As shown in fig. 1 to 12, the pull rope falling off electric connector based on the steel ball locking structure has the following working principle:
(1) Before the plug 30 and the socket 40 are connected in a plugging manner: the second compression spring 12 is compressed between the plug housing 21 and the second bushing 13; under the action of the second pressure spring 12, the baffle ring A of the second bushing 13 is tightly attached to the connecting ring inner convex block B of the connecting ring 18; the first compression spring 14 is compressed between the plug housing 21 and the first bushing 15; under the action of the first compression spring 14, the first bushing convex ring C of the first bushing 15 is tightly attached to the annular step D of the connecting ring 18; the second bushing outer lug E of the second bushing 13 falls in the gap F of the connecting ring 18, so that the second bushing 13 and the connecting ring 18 cannot rotate; the first liner inner protruding block G of the first liner 15 passes through the liner strip-shaped through hole H of the second liner 13 and then falls into the shell strip-shaped counter bore J of the plug shell 21, so that the plug shell 21, the second liner 13 and the first liner 15 cannot rotate; and thus cannot rotate between the plug housing 21 and the connection ring 18.
(2) During the plugging connection process of the plug 30 and the socket 40: the steel ball 3 pushes the first bushing 15 to compress the first compression spring 14; the socket housing 2 pushes the second bushing 13 to compress the second compression spring 12; the inner wall of the socket housing 2 compresses the shield ring 22; the first bushing outer lug L of the first bushing 15 enters the gap F of the connecting ring 18, so that the first bushing 15 and the connecting ring 18 cannot rotate; the second bushing outer projection E of the second bushing 13 exits the gap F of the connecting ring 18; the first liner inner protruding block G of the first liner 15 passes through the liner strip-shaped through hole H of the second liner 13 and then falls into the shell strip-shaped counter bore J of the plug shell 21, so that the plug shell 21, the second liner 13 and the first liner 15 cannot rotate; thus, the plug housing 21 and the connection ring 18 cannot rotate; the five plug projections N of the plug housing 21 fall into the five receptacle recesses Q of the receptacle housing 2, realizing an erroneous insertion preventing function and a rotation stopping function between the plug 30 and the receptacle 40.
(3) After the plug 30 and the receptacle 40 are plugged into place: the steel balls 3 fall into the annular groove K of the plug housing 21; under the action of the first compression spring 14, the first bushing convex ring C of the first bushing 15 is tightly attached to the annular step D of the connecting ring 18; the inner wall surface of the first bush 15 blocks the steel ball 3 so that the steel ball 3 cannot withdraw from the annular groove K of the plug housing 21; the plug 30 and the socket 40 are fixed in a plugging connection way; the inner wall of the socket housing 2 compresses the shield ring 22; the first bushing outer lug L of the first bushing 15 is withdrawn from the gap F of the connecting ring 18, so that the first bushing 15 and the connecting ring 18 can rotate; the second bushing outer lug E of the second bushing 13 is withdrawn from the gap F of the connecting ring 18, so that the second bushing 13 and the connecting ring 18 can rotate; the first liner inner protruding block G of the first liner 15 passes through the liner strip-shaped through hole H of the second liner 13 and then falls into the shell strip-shaped counter bore J of the plug shell 21, so that the plug shell 21, the second liner 13 and the first liner 15 cannot rotate; thus, the plug housing 21 and the connection ring 18 can be rotated; the contact pin 7 and the jack 19 are plugged in place and are connected at the moment; the plug housing 21 and the socket housing 2 are connected by a shielding ring 22; the plug housing 21 compresses the sealing ring 1 to realize the sealing between the plug 30 and the socket 40; the conical boss T of the packing 4 is pressed tightly with the conical surface S of the hole insulator 20, and each hole site is sealed.
(4) The pulling-out and separating process of the plug 30 and the socket 40: the external mechanism pulls the pull rope 16 to move forwards, the pull rope 16 drives the connecting ring 18 to move forwards, the connecting ring 18 drives the first bushing 15 to move forwards, the first bushing 15 drives the plug housing 21 to move forwards by compressing the first pressure spring 14, and the annular groove K of the plug housing 21 drives the steel balls 3 to move forwards; the steel ball 3 is separated from the rear end of the first bushing 15, and the steel ball 3 is withdrawn from the annular groove K of the plug housing 21; under the action of the second pressure spring 12, the baffle ring A of the second bushing 13 is tightly attached to the connecting ring inner convex block B of the connecting ring 18; the plug 30 and the socket 40 are unlocked; under the action of the first compression spring 14, the first bushing convex ring C of the first bushing 15 is tightly attached to the annular step D of the connecting ring 18; the second bushing outer lug E of the second bushing 13 falls in the gap F of the connecting ring 18, so that the second bushing 13 and the connecting ring 18 cannot rotate; the first liner inner protruding block G of the first liner 15 passes through the liner strip-shaped through hole H of the second liner 13 and then falls into the shell strip-shaped counter bore J of the plug shell 21, so that the plug shell 21, the second liner 13 and the first liner 15 cannot rotate; and thus cannot rotate between the plug housing 21 and the connection ring 18.
In summary, the connector can realize the function of preventing the rotation of the connecting ring 18 in the process of inserting, connecting, pulling out and separating the socket 40 and the plug 30, and simultaneously realize the rotatable function of the connecting ring 18 after the socket 40 is connected with the plug 30, thereby meeting the use requirement.
The above embodiments are only preferred embodiments of the present invention, and are not limiting to the technical solutions of the present invention, and any technical solution that can be implemented on the basis of the above embodiments without inventive effort should be considered as falling within the scope of protection of the patent claims of the present invention.
