  • Patent number: 8414323
    Abstract: A power connector, adapted for electrically connecting a cable with a complementary connector, includes an insulative housing defining a number of passageways and a number of power contacts received in corresponding passageway. Each contact has a base section, a first contact section and a second contact section. The base section includes a bottom wall and a first side wall and a second side wall extending perpendicularly from the bottom wall. The first contact section includes a first contact arm and a second contact arm parallel to the first contact arm. The second contact section includes a third contact arm and a fourth contact arm parallel to the third contact arm.

  • Publication number: 20120252254
    Abstract: A power connector adapted for electrically connecting with a cable includes an insulative housing defining a number of passageways extending therethrough and a number of contacts received in corresponding passageways. A latching arm is formed in each passageway. Each contact has a base section, a contact section extending from the base section, a retention section extending oppositely from the base section, and a side section extending perpendicularly from edges of the base section. The base section of the contact defines a latching hole receiving the latching aim of the insulative housing to thereby secure the contact in the housing.

  • Patent number: 8251754
    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.

  • Publication number: 20120142227
    Abstract: A power connector includes an insulative housing, a number of contacts retained in the insulative housing and a spacer fixed to the insulative housing. The insulative housing includes a mating surface, an end surface opposite to the mating surface and a plurality of passageways extending through the mating and the end surfaces. A depression and a cavity are recessed into the insulative housing from the mating surface and the end surface, respectively. Each contact includes a main portion received in corresponding passageway and a tail portion located in the cavity in condition that at least one side wall of the tail portion is exposed to the air for excellent heat dissipation.

  • Patent number: 8070533
    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.
