All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, the present invention provides an intelligent plug-in testing device for an electric power automation device, which includes a cabinet 1 for connecting a plug-in connector to perform a testing operation, an interface switching distance control mechanism 2 connected to the cabinet 1, and an operation adjusting mechanism 3 connected to the interface switching distance control mechanism 2.

Specifically, the interface conversion distance control mechanism 2 is used for adjusting the shape of the interface according to the shape matching of the plug-in connector to implement the action of interface-specific matching of the plug, and is used for adjusting the matched interface position according to the size of the plug in the process of implementing the action of interface-specific matching of the plug to perform the distance control action of the adjacent interface; the action regulating mechanism 3 is used for driving the interface conversion distance control mechanism 2 to implement the action of the interface pertinence matching plug.

The device accessible interface conversion accuse apart from mechanism 2, realize the quick matching of interface and the interval between the adjacent interface and adjust the action, specifically drive interface conversion accuse apart from mechanism 2 activity through action regulation and control mechanism 3, interface conversion accuse apart from mechanism 2 can match according to the shape of plug connector and adjust the interface shape in order to implement the action of interface pertinence matching plug, at the in-process of implementing the action of interface pertinence matching plug simultaneously, interface conversion accuse apart from mechanism 2 still can be according to the size regulation matched interface position of plug in order to carry out adjacent interface interval regulation and control action.

As shown in fig. 1 and 3, the interface switching distance control mechanism 2 includes a connection cover 21 connected to a surface of the cabinet 1, a shifter 22 connected to the connection cover 21, an interface aggregator 23 connected to the shifter 22 for aggregating a plurality of interfaces, and a distance adjuster 24 connected to the interface aggregator 23 for adjusting a height distance between adjacent interfaces.

The action regulating mechanism 3 comprises a shifting column group 31 which is connected with the connecting cover 21 and used for shifting the shifter 22 to drive the interface aggregator 23 to move, and an interface blocking sheet 32 is connected on the shifting column group 31.

In order to realize the quick matching of the interfaces and the distance adjusting action between the adjacent interfaces, in the process of inserting the plug connector into the interfaces, the interface sealing and blocking piece 32 is stirred to release the interface aggregator 23, and the poking device 22 is stirred through the poking column group 31 to drive the interface aggregator 23 to move, so that the plug connector can be fully inserted into the interfaces matched with the plug connector, and meanwhile, the height distance between the adjacent interfaces is adjusted through the distance adjuster 24.

As shown in fig. 1, 2 and 3, the shifter 22 includes a fixing post 221 connected to an inner wall of the connecting cover 21, a plurality of clamping ring grooves 222 are formed in a side wall of the fixing post 221, a reverse rotation blocking fixing plate 223 having a T-shaped longitudinal section and used for driving the interface polymerizer 23 to rotate around the fixing post 221 is sleeved in the clamping ring grooves 222, a plurality of reverse rotation blocking blocks 224 having a right-angled longitudinal section and used for controlling the reverse rotation blocking fixing plate 223 to rotate in one direction are mounted on an inner wall of the clamping ring grooves 222, a rotating block sliding groove 225 is formed in a side wall of the reverse rotation blocking fixing plate 223, a clamping groove 226 used for clamping the reverse rotation blocking block 224 is formed in an inner wall of the rotating block sliding groove 225, and a push-embedding groove 227 clamped by the shifting post group 31 is formed in a surface of the reverse rotation blocking fixing plate 223.

