Description

Storage Box

technical field

The present invention relates to a storage box for storing electrical components such as an external antenna provided with a connector plug at the tip of a drawn-out cable.

Background technique

Generally, a wireless communication card with a built-in wireless communication function such as PHS (Personal Handyphone System) inside a PC card is used when connecting a personal computer and a portable information terminal to a communication circuit to send and receive data.

For example, the PC card modem 100 of the wireless communication card shown in FIG. 9 is provided on the upper part of the housing part 101 by a housing part 101 with a built-in wireless communication function, a PC card part 102 protruding from the lower end of the housing part 101, and a foldable The antenna 103 is composed of; the PC card part 102 is inserted into the PC card slot 104 provided on the personal computer 105 to connect and use.

However, when transmitting and receiving signal data using such a PC card modem 100, depending on the usage situation, the radio wave condition may be bad, and good wireless communication may not be performed. Therefore, an external antenna not shown in the figure can also be connected to the housing 101 for use via a connection box.

The user therefore has to carry the PC card modem 100 along with the external antenna and connecting cables etc. At this time, in order to prevent dust from adhering, it is generally stored in a storage box or a storage bag when carrying it away.

However, a simple-structured and inexpensive sleeve antenna is often used as the above-mentioned portable external antenna. The sleeve antenna has a substantially cylindrical shape, and a connector plug 107 for connecting to a PC card modem 100 is provided at the front end of a connection box drawn from one end as shown in FIG. 10 .

As shown in Figures 10 and 11, the structure in which the substantially rectangular parallelepiped connector plug 107 set at the front end of the cable drawn out from the electrical components such as an external antenna is held in the storage box 105 is shown in Figure 10 and Figure 11, and stoppers are respectively protruded at the opposite front ends. The protrusion 101 sets a pair of parallel flexible stop pieces 103, 103 in the storage box.

Therefore, by pressing the substantially rectangular parallelepiped connector plug 107 between the pair of flexible stopper pieces 103, 103, when the connector plug 107 accidentally falls off from the storage box, it can be clamped and connected without shaking. Connector plug 107.

However, in the case of the above-mentioned pair of flexible locking pieces 103, 103, when the connector plug 107 is attached or detached, the front end is elastically deformed on the outside along with the locking protrusion 101 (in the direction of the arrow in FIG. 11 ).

Therefore, when the flexible stopper 103 is repeatedly deformed excessively when the connector plug 107 is detached, fatigue occurs and the elastic restoration force decreases. Such a decrease in the elastic restoration force of the flexible stopper 103 may result in a decrease in the clamping force on the connector plug 107 , and it may not be possible to securely hold the connector plug 107 in the storage case 105 .

Also, when the flexible stop piece 103 is integrally formed on the inner surface of the storage box 105, since the lower part of the stop protrusion 101 is recessed, there are problems that the forming mold becomes complicated and the manufacturing cost increases.

Therefore, it is an object of the present invention to solve the above-mentioned problems, and to provide a storage case capable of stably and reliably holding a connector plug at the tip of a cable while suppressing an increase in manufacturing cost.

Contents of the invention

The present invention is a storage box for accommodating electric components provided with connector plugs at the front ends of drawn out cables. A pair of plug holding walls are erected at regular intervals on an inner wall of the storage box. At least one of the two side surfaces of the connector plug is provided with a lock release knob that is pressed and operated when the lock is released, and the pair of plug holding walls clamp the lock release knob so that it is pressed. In the pressed state, the connector plug is held by the elastic restoring force of the unlocking knob.

According to the above structure, when the connector plug provided on the front end of the cable drawn out from the electrical component is stored in the storage box together with the electrical component, the pair of plug holding walls are clamped in a pressed spring state. Install it with the knob to release the lock.

Therefore, since the connector plug is clamped between the pair of plug holding walls by the elastic restoring force of the unlocking knob portion thereof, the plug holding wall itself does not need to be elastically deformed, nor does it require a sunken stopper. protruding.

In addition, the unlocking knob part has sufficient elastic travel and durability in advance, and can maintain a stable holding force even after a long time of operation.

Furthermore, it is preferable that the connection is restricted by fitting the anti-slip protrusion protruding from the pair of plug-holding walls on the anti-slip portion formed on the surface of the unlocking knob portion. The plug of the connector plug moves forward and backward.

