An electrical connection assembly includes an installation cylinder, a cable, a terminal, a temperature sensor, and a heat shrink tube. The installation cylinder has a front end and a rear end opposite each other in an axial direction of the installation cylinder. The cable passes through the installation cylinder and has a conductor end extending from the front end of the installation cylinder. The terminal has a connection end electrically connected to the conductor end. The temperature sensor is in thermal contact with the connection end and has leads passing through the installation cylinder. The heat shrink tube is fitted and heat shrunk onto the rear end of the installation cylinder, the cable, and the leads led out from the rear end of the installation cylinder. The heat shrink tube achieves sealing between the cable, the leads, and the installation cylinder. The temperature sensor detects a temperature of the terminal.

A position retaining member is adapted to be inserted into a connector housing and adapted to be moved between a final lock position and a pre lock position. The position retaining member includes a cantilever part and a pressing part. When the position retaining member is in the final lock position, the cantilever part is adapted to be pressed against an elastic buckle of the connector housing to hold the elastic buckle in a locking position engaged with a protrusion of a mating housing of a mating connector. When the position retaining member is in the pre lock position, the pressing part is adapted to press the elastic buckle to an unlocking position separated from the protrusion of the mating housing, allowing the connector housing to be pulled out from the mating housing.

An elastic terminal ferrule includes an annular body, a limit structure formed on the annular body, and a mating limit structure formed on the annular body for mating with the limit structure. When the annular body is in a natural state without radial expansion, the limit structure and the mating limit structure are spaced apart from each other in a circumferential direction. When the outer diameter of the annular body is expanded to a predetermined value, the limit structure and the mating limit structure abut against each other in the circumferential direction to prevent further radial expansion of the elastic terminal ferrule.

A bulkhead connector comprises a connector housing, a nut member and a self-locking structure. The nut member is removably fitted to the connector housing to secure the bulkhead connector to a target plate body. An outer surface of the connector housing is formed with an outer thread, and an inner surface of the nut member is formed with an inner thread. The self-locking structure includes a groove formed in the outer surface of the connector housing, and an elastic locking element arranged on the nut member. Upon a thread fit between the inner thread of the nut member and the outer thread of the connector housing, at least a portion of the elastic locking element engages with the groove to form a self-locking of the thread fit.

A connector includes a housing having a top wall and a bottom wall, a pair of side walls, and a front opening and a rear wall. Two rows of terminals having soldering ends extend backward from the rear wall of the housing. The connector includes two pressing plates including an upper pressing plate disposed on an upper side of the soldering ends of the upper row of terminals and a lower pressing plate disposed on a lower side of the soldering ends of the lower row of terminals. The two pressing plates slide from a pre-assembly position in which the soldering ends of the terminals are not pressed to a final assembly position in which the soldering ends of the terminals are pressed on the circuit board by the pushing of the circuit board.

A terminal includes a tubular body and a welding portion. The tubular body has a front tubular portion mating with a mating terminal and a rear tubular portion joined with an injection-molded seal. The welding portion is connected to a rear end of the tubular body and welded to a conductor of a power transmission member. The terminal is a one-piece stamped copper terminal. The nickel plating layer is formed on an entirety of the terminal. The nickel plating layer is a base plating layer of the terminal. The terminal has a mating zone at the front tubular portion, an injection molding zone at the rear tubular portion, and a welding zone at the welding portion. A silver plating layer is formed on the nickel plating layer in the mating zone. A tin plating layer is formed on the nickel plating layer in the injection molding zone.

A seal includes an elastic body having a through hole receiving a terminal with a cable and an inner sealing rib extending circumferentially around the through hole and interference fit with the cable to form a seal with the cable. An inner contour line of the inner sealing rib is elliptical. A major axis and a minor axis of the inner contour line respectively correspond to a major side and a minor side of a rectangular section of the terminal.

A terminal includes a cylindrical body, a crimping portion, a plurality of resilient pieces, and a sleeve. The crimping portion is disposed at an end of the cylindrical body and crimps a wire onto the terminal. The plurality of resilient pieces extend from an other end of the cylindrical body and electrically connect a mating terminal inserted between the resilient pieces. The sleeve is sleeved on outer sides of the cylindrical body and the resilient pieces. The sleeve has at least one set of protrusions. Each protrusion protrudes from a side wall of the sleeve towards the cylindrical body. Each protrusion abuts against the cylindrical body and aligns with each other in a circumferential direction of the sleeve adjusting a coaxiality between the sleeve and each of the cylindrical body and the resilient pieces.

An assembly includes a terminal and a sleeve. The terminal has a main part extending in an axial direction. The sleeve is assembled onto the main part. The main part is formed with a first anti-rotation structure. The sleeve is formed with a second anti-rotation structure. The first anti-rotation structure and the second anti-rotation structure cooperate with each other and prevent the sleeve from rotating around the main part.

A conductive terminal assembly includes a conductive terminal, a sleeve, and a locking structure. The conductive terminal has an end with an insertion portion. The insertion portion has an insertion cavity receiving a mating terminal. The sleeve is sleeved on an outside of the insertion portion. The locking structure fixes the sleeve and the insertion portion together. The locking structure has a protrusion protruding from one of a side wall of the insertion portion and a side wall of the sleeve towards the other. The protrusion is engaged with another of the side wall of the insertion portion and the side wall of the sleeve to suppress a movement of the sleeve relative to the insertion portion.
