  • Patent number: 7980865
    Abstract: A separable electrical connection may be provided with a landside pad on one of two electrical components to be joined. The landside pad may be made up of two parts, including a flat portion and a raised edge formed on the flat portion. In some embodiments, the raised edge may have a closed geometric shape. Then, a socket contact engaging the junction between the flat portion and the raised edge is prevented from sliding off of the landside pad by the raised edge. In addition, dual areas of electrical connection can be established between both the flat portion and raised edge of the landside pad and the correspondingly shaped pair of portions on the socket. This increases the electrical efficiency of the connection and its security.

    Abstract: An electrical element is revealed. At least one receiving hole disposes on an insulating body. A conductive layer disposes on surfaces of the receiving hole. At least one soldering body mounts in the receiving hole correspondingly and contacts with the conductive layer. Part of the soldering body exposes outside a surface of the insulating body to form a soldering part. The electrical element is further arranged with at least one conductive terminal mounted in the corresponding receiving hole movably and slantingly, the conductive terminal contacts with the conductive layer. Each conductive terminal includes a head part exposed outside the surface of the insulating body for being pressed and contacted. By electrical connection of the conductive layer, the assembly between the soldering body and the terminal is replaced and errors of the assembly between the soldering body and the terminal are eliminated.

  • Patent number: 7785114
    Abstract: Modification of the connections between a die package and a system board is described. In one example a pattern redistribution module is used in a socket. The module has a first array of contacts on one side of the module. The contacts have a first configuration to connect to the socket. A second array of contacts is on another side of the module opposite the first array of contacts and has a second configuration to connect to a package containing a die. A board is between the first and the second array of contacts to interconnect contacts of the first array of contacts to contacts of the second array of contacts.

  • Patent number: 7775803
    Abstract: The present invention provides an electrical connector comprising an insulative housing having a plurality of passageways, and a plurality of contacts received in the passageways, respectively. The passageways each defines two inner walls opposite to each other, the two inner walls each having at least one first retention device. The contacts each include a base, an upper arm extending from one side of the base and a lower arm extending from another side. The upper arm further defines two protrusions on opposite sides thereof and the lower arm defines two protrusions on opposite sides thereof. In assembly, protrusions on upper arm are located above the first retention device of the passageways, and protrusions on the lower arm are located below the first retention device of the passageways such that movement of the contact in the passageway along length axis of the passageway is limited in a predetermined distance.

  • Publication number: 20100197152
    Abstract: A simple structure socket 10 for connecting a ball grid array integrated circuit device to a test circuit has a base 14, contacts 26 arranged corresponding to the ball grid array, a nest assembly 16 of two comb structures 70 and a lever assembly 18 for spacing opposed tip portions of each contact away from each other to define a gap for receiving a ball. The lever assembly has two rectangular frames 86 each made of a distal cross piece 94, a proximal cross piece and two side pieces connecting the distal and proximal cross pieces. The two rectangular frames are arranged so that the side pieces are intersected at substantially mid portions thereof. This allows that, by depressing the proximal cross pieces toward the base, the distal cross pieces forces the comb structures toward each other.