At this time, when the connector plug is inserted between a pair of plug holding walls, the anti-slip protrusion provided on the opposite side of the plug holding wall is fitted into the anti-slip concave-convex portion provided on the connector plug unlocking knob. Therefore, the deviation of the front-back direction of the connector plug can be prevented, and it can be reliably held.

In addition, since the anti-slip concave-convex portion is used to prevent fingertips from slipping when the connector plug is pulled out from the mating connector, it is usually along the front and rear direction of the plug (connector plug Insertion and detachment direction) is a concavo-convex part with a corrugated section. Therefore, the anti-misalignment protrusion fitted on the concavo-convex portion of the corrugated section can be formed as a rib protrusion extending along a direction perpendicular to the inner wall surface of the storage box. That is, there is no possibility of denting even when integrally formed on the surface opposite to the wall for holding the plug.

In addition, it is preferable that a plurality of the anti-deviation protrusions protrude along the front-rear direction of the connector plug.

Therefore, when the connector plug is stored in the storage box, due to the influence of the cable, even if the connector plug is held one after the other, only at least one anti-slip protrusion fits into the anti-slip protrusion. In the part, a pair of plug holding walls can securely hold the connector plug while preventing deviation in the front-rear direction.

In addition, it is preferable that the restricting wall for restricting the front-rear direction of the plug for restricting the position of the connector plug is within the range where the anti-slip concave-convex portion can be fitted with the anti-deviation protrusion of the plug holding wall, The protrusion is arranged on the inner wall of the storage box.

Therefore, when the connector plug is accommodated in the storage box, even if the holding positions of the connector plug are one behind the other, as long as at least one anti-deviation protrusion can be fitted in the plug front-rear direction restricting wall, fit in the anti-slip concave-convex part. Therefore, even if the connector plug is accidentally inserted between the pair of plug holding walls, the pair of plug holding walls can prevent displacement in the front-rear direction and securely hold the connector plug.

Furthermore, the electric component is an external antenna for wireless communication, and is accommodated together with a wireless communication card incorporating a wireless communication function.

In this case, the connector plug at the tip of the cable leading out from the external antenna can be carried away with the wireless communication card in a state where the connector plug at the tip of the cable drawn out from the external antenna is securely maintained, which is excellent in portability.

Detailed ways

The storage box related to an embodiment of the present invention will be described in detail below according to the accompanying drawings.

The wireless communication card storage box 1 of this embodiment is a synthetic resin storage box as shown in FIGS. And the connector plug 31 that is arranged on the front end of the connecting cable 7 drawn out from the root of the external antenna 5 .

The wireless communication card storage box 1 includes: a flat box-shaped box main body 9 for storing the external antenna 5, the connection cable 7 and the connector plug 31 at predetermined positions; The flat cover 11 that accommodates the PC card modem 3 is housed.

Referring to Fig. 4 simultaneously, described box main body 9 comprises: flat rectangular top plate 13, vertically arranged on the side walls 15L, 15R and vertically arranged on the side walls 15L, 15R along the longitudinal direction of the top plate 13 (left and right edges in Fig. 3 ) The front wall 17 at the front end edge (right end edge in FIG. 2 ) in the longitudinal direction.

And, the rear wall 19 that is vertically arranged at the rear end portion (left end portion in FIG. 2 ) of the longitudinal direction of the top plate 13 is in contact with the front end of the upper wall of the pocket portion 71 that will be described later and is arranged on the cover body 11. Be about the height of box main body 9 half.

The rear ends of the two side walls 15L, 15R protrude rearward from the rear wall 19 as shown in FIG. 4 . In order to allow the lid body 11 to pivot freely on the respective inner surfaces, cylindrical rotation shaft protrusions 25 are provided protrudingly. On the two side surfaces corresponding to the cover body 11 , recesses for the rotating shaft (not shown in the figure) are recessed and provided with the protrusions 25 for the rotating shaft.

And accommodate in the box main body 9: the external antenna 5 as mentioned above, the connection cable 7 and the connector plug 31 that connect the external antenna 5 to the PC card modem 3, and the connector plug 31 is installed on the connection. The front end of the cable 7 is also used to connect to the connection part 70 of the case part 69 in the PC card modem 3 .

