Description

Electrical connector

[ technical field ] A method for producing a semiconductor device

The utility model relates to an electric connector especially relates to an electric connector who does benefit to high frequency signal transmission.

[ background ] A method for producing a semiconductor device

A "stub" is a branch circuit that is open at the end of a signal channel where it is undesirable in the transmission of high frequency signals because the signal energy propagating down the signal channel will split at the branch circuit such that some of the energy propagates down the stub, where it is reflected back into the signal channel where it mixes with, and even cancels, the desired signal, creating signal interference known as the "stub effect" which is highly detrimental to the transmission of high frequency signals.

For example, in the electrical connector disclosed in CN201720476493.5, before the docking element is inserted, the distance between the contact portions of the two rows of terminals is smaller than the thickness of the docking element, and after the docking element is inserted, the terminals can provide enough elastic force to abut against the docking element, but in order to guide the docking element to enter, a bending portion is further extended at the contact portion. After the terminal contacts with the butting element, the signal mainly propagates to the main body part through the contact part, the bent part is not in the set signal channel, but in the actual process, the signal still propagates to the bent part in a splitting way, and a short stub effect is generated.

In order to avoid this, in the electrical connector described in patent No. cn201710954866.x, the terminal contact portion is no longer extended with a bending portion for guiding, the terminal contact portion is directly disposed at the terminal end, and a signal is not split when passing through the terminal contact portion, but in order to prevent "kneeling pin", before the docking element is inserted, the distance between two rows of terminal contact portions of the electrical connector needs to be greater than the thickness of the docking element, when the electrical connector is in contact with the docking element, the terminal is not pressed by the docking element to deform, so that it is difficult to abut against the docking element by its own elastic force, the abutting pressure on the docking element is insufficient, and there is a moving space between the terminal and the sidewall of the insulating body, under the environment of impact or vibration, the electrical contact between the terminal and the docking element is not stable enough, and the electrical connector is prone to have a phenomenon of instantaneous power failure.

Therefore, there is a need for an electrical connector that overcomes the above problems.

As shown in fig. 3 and 4, before the mating component 6 is mated with the electrical connector 100, the connecting portion 31 is higher than the second sidewall 12 and abuts the insulating member 2 upward, the elastic component 3 provides an upward elastic force to the insulating member 2, and supports the insulating member 2 to keep the pressing portion 222 at a position higher than the contact portion 52, so that the pressing portion 222 does not contact the terminals 5 before the mating component 6 is inserted, the distance between two rows of the terminals 5 is greater than or equal to the thickness of the mating component 6, and the mating component 6 does not receive resistance when just inserted between two rows of the terminals 5.

In the process of inserting the abutting element 6 and the insulating member 2 into the insulating body 1, the abutting element 6 and the elastic arm 22 enter the accommodating cavity 13, and the conductive sheet 62 and the pressing portion 222 are in sliding contact with two opposite sides of the contact portion 52 respectively.

The process of inserting the mating element 6 into the electrical connector 100 is further explained below:

when the docking element 6 does not enter the docking cavity 13, the fastening portion 223 and the matching portion 114 are in a fixed state, and at this time, the operating portion 27 needs to be pulled to pull the insulating member 2 upward for a certain distance, so that the fastening portion 223 is separated from the matching portion 114. Since the connecting portion 31 is higher than the second sidewall 12 and abuts the insulating member 2 upwards, the elastic element 3 provides the insulating member 2 with an upward elastic force, and as shown in fig. 4, after the force is no longer applied to the insulating member 2, the elastic element 3 supports the insulating member 2 and keeps the pressing portion 222 higher than the contact portion 52.

As shown in fig. 5, when the abutting element 6 passes through the abutting cavity 26 and enters the receiving cavity 13, the protrusion 61 abuts against the boss 251, and the abutting element 6 pushes the insulating member 2 to move together, in this process, because the distance S1 between the abutting surface 611 and the pressing portion 222 in the vertical direction is smaller than the distance S2 between the abutting surface 611 and the conductive sheet 62 in the vertical direction, the abutting element 6 contacts the contact portion 52 first.

As shown in fig. 5 and 6, the abutting element 6 is inserted continuously, and the pressing portion 222 starts to press the terminal 5, so that the contact portion 52 is electrically contacted with the abutting element 6. The pressing part 222 slides on the contact part 52, the contact part 52 slides on the conductive sheet 62, and the sliding of the pressing part 222 and the contact part 52 is not hindered because the contact part 52 and the conductive sheet 62 are flat plates. In the inserting process, the first side wall 11 gives a third acting force F3 to the buckling portion 223 to point to the abutting element 6, the abutting element 6 presses the contact portion 52 to give a second acting force F2 to the contact portion 52 and the pressing portion 222 to point to the adjacent first side wall 11, the second acting force F2 and the third acting force F3 which are opposite in direction and applied above the elastic arm 22 can enable the abutting portion 23 to abut against the abutting element 6, the abutting element 6 gives a first acting force F1 to the abutting portion 23 to point to the third side wall 21, and the three acting forces enable the insulating member 2 to be tightly attached to the abutting element 6 while keeping the insulating member 2 balanced.

As shown in fig. 6, after the docking element 6 is inserted to a certain position, the locking portion 223 is fixed to the engaging portion 114, at this time, the insulator 2 abuts against the second sidewall 12, the partition 112 abuts against the third sidewall 21, and neither the insulator 2 nor the docking element 6 can move downward.

3.
