The USB-Type-A interface 60b has a VBUS terminal 61b and a D+/D- terminal 62b. Unlike the USB-Type-C interface 60a described above, the CC terminal 63a is omitted. Therefore, the USB-Type-A interface 60b does not have the function of identifying the state of the connected external device 10b.

The USB-Type-A interface 60b is supplied with power from the power supply circuit 12 and supplies power to the external device 10b via the VBUS terminal 61b. For example, the voltage supplied to the USB-Type-A interface 60b by the power supply circuit 12 is 5V. Also, the USB-Type-A interface 60b transmits signals to the external device 10b via the D+/D- terminals 62b.

The USB hub 53 electrically connected to the USB-Type-A interface 60 b is controlled by the host controller 342 of the USB controller 34 via the system bus 41 . In other words, the USB-Type-A interface 60b is controlled by the host controller 342. FIG.

Note that the USB-Type-A interface 60c shown in FIG. 7 has the same configuration as the USB-Type-A interface 60b shown in FIG. 6, so description thereof will be omitted.

Next, referring to FIG. 8, the USB-Type-B interface 60d will be described. FIG. 8 is a block diagram of the USB controller 34 and USB-Type-B interface 60d.

The USB-Type-B interface 60d has a VBUS terminal 61d and a D+/D- terminal 62d. Unlike the USB-Type-C interface 60a described above, the CC terminal 63a is omitted. Therefore, the USB-Type-B interface 60d does not have the function of identifying the state of the connected external device 10d.

The USB-Type-B interface 60d is supplied with power from the power supply circuit 12, and supplies power to the external device 10d via the VBUS terminal 61d. For example, the voltage supplied to the USB-Type-B interface 60d by the power supply circuit 12 is 5V. Also, the USB-Type-B interface 60d transmits signals to the external device 10d via the D+/D- terminals 62d.

The USB-Type-B interface 60 d is controlled by the device controller 341 of the USB controller 34 via the system bus 41 .

In other words, unlike the USB-Type-A interfaces 60b and 60c, the USB-Type-B interface 60d is controlled by the USB controller 34 without going through the USB hub 53. FIG. Note that the USB-Type-B interface 60 d may be configured to be controlled by the USB controller 34 via the USB hub 53 .

1-8. Support Member The support member 600 will be described with reference to FIG. 15 . 15 is a perspective view of the support member 600. FIG.

The support member 600 has a fixed portion 601 and an exposed portion 602 . The support member 600 has steps 610a, 610b, 610c and 610d, and the fixed surface 606 of the fixed portion 601 and the exposed surface 607 of the exposed portion 602 are connected via the steps 610a, 610b, 610c and 610d. be.

Also, the fixed surface 606 and the exposed surface 607 are preferably parallel. In this case, it is preferable that the fixed surface 606 contacts the inner surface of the first connector surface 221 and the exposed surface 607 is flush with the outer surface of the first connector surface 221 without steps. That is, the fixing surface 606 contacts the inner surface of the first connector surface 221, thereby fixing the support member 600 more firmly. Further, since the exposed surface 607 is on the same surface as the first connector surface 221, the user can easily insert and remove the plug 401a of the USB-Type-C cable 400a into and out of the USB-Type-C receptacle connector 320a. Due to manufacturing errors, the fixed surface 606 and the exposed surface 607 may not be completely parallel, but in such a case they are assumed to be parallel.

Moreover, the fixing surface 606 of the fixing portion 601 is larger than the exposed surface 607 of the exposed portion 602 , and the exposed portion 602 is provided near the center of the fixing surface 606 of the fixing portion 601 . That is, when the support member 600 is viewed from above, the exposed portion 602 has a trapezoidal shape in which the upper base is on the side of the step 610a and the lower base is on the side of the step 610b. The lower base is longer than the upper base. Therefore, the direction in which the exposed portion 602 fits into the opening 220a is constant. Thus, since the exposed surface of the exposed portion 602 is not completely symmetrical vertically and horizontally, the risk of the exposed portion 602 being reversely fitted into the opening 220a is reduced, and the handling of the support member 600 is facilitated. Become.

Also, the holes 651 and 652 of the fixed portion 601 are located outside the exposed portion 602 . That is, the holes 651 and 652 are provided on the opposite side of the fixing hole 620 with respect to the steps 610c and 610d. Note that the fixed portion 601 and the exposed portion 602 may be integrally formed, or may be formed separately and then joined. Further, holes 651 and 652 are provided in the fixing portion 601 , and the holes 651 and 652 are connected to the screws 351 and 352 via the first connector surface 221 . Specifically, the screw 351 is fixed to the fixed substrate 640 via the opening 220p and the hole 651, and similarly the screw 352 is fixed to the fixed substrate 640 via the opening 220q and the hole 652.

In this manner, the screws 351 and 352 are screwed to the fixed substrate 640 at a plurality of locations, and the support member 600 exposes the exposed surface 607 from the opening 220a to the outside, and the first connector surface 221 and the fixed substrate 640 are connected to each other. connected to That is, the support member 600 is fixed between the first connector surface 221 and the fixed substrate 640 . The exposed surface 607 is exposed to the outside of the first connector surface 221 through the opening 220a, but the fixing surface 606 is not exposed to the outside from the first connector surface 221. As shown in FIG.

