Description

  The present invention relates to an electronic device such as a mobile phone, and more particularly to an electronic device characterized by a structure of a terminal cover for preventing dust from entering a connection terminal provided in the electronic device. .

  Generally, personal computers, PDAs, cameras, mobile phones, and the like, which are electronic devices, are equipped with connection terminals for connecting connectors from external devices to perform mutual data communication. In particular, in a portable electronic device, an opening is provided in a part of the housing in consideration of the portability of the device body, and a connection terminal is disposed in the opening. In many cases, the connection terminal is provided with a terminal cover for closing the opening when a connector from an external device is not connected. The terminal cover is for preventing dust from entering the connection terminal when the connector is not connected and protecting it from impacts and the like, and is formed of resin or rubber.

There are two types of terminal cover structures: a detachable type and a fixed type. The detachable terminal cover has a structure that can be removed from the electronic device. When the terminal cover is attached to the opening of the housing, the detachable terminal cover can be fitted to the unevenness of the structure of the connection terminal. However, since the detachable terminal cover having such a structure can be easily removed, it may be removed carelessly and the terminal cover may be lost.
On the other hand, a part of the terminal cover of the fixed terminal cover is supported by the housing, and the terminal cover can be opened and closed with respect to the opening with the supported portion as a fulcrum. However, the fixed terminal cover having such a structure may be difficult for a user who frequently uses a connector from an external device when the connector is inserted and removed, and the terminal cover becomes an obstacle.

Therefore, as disclosed in Patent Document 1, the terminal cover is sandwiched between the casing of the electronic device and the battery cover, and the terminal cover is accommodated in the casing when the connector is used, and the terminal cover is disconnected when the connector is not connected. There has been proposed a technique in which the is attached to the opening side of the housing. By doing in this way, while preventing loss of a terminal cover, insertion / extraction of a connector can be made easy.
JP 2001-185281 A

However, in the above-described prior art, since the terminal cover is sandwiched between the housing of the electronic device and the battery cover, each time the terminal cover is mounted on the opening side of the housing and stored inside the housing, each time. It is necessary to remove the battery cover. For this reason, there exists a subject that the operation | work which inserts / extracts the connector from an external device in the connection terminal of an electronic device takes time.
Further, since the battery cover is frequently removed, there is a possibility that the terminal cover may be lost when the battery cover is removed, and there is a problem that it cannot be an effective means for preventing the terminal cover from being lost.

  Therefore, the present invention provides an electronic device that can easily insert and remove a connector from an external device and can prevent loss of a terminal cover.

  In order to solve the above problems, the present invention provides an electronic device in which an opening is provided in a part of a housing and a connection terminal for an external device is provided in the opening. A terminal cover is provided, the terminal cover including a cover main body that closes the opening, and a tongue piece that extends from the cover main body toward the housing, and a slit is provided in the tongue piece. The housing is provided with a protrusion, and the slit includes a first slit extending along the insertion / extraction direction of the terminal cover and a second slit intersecting the first slit, and the protrusion includes the first slit. A protrusion main body standing upright and movable in one slit, and a head extending from the tip of the protrusion main body in a horizontal direction intersecting the first slit and passing through the second slit. Features.

  Further, the present invention provides an electronic device in which an opening is provided in a part of the housing, and a connection terminal with an external device is provided in the opening, and a terminal cover capable of opening and closing the opening by an insertion / extraction operation is provided, The terminal cover includes a cover main body that closes the opening, and a tongue piece that extends from the cover main body toward the housing. The terminal cover is provided with a plurality of slits, and the housing includes A plurality of protrusions corresponding to the plurality of slits are provided, and each of the plurality of slits includes a first slit extending along the insertion / extraction direction of the terminal cover and a second slit intersecting the first slit. The plurality of protrusions are respectively provided with a protrusion main body movably provided in the first slit, and extending in a horizontal direction intersecting the first slit from the tip of the protrusion main body. Passing Characterized in that it consists of an ability of the head.

  Furthermore, the present invention is characterized in that the length of the first slit is set longer than the length of the second slit.

  And this invention was formed so that said 2nd slit might be arrange | positioned between the said protrusion and the said cover main body in the state which obstruct | occluded the said opening part with the said cover main body.

  Further, the present invention is characterized in that the second slit is formed so as to be orthogonal to the first slit.

