摘要:
The present invention prevents two connector housings of a connector from being in a half-fitted condition by increasing restoring force which separates the two housing. A connector includes: a first connector housing including a lock projection; a second connector housing to be fitted to the first connector housing and integrally including a lock arm which is elastically deformed by the lock projection and is engaged with the lock projection; a lock ensuring member including a body which is attached to the second connector housing and movable between an allowing position and a preventing position, and an interference arm which is integrally provided on the body and includes a pressing projection. The pressing projection presses the lock arm while the lock projection deforms the lock arm at the allowing position, and the interference arm abuts the lock arm so as to prohibit the lock arm from deforming in the preventing position.

Disclosed is a soap making split mold composed of a set of splits 1A and 1B adapted to be assembled together to form a molding cavity 1C. The split 1A has a larger surface area in its recess 11A defining part of the cavity 1C than the other split 1B does in its recess 11B defining the other part of the cavity 1C. The ratio of the surface area of the recess 11A of the split 1A to that of the recess 11B of the split 1B ranges from 52:48 to 66:34. Otherwise, the split 1A has a larger surface roughness Ra in its recess 11A defining part of the cavity than the other split 1B does in its recess 11B defining the other part of the cavity. The difference of the surface roughness Ra between the recess 11A and that of the recess 11B is 0.1 to 30 μm.

Disclosed are a weld joint and a stainless steel-based weld metal composition for the weld joint. The composition and weld joint made therefrom are suitable for welding a zinc-based alloy coated steel sheet. The weld is excellent in corrosion resistance and liquid-metal embrittlement crack resistance. This is accomplished by inhibiting liquid-metal embrittlement cracks of the stainless-steel-based weld metal when the zinc-based alloy coating steel sheet is welded using the stainless-steel-based weld metal. The weld joint comprises a welded portion of weld metal made of stainless-steel-based components, the weld metal containing in mass percent (%): C: 0.01-0.1; Si: 0.1-1; Mn: 0.5-2.5; Ni: 5-11; and Cr: 17-25, and the balance being iron and residual impurities, wherein the following expression are met: −0.81×Cr equivalent+23.2≦Ni equivalent≦0.95×Cr equivalent−8.1 . . . (1); Ni equivalent=Ni+30×C+0.5×Mn+30×N . . . (2); Cr equivalent=Cr+Mo+1.5×Si . . . (3).
摘要:
A method of producing a lipped molded article comprising the steps of forming a molded article having an opening portion by papermaking and outwardly curling the peripheral wall portion which constitutes the opening portion to make a lip. The method is characterized in that the inner surface of the molded article is coated with a resin layer to make a multilayer molded article, the part to be curled of the peripheral wall portion of the molded article is impregnated with a liquid, and the part to be curled is subjected to curling processing while or after being heated.

A heat-insulating container having a first fiber layer (111) with a prescribed density and a second fiber layer (112) which is formed inside the first fiber layer (111) and has a lower density than the first fiber layer (111). The first fiber layer (111) is 0.2 to 1 mm thick, and the second fiber layer (112) is 0.4 to 3 mm thick, with the total thickness of the first fiber layer (111) and the second fiber layer (112) being 0.6 to 4 mm.
摘要:
A guide rib is protrusively formed on a bottom face of a connector housing to position the connector housing to a printed circuit board by piercing the printed circuit board. A groove portion is hollowly formed around a base portion of the guide rib to disperse the screw tightening stress and prevent the guide rib from cracking as the connector is fixed to the printed circuit board. It disperses stress caused by tightening a screw for connecting the connector housing with the printed circuit board, and therefore prevents cracking on the base portion of the guide rib resulting from concentration of the stress. Since the groove portion is hollowed, the connector housing adheres securely to the printed circuit board, therefore resulting in a stable mounting.

A low insertion force connector with a downsized and simple structure and high reliability is provided, wherein coupled connectors are capable of sufficiently moving in the uncoupling direction. The low insertion force connector includes: a first connector having a first cam-projection, a frame with a cam-opening to slidably accommodate the first connector in the coupling direction, a second connector with a coupling portion and a cam-engaging slit to be couples with the first connector in the frame, and a slider attached to the second connector, provided with a second cam-projection which engages both of the cam-opening and the cam-engaging slit, and provided with a cam groove consisting of a connector coupling cam groove and a shift-allowing cam groove continuing to the connector coupling cam groove. Thus, a low insertion force connector with a downsized and simple structure and high reliability can be realized.

A connector coupling device comprises a first connector in which a slide plate having a cam groove is provided being capable of sliding so as to traverse the first connector, a second connector having a fitting projection which is engaged with the cam groove for coupling the second connector with the first connector when the slide plate is slid toward a first direction, and which is removed from the cam groove for removing the second connector from the first connector when the slide plate is slid toward a second direction opposed to the first direction, a coupling case having a first opening into which the first connector is inserted and a second opening into which the second connector is inserted and slidablly mounted therein, and a fitting support member urging one end portion of the slide plate toward the first direction while the first connector is pushed toward the second connector inside of the case in a third direction perpendicular to the first and second directions for coupling the first connector with the second connector.
摘要:
A board mounting-type connector in which an external force, applied to the connector, will not act directly on solder portions on the connector, and the efficiency of an assembling operation is high. A board mounting-type connector (6) is fixed to a board (10) supported within an equipment body (16), and projects outwardly from a connector opening (18) formed in an equipment cover (7) which cooperates with the equipment body to cover the board (10). Board terminals (8) are soldered at their one ends (8a) to the board (10), and other end portions (8b) of the board terminals are received in the connector. Connector-supporting projections (14) are formed on an outer peripheral surface of that portion of the connector projecting outwardly from the connector opening (18), and the connector-supporting projections abut against a peripheral edge portion of the connector opening (18) so that an external force, applied to the connector in a direction toward the board (10), can be supported by the equipment cover (7).
