Description

  The present invention relates to a lid member. In particular, in order to allow an opening provided in a housing of an electronic device to be closed by the lid portion, a system stop portion is communicated with the lid portion, and the system stop portion is formed in the opening. The present invention relates to a lid member configured to be fitted into an adjacent locking hole.

  In recent years, mobile terminals such as mobile phones have been frequently used. The portable terminal 100 is provided with a display unit and an antenna at the top of the housing, and an operation unit is provided below the display unit. By operating the operation unit, the portable terminal 100 can be used as a mobile phone or a portable information terminal. It is used as a communication means.

  When used as a communication means of a portable information terminal, it is necessary to connect to the portable information terminal. For this reason, the connector for communication is provided in order to connect a portable information terminal with a portable information terminal. Alternatively, some have a connector for charging to charge the portable terminal.

This connector is provided, for example, at the bottom of the casing, and is disposed so as to be connectable from the outside of the casing by facing the opening of the casing.
When the connector is not used, the connector is protected by closing the opening with a lid member.
The lid member is coupled to the housing so as not to drop off from the housing when the connector is used (when the opening is released) (see, for example, Patent Document 1).
JP 11-195450 A

The lid member of Patent Document is provided with an attachment hole in the connecting portion and a notch communicating with the attachment hole. The notch is inserted into a boss on the housing side, and the connecting portion is pushed toward the housing in this state, so that the mounting hole is fitted into the boss and the lid member is coupled to the housing.
The lid member of the patent document is easy to attach to the housing side, but because the notch communicates with the mounting hole, it easily falls off the housing.

In order to make it difficult to drop off from the housing, a lid member 70 shown in FIG. 6 can be considered. The lid member 70 is provided with a connecting portion 72 in the lid portion 71, a substantially arrowhead-shaped system stop portion 73 is provided in the connection portion 72, and a through-hole 74 is provided in the system stop portion 73, so The stopper 73 is made flexible.
According to this lid member 70, the system stop 73 is tapered by forming the tip end surface 73 a side of the system stop 73 in the shape of an arrowhead, and the system stop 73 is flexible through the through hole 74. The system stop 73 is easily fitted into the locking hole 77 of the casing 76 as shown by the arrow.

Moreover, the base end surface 73b side of the system stop part 73 is overhanging by forming the system stop part 73 in arrowhead shape. Therefore, after the system stop 73 is fitted into the locking hole 77, the base end face 73 b side is spread outside the locking hole 77 and is prevented from coming out of the locking hole 77.
This makes it possible to make the force required when the system stop 73 is attached and the force required when the system stop 73 fall off, making it difficult for the system stop 73, that is, the lid member 70, to drop off from the housing 76.

However, it is difficult to ensure a sufficient amount of bending of the system stopper 73, that is, an amount of elastic deformation only by providing the through-hole 74 in the system stopper 73.
For this reason, when the system stopper 73 is inserted into the locking hole 77, a portion other than the locking part 73, for example, the connecting part 72 connected to the lid 71 is bent, and it takes time to insert the system stopper 73. This can be considered.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a lid member that can easily and surely insert a system stop portion into a locking hole and is less likely to drop off.

  The lid member of the present invention includes a lid portion capable of closing an opening provided in a casing of an electronic device, a substantially band-like and substantially arrowhead-like system stop portion coupled to the lid portion, and the opening. A lid member that can be held so that the lid portion does not fall off from the housing when the lid portion opens the opening by being fitted into the locking hole adjacent to And it has the slit formed toward the said cover part from the front end surface of the said system stop part, It is characterized by the above-mentioned.

By forming the slit from the distal end surface of the system stop portion toward the lid portion, the front end surface side of the system stop portion is easily elastically deformed inward.
Thereby, when inserting into the locking hole from the distal end surface of the system stopper, the distal surface side of the system stopper can be elastically deformed satisfactorily, and the system stopper can be smoothly and reliably fitted into the locking hole. .

