Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a plug-in connector. Background Art

[0002] When connecting current or voltage transformers in the power field, it is required that the voltage circuit is not short-circuited and the current circuit is not disconnected. The connector used is required to have a self-shorting function to increase the safety of the system.

[0003] In the related art, the connector includes a male end component, a female end component and a plug-in module, the male end component is provided with at least two male end contacts and a short-circuit spring sheet, each male end contact is connected to a short-circuit spring sheet, the female end component is provided with a female end contact, and the plug-in module is provided with an insulating isolation sheet; the abutment of adjacent short-circuit spring sheets will cause the corresponding two male end contacts to be in a short-circuited state, thereby realizing the short-circuit function and voltage resistance requirements; when the plug-in module is plugged into the female end component and the male end component, the insulating isolation sheet is inserted into the abutment joint of the two short-circuit spring sheets to disconnect the two male end contacts that were originally short-circuited, thereby realizing normal signal or power transmission; when the plug-in module is detached from the female end component and the male end component, the two short-circuit spring sheets of the male end component will abut against each other again to cause the corresponding two male end contacts to be in a short-circuited state.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0032] Please refer to Figures 1 to 6 The utility model provides a plug-in connector 100, comprising: a male end assembly 10, the male end assembly 10 comprising a male end body 11, a male end contact 12 and a movable short-circuit 13, the male end body 11 is provided with an insertion cavity 111 and a first accommodating cavity 112, the male end contact 12 is arranged in the insertion cavity 111, and the movable short-circuit 13 is arranged in the first accommodating cavity 112; a female end assembly 20, the female end assembly 20 comprises a female end body 21 and a female end contact 22, the female end contact 22 is arranged in the female end body 21, and the female end body 21 is provided with a plug-in cavity 111 and a first accommodating cavity 112. The first accommodating cavity 112 is connected to the first insertion hole 211, and a limiting portion 2111 is convexly provided on the hole wall of the first insertion hole 211; and a plug-in module 30, the plug-in module 30 is used to drive the movable short-circuit component 13 to move, and the plug-in module 30 is movably provided with a locking component 31, and the locking component 31 has a locking portion 3121 engaged with the limiting portion 2111; wherein the connector 100 has a plug-in state in which the limiting portion 2111 and the locking portion 3121 are engaged, and a disengaged state in which the limiting portion 2111 and the locking portion 3121 are disengaged.

[0033] Specifically, the plug-in connector 100 can realize the functions of automatic short-circuiting and releasing short-circuiting according to the requirements. The plug-in connector 100 includes a male end component 10, a female end component 20 and a plug-in module 30. The male end component 10 includes a male end body 11, a male end contact 12 and a movable short-circuit 13. The male end contact 12 is arranged in the plug-in cavity 111 of the male end body 11. The male end contact 12 is used to connect the short-circuit spring 14. The first accommodating cavity 112 on the male end body 11 is used to accommodate the movable short-circuit 13 and the short-circuit spring 14. The two adjacent short-circuit springs 14 are connected through the movable short-circuit 13; the female end component 20 includes a female end body 21 and a female end contact 22. The female end contact 22 is arranged in the female end body 21. The female end body 21 is also provided with a first insertion hole 211, and a limit portion 2111 is arranged on the hole wall of the first insertion hole 211. The plug-in module 30 is used to drive the movable short-circuit member 13 to move. The plug-in module 30 includes a movably arranged locking member 31 . The locking member 31 is provided with a snap-fitting portion 3121 . The snap-fitting portion 3121 is used to snap-fit ​​with the limiting portion 2111 .

[0034] The plug-in module 30 is used to be inserted into the first insertion hole 211 and the first accommodating cavity 112 in sequence, that is, to insert the male end component 10 and the female end component 20 in sequence, so that the male end component 10 is in contact and connected with the female end component 20 through the plug-in module 30. After the plug-in module 30 is plugged into the male end component 10 and the female end component 20, the plug-in module 30 abuts against the movable short-circuit component 13, pushing the movable short-circuit component 13 to move, so that the two adjacent short-circuit springs 14 are disconnected, thereby realizing normal signal or power transmission. When the plug-in module 30 is disengaged from the male end assembly 10 and the female end assembly 20, the plug-in connector 100 is in a plug-in state in which the limiting portion 2111 and the snap portion 3121 are engaged. At this time, the limiting portion 2111 and the snap portion 3121 are engaged, so that the pulling out of the plug-in module 30 forms a pause. During the pause, the two adjacent short-circuit spring pieces 14 contact to form a stable contact, thereby achieving the short-circuit function and the voltage resistance requirements. At this time, force is applied to the plug-in module 30 to completely disengage the plug-in module 30 from the male end assembly 10 and the female end assembly 20, and the plug-in connector 100 is in a disengaged state in which the limiting portion 2111 and the snap portion 3121 are disengaged.

