Description

Technical Field

[0001] This invention belongs to the field of computer hardware, specifically relating to a small docking station device that can be quickly adapted to a control terminal. Background Technology

[0002] Traditional control terminal equipment has fixed functions and performance. The extended aviation plug interface is customized according to user needs. Moreover, the aviation plug interface is usually integrated with the overall equipment design. Once there is a need to upgrade or change the equipment functions, the entire equipment needs to be redesigned and manufactured. Therefore, the level of product generalization, serialization and modularization is low, which cannot adapt to the trend of rapid product iteration and standardization. It also increases the design cost and design cycle, and has certain limitations. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] The technical problem to be solved by the present invention is how to provide a small expansion dock device that can be quickly adapted to the control terminal, so as to solve the problem of low level of universality, serialization and modularity of the extended aviation plug interface.

[0005] (II) Technical Solution

[0006] To solve the above-mentioned technical problems, the present invention proposes a small expansion dock device that can be quickly adapted to a control terminal. The expansion dock device includes: expansion dock housing (1), cover plate (2), aviation plug plate (3), nut plate (4), magnetic snap-fit ​​connector socket (5), conductive rubber pad (6), non-detachable screw (7) and countersunk screw (8).

[0007] The expansion dock housing (1) is a rectangular cavity. The length, width and external dimensions of the cavity are determined according to the dimensions A×B of the installed aviation connector plate (3). The depth of the expansion dock housing is determined according to the height of the connector after welding on the aviation connector plate. Several support columns are provided to improve the rigidity of the aviation connector plate. The expansion dock housing (1) is provided with connector mounting holes, and the opening design is based on the shape of different connectors. There are mounting threaded holes around the perimeter for mating with the control terminal. Threaded holes are evenly distributed along the edge of the housing for mating with the mounting holes of the cover plate (2). The exterior of the expansion dock housing (1) is designed with a weight reduction groove based on the wall thickness.

[0008] The cover plate (2) is a rectangular thin plate with a thickness of 3mm. Its length and width are consistent with the external dimensions of the expansion dock housing (1). There is a mounting hole in the center of the cover plate for outputting the magnetic snap-fit ​​connector on the back of the aviation plug-in board (3). Screw holes are left around the cover plate to cooperate with the expansion dock housing (1) to seal and install the aviation plug-in board (3).

[0009] The aircraft plug board (3) is a circuit board with connectors welded on both the front and back. It has a length of A and a width of B. Several external output connectors are welded on the front and a magnetic snap-pin connector socket (5) is welded on the back. When the connectors on the front of the aircraft plug board (3) are installed with the expansion dock housing (1), they are fastened by the nut plate (4) provided on the back of its flange or by the threads of the flange itself.

[0010] The nut plate (4) is a square metal plate with a round hole in the middle. The diameter of the hole is larger than the diameter D1 of the rear housing of the connector. The four corners of the nut plate are evenly distributed with threaded holes of M3 diameter. The hole spacing is consistent with the mounting hole spacing of the connector flange.

[0011] The magnetic spring connector socket (5) is a rectangular connector. One end contacts the elastic end of the plug on the control terminal, and the other end adopts the printed circuit board through-hole soldering form. After the connector head and socket are inserted, they can withstand an axial separation force of about 40N.

[0012] The conductive rubber pad (6) is a square pad. The material is conductive and compressible. There is a round hole in the middle. The diameter of the hole is larger than the diameter D2 of the front shell of the connector. The conductive rubber pad has round holes evenly distributed at the four corners. The hole spacing is consistent with the mounting hole spacing of the connector flange.

[0013] The non-detachable screw (7) is an M3×14 screw that passes through the M3 threaded through holes around the expansion dock housing (1). When the expansion dock is not connected to the control terminal, it remains in a non-detachable state. When connected, it is used for secondary reinforcement to prevent the magnetic elastic connector plug and socket from separating under vibration conditions.

[0014] The countersunk screw (8) is a countersunk nail used to fix the cover plate (2) and the expansion dock housing (1) and to make the nail head flush with the cover plate.

[0015] (III) Beneficial Effects

[0016] This invention proposes a small expansion dock device that can be quickly adapted to a control terminal. This invention makes the control terminal and the expansion dock device relatively independent, and the expansion dock device is designed with a small and compact structure. The two are quickly connected by a magnetic spring connector. When the expansion connector interface needs to be changed for special needs, only the expansion dock device needs to be replaced to achieve the adaptation of the control terminal without changing the overall design of the control terminal. This improves the universality, serialization and modularity of terminal products. Attached Figure Description

[0028] To make the objectives, contents, and advantages of the present invention clearer, the specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0029] This invention belongs to the field of computer hardware, specifically relating to a small docking station device that can be quickly adapted to a control terminal.

[0030] To address the aforementioned problems with current control terminals, this invention provides a small docking station device that can be quickly adapted to control terminals. It is characterized by its small size, simple structure, strong interchangeability, convenient connection, and certain environmental adaptability.

[0031] A small docking station device that can be quickly adapted to a control terminal includes: a docking station housing, a cover plate, an aviation connector plate, a nut plate, a magnetic snap-fit ​​connector, a conductive rubber pad, a self-locking screw, and countersunk screws. The aviation connector plate has corresponding connectors welded to its front side for different needs as external output interfaces, and is quickly secured to the docking station housing by adding a nut plate to the back of the connector flange. A magnetic snap-fit ​​connector socket is welded to the back of the aviation connector plate. The cover plate seals the aviation connector plate within the docking station and ensures that all connectors can be plugged in externally. A conductive rubber pad is installed between the connector, the cover plate, and the docking station housing to ensure the docking station's airtightness and electromagnetic shielding. The entire small docking station device quickly connects to the magnetic connector plug on the back of the control terminal via the magnetic snap-fit ​​connector socket and is quickly secured by the self-locking screw to enhance its vibration resistance.

