Description of reference numerals: the structure comprises an insulating shell 1, a plug hole 11, a circular hole 111, a square hole 112, a fixing groove 12, a recess 13, an upper-layer terminal 2a, a lower-layer terminal 2b, a mounting part 21, a pin 22, a convex hull 221, a pin 23 and a convex hull 24.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1-5, the multi-pin electrical connector in this embodiment includes an insulating housing 1, the insulating housing 1 is preferably made of plastic, and further includes two rows of terminals, each row of terminals has a plurality of terminals, and the two rows of terminals are arranged in an upper layer and a lower layer, so that the electrical connector is more compact in structure.

As shown in fig. 3, the terminal is an integrated structure, and includes a mounting portion 21, a pin 22 and a lead 23, wherein the pin 22 extends forward from the mounting portion 21 and is disposed at an outer end capable of being plugged; the pins 23 extend backwards from the mounting portion 21 and are used for welding a circuit board, the insertion hole 11 is formed in the insulating housing 1, the terminals are inserted into the insertion hole 11, the front sections of the insertion holes 11 are used for containing the pins 22 of the fixed terminals, the pins 22 protrude from the insertion holes 11, the rear sections of the insertion holes are used for containing the mounting portion 21, the terminals are integrally fixed, the pins 23 of the terminals are bent downwards from the end portions and are finally guided to the bottom surface of the insulating housing 1, specifically, the bending length of the upper-layer terminals 2a is long, the bending length of the lower-layer terminals 2b is short, and finally, the pins are landed on the same plane to form welding pin portions with approximately equal lengths, so that the electric connector is convenient to fix the board end, and the lower-layer terminals 2b and the upper-layer terminals 2a are staggered to avoid being connected in series.

The electric connector of many pins that this embodiment disclosed adopts the layer to arrange the structure and reduce whole volume, improves the compactness.

The manufacturing method of the electric connector with the structure is also disclosed, firstly, the insulating shell 1 with the plug hole 11 is formed by the existing method, and a flat flitch surface is formed on the ground; the rows of upper layer terminals 2a and lower layer terminals 2b as shown in fig. 6 are manufactured by blanking and bending; the insulating shell 1 and the rows of terminals are directly spliced and assembled, and finally the excess materials are cut off.