In order to solve the problem of fast matching of the interface, the dial column set 31 is driven to directly insert into the push-fit groove 227, and meanwhile, the dial column set 31 continuously applying force applies a force rotating around the side wall of the fixed column 221 to the ring rotating fixed disk 223 through the push-fit groove 227; when the rotary fixing disc 223 rotates, the rotary fixing disc can directly rotate in the clamping ring groove 222; since the number of the locking ring grooves 222 is plural, the number of the last interfaces that can be inserted at the same time is plural, and at this time, the reverse rotation-preventing block 224 slides along the rotating block sliding groove 225 on the rotating ring-rotating fixed disk 223; when the reverse rotation preventing block 224 does not enter the position locking groove 226, it is pressed, and then once the reverse rotation preventing block 224 enters the position locking groove 226, the reverse rotation preventing block 224 is reset to fix the rotation fixing disc 223, so that the position is not easy to move. Since the vertical section of the reverse rotation preventing block 224 is a right triangle, the rotation preventing fixed disk 223 can move only in one direction, that is, the rotating rotation preventing fixed disk 223 can only bend the reverse rotation preventing block 224, and once the rotation preventing fixed disk 223 rotates reversely, the rotation preventing fixed disk 223 can not move easily due to the reverse rotation preventing block 224.

In this embodiment, the number of the pushing and inserting grooves 227 is equal to the number of the rotating block sliding grooves 225 and the clamping grooves 232 on the rotating fixing disc 223, so that each time the pushing and inserting groove 227 is clamped and pushed by the shifting post set 31, the interface changes to one model, that is, the clamping grooves 232 are exposed in sequence.

As shown in fig. 1, fig. 3 and fig. 4, the interface aggregator 23 includes a polymeric ring disc 231 sleeved outside the ring rotating fixing disc 223, a clamping groove 232 is formed in the polymeric ring disc 231, the distance adjuster 24 is connected in the clamping groove 232, two limiting grooves 233 which are symmetrically arranged and used for limiting the distance adjuster 24 are formed in the inner side wall of the clamping groove 232, a plurality of step strips 234 are installed on the inner side wall of the clamping groove 232, a conductive cover 235 with a vertical cross section in a shape like a Chinese character 'kou' is arranged at the bottom of the clamping groove 232, and a reset guide block 236 connected with the distance adjuster 24 is arranged on the conductive cover 235.

When the ring rotating fixing disc 223 rotates, the polymeric ring disc 231 moves along with the ring rotating fixing disc until the first clamping groove 232 is separated from the opening on the connecting cover 21; when the connecting plug is not required to be inserted, the opening on the connecting cover 21 is blocked by the interface blocking sheet 32; this is repeated until the size and shape of the interface in the snap groove 232 matches the connector, after which the connector needs to be inserted into the interface.

In the embodiment, if the distance does not need to be adjusted, the connectors can be directly inserted and connected; if the distance needs to be adjusted, the distance between adjacent connectors needs to be adjusted first, and finally the connectors are inserted and connected.

In this embodiment, the connection plug and the connector are both members for inserting into the interface, and they may be the same or different.

As shown in fig. 3 and 4, the reset guide block 236 includes two conductive balls that can be driven to slide along the conductive cover 235, and conductive bars 2361 that penetrate through the conductive cover 235 are respectively connected to the conductive balls; two conductive bars 2361 are arranged in a staggered manner and hinged to each other; a return elastic member 2362 is connected between ends of the two conductive bars 2361 close to the conductive cover 235, and the elastic restoring force of the return elastic member 2362 tends to be used for spreading the two conductive bars 2361; the end of the conductive bar 2361 remote from the conductive cap 235 is connected to the distance adjuster 24.

In order to solve the problem of adjusting the distance between adjacent interfaces, the situation that the power supply is poor due to the change of the position of the interface cannot occur when the distance between the interfaces is adjusted, namely, when the phenomenon that the inserted connectors are mutually attached and extruded occurs, the distance between the adjacent connectors needs to be adjusted.

Based on this, in the specific implementation, the distance adjuster 24 is pulled towards the side far away from the clamping groove 232, then the pulled distance adjuster 24 gradually slides out of the clamping groove 232, and meanwhile, the sliding distance adjuster 24 directly drives the end parts of the conductive bars 2361 to rise together; it will be appreciated that the conducting bar 2361 is pivotally connected to the distance adjuster 24, so that the conducting bar 2361 with one end raised gradually reduces the opening of the "X" shape, i.e. the opening at the other end is correspondingly reduced, and the reducing of the opening at the other end slides along the inner wall of the conducting cover 235 and compresses, so that the distance adjuster 24 does not fail to connect the power in any event. It is understood that the return spring 2362 may be a spring or an elastic rubber block for subsequent return.

