Description

  The present invention relates to a protective cover for protecting a tip portion of an electric cable used by being connected to a terminal insertion portion provided in a portable information terminal device such as a smartphone.

  In recent years, with the dramatic increase in smartphones, usage time has increased particularly in young people, and the consumption of rechargeable batteries built into smartphones has increased. The situation requires charging.

  For example, when charging a smartphone, charging is performed by inserting a connector at the tip of the electric cable into a terminal insertion portion of the smartphone via an electric cable from a personal computer (PC) or a charger.

  However, there is a problem that the cord is frequently bent at the joint portion between the connector and the cord at the distal end portion of the electric cable while charging is frequently repeated, resulting in fatigue disconnection.

  In addition, since the knob portion of the connector at the tip portion of the electric cable is small, it is difficult to grasp the small knob portion, especially for users with large fingers, and the connector at the tip portion of the electric cable is inserted into the terminal insertion portion of the smartphone There was also a problem of inconvenience.

  Therefore, as a means for solving the above problems, a protective cover according to the present invention is a protective cover that protects a tip portion of an electric cable that can be connected to a terminal insertion portion provided in a portable information terminal device. A cover main body made of a synthetic resin having elasticity, and a hole penetrating from the front end to the base end of the cover main body, and on the back side of the hole, the back portion of the cover main body A thin slit is formed from the distal end to the proximal end, so that the back portion of the cover body is separated into right and left, the hole is formed in a large diameter from the distal end to the central portion, and from the central portion to the It is characterized in that it is formed with a small diameter toward the base end and a stepped shape is formed in the central portion.

  The tip portion of the electrical cable refers to a connector at the tip of the electrical cable, a joint portion between the connector and the cord, and a part of the joined cord.

  Since the cover main body is formed by resin molding with a synthetic resin having elasticity, in the stage of using the present invention, the cut is spread by hand, and the cord of the electric cable is inserted into the hole of the cover main body. Can be inserted from the back side. When the hand is released in the inserted state, the cut line returns to the original closed state, so that the cord can be sandwiched between the cover bodies by the elasticity.

  With the cord sandwiched, when the cord is pulled in the base end direction and the connector formed wider than the cord of the electric cable is pulled into the hole, the base of the connector The position of the connector in the hole is determined by the contact portion between the connector, which is an end, and the cord coming into contact with the stepped shape and stopping.

  By determining the position of the connector, the terminal of the connector to be inserted into the terminal insertion portion can be protruded to the outside of the tip side of the hole. Furthermore, since the cord is drawn out to the base end side of the hole, the protective cover can surely cover and protect the joining portion of the connector of the electric cable and the cord.

  In this case, the large diameter constituting the hole is preferably an oval or a rectangle conforming to the cross-sectional shape of the connector so that the connector can be inserted and fitted. Moreover, it is preferable that the small diameter is also circular according to the cross-sectional shape of the cord.

  Since the hole is formed in a shape that matches the cross-sectional shape of the connector and the cord as in the configuration of the hole, the cover body can be made thin, so that the cover body can be downsized. It is possible to form the protective cover that is light and easy to grasp.

  When using the protective cover, with the protective cover attached to the tip of the electric cable, the user grasps the protective cover and inserts it into a terminal insertion portion provided in the portable information terminal device. The terminal of the connector protruding from the cover body can be easily inserted. Therefore, it is possible to prevent bending of the joint portion between the connector and the cord when the electric cable is inserted.

  The outer shape of the cover main body may be formed in a shape imitating a character. Variations other than characters may be other than dogs, cats, rabbits, or animals, and their design can create an affinity for the protective cover.

  In addition, when the outer shape of the cover main body has a shape and color scheme imitating a character, it is preferable to express a character representing a speech generated by the character with a cloud-shaped illustration or the like.

  According to the protective cover of the present invention, since the hole of the cover body is formed in a stepped shape, when attaching the distal end portion of the electric cable, the connector of the electric cable abuts on the stepped shape and stops. The position of the connector inside is determined, and the joint portion between the connector and the cord can be reliably protected.

  Further, according to the protective cover of the present invention, since the end portion of the electric cable is covered and protected, the cord is not bent at the joint portion between the connector and the cord, so that the fatigue breakage of the cord at that portion is eliminated. Further, since the cover body is elastic, the fatigue disconnection is greatly improved even when the cord drawn from the base end side of the cover body is bent.

  In addition, according to the protective cover of the present invention, when charging the smartphone, instead of grasping the small knob portion of the connector at the tip of the electric cable, the user can grasp the protective cover attached to the electric cable to grasp the smartphone terminal. Since the connector terminal at the distal end portion of the electric cable can be inserted into the insertion portion, it is easy for a user who has a large finger to grasp the electric cable, and the usability is improved.

  Furthermore, according to the protective cover of the present invention, since the outer shape of the protective cover is similar to that of a character, it is possible to provide a protective cover that allows the user to feel close.
