Abstract

A sleeve for an electric lead (9) for fitting in an electrical appliance has a kink-prevention part (1) for entry of an electric lead into the appliance and an electric lead guiding part (4) joined to the kink-prevention part (1) for extending through the interior of the appliance through partition walls (6, 7) towards a terminal plate (8). The sleeve enables an electric lead to be guided towards the terminal plate as the lead is pushed through the sleeve and thereby allows easy replacement of such a lead, even if several partition walls have to be passed through within the housing before the terminal plate is reached. <IMAGE>

Description

SPECIFICATION Sleeve for an electric lead This invention relates to a sleeve for an electric lead.
With electrical appliances having electric connnecting cables or leads which are arranged fast on the appliances, there are regulations and orders which specify that the user has to be able to replace such connecting cables or leads with a normal tool. Where the housing structures of the appliances are complicated, this leads to the constructions having to be so designed that parts of the housing structures are able to be removed in a simple manner in order to replace the leads from the terminals within the appliances. This necessarily involves a heavy expense for construction and development of the appliances concerned and it is aiways still necessary for several parts of the appliance housings to be removed in order to change the leads (after failure, for example).
According to the present invention, there is provided a sleeve for an electric lead for fitting in an electrical appliance, said sleeve having a kinkprevention part for entry of an electric lead into the appliance and an electric lead guiding part joined to said kink-prevention part for extending through the interior of the appliance towards a terminal connection location, the sleeve enabling an electric lead to be guided towards the terminal connection location as the lead is pushed through the sleeve.
For a better understanding of the invention and to show how the same may be carried into effect, reference will now be made, by way of example, to the accompanying drawing in which: Figure 1 is a diagrammatic side view of a sleeve according to the invention for an electric lead for fitting in an electrical appliance, and Figure 2 is a diagrammatic view, partly in section, through part of an electrical appliance housing and showing the sleeve of Figure 1 fitted therein and with an electric lead passing therethrough.
Figure 1 shows a sleeve for an electric lead for fitting in an electrical appliance, the sleeve being shown in its generally usual form. The sleeve has at one end a kink-prevention part 1 for entry of an electric lead into the appliance and an electric lead guiding part 4 joined to the kink-prevention part 1. An encircling groove 2 is between the two parts, by which means the sleeve is secured to the appliance and is held in the appliance housing.
As shown in Figure 2, the sleeve is fixed on a housing wall 5 by means of the groove 3, the kink-prevention part 1 lying outside the housing and the lead guiding part 4 lying within the housing.
As shown, the housing is provided with intermediate walls or partitions 6, 7 and if it is now visualised that this housing is provided with additional intermediate walls or partitions 6, 7, and a terminal connection location in the form of a terminal plate 8 for an electric lead 9 is situated deep in the housing, then it would be necessary for the user, who wishes to remove and replace the electric lead 9, without having the advantage of the present sleeve, to carry out a relatively complicated dismantling and assembly operation or, alternatively, the electric lead 9 has to be carefully threaded through the several partitions 6 and 7.
With the present invention, however, the guiding part 4 is formed directly on the kinkprevention part 1 of the sleeve, the part 4 constituting a duct which extends towards and as far as the terminal plate 8 when the appliance is manufactured. It is therefore possible for the lead 9 to be simply pushed at the entry to the sleeve into the kink-prevention part 1 and it is automatically guided through the partitions 6, 7 as far as the terminal plate 8. It is therefore possible for the electric lead 9 to be easily replaced, even where the housing is of a complicated design.
In the example shown, the two parts of the sleeve are homogeneous as regards materiai.
Claims
1. A sleeve for an electric lead for fitting in an electrical appliance, said sleeve having a kinkprevention part for entry of an electric lead into the appliance and an electric lead guiding part joined to said kink-prevention part for extending through the interior of the appliance towards a terminal connection location, the sleeve enabling an electric lead to be guided towards the terminal connection location as the lead is pushed through the sleeve.
2. A sleeve as claimed in Claim 1, wherein said kink-prevention part and said electric lead guiding part are homogeneous as regards material.
3. A sleeve as claimed in Claim 1 or 2 and being provided with an encircling groove between the two parts to enable the sleeve to be held in a wall of an appliance housing.
4. A sleeve for an electric lead for fitting in an electrical appliance, substantially as hereinbefore described with reference to the accompanying drawing.
5. An electrical appliance having a sleeve as claimed in any one of the preceding claims.

Figure 1 shows a sleeve for an electric lead for fitting in an electrical appliance, the sleeve being shown in its generally usual form. The sleeve has at one end a kink-prevention part 1 for entry of an electric lead into the appliance and an electric lead guiding part 4 joined to the kink-prevention part 1. An encircling groove 2 is between the two parts, by which means the sleeve is secured to the appliance and is held in the appliance housing. As shown in Figure 2, the sleeve is fixed on a housing wall 5 by means of the groove 3, the kink-prevention part 1 lying outside the housing and the lead guiding part 4 lying within the housing. As shown, the housing is provided with intermediate walls or partitions 6, 7 and if it is now visualised that this housing is provided with additional intermediate walls or partitions 6, 7, and a terminal connection location in the form of a terminal plate 8 for an electric lead 9 is situated deep in the housing, then it would be necessary for the user, who wishes to remove and replace the electric lead 9, without having the advantage of the present sleeve, to carry out a relatively complicated dismantling and assembly operation or, alternatively, the electric lead 9 has to be carefully threaded through the several partitions 6 and 7. With the present invention, however, the guiding part 4 is formed directly on the kinkprevention part 1 of the sleeve, the part 4 constituting a duct which extends towards and as far as the terminal plate 8 when the appliance is manufactured. It is therefore possible for the lead 9 to be simply pushed at the entry to the sleeve into the kink-prevention part 1 and it is automatically guided through the partitions 6, 7 as far as the terminal plate 8. It is therefore possible for the electric lead 9 to be easily replaced, even where the housing is of a complicated design. In the example shown, the two parts of the sleeve are homogeneous as regards materiai. Claims
1. A sleeve for an electric lead for fitting in an electrical appliance, said sleeve having a kinkprevention part for entry of an electric lead into the appliance and an electric lead guiding part joined to said kink-prevention part for extending through the interior of the appliance towards a terminal connection location, the sleeve enabling an electric lead to be guided towards the terminal connection location as the lead is pushed through the sleeve.
2. A sleeve as claimed in Claim 1, wherein said kink-prevention part and said electric lead guiding part are homogeneous as regards material.
3. A sleeve as claimed in Claim 1 or 2 and being provided with an encircling groove between the two parts to enable the sleeve to be held in a wall of an appliance housing.
4. A sleeve for an electric lead for fitting in an electrical appliance, substantially as hereinbefore described with reference to the accompanying drawing.
5. An electrical appliance having a sleeve as claimed in any one of the preceding claims.
