[0003] In the related art, the connector includes a socket and a plug. The socket includes a female contact body, female pins and short-circuit elastic pieces.

The male contact body is provided with male pins that cooperate with the female pins, and an insulating spacer is provided between adjacent male pins; when the male contact core is inserted into the female contact core, the insulating spacer of the male contact core is inserted into the contact joint of the two short-circuit elastic pieces to disconnect the originally short-circuited two female pins, so as to realize normal signal or power transmission; in this way, the switching between the short-circuit and open-circuit states is realized, so as to ensure that the voltage circuit is not short-circuited and the current circuit is not open-circuited.

[0038] The realization, functional features and advantages of the purpose of the present utility model will be further described with reference to the embodiments and the accompanying drawings. Specific embodiments

[0039] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0040] It should be noted that if there are directional indications (such as up, down, left, right, front, back,...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative positional relationship and movement conditions between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0041] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present utility model, the descriptions of "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, if "and / or" or "and / or" appears throughout the text, its meaning includes three parallel scenarios. Taking "A and / or B" as an example, it includes scenario A, scenario B, or the scenario where both A and B are satisfied simultaneously. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0042] The connector is applied to power grid base stations, etc., and has a long service life. After the short - circuit spring piece inside the connector has been in a working state for a long time, it may be worn or displaced, resulting in poor contact, etc. There may be a situation of self - short - circuit failure, which will increase the risk of electric shock for staff during maintenance, replacement, and inspection.

[0043] To solve the above problems, the present utility model proposes a plug module.

[0044] Please refer to Figures 1 to 3 In an embodiment of the present utility model, the plug module 100 is applied to a connector. The plug module 100 includes a plug body 110, at least two plug contacts 120, and at least two contact components 130. The plug body 110 is provided with an installation cavity 111 and at least two first short - circuit holes 112. The two first short - circuit holes 112 are respectively communicated with the installation cavity 111; the two plug contacts 120 are installed in the installation cavity 111; the two contact components 130 are both installed in the installation cavity 111. Each contact component 130 includes a first short - circuit spring piece 131 and a second short - circuit spring piece 132 connected to the first short - circuit spring piece 131, and each second short - circuit spring piece 132 is correspondingly arranged with a first short - circuit hole 112; the ends of the two first short - circuit spring pieces 131 away from the second short - circuit spring pieces 132 are in contact and conduct electricity with each other. Each contact component 130 is fixedly connected to a plug contact 120; each first short - circuit hole 112 is for inserting a contact end of a pin short - circuit piece 300 and contacting and conducting electricity with a second short - circuit spring piece 132.

[0045] The plug contact 120 is used for mating and plugging conduction with the socket module 200. Each plug contact 120 includes a sleeve and a crown spring. The two sleeves are fixed in the installation cavity 111 of the plug body 110. The upper end of each sleeve is connected to a contact component 130, and each crown spring is arranged in a sleeve; the second short-circuit elastic piece 132 of each contact component 130 is fixedly connected to the sleeve of a plug contact 120.

[0046] For example, at the plug module end, when the plug module 100 is plugged into the socket module 200, the first short-circuit elastic pieces 131 of at least two contact components 130 are separated by the socket module 200. At this time, the pin short-circuiting piece 300 can be inserted from the first short-circuit hole 112 to contact the second short-circuit elastic piece 132, and the pin short-circuiting piece 300 is used to connect with the second short-circuit elastic piece 132, so that at least two contact components 130 can still be short-circuited. Similarly, the above function can also be realized at the socket module end. The pin short-circuiting piece 300 can be a longitudinal pin short-circuiting piece 300a or a transverse pin short-circuiting piece 300b.

