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 terminal that can be easily installed 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, an electrostatic discharge prevention device has been proposed. The grounding of this electrostatic shock protector uses stag beetle terminals, etc., and the body is grounded with screws. Tools are used for this installation. As a simple method for grounding, for example, a conductive adhesive tape can be used as shown in FIG. 3 of Japanese Utility Model Application Laid-Open No. 64-7799.

However, in the method using the conductive adhesive tape, tape peeling easily occurs when the screw head is projected from the panel surface. Further, when the screw head is sunk from the panel surface, there is a problem that the conducting part is easily peeled off. An object of the present invention is to provide a ground terminal for an electrostatic shock protector which is easy to install and enables reliable electrical connection.

[0004]

[Means for Solving the Problems]

 To achieve the above object, the grounding terminal of the present invention comprises a metal grounding plate electrically connected to an electrostatic shock protector installed in a vehicle, the metal grounding plate being a grounding point to the vehicle body. The contact piece to be brought into contact and the fixing portion for attaching to the body near the earth point are provided.

Another invention is characterized in that, in the above invention, it has the following configuration. That is, the metal ground plate is made of a conductive spring material, and its contact piece is manually bent. Further, the contact piece is formed in the plane of the metal ground plate or extending from the metal ground plate.

[0006]

[Action]

 Fix the metal ground plate with double-sided adhesive tape so that the contact piece of the metal ground plate contacts the ground point of the body, for example, the screw head of the tightening screw for the door lock. If the metal grounding plate is made of a conductive spring material, even if there is a step between the grounding point and the fixed surface of the metal grounding plate, the elasticity of the contact piece allows the metal grounding plate to contact the grounding point. Can be grounded. Especially if the earth point is lower than the fixing surface of the metal earth plate, bend the contact piece by hand before fixing the metal earth plate.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows the structure of the metal acelate. The metal ground plate 1 uses a thin metal plate having a spring property that can be easily bent by hand, and is made of, for example, a phosphor bronze plate for spring having a thickness of 0.2 to 0.3 mm. The metal ground plate 1 is provided with a plurality of cuts 2 radially from the center to the periphery to form a bendable contact piece 3. In the present example, four bendable contact pieces 3a, 3b, 3c, 3d are formed by two intersecting cuts 2.

The wiring terminal 4 of the metal ground plate 1 is connected to an electric wire 5 connected to an electrostatic shock protector main body (not shown). A double-sided adhesive tape 6 is provided on one surface of the metal ground plate 1 so as to surround the contact piece 3. Here, the double-sided adhesive tape 6 constitutes a fixing portion of the metal ground plate 1. Next, the usage of the metal ground plate will be described. The metal ground plate 1 can be attached at any place where the body ground can be obtained. Here, as the ground point, the screw for tightening the door lock shown in FIG. 3 is used. To explain, the door 10 is provided with a door lock tightened by the screw 11, while the door panel 12 is provided with the door lock. A recess 12a having a mounting hole for the screw 11 is provided at the tightening position.

As shown in FIG. 4a, when the recess 12a is shallow and the screw head 11a projects from the panel surface, the double-sided adhesive tape 6 of the metal ground plate 1 is attached to the panel surface around the screw 11. And fix it, and bring the screw head into contact with the contact piece 3 of the metal ground plate. At this time, since the screw head 11a projects from the metal ground plate 1, the plurality of contact pieces 3a, 3b, 3c, 3d are deformed as shown, and the contact state is maintained by the elastic restoring force thereof.

As shown in FIG. 4B, when the recess 12a is deep and the screw head 11a does not protrude from the panel surface, the contact pieces 3a, 3b, 3c, 3d are bent to the adhesive tape side before being adhered to the door panel. After that, the metal ground plate 1 is fixed to the panel surface around the screw 11 with the double-sided adhesive tape 6, and the contact pieces 3a, 3b, 3c, 3d of the metal ground plate are brought into contact with the screw head 11a. At this time, the contact piece 3 is lifted by the screw head 11a by fixing the metal ground plate 1 to the door panel, and the elastic restoring force keeps the contact state.

FIG. 5 shows another embodiment of the present invention. The metal ground plate 20 has one or a plurality of contact pieces 21 provided extending from one side thereof, and a wiring terminal 22 to which the electric wire 5 is connected is provided on the other side. In this example, it is composed of two contact pieces 21a and 21b. A double-sided adhesive tape 23 is attached to one side of the metal ground plate 20.

The method of using the metal ground plate 20 will be described. As shown in FIG. 6A, when the recess 12a is deep and the screw head 11a does not protrude from the panel surface, the metal ground plate 20 is contacted before being bonded to the door panel 12. After bending the pieces 21a and 21b toward the adhesive tape, the metal ground plate 20 is attached and fixed to the panel surface around the screw 11 with the double-sided adhesive tape 23, and the screw heads 11a are connected to the metal ground plates 21a and 21b. Abut. At this time, the metal ground plate 20 is fixed to the door panel 12, so that the contact piece 21 is lifted by the screw head 11a, and the contact state is maintained by the elastic restoring force.

As shown in FIG. 6b, when the recess 12a is shallow and the screw head 11a protrudes from the panel surface, the metal ground plate 12 is fixed to the panel surface around the screw 11 with the double-sided adhesive tape 23, and the screw The head is brought into contact with the contact pieces 21a and 21b of the metal ground plate. At this time, since the screw head 11a projects from the metal ground plate 20, the contact pieces 21a and 21b are deformed as shown in the figure, and the elastic restoring force maintains the contact state.

In this embodiment, the phosphor bronze plate for spring is used as the metal ground plate, but it is desirable to apply tin plating or Ni plating according to the usage environment. Further, in the present embodiment, the fixing portion of the metal ground plate is constituted by the double-sided adhesive tape, but it is also possible to fix part or all of one side of the metal ground plate as the fixing portion to the body with an adhesive. Absent.

[0015]

[Effect of device]

 As described above, according to the present invention, the metal ground plate is fixed near the grounding body to the body, and the contact piece of the metal grounding plate is brought into contact with the grounding body. Even if it projects from the fixed surface or does not project, the metal ground plate can be firmly fixed and a reliable ground can be obtained.

Also, in the case where the metal ground plate is made of a conductive spring material and the contact piece is made of a plate thickness that can be manually bent, even if there is a step between the ground point and the plate fixing surface, the metal ground plate is fixed by the fixing. By using a contact piece that is deformed or is bent in advance by hand, it is possible to ensure that the contact piece is brought into contact with the earth ponite by the elastic force of the contact piece.
