The present disclosure discloses a receptacle housing and a receptacle. The receptacle housing has a housing body and a non-return element, wherein the housing body has a front side and a rear side in its axial direction. The housing body is formed with a mounting hole extending along an axial direction of the housing body to be arranged for accommodating a corresponding connecting terminal. The non-return element continuously extends from the housing body towards the rear side of the housing body to be axially block-fittable with the connecting terminal. By provision of the non-return element, the receptacle housing of the present disclosure may block the connecting terminal from retreating from the mounting hole on the housing body, so that a stable electrical connection between the connecting terminal and a mating terminal on a charging gun can be ensured.

The present disclosure discloses an electric protective cover for a receptacle and a receptacle. The electric protective cover comprises a cover body and a mounting portion. The cover body extends along a radial direction of the receptacle and is configured for covering a circuit board. An accommodating hole enclosed by an accommodating hole wall is disposed on the cover body to accommodate a connecting terminal. The mounting portion is disposed on the cover body to be mounted onto a receptacle housing. The electric protective cover according to the present disclosure may be readily and quickly assembled on the housing by means of the mounting portion and provide protection for the circuit board arranged on the housing and the elements on the circuit board by means of the cover body.

The present disclosure discloses a receptacle housing and a receptacle. The receptacle housing comprises a housing body and a hole wall. The hole wall continuously extends from the housing body along an axial direction of the housing body. The hole wall surrounds along a circumferential direction of the housing body to form a mounting hole for accommodating a corresponding connecting terminal. The hole wall is provided with a water draining through-hole. By providing the water draining through-hole in the hole wall, the receptacle housing according to the present disclosure may drain water accumulated in the mounting hole in such a circumstance as water drops are brought therein upon plugging a mating connecting terminal, and provide water draining channels by means of such an ingenious structural design that safety performance may be enhanced.

A waterproof connector (1) includes an accommodation recess (31) formed in a wire draw-out surface (26) of a housing (10) and configured to accommodate a ventilation film (63). A wire cover (50) is mounted on the housing (10) to cover the wire draw-out surface (26) and the accommodation recess (31). A wire bending space (54) inside the wire cover (50) is configured to bend wires (15) drawn out from the wire draw-out surface (26). A partition (56) is formed in the wire cover (50) and partitions between the accommodation recess (31) and the wire bending space (54) by contacting the wire draw-out surface (26) to cover an opening of the accommodation recess (31). Drainage portions (37, 38, 39, 40) are formed in a contact area between the wire draw-out surface (26) and the partition (56) and has a convexo-concave or stepped cross-sectional shape.

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 substrate unit includes a circuit board; a connector portion mounted on the circuit board; and a case that contains the circuit board. The case includes a lower case having an accommodation section opened upward and accommodating the circuit board. An upper cover covers the accommodation section of the lower case. An aperture is opened in a side wall of the case, allowing the connector portion to be fitted to a counterpart connector portion. The upper cover includes a ceiling portion having a board opposing region that opposes the circuit board accommodated in the accommodation section and an outer region is located outside of the board opposing region without opposing the circuit board; and guide grooves inclined from the board opposing region to the outer region. The guide grooves discharging the water droplets away from the circuit board.

A connector for plugging together with a counter-connector in a plug-in direction comprises a casing, a receptacle seal, and an oscillation absorber.
