Abstract

The utility model belongs to a connector accessory, relating to a rectangular connector shield tail clamp for an avionics system. The rectangular connector shield tail clamp is used for mounting, shielding and fixing output wire harnesses of a rectangular connector. A hook and a mounting hole are formed at the front end of a shield tail clamp casing; and wire pressing devices are arranged at the rear end of the shield tail clamp casing and are of two U-shaped structures, wherein one U-shaped structure is fixedly arranged on the shield tail clamp casing. The rectangular connector shield tail clamp disclosed by the utility model has the advantages that a connecting mode of the rectangular connector tail clamp and the connector casing and a connecting mode of a cable shield body are designed into a whole so as to bring convenience to realization of the fastening of cable bunches and electromagnetic sealing of the cable bunches. Due to the adoption of the integrated structural design, the requirement on electromagnetic shield can be met and the mounting space of the connector in the length direction is reduced by nearly 40 percent compared with that of a traditional tail clamp.

Description

A kind of avionics system is with rectangular connector shielding tail folder

Technical field

The utility model belongs to connector fitting, relates to a kind of installation that is used for the rectangular connector bundle of outputs and shielding, fixing avionics system with rectangular connector shielding tail folder.

Background technology

At present, the rectangular connector tail folder that in the avionics system product, adopts, its mounting means is split type; Need tail be pressed from both sides housing 6 usefulness screws during installation and be loaded on the rectangular connector compressing tablet 5, bunch of cables line ball folder 7 hangs on the rectangular connector compressing tablet 5 through hook, and the result of this mounting means is; Line ball folder 7 easy and housing 6 disengagings in the use, fastness is poor, simultaneously owing to have structure interval between line ball folder 7 and the housing 6; Cause electromagnetic radiation leakage easily, this effective control to electromagnetic compatibility is disadvantageous, in addition; This structure volume that takes up room is bigger, influences the installation of aeronautical product.

Summary of the invention

The purpose of the utility model is to propose a kind of a kind of avionics system that satisfies electromagnetic compatibility and fastening requirement is installed with rectangular connector shielding tail folder.The technical solution of the utility model is, the front end of shielding tail folder housing is provided with hook and installing hole, and the rear end of shielding tail folder housing is provided with cord grip, and cord grip is two U-shaped structures, and one of them U-shaped structure is fixed on the shielding tail folder housing.Advantage that the utlity model has and beneficial effect; The utility model with rectangular connector tail folder and connector shell be connected and the connected mode of cable shield body is designed to one; Be convenient to the realization of the fastening of bunch of cables and bunch of cables electromagnetic sealing; Owing to adopt incorporate structural design not only to satisfy the needs of electromagnetic shielding, and make connector reduce nearly 40% than existing tail folder at the installing space of length direction.

Embodiment

The utility model is elaborated with Fig. 4 below in conjunction with accompanying drawing 3.The hook 1 and installing hole 2 that carry on the shielding tail folder housing 3 of rectangular connector; Can be directly installed on the rectangular connector housing; U-shaped cord grip 4 on the shielding tail folder housing 3 can directly compress bunch of cables, and forms reliable the electrical connection with screen on the bunch of cables.The front end of connector shielding tail folder housing 3 is provided with the hook 1 and installing hole 2 that is connected with rectangular connector; The U-shaped cord grip 4 that its rear end design is fixed bunch of cables; Cord grip 4 is two U-shaped structures; One of them U-shaped structure is fixed on the shielding tail folder housing 3, and the U-shaped structure helps compressing of bunch of cables and realizes the electromagnetic sealing property of shielded type cable.

The utility model rectangular connector shielding tail folder, during use removes the compressing tablet on the rectangular connector tail end for overall structure, the utility model directly is contained on the housing of rectangular connector.
