The second row of continuous terminals is two rows of continuous terminals that are inserted in the terminal pitch of the first row of continuous terminals and arranged crosswise, so the material can be doubled in manufacturing, and the adjacent second row of terminals is separated by the intermediate strip. The first and second terminals are connected to each other, so that the overall two rows of continuous terminals are very stable and easier to punch.

2. The two rows of continuous terminals completed by stamping are also relatively stable in the process of being transported to the electroplating factory, and due to the connection of the intermediate strip, two rows of continuous terminals can be electroplated at one time, and the processing efficiency is doubled. Due to the contact of the first terminal The coordinates of the contact portion of the second terminal and the pin portion of the second terminal in the extension direction are staggered and do not overlap, and the coordinates of the contact portion of the second terminal and the pin portion of the first terminal are staggered and do not overlap, so it is easy for the first , The pins of the second terminal are tin-plated and the contact parts of the first and second terminals are gold-plated, so that gold plating and tin plating will not interfere with each other.

【Detailed ways】

The above and other purposes, advantages and characteristics of the present utility model can be more clearly understood from the detailed description of the following preferred embodiments and with reference to the drawings, wherein:

Please refer to Fig. 1 and Fig. 2, the utility model is made by stamping a sheet metal, including: a first row of continuous terminals 20, a second row of continuous terminals 30, wherein:

The first row of continuous terminals 20 is provided with a plurality of first terminals 21 and a first strip 22. The first terminal 21 extends linearly from one end to the other end and is sequentially provided with a pin portion 23 (indicated by a slash), a The middle part 24 and an elastic part 25, the plate surface of the elastic part is pierced and protruded with a contact part 26, and the pin part 23 of each first terminal 21 is connected with the first strip 22 at equal intervals arrangement.

The second row of continuous terminals 30 is provided with a plurality of second terminals 31 and a second strip 32. The second terminal extends linearly from one end to the other end and is provided with a pin portion 33 (indicated by a slash), a middle part 34 and an elastic part 35, the elastic part 35 is provided with a protruding contact part 36, the pin part 33 of each second terminal 31 is connected with the second strip 32 and arranged at equal intervals, the first The shapes of the first terminal 21 and the second terminal 31 are the same.

The second row of continuous terminals 30 is inserted into the terminal gap of the first row of continuous terminals 20 by the elastic part 35, so that the first and second strips 22, 32 are located at the two ends of the first and second terminals 21, 31 respectively. , and the coordinates of the contact portion 26 of the first terminal 21 and the pin portion 33 of the second terminal 31 in the extension direction are staggered and do not overlap, the contact portion 36 of the second terminal 31 and the pin portion of the first terminal 21 23 coordinates in the extension direction are staggered and do not overlap.