The external antenna 5 is, as shown in FIG. 1 , a so-called bushing antenna having a substantially round rod shape, and includes a large-diameter portion 35 on the root side connected to the connection cable 7 and a small-diameter portion 33 extending to the front end through a conical portion 37 .

The connecting cable 7 is installed on the root of the external antenna 5 in a direction perpendicular to the central axis of the external antenna 5 via the connecting portion 39 .

On the other hand, the external antenna 5 is accommodated along the side wall 15L of the case main body 9 as shown in FIG. 4 .

Also, at the base (lower end in FIG. 4 ) of the external antenna, as shown enlarged in FIG. The pivot shaft prevents the movement to the right angle direction of the axis, and at the same time, the conical fitting protrusion 43 that can rotate around the center line to hold the external antenna 5 is provided on the rear wall of the box main body 9 as an antenna fitting portion. 19 on the inner surface.

On the other hand, in the state where the fitting protrusion 43 is fitted into the fitting recess 41 of the external antenna 5, the top plate 13 located at the front end portion (the upper end portion in FIG. 4 ) of the external antenna 5 An elastic flexible piece 45 protrudes from the inner surface. The elastically flexible piece 45 biases the front end of the external antenna 5 against the root side by its elastic restoring force, thereby maintaining the fitting state of the fitting recess 41 with respect to the fitting protrusion 43 .

And in the state where the fitting protrusion 43 is fitted in the fitting recess 41 of the external antenna 5, a through hole 49 is formed on the inner surface of the top plate 13 located at the conical portion 37 of the external antenna 5. The antenna is held with ribs 47 . The inner diameter of the through hole 49 is larger than the small diameter portion 33 of the external antenna 5 and smaller than the large diameter portion 35 .

When storing and maintaining the external antenna 5 in the box main body 9, at first the front end of the small diameter portion 33 of the external antenna 5 is passed through the through hole of the antenna holding rib 47 from the lower side in FIG. The front end of the portion 33 is pressed against the elastic flexible piece 45 to bend.

Next, in this state, the fitting recess 41 provided at the base of the external antenna 5 is fitted into the fitting protrusion of the case main body 9 . In this way, due to the elastic recovery force of the elastic flexible sheet 45, the fitting recess 41 of the external antenna 5 is pressed against the fitting protrusion 43 of the box main body 9 to fit, so that the external antenna 5 can be reliably rotated around the axis. maintained.

On the inner surface of the top plate 13 of the box main body 9 , as shown in FIGS. 1 to 4 , a cable holding guide 51 for holding the connection cable 7 at a predetermined position is integrally formed. The cable holding guide groove 51 is composed of elliptical inner wall ribs 53 and outer wall ribs 55 arranged parallel to the inner wall 53 at a certain interval for sandwiching the connection cable 7 between the inner wall ribs.

Also, as shown in FIG. 4 , a connector plug holding portion 57 for fixing the connector plug 31 is provided inside the inner wall rib 53 .

The connector plug holding portion 57 is composed of a pair of left and right plug holding walls 61, 61 at positions corresponding to the unlocking knob portions 59, 59 provided on both sides of the connector plug 31, and restricting the direction of the connector plug 31 to the corresponding position. The plug front restricting wall 63 in the range of forward movement and the plug rear restricting walls 65 and 65 in the range of restricting the backward movement of the connector plug 31 are formed integrally on the back of the top plate 13 of the box main body 9 .

Described unlocking knob part 59,59 as shown in Figure 5 and Figure 6, is the parts of unlocking mechanism, and this locking mechanism is when connector plug 31 is connected on the PC card modem 3, in order to prevent falling off, make it Locking, provided on both sides of the connector plug.

And these unlocking knobs 59, 59 keep the parts that are squeezed inward as much as possible when the lock is released, and are constantly pressed outward with elastic restoring force such as a spring, so that they can return to the locked position as soon as the hand is released.

As shown in FIG. 6 , the distance b between the inner surfaces of the pair of plug holding walls 61 , 61 erected on the inner surface of the top plate 13 is usually set to be larger than the distance b between the outer surfaces of the left and right unlocking knobs 59 , 59 . B is small so that these unlocking knobs 59, 59 can be clamped in the squeezed and spring-pressed state.

