A push-on switch includes an insulating housing (1) defining a recess (10) at its top, a first fixed contact (21) and a second fixed contact (22) received at the bottom of the recess (10), a dome shaped movable contact (3) with the bottom end placed on the first fixed contact and the bottom face facing the second fixed contact, an actuator (4) over the movable contact, and a metal shell (6) shielding over the insulating housing. The actuator is made of an elastomer and includes a tubular periphery part (41), an operation part (43), a thin-walled part (42) inclining downwardly from the bottom of the operation part and connecting the operation part with the periphery part, a pressing part (431) downwardly protruding from the operation part and resisting on the top surface of the movable contact, and a retaining part (44) extending from the top of the periphery part.

A tact switch includes an insulative housing, a first conductive electrode, a second conductive electrode, an actuator and a metal cover. The insulative housing defines a receiving cavity which is provided with a fixed terminal and a movable terminal movably contacting with the fixed terminal. The first and second conductive electrodes are received in the receiving cavity. The second conductive electrode is located above and separated from the first conductive electrode. The actuator includes a ring portion defining a through hole at a center thereof, a press seat received in the through hole and defining a receiving groove and an elastic element received in the receiving groove. The metal cover is secured to the insulative housing and fixes the actuator in the insulative housing. When the ring portion is pushed by an exterior force, the elastic element drives the movable terminal to contact with the fixed terminal and a distance change between the first and second conductivity electrodes. And after the movable terminal can not further be moved, the distance between the first and second electrodes further change smaller due to own elasticity of the elastic element made from elastic material.

A card connector (100) includes an insulative housing (10), a number of contacts (30) retained in the insulative housing, a metal shell (20) attached to the insulative housing for cooperatively defining a receiving space (60), and a tray (40) received in the receiving space. The metal shell includes a pair of elastic portions (24). The tray has a frame portion (41) having two lateral edges. Each lateral edge has a notch (410), a dent (415), and a projecting portion (411) between the notch and the dent. The elastic portion is secured with the notch when the tray is fully inserted in the receiving space along an insertion/ejection direction.

An I/O connector (100) includes an insulative housing (10) having a base portion (11) and a fitting portion (12) extending forwardly from the base portion, a number of terminals (30) retained in the insulative housing, and a metal covering portion (20) integrally molded with the insulative housing. The metal covering portion has a main portion (21) embedded with the base portion, a pair of deflexed side portions (22) engaging with two sides of the fitting portion, and a front portion (23) engaging with a front edge of the fitting portion. The main portion defines a slit (212) and forms a corresponding slant portion (213) extending into the slit. The fitting portion forms an upper hook (124). The upper hook is received in the slit and engages with the slant portion.
摘要:
A card connector (100) includes an insulative housing (10), a number of contacts (30) retained in the insulative housing, a metal shell (20) covering the insulative housing for defining a receiving space (60), and an ejector (50) assembled on the insulative housing. The ejector includes a cam portion (51) and a shaft (52) actuating the cam portion. The cam portion includes a pivoting portion (510), a first arm portion (511) and a second arm portion (512) respectively and angularly extending from the pivoting portion, and at least one positioning portion (513) extending from the pivoting portion along a vertical direction. At least one of the metal shell and the insulative housing defines a hole (19, 25) receiving the at least one positioning portion.
