Abstract
Abstract A method of and apparatus for crimping a ferrule part of an electrical connector to a wire end is disclosed for use with connectors wherein a portion of the contact part of the connector extends beyond the base of the U-section ferrule part in the opposite direction to that in which the U-arms of the ferrule part extend.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
228 words
An apparatus for crimping a ferrule part of an electrical connector to a wire end, the apparatus comprising means for intermittently feeding a strip of connectors along a predetermined path to position successive leading connectors at a crimping zone, a die and an anvil each having cooperable crimping surfaces for crimping the ferrule part of the connector to a wire end at the crimping zone, and each being movable between the crimping zone and a retracted position remote from the crimping zone, the direction of movement of the anvil being at substantially 90* to the feed path of the connectors, means for maintaining the die and the anvil in their respective retracted positions while the connectors are being fed, means for advancing the anvil from its retracted position to the crimping zone to position its crimping surface adjacent the base of the ferrule part, after the connector has reached the crimping zone, to support the base during the crimping operation, means for advancing the die from its retracted position to the crimping zone after the anvil has been advanced, to cause the crimping surfaces of the die and the anvil to cooperate to crimp the ferrule part to a wire end when operatively inserted in the ferrule part and means for severing the connector from the strip after the ferrule part has been crimped to the wire end.
Claim 2
Independent Claim
228 words
An apparatus for crimping a ferrule part of an electrical connector to a wire end, the apparatus comprising means for intermittently feeding a strip of connectors along a predetermined path to position successive leading connectors at a crimping zone, a die and an anvil each having cooperable crimping surfaces for crimping the ferrule part of the connector to a wire end at the crimping zone, and each being movable between the crimping zone and a retracted position remote from the crimping zone, the direction of movement of the anvil being at substantially 90* to the feed path of the connectors, means for maintaining the die and the anvil in their respective retracted positions while the connectors are being fed, means for advancing the anvil from its retracted position to the crimping zone to position its crimping surface adjacent the base of the ferrule part, after the connector has reached the crimping zone, to support the base during the crimping operation, means for advancing the die from its retracted position to the crimping zone after the anvil has been advanced, to cause the crimping surfaces of the die and the anvil to cooperate to crimp the ferrule part to a wire end when operatively inserted in the ferrule part and means for severing the connector from the strip after the ferrule part has been crimped to the wire end.
Claim 3
Dependent Claim
90 words
An apparatus as claimed in claim 1, in which the anvil is supported on a movable anvil slide to which is attached a slide stop for limiting the advance movement of the anvil slide, a spring maintaining the slide stop in a first position corresponding to the retracted position of the anvil, and a piston and cylinder arrangement engaging the slide stop and operable to advance the slide stop against the action of the spring into a second position corresponding to the position of the anvil in the crimping zone.
Claim 4
Dependent Claim
35 words
An apparatus as claimed in claim 2, in which in the second position, the slide stop engages a member which initiates operation of a die support means to move the die towards the crimping zone.
Claim 5
Dependent Claim
56 words
An apparatus as claimed in claim 1, in which a strip clamp is provided for clamping the strip when a connector is at the crimping zone, the strip clamp being movable from a first retracted position in which the strip is free to move, to a second clamping position in which it engages the carrier strip.
Claim 6
Dependent Claim
53 words
An apparatus as claimed in claim 4, in which the strip clamp is engaged by a spring to bias the strip clamp towards the first position and a piston and cylinder position is provided for moving the strip clamp from the first to the second position against the biasing action of the spring.
