An electrical connector includes a frame (2) defining a substantially rectangular configuration and header and rear portions (22), a cover (3) moveably disposed on the frame and including a supporting surface (31) with a plurality of holes (311) defined therein, a lever (4) having a cam portion (42) disposed on the rear portion of the frame to drive the cover to move from a first position to a second position, a base (1) disposed within the frame and under the cover and an engaging member (6) retained in one side of the frame. The engaging member defines an engaging portion (63) at one end thereof which can engage with the lever when the lever arrives at a vertical position relative to the base.

A contact includes a first contact pin, a second contact pin and a spring. The first contact pin comprises a wide portion for contacting and a narrow portion. The second contact pin comprises a holding portion and a guiding portion extending upwards from the holding portion. The guiding portion has a receiving space and a pair of channels, the narrow portion is received in the receiving space and has thereof a pair of projecting portions sliding in the channels. The spring is moveably seated on the holding portion and limited under the wide portion to allow the first contact pin to shift upwards and downwards therein.

A multi-channel display driver circuit incorporating modified D/A converters has a plurality of digital comparators connected to a number generator. Each digital comparator has an output, a digital data input and a reference input. The reference inputs of all digital comparators are connected to the number generator and the outputs are respectively connected to corresponding data channels of a display. By the proposed technique, each digital comparator obtains a unique non-sequence reference signal, and then compares it with the input digital data signal. Since the non-sequential signals are input to the reference input of the digital comparator, the overshoot distortion, the harmonic distortion and the electromagnetic interference problems are prevented. Therefore, the precise imaging can be obtained with this signal modulation technique in small circuit size.

An IC socket (2) includes a base (21), a cover (22) engaged upon the base and moveable along a front-to-back direction relative to the base, and a lever (23) for driving the cover to slide on the base. The lever includes a lateral rod (232) and a longitudinal rod (231) connected to the lateral rod, with the lateral rod defining an engagement section (233) adapted to engage the cover for urging the cover to move. The engagement section has a body of flexible material (234) thereon for preventing abrasion of a part of the cover associated with the engagement section and for eliminating damage caused by engagement abrasion.

In a power-saving control module for an electrical appliance that includes a DC power supply and a remote control receiver, a switch component serves to make or break electrical connection between an AC power source and the DC power supply, a diode provides a path for supply of a DC power output from the DC power supply to the remote control receiver when connection between the DC power supply and the AC power source is made, and a rechargeable power source provides DC power to the remote control receiver when connection between the DC power supply and the AC power source is broken. A driver is controlled by the remote control receiver so as to cause the switch component to make or break the electrical connection between the AC power source and the DC power supply.

An optical-fiber connector includes an insulative main body having a pair of optical components extending forwardly therefrom. Each optical component defines at least one lens and a guiding post located at outside of the lens. Each guiding post defines a through hole extend through the guiding post and the main body in a front-to-back direction and fulfilled with the air for transmitting a test light. The test light from the through hole of the guiding post acts as an accurate measuring reference of the true position between the lens and the fiber because of having no displacement of the light path through a through hole.
