[Industrial application field]

The present invention provides a U-shaped protective plate body disposed perpendicularly to a connector mounting/dismounting direction and having an opening for mounting/dismounting a connector corresponding to a fixed connector fixedly mounted on an electronic device. The present invention relates to a connector fixing device for an electronic device, in which a fixing member is attached to an attached connector so as to cover it, and an inner recessed portion of the fixing member is used to prevent the connector from falling off.

[Conventional technology]

On the external connection surface of the electronic device, a protective cover having only an opening for connecting and disconnecting the connector is disposed perpendicular to the direction of connecting and disconnecting the connector in order to protect the fixed connector and the like.

In order to prevent the connector attached to the fixed side connector from being unintentionally removed, it is common to screw or otherwise secure both sides of the connector in the longitudinal direction. In addition, if the cable is pulled out parallel to the longitudinal force direction of the connector in order to reduce the protruding dimension of the external cable from the connector, it is not possible to fix that part with screws, so it is necessary to The connector is prevented from coming off by attaching a metal fitting and tying the base of the cable to this metal fitting with a nylon band or the like.

[Problem to be solved by the invention]

However, the above-mentioned conventional measures for preventing connector disconnection by fixing with screws or tying with a band have poor workability, and especially in the latter case, additional troublesome work such as attaching metal fittings and tying the band is required.

In view of these points, the present invention can safely and reliably prevent the attached connector from coming off, regardless of the direction in which the cable is pulled out from the connector, and can do this simply, conveniently, and quickly. The object of the present invention is to provide a fixing device for a connector.

[Means to solve the problem]

In order to solve the above problems, according to the present invention, a protective connector is provided perpendicularly to the mounting/dismounting direction of the connector and has an opening for mounting/dismounting a connector corresponding to a fixed side connector fixedly mounted on an electronic device. In a connector fixing device for an electronic device, a U-shaped fixing member is attached to a plate body so as to cover an attached connector, and an inner recessed portion of the U-shaped fixing member is used to prevent the connector from falling off. Each outer surface of the covered side has a groove extending perpendicularly to the direction of connector attachment/detachment, and the opening of the plate is wider than the external dimension between both outer surfaces of the covered side of the fixing member. a wide opening consisting of parallel edges, and a narrow opening consisting of a pair of parallel edges continuous to this wide opening and capable of fitting into and engaging with both grooves on the covered side of the fixing member. and placing the fixing member through the wide opening with respect to the attached connector, and translating the fixing member along the opening such that the groove thereof engages the parallel edge of the narrow opening. A feature of the structure is that the connector is fixed by pressing the button.

[For production]

When the fixing member is placed over the attached connector through the wide opening of the plate body and the fixing member is translated along the opening, the groove of the fixing member engages with the parallel edge of the narrow opening. do. As a result, the connector is prevented from falling off by the inner recessed portion of the fixing member, that is, the connector is securely fixed.

〔Example〕

The present embodiment will be described below with reference to the drawings.

Fig. 1 is a perspective view of an embodiment of the connector fixing device for an electronic device according to the present invention, Fig. 2 is a side sectional view of the main part of the embodiment of Fig. 1, and Fig. 3 is a main part of the device. It is a perspective view of a fixing member.

Referring to FIG. 1, FIG. 1(a) shows the electronic device 51 (second
A protective cover 5 is disposed perpendicularly to the connector mounting/dismounting direction and has a rectangular opening 54 for mounting/dismounting a connector 53 corresponding to the fixed connector 52 (FIG. 2) fixedly fixed to the connector 52 (FIG. 2).
5, the state before the U-shaped fixing member 1 is attached to the attached connector 53 is shown, and FIG.
(Similar figure) shows a state in which the fixing member 1 is engaged with the protective cover 55 at its inner recessed portion so as to prevent the connector from falling off.

The fixing member 1, as best understood from FIG. A groove 2a is formed on the side surface and extends perpendicularly to the connector attachment/detachment direction. Note that this groove 2a has a protrusion 2 at its center.
It is separated by b.

On the other hand, the square opening 54 of the protective cover 55 allows the fixing member 1
A wide opening 4 consisting of a pair of parallel edges 4a that is wider than the external dimension A (FIG. 2) of the fastening part 2 on the covered side of It has a narrow opening 5 consisting of a pair of parallel edges 5a with narrow dimensions that can fit into both grooves 2a.

In addition, in FIG. 1, because of the presence of the connector 53, the other (inner side) of the pair of parallel edges 4a, 5a is limited and cannot be seen.

As described above, the opening 54 of the fixing member 1 and the protective cover 55
As shown in the arrow in FIG.
Insert it into the wide opening to the position facing the connector 53, and then insert it into the wide opening 53 while maintaining that position.
4 so that the parallel edge 5a of the narrow opening 5 fits into the groove 2a. As a result, the fixing member 1 is firmly attached to the protective cover 55,
Therefore, the connector 53 is effectively prevented from coming off by the inner recessed portion of the fixing member 1. Moreover, its installation (
(attachment) is extremely easy. Further, unlike conventional bands, etc., it can be reused any number of times, and the state of use (fixed) can be determined at a glance, which is convenient. Furthermore, there are no particular restrictions on the direction in which the cable is drawn out from the connector, and other excellent effects can be obtained.

It should be noted that a predetermined portion of the narrow opening 5 of the protective cover 55 is provided with a wide groove 6 that is wider than the opening 5. Therefore, when the fixing member 1 covered as described above is translated along the opening 54, the protrusions 2b on both sides of the engaging portion 2 of the fixing member 1 snap into the wide groove 6. As a result, the fixing member 1 can be safely and reliably secured to its fixed position with respect to the protective cover 55, thereby completely eliminating the possibility of the fixing member 1 falling off due to vibration or the like. Needless to say, fixing member 1
In order to remove it, it can be easily removed by holding both sides with fingers and deforming it inward so that the protrusion 2b comes out of the wide groove 6, and then performing almost the reverse of the above-mentioned fastening operation.

Finally, modified examples of the fixing member will be explained with reference to FIGS. 4 to 6, but explanations of parts common to the fixing member 1 will be omitted, and only specific parts will be explained in detail. The fixing member 1 has a cylindrical protrusion 11a at its innermost part that actually prevents (or presses) the connector from coming off. The protrusion 11a is surrounded by a discontinuous penetrating arcuate groove 1lb, and has a recess 11c in its upper central portion.

This protrusion 11a can be inserted, for example, with a flathead screwdriver (
(not shown) into the recess 11C and can be removed by twisting it. That is, the protrusion 11a is supported by four coupling parts 11d that integrally connect the protrusion 11a with the main body of the fixing member 11, and the coupling parts lid are strong against forces in the direction of the central axis of the protrusion 11a. The protrusion 11a is supported so as to be somewhat weak against the force in the twisting direction.

As a result, it is possible to use the fixing member 11 as it is for a predetermined type of connector, and to simply remove the protrusion 11a for a connector whose height is higher than this. Note that, although not shown, by making the protrusion 11a removable in multiple stages, extremely practical and economical fixing of the connector is possible.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to provide an extremely practical connector fixing device that can easily and quickly fix a connector and can safely and reliably prevent the connector from falling off.
