Description

The present invention electrically and mechanically joins a wearable smart device including at least a garment-type input / output interface and a detachable device when the connection terminal shapes and / or terminal spacings of the garment-type input / output interface and the detachable device are different. Regarding the connector conversion adapter used for the purpose.

In recent years, technology for measuring biological signals and movements of humans and animals by incorporating sensor devices into clothing has been rapidly advancing, and has come to be widely used in fields such as sports, medical care, and health monitoring. .. These wearable electronic devices are called wearable smart devices.

A typical configuration of a garment-type wearable smart device is a combination of a garment-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 detects, measures, calculates, stores, and communicates with the outside a minute signal obtained from an electrode or a sensor device.
Due to the nature of wearable smart devices that are worn on the body, they are contaminated by substances derived from living organisms and dust from the outside world, so they need to withstand washing like ordinary clothes. However, although a general electronic device composed of a conventional electronic circuit has some waterproof function, it has the same high waterproof performance as clothing, detergent, and washing durability that can withstand the drying process. Not prepared. As a result, a realistic and eclectic style of removing the electronic device portion during washing has become common. The same idea is applied not only to wearable smart devices but also to products that combine fabrics and electrical elements such as carpet-type seat heaters. (Patent Documents 1 and 2)

Attempts have been made for a long time to embed wiring elements in clothes to give them electronic and electrical functions, but most of them were made by connecting existing connectors to the wiring placed in clothes. For example, a pin jack for audio or a USB terminal. Since such a connector is easy to come off during use and is relatively large in size, it is easy for clothes to partially rub against the skin or get caught in the outside due to the thickness of the connector.

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

Furthermore, in a situation where the subject moves violently, such as when measuring biological information during exercise, the inertia of the mass of the detachable device causes excessive force to be continuously applied to the connector on the clothing side, which can easily cause damage to the connector. Problems such as the detachable device falling off may occur when the electrical contact becomes coarse and dense and becomes noise, or when the movement is particularly vigorous.

Furthermore, in recent years, detachable devices having various functions have been developed. However, since the connection part with the garment type input / output interface has not been standardized and compatibility is not ensured, the garment type input / output interface side must be replaced every time the detachable device is replaced. There is a bug.

As a result of diligent studies to achieve the above object, the present inventors have used it to electrically and mechanically join the clothes-type input / output interface and the detachable device when the connection terminal shapes and / or terminal spacings are different. By using the connector conversion adapter, the detachable device can be mounted on the same clothing type input / output interface even when the terminal shape and / or the terminal spacing are different. Furthermore, by keeping the attachment / detachment strength of the mating connector within a predetermined range, it is possible to eliminate the detachment of the detachable device in use and the generation of noise due to the imperfections of the connection part, and it is excessive when the detachable device is removed. We have found a wearable smart device that can be used for a long period of time without imposing a load on the clothing type input / output interface side.

That is, the present invention has the following configuration.

The present invention further preferably includes the following configurations.

A method for measuring biological information, which is characterized by measuring.

The present invention is applied to a wearable smart device having a clothing type input / output interface and a detachable device as at least a component, and has a detachable device having two or more electrical connection terminals and two or more electrical connection terminals. In the combination of garment type I / O interfaces, the electrical connection is a combination of male and female fittings, and the electrical connection terminal spacing between the detachable device and the garment type I / O interface and / or the male of the fitting part of the electrical connection terminal. This is a connector conversion adapter used when the females do not match.
According to the present invention, by using a cloth as the base material of the connector conversion adapter, the terminal shape and / or the terminal spacing 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. Since it is easy to attach and detach, and in particular, it is easy to carefully remove it at the time of removal, it is possible to extend the durable life of the contact portion of the garment type input / output interface.
Further, in the present invention, by using the cloth as the base material of the adapter, it is possible to obtain the effect of absorbing and mitigating the vibration load by the adapter when the wearable person of the wearable smart device moves violently. As a result, both the effect of reducing the risk of the detachable device falling off and the effect of reducing the damage to the electrical connection portion on the clothing type input / output interface side can be obtained.

The fitting body in the present invention is a pair of male / female fitting bodies in which at least a part of the contact surface is a conductive material. Such a fitting functions as a so-called connector and has both electrical and mechanical connections. From the viewpoint of ease of attachment / detachment, it is preferable that the desorption force of the male / female type of the fitting body is small. On the other hand, in order to hold the detachable device so as not to be stably detached from vibration or acceleration accompanying motion, a detachable force of a certain level or more corresponding to the mass of the detachable device is required.
(Hereinafter, an example in which the male type is arranged on the clothing side and the female type is arranged on the detachable device side will be described, but the same composition will be obtained even if the male and female are exchanged, which is within the scope of the present invention.)
However, if the detachable force is set too high because the stability of the detachable device is prioritized, the connection between the male shape of the fitting attached to the garment and the electrical wiring material placed on the garment, especially when removing the device. Alternatively, an excessive load is applied to the connection between the male mold and the cloth itself that constitutes the garment, and both electrical and mechanical damage is 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. Special care for breakage is required as it makes it easier to concentrate on part of the coalescence.
Within the range of the detachable force of the fitting body in the present invention, both the holding of the detachable device and the prevention of damage of the detachable director are compatible. Further, in the present invention, a particularly high effect can be obtained when the contact area of the fitting body with the garment cloth or the wiring on the Igu district side satisfies a predetermined condition.
Furthermore, a high effect can be obtained when the mass of the detachable device satisfies a predetermined condition.
