Description

Technical Field

[0001] This application relates to the technical field of electrical connectors, and particularly to an HDMI connector. Background Art

[0002] Currently, when connecting a digital input signal source to other digital electronic devices, such as televisions, receivers, projectors, etc., an HDMI connector is usually used to meet the user's needs for a high-definition digital video system.

[0003] In the related art, an HDMI connector is usually connected to an interface on other devices by plugging. Sometimes, the connection is not tight, the contact is poor, or when the user accidentally collides or pulls, the HDMI connector is easily pulled out of the interface, resulting in a situation that affects the use of the high-definition digital video system. Summary of the Invention

[0004] In order to enable the HDMI connector to be more tightly connected to the corresponding interface, this application provides an HDMI connector.

[0005] This application provides an HDMI connector, adopting the following technical solutions:

[0006] An HDMI connector includes a shielding housing and an insulating body located inside the shielding housing. The shielding housing includes a rear shell and a front shell for plugging into an interface. One end of the rear shell is sleeved outside the front shell. The insulating body includes a tongue plate slidably disposed inside the front shell. The insulating body and the rear shell are detachably connected, and the front shell and the rear shell are detachably connected;

[0007] The front shell includes locking bars on both sides. The locking bars are hollow, and a contact bar is rotatably disposed inside the locking bars. The contact bar includes a contact block at one end away from the rear shell. A turning-out hole for the contact block to turn out is formed on the surface of the locking bar. A locking mechanism is disposed inside the front shell to drive the locking bar to rotate and lock the position after the locking bar rotates;

[0008] An operation plate for driving the locking mechanism is rotatably disposed on the rear shell. The front shell slides inside the inner cavity of the rear shell, and a plurality of plugging bars are slidably connected to the front shell. Plugging grooves for the plugging bars to be plugged into are formed on the inner wall of the rear shell. The operation plate is used to control the sliding of the plugging bars.

[0009] By adopting the above technical solution, during use, the front shell is inserted into the interface, and the operation plate is rotated. Through the locking mechanism, the locking bar rotates, and the abutting block at one end of the abutting bar rotates out of the rotating hole, and is used to tightly abut against the inner wall of the connector or inserted into the groove formed in the inner wall of the interface, thereby restricting the front shell from disengaging from the interface, and the HDMI connector can be more tightly connected to the interface; if it is necessary to briefly disassemble the HDMI connector, the operation plate can be operated to make the insertion bar leave the insertion groove, the front shell remains in the interface, and the rear shell and the insulating body can be quickly removed together. The front shell remaining in the interface can prevent others from using this interface; since the insulating body, the front shell and the rear shell are all detachably connected, it is convenient to install and replace the HDMI connector components, and it is also convenient for rework soldering and inspection.

[0010] Optionally, a rotating seat is fixedly connected inside the locking bar, the abutting bar is hinged to the rotating seat, the locking mechanism includes a pressure bar slidably arranged in the inner cavity of the front shell, and the pressure bar is used to push the end of the abutting bar away from the abutting block to make the abutting bar rotate, and the distance from the rotating seat to the abutting block is less than the distance from the rotating seat to the other end of the abutting bar.

[0011] By adopting the above technical solution, the pressure bar slides to push the end of the abutting bar away from the abutting block to swing around the rotating seat. The locking bars are arranged on both sides of the front shell and are not likely to interfere with the tongue plate. And since the distance from the rotating seat to the abutting block is greater than the distance from the rotating seat to the other end of the abutting bar, by the lever principle, it is more distance-saving when the pressure bar is pressed down.

[0012] Optionally, an extension plate is arranged inside the front shell, and a return spring is arranged between the extension plate and the end of the abutting bar away from the abutting block.

[0013] By adopting the above technical solution, the return spring is arranged to drive the abutting bar to rotate and reset after the pressing plate rises.