  Furthermore, the present invention is characterized in that at least the tongue piece portion of the terminal cover is formed of an elastic body.

  The present invention is characterized in that the width of the cover body and the width of the tongue piece portion substantially coincide.

According to the present invention, the terminal cover can be slidably attached in the insertion / removal direction of the connector by the first slit provided in the housing or the terminal cover of the electronic device. For this reason, if the cover body that closes the opening of the housing is slid in the direction away from the opening, the periphery of the connection terminal of the electronic device (the opening provided with the connection terminal) can be removed without removing the battery cover or the like. The space around which the connector can be easily inserted and removed can be ensured. Therefore, the connector from the external device can be easily inserted into and removed from the connection terminal.
Moreover, since the head part of the protrusion extended in the horizontal direction crossing the first slit and passing through the second slit is provided, it becomes difficult for the head part of the protrusion to easily come off the slit. That is, the terminal cover can be easily attached to the casing of the electronic device, but the terminal cover cannot be easily removed from the casing. Therefore, loss of the terminal cover can be prevented.

(First embodiment)
Next, a first embodiment of the present invention will be described based on the drawings.
FIG. 1 is a perspective view of a mobile phone 1 which is an electronic device. FIG. 2 is a view taken in the direction of arrow A in FIG.
As shown in FIG. 1, the mobile phone 1 includes a first housing 2, a second housing 3 that can be overlapped in the thickness direction of the first housing 2, and these two housings 2, 3. And a hinge portion 5 that is foldably connected to each other. The hinge portion 5 is disposed so as to connect the base end portions 4a and 4b of the two casings 2 and 3 to each other.

Inside the second housing 3, a display unit 7 having a display area 6 for displaying various information and a speaker 8 for calling are provided. The display unit 7 includes an LCD (LCD; Liquid Crystal Display) or an EL (EL; Electro Luminescence) display, etc., and the display area 6 of the display unit 7 is in a state where the two casings 2 and 3 are overlapped. It is provided so as to be exposed on the surface side of the second housing 3 facing the housing 2.
The speaker 8 for telephone call is disposed at the distal end of the second housing 3 located on the side opposite to the base end portion 4 b and penetrates from the surface of the second housing 3 to the internal space of the second housing 3. It is exposed to the outside through the opening 8a.

Inside the first housing 2, a key operation unit 12 having a plurality of operation keys such as a numeric keypad 9, a cursor key 10, or a function key 11, and a microphone 13 for a call are provided. The key operation unit 12 is exposed outward from the surface of the first housing 2 facing the second housing 3 in a state where the two housings 2 and 3 are overlapped with each other.
The microphone 13 is disposed at the distal end portion of the first housing 2 located on the side opposite to the base end portion 4 a, and is an opening that penetrates from the surface of the first housing 2 to the internal space of the first housing 2. It is exposed to the outside through 13a.

An internal battery 14 as a power source is detachably provided on the back surface of the first housing 2 opposite to the surface on which the plurality of operation keys 9, 10, 11 are exposed. A battery cover 15 is provided so as to cover the internal battery 14.
Furthermore, an opening 16 is formed at the tip of the first housing 2. A connection terminal 17 is provided in the opening 16. The connection terminal 17 is for performing data communication with each other by connecting a connector (for example, a communication I / O connector) connected to an external device (not shown). A terminal cover 18 that closes the opening 16 is attached to the opening 16.

FIG. 2 is a view taken in the direction of arrow A in FIG. 1 and shows a state where the battery cover 15 is removed. FIG. 3 is a perspective view of the terminal cover 18.
As shown in FIGS. 2 and 3, the terminal cover 18 is formed of a polymer material (elastomer) having rubber-like elasticity at room temperature, and has a substantially L-shaped cross section. . The terminal cover 18 includes a cover main body 19 that closes the opening 16, and a base end of the first housing 2 along the longitudinal direction of the first housing 2 from the cover main body 19 (connector insertion / extraction direction from an external device). A tongue piece 20 extending toward the portion 4a is integrally formed. The dimensions of the cover main body 19 and the tongue piece 20 in the width (left-right direction in FIG. 2) direction are set to substantially coincide with each other.