On the other hand, by forming the slit from the distal end surface of the system stop portion toward the lid portion, the base end side of the system stop portion can be kept in a state where it is relatively difficult to be elastically deformed.
As a result, even if a force is applied to the system stop portion to be extracted from the locking hole, the system stop portion is not elastically deformed, and the state locked to the locking hole is maintained.

  Moreover, the lid member of the present invention has a through hole formed along the thickness direction of the system stop.

  By forming the through hole along the thickness direction of the system stop, the system stop is more easily elastically deformed. As a result, when inserting into the locking hole from the tip surface of the system stopper, the tip surface side of the system stopper is elastically deformed more satisfactorily, and the system stopper is more smoothly and more securely in the locking hole. Can be securely inserted.

  The lid member of the present invention is characterized in that a thin portion having a thickness dimension less than the thickness dimension of the system stop portion is provided in the slit.

Here, in consideration of manufacturing tolerances and the like, it is conceivable that by providing a slit in the system stop part, the system stop part is easily elastically deformed, and the system stop part is easily detached from the locking hole. As a countermeasure, it is required to maintain the slit shape with high accuracy.
For this reason, it is necessary to improve the injection molding accuracy of the lid member, which may hinder cost reduction.

Therefore, in claim 3, a thin portion is provided in the slit, and the thin portion is formed to have a thickness dimension less than the thickness dimension of the system stop portion. By providing this thin portion in the slit, the system stop can be easily adjusted to a desired elastic strength.
In particular, the thin wall portion is gradually elastically deformed when a load is slowly applied, such as when the system stop portion is fitted into the locking hole, but when the system stop portion is extracted from the system stop hole, When a load is applied suddenly, elastic deformation is difficult.
Thereby, the adjustment which makes it easy to elastically deform the front end surface side of a system stop part, and makes it difficult to elastically deform the base end side of a system stop part can be performed easily.

  According to the present invention, a slit is formed from the distal end surface of the system stop portion toward the lid portion so that the front end surface side of the system stop portion is easily elastically deformed, and the proximal end side of the system stop portion is hardly elastically deformed. By this, it has the effect that the system stop part can be easily and surely fitted into the locking hole, and a lid member that is less likely to drop off can be provided.

  As shown in FIG. 1, the mobile terminal 10 as an electronic device is provided with a display unit 12 and an antenna 13 at the top of a housing 11 and an operation unit 14 below the display unit 12. By operating, it can be used as a mobile phone or as a communication means of a portable information terminal (not shown).

The portable terminal 10 needs to be connected to the portable information terminal when used as a communication unit of the portable information terminal.
For this reason, the mobile terminal 10 includes a connector 16 at the bottom 15 of the housing 11, and an opening 17 is provided in the bottom 15 so that the connector 16 faces the outside of the housing 11. A hole 18 is provided, and the opening 17 is opened and closed by the lid member 20 by locking the lid member 20 of the first embodiment in the locking hole 18.

  The lid member 20 of the first embodiment includes a lid portion 21 that can close the opening 17 provided in the housing 11, and a substantially band-like and substantially arrowhead-like system stop portion 22 connected to the lid portion 21. It is formed so that it can be held so that it does not fall off from the housing 11 when the lid 21 opens the opening 17 by fitting the system stop 22 into the locking hole 18 adjacent to the opening 17 while bending it. It is a member.

The lid portion 21 is formed in a substantially rectangular shape according to the opening 17, the connecting piece 24 of the system stop portion 22 extends from the lower portion 21 a toward the housing 11, and a pair of locking protrusions 26 are formed on the upper portion 22 b. A finger-hanging recess (not shown) is formed between the pair of protrusions 26.
The pair of locking projections 26 are projections for holding the lid portion 21 in the opening 17 by getting over the upper edge 17 a of the opening 17 and entering the inside of the housing 11 when the lid portion 21 closes the opening 17. is there.

When opening the opening 17, a finger is put on the above-described finger-hanging recess, and the lid portion 21 is pulled toward the outside of the housing 11.
As a result, the pair of locking projections 26 get over the upper edge 17a of the opening 17 and move to the outside of the housing 11, so that the lid 21 is opened and the opening 17 is opened.