Therefore, when the connector plug 31 provided at the front end of the connection cable 7 drawn out from the external antenna 5 is housed in the case main body 9 together with the external antenna 5, the unlocking knob 59, 59. Clamp the pair of plug holding walls 61 and 61 in a state of pressing and springing.

Therefore, since the connector plug 31 is clamped between the pair of plug holding walls 61, 61 by the elastic restoring force of its own unlocking knobs 59, 59, the plug holding wall 61 itself does not need to be elastically deformed. It is also unnecessary to form a concave stopper protrusion 101 like the flexible stopper piece 103 shown in FIGS. 10 and 11 .

In addition, since the unlocking knobs 59 and 59 are always biased outward by elastic restoring force such as the above-mentioned spring, they have sufficient elastic travel and durability in advance, so they can be held stably after a long period of use. force.

Furthermore, as also shown in FIG. 7 , serrations 60 are provided on the outer surface of the unlocking knob 59 as concave-convex portions for anti-slip. Since the serrated part 60 is used to prevent the fingertips from slipping when the connector plug 31 is grasped and pulled out from the connection part 70 of the PC card modem 3, it is along the front and rear direction of the plug (connector plug). The insertion and removal direction) the concave and convex part of the section waveform.

On the other hand, on the opposite side (back side) of the pair of plug holding walls 61, 61, a plurality of (for example, three here) anti-corrosion holes of different sizes are fitted on the concavo-convex portion of the serrated portion 60 . The offset protrusion 62 is integrally formed as a rib protrusion extending on a straight line in the vertical direction (direction perpendicular to the inner wall surface of the storage box).

That is, since the anti-deviation protrusion 62 is a rib protruding in a direction perpendicular to the inner wall surface of the storage box 9 (the moving direction of the metal mold), it will not form a depression, and the forming metal mold will not be complicated, thereby improving the quality of the mold. manufacturing cost.

Therefore, once the connector plug 31 is inserted between the pair of plug holding walls 61, 61, since the anti-offset protrusion 62 provided opposite to the plug holding wall 61 fits into the unlocking lock provided on the connector plug 31, Since the unevenness of the sawtooth portion 60 on the knob 59 is centered, the connector plug 31 can be prevented from being deviated in the front-rear direction, and can be reliably held.

Moreover, since the anti-deviation protrusion 62 protrudes in a plurality along the plug front-rear direction of the connector plug 31, when the connector plug 31 is accommodated in the box main body 9, due to the connection cable 7 Influenced by the storage state, relative to the connector plug holding part 57, even if the holding position of the connector plug 31 is one in front and one behind, as long as at least one anti-deviation protrusion 62 fits in the concave part of the serrated part 60, a pair The plug holding walls 61 , 61 can prevent the front-rear direction deviation and securely hold the connector plug 31 .

The maximum distance H that the connector plug 31 can move in the forward and backward direction, which is restricted by the plug front restricting wall 63 and the plug rear restricting walls 65 and 65, becomes the length of the plug holding walls 61 and 61 as shown in FIGS. 7 and 8 . At least one of the displacement preventing protrusions 62 fits in the recess of the serrated portion 60 of the unlocking knob 59 .

That is, the distance h1 from the misalignment preventing protrusions 62 at both ends and the distance h2 from the recesses at both ends of the serration 60 form H≦h1+h2.

Therefore, when the connection cable 7 is accommodated along the cable guide 51, the position of the connector plug 31 in the front-rear direction relative to the connector plug holding portion 57 is offset only by H, and the plug holding walls 61, 61 are used. The connector plug 31 can also be held securely.

In addition, it is preferable that between the plug-holding walls 61, 61 and the rear restricting walls 65, 65, a piece of the connector plug 31 is provided so that the operator's fingers can be easily removed from the connector plug holding portion 57. accessible gap.

The PC card modem 3 is composed of a housing part 69 with a built-in wireless communication function, a flat PC card part 67 protruding from the lower end of the housing part 69, and an antenna 68 freely foldable and arranged on the upper part of the housing part 69. Composition, the connector plug 31 is connected to the connector part 70 provided on the back.

