Description

An embodiment of the present invention relates to an electronic component storage case.

For example, a wireless tag used in the field of home security is configured by storing a circuit board for wireless communication and a battery inside a small and portable case in order to perform wireless communication with an external device. .. As the battery, for example, a coin battery having good availability is used. Since the battery is a consumable item, it needs to be replaced as appropriate. However, the user often opens the case to replace the battery. Therefore, the case used for the wireless tag or the like is required to have a configuration that can be easily opened by the user from the viewpoint of easy battery replacement.

On the other hand, for example, since coin batteries are small, if the case is accidentally opened while an infant is playing with a wireless tag, the possibility that the infant will take out the battery and swallow it will increase. .. Therefore, it is important that the case used for the wireless tag or the like has a configuration that cannot be easily opened by an infant or the like from the viewpoint of preventing accidental ingestion of the battery by the infant or the like.

Therefore, in the conventional configuration, a configuration is considered in which a groove is provided in the case, and a predetermined tool, for example, a coin that the user is supposed to normally carry, is inserted into the groove to open the case. According to this, when opening the case, it is necessary to insert a coin etc. into the groove, so it is possible to prevent infants etc. from accidentally opening the case while playing with the wireless tag. As a result, accidental ingestion of the battery can be suppressed. However, in the conventional configuration, even if a tool such as a coin is used, a strong force is required when opening the case. Therefore, in the conventional configuration, there is room for improvement in the ease of opening the case.

JP-A-2007-299803

The present invention has been made in view of the above circumstances, and an object of the present invention is that it cannot be easily opened when an attempt is made to open it with bare hands without using a tool such as a coin, and a tool such as a coin is used. In some cases, it is to provide an electronic component storage case that can be easily opened.

(Claim 1)
The electronic component storage case according to claim 1 has a storage section that can store electronic components including a battery inside, and is configured to be separable into a first case member and a second case member. The electronic component storage case includes a fitting portion and a groove portion. The fitting portion receives and fits the claw portion provided on one of the first case member or the second case member and the claw portion provided on the other of the first case member or the second case member. The first case member and the second case member are separably coupled to each other by fitting the claw portion into the receiving portion. The groove portion is formed by recessing the side surfaces of either or both of the first case member and the second case member.

According to this configuration, the first case member and the second case member can be firmly connected by securing the fitting portion longer by the long fitting portion. This makes it difficult to open the electronic component storage case, for example, with bare hands, and as a result, infants and the like accidentally open the electronic component storage case, and parts such as batteries stored inside the electronic component storage case. It is possible to prevent the situation of accidentally swallowing. Then, when the user opens the case, that is, separates the first case member and the second case member, the user puts a plate-shaped and rigid tool such as a coin in the groove formed on the side surface of the case. Insert and apply force to the first and second cases using the principle of leverage. As a result, the fitting portion is disengaged, and the first case member and the second case member are separated.

In this case, if the long fitting portion is lengthened, the first case member and the second case member can be more firmly connected, but a stronger force is required when opening the case, and the coin It becomes difficult to open even if you use tools such as. Therefore, in this configuration, the portion of the entire fitting portion closest to the groove portion is the end portion of the fitting portion.

That is, in general, when such a long fitting portion is separated, the greatest force is required at the initial stage of the separation, that is, when the separation starts. That is, the force applied to the groove portion from a tool such as a coin is transmitted to the fitting portion, whereby the fitting portion between the claw portion and the receiving portion in the fitting portion begins to be disengaged. Then, once the claw portion and the receiving portion are disengaged, even a relatively small force is subsequently disengaged from the disengaged portion in a chain reaction.

Here, assuming that the user's force is transmitted to the central portion of the fitting portion in the longitudinal direction, the force transmitted to the fitting portion is dispersed over the entire fitting portion along the longitudinal direction of the fitting portion. Therefore, in such a configuration, when the fitting portion starts to separate, it is difficult for the user's force to be efficiently transmitted to the fitting portion, and the force loss is large. A large force is required to start separating from the receiving part.

On the other hand, in this configuration, the portion of the entire fitting portion closest to the groove portion is the end portion of the fitting portion. Therefore, in the initial stage of separating the claw portion and the receiving portion of the fitting portion, the force applied to the groove portion from a tool such as a coin can be concentrated on the end portion of the fitting portion. As a result, the force applied to the groove portion from a tool such as a coin can be efficiently transmitted to the fitting portion, and as a result, the fitting portion can be separated and the case can be opened with a lighter force than before.

