Description

Card edge connector

The present invention relates to a card edge connector, and more particularly to a card edge connector having a plate firmware.

Please refer to Chinese Patent No. 200410065627.1 for a card edge connector having an insulating body, an insulating arm extending forward from the longitudinal ends of the insulating body, and a conductive terminal received in the insulating body. . The end of the insulating arm is provided with a guiding portion and a buckle portion to provide a guiding action and a buckle function respectively when the electronic card module is inserted. Because the strength of the insulating arm is insufficient, the outer portion of the insulating arm is also provided with a metal member to enhance the strength of the insulating arm. The metal member includes an elongated body coated on the insulating arm and a guiding piece and a reinforcing piece formed by bending inward from the upper edge of the body and cooperating with the guiding portion and the buckle portion, and the lower edge of the body is further downward The bend extends to form a welded portion. Due to the large number of conductive terminals, a large amount of heat is generated when the card edge connector is soldered to the circuit board, which may cause distortion of the insulating body, so that there may be an empty soldering phenomenon when the soldering portion of the metal member is finally welded. .

Therefore, it is desirable to design a new type of card edge connector to improve the above problems.

The main purpose of this creation is to provide a card edge connector that improves the soldering condition of the board firmware.

In order to achieve the above object, the present invention adopts the following technical solution: a card edge connector including a base, a conductive terminal, a lock arm and a plate fastener; the base is provided with a card receiving groove extending forwardly through the front end surface thereof The end of the two ends of the base, the conductive terminal includes a card contact portion extending into the card receiving slot and a board connecting portion extending from the base, the latch arm includes a plastic arm and a metal arm extending forward from the end portion respectively The metal arm includes a holding portion fixed at the end portion and a main body portion attached to the plastic arm, the plate firmware includes a fixing portion and a plate connecting portion; and one of the fixing portion of the main body portion of the metal arm and the plate fastener is provided with a fixing hole The other one is provided with a tab, and the tab is received in the fixing hole. The size of the fixing hole is larger than the tab so that the tab performs a certain range of movement in the fixing hole.

Compared with the prior art, the present invention has at least the following effects: the metal arm of the board and the lock arm is matched with the fixing hole by the cooperation of the tab and the fixing hole, thereby realizing the slight floating function of the board firmware and simplifying the process.

The fifth figure is a perspective view of another angle of the metal arm and the plate fastener shown in the fourth figure.

Referring to the first figure, the present card edge connector 100 includes a base 11 made of an insulating material, a conductive terminal held by the insulating body, the lock arm 3 and the plate fastener 4. The base 11 is provided with a card receiving slot 111 extending forwardly through the front end surface 110. The card receiving slot is defined by two upper and lower sidewalls. The conductive terminal is a conventional technology, and the drawing is not shown. The conductive terminal includes the setting. An upper row of terminals on the upper side wall and a lower row of terminals disposed on the lower side wall, each of the conductive terminals includes an elastic card contact portion extending into the card receiving slot 111 and a board connecting portion extending from the base, the board connecting portion being used for soldering the circuit board. Ends 12 are provided at both ends of the base 11. The present card edge connector has a high configuration and the end portion 12 has an extension 121 that projects forwardly from the base front end face 110.

Referring to the second to fifth figures, the lock arm 3 includes a plastic arm 31 and a metal arm 32 extending forward from the end portion 12, respectively. The front end of the plastic arm 31 is provided with a card pressing portion 311 (refer to the first figure). A slit 312 is formed between the extending portion 121 and the plastic arm 31, and the end portion is provided with a fixing slit (not shown) on the inner side of the slit. The metal arm 32 includes a holding portion 321 fixed to the end portion and a main body portion 322 attached to the plastic arm, and the holding portion is fixed to the fixed slit by the barb 3211.

The plate firmware 4 includes a fixing portion 41 and a plate connecting portion 42, and the fixing portion 41 of the plate fastener 4 is inserted into the slit 312. One of the main body portion 322 of the metal arm of the present invention and the fixing portion 41 of the plate fastener is provided with a fixing hole 323, and the other is provided with a protruding piece 411. The protruding piece 411 is received in the fixing hole 323, and the fixing hole 323 is larger in size than the convex portion 323. The sheet 411 causes the tab 411 to perform a certain range of movement in the fixing hole 323, so that the floating structure can be simplified as much as possible in addition to the function of slightly floating the panel firmware 4. In a specific embodiment, the fixing hole 323 is provided in the main body portion 322 of the metal arm, the tab 411 is disposed on the fixing portion 41 of the plate fastener, and the plate fastener 4 is attached to the outside of the main body portion 322 of the metal arm. When the electronic card is inserted and rotated downward, the metal arm 32 moves laterally with the front end of the holding portion 321 as a supporting point, the fixing portion 41 of the plate fastener is vertical, and the fixing hole 323 is disposed at a fixing portion adjacent to the metal arm. At 41, this facilitates the fixing of the board firmware, and even if the lock arm 3 moves, the influence on the board firmware 4 is small. The tab 411 is formed inwardly from the fixing portion 41, and the tab 411 is inclined downward inwardly and then received in the fixing hole 323 in such a manner that the floating structure can be simplified as much as possible. Each of the metal arms 32 is provided with two fixing holes 323 arranged in the front-rear direction, and each fixing portion 41 is provided with two tabs 411 for contributing to the balance of forces in the front-rear direction, and the fixing portion 41 of the plate fastener 4 The slit 312 is inserted such that the outer side of the fixing portion 41 blocks the extending portion 121, reducing the possibility that the plate member is detached. The fixing portion 41 of the plate fastener and the plate connecting portion 42 are connected by an inverted L-shaped connecting portion 43, and the connecting portion 43 extends first outward from the fixing portion 41 and extends vertically. The metal arm of the present invention is assembled from the front to the rear, and the plate fastener is assembled from the bottom to the top, so that the metal arm and the plate fastener are assembled and fixed to the end in mutually perpendicular directions.

The metal arm 32 is also provided with laterally bent resisting ears 324 which are located outside the fixed portion 41 and spaced apart by a predetermined distance to prevent the latching arm 3 from excessively moving outward. The metal arm 32 is disposed at the other edge of the opposite abutting ear 324 to extend horizontally against the anti-sliding ear 325. If the electronic card is not inserted, the anti-slipping ear 325 can prevent the electronic card from being pressed down, thereby allowing the user to understand .

In summary, this creation is in line with the new patent requirements, and the patent application is filed according to law. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited to the above embodiments, and those who are familiar with the skill of the present invention are equivalent to the equivalent modifications or changes made by the spirit of the present creation.
