Description

The present invention relates to a fixed structure of a clip attached to a portable electronic device such as a portable wireless communication device, particularly a reinforced clip for the portable electronic device suitable for police, fire, mountain rescue, and the like.

Since portable electronic devices such as portable wireless communication devices are sometimes used by being worn on a belt or collar, a clip is provided as an option. Since a display panel, operation buttons, a speaker, a microphone, and the like are arranged on the front surface of the wireless communication device, this clip is usually formed of a resin such as polycarbonate and attached to the back side of the wireless communication device. Further, in a portable wireless communication device, it is recommended to use a detachable dedicated secondary battery pack in order to reduce the size of the device, the life of the battery, and the running cost. Therefore, the clip is attached not to the main body of the wireless communication device but to the detachable battery pack side.

In addition, portable wireless communication devices are widely used in fields such as police, fire fighting, and rescue, but in such a life-threatening situation, it is said that the wireless communication device should never fall. Clips have been proposed that are exceptionally sturdy and have strong springs that won't come off easily once installed. FIG. 6 shows the structure of a reinforced clip for a conventional portable electronic device described in Patent Document 1. In FIG. 6, the portable electronic device 100 is composed of a portable electronic device main body 110 and a secondary battery pack 120 mounted on the back side of the portable electronic device main body 110, and the reinforced clip 130 is a secondary battery pack. It is fixed to the back surface 120B of 120 with a screw 140. The reinforced clip 130 has a base 131 fixed to the back surface 120B of the secondary battery pack 120, a hook 132 rotatably supported by the base 131, and a tip 132A of the hook 132 of the secondary battery pack 120. It is composed of a spring 133 or the like that urges the hook 132 so as to press it against the back surface 120B side. The base 131 and the hook 132 are formed of a metal plate such as stainless steel, and the spring 133 is also formed of a metal wire for a spring such as stainless steel so as not to be deformed or damaged even if an impact is applied. Has sufficient strength. Further, the spring 133 is also formed so as to exert a sufficient tightening force so that the tip 132A of the hook 132 does not open even if an impact is applied. At both ends of the base 131 in the width direction (Y direction), two through holes 131A through which the screw 140 penetrates are formed in the middle of the longitudinal direction (X direction) and slightly from the upper end. Further, at the central portion in the width direction of the base 131, at the lower end, a hook-shaped engaging hook 131B that is engaged with the secondary battery pack 120 is formed.

The portable electronic device main body 110 and the secondary battery pack 120 are made of a resin such as polycarbonate, and have sufficient strength to withstand an impact. On the back surface 120B of the secondary battery pack 120, a nut 121 to which the screw 140 is tightened is embedded by insert molding on the upper end 120A side of the back surface 120B of the secondary battery pack 120. Further, at the lower end of the secondary battery pack 120, at the central portion in the width direction, an engaging recess 122 that engages with the engaging hook 131B of the base 131 is formed. To fix the reinforced clip 130 to the secondary battery pack 120, the engaging hook 131B of the base 131 is engaged with the engaging recess 122 of the secondary battery pack 120, and the screw 140 is passed through the through hole 131A. This is done by firmly tightening the nut 121.

Normally, when the reinforced clip 130 is fixed to the secondary battery pack 120, it is not removed until the secondary battery of the secondary battery pack 120 deteriorates and the secondary battery pack 120 needs to be replaced. The next battery pack 120 is charged with the reinforced clip 130 fixed. Therefore, the charger (not shown) is formed with a relief that matches the shape of the reinforced clip 130, and the charging terminal 123 of the secondary battery pack 120 is also positioned to avoid interference with the base 131 of the reinforced clip 130. It is provided.

Japanese Patent No. 4178093

Regarding the secondary battery pack and its charger, in addition to the terminals directly connected to the + and-terminals of the secondary battery, the voltage between the terminals of the secondary electrons can be measured, and it is built into the secondary battery pack. Terminals for writing and reading various information such as the number of times of charging are provided in the existing memory, and the number of charging terminals tends to increase as the function of the secondary battery pack improves. Further, when charging the secondary battery pack while it is placed on the charger without using a connector or the like, it is desirable that the charging terminals are arranged in a row near the lower end of the secondary battery pack. Then, since the base 131 of the reinforced clip 130 is formed of a metal plate as described above, in order to prevent a short circuit between the charging terminals by the base 131, the position of the engaging hook 131B of the base 131 is obtained.

