The specific implementation mode is as follows:

the present invention will be described in detail below with reference to the accompanying drawings and specific preferred embodiments so that the advantages and features of the present invention can be more readily understood by those skilled in the art, and these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

Embodiment 1, as shown in fig. 1 to 3, a small-sized waterproof aviation plug convenient to process includes a plurality of terminals 10, a welding piece 11 is formed at the rear end of each terminal 10, all the terminals 10 are inserted into corresponding insertion holes 21 in the middle of a plastic positioning block 20, and the outer side wall of the middle of each terminal 10 is clamped on the inner side wall of each insertion hole 21;

the rear end of the terminal 10 extends out of the rear wall surface of the plastic positioning block 20.

Furthermore, four insertion holes 21 are formed in the middle of the plastic positioning block 20, and the four terminals 10 are inserted into the corresponding insertion holes 21.

Further, a radially extending edge 22 is formed on the outer side wall of the plastic positioning block 20.

Furthermore, the plastic positioning block 20 has an extension 23 formed at the front end thereof and extending forward, a front insertion hole 24 formed at the middle of the front end surface of the extension 23, and the front end of the terminal 10 is inserted into the corresponding front insertion hole 24.

Further, the front insertion hole 24 is a stepped through hole, and a small-diameter hole section 241 having a smaller diameter than the rear end is formed at the front end thereof.

Further, a cross-shaped supporting block 25 is formed in the middle of the rear wall surface of the plastic positioning block 20, and the rear end welding pieces 11 of the four terminals 10 are inserted into four slots of the cross-shaped supporting block 25. It is used as a female plug.

In embodiment 2, the front ends of the four terminals 10 extend out of the front end face of the plastic positioning block 20. The rest is the same as example 1. It is used as a male plug.

In this embodiment, it is earlier with four terminals 10 card put in four jacks 21 to guarantee that the front end of four terminals 10 aligns, the rear end stretches out the rear end face of jack 21, then, can with its with cable conductor 100 be connected electric wire end welded fastening can, then, it can with injection moulding.

It is through installing terminal 10 on plastics locating piece 20 for the front end of terminal 10 all aligns, and the rigidity makes things convenient for follow-up injection moulding, and it has increased the intensity of terminal 10 department moreover, guarantees moreover that can not squint between the terminal 10, improves processingquality.
