Description

  The present invention relates to an electromagnetic wave shielding gasket for electromagnetically shielding a gap between electronic devices and an electronic device having an electromagnetic wave shielding gasket.

  Conventionally, electromagnetic wave shielding gaskets that electromagnetically shield gaps in electronic devices have been proposed. For example, an insertion portion inserted into a gasket holding hole provided in a first opposing wall constituting a part of a housing of the electronic device main body so as to penetrate from the outer wall surface to the inner wall surface, and abuts on the outer wall surface One having a gasket body and a retaining portion that comes into contact with the inner wall surface is known. The retaining portion includes a leg portion and a foot portion that is coupled to the leg portion and disposed at an acute angle with respect to the leg portion. When the retaining portion is pushed into the gasket retaining hole from the outer wall surface side of the first opposing wall, the foot portion of the retaining portion is elastically deformed, and the width dimension of the foot portion is reduced, and the gasket retaining portion is retained. The insertion portion can be inserted into the gasket holding hole through the hole to the inner wall surface side of the first opposing wall. Further, when the foot part comes out to the inner wall surface side, the elastically deformed foot part is restored and the tip of the foot part comes into contact with the inner wall surface. As a result, the electromagnetic wave shielding gasket can be held in the gasket holding hole, and in this state, the force of the foot portion trying to pull out the gasket holding hole from the inner wall surface side to the outer wall surface side is increased. The foot is not easily elastically deformed because the foot is arranged at an acute angle with respect to the leg, and the foot has a hole for holding the gasket from the inner wall to the outer wall. It is made difficult to come off (see Patent Document 1).

However, in this case, since the retaining portion is composed of the leg portion and the foot portion arranged so as to form an acute angle with the leg portion, the distance from the base portion of the foot portion to the distal end is increased and the retaining portion is prevented. The overall height of the part is high. As a result, the amount of protrusion from the inner wall surface to the inward direction of the housing increases with the foot portion disposed on the inner wall surface side. For this reason, for example, when there is another member such as a member to be stored housed in the housing near the inner wall surface of the electronic device, when the foot is passed through the gasket holding hole from the outer wall surface side, There is a case where it is difficult to place the foot part on the inner wall surface side by hitting the other, and it is difficult to hold the electromagnetic shielding gasket in the gasket holding hole. Therefore, the electromagnetic shielding gasket that passes the retaining portion as described above from the outer wall surface through the gasket holding hole is applicable to an electronic device in which there are other members such as housing members near the inner wall surface of the housing. It is hard to do.

It is characterized by being configured to maintain a state larger than the width dimension of the service hole.

  An electronic device having an electromagnetic shielding gasket according to the present invention is an electronic device having an electromagnetic shielding gasket provided with the above electromagnetic shielding gasket and an electronic device main body, and the retaining portion of the electromagnetic shielding gasket is The width dimension from the projecting tip of the first projecting piece to the projecting tip of the second projecting piece is configured to be smaller than the width dimension of the gasket body, and the first opposing wall of the electronic device body is used for holding the gasket. A gasket introduction hole is further provided in communication with the hole for introducing the insertion portion of the gasket for electromagnetic shielding into the gasket holding hole. The width of the gasket introduction hole is the width of the gasket body of the electromagnetic shielding gasket. And the width dimension of the retaining portion of the electromagnetic shielding gasket is substantially the same or Characterized in that it is one that is configured larger than that.

  The features of the present invention can be broadly shown as described above, but the configuration and contents thereof, together with the objects and features, will be further clarified by the following disclosure in view of the drawings.

  The electromagnetic wave shielding gasket according to the first invention of the present application includes an insertion portion that is inserted into the gasket holding hole so as to slide from the longitudinal end portion side of the gasket holding hole, and the retaining portion is inserted A first projecting piece projecting in the width direction of the insertion portion from a first end surface in the width direction of the insertion portion, and a second projecting piece projecting in the width direction of the insertion portion from the second end surface in the width direction of the insertion portion, The one projecting piece and the second projecting piece are at least one of a first distance from the second end surface to the projecting tip of the first projecting piece and a second distance from the first end surface to the projecting tip of the second projecting piece. Even when the first projecting piece or the second projecting piece is deformed by receiving an external force, it is configured to be maintained in a state larger than the width dimension of the gasket holding hole.

