Such crimping device consists of a conventional crimping device (10) with a movable punch (14) and a moving base (12), each acting on half of a matching set of crimping dies (16,16). A pre-stress gauge is set up to measure the force applied to the crimped connector (20), and a linear transfer device (30) measures the position of the punch (14) during crimping as the punch (14) moves down and begins crimping. The force as expressed by the stress gauge is monitored until it reaches a predetermined value. Monitoring continues until the force reaches zero, at which point the position of the punch (14), as expressed by the linear transfer device (30), is converted into the crimping height.

Claims

1. The method for calculating the high crimping (F) of the connector (20) crimped onto element (22) is made by taking advantage of a crimping tool consisting of a press (10) with a base (12) and a nut (14) arranged to move relative to each other, opposite each other. The base (12) and nut (14) each act to bring halves of the crimping die assembly (16,18) together, which consists of (a) placing the connector (20) and element (22) in the crimping position within the crimping tool, and (b) causing at least one of the base (12) and nut (14) to move relative to each other, so that the die assembly (16,18) grips and crimps the connector (20) onto the element (22). The method is characterized by (c) during which step (b) determines that the actual crimping process has begun. and subsequently, the force acting on the said connector is monitored as the force recedes from the predetermined value to zero. As the force reaches zero at the same time, it determines (72) the distance of movement between the connector segments (44,46) of the said mold set (16,18). This distance is the height of the said crimp (F).

2. The method according to claim 1 is such that the determination (70) that the crimping process has begun includes monitoring the forces present on the said connector until those forces reach the required value.

3. The method under claim 2, in which the crimping tool consists of a means for generating both the force signal that represents the force, which is generated by the connector (20), and the displacement signal that represents the displacement between the connector segments (44,46) of the die set (16,18), where step (c) is characterized by (c 1) a comparison (70) which compares the force signal to the first reference signal that represents zero, and (c 2) when the force signal equals the first reference signal, a comparison (72) which compares the displacement signal to the second reference signal that represents the desired crimping height, and if the difference between these signals exceeds a predetermined value (74), a rejection signal is generated.

4. The method according to claim 3 is such that the said crimping tool (10) consists of memory (76) and procedure (c2) including the accumulation of such strong signals into the said memory (76).

5. The method under claim 4 is characterized by step (d), which is a step that converts the signal to the said travel distance into a form that can be read by a person.

6. The connector clamp (20) is placed on element (22) which is assembled with a press (10) with a base (12) and a crimping arm (14) arranged to move relative to each other in opposite directions. The base (12) and crimping arm (14) each move half of the matching die assembly (16,18). The device for determining the crimping height (F) of the connector (20) that is crimped on element (22) has the following characteristics: (a) a control path (24,26) for determining and monitoring the force applied to the connector (20) during crimping, and (b) a travel path (30) for determining the travel distance between the interlocking parts (44,46) of the die assembly (16,18) when the applied force is equal to zero.

7. The instrument under claim 6 is such that the path for the travel (30) is composed of a linear differential transformer (32) with the stator and armature and a path for the first signal that indicates the relative positions of the stator and armature, where one of the stator and armature is attached to the base (12) and the other to the striker (14).

8. The instrument under claim 7 is such that the control path (24) is established when a second signal representing the force applied to the connector (20) is generated during the crimping of the connector, and this second signal is continuously compared to a zero reference signal until the second signal equals zero.

9. The instrument under claim 8 is of the nature that the control path (24) is a strain gauge (24) and the instrument contains a path (78) for performing the mobile communication to the control panel (Clause 9, page 3, figure 6).