[0035] The specific structure of the limiting portion 2111 and the buckle portion 3121 can be set as the cooperation between the protrusion and the slot, or can be set as the cooperation between the elastic buckles. The specific structure can be set according to actual needs, and it is only necessary to form a stop pause for the plug-in module 30 to be pulled out.

[0036] The technical solution of the utility model is to set a snap portion 3121 on the locking piece 31 and set a limiting portion 2111 on the wall of the first insertion hole 211 of the female end component 20; when the plug-in module 30 needs to be pulled out from the male end component 10 and the female end component 20, when it is pulled out to a certain extent, the snap portion 3121 of the plug-in module 30 abuts against the limiting portion 2111 of the female end component 20, and the pulling out of the plug-in module 30 is paused through the card point, ensuring that the short-circuit spring piece 14 in the male end component 10 is in contact and conductive, and the current and voltage are stable, and then the plug-in module 30 continues to be pulled out until it is separated from the male end component 10. This method sets a card point, and when the plug-in module 30 is pulled out, the limit portion 2111 cooperates with the buckle portion 3121 to pause the pulling-out action, and the plug-in module 30 cannot be directly pulled out from the male end component 10. At this time, the short-circuit spring piece 14 in the male end component 10 is in contact and conductive, and the plug-in module 30 is pulled out after the current and voltage are stable, which can ensure that the current contact of the short-circuit spring piece 14 is stable, thereby reducing the risk of electric shock.

[0037] In an embodiment of the utility model, the locking member 31 includes a pressing member 311 and a latching member 312, the pressing member 311 drives the latching member 312 to deform, the latching portion 3121 is arranged on the latching member 312, the latching portion 3121 includes a first latching portion 3121A and a second latching portion 3121B, the limiting portion 2111 includes a first limiting portion 2111A and a second limiting portion 2111B; the first latching portion 3121A is latched with the first limiting portion 2111A, and the second latching portion 3121B is latched with the second limiting portion 2111B.

[0038] It is worth noting that the locking member 31 is configured to include a pressing member 311 and a latch member 312. The pressing member 311 is pressed against the latch member 312 to deform the latch member 312. The latch portion 3121 on the latch member 312 can be disengaged from the limiting portion 2111. The pressing member 311 drives the plug-in module 30 to be disengaged from the male end component 10 and the female end component 20, which can give the operator a signal that it is necessary to wait for the short-circuit spring 14 to stabilize before driving the pressing member 311 to pull out the plug-in module 30.

[0039] The buckle part 3121 is configured as a first buckle part 3121A and a second buckle part 3121B, and the limit part 2111 is configured to include a first limit part 2111A and a second limit part 2111B. The first buckle part 3121A is engaged with the first limit part 2111A, and the second buckle part 3121B is engaged with the second limit part 2111B, that is, two sets of engagement are provided to achieve two functions. Figure 3When the plug-in module 30 is fully inserted into the male end component 10 and the female end component 20, the plug-in module 30 is inserted between the two short-circuit springs 14 of the male end component 10, separating the two short-circuit springs 14, so that the male end component 10 realizes the open circuit function. At this time, the first buckle portion 3121A is not in contact with the first limiting portion 2111A, and the second buckle portion 3121B is engaged with the second limiting portion 2111B. It can be judged that the plug-in module 30 is plugged in place, and the pressing piece 311 is against the end face of the female end component 20 facing the plug-in module 30. The pressing piece 311 cannot be pressed, and the buckle portion 312 will not retract, which will not affect the engagement of the second buckle portion 3121B with the second limiting portion 2111B.

