Embodiment Construction
[0036] The connection between the shielded twisted pair and the connector contact is a blow-welding connection. The butt joint of a pair of shielded twisted pair includes the connection of two pairs of core wires and the connection of a pair of shielded layer conductors. The core wires are connected by double ends. The two pairs of core wires are connected with the contact pair assembly 1 including two double-ended contacts 13, and the shield conductors are connected with copper tubes 16. The connection method is a blow-welding connection of contact pieces + solder strips + heat-shrinkable tubes. The two pairs of core wires are connected by one blow welding. The connection between the core wires and the shielding layer are operated step by step. The insulating layer between it and the copper pipe 16 is a heat-shrinkable tube 14 and an insulating sheath 17 .
[0037]In terms of design structure, use a contact pair assembly 1 with a blow-welded terminal structure to connect the ...

The invention provides a wire connector and an assembling method of a shielded twisted pair. The wire connector comprises a contact pair subassembly, a shielding tube subassembly and pressing sleeve subassemblies, wherein after the wire connector and the shielded twisted pair are assembled and soldered by wires, the shielding tube subassembly is located outside the contact pair subassembly; shielding layer conductors cover two ends of the shielding tube subassembly; two pressing sleeve subassemblies are located on the shielding layer conductors at two ends of the shielding tube subassembly; and the shielding layer conductors are tightly pressed among the pressing sleeve subassemblies and the shielding tube subassembly. According to the wire connector disclosed by the invention, a wire connecting process is simple, feasible and obvious, the welding quality is reliable, the wire connection is short and the flexibility of a cable is good; and the connection cost of the shielded twisted pair is low and the environmental resistance is good.
Description
technical field [0001] The invention relates to a connector for permanent connection between ends of shielded twisted pairs in network wiring and an assembly method thereof. Background technique [0002] With the rapid development of modern communication technology, the network wiring structure responsible for data transmission functions is becoming more and more complex. The wiring quality of shielded twisted pair terminals between system interfaces directly affects the transmission performance of the entire network. In network wiring, higher requirements are put forward for the connection reliability, cable flexibility, installation efficiency, volume and weight of shielded twisted pair connectors. [0003] At present, there are two connection methods for shielded twisted-pair wires: one is to use ordinary crimping type connectors, crimping paired pins and jacks on two pairs of core wire terminals, and crimping the shielding layer on a metal sheath Realize the connection ...
