opens toward the extension portion 313. The plug portion 311 also has an extension section 3112 that extends from the first opening 134 into the slot 131. One end of the extension section 3112 is connected to the extension portion 313, and the other end is connected to the stop section 3111. In other words, the cross-section of the plug portion 311 is generally L-shaped, but this is not limited to this. For example, the cross-section of the plug portion 311 can also be dovetail-shaped, T-shaped, or other shapes that can exert an inward force on the two mounting portions 13.

[0091] like Figure 4 As shown, the slot 131 further includes a side retaining wall 135, which, together with the stop wall 132, encloses the slot 131. One end of the side retaining wall 135 extends beyond an end surface 1321 in the longitudinal direction of the stop wall 132, and the portion of the side retaining wall 135 extending beyond the end surface 1321 encloses an accommodating space 136 with the end surface 1321.

[0092] like Figure 1 and Figure 6 As shown, the connector cover 31 also has two stoppers 314. These stoppers 314 are respectively connected to the two plug-in sections 311, housed in the two receiving spaces 136, and in contact with the end surfaces 1321. As the plug-in section 311 is inserted into the slot 131, the stoppers 314 gradually approach the end surfaces 1321 of the stop wall 132 as the plug-in section 311 is inserted deeper. When the stoppers 314 contact the end surfaces 1321, the plug-in section 311 is securely connected. Furthermore, the stoppers 314 housed in the receiving spaces 136 improve the compactness of the plug-in structure and enhance the stability of the connection between the plug-in section 311 and the slot 131.

[0093] like Figure 8 and Figure 9 As shown, one of the inner surface of the slot 131 and the outer surface of the plug portion 311 is provided with a second protrusion 137, and the second protrusion 137 is interference-fitted with the other. By providing the second protrusion 137, the firmness of the connection between the plug portion 311 and the mounting portion 13 can be improved.

[0094] 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 interference fit with the plug-in portion 311; in another embodiment, the outer surface of the plug-in portion 311 is provided with a second protrusion 137, and the second protrusion 137 is interference fit with the slot 131.

[0095] The present application does not particularly limit the shape of the second convex portion 137 . For example, the second convex portion 137 may be in the shape of an elongated strip or a hemispherical shape.

[0096] like Figure 1As shown, the receiving slot 3121 of the connector cover 31 has a second opening 3122 that opens parallel to the arrangement of the two mounting portions 13. The external connector can be inserted into the cover body 312 through the second opening 3122. In other words, the direction of insertion between the external connector and the connector cover 31 is parallel to the arrangement of the two mounting portions 13. This ensures that the stability of the connection between the connector cover 31 and the two mounting portions 13 is not affected when the external connector is inserted or removed.

[0097] like Figure 3 、 Figure 10 and Figure 11 As shown, the second shell 11 has a slot 114, and the first annular side wall 122, which is located at one end 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 side wall 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 side wall 122 can be improved, thereby preventing the shell wall near the notch 14 of the first annular side wall 122 from being concave inward and affecting the assembly of the connector assembly 30 and the housing 10.

[0098] like Figure 3 As shown, in one embodiment, a reinforcement portion 113 is provided inside the second shell 11 , and a clamping groove 114 is formed between the reinforcement portion 113 and the inner wall surface of the second annular side wall 112 of the second shell 11 .

[0099] Of course, in other embodiments, the second annular side wall 112 is thicker, and the latching groove 114 may also be formed in the second annular side wall 112 of the second shell 11 .

[0100] In summary, the relay of the embodiment of the present application has at least the following advantages and beneficial effects:

[0101] In the relay of the embodiment of the present application, after the relay body 20 is installed in the housing 10, it will squeeze the shell wall of the housing 10 and cause the housing 10 to expand outward to form an external support force, which in turn causes the two mounting portions 13 on both sides of the notch 14 to be subjected to the external support force and have a tendency 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. It can be seen that under the action of the external support force, the connector cover 31 can firmly clamp the two mounting portions 13, and the stability of the connection between the connector cover 31 and the housing 10 is significantly improved, avoiding the electrical connection between the conductive member 32 and the relay body 20 being affected by the shaking of the connector cover 31 relative to the housing 10. In addition, because the connector cover 31 and the two mounting portions 13 adopt a split connection method, the connector assembly 30 can be installed on the housing 10 at different angles, thereby adapting to external connectors in different installation environments and improving the versatility of the relay.

[0102] Furthermore, the second shell 11 is interference fit with the first protrusion 123 of the first shell 12, so that the second shell 11 plays the role of tightening the first annular side wall 122, reducing the magnitude of the external support force, and thus preventing 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.

[0103] Furthermore, 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 .

[0104] Furthermore, by inserting the first annular side wall 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 side wall 122 can be improved, thereby preventing the shell wall near the notch 14 of the first annular side wall 122 from being recessed inward and affecting the assembly of the connector assembly 30 and the shell 10.