[0047] When the plug module 100 is disconnected from the socket module 200, and it is detected that the two first short-circuit elastic pieces 131 in at least one installation cavity 111 can be normally contacted and conducted, the two first short-circuit elastic pieces 131 of the two contact components 130 are short-circuited by themselves without the separation of the socket module 200, so that the two contact components 130 are short-circuited. By inserting the pin short-circuiting piece from the first short-circuit hole 112 to contact the second short-circuit elastic piece 132, the double short-circuit function of the two contact components 130 is realized, preventing accidental personal injury in the case of misjudgment of the detection result or pseudo-normal working conditions during maintenance. It should be noted that by using the longitudinal pin short-circuiting piece 300a, at least two contact components 130 in the same installation cavity 111 are short-circuited, and by using the transverse pin short-circuiting piece 300b, at least two contact components 130 in different installation cavities 111 are short-circuited. Similarly, the above function can also be realized at the socket module end.

[0048] Further, when the plug module 100 is disconnected from the socket module 200, but it is detected that the two first short-circuit elastic pieces 131 or one of the first short-circuit elastic pieces 131 in at least one installation cavity 111 have abnormal conditions and cannot be used normally, even if the two first short-circuit elastic pieces 131 are not separated by the socket module 200 and cannot be short-circuited by themselves, at this time, the pin short-circuiting piece 300 can also be inserted from the first short-circuit hole 112 to contact the second short-circuit elastic piece 132, and the pin short-circuiting piece 300 is used to connect with the second short-circuit elastic piece 132, so as to realize the function of short-circuiting the two contact components 130 by inserting the pin short-circuiting piece from the first short-circuit hole 112 to contact the second short-circuit elastic piece 132 under the condition that the detection result is abnormal. Similarly, the above function can also be realized at the socket module end.

[0049] Subsequently, the maintenance personnel can carry out subsequent repair work according to the detection results of the detection instrument. The plug module 100 can be short-circuited with the second short-circuit elastic piece 132 through the pin short-circuit piece 300 to ensure that the repair process is not subject to electric shock, improving the repair safety of the maintenance personnel during the repair process.

[0050] From the above three situations, the present utility model adds a second short-circuit elastic piece 132 to the original contact component 130 and cooperates with the movably inserted pin short-circuit piece 300 to contact. In this way, regardless of whether the two first short-circuit elastic pieces 131 of the two contact components 130 are in contact or not, the two second short-circuit elastic pieces 132 can be in contact conduction with the two contact ends of the pin short-circuit piece 300, so as to connect the contact component 130 to the corresponding plug contact 120 to realize the double short-circuit function, ensuring the successful short-circuit of the contact component 130 of the plug module 100, improving the reliability of the short-circuit, reducing the electric shock risk, and thus significantly improving the use safety of the operator.

[0051] It should be noted that during the process of the socket module 200 being separated from the plug module 100, the contact time of the two first short-circuit elastic pieces 131 of the adjacent contact components 130 and the contact time of the two adjacent second short-circuit elastic pieces 132 can be simultaneous contact, or the two first short-circuit elastic pieces 131 can contact first or the two second short-circuit elastic pieces 132 can contact first. The contact of the two adjacent first short-circuit elastic pieces 131 or the contact of the two adjacent second short-circuit elastic pieces 132 can enable at least two contact components 130 to realize the short-circuit function.

[0052] Optionally, the contact component 130 and the plug contact 120 can be fixedly connected by various methods or structures, and can also be contact abutment. The specific connection method can be set according to actual needs, as long as it remains conductive with the plug contact 120.

[0053] In an embodiment, please refer to Figure 2 and Figure 3 , the plug body 110 is further provided with at least two first detection holes 113. The two first detection holes 113 are both communicated with the installation cavity 111 and are located between the two first short-circuit holes 112. The first short-circuit elastic piece 131 includes a first short-circuit portion 1311 and a maintenance portion 1312 connected to the first short-circuit portion 1311. The first short-circuit portion 1311 extends and bends from one end of the second short-circuit elastic piece 132 towards the direction close to the central axis of the installation cavity 111. The maintenance portion 1312 extends from the first short-circuit portion 1311 towards the direction close to the second short-circuit elastic piece 132. The maintenance portion 1312 is correspondingly arranged with the first detection hole 113, and the maintenance portion 1312 is used for contact conduction with the probe of the detection instrument.

