An electrical cable connector comprises a plurality of female contacts,and a plurality of cables,. The female contacts,are aligned and retained in a row extending in a right and left direction in an insulative housing,, and one end of each cable is connected to a corresponding female contact in the insulative housing,. Each of the female contacts comprises a base portion,, which is fixed in the insulative housing,and to which the core wire of a corresponding cable,is connected, and a resilient arm portion,, which is continuous from the base portion,and extends along the base portion,with a predetermined distance therebetween. When this connector is engaged with a matable connector, each female contact receives and holds a corresponding male contact of the matable connector in a space between the base portion,and the resilient arm portion,, thus establishing the electrical connection of the female and male contacts.

The female contacts,are aligned and retained in a row extending in a right and left direction in an insulative housing,, and said shield cover,is mounted on the insulative housing,. A plurality of insertion openings,are provided at the front of the insulative housing,, and the male contacts of a matable connector being inserted through the insertion openings,into the shielded connector are engaged with the female contacts,. The shield cover,is formed of an electrically conductive plate and bent in a &ldquo;U&rdquo; figure, and it is provided with a plurality of through holes,. When the shield cover,is mounted on the insulative housing,, covering the upper and lower surfaces and the front surface thereof, the through holes,of the shield cover,meet the insertion opening,of the insulative housing

Shielded connector

A surface-contact connector comprises a plurality of terminals 50 and a housing 11. The terminals 50 are made of an electrically conductive, resilient material and are formed in an identical shape. These terminals 50 are retained in the housing 11 in a row. Each terminal 50 includes an anchoring portion 51, an resilient portion 54, and a contacting portion 55. The anchoring portion 51 is fixedly retained in the housing 11, and the resilient portion 54, which is capable of elastic deformation, extends from the anchoring portion 51. The contacting portion 55 is continuous from a front end of the resilient portion 54 to protrude in the direction of engagement with a part to be electrically connected to. The housing 11 is provided with protrusion-regulating portions 16 and 17 which meet with the resilient portions 54 or contacting portions 55 of the terminals to regulate the amounts of protrusion of the contacting portions 55 in the direction of the engagement.

Surface-contact connector

A right angled header connector assembly including a main housing having a circuit board connecting face from which respective circuit board connecting portions protrude horizontally rearward and forward therefrom for reflow soldering to the circuit board and a transverse mating face. A subhousing is releasably attachable to the main housing to extend forward at the mating face surrounding the mating portions of the contact elements and in adjacent covering relation to the forward protruding circuit board connecting portions subsequent to the reflow soldering step. Release of the subhousing from the mating face, enables access to the forward protruding circuit board connecting portions for the reflow soldering step, unimpeded by said subhousing.

Electrical connector assembly

An electrical connector of a right angle header type including a housing with a series of contact members having connecting portions and lead portions at mating and rear faces, respectively, the lead portions being bent through 90 degrees forming medial portions extending rearward from the rear face and board connecting portions extending downward so that free ends of the board connecting portions are insertable into respective connecting through-holes of a circuit board. A lead portion retaining member having lead portion locating groves on a lower face is releasably attached to the housing to extend over the medial portions to prevent upward movement thereof during insertion of the end portions into the respective connecting through-holes, thereby obviating risk of misjudgement that the connector is correctly installed on the circuit board. A lead locating and guiding member has a series of lead receiving apertures at positions corresponding to the connecting holes of the circuit board receiving respective connecting portions and is mounted on the housing for sliding movement from a first, lead locating position, receiving respective connecting portions at locations adjacent respective free ends thereof, to a second position, remote from the free ends, during movement of the board connecting portions progressively into respective connecting through-holes of the circuit board.

Circuit board connector

An insulation displacement connector for flat cable comprising an insulating housing and one piece terminals, each having a mating contact portion and a slotted plate wire connecting portion joined by a conducting lead portion. All the mating contact portions are mounted in a common plane at the mating face as a row extending transversely of a mating direction and the wire connecting portions are arranged as four rows extending transversely of the cable axis and at predetermined spacings apart in an axially rearward direction. Respective wire connecting portions of first and third rows being at predetermined transverse separations from respective adjacent wire connecting portions of the second and fourth rows, respectively, and conducting lead portions of the first and second rows are crooked upward and transversly of the axis so that respective wire connecting portions of the third and fourth rows are axially aligned behind them and at a lower level so that respective flat cable conductors can be terminated therein at the two levels without interfering with each other.

Insulation displacement connector

A surface mount electrical connector having lead portions of first and second series of terminals extending in alternating closely spaced parallel relation across a circuit board from a rear face of a connector housing. The lead portions have transverse soldering portions on respective free ends and the lead porions of the second series are longer than those of the first series and the lead portion of each series are of equal length so that the soldering portions of the first and second series are located in first and second rows with the first row being closer to the housing than the second row. The soldering potions of the first row have respective upstanding heater engaging portions so that the heater can be brought into engagement therewith without interfering with adjacent lead portions or with soldering portions of the other row.

Surface mount electrical devices

A surface mount connector comprises two assemblable housing parts for engagement with a circuit board and for mating with a complementary connector respectively. A series of contacts are anchored in the board engaging part and the other mating part is provided with contact locating surface portions which engage and press the contacts into a coplanar circuit board engaging position when the two housing parts are assembled together.

A multi-way, electro-optic connector comprises an optical fiber plug connector 1 and an electro-optic receptacle connector 100. Identical cover members 2 and 3, of the plug connector 1 define divergently curving optical fiber guiding channels 23 of at least a minimum curvature obviating transmission losses. Ferrule assemblies 5, each include an outer ferrule 25 receiving a reinforcing tube 26 and an inner ferrule 27 having slits 27a in optical fiber receiving ends and force-fitted into the reinforcing tube 26 with the core 24 received in a bore 31 of the outer ferrule as a sliding fit. Clamping collars, 9 and 10 are deformed to clamp cable reinforcing fibers 8 by assembly of the cover members 2,3. A one-piece, ganged sleeve member 130 and a retaining member 150 retain transducers 140 with leads trapped in grooves 138a,b and 139 for subsequent insertion in a main receptacle housing 110.
