更に離れ易さを助長している。Therefore, if the electrode is repeatedly attached to and detached from the electrode several times, the rubber and the spring are separated from each other, and the life of the connector is very short. The cause of the peeling is that the spring and the rubber are usually formed by an injection method, so that the adhesive strength between the rubber and the spring is almost zero. Further, when the connector is separated from the electrode, there is a tendency to pull the lead wire side of the rubber as it is, and when the connector is separated in this way, it just turns like a spring. For this reason,
Furthermore, it facilitates easy separation.
【０００４】本発明の目的は、心電測定器用コネクター
において、離れ難いばねを提供することである。An object of the present invention is to provide a spring which is hard to separate in a connector for electrocardiograph.

Reference numeral 1 denotes a spring body, and an electrode fitting concave portion 3 incorporating a wire spring 2 is formed on the spring body 1 side, and a peripheral edge thereof is raised. Reference numeral 4 denotes a washer in which the spring body 1 is caulked to the lower surface, and a ring-shaped rib 5 is formed around the washer 4. Although the rib 5 in the embodiment has a ring shape, a simple protrusion may be formed around the washer 4.
