By the way, the outer surface of a sports ball is deformed when an external force such as an impact is applied to the outer surface. At this time, the electronic component provided inside the elastic member of Patent Document 1 receives an external force due to a change in the internal pressure inside the elastic member in addition to the external force due to the deformation of the outer surface of the elastic member.
For this reason, the light emitting element provided on the outer surface of the elastic member and the electronic component stored inside the elastic member differ in the moving distance and the moving direction due to the external force, and the distance between the light emitting element and the electronic component suddenly increases. It may change and the cable such as the wiring connecting the light emitting element and the electronic component may be broken.

In view of the above problems, the present invention prevents a cable connected to an electronic component provided inside a sports ball formed in a hollow shape from being broken by an external force applied to the sports ball.

The sports ball 1D is formed in a hollow shape, and includes a main body 10, an electronic component holding portion 20B, one terminal holding portion 30, one displacement absorbing portion 90, and one lid portion 50.

In the displacement absorbing portion 90, an extensible material (for example, rubber or the like) is formed in a film shape, and at least a part of the edge edge is joined (for example, crimped or bonded) to the inner surface of the main body 10 to form an inner surface of the main body 10. The electronic component holding portion 20B is attached at a position away from the main body 10 on the surface erected from the main body 10.
Specifically, the displacement absorbing portion 90 is formed in a piece shape that stands upright from the inner surface of the main body 10 toward the center of the main body 10, and holds the electronic component on the surface of the piece at a position away from the main body 10. The electronic component 21 is attached by the portion 20B.

As a result, an external force is applied to the main body 10, and even if the position where the external force is applied is near the position where the electronic component 21 is attached, the electronic component 21 is attached to a position away from the main body 10. Therefore, it is possible to prevent the electronic component 21 from being damaged.

According to the third to fifth embodiments, the film of the stretchable material can urge the electronic component holding portion 20B holding the electronic component 21 to return to the initial relative position. Further, by forming the displacement absorbing portions 70, 80 and 90 into a film shape, the main body 10 and the electronic component holding portion 20B can be integrated without impairing the elasticity of the sports balls 1B, 1C and 1D.

Further, according to the third to fifth embodiments, the displacement absorbing unit 70, the displacement absorbing unit 80, and the displacement absorbing unit 90 hold the electronic component 21 on the surface, so that when an external force is applied to the main body 10. , External force is absorbed by the displacement absorbing unit 70, the displacement absorbing unit 80 or the displacement absorbing unit 90, which is arranged inside the main body 10 and holds the electronic component 21 on the surface via the electronic component holding unit 20B, to the electronic component 21. Can cushion the impact of.
Therefore, it is possible to prevent damage to electronic components (for example, a substrate or a component such as a sensor mounted on the substrate) while maintaining the mechanical characteristics of a conventional sports ball.

Further, according to the first to fifth embodiments, when an external force is applied to the main body 10, the terminal holding portion 30 attached to the main body 10 and the electronic component holding portion 20 arranged inside the main body 10 Or 20B moves in different directions, and the relative position of the electronic component holding portion 20 or 20B with respect to the terminal holding portion 30 changes. In this case, the displacement absorbing units 40, 40A, 70, 80 or 90 urge the electronic component holding unit 20 or 20B to return to the initial relative position P of the electronic component holding unit 20 or 20B with respect to the terminal holding unit 30. ..
Therefore, when an external force is applied to the main body 10, the pulling force applied to the cable 32 connected to the terminal 31 of the terminal holding portion 30 and the electronic component 21 held by the electronic component holding portion 20 or 20B is reduced. , It is possible to prevent the cable 32 from being broken.
Therefore, it prevents the cable connected to the electronic component provided inside the sports ball formed in a hollow shape from being broken by the external force applied to the sports ball, and all related to the cable or the electronic component. Damage to electrical contacts can be prevented.

Further, according to the first to fifth embodiments, the cable 32 has a terminal 31 in a state where an external force is applied to the main body 10 and the relative position of the electronic component holding portion 20 with respect to the terminal holding portion 30 is changed to the maximum. Since it is formed with a length longer than the distance from the electronic component 21 to the electronic component 21, a large external force is applied to the main body 10 so as to maximize the distance from the terminal 31 to the electronic component 21, and the terminal of the electronic component holding portion 20 is formed. Even if the relative position with respect to the holding portion 30 changes to the maximum, the wire does not break.
As a result, it is possible to more reliably prevent the cable connected to the electronic component provided inside the sports ball formed in a hollow shape from being broken by the external force applied to the sports ball.

Further, according to the first to fifth embodiments, the lid portion 50 covers the terminal 31, and the engaging portion 34 protruding from the peripheral surface of the terminal holding portion main body 33 in which the terminal 31 is embedded is the lid portion 50. Since it is closely engaged with the lid groove 50b formed on the inner surface 50a of the above, it is possible to prevent water and dust from entering the terminal 31.

It will be apparent to those skilled in the art that various changes or improvements can be made to the above embodiments. Further, it is clear from the description of the scope of claims that the form to which such a modification or improvement is added may be included in the technical scope of the present invention.

As an application example of the above embodiment, the electronic component 21 may wirelessly (wirelessly communicate or non-contact charge) transmit / receive information, charge a battery, or the like with an external device. In this case, in the sports ball, the terminal holding portion 30, the cable 32, and the lid portion 50 can be omitted.
