Abstract
Description
- The present invention refers to a lampholder comprising a thermal switch adapted to protect the appliance in which it is installed from excessive temperature increases.
- A lampholder produced according to the invention has been designed particularly for electrical appliances, and in particular for refrigerators where a prolonged lighting of the lamp inside the refrigerator, due to a malfunction of the switch normally controlled by the refrigerator door or to a prolonged opening of said door causes (or could cause) an unwanted increase in the temperature inside the refrigerator.
- Recent changes to the standards require a test to be carried out with the light on and the refrigerator door closed: during said test the temperature inside the refrigerator exceeds the values that can be measured during the normal operation and could exceed the values permitted by the plastic materials employed inside said refrigerator, which risk being damaged.
- For this reason, it has become necessary to insert in the supply circuit of the lamp a thermal switch which cuts off the power supply to the lamp when the temperature inside the refrigerator exceeds a pre-set value and which restores the power supply to the lamp as soon as said temperature returns to normal.
- There exist on the market different types of thermal switches of various sizes and action types, which are normally connected to the lampholder contacts by soldering, by crimping, by abutment on terminals or on rapid connectors, and so on.
- The aforementioned connection methods make it practically impossible to reduce the manufacturing costs of the lampholder by automating the assembly thereof and, in particular, by automating the assembly of the thermal switch inside the lampholder.
- The large number of types of lampholder used by each electrical appliance manufacturer (in particular by the refrigerator manufacturers), the high cost and the long times necessary to modify them in order to adapt them to meet with the new standards and the difficulties in managing two or more similar versions have given rise to the need for a lampholder which, besides incorporating the thermal switch, maintains the overall dimensions more or less unchanged if compared with the models already in use.
- Object of the present invention is to produce a lampholder for an electrical appliance, in particular for a refrigerator, that includes a thermal switch (or other functionally equivalent thermal protection means) incorporated in the lampholder and which is free from the limits and the drawbacks previously mentioned; this object is achieved by means of a lampholder which has the characterising features indicated in the
independent claim 1. - Further characteristics of the invention will be apparent from the dependent claims.
- The invention will now be described with reference to a purely exemplifying and therefore non-limiting embodiment thereof, illustrated in the appended figures, wherein:
-
Figure 1 shows diagrammatically a side view of a lampholder; -
Figure 2 shows diagrammatically a front view of a lampholder made according to the invention, sectioned along the plane A-A ofFigure 1 ; -
Figure 3 shows diagrammatically a perspective view of the lampholder sectioned as inFigure 2 ; -
Figure 4 shows diagrammatically a perspective view of the lampholder sectioned as inFigure 2 and without the thermal switch and the metal contact members; -
Figure 5 shows diagrammatically a perspective view of a thermal switch; -
Figure 6 shows diagrammatically a front view of the lampholder, sectioned as inFigure 2 , during the insertion of the thermal switch and of the side contact member; -
Figure 7 shows diagrammatically a perspective view of the lampholder, sectioned as inFigure 2 , with the thermal switch in place; -
Figure 8 shows diagrammatically a perspective view of the lampholder, sectioned as inFigure 2 , with the thermal switch and the side contact member in place. - In the appended figures, corresponding elements will be identified by the same reference numerals.
- The present invention refers to a lampholder consisting of a casing, preferably made in a single piece, which comprises at least an inner cavity adapted to accommodate a lamp socket, electrical contacts on which the terminals of the electrical supply cables abut and thermal protection means (preferably a thermal switch) inserted in the connection between one of said electrical contacts and one of the terminals of the lamp socket.
- The thermal switch is preferably mounted removably in a seat made in the side wall of the inner cavity of the lampholder and has on its surface facing said inner cavity a first push-on contact against which the aforementioned electrical contact rests and a second push-on contact connected to a terminal of the lamp socket, preferably by means of a side contact member.
