Abstract: A cutting tool according to this invention includes a cutting edge configured to cut a workpiece; a rake surface configured to come in contact with a chip, which appears when the workpiece is cut by the cutting edge; and a relieved surface configured to come in contact with a to-be-cut surface of the workpiece. A plurality of first grooves are formed on a cutting edge side of the rake surface. The plurality of first grooves includes a plurality of aligned grooves arranged adjacent to each other, and a connection groove connecting at least two of the plurality of aligned grooves to each other.

Abstract: The laser welding device includes a laser transmission window and a gas injection nozzle. The gas injection nozzle includes an optical path hole and an injection unit that injects an inert gas for shielding metal vapor into the optical path hole toward an irradiation direction side and an optical axis side of a laser beam.

Abstract: A housing holds a contact. A shield member is held in the housing and blocks electromagnetic waves. The shield member has a tubular shape, and the contact is arranged therein. The housing has an outer housing portion that is arranged outside of the shield member, and an inner housing portion that is arranged inside the shield member. The housing also has a joining portion that integrally joins the outer housing portion and the inner housing portion in an end portion on one side in a direction that is parallel to the direction of mating with the partner connector.

Abstract: A socket contact of small-size is provided for which detachment at solder from the print substrate is difficult. In the contact 1, a face in the thickness direction 120 of a front end portion of a pair of elastic arms 12a and 12b faces toward the insertion opening 21. When a blade contact 3 is inserted into an insertion opening 21, it is possible to open front end portions of a pair of elastic arms 12a and 12b in opposing directions. The configuration is such that, by providing first to third press fit fragments 111, 112, and 113 on a base unit 11, the same is securely held to the housing 2, so that only compressive stress acts on the pair of lead portions 11c and 11d, and can be made difficult to detach at solder from the print substrate 1p.

Abstract: A horizontal electric connector includes an insulating housing, a first electric contact, with a contacting part that is press-fitted into the housing from the rear and contacts a counterpart conductive part, and a leg that extends from the contacting part, comes out of the housing at the rear and descends, and a second electric contact, with a contacting part that is press-fitted into the housing from the rear at a position lower than the first electric contact and contacts a counterpart conductive part, and a leg that extends from the contacting part, comes out of the housing at the rear and extends forward along the bottom of the housing. A leg supporting part is provided on the bottom of the housing, into which the leg of the second electric contact is press-fitted from the rear, to prevent deformation of the leg.

Abstract: A high-voltage connector constructed as a base connector has an insulated housing (2) and two pin contacts (3, 4) held in two compartments (8, 9) separated by a partition (7) that is formed as an integral portion of the housing. Each pin contact consists of a connecting pin and a lead continuing from it, the connecting pins protruding in parallel towards the front opening of the housing (2), and each lead having a lower end to be soldered to a printed circuit board. The compartments (8, 9) are arranged in parallel and up and down on the circuit board. The leads of the pin contacts (23, 27) respectively extend down along the side walls (14, 15) of the housing, and the leads' lower ends (24, 28) are offset fore and aft relative to the housing.

Abstract: A structure such that a socket connector manufactured less expensively can engage with a base connector more reliably, adapted to employment in high-voltage connectors of a reduced height. The socket connector (1) has a socket housing (2) in which socket contacts (12) secured on wire ends (11) are placed side by side. The base connector (21) is of a shape to be surface-mounted on a printed circuit board (20). The socket housing (2) has a pair of lock arms (6) extending forwards from a rear end of and along lateral sides (4) of the socket housing. The socket housing further has tie pieces (5) capable of elastic deformation and formed integral with the lateral sides so as to support and operatively connect the lock arms (6) to the socket housing. The lock arms (6) have fore ends formed integral with hooks (7) projecting inwards and towards each other, and the lock arms (6) further have push lugs (8) extending backwards from their rear ends so as to be located in rear of the tie pieces (5).
