A busbar is placed on an anvil, and a core wire of a cable is placed on the busbar. While the core wire is pressed onto the busbar using a horn chip, ultrasonic vibration is given to the core wire to join the core wire to the busbar. The horn chip has two flat portions and a recessed portion located between the flat portions. When the core wire is pressed onto the busbar using the horn chip, each of the flat portions and the busbar sandwich a part of the core wire therebetween while the recessed portion and the busbar put a remaining part of the core wire therebetween. Each of the sandwiched parts of the core wire does not reach an outer end of the corresponding flat portion to leave a space between the corresponding flat portion and the busbar.

A differential signal connector includes a plurality of pairs of signal contacts, a plurality of ground contacts, and an insulating housing holding the signal contacts and the ground contacts. On a first connection side for connection to a connection partner, the ground contacts are arranged on both sides of each pair of signal contacts so that a contact array of a fixed pitch is formed. On a second connection side for connection to a board, the ground contacts are arranged spaced apart from each other in a first row, while the pairs of signal contacts, which are adjacently arranged on both sides of the ground contact on the first connection side, are arranged so as to be allocated in a second row and a third row located on both sides of the first row so that the pairs of signal contacts are arranged zigzag on the second connection side.

Differential signal connector capable of reducing skew between a differential signal pair

One lane is formed by a combination of two signal pins S and adjacent one or two ground pins G of a connector that handles differential signals. When allocating differential signals to pins staggered in two rows, for pin allocation on the board soldering side, (SGS) is allocated to a left end of a first row to form a first lane and then (SGS) is allocated to odd-numbered lanes and (GSSG) to even-numbered lanes while (GSSG) is allocated to a left end of a second row to form a first lane and then (GSSG) is allocated to odd-numbered lanes and (SGS) to even-numbered lanes.

Connector

Preparation is made of first and second contact assemblies in each of which ends of a plurality of contacts are respectively coupled to a plurality of coupling portions of a carrier. The coupling portions of at least one of the first and second contact assemblies are bent so as to offset the contacts in a thickness direction of the carrier. Then, the first and second contact assemblies are combined together in a state where the carriers overlap each other and the contacts are aligned with and spaced apart from each other in the same plane. After integrating the contacts, the coupling portions are cut off. Then, the integrated contacts are collectively inserted into a shell.

Methods of manufacturing a connector component having a narrow-pitch connector group

A connector has a plurality of high-speed differential signal lanes each of which includes two first contacts for high-speed differential signal transmission and two ground contacts. A second contact which does not belong to the high-speed differential signal lanes is arranged between the high-speed differential signal lanes. On a first connection side for connection with a connecting object, contacting portions of the contacts are arranged in a single row at a distance from one another. On a second connection side for connection with a mounting object, terminal portions of the first contacts and terminal portions of the ground contacts are arranged in a first row at a distance wider than that between the contacting portions while a terminal portion of the second contact is arranged in a second row.

A receptacle of an electrical-optical hybrid connector including a plug having an insertion fitting part and the receptacle having a housing space that receives the insertion fitting part includes an optical connection part disposed in a space in communication with the housing space, and an electrical connection part disposed in front of the optical connection part, a shutter that is opened when the receptacle and the plug are connected to each other is provided in front of the optical connection part of the receptacle, and the optical connection part of the receptacle moves forward in association with the shutter when the shutter is opened, and moves rearward in association with the shutter when the shutter is closed.

Electrical-optical hybrid connector and receptacle thereof

A differential signal connector includes a plurality of pairs of signal contacts, a plurality of ground contacts, and an insulating housing holding the signal contacts and the ground contacts. On a first connection side for connection to a connection partner, the ground contacts are arranged on both sides of each pair of signal contacts so that a contact array of a fixed pitch is formed. On a second connection side for connection to board, the ground contacts are arranged spaced apart from each other in a first row, while the pairs of signal contacts, which are adjacently arranged on both sides of the ground contact on the first connection side, are arranged so as to be allocated in a second row and a third row located on both sides of the first row so that the pairs of signal contacts are arranged zigzag on the second connection side.

Electrical connector

In an optoelectrical connector that is composed of a plug including an insertion fitting part and a receptacle including a housing space into which the insertion fitting part of the plug is inserted, the plug is provided with an optical connection part on a front end of the insertion fitting part and an electric connection part more rearward than the optical connection part. The receptacle is provided with an optical connection part on the deep side of the housing space and an electric connection part more frontward than the optical connection part. A shutter is formed on the immediate front of the optical connection part of the receptacle and the shutter opens in the optical connection. Deterioration of optical coupling efficiency caused by attachment of metal abrasion powder, which is generated in a slide between the electrical connection parts in the electrical connection, to the optical connection parts, is prevented.

Optoelectrical connector

By using a lead frame as an intermediate member, a contact group of a connector is manufactured. The lead frame includes a plurality of first leads arranged on a plane and spaced from one another, a plurality of pairs of second leads, each pair being arranged on the plane between the first leads, and a connecting portion connecting the first and the second leads on one end side. The second leads have a pitch which is greater on the other end side than that on the one end side to make the second leads approach the first leads on the other end side, respectively. The lead frame further includes bridge portions connecting approached ones of the first and the second leads to each other at a portion where an interval between the first and the second leads is reduced.

An assembly comprises first connection units attached to a shelf and second connection units attached to cards, respectively. Each first connection unit holds at least one first optic fiber, while each second connection unit holds at least one second optic fiber. The first connection unit is connected to the second connection unit so that the first optic fiber is connected to the second optic fiber. Each first connection unit comprises a body and an optic connector. Each body is floatingly supported by the shelf. Each optic connector is floatingly supported by the corresponding body. The double floating-support structure allows 'blind mate' connections between the first and the second connection units.