As shown in FIGS. 2 and 3, a substantially cross-shaped slit 21 is formed in the tongue piece 20. The slit 21 includes a first slit 22 that extends along the longitudinal direction of the first housing 2 and a second slit 23 that is orthogonal to the first slit 22.
The first slit 22 is formed at the approximate center of the tongue piece 20 in the width direction. The length of the first slit 22 is set longer than that of the second slit 23. The second slit 23 is formed closer to the cover body 19 from the approximate center of the first slit 22. Since the second slit 23 is formed orthogonal to the first slit 22, the second slit 23 extends along the width direction of the cover body 19.

  A recess 24 for accommodating the cover main body 19 is formed at the tip of the first housing 2 in a portion corresponding to the cover main body 19. In addition, a recess 25 for accommodating the tongue piece 20 is provided on the back surface of the first housing 2 in a portion corresponding to the tongue piece 20. On the bottom surface of the recess 25, a protrusion 26 is provided at a portion corresponding to the first slit 22 of the tongue piece 20. The protrusion 26 is closer to the base end portion 4a of the housing 2 than the second slit 23 (see FIG. 2) when the cover body 19 of the terminal cover 18 closes the opening 16 of the housing 2 (see FIG. 2). Near the upper side). That is, in a state where the cover main body 19 of the terminal cover 18 closes the opening 16 of the housing 2, the second slit 23 is arranged between the protrusion 26 and the cover main body 19.

4 is a cross-sectional view taken along line BB in FIG.
As shown in the figure, the protrusion 26 has a substantially T-shaped cross section, and has a protrusion body 27 corresponding to the slit width of the first slit 22 and a head provided at the tip of the protrusion body 27. The part 28 is integrally formed.
The protrusion body 27 is formed in a substantially cylindrical shape, and the height of the protrusion body 27 is set to be larger than the thickness d of the tongue piece 20. The head portion 28 is formed in a strip shape, and the center portion of the bottom surface is connected to the upper end portion of the projection main body 27. The head portion 28 is extended in the horizontal direction so that the longitudinal direction thereof is along the longitudinal direction of the second slit 23, that is, so as to be orthogonal to the first slit 22. The planar shape of the head portion 28 is formed so as to correspond to the planar shape of the second slit 23.

  For this reason, the protrusion 26 is in a state in which the dimension E1 of the head 28 is set larger than the dimension E2 of the protrusion body 27 in the width direction of the first housing 2 (left-right direction in FIG. 2). Therefore, in a state where the terminal cover 18 is set in the first housing 2 (see FIG. 2), it is difficult for the first slit 22 to pass through the head portion 28 of the protrusion 26. For this reason, the head 28 functions to prevent the terminal cover 18 from coming off from the protrusion main body 27. Therefore, once the terminal cover 18 is set in the first housing 2, the terminal cover 18 can be prevented from falling off the first housing 2.

Next, a method for setting the terminal cover 18 to the first housing 2 and the state of the terminal cover 18 when the connector from the external device is not connected to the connection terminal 17 and when it is connected will be described.
First, the battery cover 15 of the mobile phone 1 is removed from the first housing 2. Next, as shown in FIG. 5, while the cover main body 19 of the terminal cover 18 is directed in the direction in which the opening 16 of the first housing 2 can be closed (the back side in the drawing in FIG. 5), the tongue piece portion of the terminal cover 18. The second slit 23 formed in 20 is aligned with the head portion 28 of the protrusion 26 of the first housing 2, and the terminal cover 18 is pushed toward the first housing 2 side.

  At this time, the position where the protrusion 26 is disposed is closer to the base end 4 a side of the housing 2 than the position of the second slit 23 when the opening 16 is closed by the terminal cover 18. For this reason, although the cover main body 19 and the 1st housing | casing 2 will interfere, since the terminal cover 18 is formed with the elastomer, the terminal cover 18 elastically deforms. Therefore, the second slit 23 of the tongue piece 20 can be easily pushed into the head 28 of the protrusion 26.

When the head portion 28 completely passes through the second slit 23, the terminal cover 18 slightly moves toward the distal end side of the first housing 2 (downward in FIG. 5) due to the restoring force of the tongue piece portion 20. And the tongue piece 20 is housed in the recess 25 of the first housing 2 (the state of FIG. 2, the state of the terminal cover 18 when not connected to the connection terminal 17 of the connector from the external device). . At this time, since the concave portion 24 for housing the cover main body 19 is formed in the portion corresponding to the cover main body 19 at the tip of the first housing 2, the cover main body 19 protrudes from the first housing 2. There is no risk of losing aesthetics. Further, since the cover main body 19 is accommodated in the recess 24, the opening 16 can be reliably closed without the cover main body 19 being displaced even if a slight external force is applied to the terminal cover 18.
Thus, after setting the terminal cover 18 to the first housing 2, the battery cover 15 is attached to the first housing 2. Then, the setting of the terminal cover 18 to the first housing 2 is completed.

