DETAILED DESCRIPTION

[0027] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Reference Figures 1 to 12As shown, a high- and low-frequency mixed adapter connector for aircraft or suspension systems includes an adapter shell 1, a connecting nut assembly 6, a sealing ring 2, a locking screw 5, a shielding ring 7, a retaining ring 3 and an adapter shell assembly 4. The adapter shell 1 is equipped with an adapter shell assembly 4. The adapter shell assembly 4 is provided with an anti-radial rotation groove 4-1-1-2 which cooperates with the convex key 1-4 in the adapter shell 1 to prevent radial rotation. The retaining ring 3 is fixed in the retaining ring groove 1-2 of the adapter shell to play the role of axially positioning the adapter shell assembly 4; the connecting nut assembly 6 is fixed in the groove of the adapter shell 1 by the locking screw 5, and the shielding ring 7 is installed on the circumference of the docking end of the adapter shell to hold the shell tightly, and its pawl 7-1 is stuck in the groove 1-5 of the shielding ring 5 of the adapter shell, and the sealing ring 2 is installed in the sealing ring groove 1-1 of the adapter shell. The fixing hole 1-3 on the adapter shell 1 can achieve rigid binding with the bracket, so that the connector can work stably under strong vibration and impact environments.

[0030] The adapter shell assembly 4 includes a shell 4-1 and a wired adapter pin insulator assembly 4-2. The shell 4-1 is divided into two parts from the middle part 4-1-3, namely the upper shell 4-1-1 and the lower shell 4-1-2, and are used in combination. The insulator 4-2-1-2 of the wired adapter pin insulator assembly 4-2 is provided with an axial positioning platform 4-2-1-2-1 and a radial anti-rotation platform 4-2-1-2-2. The shell is provided with an axial 4-1-4 / radial 4-1-5 positioning groove to ensure the axial and radial positioning of the wired adapter pin insulator assembly 4-2 and the shell 4-1. The upper and lower shells 4-1-1 and 4-1-2 fix the wired adapter pin insulator assembly 4-2 therein and perform potting treatment through the potting hole 4-3 on the shell to achieve the fixation of the internal wires and the insulator assembly and environmental resistance.

[0031] 5 The wired adapter pin insulator assembly 4-2 includes a pin insulator assembly 4-2-1,

[0032] The 8# / 12# / 16# / 20# wired adapter pin assembly (4-2-2 / 4-2-3 / 4-2-4 / 4-2-5), 8# dummy contact 4-2-7, and retaining tube 4-2-6 are inserted into the corresponding holes of the pin insulator assembly 4-2-1 using a feeding tool and axially positioned using claws 4-2-1-5. When assembling the wired adapter pin assembly 0 (4-2-2 / 4-2-3 / 4-2-4 / 4-2-5) with the pin insulator assembly 4-2, the high- and low-frequency wires must be properly cross-routed to ensure both axial dimensions and signal continuity in the corresponding holes.

[0033] The pin insulator assembly 4-2-1 is formed by assembling and bonding a front pin insulator 4-2-1-1, a rear pin insulator 4-2-1-2, an interface sealing body 4-2-1-3, a sealing body 4-2-1-4, and a clamping claw 4-2-1-5.

[0034] The 8# wire-carrying adapter pin assembly 4-2-2 is assembled and crimped by the 8# twisted shielded pair pin contact 4-2-2-3, the fixing tube 5 4-2-2-2, and the twisted shielded pair wire 4-2-2-1. The 12# wire-carrying adapter pin assembly 4-2-3 is assembled and crimped by the 12# coaxial pin 4-2-3-2 and the 12# coaxial wire 4-2-3-1. The 16# wire-carrying adapter pin assembly 4-2-4 is assembled and crimped by the 16# pin 4-2-4-2 and the 16# wire 4-2-4-1. The 20# wire-carrying adapter pin assembly 4-2-5 is assembled and crimped by the 20# pin 4-2-5-2 and the 20# wire 4-2-5-2-1, and the wire length is reserved according to the relevant size requirements.

[0035] The connecting nut assembly 6 includes a connecting nut 6-3, a spring claw 6-1, and a rivet 6-2. The spring claw 6-1 is riveted to the connecting nut 6-3 through the rivet 6-2.

[0036] This adapter connector is used for connecting the aircraft and the pylon interface. When the aircraft end is equipped with a pin plug, it can be normally connected to the pylon end socket to achieve normal signal connectivity. When the aircraft end is equipped with a hole plug, it cannot be connected to the pylon end socket and needs to be connected with the adapter connector before connecting with the aircraft end plug. The development of this adapter connector enables the same pylon interface to adapt to different aircraft end interfaces, realizing the universalization of the pylon.

[0037] The above description is merely a specific embodiment of the present invention and should not be construed as limiting the scope of the invention. Therefore, substitutions of equivalent components, or equivalent changes and modifications made within the scope of patent protection, should still fall within the scope of this patent. Furthermore, the technical features of the present invention may be freely combined with one another, with other technical solutions, and with other technical solutions.