[0054] In this embodiment, the first short - circuit portion 1311 extends and bends towards the central axis of the installation cavity 111, so that the first short - circuit portion 1311 forms a contact point similar to a cone, and two adjacent first short - circuit portions 1311 are in contact conduction through two contact points; and at the end of the first short - circuit portion 1311, an inspection portion 1312 extends towards the direction close to the second short - circuit elastic piece 132, that is, the inspection portion 1312 is formed by the reverse extension and bending of the first short - circuit portion 1311, so that the inspection portion 1312 can be easily aligned with the first detection hole 113; thus, when two adjacent first short - circuit portions 1311 are in contact conduction, the short - circuit function of the contact component 130 is realized. Subsequently, after the probe of the detection instrument is inserted into the installation cavity 111 from the first detection hole 113, the probe of the detection instrument can be in contact conduction with the inspection portion 1312 to detect the conductivity of the first short - circuit elastic piece 131, and further the conductivity of the contact component 130 is detected.

[0055] It should be noted that the shapes and contact methods of the first short - circuit portion 1311 and the inspection portion 1312 can be set according to actual needs. It can be set by bending to form convex points, and two convex points or multiple convex points are in stable abutting contact; it can also be set as a plate shape or other shapes to form a convex contact surface, and two contact surfaces are in contact; it can also connect and conduct two adjacent first short - circuit elastic pieces 131 by setting an intermediate connecting piece.

[0056] In one embodiment, two first short - circuit portions 1311 are in contact conduction at the position of the central axis of the installation cavity 111.

[0057] Such as Figure 2 and Figure 3 , two contact components 130 are arranged symmetrically left - and - right or front - and - back with the central axis of the installation cavity 111 as the center, so that the first short - circuit portions 1311 of the two first short - circuit elastic pieces 131 are in contact conduction at the position of the central axis of the installation cavity 111. The arrangement of the first short - circuit elastic piece 131 and the second short - circuit elastic piece 132 can be arranged horizontally side - by - side or vertically in the height direction, and the specific arrangement direction can be selected according to actual needs.

[0058] Such as Figure 3, in this embodiment, the first short - circuit elastic piece 131 and the second short - circuit elastic piece 132 are arranged in sequence along the horizontal direction, and the two contact components 130 are symmetrically arranged at the central axis position of the installation cavity 111. This design makes the contact position points of the two first short - circuit elastic pieces 131 both located in the insertion direction of the socket module 200, which facilitates directly separating the two mutually - contacting first short - circuit elastic pieces 131 while the plug module 100 is inserted into the socket module 200. In this way, the insertion action of the socket module 200 and the plug module 100 can be linked with the separation action of the two first short - circuit elastic pieces 131, thereby accelerating the disconnection speed of the two contact components 130.

[0059] In one embodiment, please refer to Figure 3 , each second short - circuit elastic piece 132 includes a connecting portion 1321 and two second short - circuit portions 1322. The two second short - circuit portions 1322 are connected to the connecting portion 1321, and the two second short - circuit portions 1322 are arranged oppositely and enclose a clamping position; the pin short - circuit member is inserted into the clamping position and is in contact conduction with the two second short - circuit portions 1322.

[0060] Specifically, the connecting portion 1321 extends from the first short - circuit portion 1311 of the first short - circuit elastic piece 131 in the direction away from the central axis of the installation cavity 111, and the two second short - circuit portions 1322 are fixed on opposite sides of the connecting portion 1321, so that the two second short - circuit portions 1322 are arranged oppositely and enclose a clamping position with the connecting portion 1321. After the pin short - circuit member 300 is inserted into the clamping position, the two second short - circuit portions 1322 can clamp the pin short - circuit member 300, making the contact between the pin short - circuit member 300 and the second short - circuit elastic piece 132 closer, and further ensuring more stable short - circuit of the contact component 130.

[0061] Furthermore, please refer to Figure 3 , each second short - circuit elastic piece 132 further includes two elastic portions 1323. Each elastic portion 1323 extends downward and bends from the end of the second short - circuit portion 1322 away from the connecting portion 1321, and the two elastic portions 1323 are arranged oppositely; the pin short - circuit member 300 is inserted into the clamping position and is elastically abutted against the two elastic portions 1323.