In this way, the electronic component storage case of this configuration cannot be easily opened when it is opened with bare hands without using a tool such as a coin, and it can be easily opened when it is opened with a tool such as a coin. it can. As a result, according to this configuration, it is possible to prevent an infant or the like from accidentally opening the electronic component storage case and accidentally swallowing the internal battery or the like, and electronically when replacing the battery or the like. It is possible to improve both workability that the component storage case can be easily opened with a light force.

(Claim 2)
In the configuration according to claim 2, the groove portion is provided at a position including an intersection on an extension line of two linear portions arranged adjacent to each other in the fitting portion. According to this, when a tool such as a coin is inserted into the groove portion, the point of action of the coin can be brought as close as possible to the ends of two adjacent straight portions of the fitting portion. Therefore, the force applied to the groove portion by the user using a tool such as a coin is efficiently transmitted to the ends of two adjacent straight portions of the fitting portion. Then, the fitting portion starts to come off at the two end portions almost at the same time, and then the other portions also come off sequentially along the straight line portion. As described above, according to this configuration, since the two ends of the fitting portion can be started to be removed almost at the same time, the first case member and the second case member can be separated more easily and quickly, that is, the electronic component can be stored. You can open the case.

(Claim 3)
The electronic component storage case according to claim 3 includes a fitting portion and a groove portion, similarly to the electronic component storage case according to claim 1. Then, in the present configuration, the portion of the entire fitting portion closest to the groove portion is a corner portion where the fitting portion is bent.

Even with this configuration, the same action and effect as the configuration according to claim 1 can be obtained. That is, even with this configuration, the force applied to the groove portion from a tool such as a coin can be concentrated on the corner portion of the fitting portion. As a result, the force applied to the groove portion from a tool such as a coin can be efficiently transmitted to the fitting portion, and as a result, the fitting portion can be separated and the case can be opened with a lighter force than before. ..

(Claim 4)
The electronic component storage case according to claim 4 includes a fitting portion and a groove portion, similarly to the electronic component storage case according to claim 1. Then, in the present configuration, the portion of the entire fitting portion closest to the groove portion is the shortest portion of the straight portion of the fitting portion in the entire fitting portion.

According to this, since the fitting portion 20 is shorter than the other straight portions, the fitting can be released with a smaller force than when a force is applied to these other straight portions. .. Therefore, according to this, although it does not reach the configuration of each of the above claims, the fitting portion can be separated and the electronic component storage case can be opened with a lighter force as compared with the conventional configuration.

(Claim 5)
In the configuration according to claim 5, the portion of the entire fitting portion closest to the groove portion is chamfered. That is, the portion of the entire fitting portion closest to the groove portion is a portion where a force acts at the beginning of opening the electronic component storage case using a tool such as a coin. Then, by chamfering the portion where the force acts at the beginning of the opening, it is possible to weaken the fitting between the claw portion and the receiving portion in the chamfered portion. As a result, when the user uses a tool such as a coin, the electronic component storage case can be opened with a smaller force.

(Claim 6)
In the configuration according to claim 6, the electronic component storage case is made of a waterproof material, and the first case member and the second case member are coupled to each other in a state where the first case member and the second case member are connected. It is further provided with a waterproof member sandwiched between the two case members. The fitting portion is arranged outside the prevention member and along the periphery of the storage portion.

According to this, by fitting the claw portion and the receiving portion of the fitting portion on the outside of the waterproof member, the waterproof member can be strongly compressed by the first case member and the second case member. Therefore, it is possible to efficiently suppress the invasion of external moisture through the gap between the joint portion between the first case member and the second case member. As a result, high waterproofness inside the electronic component storage case can be ensured, and as a result, defects of the battery and electronic components due to the influence of moisture can be suppressed.

(Claim 7)
Here, for example, a circuit board is used as an electronic component to be stored in an electronic component storage case, but usually, since a plurality of circuit boards having the same shape are manufactured at once, many of them have a rectangular shape. Therefore, by making the electronic component storage case and the storage portion rectangular, the rectangular electronic substrate can be arranged inside without wasting space. However, since the coin battery stored in the electronic component storage case, for example, has a disk shape, if the electronic component storage case and the storage portion are rectangular, the corners become dead spaces and are wasted.