6 is a plan view showing a state in which the terminal cover 18 is slid, and FIG. 7 is a side view of FIG. FIG. 6 shows a state where the battery cover 15 is removed for convenience of explanation.
As shown in FIGS. 5 and 6, the terminal cover 18 has a first slit 22 formed in the tongue piece portion 20 and a concave portion 25 formed in the first housing 2, and the connector is inserted and removed from the external device. It can slide along the direction (vertical direction in FIG. 5) in the direction away from the opening 16 of the first housing 2 (downward in FIG. 5).

  Since the tongue piece 20 is formed of an elastomer, the terminal cover 18 that has been slid is easily elastically deformed toward the battery cover 15 side (downward in FIG. 6) with the tip 2a of the first housing 2 as a fulcrum. The cover body 19 can be retracted downward. For this reason, the space which can insert / extract the connector 29 from an external apparatus (not shown) around the connection terminal 17 (periphery of the opening part 16) easily can be secured. Therefore, the connector 29 can be easily inserted into and removed from the connection terminal 17.

In addition, it is desirable to set the distance L (see FIG. 5) between the cover main body 19 and the first housing 2 in a state in which the terminal cover 18 is slid, as long as possible. This is because by setting the distance L long, the distance from the tip 2a (fulcrum) of the first housing 2 to the cover body 19 becomes long, and the tongue piece 20 can be elastically deformed more easily. .
Further, in a state in which the terminal cover 18 is slid (see FIG. 5), the second slit 23 formed in the tongue piece 20 is disposed at a portion corresponding to the tip 2a of the first housing 2. It is desirable to do. In particular, the second slit 23 is disposed at a portion corresponding to the tip 2a of the first housing 2 in a state where the terminal cover 18 is slid to the maximum extent until the projection main body 27 contacts the back end of the first slit. Thus, it is desirable to form the protrusions 26 and the second slits 23. By doing in this way, the tongue piece part 20 of the slid state can be elastically deformed more easily.

  Here, in general, in this type of terminal cover, in order to easily elastically deform or bend the terminal cover that has been slid, the elastic deformation is performed using the tip 2a of the first housing 2 in this embodiment as a fulcrum. In many cases, a notch is provided in a portion to be bent. Thus, by providing a notch part, a part of terminal cover is made into thin shape, and the terminal cover is elastically deformed or bent by using the thin part as a fulcrum. However, in this embodiment, the second slit 23 is formed in the portion corresponding to the tip 2a of the first housing 2 of the tongue piece portion 20, thereby easily elastically deforming without providing a notch portion. Is possible.

  Therefore, according to the first embodiment described above, the terminal cover 18 is moved along the insertion / extraction direction of the connector 29 from the external device by the first slit 22 formed in the tongue piece portion 20 of the terminal cover 18. It can be slid in a direction away from the opening 16 of the body 2. Further, since the tongue piece 20 is formed of an elastomer, it can be easily elastically deformed. For this reason, without removing the battery cover 15, it is possible to secure a space that allows the connector 29 from an external device (not shown) to be easily inserted and removed around the connection terminal 17 (around the opening 16). Therefore, the connector 29 can be easily inserted into and removed from the connection terminal 17.

  Further, since the head portion 28 of the protrusion 26 that extends in the horizontal direction so as to be orthogonal to the first slit 22 and can pass through the second slit 23 is provided, the terminal cover 18 is easily attached to the first housing 2. For example, the terminal cover 18 can be prevented from falling off even when the battery cover 15 is removed from the first housing 2. For this reason, it is possible to prevent the terminal cover 18 from being lost.

  Furthermore, the head 28 of the protrusion 26 is provided so as to be orthogonal to the first slit 22, thereby preventing the terminal cover 18 from coming out of the first housing 2. For this reason, the size of the outer shape of the second slit 23 can be set larger than the size of the outer shape of the head 28. Therefore, the head 28 of the protrusion 26 can be smoothly passed through the second slit 23, and the terminal cover 18 can be attached to the first housing 2 more easily.