The system stop portion 22 is a flexible member that is elastically deformable and includes a connecting piece 24 extending in a band shape from the lower portion 21 a of the lid portion 21 and a locking piece 25 protruding from the tip of the connecting piece 24.
The connecting piece 24 and the locking piece 25 are formed to have the same thickness.

  As shown in FIGS. 2 (A) and 2 (B), the locking piece 25 is formed by tapering the both sides 30a of the tip portion 30 so that the tip portion 30 is tapered in a substantially arrowhead shape. The end 32 protrudes outward from both side edges 24 a of the connecting piece 24.

  The locking piece 25 is formed with a slit 34 from the distal end surface (front end surface of the system stop portion) 30 b toward the base end portion 32 (that is, toward the lid portion 21). A thin portion 36 having a thickness dimension less than the thickness dimension of the (system stop portion) 25 is provided, and a pair of base end portions 32 and the connecting piece 24 behind the slit 34 are arranged along the thickness direction of the system stop portion 22. A through hole 38 is formed.

The slit 34 is formed so that the bottom 34 a thereof is flush with the base ends of the tapered side edges 30 a as indicated by an imaginary line 39, and from the bottom 34 a toward the opening end 34 b of the slit 34. It is formed in a substantially V shape so that the slit width gradually increases.
By forming the slit 34 in the distal end portion 30, a pair of introduction pieces 40 are formed on the distal end surface 30 b side of the system stop piece 25.

By forming the slit 34 from the distal end surface 30b of the system stop piece 25 toward the base end portion 32, a pair of introduction pieces 40 is formed, and it is easy to elastically deform inward.
Thereby, when inserting into the locking hole 18 (refer FIG. 1) from the front end surface 30b of the system stop piece 25, a pair of introduction piece 40 is elastically deformed favorably, and the system stop part 22 is made into the lock hole 18 smoothly. And can be inserted securely.

On the other hand, by forming the slit 34 from the distal end face 30b of the system stop piece 25 toward the base end part 32, the base end part 32 side of the system stop piece 25 can be kept in a state where it is relatively difficult to be elastically deformed.
As a result, even if a force to be pulled out from the locking hole 18 is applied to the system stopper 22, the system stopper 22 is not elastically deformed, and the state locked to the locking hole 18 is maintained. .

  Further, the bottom 34a of the slit 34 is formed so as to be flush with the base end of the tapered side 30a as indicated by an imaginary line 39, so that the slit 34 is bent, so that the locking portion 22 is locked to the locking hole 18. In addition, the resistance at the time of fitting into the locking hole 18 is reduced, and even if the system stopping portion 22 is forced to be pulled out from the locking hole 18, the locked state in the locking hole 18 can be maintained. .

The thin portion 36 is formed substantially at the center of the locking piece 25 in the thickness direction, and extends from the bottom 34 a of the slit 34 to the middle of the wall surface of the slit 34 toward the opening end 34 b.
By forming the thin portion 36 substantially at the center in the thickness direction of the locking piece 25, a step is formed between the upper surface of the thin portion 36 and the upper surface of the locking piece 25 and the lower surface of the thin portion 36 is locked. A step is formed on the lower surface of the piece 25.

  A thin portion 36 was provided in the slit 34, and the thin portion 36 was formed to have a thickness dimension less than the thickness dimension of the system stop piece 25. By providing the thin portion 36 in the slit 34, the system stopper 25 can be easily adjusted to a desired elastic strength.

In particular, the thin-walled portion 36 is gradually elastically deformed when a load is applied slowly, such as when the system stop 22 is fitted into the locking hole 18. However, it is difficult to elastically deform when a load is applied suddenly, such as when the system stop 22 is pulled out from the system stop hole 18.
Thereby, the adjustment which makes it easy to elastically deform the front end surface 30b side of the system stop piece 25 and makes it difficult to elastically deform the base end part 32 side of the system stop piece 25 can be easily performed.