[0040] When the plug-in module 30 is partially pulled out from the male end component 10 and the female end component 20, the plug-in module 30 withdraws from between the two short-circuit springs 14, at this time, the second buckle portion 3121B is disengaged from the second limiting portion 2111B, and the first buckle portion 3121A is engaged with the first limiting portion 2111A, giving a pause signal; the pressing member 311 is held against the buckle portion 312, and pressing the pressing member 311 downward at this time can cause the buckle portion 312 to deform, so that the first buckle portion 3121A retracts and is engaged with the first limiting portion 2111A. 11A is disengaged to prevent the first latch portion 3121A of the latch 312 from scratching the male end component 10. At this time, the plug-in module 30 can be pulled out from the male end component 10 and the female end component 20. This method is easy to operate and convenient for pulling out the plug-in module 30. The first latch portion 3121A is engaged with the first limiting portion 2111A, that is, the plug-in module 30 will pause here when it is partially pulled out, which can give a signal to the staff. After the two short-circuit spring pieces 14 are in contact and stable, the plug-in module 30 can be completely pulled out.

[0041] When the plug-in module 30 is completely separated from the male end assembly 10 and the female end assembly 20 , the locking member 31 is separated from the first accommodating cavity 112 and the first insertion hole 211 , and is disposed away from the limiting portion 2111 .

[0042] In one embodiment, the second snap-fitting portion 3121B is configured as a component with a groove, and the cross-section of the groove is trapezoidal. The second limiting portion 2111B is configured as a convex component, and the cross-section of the second limiting portion 2111B is also trapezoidal. The second limiting portion 2111B cooperates with the second snap-fitting portion 3121B, and the second limiting portion 2111B can extend into the groove of the second snap-fitting portion 3121B for cooperation; by setting a trapezoidal structure to cooperate, when inserting, it can be inserted along the inclined surface for clamping cooperation, and when disassembling, it only needs to be pulled out along the inclined surface, and it can be easily pulled out to complete the disassembly and separation, and the snap-fitting part 312 will not scratch or scrape out hair. This method does not require any other parts to assist, and the clamping or disassembly can be completed by pulling or pushing, which is very convenient to use.

[0043] The cooperation mode of the first limit portion 2111A and the first buckle portion 3121A can also be set as the trapezoidal buckle cooperation mode of the second buckle portion 3121B and the second limit portion 2111B as described above. In another embodiment, the first limit portion 2111A and the first buckle portion 3121A cooperate by respectively setting relative limit surfaces to prevent the plug-in module 30 from continuing to disengage from the outside, giving a signal to the staff, at this time, it is necessary to wait for a while, let the two short-circuit springs 14 contact each other first, and after the current and voltage are stable, the first buckle portion 3121A is driven to disengage from the first limit portion 2111A through the pressing member 311 to completely pull out the plug-in module 30 from the male terminal assembly 10. That is, the connection between the first snap portion 3121A and the first limiting portion 2111A is set to a situation where it needs to be driven by the pressing member 311 to be disengaged, so that the plug-in module 30 cannot be directly disengaged from the male end component 10 and the female end component 20, and can only be disengaged by being driven by the pressing member 311, which facilitates controlling the contact stability of the short-circuit spring 14 and reduces the risk of electric shock.

[0044] In an embodiment of the utility model, the first limiting portion 2111A and the second limiting portion 2111B are sequentially protruded from the hole wall of the first insertion hole 211 from top to bottom; the first buckle portion 3121A and the second buckle portion 3121B are respectively corresponding to the first limiting portion 2111A and the second limiting portion 2111B and are sequentially arranged on the buckle 312.

[0045] Specifically, the arrangement of the first limiting portion 2111A and the second limiting portion 2111B, the first buckle portion 3121A and the second buckle portion 3121B can be selected according to actual needs, and can be arranged at intervals along an oblique direction or along a vertical direction. Figure 5 The first limiting portion 2111A and the second limiting portion 2111B as well as the first buckle portion 3121A and the second buckle portion 3121B are arranged in sequence from top to bottom along the height direction. From top to bottom refers to the direction from the plug-in module 30 to the male end component 10, that is, the plug-in direction of the plug-in module 30 plugged into the male end component 10, so as to facilitate the cooperation of the two sets of card connections. When the plug-in module 30 is plugged into the male end component 10, the second buckle portion 3121B and the second limiting portion 2111B are engaged to lock the plug-in of the plug-in module 30; when the plug-in module 30 is separated from the two short-circuit spring pieces 14, the first buckle portion 3121A is engaged with the first limiting portion 2111A to limit the removal of the plug-in module 30, so that the short-circuit spring pieces 14 are first contacted and stabilized, and then the plug-in module 30 is pulled out.

