It has low insertion and extraction force, low contact resistance and high reliability. Hyperbolic wire spring jacks are mainly used in connectors for various key equipment.

[0003] At present, most of the wires in the wire spring holes on the market are connected manually, and a few use machine-connected wire clamping devices. During the wire clamping process, on the one hand, due to the thin wire specifications, it is difficult to be firmly clamped, and the wires are always entangled in the process of pulling the wires back and forth.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) The wire spring hole micro-clamping device clamps the wire through the wire column and the wire hole at the same time. When the outer shell mechanism is driven forward by the moving mechanism as a whole, the wire can be driven to be transported forward. When the device moves forward as a whole and makes the front end of the inner sleeve contact the object machine in front of it, the inner sleeve is forced to shrink toward the inside of the outer shell, so that the tension spring is stretched. When the inner sleeve moves backward as a whole, the front end inner diameter of the moving groove is larger, so that the clamping force between the moving groove and the front end of the clamping column is reduced. Therefore, when the device moves backward, the device can be moved without pulling the wire backward. In addition, through the elastic setting of the tension spring, when the device moves forward, the inner sleeve returns to its original position to re-clamp the wire and transport it. Through the design of the inner sleeve mechanism, the wire pulling can be automatically adjusted when the device moves forward and backward, so that the wire can be transported quickly and efficiently.

[0014] (2) The wire spring hole micro-clamping device can transport the five wires required by the device separately through the design of the wire column and the adapter column, and the clamping of the wire hole, so that the wires will not be tangled together during the transportation process. At the same time, through the symmetry of the structural design, the pulling force applied to the five wires during transportation is also different, and each wire is subjected to the same force, thereby effectively ensuring that the pulling force of the device on the wires is evenly distributed, and the wires can be protected from damage during the transportation process, thereby improving the quality of the finished product of the device.

[0035] Working principle:

[0036] The first step: the wire 403 is clamped by the wire column 401 and the wire hole 304 at the same time. When the outer shell mechanism 1 is driven forward as a whole by the moving mechanism, the wire 403 can be driven to be transported forward. When the device moves forward as a whole and makes the front end of the inner sleeve 203 contact the object machine in front of it, the inner sleeve 203 is forced to shrink toward the inside of the outer shell 101, so that the tension spring 202 is stretched. When the inner sleeve 203 moves backward as a whole, the front end inner diameter of the moving groove 208 is larger, so that the clamping force between the moving groove 208 and the front end of the clamping column 301 is reduced. Therefore, when the device moves backward, the device can be moved without pulling the wire 403 backward. And through the elastic setting of the tension spring 202, finally when the device moves forward, the inner sleeve 203 returns to its original position, clamps the wire 403 again and transports it. Through the design of the inner sleeve mechanism 2, the wire pulling can be automatically adjusted when the device moves forward and backward, so that the wire can be transported quickly and efficiently.

[0037] Step 2: Through the design of the wire column 401 and the adapter column 402, and the clamping of the wire hole 304, the five wires required to be transported by the device can be transported separately, so that the wires will not be entangled together during the transportation process. At the same time, through the symmetry of the structural design, the pulling force applied to the five wires during transportation is also different. The force applied to each wire is the same, which can effectively ensure that the pulling force of the device on the wire is evenly distributed, and the wires can be protected from damage during the transportation process, thereby improving the quality of the finished product of the device.
