[0037] Combination Figures 1 to 6 As shown, the utility model provides an air switch power line quick connection device for power distribution cabinet power-on test, which includes: a sleeve 10, one end of which is provided with a limit portion 110; a test component 20, which is movably inserted into the sleeve 10; one end of the test component 20 is provided with a conductive contact 221, and the conductive contact 221 is arranged on the same side as the limit portion 110; an operating component 30, which is drivingly connected to the test component 20 and is used to drive the test component 20 to move along the length direction of the sleeve 10 to adjust the distance between the limit portion 110 and the conductive contact 221;

[0038] The operating assembly 30 includes a core sleeve clamp 310 and a finger clamp 320, wherein the core sleeve clamp 310 is connected and fixed to the test assembly 20; the finger clamp 320 includes a first finger handle 321 and a second finger handle 322, the first finger handle 321 is rotatably connected to the second finger handle 322, the connecting end 323 of the first finger handle 321 is rotatably connected to the core sleeve clamp 310, and the connecting end 323 of the second finger handle 322 is rotatably connected to the sleeve 10; the first finger handle 321 rotates forward relative to the second finger handle 322 under the action of an external force, so that the core sleeve clamp 310 is separated from the sleeve 10;

[0039] Furthermore, the finger clamp 320 also includes an elastic member 330, and the elastic member 330 is confined between the first finger handle 321 and the second finger handle 322; the first finger handle 321 rotates in the opposite direction relative to the second finger handle 322 under the elastic force of the elastic member 330, so that the core sleeve clamp 310 and the sleeve 10 are arranged close to each other.

[0040] Specifically, in the initial state, the distance between the limit portion 110 and the conductive contact 221 is A, and the distance between the blade convex edge 410 of the air switch 40 and the clamping bolt 420 is C; in order to connect the air switch power cord quick connection device of the present application with the air switch 40 to perform a power-on test, the operator drives the test component 20 to move along the length direction of the sleeve 10 using the operating component 30 to adjust the distance between the limit portion 110 and the conductive contact 221 to B, wherein B<C≤A;

[0041] The operator then places the conductive contact 221 and a portion of the test assembly 20 connected to the conductive contact 221 between the blade flange 410 and the clamping bolt 420 of the air switch 40, and again uses the operating assembly 30 to drive the test assembly 20 to move along the length direction of the sleeve 10 to adjust the distance D between the limit portion 110 and the conductive contact 221.

[0042] At this time, the adjustment of the distance D between the limiting portion 110 and the conductive contact 221 is based on the fact that while the conductive contact 221 is abutting against the clamping bolt 420, the limiting portion 110 can abut against the blade convex edge 410 of the air switch 40, that is, while realizing the access of the test component 20, it can also satisfy the requirement that the air switch power cord quick connection device is clamped and fixed on the air switch 40 to prevent the test component 20 from loosening.

[0043] Specifically, the operator can operate the finger clamp 320 to apply external force thereto, so that the first finger handle 321 rotates positively relative to the second finger handle 322 under the action of the external force. At this time, the core sleeve clamp 310 is separated from the sleeve 10, and during the movement of the core sleeve clamp 310, the test assembly 20 will be driven to move along the length direction of the sleeve 10, shortening the distance between the limit portion 110 and the conductive contact 221.

[0044] When the operator applies an external force in the opposite direction to the finger clamp 320, the first finger handle 321 rotates in the opposite direction relative to the second finger handle 322. At this time, the core sleeve clamp 310 moves closer to the sleeve 10. During the movement of the core sleeve clamp 310, the test assembly 20 is driven to move along the length direction of the sleeve 10, thereby increasing the distance between the limiting portion 110 and the conductive contact 221.

[0045] In this embodiment, an elastic member 330 is added, preferably a spring, and the elastic force of the spring is used to reset the finger clamp 320, thereby increasing the distance between the limiting portion 110 and the conductive contact 221;

[0046] In the initial state, the first finger handle 321 can rotate in the opposite direction relative to the second finger handle 322 under the elastic force of the elastic member 330, so that the core sleeve clamp 310 and the sleeve 10 are arranged close to each other. At this time, the distance between the limit part 110 and the conductive contact 221 is A. The operator can operate the finger clamp 320 to apply external force to it, so that the first finger handle 321 rotates forward relative to the second finger handle 322 under the action of the external force, and compresses the elastic member 330 during the rotation process to store elastic potential energy. At this time, the core sleeve clamp 310 is separated from the sleeve 10, and during the movement of the core sleeve clamp 310, it will drive the test assembly 20 to move along the length direction of the sleeve 10, shortening the distance between the limit part 110 and the conductive contact 221, so that the distance becomes B, where B<A.

[0047] In addition, when the air switch power cord quick connection device is clamped and fixed on the air switch 40, under the elastic force of the elastic member 330, the distance between the limit portion 110 and the conductive contact 221 tends to increase, that is, under the elastic force, the test component 20 can be better fixed on the air switch 40, so that the entire air switch power cord quick connection device is fixed more firmly on the air switch, avoiding sparks due to unstable fixation.

[0048] In other embodiments, the situation where C>A may occur, and the operator can increase the distance between the limiting portion 110 and the conductive contact 221 so that the conductive contact 221 abuts against the clamping bolt 420 while the limiting portion 110 abuts against the blade convex edge 410 of the air switch 40.