As shown in fig. 1, 2 and 4, the distance adjuster 24 includes an interface insert 241 connected with an electrically conductive bar 2361, clamping grooves 242 have been seted up at both ends of the limiting groove 233 corresponding to the interface insert 241, a deformation elastic sheet 243 is installed at the inner wall of the clamping grooves 242, a convex strip is arranged on the side surface of the deformation elastic sheet 243 close to the clamping groove 232, the convex strip can be clamped between any two adjacent ladder bars 234, and a pressing platform 244 is installed on the side surface of the deformation elastic sheet 243 far away from the clamping groove 232.

The side surface of the pressing platform 244 far away from the clamping groove 232 is arc-shaped, and the side surface of the pressing platform 244 far away from the clamping groove 232 is provided with an arc-shaped groove 245 along the extension direction of the arc;

the pressing column 246 is arranged in the clamping groove 242, the pressing column 246 can be driven to slide up and down along the clamping groove 242, and when the pressing column 246 slides to contact the pressing table 244, the pressing table 244 can slide along the arc-shaped groove 245 and can be pushed and extruded along the direction close to the clamping groove 232.

The two ends of the interface insert 241 are respectively connected with the pressing table 244, and the interface insert 241 is provided with a distance adjusting groove 247 for avoiding an adjacent interface.

In order to achieve the purpose of adjusting the distance and solve the problem that the interface is pressed into the clamping groove 232 by the connector when the distance is adjusted, when the distance adjusting device is implemented, once the interface insert block 241 moves towards the direction far away from the clamping groove 232, the deformation elastic sheet 243 can be pulled to move together, the deformation elastic sheet 243 can be prepositioned through a plurality of convex strips on the deformation elastic sheet 243 when moving, as shown in fig. 4, so that the phenomenon that the interface insert block 241 resets with the interface when the connector is not inserted is prevented; once the connector is inserted into the interface, the connector directly presses the pressing column 246, and when the pressing column 246 is pressed, the pressing column slides along the arc-shaped groove 245 and pushes the pressing table 244 to move in a direction away from the pressing column 246, and then the movable pressing table 244 drives the deformation elastic sheet 243 to move together and enables the deformation elastic sheet 243 to press and clamp the step strip 234, so as to improve the stability of the interface insert 241.

When the raised interface insert 241 is inserted with a plug, the non-raised interface insert 241 can be inserted, and since the sidewall of the interface insert 241 is provided with the distance-adjusting groove 247 in the "u" -shaped structure, the distance-adjusting groove 247 on the raised interface insert 241 can play a role of avoiding the joint when the plug is inserted, so as to prevent the extrusion phenomenon between adjacent joints.

In this embodiment, the interface insert 241 that is pulled up should be pulled up intermittently, i.e., every other interface, when the spacing between adjacent interfaces is specifically adjusted.

In this embodiment, the interface insert 241 is used for mounting an interface, and the power of the interface insert is guided by the fixing post 221, that is, the interface insert passes through the rotation fixing plate 223, the conductive cover 235 and the interface in sequence through the fixing post 221.

As shown in fig. 3, the toggle column set 31 includes a plurality of toggle columns 311 corresponding to the position of the polymer ring plate 231 and disposed on the surface of the connecting cover 21, a column groove 312 for limiting the toggle columns 311 is disposed on the surface of the connecting cover 21, a toggle column 313 is mounted on one end of the toggle column 311 close to the column groove 312, the toggle column 313 is in a "V" shape, a push-up spring 314 whose end surface is connected with the inner wall of the bottom of the column groove 312 is sleeved on one end of the toggle column 313, and the other end of the toggle column 313 penetrates through the column groove 312 and extends into the connecting cover 21 to clamp the push-fit groove 227.

