[0005] Patent Document 1: Japanese Patent Application Publication No. 2016-201306 Summary of the invention

[0006] Problems to be solved by the invention

[0007] As a method of mounting an electromagnetic relay on a substrate, there is reflow soldering. In reflow soldering, solder is placed on the substrate in advance, and an electromagnetic relay is arranged thereon. Then, the electromagnetic relay is soldered to the substrate by heating the solder in a reflow furnace. By using such reflow soldering, the electromagnetic relay can be efficiently mounted on the substrate.

[0008] However, in the above-mentioned surface-mounted electromagnetic relay, depending on the configuration of the terminals, the balance in the state of being configured on the substrate is poor, and it is sometimes difficult to install on the substrate. For example, in the case where the terminals are asymmetrically configured on the bottom surface of the base, the electromagnetic relay is sometimes unable to maintain its posture and tilts when placed on the substrate. In this case, it is difficult to install by the above-mentioned reflow soldering. Alternatively, since the electromagnetic relay is configured unstably, the accuracy of installation on the substrate may be reduced. The object of the present invention is to provide an electromagnetic relay that can be stably mounted on a substrate even if the configuration of the terminals of the electromagnetic relay on the substrate is unstable.

[0009] Solutions to Solve Problems

[0010] An electromagnetic relay of one embodiment of the present invention comprises a base, a first contact terminal, a second contact terminal and a housing. The first contact terminal protrudes downward from the base. The first contact terminal includes a first bending portion. The first bending portion is arranged on a first side of the center line of the bottom surface of the base when viewed from above. The first bending portion is bent along the bottom surface of the base. The second contact terminal protrudes downward from the base. The second contact terminal includes a second bending portion. The second bending portion is arranged on a first side of the center line when viewed from above. The second bending portion is bent along the bottom surface of the base. The housing is mounted on the base and covers the base. The housing or the base includes a bracket portion. The bracket portion protrudes downward from the housing or the base. The bracket portion is arranged on a second side opposite to the first side relative to the center line of the base.

[0011] In the electromagnetic relay of this embodiment, the bracket portion suppresses the inclination of the electromagnetic relay when it is arranged on the substrate. Therefore, the posture of the electromagnetic relay before soldering can be stably maintained on the substrate. Thus, the electromagnetic relay can be stably mounted on the substrate.

[0012] The lower end of the bracket portion may be arranged on the same plane as the first bent portion and the second bent portion. In this case, the bracket portion can more stably maintain the posture of the electromagnetic relay before soldering on the substrate.

[0013] The electromagnetic relay may also include a first coil terminal and a second coil terminal. The first coil terminal may also protrude downward from the base. The first coil terminal may also include a third bent portion bent along the bottom surface of the base. The second coil terminal may also protrude downward from the base. The second coil terminal may also include a fourth bent portion bent along the bottom surface of the base. The third bent portion may also be arranged on the bottom surface of the base on the first side of the center line. The fourth bent portion may also be arranged on the bottom surface of the base on the second side of the center line. Alternatively, the third bent portion and the fourth bent portion may also be arranged on the bottom surface of the base on the first side of the center line. In this way, even if the configuration of the terminals of the electromagnetic relay is unstable, the posture of the electromagnetic relay can be stably maintained on the substrate by the bracket portion.

[0014] The lower end of the bracket portion may also be arranged on the same plane as the third bending portion and the fourth bending portion. In this case, the bracket portion can more stably maintain the posture of the electromagnetic relay before soldering on the substrate. The bracket portion may also be arranged on the housing. The bracket portion may also be arranged on the base.

[0015] The electromagnetic relay of another embodiment of the present invention comprises a base, a first contact terminal, a second contact terminal, a first coil terminal, a second coil terminal and a housing. The first contact terminal protrudes downward from the base. The first contact terminal includes a first bending portion. The first bending portion is bent along the bottom surface of the base. The second contact terminal protrudes downward from the base. The second contact terminal includes a second bending portion. The second bending portion is bent along the bottom surface of the base. The first coil terminal protrudes downward from the base. The first coil terminal includes a third bending portion. The third bending portion is bent along the bottom surface of the base. The second coil terminal protrudes downward from the base. The second coil terminal includes a fourth bending portion. The fourth bending portion is bent along the bottom surface of the base. The housing is mounted on the base and covers the base.

