A terminal fitting (10) has a forwardly open tube (11) for receiving a male tab (T). An inner resilient contact piece (16; 22) has a base end (16A; 22A) unitary with a first wall of the tube (11) and an outer resilient contact piece (15; 21) has a base end (15A; 21A) unitary with a second wall of the tube (11). The respective base ends (15A, 21A; 16A, 22A) are in face-to-face contact, but a clearance (17; 23) is defined between the resilient contact pieces (16, 22; 15, 21) forward of the base en...

A female terminal fitting (10) is provided with a box-shaped main portion (11) into which a mating tab (61) is insertable, and a resilient touching piece (12) having a projection as a contact projection (32) that can contact the tab (61) is provided in the main portion (11). The tab is formed by folding the opposite widthwise sides of a metal plate in a thickness direction and causing the end edges of the folded parts to face each other. A flat surface (35) of the contact projection (32) comes i...

Disclosed herein is an improved tube fitting of the swage variety which employs a body part, at least one ferrule designed to slip around a tube, and a nut used to compress the ferrule against the tube and the body part and thereby form a leak-tight connection between the tube and the body part. The nut is divided into two parts which are movably interconnected by a radially flanged tubular portion of one of the nut parts. This flanged tubular portion engages the ferrule and prevents rotation of...

A tubing fitting for use in microsurgery including a female tubing fitting and a male tubing fitting. The female tubing fitting has an external surface with a pair of opposing projections disposed thereon and an internal bore. The male tubing fitting has a second internal bore and a collar at least partially surrounding the second internal bore. The collar has an internal surface with two pairs of opposing sloping ramps disposed thereon. The pairs of opposing sloping ramps are arranged so as to ...

A unitary tubular fitting body and cooperating mandrel for installation on a blind wall. The body includes an axially collapsible tube portion which during installation draws up the body into alignment with the wall. The body includes a frangible ring dimensioned to fail after adequate compression force is applied on the collapsing tube portion for full sealing engagement with the wall. Failure of the ring releases the mandrel and prevents overtightening of the fitting. BACKGROUND OF THE INVENTI...

Apparatus for connecting a flexible pipe made of material such as polybutylene to a rigid component of a piping system made of metal or rigid thermoplastic material such as chlorinated polyvinylchloride. The apparatus comprises a compression fitting to which the rigid material can be connected, such as by a threaded connection, solvent weld or the like, and to which the flexible pipe can be connected by a compression joint which will provide a tight seal without cutting, abrading or otherwise ca...

A connector for a fluid conduit is provided herein. The connector includes a conduit structure and an annular seal member. The conduit structure has a frustro-conical surface and a seal groove. The frustro-conical surface may be an external surface or an internal surface, depending upon the desired configuration of the connector. The seal groove is formed into the frustro-conical surface along an axis perpendicular to the frustro-conical surface. The seal groove is preferably defined by a consta...

A tube fitting capable of absorbing vibration and shock resulting from a high pressure fluid passing through the tube fitting while it is used includes a connection head, a connection nipple, and an intermediate connection member. The connection head and the connection nipple are provided with an annular collar projecting from an end surface of the connection head and the connection nipple. The connection head, the connection nipple and the intermediate connection member are joined by inserting ...

A terminal fitting (T) has a rectangular tube (10). A resilient locking piece (25) is accommodated in a rectangular tube portion (10) and a locking hole (19) in the tube (10) exposes the resilient locking piece (25). A side plate (13R) of the rectangular tube (10) is provided with an intrusion restricting portion (21) near the resilient contact piece (25) and in an opening area of the locking hole (19). Thus, the intrusion of an external matter through the locking hole (19) can be restricted by ...

A terminal fitting (A) has a receiving portion (17) with a contact surface (18) for contacting a male tab (T). The contact surface (18) is widest at the front end and substantially narrowed toward the back. A rate at which a contact area of the male tab (T) and the contact surface (18) increases in the insertion process of the male tab (T) is smaller as compared to a substantially rectangular contact surface having a constant width. The terminal fitting (A) provides good operation feeling upon m...
