Description
- The invention relates to a 2-gang socket-outlet, comprising a body of insulating material, a mounting plate, having the body attached thereto, metallic terminal units, including first connectors fitting for contact with the prongs of electric plugs and second connectors intended for contact with electric wires, and a housing section, constituting a cover or a case which conceals an interior of the socket-outlet, the socket-outlet interior comprising at least the body and the terminal units, a separate insulating element being attached to the body, the insulating element covering the terminal units along with the connectors thereof, such that, once installed, the socket-outlet interior is a screen-protected single unit without the housing section.
- In prior known socket-outlets, the housing section forms a segment of the shroud. Child protectors are generally also attached to the housing section. This sets its specific limitations to the modifiability of a housing section in terms of materials and shapes. Safety aspects must also be considered when interchanging housing sections. Live socket-outlets may also exist at a working site (against regulations) due to various stages of construction and electrical installation processes. This may result in so-called passing contact electric shocks from exposed first connectors.

- Fig. 25
- shows the child protection element of
figs. 23 and24 in an assembly view, and - Fig. 25a
- shows the same as
fig. 25 in a view from the opposite direction. - The main components in a 2-gang socket-outlet of the invention are a
housing section 1, a mountingplate 2, abody 3 of insulating material, which is attached to the mountingplate 2, metallicterminal units 4, anearth terminal unit 9, aninsulator 6, which in the present embodiment constitutes at the same time a part of a child protection element,child protectors 7 and acover 8 for the child protector, as well as adisengagement member 10. - Aside from the
housing section 1, the above components make up an interior 5 assembled for a single package, which houses all technical features of the socket-outlet and whichinterior 5, once installed, is screen-protected without thehousing section 1. Thus, thehousing section 1 is replaceable, e.g. for reasons of appearance (colour, shape, surface quality, etc.), or capable of creating diverse product variations (product for concealed installation, surface-mounted product, etc.). - Each of the above-mentioned main components or elements will now be described in more detail as follows.
- The
body 3 illustrated infigs. 11-14 is provided with two elongated recesses 3.4 with expanded ends for receiving subsequently describedterminal units 4, such that theterminal units 4 and anearth terminal unit 9 to be placed therebetween are spaced and electrically insulated from each other. Thebody 3 has its bottom side edges provided with holes 3.1 for bringing electric wires diagonally from below to connectors. By virtue of the conical expansion of the body's inclined holes 3.1 and 3.9 and the inclination of other surfaces as well, it will be possible to use a simple mould without expensive side draw pins. Preferred inclination angles at the components' mating surfaces enable installation of the components directly from above. Thebody 3 has its sides provided with lugs 3.2 for fastening screws and/or engagement claws. Thebody 3 is provided with vertical, open-topped channels or recesses 3.3 for receiving clamping brackets 8.3 (Fig. 24 ) of a child protector's cover. In the middle of thebody 3, between the spaces 3.4, is adisengagement member 10, having its ends 10.2 in the form of a flexible tongue provided with cogs 10.1 extending into spaces 3.5 present at the ends of the body, which receive the earth terminal unit's 9 cable connectors 9.4, 9.6 (Fig. 19 ). Thus, by bending the tongues 10.2 from the bottom side (Fig. 14 ), tabs 9.5 present at the ends of a connector spring 9.4 are forced by the cogs 10.1 through openings 9.8 (Fig. 19 ), thus enabling the disengagement ofwires 11.Fig. 11a visualises the disengagement member's 10 extended skirts 10.3, which are positioned between the earth terminal unit andother terminals 4 and improve electrical separation therebetween. - The
