A method of manufacturing an electrical wire connecting structure in which a terminal having a tube-shaped portion and a conductor portion of a covered electrical wire are crimped at the tube-shaped portion, and the tube-shaped portion has a conductor crimping portion corresponding to the conductor portion, and a cover crimping portion corresponding to a cover portion of the covered electrical wire, the method comprising the steps of a) forming the tube-shaped portion, b) inserting the covered electrical wire into a corresponding space, c) crimping a welded portion of the conductor, and d) compressing the cover crimping portion.

The invention is related to a crimp tool having an adjustable cam for accomplishing precision machining of a connector with a cable. The adjustable cam is provided at one of the handles of the crimp tool and is configured to prevent a moving handle of the crimp tool from moving beyond the adjustable cam so as to allow a user to adjust the pivot range of the moving handle, which controls the extent of the movement of a machining block in a machining portion of the crimp tool.

Under compression by molds (31a, 31b), a wire (25), a covered area (27), and a crimping portion (5) are compressed and their cross-sectional areas decrease. Here, A1 is the cross-sectional area of the wire (25) after compression. That is, A1 is the sum of the cross-sectional area of the each strand after compression. Also, 131 is the cross-sectional area of the covered area (27) after compression. In the present invention, the compression rate for the wire (25) is set between 50% and 80%. Also, the compression rate for the covered area (27) is set between 40% and 90%. The amount of compression by the molds (31a, 31b) is set so that the compression rates are within these ranges. In the present invention, the compression rate is calculated by: (cross-sectional area after compression)/(cross-sectional area before compression). That is, 80% compression rate means that the cross-sectional area has decreased by 20% due to compression. That is, the relationships of 80%(A1/A0)50% and 90%(B1/B0)40% are satisfied.

The press-fitting device has: a base; a rear surface plate; and a vertical operation section and mounts PF terminals having a shoulder section and a PF section to the member to be mounted. Provided on the vertical operation section are: an insertion path wherein a continuous PF terminal body formed by consecutive PF terminals is inserted; a movable feeding means that feeds the continuous PF terminal body along; a dividing means that divides the continuous PF terminal body into individual PF terminals; and a mounting means that mounts the PF terminals to the mounting member. A fixed feeding means is fixed to the rear surface plate in a static state relative to the vertical operation section, and restricts continuous PF terminal body movement that is in conjunction with the vertical operation section. The PF terminals are mounted to the mounting member by the vertical movement of the vertical operation section.

A manufacturing method of a crimping terminal includes a terminal supply step of supplying the crimping terminal to a crimping position with a wire by a terminal supply device, the crimping terminal including a terminal connection portion, a wire connection portion to be crimped onto the wire, and a joint portion linking side walls of the terminal connection portion and the wire connection portion, a support step of supporting a bottom portion of the crimping terminal supplied to the crimping position by a first mold, a crimp step of deforming the wire connection portion while relatively moving toward the first mold, and crimping the wire connection portion onto the wire by a second mold, and a regulation step of regulating a width of the joint portion so as not to be wider than a width of the terminal connection portion, by sandwiching the joint portion from both sides in a width direction when the second mold crimps the wire connection portion by a regulation portion.

An electric wire with a terminal includes an electric wire, and a crimping terminal including an electric wire connection portion crimped by being wound around a core and a cover of the electric wire, a diameter expansion portion which contains a water stop member covering a tip end portion of the core and sealing a gap between the core and the electric wire connection portion is provided in an end portion of the electric wire connection portion on a tip end side of the core, and a sectional area of the diameter expansion portion is greater than a sectional area at a portion on the base end side of the core with respect to the diameter expansion portion.

A pneumatic crimping tool has a crimping axis, along which a contact and a cable end can be introduced into a crimping opening, wherein a plurality of punches can be introduced into the crimping opening radially to the crimping axis. An adjusting wheel is provided, which surrounds the crimping axis, the radial crimping depth being adjustable by rotating the adjusting wheel.

A crimping hand tool used for crimping a coaxial cable and a coaxial terminal together is provided. The crimping hand tool includes a first body, a second body pivoted to the first body, a first linking body having a first end pivoted to the second body and a second end, a second linking body having a third end pivoted to the first body and a fourth end, a third linking body having a fifth end and a sixth end, a moving assembly, and a crimping assembly, wherein the second, the fourth, and the sixth ends are pivoted coaxially. The moving assembly is pivoted to the fifth end and slidably coupled to the first body along an axial direction. The crimping assembly is disposed on and moves along with the moving assembly to crimp the coaxial cable and the coaxial terminal together.

The present invention relates to a measuring device for determining the height of a crimp in a crimp connector to a conductor, such as in a cable lug or ferrule. The Exmore CRIMPING MEASURING DEVICE is a crimp height and crimp width measuring system, developed for highly precise measuring of crimp contacts. The invention is characterized by changes in the blade as used in a micro-metric measuring device. The measuring device according to the invention comprises a measuring knife comprising a resilient tool, further comprising a plate-shaped tool which is placed centrally in the measuring knife and which is placed perpendicularly to the orientation of the measuring knife. Measurement is performed manually and independent of any operator-related influences by way of centering unit. The Exmore CRIMPING MEASURING DEVICE simplifies the crimp height measurement process resulting in faster measurement time and improved consistency, acquired measured values can be read off, transferred via the serial interface or optionally printed.

A crimping machine having a multiplicity of magazines for contact elements which are transportable to a transfer position via a conveyor device. A component to be crimped is then brought from the transfer position into a crimping position by means of a transport device. This transport device is assigned to all of the storage arrangements.