For example, if the support member 600 is fixed at one point by one screw 351, the position of the support member 600 may be displaced such that the support member 600 rotates about the fixed point. When the position of the support member 600 is displaced in this way, a gap is formed between the opening 220a and the exposed surface 607, and foreign matter such as dust and insects enter the connector section 220 through this gap. The Type-C interface 60a and the connected external device 10a may malfunction. In addition, due to this gap, the connection between the support member 600 and the first connector surface 221 may be weaker than in the case of fixing at two points.

A fixing hole 620 is provided near the center of the support member 600 . Since the fixing hole 620 is a hole provided to support the USB-Type-C receptacle connector 320a, it is preferable that there is no gap between the fixing hole 620 and the USB-Type-C receptacle connector 320a. . As shown in FIG. 15, since the USB-Type-C receptacle connector 320a has a cylindrical shape, the size of the fixing hole 620 is about the same as the size of the opening 321a of the USB-Type-C receptacle connector 320a. If there is, the gap between the fixing hole 620 and the USB-Type-C receptacle connector 320a can be reduced.

That is, the support member 600 is formed around the outer surface of the USB-Type-C receptacle connector 320a to support the USB-Type-C receptacle connector 320a. Note that the opening 321a of the USB-Type-C receptacle connector 320a is exposed from the exposed surface 607 to the outside.

Further, when the sum of the thickness T1 of the fixed portion 601 and the thickness T2 of the exposed portion 602 is approximately the same as the depth D of the USB-Type-C receptacle connector 320a shown in FIG. The USB-Type-C receptacle connector 320a can be efficiently supported. Here, if the thickness T2 of the exposed portion 602 is approximately the same as the thickness of the first connector surface 221, the supporting member 600 is fixed to the first connector surface 221 without the exposed portion 602 protruding from the opening 220a. It is firmly fixed between substrates 640 .

In order to firmly fix the support member 600 between the first connector surface 221 and the fixed substrate 640, all of the steps 610a, 610b, 610c and 610d are preferably in contact with the opening 220a. In other words, it is preferable that the exposed portion 602 be tightly fitted into the opening 220a. As a result, the exposed portion 602 of the support member 600 is firmly fixed to the opening 220a, and the USB-Type-C receptacle connector 320a is strong against an external force load such as prying of the plug 401a of the USB-Type-C cable 400a. have the effect of

Due to manufacturing errors, some of the steps 610a, 610b, 610c, and 610d may not be in contact with the opening 220a. That is, the outer circumference of the exposed surface 607 substantially matches the opening 220a.

Also, the support member 600 can be replaced with a wired connector that can be connected to a plug of a cable different from the plug 401a of the USB-Type-C cable 400a. That is, the wired connector transfers data based on a different standard than the USB-Type-C receptacle connector 320a.

For example, in FIG. 12, a USB-Type-C receptacle connector 320a supported by a support member 600 is secured in opening 220a, but instead of this support member 600, for example, a serial, parallel, flanged USB-Type -A, and a wired connector such as a flanged USB-Type-B receptacle connector may be secured to opening 220a. This allows the user to apply different types of receptacle connectors without changing the shape of the opening 220a.

Also, the support member 600 may be configured to support a USB receptacle connector of a standard different from USB-Type-C320a. For example, the support member 600 may be configured to support receptacle connectors conforming to standards such as micro-USB-Type-B and mini-USB-Type-B.

The +Xa direction corresponds to the +Y direction shown in FIGS. 9 to 11, and the +Ya direction corresponds to the -Z direction shown in FIGS.

As shown in FIG. 20, support member 700 supports USB-Type-C receptacle connectors 320a and 320g. In this case, the USB-Type-C receptacle connectors 320a and 320g are arranged so that the long sides 332a and 333a and the long sides 332g and 333g are perpendicular to the substrate 300, which is the so-called It is arranged vertically.

Although FIG. 20 shows an example in which the USB-Type-C receptacle connector 320g is arranged in the +Xa direction from the USB-Type-C receptacle connector 320a, it may be arranged in reverse. In other words, the USB-Type-C receptacle connector 320g may be arranged in the -Xa direction than the USB-Type-C receptacle connector 320a.

As shown in FIG. 21, USB-Type-C receptacle connector 320g has the same configuration as USB-Type-C receptacle connector 320a. In other words, USB-Type-C receptacle connector 320g has planar portions 322g, 323g, connecting portions 324g, 325g, and rear portion 326g. The flat portions 322g, 323g are connected by connecting portions 324g, 325g, and the USB-Type-C receptacle connector 320g has a generally cylindrical shape.

The opening 321g has linear long side portions 332g and 333g and arcuate short side portions 334g and 335g.

Support member 700 is secured to first connector surface 221 by screws 351 and 352 . Screws 351 and 352 pass through support member 700 and are screwed to fixed substrate 740 .

Therefore, when the screws 351 and 352 are metal screws, the fixed substrate 740 is fixed at the same potential as the first connector surface 221 . For example, the fixed substrate 740 is fixed to the ground potential, which has the effect of removing the static electricity charged on the fixed substrate 740, as in the first embodiment, and also has the effect of making the fixed substrate 740 resistant to noise. There is Details of the support member 700 will be described later.

In the USB-Type-C receptacle connector 320a supported by the support member 700, the long side 333a is located in the +Xa direction from the long side 332a, and the short side 334a is located in the +Ya direction from the short side 335a. are placed so that Here, the distance between the mounting surface 301 of the substrate 300 and the arcuate short side portion 335a is defined as the distance L1. That is, the distance L1 is the shortest distance from the mounting surface 301 of the board 300 to the apex of the arc of the short side portion 335a.
