Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a cabinet, and more particularly to a cabinet constituting an electric device having a power cord.

[0002]

[Prior art]

 As a conventional cabinet, there is a known cabinet that has a terminal insertion hole into which a contact terminal of a plug can be inserted, and the movement of the plug during transportation or the like is restricted by inserting and fixing the contact terminal into the terminal insertion hole. Have been. Further, as another cabinet, there is known a cabinet which restricts the movement of the plug at the time of transportation or the like by attaching a plug formed with a hook as disclosed in Japanese Utility Model Laid-Open No. 61-144581. As described above, the movement of the plug during transportation or the like is restricted only when the position of the plug is not determined and the distal end of the power cord is freely movable. This is because there is a risk of being pressed against the equipment or hitting peripheral equipment.

[0003]

[Problems to be solved by the invention]

 The conventional cabinet described above has the following problems. In the former case, the metal contact terminals had to be inserted and fixed in the terminal insertion holes provided in the resin cabinet, so that the cabinet was inevitably worn. On the other hand, in the case of the latter, hooks must be formed on the plug side, and thus an increase in cost due to an increase in the number of work processes and the number of parts was a problem. The present invention has been made in view of the above problems, and an object of the present invention is to provide a cabinet that can control the movement of a plug at the time of transportation or the like without causing wear of the cabinet.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the invention according to claim 1 includes a receiving hole that is recessed in the outer wall surface and that receives a plug provided at the tip side of the power cord, and a portion near the opening edge of the receiving hole and near the opening. And a protrusion structure that restricts the movement of the plug when the reinforcing portion formed between the end of the power cord and the base of the plug is sandwiched between the inner wall surface of the housing hole. There is a configuration to have. In the invention according to claim 1 configured as described above, the plug provided on the front end side of the power cord is accommodated in the accommodation hole recessed in the outer wall surface, and the tip of the power cord and the root of the plug are accommodated. Between the inner periphery of the housing hole and the inner wall surface of the housing hole. The position of the reinforcing part is fixed by the repulsive force trying to restore in the depth direction of the hole, and the movement of the plug is restricted.

That is, since the reinforcing portion is usually formed integrally with the plug, movement of the plug is restricted when the position of the reinforcing portion is determined. Since the reinforcing portion is not as resilient as the power cord, when the reinforcing portion is sandwiched between the inner wall surface of the protruding structure and the inner wall surface of the housing hole, it is easily pressed and shrunk in the depth direction of the housing hole. Never be. In addition, since the plug is more elastic than the plug, the plug can be easily sandwiched between the inner wall surface of the protruding structure and the inner wall surface of the housing hole. Then, since the plug is held in the accommodation hole and does not protrude out of the cabinet, the plug may be pressed against the outer wall surface of the cabinet or hit against a peripheral device. Disappears. At this time, it is not necessary to directly fix the metal contact terminals provided on the plug to the resin cabinet, so that the cabinet can be prevented from being worn, and only the mold structure for molding the cabinet is changed. Thus, the shape according to claim 1 can be easily provided, so that an increase in manufacturing cost can be prevented.

According to a second aspect of the present invention, as a configuration example of the accommodation hole, in the cabinet according to the first aspect, the accommodation hole is provided on a back side of the cabinet, and the plug is disposed in a substantially horizontal direction. It is configured to be accommodated while being oriented. In the invention according to claim 2 configured as described above, the plug is received in the receiving hole provided on the rear side of the cabinet while being oriented in a substantially horizontal direction, and the reinforcing portion is provided in the projecting structure. To restrict the movement of the plug.

[0007] Normally, the power cord is led out from a lower corner on the back of the cabinet. In addition, in many cases, all structures are provided above the rear surface of the cabinet in order to exert various functions of the electric device. For example, in the case of a television set, a protruding structure is provided at the upper rear side to accommodate a cathode ray tube, and there is no space left for forming the accommodation hole. For this reason, the second aspect of the present invention is useful in that it is possible to form a receiving hole capable of receiving the plug while orienting the plug in a substantially horizontal direction by utilizing the space left below the rear surface of the cabinet. Become.

[0008] Further, as an example of a specific configuration of the accommodation hole, the invention according to claim 3 is directed to the cabinet according to any one of claims 1 or 2, wherein: A terminal insertion hole capable of inserting and positioning the contact terminal of the plug is formed. In the invention according to claim 3 configured as described above, when the plug is received in the receiving hole, the contact terminal of the plug is inserted into a terminal insertion hole formed in the inner wall surface of the receiving hole. To position.

At this time, since the movement of the plug is restricted by sandwiching the reinforcing portion between the projecting structure and the inner wall surface of the housing hole, the terminal insertion hole is not necessarily provided with the contact hole. There is no need to fix the terminals. In other words, the positioning here means that when the plug vibrates during transportation or the like and the contact terminal is about to be exposed to the outside of the accommodation hole, the contact terminal is accommodated by the terminal insertion hole. It suffices if the contact terminals can be positioned to such an extent that the contact terminals can be retained in the holes.

