A sleeve () is a hollow cylindrical member provided in a shield terminal (), and pressable by a wire barrel () by being arranged between an insulating portion () and a shield portion () of a shielded cable (). A convex portion () shaped to bulge radially outward over an entire circumference is provided at an intermediate position of the sleeve () in an axial direction. The convex portion () is crushed and elongated by the wire barrel () of an outer conductor terminal (). The insulating portion () can be prevented from being excessively compressed.

Sleeve and shield terminal manufacturing method

A shield terminal () includes an inner conductor terminal () and an outer conductor terminal () surrounding the inner conductor terminal (). The outer conductor terminal () has a pull-out opening () through which an inner conductor connecting piece () of the inner conductor terminal () is pulled toward a circuit board (). The outer conductor terminal () includes outer conductor connecting pieces that face the pull-out opening () and that include first and second outer conductor connecting pieces () located on both sides across the inner conductor connecting piece () in a plan view and a third outer conductor connecting piece () that faces the inner conductor connecting piece () in a direction orthogonal to an arrangement direction of the first and second outer conductor connecting pieces () at a position between the first and second outer conductor connecting pieces () in the arrangement direction.

Shield terminal and shield connector

An outer conductor terminal () includes a body () surrounding an outer periphery of an inner conductor terminal () and having a rear opening and a lid () for closing the opening of the body (). Body-side locks () are provided on side surfaces of the body (). The lid () has side portions () for covering the side surfaces of the body (). The side portions () are provided with front abutting portions () contacting the body-side locks () from the front. The lid () has rear abutting portions () contacting the body-side locks () from behind to sandwich the body-side lock portions () between the front abutting portions () and the rear abutting portions () and to hold the lid (). The body-side locks () include contact portions () that contact the rear abutting portions () with resilient forces.

Outer conductor terminal and shield connector

A shield terminal () includes an inner conductor terminal (), an outer conductor terminal (), a dielectric () and a capacitor serving as an electronic element (). The outer conductor terminal () surrounds the inner conductor terminal () and is connected to a shield portion () of a shielded cable (). The dielectric () is arranged between the inner conductor terminal () and the outer conductor terminal (). The electronic element () includes a core connecting portion () to be connected to a core () of the shielded cable () and an inner conductor connecting portion () to be connected to the inner conductor terminal (). In the shield terminal (), an insulating short circuit preventing member () is arranged between the core connecting portion () and the outer conductor terminal ().

Shield terminal

A board connector includes fixing members () to be mounted into a connector housing (). Each fixing member () includes a plate-like housing mounting portion () to be arranged along a surface () of the connector housing () and a board fixing portion () connected to the housing mounting portion () and to be fixed to a surface of a circuit board () by soldering. The housing mounting portion () includes a flat plate () near the circuit board (), a flat plate () distant from the circuit board () and a bent portion () between the respective flat plates () and bulging in a plate thickness direction with respect to the flat plates (). The bent portion () is provided over an entire width of the housing mounting portion () in a plate width direction between the flat plates ().

Board connector

An inner conductor terminal () is made of a metal plate and includes tubular first terminal portion () and second terminal portion () each having an opening end. A bent portion () links the first and second terminal portions () and covers the respective opening ends of the first and second terminal portions () by facing the openings. A tab () projects from an end of the first terminal portion () opposite to the opening end, and a lead () projects from an end part of the second terminal portion () opposite from the opening end. The inner conductor terminal () includes two side panels () projecting from the second terminal portion () to be located at both sides of the bent portion () and covering a clearance between the bent portion (), the first terminal portion () and the second terminal portion () from both sides.

Inner conductor terminal and shield terminal

A shield terminal () includes an inner conductor terminal () and an outer conductor terminal () surrounding the inner conductor terminal () and having a tubular fitting portion (to which a mating outer conductor () is fit. The tubular fitting portion () includes butting edges () to be butted against each other on both circumferential edge parts (A,B), fixed contact point portions () formed to have an embossed shape in a butting-side half circumference portion (C), the fixed contact point portions () contacting the mating outer conductor (), and resilient contact portions () formed by cutting and raising parts of an opposite-side half circumference portion (C) on a side opposite to the butting-side half circumference portion (C), the resilient contact portions () resiliently contacting the mating outer conductor ().

A board connector () includes a receptacle () fittable to a mating connector and fixing members () for fixing the receptacle () to a circuit board (). The receptacle () is in the form of a rectangular tube and has a pair of side walls () facing each other in a width direction and a bottom wall () and a ceiling wall () facing each other in a height direction. At least either the side walls () or the bottom wall () include(s) mounting recesses () for mounting the fixing members () within a wall thickness between an inner side surface and an outer side surface of the receptacle ().

A board connector includes a plate-like fixing member () to be mounted in a housing () and including a board fixing portion () to be fixed to a circuit board () by solder. At least the board fixing portion () of the fixing member includes a plurality of plate pieces (A,B) arranged to face each other in a plate thickness direction. Plating layers () are formed on plate surfaces of the plate pieces (A,B) and plating drip layers () continuous with the plating layers () are formed on end surfaces of the plate pieces (A,B) intersecting with the plate surfaces.
