In an electronic device in which a plurality of connectors are provided on the front surface of the casing, the number of connectors provided on the front surface may be reduced by reducing the area of the front surface due to downsizing of the device. When the number of connectors provided in one electronic device is reduced, it is necessary to secure the number of connectors by increasing the number of installed electronic devices. Therefore, there is a problem that it is difficult to save the installation space even if the electronic device is simply downsized. In particular, when the number of connectors required by the standard is determined, there is a problem that the number of electronic devices to be installed must be increased in order to secure the number of connectors.

The present invention has been made in view of the above, and an object of the present invention is to obtain an electronic device that can save installation space and reduce the size of a device while providing a plurality of connectors on the front surface of a casing. To do.

FIG. 1 is a perspective view of an electronic apparatus according to the first embodiment of the present invention. FIG. 2 is a front view of the electronic apparatus according to the first embodiment. FIG. 3 is a side view of the electronic apparatus according to the first embodiment.

The electronic device 10 that is a programmer logic controller includes a casing 20 provided with a plurality of connectors 30. The casing 20 has a front surface 21, a top surface 22, a bottom surface 23, a back surface 24, a right side surface 25, and a left side surface 26 and has a box shape.

The front surface 21 of the casing 20 is an inclined surface 27 having an inclination with respect to the vertical line in a side view. In the electronic device 10 according to the first embodiment, the inclined surface 27 is formed by the first inclined surface 21a that approaches the back surface 24 as it goes from the top surface 22 side to the bottom surface 23 side.

The connector 30 is provided on the inclined surface 27 and the top surface 22 formed on the front surface 21. A cable (not shown) extending from another device can be connected to the connector 30.

Connecting connectors

31 and 32 are formed on the right side surface 25 and the left side surface 26, which are side surfaces of the casing 20, for connecting to the electronic device 10 installed adjacent thereto. The connection connector 31 formed on the right side surface 25 of the casing 20 is recessed inward. The connection connector 32 formed on the left side surface 26 of the casing 20 protrudes outward. By fitting the protruding connection connector 32 into the recessed connection connector 31, the adjacent electronic devices 10 are connected to each other.

FIG. 4 is a perspective view illustrating a state in which the electronic device system 40 is configured by connecting the electronic device 10 according to the first embodiment. The connection connector 32 formed on the left side surface 26 of the casing 20 protrudes outward. By fitting the protruding connection connector 32 into the recessed connection connector 31, the adjacent electronic devices 10 are connected as shown in FIG. 4, and information can be transmitted and received through the

connection connectors

31 and 32. In addition to the electronic device 10, the electronic device system 40 can be configured by connecting the power supply unit 11 and the CPU unit 12. The power supply unit 11 supplies power to the CPU unit 12 and the electronic device 10. The CPU unit 12 controls a controlled device connected to the electronic device 10 via a cable.

According to the electronic device 10 described above, the plurality of connectors 30 are provided on the inclined surface 27 formed on the front surface 21. Here, the area of the front surface 21 on which the inclined surface 27 is formed is larger than the area of the front surface when formed with a vertical surface. Therefore, the area of the region where the connector 30 can be provided can be increased on the front surface 21 on which the inclined surface 27 is formed, rather than forming the front surface on a vertical surface. Therefore, when compared with electronic devices of the same size, the electronic device 10 having the inclined surface 27 and the front surface 21 formed has more connectors than the electronic device having the front surface formed of the vertical surface. 30 can be provided. Thereby, it becomes easy to secure the number of connectors 30 when the electronic device 10 is downsized. Further, since the number of electronic devices 10 necessary for the required number of connectors 30 is reduced, the number of installed electronic devices 10 can be suppressed and the installation space can be saved.

In the electronic device 10, more connectors 30 can be provided by providing the connectors 30 on the top surface 22 and the bottom surface 23, which are different surfaces from the front surface 21. As a result, the number of electronic devices 10 required for the required number of connectors 30 is reduced, so that the number of installed electronic devices 10 can be suppressed and the installation space can be further reduced. In addition to the front surface 21, the connector 30 may be provided on either the top surface 22 or the bottom surface 23.

In addition, a connector having a waterproof function is used in an electronic device having a waterproof function. A connector having a waterproof function tends to be larger than a connector having no waterproof function. Therefore, even if the number of connectors is the same, an electronic device having a waterproof function requires a larger area for providing the connector than an electronic device having no waterproof function. Therefore, an electronic device having a waterproof function tends to be larger than an electronic device having no waterproof function.

In the electronic device 10 according to the first embodiment, since the area of the region where the connector 30 can be provided can be increased while suppressing an increase in size of the electronic device 10 itself, the electronic device 10 has a waterproof function. Even in such a case, it is possible to suppress an increase in the size of the apparatus.

Also, when the resin is filled in the gap formed in the casing 20 and the casing 20 is formed of metal in order to ensure a waterproof function, the weight of the electronic device 10 tends to increase. In the electronic device 10 according to the first exemplary embodiment, the increase in size of the casing 20 can be suppressed by suppressing the increase in size of the apparatus. Therefore, it is possible to reduce the weight of the electronic device 10 having a waterproof function by suppressing the amount of resin used for filling the gap and the amount of metal used for forming the casing 20.

Note that the waterproof performance of an electronic device having a waterproof function is defined as a protection class in, for example, IEC 60529 and JIS C 0920. For example, if it has IP67 grade waterproof performance defined by these standards, it can be used as an electronic device having a waterproof function. Moreover, by having a waterproof function, it will also have a dust-proof function. In addition, it is a round type that is widely used in the market as a connector having a waterproof function.

Moreover, since the

connection connectors

31 and 32 formed on the right side surface 25 and the left side surface 26 of the casing 20 are fitted to each other, the adjacent electronic devices 10 can be connected to each other, so that the electronic devices are connected using a cable.

Therefore, when compared with electronic devices of the same size, the electronic device 10 having the inclined surface 27 and the front surface 21 formed has more connectors than the electronic device having the front surface formed of the vertical surface. 30 can be provided. Thereby, it becomes easy to secure the number of connectors 30 when the electronic device 10 is downsized. Further, since the number of electronic devices 10 necessary for the required number of connectors 30 is reduced, the number of installed electronic devices 10 can be suppressed and the installation space can be saved.
