An electrical connector includes a metal locknut having an inner thread, an orifice defined and a retaining portion, an elastic cylindrical casing having a mounting base for fastening to the retaining portion of the locknut, a core tube inserted into the locknut and the cylindrical casing for receiving the center conductor and inner dielectric insulator of a coaxial cable and having a barbed flange for engaging the braided metal wrapper of the coaxial cable, a first tubular wall and a packing portion connected for engaging into the mounting base of the cylindrical casing, and a barrel mounted on the cylindrical casing and having a contracted inner wall portion adapted for compressing the cylindrical casing.

The invention discloses a pull rod type inclined cutting machine convenient to transport. The pull rod type inclined cutting machine is characterized by comprising a base, a worktable, a support, a rocker arm assembly, a sliding rod assembly, a machine body, a drive device, a control device and a saw web. A rotation table of the worktable is arranged on the base in a rotating mode and is provided with a notch groove from front to back. The support is fixedly arranged in the back of the upper side of a supporting part of the base. The rocker arm assembly comprises a rocker arm, and the rocker arm is arranged at the rear end of the rotation table in a rotating mode and can turn to the left side or the right side. The machine body is arranged on the rocker arm through the sliding rod assembly. The drive device is a brushless direct current motor, a stator is fixedly arranged on the machine body, the axis of the stator is horizontally arranged from left to right, a brushless motor outer rotor assembly is arranged on the machine body through a corresponding bearing assembly in a rotating mode after a drive shaft of the brushless motor outer rotor assembly penetrates through the stator from right to left, and the corresponding part of the stator is located in a motor case. The saw web is detachably fixed to the drive shaft of the brushless motor outer rotor assembly of the drive device. The drive device is electrically connected to the control device.

The invention discloses a low-infrared radiation exhaust system for a high-speed assault boat, which comprises a first exhaust pipe, an injector, a muffler assembly, a second exhaust pipe, a compensator and an outlet pipe connected in sequence; The wall pipe is composed of the pipe mouth of the double-wall pipe close to the muffler assembly, which is lower than the mouth of the double-wall pipe far away from the muffler assembly. The double-wall pipe is provided with a nozzle socket, and a nozzle holder is installed on the nozzle socket. The invention adopts seawater to cool the exhaust gas, which improves the sound-absorbing performance, reduces the discharge of harmful components in the exhaust gas into the atmosphere, and increases the safety on board. The seawater injection also reduces the exhaust volume flow rate, so the weight and size of the exhaust system can be reduced; the installation method of the system is designed ingeniously to avoid the deformation of the system exhaust pipe and other pipelines during the installation process or the damage during installation.
