Card edge connector

Abstract

The invention discloses a card edge connector, comprising an insulating body welded on a mother circuit board; wherein the insulating body is opened with a connecting slot for containing one end of sub circuit board, the insulating body is internally opened with a plurality of first and second row conductive terminal slots respectively containing a plurality of first and second row conductive terminals, the contact parts of the first and second row conductive terminals can be respectively contacted with the two surfaces at one end of the circuit board, the welding parts of the first and second row conductive terminals are all arranged at the rear of the insulating body and welded on the mother circuit board, the other end of the sub circuit board corresponding to one end of the sub circuit board is locked on an external mechanism in parallel, the insulating body is sunk into the mother circuit board, height is reduced, volume of product adopting the card edge connector is reduced, and the structure of the first and second row conductive terminals can avoid the defect that common card edge connector terminal is easy to be damaged.

Description

technical field [0001] The invention relates to a card edge connector for connecting a mother circuit board and a daughter circuit board, in particular to a card edge connector sunken between the mother circuit boards. Background technique [0002] In the existing card edge connector, the common structure is shown in Figure 9, which includes an insulator C, and the insulator C is provided with a plurality of first terminal slots C4 and a plurality of second terminal slots C6, the first terminal The slot C4 matches the first terminal D, and the second terminal slot C6 matches the second terminal E and is welded on the motherboard F. The welding parts of the first and second terminals D and E are respectively located on the left and right sides of the insulator. The notch of the insulator C has a first inclined surface C1, a second horizontal surface C2, a vertical surface C3, a third horizontal surface C5 and The fourth inclined surface C7 forms a card insertion method in wh...

Problems solved by technology

[0003] The disadvantage of this type of connector is that the product is too bulky and takes up too much space, which cannot adapt to the development of today's products in the direction of small size

In addition, as shown in Fig. 9, the fulcrum E1 of the force arm of the second terminal E is on the left side of the second terminal E. When the sub-board G is pulled out, the terminal contact part E2 interferes with the sub-board G, which may easily damage the terminal, and the sub-board G When inserting the card, the second terminal D is also easily damaged
