[0020] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0021] See attached Figure 1-4As shown, the connector swing and momentary break simulation device of embodiment 1 includes: a bracket 1, on which a protective cover 11 is provided; a simulation mechanism for connector swing and momentary break simulation; a mounting frame 3 fixed in the protective cover 11, on which a female end 31 for connector plugging is provided; and a fixing mechanism arranged on the mounting frame 3 and capable of fixing redundant lines of the connector.

[0022] The bracket 1 can play a supporting role, the tail end of the connector can be placed on the simulation mechanism, the head end of the connector can be inserted into the female end 31, and then the excess wire is fixed by a fixing mechanism to simulate the looseness of the connector under natural conditions. The connector is then driven to rotate and shake through the simulation mechanism to simulate the effect of wind blowing in a natural environment, thereby testing the instantaneous disconnection phenomenon of the connector, testing the strength of the connector, and detecting the threshold of the connector.

[0023] The simulation mechanism includes: a rotating part 2 capable of horizontally rotating inside the bracket 1; a wire opening 21 provided on the rotating part 2 for the connector to pass through, and a driving component provided on the bracket 1 for driving the rotating part 2 to work.

[0024] When the head end of the connector is inserted into the female end 31 and the tail end passes through the wire opening 21, the transition section of the connector becomes the test section. When the rotating part 2 rotates, the transition section of the connector can be driven to rotate, simulating the effect of wind blowing, thereby detecting the instantaneous disconnection phenomenon of the connector.

[0025] Furthermore, the rotating part 2 is arranged in a circular shape, a plurality of wire passing openings 21 are provided, and a bearing 22 whose inner ring is aligned with the wire passing openings 21 is provided on the rotating part 2 .

[0026] The circular rotating part 2 can be provided with a wire passing opening 21 near its outer ring surface, and several wire passing openings 21 can be distributed in a ring shape, which is convenient for simultaneous detection of multiple groups of connectors. The provided bearing 22 can make the inner ring contact the connector. When the rotating part 2 rotates, the rotatable inner ring of the bearing 22 reduces the friction with the connector, thereby preventing the connector from being damaged due to friction.

[0027] Furthermore, a counterweight block 23 is sleeved on the tail end of the connector passing through the wire opening 21, and the tail end of the connector is wrapped with a magic cable tie.

[0028] A through hole is provided in the middle of the counterweight block 23, so that the connector can pass through the through hole, and then the wires of the connector after passing through the counterweight block 23 are wrapped with a magic tie to make its volume larger than the through hole, so that the counterweight block 23 can be limited. The counterweight block 23 can be used to increase the weight of the tail end of the connector to simulate the weight of the connector drooping in a natural environment.

[0029] Furthermore, a rotatable cover plate 12 is provided at the top of the protective cover 11, and a control panel 13 connected to the female end 31 through a wire is provided on the side of the protective cover 11.

[0030] The cover 12 is used to close the top of the protective cover 11. Since it is rotatable, the cover 12 can be turned over for easy maintenance. Since the control panel 13 is electrically connected to the female end 31, it can effectively detect the voltage changes generated by the connector when the rotating part 2 shakes. When the control panel 13 speeds up or slows down the rotation speed of the rotating part 2, the threshold of the momentary disconnection phenomenon can be detected.

[0031] Furthermore, the driving assembly includes: a mounting base 24 fixed on the bracket 1 ; a servo motor 25 vertically arranged on the mounting base 24 ; and a reducer 26 drivingly connected to the output shaft of the servo motor 25 , wherein the output shaft of the reducer 26 is fixedly connected to the rotating part 2 .

[0032] The mounting seat 24 is used to fix the servo motor 25. When the servo motor 25 is working, the torque can be adjusted through the reducer 26, and then the rotating part 2 is driven to rotate.

[0033] Furthermore, the fixing mechanism includes: a partition 5 vertically fixed on the mounting frame 3; a limit member 51 penetrating the partition 5 and arranged horizontally; a nut seat 52 penetrating the limit member 51; and a screw 53 rotatably connected to the partition 5 and rotatably connected to the nut seat 52.

[0034] When the lead screw 53 rotates, the limit member 51 can be driven to move through the nut seat 52. The moving limit member 51 can make the wire at the head end of the connector close to the partition 5, so as to clamp and fix it. Therefore, when simulating shaking, it will not directly affect the plug-in point of the head end of the connector, and when the fixing mechanism is not in use, the plug-in strength of the connector can be simulated tested.

[0035] Furthermore, the bottom of the bracket 1 is provided with universal wheels 14 for enabling the bracket 1 to move.

[0036] Furthermore, a fixing frame 4 is provided on the mounting frame 3 , and a sensor 41 facing the connector is provided on the fixing frame 4 , and the sensor 41 is connected to the control panel 13 by a wire, and the sensor 41 can detect whether the connector is plugged in.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
