Description

"IMPROVEMENT IN SOCKET AND FAST COUPLING TERMINAL ASSEMBLY FOR FLUORESCENT OR INCANDESCENT LAMPS ".

This description refers to an improvement in a socket and fast coupling terminal for fluorescent or incandescent lamps and, more particularly, to a pieces assembly that compose a terminal adaptable to each one of the end poles of the fluorescent lamp and to a receptacle magnetic socket to be mounted in the luminaire in which the lamp will be installed.

As it is known in the state of the art, currently the fluorescent lamps are provided with an electric connection terminal that has coupling means for the terminals of a fluorescent type lamp. These conventional lamps are adapted by pressure and rotation fitting relative to the said sockets which are provided in a parallel fashion and distanced from each other in a measure equivalent to the length of the lamp, or in other types of sockets the lamp pins where flexible stems have orifices with internal electric contacts where the lamp terminals are fitted, being that irrespective of the manner how the fitting is done, this is always made in a mechanical manner that requires that the lamp or the socket is dislocated or rotated, what obliges the user to hold the lamp and eventually displace the socket.

Thus, the closing of the electric circuit of power supplying of the lamp is defined by the contact of the parallel pins provided in the two ends of the lamp with the respective sockets of the couple of sockets which are electrically connected to power supply network.

This contact is made under radial pressure of the pins in the sockets rails, which pressure is effected by the rotation of the lamp around its axis, making the contact pins to slide along the socket rail that is extended in an irregular arch, causing in this way the relative radial pressing of the lamp in the sockets.

With this conventional construction conception the electric coupling of the lamp with the power generating socket is made by the physical contact of the relevant terminal pins of the lamp with the metallic blades existent in the interior of the arched rails of the sockets, whereas the mechanical and/or physical coupling between the lamp and the sockets is guaranteed by the fitting of the lamp pins in the sockets rails and posterior rotation of the lamp around its axis, making the pins to slide and lock by radial pressure in the sockets rails.

In spite of widely utilized, this type of connection between the lamp and the sockets requires that the rotation be effected until its end of course in order to establish the physical contact between the terminals and the respective locking by pressure of the lamp in the sockets. This makes the user to force the lamp against the socket, causing frequent displacements between the metallic terminal and the glass bulb and/or causes a mechanical deformation of the lamp pins.

Another inconvenient of this type of lamp adaptation is the very form of connection demanded, namely, the rotation of the lamp between two sockets, task that is not always easy, for instance, for a woman during the changing of a burnt lamp.

Still another inconvenient verified in this type of connection between fluorescent lamp and sockets, refers to the fact that the electric connection only occurs when there is a tight fitting between the pins and the surfaces of the sockets rail. If there is even a minimum slack the electric circuit is not closed and the lamp is not energized, or when there is loss of flexibility of the socket interrupting the electric contact.

Considering that, in many of the cases, the user by fear of breaking the lamp in its connection to the socket or fearing to cause a deformation of the contact pins, does not make a rotation of locking and electric connection until its end of course, increasing the possibilities of the inexistence of electric contact, and even if an initial electric contact occurs, any environmental vibration may cause a slight rotation of the lamp relative to the socket, sufficient for the loss of electric contact.

It is one of the objectives of this invention to provide an improvement in the socket and fast coupling terminal assembly for fluorescent lamps that makes possible the adequate electric coupling between the lamp terminals and the socket without generating any inadequate effort in the lamp that may cause its breakage.

Another objective of this invention is to provide an improvement in the socket and fast coupling terminal assembly that does not requires the rotation of the lamp relative to the socket, eliminating all the inconveniences of this type of installation.

Another objective of this invention is to provide an improvement in the socket and fast coupling terminal assembly with physical support for fluorescent lamps that allows an easy and fast coupling by axial fitting between the pieces, what stimulates, for instance, a woman to change a burnt lamp without fear of causing an accident of the above mentioned type.

Another objective of this invention is to provide an improvement in the socket and fast coupling terminal assembly for fluorescent lamps that guarantees an effective permanent electric connection besides a magnetic physical connection between the terminal and surfaces, both of the lamp and of the sockets, not allowing any type of interference between the electric contacts and, consequently, not allowing the opening of the electric circuit that energizes the lamp.

