【Detailed ways】

Please refer to Fig. 3, the utility model is made by stamping a sheet metal, including: a first row of continuous terminals 50 and a second row of continuous terminals 60, wherein:

The first row of continuous terminals 50 is provided with a plurality of first terminals 51 and a first strip 52, and the first terminal 51 is linearly extended from one end to the other end and is sequentially provided with a pin portion 53, a middle portion 54, a The extension portion 55 and a contact portion 56 have a contact point 57 protruding from the surface of the contact portion 56 . The leg portion 53 of each first terminal 51 is connected to the first strip 52 and arranged at equal intervals.

The second row of continuous terminals 60 is provided with a plurality of second terminals 61 and a second strip 62. The second terminal 61 is linearly extended from one end to the other end and is provided with a pin portion 63, a middle portion 64, a The extension part 65 and a contact part 66, the contact part 66 is provided with a protruding contact point 67, the pin part 63 of each second terminal 61 is connected with the second strip 62 and arranged at equal intervals, the first terminal 51 and the second terminal 61 have the same shape.

The second row of continuous terminals 60 is inserted into the terminal gap of the first row of continuous terminals 50 by the pair of contact parts 66, so that the first and second strips 52, 62 are located at the two ends of the first and second terminals 51, 61 respectively; The utility model is characterized in that the contact portion 56 of the first terminal 51 is connected to the second strip 62, and the contact portion 66 of the second terminal 61 is connected to the first strip 52, so that the first and second terminals 51, 61 The two ends of both are connected by the first and second material strips 52, 62, which can be very stable. In addition, the contact portion 56 of the first terminal 50 is located inside the pin portion 63 of the second terminal 60, and the second terminal The contact portion 66 of 60 is located inside the pin portion 53 of the first terminal 50, so that two rows of continuous terminals connected together can be processed at one time in electroplating without first being separated and then electroplated.

Please refer to Fig. 4, when the plastic seat body of the electrical connector is to be assembled after the electroplating is completed, the first and second rows of continuous terminals 50, 60 need to be separated first, and at this time, the contact portion 56 of each first terminal 51 is connected to the second row. The joint of the strip 62 is cut and at the same time the contact portion 56 is pressed up to form an upward overflow pressure, and the contact portion 66 of each second terminal 61 is also cut at the junction of the first strip 52 and the contact portion is simultaneously cut. 66 is pressed down to form a downward overflow pressure, so that the first and second rows of continuous terminals 50, 60 are separated; please refer to Figure 5, and then the first and second row of continuous terminals 50, 60 are pulled apart; please refer to Figure 6 , the middle portion 54 of each first terminal 51 of the first row of continuous terminals 50 is bent by 90 degrees, and the middle portion 64 of each second terminal 61 of the second row of continuous terminals 60 is also bent by 90 degrees.
