| 20100230160 | CRIMP TERMINAL, TERMINAL-PROVIDED WIRE, AND MANUFACTURING METHOD THEREOF - Provided is a technique of enabling high-compression crimping without breaking a crimp terminal while forming a recessed portion promoting a wire crimp portion of the crimp terminal to cut into a conductor in the wire crimp portion. The crimp terminal according to the invention includes a wire crimp portion, which is crimped to a conductor of a wire and includes a first crimp portion crimped to a base side of the conductor and a second crimp portion crimped to a tip end side. A recessed portion for promoting a cutting-in effect is formed in an inner surface of the wire crimp portion. A recessed portion formed in the second crimp portion is divided in a terminal width direction or is shallower than a recessed portion formed in the first crimp portion. Alternatively, the recessed portion is omitted and a recessed portion is formed only in the first crimp portion. | 09-16-2010 |
| 20100261391 | CRIMP TERMINAL, TERMINAL-PROVIDED WIRE, AND MANUFACTURING METHOD THEREOF - Provided is a technique of ensuring mechanical strength in a terminal-provided wire and lowering contact resistance between the wire and the crimp terminal, without greatly varying a crimp height of a crimp terminal onto the wire in an axial direction. A crimp terminal according to the invention includes a conductor barrel which is crimped to a conductor of a wire. The conductor barrel has an inner surface which closely contacts the conductor by bending. The inner surface has such a shape a surface thereof which closely contacts a tip end side part of the conductor inwardly projects beyond a surface thereof which closely contacts a base side part of the conductor, thus performing a higher compression of the tip end side part of the conductor than that of the base side part thereof by the bending. | 10-14-2010 |
| 20110003518 | TERMINAL CONNECTOR AND ELECTRIC WIRE WITH TERMINAL CONNECTOR - Rims of an opening of each recess form a parallelogram, and comprise two first opening rims that that are parallel to a first direction and two second opening rims that are parallel to a second direction. The first opening rims of each of the recesses that are aligned along the first direction are arranged on a straight line along the first direction. The second opening rims of each of the recesses that are aligned along the second direction are arranged on a straight line along the second direction. The recesses are formed by pressing a wire barrel with a die where a plurality of protruding parts are formed so as to correspond to recesses. | 01-06-2011 |
| 20110009014 | TERMINAL CONNECTOR AND ELECTRIC WIRE WITH TERMINAL CONNECTOR - A plurality of recesses are formed on a surface of a wire barrel where an electric wire is provided. In a state before the electric wire is crimped onto the wire barrel, at least one of sides comprising rims of an opening of each recess of a quadrangular shape is a crossing side crossing at an angle of from 85 degrees to 95 degrees to an extending direction. In a state before the electric wire is crimped onto the wire barrel | 01-13-2011 |
| 20110028054 | CRIMPING TERMINAL AND METHOD OF MANUFACTURING TERMINAL-PROVIDED WIRE - A crimp terminal whose crimp state can be easily evaluated and to provide a method of manufacturing a terminal-provided wire comprising the crimp terminal. The crimp terminal includes a pair of conductor barrels which are crimped onto a conductor of an electric wire. The conductor barrel has an outer surface provided with a crimp state indicator for evaluating a crimp level thereof. The indicator may be a mark so shaped that a position of an internal end of an outwardly exposed part thereof is varied in a terminal axial direction corresponding to the crimp level, or include a plurality of marks spaced in a direction perpendicular to the terminal axial direction. | 02-03-2011 |
| 20110045713 | CRIMP TERMINAL, TERMINAL-EQUIPPED ELECTRIC WIRE WITH THE CRIMP TERMINAL, AND METHODS FOR PRODUCING THEM - Provided is a crimp terminal designed to be crimped onto an end portion of an electric wire to form a terminal-equipped electric wire, achieving both of ensuring mechanical strength of the terminal-equipped electric wire and reducing a contact resistance between the electric wire and the crimp terminal. The crimp terminal comprises an electric contact section and an electric-wire crimp section to be crimped onto a conductor in the end portion of the electric wire, the crimp terminal being formed of a metal plate which has a copper-containing plate body and a tin-plating layer covering a surface of the plate body. In the crimp terminal, the tin-plating layer has a smaller thickness in a crimp surface region where the electric-wire crimp section is to make contact with the end portion of the electric wire is less than that in an electrical contact surface region where the electric contact section is to make contact with a counterpart terminal. | 02-24-2011 |
| 20110094797 | ELECTRIC WIRE WITH TERMINAL CONNECTOR AND METHOD OF MANUFACTURING ELECTRIC WIRE WITH TERMINAL CONNECTOR - An electric wire with terminal connector including an electric wire having a core wire including a plurality of wires and a female terminal connector including a wire barrel that is crimped onto the core wire exposed from the electric wire, the following steps are executed. The steps include a step of removing wire insulation covering an outer peripheral surface of the core wire to expose the core wire, a step of holding the exposed core wire with jigs provided in a pair and applying ultrasonic vibration to the core wire via the jigs, and a step of crimping the wire barrel so as to surround a part of the core wire to which the ultrasonic vibration is applied. | 04-28-2011 |
| 20120000069 | METHOD FOR MANUFACTURING ELECTRIC WIRE WITH TERMINAL - A method for manufacturing an electric wire with a terminal, includes crimping a barrel portion of the terminal onto a core wire constructed of metal wires and creating a crack in a metal oxide layer immediately before the crimping. The metal oxide layer is formed on a metal surface of the core wire. The creating of crack is accomplished by applying a mechanical force to the metal oxide layer. | 01-05-2012 |
