Description

Wearable smart device and connector conversion adapter

The present invention relates to an electrical connection method between a clothes-type input / output interface and the detachable device in a wearable smart device including at least a clothes-type input / output interface and a detachable device.
Furthermore, the present invention relates to a wearable smart device including at least a garment-type input / output interface and a detachable device, and when the garment-type input / output interface and the detachable device have different connection terminal shapes and / or terminal intervals, both are electrically and mechanically joined. It is related with the connector conversion adapter used in order to make it.

In recent years, techniques for measuring sensory devices in clothing and measuring biological signals and movements of humans, animals, etc. have been rapidly developed and are widely used in fields such as sports, medical, and health monitoring. . These wearable electronic devices are called wearable smart devices.

A typical configuration of a clothes-type wearable smart device is a combination of a clothes-type input / output interface having electrodes, sensor devices, wiring, connectors, and the like, and a detachable detachable device. Here, the detachable device is an electronic device that performs detection, measurement, calculation, storage, communication to the outside, and the like of minute signals obtained from electrodes and sensor devices.
Wearable smart devices are worn by the body and are contaminated with biologically derived substances and external dust, so it is necessary to withstand washing in the same way as normal clothes. However, general electronic devices composed of conventional electronic circuits may have some waterproof functions, but they have high waterproof performance equivalent to clothing, detergent and washing durability that can withstand the drying process. Not prepared. As a result, a realistic and eclectic manner of removing the electronic device part at the time of washing has been generalized. The same concept is applied not only to wearable smart devices but also to products that combine fabric and electrical elements such as carpet-type seat heaters. (Patent Documents 1 and 2)

JP 2003-77566 A Japanese Patent Laying-Open No. 2015-135723

Although attempts have been made for a long time to embed wiring elements in clothes and to provide electronic and electrical functions, many of them have been made by connecting existing connectors to the wiring prepared in the clothes. For example, an audio pin jack or a USB terminal. Such a connector is easy to come off during use and is relatively large in size, and therefore, the thickness of the connector is likely to cause troubles such as the clothes partially rubbing against the skin or being easily caught on the outside.

The snap hook connector as described in Patent Document 1 and Patent Document 2 is a technique suitable for the process of manufacturing clothing, and can be used well when attaching and detaching flexible fabrics. It is. However, when applied to a detachable device intended by the present invention, since a plurality of connecting portions are arranged on a rigid housing surface on the device side, a deformation function is required only on the clothing side when attaching and detaching. There is a problem that an excessive force is applied to the attachment portion of the garment and the electrical connection on the clothes-type input / output interface side is easily damaged.

Furthermore, in situations where the subject moves violently, such as when measuring biological information during exercise, excessive force is continuously applied to the connector part on the clothing side due to the inertia of the mass of the detachable device, which can easily cause damage. There may be a problem that the detachable device falls off when the electrical contact becomes dense and noise, or when the movement is particularly intense.

In recent years, detachable devices having various functions have been developed. However, there is no standardization of the connection part with the clothes-type input / output interface, and compatibility is not ensured, so the clothes-type input / output interface side must be replaced every time the detachable device is replaced. There is a bug.

In addition, if the connection terminal provided on the clothes-type input / output interface is exposed, the connection terminal may be contaminated by environmental dust, sebum, etc., causing troubles that may impede the electrical connection. When a portion having a potential is touched, there is a risk that an electric shock may be applied to the adherend through the wiring laid on the interface.

As a result of intensive studies to achieve the above-described object, the present inventors have caused the detachable device in use to fall off and the connection part to be incomplete by keeping the fitting connector attachment / detachment strength within a predetermined range. We have found a wearable smart device that can be used for a long period of time without generating noise and applying an excessive load to the clothes-type input / output interface when removing the detachable device.
Furthermore, the present inventors have arrived at an invention in which different detachable devices can be mounted on the same clothing type input / output interface by improving the clothing side interface side.
Furthermore, the present inventors have improved the clothing side interface side, thereby reducing the contamination of the connection terminals and improving the safety, and further keeping the attachment / detachment strength of the fitting type connector within a predetermined range. Can be used for a long time without detaching the detachable device or generating noise due to imperfect connection, and without applying excessive load to the garment-type I / O interface when removing the detachable device I came to find wearable smart devices.
Furthermore, the present inventors use a connector conversion adapter that is used to electrically and mechanically connect the garment-type input / output interface and the detachable device when the connection terminal shape and / or terminal interval are different, thereby providing a terminal. Even when the shape and / or the terminal interval are different, the present invention has led to an invention that allows a detachable device to be mounted on the same clothes-type input / output interface.

From the viewpoint of easy attachment / detachment, it is preferable that the male / female detachment force of the fitting body is small. On the other hand, in order to hold the detachable device so as not to be stably detached with respect to vibrations and accelerations associated with movement, a desorption force of a certain level or more according to the mass of the detachable device is required.
(Hereinafter, an example in which a male mold is arranged on the clothes side and a female mold is arranged on the detachable device side will be described. However, even if the male and female are replaced, the same composition is obtained and is within the scope of the present invention.)
However, if priority is given to the stable maintenance of the detachable device and the detachment force is set too high, the connection part between the male mold of the fitting body attached to the garment side and the electrical wiring material placed on the garment, especially at the time of removal. Alternatively, an excessive load is applied to the connection portion between the male mold and the cloth fabric itself constituting the clothes, and both electrical and mechanical damages are likely to occur.
In particular, in the case where the structure on the detachable device side is rigid and the female mold of the fitting body is installed on the same plane, the detachment operation is performed by pulling the clothes side, and the detachment force is further fitted.

In this case, a pair or more of electrical contacts are required for connection between the clothing side interface and the detachable device. As such an electrical connection point, a fitting body such as a snap hook can be used.
Such fittings usually have exposed electrical contacts. In the present invention, the electrical contact portion is accommodated in a pocket having a predetermined electrical insulation, thereby reducing contamination of the electrical connection point due to dust, sebum, etc., and the electrical terminal is accommodated in the pocket. This has the effect of reducing the risk of accidental electrical shock.

According to the present invention, by using the fabric as the base material of the connector conversion adapter, the terminal shape and / or the terminal interval can be converted and adapted, and at the same time, the flexibility of the base material allows the clothes-type input / output interface and the detachable device to be adapted. The attachment / detachment is facilitated, and in particular, it is easy to remove carefully when removing. Therefore, it is possible to extend the durable life of the contact portion of the clothes-type input / output interface.
Further, in the present invention, by using the fabric for the adapter base material, when the wearable smart device adherent exercises violently, an effect of absorbing and reducing the vibration load by the adapter can be obtained. As a result, it is possible to obtain both effects of reducing the risk of detachable device dropout and reducing damage to the electrical connection on the clothing input / output interface side.
