Supporting pieces () on side surfaces of a waiting-side connector () are insertable into supporting grooves () of a casing (). Contact projections (F,R) are on one outer wall surface () of each supporting piece near the upper end and bottom ends. A squeezable projection () is on an outer wall surface () opposite from the outer wall surface () where the contact projections () are provided. The squeezable projection () has a substantially triangular cross section and contacts a wall surface (A) of the supporting groove () as insertion of the supporting piece () into the supporting groove () progresses. A tip of the squeezable projection () is squeezed at a final stage of the insertion to engage the supporting piece () with the supporting groove (). Accordingly, the waiting-side connector () is supported in the casing () without shaking.

Connector supporting structure and a squeezed amount calculating method

A joint connector has wire holders ( ) that project in a wire draw-out direction from wire draw-out portions ( ) of housings ( ) where wires (W) connected with terminal fittings ( ) are drawn out. The wires (W) are held tightly between the inner surfaces of the opposite wire holding portions ( , , ). Holding projections ( ) project from the inner surfaces of the wire holding portions ( , , ) toward the opposite surfaces, so that the wires (W) can be so held as not to come out while being partly squeezed.

A ground terminal ( ) has a fixing portion ( ) formed with a bolt hole ( ) for receiving a bolt (B) for fixing the fixing portion ( ) to a mount member (A), a wire-connecting portion ( ) for fixing a wire, and a coupling portion ( ) between the fixing portion ( ) and the wire-connecting portion ( ). The coupling portion ( ) is formed with a pointed fracture groove ( ) extending in widthwise direction and having an apex ( ) symmetrically disposed the coupling portion ( ). The ground terminal ( ) can be easily fractured and separated with the apex ( ) of the fracture groove ( ) as a fracture starting point by lifting the wire connecting portion ( ) up to bend the ground terminal ( ).

Ground terminal and method of forming it

A wire harness includes sharable housings Ha to Hg which enable insertion of terminals either insulation displacement terminals Ta and crimp terminals Tb; a first sub-harness formed by inserting the insulation displacement terminals Ta into the sharable housings Ha to Hg; a second sub-harness formed in the same manner as the first sub-harness ; and an after-insertion electric wire WR having the crimp terminals Tb crimped at both ends. The crimp terminals Tb of the after-insertion electric wire WR is inserted into a sharable housing H, thereby connecting the sub-harnesses and . The crimp terminals Tb are used for only terminal hardware to be connected to the after-insertion electric wire WR which requires adhesion strength between an electric wire and terminal hardware. The majority of remaining terminal hardware pieces are embodied as the insulation displacement terminals Ta.

Wire harness

A shielding terminal ( ) is accommodated in a cavity ( ) of a housing ( ) in a connector ( ) and is doubly locked by a lock ( ) of the housing ( ) and by a ground terminal ( ). A recess ( D) is formed in a shielding shell ( ) of the shielding terminal ( ) during the formation of a locking claw ( B) for locking a dielectric element. The recess ( D) is narrower than the lock ( ). Hence, the lock ( ) neither enters nor gets caught by the recess ( D) during insertion of the shielding terminal ( ) into the cavity ( ). Therefore, an insertion resistance of the shielding terminal ( ) can be reduced.

Shielding terminal and a connector provided therewith

A connector having an improved force for locking a shielding terminal. The connector ( ) has a housing ( ) and a ground terminal ( ) is mounted into a shielded casing (C) after a shielding terminal ( ) is partly locked in a cavity ( ) of the housing ( ) is partly locked by a locking portion ( ) and then fully locked by touching pieces ( ) of the ground terminal ( ). The connector ( ) can doubly lock the shielding terminal ( ). Hence, the locking force for locking the shielding terminal ( ) can be improved.

Connector and method for mounting a connector

A connector ( ) has an improved operability by reducing an insertion resistance of a shielding terminal. The connector ( ) has a housing ( ) and a ground terminal ( ). Contact pieces ( ) of the ground terminal ( ) are movable between a retracted position and a contact position and can be locked at the respective positions. A shielding terminal ( ) can be inserted into the housing ( ) at the retracted position where the contact pieces ( ) and the shielding terminal ( ) do not interfere with each other. Thus, an insertion resistance of the shielding terminal ( ) can be reduced. Therefore, an assembling operability of the connector ( ) can be improved.