These and other objectives and advantages of this invention are attained with an improvement in socket and fast coupling terminal assembly for fluorescent lamps that comprises in a magnetic socket of axial contact externally defined by a parallelepiped-like body made of electric insulating material, in the interior of which is coaxially mounted a metallic piece conductor of electricity that is maintained in contact with a magnet, defining a surface of physical coupling by magnetic effect, due to the interaction of the magnet with the conductor metallic piece, disposed near to the magnet capable of effecting the coupling with metallic terminals anticipated in the lamps. As it is known in the state of the arl, currently the incandescent lamps are provided with an electric connection terminal defined by an externally threaded cylindrical neck for physical connection to the socket and end terminal of tapered format provided with electric contact defined by an end projection coaxially disposed relative to the geometrical axis of said lamp. These conventional lamps are adapted by threading in corresponding sockets defined by a cup of electric insulating material such as porcelain or bakelite, having internally mounted a corrugated metallic capsule determining in its contouring ring-shape wall a thread pitch compatible with that defined by the connection neck of the lamp. In the bottom wall of this cup there is provided a laminar tab electrically connected by contact under pressure with said end terminal and projection provided in the connection neck of the lamp.

Thus, the closing of the electric circuit of power supplying of the lamp is defined by the contact between the contouring wall of the lamp neck and the ring-shaped wall of the metallic capsule, electrically connected to one of the poles of the network; and by the contact under pressure and axial of the end projection of the lamp neck with the laminar tab, electrically connected to the other pole of the network, provided in the bottom wall of the insulating cup that defines the socket.

With this conventional construction conception the electric coupling of the lamp with the power generating socket is made by the physical contact of the relevant walls of the lamp end with the capsule, whereas the mechanical and/or physical coupling between the lamp and the socket is guaranteed by the threading between the lamp end and the capsule encased in the socket.

In spite of widely utilized this type of lamp and socket connection, the manner utilized for the fixing by threading of the lamp requires that the threading be effected until its end of course in order to occur the physical contact between the axial terminals of electric closing of the circuit between lamp and socket. This makes the user to force the lamp against the socket, causing frequently the unglueing between the metallic terminal and the glass bulb and/or the locking between the thread pitch of the terminal with the capsule inside the socket, causing in this case the breakage of the lamp for the removal of the terminal with the help of pliers.

Another inconvenience of this type of adaptation of lamp is the very form of connection required, namely, the threading between two pieces, where one of them is fragile, what does not stimulate, for example, a woman to change a burnt lamp, by fear of causing some accident of the above mentioned type.

Additionally, another inconvenience verified in this type of connection between incandescent lamp and socket, refers to the fact that the electric connection only occurs when there is the snug fitting and of top between the terminals and the surfaces, both of the lamp and of the socket. In case there is even a minimum of gap the electric circuit is not closed and the lamp is not energized.

Considering that, in many of the cases, the user by fear of breaking the lamp close to the socket or fearing to cause a locking between this latter and the socket, does not make the threading until its end of course, the possibilities of the inexistence of electric contact are very great as, even if an initial electric contact occurs, any environmental vibration may cause a slight unthreading of the lamp relative to the socket, sufficient for the loss of the electric contact. It is one of the objectives of this invention to provide an improvement in the socket and fast coupling terminal assembly for incandescent lamps that makes possible the adequate electric coupling between the lamp terminals and the socket without generating any inadequate effort on the lamp that may cause its breakage.

Another objective of this invention is to provide an improvement in the socket and fast coupling terminal assembly for incandescent lamps that does not require the threading between lamp and socket, eliminating all the inconveniences of this type of installation. Another objective of this invention is to provide an improvement in the socket and fast coupling terminal assembly for incandescent lamps that allows an easy and fast coupling by axial fitting between the pieces, what stimulates, for instance, a woman to change a burnt lamp without fear of causing an accident of the above mentioned type. Another objective of this invention is to provide an improvement in the socket and fast coupling terminal assembly for incandescent lamps that guarantees an effective, permanent, and of top electric connection between the terminal and surfaces, both of the lamp and of the socket, not allowing any type of interference between the electric contacts and, consequently, not allowing the opening of the electric circuit that energizes the lamp.

These and other objectives and advantages of this invention are attained with an improvement in socket and coupling terminal assembly for incandescent lamps that comprises in a socket defined by a cup of electric insulating material, such as porcelain or bakelite, in the interior of which is coaxially mounted upon it bottom wall, a ring piece composed by a magnetized portion capable of defining a surface of physical coupling and a coaxial metallic portion with electric conductivity capable of accomplishing the top coupling with the contouring walls of the connection neck of the lamp; being that centrally and in a lowered plan of this ring piece, the said electric insulating cup is provided of a laminar tab electrically connected by contact under pressure to the end and projected terminal provided in the connection neck of the lamp; being that the cylindrical neck of physical and electric connection of the lamp to the socket, defined by smooth and metallic external and bottom walls magnetically retained to the socket through the magnetized portion of the ring piece and electrically connected to one of the energizing poles of the network; whereas the smooth bottom wall of the neck of the lamp allows the projection, axial and electrically insulated of the remaining part of the neck, of an electric contact terminal defined by an end projection coaxially disposed relative to the geometric axle of said lamp, actuating under pressure on the laminar tab, electrically connected to the other pole of the network, connected to the terminals of the body or insulating cup that defines the socket.

