Background

In the current wire harness manufacturing field, wires are a process method for forming permanent electrical connection between wires by pressure. In recent years, as the requirements of electronic products in the aerospace field on reliability and environmental adaptability are higher and higher, the quality of the electronic products cannot be guaranteed by the traditional connector welding technology, so that the traditional connector welding technology is replaced by the crimping technology with higher reliability, and crimping becomes a termination method which is widely used in the aerospace field.

The existing wire crimping process is mainly completed by crimping a coaxial connector through crimping pliers, wherein the type is 1553B coaxial connector, an outer conductor is a cup-shaped contact piece coated outside an inner conductor contact pin, the tail end of the outer conductor is a wiring part, and a cavity for plugging a wire core is formed in the outer conductor. After wire stripping is carried out on one end of the electric wire, the electric wire core can be inserted into the cavity, and the wiring part of the outer conductor is pressed by the pressing claw of the pressing clamp to form an indentation, so that the wiring part of the outer conductor can be fixedly contacted with the electric wire core and cannot be displaced. However, because the application range of the 1553B coaxial connector is small, the application range of the 1553B coaxial connector is almost only in the aerospace field, and the 1553B coaxial connector belongs to a very rare contact type even in the same type of products, although a special crimping pliers can be used for crimping the 1553B coaxial connector, in the aspect of positioning equipment of hydraulic pliers, a special positioner matched with the special crimping pliers is not used in the market nowadays, so that positioning calibration of the 1553B coaxial connector is difficult to achieve, transmission performance is affected if the indentation pressed by the crimping pliers is too deep, and wire cores are not firmly crimped and are very easy to break away from an outer conductor if the indentation pressed by the crimping pliers is too shallow.

Therefore, the conventional 1553B coaxial connector is difficult to perform positioning calibration when being crimped.
