Abstract

PROBLEM TO BE SOLVED: To prevent the dropping out of a cable when a cable itself has no lock mechanism by providing a cable guide member for guiding the cable so as to bend at about a right angle or more to the direction of separating a connector. SOLUTION: A clamp member 2 as a cable guide member for guiding a cable 3 so as to bend at about a right angle or more to the direction of separating a connector 10 is fitted to the mounting plate 1 of a frame. The cable 3 is pushed and hooked in the clamp member 2. When the cable 3 is removed, the lock of the clamp part 2 is released. According to this, even in the cable 3 having a dropping-out preventing mechanism in the connector 10, since a divided force in the direction substantially orthogonal to the separating direction or in the inserting direction acts on the connector 10 when the cable 3 is pulled, the connector 10 is never dropped out.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector cable holding structure of an electronic device which is suitable for use in a device in which a cable having no secure locking mechanism is used in an external interface portion of the electronic device. Things.

[0002]

2. Description of the Related Art As a connector cable connected to an electronic device, there is an interface cable used for communication with the outside in addition to a power supply. This interface has recently been developed to a new standard, and its connector shapes are diverse. There are cables that have a mechanism to prevent the cable from being unplugged, such as a cable that prevents the cable from being accidentally pulled out by attaching a screw to the connector, or a cable that can only be pulled out by holding the lever. However, there is an increasing number of cables that do not have a peculiar disconnection prevention mechanism depending on the interface standard. In order to prevent the cables from coming off, there are known methods of sandwiching the cables by a case member and utilizing a step between a connector portion and a core portion of the cable.

[0003]

The interface cable is usually located on the back, side, etc. of the product, and is often difficult to see under normal conditions. When cleaning or moving electronic devices, or when pulling a cable for any reason,
The disconnection of the cable may cause loss of data, malfunction of the entire system, or the like. In order to avoid such a situation, there is a cable having the above-described lock mechanism. However, recently, an interface standard cable having no special lock mechanism is increasing.

[0004] In such a cable, a method of sandwiching the cable by a case member or a structure in which a step is provided between a connector portion and a core portion of the cable to prevent disconnection cannot be used for a plurality of cables. There are problems such as the inability to easily insert and remove the cable, and the effect being lost if the cable manufacturer changes and the dimensions of the connector section change.

[0005] Therefore, an object of the present invention is to provide a cable having no lock mechanism, without being affected by differences in the shape due to the type, number, and manufacturer of the cables.
An object of the present invention is to provide a structure for preventing a cable from coming off.

[0006]

In order to achieve the above object, a cable holding structure according to the present invention comprises a first connector provided in an electronic device, and a cable which is inserted into the first connector and provided with a cable. In the connector cable holding structure having the second connector, the cable from the second connector is substantially perpendicular to the direction in which the second connector is disconnected near the first connector. It has a cable guide member for guiding to bend more than required.

[0007] With the above structure, even if the cable is pulled, the second connector is prevented from coming off because a component force is applied to the second connector in a direction substantially perpendicular to the detaching direction or in the inserting direction.

Here, it is preferable that the cable guide member has a contact portion that comes into contact with the cable at a position closer to the first connector than at a position where the cable starts to bend.

[0009] It is also preferable that the cable guide member has an edge formed at a portion in contact with the cable.
In this case, the frictional load when the cable is pulled is increased, and the detachment of the connector is prevented.

[0010] Further, the cable guide member is provided with the first member.
It is also effective that both sides of the connector are integrally formed from a frame supporting the first connector,
For example, the number of parts of the apparatus can be reduced by also using the handle shape.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an external view of an interface unit of an electronic apparatus using one embodiment of the present invention.

In FIG. 1, a clamp component 2 as a cable guide member is fitted into a mounting plate 1 of a frame. A connector 10 as a first connector is mounted on a circuit board 11 and is screwed to the mounting plate 1 by board fixing screws 20.

The connector 3A, which is the second connector provided with the cable 3, is inserted into the connector 10 of the interface unit, and the cable 3 is hooked on the clamp component 2, thereby exerting the effect of preventing the cable 3 from coming off. At this time, the clamp component 2 can be hooked only by pushing the cable 3 in, and has a structure that is not easily detached even when the cable 3 is pulled. Is preferably removed by releasing.

Further, by having a structure in which the cable 3 can be easily attached and detached without disconnecting the connector 3A, even if another cable 3 is added or removed later, the cable 3 is connected to the already connected cable 3. You can work without impact. It is preferable to select the size and the mounting position of the clamp component 2 in consideration of the case where the maximum number of cables 3 having no lock mechanism is used.

Although the clamp part 2 rotates as it is, when it is mounted on the product body, the mounting screw 2
1, the rotatable angle is regulated, and the work of attaching and detaching the cable 3 becomes easy.

The cross-sectional shape of the clamp part 2 at the portion that comes into contact with the clamp 2 when the cable 3 is pulled is the cross-sectional shape of the portion at which the cable 3 bends and comes into contact with the clamp 2 because the corner has an edge. The friction increases, and the pull-out force applied to the connector 3A is reduced compared to the external force actually applied to the cable 3.

FIG. 2 shows a state in which the interface unit 1A is actually attached to the product main body 31.

The interface unit 1A is mounted on the product frame member 30 with mounting screws 21. At this time, since the cable 3 is not pulled to the side by the wall 32 of the product case member, the direction of the force applied to the cable 3 can be surely changed by the clamp component 2, and the function of preventing the cable 3 from coming off is stabilized.

The interface unit 1A can be attached to other products compatible with the unit. However, even in such a case, the function of preventing the cable 3 from coming off is completed within the interface unit 1A. Therefore, there is no influence of the peripheral shape which differs for each product.

FIG. 3 is an enlarged view of the handle portion 4 of the interface unit to which a clamping function is added. By using this shape, the clamp component 2 can be omitted. Further, the ease of use as a handle when attaching and detaching the interface unit is improved.

[0022]

As described above, according to the present invention, even if the cable does not have a mechanism for preventing the connector from being detached, even if the cable is pulled, the second connector does not disengage. The second connector is prevented from coming off because a component force in a direction substantially perpendicular to or in the direction of insertion acts.
In addition, the effect of preventing disconnection can be obtained regardless of the type and number of cables, and the number of cables can be easily increased or decreased.