In the state where the cover main body 19 closes the opening 16 of the first housing 2 (the state of the terminal cover 18 when the connector 29 is not connected), the projection 26 is more than the second slit 23 in the first housing. 2, it is difficult to attach and detach the terminal cover 18 from the first housing 2. Therefore, for example, even if the terminal cover 18 is displaced in the direction away from the opening 16 (downward in FIG. 2), the terminal cover 18 is not inadvertently detached from the first housing 2.
Moreover, since the recessed parts 24 and 25 are formed in the part corresponding to the terminal cover 18 of the 1st housing | casing 2, it can prevent that the terminal cover 18 slip | deviates by external force. For this reason, while being able to protect from the penetration | invasion of the dust to the connection terminal 17, an impact, etc. reliably, without making the terminal cover 18 protrude from the 1st housing | casing 2, there is no possibility of impairing aesthetics. In particular, the recess 25 plays a role of guiding the terminal cover 18 in the sliding direction, and also has an effect of preventing the terminal cover 18 from rattling.

Further, the second slit 23 of the tongue piece 20 is disposed closer to the cover body 19 from the substantially longitudinal center of the first slit 22, that is, between the protrusion 26 and the cover body 19. Since the terminal cover 18 is formed, the second slit 23 does not pass through the protrusion 26 provided in the first housing 2 (see FIGS. 2 and 5). For this reason, when the terminal cover 18 is slid, there is no possibility that the second slit 23 is caught by the protrusion 26, and the terminal cover 18 can be smoothly slid.
Since the terminal cover 18 is formed of an elastomer, the tongue piece 20 is easily elastically deformed when the connector 29 is connected. Therefore, the insertion / extraction work of the connector 29 can be performed more easily.

  Further, by forming the slit 21 in the terminal cover 18 and providing the protrusion 26 on the first housing 2, the terminal cover 18 can be kept attached to the first housing 2, and the terminal cover 18 can be kept. Can be removed from the first housing 2. For this reason, it becomes possible to meet the needs of a wide range of users such as users who want to attach the terminal cover 18 to the mobile phone 1 and users who want to remove the terminal cover 18 from the mobile phone 1.

In addition, as shown in FIG. 8, you may provide the R part 30 formed in circular arc shape at the width direction both ends of the 2nd slit 23 formed orthogonally to the 1st slit 22. As shown in FIG. By providing the R portion 30 in this manner, the corners of the slit portion 21 can be reduced. For this reason, the part where the stress of the slit part 21 concentrates can be reduced, and it becomes possible to improve the durability of the terminal cover 18 itself.
Here, stress is likely to be applied to a portion that is generally formed at a right angle or the like (including a case where it is not an arc shape or an acute angle shape). Therefore, there is a possibility that a crack or the like may occur from a right angle portion of the slit. For this reason, it becomes possible to improve the durability of the terminal cover 18 itself by reducing the right angle portion (corner portion) of the slit. As a matter of course, the R portion 30 can be applied to both end portions of the first slit 22 in the longitudinal direction. Also in the second embodiment to be described later, the R portion 30 can be provided as appropriate.

(Second embodiment)
Next, a second embodiment of the present invention will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected and demonstrated to the same aspect as 1st embodiment.
FIG. 9 shows the terminal cover 40 according to the second embodiment, and is a plan view showing a state in which the battery cover 15 of the mobile phone 1 is removed. In the second embodiment, the terminal cover 40 has a substantially L-shaped cross section, and covers the opening 16 (see FIG. 1) of the mobile phone 1. The tongue piece 20 that extends toward the base end 4a side of the first housing 2 along the longitudinal direction of the one housing 2 (the direction in which the connector is inserted and removed from the external device) is integrally formed. The same as in the first embodiment.

  As shown in FIG. 9, the difference between the second embodiment and the first embodiment is that the tongue piece portion 20 of the terminal cover 18 in the first embodiment has one substantially cross-shaped slit 21. In contrast, the tongue piece portion 20 of the terminal cover 40 in the second embodiment is formed with a pair of substantially cross-shaped slits 21 and 21, and the width of the terminal cover 40 is The opening 41 is larger than the width of the terminal cover 18 and is larger than the opening 16 of the first embodiment, that is, the connector 29 from an external device (not shown) is larger than that of the first embodiment. It is in the point which can respond to the type.