Further, in the conventional fixed structure of the secondary battery pack 120 and the reinforced clip 130, two nuts 121 are embedded in the upper end 120A side of the back surface 120B of the secondary battery pack 120 by insert molding. , It is made of metal such as stainless steel or brass, and a large number of knurled grooves are formed on the outer peripheral portion thereof so that the resin flows during insert molding. The nut 121 is relatively expensive as a component unit price, and is a cause of hindering the cost reduction of the secondary battery pack 120 as well as the price of the mold for insert molding. Further, when the screw 140 is tightened to the nut 121, a certain thickness of the resin must be secured in order to prevent the resin from cracking, so that the insert position of the nut 121 is limited, and the design of the secondary battery pack 120 is designed. It is a cause of reducing the degree of freedom.

The present invention has been made to solve the above problems, and is used for a new portable electronic device for fixing a reinforced clip to a secondary battery pack in which a plurality of charging terminals are arranged near the lower end of the back surface.

Unlike the conventional secondary battery pack 120 shown in FIG. 6, the metal nut is not insert-molded on the back surface 20B of the secondary battery pack 20, and the reinforced clip 40 is attached to the back surface of the secondary battery pack 20. Cannot be fixed directly to the screw. Therefore, in the fixed structure of the reinforced clip of the portable electronic device according to the present embodiment, a clip mounting base member 50 to be fitted to the clip mounting portion 25 formed on the back surface 20B of the secondary battery pack 20 is prepared. A metal nut 51 such as stainless steel or brass is insert-molded into the clip mounting base member 50. The nut 51 is a central portion in the width direction of the clip mounting base member 50, and is provided only at one location substantially in the central portion in the vertical direction. The clip mounting base member 50 is fitted with two guide rails 25A of the clip mounting portion 25, respectively, corresponding to the shape of the clip mounting portion 25, and a pair of flanges 52 protruding from both sides in the width direction thereof. The engaging recess 53 having a trapezoidal cross section engaged with the engaging convex portion 25B is provided, and the nut 51 is provided on the ceiling portion of the engaging recess 53. Further, on the back side of the clip mounting base member 50, in the vicinity of the nut 51, a locking claw 54 that is locked in the rectangular locking hole 41D formed in the base 41 of the reinforced clip 40 is formed. ing. Of the locking claws 54, the lower end 20E side of the secondary battery pack 20 is an inclined surface, and the upper end 20A side is a substantially vertical surface.

Further, the secondary battery pack 20 is provided with a pair of guide grooves 26 formed on both side surfaces 20D thereof, having a predetermined length from the lower end 20E, and having the upper end as a stopper 26A, in addition to the clip mounting portion 25. There is. On the other hand, the base 41 of the reinforced clip 40 protrudes outward in the width direction (Y direction) from the vicinity of the lower end 41A of the base 41, and has a substantially C shape in a cross section perpendicular to the back surface 20B of the secondary battery pack 20. The pair of engaging claws 44 and the pair of engaging claws 44 are engaged with the pair of guide grooves 26 and are fitted into the pair of guide grooves 26 on the side surface 20D of the secondary battery pack 20. A circular penetration formed at a position facing the nut 51 of the clip mounting base member 50 fitted to the clip mounting portion 25 of the secondary battery pack 20 in a state of being in contact with the stopper 26A at the upper end of the guide groove 26. It includes a hole 41C and a fixed portion 41B having a substantially rectangular locking hole 41D formed in the vicinity of the through hole 41C. In the pair of engaging claws 44 of the base 41, the claws 44A engaged with the pair of guide grooves 26 on the side surface 20D of the secondary battery pack 20 are substantially perpendicular to the side surface 20D of the secondary battery pack 20.

The screw 60 is a dedicated decorative screw made of, for example, stainless steel, and the diameter of the head is twice or more the nominal diameter. As described above, since a very large force or acceleration may be applied to the reinforced clip 40, it is necessary to prevent the reinforced clip 40 from falling off due to the breakage of the screw. Therefore, the head of the screw 60 It is preferable to widen the contact area of the portion to disperse the force applied to the screw 60. Further, a through hole 42B for screw tightening having a diameter larger than the diameter of the head of the screw 60 is provided at a position of the hook 42 facing the fixed portion 41B of the base 41.

