[0024] In the following example, the direction is indicated by the arrow direction in the drawing plane in Fig. 1 defined.

[0025] As in Fig. As shown in Figures 1 to 4, the present embodiment provides a connector device for a drawer of a control cabinet, which comprises a first bracket 1, a second bracket 2, and a third bracket 3. The first bracket 1 is mounted on the cabinet body of the control cabinet, and the third bracket 3 is mounted in the drawer of the control cabinet.

[0026] The first holder 1 comprises a first holder body 11, a first locking hole 12 provided in the first holder body 11, and first guide holes 13, wherein a first insert combination is inserted into the first locking hole 12 and the first guide holes 13 are arranged distributed in a diagonal direction.

[0027] The second bracket 2 comprises a second bracket body 21, a second locking hole 22 provided in the second bracket body 21, and first guide rods 23 that fit the first guide holes 13. A second insert combination is inserted into the second locking hole 22, and the first guide rods 23 are also arranged in a diagonal direction. The first guide holes 13 have sections extending toward the first guide rods 23.

[0028] The third bracket 3 comprises a third bracket body 31 and a through hole 33 provided in the third bracket body 31. The through hole 33 is provided with guide parts 34 on its left and right sides facing the second bracket 2, and guide grooves 26 matching the guide parts 34 are provided on an outer side of the second locking hole 22.

[0029] In this embodiment, a damping mechanism is provided between the third bracket 3 and the second bracket 2, the damping mechanism comprising: second guide rods 24 provided on a side of the second bracket 2 facing away from the first guide rods 23, the second guide rods 24 being arranged distributed in a different diagonal direction than the first guide rods 23; second guide holes 32 provided on the third bracket 3 and matching the second guide rods 24, the second guide holes 32 having portions extending away from the second guide rods 24 such that the second guide rods 24 each penetrate into the second guide holes 32 with an upper part and are movable back and forth within the second guide holes 32;and elastic elements 25, each mounted on the second guide rods 24, wherein the elastic element 25 is, for example, a spring.;

[0030] In this exemplary embodiment, the damping mechanism serves to realize a movement of the third holder 3 relative to the second holder 2. Since the drawer of the control cabinet has three position states, i.e. a disconnected position, a test position, and an operating position, when the drawer moves from the disconnected position to the operating position, the first holder 1 is held stationary with the cabinet body, and the first guide rods 23 on the second holder 2 penetrate the first guide holes 13 and can move along the first guide holes 13, so that the first holder 1 is connected to the second holder 2 and the first insert combination and the second insert combination are pluggably connected to one another. The second holder 2 together with the third holder 3 follows the movement of the drawer and reaches the test position first, with the second holder 2 remaining stationary relative to the first holder 1.With the further movement of the drawer toward the cabinet body, the guide parts 34 on the two sides of the through hole 33 move along the guide grooves 26 on the two sides of the second locking hole 22. At the same time, the elastic elements 25 in the damping mechanism are elastically deformed by compression, so that the third bracket 3 moves further toward the cabinet body relative to the second bracket 2 under the action of the elastic elements 25 and finally reaches the operating position.

[0031] In this embodiment, the through hole 33 can be placed on the outside of the second locking hole 22 so that the guide parts 34 on the two sides of the through hole 33 and the guide grooves 26 on the two sides of the second locking hole 22 fit together.

[0032] In this embodiment, a limiting mechanism is provided between the second bracket 2 and the third bracket 3.

[0033] As in Fig. 4, in one embodiment of this embodiment, the limiting mechanism includes: a first locking groove 221 provided at a front side of the second locking hole 22; a second locking groove 222 provided at a rear side of the second locking hole 22; and a cover plate 27 provided at a side of the second locking hole 22 facing the third bracket 3. A limiting portion is formed between the cover plate 27 and the first locking groove 221 and the second locking groove 222. Accordingly, a first locking projection 331 is provided at a front side of the through-hole 33, which fits the first locking groove 221, and a second locking projection 332 is provided at a rear side of the through-hole 33, which fits the second locking groove 222. In order to avoid the second insert combination, two first locking grooves 221 are provided on the left side and the right side, i.e.An escape opening is provided between the two first locking grooves 221. Accordingly, two first locking projections 331 are also provided on the left and right sides. Only one second locking groove 222 and only one second locking projection 332 are provided. It should be understood that the cover plate 27 is also provided with an opening corresponding to the escape opening and is secured by a screw to the upper part of the second locking hole 22.

[0034] In the following, in connection with the Fig. 1 to 3, an operation process of the connector device according to this embodiment is described, in which the connector device transitions from the state in the disconnection position to the state in the test position and then to the state in the operation position.

