When the electronic card is actually used, the electronic card is inserted into the insertion groove 5 through the insertion opening of the insertion groove 5, when the electronic card is inserted into the insertion groove 5, the outer surface 13 of the electronic card contacts the first elastic part 6, so that the first detection terminal 2 forms a grounding loop to complete the detection of the insertion of the electronic card; when the electronic card is inserted continuously, the electronic card presses the first elastic part 6, so that the first elastic part 6 contacts and conducts the adapting part 9 of the second detection terminal 3; when the electronic card is completely inserted into the insertion slot 5, the golden finger of the electronic card contacts the second contact portion 8 first, and then the golden finger of the electronic card contacts the first contact portion 7, so that the second detection terminal 3 forms a grounding loop through the first detection terminal 2, detection of the electronic card inserted to a correct position is completed, dual-function detection is realized, and then power can be supplied to the electronic card.
Referring to fig. 1 to 3, in the present embodiment, the insulation body 1 includes a top wall 11, a back wall 12 connected to the top wall 11, and two side walls 13, when actually manufactured, the top wall 11, the back wall 12, and the two side walls 13 are formed by injection molding with the same injection mold, the two side walls 13 are spaced and arranged in parallel, two ends of the back wall 12 are respectively connected to the two side walls 13, the top wall 11, the back wall 12, and the two side walls 13 jointly enclose to form the inserting groove 5, the first contact portion 7 is located between the first elastic portion 6 and the back wall 12, and the second contact portion 8 is located between the first contact portion 7 and the first elastic portion 6.
The top wall 11 is provided with an accommodating groove 14 communicated with the inserting groove 5, the switching part 9 is accommodated in the accommodating groove 14, and the switching part 9 is positioned above the first elastic part 6; when the electronic card is inserted into the insertion slot 5, the outer surface 13 of the electronic card abuts against the first elastic portion 6, and with the continuous insertion of the electronic card, the electronic card pushes the first elastic portion 6 to move upward and abut against the adapting portion 9, so that the first elastic portion 6 is accommodated in the accommodating slot 14, thereby preventing the electronic card from being "stuck" because the first elastic portion 6 is always in the insertion slot 5, i.e. the electronic card cannot be normally inserted because the first elastic portion 6 is in the insertion slot 5.
In this embodiment, the accommodating groove 14 penetrates through the top wall 11 in the vertical direction, and when the first elastic portion 6 moves upward and abuts against the adapting portion 9, the adapting portion 9 can move upward together with the first elastic portion 6, so as to ensure that the insulating body 1 has a sufficient space for yielding.

The second detecting terminal 3 is provided with an elastic sheet 19 which protrudes into the insertion groove 5, the first contact part 7 is arranged on the elastic sheet 19, and after the electronic card is completely inserted into the insertion groove 5, the elasticity of the elastic sheet 19 is utilized to ensure that the electronic card can be fully contacted with the first contact part 7, so that the electronic card is prevented from breaking signal transmission due to vibration or accidental touch, and the use performance of the card connector is improved.
The number of the signal terminals 4 is multiple, the second contact parts 8 of the multiple signal terminals 4 are arranged in a row, and the second contact parts 8 of all the signal terminals 4 are positioned between the first elastic part 6 and the first contact part 7; when the electronic card is inserted into the inserting slot 5, the golden fingers of the electronic card are ensured to be contacted with the first contact part 7 after being conducted with the signal terminal 4, so that the waste of electric energy caused by supplying power to the electronic card too early is avoided. Preferably, the second contact portion 8 has elasticity, so that when the electronic card is completely inserted into the insertion slot 5, the elasticity of the second contact portion 8 ensures that the electronic card can be fully contacted with the signal terminal 4, thereby preventing the electronic card from breaking signal transmission due to vibration or accidental touch, and improving the usability of the card connector.
The first detecting terminal 2 and the second detecting terminal 3 are embedded and molded (also called injection Molding and integral Molding) in the insulating body 1, and compared with the case that the first detecting terminal 2 and the second detecting terminal 3 are assembled in the insulating body 1, the connection strength between the first detecting terminal 2 and the insulating body 1 and the connection strength between the second detecting terminal 3 and the insulating body 1 are improved, and the first detecting terminal 2 and the second detecting terminal 3 are prevented from being withdrawn from the insulating body 1 due to multiple plugging and unplugging of an electronic card.