[0014] Optionally, the locking mechanism further includes a driving rod rotatably connected inside the front shell, a thrust plate is threadedly connected to the driving rod, the thrust plate is used to abut against the pressure bar and push the pressure bar to move, the operation plate is used to drive the driving rod to rotate, and a limiting member for restricting the rotation of the thrust plate is arranged on the pressure bar.

[0015] By adopting the above technical solution, the operation plate drives the driving rod to rotate. After the thrust plate is restricted from rotating by the limiting member, it can move along the length direction of the driving rod and press down the pressure bar.

[0016] Optionally, a sliding groove for the movement of the pressure bar is formed on the inner wall of the front shell, and the limiting member includes an abutting edge arranged at one end of the pressure bar for abutting against the thrust plate.

[0017] By adopting the above technical solution, both ends of the pressing strip slide in the slideway to limit the moving direction of the pressing strip, the abutting thrust plate and the abutting edge abut against each other to limit the rotation of the thrust plate, and since the thrust plate is threadedly connected to the driving rod, the thrust plate can be driven to move when the driving rod is rotated.

[0018] Optionally, the rear shell includes a raised cavity at the top, the raised cavity is located on the side close to the front shell, the operation plate is rotatably arranged in the raised cavity, the operation plate includes a coaxial operation rod, and a coaxial first gear is fixedly connected to the operation rod, and a coaxial second gear for meshing with the first gear is fixedly connected to the driving rod.

[0019] By adopting the above technical solution, the raised cavity provides a use space for the first gear, the operation rod and the operation plate. When the front shell and the rear shell are plugged and connected, the first gear and the second gear can mesh with each other. When the operation plate is rotated to make the first gear rotate, the second gear can rotate to drive the driving rod to rotate.

[0020] Optionally, a rotation hole for the operation plate to rotate is provided on the top wall of the raised cavity, the operation plate is slidably connected in the rotation hole, a coaxial thrust ring is arranged on the side of the first gear close to the operation plate, a ring groove is provided on the outer wall of the thrust ring, one end of the plugging strip is located in the inner cavity of the front shell, and a moving strip for plugging into the ring groove is connected between the plugging strips.

[0021] By adopting the above technical solution, when the plugging strip is plugged into the plugging groove, the front shell and the rear shell are plugged. The plugging strip can be plugged into the ring groove. Since the operation plate is slidably connected in the rotation hole, when the operation plate slides down, it can drive the first gear and the moving strip to move downward, and the plugging strip can be separated from the plugging groove, so that the front shell and the rear shell are disconnected.

[0022] Optionally, a support strip abutting against the bottom of the operation plate is arranged in the raised cavity, a plurality of support tension springs are arranged between the support strip and the top wall of the raised cavity, and a limiting ring edge for abutting against the top wall of the raised cavity is arranged on the side wall of the operation plate.

[0023] By adopting the above technical solution, when the operation plate slides, it can drive the support strip to move and stretch the support tension spring. After the operation plate is released, the support tension spring releases the elastic force, so that the operation plate can be reset, and the operation plate can be restricted from disengaging from the raised cavity through the limiting ring edge.

[0024] Optionally, a guiding surface is arranged at one end of the plugging strip far from the moving strip, the guiding surface is inclined from the direction close to the rear shell towards the inner cavity of the front shell, and a reset tension spring sleeving the plugging strip is arranged on the moving strip and the inner wall of the front shell.

[0025] By adopting the above technical solution, when the temporarily removed rear shell and the insulating body are reconnected, after the front shell and the rear shell are plugged together, the guiding surface can be pushed and moved through the edge of the plugging groove or the edge of the rear shell, so that the plugging strip moves and stretches the reset tension spring. When the plugging strip moves to the corresponding plugging position, it can be directly plugged into the plugging groove through the reset of the reset spring, and the installation process is convenient without rotating the operation plate.

