A coupler for use in a liquid heater includes a male connector and a female socket connector. The male connector includes a connecting wall and an annular cylindrical wall formed around the connecting wall. The female socket connector comprises an end wall joined with the connecting wall of the male connector and a peripheral wall formed around the end wall and arranged perpendicularly to the end wall. The surface of the end wall joined with the connecting wall is gradually lowered from the center towards the periphery and is convex-hull shaped. The peripheral wall includes arced sections and gapped sections connected between two arced sections. When the male connector is coupled with the female socket connector, this allows the arced sections to be coupled with the annular cylindrical wall and forms no coupling between the gapped sections and the annular cylindrical wall.

A waterproof electrical connector includes a connector body and a waterproof cap. The connector body includes a mating island surrounded by a ring groove. The mating island defines a mating face and plural passageways. The passageways receive conductive terminals and penetrate through the mating face. A soft cushion is set inside the waterproof cap. The connector body includes a collar portion. The collar portion is higher than the mating face and forms an entrance cavity around the ring groove. When the cap covers the connector body, the soft cushion penetrates into the entrance cavity to press and seal the mating face.

An implantable blood pump system is disclosed herein. The implantable blood pump system includes an implantable blood pump, a controller coupled to the blood pump, a connector receptacle, and a connector insert. The connector receptacle can include a plurality of contacts, and a following surface. The connector insert can be received within the connector receptacle to couple a plurality of insert contacts with the plurality of contacts of the connector receptacle. The connector insert can include walls defining a follower receptacle that can receive a portion of the following surface when the connector insert is in a desired alignment with respect to the connector receptacle, and a cam surface that can engage with the following surface to bias the connector insert to the desired alignment with respect to the connector receptacle when the connector insert is inserted into the connector receptacle.

A cover structure that includes a base that is attached to a circuit substrate of an electric connection box on which an electrical component is mounted, the base being used as a receptacle for a cable that is to be electrically connected to the electrical component; and a housing that houses the circuit substrate.

A male connector (1) includes terminal-equipped wires (10), a male housing (20) having a male terminal holding portion (21) and a rubber plug accommodating portion (32). A one-piece rubber plug (50) and a holder (60) are accommodated in the rubber plug accommodating portion (31). The rubber plug accommodating portion (31) includes a surrounding wall (33) that surrounds the rubber plug (50) and the holder (60). The surrounding wall (33) includes a lower wall (33B) below the rubber plug (50) and the holder (60). Drainage holes (36) penetrate through the first lower wall (33B), and each has a water inlet (36A) open on an inner side of the lower wall (33B) and a water outlet (36B) open on an outer side. The holder (60) has a contact surface (61A) configured to contact the rubber plug (50), and the water inlets (36A) are arranged right below the contact surface (61A).

A connector part of a subsea connector adapted to be mated with a second part of the subsea connector by application of a mating force. The connector part has at least a first contact configured for engagement with a respective second contact of the second connector part for establishing a connection. The connector part further includes a flushing mechanism having a chamber filled with a medium and one or more fluid passages providing a flow connection from the chamber to an area adjacent to the first contact. During mating of the first connector part with the second connector part, the flushing mechanism is actuated by the mating force and medium is expelled from the chamber and is directed towards at least one of the first contact or the second contact so as to flush the first contact or the second contact, respectively, during mating.

An on-vehicle device has a device box accommodating a device body; a terminal block attached to an upper wall of the device box; and a wire harness electrically connected to the device body through this terminal block. The terminal block adopts a drain structure, and this drain structure is provided with: the upper wall of the device box; a housing body attached to the side of an outer surface of the upper wall; a drain outlet passing through a bottom wall of the housing body; and a drain ditch formation portion for forming a drain ditch from this drain outlet to the outside of the housing body. In the drain ditch formation portion, an outer surface of the bottom wall is formed so as to be separated from the outer surface of the upper wall by a dimension of a gap where a capillary phenomenon occurs.

A bus bar terminal includes an electrode connection portion that connects electrode terminals of power storage elements to each other, and a wire connection portion that is to be connected to an electrical wire, and guide portions are provided between the electrode connection portion and the wire connection portion, the guide portions guiding adhered liquid so as to fall to a position separated from the wire connection portion.

A connector (1) into which a mating connector (female connector 101) is fittable from front includes a tubular receptacle (40) having a forwardly open fitting opening (50) capable of accommodating the mating connector (101) fit through the fitting opening (50). A drainage recess (70) penetrate in a direction perpendicular to a front-rear direction at a position retracted from the fitting opening (50) in the receptacle (40). Partitioning ridges (60) are at positions retracted from the fitting opening (50) and project in a direction intersecting the front-rear direction from the receptacle (40). A front end (first rib end 61A) of some partitioning ridge (first rib 61) is coupled to and flush with a back wall (72) of the drainage recess (70).
