Description

Adjustable anti-loosening HDMI connector device

Technical Field

The utility model relates to an electric connector technical field specifically is an anti-loosening HDMI connector device with adjustable.

Background

The plug of HDMI and the connection between the socket adopt the most common plug-in connection, only rely on the contact friction between plug and the socket sheetmetal to carry on spacingly, under the exogenic action power, for example step on the HDMI connecting wire carelessly, will lead to the contact of sheetmetal to appear becoming flexible to lead to signal transmission unstability or even break off, consequently the HDMI line grafting fixed knot constructs has appeared.

Chinese patent with application number CN201520925287.9 discloses a vehicle navigation multimedia system's HDMI line grafting fixed knot constructs, including the plug that is connected with the HDMI line and locate the socket on the on-vehicle well accuse host computer, the plug includes the plug main part, connect in the public head of HDMI of plug main part front end and locate the fixing base in the plug main part, threaded connection has fastening screw on the fixing base, the socket includes the guide way that is used for holding the plug main part and is used for the female seat of HDMI that pegs graft with the public head of HDMI that the guide way bottom set up, one side of guide way still is equipped with the screw hole with fastening screw complex.

This HDMI line grafting fixed knot constructs through fastening screw and screw hole screw thread interlock, avoids the not hard up between public head of HDMI and the female seat of HDMI, guarantees both grafting complex stability and reliability, but because the screw hole is fixed to be set up, consequently the socket can only use supporting fixed dimension's plug, causes inconvenience for the user.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an anti-loosening HDMI connector device with adjustable, when preventing that plug and socket pine from taking off, the socket can facilitate for the user with not unidimensional plug adaptation.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an anti-loosening HDMI connector device with adjustable, including plug and socket, the plug includes the base and the bayonet joint that sets up on the base, the socket includes mount pad and the confession bayonet joint male socket that sets up on the mount pad, be provided with the anti-disengaging structure that restricts bayonet joint and bayonet joint pine and take off when bayonet joint and bayonet joint are pegged graft between base and the mount pad, anti-disengaging structure includes the movable block that can be close to or keep away from the bayonet joint that moves the setting on the mount pad, the locking structure of restriction movable block and mount pad relative motion that sets up between mount pad and movable block and the fixed knot who sets up restriction bayonet joint and bayonet joint relative motion between movable block and base construct.

Adopt above-mentioned scheme, compare in the fixed setting of screw hole among the prior art, therefore the socket can only use supporting a fixed dimension's plug, cause inconvenience for the user, because the movable block can be close to or keep away from the mount pad in this scheme, consequently, the distance between movable block and the mount pad can be adjusted according to the size of plug, the movable block is adjusted to suitable position back according to the size of plug, make the movable block be quiescent on this target location through locking structure, rethread fixed knot constructs the stillness between realization movable block and the base, restriction bayonet joint and bayonet socket relative motion, thereby avoid the pine between bayonet joint and the bayonet socket to take off.

Further, the locking structure includes the fixed plate that sets up in the one side symmetry that the connector was kept away from to the movable block on the mount pad, the groove that slides that forms between the relative one side of fixed plate, the slide bar that passes the groove that slides that sets up on the movable block and alternate complex splint with the slide bar, be provided with between splint and the slide bar and order about splint and movable block and be close to the removal structure that presss from both sides tight fixed plate and make the movable block static or order about splint and movable block to keep away from and break away from the unblock with the fixed plate.

Adopt above-mentioned scheme, moving structure control splint and movable block are kept away from, make the distance between splint and the movable block be greater than the fixed plate thickness, external force is exerted and is made the slide bar be close to or keep away from the mount pad removal on the slide bar in the groove that slides, thereby it moves to drive splint and movable block to be close to or keep away from the mount pad removal, adjust the distance between movable block and the mount pad, when the movable block removes to with plug size adaptation, moving structure control splint and movable block are close to, both all with the fixed plate butt, thereby it makes the movable block be static on this position to press from both sides tight fixed plate, this cooperation mode makes the movable block stop in optional position, increase the suitability.

Furthermore, the mobile structure comprises a through groove arranged on the clamping plate and used for the sliding rod to pass through, an internal thread arranged on the outer annular wall of the sliding rod, and an external thread arranged on the inner annular wall of the through groove and matched with the internal thread in a threaded manner.

By adopting the scheme, the moving block is rotated to drive the sliding rod to rotate, the clamping plate and the moving block are close to each other under the screw feeding action of the internal screw thread and the external screw thread, and the moving block rotates in the reverse direction, so that the clamping plate and the moving block are far away from each other.

Further, a stable structure for reducing vibration when the clamping plate and the moving block clamp the fixing plate is arranged between the mounting seat and the clamping plate.

Adopt above-mentioned scheme, reduce or avoid splint, slide bar and movable block to produce the slight vibrations in the inslot that slides through stable structure.

Further, stable structure includes the mounting panel that sets up in the one side that bayonet joint was kept away from to splint on the mounting panel, the installation pole and the both ends that set up on the mounting panel cup joint respectively on installation pole and slide bar and with the spring of mounting panel and splint elasticity butt.

Adopt above-mentioned scheme, because the both ends elasticity butt of spring is on mounting panel and splint, the elasticity that resets of spring gives splint a thrust and makes splint firmly butt on the fixed plate to reduce or avoid the vibrations of splint.

Furthermore, the fixed knot constructs including the screw hole of establishing in the movable block is close to one side of bayonet joint is concave on, the fixing base that sets up on the base, run through the shifting chute that sets up, pass shifting chute and screw hole screw-thread fit's screw rod and the stopper that sets up in the one end that the screw hole was kept away from to the screw rod along vertical movement piece moving direction on the fixing base, after the screw rod inserts screw hole screw-thread fit, the fixing base both sides respectively with movable block and stopper butt.

Adopt above-mentioned scheme, when the movable block was adjusted to when the distance between screw hole and the bayonet socket equals the distance between shifting chute and the bayonet socket, after the bayonet socket inserted the bayonet socket, the user rotated the stopper, moved the screw rod and rotated, at screw rod and screw hole screw thread interlock, the fixing base both sides respectively with movable block and stopper butt this moment to restriction bayonet socket and bayonet socket pine takes off, the antiport stopper can make screw rod and screw hole break away from.

Furthermore, a limiting structure for limiting the screw to be separated from the fixed seat is arranged between the screw and the movable groove.

By adopting the scheme, the limiting structure limits the screw to be separated from the fixed seat, and limits the screw on the fixed seat all the time, thereby avoiding the loss of the screw.