[0032] Example 1:

[0033] This invention features a compact structure and simple installation. The control terminal can be adapted simply by replacing the expansion dock. The magnetic spring-loaded connector reliably transmits signals, improving the versatility, standardization, and modularity of terminal products. To make the objectives, content, and advantages of this invention clearer, the specific embodiments are described in further detail below with reference to the accompanying drawings and examples.

[0034] The present invention provides a small expansion dock device that can be quickly adapted to a control terminal, comprising: expansion dock housing (1), cover plate (2), aviation plug plate (3), nut plate (4), magnetic snap-fit ​​connector socket (5), conductive rubber pad (6), non-detachable screw (7) and countersunk screw (8).

[0035] The expansion dock housing (1) is a rectangular cavity. The length and width of the inner cavity are determined according to the size A×B of the installed aviation connector plate (3), and are not less than (A+5)×(B+5). The external dimensions are not greater than (A+20)×(B+18). The depth of the expansion dock housing is determined according to the height of the connector after welding on the aviation connector plate, which is 25.4mm. Several support columns are provided to improve the rigidity of the aviation connector plate. The expansion dock housing (1) is provided with connector mounting holes, and the opening design is based on the shape of different connectors. There are 6-8 mounting threaded holes M3 around the perimeter for mating with the control terminal. The edge of the housing is evenly distributed with threaded holes M3, 6mm deep, for mating with the mounting holes of the cover plate (2). The exterior of the expansion dock housing (1) is designed with a weight reduction groove according to the wall thickness to make the housing compact.

[0036] The cover plate (2) is a rectangular thin plate with a thickness of 3mm. Its length and width are consistent with the external dimensions of the expansion dock housing (1). There is a mounting hole in the center of the cover plate for outputting the magnetic snap-fit ​​connector on the back of the aviation plug plate (3). Screw holes are left around the cover plate to cooperate with the expansion dock housing (1) to seal and install the aviation plug plate (3). There is an annular groove on the overlapping surface of the cover plate (2) and the expansion dock housing (1) for filling with shielding material.

[0037] The aircraft plug board (3) is a circuit board with connectors soldered on both sides. It has a length of A and a width of B. Several external output connectors are soldered on the front side, and magnetic snap-pin connector sockets (5) are soldered on the back side. When the connectors on the front side of the aircraft plug board (3) are installed with the expansion dock housing (1), they are fastened by nut plates (4) on the back of its flange or by the threads of the flange itself to reduce the stress generated at the solder pins.

[0038] The nut plate (4) is a square metal plate with a thickness of 3mm and a side length range of 15mm to 25mm. It has a round hole in the middle with a diameter larger than the diameter D1 of the rear housing of the connector. The nut plate has threaded holes evenly distributed at the four corners with a diameter of M3. The hole spacing is consistent with the mounting hole spacing of the connector flange.

[0039] The magnetic snap-fit ​​connector socket (5) is a rectangular connector. One end contacts the elastic end of the plug (on the control terminal), and the other end adopts the printed circuit board through-hole soldering form. After the connector head and socket are inserted, they can withstand an axial separation force of about 40N.

[0040] The conductive rubber pad (6) is a square pad with a thickness of 0.81mm. Its material is conductive and compressible. The side length ranges from 15mm to 25mm and is consistent with the side length of the corresponding connector flange. The center is a round hole with a diameter greater than the diameter D2 of the connector front shell. The conductive rubber pad has round holes evenly distributed at the four corners with a diameter of Φ3.5. The hole spacing is consistent with the mounting hole spacing of the connector flange.

[0041] The non-detachable screw (7) is an M3×14 screw that passes through the M3 threaded through holes around the expansion dock housing (1). When the expansion dock is not connected to the control terminal, it remains in a non-detachable state. When connected, it is used for secondary reinforcement to prevent the magnetic elastic connector plug and socket from separating under conditions such as vibration.

[0042] The countersunk screw (8) is a countersunk nail used to fix the cover plate (2) and the expansion dock housing (1) and to make the nail head flush with the cover plate.

[0043] During installation, the nut plate (4) is first inserted into the rear end of the connector to be welded on the front of the aviation connector plate (3), and then the connector is welded. When the aviation connector plate (3) is installed onto the expansion dock housing (1), a conductive rubber pad (6) of the appropriate size is installed between the expansion dock housing (1) and the connector flange, and the conductive rubber pad (6) is kept in a certain compressed state to ensure electromagnetic shielding. The specific installation is as follows: Figure 9 As shown.

[0044] When connecting the small expansion dock to the control terminal, first align the magnetic connector plug and socket and quickly engage them, then tighten 6-8 non-removable screws to secure it. This allows for quick adaptation between the control terminal and the expansion dock. When usage requirements change, only the aviation plug board (3) and the expansion dock housing (1) need to be changed to expand the external connections of the control terminal.

[0045] This invention enables the control terminal and the expansion dock to be relatively independent, and the expansion dock is designed to be small and compact. The two can be quickly connected through a magnetic spring connector. When the expansion connector interface needs to be changed for special needs, only the expansion dock needs to be replaced to adapt the control terminal, without changing the overall design of the control terminal. This improves the versatility, serialization and modularity of the terminal products.

[0046] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
