Description

  The present invention relates to a terminal cover mounting structure of a terminal device and a terminal device including the terminal cover mounting structure.

  In recent terminal devices typified by mobile phones, connection with external devices is indispensable in order to exchange large amounts of data or charge the data. Therefore, a terminal device having an external connection terminal is common.

  The external connection terminal in the terminal device is normally exposed on the outer surface, and a terminal cover that closes the external connection terminal is required to prevent intrusion of dust or dust or damage due to external force. In addition, a terminal cover that is openable and closable according to the use of the external connection terminal and is always connected to the terminal device so as not to be lost away from the terminal device is desirable. However, complicated and large parts and troublesome attachment work are not preferable for recent terminal devices that are becoming smaller, lighter and thinner. Therefore, there is a demand for a terminal cover that has a simple component configuration and can be attached with a simple operation and is not easily detached.

  9 and 10 show an example of a conventional terminal cover mounting structure in a mobile phone.

  The holding portion 124 provided so as to protrude from the cover portion 121 of the terminal cover 102 is formed of an elastically deformable member, and is inserted into the hole portion 103 provided in the mobile phone body 4 to hold the terminal cover 102. The holding part 124 has an arrowhead-shaped head part 125, and a notch part 128 is provided at the tip of the head part 125.

  The hole 103 is formed such that the width L0 of the inlet is smaller than the width A0 of the head 125 of the holding part 124, and further the width becomes narrower from the inlet toward the back. When the holding portion 124 is inserted there, the cutout portion 128 is contracted, and the head portion 125 enters deeply while being elastically deformed (FIGS. 11 and 12). When the head 125 passes through the hole 103, the claw 129 is caught in the opening at the back, and the holding part 124 is not pulled out (FIGS. 13 and 14).

  In the mounting structure described above, in order to make the terminal cover difficult to remove, for example, the claw portion may be enlarged or the holding portion may be formed of a member having a large resistance against elastic deformation. However, in such a case, it is difficult to attach the terminal cover, resulting in difficulty in assembling work. On the other hand, when priority is given to ease of attachment, the terminal cover cannot obtain sufficient pull-out strength. As described above, the conventional mounting structure has a problem that the assembling property and the pullout strength are contradictory.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a terminal cover mounting structure for a terminal device in which the terminal cover is easily mounted, is not easily detached, and has sufficient pulling strength. Another object of the present invention is to provide a terminal device having such a terminal cover mounting structure.

  In order to achieve the above-described object, the terminal cover mounting structure of the present invention includes a hole provided in a terminal device, a cover portion that closes an external connection terminal of the terminal device, and is attached to the cover portion. A terminal cover having an elastically deformable holding portion that is inserted into the hole portion and holds the cover portion on the terminal device, and the inside of the hole portion includes the first side surface and the first side. A slope portion extending obliquely with respect to the insertion direction of the holding portion from the entrance of the hole portion toward the second side surface. A first engaging portion is provided on the second side surface, the insertion of the holding portion is allowed at a position facing the second side surface of the holding portion, and the holding portion is A second engagement that engages with the first engagement portion to prevent extraction when it is about to be extracted. Part is provided. Moreover, the terminal device of this invention is equipped with the attachment structure of the terminal cover as described above.

  As described above, according to the present invention, it is possible to provide a terminal cover mounting structure in which the terminal cover is easily attached and hardly detached, and has sufficient pull-out strength, and a terminal device including the terminal cover mounting structure. it can.

  1 to 2 show an embodiment in which the present invention is applied to a mobile phone as a terminal device.

  FIG. 1A shows a state in which a terminal cover 2 is attached to the mobile phone body 1. FIG. 1 (b) shows the mobile phone body 1 with the terminal cover 2 removed, and FIG. 1 (c) is an enlarged view thereof.

  A concave portion 11 is provided on one side surface 19 of the mobile phone body 1. The recess 11 is provided with an external connection terminal 12 and a hole 3, and the hole 3 is used for attaching the terminal cover 2 to the mobile phone body 1. Further, an engagement groove 13 is provided on the inner peripheral edge thereof. The hole 3 will be described in detail with reference to FIG.

  2A is a front view of the mobile phone body 1 and the terminal cover 2, and FIG. 2B is an enlarged view thereof. The terminal cover 2 includes a cover portion 21 and a holding portion 24 provided so as to protrude from the cover portion 21. The holding part 24 is made of an elastically deformable member made of a material such as an elastomer, for example, and includes a head part 25 and a body part 26 having a width A2 smaller than the width A1 of the head part 25. By attaching the holding portion 24 to the hole portion 3, the cover portion 21 for covering the external connection terminal 12 can be held by the mobile phone body 1. A second engagement portion 27 that prevents the holding portion 24 from being pulled out from the hole portion 3 is installed at the tip of the head portion 25.

  The cover portion 21 is provided with an engaging protrusion 23 on the outer peripheral edge thereof. The engagement protrusion 23 engages with the engagement groove 13 of the recess 11, whereby the cover portion 21 is detachably attached to the mobile phone body 1 so as to close the recess 11. When using the external connection terminal 12, the external connection terminal 12 can be exposed by elastically deforming the hinge portion 22 formed thinly on the cover portion 21 and bending one end of the cover portion 21. is there.

