Description

[Detailed description of the invention] This invention relates to a light bulb socket, which allows easy connection of electric wires and is suitable as a socket for arranging a large number of light bulbs in parallel, such as stage lighting bulbs. It's something to do.

All conventional sockets are arranged by connecting the cut ends of electric wires to respective terminals as shown in FIG.

Therefore, in order to connect many light bulbs in parallel, the wires must be cut.
It is necessary to connect the core wires of each cut electric wire to each adjacent socket, which makes the connection work extremely time consuming and inefficient.

Therefore, the present invention can eliminate the above-mentioned drawbacks and connect a series of electric wires.Hereinafter, the details of the present invention will be explained with reference to the illustrated embodiments.

The present socket S shown in FIG. 1 has U-shaped terminal fittings 3, 3 disposed facing each other with their openings facing outward in notches 2, 2 provided on opposite sides of the back surface of a socket body 1. As shown in Fig. 2, the terminal fitting 3 has the clamping pieces 3a*3b bent and facing each other to form a flexible clamping piece 3at3b, and the screw insertion hole 3c is formed in the outer clamping piece 3a to form the inner clamping piece. A screw hole 3d is formed in 3b, and a screw 7 is provided.

Then, one of the metal fittings 3 is integrally connected and fixed to the light bulb insertion screw tube 4 at its bent base side via a bolt 6', and the other terminal metal fitting 3 is attached to its bent base side by a central contact tongue. The piece 5 and the mounting are integrally connected and fixed via bolts 6 (see Fig. 3).

Furthermore, the notches 2, 2 of the socket body 1 are provided with terminal fittings 3, 3.
An insertion recess 8 that can accommodate the tip of the screw 7.
8 is formed.

Incidentally, a mounting hole 9 provided in the bent base of the terminal fitting 3 is an insertion groove for a bolt 6.6'.

Since this example is configured as described above, a series of wires with the insulation coating peeled off only at the connection part is used, and the peeled core wire D
After horizontally inserting a into the terminal fitting 3 from the opening side, by tightening the screw 7 of the fitting 3, the core wire Da is sandwiched between the clamping pieces 3a and 3b between the bolts 6, 6' and the screw 7. The connection wiring is done (see Figures 3 and 4).

In this state, the clamping piece 3a is slightly bent and pressed, so that the core wire is strongly tightened between the clamping pieces 3a and 3b and does not come off.

At this time, even if the tip of the screw 7 protrudes, since the recess 8 is provided on the opposite surface, the core wire can be tightened without any problem.

Therefore, according to this example, wiring connections can be made extremely easily.

The mounting of the socket S in this example is the same as the conventional one, and as shown in FIG. 5, the mounting seat 10 is integrally formed on the socket body 1.
This is tightened and fixed to the mounting plate 11 with bolts and nuts through the packing opening.

Additionally, safety is provided by covering the back of each socket with a series of gutter-like covers (not shown) after each socket is wired.

The present invention is not limited to the embodiments, and the essential feature of the present invention is to attach a flexible terminal fitting having a U-shape by bending the clamping pieces to face each other, and attaching the socket to the socket with the opening side facing outward. At the same time, the terminal fitting is connected and fixed to the light bulb insertion screw tube and the central contact tongue piece on the bent base side via bolts, and the opening of the terminal fitting is arranged to face the notch provided on the back side of the A screw insertion hole is provided in the outer clamping piece on the side, and a screw hole is provided in the inner clamping piece, and for tightening, screw the screw from the insertion hole into the screw hole, and prepare it on the opening side of each terminal fitting. This is a tree bark in which an insertion recess for accommodating the tip of the socket is formed in the notch of the socket body.

Therefore, according to the present invention, there is no need for the time-consuming process of cutting the wire and connecting the separated ends as in the past, and the connection can be made extremely easily by simply inserting the core wire and tightening the screw, and the wire can be connected in a series. It is a practical idea that has the great effect of allowing quick wiring work as a socket used when arranging a large number of light bulbs from a trowel that can connect electric wires.