terminal unit 4 depicted infigs. 15-18 comprises first connectors 4.1, fitting for contact with the prongs of electric plugs, and second connectors 4.2 intended for contact with electric wires. Theterminal unit 4 consists of two elements, namely a connector spring 4.3 and a single plate member, constituting a terminal body and having a deflection 4.7 of 180° for providing connectors 4.1 between the deflected plate sections. A number of additional deflections 4.8 are used for providing connectors 4.2 for electric wires and a closed circle which is locked by engagements 4.10. The connectors 4.2 are configured as spring connectors by fitting theunit 4 with a connector spring 4.3, which has four pieces of deflected spring connectors 4.4. The ends thereof are provided with tabs 4.5 to be placed behind openings present in the connectors 4.2. These tabs or claws 4.5 can be actuated by cogs or protrusions 8.1 present at the ends of the flexible tongues 8.5 of a child protector'scover 8, visualised infigs. 24 and25 , for opening the spring connectors 4.2, 4.4. The connectors 4.2 are secured in a desired angular position between a deflected member 4.9 (Fig. 15 ) and the engagement lug 4.10. The connector spring 4.3 is fastened to the terminal body by riveting through its apertures 4.6 with rivets made by drawing from the terminal body. - The
earth terminal unit 9 shown infig. 19 consists of three different (four in total) elements, which are depicted infigs. 20-22 . Two pieces of cradle guards 9.1 offig. 20 are attached to each other by means of a grounding bridge 9.3 offig. 22 , which are riveted to the guards 9.1 by rivets 9.7 drawn from the very material of the cradle guard and therebetween is secured a connector spring 9.2 which, together with angularly deflected ends 9.6 of the grounding bridge 9.3, constitutes self-clamping spring connectors 9.4, 9.6 forearth conductors 11 which can be inserted in the connectors diagonally from below the socket by way of holes 3.9 (Fig. 14 ) present in the gable edge of the body's 3 bottom. Support lugs 9.9 deflected from the guard 9.1 support a deflected connector end of the spring 9.2. -
Figs. 23-25 illustrate a child protection element, including aninsulator 6 visualised infigs. 25 and25a . Thisinsulator 6, together with acover 8 of the child protector, conceals theterminal units interior 5 is screen-protected without thehousing section 1. In addition, the side of theinsulator 6 to be set against thebody 3 is provided with ribs 6.5 for improving electrical separation between theterminal units 4 and theearth terminal unit 9. On top of theinsulator 6 are spring-loadedchild protectors 7 and the child protector'scover 8 provided with receptacles 8.2 for thechild protectors 7. Thechild protector 7 has its aperture 7.2 fitted with a spring 7.1, which bears against a tab 8.4 emerging from thecover 8 and present in the aperture 7.2. Thechild protectors 7 operate on a conventional seesaw principle and are only able to move against the force of the spring 7.1 when the prongs of an electric plug function through the socket holes simultaneously and in a balanced fashion on the child protector's 7 inclined surfaces. - The cogs 8.1 present at the ends of the cover's 8 flexible tongues 8.5 engage in slots 6.1 present in the insulator's 6 inclined side extensions 6.2, through which the cogs 8.1 are pressable against tabs 4.5 of the terminals' 4 connector springs, as described above in connection with the connector spring of
fig. 15 . The claws of the insulator's 6 vertical protrusions 6.6 engage in recesses 8.6 present in the cover's 8 side edges to secure the child protection element for a single component used in final assembly. In the process of final assembly, the vertical brackets 8.3 (4 pieces in total) guide the assembly work by penetrating into the body's 3 vertical channels 3.3. Theinsulator 6 is provided with recesses 6.3 for the passage of the brackets 8.3. Together with end claws 8.7 (4 pieces in total), the brackets 8.3 also clamp theinterior 5 for a single assembly.Figs. 11 and12 illustrate bosses 3.7 at the body's 3 gables to engage with the claws 8.7. Theinsulator 6 and thecover 8 are also provided with holes for the passage of the housing section's 1 fastening screws 13, such that these screws can engage with the threads thereof in the bores of the body's 3 sleeves 3.6 (Fig. 12 ). Screen-protected insulation can be provided also without a child protector by means of an insulating element corresponding to thecover 8 or substituting for thecover 8 and theinsulator 6. - The
insulator 6 and the child protector'scover 8 are of course provided with through-holes for the prongs of an electric plug and the cradle guards 9.1. - The child protector's
cover 8 is provided with collar-like bosses 12, encircling the through-holes for the prongs of an electric plug and extending into the holes of thehousing section 1. Thus, the material used for thehousing section 1 need not satisfy such electrotechnical standards which are required of a material in contact with or supporting live metal components. This also works in favour of the objective of the invention that variousreplaceable housing sections 1 can be used for creating diverse product variations, in which theinterior 5 remains the same.
