Abstract

The invention relates to a 2-gang socket-outlet, comprising a body (3) of insulating material, a mounting plate (2), having the body (3) attached thereto, metallic terminal units (4), including first connectors (4.1) fitting for contact with the prongs of electric plugs and second connectors (4.2) intended for contact with electric wires, and a housing section (1), constituting a cover or a case which conceals an interior (5) of the socket-outlet. The socket-outlet interior (5) comprises at least the body (3) and the terminal units (4) and usually also a child protector. The body (3) is fitted with a separate insulating element (6, 8) for covering the terminal units (4) along with the connectors (4.1, 4.2) thereof, such that, once installed, the socket-outlet interior (5) is screen-protected without the housing section (1). This enables manufacturing simple housing sections (1) in diverse materials, colours and shapes, which include neither child protectors nor other technology. <IMAGE>

Double socket

The invention relates to a double socket comprising an insulating body, a mounting plate to which the body is attached, metal connector elements having first plugs suitable for contact with the pins of plugs and second plugs for contacting electric wires, and a cover part forming the inner part of the socket. or housing when the interior of the socket includes at least a housing and connector elements.

10 In known sockets, the cover part forms part of the contact protection. Child protectors are also usually attached to the cover part. This puts its own limitations on the flexibility of the cover part in terms of materials and shapes. Safety factors must also be taken into account when replacing cover parts. On site, there may also be live electrical outlets without a cover (though not permitted) due to different construction and electrical work stages. In this case, the so-called. touch electric shocks from the open first connectors.

Each of the above main components or elements will be described in more detail below.

The body 3 shown in Figs. 11-14 is provided with two elongated recesses 3.4 extending at its end 10, which receive the connector elements 4 to be described in greater detail so that the connector elements 4 and the earthing terminal element 9 between them are spaced electrically apart. The frame 3 has holes 3.1 at the side edges of the base, from which electrical conductors can be inserted obliquely into the terminals. Due to the conical expansion of the holes 3.1 and 3.9 of the frame skews 15 and the skewing of other surfaces, a simple mold can be used without expensive side cores.

Due to the advantageous angles of contacting surfaces of the parts, the parts can be installed directly from above.

The connector element 4 shown in Figs. 15-18 includes first connectors 4.1 for contacting the pins of the plugs and second connectors 4.2 for contacting the electrical wires. The connector element 4 is made of two parts, namely a connector spring 4.3 and a single plate piece forming the connector body 5 with a 180 ° bend 4.7 to form the connectors 4.1 between the bent plate parts. With a plurality of additional bends 4.8, terminals 4.2 are formed for the electrical wires and a closed periphery which is locked by the engagements 4.10. The couplings 4.2 are formed as spring couplings by attaching to the element 4 a coupling spring 4.3 with four bent spring couplings 10 4.4. Their ends have protrusions 4.5 which are located behind the openings in the connectors 4.2. These protrusions or cams 4.5 may be actuated by the cams or protrusions 8.1 at the ends of the flexible tabs 8.5 of the child protection cover 8 shown in Figures 24 and 25 to open the spring terminals 4.2, 4.4. The terminals 4.2 are supported in the desired angular position between the bent portion 4.9 (Fig. 15) and the tar-15 projection 4.10. The connector spring 4.3 is fixed to the connector body by riveting its holes 4.6 with rivets made by pulling the connector body.

The grounding terminal element 9 shown in Fig. 19 consists of three different (four total) parts shown in Figs. 20-22. Two kappa-.

This insulation part 6, together with child protection cover 8 * · · '! •, · * 7 * 115090 5 is fitted with a non-contact protective cover 1. In addition, the side facing the body 3 of the insulating part 6 is provided with ridges 6.5 which improve the electrical connection between the connector elements 4 and the grounding connection element 9. the difference. On top of the insulating part 6 there is a spring-loaded child protection 7 and a child protection cover 8, 5 having spaces 8.2 for receiving the child protection 7. A spring 7.1 disposed in the opening 7.2 of the child restraint 7 leans against the tongue 8.4 from the cover 8 which is located in the opening 7.2. The child protectors 7 operate on the known rocking board principle and can only move against the force of the spring 7.1 when the pins of the plug plug act simultaneously and balance) through the slotted holes on the oblique surfaces of the child protection 7.

The tabs 8.1 at the ends of the flexible tabs 8.5 of the cover 8 engage the openings 6.1 in the sloping side projections 6.2 of the insulating section 6 through which the tabs 8.1 can be pressed against the cam 4.5 of the connector springs of the connectors 4 as previously described in FIG. The claws of the vertical projections 6.6 of the insulating part 6 engage the notches 8.6 on the side edges of the cover 8, binding the child protection element to one of the parts used in the final assembly. In the final assembly, the vertical pins 8.3 (4 in total) guide the assembly: ·,: as the assembly protrudes into the vertical groove of the frame 3. The insulating part 6 has notches 6.3: 20 for penetrating the pins 8.3. The pins 8.3 also, together with the ends::: nails 8.7 (4 pcs. In total), lock the inner part 5 into one unit. Figures 11 and 12 show protrusions engaging with claws 8.7 • Il »i '·': 3.7 at the ends of the body 3. The insulating part 6 and the cover 8 also have holes for passing through the cover screws 13 of the part 1 so that these screws can engage with 25 threads in the inner holes of the sleeves 3.6 of the body 3 (Fig. 12). The non-contact insulation can be formed by an insulating element corresponding to the cover 8 or replacing the cover 8 and the insulating part 6: * [': without child protection.

The cover 8 of the child cover has sleeve-like projections 12 surrounding the through holes of the plug pins which extend into the holes of the cover part 1. In this case, the material of the cover part 1 need not meet the same electrotechnical requirements as the material in contact with or supporting the live metal parts. This also serves the purpose of the invention that interchangeable cover parts 1 can be used to create different product variants where the inner part 5 remains the same.
