Abstract:
A method is provided for ensuring and/or checking the quality of a crimping using a crimping machine for crimping a cable with a contact sleeve and using a first optical sensor for detecting and/or recording first image data of the contact sleeve and using an evaluation electronics system. The method includes detecting the first image data of the contact sleeve by the first optical sensor; carrying out, via the evaluation electronics system, a first comparison of the first image data of the first optical sensor with first reference data of a predetermined contact sleeve; checking the first comparison for the presence of a predetermined first criterion; and, if the predetermined first criterion is satisfied, outputting a first signal. The detection of the first image data and the first comparison and the checking for the first criterion and the output of the first signal are carried out before the cable is crimped with the contact sleeve. A crimping machine suitable for carrying out the above method is also provided.
Abstract:
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.
Abstract:
The invention is related to a crimping tool. The crimping tool includes a connection rod having one end pivotally connected to the first handle and the other end of the connection rod pivotally connected to a crimp section. A first screw rod is disposed at the second handle of the crimping tool. The first screw rod drives the connector which leads the first handle to displace. The movement of the first handle leads a connection rod to displace. As a result, the position of a crimp section on the first handle can be adjusted.

Abstract:
A terminal crimping device includes crimp tooling including an anvil and a ram movable toward the anvil with a crimp zone being defined between the anvil and the ram configured to receive a wire and a terminal configured to be crimped to the wire by the crimp tooling. An ultrasonic transducer is coupled to at least one of the anvil and the ram that receives acoustic signals sent through the wire and terminal. A crimp quality module receives signals from the ultrasonic transducer. The crimp quality module determines a crimp height of the terminal based on the acoustic signal received by the ultrasonic transducer. Optionally, the crimp height may be determined based upon a transmission time of the acoustic signal from a transmitting transducer to a receiving transducer. The crimp height may be determined based upon a speed of sound transmission coefficient of the terminal and the wire.
Abstract:
The present invention relates to a positioning device for positioning an element to be crimped in a crimping tool, for example a wire end sleeve or an electrical connecting plug. The invention further relates to a crimping tool for crimping a connecting element to be situated in a pressing axis. To allow the element that will be crimped to be brought into the pressing axis, the positioning device has a retaining unit for retaining, about its periphery, the element that will be crimped. The retaining unit has a retaining opening which encompasses the pressing axis coaxially. The positioning device further permits the positioning of the element that will be crimped within the pressing axis, in order, in particular, to ensure the necessary insertion depth of the element to be crimped in the crimping tool. For this purpose, the positioning device of the invention has an axial stop, with which the position in the pressing axis of the element to be crimped can be defined. According to the invention, the size of the retaining opening of the retaining unit can be adjusted coaxially in relation to the pressing axis. The size of the retaining opening can therefore be increased and decreased, with a center axis of the retaining opening coinciding with the respective pressing axis. Moreover, the axial stop is displaceable along the pressing axis, allowing different distances from the crimping tool to be realized.
Abstract:
An applicator ram includes a ram body configured to hold crimp tooling, and a ram adaptor coupled to the ram body. The ram adaptor is configured to be coupled to a terminator ram. The ram adaptor includes an adaptor hub having a hub chamber configured to receive a ram post of the terminator ram. A latch mechanism is movably received in the hub chamber. The latch mechanism is movable between a latched position and an unlatched position. The latch mechanism is configured to engage the ram post in the latched position. The latch mechanism allows the ram post to be released from the hub chamber in the unlatched position. An adaptor stud extends from the adaptor hub and is configured to be coupled to the applicator ram.
Abstract:
In a method for inspecting a conductor crimping portion of a crimping terminal, a laser displacement meter is disposed on a final stage of the terminal manufacturing line, and an upper surface of the flat-shaped bottom plate of the conductor crimping portion of a conveyed crimping terminal is measured, thereby acquiring, as an inspection result, data pertaining to at least one of items; namely, a width of the interior surface of a bottom plate, a width of the serrations, and a depth of the serrations.
Abstract:
A wire-processing apparatus has grippers feeding a wire to processing stations for producing wire end connections. A holder is used to inspect the wire end connection, wherein the linear movement of the grippers is used for the automated inspection of the wire end connection by applying a pull out force along a longitudinal axis of the wire while the holder is retaining the connection.
Abstract:
An apparatus for measuring a metal terminal includes a crimping unit which crimps core wire crimping piece portions to a core wire of a sheathed electric wire to form a core wire crimping portion and crimps sheath crimping piece portions to a sheath portion of the sheathed electric wire to form a sheath crimping portion, a gripping member which grips the core wire crimping portion in a direction perpendicular to an extending direction of a base plate portion of the metal terminal, and a measuring unit which measures a dimension of the core wire crimping portion and a dimension of the sheath crimping portion. A height of the sheath crimping portion is measured in a direction intersecting with or parallel to the direction of gripping of the core wire crimping portion in a state that the core wire crimping portion is gripped in a direction perpendicular to an extending direction of the base plate portion.
