[0001] This utility model relates to the field of power distribution control connection technology, and specifically to a device for preventing mis-insertion of power distribution control equipment connections. Background Technology

[0002] Power distribution control equipment refers to the equipment system used for controlling, protecting, measuring, and communicating in a power system. It is mainly used to regulate various electrical parameters such as current and voltage to ensure the safe, stable, and economical operation of the power system.

[0003] In the existing power distribution control equipment connection process, connectors are used for connection. A connector consists of a male connector and a female connector. The male connector is inserted into the female connector to make electrical connections on the power distribution control equipment. Since there are many connectors on the power distribution control equipment, construction workers may mis-insert the male connector and female connector during the insertion process, which will affect the connection accuracy and safety of the power distribution control equipment. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a device to prevent mis-insertion of power distribution control equipment connections, in order to solve the technical problem that there are many connectors on existing power distribution control equipment, and construction personnel may mis-insert the male and female connectors during the connection process, thereby affecting the connection accuracy and safety of the power distribution control equipment.

[0005] According to the technical solution provided in the embodiments of this application, a mis-insertion prevention device for power distribution control equipment connection includes a mis-insertion prevention component and a connector. The mis-insertion prevention component is installed on the male connector and the female connector on the connector and is used to limit mis-insertion of the male connector and the female connector.

[0006] The anti-misinsertion component includes a limiting mechanism and a limiting seat. The limiting mechanism is vertically installed in the first mounting groove on the female connector, and the limiting seat is vertically installed in the second mounting groove on the male connector. The limiting rod on the limiting mechanism is engaged in the connecting groove on the limiting seat for fixing the matching male connector during insertion.

[0007] A limiting bolt is vertically installed on the top of the limiting female seat on the limiting mechanism. Its bottom abuts against the slider installed in the moving groove of the limiting female seat. The limiting rod is installed in the middle of the bottom of the slider so that the limiting rod is fixed in the insertion groove on the connecting female seat and is used to limit the mismatch of the connecting male head in the insertion connection.

[0008] Furthermore, the limiting mechanism includes a limiting rod, a slider, and a limiting female seat. The limiting female seat has a cylindrical structure and a moving groove is provided inside the limiting female seat. The slider is slidably installed in the moving groove, and the limiting rod is installed at the bottom of the slider, so that the slider moves along the vertical direction of the moving groove, thereby driving the limiting rod to move along the vertical direction.

[0009] Furthermore, the limiting mechanism also includes an elastic element, which is installed on the top of the slider within the moving groove for elastic support of the slider.

[0010] Furthermore, a mounting base is provided on the top of the limiting female seat, and the limiting bolt is screwed into the mounting base.

[0011] Furthermore, the top two sides of the limiting rod are provided with corresponding inclined surfaces.

[0012] Furthermore, the female connector has three parallel and spaced positioning strips in its insertion slot, and the male connector has three corresponding positioning slots, with each positioning strip engaging in its corresponding positioning slot.

[0013] Furthermore, the limiting bolt, limiting female seat, limiting rod, and limiting seat are all made of insulating material.

[0014] In summary, the beneficial effects of this application are as follows:

[0015] 1. By setting an anti-misinsertion component on the connector, the limiting bolt on the anti-misinsertion component is screwed onto the mounting base on the limiting female seat. Rotating the limiting bolt causes it to move downward, thereby abutting the slider installed in the moving groove, limiting the slider to the limiting female seat. This, in turn, fixes the limiting rod connected to the bottom of the slider in the insertion groove, thereby limiting the male connector in the insertion connection and preventing male connectors of different models or functions from being mistakenly inserted into the female connector, thus improving the anti-misinsertion efficiency of power distribution control equipment connections.

[0016] 2. By setting an anti-misfit component on the connector, the limiting mechanism on the anti-misfit component is installed on the female connector, and the limiting seat is installed on the male connector. After the limiting bolt on the limiting mechanism moves upward, the corresponding male connector is inserted into the female connector. At the same time, the limiting rod on the limiting mechanism is engaged in the connecting groove on the limiting seat. By rotating the limiting bolt, the limiting bolt moves downward, limiting the movement of the limiting rod, thereby limiting and fixing the male connector after insertion, preventing the male connector from loosening after insertion, and thus improving the connection stability of the power distribution control equipment.

It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0025] A device for preventing mis-insertion of power distribution control equipment, the structure of which is as follows: Figures 1-4As shown, the device includes an anti-mis-mating component 100 and a connector 200. The anti-mis-mating component 100 is mounted on the male connector 210 and the female connector 220 of the connector 200 to limit mis-mating of the male connector 210 and the female connector 220 during insertion. The anti-mis-mating component 100 includes a limiting mechanism 110 and a limiting seat 120. The limiting mechanism 110 is vertically mounted in a first mounting groove 221 on the female connector 220, while the limiting seat 120 is vertically mounted in a second mounting groove 211 on the male connector 210. The limiting rod 111 on the limiting mechanism 110 is engaged with the limiting seat 120. The connecting groove 121 is used to fix the matching male connector 210 in the plug-in connection; the limiting bolt 130 is vertically installed on the top of the limiting female seat 113 on the limiting mechanism 110, and its bottom abuts against the slider 112 installed in the moving groove of the limiting female seat 113. The bottom of the slider 112 is equipped with a limiting rod 111, so that the limiting rod 111 is vertically fixed in the plug-in groove 222 on the connecting female seat 220, limiting the mismatched male connector 210 in the plug-in connection, preventing the mismatched male connector 210 from being plugged into the connecting female seat 220, thereby affecting the connection accuracy of the power distribution control equipment.

