Abstract: An electrical connector includes an insulative housing (10) defining a passageway (11) therein, a power contact (20) received in the passageway and a fastening member (28) for mating with the power contact. The power contact includes a pair of contacting portions (21) and a connecting portion (22) connecting the pair of contacting portions. The pair of contacting portions is essentially parallel to each other and a spacing (210) is defined therebetween. The connecting portion includes a fastening portion (23) essentially perpendicular to the pair of contacting portions. The fastening member (28) is separately made from the power contact to fasten securely to the fastening portion (23). Thus, the power contact can be reliably fixed in the insulative housing.

Abstract: A power connector includes an insulative housing, a power contact retained in the insulative housing, a locking member formed on the insulative housing and a key member. The key member includes a retaining portion fixed in the insulative housing and a protrusion extending along a lengthwise direction of the insulative housing. The locking member locks the key member in a mounting hole of the insulative housing. The locking member includes a locking arm. The locking arm is accessible from outside of the insulative housing to thereby release the key member from the insulative housing.

Abstract: A power connector includes an insulative housing, a power contact retained in the insulative housing and a key member. The insulative housing defines a receiving chamber recessed from a mating face and a rear portion located at the rear of the receiving chamber. The rear portion defines a mounting hole in communication with the receiving chamber and a first locking arm having a first hook protruding into the mounting hole. The first hook is lockable with the key member in order to prevent the key member from withdrawing from the mounting hole. The key member further defines a slit through which the first hook is forwardly exposed to an exterior. As a result, a tool can be inserted into the slit to push the first hook so as to unlock the first locking arm with the key member.
