Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a wiring device, and relates, for example, to a connection between a terminal and an electric wire in a device such as a lamp socket.

[Technical background of the invention]

In conventional wiring devices of this type, in order to connect an electric wire to a terminal, a core wire of the electric wire, which has been cut to a predetermined length in advance, is connected to an electric wire connection portion of the terminal. In this conventional configuration, when the wire connection work is automatically performed by a machine, the work of positioning the tip of the wire by the machine at the wire connection part of the terminal is difficult because the wire is flexible and easily bends. It is difficult to automate, and the mechanization of semi-automatic work has been limited, such as manually aligning the electric wire to the position of the terminal's electrical contact point and using this foreshadowing to tighten the terminal screw or solder using a machine.

[Purpose of the invention]

The present invention has been made in view of the above points, and it is possible to
To provide an electric wire device that can connect a terminal and an electric wire simply by inserting it into a wiring groove of a device body, and can easily automate electric connection work.

[Summary of the invention]

The structure of the present invention is such that a wiring groove is formed on one surface of an insulating container body such as a lighting tube socket, and a wiring groove leading from -[w to the other end 1iiK is formed, and the wiring groove is exposed to the wire connection portion of a terminal provided on the container body. This is a book in which the wire is inserted into the wiring groove so that the wire is positioned at the wire connection part of the terminal.

[Embodiments of the invention]

Next, the structure of an embodiment of the present invention will be explained with reference to the drawings of FIGS. 1 to 8 of the lighting tube socket.

(11 is the insulating container body of the lighting tube socket, which is formed in a curved shape with an open back.The inner surface of this container (1) has a pair of contact piece holding grooves (21 (31 are formed facing each other) at both ends). A terminal arranging portion (4) is formed in communication with the outside II# of this negative side contact piece holding groove (2).

In addition, a mounting hole (51) is formed on the front surface of this container (1) for attaching this container (11).A pair of locking holes (61 (61) are formed concentrically with this mounting hole (5) in between. is formed, and a contact bottle insertion part (7) for a lighting tube (not shown) is formed at one end of this locking hole (61) by expanding its width. A lighting tube fitting cylinder part (8) is integrally formed surrounding 61+61.

In addition, a terminal block 1t (9) is integrally formed on the front side of this container (1), and this terminal block 5 (9) has a terminal block (1t) attached to the container (1
A wiring groove aS leading from one end 11 (1- to the other end surface (IJ) of 1) is forward I4[1, and this wiring groove tto communicates with the terminal arrangement part (4)K. Wiring grooves (110) are narrowed by forming openings facing each other at both ends thereof.

Furthermore, a recess Q is formed in the center of the terminal block portion (9) of the container (1), intersecting with the wiring groove (II).

Next K (1:3 (13 is a pair of contact pieces, the said vessel (
1) Contact piece holding groove +21 (Both ends are held and held by 31, locking hole 16) (6) K is inserted and the terminal pin of the locked lamp is contacted.

Also, this pair of contact pieces 031 (-74K of 13 is the terminal f
ill (14) are each formed integrally, and this terminal shaft row is formed with an electric wire connection part (19).
The connection part (lS is a connection having a width narrower than the diameter of the core of the electric wire 08!!al) which is continuously and gradually pinched by the wire guide part which is opened in a widened shape at the front edge of the terminal 14 (18). Groove CaK″C
It is formed. Then, the contact piece α3 (13) is connected to the container body (11
Contact piece holding #I (21+31K) Terminal (1#I is placed in terminal placement part (4) K of container body (1),
The connection groove (2) of the wire connection part Q9 of the terminal (14Ia4 is 4
The body ill is exposed to the layout m5no with an opening toward the front opening direction of the layout #QI.

In addition, the contact piece ill fi3 is the contact piece holding groove +21 +3
1 and is held by a back plate (not shown) which is fitted onto the rear opening edge of the container body (1) and welded or bonded.

Next, the phone #111i of this example! I will explain how to connect the electric wire 4wJK.As shown, grab the hook side of the electric wire aa with the chuck Gin''C of the electric wire 1 and pull it out.Furthermore, at a predetermined interval, grab the electric wire 41i1QI with the chuck (2) of the electric wire 41i1QI and pull it out. Pull both chucks Qll- in the direction away from each other with 9 volts g.
In this state, move the wire member or the equipment body (1) to the position of the mass body (1), and then wire the electric wire Im (2). Insert it into the groove, and in this state, use the jig V3g3 to peel off the vicinity of the mold clamping connection aS of the terminal grade thickener of <tWO・ with the opening edge (2) of #It■ to expose the core wire α9, The core wire a9 is press-fitted into the connection groove (to), and the wire 〇 shelf is connected to the terminal [141 (I4).

Next, the portion exposed in the recess α3 of the body m of the electric QJI is cut with a cutting tool. Furthermore, this cutting tool (to)
is shaped like scissors, with cutting blades on both sides.

Next, the electric wire a1 is held at an appropriate length and cut, thereby completing the connection of the electric wire Q8.

Next, another embodiment will be described with reference to drawings O6w:J to ':JP1.

The electrical connection 09 of the terminal a4 is formed into two folded pieces -〇υ, and one piece S is opened toward the opening direction of the wiring groove a and has a cutting groove at the edge. aat-, and in the other piece IB61, a wiring groove (as f) is formed in the wiring groove (IiI groove) which opens toward the sm opening and has a width narrower than the diameter of the core wire a facing the electric wire. Adjacent to the cutting groove (to).

The cutting groove shall be narrower than the groove.

In this configuration, the electric wire O1 is cut at the same time as the electric wire O1 is connected to the connection groove K of the terminal Q41, and a cutting tool (E) is not required, so that work efficiency can be improved.

Furthermore, the present invention is not limited to lighting tube sockets;
Applicable to various wiring devices.

〔Effect of the invention〕

According to this @, from one side to the other end thiK
We formed a wiring groove that communicates, and let the electric wire connection part of the terminal provided on the container body come out from this wiring groove, so that we can grasp the flexible electric wire and connect it to the electric IW connection of the terminal. There is no need for positioning, and the wire can be easily connected to the terminal by inserting the wire under tension into the wiring groove of the device, and the wire connection work can be easily automated and mechanized.

By forming the wire connection portion of the terminal in a connection groove having a width narrower than the wire diameter of the wire, it is possible to improve the efficiency of the wire connection work by simply pushing the wire.

Also, a recess S7 intersecting the wiring groove between at least one pair of terminals.
By forming the wire, wires can be connected and cut to multiple terminals at the same time, thereby improving work efficiency.

Further, by forming a cutting groove in the vicinity of the *a groove in the wire connection portion of the terminal, the step of cutting the wire can be omitted.
