Abstract

(57) [Summary] [Structure] A pair of terminal plates 9 and 10 are fitted into the terminal plate engaging grooves 5d, 5e, 5f and 5g of the terminal plate holding member 5, and these are inserted into the cylindrical body 2. From above, the bulb holder 3 to which the bulb 7 is attached is pushed in to electrically connect the conductors 7a and 7b of the bulb 7 to the terminal plates 9 and 10. Furthermore, a decorative shade 6 was attached to the upper part of the cylindrical body 2 to form the decorative electric light socket 1. [Advantages] The tapered outer surfaces 5h and 5i of the terminal plate holding member 5 abut the tapered inner surfaces 2g and 2h of the tubular body 2, and the terminal plates 9 and 1
Since 0 is sandwiched in the tubular body 2 via the terminal plate holding member 5, the terminal plates 9, 10 are used when the light bulb receiver 3 is pulled out from the tubular body 2.
Does not come off. Further, since the terminal plates 9 and 10 are separated by the partition wall 5c, there is no possibility that the terminal plates 9 and 10 and the bare wires 12a and 13a of the cords 12 and 13 are short-circuited to cause an electric leakage fire. Further, since the terminal plate holding member 5 fills the gap between the cylindrical body 2 and the light bulb receiver 3, rainwater or the like does not enter even when used outdoors.

In addition, substantially rectangular rod-shaped locking members 2c and 2d are horizontally projected below the respective protrusions 2a and 2b in FIG. On the other hand, as shown in FIGS. 1 and 4, on the inner peripheral surface of the cylindrical body 2, two convex portions 2e and 2f are vertically provided at equal angular intervals (that is, 180 ° intervals). Two planar tapered inner surfaces 2g and 2h are formed on the inner surface of the taper so as to be opposed to each other such that the distance between them becomes shorter as it goes down in FIG.

Further, the terminal plate holding member 5 is a pair of holding pieces 5a, 5b formed in a substantially semi-cylindrical shape, which are opposed to each other with a partition wall 5c therebetween, and one holding piece 5a has terminals. The plate engaging grooves 5d and 5e are formed, and the other holding piece 5b is formed with terminal plate engaging grooves 5f and 5g. As shown in FIG. 3, the terminal plate 9 attached to the bare wire 12a at the tip of the cord 12 is engaged with the two terminal plate engaging grooves 5d and 5f, and the remaining two terminal plates are engaged. The terminal plate 10 attached to the bare wire 13a at the tip of the cord 13 is engaged with the engaging grooves 5e and 5g. In addition, on the outer peripheral surface of each holding piece 5a, 5b of the terminal plate holding member 5, first concave portions 5j, 5k capable of engaging with the convex portions 2e, 2f of the above-mentioned cylindrical body 2 are equiangularly spaced (that is, , 180 ° apart) and two planar taper outer surfaces 5h, 5i are formed, and the distance between these tapered outer surfaces 5h, 5i becomes shorter as it goes downward in FIG. ing.

Further, on the outer peripheral surface of the substantially cylindrical light bulb receiver 3, second concave portions 3a and 3b capable of engaging with the convex portions 2e and 2f of the cylindrical body 2 are equiangularly spaced (that is, , 180 ° apart), and two rectangular pillar-shaped legs 3c and 3d are provided in the lower part of the light bulb receiver 3, and as shown in FIG. 2, the terminals are provided between these legs 3c and 3d. The partition wall 5c of the plate holding member 5 is provided so as to form a space 3e into which the partition wall 5c can be fitted. Further, as shown in FIGS. 1 and 2, an electric bulb 7 is attached to the light bulb receiver 3 in such a manner that the two conducting wires 7a and 7b thereof are projected outward from the lower end surfaces of the leg portions 3c and 3d, respectively. ing.

Further, at the lower portion of the inner peripheral surface of the substantially cylindrical decoration shade 6 having a predetermined decorative shape on the outer peripheral portion in FIG. They are arranged symmetrically, and openings 6c, 6d are formed between these tapered stepped portions 6a, 6b.

Since the decorative light socket 1 according to the present invention has the above-described structure, when the decorative light socket 1 is assembled, first, the bare wires 12a and 13a at the ends of the cords 12 and 13 are attached. With the installed terminal boards 9 and 10 engaged with the terminal board engaging grooves 5d, 5f, 5e and 5g of the terminal board holding member 5, the terminal board is provided with a predetermined pressing jig (not shown). The holding member 5 is inserted into the tubular body 2 by pushing it downward from above in FIG. Then, the tapered outer surfaces 5h and 5i of the terminal plate holding member 5 come into contact with the tapered inner surfaces 2g and 2h of the cylindrical body 2, so that the terminal plates 9 and 10 are inserted into the cylindrical body 2 through the terminal plate holding member 5. It is firmly held in a sandwiched form. At this time, by inserting the first concave portions 5j, 5k of the terminal plate holding member 5 into the convex portions 2e, 2f of the tubular body 2, the terminal plate holding member 5 is inserted into the tubular body 2. Can be executed smoothly.

After that, the light bulb receiver 3 having the light bulb 7 mounted therein is inserted into the cylindrical body 2, and the partition wall 5c of the terminal plate holding member 5 is fitted between the leg portions 3c and 3d of the light bulb receiver 3. Then, the lead wires 7a and 7b of the light bulb 7 come into contact with the terminal plates 9 and 10 to be electrically connected. At this time, by engaging the second concave portions 3a, 3b of the light bulb receiver 3 with the convex portions 2e, 2f of the cylindrical body 2, the insertion of the light bulb receiver 3 into the cylindrical body 2 is smoothly performed. You can do it.

Next, the openings 6c and 6d of the decorative shade 6 are aligned with the positions of the protrusions 2a and 2b of the cylindrical body 2, and in this state, the decorative shade 6 is brought into contact with the locking members 2c and 2d of the cylindrical body 2. It is lowered until it touches, and then the decoration shade 6 is rotated. Then, the tapered stepped portions 6a and 6b of the decorative shade 6 are sandwiched between the locking members 2c and 2d of the cylindrical body 2 and the protrusions 2a and 2b. As a result, even if a force acts on the decoration shade 6 for some reason, the decoration shade 6 will not be easily removed. When removing the ornamental shade 6 attached in this way from the cylindrical body 2, the detaching work can be easily performed by the reverse procedure, so that the ornamental shade 6 can be easily replaced.

Here, the assembling work of the decorative electric light socket 1 is completed, but the decorative electric light socket 1 thus assembled is extremely safe.

That is, since the terminal plates 9 and 10 are firmly held in the cylindrical body 2 via the terminal plate holding member 5, as already described, when the bulb holder 3 is pulled out from the cylindrical body 2. It is possible to prevent the occurrence of the situation where the terminal plates 9 and 10 come off together with the light bulb receiver 3. Further, as shown in FIG. 3, the terminal plates 9 and 10 are separated by a partition wall 5c located in the middle of them, so that they are connected to the terminal plates 9 and 10 (or the terminal plates 9 and 10, respectively). There is no risk of short-circuiting the bare wires 12a, 13a) of the cords 12, 13 and causing a short circuit fire. Further, as shown in FIGS. 2 and 3, the terminal plate holding member 5 is interposed between the cylindrical body 2 and the light bulb receiver 3 so as to fill the gap therebetween, so that the terminal plate holding member 5 is used outdoors. However, it can prevent rainwater from entering.

In the above-described embodiment, the decorative electric light socket 1 having the decorative shade 6 has been described, but the decorative shade 6 may be omitted when the decorative light socket 1 is used for an application where decorativeness is not required. .