  As a result, the retaining portion can be prevented from slipping the gasket holding hole from the inner wall surface side to the outer wall surface side of the first opposing wall, and the electromagnetic shielding gasket can be maintained in the state of being held in the gasket holding hole. .

  Further, the retaining portion can be made unnecessary to be composed of a leg portion and a foot portion arranged so as to form an acute angle with the leg portion as in the conventional case in which the gasket retaining hole is inserted from the outer wall surface side. The overall height of the stopper can be reduced. Thereby, the protrusion amount of the retaining part inward from the inner wall surface of the first opposing wall can be reduced. Therefore, for example, even when there is something in the vicinity of the inner wall surface of the first opposing wall, there is a possibility that the retaining portion may hit the other object when the insertion portion is inserted into the gasket holding hole. The number can be reduced, and the operation of holding in the gasket holding hole can be facilitated. Therefore, it can be made suitable for an electronic device in which there is another in the vicinity of the inner wall surface of the first opposing wall.

  In the electromagnetic wave shielding gasket according to the second invention of the present application, the gasket body is composed of one elongated shape, and the retaining portion and the insertion portion are arranged in the longitudinal direction of the gasket body with a plurality of intervals. It is composed of things.

  Thereby, the resistance when sliding the insertion portion into the gasket holding hole can be reduced, and the operation of holding the insertion portion in the gasket holding hole can be facilitated.

  In the electronic device having the electromagnetic shielding gasket according to the third invention of the present application, the retaining portion of the electromagnetic shielding gasket has a width dimension from the projecting tip of the first projecting piece to the projecting tip of the second projecting piece. The first opposing wall of the electronic device main body is connected to the gasket holding hole and has a gasket introduction hole for introducing the electromagnetic shielding gasket insertion portion into the gasket holding hole. The gasket introduction hole has a width smaller than that of the gasket body of the electromagnetic shielding gasket and is substantially the same as or larger than the width of the retaining portion of the electromagnetic shielding gasket. It is composed largely.

  Thereby, the retaining portion and the insertion portion can be inserted into the gasket introduction hole from the outer wall surface side. And the retaining part can be arrange | positioned to the inner wall surface side of a 1st opposing wall in the state put. Therefore, from this state, for example, by moving the electromagnetic shielding gasket in the direction of the gasket holding hole, it can be easily inserted into the gasket holding hole by sliding the insertion portion. Can be held in the gasket holding hole.

  On the other hand, after the electromagnetic wave shielding gasket is held in the gasket holding hole, the gasket main body can cover the gasket introducing hole so that the electromagnetic wave does not leak from the gasket introducing hole.

  In the electronic apparatus having the electromagnetic shielding gasket according to the fourth invention of the present application, the gasket main body of the electromagnetic shielding gasket is composed of one long one, and the retaining portion and the insertion portion of the electromagnetic shielding gasket are: The gasket holding hole of the electronic device main body is composed of a plurality of parts arranged at intervals in the longitudinal direction of the gasket body, and the plurality of holes arranged at positions corresponding to the retaining portions and insertion portions of the electromagnetic shielding gasket The gasket introduction hole is composed of a plurality of holes provided corresponding to the gasket holding holes.

And the retaining part can be arrange | positioned to the inner wall surface side of a 1st opposing wall, respectively, in the put state. Therefore, from this state, for example, by moving the electromagnetic shielding gasket in the direction of the gasket holding hole, the insertion portions can be inserted into the gasket holding holes, respectively. At that time, it is only necessary to slide the length of the insertion portion, and the operation of inserting the insertion portion into the gasket holding hole can be facilitated.

  That is, first, after inserting the corresponding retaining portion and insertion portion into the gasket introduction hole communicating with the first end of the gasket holding hole, the electromagnetic shielding gasket is moved in the direction of the gasket holding hole. These insertion portions are simultaneously inserted into the corresponding gasket holding holes. Next, by bending (or extending) the electromagnetic shielding gasket from the normal state, a corresponding retaining portion and insertion portion were inserted into the gasket introduction hole communicating with the second end of the gasket holding hole. Then, by returning the electromagnetic shielding gasket to the normal state, the insertion portion is inserted into the corresponding gasket holding hole.

