JPH05190216A - Earthing terminal device - Google Patents

Abstract

PURPOSE:To enable complete earthing by inserting a metal rib, provided protrusively at an instrument body, into a pressure-holding insertion slit provided at an earthing terminal part. CONSTITUTION:A metal rib protrusively provided at an instrument body 3 is pressure-held into a pressure-holding insertion slit 6 provided at an earthing terminal part 2 protrusively provided inside or outside a terminal block body 1. Accordingly, even if the body 3 has the coated face 5, the coated face 5 is chipped by the tip of the insertion slit 6 to expose the metal face, and the metal face is brought into direct contact with the insertion slit 6, so that conduction is not impeded. The pressure-holding insertion slit 6 of this earthing terminal has resilience. As a result, even if a slight gap is generated between the terminal block body 1 and instrument body 3, the complete earthed state can be always maintained because of the metal rib 11 being inserted therein.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ground terminal device, and more particularly to a ground terminal used for lighting equipment and the like.

[0002]

2. Description of the Related Art FIGS. 5 and 6 show, for example, Japanese Patent Laid-Open No. 61-743.
It is sectional drawing which shows the conventional earth terminal shown by the 95 publication. In the figure, 1 is a terminal block body, 2 is a ground terminal portion, 3 is a tool body, and 4 is a ground terminal insertion hole provided in the tool body 3.

Next, the operation will be described. Insert the ground terminal 2 projecting from the terminal block body 1 into the ground terminal insertion hole 4 provided in the device body 3 and at the same time fix the terminal block body 1 to the device body 3 with a mounting screw or a mounting claw for grounding. I take it.

[0004]

Since the conventional ground terminal device is constructed as described above, when the terminal block body 1 is fixed by the mounting screw or the mounting claw, if some looseness is found, the ground terminal device is grounded. Terminal 2 and ground terminal insertion hole 4
Since there is a gap between and, there is a problem that it is unlikely that a perfect ground can be obtained.

The present invention has been made in order to solve the above problems, and an object thereof is to obtain a complete ground even if the terminal block body and the instrument body are slightly loosened. To do.

[0006]

In order to achieve the above object, a grounding terminal device according to the present invention has a grounding terminal portion provided in a terminal block body, with an insertion slit for press-contacting and clamping, and a grounding terminal device. The main configuration is that a metal rib is provided so as to face the insertion slit on the terminal block mounting surface side.

[0007]

In the grounding terminal device according to the present invention, since the metal rib projecting from the device body is inserted into the insertion slit for press-contacting and clamping provided in the grounding terminal portion, there is a slight gap between the terminal block body and the device body. Does not interfere with the grounding action.

【Example】

Example 1. An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a sectional view before assembly, FIG. 2 is a sectional view after assembly, and FIGS. 3 and 4 are perspective views showing an embodiment. The same parts as those of the conventional technique are designated by the same reference numerals, and the description thereof will be omitted. In the figure, 5 is a painted surface of the instrument body 3, and 6 is an insertion slit for press-contact sandwiching for grounding. There is a tapered insertion part 6a at the opening end and a circular groove 6b at the other end. It is easy to include. 7 is an electric wire, 8 is a claw for mounting the terminal block, 9 is a screw hole for mounting the terminal block, 10 is a screw for mounting the terminal block, 11 is a metal rib press-fitted in the insertion slit 6, and the instrument body 3 is punched out. It is a bent one.

Since it is constructed as described above, the ground terminal portion 2 projecting inside or outside the terminal block body 1 is provided.
The device main body 3 is inserted in the insertion slit 6 for press-contacting and clamping provided in the
Since the metal ribs 11 projecting from the surface are pressed and sandwiched, even if the instrument body 3 has the coating surface 5, the coating surface 5 is scraped by the tip of the insertion slit 6, and the metal surface is exposed. Since it is in close contact with the insertion slit 6 directly, conduction is not hindered. Since the insertion slit 6 for press-contacting and pinching of this ground terminal device has a spring property, even if there is a slight gap between the terminal block body 1 and the instrument body 3, the metal rib 1
Since 1 is sandwiched, it is possible to always maintain a perfect ground state.

Embodiment 2. Although only the ground terminal portion has been described in the above embodiment, FIG. 3 illustrates a structure for attaching the ground terminal device to the instrument body 3. The device body 3 (not shown) is provided with a mounting hole (not shown) of a claw, and at the same time when the mounting claw 8 is inserted into this mounting hole, the same operation as that of the above-described first embodiment is performed to maintain the grounded state. it can.

Embodiment 3. In the second embodiment, the attachment claws are used to attach the terminal block body 1 to the instrument body 3, but the terminal block body 1 is provided with the attachment screw holes 9 as shown in FIG. 4, and the attachment screw holes are provided. The instrument body 3 (not shown) may be sandwiched between the mounting screw 10 and the mounting screw 10 and the mounting screw 10 may be tightened. Even in this case, the same operation as in the first embodiment is performed.

[0012]

As described above, according to the present invention, the grounding terminal portion provided in the terminal block main body is formed with the insertion slit for press-contact clamping, and the insertion is made on the terminal block mounting surface side of the instrument main body. Since the metal ribs are provided so as to face the slits, even if some looseness occurs between the terminal block body and the instrument body, the metal ribs are pressed and clamped to the ground terminal portion, so a perfect grounding state is maintained. be able to.
