Description
Technical field
The utility model relates to be used for electrical connector locking mechanism, specifically, is the rocking arm locking positioning mechanism of electric connector.
Background technology
At present, the electric connector of purposes of the same race on the diesel locomotive comprises socket, becomes to plug the plug, the upset that are connected with socket and be connected the protective cover on the socket; Torsion spring is fixed on the socket, and its front end presses protective cover, and the lower surface of protective cover has projection, and when plug insertion socket, projection can compress corresponding recess on the plug.Being tightly connected of plug and socket compresses realization by placing side by side double torsion spring in the electric connector: strength is very big when installing and operating, and be pressed in part on the protective cover because the unlatching of protective cover, very easily with the protective cover surface abrasion, thereby reduce antiseptic property.The strength of this torsion spring also should not be controlled in addition, brings adverse effect therefore for manufacturing, loading and unloading, operation and the safety of connector.
The utility model content
The utility model solves be in the existing electric connector in actual installation and operating process, the plug loading and unloading are difficult, electric connector anti-vibration performance is low, plug contacts unreliable problem with socket seal, easy for installation when providing a kind of plug and socket to plug together, sealing is reliable, electrical connector locking mechanism simple in structure.
This electrical connector locking mechanism, described electric connector comprise socket, become to plug the plug, the upset that are connected with socket is connected the protective cover on the socket; The lower surface of protective cover has projection, and when plug insertion socket, projection can compress corresponding recess on the plug; Sidepiece at protective cover is provided with the protective cover lock shaft, and it also comprises the rocking arm that is rotatably connected on the socket, has first protective cover locking chute in the bottom of rocking arm; When projection compressed the plug recess, the protective cover lock shaft was arranged in first protective cover locking chute, realizes being tightly connected of plug and socket by protective cover.
Its operation principle: when needs are inserted plug, make protective cover upwards overturn; Rocking arm also upwards rotates; Insert plug then, the protective cover that overturns downwards again compresses corresponding recess on the plug up to the projection of protective cover lower surface; Then rotate rocking arm again, make the protective cover lock shaft enter in first protective cover locking chute, the gravity of rocking arm acts on the plug by protective cover, makes plug contact with socket better, seals more reliable.
As improvement, have second protective cover locking chute on the top of rocking arm to above-mentioned retaining mechanism; On rocking arm, have the protective cover displacement groove that passes rocking arm for the protective cover lock shaft; When protective cover was in the position that covers socket, the protective cover lock shaft was arranged in second protective cover locking chute, realizes being tightly connected of protective cover and socket.When do not insert plug in the socket, when protective cover is in the position that covers socket, the protective cover lock shaft is arranged in second protective cover locking chute, realizes being tightly connected of protective cover and socket.Because the protective cover lock shaft is in second protective cover locking chute on rocking arm top according to different needs or in first protective cover locking chute of bottom, so be provided with protective cover displacement groove, the protective cover lock shaft can pass protective cover displacement groove, and be positioned at rocking arm above or below.And the top that is preferably in rocking arm has the protective cover location notch; When protective cover was in level substantially, the protective cover lock shaft was arranged in the protective cover location notch, overturn downwards to prevent protective cover.The effect of protective cover location notch is to support the protective cover that is in level substantially, conveniently to insert plug or pull the plug out of the socket from socket in socket.
As improvement to above-mentioned retaining mechanism, the protective cover lock shaft is for rotating the protective cover locking roller that is arranged on the protective cover, protective cover locking roller can reduce it and lock the frictional force between chute or the protective cover displacement groove with first protective cover locking chute, second protective cover on the rocking arm, go slick, easy to operate.
As improvement, a protective cover lock shaft and a rocking arm are arranged respectively in the both sides of protective cover to above-mentioned retaining mechanism; Be connected with between two rocking arms and be used to promote the handle that two rocking arms rotate with respect to socket.
As the improvement to above-mentioned retaining mechanism, protective cover is connected on the socket by the upset of protective cover axle, the torsion spring that makes the downward upset of protective cover when being set with in normality on the protective cover axle.When torsion spring has certain opening force when keeping protective cover to open, also make the protective cover lock shaft on the protective cover be pressed on the side that first protective cover is locked chute, second protective cover locking chute or protective cover location notch, lock more reliable.
Above-mentioned retaining mechanism is not all changed plug, that is to say, existing plug all can use in above-mentioned retaining mechanism, equally can reach easy for installation yet, connect reliable effect.
More reliable in order to make that plug contacts with socket, strengthen the anti-vibration performance of electric connector, as to above-mentioned retaining mechanism further more, plug is provided with the plug latch mandrel; Have plug locking chute in the bottom of rocking arm; When plug insertion socket, the plug latch mandrel can be arranged in plug locking chute, realizes being tightly connected of plug and socket.The gravity of rocking arm acts on the plug by the plug latch mandrel, makes plug contact with socket better, seals more reliable.Certainly, same, go slick in order to reduce the frictional force of plug latch mandrel and plug locking chute, to make, easy to operate, the plug latch mandrel is for rotating the plug locking roller that is arranged on the plug.