  Since each insertion portion inserted in this manner does not come out of the gasket holding hole unless the electromagnetic shielding gasket is bent (or expanded), it can be surely coupled to the electronic device. Moreover, even if the dimensional accuracy of the gasket holding hole is low, the insertion portion does not come off from the gasket holding hole, which is advantageous.

  Further, when the top portion 21a is subsequently pressed against the side wall 102d, the top portion 21a is maintained in a state of being pressed against the rear side wall 102d by the elasticity of the elastic member 22. Therefore, in this state, the adjacent casings 102 and 102 can be reliably brought into conduction via the connecting member 21 of the electromagnetic wave shielding gasket 1, and the gap 109 between both can be electromagnetically shielded.

  Further, as shown in FIG. 11, for example, a force is applied to the electromagnetic shielding gasket 1 so that the insertion portion 4 pulls the gasket holding hole 104 from the inner wall surface 102c side to the outer wall surface 102b side of the front side wall 102a. Even when both or one of the projecting piece 31 and the second projecting piece 32 is deformed by receiving a reaction force from the inner wall surface 102c of the front side wall 102a, the first distance L1 and the second distance L2 hold the gasket. The state where it is larger than the width dimension V1 of the hole 104 is maintained.

  Therefore, the insertion portion 4 can prevent the gasket holding hole 104 from slipping out from the inner wall surface 102c side to the outer wall surface 102b side of the front side wall 102a.

  Next, a communication device 200 having an electromagnetic shielding gasket as a communication device having an electromagnetic shielding gasket according to another embodiment of the present invention will be described.

  The communication device 200 is different from the communication device 100 described above in the following points. That is, in the communication device 100, as shown in FIG. 1, the communication direction of the gasket holding hole 104 provided in the front side wall 102a and the gasket introduction hole 105 communicating therewith is such that all the gasket holding holes 104 and The gasket introduction holes 105 are in the same direction (in FIG. 1, all of the gasket introduction holes 105 communicate with the upper end of the gasket holding hole 104). That is, as shown in FIG. 5, all the gasket introduction holes 105 are communicated with the first ends 104 a in the longitudinal direction of the corresponding gasket holding holes 104.

  However, in the communication apparatus 200 according to the present embodiment, some of the gasket introduction holes 105 among the plurality of gasket introduction holes are communicated with the first end 104a in the longitudinal direction of the gasket holding hole 104, and the remaining gaskets. The introduction hole 205 is configured to communicate with the second end 104 b in the direction opposite to the first end 104 a in the longitudinal direction of the gasket holding hole 104. The electromagnetic shielding gasket 1 is configured to have flexibility using, for example, a synthetic resin. The remaining configuration of the communication device 200 is the same as that of the communication device 100.

  An example of the communication device 200 is shown in FIGS. 12A and 12B. 12A is a plan view of an appropriate portion of the front side wall 102a of the communication device 200, and FIG. 12B shows a cross section XIIB-XIIB in FIG. 12A.

  In this example, for convenience of explanation, it is assumed that four gasket holding holes 104 and four gasket introduction holes communicating with the four gasket holding holes 104 are arranged at appropriate portions of the front side wall 102a of the communication device 200. The four gasket holding holes 104 are arranged at an equal pitch in the horizontal direction of the drawing.

  Of the four gasket introduction holes, three (gasket introduction holes 105) on the left side of the drawing communicate with the first ends 104a of the corresponding gasket holding holes 104, respectively. On the other hand, the one at the right end of the drawing (the gasket introduction hole 205) communicates with the second end 104b of the corresponding gasket holding hole 104.

  13A and 13B are diagrams for explaining a procedure for mounting the electromagnetic wave shielding gasket 1 on the front side wall 102a of the communication device 200. FIG. In order to attach the electromagnetic shielding gasket 1 to the front side wall 102a, first, the corresponding three retaining portions 3 and the insertion portions 4 of the electromagnetic shielding gasket 1 are inserted into the three gasket introduction holes 105 shown in FIG. The paper is inserted from the front side in FIG. 12A toward the other side. This state is the same as the state shown in FIGS. 6 and 7 in the above-described embodiment.