Therefore, in the configuration according to claim 7, the first case member and the second case member are formed in a rectangular shape in a state of being connected to each other, and the groove portion is provided at a rectangular corner portion. ing. According to this, by forming the first case member and the second case member in a rectangular shape, it is possible to efficiently arrange rectangular electronic components such as a circuit board without wasting space. Further, the groove portion is provided at a rectangular corner portion. In this way, by providing grooves in the corners that tend to be dead spaces when the electronic component storage case and the storage section are rectangular, the space inside the storage section can be effectively used, and as a result, the large size of the electronic component storage case can be used. It is possible to secure the area of the groove as wide as possible and improve the operability when opening the electronic component storage case while suppressing the formation.

(Claim 8)
In the configuration according to claim 8, a hole formed through the first case member and the second case member is formed in a portion of the four corners in the rectangular shape where the groove is not provided. There is. The user can pass, for example, an annular key ring through the hole. As a result, even when the user removes the claw portion and the receiving portion of the fitting portion to separate the first case member and the second case member, the first case member and the second case member are separated from each other. It can be prevented from doing so. Then, by forming the holes in the four corners of the rectangular shape where the grooves are not provided, it is possible to effectively utilize the corners that tend to be dead spaces. As a result, it is not necessary to enlarge the first case member and the second case member in order to provide the hole portion, and as a result, it is possible to suppress the increase in size of the electronic component storage case.

In this case, if the elongated fitting portion 20 is lengthened, the first case member 11 and the second case member 12 can be more firmly connected, but even stronger force is applied when opening the case 10. It is necessary, and it becomes difficult to open it even with a tool such as a coin 90. Therefore, in the present embodiment, the portion of the entire fitting portion 20 closest to the groove portion 13 is the end portions 211 and 221 of the fitting portion 20.

That is, in general, when such a long fitting portion 20 is separated, the greatest force is required at the initial stage of the separation, that is, when the separation starts. That is, the force applied to the groove portion 13 from a tool such as the coin 90 is transmitted to the fitting portion 20, whereby the fitting portion 201 and the receiving portion 202 in the fitting portion 20 begins to be disengaged. Then, once the claw portion 201 and the receiving portion 202 are disengaged, even with a relatively small force, the claw portion 201 and the receiving portion 202 are sequentially disengaged from the disengaged portion.

Here, assuming that the user's force is transmitted to the central portion of the fitting portion 20 in the longitudinal direction, the force transmitted to the fitting portion 20 is distributed to the entire fitting portion 20 along the longitudinal direction of the fitting portion 20. Will end up. Therefore, in such a configuration, when the fitting portion 20 starts to separate, it is difficult for the user's force to be efficiently transmitted to the fitting portion 20, and the force loss is large, so that the fitting portion 20 A large force is required to start separating the claw portion 201 and the receiving portion 202.

On the other hand, according to the present embodiment, the portion of the entire fitting portion 20 closest to the groove portion 13 is the end portions 211 and 221 of the fitting portion 20. Therefore, in the initial stage of separating the claw portion 201 and the receiving portion 202 of the fitting portion 20, the force applied to the groove portion 13 from a tool such as a coin 90 is applied to the end portions 211 and 221 of the fitting portion 20. You can concentrate. As a result, the force applied to the groove portion 13 from a tool such as a coin 90 can be efficiently transmitted to the fitting portion 20, and as a result, the fitting portion 20 is separated with a lighter force than before, and the case 10 is used. Can be opened.

As described above, the case 10 of the present embodiment cannot be easily opened when it is opened with bare hands without using a tool such as a coin 90, and can be easily opened when it is opened with a tool such as a coin 90. Can be done. As a result, according to the present embodiment, it is possible to prevent an infant or the like from accidentally opening the case 10 and accidentally swallowing the internal battery 51 or the like, and when replacing the battery 51 or the like. In addition, workability that the case 10 can be easily opened with a light force and both can be improved.

