A connecting terminal has a rectangular tube-like connecting portion including a bottom plate, and a first side plate. A movable contact strip is secured to the bottom plate at a base portion. The movable contact strip is bent into a shape of a mountain. An apex of the mountain constitutes a contact portion. Prior to the formation of the connecting portion, the movable contact strip is folded over the bottom plate. An elongated strip portion of the bottom plate is cut and bent inwardly to form a reinforcing strip. A rear end of the movable contact strip is connected to the bottom plate. A free front end of the reinforcing strip is urged against a lower surface of the contact portion. At a front end of the connecting portion, a guide strip is formed by folding back a front end portion of the bottom plate.

Connecting terminal

A connecting terminal has a rectangular tube-like connecting portionincluding a bottom plate, a first side plate not shown, a top plateand a second side plate. At a rear end of the top plate, there is formed a locking portionby folding a rear end of the top plate inwardly. A stabilizer portionprovided at one side of the second side plateis bent downwardly into a semicircular shape to extend downwardly with respect to the bottom plate.

A front endof a locking armprovided on a rear holderis inserted into a hole portionformed in a main housing, and the locking armis supported like as a bridge. The main housingis inserted into a hood portionof a cooperating housingand connecting terminals are connected to each other to establish the electrical connection. A locking clawformed on the locking armis once resiliently moved downward to pass through a locking clawof the cooperating housingand is then restored into an original posture to engage the locking clawwith the locking claw. Once the main housingis engaged with the cooperating housing, these housings could not be released accidentally.

Electrical connector having locking claw

In a connector terminal into which a cooperating male contact terminal can be smoothly inserted and a movable contact strip can be prevented from being buckled while a desired contact pressure can be attained, a connecting portionis formed into a substantially box shape by folding a bottom plate, side plates(is not shown) continuously extending from respective sides of the bottom plate and a top platecontinuously extending from one of the side plates. A movable contact stripis formed by folding back the top platearound a gently curved portioninto a resilient spring having an inverted triangular shape including a contact portionnear an inwardly bent middle portion of the movable contact strip. A holeis formed at an end portion of the movable contact stripinto which an engagement tipformed by folding a part of the top plateinwardly is inserted.

Connection terminal

A joint connector easy to construct and involving less fabricating cost. The joint connector comprises a housing,for accommodating a plurality of connecting terminals,in a rear-side portion thereof, a bus bar,formed out of an electrically conductive metal plate and accommodated in the housing,for jointing any individual ones of the connecting terminals,, a bus bar holder,for holding the bus bar,, and a front cover,mounted to the housing,in such a way as to cover the bus bar holder,. The bus bar holder,has a plurality of holes to be used for cutting the bus bar,to form an arbitrary circuit. The bus bar holder,and the bus bar,is mounted in the housing,so as to be movable in relation to the housing,in a direction orthogonal to the direction of the connecting terminals,being housed. When the front cover,is set in the housing,, it causes the bus bar holder,to be moved and the bus bar,to be jointed with connecting terminals

Joint connector

A connector including a reception housing which has four sector-shaped compartments defined by four radial partitions, and four sector-shaped end terminals are inserted into the four sector-shaped compartments from mutually orthogonal directions which are perpendicular to a direction in which an insertion housing is inserted into the reception housing. A number of male terminals are provided on each of the four sector-shaped end terminals, and a number of conductors of a plurality of flat cables are connected to the male terminals. On the insertion housing, a number of female terminals are provided each being connected to respective one of a number of electric wires. The male and female terminals are simultaneously coupled with each other by inserting the insertion housing into the reception housing.

Housing accomodating a plurality of flat cables

A connector including a reception housing in which a number of connecting terminals connected to respective conductors are accommodated, an insertion housing in which a number of second connecting terminals connected to respective conductors are accommodated, a holding housing for holding said reception housing, and a spring member arranged between the reception housing and the holding housing. When said insertion housing is inserted into said reception housing, said reception housing is pushed toward the insertion housing and first and second connecting terminals are coupled with each other by a restoring force of the spring means.

Connector

An electric connector including a first connector half having a plurality of terminals, a second connector half having a plurality of corresponding terminal and a pair of leaf springs secured to opposite side also of the first connector half for detachably coupling he first and second connector halves with each other. Each leaf spring includes a fitting portion, a bent portion, an unlocking portion, an intermediate portion, an end portion with a locking aperture, and a reinforcing portion having one end connected to a junction between the bent portion and the unlocking portion. The fitting portion is secured to the first connector half and an end of the reinforcing portion is urged against a side wall of the first connector half. When the second connector half is inserted into the first connector half, a locking projection formed on a side wall of the second connector half engages with the locking aperture for locking the first and second connector halves together. When the unlocking portion of the leaf spring is pushed toward the side wall of the first connector half, locking projection is disengaged from the locking aperture to release the connector halves. The reinforcing portion increases the resiliency of the leaf spring for preventing accidental unlocking and insuring a positive displacement of the end portion when unlocking.

Device for detachably coupling first and second halves of electric

An electric connector including a housing made of resin and having a plurality of cavities for receiving a plurality of terminals and a terminal retaining member made of resin and having a plurality of holes. When a rear portion of the housing is inserted into an opening formed in a front portion of the terminal retaining member, the housing and terminal retaining member are preliminarily coupled with each other in a first coupling mode in which the holes of the terminal retaining member are aligned with the cavities of the housing. After the terminals having electric wires connected thereto have been inserted into the cavities through the holes, the terminal retaining member is shifted in a direction perpendicular to a direction in which the terminals are inserted and then is further moved toward the housing to attain a second coupling mode. In the second coupling mode the terminals are engaged with portions of the terminal retaining member to prevent the terminals from being removed out of the housing.