[0026] In summary, the present application includes at least one of the following beneficial effects:

[0027] 1. After the HDMI connector is plugged into the interface and the operation plate is rotated, the abutting strip is rotated through the locking mechanism, and the abutting block rotates out of the rotating hole, which is used to abut against the inner wall of the joint or plug into the groove formed in the inner wall of the interface, thereby restricting the front shell from disengaging from the interface, and the HDMI connector can be more tightly connected to the interface;

[0028] 2. If it is necessary to temporarily disassemble the HDMI connector, the plugging strip can be made to leave the plugging groove by operating the operation plate, the front shell remains in the interface, and the rear shell and the insulating body can be quickly removed together. The front shell remaining in the interface can restrict others from using this interface;

[0029] 3. Since the insulating body, the front shell and the rear shell are all detachably connected, it is convenient to install and replace the HDMI connector components, and it is also convenient for soldering repair and inspection. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0038] The following will further elaborate on this application in conjunction with the attached Figure 1-7 drawings.

[0039] An HDMI connector disclosed in an embodiment of this application, referring to Figure 1 and Figure 2 , an HDMI connector includes a shielding housing 1 and an insulating body 2. The insulating body 2 includes a tongue plate 21, an upper terminal seat 22, a lower terminal seat 23 and a wire clamp 24 connected by clamping. A total of nineteen connection terminals 25 are passed through the upper terminal seat 22 and the lower terminal seat 23. The connection terminals 25 are divided into two rows and are limited and fixed by the upper terminal seat 22 and the lower terminal seat 23 respectively. One end of the connection terminal 25 is inserted into the groove of the wire clamp 24 for connection with the cable by soldering, and the other end of the connection terminal 25 is located inside the tongue plate 21 for connection with the interface. The shielding housing 1 includes a front shell 3 and a rear shell 4. Clamping blocks 26 are integrally provided on the side walls of the upper terminal seat 22 and the lower terminal seat 23 for clamping and fixing with the rear shell 4. Multiple insulating partitions 241 for separating cables are fixedly connected to one end of the wire clamp 24 away from the tongue plate 21, which can improve the signal shielding effect between signal lines.

[0040] The front shell 3 and the rear shell 4 are slidably connected and detachably connected. The front shell 3 is hollow for covering the tongue plate 21 and for plugging and matching with the interfaces of some devices. One end of the rear shell 4 is sleeved outside the front shell 3 for covering most of the insulating body 2 and for connecting with the cable.

[0041] Referring to Figure 2 and Figure 3The front shell 3 includes locking strips 31 on both sides. The locking strips 31 are hollow, and the tongue plate 21 is located between the two locking strips 31. The front shell 3 includes an extension cavity 32 near one end of the rear shell 4. The extension cavity 32 protrudes outward away from the center of the front shell 3. The rear shell 4 is correspondingly provided with a protrusion cavity 41 for the extension cavity 32 to slide into. By providing the extension cavity 32 and the protrusion cavity 41, the components arranged inside the two are less likely to interfere with the insulating body 2. The front shell 3 and the rear shell 4 are formed by bending or casting metal sheets. The inner wall of the locking strip 31 near the front shell 3 can be welded after the internal structure of the locking strip 31 is installed, making it easy to install. The terminal 25 is made of metal, and the insulating body 2 is made of plastic material formed by injection molding. In order to reduce stress concentration, a plurality of stress grooves 27 are opened on the insulating body 2.

[0042] Reference Figure 3 and Figure 4 The locking bar 31 is fixedly connected to a rotating base 313, and a long abutting bar 311 is hinged on the rotating base 313. A stop block 312 is fixedly connected to one end of the abutting bar 311. A clearance hole 318 is opened on the surface of the locking bar 31, which allows the stop block 312 to pass through after the abutting bar 311 rotates. A locking mechanism is provided in the front housing 3 to drive the abutting bar 311 to rotate and lock the abutting bar 311 in its rotated position. The abutting bar 311 extends from the clearance hole 318 and can be inserted into a groove provided in the inner wall of the interface, or used to abut against the inner wall of the interface, so that the HDMI connector can be connected to the interface more tightly, and it is less likely to be loose and fall off when pulled.