[0062] In this embodiment, by arranging the elastic portions 1323 at the end of the second short - circuit portion 1322 away from the connecting portion 1321 and using the elastic characteristics of the two elastic portions 1323 to elastically abut against the pin short - circuit member 300, the contact tightness between the second short - circuit elastic piece 132 and the pin short - circuit member 300 is further improved.

[0063] Optionally, the elastic part 1323 is formed by the end of the second short - circuit part 1322 away from the connection part 1321 extending downward and bending. In this way, when the elastic part 1323 contacts the pin short - circuit part 300, the bending direction of the elastic part 1323 during deformation is consistent with the insertion direction of the pin short - circuit part 300, making it easier for the elastic part 1323 to deform and bend, and further making it easier for the elastic part 1323 to elastically abut against the pin short - circuit part 300. The shape of the elastic part 1323 can be set as an arc shape or a V - shape. Of course, the shape of the elastic part 1323 is not limited to the above - mentioned shapes and can also be other shapes, as long as the elastic part 1323 is formed by extending downward and bending.

[0064] In one embodiment, please refer to Figure 3 , each contact component 130 further includes a wire - pressing contact end 133. The end of the second short - circuit elastic piece 132 away from the first short - circuit elastic piece 131 is connected to the wire - pressing contact end 133; the plug body 110 is further provided with at least two first wire - pressing contact holes 114 communicating with the installation cavity 111. Each first wire - pressing contact hole 114 is located outside the two first short - circuit holes 112 and is correspondingly arranged with the wire - pressing contact end 133; the first wire - pressing contact hole 114 is used for the insertion of a plug - in component to contact and conduct with the wire - pressing contact end 133.

[0065] Specifically, the wire - pressing contact end 133 is a cylindrical structure, and the connection part 1321 of the wire - pressing contact end 133 and the second short - circuit elastic piece 132 is connected; each first wire - pressing contact hole 114 is specifically located on the side of each first short - circuit hole 112 away from the first detection hole 113, that is, outside the two first short - circuit holes 112. By setting the wire - pressing contact end 133 to conduct the inserted plug - in component, the plug - in component can more stably contact and conduct with the contact component 130, making it more convenient for external equipment to be repaired. The plug - in component can be a wire - pressing terminal of an external device's cable, and the wire - pressing terminal is provided with a limiting part that cooperates with the wire - pressing elastic piece to achieve unlocking / locking.

[0066] In one embodiment, please refer to Figure 3 , the plug module 100 further includes a wire - pressing elastic piece 150 and a button 160. One end of the wire - pressing elastic piece 150 is fixedly connected to the wire - pressing contact end 133; the button 160 is movably installed in the installation cavity 111 and abuts against the wire - pressing elastic piece 150; after the button 160 drives the wire - pressing elastic piece 150 to move away from the plug - in component, the plug - in component is disengaged from between the wire - pressing elastic piece 150 and the wire - pressing contact end 133.

[0067] Specifically, one end of the wire - pressing elastic piece 150 is connected to the wire - pressing contact end 133 through a fixing component, and the other end of the wire - pressing elastic piece 150 is obliquely abutted against the inner wall of the wire - pressing contact end 133; the plug body 110 is further provided with an installation hole communicating with the installation cavity 111, and the button 160 is movably installed at the installation hole and extends into the installation cavity 111 to abut against the wire - pressing elastic piece 150.

[0068] After the connector extends into the installation cavity 111 from the first wire-pressing contact hole 114, the connector pushes open the wire-pressing elastic piece 150 until the groove on the outer wall of the connector is clamped with the wire-pressing elastic piece 150, so that the connector is fixed in the first wire-pressing contact hole 114 and is in contact conduction with the wire-pressing contact end.

[0069] When maintenance personnel need to pull out the connector from the first wire-pressing contact hole 114, the user presses the button 160, so that the button 160 can push one end of the wire-pressing elastic piece 150 on the wire-pressing contact end 133 until a gap is formed between the wire-pressing elastic piece 150 and the inner wall of the wire-pressing contact end 133, so that the connector can be taken out from this gap.