[0010] Further, when the plug is accommodated in the accommodation hole, an additional configuration can be provided so that the deformation of the power cord can be reduced. As an example of this additional configuration, the invention according to claim 4 is directed to the cabinet according to any one of claims 1 to 3 so that the leading end side of the power cord can be guided to the accommodation hole. A guideway that gradually increases in depth toward the accommodation hole is connected to the accommodation hole. In the invention according to claim 4 configured as described above, the plug is housed in the housing hole while the leading end side of the power cord is guided by the guide path that gradually increases in depth toward the housing hole. . For this reason, the claim 4 is useful in that deformation between the cord portion of the power cord and the reinforcing portion is reduced, and damage to the power cord can be prevented.

[0011] As a configuration example in this case, the invention according to claim 5 is the cabinet according to claim 4, wherein the guide path is provided so as to protrude from the outer wall surface in a direction crossing the guide path. It has a cord holding structure that restricts the movement of the power cord when the power cord is sandwiched between the inner wall of the taxiway. In the invention according to claim 5, the power cord is provided between a cord holding structure protruding from an outer wall surface of the cabinet in a direction crossing the taxiway and an inner wall surface of the taxiway. To restrict the movement of the power cord. Then, since the movement of the power cord can be restricted in addition to the movement of the plug by the protruding structure, the plug can be more securely held in the accommodation hole.

[0012]

[Effect of the invention]

 As described above, the present invention can provide a cabinet capable of restricting the movement of the plug at the time of transportation or the like at low cost without abrasion of the cabinet. Further, according to the invention of claim 2, the accommodation hole can be formed by effectively utilizing the space left on the back surface of the cabinet. Further, according to the invention of claim 3, exposure of the contact terminal can be prevented more reliably.

Further, according to the present invention, it is possible to prevent the power cord from being damaged. Further, according to the invention of claim 5, the plug can be more securely held in the receiving hole.

[0014]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a rear side structure of a television set according to an embodiment of the present invention.

In the television set, a cathode ray tube, a control board, and the like (not shown) are mounted in an opening provided on the back side of the front cabinet 10, and internal devices mounted on the front cabinet 10 are inserted through the opening. The rear cabinet 20 is assembled with the opening of the rear cabinet 20 facing the opening of the cabinet 10. A power supply cord 30 connected to a power supply circuit housed therein is led out from the rear side of the rear cabinet 20, and a commercial power supply is supplied to a plug 31 provided at the end of the power supply cord 30. Power input to the television set.

The power cord 30 is folded and bundled to a predetermined length when the television set is shipped from a factory or when a user carries the television set. At this time, if the position of the plug 31 is not determined and the distal end of the power cord 30 is freely movable, the plug 31 may be pressed against the outer wall surface of the rear cabinet 20 or may be located around the television set. May be hit against other devices. Conventionally, for example, as shown in FIG. 2, a pair of terminal insertion holes 40, 40 into which the contact terminals 31a, 31a of the plug 31 can be inserted are provided on the rear side wall surface of the rear cabinet 20, and as shown in FIG. The plugs 31 are fixed to the rear cabinet 20 by inserting the contact terminals 31a, 31a into the terminal insertion holes 40, 40.

As described above, when the plug 31 is fixed by inserting the contact terminals 31 a into the terminal insertion holes 40, the plug 31 is prevented from interfering with the outer wall surface of the rear cabinet 20 and peripheral devices. This is useful in that the metal contact terminals 31a, 31a contact the terminal insertion holes 40, 40 provided in the resin rear cabinet 20, so that the terminal insertion holes 40 , 40 parts were worn. Therefore, in the present embodiment, a configuration is provided in which the plug 31 can be positioned without abrasion of the terminal insertion holes 40, 40 of the rear cabinet 20.

That is, on the rear surface of the rear cabinet 20, a plug housing structure 21 capable of housing a plug 31 as shown in FIG. 1 is provided. As shown in FIG. 4, the plug housing structure 21 is provided with a housing hole 21a capable of housing the entire plug 31 including the contact terminals 31a, 31a, and a power supply at the left end of the housing hole 21a. A guide path 21b is formed to gradually increase the depth toward the accommodation hole 21a so that the distal end side of the cord 30 can be guided to the accommodation hole 21a.

Further, a protruding structure 21c that protrudes toward the opening side is formed from an opening edge of the housing hole 21a at a connection portion with the guide path 21b. As shown in FIG. 5, the depth D of the gap formed between the inner wall surface of the protruding structure 21c and the inner wall surface of the housing hole 21a is equal to the distance between the tip of the power cord 30 and the base of the plug 31. The width is set slightly smaller than the thickness of the reinforcing portion 32 formed therebetween. With this configuration, as shown in FIGS. 6 and 7, the leading end side of the power cord 30 is guided along the guide path 21b, and the reinforcing portion 32 is positioned between the inner wall surface of the protruding structure 21c and the inner wall surface of the housing hole 21a. The plug 31 is housed in the housing hole 21a while being sandwiched between them.

