Description

  The present invention relates to a waterproof terminal, and in particular, when an electric circuit portion is waterproofed or when a wiring member outside the electric circuit portion is connected to the electric circuit portion, water can be prevented from entering the electric circuit portion. The present invention relates to a waterproof portable terminal having a waterproof function.

  In recent years, a large number of mobile phones have been developed and used, but in the rainy weather, waterproof mobile phones have been developed that do not soak into the housing even if rainwater adheres to the terminal.

  For example, as a first example, in a portable electronic device, an FPC disposed in a first housing, a second housing, a hinge mechanism, an FPC, and a first insertion portion provided in the first housing. A first seal member that liquid-tightly supports and a second seal member that is disposed in a second insertion portion provided in the second housing and that supports the FPC in a liquid-tight manner. At least one of the two seal members is formed from a part of packing of at least one of the corresponding first casing and second casing, and part of the packing is integrally formed with the FPC by insert molding There is. The housing for storing the packing is formed with a receiving groove and a convex portion at a position facing the groove, and the packing received in the receiving groove is crushed by the receiving groove and the convex portion. .

  As a second example, in an electronic device in which an electrical connection line is connected from the outside of the housing to the inside of the housing, a cylindrical shape is formed at both ends of the through hole provided in the housing and the waterproof tube. A waterproof cap provided with a terminal fixing member, wherein an outer peripheral surface of the tube having an electrical connection line is attached to a wall surface of an inner peripheral portion of the terminal fixing member in a watertight manner, and the outer peripheral portion is an electronic Some have a waterproof cap that can be attached to and detached from a through hole formed in a housing of the device.

  In the electronic apparatus provided with the waterproof cap described as the first example, when the outer peripheral surface of the tube is water-tightly attached to the wall surface of the inner wall portion of the terminal fixing member, the peripheral length of the inner wall portion and the outer periphery of the tube If the perimeters of the are not matched, it is difficult to attach them watertight. For example, when the latter is longer than the former, a gap may be generated between the two. In addition, when the latter is shorter than the former, the tube can be passed through the terminal fixing member by bending a part of the outer periphery of the tube in the radial direction. There is a risk that a gap will occur. Moreover, in order to make the attachment of the wall surface of the inner peripheral part of the terminal fixing member and the outer peripheral surface of the tube heat-welded, if there is a gap between them, the attachment may be insufficient. Therefore, since both require high dimensional accuracy, advanced manufacturing know-how is required. As a result, the yield may be reduced and the cost may be increased.

  Further, in the portable electronic device described as the second example, the packing is disposed around the outer periphery of the first housing or the second housing, but is disposed around a wide range, Since the cross-sectional shape was small or thin, it was easily deformed when handling the packing (poor handling properties). Although details are not clearly shown, a parting line portion is generated when the packing is generated, and burrs are likely to remain in the parting line portion. When the parting line part including the burr is disposed so as to contact the bottom surface or the convex part of the housing groove, a minute gap is generated in the parting line part even if the parting line part is crushed. For this reason, the parting line portion must be assembled so that it does not come into contact with the bottom surface or the convex portion of the receiving groove, resulting in an increase in the number of assembly steps. Alternatively, since it is necessary to remove burrs from the part in order to make the parting line portion in any position, the number of deburring steps and the number of inspection steps are increased.

  Moreover, when applied to a foldable portable electronic device in which two casings are connected so as to be foldable, a plurality of packings are required, resulting in a more expensive component. In addition, there is a demerit that the number of parts manufacturing days becomes longer due to an increase in the number of parts inspection steps.

  Further, in the portable wireless device described as the third example, in order to generate packing around the metal core in the mold, the entire metal core must not be in contact with the mold, but it is practical. Absent. Therefore, although details are not clearly shown, the mold requires a structure for holding a metal core. It is difficult to produce a rubber packing at the part that holds the metal core. Furthermore, in order to produce a rubber packing on the entire metal core, there is a warp in the part other than the part held by the mold. Since no rubber packing is generated at the contacted part, the metal core dimensions, especially warpage, require high precision, and a special mold structure is required. There is a risk of incurring up.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a waterproof terminal that avoids a decrease in yield, does not increase costs, and can avoid an increase in size.

A second dissimilar material member 68 is provided inside, and the second arm portion 75 is in close contact therewith. Moreover, it has the 2nd parting part 76 produced | generated when shape | molding with a metal mold | die.