The pair of through holes 38 are long holes formed at a predetermined interval in the longitudinal direction of the locking portion 22. By forming the through hole 38 along the thickness direction of the system stop 22, the system stop 22 is further easily elastically deformed.
As a result, when the tip end surface 30b of the system stop piece 25 is inserted into the locking hole 18 (see FIG. 1), the tip end surface 30b side of the system stop piece 25 is further elastically deformed, so that the system stop portion 22 is The engaging hole 18 can be more smoothly and reliably inserted.

Next, an example in which the lid member 10 of the first embodiment is attached to the housing will be described with reference to FIGS. 3 (A) to 3 (D).
As shown in FIG. 3A, when the tip 30 of the locking piece 25 is inserted into the locking hole 18 as shown by the arrow A, the taper pieces 30a on both sides hit both sides of the locking hole 18 at 18a.

As shown in FIG. 3B, in the state where the taper pieces 30 a on both sides are in contact with both sides of the locking hole 18, the system stopper 22 is further pushed toward the locking hole 18 as indicated by an arrow A.
As shown in FIG. 3C, this causes the thin portion 36 to be elastically deformed into a crushed state.
When the thin portion 36 is elastically deformed, the pair of introduction pieces 40 are elastically deformed inward as indicated by an arrow B.

From this state, by further pushing the system stop 22 toward the locking hole 18 as shown by the arrow A, the pair of introduction pieces 40 pass through the locking hole 18, and the base end portion 32 is locked in the locking hole 18. To reach.
Since the base end portion 32 is formed with the pair of through holes 38, both side sides 32 a of the base end portion 32 are elastically deformed so as to follow both side sides 18 a of the locking hole 18.

As shown in FIG. 3D, the base end portion 32 passes through the locking hole 18 and enters the inside of the housing 11 (see FIG. 1).
When the compressed base end portion 32 is restored by the restoring force, both side sides 32a of the base end portion 32 protrude to a state of protruding to the outside of the locking hole 18. This prevents the locking piece 25 from coming out of the locking hole 18.

Particularly, since the slit 34 is formed from the distal end surface 30b of the system stop piece 25 toward the base end portion 32 and the thin portion 36 is provided in the slit, the base end portion 32 side of the system stop piece 25 is relatively elastically deformed. It can be kept difficult.
As a result, even if a force to be pulled out from the locking hole 18 is applied to the system stopper 22, the system stopper 22 is not elastically deformed, and the state locked to the locking hole 18 is maintained. .

Next, a second embodiment will be described.
As shown in FIG. 4, the lid member 50 of the second embodiment includes a thin portion 51 instead of the thin portion 36 of the first embodiment, and other configurations are the same as those of the first embodiment.
The thin-walled portion 51 is formed at substantially the center in the thickness direction of the locking piece 25, and is formed with a predetermined width from the position toward the opening end 34b at a predetermined interval from the bottom 34a of the slit 34. It is.
By using the thin portion 51, it is possible to easily adjust the tip end surface 30b side of the system stop piece 25 to be easily elastically deformed and to make it difficult to elastically deform the base end portion 32 side of the system stop piece 25. .

  In the above-described embodiment, the example in which the opening 18 and the locking hole 18 are individually formed as the locking hole 18 adjacent to the opening 17 as shown in FIG. 1 has been described. However, the present invention is not limited to this. Thus, as shown in FIG. 5, the same effect can be obtained even if the locking hole 18 is formed integrally with the opening 17.

  In the above-described embodiment, the example in which the thin portions 36 and 51 are formed in the approximate center in the thickness direction of the locking piece 25 has been described. However, the present invention is not limited to this, and the bottom surfaces of the thin portions 36 and 51 are connected. It is also possible to form the stopper piece 25 so as to be flush with the bottom surface.

Furthermore, members, such as the front-end | tip part of the embodiment mentioned above, the slit 34, the through-hole 38, and the thick parts 36 and 51, are not limited to the illustrated shape, It can change suitably.
In addition, although the example in which two through holes 38 are provided in the locking portion 22 has been described, the number of the through holes 38 may be one, for example, and can be appropriately selected.

  In the present invention, in order to allow the opening of the housing of the electronic device to be closed by the lid, the system stop is communicated with the cover, and the system stop can be fitted into the locking hole adjacent to the opening. It is suitable for application to the configured lid member.
