Embodiment 1

[0042] This embodiment provides an end-face self-sealing box-type plug-in unit for modularized combined electronic equipment, which adopts a box-type structure with a rectangular flange at the front and a rectangular parallelepiped structure at the rear as a whole. A screw mounting hole is opened on the top, after the main structure of the plug-in unit is loaded into the installation base and fixed to the installation base with screws, it is located between the contact installation surface, that is, between the back of the rectangular flange and the installation surface of the installation base. The elastic sealing material between them is compressed to form a sealing structure, that is, the self-sealing function of the end face can be completed while the butt joint is installed.

[0043] Among them, a wedge-shaped locking device is installed on both sides of the plug-in unit, and an operating hole of the wedge-shaped locking device is correspondingly opened on the rectangular ...

Embodiment 2

[0045] In order to solve the above-mentioned technical problems, the plug-in unit of this embodiment includes a housing, a built-in circuit board, an I / O electrical connector, a handle and other indicating and marking parts, and the overall shape is a cuboid box structure with a rectangular flange on the front. There is a mounting hole on the front rectangular flange surface. When the plug-in unit is fixedly connected to the mounting base by screws, the elastic sealing material between the back of the rectangular flange and the mounting surface of the mounting base is also compressed, that is, in the butt installation At the same time, the end face self-sealing can be completed. A wedge-shaped locking device is installed on both sides of the plug-in unit to provide additional locking force in addition to the aforementioned screw connection, which enhances the overall rigidity of the structure and improves the reliability of fixed locking. In order to operate the wedge lock dev...

Embodiment 3

[0047]This embodiment is shown in Figure 3. The plug-in unit includes a housing, a built-in circuit board, an I / O electrical connector, a wedge locking device, a handle, and other indications and identification parts. The rear part is a box structure with a cuboid structure main body. The handle, indication and identification parts are installed on the front rectangular flange as the human-machine interactive operation interface, the circuit board is packaged inside the rear box, and the I / O electrical connector is located on the rear end surface as the electrical interface of the whole machine, wedge-locked The devices are located on both sides of the rear box. Screw mounting holes are provided on the front rectangular flange surface, and rectangular section grooves are provided on the back of the flange along the inner side of the edge. The grooves are connected end to end to form a continuous and complete rounded rectangular ring structure and embedded with a sealing strip....

Abstract

The invention belongs to the technical field of electronic equipment, and particularly relates to an end-surface self-sealed box-type plugin unit. The integral appearance of the end-surface self-sealed box-type plugin unit is in a way that a cuboid box-type structure with a rectangular flange is arranged at a front part, a screw installation hole is formed in a plane of the front-part rectangularflange, and an elastic sealing material between a contact surface, namely a back surface of the rectangular flange and a matrix installation surface is pressed to form a sealing structure after the plugin unit and the installation matrix are fixedly connected by a screw. A wedge-shaped locking device is arranged at each of two sides of the plugin unit, an additive locking force can be provided after fixed connection of a flange surface screw, the integral rigidity of the structure is improved, and the fixed locking reliability is improved. In the plugin unit, an operation hole is formed in thefront-part rectangular flange and is used for operating the wedge-shaped locking devices, and the operation hole is sealed by a plug after operation is completed. A modular structure design is employed, the whole sealing structure is simplified, the plugin unit is compact in structure and is convenient to assemble and disassemble and can be applied to various types of electronic equipments with relatively high requirements on reliability, maintenance performance and the like.

Description

technical field [0001] The invention belongs to the technical field of electronic equipment, and in particular relates to an end-face self-sealing box-type plug-in unit. Background technique [0002] The existing plug-in units for box-type electronic equipment are commonly used in the following two structures: (1) printed boards with plug-in components, that is, board-type plug-in units, see figure 1 ; (2) Frame or cassette plug-in units with plug-in connections, see figure 2 . The common feature of these two structures is that an independent sealing structure should be designed on the box body. When installing and removing the plug-in unit, the box body must be opened, which causes inconvenience to use and maintenance, and also reduces the reliability of the whole machine. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is: how to provide a plug-in unit that simplifies the seal...