At this time, since the reinforcing portion 32 of the power cord 30 is made of an elastic resin, when the power cord 30 is sandwiched between the inner wall surface of the protruding structure 21c and the inner wall surface of the housing hole 21a, the reinforcing hole 32 of the housing hole 21a is formed. It is compressed in the depth direction. Then, the reinforcing portion 32 applies a repulsive force toward the inner wall surface of the protruding structure 21c and the inner wall surface of the housing hole 21a in an attempt to restore in the depth direction of the housing hole 21a. For this reason, the reinforcing portion 32 is fixed at the sandwiched position, and the movement of the plug 31 integrally formed with the reinforcing portion 32 is restricted. Here, since the reinforcing portion 32 is not as resilient as the power cord 30, when the reinforcing portion 32 is sandwiched between the inner wall surface of the protruding structure 21c and the inner wall surface of the housing hole 21a, the reinforcing portion 32 is easily directed toward the back of the housing hole 21a. Since it is not compressed and more elastic than the plug 31, it can be easily sandwiched between the inner wall surface of the protruding structure 21c and the inner wall surface of the housing hole 21a. Will be useful.

Therefore, as shown in FIG. 8, the entire plug 31 is held inside the receiving hole 21 a, and the contact terminals 31 a, 31 a do not protrude outside the rear cabinet 20, so that the contact terminals 31 a, 31 a Interference with the outer wall surface of the cabinet 20 is prevented. Since the plug housing structure 21 can be formed by simply changing the design of the mold structure used when the rear cabinet 20 is molded, the number of work steps and the number of parts increase. Cost can be prevented and the configuration can be made inexpensively. Further, since the rear cabinet 20 is provided with a protruding structure 20a for accommodating a cathode ray tube having a long depth in the front-rear direction of the television set, the space in the right and left rear portions of the rear cabinet 20 is limited. This is useful in that the plug housing structure 21 can be provided so that the plug 31 can be housed while orienting the plug 31 in a substantially horizontal direction by utilizing the space largely left below the structure.

On the right inner wall surface of the housing hole 21a shown in FIG. 6, there are provided terminal insertion holes 21d, 21d into which the contact terminals 31a, 31a can be inserted. When the plug 31 is housed in the housing hole 21a, The tips of the contact terminals 31a, 31a are inserted into the terminal insertion holes 21d, 21d. For this reason, since the contact terminals 31a and 31a can be positioned, it is useful in that the exposure of the contact terminals 31a and 31a can be more reliably prevented. The terminal insertion holes 21d, 21d need not be fixed to the contact terminals 31a, 31a unlike the conventional terminal insertion holes 40, 40 shown in FIG. 2, and therefore, are larger than the outer shape of the contact terminals 31a, 31a. Even if the contact terminals 31a are formed, the positions of the contact terminals 31a can be sufficiently determined. In this respect, unlike the conventional terminal insertion holes 40, 40 and the terminal insertion holes 21d, 21d according to the present embodiment, the terminal insertion holes 40, 40 can be formed without the rear cabinet 20 being worn.

In the present embodiment, only the protruding structure 21c is provided so that the reinforcing portion 32 of the power cord 30 can be sandwiched between the inner wall surface of the accommodating hole 21a. However, as shown in FIG. Also, a structure capable of sandwiching the power cord 30 may be added. More specifically, the cord holding structure 21e is provided to project from the outer wall surface of the rear cabinet 20 so as to cross the guide path 21b, and the reinforcing portion 32 is sandwiched between the inner wall surface of the protruding structure 21c and the inner wall surface of the accommodation hole 21a. At this time, the power cord 30 is sandwiched between the inner wall surface of the cord holding structure 21e and the inner wall surface of the guide path 21b. Then, not only the reinforcing portion 32 is fixed to the accommodation hole 21a, but also the power cord 30 can be fixed to the guide path 21b, so that the plug 31 can be more securely held in the accommodation hole 21a. .

Next, an operation when the worker houses the plug 31 in the plug housing structure 21 will be described. The operator folds the power cord 30 to a predetermined length, binds the power cord 30 with a resin ribbon containing a wire, guides the distal end of the power cord 30 along the guide path 21b, and contacts the contact terminals 31a, 31a. Into the terminal insertion holes 21d, 21d. Then, the plug 31 is accommodated between the inner wall surface of the protruding structure 21c and the inner wall surface of the accommodation hole 21a while the reinforcing portion 32 is compressed in the depth direction of the accommodation hole 21a, and the plug 31 is accommodated in the accommodation hole 21a. Therefore, by fixing the reinforcing portion 32 at the sandwiched position, the movement of the plug 31 is restricted, and the plug 31 is held so as not to protrude from the plug housing structure 21 to the outside.

As described above, the plug 31 is housed in the housing hole 21a while the reinforcing portion 32 of the power cord 30 is sandwiched between the inner wall surface of the protruding structure 21c and the inner wall surface of the housing hole 21a. Since the plug 32 is fixed at the sandwiched position to restrict the movement of the plug 31, the movement of the plug 31 at the time of transportation or the like can be regulated at low cost without abrasion of the rear cabinet 20. . By arranging the accommodation hole 21a on the opposite side of the base of the power cord 30, the power cord 30 can be fixed in a straight line without slack. Further, a flyback transformer is arranged near the base of the power cord 30, but this flyback transformer does not interfere.
