Abstract: A digital set-top unit capable of expansion includes a first body and a second body. The first body has a first casing, a first expansion circuit substrate, and a first circuit substrate. The first casing has a first coupling side and a second coupling side. The second body has a second casing, a second expansion circuit substrate, and a second circuit substrate. The second casing has a third coupling side and a fourth coupling side. The first body and the second body are coupled together by the coupling sides of the first and second casings, such that the first expansion circuit substrate and the second expansion circuit substrate are electrically connected, allowing the first circuit substrate and the second circuit substrate to be electrically connected to each other. The digital set-top unit can be progressively expanded as needed and features unabated structural integrity and ease of use after expansion.

Abstract: A pin and a plug having the pin allow a body of the plug to enclose the pin integrally. The plug includes the body and the pin. The body has a receiving space therein for receiving the fixing segment. An insulation portion extends outward from the external surface of the body. The pin is plate-shaped and defined with an inserting segment, a fixing segment, and a burying segment therebetween. The burying segment has a burial hole and barbs, and is buried in the insulation portion. The fixing segment protrudes into the receiving space. The inserting segment is exposed from the insulation portion. The pin and the plug cut costs, speed up a manufacturing process thereof, and allow the body to be formed by a single injection molding process and thus enclose and fix the pin in place firmly.

Abstract: A mini jelly container according to the invention includes a container, at least one partition plate at an interior of the container, at least two accommodating spaces at the interior of the container and respectively filled with jellies and an opening cover for sealing. Using the aforesaid structure, without altering original shape and size of prior mini jellies, jellies are divided into smaller sizes. Thus, not only elderly people and children are allowed to eat the divided mini jellies individually for ensuring safety for eating and are prevented from choking, but also mini jellies having different flavors are offered.