These slits 21 and 21 are configured by first slits 22 a and 22 b extending along the longitudinal direction of the first housing 2 and second slits 23 and 23 orthogonal to the first slit.
The first slits 22 and 22 are distributed and arranged in the width direction around the center in the width direction of the tongue piece 20. The second slits 23 and 23 are formed closer to the cover body 19 from the approximate center of the first slits 22 and 22, respectively.

  On the back surface of the first housing 2, a recess 25 for storing the tongue piece 20 is provided in a portion corresponding to the tongue piece 20. On the bottom surface of the recess 25, a pair of protrusions 26 and 26 are provided at portions corresponding to the pair of first slits 22 a and 22 b of the tongue piece 20. The protrusions 26, 26 are closer to the base end 4 a of the housing 2 than the second slits 23, 23 in the state where the cover body 19 of the terminal cover 18 closes the opening 16 of the housing 2 (in FIG. 9). It is arranged on the upper side). That is, in a state where the cover body 19 of the terminal cover 40 closes the opening 16 of the housing 2, the second slits 23 and 23 are arranged between the protrusions 26 and 26 and the cover body 19. It has become.

  Therefore, according to the second embodiment described above, the same effects as those of the first embodiment are achieved. Further, when the size of the terminal cover 40 is large (in this second embodiment, the width of the terminal cover 40 is larger than that of the terminal cover 18 of the first embodiment), the slit 21 is formed in two. By forming the projections 26 at two locations and forming the projections 26 at the corresponding portions, the terminal cover 40 can be stably slid regardless of the size of the terminal cover 40.

Further, by forming the slits 21 and the protrusions 26 at two locations, the backlash of the terminal cover can be reduced as compared with the case where the slit 21 is provided at one location.
That is, as in the first embodiment described above, when there is only one slit 21, the first housing 2 is provided with a recess 25, and this recess 25 serves as a guide in the sliding direction of the terminal cover 18. At the same time, there is an effect of preventing the terminal cover 18 from rattling. However, when the slit 21 and the projection 26 are provided at two locations as in the second embodiment, the first housing 2 is provided with the recess 25. Even if it is not necessary, the sliding operation of the terminal cover 40 can be made stable.

As shown in FIG. 10, the second slits 23, 23 may be provided so as to extend outward from the first slits 22, 22 at right angles without being orthogonal to the first slits 22, 22. Good. Here, the second slits 23, 23 are integrally formed with slits 42, 42 extending from the outer end portion toward the base end portion 4 a side of the first housing 2, and the second slits 23, 23 are formed. It is substantially L-shaped.
In this case, it is desirable that the projections 26, 26 provided on the first housing 2 also have a shape corresponding to the shape of the slits 21, 21. By doing so, the fitting portions of the second slits 23, 23 (slits 42, 42) with respect to the protrusions 26, 26 are complicated, and as a result, the terminal cover 40 is unintentionally dropped from the first housing 21. It can be surely prevented.

The present invention is not limited to the above-described embodiment, and includes various modifications made to the above-described embodiment without departing from the spirit of the present invention.
In the first embodiment described above, the case where the first slit 22 and the second slit 23 are formed so as to be orthogonal to the tongue piece portion 20 of the terminal cover 18 has been described. In the second embodiment described above, the second slit 23 is provided so as to extend outward from the first slits 22 and 22 at right angles, and the second slit 23 is formed in a substantially L shape. Explained the case. However, the shape of the slit 21 is not limited to these, and the head portion 28 of the projection 26 formed so as to correspond to the second slit 23 functions to prevent the terminal cover 18 from coming off from the projection body 27. Any structure can be used.

And in the above-mentioned embodiment, although the case where the terminal cover 18 was formed with the elastomer was demonstrated, it is the structure in which at least the tongue piece part 20 has elasticity among the cover main body 19 and the tongue piece part 20 which comprise the terminal cover 18. I just need it.
In this case, the cover main body 19 may be formed of a hard resin and integrally formed with the cover main body 19 and the tongue piece 20 having elasticity. By doing in this way, when the connector 29 is not connected, the connection terminal 17 can be more reliably protected from impact or the like.

In the above-described embodiment, the case where the protrusion main body 27 of the protrusion 26 is formed in a substantially cylindrical shape has been described.
