3results about How to "Reliable electrical contact" patented technology

The invention provides an electrical parameter measuring device and method for a rock and soil sample. The device comprises a device base, a horizontal holder assembly, a pressure assembly, an AB power supply electrode assembly, a top end M and N spring electrode assembly, a lateral MN probe electrode assembly and an electrical parameter measuring module. Two horizontal clamp assemblies are symmetrically arranged on the left side and the right side of the device base, pressure assemblies are installed on the horizontal clamp assemblies and abut against the AB power supply electrode set, the top end M and N spring electrode assemblies are installed at the two ends of the middle of the device base and stretch across the device base, and the lateral MN probe electrode assembly is installed on the rear side of the device base. And the electrical parameter measuring module is connected with an electrode column on the device base. The technical problems that in a traditional method, clamping force is difficult to control, contact is poor, current distribution is uneven, the process is opaque, data cannot be post-processed and the like are solved, and universalization, high precision and repeatable measurement of rock and soil samples are achieved.

The utility model discloses a terminal and connector. The terminal comprises: a terminal body, comprising a matching part in the shape of a dovetail clamp, used for clamping a matching terminal inserted; and an elastic clamp, assembled to the matching part, used for increasing the clamping force of the matching part clamping the matching terminal, the terminal body is a copper piece or a copper alloy piece for conducting current, and the elastic clamp is a steel piece. In the utility model, the terminal has simple structure and low cost. In addition, in the utility model, the elastic clamp made of steel can increase the clamping force of the matching part of the terminal body clamping the matching terminal, so that the matching part of the terminal body and the matching terminal can be reliably and stably electrically contacted.

The utility model relates to the technical field of electric connection, in particular to a wire end connector, which comprises an insulating seat body, a power connection assembly, a locking assembly and a wiring assembly, a fixed cavity and a wiring cavity are arranged in the insulating seat body, are respectively arranged at two ends of the insulating seat body and are communicated with each other, and the locking assembly is arranged in the fixed cavity. One end of the power connection assembly is arranged in the fixed cavity, and the other end of the power connection assembly extends to the outside of the insulating seat body to form a connecting plug; the wiring assembly is arranged in the wiring cavity and is electrically connected with the power connection assembly; the locking assembly comprises a locking plug-in cavity, a locking supporting table, a locking pressing plate and a locking buckling plate. The locking plug-in cavity is formed in the insulating base and located on one side of the fixing cavity. According to the utility model, the locking object is reliably locked, so that accidental pulling-out caused by shaking and the like in the vehicle-mounted use process is prevented, a stable guarantee is provided for connection between vehicle-mounted equipment, and the reliability and the safety of the whole system are improved.
