Abstract: A connector includes a sphere serving as a contact portion and a support member rotatably and elastically supporting the sphere. The sphere and the support member form an electrical connection path. The connector may further include a housing fixed to the support member, wherein the housing has a through hole sized such that the sphere cannot pass therethrough, and the sphere protrudes through an opening of the through hole to outside of the housing.

Abstract: Provided is a spring connector capable of preventing deformation of a waterproof elastic member from being spread to a periphery. A spring connector includes a first pin having a contact part with an object, a spring for applying a contact force with the object to the first pin, an intermediate member held by the first pin so as to move together with the first pin by pressing-in or the like, and a waterproof elastic member which is interposed between the first pin and the intermediate member and watertightly seals a space between the first pin and the intermediate member.

Abstract: A spring connector includes a movable pin, a conductive tube accommodating a base portion of the movable pin, a spring provided in the conductive tube so as to urge the movable pin in a direction, in which the movable pin protrudes from the conductive tube, and a plate spring contact including a plurality of plate springs that electrically connect the movable pin and the conductive tube to each other. The plurality of plate springs are provided around an entire circumference of the movable pin and are in elastic contact with an inner circumferential surface of the conductive tube, respectively.

Abstract: A spring connector, includes: an electrically conductive metal tube, having a bottomed hole; a plunger, which is provided in the bottomed hole so as to freely move in an axial direction and so as not to slip out from the bottomed hole, and an tip end portion of which is protruded from the bottomed hole; and a spring coil, provided in the bottomed hole, and elastically urging the plunger in a protruding direction. The electrically conductive metal tube includes a small diameter tube part having a smaller outer diameter at a distal end side thereof from which the plunger protrudes, and a soldering part being larger than the small diameter tube part in width in a direction perpendicular to the axial direction, at a backward side of the small diameter tube part in the axial direction, and a face of a distal end side of the small diameter tube part is separated from the soldering part in the direction perpendicular to the axial direction.

Abstract: A spring connector includes: an electrically-conductive pin; an electrically-conductive tube, having the pin slidably received therein, the tube holding the pin in such a condition that at least part of the pin projects from one end of the tube in a first direction, and the other end of the tube being open; and a housing, including a hole portion which can receive the tube, and a slit exposing at least part of an outer peripheral surface of the tube to an exterior, the housing having a first wall portion opposed to the other end of the tube and formed with a projecting portion projecting in the first direction and fitting to the other end of the tube. The at least part of the outer peripheral surface of the tube which is exposed from the slit is electrically connectable to a board.
