For the on-off test of a common network cable with RJ45 interfaces at two ends, a network cable tester is usually used. In the test, RJ45 crystal connectors at two ends of the network cable are inserted into a main test end and a remote test end of the network cable tester, and the on-off test of eight sub-cables in the network cable can be completed by opening a test switch.

However, for the on-off test of the plug pin type aviation plug-RJ 45 interface network cable, no mature and effective test means exist at present due to the specificity of the interface.

As shown in fig. 1, from inside to outside, there are a jack 1, an insulating mount 2, an insulating layer 3, a housing layer (which may be a metal housing) 4, and a flange 5. Ten of which jack 1 is denoted by A, B, C, D, E, F, G, H, J, K, respectively, whose positions are specified in the GJB 1610A-2011. The inner diameter Φn=1.25 mm of the 20-gauge jack 1, and the diameter Φp=13.11 mm of the insulating mount 2 are specified by GJB 598A-96. The outer diameter Φt of the shell layer 4=19.07 mm.

The four corners of the flange 5 have screw holes, the pitch r=20.6 mm between the screw holes, and the diameter Φd=3.0 mm of the screw holes. The N, W, X, Y, Z letters are indicated in different directions of the flange 5. Wherein the Y direction is a horizontal rightward direction, the N direction is a vertical upward direction, a clockwise rotation β=65° from the N direction is a Z direction, a direction opposite to the Z direction is an X direction, and a counterclockwise rotation γ=60° from the N direction is a W direction. The jack socket is used for connection with the pin aviation plug, so that the angle corresponding to the direction identification letter of the jack socket can be obtained from the stipulation of the rotation angle of the insulation mounting body 2 of the pin aviation plug.

As shown in the bottom view of the receptacle in fig. 2, attached to the receptacle at the bottom of the receptacle is a contact (which may be a soldered contact) 6. The contact 6 is a contact of 20 # as specified in connection with GJB 1610A-2011. Its width m=2.0 mm.

As shown in fig. 3 to 6, on the outer wall of the case layer 4 in the N, W, X, Y, Z direction, red rectangular marks are respectively provided, the height h=6 mm, and the width a=3 mm. And a corresponding N, W, X, Y, Z letter below the red mark indicates the corresponding direction. In fig. 3, the receptacle side height b=10.9 mm and the other side height f=8.5 mm of the receptacle. And the height i=3.3 mm of the contact body 6.

In the dimensions of the above-mentioned socket structure, the values of the inner diameter Φn of the jack 1, the diameter Φp of the insulating mounting body 2, the diameter Φt of the outer wall of the housing layer 4, the width m of the soldered contact 6, the angles β and γ are all from the standards GJB598A-96 and GJB1610A-2011, while the tolerance ranges of the above-mentioned structural dimensions are also given in these two standards, and for the sake of brevity, the corresponding tolerances are not given in table 1.

In addition, the detailed structure and dimensions of the jack 1 and the solder contact 6 are specified in GJBs 598A-96, and will not be described in detail herein.

Since the 12-10-20 pin aviation plug is designed and manufactured according to the GJB598A-96 and GJB1610A-2011 standards, most of the structures and dimensions of the sockets shown in FIGS. 1-6 are consistent with the two standards, and the innovation points of the utility model are mainly the following two points.

First, the outer side of the receptacle housing layer 4 is free of staples and the inner side is free of keyways. According to the GJB598A-96 standard, in order to realize firm clamping between the aviation plug and the socket, the outer side of the shell layer 4 of the socket is provided with a clamping nail, and the inner side is provided with a key groove. And N, W, X, Y, Z plugs of five different subclasses, the relative positions of the insulating mounting body 2 and the key slot of which are different. To achieve a socket that can test five plugs, the present application removes the staples on the outside of the socket housing layer 4 and the key ways on the inside and enlarges the inside diameter Φs of the housing layer 4. The outer diameter Φt=19.07 mm of the No. 12 shell layer 4, the inside keyway root corresponding diameter is 17.63mm, as specified by GJB 598A-96. Since the key way is removed, the inner diameter of the shell layer 4 is between the outer diameter of the shell layer 4 and the corresponding diameter of the inner key way root, i.e. between 17.63mm and 19.07mm, which in this embodiment takes the value Φs=18.00±0.3mm. The clamp pin and the key groove on the inner side of the shell layer 4 of the existing jack type socket are removed, so that the fixity of the jack type socket and the pin type aviation plug in fit is eliminated, and a technical foundation is laid for realizing the plug type aviation plug of one jack type socket to be connected into and test multiple subclasses.

Second, as shown in fig. 1, letters "N, W, X, Y, Z" are marked in the corresponding direction of the flange 5. The Y direction is the horizontal right direction along the C, J, K, G contact hole center, the N direction is perpendicular to the Y direction, the Z direction is 65 ° clockwise rotated relative to the N direction, the W direction is 60 ° counterclockwise rotated relative to the N direction, and the opposite direction of the Z direction is the X direction. As shown in fig. 3 to 6, the outer wall of the housing layer 4 in the direction of the respective letter is marked with red and the corresponding letter is noted. When the aviation plug is used for being connected with the jack type socket, the main key on the plug is aligned with the corresponding letter and the red mark on the socket according to the type of the plug, and then the plug can be inserted for connection. The application uses the cross section central point of the insulating installation body 2 as the center, and sets corresponding marks on the azimuth of a plurality of preset angles, so that when the pin aviation plug is used to be connected with the jack type socket, the main key on the plug is aligned with the corresponding marks on the socket according to the type of the plug, and the connection can be quickly and accurately realized, thereby improving the convenience of the insertion connection of the pin aviation plug and the jack type socket.

In another embodiment, the test device shown in fig. 7 is used to test the on-off of the pin aviation plug-RJ 45 interface network cable by using the jack type socket shown in fig. 1-6. As shown in fig. 7, the A, B, C, D, E, F, G, H, J nine terminals of the socket are respectively connected to the same-name ports of the test circuit, and the K-terminal is used as a spare, and is not connected. While the eight wire terminals and one shield terminal of an RJ45 jack with metallic shields are connected to the 1 to 9 ports of the test circuit, respectively. The test circuit can adopt the existing mature network cable test circuit to realize automatic test on the on-off of nine network cables. The test device for conducting the on-off test of the plug type aviation plug-RJ 45 interface network cable by using the jack type socket is constructed, so that the plug type aviation plug-RJ 45 interface network cable comprising the plug type aviation plugs of various types is accessed and tested on the same test device through one jack type socket.

In the specific construction of the test device, a printed circuit board may be employed. According to the connection relationship shown in fig. 7, the jack type jack, the RJ45 jack and the test circuit can be laid out on a printed circuit board through which the circuit connection between the above units is achieved.

In order to increase the firmness of the test device, the jack socket shown in fig. 1 can be fixed on the printed circuit board by screws at four corners of the flange 5.

During specific test, one end RJ45 connector of the pin type aviation plug-RJ 45 interface network cable is plugged into the corresponding RJ45 socket, and the other end pin type aviation plug is plugged into the corresponding jack type socket. Then, the on-off test of nine lines in the plug pin type aviation plug-RJ 45 interface network cable can be realized by opening a switch of the test circuit.
