Description

Treatment device for the shielding layer at the end of the shielded cable

technical field

The invention relates to a processing device for a shielded cable, in particular to a processing device for a shielding layer at the end of a shielded cable.

Background technique

Shielded cable is a commonly used connecting wire. Referring to Figure 1, the structure of shielded cable is generally: the core is covered with an insulating layer in the middle, and the wire core is wrapped with a metal wire braided shielding layer made of metal wires. , the metal wire braided shielding layer is the sheath. Referring to Figure 2, for some shielded cables, in order to enhance the shielding effect, an aluminum foil shielding layer is added between the wire core and the metal wire braided shielding layer.

Before using a shielded cable, it is usually necessary to process the shielding layer at its end. Specifically, referring to Figure 3, it is necessary to separate the braided metal wire shielding layer at the end from the core, and separate the separated wires that constitute the shielding layer. Twist the metal wire bundles into a strand. If there is an aluminum foil shielding layer, it is necessary to peel off the aluminum foil shielding layer from the wire core.

At present, machines are used to do the above processing. The processing method of this machine is: first, the shielded cable to be processed is transmitted to the stripping device through the cable transmission device, and the skin of the shielded cable is stripped from the shielded cable by the stripping device. Then, the stripped shielded cable is sent to the wire brushing device by the cable transmission device, and the metal wire in the metal wire braided shielding layer is brushed by the wheel brush of the wire brushing device, so that the metal wires braided together are brushed. The brush is scattered and bent at a certain angle to separate from the wire core; finally, the shielded cable that has been brushed and separated by the metal wire is sent to the twisting device through the cable transmission device, and the metal wire is twisted by the twisting device. The brushed, separated bundles of metal wires in the wire braid shield are twisted into a single strand. If it is necessary to deal with the aluminum foil shielding layer, add a stripping device to peel off the aluminum foil shielding layer.

When the above-mentioned machine is processing, it uses the wheel brush of the wire brushing device to brush the metal wire braided shielding layer, so that the metal wire is scattered and bent to achieve the purpose of separating from the wire core. This separation method is for brushing and sweeping. Untangling wires that are braided together is often time consuming, especially when encountering tightly braided wire shields.
