Problems solved by technology

However, when a large amount of conductive filler is uniformly dispersed, the rubber becomes hard and brittle, easily broken, and the cost becomes high
Therefore, it is difficult to achieve the conductive characteristics required to remove electromagnetic wave interference and static electricity
In this way, the third conductive silicone rubber has problems with mounting workability and conductive characteristics.

[0049] First Embodiment ( FIGS. 1 to 3 ): A connecting sheet 1 of the first embodiment includes two connector parts 2 and 3 and a resin sheet 4 as a "sheet part".

[0050] The first connector part 2 is formed of a rubber-like elastic body such as silicone rubber. The connector part 2 has a conducting part 5 and an insulating part 6 . Among them, the conduction part 5 is located at the center of the connector part 2, and is formed in a cylindrical shape in which magnetic fine conductive particles are aligned in the thickness direction of the connector part 2 (height direction along the axis). The insulating portion 6 is formed in a cylindrical shape so as to wrap around the outer periphery of the conduction portion 5 . A circular first through hole 4 a formed through the resin sheet 4 and its peripheral portion (hole edge portion) are embedded in the outer peripheral side surface of the insulating portion 6 . That is, the connector part 2 is formed so that it may penetrate th...

no. 2 approach

[0074] The second embodiment ( FIG. 4 and FIG. 5 ): the connection sheet 13 of the second embodiment is different from the connection sheet 1 of the first embodiment in the structure of the resin sheet 4 . The rest of the structure and its functions and effects are the same as those of the first embodiment.

[0075] In the resin sheet 4, notches 4d are formed between the insertion holes 4c adjacent to the first through holes 4a.

[0076] Next, an embodiment of the electronic device 9 including the connection sheet 13 of the second embodiment will be described. The electronic device 9 includes at least a connection piece 13 and a circuit board 8 inside a metal casing 10 made of, for example, a magnesium alloy. Like the connection sheet 1 , the connection sheet 13 is used to cover the circuit board 8 so as to cover the circuit elements 11 and the like arranged on the circuit board 8 . The circuit board 8 is fixed in the casing 10 with metal screws 7 . A ground connection port...

no. 3 approach

[0079] Embodiment 3 ( FIGS. 6 and 7 ): The connection sheet 14 of the third embodiment differs from the connection sheet 13 of the second embodiment in the structure of the connector part 2 and the resin sheet 4 . The rest of the structure and its functions and effects are the same as those of the second embodiment.

[0080] In the insulating part 6 of the connector part 2, the corners of both end surfaces are chamfered. That is, the connector portion 2 penetrates through the through hole 4 a of the resin sheet 4 , and is formed in a shape protruding from both surfaces of the resin sheet 4 in a truncated cone shape.

[0081] One insertion hole 4 c is formed in the resin sheet 4 , and an adhesive layer 15 is provided on the facing surface of the circuit board 8 . The adhesive layer 15 can be formed by applying an adhesive, sticking a double-sided tape, or the like.

[0082] Next, an embodiment of the electronic device 9 including the connection sheet 14 of the third embodimen...

Abstract

The invention provides a connector sheet and a portable electronic equipment which have conductive characteristics, necessary for removing electromagnetic wave noise and static electricity, in which a metal part of a cabinet and a circuit board can be grounded and connected by a simple mounting operation, and which can be adapted to size reduction of the electronic equipment. The connector sheet 1 can prevent the electromagnetic wave noise from being collected in the cabinet 10 and static electricity is charged, since it is conductively connected to the metallic cabinet 10 and a grounding connection part 12 of the circuit board 8 by a conductive part 5 of connector parts 2, 3 in which conductive particles are arranged and directed in a chain reaction. Accordingly, malfunctions due to the electromagnetic noise and static electricity can be prevented, and action reliability and action stability of the electronic equipment 9 can be realized. Moreover, since the connector parts 2, 3 and a resin sheet 4 are integrated, there is no need to position and mount the small connector parts 2, 3 by the resin sheet 4, respectively, as a single body, and mounting work can be carried out easily.

Description

technical field [0001] The present invention relates to a connection piece and a portable electronic device equipped with the connection piece. The metal part is connected to the ground of the substrate circuit built in the housing. Background technique [0002] In various electronic devices such as mobile phones and portable music players, there are more and more examples of using metal materials that have higher mechanical strength than thermoplastic hard resins and can exhibit a high-end appearance as housing materials. In particular, light metal alloys such as aluminum alloys and magnesium alloys are often used as casings of portable electronic devices because of their light weight. Among the forms in which such a metal material is used for the casing, some cases use the entire casing as a metal material, and some use a part of the casing as a metal material. [0003] When a metal material is used as the material of the housing in this way, it is necessary to ground th...
