Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
As shown in fig. 1 and 2, the utility model comprises a test line plug connecting part 1 and an aviation plug connecting part 2 which are integrally arranged, and also comprises an insulating shell arranged outside the test line plug connecting part and the aviation plug connecting part, wherein the end part jack of the test line plug connecting part is composed of a plurality of circular ring bosses 11, and the circular ring bosses 11 are arranged in a stepped manner from inside to outside in sequence from low to high; the aviation plug connecting part 2 is of a frustum structure, the outer diameter of the upper end of the aviation plug connecting part is smaller than that of the lower end of the aviation plug connecting part, and the diameter and the depth of the inner inserting hole are matched with the diameter and the length of a contact pin of the aircraft plug male head.
In order to achieve the purpose that the aviation plug connector is matched with all types of test line plugs of the switch tester, n cylinders are mutually overlapped in the direction of a shaft neck at the plug connecting part of the test line of the switch tester to form a main body part of the plug connecting part of the test line (wherein n =3, each cylinder is provided with a plug wire hole with a corresponding diameter), and the diameters of the n cylinders are respectively R 1 ,R 2 ,…,R n Wherein R is 1 ＜R 2 ＜…＜R n By adopting the method, the plugs of the test lines of the switch testers with different diameters can be matched so as to achieve the purpose of self-adaptively matching the plugs of the test lines of the switch testers with different diameters. Through the boss structure, the problem of inconvenient insertion caused by using different diameters is solved, and when the switch tester is usedWhen the test line plug shaft neck and the test line plug connecting part are not on the same straight line, the plug can automatically insert into the test line plug connecting part due to the existence of the slope toe, and self-adaptive matching is completed.
The inner ring edges of the circular ring bosses 11 are provided with slope feet 10 for axial insertion of the test wire. The toe 10 is not higher than 45 degrees. Offer the toe of slope and can avoid the last section of round platform to stop that causes when pegging graft to the test wire, simultaneously because the adaptation of different diameters, when reconnecting the patchcord of minor diameter, the setting of toe of slope can make things convenient for the patchcord to fast the bottom of sliding into again under the direction of toe of slope, improves the efficiency of pegging graft, and when pegging graft major diameter or the patchcord of medium diameter, ring convex structure 11 makes its diameter that can the adaptation correspond, and quick target in place.
The difference between the outer diameter and the inner diameter of the lower end of the aviation plug connecting part 2 is not larger than the distance between the aircraft plug male pins. During the in-service use, can make its and aircraft plug between the public head contact pin interval unanimous to when convenient putting aside and pegging graft, after grafting to the bottom, the grafting of the ground of its tip and aircraft plug's ground contact cooperation messenger two is more stable, when having avoided in-service use, after having pegged graft aircraft plug public head, the plug wire messenger of pegging graft or changing different switch testers causes great bending to the contact pin.
The shell at the upper end of the test line plug connecting part 1 is provided with a plurality of friction protrusions 3 for increasing friction and facilitating insertion stress. Through setting up a plurality of friction protrudingly can be in this application of taking peg graft or when demolising resistance face increase of finger, make the operation more stable, avoid because the emergence of the phenomenon such as contact pin bending that the smooth hand of plug drops and bring.
In order to increase the contact area between the aviation plug connecting part of the aviation plug connector and the plane of the aviation plug, the diameter R of the aviation plug connecting part of the switch tester is increased a And is increased. According to the formula
When R is b Under the condition of no changeArea S grow is touched, has reduced contact pin horizontal direction 'S power, reduces buckling of aviation plug contact pin, and wherein Ra is the external diameter, and Rb is the jack diameter, and then has realized cross sectional area' S increase through the above-mentioned structure that sets up the frustum, and then has realized the improvement of stability.
Aiming at the problem that the contact area of the aviation plug connecting part of the aviation plug connector is small and further the contact area is small when the aviation plug is plugged in the aviation plug connecting part, so that the contact pin of the aviation plug is stressed in the horizontal direction greatly and further the contact pin is easy to bend, the invention provides a structural mode for increasing the contact area and further reducing the horizontal normal force applied to the contact pin so as to reduce the bending of the aviation plug.
The invention forms a main body of the connecting part of the test wire plug by overlapping n different cylinders in the direction of a shaft neck; a slope toe of 0-45 degrees is arranged at the joint of different cylinders; at the aviation plug connecting part of the switch tester, the diameter R a The contact area S is increased, and the stress of the contact pin in the horizontal direction is reduced. Furthermore, a slope toe of 0-45 degrees is arranged at the joint of different cylinders to form a self-adaptive aviation plug connector; the design form in the range of the slope toe is not beyond the protection scope of the patent right. At the aviation plug connecting part of the switch tester, the diameter R a The contact area S is increased, and the stress borne by the contact pin in the horizontal direction is reduced; all to increase R a The expression of reducing the bending of the contact pin is the protection scope of the present application.
Aiming at the defect that the connecting part of the test wire plug of the aviation plug connector can not be matched with all test wires of the switch tester, the invention provides a self-adaptive structure mode of the connecting part of the aviation plug, so as to be matched with all types of test wire plugs of the switch tester; aiming at the defect that the contact area of the aviation plug connecting part of the aviation plug connector and the plane of the aviation plug is small, so that the contact pin is easy to bend, the invention provides a structural mode for increasing the contact area so as to reduce the bending phenomenon of the aviation plug, and the test efficiency is well improved.
