Abstract

The invention relates to an elastic socket having a large load capacity for electrical items such as lamps, light bulbs, etc. Said socket comprises a base or shell (1) formed by a top hollow cylindrical section (2) that is closed on the top end and a thin lower hollow cylindrical section (3) having a larger diameter and consisting of a top portion (4) that is slanted outward and attached by its lower periphery to a cylindrical portion (5) having a peripheral flange (6) on its lower edge. The top surface of the top section (2) has three notches (7, 8 and 9) with three circular perforations (10a, 10b and 10c). The inner part of the base or shell (1) has a thin semi-cylindrical metal section (11) with a portion (P) folded at a 90° angle, a circular perforation (12), a pair of legs (13) to hold a spring (14), holding means (15) to hold together the semi-cylindrical section (11) and the cylindrical section (2) by the perforation (10c) thereof with a cable (c1+), in addition to a semi-elliptical metal plate (16) with a circular perforation (17) and a projection (18), and holding means (19) to hold together the semi-elliptical plate (16) and the top section (2) by its perforation (10a) with a cable (C2-). In the inner part of the base or shell (1), a plurality of semi-radial bulges (20) is located in approximately two thirds of the perimeter thereof, said bulges acting as a stop against the base of a lamp, light bulb, etc. due to the considerable increase of friction that it generated when combined with the elastic principle of the socket. This makes it possible for said item weighing approximately 3 kg. to be introduced and removed. The invention also relates to an elastic socket having a high load capacity consisting of a base or shell (21) formed by a top hollow staggered cylindrical section (22) and closed on its top end, a lower thin hollow cylindrical section (23) and a hollow threaded adapter (24) that is closed on its top end which is held by pressure and with an adhesive on the top staggered section (22) to attach a conventional socket.

Description

ELASTIC SOCKET FOR ELECTRICAL ITEMS

D E S C R I P C I Ó N

The invention consists of a large capacity socket for electrical items, such as spotlights, light bulbs, etc. Said socket is formed of a socket with receiving holes of power cables, in its upper part; said bushing housing, in its internal part, an angular piece with a resilient means and an elongated piece joined by means of fastening to said perforations. In the inner peripheral part of said socket a plurality of semi-radial protuberances that act as a brake center the focus base, bulb, etc. is located. Also, said bushing can be of stepped configuration and contain an adapter for conventional socket, which is attached by its lower internal periphery, under pressure or with adhesive, to the upper part of said bushing.

FIELD OF THE INVENTION The present invention relates to connection devices for spotlights, lamps, etc. and, more particularly, with elastic sockets of great load capacity, for spotlights, electric bulbs, and the like.

BACKGROUND OF THE INVENTION At present there is a multiplicity of devices that function as sockets, which allow foci to be introduced, screwing into them, the majority of these sockets being brass. Likewise, these sockets have the disadvantage that, in most cases, it is difficult to attach and decouple these bulbs threadedly, since they are stuck or screwed and, when removed, they can break or suffer fractures on their surface, causing accidents .

There are also planned sockets of elasticity in its internal diameter so that it is sufficient to push a bulb, bulb, etc. out of said socket, so that it is later removed without causing any of its components to break down, such is the case of elastic sockets. eos "of US Patent No. 4,915,667 and Mexican Patent No. 160,162, owned by the inventor of the present application, which support a low load capacity. OBJECTIVES OF THE PRESENT INVENTION A first objective of the present invention is to provide an elastic socket for electrical items, such as spotlights, light bulbs, and the like, that have a large load capacity.

A second objective of the present invention is to provide a socket that is durable, easy to install and maneuver.

A third objective of the invention is to provide an elastic socket that can be attached to any conventional cord socket. Taking into consideration each and every one of the disadvantages of the prior art and the aforementioned objectives and others more not mentioned, the inventor of the present invention carried out a multitude of studies, tests and trials that led him to design novel elastic sockets that they overcome all the disadvantages of the prior art and provide a multiplicity of advantages, which is of paramount importance in the part of engineering where this invention is understood.

An elastic socket of great load capacity, of the present invention, for electrical articles, such as spotlights, bulbs etc., consists of a stylized cylindrical bushing, with cable receiving holes and fastening means, in its upper section, and a angular plate with a spring and a small semi-elliptical plate, in its internal part, both attached to said bushing by rivets. Also, the bushing includes a plurality of semi-radial protuberances in most of its internal periphery. Said elastic socket with its fastening means and its protuberances, which act as a brake against the base of the bulb, electric bulb, etc., due to the considerable increase of friction that this generates in combination with the elastic principle of the socket, is capable of withstand a load of approximately 3 kg. which is currently a requirement, because there are screens on the market that are completely attached to the bulb or electric bulb, and whose weight is around 3kg.

The socket of the present invention is very durable, easy to transport and install, and is capable of maintaining good contact with bulbs, electric bulbs and the like, even in shaking or sudden movements, and can be made of light and resistant materials such as hard plastic , bakelite, ceramics, porcelain, etc. The sockets of the present invention can have different external configurations, that is, their socket can be stylized cylindrical or stepped cylindrical. The staggered socket socket includes a conventional socket adapter, which is fixed under pressure or with adhesive to the top of the staggered socket socket.