  Next, in order to describe the hole 3 in detail, a side view and an enlarged view of the mobile phone body 1 and the terminal cover 2 are shown in FIGS. 3 (a) and 3 (b). FIG. 3C is a view of the opening of the hole 3 as viewed from the front.

  The hole 3 is divided into two parts. They are a first portion 34 that serves as an insertion position for the holding portion 24 of the terminal cover 2 and a second portion 36 that serves as a receiving position.

  The first portion 34 corresponds to the upper portion inside the hole 3 as seen in the side view shown in FIG. The first side surface 31 facing the first portion 34 is provided with an inclined surface portion 33 extending from the entrance of the hole portion 3 toward the back toward the second side surface 32 on the lower side facing the first side surface 31. It has been. The opening portion of the first portion 34 is formed so that the width L1 is larger than the width A1 of the head portion 25 of the holding portion 24 (see FIG. 2B). Further, the height H of the opening is also formed larger than the thickness T of the head 25 of the holding part 24. Therefore, when the holding portion 24 is inserted into the hole portion 3, it is inserted from the first portion 34.

  On the other hand, the second portion 36 corresponds to a lower portion inside the hole portion 3 as seen in the side view shown in FIG. 3B and is sandwiched between the second side surface 32 and the first portion 34. It is a part that. In the vicinity of the entrance of the second portion 36, as shown in FIG. 3C, a pair of retaining portions 37 are provided on both the left and right sides as viewed from the opening side. The interval between the retaining portions 37 at the entrance, that is, the width L2 of the opening of the second portion 36 is smaller than the width A1 of the head portion 25 of the holding portion 24, and the width A2 of the trunk portion 26 (FIG. 2 ( It is formed larger than b). Further, as shown in FIG. 2B, the distance L <b> 3 between the retaining portions 37 is formed so as to gradually widen from the entrance to the back according to the shape of the head 25. Accordingly, the second portion 36 is configured such that the holding portion 24 cannot be entered from the inlet, but the holding portion 24 can be received therein. Further, the portion corresponding to the inner end of the second side surface 32 is a first engagement portion 35 that engages with a second engagement portion 27 provided in the holding portion 24.

  Next, a method for attaching the holding portion 24 to the hole portion 3 will be described with reference to FIGS.

  As described above, the holding portion 24 is inserted from the first portion 34 into the hole portion 3. Then, the tip of the head 25 first contacts the slope portion 33 (FIG. 4). When further inserted, the holding portion 24 tends to move toward the second side surface 32 by the inclined surface portion 33. However, since the width A <b> 1 of the head 25 is larger than the distance L <b> 3 between the retaining portions 37, the head 25 cannot move to the second portion 36 as a whole until the head 25 passes through the retaining portions 37. Therefore, the holding part 24 slides to the back while being elastically deformed along the slope direction of the slope part 33 (FIG. 5). When the head portion 25 is inserted until it completely passes through the retaining portion 37, the holding portion 24 moves to the second portion 36 and is received between the retaining portion 37 that is the receiving position (see FIGS. 6 and 6). 7). Further, the terminal cover 2 can be attached to the mobile phone body 1 as shown in FIG. 1A by being inserted and engaging the engagement protrusion 23 of the cover portion 21 with the engagement groove 13 of the recess 11. it can.

  As described above, since the inclined surface portion 33 is provided on one side surface of the hole portion 3, the holding portion 24 of the terminal cover 2 can be easily attached.

  Next, a case will be described in which the holding portion 24 is once received in the second portion 36 and the holding portion 24 is to be pulled out from the opening portion of the second portion 36 in the horizontal direction. The terminal cover 2 can be pulled out to the position shown in FIGS. However, even if it is attempted to be pulled out further, the second engagement portion 27 of the holding portion 24 and the first engagement portion 35 of the second side surface 32 are engaged, and the head portion 25 is prevented from coming off. Since it cannot pass between, holding | maintenance part 24 is not pulled out.

  Further, with reference to FIG. 8, a case where the holding portion 24 is to be pulled out from the opening portion of the first portion 34 in an oblique direction will be described. Since the second engaging portion 27 of the holding portion 24 is engaged with the first engaging portion 35, the holding portion 24 naturally does not move in the horizontal direction (inlet direction). Moreover, since the slope portion 33 serves as a stopper, the head portion 25 of the holding portion 24 does not move in the vertical direction (the direction of the first portion 34). Therefore, even if it is attempted to pull out the holding portion 24 from the opening portion of the first portion 34, it cannot be easily removed.

  In this way, the inclined surface portion 33 plays not only a role of a guide when the terminal cover 2 is inserted, but also a role of preventing pulling out.

  The position and shape of the slope portion 33 and the retaining portion 37 and the shape of the holding portion 24 are not limited to those shown in the above embodiment. For example, the insertability and pull-out strength of the holding part 24 can be adjusted by changing the position and inclination of the slope part 33 and the arrangement of the retaining part 37 according to the shape of the holding part 24.

  Moreover, although the embodiment implemented in the mobile phone has been described above, the present invention can also be implemented in other terminal devices.
