no. 1 approach

[0081] like figure 1 and if figure 2 As shown, an electromagnetic relay 1 which is an example of the electronic device of the first embodiment includes an insulating case 10 having a connection end surface connected to a substrate or the like (that is, a fixed contact terminal 20 ) and a fixed contact side terminal 20 The substantially rectangular base 11 of the bottom surface) 15, the direction that covers this base 11 intersecting with the connection end surface 15 (that is, figure 1 and figure 2 The hollow box-shaped casing 12 on one end opening surface (ie, the upper surface) 14 on the upper and lower directions), the fixed contact side terminal 20 is fixed on the base 11, and has a substantially rectangular plate shape.

[0082] A substantially rectangular plate-shaped movable contact-side terminal 30 is fixed to the base 11 so as to be elastically deformable. In addition, the electromagnet part 40 and the movable part 50 connected to the movable contact side termina...

no. 2 approach

[0123] like Image 6 and Figure 7 As shown, the electromagnetic relay 1 according to the second embodiment of the present invention is different from the first embodiment in that the fixed contact side terminal 20 and the movable contact side terminal 30 are respectively provided with a sealing material arrangement part 70 (in the Image 6 and Figure 7 Only the sealing material arrangement part 70 of the fixed contact side terminal 20 is shown in , and the sealing material restricting part composed of the concave part 114 and the second part 116 is not provided on the base 11 .

[0124] In addition, in 2nd Embodiment, the same code|symbol is attached|subjected to the same part as 1st Embodiment, and description is abbreviate|omitted, and the point which differs from 1st Embodiment is demonstrated below.

[0125] The sealing structure of the electromagnetic relay 1 according to the second embodiment is realized by the fixed contact side terminal 20 , the movable contact sid...

no. 3 approach

[0146] like Figure 8 As shown, the difference between the electromagnetic relay 1 of the third embodiment of the present invention and the first embodiment is that the base 11 is equipped with an arrangement area forming part (that is, a sealing material restricting part) composed of a concave part 114 and a second part 116. part) 2, and the fixed contact side terminal 20 and the movable contact side terminal 30 respectively include the sealing material arrangement part 70 of the second embodiment.

[0147] In addition, in 3rd Embodiment, the same code|symbol is attached|subjected to the same part as 1st Embodiment and 2nd Embodiment, and description is abbreviate|omitted, and the point which differs from 1st Embodiment and 2nd Embodiment is demonstrated below.

[0148] The sealing structure of the electromagnetic relay 1 of the third embodiment is realized by the fixed contact side terminal 20 and the movable contact side terminal 30 of the second embodiment and the base 11 ...

Abstract

The invention provides a sealing structure of an electronic device. The electronic device (1) comprises: a casing (10), which uses a sealing material (60) to seal a base (11) and a casing (12), and is provided with a base ( 11) and the closed space (13) surrounded by the shell (12); at least one terminal (20), which has a main body (21) and a foot (22), wherein the base (11) has: a terminal groove (112 ), which accommodates the main body (21); the through hole (113), which accommodates the foot (22); the configuration area forming portion (2, 114, 116), which is connected to the main body (21), the foot (22), The terminal groove (112) and the through hole (113) are formed together from the outside of the housing (10) through the through hole (113) and the leg portion (22) and between the terminal groove (112) and the main body portion (21) An arrangement area of ​​the sealing material (60) extending toward the closed space (13).

Description

technical field [0001] The present invention relates to a sealing structure of an electronic device, an electronic device having the sealing structure, and a method of manufacturing the electronic device. Background technique [0002] Patent Document 1 discloses an electromagnetic relay including a case composed of a plate-shaped base, a box-shaped case covering one surface of the base in the thickness direction, and terminals fixed to the base. This electromagnetic relay has a sealing structure in which a junction between the base and the housing is sealed with a sealing material, and the airtightness inside the case is ensured by the sealing structure. [0003] Patent Document 1: (Japanese) Unexamined Patent Application Publication No. 2012-043642 [0004] In the above electromagnetic relay, the terminal is composed of a main body extending in the thickness direction of the base and fixed to the base, and a leg extending from the main body through the base in the thicknes...
