Abstract

The utility model provides a dual-safe secondary-locking rectangle electric connector, which is chiefly composed of a plug (1) and a socket (2). The dual-safe secondary-locking rectangle electric connector is characterized in that: the two sides of the plug (1) are respectively provided with a spanner (3) and a reed (4); the lower part of the plug (1) is penetrated and sheathed on the positioning pin (6) of the housing (5); the upper part of the plug (1) is mutually and movably connected through a rivet (7); a torsion spring (8) which is used for clamping the spanner is arranged between the reed and the housing; one end of the torsion spring (8) is also penetrated and sheathed on the positioning pin (6); the other end of the torsion spring (8) and the spanner are penetrated and sheathed on the shaft pin (9) of the housing; the two sides of the socket (2) are provided with an ear table (10) which is clamped with the spanner (3), and the ear table (10) can lock the plug and the socket. The locking mechanism of the utility model has simple and reasonable structure, reliable locking, convenient and rapid usage, good anti-shock effect, and stable information transmission; after inserting the dual-safe secondary-locking rectangle electric connector, the secondary locking can be clamped, and the firmness is strong.

Description

Dual fail-safe secondary locking type rectangular electric connector

Affiliated technical field

The utility model relates to a kind of electric connector, specifically a kind of rectangular electric connector retaining mechanism that makes plug and socket realize secondary locking.

Background technology

At present, rectangular electric connector generally is directly plug and socket to be plugged together, and this connection is unreliable, easily comes off.Existing a kind of locking and disengaging are wasted time and energy by screw and the nut mechanism with plug and socket locking, and efficient is low, easily get rusty.In addition, the plug and socket limit of existing rectangular electric connector is right-angle side, and is stiff when plugging together, the cunning that has some setbacks, and anti-easily inserting caused the short circuit burning apparatus.

Summary of the invention

In order to overcome the shortcoming of prior art, the purpose of this utility model provides a kind of simple in structure, easy to use, safe and reliable dual fail-safe secondary locking type rectangular electric connector.

The technical solution of the utility model is: mainly comprise plug and socket, spanner that the plug both sides are respectively equipped with and reed bottom are set on the alignment pin that is fixed in housing, its top is flexibly connected mutually by rivet, being provided with torsion spring one end that makes the spanner clamping between reed and housing also is set on the alignment pin, the other end and spanner are set on the pivot pin that is fixed in housing, the socket both sides are provided with the ear platform with the spanner clamping, realize once locking with plug, be pushed into reed in the spanner fully, external force can't act on reed, spanner can not be opened with the ear platform engage all the time, reach secondary locking purpose.

The beneficial effect that the utility model reaches is: retaining mechanism advantages of simple, reliable lock, convenient and swift, anti-vibration, message transmission are stablized, but the plug and socket socket is the round edge counnter attack on one side to be inserted, and plugs together smooth and easyly, realizes that one inserts the firm performance that can engage secondary locking.

Description of drawings

Fig. 1 is the structural representation that electrical connector plug and socket plug together locking.

Fig. 2 is structural representation when retaining mechanism is locked on the plug.

Fig. 3 is the structural representation during retaining mechanism release on the plug.

In shown in Fig. 1,2,3, plug 1, socket 2, spanner 3, reed 4, housing 5, alignment pin 6, rivet 7, torsion spring 8, pivot pin 9, ear platform 10.

Embodiment

The utility model will be further described below in conjunction with the drawings and specific embodiments.

As Fig. 1,2, a kind of dual fail-safe secondary locking type rectangular electric connector in shown in 3, mainly comprise plug 1 and socket 2, the spanner 3 of plug 1 both sides and reed 4 bottoms are set on the alignment pin 6 that is fixed in plug casing 5, reed 4 tops are provided with chute and are set on the rivet 7 that is fixed in spanner 3, make reed 4 can depend on spanner 3 inboard spacing sliding up and down, 5 of reed 4 and housings are provided with torsion spring 8, the lower end of torsion spring 8 and spanner 3, reed 4 the same being set on successively on the alignment pin 6, the other end and spanner 3 are set on the pivot pin 9 that is fixed in housing 5 in the lump, and socket 2 both sides are provided with the taper ear platform 10 with spanner 3 clampings.

When plug 1 plugs together with socket 2, reed 4 in the plug 1 both sides spanner 3 is pulled out a bit (distance of reed top chute) downwards, make plug 1 be in released state, the setting circle arm of angle with plug, socket coincide then, in plug insertion socket, along with one " click is rattled away " sound, the spanner 3 of plug both sides hangs on the ear platform 10 of socket both sides, make plug and socket realize once locking, again reed 4 upwards is pushed in the spanner 3 fully, external force can't act on reed, and torsion spring is in non operating state, reaches secondary locking purpose.

When plug separates with socket, reed 4 is pulled out a bit from spanner 3, inwardly push the both sides spanner with thumb and forefinger, reed 4 compresses torsion spring 8, making spanner 3 is that one at fulcrum inwardly folds on alignment pin 6 with pivot pin 9, one open with socket on ear platform 10 break away from, can take advantage of a situation unplugs plug and socket, realizes separation.

Claims

1, a kind of dual fail-safe secondary locking type rectangular electric connector, mainly comprise plug (1) and socket (2), it is characterized in that: spanner (3) that plug (1) both sides are respectively equipped with and reed (4) bottom are set on the alignment pin (6) that is fixed in housing (5), its top is flexibly connected mutually by rivet (7), being provided with torsion spring (8) one ends that make the spanner clamping between reed and housing also is set on the alignment pin (6), the other end and spanner are set on the pivot pin (9) that is fixed in housing, and socket (2) both sides are provided with the ear platform (10) that makes plug and socket locking with spanner (3) clamping.

2, a kind of dual fail-safe secondary locking type rectangular electric connector according to claim 1 is characterized in that: the socket of described plug and socket is round edge on one side, and another side is a right-angle side.
