Japanese Unexamined Patent Application Publication No. 2014-222612 - With the plug according to PTL 1, heat is generated when a fuse blows.

The first conductive pin (10A) and the second conductive pin (10B) have thickness directions parallel to the third direction. Each of the first temperature sensor element (40A) and the second temperature sensor element (40B) has a temperature sensing surface (44) which is flat. The temperature sensing surface (44) of the first temperature sensor element (40A) faces the first conductive pin (10A) in the third direction. The temperature sensing surface (44) of the second temperature sensor element (40B) faces the second conductive pin (10B) in the third direction.
- With the plug according to the fourth aspect, it is possible to increase the amount of heat conducted from the conductive pins (10A and 10B) to the temperature sensor elements (40A and 40B). This thus enables further accurate detection of heat generated by the first and second conductive pins (10A and 10B).
- A plug according to a fifth aspect of the present invention can be achieved by a combination with any one of the second to fourth aspects. According to the fifth aspect, the plug further includes a first wall (317A) and a second wall (317B) which are electrically insulating. The first wall (317A) is located between the first conductive pin (10A) and the first temperature sensor element (40A). The second wall (317B) is located between the second conductive pin (10B) and the second temperature sensor element (40B).
- With the plug according to the fifth aspect, the conductive pins (10A and 10B) and the temperature sensor elements (40A and 40B) can be electrically insulated with reliability. Moreover, since the walls (317A and 317B) facilitate heat conduction from the conductive pins (10A and 10B) to the temperature sensor elements (40A and 40B), the accuracy of detection of heat generated by the conductive pins (10A and 10B) increases.
- A plug according to a sixth aspect of the present invention can be achieved by a combination with any one of the second to fifth aspects. According to the sixth aspect, the plug further includes a plug body (30) which houses the fuse holder (50), the first temperature sensor element (40A), and the second temperature sensor element (40B). The plug body (30) has a first surface (311) and a second surface (331) in the first direction. The first conductive pin (10A) and the second conductive pin (10B) are attached to the plug body (30) such that a tip of the first conductive pin (10A) and a tip of the second conductive pin (10B) protrude from the first surface (311) of the plug body (30). The first temperature sensor element (40A) and the second temperature sensor element (40B) are located closer to the first surface (311) than to the second surface (331).
- With the plug according to the sixth aspect, the temperature sensor elements (40A and 40B) can be located further closer to the tips of the conductive pins (10A and 10B). In general, heat generation by the conductive pins (10A and 10B) occurs at the tip side. Thus, the accuracy of detection of heat generated by the conductive pins (10A and 10B) increases.
- A plug according to a seventh aspect of the present invention can be achieved by a combination with any one of the second to sixth aspects. According to the seventh aspect, the fuse holder (50) includes: a first terminal (51) which holds a first end (71) of the fuse (70); and a second terminal (52) which holds a second end (72) of the fuse (70). The first terminal (51) is spaced apart from the first conductive pin (10A) in the third direction. The second terminal (52) is spaced apart from the second conductive pin (10B) in the third direction.
- The plug according to the seventh aspect enables accurate detection of heat generated by the first and second conductive pins (10A and 10B). Moreover, the plug according to the seventh aspect reduces the possibility of causing confusion of heat generated by the fuse (70) with heat generated by the first and second conductive pins (10A and 10B).
- A plug according to an eighth aspect of the present invention can be achieved by a combination with the seventh aspect. According to the eighth aspect, the specific conductive pin (10) is the first conductive pin (10A). The first terminal (51) is electrically connected to the first conductive pin (10A). The second terminal (52) has a portion (522) for electrically connecting to a line corresponding to the first conductive pin (10A).
- The plug according to the eighth aspect enables overcurrent protection with a simple structure.
- Although the present invention has been described and illustrated in detail, it is clearly understood that the same is by way of example only and is not to be taken by way of limitation, the scope of the present invention being limited only by the terms of the appended claims.