  Next, from this state, the electromagnetic shielding gasket 1 is slid in the left direction in FIG. 12A (downward in FIG. 6 and FIG. 7). The state after sliding is the same as the state shown in FIGS. 8 and 9 in the above-described embodiment. Accordingly, the three insertion portions 4 are simultaneously inserted into the corresponding gasket holding holes 104, respectively.

  Next, from this state, while bending the vicinity of the right end of the gasket body 2 of the electromagnetic wave shielding gasket 1, the right end gasket introduction hole 205 shown in FIG. The insertion portion 4 is inserted from the front side of the sheet of FIG. 12A toward the other side. This state is shown in FIG. 13A.

  Next, by releasing the bent electromagnetic shielding gasket 1 from this state, the electromagnetic shielding gasket returns to the normal state as shown in FIG. 13B. As a result, the right insertion portion 4 of the electromagnetic shielding gasket 1 is inserted into the gasket holding hole 104 at the right end. In this manner, the electromagnetic wave shielding gasket 1 is attached to the front side wall 102a of the communication device 200.

  In this manner, each inserted portion 4 inserted does not come off from the gasket holding hole 104 unless the electromagnetic shielding gasket 1 is bent, so that the electromagnetic shielding gasket 1 is securely attached to the front side wall 102a of the communication device 200. Can be combined. On the other hand, in order to remove the electromagnetic shielding gasket 1 from the front side wall 102a, it can be easily removed by executing a procedure reverse to that at the time of attachment.

  Moreover, in this embodiment, the return prevention part 107 (refer FIG. 5) in the above-mentioned embodiment is not provided in the front side wall 102a. Although the return preventing portion 107 may be provided, the electromagnetic wave shielding gasket 1 can be securely coupled to the front side wall 102a without being provided, and an obstacle in removing the electromagnetic wave shielding gasket 1 from the front side wall 102a. In order to avoid this, it is preferable not to provide the return prevention portion 107. By not providing the return preventing portion 107 that requires high dimensional accuracy, the front side wall 102a can be manufactured at a lower cost.

  Next, FIG. 14A shows a plan view of an appropriate portion of the front side wall 102a according to another example of this embodiment. In this example, unlike the example shown in FIG. 12A, of the four gasket introduction holes, the two on the left side of the drawing (gasket introduction hole 105) are the first ends 104a of the corresponding gasket holding holes 104, respectively. Communicating with On the other hand, the two on the right side of the drawing (the gasket introduction hole 205) communicate with the second end 104b of the corresponding gasket holding hole 104, respectively.

  Next, FIG. 14B shows a plan view of an appropriate portion of the front side wall 102a according to still another example in this embodiment. In this example, of the two gasket introduction holes, the one at the left end of the drawing (the gasket introduction hole 105) communicates with the first end 104a of the corresponding gasket holding hole 104. On the other hand, the one at the right end of the drawing (the gasket introduction hole 205) communicates with the second end 104b of the corresponding gasket holding hole 104.

  Thus, when using the electromagnetic wave shielding gasket 1 having flexibility, as shown in FIGS. 12A to 14B, a plurality of sets (four sets in FIGS. 12A to 14A and two sets in FIG. 14B) Of the corresponding gasket holding holes 104 and the gasket introduction holes, the gasket introduction holes 105 and 205 of two adjacent sets of “corresponding gasket holding holes 104 and gasket introduction holes” are adjacent to each other. What is necessary is just to comprise.

  Next, FIGS. 15A to 15C are respectively plan views of appropriate portions of the front side wall 102a according to still another example of this embodiment. These front side walls 102a are applied when the electromagnetic shielding gasket 1 having elastic extensibility is used.

  That is, in this case, as shown in FIGS. 15A to 15C, among a plurality of sets (four sets in FIGS. 15A to 15B and two sets in FIG. 15C) of “corresponding gasket holding holes 104 and gasket introduction holes” The gasket holding holes 104 of two adjacent sets of “corresponding gasket holding holes 104 and gasket introduction holes” may be adjacent to each other.