[0035] In Fig. In the state shown in Figure 1 in the separation position, the third bracket 3 is fixed to the second bracket 2 by the limiting mechanism, so that when the third bracket 3 moves with the drawer toward the cabinet body, the first guide rods 23 are first inserted into the first guide holes 13 and cause the second bracket 2 to move relative to the first bracket 1. This realizes a primary guiding function. In this process, the first insert combination and the second insert combination are inserted into each other in position, thus realizing a firm connection. Then, the connector device is in the position shown in Fig. 2 in the test position and the second bracket 2 is brought into reliable connection with the first bracket 1. In this case, a limitation is realized by a locking connection between the first locking projections 331 and the second locking projection 332 of the limiting mechanism and the cover plate 27, and the movement of the third bracket 3 relative to the second bracket 2 is prevented. With the further movement of the drawer towards the cabinet body, the guide parts 34 on the two sides of the through hole 33 move along the guide grooves 26 on the two sides of the second locking hole 22. In this case, the elastic elements 25 in the damping mechanism are compressed, so that the third bracket 3 moves further towards the cabinet body relative to the second bracket 2 under the action of the elastic elements 25.In this case, the first locking projections 331 and the second locking projection 332 detach from the boundary of the cover plate 27 and move along the first locking grooves 221 and the second locking groove 222 toward the second bracket 2, and the second guide rods 24 move through the second guide holes 32 in the opposite direction, finally achieving the position shown in . Fig. 3 shown state is realized in the operating position.

[0036] As in Fig. 8, in another embodiment of this exemplary embodiment, the limiting mechanism comprises a limiting part 35 arranged on an upper part of the second guide rod 24, wherein a mutually limiting contact surface is formed between the limiting part 35 and the second guide hole 32. For example, the limiting part 35 comprises a screw with an external thread, wherein the upper part of the second guide rod 24 is provided with an internal thread matching the external thread. Alternatively, a washer can be provided between the screw and the second guide hole 32, wherein a limiting mechanism is formed between the screw and / or the washer and the upper part of the second guide hole 32. For example, the limiting part 35 can be fastened to the upper part of the second guide hole 32 by riveting or in some other way.

[0037] In the following, in connection with the Fig. 5 to 7, an operation process of the connector device in another embodiment of this embodiment is described, in which the connector device transitions from the state in the disconnection position to the state in the test position and then to the state in the operation position.

[0038] In Fig. In the state shown in Figure 5 in the separation position, the third bracket 3 is limited by the limiting part 35 on the upper part of the second guide rod 24 on the second bracket 2. During the movement of the third bracket 3 with the drawer towards the cabinet body, the first guide rods 23 are first inserted into the first guide holes 13 and cause the second bracket 2 to move relative to the first bracket 1. This realizes a primary guiding function. In this process, the first insert combination and the second insert combination are inserted into each other in position, thus realizing a firm connection. Then, the connector device is in the position shown in Fig. 6 in the test position and the second bracket 2 is brought into reliable connection with the first bracket 1. At this time, the movement of the third bracket 3 relative to the second bracket 2 is prevented by the limiting part 35 and / or the washer of the limiting mechanism provided on the upper part of the second guide rod 24. With the further movement of the drawer towards the cabinet body, the guide parts 34 on the two sides of the through hole 33 move along the guide grooves 26 on the two sides of the second locking hole 22. At this time, the elastic elements 25 in the damping mechanism are compressed, so that the third bracket 3 moves further towards the cabinet body relative to the second bracket 2 under the action of the elastic elements 25.In this case, the limiting member 35 and / or the washer detach from the upper part of the second guide hole 32, and the second guide rod 24 moves through the second guide hole 32 in the opposite direction, finally achieving the position shown in . Fig. 7 shown state is realized in the operating position.

[0039] In the above embodiments, the first insert combination and the second insert combination refer to a combination of multiple insert modules, which can be either an assembly of a single insert module or an additional assembly of 2 to 6 insert modules to enable flexible adaptation to market power or signal requirements. At the same time, in the present application, the strength of the elastic potential energy of the elastic element can be flexibly changed to adapt to a different number of insert modules. Furthermore, the customer is offered a greater assembly tolerance within the compression stroke of the elastic element, which in turn protects the insert.

[0040] Obviously, the above-described embodiments of the present application are merely examples to clearly illustrate the present application and are not intended to limit the embodiments of the present application. Those skilled in the art may also make other changes or modifications in various forms based on the above description. It would not be necessary or possible to exhaustively list all embodiments.
