Problems solved by technology
[0003] Since the terminals are fixed by pins, the insulating shell needs to have sufficient thickness for the barbs of the terminals to interfere and fix, so that the overall height of this type of card edge connector is high, which cannot meet the market demand for thinning
Moreover, if the thickness of the insulating case is reduced in order to meet the demand for thinning, it is easy to be pierced by the barb of the terminal due to the insufficient thickness of the insulating case.
When the barb of the terminal pierces the insulating shell, it will cause the insulating shell to warp or even break, and at the same time, the coplanarity of each row of terminals will become poor, which is not conducive to soldering and fixing on the circuit board

A card edge connector comprises an insulating shell, a plurality of first terminals and at least one terminal block. The insulating shell is provided with a first wall and a second wall which are opposite to each other, a slot arranged between the first wall and the second wall, and a plurality of first terminal grooves spaced apart from each other and arranged in a row on the first wall. The first terminal grooves are respectively communicated with the slot. The first terminals are fixedly arranged on the first wall and are respectively disposed in the first terminal grooves. Each terminal block includes an insulating body combined with the second wall, and a plurality of second terminals spaced apart from each other and arranged in a row on the insulating body. Each second terminal includes a fixed part fixedly arranged on the insulating body, a contact part extending out of the insulating body and extending into the slot, and a tail part extending out of the insulating part.
Description
technical field [0001] The invention relates to a card edge connector. Background technique [0002] Generally, the card edge connector is used to set on a circuit board for an electronic card to be plugged in. It has an insulating shell with a longitudinal slot in the middle, and two rows of insulating shells respectively fixed on the insulating shell and located on both sides of the slot. terminals. Usually, the terminals are mounted on the insulating shell in the form of pins, such as disclosed in Taiwan Patent TWI303117. [0003] Since the terminals are fixed by means of pins, the insulating shell needs to have sufficient thickness for the barbs of the terminals to be fixed by interference, so that the overall height of this type of card edge connector is high, which cannot meet the market demand for thinning. Moreover, if the thickness of the insulating case is reduced in order to meet the demand for thinning, it is easy to be pierced by the barbs of the terminals due...
