Detailed ways

Please refer to Fig. 1, Fig. 2, Fig. 3, Fig. 4, and Fig. 5, the electrical connector of the present invention includes: the first base body 10, the second base body 25 and the positive position structure, wherein:

A plurality of terminals 12 are provided on the first seat body 10, and the first seat body 10 is provided with a connecting portion 13, and extension portions 14 and side arms 15 are arranged on both sides of the connecting portion 13, and the connecting portion 13 and the two side arms 15 surround Forming an accommodating area 16 , the terminal 12 is provided with a horizontal board portion 18 for connecting to the printed circuit board 24 .

A plurality of terminals 27 are provided on the second base body 25, and the second base body 26 is located in the accommodating area 16 of the first base body 10, and the plurality of terminals 27 are provided with horizontal connecting board portions 28 for connecting to the printed circuit board twenty four.

The positive position structure is arranged on the first seat body 10 and the second seat body 25, so that when the second seat body 25 is set in the accommodating area 16 of the first seat body 10, it can be positioned front, rear, left and right and can only float up and down. The positive position structure includes There are: a groove 41, located on the inner edge of the extension part 14 on both sides of the first seat body; a protrusion 42, located on the two side edges of the second seat body 25; the protrusion 42 of the second seat body and the first seat body The groove 41 of the seat body is locked, so that the front, rear, left, and right sides are locked and can only float up and down, and an elastic hook 43, which is arranged on the inner edge of the extension part 14 on both sides of the first seat body and can be hooked Fitting with the second base body 26 , the first base body 10 and the second base body 25 can be snapped together after being combined to achieve a more reliable positioning effect.

With the above structure, when assembling, the protrusions 42 on both sides of the second seat 25 are aligned with the grooves 41 of the first seat 10 and then inserted into the accommodating area 16 of the first seat 10 from top to bottom, At this time, the elastic hooks 43 on the inner edge of the extension portion 14 on both sides of the first base body are fastened to the second base body 25 .

The present invention can summarize following advantage, namely:

Although the number of terminals after the combination of the first and second base bodies 10, 25 is more, because the first and second base bodies 10, 25 can float up and down mutually, they can be adjusted up and down mutually to achieve the difference between the terminals on the two base bodies. The board-connecting portion is easy to form a coplanar surface, so that it can have a better soldering effect with the printed circuit board.

Because the first seat body 10 both sides is provided with side arm 15 and forms a very big space (reccommodating area 16) between two side arms, the second seat body 25 is set in this space, can make good use of this surplus space fully, this The connecting portion 13 of the first base body 10 is higher than the height of the second base body 25 (see FIG. 4 ), so it will not be hindered by the second base body 25 at the front end.

Since the first and second bases 10, 25 can float up and down with each other, even if the dimensions of the two bases have a slight error, through the mutual floating adjustment, the connecting plate parts of the terminals of the two after assembly are easy to meet the requirement of coplanarity, so The requirement for manufacturing precision can be reduced, so that the processing is easy and the manufacturing cost is greatly reduced. In addition, the first and second bases 10 and 25 can be arranged on the printed circuit board at one time after being assembled in the correct position, thereby reducing the processing cost.