  In the example shown in FIGS. 15A to 15C, the procedure for attaching the electromagnetic shielding gasket 1 to the front side wall 102a is performed by flexing the electromagnetic shielding gasket 1 in the example shown in FIGS. 12A to 14B and releasing it. Instead of returning to the normal state, the electromagnetic shielding gasket 1 may be elastically stretched and then released to return to the normal state.

  In each of the above-described embodiments, the electromagnetic shielding gasket 1 includes one gasket body 2, a plurality of insertion portions 4, and a plurality of retaining portions 3. Although a plurality of gasket holding holes 104 provided at positions corresponding to the insertion portion 4 and the retaining portion 3 are provided, the present invention is not limited to this configuration and can be changed as appropriate.

  For example, the electromagnetic shielding gasket 1 is composed of one gasket body 2, a plurality of insertion portions 4, and a plurality of retaining portions 3, while the gasket holding hole 104 of the apparatus body 101 is connected to the gasket body 2. It consists of one having approximately the same length. Alternatively, the electromagnetic shielding gasket 1 includes one gasket body 2, one insertion portion 4 having substantially the same length as the gasket body 2, and one retaining portion 3 having substantially the same length as the insertion portion 4. The gasket holding hole 104 may be formed of a single piece having substantially the same length as the gasket main body 2.

  Further, when the insertion portion 4 and the retaining portion 3 of the electromagnetic wave shielding gasket 1 are composed of a plurality of members, the numbers of the inserting portions 4 and the retaining portions 3 are not particularly limited and can be appropriately changed.

  In the first embodiment, the guide portions 106 and 106 and the return prevention portions 107 and 107 are provided between the gasket holding hole 104 and the gasket introduction hole 105. However, it can be changed as appropriate.

  For example, either one of the guide portions 106 and 106 and the return prevention portions 107 and 107 may be provided between the gasket holding hole 104 and the gasket introduction hole 105, or both may not be provided. .

  In the second embodiment, the guide portions 106 and 106 are provided between the gasket holding hole 104 and the gasket introduction holes 105 and 205. However, the present invention is not limited to this configuration. Can be changed.

  For example, both the guide portions 106 and 106 and the return prevention portions 107 and 107 may be provided between the gasket holding hole 104 and the gasket introduction holes 105 and 205, or both may be omitted.

  Moreover, it can also be comprised so that the presence or absence of the guide parts 106 and 106 and / or the return prevention parts 107 and 107 may differ in one and the other of the gasket introduction holes 105 and 205.

  For example, the guide portions 106 and 106 may be provided for all the gasket introduction holes 105 and 205, and the return prevention portions 107 and 107 may be provided only for the gasket introduction holes 205.

  Further, in each of the above embodiments, the presence / absence of the guide portions 106 and 106 and / or the return prevention portions 107 and 107 is determined depending on whether the plurality of gasket holding holes 104 are arranged at the end or in the middle. Can be configured to be different.

  For example, the guide portions 106 and 106 are provided for all the gasket holding holes 104, and the return preventing portions 107 and 107 are provided only for the gasket holding holes 104 arranged at one end (or both ends). be able to.

  In each of the above embodiments, the gasket introduction hole 105 (205) is provided. However, the gasket introduction hole 105 (205) may not be provided. For example, the gasket holding hole 104 has an opening at the first end, and the electromagnetic shielding gasket 1 is inserted into the gasket holding hole 104 while sliding from the opening. The first end may close the opening of the gasket holding hole 104.

  Further, in each of the above embodiments, the insertion portion 4 and the retaining portion 3 are configured with substantially the same vertical dimension (longitudinal dimension), but can also be implemented with different vertical dimensions. Can be changed as appropriate.

  Further, in each of the above embodiments, the width dimension V2 of the gasket introduction hole 105 (205) is set to the width dimension V5 of the retaining portion 3 of the electromagnetic wave shielding gasket 1 in a normal state (non-load state where no external force is received). However, the width dimension V2 of the gasket introduction hole 105 (205) is such that the retaining portion 3 can enter the gasket introduction hole 105 (205) from the outer wall surface 102b side. good.

