Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to a connector assembly with convenient operation. Background Art

[0002] Connector assemblies used in various applications for, e.g., establishing electrical connections often use a large number of connection terminals, thus requiring large insertion forces and, in particular, release (i.e., extraction) forces to ensure the connection between the connector parts of the assembly. Considerable frictional and clamping forces of the terminals must be overcome to properly connect and disconnect the connector parts. In addition, to ensure that the connection functions properly under various conditions, the connector parts must be fixed to prevent unwanted extraction.

[0003] For this purpose, the prior art CN110462943A provides a connector assembly. By turning the operating handle from the first position to the second position, the force required to overcome the insertion or insertion force in the mating state by the operating handle can be easily increased by the lever principle, and then the connection or separation of the two connectors can be realized. Even an operator can release the tightly adapted connection state with a very small force.

[0004] However, the operating handle is in a free state after being latched, thus affecting the stability of the operating handle and its connector. Summary of the Utility Model

The first positioning post 13 and the limiting block 15 are both located at the rear end of the first hinge portion 14 based on the insertion direction X.

[0020] The second connector 2 is provided with a plurality of second terminals 21 extending along the insertion direction X. The plurality of second terminals 21 are arranged along the width direction Y, and the rows of the plurality of second terminals 21 are arranged along the height direction. At both ends of the second connector 2 in the width direction Y, second width side walls 22 are respectively provided. On each side of the second width side wall 22, a configuration block 23 is provided. The configuration block 23 extends along the height direction and is arranged as a straight blocking block. At the rear end of the configuration block 23 in the insertion direction X, a second positioning post 24 is provided. The second width side wall 22 is provided with a connecting plate 25 extending along the insertion direction X. The connecting plate 25 extends along the insertion direction and is connected to the configuration block 23. The connecting plate 25 is used for welding and fixing on the substrate. The connecting plate 25 is provided with an avoidance groove 26, and the avoidance groove 26 is located at the front end of the configuration block 23 based on the insertion direction X.

[0021] The operating handle 3 includes a cover plate 31 and two side plates 32. The two side plates 32 are located on both sides of the cover plate 31 based on the width direction Y. On each side of the side plate 32, a second hinge portion 322, an arc-shaped groove 321, a mating groove 326, and a card slot 327 are provided. The second hinge portion 322 is arranged as a hinge hole. The arc-shaped groove 321 is located on the outer periphery of the second hinge portion 322, and the center of the arc-shaped groove 321 is located at the second hinge portion 322. On the outer periphery of the second hinge portion 322 of the side plate 32, a mating edge is provided. The mating edge includes an arc portion 323, a straight portion 324, and an end portion 325. The straight portion 324 is connected between the arc portion 323 and the end portion 325, and the center of the arc portion 323 is located at the second hinge portion 322. At the end portion 325 of the cover plate 31 close to the first connector 1, a deflecting plate 33 is provided. The deflecting plate 33 is arranged at an obtuse angle with the cover plate 31. The side plate 32 is connected to the deflecting plate 33 and encloses an avoidance space 331. At one end of the cover plate 31 close to the second connector 2, a window 311 is provided. The window 311 is located at the rear end of the second terminal 21 based on the insertion direction X.

[0022] Refer to Figure 3 , in the connected state, the front end of the first connector 1 in the insertion direction X is connected to the front end of the second connector 2 in the insertion direction X. As the operating handle 3 is pulled and rotated, under the hinge connection between the first hinge portion 14 and the second hinge portion 322, the first positioning post 13 is separated from the arc-shaped groove 321. As the mating groove 326 mates with the configuration block 23, the first connector 1 and the second connector 2 are further pushed to be connected. Then, the limiting block 15 abuts against the mating edge, the straight portion 324 abuts against the limiting block 15, and the end portion 325 is located in the avoidance groove 26. And on the outer periphery of the card slot 327 of the side plate 32, a guiding inclined surface 328 is provided. The second positioning post 24 is in sliding fit with the guiding inclined surface 328, and the second positioning post 24 is engaged with the card slot 327 to relatively fix the locked position of the operating handle 3.

[0023] Refer to Figure 4, in the separated state, the first connector 1 is separated from the second connector 2. As the rotation handle 3 is pulled, with the first hinge portion 14 hinged to the second hinge portion 322, the mating edge abuts against the configuration block 23, that is, the end portion 325 abuts against the configuration block 23 and drives the second connector 2 to move outwards and separate. As the handle 3 rotates, the arc portion 323 has a clearance fit with the configuration block 23, the mating groove 326 can be separated from the configuration block 23, and the second positioning post 24 is separated from the card slot 327. The first positioning post 13 is used in cooperation with the arc-shaped groove 321 to relatively fix the open position of the handle 3. And due to the provision of the avoidance space 331, the opening angle of the handle 3 is larger, which is convenient for the reconnection of the connectors.

[0024] As can be seen from the above, by rotating the handle and using the cooperation between the mating groove and the configuration block, it is convenient for the connection and separation of the connectors. And the limiting block can be used to limit the rotation position of the handle, and cooperate with the engagement of the second positioning post and the card slot, so as to relatively fix the locking position of the handle. In the separated state, the first positioning post and the arc-shaped groove can be used in cooperation to relatively fix the open position of the handle. And with the provision of the avoidance space, the opening angle of the handle is larger, which is convenient for the reconnection of the connectors. And the provision of the window not only allows the cable connected to the terminal to be led out for use, but also reduces the stress on the handle. Increasing the arrangement of the window can increase the elastic deformation of the handle, which is convenient for the engagement and separation of the second positioning post and the card slot, and the cooperation and separation of the first positioning post and the arc-shaped groove.