As can be seen in the figures 13 to 16, this magnetic socket 10a embodies a rigid fence and in electric insulation 1e that is projected beyond the plane that contains the pieces2a and parallel to the lateral rims 1 b, which prevents that a same pole 31 of a lamp 30 simultaneously leans in the two contact terminals 2a.

As can be seen in the figure 13, in the same manner the external part 1 of the body of the magnetic socket 10a is fixed in the luminaire 40 in which the lamp 30 will be installed. As illustrated in the figure 7, the terminals 20b of physical and electric connection of the contact pins 31 of the lamp 30 with the sockets herein defined by the magnetic sockets 10 or 10a, are defined, each one by a round pin with radial tightening screws 21 b configuring a tubular sleeve, through which is trespassed the corresponding end pin 31 of contact of the lamp 30.

Thus the terminals 20c are axially adapted by pressure to the end pins 31 of the lamp 30. As can be seen in the figure 9, the terminals 20d of physical and electric connection of the contact pins 31 of the lamp 30 with the sockets herein defined by the magnetic sockets 10 or 10a, are defined by a couple of round pins 21 d embodied to a flexible hubcap 22d of diameter compatible with the diameter of the end of the lamp 30 so as to allow the snug and simultaneous fitting of the hubcap 22d around the end of the lamp 30 and of the pins 31 of this latter in the round pins 21 d.

As can be seen in the figure 10, the terminals 20e of physical and electric connection of the contact pins 31 of the lamp 30 with the sockets herein defined by the magnetic sockets 10 or 10a, are defined by a couple of round pins 21 e and incorporated to a rigid and of electric insulating 22e material hubcap of diameter compatible with the diameter of the end of the lamp 30 so as to allow the snug and simultaneous fitting of the hubcap 22e around the end of the lamp 30 and of the pins 31 of this latter in the round pins 21 e.

According to figures 17, 18, 19 and 20, the improvement in socket and coupling terminal assembly for incandescent lamps, object of this invention, is comprised by a socket 110 of the type defined by a cup made of electric insulating material, such as porcelain or bakelite or other equivalent material, said socket 110 presenting circular bottom wall 11 , tubular contouring wall 12 of compatible height to involve the neck 121 of electric and mechanical connection of the lamp 120 to be described farther on.

This socket 1 10 embodies internally in a fixed and coaxial manner upon its bottom wall 11 , a ring piece 111 composed by a radially external magnetized portion 111 a and by a coplanar and radially internal metallic portion with electric conductibility 111 b, as illustrated in the figures; being the first portion 1 11a capable of defining a coupling and physical retention surface of the lamp 120, through its connection neck 130, in the socket 110, whereas the second portion 111 b is capable of effecting the top electric coupling with the contouring walls 131 of the connection neck 130 of the lamp 120, thus materializing the closing of one of the poles of the electric circuit connected to the electric network that energizes the lamp 120.

The socket 110 embodies centrally and in a lowered plane of this ring piece 111 , a laminar tab 112, electrically connected to the other pole of the electric network, being said tab 112 submitted to a contact under pressure with the end and projected terminal 122 provided in the connection neck 121 , 130 of the lamp 120, as illustrated in the 19 and 20 figures.

As can be seen in the figures 17 and 18; in a first version, the improvement in the socket and coupling terminal assembly for conventional type incandescent lamps is effected with the help of an adaptor 130 of the removable type that serves as interface between the conventional lamp 120 and the improved socket 110.

This adaptor 130, also called removable neck, is constituted by a tubular piece with smooth and metallic external 131 and bottom 132 walls, being the internal face of this adaptor 130 provided of a thread pitch 133, so as to allow its threading in the externally threaded contact neck 121 embodied in the conventional lamp 120. With the placing of this removable adaptor 130 in the externally threaded neck 121 of a conventional lamp 120 one attains the magnetic retention of this latter in the socket 110, through the magnetized portion 11 1a of the ring piece 11 that magnetically retains the adaptor 130 and, consequently, the lamp 120; whereas the projected terminal 122 of this lamp 120 trespasses a circular orifice 134 of the adaptor 130 to be electrically connected under pressure to the laminar tab 112 fixed in the socket 110.

In another version, illustrated in the figures 18 and 20, the improvement in socket and coupling terminal assembly for incandescent lamps consists in providing further an improved lamp 120a, where the very electrical and mechanical contact neck is defined by a tubular piece 130a with smooth and metallic external (131) and bottom (132) walls, such as the removable adaptor 130, only that said piece 130a is directly incorporated in the lamp bulb 120a. In this version the projection 122 of electric contact with the tab 112 of the socket 110, is embodied in the very bottom wall 132 of the tubular piece 130a.