Then, by inserting the front end portion of the PC card portion 67 into the bag portion 71 (refer to FIG. 1 ) provided on the cover body 11, when the cover body 11 is closed, the cable holding guide groove 51 of the box main body 9 and the The connector plug holding portion 57 is overlapped, and the PC card modem 3 is stored in the wireless communication card storage case 1 .

That is, the thin plate-shaped PC card portion 67 of the PC card modem 3 is overlapped and accommodated in the above-mentioned cable holding guide 51 and the connector plug holding portion 57 . Since the case portion 69 protruding thicker than the PC card portion 67 is accommodated in a space (space on the right side in FIG. 2 ) that does not interfere with the cable holding guide 51, the thickness of the wireless communication card storage case 1 can be minimum.

Therefore, although the wireless communication card storage box 1 of this embodiment houses the external antenna 5 together with the PC card modem 3 as a whole, it can also be made small in appearance and miniaturized.

Also, in the state of reliably maintaining the connector plug 31 provided at the front end of the connecting antenna 7 drawn out from the external antenna 5, they can be taken together with the PC card modem, and the portability is good.

When using the PC card modem 3 and the external antenna 5, the rotation axis is used as the center of rotation with the protrusion 25, the cover body 11 is rotated and opened relative to the box main body 9, and the PC card modem 3 taken out is inserted into the PC card 105. PC card slot connection.

Next, the connection cable 7 is drawn out with the external antenna 5 housed in the case main body 9, and the connector plug 31 is connected to the connection portion 70 of the PC card modem 3 as shown in FIG. 5 .

At this time, since the external antenna 5 is held by the case main body 9 in a rotatable state around the axis, the connecting cable 7 can be guided in a desired direction.

And after making the cover 11 rotate more than 270 degrees relative to the box main body 9, the rotation is restricted due to the rear wall 19 of the box main body 9 being in contact with the outer surface of the cover 11. As shown in FIG. 5, the opening angle of the box main body 9 and the cover body 11 is kept substantially perpendicular.

Therefore, since the cover body 11 becomes a base, the wireless communication card storage box 1 is placed on a horizontal platform, and the external antenna 5 in the state of being stored in the box main body 9 as it is is maintained in a substantially perpendicular direction with respect to the table surface. angle.

In addition, in consideration of the gain of the external antenna 5, it is preferable that the angle with respect to the table top exceeds 70 degrees. However, when the angle with respect to the table is close to 90 degrees or more than 90 degrees, the box main body 9 may fall down, so an angle smaller than 90 degrees is made.

Furthermore, the connector plug holding portion of the storage box of the present invention is not limited to the structure of the connector plug holding portion 57 in the above-mentioned embodiment, and of course various forms can be adopted.

For example, although in the above-described embodiment, the three misalignment prevention protrusions 62 protrude from the opposite side of the plug holding wall 61, the present invention is not limited thereto.

Moreover, in the above-mentioned embodiment, the storage case 1 for a wireless communication card which accommodates the external antenna 3 for wireless communication which is an electrical component was demonstrated as the storage case of this invention. But the present invention is not limited thereto. For example, any storage case can be applied as long as it is a storage case for accommodating electrical components such as connector plugs provided at the tips of cables drawn from various electrical components such as headphones and microphones.

Although the present invention has been described in detail with reference to specific embodiments, it is clear to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the present invention.

This application is based on Japanese Patent Application (Patent Application No. 2001-100497) filed on March 30, 2001, the contents of which are incorporated herein by reference.

According to the storage box of the present invention as described above, when the connector plug provided at the front end of the cable drawn out from the electrical component is stored in the storage box together with the electrical component, the pair of plug holding walls are pressed and spring-pressed. Attach the locking release knob that clamps the connector plug.

Since the connector plug is sandwiched between the pair of plug holding walls by the elastic restoration of the lock release knob itself, the plug holding walls themselves do not need to be elastically deformed, nor are the stopper projections forming the depressions necessary. Therefore, there will be no problem that the metal mold for forming the storage box is complicated and the manufacturing cost increases.

In addition, the unlocking knob is a member that is always biased outward by the elastic restoring force of a spring or the like in advance, and since it has sufficient elastic stroke and durability, it can maintain a stable holding force over a long period of time.
