Description

Female power cord socket for connection to either a

  iron to rewire electrically either on a base of

receiving the iron.

  The present invention relates to a power cord socket intended to be connected to an electric iron, comprising a rear cover forming a heel on which said iron comes to rest when ironing is interrupted, or on a receiving base iron on his

heel.

  The invention relates, more particularly, to such a receptacle comprising in a housing at least two female electrical contacts in which are connected either pins of the iron qi: i protrude transversely to the heel, or pins of the base which protrude from the base , the pins of the iron and the base passing through openings arranged on the

  socket housing opposite the electrical contacts.

  This type of catch is known. So that the socket can be selectively connected to the iron or the base, it must be ensured that it allows to put the iron on his heel when ironing is interrupted, and the fact that the cord is generally directed upwards, it does not reduce

  not the handling of the iron during ironing.

  The object of the invention is to provide a grip that responds to

  these requirements while providing an improvement.

  According to the invention, the openings are divided into two series, namely openings of the iron and openings of the base, respectively arranged on two transverse faces of the housing of the socket, each electrical contact being disposed opposite to both an opening iron and an opening of the base, so as to allow the connection of the plug, either on the iron with the cord directed towards the top of the heel, or on the base with the cord directed horizontally. The device therefore has the advantage of imposing the appropriate orientation of the cord according to the type of

branching done.

  The features and advantages of the invention will emerge

  from the following description, as a

  for example, with reference to the accompanying drawings in which: Figure 1 is a perspective view of a socket according to the invention; Figure 2 is a horizontal sectional view along the line II-II of Figure 1; Figure 3 is a partial vertical sectional view of an iron illustrating the setting in place on the rear cover of said iron; FIG. 4 is a partial view in vertical section of a base

  illustrating the setting up on this base.

  In Figures 1, 3 and 4 is shown a female socket 1 of power cord 2 (shown in dashed lines) for connection to an electric iron and iron 3, having a rear cover 4 forming heel 4 'on which said iron comes to rest when ironing is interrupted, either on a base 5 for receiving the iron on its heel 4 ', said socket 1 having in a housing 6 three female electrical contacts 7,7' in which are connected either pins of the iron 8 which protrude transversely to the heel 4 ', or pins of the base 9 which project from the base 5, the pins of the iron 8 and the base 9 passing through openings 10, 11, 11' arranged on the housing 6 of the socket 1 facing the electrical contacts 7.7 '. According to a particularly advantageous characteristic of the invention, the openings 10, 11, 11 'are distributed in two series, namely openings of the iron 10 and openings of the base 11, 11', respectively arranged on two transverse faces 12, 13 of the housing 6 of the socket 1, each electrical contact 7,7 'being arranged facing both -an opening of the iron 10 and an opening of the base 11,11', so as to allow the connection of the socket 1, either on the iron 3 with the cord 2 directed towards the top of the heel 4 (FIG. 3), or on the base 5 with the cord 2 directed

horizontally (Figure 4).

  Thus, the connection of the socket 1 is made in an appropriate orientation: when the socket 1 is connected. on the iron 3, the cord 2 directed upwards ensures good handling of the iron 3 during ironing and allows the iron 3 to be placed on its heel 4 ', whereas when the plug 1 is connected to the base 5, the cord 2 directed horizontally prevents the hot sole 14 (shown in broken lines in Figure 4) of the iron 3 burns said cord 2 (which could happen if the cord was directed upwards). In addition, this arrangement makes it possible, for example, to fix the base 5, for example on an ironing board, since the socket 1 is connected laterally and not below the ironing board.

base 5.

  As can be seen in FIG. 2, the receptacle 1 has three contacts 7, 7 ', two of which 7 are distributed on either side of a ground contact 7', each contact 7, 7 'being constituted by a blade U-shaped metal whose branches 15 respectively have curved ends 16 convexity turned towards each other, so that the

4 2648961

  pins of the base 9 passing through the openings of the base 11, 11 ', are placed between the branches 15 along the axis of U while the pins of the iron 8 through the openings of the iron 10 are placed between the branches 15 along an axis perpendicular. Contacts 7.7 'are kept apart from each other

  by supports 17 integral with the casing 6.

  Each contact 7, 7 'has at its curved ends 16 and respectively at its edges 18 facing the openings of the iron 10, two diverging tabs 19 directed towards the openings of the iron 10 so as to facilitate

  the introduction of the iron pins 8 between the branches 15.

  Thus, the curved ends 16 of the branches 15 make it possible to guide the pins of the base 9 in the axis of the U, whereas the diverging lugs 19 make it possible to correctly guide the pins of the iron 8 between the curved ends 16 in the axis perpendicular to the U In addition, the elasticity of the branches 15 makes it possible to obtain a good contact with the pins 8, 9. As shown in FIG. 3, the rear cover 4 has in its rear face 4 'a housing 20 opening upwards. and towards the rear and intended to receive the socket 1. The socket 1 and the iron 3 comprise mutual locking means which comprise, on the one hand, on the socket 1 a hole 21 made in the face 12 of the casing 6 comprising the openings of the iron 10, and secondly, on the iron 3 a latch 22 slidably mounted in a guide 22 'in a direction parallel to the bottom 23 of the housing 20 and having a hook 24 which can occupy two positions, a position locking (not repro sented) at which it enters the hole 21 and engages on the inner edge 25 of the hole 21, an unlocking position in which it is brought by a handle 26 arranged outside the housing 20

  and for which it is unhooked from said edge 25.

2648961

  Locking is necessary to maintain good contact between the iron pins 8 and the electrical contacts 7, 7 '

  when the plug 1 is connected to the iron 3.

  The operation of these mutual locking means is carried out as follows. When the plug 1 is connected to the iron 3, the iron pins 8 pass through the openings and come into contact with the electrical contacts 7, 7 '; simultaneously the hook 24 of the latch 22 enters the hole 21 and clings to the inner edge 25; socket 1 is then locked. To unlock the socket 1, is pressed on the handle 26 which pivots about an axis a and thanks to a hinge made in b, the latch slides in its guide 22 'upwards parallel to the bottom 23 of the housing; this translation of the lock is transmitted at the hook 24 which releases the edge 25; it is then sufficient to pull the socket 1 towards the rear; once released, release the controller

  and the lock returns to its original position.

  As shown in Figure 4, the base 5 has a housing 27 opening laterally for receiving the socket 1. The pins of the base 9 are electrically connected to connecting means 28 (shown in broken lines) between the iron 3 and the base 5. The upper wall 29 of the base 5 is V-shaped, so when the iron 3 comes to rest on the base 5, the sole 14 bears on one of the arms of the V and the heel 4 'on the other 31. The pins of the iron 8 come through holes 32

  and come into contact with the connecting means 28.

  As can be seen in FIG. 1, the pins of the iron 8 and the corresponding iron connection openings 10 are aligned while the base pin 9 and the opening of the base 11 'corresponding to the earth contact 7' are offset by compared to the other two 9,11. Thus, it is not possible to connect the plug 1 to the iron 3 with the cord 2

directed horizontally.

6 2648961

  Note also that, in the connection position, the openings 10 or 11,11 'in which do not penetrate the pins 8 or 9, are hidden: the horizontal face 33 of the housing 20 of the rear cover 4 of the iron 3 masks the openings of the base 11, 11 'when the plug i is connected to the iron 3 and the lower horizontal face 34 of the lateral housing 27 of the base 5 masks the openings of the iron 10 when the plug 1 is connected to the base 5. Thus the security is

  increased, because no object can be introduced.
