[Prior Art] Conventionally, in this type of self-locking terminal device, the terminal device main body (hereinafter referred to as the main body) and the lid body are fixed together with a fixing screw, and this is further fixed with another mounting screw. Therefore, it is usually fixed to the surface to which it is attached. In this case, the fixing screws that fix the main body and the lid increase the number of parts, so
As shown in Figures 1 and 4 of Publication No. 134686, the base and cover are fastened together to the mounting frame using mounting screws, and the fixing screws for fixing the base and cover are eliminated. It is shown.

However, the former conventional example, namely Jitsukaisho
In the product of Publication No. 52-134686, it is necessary to assemble the connection terminal for electrical connection and locking of the electric wire, the blade holder spring, the locking spring, etc. at the same time as the installation to the mounting frame. Depending on the structure of the mounting frame or the case where the mounting frame has been previously installed in another location, there is a problem that the assembly work becomes extremely complicated. In addition, in the case of the latter Japanese Patent Publication No. 55-6990, although it has the advantage of being able to be assembled at any location, the fixing screws are simply replaced by the frame, so there is no hope that it will reduce the number of parts. Can not.

In the self-locking terminal device of this invention, the engaging portion and the engaged portion are each integrally provided on the main body or the lid, so the main body and the lid can be connected without using separate fastening members. It can be fixed and the number of parts can be reduced. Moreover, this fixing work can be performed regardless of the existence of the part to which the terminal device is attached, so there is no problem in assembling the locking spring and other members housed in the main body.
Allows assembly at any location. Furthermore, since the engaging portion and the engaged portion are formed on the outer wall of the main body or the lid, the structure of the mold for molding is simplified. To make molding work easier. Furthermore, the engagement structure can be constructed using only the thickness of the outer wall, and the size can be reduced.

An embodiment of this invention will be described below with reference to the drawings. Reference numeral 1 denotes a box-shaped main body made of thermosetting resin such as phenol resin, which is open at the back, and has a terminal chamber 2 inside, and a pair of engaged parts 3 formed in the shape of cut-out holes on the side wall. It is formed in one piece. Reference numeral 4 denotes two pairs of wire insertion holes that communicate with the terminal chamber 2 from the front surface of the main body 1, and are used for a pair of wire feed lines.
Reference numeral 5 denotes a disconnection hole formed in the main body 1, which penetrates from the terminal chamber 2 to the outer surface of the main body 1. Reference numeral 6 is a chain spring formed by bending a leaf spring, and is housed in the terminal chamber 2 together with a conductive plate to be described later. Reference numeral 7 denotes a mounting hole that is formed to penetrate approximately the center of the main body 1. Reference numeral 8 denotes a lid, which is made of an elastic thermoplastic resin such as nylon and shaped to fit into the rear opening of the terminal chamber 2. Reference numeral 9 denotes a pair of engaging portions protruding from both sides of the lid body 8, and a hook portion 10 that engages with the engaged portion 3 of the main body 1 is formed at the tip. A through hole 11 is formed in. Reference numeral 12 denotes a release button, which is formed integrally with the lid body 8. The tip of the release button 12 is exposed through the connection release hole 5 and is opposed to the lock spring 6. 13 is a conductive plate,
An internal wiring terminal is formed at the end to connect internal wiring of a lighting fixture or the like. Also, this conductive plate 13
is bent to accommodate the locking spring 6, and is accommodated in the terminal chamber 2 of the main body 1 with the locking spring accommodated therein. In this state, the hook portion 10 of the engaging portion 9 of the lid body 8 is slid toward the front side from the inside of the main body 1, thereby elastically engaging the engaged portion 3. The body 8 is temporarily fixed by closing the back surface of the main body 1. In this state, the hook portion 10 of the engaging portion 9 and the engaged portion 3 of the main body 1 have a play of approximately 0.5 mm to facilitate engagement.
Although the main body 1 and the lid 8 are not completely fixed, the internal locking spring 6 and the conductive plate 13 are kept in approximately predetermined positions until they are fixed to the attached part 15 such as a lighting fixture. It fulfills its role and constitutes one intermediate part. 14 is the temporarily fixed main body 1
This is a mounting screw for tightening and fixing the lid body 8 and the lid body 8 to an attached part 15 such as a main body (not shown) of a lighting device. Note that the thickness of the lid 8 is such that when it is securely fixed to the back of the main body 1, it is on the same level as the back of the main body 1 or is thicker than the back of the main body 1.
It is set to protrude by about 0.3mm.

For the terminal device configured as above,
After inserting the mounting screws 14 into the mounting hole 7 of the main body 1 and the through hole 11 of the lid 8, the mounting screws 14 are tightened to the mounted part 15, so that the main body 1 and the lid 8 are completely fixed to the mounted part 15. The looseness is completely eliminated, and the locking spring 6 and the conductive plate 13 are reliably held in the predetermined positions of the main body 1. In particular, if the back surface of the lid body 8 is designed to protrude from the back surface of the main body 1, the back surface of the main body 1 will be slightly higher than the attached part 15, and the main body 1
The looseness of the lid body 8 is completely eliminated. When a wire (not shown) is inserted through the wire insertion hole 4 in this state, it is locked and connected between the conductive plate 13 of the locking spring 6, but the locking spring 6 and the conductive plate 13 are Since they are reliably held in position, there is no possibility that they will work back and forth and make the connection uncertain. Similarly, when canceling the connection, insert a screwdriver or the like into the connection release hole 5 and press the release button 12 to ensure that the locking spring is elastically deformed by a predetermined dimension to easily release the connection. Can be done. In addition, since the main body 1 is made of thermosetting resin and the lid 8 is made of thermoplastic resin, the main body 1 housing the electric wire connection part is not susceptible to deformation due to heat, etc., which is the property of thermosetting resin. By taking advantage of the elasticity of the thermoplastic resin, the lid 8 can easily form the engaging part 9, and when the back of the lid 8 is made to protrude from the back of the main body 1, it is possible to easily form the engaging part 9 when tightening the mounting screw 14. This prevents an accident in which the lid body 8 receives the tightening pressure and the brittle thermosetting resin body 1 breaks.

Furthermore, in the above embodiment, the mounting screw 14 is inserted from the front side of the main body 1, but depending on the structure of the lighting equipment, the mounting screw 14 may be inserted into the main body 1 through the mounting screw 14.
You can also insert it from the back side. In this case, it is convenient to form a protruding portion for preventing rotation of the nut on the front side of the main body 1. Alternatively, a tatupin screw or the like may be used.

Since this invention is constructed as described above, there is no need for a special fastener between the main body and the lid, and the number of parts can be reduced. In addition, the assembly can be performed at any location, improving work efficiency, and is easy to manufacture and can be expected to be miniaturized.
