Description

electrical connector set

The present invention relates to an electrical connector set, in particular to an electrical connector set with a secondary lock.

Most of the traditional connectors are combined by means of quick-connect push-pull, rotary lock or screw thread tightening when docking. However, the docking method of rotating lock or screw thread tightening takes up more space in use and cannot be used in places with limited space; in addition, the docking method of quick-connect push-pull is convenient, but it is pulled or vibrated by external force. It is easy to loose and separate, so the connection effect after docking cannot be guaranteed. Furthermore, in some specific use states, the two connected connectors need to be allowed to rotate relative to each other. However, in this situation, if the vibration is too frequent and strong may cause gradual rotation and loosening.

Taiwan New Patent Certificate No. M605408 discloses "a push-pull self-locking electrical connector", which includes a first connector and a second connector. The first rubber core of the first connector is internally combined with a plurality of first terminals, the cap sleeve is sleeved on the outside of the first rubber core and a stop block is formed on the inner edge surface, and the compression spring is arranged between the first rubber core and the cap sleeve , the buckle structure, the first rubber core and the cap sleeve are combined through the buckle structure, and the buckle structure includes setting an escape groove, a convex block, a sliding groove and a catch block, and the catch block penetrates into the escape groove and After the cap sleeve is rotated, it crosses the protrusion and enters the chute, and the locking block is blocked by the protrusion and cannot move out of the chute. The second connector includes a second rubber core and a plurality of second terminals. The second rubber core is formed with a slot and a backstop; the first connector penetrates the slot through the stopper and is locked by the backstop after being rotated. The second connector is combined with the resistance of the device, thereby completing the quick docking and ensuring the connection effect after docking.

Although the conventional electrical connector uses a quick docking method to ensure the connection effect after the connector is docked, because the connector is docked only by a single lock, it will still be caused by gradual rotation when the vibration is too frequent and strong. lead to loosening.

When the locking member 30 moves from the first position 90 to the second position 91 , the abutting portion 333 abuts on the first platform 1191 of the mounting seat 112 , the protruding The post 331 leaves the second platform 1192 and moves to the opening 1193 and abuts against the protrusion 211 of the docking connector 20 to ensure that the electrical connector 10 and the docking connector 20 do not loosened by vibration.

To sum up, the electrical connector set 100 of the present invention is firstly locked by rotating the cap 11 to lock the electrical connector 10 to the docking connector 20 , and then lock the locking The fastener 30 is pushed from the first position 90 to the second position 91 for a second locking, so as to prevent the cap sleeve 11 from causing the connection between the electrical connector 10 and the docking connector 20 due to vibration loose. Conversely, in order to separate the electrical connector 10 from the mating connector 20 , it is necessary to push the locking member 30 from the second position 91 to return to the first position 90 , and then reversely rotate the locking member 30 . The cap 11 separates the electrical connector 10 from the docking connector 20 . Therefore, the electrical connector set 20 of the present invention has the function of secondary locking, and is not easily loosened under vibration. In specific implementation, the shape of the oblique groove 113 can also be changed in other ways, and the oblique groove 113 can be replaced by a guide groove of any shape that can cooperate with the convex post 331 to play a guiding function. In the specific implementation, the actuating stroke of the locking member 30 may not be limited to the longitudinal reciprocating movement along the insertion direction, and may also be combined with the shape design of the guide groove to repeatedly traverse in the direction orthogonal to the insertion direction. Or relative to the oblique movement in the plug-in direction, as long as the locking member 30 moves to the first position 90, the butt connector 20 can be withdrawn, and when it moves to the second position 91, the butt connector 20 The movement path of the protrusion 211 blocked in the guide groove can be replaced.
