DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work are within the scope of the present application.

[0023] An embodiment provided by the present application comprises:

[0024] Reference Figure 1 A set top box automatic tester comprises a box body 11, the box body 11 is rotationally connected with a box cover 12 through a rotating shaft, the back of the box cover 12 is connected with a power supply connector 13 for power supply through an interface, wherein the set top box automatic tester further comprises:

[0025] Reference Figure 1 And Figure 2 A disconnecting mechanism 02 is arranged on the side of the box cover 12, and is used for controlling the connection or disconnection between the power supply connector 13 and the interface of the box cover 12 through the rotation of the box body 11. The disconnecting mechanism 02 comprises a square shell 21, the square shell 21 is slidingly contacted with an arc-shaped toothed plate 23 through a sliding groove, one end of the arc-shaped toothed plate 23 is fixedly connected with a strip rod 22, the side surface of the arc-shaped toothed plate 23 is engaged with a pinion 24, the pinion 24 is engaged with a rack 25, one end of the rack 25 is fixedly connected with a back plate 26, and the back plate 26 is detachably sleeved on the power supply connector 13.

[0026] The back plate 26 is composed of two semicircular plate members which can be connected through screws. When the two semicircular plate members are connected through the screws, the two semicircular plate members are sleeved outside the power supply connector 13. When sleeving, the power supply connector 13 can be moved by moving the back plate 26.

[0027] The square shell 21 is fixedly connected to the side wall of the box cover 12, the top surface of the strip rod 22 is at the same horizontal plane as the top surface of the box body 11, one end of the strip rod 22 is connected to the box body 11 through a rotating shaft, and the rotating shaft on the strip rod 22 is at the same axis as the rotating shaft on the box body 11.

[0028] The rotating shaft of the pinion 24 is connected between the square shell 21 and the box cover 12, and the rack 25 is slidingly contacted with the square shell 21 through a sliding groove.

[0029] Reference Figure 3When the box body 11 is rotated to open from the box cover 12, the bar 22 will be rotated together with the box body 11, and the axis of rotation of the box body 11 and the bar 22 is the same. At this time, when the bar 22 is rotated to open, the arc-shaped toothed plate 23 at the bottom will drive the pinion 24 to rotate, and the pinion 24 will drive the rack 25 to move towards the power supply connector 13, thereby pulling the power supply connector 13 from the interface of the box cover 12 through the rack 25 and the back plate 26. It should be noted that the arc-shaped toothed plate 23 and the rack 25 are not in contact, and the pinion 24 plays a role in rotation.

[0030] The bar 22 is connected to the bolt 27 through the threaded hole at the end away from the rotating shaft, and the bolt 27 is connected to the square shell 21 through the threaded hole.

[0031] The bolt 27 is connected between the bar 22 and the square shell 21 through the threaded hole. When the bolt 27 is connected between the bar 22 and the square shell 21, the position of the bar 22 is locked and cannot be rotated. When the adjusting rod 32 contacts the groove of the top plate 31, the bolt 27 can lock the box body 11 from being rotated to open when the position of the bar 22 is locked, lock the back plate 26 to make the power supply connector 13 stably inserted into the interface at the back of the box cover 12, improve the stability of the interface connection between the power supply connector 13 and the box cover 12, and avoid the disconnection problem that may be caused when the power supply connector 13 line is pulled. When the bolt 27 is not inserted into the square shell 21 and the bar 22, the bar 22 can rotate with the box body 11.

[0032] Reference Figure 1 and Figure 2 The control connection mechanism 03 is provided on the top of the box body 11 and the bar 22, and is used to connect the box body 11 and the bar 22. The control connection mechanism 03 includes the top plate 31, and the top plate 31 is connected to the adjusting rod 32 through the groove.

[0033] The top plate 31 is fixedly connected to the top of the box body 11, and one end of the adjusting rod 32 is rotatably connected to the top surface of the bar 22. When the adjusting rod 32 is rotated in the groove of the top plate 31, the box body 11 and the bar 22 are connected. When the box body 11 is rotated to open, the bar 22 will move together. When the adjusting rod 32 is rotated to contact the baffle on the bar 22, the opening and closing of the box body 11 will not move the bar 22.

[0034] The bar 22 is provided with a baffle on the top corresponding to the adjusting rod 32, which is used to block and limit the adjusting rod 32. Through the baffle, the adjusting rod 32 cannot be disengaged from the bar 22, and the adjusting rod 32 is limited between the top plate 31 and the baffle of the bar 22, and only has a rotation range of ninety degrees.

[0035] Reference Figure 4 In which the explosion shows the structure of each part in the disconnecting mechanism 02 and the control connection mechanism 03.

[0036] Working principle:

[0037] In the maintenance work of the set-top box automatic detection instrument, the box body part 11 is rotated to open so as to maintain the electronic devices in the box cover part 12, and when the box body part 11 is rotated to open, the strip rod 22 and the arc-shaped toothed plate 23 are moved, the arc-shaped toothed plate 23 drives the pinion 24 / rack 25 and the back plate 26 to move, thereby physically disconnecting the power supply connector 13 from the power supply interface of the box cover part 12, completing the power-off of the detection instrument, avoiding the risk of live operation, and meeting the electrical safety specifications.

[0038] After the maintenance work is completed, the box body part 11 is rotated to open, thereby driving the back plate 26 to move reversely, so that the power supply connector 13 is reset and inserted into the power supply interface of the box cover part 12, at this time, the detection instrument is powered, and it is not necessary to reset and insert by hand.

[0039] In use, if it is necessary to detect the electronic devices in the box cover part 12 live, before the box body part 11 is opened, the adjusting rod 32 is rotated to make it contact the baffle of the strip rod 22, at this time, the strip rod 22 and the box body part 11 are disconnected, and when the box body part 11 is opened, the power supply connector 13 is not pulled out by the disconnecting mechanism 02, thereby the operator can detect the internal electronic components under the condition that the detection instrument is not powered off, and various use requirements are met.

[0040] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims.
