Abstract

The utility model relate to a stepped multicore circular-type aviation plug which is easy to weld. The aviation plug solves a problem that in metal pins and leads are not easy to weld in an aviation plug used in the prior art, and reduces phenomenon that a solder tip touches welding ends of other metal pins. The aviation plug comprises an insulation body and metal pins disposed inside the body. The body plug and a welding lead end of a plug seat are arranged as a stepped platform. The welding ends of the metal pins are fixed on the stepped platform. Notches of the welding ends of the metal pins are towards a direction which deviates from a stepped end face axis. The body plug and a welding lead end of a plug seat are provided with the stepped platform. The metal pins are fixed on the stepped platform. In a lead welding process, the metal pins distributed in the above structure are disposed in different layers of the stepped platforms. Thus, the densely distributed metal pins are hierarchically separated, so that in a manual welding process, the solder tip is not easy to touch the welding ends of other metal pins. In a repair welding process, leads which have been welded do not shield the welding ends of other metal pins, thereby reducing welding difficulty.

Description

The round aviation plug of staged multicore

Technical field

The utility model relates to a kind of aviation plug, especially relates to the round aviation plug of a kind of staged multicore.

Background technology

Aviation plug is a kind of quick plug that is used in the aviation, and along with development of electronic technology, the application of aviation plug in electronic equipment also more and more widely.Existing aviation plug; Lead-in wire generally adopts welding manner to be connected with metal ferrule; Need electric iron to carry out welding lead, and solder horn is difficult in intensive metal ferrule, carrying out welding lead, simultaneously aviation plug to labor claim than higher; Especially multicore aviation plug, the welding difficulty is bigger.

Summary of the invention

The utility model technical problem to be solved is in the existing technology; Being difficult for when adopting welding manner between metal ferrule in the aviation plug that uses and the lead-in wire; Its objective is to solve difficult, the inefficient problem of the welding that occurs in aviation plug and the operating process of socket welding lead, improve workman's efficient.

The technical scheme of the utility model is the round aviation plug of this a kind of staged multicore, and the welding lead end of the body plug and socket of described aviation plug is set to the ladder platform.

The ladder platform of the welding lead end of described aviation plug is divided into different end faces, and the number of end face comprises 2 above 2.

Described metal ferrule welding ends is fixed on the different end faces of ladder platform.

The welding ends breach of described metal ferrule is towards the direction that deviates from stairstepping end face axis.

Total number of described aviation plug metal ferrule is below 5; When comprising 5; Only need welding ends breach with metal ferrule towards the direction that deviates from the end face axis, welding lead end that need not the body plug and socket is set to the ladder platform, and total number of metal ferrule is at 5 when above; Not only will be with the welding ends breach of metal ferrule towards the direction that deviates from stairstepping end face axis, and the welding lead end of body plug and socket is set to the ladder platform.

The round aviation plug of a kind of staged multicore with above-mentioned feature structure has following advantage:

1. the welding lead end of this kind aviation plug and socket adopts stepped design, makes intensive metal ferrule distribute to become and has levels more, just can conveniently weld, and has improved welding efficiency.2. in this kind aviation plug when welding,, flatiron is prone to stretch into welds first watch, is difficult for touching other metal ferrule welding ends, reduces the probability of damaged member, increases the validity of welding.3. the breach of this kind aviation plug metal ferrule welding ends is placed towards the direction that deviates from stairstepping end face axis, and when carrying out repair welding, the lead-in wire that welding is accomplished can not block other metal ferrule welding ends, convenient welding.

Embodiment

Can know to structure shown in Figure 4 by Fig. 1; The round aviation plug of a kind of staged multicore comprises insulating body 1 and is arranged on the metal ferrule 3 of body interior; The welding lead end 2 of body 1 is provided with ladder platform 4; The welding ends of metal ferrule 3 is fixed on stairstepping end face 10, and the welding ends breach 5 of metal ferrule 3 is towards the direction that deviates from stairstepping end face 10 axis.The stairstepping end face 10 of insulating body 1 makes metal ferrule 3 be in different end faces; Produce (referring to Fig. 2 and Fig. 4) plane I 6, Planar Mechanism 7, plane III 8, plane IV 9; Have only two metal ferrules 3 around the metal ferrule 3 on plane I 6 and the plane III 8, have only three metal ferrules 3 around the metal ferrule 3 on Planar Mechanism 7 and the plane IV 9.The reasonable distribution of the metal ferrule 3 in the insulating body 1 and welding ends breach 5 improve, and when carrying out repair welding, the lead-in wire that welding is accomplished can not block other metal ferrule welding ends, convenient welding.

The concrete course of work is: at first I 6 begins welding to plug portion from the plane, welds Planar Mechanism 7 again, and is same; At first III 8 begins welding to socket part from the plane, welds plane IV 9 again, through this order; Just can reduce solder horn and touch other metal ferrule welding ends; If when carrying out repair welding, the lead-in wire that so just can avoid welding completion blocks the metal ferrule welding ends, raises the efficiency.

Above-described case study on implementation is a kind of preferred version of the present invention, is not the present invention is done any pro forma restriction, is not exceeding variant and the remodeling that also has other under the prerequisite that claim puts down in writing.