[0046] In an embodiment of the present invention, the latching member 312 further includes a driving contact portion 3122 , and the pressing member 311 applies force to the driving contact portion 3122 to cause the first latching portion 3121A to disengage from the first limiting portion 2111A and / or the second latching portion 3121B to disengage from the second limiting portion 2111B.

[0047] It is worth noting that the buckle 312 is also provided with a driving contact portion 3122, which can be set as an inclined contact portion or as a middle abutting portion, and the specific structure can be set according to actual needs. Figure 6 In one embodiment, the driving contact portion 3122 is configured as an inclined contact arm, the pressing member 311 abuts against the driving contact portion 3122, and the pressing member 311 presses downward, and through cooperation with the inclined driving contact portion 3122, the buckle portion 3121 of the buckle member 312 is retracted back, so that the first buckle portion 3121A is disengaged from the first limiting portion 2111A, or the second buckle portion 3121B is disengaged from the second limiting portion 2111B. This method has a simple structure, is practical, and is easy to use.

[0048] In an embodiment of the utility model, a limiting step 2112 is provided at the opening of the first insertion hole 211, and the pressing member 311 applies force to a portion of the driving contact portion 3122 and abuts against the limiting step 2112, so that the second buckle portion 3121B is disengaged from the second limiting portion 2111B; the pressing member 311 applies force to the entire driving contact portion 3122 and is away from the limiting step 2112, so that the first buckle portion 3121A is disengaged from the first limiting portion 2111A.

[0049] like Figure 3 and Figure 4 A limiting step 2112 is provided at the opening of the first insertion hole 211. When the plug-in module 30 is fully inserted into the male end assembly 10 and the female end assembly 20, the second buckle portion 3121B is engaged with the second limiting portion 2111B. At this time, the pressing member 311 is spaced a certain distance from the limiting step 2112. When the pressing member 311 applies force to the partial driving contact portion 3122 and abuts against the limiting step 2112, the buckle portion 312 can be driven to retract, driving the second buckle portion 3121B to retract and disengage from the second limiting portion 2111B. At this time, the plug-in module 30 can be detached from the male end assembly 10.

[0050] When the plug-in module 30 is partially pulled out from the male end component 10 and the female end component 20, the first limiting portion 2111A is engaged with the first snap portion 3121A. At this time, the pressing member 311 is away from the limiting step 2112. By applying force to all the driving contact portions 3122 by the pressing member 311, the snap portion 312 can be driven to retract, thereby driving the first snap portion 3121A to retract and disengage from the first limiting portion 2111A. At this time, the plug-in module 30 can be smoothly and completely disengaged from the male end component 10 and the female end component 20.

[0051] That is, the plug-in module 30 is taken out from the male-end component 10 and the female-end component 20 by pressing the pressing piece 311 twice. The structure is simple, the installation is convenient, and two signals can be given, which is highly practical.

[0052] In an embodiment of the utility model, the plug-in module 30 also has an insulating isolation piece 32, and the insulating isolation piece 32 is used to drive the movable short-circuit piece 13 to move. The locking piece 31 is movably arranged on the insulating isolation piece 32, and the insulating isolation piece 32 cooperates with the first insertion hole 211 to realize the plug-in state and the disengaged state.

[0053] In detail, the plug-in module 30 is provided with an insulating spacer 32, which is used to be inserted into the first insertion hole 211 and the first accommodating cavity 112 in sequence. The insulating spacer 32 can push the movable short-circuit 13 to move, so that the two adjacent short-circuit springs 14 are disconnected, and normal signal or power transmission is achieved. The locking member 31 is movably arranged on the insulating spacer 32, and the inner wall of the locking member 31 is spaced from the outer wall of the insulating spacer 32 with a certain distance. The first insertion hole 211 is inserted or pulled out through the insulating spacer 32 to achieve the plug-in state and the disconnected state of the connector 100.

