    摘要: An electrical connector (1) includes an insulative housing (10) and a number of contacts (20). The insulative housing defines a mating space (13), a number of passageways (114) communicating with the mating space, and a number of bar portions (117) each in one passageway. Each contact has a body portion (21) received in a corresponding passageway and exposed into the mating space, and a solder portion (22) extending from the body portion. The body portion defines a recess (214) receiving a corresponding bar portion for ensuring the body portion snugly abutting against the inner face of the corresponding passageway.

    摘要: An electrical connector (1) includes an insulative housing (2) and a number of contacts (3). The insulative housing defines a mating space (23), a number of passageways (220) communicating with the mating space and a number of recesses (221). Each recess communicates with a corresponding passageway and a projection (222) is formed between the recess and the corresponding passageway. The contacts are received in the passageways and each has a hook portion (34) clasping a corresponding projection for preventing the contact from moving into the mating space.

    摘要: An electrical connector assembly for connecting one printed circuit board to another printed circuit board comprises a first connector (1) and a second connector (2). The first connector includes a first insulative housing (10) and a number of first terminals (11). The first insulative housing has an elongate central island (103) with a recess (104) therein, and comprising a number of apertures (101). The first terminals are received in corresponding apertures. The second connector includes a second insulative housing (20) and a number of second terminals (21). The second insulative housing has a tongue portion (201) mating with the recess of the first housing. When the first connector mates with the second connector, the second terminals electrically connect with the first terminals by extending into the apertures respectively.

    摘要: Cursive Chinese characters are analyzed using a semantic matching process whereby radicals within the character are first extracted and used to reduce the search space of the full lexicon to only those characters containing the matching radical. In performing the radical extraction, the input character is normalized and segmented into strokes that are in turn organized based on stroke up/down information and local maxima and minima information. Obscure breakpoints and connecting strokes are removed in the process. Dynamic program matching is then performed on a stroke basis in which stroke substitution costs are assessed on a point-by-point basis through a variety of techniques, including tangent vector analysis, center relationship assessment and starting point/ending point assessment. Dynamic programming costs are normalized based on the length of the reference radical and location dissimilarities are removed.