In order to solve the problem of adjusting the shape and size of the interface for matching with the connector, when the connector is implemented, only the push-pull column 311 is directly pressed to slide along the cylinder groove 312, and then the pressed push-pull column 311 directly pushes the pull-turn column 313 to move together.

As shown in fig. 3, the turning post 313 is a V-shaped structure, the V-shaped tip of the turning post 313 is connected to the pressing post 311, so that the pressing post 311 can simultaneously apply force to both ends of the turning post 313, then, when the turning post 313 is pressed, one end of the turning post 313 compresses the lifting spring 314, so that the turning post 313 is conveniently reset, the other end of the turning post 313 slides along the inner wall of the pushing and embedding groove 227, and applies a force to the rotating and fixing disc 223 through the pushing and embedding groove 227, the rotating and fixing disc 223 rotates after being stressed, when the rotating and fixing disc 223 rotates to make the pushing and embedding groove 227 separate from the end of the turning post 313, the rotating and fixing disc stops, and then, the pressing and stirring post 311 can be released.

At this time, the pushing spring 314 pushes the rotation column 313 to reset, and then the rotation column 313 is lifted and gradually slides into the next pushing and embedding slot 227, for example, as shown in fig. 3, during which the rotation of the rotation fixing disc 223 cannot be easily driven by the force applied to the rotation fixing disc 223 by the rotation column 313 due to the existence of the reverse rotation block 224.

As shown in fig. 3, the interface blocking piece 32 is disposed on the inner wall of the connecting cover 21, two pushing sliding grooves 321 are disposed on the inner wall of the connecting cover 21, the two pushing sliding grooves are symmetrical about the vertical center line of the poly ring plate 231 and block the interface blocking piece 32 and guide the interface blocking piece 32 to slide, and an anti-separation strip 322 for pushing the dial column 313 to bend is disposed at one end of the interface blocking piece 32 close to the dial column 313.

Promote the inside wall of spout 321 and install a plurality of location platforms 323, and the groove width numerical value that promotes spout 321 is greater than the thickness numerical value of interface separation blade 32, and this location platform 323 is used for carrying out antiskid to anticreep strip 322 spacing, prevents that anticreep strip 322 from breaking away from promoting spout 321.

In order to solve the problem that the dial post 313 is excessively reset when being reset and slides to be separated from the next pushing and embedding groove 227, the dial post 313 needs to be limited, and in the implementation process, once the dial post 313 is pushed by the pushing and lifting spring 314 to reset until the dial post is contacted with the anti-falling strip 322, the dial post 313 is pushed by the anti-falling strip 322 to be bent, so that the phenomenon of excessive reset cannot easily occur.

After the test operation is completed, the connector can be pulled out, and then the interface blocking piece 32 is pulled to slide along one pushing sliding groove 321 with the anti-falling strip 322 until the interface blocking piece 32 slides to be clamped into the other pushing sliding groove 321, so that the interface can be blocked, and dust or other impurities entering the interface are prevented from influencing power supply.

As shown in fig. 3, a return inclined hole 324 is formed at a position corresponding to an extension section of the dial post 313 on an inner side wall of the push chute 321, and a reinforcing post 325 having a V-shaped structure for increasing strength of the dial post 313 is installed in the return inclined hole 324.

The reinforcing column 325 is used for reinforcing the strength of the rotating column 313, so that the resistance part of the reinforcing column 325 is removed by the reinforcing column 325, the rotating column 313 is prevented from being bent due to overlarge resistance in the process of pushing the rotating ring fixing disc 223 to rotate, meanwhile, the inclined hole 324 is corrected to assist in limiting the lifting height of the rotating column 313, the reinforcing column 325 is of a V-shaped structure, and the reinforcing column 325 can be fully bent when being pressed.