[0070] Through the cooperation between the wire-pressing elastic piece 150 and the wire-pressing contact end 133, the connector is stably clamped, and thus it is easier for external equipment to repair the plug module 100. By setting the button 160 and using the button 160 to push the wire-pressing elastic piece 150 to deform, it is convenient to pull out the connector from the wire-pressing contact end 133.

[0071] Optionally, a guiding groove is provided on the inner wall of the wire-pressing contact end 133, and the guiding groove extends along the height direction of the wire-pressing contact end 133. One end of the button 160 is slidably connected in the guiding groove; thus, when the button 160 slides in the wire-pressing contact end 133, it can move stably along the extending direction of the guiding groove without shifting its position.

[0072] In one embodiment, please refer to Figure 2 and Figure 4 , the plug body 110 includes at least one module structure, and this module structure is provided with an installation cavity 111 and at least two first short-circuit holes 112; each module structure is assembled in cooperation with two plug contact members 120 and two contact components 130.

[0073] The module structure in this embodiment is the module with the smallest specification. Specifically, in addition to providing an installation cavity 111 and at least two first short-circuit holes 112, the module structure is further provided with at least two first detection holes 113 and at least two first wire-pressing contact holes 114. The two first short-circuit holes 112 are arranged at intervals at the middle line position of the module structure. The two first detection holes 113 are located between the two first short-circuit holes 112. The two first wire-pressing contact holes 114 are respectively located on one side of the two first short-circuit holes 112 away from the first detection holes 113, and the two first short-circuit holes 112, the two first detection holes 113 and the two first wire-pressing contact holes 114 are all arranged along the same straight line.

[0074] In this embodiment, the plug body 110 is designed as a modular structure, and the modular structure is assembled with two plug contacts 120 and two contact components 130, so that the plug module 100 can add or subtract the modular structure according to requirements, be flexibly taken, and save space. It should be noted that referring to Figure 2 , this modular structure is the grounding module of the plug module, and this grounding module can lead the current to the ground and release it to avoid electric shock accidents. In addition, the socket module 200 can also adjust the size by increasing or decreasing the number of socket pins according to the actual situation.

[0075] The present utility model also proposes a connector. Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 . The connector includes a socket module 200, at least one plug module 100 and at least one pin shorting piece 300. The socket module 200 protrudes with an insulating piece 210 and at least two socket pins 220, and the two socket pins 220 are located on both sides of the insulating piece 210; the plug module 100 is also provided with at least one assembly hole 115 communicating with the installation cavity 111, and the assembly hole 115 is coaxially arranged with the contact positions of the two first shorting elastic pieces 131; the pin shorting piece 300 is used to insert into the socket module 200 and / or the plug module 100 to short-circuit the plug module 100 and / or the socket module 200, and the pin shorting piece has at least two mutually conducting contact ends; when each socket pin 220 is inserted into a plug contact 120, the insulating piece 210 is inserted into the assembly hole 115 to separate the two first shorting elastic pieces 131.

[0076] When each socket pin 220 is inserted into a plug contact 120, the insulating piece 210 is inserted into the assembly hole 115, effectively separating the two first shorting elastic pieces 131 and preventing the occurrence of a short-circuit phenomenon. The plug module 100 and the socket module 200 are disassembled to disconnect the connection between the two. This step facilitates the subsequent maintenance work.

[0077] The plug module 100 is connected to the socket module 200 to form a closed circuit. The socket module 200 cooperates with the plug module 100 to maintain the continuity of the circuit under normal working conditions. The detection instrument is used to detect whether the plug module and / or the socket module is energized. The pin shorting piece 300 is used as a connection tool during the maintenance process to ensure a short circuit of the circuit to protect the personal safety of the user.

[0078] In this embodiment, the connector can achieve the functions of automatic short - circuit and short - circuit release according to requirements. The connector includes a socket module 200 and a plug module 100. After the socket module 200 and the plug module 100 are separated, the short - circuit mechanism works, and the two contact components 130 of the plug module 100 are short - circuited with each other to achieve the short - circuit function and withstand voltage requirements. After the socket module 200 and the plug module 100 are plugged and matched, the socket module 200 contacts the plug module 100 first, and then the two contact components 130 are disconnected, realizing normal power transmission, so as to ensure that the voltage circuit is not short - circuited and the current circuit is not open - circuited.

