The bottom side includes an electrode circuit. The illuminating member is mounted on the top side and electrically connected with the electrode circuit. The outer housing includes a connection hole to receive the circuit board and the illuminating member. The outer housing is hollow and light transmittable. The outer housing includes at least one second connection portion connected with the at least one first connection portion, respectively. Thus, the combined type single stud illuminating building block can be connected with the building block having various numbers of engaging studs to enhance degrees of freedom and variability of connection.

The present invention relates to a substrate unit and a substrate assembly, and a camera module using the same. The present invention may comprise: a first substrate part having rigidity; a second substrate part stacked on one surface of the first substrate part and having flexibility; a third substrate part extending outwardly from the second substrate part and having flexibility; and a reinforcing part which is disposed at a portion where the edge portions of the first substrate part and the third substrate part meet, the reinforcing part having a recessed portion which is formed by recessing the first substrate part inwardly so as to inhibit interference between the first substrate part and the third substrate part. The present invention is capable of resolving the interference between a rigid PCB and a flexible PCB and the tearing thereof by providing a reinforcing part in a connection portion of the rigid PCB and the flexible PCB.

A circuit board and a display device are provided. The circuit board has a device area and a peripheral area surrounding the device area. The circuit board includes a substrate, a metal layer, a first insulating layer, an adhesive layer, and an adhesive overflow detection line. The metal layer, the first insulating layer, and the adhesive layer are disposed at a same side of the substrate. The metal layer and the first insulating layer cover at least a part of the peripheral area. The metal layer is disposed between the first insulating layer and the substrate. The adhesive layer is disposed at a side of the first insulating layer away from the substrate and in the peripheral area. The adhesive overflow detection line is located in the metal layer and the metal layer in the peripheral area is provided with hollow parts; and/or the adhesive overflow detection line is located in the first insulating layer and a portion of the first insulating layer in the peripheral area has a color different from other portions.

A connecting structure for printed circuit boards has two printed circuit boards. At least one of the two printed circuit boards is a flexible printed circuit board, and each one of the two printed circuit boards has at least one connecting portion. The at least one connecting portion protrudes from an end of the printed circuit board, and is soldered on a top surface of the other printed circuit board. Each of the printed circuit boards is attached to the other printed circuit board only by a part (connecting portion), such that the solders on the connecting portion can extend forward and in two transverse directions beyond the connecting portion, thereby increasing the contact area between the solder and the top surface of the other printed circuit board. Therefore, the connecting structure can firmly connect two printed circuit boards and can enhance the resistance to pull.

A circuit board includes a protective film of such a type that a mating contact slides on the protective film and rides over a pad, and is prevented from deteriorating due to attachment and detachment. A circuit board 10 includes a plate-shaped base body 40, a pad 20 formed on a surface of the base body 40 and responsible for electrical contact with a mating contact, and a protective film 30 that spreads on the surface of the base body 40 in contact with an edge of the pad 20. The edge of the pad 20 and a portion, which contacts the edge of the pad 20, of the protective film 30 respectively have heights consecutive to each other. The pad 20 contacts, by causing the mating contact that has slid in a sliding direction in contact with the protective film 30 to ride over the pad 20, the mating contact that has ridden over the pad 20.

A peripheral device includes a manual operable device, a baseplate for carrying the manual operable device and a circuit board. The baseplate includes a plate edge extending substantially along an x-axis; a left plate indent edge, a left convex edge, a substantially linear edge, a right convex edge and a right plate indent edge are sequentially disposed on the plate edge. The circuit board includes a main portion and a flexible extension. The main portion generates a control signal in response to a triggering event at the manual operable device. The flexible extension extends substantially along a y-axis, and includes an upper end, a lower end, a y-axial left edge and a y-axial right edge; the upper end is connected to the main portion, the lower end is connected to an external connection point, and the control signal is transmitted to the external connection point via the flexible extension.

A surge protection device has a housing that is formed from a first lateral portion, a middle portion, and a second lateral portion that are connected together with a plurality of fasteners. The surge protection device includes an electronic apparatus having a neutral wire and further includes a housing that advantageously includes a strain relief that causes the neutral wire to frictionally engage the housing with sufficient friction to resist a predetermined tension applied to the free end or other portion of the neutral wire at the exterior of the housing from damaging an electrical connection between the neutral wire and a circuit board within an interior region of the surge protection device.

A connector for a display device is capable of visually detecting defects when an FPCB is connected to a PCB in the display device, e.g., a tablet and a smart phone. The connector includes a first gaff-type connection portion disposed at one end portion of a flexible printed circuit board, and a second gaff-type connection portion disposed at one end portion of a printed circuit board and fitted to the first gaff-type connection portion.
