Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electrostatic shock preventer for preventing an electric shock shock to an occupant due to static electricity charged on a human body, and more particularly to a ground electrode that can be easily attached and can provide a reliable electrical connection.

[0002]

[Prior art and its problems]

 When an occupant such as a car is about to get off, static electricity may be discharged between the metal part of the car body, the paint part, etc. and the human body, causing a shock shock. This mainly occurs when an occupant gets off the vehicle from the vehicle and is peeled off from the vehicle seat, and this is discharged to the grounded vehicle body. As a countermeasure against this, for example, an electrostatic discharge preventer as disclosed in Japanese Utility Model Laid-Open No. 64-7,799 has been proposed. Conventionally, when taking antistatic earth on the body of an automobile, remove the inner lining of the automobile as shown in FIG. Alternatively, as disclosed in Japanese Utility Model Application Laid-Open No. 64-7799, adhesion was performed using a conductive adhesive tape. However, co-tightening requires a tool, which reduces workability.In the case of conductive adhesive tape, peeling of the tape or conductive part may occur depending on whether the screw head is protruding from the panel or not. There is a problem that it is easy to wake up. An object of the present invention is to provide a ground electrode for an electrostatic shock preventer, which is easy to install and enables reliable electrical connection.

[0003]

[Means for Solving the Problems]

 In order to achieve the above object, the earth electrode for an electrostatic shock protector of the present invention comprises an earth electrode board electrically connected to an electrostatic shock protector installed in a vehicle, and the earth electrode board is connected to the car body. The electrode is provided so as to be deformable so as to be in contact with the earth point, and the earth electrode substrate around the electrode is provided with a fixing member for attaching to the panel surface around the earth point.

[0004]

[Action]

 For example, when a tightening screw of an automobile part is used as a ground point, the electrode of the ground electrode substrate is brought into contact with the screw head, and the ground electrode substrate is fixed to the panel surface around the screw. Then, the electrode is pushed by the screw head and deforms, making sure contact and grounding.

[0005]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows the external structure of the ground electrode, and FIG. 2 shows the cross-sectional structure of the ground electrode. The ground electrode 1 has a deformable electrode 3 made of a conductive fiber fixed to a substantially center of a ground electrode substrate 2 with a conductive adhesive 4. The ground electrode is attached to a body ground portion of an automobile around the electrode. Is provided with a fixing member. Double-sided adhesive tape 5 is used as the fixing member, and the ground electrode is attached to the panel surface around the ground point of the car body. A ground wiring member 7 connected to an electrostatic shock preventer (not shown) is connected to the connection terminal 6 of the ground electrode substrate 2 by soldering or the like.

The ground electrode substrate 2 is made of a resin of good conductor in addition to a conductive metal such as brass plated with tin. The deformable electrode 3 is made of steel wool, stainless wool, conductive urethane foam, conductive rubber, etc., and its thickness is deformed by being pressed at the ground point when the ground electrode substrate is fixed to the panel surface. However, it is selected so that reliable contact can be obtained.

In this embodiment, the deformable electrode is fixed to the ground electrode substrate 2 with a conductive adhesive, but the central portion surrounded by the double-sided adhesive tape is used without using the conductive adhesive. It is also possible to position the deformable electrode and attach the ground electrode to the panel with the electrode being in direct contact with the ground electrode substrate surface.

Next, a method of using the ground electrode will be described. The earth electrode 1 can be attached to any place where body earth can be obtained. Here, as the earth point, the one using the screw for tightening the door lock shown in FIG. 4 will be explained. The door lock tightened by the screw 11 is provided on the automobile door 10, and the screw head of this door lock is provided. Then, the electrode 3 of the ground electrode is pressed against as shown in FIG. 3, and the adhesive tape 5 is adhered and attached to the surface of the door panel 12.

[0009]

[Effect of device]

 As described above, according to the present invention, by combining the ground electrode substrate and the deformable electrode, they can be attached without loosening or packing screws or bolts. Since it is pressed against screws and bolts and directly contacts in the deformed state, it is possible to reliably ground.
