[0058] Embodiment 1:

[0059] Embodiment 1 of the present application provides a connector auxiliary plugging device, as shown in Figure 1 The connector auxiliary plugging device comprises a transmission assembly 1 and two plier bodies 2, wherein:

[0060] AsFigures 1-3 As shown, the two said pliers 2 are rotatably connected; one end of the pliers 2 is a transmission end 21, and the other end is a clamping end 22. The sliding nut 211 can slide up and down relative to the transmission end 21.

[0061] In one embodiment, the two said pliers 2 are rotatably connected to the fixed shaft 3, and the two pliers 2 can rotate at a certain angle with the fixed shaft 3 as the center.

[0062] The part of the two pliers 2 on the upper side of the fixed shaft 3 is the transmission end 21, and the part of the two pliers 2 on the lower side of the fixed shaft 3 is the clamping end 22. The transmission end 21 is used to receive external driving force, so as to rotate at a certain angle with the fixed shaft 3 as the center. The clamping end 22 is used to rotate at a certain angle with the fixed shaft 3 as the center under the condition that the transmission end 21 is driven by external driving force, so as to make the two opposite clamping ends 22 close to each other, so as to clamp the connector through the two opposite clamping ends 22, thereby removing the connector.

[0063] In one embodiment, the sliding nut 211 is arranged on the transmission end 21 and can move in the up-down direction along the transmission end 21. It should be noted that at least one sliding nut 211 is arranged on the transmission end 21 of each plier 2.

[0064] As shown in the figure, Figures 1-3 The transmission assembly 1 includes a transmission screw 11, and the transmission screw 11 has a forward thread 111 and a reverse thread 112 arranged on both ends respectively. The screw threads of the forward thread 111 and the reverse thread 112 are opposite in rotation direction. Two sliding nuts 211 are respectively sleeved on both ends of the transmission screw 11, one of which is threadedly connected with the forward thread 111, and the other is threadedly connected with the reverse thread 112.

[0065] In this embodiment, the two sliding nuts 211 on the two jaw bodies 2 are identical in structure; the threads of the forward thread 111 and the reverse thread 112 are opposite in rotation direction. When the transmission screw rod 11 rotates, the forward thread 111 drives one of the sliding nuts 211 to move in a first direction, and the reverse thread 112 drives the other sliding nut 211 to move in a second direction, the first direction and the second direction being opposite, thereby driving the two sliding nuts 211 to move in opposite directions on the transmission screw rod 11. On the other hand, the sliding nut 211 can slide up and down relative to the transmission end 21 of the jaw body 2, thereby changing the relative distance between the sliding nut 211 and the fixed shaft 3, and also ensuring that the sliding nut 211 moves on the transmission screw rod 11 while driving the jaw body 2 to rotate by a certain angle around the fixed shaft 3, so as to change the relative distance between the two opposite clamping ends 22. In this embodiment, the lengths of the forward thread 111 and the reverse thread 112 on the transmission screw rod 11 can be consistent.

[0066] As shown in Figure 3 , the transmission screw rod 11 is used to drive the two sliding nuts 211 to move towards or away from each other on the transmission screw rod 11 when the transmission screw rod 11 rotates, thereby driving the two clamping ends 22 on the two jaw bodies 2 to open and close.

[0067] In this embodiment, as shown in Figure 3 , the transmission screw rod 11 can be manually driven to rotate, and when the two sliding nuts 211 on the two jaw bodies 2 move towards each other along the transmission screw rod 11, the two clamping ends 22 on the two jaw bodies 2 rotate in opposite directions with the fixed shaft 3 as the center, and the distance between the two clamping ends 22 increases; when the two sliding nuts 211 on the two jaw bodies 2 move away from each other along the transmission screw rod 11, the two clamping ends 22 on the two jaw bodies 2 rotate towards each other with the fixed shaft 3 as the center, and the distance between the two clamping ends 22 decreases. Figure 3 The arrow on the side of the transmission screw rod 11 in the figure is the rotation direction of the transmission screw rod 11, and the arrows on the two clamping ends 22 are the movement directions of the clamping ends 22 on the transmission screw rod 11.

[0068] The application scenario of the connector auxiliary plugging device provided in the embodiment is that the connector is clamped by the connector auxiliary plugging device, so that the connector is plugged. In the case that the connector is difficult for a person to reach, the device provides convenience for the plugging work of the connector. When a large number of connectors are closely inserted on a panel, the space left on the panel for manually grabbing the connector is small. If a person manually plugs the connector on the panel, the other connectors around the connector need to be unplugged in advance, so that the plugging work can be normally performed, which also increases the workload and the failure probability of the equipment. The connector auxiliary plugging device provided in the embodiment can directly reach into a large number of connectors to clamp a specified connector to complete plugging.

