Abstract: An easily assembled connector includes an insulative base (10), a plastic core (20) and conductive terminals (30). The insulative base (10) has a chamber (12). The plastic core (20) is correspondingly received in the chamber (12) and has a guiding hole (21) and troughs (22) surrounding and communicating with the guiding hole (21). Each trough (22) is formed with a terminal hole (A). The conductive terminals (30) are separately correspondingly installed in the terminal holes (A).

Abstract: A connector includes a terminal group installed in a base, an inner socket fixed onto the base for passing the terminal group, and a positioning ring including a ring plate sheathed on the inner socket, and elastic plates and hooks connected to the ring plate. The elastic plates are spaced from each other and arranged circularly on the ring plate; the hooks are formed on the elastic plate and configured to be different or partially the same up to an axial distance of the horizontal plane; the outer socket includes an outer circular seat outside the inner socket and connected to an outer circular plate of the outer circular seat; the outer circular plate has notches corresponding to the hooks; the outer circular seat is sheathed on the positioning ring to protrude the hook from the notches. The connector further includes a socket structure for engaging the plug structure.

Abstract: An anti-loosing connector for coupling with a corresponding connector has a tubular body, a nut sleeve and an elastic clamping ring. A plurality of terminals is arranged in the tubular body. The tubular body is inserted in the nut sleeve, and a thread for screwing the corresponding connector is arranged on the nut sleeve. The elastic clamping ring surrounding the nut sleeve is disposed between the tubular body and the nut sleeve. A polygonal annular surface is defined on one of the tubular body and the nut sleeve, the elastic clamping ring is fixed with the other of the tubular body and the nut sleeve, and the polygonal annular surface is pressed by the elastic clamping ring. A multi-step stopper for the elastic clamping ring is provided by the polygonal annular surface, and the tubular body and the nut sleeve are thereby prevented from relatively rotational looseness.

Abstract: A coupling structure of a cable connector includes a first connection head and a second connection head. The first connection head includes a first joint part, multiple insertion terminals, and an external threaded portion disposed on the first joint part. The second connection head includes a second joint part, multiple insertion holes, a fastening sleeve, a socket formed between the fastening sleeve and the second joint part, a positioning ring receiving the fastening sleeve, a plurality of fastening elements arranged between the positioning ring and the fastening sleeve, and a quick-release fastening ring. The quick-release fastening ring rotatably presses on the fastening elements. An internal threaded portion of each fastening element is engaged with the external threaded portion. Therefore, the first connection head and the second connection head can be securely fastened to each other and can be quickly detached from each other.

Abstract: A docking structure of a push-and-lock electrical connector includes a first connector, a second connector, and a locking part used to lock the first and second connectors. The locking part has at least one flexible locking arm having a locking portion and a latching block extending from the locking portion and protruding into the mouth of the second connector. An elastic spacing is formed between the latching block and the flexible locking arm. Thus, when the first connector is inserted into the mouth of the second connector, the latching block is latched in the latch groove of the first connector and an inner wall of the sliding shell sleeved around the second connector is pressed against the locking portion.

Abstract: An electric connector (10) includes a first connector seat (1) and a second connector seat (2). The first connector seat (1) has plural cable clamps (11), and each cable clamp (11) includes a pair of U-shaped rods (12). Each pair of U-shaped rods (12) has a pocket (121), two inner sides (122), and two outer sides (123). The two inner sides (122) have plural cable fixing slots (124), and the cable fixing slots (124) have a slot width (h) tapered towards the first connector seat (1). The second connector seat (2) has plural pins (21), and each pin (21) is passed and coupled to each pocket (121).
