Description

[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to a fluorescent lamp socket, particularly to the improvement of the terminal portion.

B. Prior Art Conventionally, the locking part of a fluorescent lamp socket has two wire locking notches so that it can be used for either a single lamp circuit or multiple lamp circuits. The locking piece body is constructed by drilling two wire insertion holes, each corresponding to the wire locking notch, and can be used by inserting one or two wires into the locking notch of the locking part as necessary. This is what I did.

C. Problems that the invention aims to solve As mentioned above, the prior art can be evaluated as a invention in that it has compatibility in that it can be used in both single lamp circuits and multi-lamp circuits with one socket. In this case, the wire is inserted into the locking notch on one side of the locking part, which causes the locking part to become distorted and the wires cannot always make proper electrical contact. ,
There are drawbacks such as when releasing one of the inserted wires, the other wire must also be released at the same time.

D. Means for solving the problems The present invention employs the following means to solve the problems of the prior art as described above.

That is, the lock part of the conductive piece is divided in half by a slit in the center to form two lock pieces, and the means for locking the conductive piece to the piece is to lock the lock part halfway through the slit of the lock piece. constituting a connection, and further protruding from the center of the retaining groove of the piece body into which the slit fits;
Furthermore, a locking piece is inserted into the locking groove formed by cutting out a part of the end surface of the convex strip, and the locking piece is inserted from the piece body by fitting the locking connection into the locking groove. The structure is such that it cannot be pulled out.

E. Example Consists of a conductive piece 1, a bridge body 4, a case 5, and a receiving plate 6.

The conductive piece 1 is a highly elastic band-shaped conductor made of phosphor bronze or other suitable material (new metal).

The shape is such that one end is bent at an acute angle into an inverted V-shape, and this is further divided into two by a slit S from the center of the bent end, through the top of the bend, and the other side to form two lock pieces 1A and 1B. And each lock piece 1A, 1B
An electric wire locking cut 3 is made at the end, and a locking connection 2 is formed in the middle of the slit S near the top of the bend.

The bent end of the locking part is bent to the horizontal bending surface 1C,
This end portion is further bent upward, and this end portion is further bent horizontally to form the lamp pin contact surface 1D.

The piece body 4 is formed into an L-shaped side surface, and the entire body is formed of an insulating material so that the height and width thereof can be accommodated in the case 5.

A pair of holding grooves 4A are formed on the inside of the vertical surface,
A lateral groove 4B is formed on the horizontal surface perpendicularly to the holding groove 4A, and a communication portion between the holding groove 4A and the lateral groove 4B is formed in the cavity 4.
Make it E.

Further, a protruding strip 4C is provided in the center of the holding groove 4A to divide the holding groove 4A into two sections.

A part of the end surface of the protrusion 4C is cut out to form a locking groove 4.
D is formed, and two electric wire insertion holes 4H and two release holes PH are formed on the side surface of the piece body 4, extending over the contact cavity 4E, corresponding to each of the pair of retaining grooves 4A divided into two strips.

The case 5 is made of an insulating material, has a semicircular top, and has a circular hole 5A formed along it.
Make an opening 5B on the other side.

The receiving plate 6 is formed of an insulating material, and has a pair of pin holes 6H formed on its surface that match the lamp pins, and has a shape that matches the back side of the circular hole 5A of the case 5.

To assemble the parts configured as described above, first, the locking pieces 1A and 1B of the conductive piece 1 are connected to the holding groove 4A of the piece body 4.
The protruding strip 4C is fitted into the slit S, the locking connection 2 of the slit is fitted and locked into the locking groove 4D on the end face of the holding groove, and the contact surface 1D of the conductive piece 1 is fitted with the receiving plate 6. Place the pin hole 6H in position and place it inside the case 5 through the opening 5B in that state.The receiving plate 6 is applied to the back side of the circular hole 5A, and the spring force of the conductive piece 1 constantly presses the piece. Wire insertion hole 4H and release hole PH of body 4
is exposed to the outside through the opening 5B of the case to complete the assembly.

To use the socket with the above configuration, in the case of a circuit with one fluorescent lamp, insert the electric wire L into one of the two locking pieces 1A and 1B of the socket, one on the 1A side, and lock the locking piece. The electric wire is press-fitted into the notch 3, and resistance is applied in the direction in which the electric wire L is pulled out, thereby preventing the electric wire L from being pulled out, as in the conventional method.

In addition, when pulling out the electric wire L, insert a tool such as a screwdriver through the release hole PH, push down the lock piece 1A on the wire locking side to release the lock on the wire, and then pull out the wire from the socket. .

If the fluorescent lamp has multiple circuits, connect the electric wire L to the locking notch 3 of the two locking pieces 1A and 1B of the socket.
The electric wire L is connected to a plurality of circuits by press-fitting and locking the wire.

If it is necessary to pull out one wire L,
Insert a screwdriver into the corresponding release hole PH to release it.

Since the present invention is constructed as described above, it can be used whether the fluorescent lamp is connected to a single circuit or to multiple circuits, and furthermore, when used in multiple circuits,
Even when one electric wire is pulled out, the function can be canceled regardless of the other electric wire.

When locking the conductive piece to the lock piece, the lock can be easily and reliably locked by simply locking the locking connection provided in the slit of the lock piece into the locking groove of the piece. exhibits.

The tip of the lock piece is located in the cavity of the piece body, and the piece body has a wire insertion hole and a release hole correspondingly, so that the lock piece can be opened by inserting the wire through the insertion hole. The wire is locked in the locking notch made at the end of the wire and is given resistance in the pulling direction, so the inserted wire is prevented from being pulled out accidentally.
When pulling out the electric wire, the electric wire can be easily pulled out by inserting a tool through the release hole and pushing down the locking piece to release the engagement between the electric wire and the locking piece.

In addition, since the horizontally bent surface of the conductive piece is fitted into the horizontal groove of the piece, even when the receiving plate is pushed into the case by a fluorescent lamp, the horizontally bent surface of the conductive piece is held by the horizontal groove, so it will not accidentally shift laterally. The spring force always acts to reliably press the receiving plate without twisting or twisting.

G. Effects Since the present invention is constructed as described above, firstly, the locking state of the bridge body and the conductive piece is reliable.

Secondly, since the lock piece is formed into two independent strips with slits, it is compatible with both single and multiple fluorescent lamp circuits. This is a practical device with excellent effects.