[0069] In the embodiment, in order to ensure the feasibility of the movement of the sliding nut 211 on the transmission screw rod 11, the sliding nut 211 needs to be able to move a certain distance relative to the fixed shaft 3. Therefore, the structure of the sliding nut 211 on the transmission end 21 in the embodiment also involves the following design:

[0070] As shown in Figure 4 , the transmission end 21 has two oppositely arranged butt joints 212, and the two butt joints 212 are each provided with a sliding groove 213. The sliding grooves 213 of the two butt joints 212 face each other inward. The sliding nut 211 is arranged between the two butt joints 212, and the sliding grooves 213 of the two butt joints 212 are in sliding cooperation with the sliding nut 211. It should be noted that Figure 4 , in order to facilitate the display of the structure of the internal sliding groove 213 of the transmission end 21, the sliding nut 211 in one of the transmission ends 21 is hidden, and the arrow on the sliding nut 211 in the other transmission end 21 represents the direction in which the sliding nut 211 can move on the sliding groove 213.

[0071] In the embodiment, the two butt joints 212 are respectively located on the two sides of the transmission end 21, and a certain distance exists between the two butt joints 212, which is used to accommodate the sliding nut 211.

[0072] As shown in Figure 4 and Figure 5 , the sliding nut 211 comprises a main body part 2111 and two sliding platform parts 2112, wherein:

[0073] The two sliding platform parts 2112 are respectively arranged on the two sides of the main body part 2111. One of the sliding platform parts 2112 is in sliding cooperation with the sliding groove 213 of one of the butt joints 212, and the other sliding platform part 2112 is in sliding cooperation with the sliding groove 213 of the other butt joint 212. The main body part 2111 is located between the two butt joints 212.

[0074] AsFigure 4 and Figure 5 As shown, in this embodiment, the slide portion 2112 can be cylindrical, and the slide portions 2112 on both sides of the main body 2111 need to be coaxial. This is because when the sliding nut 211 slides on the transmission screw 11, the angle of the sliding nut 211 itself relative to the transmission screw 11 will not change, but the angle of the transmission end 21 of the caliper body 2 relative to the transmission screw 11 will change. The slide portion 2112 is set to be cylindrical, and the docking portion 212 will rotate at a smaller angle with the slide portion 2112 as the center. The length of the slide 213 determines the distance that the sliding nut 211 can slide on the transmission end 21, which indirectly determines the maximum distance that the two clamping ends 22 can be separated. In actual scenarios, the length of the slide 213 and the length of the transmission screw 11 can be designed according to the specifications of commonly used connectors, so that the connector auxiliary plug-in device can adapt to more types of connectors.

[0075] like Figure 4 and Figure 5 As shown, a threaded hole 2113 is provided on the main body 2111, and the threaded hole 2113 passes through the main body 2111 and is threadedly connected to the transmission screw 11; among the two sliding nuts 211, the threaded hole 2113 of one sliding nut 211 is threadedly connected to the forward wire 111, and the threaded hole 2113 of the other sliding nut 211 is threadedly connected to the reverse wire 112;

[0076] In this embodiment, the sliding nuts 211 on the two pliers bodies 2 can be of the same model and size. The two sliding nuts 211 of the same model are respectively sleeved on the forward wire 111 and the reverse wire 112. When the transmission screw 11 rotates, the two sliding nuts 211 cannot rotate synchronously with the transmission screw 11, and can only move along the forward wire 111 and the reverse wire 112 respectively. Since the rotation directions of the forward wire 111 and the reverse wire 112 are opposite, the moving directions of the two sliding nuts 211 are also opposite.

[0077] It is worth mentioning that since the relative movement distance of the two sliding nuts 211 on the transmission screw 11 determines the opening and closing angle between the transmission ends 21 of the two pliers 2, and thus also determines the opening and closing angle between the clamping ends 22 of the two pliers 2, the relative distance between the two sliding nuts 211 can be customized to determine the opening and closing size between the clamping ends 22 of the two pliers 2, so that the opening and closing size between the clamping ends 22 of the two pliers 2 can just correspond to connectors of different models and sizes, thereby realizing the grasping of connectors of various models and sizes.

[0078] like Figure 6As shown, in the embodiment, in order to improve the adaptability between the clamping end 22 of the clamp body 2 and the connector, and to avoid damage to the connector during clamping, the clamping end 22 of each clamp body 2 is provided with an adaptive clamp 221, and the connector is clamped by the cooperation between the two adaptive clamps 221.

[0079] In the embodiment, the two adaptive clamps 221 are arranged on the same side of the two clamping ends 22, and the shape profile of the adaptive clamp 221 matches the connector, for example, the outer profile of the connector is arc-shaped, and the shape of the adaptive clamp 221 is also arc-shaped.