[0054] like Figure 6 In one embodiment, the insulating isolation piece 32 is integrally connected to the plug-in module 30, and the locking piece 31 is in a U-shaped structure. The locking piece 31 is sleeved on the outside of the insulating isolation piece 32. When the insulating isolation piece 32 is inserted into the first accommodating cavity 112, it is convenient to insert the insulating isolation piece 32 into the first accommodating cavity 112 together, and the length of the insulating isolation piece 32 is longer than the length of the locking piece 31, so as to separate the contact between two adjacent short-circuit spring pieces 14.

[0055] In an embodiment of the utility model, the male end assembly 10 also includes a short-circuit spring 14, each of the male end contacts 12 is connected to at least one of the short-circuit springs 14, and the short-circuit springs 14 are arranged in the first accommodating cavity 112, and the two opposite short-circuit springs 14 are in contact and conductive at the center axis position of the first accommodating cavity 112; the insulating isolation member 32 abuts against the movable short-circuit member 13 and drives the movable short-circuit member 13 to move downward so that the two short-circuit springs 14 are disconnected.

[0056] It is worth noting that Figure 5 The short-circuit spring 14 is arranged in the first accommodating cavity 112. Two adjacent short-circuit springs 14 contact each other in the first accommodating cavity 112, so that the two male contact members 12 of the male terminal assembly 10 can realize the short-circuit function. The insulating isolator 32 can be inserted into the male terminal assembly 10. The insulating isolator 32 is inserted into the first accommodating cavity 112. The insulating isolator 32 abuts against the movable short-circuit member 13 and moves the movable short-circuit member 13 downward to separate the two short-circuit springs 14 so that the male terminal assembly 10 can realize the open circuit; the insulating isolator 32 is pulled out from the male terminal assembly 10, so that the short-circuit springs 14 in the male terminal assembly 10 are re-contacted, and the male terminal assembly 10 returns to the short-circuit state. The insulating isolator 32 enables the connector 100 to have a plug-in state for realizing the open circuit function and a disengaged state for realizing the short circuit function.

[0057] In one embodiment, the movable short-circuit 13 may be connected to the first accommodating cavity 112 via an elastic element 15 , and the elastic element 15 enables the movable short-circuit 13 to be reset after being moved so as to be used next time.

[0058] In an embodiment of the utility model, the insulating isolation member 32 is further provided with an abutment portion 321 and two opposite sliding grooves 322, wherein the abutment portion 321 abuts against the movable short-circuit member 13 and drives the movable short-circuit member 13 to move downward, so that the two short-circuit springs 14 are relatively displaced along the sliding grooves 322 and disconnected.

[0059] In detail, in one embodiment, two adjacent short-circuit springs 14 are in contact and connected through the movable short-circuit component 13 in the middle. During the process of inserting the male end component 10 and the female end component 20, the insulating isolation component 32 is abutted against the movable short-circuit component 13 through the abutment portion 321, and drives the movable short-circuit component 13 to move downward, so that the two adjacent short-circuit springs 14 are separated by displacement along the sliding groove 322, which is more convenient to operate.

[0060] In another embodiment, if Figure 5 The short-circuit spring 14 is provided with a first short-circuit portion 141 and a second short-circuit portion 142. The first short-circuit portion 141 is bent to form a relative contact point, and two adjacent second short-circuit portions 142 are in contact through their own elasticity; the second short-circuit portion 142 is formed by punching and bending, and the two adjacent second short-circuit portions 142 are in contact and connected by respectively abutting against the movable short-circuit member 13; by simultaneously providing the first short-circuit portion 141 and the second short-circuit portion 142, a double connection can be achieved, making the self-short-circuit function more reliable. Even if one of the short-circuit springs 14 fails in self-short-circuit after a long period of working, the other self-short-circuit can still work normally, which can ensure the normal self-short-circuit function, ensure the personal safety of the operator, and enhance the safety and reliability of the equipment.