[0079] In one embodiment, referring to Figure 4 and Figure 5 , the socket module 200 includes a socket body 230 and at least two contact assemblies 240. The socket body 230 is also provided with at least two second short - circuit holes 230a, at least two second detection holes 230b, and two second wire - pressing contact holes 230c. The two second detection holes 230b are symmetrically arranged around the central axis of the socket module 200. The two second short - circuit holes 230a are located outside the two second detection holes 230b. The two second wire - pressing contact holes 230c are respectively located on both sides of the two second short - circuit holes 230a away from the second detection holes 230b. The two contact assemblies 240 are installed in the socket body 230. Each contact assembly 240 includes at least one first short - circuit piece 241 and at least one second short - circuit piece 242. The first short - circuit piece 241 is connected to the second short - circuit piece 242, and the two first short - circuit pieces 241 are symmetrically and spaced apart. The socket pin 220 is installed in the socket body 230 and is connected to the second short - circuit piece 242. The second short - circuit hole 230a is used for a contact end of the pin short - circuit member 300 to be inserted and to be in contact conduction with the second short - circuit piece 242.

[0080] In this embodiment, when the socket module 200 needs to be repaired separately, the maintenance personnel can directly insert the two contact ends of the pin short - circuit member 300 into the two second short - circuit holes 230a respectively and be in contact conduction with the second short - circuit piece 242 of the contact assembly 240, so that the two second short - circuit pieces 242 are short - circuited. In this way, after the socket module 200 and the plug module 100 are disassembled, the maintenance personnel can be in contact conduction with the pin short - circuit member 300 through the second short - circuit piece 242 of the contact assembly 240, preventing accidental electric shock during the maintenance process and improving the safety of the maintenance personnel during the maintenance process.

[0081] The connector of the present utility model adopts a safety maintenance method based on the connector. The steps of the maintenance method based on the connector include:

[0082] Step 1: Insert the probe of the detection instrument into the plug module 100 and / or the socket module 200. The probe of the detection instrument is in contact conduction with at least two first short-circuit elastic pieces 131 of the plug module 100 and / or in contact conduction with at least two first short-circuit pieces 241 of the socket module 200, so as to detect whether the plug module 100 and / or the socket module 200 is / are conducting;

[0083] By separately bringing the probe of the detection instrument into contact conduction with the two first short-circuit elastic pieces 131 of the plug module 100, the present utility model can accurately and efficiently detect the electrical conductivity of the plug module 100, significantly improving the detection efficiency and reliability. Similarly, by separately bringing the probe of the detection instrument into contact conduction with the two first short-circuit pieces 131 of the socket module 200, the electrical conductivity of the socket module 200 can be efficiently detected. Or, the probe of the detection instrument is in contact conduction with the plug module 100 and the socket module 200 that have been plugged together, and thus the electrical conductivity of the entire plug connector can be detected.

[0084] Step 2: Insert the pin short-circuiting member 300 into the first short-circuit hole 112 to be in contact conduction with the second short-circuit elastic piece 132, so as to short-circuit at least two second short-circuit elastic pieces 132; and / or insert the pin short-circuiting member 300 into the second short-circuit hole 230a to be in contact conduction with the second short-circuit piece 242, so as to short-circuit at least two second short-circuit pieces 242;

[0085] After the detection instrument outputs the detection result, that is, after the detection instrument confirms whether the plug module 100 is conducting, this operation allows the maintenance personnel to have a preliminary understanding of the electrical conductivity of the plug module 100, facilitating the next operation.

[0086] When the plug module 100 and the socket module 200 are plugged together, and the detection instrument is inserted into the plug module 100 or the socket module 200 and there is conduction, this indicates that the conduction between the plug module 100 and the socket module 200 is normal.

