Electrical connector

The present invention relates to an electrical connector, and more particularly to an electrical connector that can simultaneously be inserted into two electronic cards.

With the development of wireless communication technology, mobile phones have developed models that can simultaneously read two user identification cards (SIM cards). Since the SIM card needs to be electrically connected to the circuit board through the electrical connector, in order to meet the electrical connector that can simultaneously insert two SIM cards and reduce the board area, a stacked SIM card connector is generated, for example, Taiwan. The new patent publication No. M324877 (corresponding to the Chinese mainland patent CN201081824) is disclosed.

In the electrical connector disclosed in the foregoing patent, the first insulative housing combined with the second insulative housing and the second insulative housing and the shielding housing form two card spaces respectively located on the upper and lower layers. However, since the second insulating body in the lower layer has a large area, when the electrical connector is reflow-bonded to the circuit board, warpage is easily generated by heat to lower the overall coplanarity. Furthermore, since the second insulating body is heated more than the first insulating body during the reflow process, the second insulating body is warped more than the first insulating body, thereby causing the combination of the two to be tight and affecting each other after reflowing. The warpage and coplanarity of each other cause unstable quality. In addition, it is obvious The design of the second insulative body itself is also complicated, requiring more material and process costs.

Accordingly, it is an object of the present invention to provide an electrical connector that can reduce warpage and that is easier to manufacture and that can be inserted into two electronic cards.

The part 71 is separated. Referring to Figures 9 and 10, a needle 8 can be inserted into the through hole 127 to activate the switch unit 7. When the needle 8 enters through the through hole 127, the push portion 721 is pushed and the connecting portion 724 and the contact portion 722 are interlocked, so that the contact portion 722 comes into contact with the abutting portion 71. That is, the elastic terminal 72 can be changed in contact with the abutting portion 71 by the needle 8 to be in contact with each other, and the embodiment is changed from a state in which it does not contact each other to a state in which it contacts each other. Thereby, the switch unit 7 can be caused to generate a signal to start a preset job. For example, the switch unit 7 is used as a reset switch, and after the needle 8 is touched, the circuit system of the electronic device (not shown) provided with the electrical connector 100 can be reset. In this way, by integrating the switch unit 7 in the electrical connector 100, the space occupied by the switch device and the manufacturing cost can be greatly reduced as compared with the conventional provision of a switch device (not shown).

The hole 127 extends obliquely upward, and the contact portion 722 extends directly from the end of the pushed portion 721 without being connected by the connecting portion 724 and is in contact with the abutting portion 71 in a normal state. Referring to FIGS. 14 and 15, after the needle 8 is inserted through the through hole 127, the push portion 721 is pushed and the contact portion 722 is interlocked to separate the contact portion 722 from the abutment portion 71. Thereby, the contact state of the contact portion 722 and the abutting portion 71 can also be changed, in which the state of being in contact with each other becomes a state of not contacting each other, and the effect of causing the switch unit 7 to generate a signal to start the preset operation can also be achieved. .

In summary, the terminal block 4 is disposed in the accommodating space 102 formed by the insulating case 1 and the shielding case 3 to form the second card slot 103, so that the structure of the insulating plate 41 can be simplified and the area can be reduced, and the insulating board can be made.

Furthermore, the insulating plate 41 has a simple overall structure and is easy to manufacture, and can simplify the cost of materials and processes. In addition, the switch unit 7 In the electrical connector 100, the space occupied by the switching device and the manufacturing cost can be greatly saved compared to the conventional provision of the switching device. Moreover, when the electrical connector 100 is assembled in an electronic device such as a mobile phone, once the mobile phone is down, the user does not need to open the mobile phone, and the pin 8 is directly inserted into the through hole 127 from the outside of the casing to touch the switch unit 7. A reset function that restarts the phone is reached.

However, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made in accordance with the scope of the present patent application and the contents of the patent specification, All remain within the scope of this new patent.