[0080] Further, a rotating handle can be arranged at one end of the transmission screw rod 11, and the transmission screw rod 11 is driven to rotate forward or reversely by rotating the rotating handle manually, so that the two sliding nuts 211 on the transmission screw rod 11 move towards each other or move away from each other, thereby realizing the opening and closing of the clamping ends 22 of the two clamp bodies 2.

[0081] For example, when the connector needs to be clamped, the rotating handle is rotated to drive the transmission screw rod 11 to rotate, so that the two sliding nuts 211 on the transmission screw rod 11 move towards each other, the clamping ends 22 of the two clamp bodies 2 are opened, the connector is placed between the clamping ends 22 of the two clamp bodies 2, and then the rotating handle is reversely rotated to drive the transmission screw rod 11 to reversely rotate, so that the two sliding nuts 211 on the transmission screw rod 11 move away from each other, and the clamping ends 22 of the two clamp bodies 2 close inward to clamp the connector.

[0082] In the embodiment, an external housing can also be arranged, part of the clamp body 2 on the transmission end 21 side and the fixed shaft 3 are arranged inside the external housing, the transmission screw rod 11 is arranged inside the external housing, one end of the transmission screw rod 11 extends out of the side surface of the external housing and the rotating handle is arranged, the clamping ends 22 of the two clamp bodies 2 extend out of the end surface of the external housing, and the external housing can better protect the transmission assembly 1 and the clamp body 2 and facilitate manual holding. The rotating handle arranged on the side surface of the external housing is manually rotated by hand, and the opening and closing of the clamping ends 22 of the two clamp bodies 2 can be controlled.

[0083] Embodiment 2:

[0084] The embodiment is based on the embodiment 1, and provides another connector auxiliary plugging device. Different from the aforementioned embodiment 1, the transmission assembly 1 is optimized in the embodiment to facilitate single-handed operation.

[0085] The structure design of the transmission assembly 1 and the clamp body 2 in the connector auxiliary plugging device provided in the embodiment can refer to the embodiment 1, and will not be described in detail here.

[0090] In the embodiment, the rotation direction of the output shaft of the motor 12 can be defined, so as to drive the worm 13 to rotate in different directions, and then drive the worm gear 14 and the transmission screw rod 11 to rotate in different directions, so as to realize the back-to-back movement or the opposite movement of the sliding nuts 211 of the two clamp bodies 2.

[0091] In order to make the connector auxiliary plugging device more convenient to use in actual use, facilitate the artificial holding and use of the connector auxiliary plugging device, and protect the transmission assembly 1 in the device, the embodiment further relates to the following design:

[0097] Example 3:

[0098] This embodiment, based on Embodiments 1 and 2, provides a method for using a connector auxiliary plugging and unplugging device, which is applied to the connector auxiliary plugging and unplugging device described in Embodiment 1 or 2, including:

[0099] The connector auxiliary plug-in device can be used not only to unplug the connector, but also to plug in the connector. When the connector needs to be unplugged, the transmission screw 11 is first driven to rotate so that the two clamping ends 22 are separated until the distance between the two clamping ends 22 is greater than the width of the connector. Then, when the connector is clamped, Figure 11 As shown, the method flow includes:

[0100] In step 101 , the connector is placed between two clamping ends 22 .

[0101] In step 102 , the transmission screw 11 rotates in a first preset direction, driving the two sliding nuts 211 to move in opposite directions on the transmission screw 11 , so that the clamping ends 22 of the two pliers bodies 2 are closed.

[0102] In the embodiment, the first preset direction needs to be determined according to the positive wire 111 and the reverse wire 112 on the transmission screw rod 11 and the thread rotation direction on the sliding nut 211, and it needs to be ensured that when the transmission screw rod 11 rotates in the first preset direction, the two sliding nuts 211 on the transmission screw rod 11 move away from each other, and when the transmission screw rod 11 rotates in the direction opposite to the first preset direction, the two sliding nuts 211 on the transmission screw rod 11 move towards each other.

[0103] In step 103, the two clamping ends 22 are relatively closed to clamp the connector.

[0104] When the connector needs to be inserted, first, the connector is clamped according to steps 101 and 102, then the connector is inserted into the corresponding position, and finally the clamped connector is released. As shown in the figure, the specific method flow includes: Figure 12

[0105] In step 201, the transmission screw rod 11 rotates in the second preset direction to drive the two sliding nuts 211 to move towards each other on the transmission screw rod 11, so that the clamping ends 22 of the two clamp bodies 2 are separated.

[0106] In the embodiment, the second preset direction is opposite to the first preset direction.

[0107] In step 202, the two clamping ends 22 are relatively far away from each other to release the clamped connector.

[0108] The above only describes the preferred embodiment of the present application and is not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.​
