A burning system includes an indentifying module, a dividing module, a calculating module, an index module, and a burning module. The identifying module identifies bad blocks of the flash memory. The dividing module reads all blocks of the flash memory in sequence, and when one or more continuous blocks being read are bad blocks, groups the bad blocks and the previously read good block as a storage sector. The calculating module calculates a bad block ratio of each storage sector. The index module assigns a priority level to each storage sector according to the bad block ratio of the storage sector, and associates each priority level of the storage sectors with a start address. The burning module accesses the storage sectors in an order of the priority levels of the storage sectors, and begins writing programs into the storage sectors from the associated start addresses.

An electrical card connector (100) includes an insulative housing (2, 4, 6) defining a number of passageways, a number of contacts (12) retained in the passageways and the insulative housing and a metal shield (3, 5, 7) covering the insulative housing. The insulative housing has a base portion (20, 40) and a pair of retaining portions (22, 42, 62) extending forwardly from the base portion. Each retaining portion defines a cavity (24, 44, 45, 63). The metal shield includes a main portion (30) and a number of lateral walls (31) for defining a card receiving room. The metal shield integrally forms a locking portion (34, 54, 55, 75) having a stamped portion (341, 543, 553, 751) therefrom. The stamped portion is received in the cavity to pre-loadingly engage with the retaining portion.

An electrical card connector comprises an insulative housing (10), a plurality of contacts (20) received in the housing, a shell (30) covering the housing and an ejector (500. The housing is located at the front of the shell. The ejector comprises a base (51) and an ejecting member (53) assembled on the base, the base is located at the side of the housing, and the ejecting member is moveably in a card inserting direction. The base is secured to the housing to limit a lateral movement of the base.

An electrical connector includes an insulative housing, a plurality of contacts retained in the housing, a shell enclosing the housing and a dust-proof device. The dust-proof device defining a dust-proof member movable from a closed position to an open position, a resilient connecting member attached to the dust-proof member, and a pivoting portion connecting the dust-proof member with the shell by a shaft formed on the resilient connecting member running through the pivoting portion. A peak point is provided on the pivoting portion and disposed between a first position and a second position, and the dust-proof member will automatically return to the closed position when the shaft rotates between the first position and the peak point and automatically reach to the open position when the shaft rotates between the peak point and the second position.
摘要:
A card connector includes an insulative housing having an elongated base and a pair of arms located at opposite sides of the base thereby defining a receiving cavity therebetween. Each arm defines a guiding slot extending along a rear-to-front direction and in communication with the receiving cavity. A plurality of contacts are retained in the base, each having a pin shaped contacting portion projecting into the receiving cavity and a solder portion extending out of the base. A shell device is attached to the insulative housing. Opposite sides of each guiding slot extend inwardly so as to form an adjustment section interconnecting with the base, which can ensure a card to be inserted accurately.Page 16 of 16
