Abstract

A manual machine for attaching an insulation displacement connector (10) has housing stoppers (34A,34B) for positioning it on a rest (33), a housing holder (35) for holding the connector on the rest, and a set block (36) disposed near the rest in order to position electric wires (11) at their ends or middle portions. The machine further has a wire holder (37) near the housing holder (35) so as to guide and hold the wires at a given pitch, and a wire stopper (38) pivoted to the set block (36) so as to swivel between an active position close to this block and an idle position remote from it. The wire stopper (38) has a collision portion (61) on which the wire ends (11) will impinge to be aligned one with another, and a biasing portion (63) that will urge the wires'"'"' middle portions towards the set block (36).

Claims

1. A manual machine for attaching an insulation displacement type connector comprising:

a base plate incorporated in a machine body and capable of sliding therein to reciprocate between an inoperative home position and a working position for attaching the connector,

a connector rest fixed on the base plate,

a housing stopper for positioning the connector lying on the rest,

a housing holder for pressing the connector against the connector rest so as to hold the connector in place,

a set block disposed adjacent to the rest such that a plurality of electric wires are capable of being positioned selectively with respect to their free ends or with respect to their middle portions,

a wire holder disposed adjacent to the housing holder such that the wires to be attached to the connector are capable of being guided and held in place, while being arranged side by side at a prescribed given pitch,

a wire stopper that is pivoted to the set block so as to swivel between an active position close to the set block and an idle position remote therefrom, and

the wire stopper having a collision portion on which the wires will impinge at their free ends to be aligned one with another, and a biasing portion that will urge the wires at their middle portions towards the set block.

2. A manual machine as defined in claim 1, wherein the collision portion is formed as an array of flat wall zones of a front face of the wire stopper, and each wall zone is defined between adjacent two of notches carved side by side at the given pitch in the front face.

3. A manual machine as defined in claim 1, wherein the housing stopper is composed of a fixed shoe and a movable shoe so that the connector laid on the connector rest are protected from becoming out of order in position in the direction of the given pitch, the fixed shoe is secured to one, of opposite side ends of the connector rest, with the movable shoe facing the fixed one and capable of sliding along a front face of the set block, and the movable shoe has a vertical ear protruding therefrom for selective engagement with one of vertical grooves that are formed side by side at the given pitch in the set block front face, such that the movable shoe is capable of being set at any desired incremental position correspondingly to the number of poles of the connector.
