摘要:
A socket connector for an electrical water heater, a plug connector, a connector combined with the socket connector and the plug connector, and an electrical water heater provided with the socket connector and the plug connector. The socket connector is provided with a movable insulated cover (6), which can enclose a socket hole (21,23) corresponding to an electrical contact (31) in a housing and can only be pushed away through a pushing hole (22). The plug connector is provided with a pushing pole (92), which can be inserted into the pushing hole to push the insulated cover away so as to open the socket hole corresponding to the electrical contact.

In invention relates to an electrical safety socket device for connecting appliances and devices to an electrical power line which prevents the occurrence of electric shocks thereby protecting the user by an inadvertent finger touch with the prongs of a plug or by a single-pole insertion. The electrical safety socket device comprises a plug receiving member (1 ) with means for establishing respective electrical conduction and non conduction states.

A miniature multi-polar electric plug which can prevent the male contacts from being placed unprotected all the time is provided. An electric plug (10) has a plug housing (1), male contacts (2) , a shutter (3) , a shell (4) , and a pair of compressed coil springs (5). The plug housing (1) has a header part (1a) and a frame part (1b). The header part (1b) protrudes from the frame part and has a mounting board (12) for mounting the male contacts (2) and the shutter (3). The compressed coil springs (5) move the shutter (3) to cover or uncover the male contact (2).

In a cooker it is undesirable that a given power outlet (1) and a given heating element (5) are energized at the same time. Instead of letting power supplied to the heating element (5) switch off the power outlet, the insertion of a plug (3) in the power outlet is used to switch off the heating element (5).

An electrical connector assembly 20 has a male connector 26 which mates to a female connector 28 thereby electrically engaging male terminal blades 24, locked to a male connector body 30, to female terminals locked to a female connector body 32. The blade of each male terminal project into a blind bore defined by a shroud 40 of the male connector body. Prior to mating of the electrical connector assembly, a retractable terminal blade stabilizer 22 is snap fitted into a blade alignment position 34 with the male connector via a dual fastening feature 58 constructed and arranged between the male connector body and the stabilizer, which prevents withdrawal of the stabilizer from the male connector and restricts further insertion of the stabilizer into the blind bore. When the stabilizer is in the blade alignment position, the tips of the blades are disposed within respective apertures 50 of the stabilizer and aligned to their respective female terminals and the remaining portion of the blades are shielded and thus protected from possible damage. During mating of the electrical connector assembly, the female connector body is press fitted to an axial projecting member 72 of the stabilizer, prior to the stabilizer moving out of the alignment position. Once the stabilizer is fitted to the female connector, continued mating causes the stabilizer to move out of the alignment position and into a seated position 36 as the blades travel through the apertures and into the female terminals of the female connector. When the electrical connector assembly is being unmated, the female connector, being tightly fitted to the stabilizer pulls the stabilizer, out from the seated position and back into the blade alignment position. Because the engagement of the stabilizer to male connector in the blade alignment position is stronger than the tight fit of the stabilizer to the female connector, continued un-mating of the female connector disengages the stabilizer from the female connector leaving the stabilizer in the blade alignment position as the female connector is completely separated from the male connector. The stabilizer is thus retracted and placed back into the alignment position for protecting and maintaining alignment of the terminal blades of the male connector.

An object of the present invention is to realize a highly reliable locking construction for a moving plate. A moving plate 50 movable between a retained position and a released position is accommodated in a receptacle 35 of a male housing 30. One receiving portion 52 is provided in a middle part of the front surface of the moving plate 50, and a latching portion 42 resiliently deformably projects from the back surface of the receptacle 35 such that the leading end of the latching portion 42 is engageable with the receiving portion 52 through an insertion hole 64 of the moving plate 50. A movement of the moving plate 50 at the retained position to the released position is prevented by the resilient engagement of the latching portion 42 and the receiving portion 52. At the start of the connection of two housings 10, 30, a releasing portion 22 provided on the front surface of a female housing 10 comes into contact with the latching portion 42 to disengage the latching portion 42 from the receiving portion 52.
摘要:
An electric connector (2, 2') adapted to be coupled to a complementary connector (3) along a first direction (A) and comprising an insulating casing (4) defining a number of cavities for respective electric terminals, a slide (16) fitted to the casing (4) to slide in a second direction (B) perpendicular to the first direction (A), and having cam grooves (22) for receiving respective engaging members (23) on the complementary connector (3) to produce a coupling movement of the connectors (2, 2'; 3) in the first direction (A) when the slide (16) is moved in the second direction (B) into a fully assembled position, releasable constraint means (40, 41, 62) for keeping the slide (16) partly connected to the casing (4), and an actuating lever (30) hinged, through a hinge portion (32), to the casing (4) about an axis (C), perpendicular to the first and second direction (A, B), to move the slide (16) into the fully assembled position; the hinge portion (32) has an angular coupling portion (35) for engaging the slide (16) and a free angular portion (63) for releasing the slide (16).
摘要:
An electric connector (2, 2') having an insulating casing (4) defining a number of cavities for housing respective electric terminals and having axes parallel to a first direction (A) in which the connector (2, 2') is coupled to a complementary connector (3); a slide (16) fitted to the casing (4) to slide in a second direction (B) perpendicular to the first direction (A), and having cam-type first engaging members (22) for receiving respective second engaging members (23) on the complementary connector (3) to produce a relative coupling movement of the connectors (2, 2'; 3) in the first direction (A) when the slide (16) is moved in the second direction (B) into a fully assembled position with respect to the casing (4); and retaining means (40, 41, 62) for keeping the slide (16) partly connected to the casing (4); the retaining means (40, 41, 62) being selectively deactivated when coupling the connector (2, 2') to the complementary connector (3).
