Definitions
- Socket for electric lamp with safety shutter Socket for electric lamp with safety shutter.
- the present invention relates to the field of sealed electrical connections of insulated wires passing through a cell. It particularly concerns the field of sealed sockets, intended for automotive or aeronautical equipment, as well as sealed connectors.
- US Pat. No. 5,749,743 also discloses a socket comprising a tubular base for receiving a bulb.
- the base has cells to receive electrical contacts.
- the locking means comprise primary locking means for locking the contact pieces in the lamp holder only when they are fully inserted into the latter, and secondary locking means comprising a latch designed to be able to be brought, after insertion and primary locking of the contact pieces in the lamp holder, of an inactive position in which it prohibits the mounting of the lamp to an active secondary locking position to which it confirms the primary locking of the contact parts and allows the mounting of the lamp.
- Sockets that provide a bad connection detection flap are complex and include at least one flap hinge hinge preventing the use of plastics loaded with fibers. Indeed, the loaded plastics are certainly more resistant but become brittle at the parts subjected to repeated deformations such as hinges.
- the solution of separately manufacturing the sleeve and the flap is also unsatisfactory because it significantly increases the cost of manufacturing the various components of the socket and the assembly of these components (flap and base of the socket, or pivots ).
- the present invention aims to overcome this disadvantage by proposing a sealed socket with a flap foldable only when the connection means are properly engaged.
- the invention relates, in its most general sense, to a socket for an electric lamp comprising at least one cell for receiving connection elements and a cavity for receiving a bulb, characterized in that it comprises a movable flap between a open position allowing the engagement of the connection elements and a locked position accessible only when said connection elements are in place, the socket and the flap being made of a loaded material.
- the filler is preferably fiberglass, with a percentage greater than or equal to 5% by weight, improving the electrical and mechanical resistance of the sleeve but making the plastic material brittle.
- the articulation between the flap and the sleeve is not a hinge, but a joint without contact.
- the percentage of glass fibers is greater than 10% by weight of plastics material.
- the socket is distinguished from the prior art by a hinged or sliding flap, hinged, molded at one time with a plastic material filled with glass fibers, and providing functions for checking the good or bad insertion of the various contacts inserted in the socket.
- This technique opens the way to two-material injection (two colors or two different materials), without complication of the tooling.
- said flap is molded together with the body of the sleeve, in premolded configuration.
- FIG. 1 shows a perspective view of a socket according to the invention, in the open position of the locking flap.
- FIG. 2 shows the socket in the molding position, seen from behind
- FIG. 3 represents a detail view, from above
- FIG. 4 shows a partial view of the isolated flap.
- the socket according to the exemplary embodiment described by way of non-limiting example comprises in known manner a tubular shaft (1) intended to receive the base of a light bulb, as well as a collar (2) on which press a seal not shown.
- the socket has two cells (3, 4) for receiving connection means.
- the first cell (3) is oriented perpendicular to the axis of the tubular shaft (1). It receives the electrical contact ensuring the supply via the drop of central tin at the end of the base of the lamp.
- the second cell (4) is oriented parallel to the axis of the tubular shaft (1). It is intended to receive the mass contact of the lamp and opens into the shaft (1) by a peripheral groove.
- the sleeve comprises a flap (5) folding.
- This flap has a bottom (6) whose inner surface is defined to fit on a lower portion (7) of the sleeve, when in the folded position.
- This bottom is extended laterally by a portion (8) covering the opening of the cell (4).
- the edge of this part (8) is supported by a seal (9) on through which a ground wire (10), or the ground wires, passes when one or more return wires are provided.
- a front portion (11) of the flap has a slot (12) in the axis of the cell (3), for the passage of a supply wire (13) passing through a seal (14) engaged in said cavity ( 3).
- the articulation of the flap (5) is provided by two lateral extensions (17, 18) constituting the pivots.
- Figure 2 shows the sleeve in molding position, seen from behind and Figure 3 shows a detail view from above.
- Figure 4 shows a detail view of the isolated flap of the rest of the socket.
- the sleeve is made by molding using a mold with two opposite movable drawers, perpendicular to the main molding axis.
- the molding produces a single piece, including the cylindrical barrel with its cells and the collar and the inner technical part of the cylindrical barrel, and the flap and the extension forming pivot, without contact between the flap and its extensions on the one hand, and the cylindrical barrel on the other hand.
- these two parts are connected temporarily by bonds of breakable material during the first manipulation.
- the drawers define a free space surrounding the extensions forming pivots.
- the extensions (17, 18) have a rectangular section because of their manufacture by molding with two movable drawers. The details of these extensions are shown in Figure 4.
- the extensions (17, 18) have at their ends (19, 20) ribs (23, 24) reducing the play with the complementary bearings (21, 22).
- Each bearing (21, 22) has a cavity in which the extensions (17, 18) are pivotable. This cavity is of generally cubic shape. It is delimited by a floor (25, 26), a side flank (27, 28), a ceiling (29, 30) and a bottom (31, 32).
- the sleeve further has one or more closures (33, 34) molded by a molding finger oriented in the main direction of molding and a finger coming perpendicularly below the bottom of the flap (6) along the bottom surface of the sleeve (7).
