Description

Technical Field

[0001] The present invention relates to a plugging and unplugging device, and more particularly to an automatic plugging and unplugging device for an HDMI line. Background Art

[0002] In the FCT test fixture industry, during the testing and inspection of the main test objects 3C products and many PCB motherboards, there are many standard connector tests that require cable docking and plugging, such as network ports, VGA ports, USB ports, audio I / O ports, HDMI ports, etc. The plugging and unplugging methods of the cables of these interfaces have mostly become standardized and automated, but the automatic plugging and unplugging of cables for the HDMI interface has always been a problem in the industry, because the gap between the male and female heads of the HDMI interface is small, and there is no chamfer design on the connector that is conducive to automatic plugging and unplugging. Therefore, the current plugging and unplugging tests for HDMI cables are generally based on manual plugging and unplugging. Manual plugging and unplugging of HDMI cables is slow and inefficient; and is often limited by space, with very little space for plugging and unplugging operations, which also brings difficulties to manual plugging and unplugging operations. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide an automatic plugging and unplugging device for an HDMI cable in view of the defects of the prior art.

[0004] The technical solution adopted by the present invention to solve the technical problem is: constructing an automatic plug-in and unplug-out device for an HDMI cable, putting an HDMI rubber sleeve on the cable end of the HDMI cable, fixing the HDMI cable end on a carrier tray, and fixing the electric cylinder on the plug-in and unplugging device through a connector.

[0007] In the HDMI cable automatic plug-in and unplug-out device described in the present invention, the electric cylinder fixing block is provided with a rear limit block connected by an anti-rotation pin, the anti-rotation pin is fixed on the electric cylinder fixing block and passes through a small hole on the rear limit block; the rear limit block is clamped and fixed on the movable shaft of the electric cylinder through a connector.

[0008] In the automatic plugging and unplugging device for HDMI cable of the present invention, the automatic plugging and unplugging device for HDMI cable is further provided with an HDMI rubber sleeve, which is sleeved on the cable end of the HDMI cable and is clamped and fixed on the third fixing block by the first fixing block and the second fixing block.

[0009] In the HDMI cable automatic plugging and unplugging device described in the present invention, the first fixing block and the third fixing block are accurately positioned by the first positioning pin, the front limit block is accurately fixed on the carrier tray by the second positioning pin, and the slide rail is accurately fixed on the carrier tray by the third positioning pin.

[0010] The implementation of the HDMI cable automatic plugging and unplugging device of the present invention has the following beneficial effects: the present invention ensures the precise position of the components by setting the positioning pins, limits the rotation of the electric cylinder shaft during the plugging and unplugging process by the anti-rotation pin and the rear limit block, and prevents damage to the tested product by the front limit block; the HDMI cable automatic plugging and unplugging device realizes the full automation of HDMI cable plugging and unplugging, has high safety, good stability, and reduces the labor intensity of human labor. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments, in which:

[0012] Figure 1 Schematic diagram of the automatic plugging and unplugging device for HDMI cable of the present invention

[0013] Figure 2 This is a structural exploded view of the HDMI line automatic plugging and unplugging device of the present invention DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0015] like Figure 1 As shown, the HDMI cable automatic plugging and unplugging device includes a carrier tray 01 , a first fixing block 03 and a second fixing block 04 fixed on the carrier tray 01 through a slide rail 02 , and an electric cylinder 06 fixed through an electric cylinder fixing block 05 .

[0016] Furthermore, a front limit block 07 is provided at the front end of the slide rail 02, and a third fixed block 08 is also provided on the slide rail 02. A connecting block 09 is provided at the lower end of the third fixed block 08, and a connecting head 10 is provided on the connecting block 09. The connecting block 09 and the connecting head 10 are floatingly connected.

[0017] Furthermore, the electric cylinder fixing block 05 is provided with a rear limit block 12 connected by an anti-rotation pin 11, the anti-rotation pin 11 is fixed on the electric cylinder fixing block 05 and passes through a small hole on the rear limit block 12; the rear limit block 12 is clamped and fixed on the movable shaft of the electric cylinder 06 through a connecting head 10.

[0018] Furthermore, the HDMI cable automatic plugging and unplugging device is also provided with an HDMI rubber sleeve 13 , which is sleeved on the end of the HDMI cable 20 and is clamped and fixed on the third fixing block 08 through the first fixing block 03 and the second fixing block 04 .

[0019] Furthermore, the first fixing block 03 and the third fixing block 08 are precisely positioned by the first positioning pin 14 , the front limit block 07 is precisely fixed on the carrier pallet 01 by the second positioning pin 15 , and the slide rail 02 is precisely fixed on the carrier pallet 01 by the third positioning pin 16 .

[0020] First, the PCB 100 to be tested with an HDMI interface is placed on the HDMI line automatic plug-in and pull-out device. The electric cylinder pushes the HDMI line 20 clamped by the clamping block to move forward under the guidance of the slide rail 02 through the connecting block 09 until the HDMI line 20 is successfully inserted into the HDMI interface of the PCB to be tested. By setting a constant value of the plug-in and pull-out stroke and plug-in and pull-out force for the electric cylinder 06 in advance, the plug-in and pull-out success is judged only when the plug-in and pull-out stroke and the plug-in and pull-out force simultaneously meet the set value. The HDMI rubber sleeve 13 made by the mold opening, during the process of HDMI being inserted into the HDMI interface of the PCB 100 to be tested, the HDMI line 20 has a certain degree of flexibility and floating in the four directions of up, down, left and right due to the effect of the plug-in and pull-out resistance, thereby reducing a certain degree of plug-in and pull-out resistance. Assuming that the HDMI line 20 is not fully aligned in the process of approaching the HDMI interface of the PCB 100 to be tested, causing the head of the HDMI line to hit the shell of the HDMI interface of the PCB 100 to be tested, at this time, the resistance received by the electric cylinder 06 will exceed the constant plug-in and pull-out force set in advance, and the electric cylinder will stop pushing forward, thereby ensuring that the PCB 100 to be tested will not be damaged.

[0021] Although the present invention is disclosed through the above embodiments, the protection scope of the present invention is not limited thereto. Without departing from the concept of the present invention, any deformation, replacement, etc. made to the above components shall fall within the scope of the claims of the present invention.