  Next, a description will be given with reference to FIG. The tube member 31 is guided to the first housing 2 through the second hinge 29. A tubular first cylindrical member 80 is press-fitted inside one end side (first housing 2 side) of the tube member 31, and the tube member 31 forms a first large diameter portion 81. A first gasket 54 is formed around the first large diameter portion 81. The first protrusion 69 of the first gasket 54 is placed on the bottom surface of the first housing groove 60. In FIG. 6, the first gasket 54 has a cross-section of the tube receiving groove 64 that stores the tube insertion portion 63, but the portion other than the tube insertion portion 63 in the first gasket 54 is the same as the second gasket 67. It is a cross section.

  The inner surface of the back surface 2B of the upper housing 2 forms a first facing portion 81 that faces the first housing groove 60, presses the second projecting portion 72, and the first projecting portion 69 and the second projecting portion 70 are respectively provided. It collapses by a predetermined amount. The crushed first gasket 54 applies a reaction force to the first receiving groove 60 and the first facing portion 81.

  The tube member 31 led out from the opposite end of the second hinge 29 is bent a plurality of times in the connecting portion 4 and guided to the second housing 3 side. A tubular second cylindrical member 83 is press-fitted inside the other end side (second housing 3 side) of the tube member 31, and the tube member 31 forms a second large diameter portion 84. A connection member 55 is provided around the second large diameter portion 84. The connection member 55 includes an elastic part 85 and a non-elastic part 86 and has a third through hole 87 inside. The elastic portion 85 is made of a rubber material such as silicon, and a protruding first elastic portion 85a is formed on the inner surface (the third through hole 87 side) of the connecting member 55, and the protruding second elastic portion is formed on the outer periphery of the connecting member. A portion 85b is formed. The non-elastic portion 86 is formed from a resin material such as polycarbonate. When the second large diameter portion 84 is inserted into the third through hole 87 and attached so that the first elastic portion 85a is in close contact with the second large diameter portion 84, the first elastic portion 85a and the tube member 31 are located. Only a fixed amount collapses. The connection member 55 mounted on the second large diameter portion 84 is press-fitted into the second through hole 66. In the press-fitted connection member 55, the second elastic portion 85 b is crushed by a predetermined amount by the inner surface of the second through hole 66.

The connecting member 55 inserted into the second through hole 66 cannot escape from the second through hole 66 when the facing member 88 is attached.

  A tape 89 having a good surface sliding property is appropriately wound around the tube member 31. Since the tube member 31 is made of silicon rubber as described above, the surface of the tube member 31 is worn when rubbed against other members (for example, the inner surface of the connecting member 4). When the main body 1 is opened and closed, the tube member 31 is twisted together with the cable 29 and finely moves. When the tube member 31 that is a rubber material is finely moved while its outer periphery is in contact with the inner surface of the connecting portion 4 or the like, the surface of the tube member 31 is worn. When the amount of wear is large, a hole is generated in the tube member 31, and water may enter through the hole. The water that has entered the tube member 31 adheres to the first printed circuit board 12 disposed inside the first housing groove 60 and the second printed circuit board 18 disposed inside the second housing groove 65. The first printed circuit board 12 and the second printed circuit board 18 may cause a short circuit and cause an abnormal operation when moisture adheres to the surface. Therefore, since the tape 89 is provided on the surface of the tube member 31 in the connecting portion 4, the tube member 31 that rubs against the inner surface of the connecting member 4 is rubbed by the tape 89 having good slidability, thereby avoiding damage to the tube member 31. It can be done.

  The third protrusion 69 is in contact with the bottom surface of the second storage groove 65, and the second different material member 68, the fourth protrusion 74, and the second parting line portion 76 protrude from the second storage groove 65. The second gasket 67 is housed in the second housing groove 65. The inner surface of the lower surface 3 </ b> B of the lower housing 3 forms a second facing portion 89 that faces the second housing groove 65. The second facing portion 89 presses the fourth projecting portion 74, and the third projecting portion 73 and the fourth projecting portion 74 are crushed by a predetermined amount. The crushed second gasket 67 applies a reaction force to the bottom surface of the second accommodation groove 65 and the second facing portion 89.