[0026] As a preferred embodiment, please refer to Figure 3 and Figure 4 The limiting mechanism 110 includes a limiting rod 111, a slider 112, and a limiting female seat 113. The limiting female seat 113 has a cylindrical structure and a moving groove inside. The moving groove also has a cylindrical structure. The slider 112 also has a circular structure and is slidably installed in the moving groove. The limiting rod 111 is installed at the bottom of the slider 112 so that when the limiting bolt 130 is rotated, the slider 112 is pushed to move vertically along the moving groove, thereby driving the limiting rod 111 to move vertically so that the limiting rod 111 is inserted into the insertion groove 222. This limits the insertion of the male connector 210 during the insertion process and prevents male connectors 210 with different functions from being mistakenly inserted into the female connector 220.

[0027] As a preferred embodiment, please refer to Figure 4The limiting mechanism 110 also includes an elastic element 114, which is a metal spring. The elastic element 114 is installed on the top of the slider 112 in the moving groove so that after the limiting bolt 130 rotates and moves upward, it releases the fixation on the slider 112. When the matching male connector 210 is inserted into the female connector 220, the limiting rod 111 pushes the slider 112 to move upward along the moving groove, compressing the metal spring of the elastic element 114. When the male connector 210 is inserted into place, the compressed metal spring of the elastic element 114 is released, thereby pushing the elastically abutting slider 112 to move downward along the moving groove, thereby pushing the limiting rod 111 installed at the bottom of the slider 112 to move vertically and enter the connecting groove 121 on the limiting seat 120, thereby limiting the matching male connector 210 and preventing the male connector 210 from loosening.

[0028] As a preferred embodiment, please refer to Figure 4 The top of the limiting female seat 113 is also provided with a mounting seat 115, and the limiting bolt 130 is screwed into the mounting seat 115 so that the limiting bolt 130 rotates down and up along the screw hole on the mounting seat 115, thereby fixing and loosening the slider 112 in the limiting female seat 113.

[0029] As a preferred embodiment, please refer to Figure 4 The top two sides of the limiting rod 111 are provided with corresponding inclined surfaces. By providing corresponding inclined surfaces at the bottom of the limiting rod 111, the limiting rod 111 can be easily engaged into the connecting groove 121 and moved out of the connecting groove 121, thereby improving the anti-misinsertion efficiency and fixing efficiency of the limiting rod 111.

[0030] As a preferred embodiment, please refer to Figure 4 The female connector 220 has three parallel and spaced positioning strips 223 in the insertion slot 222, while the male connector 210 has three corresponding positioning slots 212. Each positioning strip 223 engages with the corresponding positioning slot 212 so that the male connector 210 is positioned and engaged in the female connector 220, preventing inaccurate insertion during the matching process of the male connector 210.

[0031] As a preferred embodiment, please refer to Figure 1 and Figure 2 The limiting bolt 130, the limiting female seat 113, the limiting rod 111, and the limiting seat 120 are all made of insulating material, thereby improving the safety of the anti-misinsertion device.

[0032] The working principle of the anti-misinsertion device for power distribution control equipment connection of this utility model is as follows:

[0033] During the insertion process of the connector 200 for power distribution control equipment, to prevent different types or functions of male connectors 210 from being mistakenly inserted into the female connector 220, an anti-misinsertion component 100 is provided on the connector 200. The limiting mechanism 110 on the anti-misinsertion component 100 is installed in the first mounting groove 221 of the female connector 220, while the limiting seat 120 is installed in the second mounting groove 211 of the male connector 210. A limiting bolt 130 is screwed onto the mounting seat 115 on the limiting female connector 113. Rotating the limiting bolt 130 causes it to move downwards, thereby abutting against the slider 112 installed in the moving groove. This limits the slider 112 to the limiting female connector 113, fixing the limiting rod 111 connected to the bottom of the slider 112 in the insertion groove 222. This limits the insertion of the male connector 210 during the connection, preventing different types or functions from being mistakenly inserted into the female connector 220. To prevent the mis-insertion of male connectors 210 of different models or functions into female connectors 220, the anti-mis-insertion efficiency of power distribution control equipment is improved. Simultaneously, when male connectors 210 of the same model are inserted into female connectors 220, the limiting bolt 130 is rotated to release the limiting rod 111 from the limiting mechanism 110, allowing the male connector 210 to be inserted into the female connector 220. After insertion, the limiting bolt 130 on the anti-mis-insertion assembly 100 is rotated to move the limiting bolt 130 downwards, thereby abutting the slider 112 installed in the moving groove. This causes the slider 112 to be limited on the limiting female connector 113, fixing the limiting rod 111 connected to the bottom of the slider 112 within the insertion groove 222. This limits and fixes the inserted male connector 210, preventing it from loosening after insertion and improving the connection stability of the power distribution control equipment.

[0034] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and solutions employed. Furthermore, the scope of the utility model involved in this application is not limited to the specific combination of the above-described technical features, but should also cover other technical solutions formed by any combination of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
