Abstract: A connector is selectably mateable with a first mating connector and a second mating connector. The first mating connector has a first interface and two lock portions. The second mating connector has a second interface. The connector comprises a shell. The shell has a standard portion, a modified portion and two coupling portions. The standard portion corresponds to both the first interface and the second interface. The modified portion and the coupling portions correspond not to the first interface but to the second interface. The modified portion is apart from the standard portion in an up-down direction. The coupling portion couples the standard portion and the modified portion. The shell is formed with two lock holes. The lock hole extends from the standard portion to the coupling portion. The lock holes receive the lock portions when the connector is mated with the first mating connector.

Abstract: A method of estimating a life of a gear pump includes detecting the number of rotations of a gear and a discharge amount of rubber being extruded from the gear pump; calculating, based on the number of rotations and the discharge amount of the rubber which are detected, a discharge efficiency ? (=T1/T) that is a ratio of a measured value T1 of a discharge amount of the rubber that is extruded from the gear pump per one rotation of the gear to a theoretical value T; and estimating the life of the gear pump based on the calculated discharge efficiency ?.

Abstract: A housing includes a plurality of contacts has a flat plate-shaped fitting portion projecting from a body portion to fit to a mating connector. The fitting portion has first and second main surfaces that are opposite each other and a pair of side surfaces connecting between those main surfaces. The contacts each have a contact portion disposed on the first main surface. The fitting portion is provided with a metal cover portion. The metal cover portion extends along a periphery of the fitting portion to cover the second main surface and the pair of side surfaces.

Abstract: A vehicle wheel 1 having a plurality of subsidiary air chambers 3, which is annularly incorporated on a rim outer peripheral surface 4, a cover member 13 having a lug part extended over the entire periphery and a stepped part extended over its periphery along the inside of the lug part 16, and a bottom plate member 14 being superimposed with each other through a seal member made of an elastic member and interposed therebetween in an airtight manner, and the cover member 13 and the rim outer peripheral surface 4 being joined to each other in a joint part 10, wherein the cover member 13 and the rim outer peripheral surface 4 are made into contact with each other so as to form a subsidiary air chamber 3 having air-tightness.

Abstract: A connector comprises contact pins, an insulator and a supplementary insulator. Each of the contact pins comprises a supported portion and a contact end. The insulator comprises accommodation portions which accommodate the respective contact pins. Each of the accommodation portions is provided with a supporting portion which includes a supporting surface and supports the supported portion of the corresponding contact pin. The supplementary insulator is fixedly held by the insulator. At least one part of the supported portion of the contact pin is placed between the supporting surface and the supplementary insulator in a Z-direction. Therefore, the supported portion always straightly extends in a Y-direction so that the contact end can be surely positioned at a predetermined position.

Abstract: In a connector member, each of contacts has a contact portion to be connected to a counterpart connector, a retention portion retained by an insulator, and a connecting portion to be connected with a cable. Each connecting portion is connected with the cable by soldering and projected from the insulator in an axial direction of the contact. Each connecting portion is formed obliquely in a contact pitch direction of the connector. A plug connector is provided with a shell on an upper surface of the connector member, and covered with a hood so as to expose a fitting portion.

Abstract: A connector including a first connector element and a second connector element that are coupled into a single unit, in which the first connector element has an engagement projection that projects interior of the first connector element and extends in the direction of the depth of the first connector element so that the front end of the engagement projection is spacedly apart from the front edge of the first connector element, and the second connector element is formed with an engagement slit that extends in the direction of depth of the second connector element and engages with the engagement projection of the first connector element.

Abstract: In a connector in which a conductive contacting portion (33) is supported by a spring portion (26) to be elastically movable in a first direction (28) and a second direction (29) perpendicular to the first direction, the contacting portion has a contact point (27) maintained in a specific condition such that the contact point is offset from a predetermined position in the second direction. The contact point is formed at its one end to be brought into contact with a mating object (17) in the first direction at the predetermined position. When the contacting portion is moved in a direction opposite to the first direction, the specific condition is released.
