a reed switch

Abstract

The technical field of the reed switch of the present invention particularly relates to a reed switch, which includes a tube body and a first magnetically permeable metal conductor and a second magnetically permeable metal conductor arranged at one end of the tube body, the first magnetically permeable metal conductor includes a first lead The foot segment and the first elastic segment, the second magnetically permeable metal conductor includes the second pin segment and the second elastic segment, one end of the first pin segment and one end of the second pin segment are located inside the tube body, the first elastic The other end of the segment faces the direction where the other end of the tube body is located, the other end of the second elastic segment faces the direction where one end of the tube body is located, and the other end of the second elastic segment overlaps with the other end of the first elastic segment; When triggered, there is a gap between the other end of the second elastic segment and the other end of the first elastic segment, and the reed switch is not conductive; when triggered, under the action of the magnetic field, the other end of the second elastic segment is connected to the first elastic segment. The other ends of the segments touch each other, and the reed switch conducts. The pins are at the same end of the tube body, which can reduce the space occupied by the pins and reduce the size of the reed switch.

Description

technical field [0001] The invention relates to the technical field of reed switches, in particular to a reed switch with two pins at the same end. Background technique [0002] At present, the pins of the existing dry reed switches, no matter normally open or normally closed, or switching types, are located at both ends of the glass tube, which is no problem for most applications, but for some In occasions where the use space is limited, it is necessary to do some professional processing on the reed switch, which is very difficult and risky, such as bending or shortening the pins. Even so, it is more extreme for some space restrictions. occasions are still difficult to meet the requirements. The method of reducing the size of the reed switch is generally to use a shorter glass tube, but that will require a higher manufacturing process for the reed switch, resulting in a substantial increase in cost.

[0002] At present, the pins of the existing dry reed switch, no matter normally open or normally closed, or switching type, are located at both ends of the glass tube, which is no problem for most of the occasions, but for some In occasions where the use space is limited, it is necessary to do some professional processing on the reed switch, which is very difficult and risky, such as bending or shortening the pins. Even so, it is more extreme for some space restrictions. It is still difficult to meet the requirements

The method of reducing the size of the reed switch is generally to use a shorter glass tube, but that will require a higher manufacturing process for the reed switch, resulting in a substantial increase in cost

Because the pin must be connected with the external circuit, it must occupy a certain space, and the two pins are located at one end, so that each end needs to occupy a certain space, and the occupied space is relatively large, which is difficult to use in places where space is limited.
