3results about How to "Avoid loose contact" patented technology

The utility model relates to the technical field of electrical connection spare, concretely relates to a socket plug sleeve with good contact effect, including bottom piece, the symmetric setting of bottom piece inserts piece, and the support section, the bending section and the contact section are formed to the insert piece through multiple times bending, and the contact section is provided with a plurality of notches parallel to the insertion direction, and the contact section is divided into a plurality of contact pieces. The contact piece includes the main piece and the vice piece of different width, and the inward side is bent to form the arc contact part. The utility model discloses through the design of piece by piece and makes each contact piece independent to fit the plug electric contact piece, and the point contact is converted into the multi-point distributed contact, and the line contact structure of arc contact part is matched, and the contact area is significantly expanded, and the contact resistance and the heating risk are reduced, and the poor contact problem caused by point contact is effectively solved, and the electric safety and reliability are improved.

The utility model relates to circuit breaker technical field discloses a kind of intelligent miniature circuit breaker with protection function, including circuit breaker main body, the upper end front side of circuit breaker main body is equipped with multiple thread grooves, thread groove equidistance distribution, the inner chamber of thread groove is provided with screw rod, the upper end rear side of circuit breaker main body is provided with terminal, and thread groove is in the accommodation slot of terminal with penetration.This utility model technical scheme can make protection plate cover in the upper of terminal, to protect terminal, avoid idle terminal to be corroded by external environment, and then influence subsequent terminal and wire connection, screw rod can be pressed tightly wire and terminal again, wire and terminal are limited, protection plate is pressed to the left again, and the clamping plate on protection plate is inserted into through slot, and the clamping plate is inserted into annular groove in positioning cap, and then the position of screw rod is limited, avoid the situation that terminal and wire loose contact is caused by screw rod loosening under the bumpy state.

The utility model relates to the field of power connection terminals, in particular to a plug female end for power connection of a new energy automobile, which comprises an insulating base and two conductive substrates, the conductive substrates are fixedly mounted in the insulating base, power connection pin groups are integrally formed on the conductive substrates, the power connection pin groups of the two conductive substrates are mutually symmetrical, and the power connection pin groups of the two conductive substrates are mutually connected. An auxiliary retaining plate is arranged at the ends, away from each other, of the two conductive substrates, the auxiliary retaining plate comprises a fixing part and an elastic extrusion part, the fixing part is fixedly connected with the surfaces of the conductive substrates, the elastic extrusion part extends to the outer sides of the power connection pin groups, and the elastic extrusion part is fixedly connected with the surfaces of the conductive substrates. The end, away from the fixing part, of the elastic extrusion part is tightly pressed on the outer side of the power connection pin set, a bidirectional clamping structure is formed through the two symmetrically-distributed conductive substrates and the integrally-formed power connection pin set, the elastic extrusion part of the auxiliary retaining plate is matched to continuously press the outer side of the pin set, and the radial clamping force on the male end is remarkably enhanced.
