[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0028] Reference Figure 1-4An embodiment of the utility model provides an electric power system automation experimental device that is easy to maintain. The device includes multiple functional sockets 1, such as the wiring terminals of relays, the wiring terminals of contact switches, the wiring terminals of protectors, the wiring terminals of various indicator lights, and the wiring ports of some other components. The device also has an exterior and an interior. Specifically, in this embodiment, the device is based on an operating table 9. The exterior refers to the part outside the operating table 9, and the interior refers to the part inside the operating table 9. Based on this, the utility model also has the following parts:

[0029] The movable parts 2 are consistent in number with the functional sockets 1 and correspond to them. The movable parts 2 have conductive characteristics, and the corresponding movable parts 2 and the functional sockets 1 have an electrically conductive relationship, such as Figure 1 As shown in , for the convenience of identification by the operator, the side of the function socket 1 and the movable part 2 are provided with numbers, and the corresponding function socket 1 has the same number as the movable part 2, and at least a part of the movable part 2 is located outside the operating table 9 and can be moved;

[0030] The first linear guide 3 has a conductive feature. For example, the first linear guide 3 can be a copper rod or other metal rod. The first linear guide 3 is arranged inside the operating table 9. There are multiple first linear guides 3. The specific number is roughly consistent with the number of wires matched with the device in the prior art. In terms of positional relationship, when the movable part 2 is moving, it can keep in contact with different first linear guides 3 when it moves to different positions, so as to achieve mutual conduction. In order to facilitate the accurate positioning of the first linear guide 3 outside the operating table 9, a plurality of marking lines are arranged outside the operating table 9, which are respectively close to and parallel to the positions of the plurality of first linear guides 3, and the ends of the marking lines are correspondingly provided with numbers;

[0031] According to the above, when the operator conducts a wiring experiment through the utility model, for example, when the wiring operation is to be performed between the No. 1 function socket 1 and the No. 12 function socket 1 in the figure, the No. 1 movable part 2 and the No. 12 movable part 2 are moved to the same first linear guide 3. If the No. 1 movable part 2 is moved to the L3 mark, the No. 12 movable part 2 can be moved to the L3 mark in the same way, that is, the electrical connection between the No. 1 function socket 1 and the No. 12 function socket 1 is achieved, thereby eliminating the configuration of the external wire on the operating table 9. Therefore, compared with the traditional experimental device, in the utility model, directly through the first linear guide 3 is equivalent to the traditional wire being built-in inside the operating table 9, so that the number of corresponding external scattered experimental equipment is reduced, avoiding daily loss, so the device cost is lower, and at the same time, it can ensure the cleanliness of the table during the experiment and reduce the mess. As for the wires of consumables, their number is reduced or they are directly not required to cooperate, which can reduce or get rid of the tediousness of daily maintenance to a greater extent;

[0032] In addition, in order to further improve the practicality of the utility model, in the utility model, although the functional sockets 1 are electrically connected through the first linear guide 3, the functional sockets 1 can still retain the traditional plug-in function in terms of appearance structure to prevent damage to the internal first linear guide 3 or the movable part 2. It is still possible to use traditional external wires for connection to maintain the diversity of the functions of the utility model.

[0033] Further, see Figure 3 and Figure 4 Regarding the conduction mode between the movable part 2 and the functional socket 1, the utility model also includes a second linear guide 4, the number of which is consistent with the movable part 2, and they correspond respectively, and are in an electrically conductive relationship. For example, the second linear guide 4 can be electrically connected to the corresponding functional socket 1 using a built-in circuit. The second linear guide 4 is arranged inside the operating table 9. The moving path of the movable part 2 is linear, and it moves along the second linear guide 4. At least a part of the movable part 2 is located inside the operating table 9 and contacts with the corresponding second linear guide 4, so that during the movement of the movable part 2, the second linear guide 4 can ensure that it is in a stable conductive state with the corresponding functional socket 1. The second linear guide 4 can also use components such as copper rods or other types of metal rods.

[0034] Further, see Figure 3-5 The movable part 2 includes a touch end 201 and a conductive end 202, which are fixedly connected. The touch end 201 is located outside the operating table 9 and has an insulating property. For example, the touch end 201 can be made of insulating materials such as plastic or wood. The touch part and the operating table 9 are slidably matched, and a corresponding slide groove is provided on the operating table 9. The conductive end 202 is located inside the operating table 9 and has a conductive property. For example, the conductive end 202 can be made of metal materials such as copper or iron. The conductive end 202 is in contact with the second linear guide 4, thereby maintaining a conductive relationship with the second linear guide 4. When the movable part 2 moves as a whole, it contacts the first linear guide 3 through the conductive end 202; through the combination setting between the conductive end 202 and the touch end 201, after the operating table 9 is powered on, when a person touches the movable part 2, it is not easy to cause electric shock, which helps to improve the safety of the utility model.

[0035] Further, see Figure 5 Regarding the contact mode between the second linear guide 4 and the conductive end 202, the second linear guide 4 directly moves through the conductive end 202, so that the conductive end 202 forms a sleeve relationship with the second linear guide 4. When it moves, it moves along the path of the second linear guide 4, thereby further improving the stability of the entire movable part 2 when moving.

[0036] Further, see Figure 1-3 Regarding the area layout outside the operating table 9, specifically, the outside of the operating table 9 at least includes a functional area 5 and an operating area 6. The functional area 5 is a longitudinal structure, and the operating area 6 is a planar structure. The movable part 2 is located on the operating area 6, so that it is convenient for the experimenter to operate the movable part 2. The functional socket 1 is located on the functional area 5, so as to be separated from the movable part 2 to prevent interference with the operation of the personnel, and at the same time help to keep the entire outer surface of the operating table 9 clean.

[0037] Further, see Figure 1-3 A bearing portion 7 is also provided at the functional area 5, which is used to carry some equipment needed in the experiment, such as motors, resistors, switches and various electric meters. When the equipment is placed on the bearing portion 7, its wiring terminal can be directly plugged into the functional socket 1 to be connected. The bearing portion 7 can provide a place for these devices to facilitate experimental operations.

[0038] Further, see Figure 1-3 The bearing portion 7 is retractable and arranged in the functional area 5. For example, the bearing portion 7 can adopt a bearing frame, which is slidably arranged on the surface of the functional area 5 and can be pushed into the interior of the operating table 9 when stored. Figure 1 and Figure 2 In the state shown, when in use, the carrier can be pulled out to the outside of the operating table 9, that is, Figure 3 The state shown helps to further maintain the neatness of the appearance of the device by being foldable.

[0039] Further, see Figure 2 The operation area 6 may also include a first side area 601 and a second side area 602, which are respectively Figure 2 On the left side and the right side of the viewing angle, the movable part 2 is located in the first lateral area 601, and the second lateral area 602 is provided with a plurality of groups of plug interfaces 8, each group can have two or more than two. The inner ends of the plug interfaces 8 penetrate into the operating table 9 and face the first linear guide 3. When more devices need to be connected to the functional socket 1, the devices can be directly placed in the second lateral area 602, and their wiring terminals are inserted into the plug interfaces 8, so as to make contact and conduction with the first linear guide 3, so that the devices can be connected to the functional socket 1 with the help of the first linear guide 3, thereby further improving the practicability of the device.

[0040] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