[0016] When viewed from above, the base and the shell include a first area, a second area, a third area, and a fourth area. The second area is symmetrically arranged with respect to the first center line with respect to the first area. The third area is symmetrically arranged with respect to the first area with respect to the second center line orthogonal to the first center line. The fourth area is symmetrically arranged with respect to the second area with respect to the second center line. The first bending portion, the second bending portion, the third bending portion, and the fourth bending portion are respectively arranged in any area other than at least one area of ​​the first area, the second area, the third area, and the fourth area. The shell or the base includes a bracket portion protruding downward from the shell or the base. The bracket portion is arranged in an area of ​​the first area, the second area, the third area, and the fourth area where the first bending portion, the second bending portion, the third bending portion, and the fourth bending portion are not arranged.

[0017] In the electromagnetic relay of this embodiment, the bracket portion suppresses the inclination of the electromagnetic relay when it is arranged on the substrate. Therefore, the posture of the electromagnetic relay before soldering can be stably maintained on the substrate. Thus, the electromagnetic relay can be stably mounted on the substrate.

[0018] The lower end of the bracket portion may be arranged on the same plane as the first bent portion, the second bent portion, the third bent portion, and the fourth bent portion. In this case, the bracket portion can more stably maintain the posture of the electromagnetic relay before soldering on the substrate.

[0019] The first bending portion and the second bending portion may also be arranged in the first area. The third bending portion may also be arranged in the third area. The fourth bending portion may also be arranged in the fourth area. The bracket portion may also be arranged in the second area. In this way, even if the arrangement of the terminals of the electromagnetic relay is unstable, the posture of the electromagnetic relay can be stably maintained on the substrate by the bracket portion. The bracket portion may also be arranged on the housing. The bracket portion may also be arranged on the base.

[0042] like Figure 6 As shown in FIG. 1 , the electromagnetic relay 1 includes a coil assembly 20, a clip 21, an armature 22, and a return spring 23. The coil assembly 20 generates an electromagnetic force that moves the movable contact 7 between an open position and a closed position. Figure 6 As shown in FIG. 1 , when the movable contact 7 is in the disconnected position, the movable contact 7 is away from the fixed contact 6.

The coil assembly 20 includes a coil 24, a bobbin 25, an iron core 26, a yoke 27, a first coil terminal 28 and a second coil terminal 29.

[0043] The coil 24 is wound on the winding drum 25. Although not shown in the figure, the ends of the coil 24 are connected to the first coil terminal 28 and the second coil terminal 29, respectively. The winding drum 25 is supported by the base 5.

The first yoke portion 34 is connected to the iron core 26. The second yoke portion 35 extends upward from the first yoke portion 34.

[0045] The first coil terminal 28 and the second coil terminal 29 are supported by the reel 25 and the base 5. The first coil terminal 28 and the second coil terminal 29 extend upward from the reel 25. The first coil terminal 28 and the second coil terminal 29 protrude downward from the base 5 to the outside of the electromagnetic relay 1.

[0046] The winding drum 25 includes a first winding drum hole 36. The first winding drum hole 36 is provided in the lower flange 33. The base 5 includes a third base hole 13. The first coil terminal 28 is pressed into the first winding drum hole 36. Alternatively, the first coil terminal 28 may be pressed into the third base hole 13.

Although not shown in the figure, the winding drum 25 includes a second winding drum hole identical to the first winding drum hole. The base 5 includes a fourth base hole identical to the third base hole 13. The second coil terminal 29 protrudes downward from the base 5 through the second winding drum hole and the fourth base hole.

[0047] The first coil terminal 28 includes a third straight portion 41 and a third bent portion 42. The third straight portion 41 extends downward from the base 5.

[0048] like Figure 6 As shown, the card 21 includes a rotating shaft 51, a pressing portion 52, and a receiving portion 53. The rotating shaft 51 is rotatably supported by the base 5. The pressing portion 52 is disposed opposite to the second contact terminal 9. The receiving portion 53 is disposed opposite to the armature 22.