[0043] Reference Figure 4 and Figure 5 The locking mechanism includes a drive rod 321 that is rotatably connected to the extension cavity 32 and faces the inner cavity of the front shell 3. A thrust plate 35 is threadedly connected to the drive rod 321. Slideways 315 parallel to the drive rod 321 are provided on the inner walls of the two locking bars 31 that face each other. Sliding connections are made to the two slideways 315, each of which has two surfaces that abut against the thrust plate 35 and the end of the abutment bar 311 away from the abutment block 312. A vertical abutment edge 317 is fixedly connected to one side of the abutment bar 316 to limit the rotation of the thrust plate 35. When the drive rod 321 rotates, the thrust plate 35 can move along the direction of the drive rod 321 under the restriction of the abutment edge 317, pushing the abutment bar 316 to move, and the abutment bar 311 can then rotate. The distance between the connection position of the abutting bar 311 and the rotating seat 313 and the abutting block 312 is smaller than the distance to the other end of the abutting bar 311. Through the lever principle, the pressing bar 316 can save more distance when pressing down.

[0044] A extension plate 3151 perpendicular to the inner wall of the adjacent front shell 3 is fixedly connected to the bottom wall of the slideway 315. The extension plate 3151 is located directly below the abutting strip 311 away from the abutting block 312. A return spring 314 is fixedly connected between the extension plate 3151 and one end of the abutting block 312. After the thrust plate 35 rises, by the elastic force of the return spring 314, it is convenient for the pressing strip 316 and the abutting strip 311 to return to their original positions.

[0045] Refer to Figure 6 and Figure 7 , a circular rotation hole 411 is opened on the side wall of the convex cavity 41 away from the inner cavity of the rear shell 4. An operation plate 42 adapted to the rotation hole 411 slides in the rotation hole 411. A part of the operation plate 42 passes through the rotation hole 411. A limiting ring edge 421 for abutting against the inner wall of the convex cavity 41 is fixedly connected to the side wall of the part of the operation plate 42 located inside the convex cavity 41. The operation plate 42 is restricted from sliding out of the rotation hole 411 through the limiting ring edge 421. An operation rod 44 coaxial with the operation plate 42 is fixedly connected to the end surface of the operation plate 42 located inside the convex cavity 41. A first gear 43 coaxial with the operation rod 44 is fixedly connected to the operation rod 44. A second gear 322 coaxial with the first gear 43 and adapted to engage with the first gear 43 is fixedly connected to the driving rod 321. When the first gear 43 and the second gear 322 are engaged, the operator indirectly drives the driving rod 321 to rotate by rotating the operation plate 42. After the abutting block 312 abuts against the inner wall of the interface or is inserted into the groove of the inner wall of the interface, by disassembling the front shell 3 and the rear shell 4, the front shell 3 can be separated from other components of the HDMI connector. The front shell 3 is located inside the interface, occupying the interface and restricting the use of other connectors.

[0046] Refer to Figure 5 and Figure 6 , two fixing blocks 45 are fixedly connected to the inner wall of the convex cavity 41 where the rotation hole 411 is located. A plugging groove 451 is opened on the surface of the fixing block 45 away from the inner wall of the convex cavity 41. Two plugging strips 323 adapted to be respectively plugged into different plugging grooves 451 slide on the inner wall of the extension cavity 32. The positions of the front shell 3 and the rear shell 4 are locked by connecting the plugging strips 323 and the plugging strips 323. A through hole 325 for the plugging strip 323 to slide is opened on the inner wall of the extension cavity 32. A moving strip 33 is fixedly connected to one end of the plugging strip 323 located in the extension cavity 32. A thrust ring 46 coaxial with the first gear 43 is fixedly connected to the side of the first gear 43 close to the rotation hole 411. A ring groove 461 is opened on the outer wall of the thrust ring 46. A moving strip 33 for plugging into the ring groove 461 is fixedly connected to one end of the two plugging strips 323 away from the plugging groove 451. A yielding arc-shaped notch abutted against the operation rod 44 is opened on the moving strip 33. When the operation plate 42 slides along the rotation hole 411, the operation rod 44 and the thrust ring 46 move following the operation plate 42, thereby driving the plugging strip 323 to slide out of the plugging groove 451, and the front shell 3 and the rear shell 4 can be disassembled.