[0087] When the plug module 100 and the socket module 200 are separated, and the detection instrument is inserted into the plug module 100 and conduction is detected, then the conduction between the plug module 100 and the socket module 200 is normal. This is an abnormal working state with an electric shock risk. At this time, the operator can insert the pin short-circuiting member into the plug module 100 and / or the socket module 200 before proceeding with the operation; when the plug module 100 and the socket module 200 are separated, and the detection instrument is inserted into the plug module 100 and no conduction is detected, then the plug module 100 and the socket module 200 are not conducting. This is a normal working state, and the pin short-circuiting member can be further inserted into the plug module 100 and / or the socket module 200 to prevent accidental connection and conduction of electricity between the plug module 100 and the socket module 200 due to misoperation, causing accidental injury to the operator.

[0088] The pin short - circuiting component 300 may include a longitudinal pin short - circuiting component 300a and a transverse pin short - circuiting component 300b. The longitudinal pin short - circuiting component 300a may have only two contact ends. At the plug - module end, the two contact ends of a longitudinal pin short - circuiting component 300a may be respectively inserted into the first short - circuit holes 11 in the same receiving cavity 111 of the plug module 100 to contact and conduct with two second short - circuit elastic pieces, so that the corresponding two contact components 130 are short - circuited. It should be noted that the minimum module of the plug short - circuiting component may at least include a receiving cavity 111, two contact components 130, and two first short - circuit holes 112.

[0089] The transverse pin short - circuiting component 300b may have at least two contact ends. At the plug - module end, at least two contact ends of a transverse pin short - circuiting component 300b may be respectively inserted into the first short - circuit holes 112 in at least two adjacent receiving cavities 111 of the plug module 100 to contact and conduct with at least two second short - circuit elastic pieces, so that the corresponding at least two contact components 130 are short - circuited.

[0090] In the above - mentioned embodiments of the present disclosure, maintenance personnel can insert the longitudinal pin short - circuiting component 300a into the first short - circuit hole 112 in a certain module structure of the plug module 100 to contact and conduct with the corresponding second short - circuit elastic piece 132, so as to achieve local - range maintenance; insert the longitudinal pin short - circuiting component 300a into the second short - circuit hole 230a in the socket module 200 to contact and conduct with the corresponding second short - circuit piece 242, so as to achieve local - range maintenance of the socket module 200.

[0091] Maintenance personnel can insert the contact ends of at least one transverse pin short - circuiting component 300b into the first short - circuit holes 112 in at least two minimum modules of the plug module 100 to contact and conduct with the corresponding second short - circuit elastic pieces 132 one by one for large - range maintenance; insert the contact ends of at least one transverse pin short - circuiting component 300b into the second short - circuit holes 230a in the socket module 200 to contact and conduct with the corresponding second short - circuit pieces 242 one by one, so as to achieve large - range maintenance.

[0092] Maintenance personnel can also insert the longitudinal pin short - circuiting component 300a and the transverse pin short - circuiting component 300b into the plug module 100 and / or the socket module 200 simultaneously to achieve a larger - range maintenance. The embodiments of the present disclosure do not limit the combination manner of the longitudinal pin short - circuiting component 300a and the transverse pin short - circuiting component 300b, and the operator can flexibly use them according to the actual scenario. The number and specific types of the pin short - circuiting components 300 required by the operator can be arranged according to the actual maintenance requirements, so as to meet the various maintenance requirements of the maintenance personnel for the plug module 100.

[0093] Using the pin shorting piece 300 to make contact and conduction with the second shorting spring piece 132 and / or with the second shorting piece 242 provides safety protection for the maintenance operation. This method avoids the risk of directly contacting high-voltage components and greatly improves the safety protection of the operators.

[0094] Step Three: Repair the equipment connected to the plug module end and / or the socket module end.

[0095] Based on the detection results of the detection instrument in Step One and Step Two and the connection situation of the plug module 100 and the socket module 200, determine the conduction situation of the plug module 100 and the socket module 200. Insert the pin shorting piece 300 into the first shorting hole 112 to make contact and conduction with the corresponding second shorting spring piece 132, and / or insert the pin shorting piece 300 into the second shorting hole 230a to make contact and conduction with the corresponding second shorting piece 242, and perform corresponding repairs on the equipment at the plug module end or the socket module end, thereby significantly improving the operation safety of the operators during the electrical maintenance process.