[0061] like Figure 6 The bottom of the insulating isolation piece 32 has an abutment 321, and sliding grooves 322 are provided on the opposite sides of the insulating isolation piece 32, forming a partition in the middle. When the plug-in module 30 is inserted into the male end assembly 10, the two adjacent first short-circuit parts 141 can be separated by the partition of the insulating isolation piece 32, and the two first short-circuit parts 141 move along the two sliding grooves 322 respectively; the insulating isolation piece 32 gradually moves toward the male end assembly 10, and the abutment 321 of the insulating isolation piece 32 will abut on the movable short-circuit part 13, and then push the movable short-circuit part 13 in the direction away from the female end assembly 20, so that the two second short-circuit parts 142 are disconnected from the movable short-circuit part 13, so as to complete the insulating isolation piece 32 to completely separate the two adjacent short-circuit springs 14, so that the connector 100 forms an open circuit state. By providing the insulating isolation piece 32, the insulating isolation piece 32 can squeeze open the two adjacent first short-circuit parts 141 and push open the movable short-circuit part 13 to disconnect the movable short-circuit part 13 from the second short-circuit part 142, so as to simultaneously control the connection or disconnection of the two adjacent first short-circuit parts 141 and the two adjacent second short-circuit parts 142.

[0062] In the embodiment of the present invention, the locking member 31 further includes an elastic member 313 . The elastic member 313 has a compression deformation amount so as to reset the pressing member 311 .

[0063] It is worth noting that an elastic member 313 is also provided. The elastic member 313 can be provided between the locking member 31 and the pressing member 311, or an additional installation groove can be provided to fix the elastic member 313 and connect the elastic member 313 to the pressing member 311. The installation method can be set according to actual conditions, and it is only necessary to enable the elastic member 313 to reset the pressing member 311 after the movement.

[0064] In one embodiment, two ends of the elastic member 313 are respectively in contact with the locking member 31 and the pressing member 311 . The elastic member 313 has a compression deformation. The pressing member 311 can be reset after being pressed by the elastic member 313 to facilitate the next use.

[0065] A first step 34 is protrudingly provided inside the plug-in module 30, and a second step 3111 is protrudingly provided on the outer wall of the pressing piece 311. The second step 3111 cooperates with the first step 34 to limit the pressing piece 311 in the plug-in module 30 to prevent the pressing piece 311 from withdrawing from the plug-in module 30; by cooperating with the elastic piece 313, the pressing piece 311 can be reset and the first step 34 can achieve a stopping effect.

[0066] In an embodiment of the utility model, the plug-in module 30 is provided with a plug-in contact 33, and the female end component 20 is provided with a second insertion hole 212 for inserting the plug-in contact 33, and the female end contact 22 is arranged in the second insertion hole 212, and the male end contact 12 is inserted into the second insertion hole 212 through the plug-in contact 33 to be electrically connected with the female end contact 22; and in the plugged state, the male end contact 12 is in contact and conductive with the female end contact 22, and in the disengaged state, the male end contact 12 is disconnected from the female end contact 22.

[0067] Specifically, the plug-in module 30 is provided with a plug-in contact 33, which is used to be inserted into the second insertion hole 212 and the plug-in cavity 111 in sequence. The female contact 22 is arranged in the second insertion hole 212, and the male contact 12 is arranged in the plug-in cavity 111. Therefore, the plug-in contact 33 is inserted into the male contact 12 and the female contact 22 in sequence, so that the male contact 12 is electrically connected to the female contact 22 through the plug-in contact 33; when the plug-in contact 33 is pulled out from the male contact 12 and the female contact 22, the male end component 10 is disconnected from the female end component 20.

[0068] In detail, in the plugged state, the plug contact 33 can be partially inserted into the plug-in cavity 111. At this time, the insulating isolation piece 32 has not yet contacted the short-circuit spring piece 14, and the short-circuit spring piece 14 is in a contact and conductive state. The two male end contacts 12 are conductive, and the male end component 10 is conductive with the female end component 20; when the plug contact 33 is fully inserted into the plug-in cavity 111, the plug contact 33 is inserted into the male end contact 12 and the female end contact 22, and the male end component 10 is conductive with the female end component 20. At the same time, when the insulating isolation piece 32 is fully inserted into the first accommodating cavity 112, the insulating isolation piece 32 isolates the two short-circuit spring pieces 14, and the short circuit between the two male end contacts 12 is disconnected.

[0069] In the disengaged state, the plug-in contact 33 disengages from the plug-in cavity 111, and the male end assembly 10 is disconnected from the female end assembly 20. At this time, the insulating isolation piece 32 also disengages from the first accommodating cavity 112, so that the two short-circuit springs 14 can contact and conduct, so that the corresponding two male end contacts 12 are short-circuited.

[0070] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