[0047] Refer toFigure 5 and Figure 6 A reset spring 34 is fixedly connected between the movable bar 33 and the inner wall of the extension cavity 32, and is sleeved on the outside of the plug-in bar 323. When the movable bar 33 is out of the annular groove 461, the plug-in bar 323 can be reset under the reset force of the reset spring 34. A guide surface 324 is provided at the end of the plug-in bar 323 that passes through the through hole 325. The guide surface 324 is inclined toward the inner cavity of the front shell 3 in the direction close to the rear shell 4. After the front shell 3 and the rear shell 4 are plugged in, the guide surface 324 can be pushed and moved by the edge of the fixed block 45, so that the plug-in bar 323 moves and stretches the reset spring 34. When the plug-in bar 323 moves to the corresponding plug-in position, it can be directly plugged into the plug-in slot 451 through the reset of the reset spring 314. The installation process is convenient and quick.

[0048] Reference Figure 5 and Figure 6 A support bar 412 is provided inside the raised cavity 41 for contacting the limiting ring rim 421. The support bar 412 has a circular hole for the operating rod 44 to pass through. Support springs 413, located on both sides of the operating rod 44, are fixedly connected between the support bar 412 and the inner wall of the raised cavity 41. When the operating plate 42 moves along the rotating hole 411, the support springs 413 stretch. When the support springs 413 stretch to their maximum length, the operating plate 42 does not disengage from the rotating hole 411, thus limiting the movement of the operating plate 42. After the operating plate 42 is released, the support springs 413 return to their original position, allowing the limiting ring rim 421 to contact the inner wall of the raised cavity 41 again.

[0049] The implementation principle of an HDMI connector according to an embodiment of the present application is as follows: when in use, the front shell 3 of the HDMI connector is plugged into the interface of another device, and the operating panel 42 is rotated. The operating panel 42 drives the operating lever 44 and the first gear 43 to rotate. Due to the meshing of the first gear 43 and the second gear 322, the second gear 322 and the driving rod 321 can rotate. Since the thrust plate 35 and the driving rod 321 are threadedly connected and the rotation is restricted by the abutment 317, the thrust plate 35 can push the pressure bar 316 to move downward. The pressure bar 316 moves to drive the abutment bar 311 to rotate and compress the return spring 314, so that the stop block 312 moves out of the clearance hole 318 for plugging into the groove provided in the interface or pressing against the inner wall of the interface, thereby reinforcing the front shell 3 and the interface, making it difficult for the HDMI connector to detach from the interface. Similarly, by rotating the operating panel 42 in the opposite direction, the stop block 312 can be retracted into the locking bar 31 by the action of the return spring 314, and the HDMI connector can be quickly removed.

[0050] When it is necessary to quickly disassemble the HDMI connector, the operation board 42 can also be pressed down, so that the operation board 42 moves along the rotation hole 411. The operation board 42 drives the operation rod 44, the first gear 43 and the thrust ring 46 to move. The movement of the thrust ring 46 can drive the moving bar 33 to move, so that the plugging strip 323 is separated from the plugging slot 451, thereby quickly separating the front shell 3 and the rear shell 4. Similarly, during installation, by plugging the front shell 3 and the rear shell 4, the edge of the fixing block 45 can push the guiding surface 324. Under the action of the reset tension spring 34, the plugging strip 323 can be plugged into the plugging slot 451 for quick installation.

[0051] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
