Description

AC wire drop prevention

The present invention relates to an AC cord fall-off preventing device for preventing an AC cord plug inserted into an AC outlet such as a communication device or a personal computer from being accidentally dropped from an AC outlet.

Most of the connectors used in communication devices or personal computers are equipped with a connector anti-dropout device to prevent the cable inserted into the connector from being accidentally dropped during use, and the connector itself is formed in a group with the fitting object. However, since some of the connectors are not equipped with the anti-dropout device as described above, they are easily peeled off. Among such connectors, there is a combination of an AC outlet and an AC line for use in the input unit of the power supply unit.

Originally, the AC cable, which is a cable inserted into an AC outlet, must be inserted into the AC outlet to prevent it from falling off easily. However, in reality, there is a disadvantage that the AC cable is easily detached from the AC outlet because there is no fall-off prevention mechanism.

Screw-on AC power sockets are fitted with AC power sockets with fixing screws. An AC wire drop prevention device of the type in which the AC socket itself is attached to the apparatus body while being fixed to the device body or attached to the screw body has been proposed (for example, refer to Patent Document 1).

The non-screw type (inserted type) AC power socket has no fixing wire that is inevitable in order to fix the AC wire drop prevention tool, and the above-mentioned AC wire fall prevention tool cannot be used. Therefore, the AC wire with a relatively inserted state is selected. In order to prevent the disconnection of the AC wire, there is a problem of certainty, and it is a major problem in infrastructure devices that require reliability.

Patent Document 1: Japanese Patent Laid-Open No. 4-162968

Regarding the non-screw fixed AC outlet, it is not only impossible to jointly lock the AC wire drop prevention screw, but also one of the purposes of using a non-screw fixed AC outlet, that is, the construction area allowed by the configuration of the AC outlet is affected by Limited. When a non-screw type or plug-in type AC outlet is used, there is a lot of space in the vicinity thereof. Therefore, it is not possible to prepare the screw fixing portion for fixing the AC wire drop prevention tool, and it is difficult to achieve an effective countermeasure against the disconnection of the AC line. Therefore, when the limitation of the construction area is a priority, there are still many devices that are manufactured and used without the possibility of the AC wire drop prevention device without the possibility of the AC wire drop-off accident.

The present invention has been made in view of the above problems, and an object thereof is to provide an AC wire fall-off preventing device capable of:

(1) A structure in which the AC wire drop prevention device is fixed to the AC outlet without a fixing screw, thereby preventing the AC wire from falling off even when inserted into the fixed AC outlet, and

(2) Up to now, since there is still no AC wire drop preventing device that can be used for inserting a fixed AC outlet, the present invention has not been decomposed or removed in many devices that have been manufactured and operated without the AC wire drop prevention device. The AC outlet can be added.

In order to achieve the above object, the AC electric wire fall-off preventing device of the present invention is inserted into an AC electric wire of a socket provided in a recess of the main body to prevent it from coming off the socket, and is characterized in that:

(1) an installation tool attached to a peripheral portion of the opening of the recess of the body;

(2) A fixture for fixing the mounting tool and the AC wire.

Here, the mounting tool can also be attached

(3) consisting of four rectangular plate-like members which are protruded from the peripheral edge portion of the opening and whose adjacent sides are connected to each other;

(4) A hole for locking the fixture is formed in any of the plate members.

(5) The mounting tool is formed with a pair of insertion pieces which are inserted into the gap between the concave portion of the body surface and the peripheral member at the peripheral edge portion of the opening and fixed.

Moreover, the fixture can also have:

(6) two locking rods, one end of the longitudinal direction of which is locked to the mounting member, and the other end of the longitudinal direction thereof is formed with a thread;

(7) pressing the metal fitting, and inserting an insertion hole inserted into the other end of each of the two locking bars of the two locking bars at both ends in the longitudinal direction thereof for pressing the AC electric wire to the socket;

(8) a knob-shaped nut that is screwed into the thread to press the pressing metal member toward the socket

Furthermore, the locking bar can also be

(9) penetrating through a hole formed in a plate-like member opposed to the mounting member,

(10) An anti-shedding tool is attached to the through end.

Furthermore, the fixture can also have:

(11) a bundle of resin; and

(12) The wire fixing fixture is formed with a central portion suspended in a central portion of the longitudinal direction of the plug shoulder portion and a bent portion through which both ends of the binding band pass through the longitudinal direction thereof;

(13) The mounting member is formed with an angular hole through which the binding band passes.

Further, the socket according to the present invention refers to a connector for an AC power input portion, and generally refers to an iron plate hole (recess) attached to a main body device (for example, a power supply unit or the like). The AC outlet port, which is a connector for the AC power output unit, is also effective for the present invention.

In the AC electric wire fall-off preventing device of the present invention, the mounting tool is attached to the peripheral edge portion of the opening of the main body recess by the insertion side of the mounting device inserted between the main body portion and the AC electric socket, and the mounting tool and the AC electric wire are fixed by the fixing device. . Therefore, the AC electric wire can be surely fixed to the socket even if the socket is fixed to the electronic device body without using a fixing screw. In this case, it is not necessary to add a new mounting area to the socket, that is, it can be additionally installed in the installed device. The mounting device can be detachably attached to the socket without the AC wire being attached to the socket. However, it is safe to disassemble the AC cable in the state of being inserted into the socket. Moreover, the manufacturability of the fixture can be improved by making the fixture into a thin plate (made of metal or resin).

According to the present invention, an AC electric wire fall-off preventing device which is used when a plug to which an AC electric wire is connected is inserted into a socket in which a recess of a main body of an electronic device is embedded and fixed.