[0049] The armature 22 includes a first armature portion 54 and a second armature portion 55. The armature 22 has a shape bent between the first armature portion 54 and the second armature portion 55. The first armature portion 54 is arranged above the iron core 26. The first armature portion 54 is arranged opposite to the iron core 26. The second armature portion 55 extends downward from the first armature portion 54. The second armature portion 55 is arranged opposite to the receiving portion 53 of the clamping member 21.

[0050] The armature 22 is supported by the second yoke portion 35. The armature 22 is supported to be rotatable around the upper end of the second yoke portion 35. The return spring 23 is connected to the armature 22. The return spring 23 is a hinge spring. The return spring 23 applies force to the armature 22 in the direction in which the second armature portion 55 is away from the receiving portion 53 of the clip 21.

[0051] Figure 8 4 is a three-dimensional diagram of the housing 4. Figure 8As shown, the housing 4 has a box-like shape, and the box-like shape includes an opening 60 opened downward. The housing 4 is separate from the base 5. The base 5 is arranged in the opening 60. The housing 4 covers the base 5 from above. The housing 4 is mounted on the base 5, covering the fixed contact 6, the movable contact 7, the coil assembly 20, the card-shaped member 21, the armature 22 and the return spring 23. The housing 4 includes a top surface 61, a first side surface 62, a second side surface 63, a third side surface 64 and a fourth side surface 65.

[0052] The top surface 61 is arranged above the base 5. The first side surface 62, the second side surface 63, the third side surface 64, and the fourth side surface 65 extend downward from the top surface 61. The first side surface 62 is arranged on the left side of the base 5. The second side surface 63 is arranged on the right side of the base 5. The third side surface 64 is arranged in front of the base 5. The fourth side surface 65 is arranged at the rear of the base 5. The lower ends of the first side surface 62, the second side surface 63, the third side surface 64, and the fourth side surface 65 are arranged in the same plane as the bottom surface 59 of the base 5. In addition, the lower ends of the first side surface 62, the second side surface 63, the third side surface 64, and the fourth side surface 65 may be arranged at different heights from the bottom surface 59 of the base 5.

[0053] Next, the operation of the electromagnetic relay 1 will be described. In the following description, the direction in which the movable contact 7 approaches the fixed contact 6 is defined as the closing direction, and the direction in which the movable contact 7 moves away from the fixed contact 6 is defined as the opening direction. Figure 6 As shown, the movable contact 7 is away from the fixed contact 6 .

[0054] When current flows through the coil 24, the first armature portion 54 is attracted to the iron core 26 by the electromagnetic force generated by the coil 24. As a result, the armature 22 overcomes the force of the return spring 23 and rotates. When the armature 22 rotates, the second armature portion 55 presses the receiving portion 53 of the clip 21 in the closing direction. As a result, the clip 21 rotates in the closing direction, and the pressing portion 52 of the clip 21 presses the second contact terminal 9 in the closing direction. The second contact terminal 9 is elastically deformed by being pressed by the pressing portion 52, and as a result, Figure 7 As shown, the movable contact 7 moves in the closing direction and contacts the fixed contact 6.

[0055] If the current flowing to the coil 24 is cut off, the electromagnetic force of the iron core 26 attracting the first armature part 54 disappears. Therefore, the armature 22 rotates in the opposite direction to the above by the force of the return spring 23. As a result, the clamp 21 rotates in the disconnection direction, and the second contact terminal 9 moves in the disconnection direction by the elastic force of the second contact terminal 9. As a result, the movable contact 7 moves in the disconnection direction and moves away from the fixed contact 6.

[0056] Next, the configuration of the first contact terminal 8, the second contact terminal 9, the first coil terminal 28, and the second coil terminal 29 will be described. Figure 4 and Figure 5 As shown, the first straight portion 15 of the second contact terminal 9 extends downward from the base 5. The first bent portion 16 of the first contact terminal 8 is bent along the bottom surface 59 of the base 5. The second straight portion 17 of the second contact terminal 9 extends downward from the base 5. The second bent portion 18 of the second contact terminal 9 is bent along the bottom surface 59 of the base 5.