  When the first gasket 54 and the second gasket 67 are generated, a parting line portion is generated, and burrs are likely to remain in the parting line portion. When the parting line part including burrs is arranged so as to contact the bottom surface of the receiving groove and the facing part facing the receiving groove, even if the burr is crushed, a minute gap is generated in the parting line part. End up. Therefore, it is necessary to assemble the parting line portion so that the parting line portion does not come into contact with the bottom surface or the opposing portion of the housing groove. In the present embodiment, the parting portions 72 and 76 are placed in the respective housing grooves 60 and 65 simply by placing the first gasket 54 and the second gasket 67 in the first and second housing grooves 60 and 65, respectively.

The inner surface of the rear surface 2 </ b> B of the upper housing 2 forms a first facing portion 82 that faces the first housing groove 60. The 1st opposing part 82 presses the 2nd projection part 70, and the 1st projection part 69 and the 2nd projection part 70 are crushed by predetermined amount, respectively. The crushed first gasket 54 applies a reaction force to the bottom surface of the first accommodation groove 60 and the first facing portion 81. The reaction force acts on the bottom surface of the first housing groove 60, the first facing portion 81, the bottom surface of the second housing groove 65, and the second facing portion 89, and water is applied by applying a predetermined pressure. Inundation into the area surrounded by these is prevented.

  When used outdoors in rainy weather, rainwater may infiltrate from the clearances 48A, 48B, 48C in the connecting portion 4. Water that has entered the connecting portion 4 adheres to the surface of the tube member 31, but cannot enter the inside of the tube member 31. Even if the tube member 31 moves to the upper housing 2 side along the surface of the tube member 31, the tube member 31 and the first gasket 54 are in close contact with each other, and the first gasket 54 is in contact with the bottom surface of the first receiving groove 60 and the first gasket. Since they are arranged while being compressed between the facing portions 82, the water that has entered from the clearances 48 </ b> A, 48 </ b> B, 48 </ b> C does not enter the inside of the first accommodation groove 60.

  Even if water moves along the surface of the tube member 31 to the lower housing 3 side, the tube member 31 and the connection member 55 are in close contact with each other. Since it is in close contact with the periphery of the entrance, the water that has entered through the clearances 48A, 48B, and 48C does not enter the inside of the second accommodation groove 65. Since the second gasket 67 is disposed while being compressed between the bottom surface of the second accommodation groove 65 and the second facing portion 89, water does not enter the inside of the second accommodation groove 65.

  That is, a configuration is realized in which rainwater enters from the connecting portion 4 and does not enter inside the first accommodation groove 60 and the second accommodation groove 65.

  In this embodiment, the dissimilar material member is made of a sheet-like polyimide material. However, when the polyimide sheet does not have an antenna function, it may be made of PEN resin or polycarbonate resin. The purpose of providing the dissimilar material member was that the thin gasket had a small cross-sectional shape or was thin, so that it was easily deformed when handled (poor handling properties). For this reason, the dissimilar material member having higher rigidity than the gasket is integrally provided to improve the handling property first. Second, since the gasket is prevented from being twisted (twisted), the first projecting portion and the second projecting portion are always placed in the same posture (state) even when mass-produced. Therefore, a stable reaction force can be generated. Therefore, variation in waterproof resistance can be reduced.

  In the present embodiment, the polyimide material is selected as the dissimilar material member because, at the time of rubber molding, a polyimide material is previously placed in a mold and a molding method in which the rubber material is filled is adopted. The temperature of the rubber material is high. Therefore, a material having heat resistance that does not melt at the set mold temperature or the temperature of the rubber material may be selected.

  Alternatively, even if a gasket made only of a rubber material is formed in advance and different material members are integrated with an adhesive or the like, the effect of improving the handling property is the same.

  In summary, in order to prevent water from entering from outside the range (predetermined range) in which the printed circuit board, receiver, speaker, operation unit, etc. are accommodated, a gasket is provided in the accommodation groove surrounding the predetermined range. When a cable is guided from outside the predetermined range within this predetermined range, the cable passes through a tube member having a large diameter portion that does not bend and deform even when an external force is applied, and protrudes from the large diameter portion or the large diameter portion. Insert the cylindrical member into the gasket. Alternatively, a connection member is provided on the outer periphery of the large-diameter portion, inserted into a through hole that communicates with the inside of the housing groove, and the elastic portion of the connection member is disposed on the outer periphery of the large-diameter portion, and is press-fitted into the through hole provided in the housing groove. Or it is made the structure which press-contacts around the entrance of a through-hole.