Connector and a method for mounting a connector

A method is provided for connecting a terminal fitting and a flat conductor to achieve a high contact pressure between the terminal fitting and a conductive path. A FFC ( ) has an insulation sheet ( ) adjacent the end stripped to expose a conductor ( ). The FFC ( ) is inserted between first and second squeezing plates ( ) of a terminal fitting ( ). Complimentary recessed/projected portions ( ) are formed on the outer surfaces of a pair of upper and lower press dies ( ) for pressing the terminal fitting ( ). The terminal fitting ( ) is pressed by the press dies ( ). Thus, the FFC and the terminal fitting ( ) are pressed together into a single unit and the squeezing plates ( ) are formed into a zigzag configuration.

A terminal fitting (T) has a pair of crimping pieces ( A, B) that extend up from opposite side edges of a bottom wall ( ), and are crimped into connection with a wire (W) placed on the bottom wall ( ). The crimping pieces ( A, B) are offset to each other in the longitudinal direction of the wire (W). Restricting portions ( A, B) are formed on the bottom wall ( ) and restrict a lateral displacement of the wire (W) against pushing forces acting on the wire (W) from the crimping pieces ( A, B) in directions normal to the longitudinal direction of the wire (W) while the crimping pieces ( A, B) are being crimped into connection with the wire (W).

Terminal fitting with crimping pieces and portions for restricting wire movement

A cramping terminal fitting is provided to maintain a satisfactory contact state with a wire without applying plating again after shaping the terminal fitting by a press. The terminal fitting includes insulation displacement contact (IDC) portions ( ) into which a wire can be pushed. Each IDC portion ( ) is comprised of a contact portion ( ) formed by embossing side walls ( ) in such a manner as to have a triangular cross section, and cutting blades ( ) formed by bending long pieces ( ) and short pieces ( ) to have a triangular cross section. Further, guide portions ( ) for guiding the wire to the IDC portions ( ) are provided above the cutting blades ( ). Since the contact portions ( ) remain plated, a contact state with the wire can be satisfactorily maintained.

Terminal fitting and a production method

A connector has a housing ( ) with cavities ( ) for accommodating both crimping and insulation-displacement terminal fittings ( ). Locks ( ) extend into the cavities ( ) to elastically engage the terminal fittings ( ). A retainer mount opening ( ) extends through an outer wall of the housing ( ) and communicates with the cavities ( ), and a retainer ( ) is mounted in the opening ( ) for doubly locking the terminal fittings ( ). Connecting portions ( ) of the same shape are provided at the front of the terminal fittings ( ). The height of insulation-displacement portions ( ) is shorter than that of the connecting portion ( ) in the insulation-displacement terminal fitting ( ), and terminal locks ( ) of the retainer ( ) engage with steps ( A) at the rear of the connecting portions ( ). The retainer ( ) can be pushed to a full locking position after the terminal fittings ( ) are mounted with the housing ( ) to redundantly lock the terminal fittings ( ) in the cavities ( ).

However, since the corresponding pairs of locking portions and receiving portions are provided in intermediate positions, a sufficient locking force can be ensured.

Connector

An insulation-displacement terminal (T) includes opposed side walls ( ) and a wire-receiving space therebetween. Insulation-displacement portions ( ) project from the side walls ( ) and into the wire-receiving space. Each insulation-displacement portion ( ) has two bases ( ) that project from longitudinally spaced positions on the corresponding side wall ( ). A blade ( ) has two panels folded from the respective bases ( ) and projecting further into the wire-receiving space. The folded blades ( ) cut sharply into the resin coating (Wa) of a wire (W) urged into the wire-receiving space, and the bases ( ) resist pulling forces on the wire (W). Therefore, a loose movement of the wire (W) in its longitudinal direction can be prevented.

Insulation-displacement terminal fitting