[0057] The third straight portion 41 of the first coil terminal 28 extends downward from the base 5. The third bent portion 42 of the first coil terminal 28 is bent along the bottom surface 59 of the base 5. The fourth straight portion 43 of the second coil terminal 29 extends downward from the base 5. The fourth bent portion 44 of the second coil terminal 29 is bent along the bottom surface 59 of the base 5. The first bent portion 16, the second bent portion 18, the third bent portion 42, and the fourth bent portion 44 are arranged on the same plane.

[0058] like Figure 3 As shown, the first bent portion 16 of the first contact terminal 8 and the second bent portion 18 of the second contact terminal 9 are asymmetrically arranged on the bottom surface 59 of the base 5. In detail, the first bent portion 16 and the second bent portion 18 are asymmetrically arranged relative to the center line of the bottom surface 59 of the base 5 when viewed from above. The center line of the bottom surface 59 of the base 5 includes a first center line C1 and a second center line C2. The first center line C1 extends along the length direction of the bottom surface 59 of the base 5. In this embodiment, the length direction of the bottom surface 59 of the base 5 is the front-to-back direction. The second center line C2 is orthogonal to the first center line C1. That is, the second center line C2 extends in the left-right direction.

[0059] The first bending portion 16 and the second bending portion 18 are arranged on the left side of the first center line C1 on the bottom surface 59 of the base 5 when viewed from above. The first bending portion 16 and the second bending portion 18 are arranged on the bottom surface 59 of the base 5 behind the second center line C2 when viewed from above. The third bending portion 42 is arranged on the left side of the first center line C1 on the bottom surface 59 of the base 5 when viewed from above. The fourth bending portion 44 is arranged on the right side of the first center line C1 on the bottom surface 59 of the base 5 when viewed from above. The third bending portion 42 and the fourth bending portion 44 are arranged on the bottom surface 59 of the base 5 in front of the second center line C2 when viewed from above.

[0060] The bottom surface 59 of the housing 4 and the base 5 includes a first area A1, a second area A2, a third area A3, and a fourth area A4. The second area A2 is symmetrically arranged with respect to the first center line C1 with respect to the first area A1. The third area A3 is symmetrically arranged with respect to the first area A1 with respect to the second center line C2. The fourth area A4 is symmetrically arranged with respect to the second area A2 with respect to the second center line C2. The fourth area A4 is symmetrically arranged with respect to the first center line C1 with respect to the third area A3.

[0061] The first bend portion 16 of the first contact terminal 8 and the second bend portion 18 of the second contact terminal 9 are arranged in the first area A1. The third bend portion 42 of the first coil terminal 28 is arranged in the third area A3. The fourth bend portion 44 of the second coil terminal 29 is arranged in the fourth area A4.

[0062] In the asymmetric arrangement of the first contact terminal 8, the second contact terminal 9, the first coil terminal 28, and the second coil terminal 29, the electromagnetic relay 1 is easily unstable when placed on the substrate. Therefore, in the electromagnetic relay 1 of the present embodiment, the housing 4 includes a bracket portion 66 in order to stabilize the electromagnetic relay 1 when placed on the substrate.

[0063] The bracket portion 66 protrudes downward from the lower end of the housing 4. The bracket portion 66 protrudes downward from the lower end of the second side surface 63. The lower end of the bracket portion 66 has a flat shape. The lower end of the bracket portion 66 is arranged on the same plane as the first bent portion 16, the second bent portion 18, the third bent portion 42, and the fourth bent portion 44.

[0064] The bracket portion 66 is arranged on the opposite side of the first bending portion 16 and the second bending portion 18 relative to the first center line C1 when viewed from above. That is, the bracket portion 66 is arranged on the right side of the first center line C1 when viewed from above. The bracket portion 66 is arranged in the area of ​​the first area A1 to the fourth area A4 where the first to fourth bending portions 16, 18, 42, 44 are not arranged. That is, the bracket portion 66 is arranged in the second area A2.

[0065] In the electromagnetic relay 1 of the present embodiment described above, the bracket portion 66 suppresses the tilt of the electromagnetic relay 1 when arranged on the substrate. Therefore, the posture of the electromagnetic relay 1 before soldering can be stably maintained on the substrate. Thus, the electromagnetic relay 1 can be stably mounted on the substrate.
