Abstract: Provided are a resin composition for 3D printer which is low in viscosity, is good in handleability by 3D printers and can give shaped products excellent in flexibility in a broad temperature range, and a method for producing the same, and a cured product of the resin composition. The resin composition for 3D printer of the present invention contains a first monomer, a second monomer, and a photopolymerization initiator, wherein the first monomer is a reaction product of a particular polyether polyol, a polyisocyanate and a particular compound having a (meth)acryloyl group; the total number of moles of the hydroxyl group of the polyether polyol and a group reactive with isocyanate group of the compound having a (meth)acryloyl group is equal to the number of moles of the isocyanate group of the polyisocyanate; and the second monomer is a (meth)acrylic compound.

Abstract: A terminal support has a first main body. Wall plates are arrayed on the first main body in a first direction so as to define a first space between each of adjacent ones of the wall plates. The first space is adapted to receive a terminal having a blade portion and a sheathed electric wire. The blade portion extends in the first direction, and no clearance is formed between both ends in the first direction of the terminal and the adjacent ones of the wall plates. Chamfered portions are formed on both sides in the first direction of a tip end of each of the wall plates. A punch has a second main body. Press members are arrayed on the second main body in the first direction so as to define a second space between each of adjacent one of the press members.

Abstract: An electrical connector has a terminal piece connected to an electrical cable, a connector housing receiving the terminal piece, and a terminal holder attached to the connector housing. The holder presses the terminal piece against a wall of the connector housing so that the terminal piece is sandwiched between the wall and the holder. The holder has a first boss projecting from a base plate of the holder toward the retainer wall such that the first boss can contact a main plate of the terminal piece to press the main plate against a retainer wall of the connector housing. The holder has a second boss projecting from the base plate toward the retainer wall such that the second boss can contact a cable connection end of the terminal piece to press the cable connection end against the retainer wall.

Abstract: A press-clamping portion 13 includes a pair of braid press-fastening portions 17 which extend in an upstanding manner respectively from opposite side edges of a terminal bottom plate portion 11, and can be press-connected to a braid 15 of a coaxial cable 3 by press-fastening, and a connecting piece portion 25 which can be inserted at its distal end portion between an inner insulating layer 23 of the coaxial cable 3 and the braid 15 from the end side of the coaxial cable 3 so that the braid 15 can be held between the connecting piece portion 25 and distal end portions of the braid press-fastening portions 17. Grooves 29 of a triangular cross-section are formed in an inner surface of the press-clamping portion 13, and extend in respective directions intersecting a direction of insertion of the coaxial cable 3.

Abstract: A connector 2 includes a connector housing 3, terminal metal fittings and a packing 1. The connector housing 3 which accommodates the terminal metal fittings is coupled with a complementary connector housing. The packing 1 keeps watertight the boundary between the connector housing 3 which is an article and supplementary connector housing 6 which is another article. The packing 1 includes a ring-shaped packing body 13, outer and inner protruding pieces 14 and 15; which protrude from the outer and inner edges of the packing body 13, respectively, holes 16 and securing pieces 17. The thickness of the packing body 13 is larger than the width thereof. Protruding pins 11 of the connector housing 3 are inserted in the holes 16, respectively. The securing pieces 17 are secured in receiving holes of the connector housing 3.
