[Problems to be Solved by the Invention]

In the inventions disclosed in JP-A-11-178211 and JP-A-11-113133 described above, individual parts are assembled in one plastic body, but the number of parts such as cables is large. Many are complicated and costly. However, in reality, the components shown in FIGS. 3 and 4 are mounted on a printed circuit board, particularly a printed circuit board of an uninterruptible power supply, to supply power to the device and further distribute the power from the printed circuit board. There is a desire to do so.

【0004】

The present invention has been made to solve the above-mentioned problems, and can be easily mounted on a printed circuit board with an integrated simple structure having a small number of parts, and power is supplied to the mounted place as well as there. The purpose is to provide an inexpensive AC outlet that can further distribute power from.

[Means for solving problems]

In order to solve the above-mentioned problems, in the present invention, an inlet, a circuit breaker, and a plurality of outlets are integrally incorporated in a frame, and a socket or a plug is inserted into and removed from the inlet or the plurality of outlets. A printed circuit board-mounted AC outlet that can be mounted on a printed circuit board so that the insertion / removal surfaces of multiple outlets are orthogonal to the printed circuit board. One end is connected to the inlet and the connection terminals built into the multiple outlets. The other end has a right angle pin for inserting a printed circuit board that extends so as to be parallel to the insertion / removal surface on the opposite side of the insertion / removal surface of the inlet or a plurality of outlets.

【0006】

According to such a configuration, since each part is integrated in the frame, the number of parts is small, and the right angle pin can be inserted into the hole of the printed circuit board and soldered to the printed circuit board. It's easy.

【0007】

Further, in the present invention, a part of the frame has a frame holding terminal shape portion for mounting the printed circuit board, and the frame holding terminal shape portion is inserted into a hole of the printed circuit board together with a right angle pin when mounted on the printed circuit board. And made solderable. With such a configuration, the strength against insertion and removal of a socket or a plug into an inlet or a plurality of outlets is increased.

【0008】

Further, in the present invention, when the AC outlet is mounted on the printed circuit board, the AC power supplied to the inlet is supplied to the uninterruptible power supply through the wiring pattern of the circuit breaker and the printed circuit board, and the AC power supply is supplied from the uninterruptible power supply. Power is distributed to the outlets via the printed circuit board wiring pattern. Therefore, it is possible to easily protect the overcurrent of the uninterruptible power supply and distribute the power supply to the devices connected to the uninterruptible power supply.

【0009】

Further, in the present invention, when the AC outlet is mounted on the printed circuit board, the AC power supplied to the inlet is transmitted to the inlet via the circuit breaker and the wiring pattern of the printed circuit board according to the wiring pattern of the plurality of outlets. AC power can be distributed from each. Therefore, the inlet, the circuit breaker, and the plurality of outlets can be easily connected by the wiring pattern of the printed circuit board, no cable or the like is required, the structure is not complicated, and the configuration can be inexpensive.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 (a) is a perspective view of an embodiment of the AC outlet of the present invention as viewed from the rear, and FIG. 1 (b) is a perspective view and a view of the AC outlet shown in FIG. 1 (a) as viewed from the front. 2 is a connection diagram for explaining the connection relationship of each part of the AC outlet of FIG. The AC outlet 100 shown in FIG. 1 has four outlets 21, 22, 23, 24, one inlet 30, and one circuit breaker integrated in a frame 10 having a rectangular cross section. Has 40 and. Frame holding terminals 11 are arranged on both side surfaces of the frame 10. The outlets 21, 22, 23, 24 and the inlet 30 have terminals L, FG, and N, respectively, and the circuit breaker 40 has terminals C and D, respectively.

【0011】

Terminals L, FG, N of outlets 21,22,23,24 are conductors 51,52, extending along the back of outlets 21,22,23,24, as shown in FIG. 1 (a), on the back of outlets 21,22,23,24. Each is connected by 53. The open end of conductors 51,52,53 extends perpendicular to conductors 51,52,53 and is connected to right angle pins 61,62,63. In the case of FIG. 1, the conductors 51,52,53 and the right angle pins 61,62,63 are formed as one with rigidity. The terminal L of the inlet 30 is connected to the terminal C of the circuit breaker 40, and the terminals D of the circuit breaker 40 and the terminals FG and N of the inlet 30 are rigid as in the case of the outlets 21, 22, 23 and 24, respectively. It is connected to the right angle pins 31, 32, 33.

【0012】

When the above-mentioned AC outlet 100 is assembled as an input / output outlet to the printed circuit board 12 of an uninterruptible power supply, for example, the frame holding terminal 11 and the right angle pins 31, 32, 33, 61, 62, 63 correspond to the printed circuit board 12. Insert it into the through hole to be used and solder it to the wiring pattern (not shown) of the printed circuit board 12. In the case of a printed board of an uninterruptible power supply (not shown), the soldered wiring pattern of the right angle pins 31, 32, 33 becomes the power input line of the uninterruptible power supply, and the circuit breaker for the uninterruptible power supply. Since the power supply current is supplied via 40, the circuit breaker 40 cuts off the overcurrent when the overcurrent flows. In addition, the soldered wiring pattern of the right angle pins 61, 62, 63 becomes the power output line of the uninterruptible power supply, and the uninterruptible power supply is supplied to the devices such as computers connected to the outlets 21, 22, 23, 24. Will be done.

【0013】

Furthermore, when applying to other than the printed circuit board of the uninterruptible power supply, for example, when power is supplied to the circuit mounted on the printed circuit board and power is distributed from the outlets 21, 22, 23, 24, the wiring pattern is used. For example, the right angle pins 31, 32, 33 may be configured to be connected corresponding to the right angle pins 61, 62, 63, respectively. In such a configuration, the terminal L of the inlet 30 is connected to the terminal L of the outlets 21, 22, 23, 24 via the circuit breaker 40, the right angle pin 31, the wiring pattern, and the right angle pin 61. The terminal FG of the inlet 30 is connected to the terminal FG of the outlets 21, 22, 23, 24 via the right angle pin 32, the wiring pattern, and the right angle pin 62. The terminal N of the inlet 30 is connected to the terminal N of the outlets 21, 22, 23, 24 via the right angle pin 33, the wiring pattern, and the right angle pin 63.

【0014】

In the AC outlet 100, the frame holding terminal 11 and the right angle pins 31, 32, 33, 61, 62, 63 are made of rigid conductors, so that when assembled to the printed circuit board 12, the angle pin is attached to the inlet 30. It has a structure that is strong against insertion and removal of sockets (not shown) and insertion and removal of plugs for outlets 21, 22, 23, 24. Further, since the printed circuit board 12 is usually mounted horizontally on the device, the insertion / removal surface of the inlet or outlet faces the side surface, which is convenient. Further, when a socket (not shown) or the like is attached to the inlet 30 of the AC outlet 100 and AC power is supplied, power can be supplied to the uninterruptible power supply and the circuit arranged on the printed circuit board 12. At the same time, AC power can be distributed and supplied to a desired department via outlets 21, 22, 23, 24 (of course, it is also possible to configure so that only distributed supply is performed). In this case, the maximum value of the power supply current to be supplied is appropriately limited by the standard of the circuit breaker 40.

In addition, a part of the frame has a frame holding terminal shape portion for mounting the printed circuit board, and is solderable to the printed circuit board, whereby sockets or plugs can be inserted or removed from the inlet or a plurality of outlets. Increases strength.
