Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an insertion plug used for power supply to a tape electric wire to which a large number of small light bulbs are attached.

A tape electric wire is a thin tape-shaped electric wire made by sandwiching two thin copper wires between two plastic tapes, and cannot be connected with a commonly used cord plug.

Even if it were possible to expose the thin copper wire and connect it to the power supply terminal, the connection between the tape wire and the plug would be unstable, and the connection strength would be extremely weak and would easily tear off, making it practically unusable. Can not.

The present invention is an insertion plug exclusively for tape electric wires, and its purpose is to provide an insertion plug with stable connection and extremely strong connection strength.

The present invention, which was made in order to achieve this objective, consists of a pair of covers made of plastic and a pair of terminals made of metal. One cover is provided with a protrusion that protrudes beyond the mating surface, and the other cover is provided with a recess into which the protrusion fits, and a fixing hole is inserted through the protrusion and recess. The pair of terminals have an engaging recess in the middle part and a protruding part at the rear end, so that when the tape electric wire is held between the mating surfaces of the two force bars, the protruding part An insertion plug for a tape electric wire, which fits into a through-hole of the tape electric wire, and has a protruding part of each terminal that comes into contact with an exposed part of the tape electric wire and is pressed and deformed to hold the tape electric wire, and the plug includes a pair of covers. At the same time, the tape electric wire is held between the tape electric wires, the protrusion fits into the through hole of the tape electric wire, and the overhanging portion of the terminal comes into contact with the thin copper wire and is compressed and deformed, thereby preventing the connection between the tape electric wire and the plug. Not only will it become stable and strong,
No poor contact occurs between the thin copper wire and the terminal.

Next, the present invention will be explained in more detail with reference to the illustrated embodiment. The plug is composed of a pair of covers 1 and 2 made of plastic and a pair of terminals 3 and 4 made of metal.

This plug is used exclusively for the tape electric wire 5, and the tape electric wire has a structure in which thin copper wires 6 and 7 are sandwiched between two pieces of soft tape and are arranged approximately parallel to each other at an appropriate interval. , a plurality of through holes 8 are provided in the center at appropriate intervals in the length direction, and elongated holes 9 and 10 are formed adjacent to both sides of the through holes and only in one tape to form copper thin wires 6 and 7. so that it is exposed (this is a form of power).

Then, lead wires for small light bulbs are attached to the exposed portions of the thin copper wires 6 and 1, and a large number of light bulbs are attached to the tape electric wire to be used as indoor decorative lighting.

One of the covers 1 is shown in FIG. 2A.

As shown in the figure, a protrusion 11 is provided on the mating surface side that protrudes beyond the mating surface, and a fixing hole 12 and a screw hole 13 are provided through the protrusion, and both sides of the protrusion and the insertion tip side are provided. A groove portion 14a parallel to the end portion of the groove portion 14a.

14b, 15a, and 15b are provided.

The other cover 2 is provided with a recess 21 at a position corresponding to the protrusion 11, as shown in FIG. , grooves 24a and 24b having substantially the same shape as the grooves of the one cover on both sides of this recess.

25a and 25b are provided.

However, the groove portion 24a. 25a is a rectangular concave portion surrounding the circumferential surface.

The terminals 3 and 4 have the same shape, each having a retaining recess 31 and 41 formed in the middle part, and having a slender rear end and a protruding part 32 and 42 formed at the rear end, respectively. has been done.

In the plug configured in this way, the tape electric wire 5
When installing the tape wire 5 for power supply, cut the tape wire 5 to an appropriate length, and insert a guide hole, for example, into the end of the connection side to the plug so that the through hole 8 goes into the plug and is hidden. 5a and sb are provided, and one side of this guide hole 5b
The tape wire 5 can be cut off and the end inserted into the plug, and the protrusion 11 of one cover 1 can be fitted into the through hole 8 to prevent the tape wire 5 from being pulled out. Overhang part 3
2.42 comes into contact with the exposed copper thin wires 6 and 7 to conduct electricity, and when the two force bars 1 and 2 are combined with the screw 26 through the screw hole 23, the protrusion 11 of one cover It fits into the recess 21 of the other cover, and at the same time, the protruding parts 32 and 42 provided at the rear ends of the terminals 3 and 4 press the tape electric wire 5, and the thin copper wire 6°7 is pushed and bent into the grooves 24a and 25a. The patient is seated and immobilized.

Therefore, the insertion plug and the tape electric wire are separated by the fitting between the protrusion 11 and the through hole 8, the suppressed deformation by the protrusion 32, 42 provided at the rear end of the terminal, and the clamping pressure between the force bars. The connection becomes stable and extremely strong.

The fixing holes 12 and 22 are used when fixing the plug to a wall or the like.

As explained above, in the tape electric wire insertion plug according to the present invention, the electric wire itself has a thin tape shape, and such a thin electric wire is held between a pair of covers, and the protrusion provided on the cover is inserted into the through-hole provided in the tape electric wire, and furthermore, the contact between the terminal and the thin copper wire that constitutes the current-carrying circuit is formed by making contact with the overhang provided at the rear end of the terminal, and the two force bars are combined. The protruding part pushes the thin copper wire into the groove and deforms it, further increasing the pressure contact force, eliminating contact failures, and making the clamping force stronger, making the connection between the plug and the tape wire extremely stable. It has this excellent effect.