Next, a procedure for fixing the reinforced clip 40 to the back surface 20B of the secondary battery pack 20 will be described. As can be seen from FIG. 3, when the secondary battery pack 20 is mounted on the portable electronic device main body 10, the clip mounting base member 50 cannot be mounted on the clip mounting portion 25 on the back surface 20B of the secondary battery pack 20. Therefore, as shown in FIG. 4, the secondary battery pack 20 is temporarily removed from the portable electronic device main body 10. Next, the clip mounting base member 50 is fitted into the clip mounting portion 25 from the vicinity of the upper end of the back surface 20B of the secondary battery pack 20 substantially parallel to the back surface 20B. Further, the claw 44A of the engaging claw portion 44 of the base 41 of the reinforced clip 40 is inserted into the guide groove 26 from the lower end 20E of the secondary battery pack 20 and slid along the guide groove 26. Since the lower end 20E side of the locking claw 54 of the clip mounting base member 50 is an inclined surface, the front surface 41E of the fixed portion 41B of the base 41 slides along this inclined surface. When the claw 44A of the engaging claw portion 44 of the base 41 comes into contact with the stopper 26A at the upper end of the guide groove 26, the locking claw 54 fits into the locking hole 41D of the base 41, and at the same time, the base 41 is covered. Since the through hole 41C of the fixing portion 41B faces the nut 51 of the clip mounting base member 50, it is attracted and held by a magnet or the like from the through hole 42B of the hook 42 to the tip bit portion of the screwdriver (not shown). Insert the screwdriver 60 and tighten it to the nut 51. As a result, the reinforced clip 40 is secondary at three points due to the engagement of the fixed portion 41B tightened by the screw 60 and the nut 51, the pair of engaging claw portions 44 of the base 41, and the pair of guide grooves 26. It is fixed to the back surface 20B of the battery pack 20. Even if a tensile force is applied upward in the longitudinal direction (X direction) to the reinforced clip 40, the claw 44A of the engaging claw portion 44 of the base 41 and the stopper 26A at the upper end of the guide groove 26 come into contact with each other to strengthen the clip 40. The mold clip 40 cannot be easily removed from the back surface 20B of the secondary battery pack 20. Further, since the upper end 20A side of the locking claw 54 of the clip mounting base member 50 is a vertical surface, even if a tensile force is applied downward in the longitudinal direction (X direction) to the reinforced clip 40, the clip is locked. The vertical surface of the claw 54 and the edge of the locking hole 41D of the base 41 come into contact with each other, and the reinforced clip 40 cannot be easily removed from the back surface 20B of the secondary battery pack 20.

As described above, according to the present invention, the base 41 of the reinforced clip 40 includes a pair of engaging claws 44 engaged with the guide groove 26 formed on the side surface 20D of the secondary battery pack 20. The base 41 of the reinforced clip 40 is fixed to the back surface 20B of the secondary battery pack 20 at three points, the nut 51 of the clip mounting base member 50 and the fixed portion 41B tightened by the screw 60, and the base 41 of the reinforced clip 40 is the secondary battery pack 20. It does not face the charging terminals 24 arranged near the lower end 20E of the back surface 20B. Therefore, the charging terminal 24 of the secondary battery pack 20 is not short-circuited by the metal base 41. Further, since the secondary battery pack 20 is not insert-molded with a metallic nut having a high component unit price, the cost of the secondary battery pack 20 can be reduced. Further, the clip mounting base member 50 also uses only one nut 51, and also uses only one screw 60 for fixing the reinforced clip 40 to the back surface 20B of the secondary battery pack 20, so it is sold separately. It is possible to minimize the cost increase of the reinforced clip 40. Further, when only the clip mounting base member 50 is damaged, only the damaged clip mounting base member 50 needs to be replaced, and the repair cost can be reduced.

The fixed structure of the reinforced clip for a portable electronic device according to the present invention has been proposed exclusively for the secondary battery pack 20 in which a plurality of charging terminals 24 are arranged in the vicinity of the lower end 20E as described above. However, it goes without saying that the same can be applied to a dry battery pack (not shown) used in place of the secondary battery pack 20. Further, the portable electronic device is not limited to the wireless communication device, and may be a position sensor or other sensor that transmits the position information of the user.