-
Figure 1 shows diagrammatically a side view of alampholder 1 made according to the invention, consisting of a casing, preferably made in a single piece, inside which are situated, as will be described with reference to the subsequent figures, the thermal switch and the metal contact members. -
Figure 2 shows diagrammatically a front view of thelampholder 1, sectioned along the plane A-A ofFigure 1 , which consists of a casing which comprises at least aninner cavity 2 bearing a thread to receive a lamp socket (omitted in the appended figures to simplify the graphic representation), the electrical contacts (3, 4) on which the terminals of the electrical supply cables of the lamp (omitted in the appended figures to simplify the graphic representation) abut and athermal switch 5 inserted in the connection between one of the electrical contacts (3, 4) and one of the terminals of the lamp socket. - The
inner cavity 2 adapted to receive the lamp socket, the circuit which makes up thethermal switch 5 and theelectrical contacts - The
thermal switch 5 is mounted, preferably removably, in aseat 6, made in the side wall of theinner cavity 2 and not visible inFigure 2 because it is occupied by thethermal switch 5. - This removable assembly allows the
thermal switch 5 to be replaced (for example because it is broken or to meet specific requirements) without having to replace the entire lampholder. - As can be seen better in the perspective view of
Figure 5 , thethermal switch 5 has on its surface facing theinner cavity 2 of the lampholder 1 a first push-oncontact 7, against which rests theelectrical contact 3 on which one of the supply conductors of the lamp abuts, and a second push-oncontact 8 against which rests aside contact member 9, seen better inFigures 3 and8 , which protrudes into theinner cavity 2 of thelampholder 1 to connect thethermal switch 5 to a terminal of the lamp socket. - In the embodiment illustrated in
Figures 2, 3 and8 , theside contact member 9 is adapted to connect the second surface push-oncontact 8 of thethermal switch 5 with the threaded side area of the lamp socket but, without departing from the scope of the invention, theside contact member 9 can connect the second surface push-oncontact 8 of thethermal switch 5 with the flat area situated at the end of the lamp socket. - Again without departing from the scope of the invention, the
side contact member 9 can be omitted and the second surface push-oncontact 8 protrudes into theinner cavity 2 of thelampholder 1 to connect thethermal switch 5 to the threaded side area of the lamp socket or to the flat area situated at the end of the lamp socket. - Again without departing from the scope of the invention, the
thermal switch 5 can be replaced by another functionally equivalent thermal protection means, not described because it is per se known, adapted to be mounted in theseat 6 formed in the side wall of theinner cavity 2 of thelampholder 1 and having the surface push-oncontacts -
Figure 3 shows diagrammatically a perspective view of thelampholder 1 sectioned as inFigure 2 ; visible inFigure 3 is the casing inside which are housed theinner cavity 2, theelectrical contacts thermal switch 5, the surface push-oncontact 7 of thethermal switch 5 and theside contact member 9. -
Figure 4 shows diagrammatically a perspective view of thelampholder 1 sectioned as inFigure 2 and without thethermal switch 5 and the metal contact members (3, 4, 9); visible inFigure 4 is the casing inside which are housed theinner cavity 2, the seats designed to accommodate thecontacts seat 6, formed in the side wall of theinner cavity 2, designed to accommodate thethermal switch 5. -
Figure 5 shows diagrammatically a perspective view of athermal switch 5; attention is drawn inFigure 5 to the push-oncontacts thermal switch 5. -
Figure 6 shows diagrammatically a front view of alampholder 1, sectioned as inFigure 2 , during the insertion of thethermal switch 5 into theseat 6 and of theside contact member 9 into theinner cavity 2. - In
Figure 6 thecontact 3 is also visible, whereas thecontact 4 has been omitted. -
Figure 7 shows diagrammatically a perspective view of thelampholder 1 sectioned as inFigure 2 ; visible inFigure 7 are thethermal switch 5 positioned in theseat 6 and the surface push-oncontacts thermal switch 5, whilst thecontacts side contact member 9 have been omitted. -
Figure 8 shows diagrammatically a perspective view of thelampholder 1 sectioned as inFigure 2 ; visible inFigure 8 are thethermal switch 5 placed in theseat 6, theside contact member 9 which rests against the surface push-oncontact 8 of the thermal switch 5 (not visible in the figure because it is covered by the side contact member 9) and the surface push-oncontact 7 of thethermal switch 5. - A
lampholder 1 produced according to the invention holds numerous advantages over the lampholders of the prior art, amongst which the following are cited by way of non-limiting example: - the push-on contacts (7, 8) present on the surface of the
thermal switch 5 allow it to be easily inserted into the supply circuit of the lamp and considerably simplify the assembly of thelampholder 1, which can be carried out with an automatic process since it is sufficient to insert thethermal switch 5 into theseat 6 of thelampholder 1, without particular manual operations being required; - the
lampholder 1 has more or less the same outer dimensions as those of the lampholders currently in use, which it can replace without requiring mechanical and/or electrical modifications to the appliance on which it is installed; - the
thermal switch 5 integrated into thelampholder 1 avoids having to run connection cables between thelampholder 1 and the thermal switch, as would be necessary if the thermal switch were positioned in another area of the refrigerator. - Without departing from the scope of the invention, a person skilled in the art can make to the thermal switch previously described all those changes and improvements suggested by normal experience and/or by the natural evolution of the art.