  For example, even if the width dimension V2 of the gasket introduction hole 105 (, 205) is the same as or smaller than the width dimension V5 of the retaining portion 3 of the electromagnetic wave shielding gasket 1 in the normal state, the retaining portion 3 remains the gasket introducing hole. 105 (205), the first protruding piece 31 and / or the second protruding piece 32 of the retaining portion 3 are deformed by receiving a reaction force from the outer wall surface 102b by being pushed in from the outer wall surface 102b side. The width dimension V2 of the gasket introduction hole 105 (205) is larger than the width dimension V5 of the retaining part 3 in the deformed state, and the retaining part 3 is connected to the gasket introduction hole 105 (205). The thing of the dimension which can enter from the 102b side may be sufficient. Further, the dimensions V2 and V5 may be set so as to be able to enter the gasket introduction hole 105 (205) while the retaining portion 3 is inclined.

  In each of the above embodiments, the gasket holding hole 104 is provided in the front side wall 102a as the first opposing wall in the housing 102 of the communication device 100 (or the communication device 200) as an electronic device, and the electromagnetic shielding gasket. 1 is configured to electromagnetically shield the gap 109 between the casing 102 and the adjacent casing 102 by being held in the gasket holding hole 104 of the front side wall 102a. It can change suitably not only in the thing.

  For example, the upper wall or the lower wall of the housing 102 of the communication device 100 (or the communication device 200) is used as the first opposing wall, and the gasket 1 for holding the electromagnetic wave shield is held by providing a gasket holding hole 104 on the upper or lower wall. Let And the casing 101a of the communication apparatus 100 (or communication apparatus 200) facing the upper side wall or the lower side wall is used as the second opposing wall, and the gap between the casing 101a and the upper side wall or the lower side wall is defined by the electromagnetic wave shielding gasket 1. You may make it shield electromagnetically.

  The electronic device of the present invention is not limited to the communication device 100 (or the communication device 200) but can be changed as appropriate, and can be applied to various devices that generate electromagnetic waves.

  Next, a communication device 300 having an electromagnetic shielding gasket as a communication device having an electromagnetic shielding gasket according to still another embodiment of the present invention will be described.

  The communication device 300 differs from the above-described communication device 200 in the following points. That is, in the communication device 200, as shown in FIGS. 12A and 13A, a plurality of gasket holding holes 104 communicating with the gasket introduction hole 105 at the first end 104a in the longitudinal direction of the gasket holding hole 104 (in the drawings). Are provided on the left side, but the intervals between the first ends 104a of the gasket holding holes 104 are all equal, and the insertion direction end of the corresponding insertion portion 4 of the electromagnetic shielding gasket 1 (drawing). The left end) is the same as the interval between each other.

  On the other hand, also in the communication apparatus 300 according to the present embodiment, a plurality of gasket holding holes 104 are communicated with the gasket introduction hole 105 at the first end 104a in the longitudinal direction of the gasket holding hole 104 (three in the drawing). As shown in FIG. 16A, in the present embodiment, at least one of the intervals R1, R2 between the first ends 104a of the gasket holding hole 104 corresponds to the electromagnetic shielding gasket 1 as shown in FIG. 16A. The insertion portion 4 is configured to have an interval different from the intervals P1 and P2 between the ends in the insertion direction (referred to as a reference position 4a; the left end in the drawing).

  Specifically, in this example, R1 = R2 <P1 = P2. In this example, the longitudinal dimension (corresponding to W4 in FIG. 2) Q1, Q2, and Q3 of the insertion portion 4 of the electromagnetic wave shielding gasket 1 is configured such that Q1 = Q2 = Q3.

  The longitudinal dimension T1, T2, T3 (corresponding to the longitudinal dimension W1 in FIG. 5) of the gasket holding hole 104 is configured to satisfy T1> T2> T3. In this example, the return prevention portion 107 shown in FIG. 5 is not provided on the front side wall 102a. In this example, T2 = Q2.

