Description

Electrical socket

Technical field

The utility model relates to a kind of supply socket, and particularly but relate to a kind of electrical socket nonexclusively, it is suitable for being connected to power supply and is suitable for receiving plug, and described plug is connected to the electrical equipment that will be connected to described power supply.

Background technology

The conventional design of plug comprises three pins, and one of them pin is longer and be usually arranged for the object of ground connection than other pin.

When being inserted in socket by plug, grounding pin is arranged to engaged with socket aperture before other two pins engage with other socket aperture completely and enter in described socket aperture usually.

When using above-mentioned plug and socket, a difficult problem running into is plug base pin and the aiming at of socket aperture.This is relevant especially to longer grounding pin; Once longer grounding pin is aimed at hole, other two pins of plug will relatively easily be aimed at the respective aperture in socket, particularly when pin and the hole of rectangular cross-sectional shape.

When socket be positioned to be not easy to see for user or close position, or when by caliginous librarian use, realizing aiming at is difficulty especially.

Described by for auxiliary phase a suggestion of socket polarized plug having been had in the specification of British patent GB 818683.In this patent, describe a kind of socket, it has the V-arrangement recess limited by two faces 13, and described two faces 13 limit the degree of depth of recess and 10 to extend in the direction perpendicular to this face before socket.Inclined plane 13 extends to recessed flat surfaces 12, and grounding pin hole is positioned at the bight place as V-arrangement apex region of this flat surfaces.A shortcoming of this structure is that the flat surfaces of recess itself does not have the effect guiding grounding pin towards ground hole, the substitute is and depends on V-arrangement surface 13.Another shortcoming of structure disclosed in GB 818683 is that it visually has no attraction.

Utility model content

The utility model aims to provide a kind of electrical socket of improvement, and it overcomes or alleviates the shortcoming of hitherto known existing socket.The present invention is by the following technical solutions:

A kind of electrical socket, for receiving the plug of the type comprising at least one pin, described socket comprises the panel with smooth face, described panel is defined at least one hole of receiving described pin, it is characterized in that, described panel forming is limit around the recess area in described hole, and described recess area is limited by following surface, this surface relative to the plane of the panel surface around recess area to be less than the inclined at acute angles of an angle of 90 degrees degree.

Embodiment

Duplex electrical socket 10 comprises two groups of each three two control switchs 13 received the hole 11,12 of pin and locate with normal arrangement.

Socket 10 comprises the panel 14 with substantially flat face 15, and it is provided with the hole of above-mentioned receiving pin and also has for the hole of the rocking arm of call access control switch 13.

Panel provides support to the typical terminal block 21 comprising electric terminals and control switch.Terminal module 21 (briefly showing in Fig. 2 to Fig. 4) is fixed to the rear portion of panel in known manner.Panel is also provided with pair of holes 23, for receiving such as socket being fixed to the device of the screw of supporting construction.

Although be essentially plane, before described panel 14,15 are formed with two recess area 16, and each recess area is around the corresponding hole in two holes 11, and described hole 11 is designed to the grounding pin of receiving three pin plug.15 also comprise the lower tilt region 15a for strengthening visual attraction above.

Each recess area 16 comprises two surf zones 17,18, and they are symmetrical relative to the line C-C in Fig. 1.In the side of hole 11 closest to the hole 12 in three Kong Suocheng arrays, recess area comprises surf zone 19.

Each surf zone 17,18,19 relative to before the general planar of described socket 15 substantially integrally with 5 degree within the scope of 10 degree, be more particularly the angle location of 8 degree.

Until position 22 approximately middle between grounding pin hole 11 and the top edge 20 of socket, recess area has the uniform degree of depth substantially.But cross this intermediate point, recess area has the cumulative degree of depth (viewgraph of cross-section see Fig. 4), depth capacity on top edge 20 place and be about 3/4ths of panel depth.The cumulative degree of depth width cumulative with the recess area of crossing this intermediate point is associated, and recess area has the roughly Y shape profile arrived as viewed in fig. 1 thus.

Correspondingly, recess area has the profile of the cross section got along the line B-B of Fig. 1 shown in Fig. 3 and has profile as shown in Figure 2 when the direction in Fig. 1 arrow A is observed.

As the result of the aforementioned shapes of recess area, the profile of the top edge 20 of panel assists user to determine the position (side to side position) of the edge-to-edge residing for grounding pin hole approx easily.In addition, even if when making grounding pin in position farther apart from top edge 20 compared with grounding pin hole 11 and plate contact at first, the recess area being arranged to extend around grounding pin hole is completely provided also to contribute to guiding the grounding pin of plug to engage with grounding pin hole.

Therefore, as by as can be seen from Figure 5, when not damaging socket visual appearance, advantageously facilitating plug is engaged the easness of locating with socket.
