Description

Printed board optical cable mounting and fixing support

Technical Field

This practical new belongs to the electromechanical engineering field, relates to a PCB optical cable installation fixed bolster.

Background

Some accessories on the printed board of the module of the onboard electronic device: such as optical fiber, cable, etc., the cable and optical fiber are easy to damage and fail at the module joint due to the severe vibration environment; therefore, in order to avoid the failure damage, the parts of the accessory structures such as the splitter, the optical fiber connector and the like need to be installed and fixed on the electronic equipment or the PCB.

However, the size and layout density of the module printed boards are becoming more compact due to the size and space limitations of the on-board electronics and the increasing complexity of the functions; if the optical fiber or the deconcentrator is directly arranged on the printed board, the layout and wiring space of the module is seriously occupied, particularly in the modules with smaller size and more compact layout; therefore, a structure is needed to be designed for fixing accessories such as optical fibers, the occupied layout space of the printed circuit board is reduced, and the optical fiber connector can be safely and reliably installed and fixed to avoid damage and failure.

Disclosure of Invention

The utility model aims to solve the problem of the installation and fixation of accessories such as optical fiber MT connectors and deconcentrators at present, and the utility model aims to provide a PCB optical cable installation and fixation support, which can save compact layout space on a PCB printed board and improve the maintainability of equipment.

The invention purpose of the utility model is realized by the following technical scheme:

a printed board optical cable mounting and fixing support comprises a wire clamp support 2 and a wire clamp cover 1;

four corners of the wire clamp support 2 are respectively provided with supporting legs 21, and the supporting legs are provided with a first screw hole 22 for fixing with a printed board and a second screw hole 23 for fixing with a wire clamp cover;

the line card cover 1 is equipped with a plurality of crossbeam 11, and every crossbeam below is equipped with a plurality of draw-in groove 12, and the optical cable that the shape and the size of draw-in groove are fixed as required designs, and the line card cover 1 is gone up and is aligned the department with the second screw and still is equipped with the third screw 13 that runs through.

Preferably, the slot 12 is provided with an elastic buffer therein.

The beneficial effects of the utility model reside in that:

the invention can firmly and reliably install and fix irregular accessories: such as optical fiber splices, splitters, etc., to reduce damage to the modules and fiber optic connectors caused by installation, vibration, etc.

The module printed board space is saved, the printed board area under the mounting bracket can be used for arranging and wiring devices without being affected, and compared with the mode that the module printed board area is directly mounted and fixed on the printed board, a large amount of space is saved and the module printed board area can be used for arranging and wiring.

The wire clamp support and the wire clamp structure are fixed through screws respectively, so that the accessories can be conveniently detached and maintained.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

Referring to fig. 1 to 3, the printed board cable mounting and fixing bracket of the present embodiment mainly includes a wire clip support 2 and a wire clip cover 1.

Four corners of the wire clamp support 2 are respectively provided with supporting feet 21, the height of each supporting foot needs to be larger than that of a device on the printed board, and the wire clamp support 2 is ensured not to interfere with the device on the printed board after being assembled. The supporting leg is provided with a first threaded hole 22 and a second threaded hole 23 which are not penetrated.

The wire clamp cover 1 is provided with a plurality of cross beams 11, a plurality of clamping grooves 12 are arranged below each cross beam, and the shapes and the sizes of the clamping grooves are designed according to optical cables fixed according to needs. An elastic buffer is arranged in the clamping groove, so that the optical cable can be fixed safely and reliably, and the optical cable cannot be damaged. A third threaded hole 13 is arranged at the position of the wire clamp cover 1 aligned with the second threaded hole.

The mounting process of the mounting and fixing bracket for the printed board optical cable is as follows:

1) the countersunk head screws 5 are fixed on the PCB printed board 3 and the chassis frame 4 through the first screw holes 22 of the wire clip support 2.

2) Cable accessories such as an optical fiber splitter 7, an MT plug 8 and the like are placed on the cable clamp bracket, and then the corresponding accessory structure part is fixed by the corresponding cable clamp cover 1 and fixed into the second screw hole 23 by the screw 6 through the third screw hole 13. The screw 6 can also be detached in an anti-dropping way, so that the screw is prevented from being lost.

The embodiment can safely and reliably install and fix the optical fiber MT head, the tail wire deconcentrator and other accessories on the premise of less occupying the module layout space, and can improve the maintainability of the equipment.