  The total dimensions U1, U2, and U3 of the longitudinal dimension of the gasket introduction hole 105 (corresponding to the longitudinal dimension W2 in FIG. 5) and the insertion direction dimension of the guide portion 106 (dimension in the X1 direction in FIG. 16A) are U1 <U2 <. It is configured to be U3. Further, the configuration is such that Q1 <U1.

  The total dimensions T1 + U1, T2 + U2, and T3 + U3 of the longitudinal dimension T1, T2, T3 of the gasket holding hole 104 and the above U1, U2, U3 are configured such that (T1 + U1) = (T2 + U2) = (T3 + U3) Yes. The intervals S1 and S2 between the longitudinal ends (X2 direction ends in the drawing) of the gasket introduction hole 105 on the side not communicating with the gasket holding hole 104 are S1 = P1 and S2 = P2 (and in this example, , S1 = S2).

  The remaining configuration of the communication device 300 is the same as that of the communication device 200.

  Next, a procedure for mounting the electromagnetic shielding gasket 1 on the front side wall 102a of the communication device 300 will be described with reference to FIGS. 16A and 16B. The procedure for attaching the electromagnetic wave shielding gasket 1 to the front side wall 102a is almost the same as that of the communication device 200.

  That is, the corresponding three retaining portions 3 (not shown) and the insertion portion 4 of the electromagnetic wave shielding gasket 1 are inserted into the three gasket introduction holes 105 shown in FIG. 16A from the front side of FIG. After being inserted, the electromagnetic shielding gasket 1 is slid in the X1 direction (left direction) in FIG. 16A to obtain the state of FIG. 16B.

  As described above, in the communication device 300, the intervals R1 and R2 (R1 = R2) between the first ends 104a of the gasket holding holes 104 are all the reference positions of the corresponding insertion portions 4 of the electromagnetic wave shielding gasket 1. 4a is configured to be smaller than the intervals P1 and P2 (P1 = P2).

  Therefore, when the electromagnetic shielding gasket 1 is slid in the X1 direction from the state shown in FIG. 16A, the three reference positions 4a are first the reference position 4a of the leftmost insertion section 4, and then the reference position 4a of the central insertion section 4. , And finally passes through the first end 104a of the corresponding gasket holding hole 104 at different timings in the order of the reference position 4a of the insertion portion 4 at the right end.

  For this reason, the reference position 4a of the insertion portion 4 of the electromagnetic wave shielding gasket 1 is changed from the gasket introduction hole 105 having a wide width (V2, see FIG. 5) to the gasket holding hole 104 having a narrow width (V1, see FIG. 5). The generation timing of the frictional resistance force by the guide unit 106 when being guided can be dispersed.

  As a result, the electromagnetic shielding gasket 1 can be attached to the front side wall 102a of the communication device 300 without applying a large sliding force.

  Thereafter, the right end insertion portion 4 (not shown) is inserted into the gasket introduction hole 205 (not shown) while the vicinity of the right end (not shown) of the gasket body 2 of the electromagnetic wave shielding gasket 1 is bent. The procedure for inserting the right end insertion portion 4 (not shown) into the right end gasket holding hole 104 (not shown) by releasing is similar to that of the communication device 200 (see FIGS. 13A and 13B). It is.

  In addition, each dimension shown to FIG. 16A is not specifically limited. For example, in this example, R1 = R2 <P1 = P2, but R1 <P1 = P2 = R2.

  Moreover, it can apply to the communication apparatus 300 except the thing which cannot be applied to the communication apparatus 300 among all the variations in the above-mentioned communication apparatus 200. FIG.

  Moreover, although this embodiment (communication apparatus 300) showed the application example based on the communication apparatus 200, it is not limited to this. This embodiment (communication device 300) can also be applied based on the communication device 100 described above. In this case, it is possible to apply to the communication device 300 except for all variations in the communication device 100 that are not applicable to the communication device 300.

  Although the present invention has been described above as a preferred embodiment, the terminology has been used for description rather than limitation and departs from the scope and spirit of the present invention. Without departing from the scope of the appended claims. Also, while the above describes only some exemplary embodiments of the present invention in detail, those skilled in the art will recognize the exemplary implementations described above without departing from the novel teachings and advantages of the present invention.