Further, the groove portion 13 is provided at a position including two straight portions of the fitting portion 20 arranged adjacent to each other, in this case, an intersection P on an extension line between the first straight portion 21 and the second straight portion 22. ing. According to this, when a tool such as a coin 90 is inserted into the groove portion 13, the point of action of the coin 90 is set as much as possible at the ends 211 and 221 of two adjacent straight portions 21 and 22 of the fitting portion 20. You can get closer. Therefore, the force applied to the groove portion 13 by the user using a tool such as a coin 90 is efficiently transmitted to the end portions 211 and 221 of the two adjacent straight portions 21 and 22 of the fitting portion 20, thereby. , The fitting portion 20 begins to come off at the two end portions 211 and 221 almost at the same time, and then the other portions also come off sequentially along the straight portion 211 and 221. As described above, according to the present embodiment, since the two end portions 211 and 221 of the fitting portion 20 can be started to be removed almost at the same time, the first case member 11 and the second case member 12 can be more easily separated. And it can be separated quickly, that is, the case 10 can be opened.

Further, the portion of the entire fitting portion 20 closest to the groove portion 13, in this case, the end portion 211 of the first straight portion 21 and the end portion 221 of the second straight portion 22 are chamfered. That is, the portions 211 and 221 of the entire fitting portion 20 closest to the groove portion 13 are locations where a force acts at the beginning of opening the case 10 using a tool such as a coin 90. Then, by chamfering the portions 211 and 221 on which the force acts at the beginning of the opening, the fitting between the claw portion 201 and the receiving portion 202 at the chamfered portion can be weakened. As a result, when the user uses a tool such as a coin 90, the case 10 can be opened with a smaller force.

Further, the case 10 further includes a waterproof member 15. The waterproof member 15 is made of a waterproof material, and is sandwiched between the first case member 11 and the second case member 12 in a state where the first case member 11 and the second case member 12 are coupled. ing. The fitting portion 20 is arranged outside the waterproof member 15 and along the periphery of the storage portion 101.

According to this, by fitting the claw portion 201 and the receiving portion 202 of the fitting portion 20 on the outside of the waterproof member 15, the waterproof member 15 is strongly compressed by the first case member 11 and the second case member 12. can do. Therefore, the invasion of external moisture can be efficiently suppressed from the gap of the joint portion between the first case member 11 and the second case member 12. As a result, high waterproofness in the case 10 can be ensured, and as a result, defects of the battery 51 and the electronic component 52 due to the influence of moisture can be suppressed.

Here, for example, a circuit board is used as the electronic component 52 housed in the case 10, but usually, since a plurality of circuit boards having the same shape are manufactured at once, many of them have a rectangular shape. Therefore, by making the case 10 and the storage portion 101 rectangular, the rectangular electronic substrate can be arranged in the storage portion 101 without wasting space. However, since the coin battery 51 stored in the case 10, for example, has a disk shape, if the case member 11 and the storage portion 101 are made rectangular, the corners, that is, the corners become dead spaces and are wasted.

Therefore, according to the present embodiment, the first case member 11 and the second case member 12 are formed in a rectangular shape in a state of being connected to each other. The groove portion 13 is provided at a rectangular corner portion. According to this, by forming the first case member 11 and the second case member 12 in a rectangular shape, the rectangular electronic component 52 such as a circuit board can be efficiently arranged without wasting space. Further, the groove portion 13 is provided at a rectangular corner portion. In this way, by providing the groove portion 13 at the corner portion which tends to be a dead space when the case 10 and the storage portion 101 are rectangular, the space inside the storage portion 101 can be effectively utilized, and as a result, the large size of the case 10 is obtained. It is possible to secure the region of the groove portion 13 as wide as possible and improve the operability when opening the case 10 while suppressing the formation.

Further, according to the present embodiment, a hole portion 14 formed through the first case member 11 and the second case member 12 is formed in a portion of the four corner portions in the rectangular shape where the groove portion 13 is not provided. Has been done. The user can pass, for example, an annular key ring 91 through the hole 14. As a result, even when the user removes the claw portion 201 and the receiving portion 202 of the fitting portion 20 and the first case member 11 and the second case member 12 are separated, the first case member 11 and the second case It is possible to prevent the members 12 from being separated from each other. Then, by forming the hole portion 14 in a portion of the four corner portions in the rectangular shape where the groove portion 13 is not provided, the corner portion that tends to be a dead space can be effectively utilized. As a result, it is not necessary to enlarge the first case member 11 and the second case member 12 in order to provide the hole portion 14, and as a result, it is possible to suppress the increase in size of the case 10.