  According to this configuration, first, the cylindrical member and the tube member in the large-diameter portion can be closely adhered without a gap. Secondly, since the large-diameter portion, which is not crushed or deformed even when an external force is applied, is connected to the through hole provided in the gasket or the housing groove that accommodates the gasket, intrusion from the connection site can be avoided. It has become. As a result, the inside of the predetermined region and the inside of the tube member can be connected while realizing a configuration that does not flood from the outside. Therefore, even if moisture exists around the tube member, it can be prevented from entering the predetermined range.

  Further, even when an external force is applied to the connecting member, the large diameter portion of the tube member is not deformed. Therefore, the connection member and the through hole and the surface of the connection member and the tube member can be closely adhered without any gap. In addition, since the non-elastic portion is integrated with the connection member, when the connection member is press-fitted into the through hole, only the operation of pushing the non-elastic portion while grasping it is sufficient. If the non-elastic part is a soft elastic part, even if it is pressed, the elastic part only dents and cannot be inserted into the through hole. Therefore, since the inside of the predetermined region and the inside of the tube member can be connected with a simple configuration and operation, even if moisture is present around the tube member, it is possible to prevent intrusion into the predetermined range.

  As a second example of the connecting member, an annular gasket is provided at the large diameter portion, and the gasket is disposed so that the casing is sandwiched and compressed.

  According to this configuration, when an external force is applied to the annular gasket, the inside of the annular gasket is shielded from the outside without a gap. Moreover, even if the force acting on the annular gasket acts on the large-diameter portion, the large-diameter portion is not deformed, so that the annular gasket and the large-diameter portion can be maintained with no gap therebetween. Therefore, since the inside of the annular gasket and the inside of the tube member can be connected with a simple configuration, even if moisture is present around the tube member or outside the annular gasket, it is within a predetermined range (inside the annular gasket). Intrusion can be prevented.

  Further, the gasket is provided with a different material member made of a hard material different from that of the gasket on a side surface in a direction orthogonal to the direction in which the gasket is compressed.

  According to this configuration, since the irregular annular gasket can be shaped (the component aspect, state, and shape do not easily change), the gripping property can be improved. In addition, since the annular gasket is disposed in a direction orthogonal to the compression direction, only the gasket excluding the member made of a different material can be brought into contact with the urging surface that urges the annular gasket. Therefore, since the man-hour for the work of placing the annular gasket in the accommodation groove can be shortened, an increase in cost can be avoided.

  Further, since the tube member that rubs against the inner surface of the connecting member is rubbed with a tape having good slidability, damage to the tube member can be avoided.

  As a result, the opening / closing life characteristics of the main body (performance deterioration due to repeated opening / closing), in particular, the wear resistance characteristics of the tube member are improved.

  In the present embodiment, large diameter portions are formed at both ends of the tube member, and one end portion is inserted through the gasket, thereby connecting the inside of the tube member and the inner region of the gasket. Further, a connecting member is provided at the other end, and the inside of the tube member and the inside of the predetermined area are connected by connecting (inserting) into a through hole communicating with the inside of the predetermined area. In the present embodiment, a plurality of methods for connecting the inside of the tube member and the inside of the predetermined region are described, and the method for connecting one end of the tube member to the predetermined region may be different.

  In the present embodiment, the tube member and the first gasket have been described as being formed as separate bodies, but may be formed integrally. At least when the external force is applied to the first protrusion or the second protrusion, the first cylindrical member is placed in the tube member in order to prevent the hollow first gasket from deforming from a circular shape to a substantially elliptical shape. What is necessary is just to provide.

  In the waterproof portable terminal according to the present embodiment, an annular gasket is provided around the electric circuit portion, and when the wiring member is led from the outside to the inside of the annular gasket, the tube member having the wiring member disposed therein is A cylindrical member is attached to the end portion to form a large-diameter portion, and the large-diameter portion is connected to an annular gasket or an accommodation groove in which the annular gasket is accommodated. With such a configuration, it is possible to reliably prevent water from entering the intrusion prevention unit with a simple structure, and to realize a waterproof portable terminal that is low in cost and has good assembly properties. It has many effects such as low cost and good assembly, and it can be used outdoors such as mobile phones, PDAs, mobile PCs, notebook PCs, etc. It is suitable for application to a waterproof portable terminal in an electronic apparatus having a certain size.

  The waterproof portable terminal according to the present invention has the effects of avoiding a decrease in yield, not incurring an increase in cost, and avoiding an increase in size, and is provided with a cellular phone, a PDA, a mobile PC, a notebook type It is useful as a waterproof portable terminal or the like in an electronic device that may be used outdoors such as a PC or in a bathroom.