[0049] Compared with the prior art, the present application uses the operating component 30 to drive the test component 20 to move according to the distance between the blade convex edge 410 of the air switch 40 and the clamping bolt 420, and adjusts the distance between the limiting portion 110 and the conductive contact 221, so that when the conductive contact 221 abuts against the clamping bolt 420, the limiting portion 110 can abut against the blade convex edge 410 of the air switch 40 to achieve the access of the test power cord 220; in addition, the removal can be achieved by again adjusting the distance between the limiting portion 110 and the conductive contact 221, and the operation is simple and quick.

[0050] In one embodiment, the limiting portion 110 is arranged on the outer peripheral side of the sleeve 10 and extends outward. In the present application, the limiting portion 110 is used to abut against the knife-edge convex edge 410 of the air switch 40 to achieve the limiting fixation of the air switch power cord quick connection device and the air switch 40.

[0051] In one embodiment, a groove 120 is further provided on the outer peripheral side of the sleeve 10, and the groove 120 is extended along the length direction of the sleeve 10; the groove 120 is arranged adjacent to the limiting portion 110 so as to increase the contact area between the limiting portion 110 and the blade convex edge 410 of the air switch 40 to better achieve limiting.

[0052] In one embodiment, the test assembly 20 includes a core sleeve 210 and a test power line 220, wherein the core sleeve 210 is movably inserted into the sleeve 10, and the core sleeve 210 is drivingly connected to the operating assembly 30; the test power line 220 is arranged in the core sleeve 210, and one end of the test power line 220 is electrically connected to the conductive contact 221. In this embodiment, the operating assembly 30 drives the core sleeve 210 to move along the length direction of the sleeve 10, thereby driving the test power line 220 to move synchronously to adjust the distance between the limit portion 110 and the conductive contact 221.

[0053] It should be noted that since the test power cord 220 is a relatively soft wire, it is easy to deform. The present application sets the test power cord 220 in the core sleeve 210, and then movably inserts the core sleeve 210 into the sleeve 10, and utilizes the core sleeve 210 to move in the sleeve 10, thereby ensuring the normal movement of the test power cord 220.

[0054] Furthermore, the test power line 220 is detachably connected to the core sleeve 210 so that another test power line 220 can be replaced after the test power line 220 is damaged.

[0055] Furthermore, the core sleeve clamp 310 is provided with a clamp 311, and the clamp 311 is connected and fixed to the test assembly 20. After the test assembly 20 passes through the fixing through hole of the clamp 311, the fastening screw 312 on the clamp 311 is tightened and fixed, so that the core sleeve 210 and the test assembly 20 are connected and fixed.

[0056] Furthermore, the first finger handle 321 and the second finger handle 322 are further provided with an operating end 324, wherein the operating end 324 of the first finger handle 321 and the connecting end 323 of the first finger handle 321 are respectively located at opposite ends of the first finger handle 321; the operating end 324 of the second finger handle 322 and the connecting end 323 of the second finger handle 322 are respectively located at opposite ends of the second finger handle 322. The middle position of the first finger handle 321 and the second finger handle 322 is the rotation point of the two, and they are connected by a rotating shaft. The operator can press the operating end 324 of the first finger handle and the second finger handle 322 to open the connecting end 323 of the first finger handle 321 and the second finger handle 322, so that the core sleeve clamp 310 is separated from the sleeve 10.

[0057] Furthermore, one end of the elastic member 330 abuts against the operating end 324 of the first finger handle 321, and the other end of the elastic member 330 abuts against the operating end 324 of the second finger handle 322, so as to cooperate with the part where the operator applies external force to better store elastic potential energy.

[0058] Furthermore, the operating end 324 of the first finger handle 321 and / or the second finger handle 322 is provided with an anti-slip stripe 3241 to increase the friction of the operator on the finger clamp 320 .

[0059] The working principle of the air switch 40 power cord quick connection device for power distribution cabinet power-on test of this application is as follows:

[0060] Generally, the distance between the blade convex edge 410 of the air switch 40 and the clamping bolt 420 is C. In the initial state of the air switch power cord quick connection device of the present application, the finger clamp 320 is subjected to the elastic force of the elastic member 330, and the core sleeve clamp 310 moves closer to the sleeve 10, so that the distance between the limiting portion 110 and the conductive contact 221 is A, A≥C.

[0061] In order to achieve the rapid installation of the test power cord 220, the operator can operate the finger clamp 320 to apply external force to it, so that the first finger handle 321 rotates forward relative to the second finger handle 322 under the action of the external force, and compresses the elastic member 330 during the rotation to store elastic potential energy. At this time, the core sleeve clamp 310 is separated from the sleeve 10, and during the movement of the core sleeve clamp 310, the test assembly 20 is driven to move along the length direction of the sleeve 10, shortening the distance between the limit portion 110 and the conductive contact 221, so that the distance becomes B, where B<C≤A.

[0062] The operator can abut the limiting portion 110 against the blade convex edge 410, align the conductive contact 221 with the clamping bolt 420, and then loosen the finger clamp 320. After the external force is lost, the finger clamp 320 causes the conductive contact 221 to move forward and abut against the clamping bolt 420 under the elastic force of the elastic member 330, thereby completing the quick installation, which is simple and quick without the need to loosen and tighten the clamping bolt 420.

[0063] Similarly, when the test power cord 220 needs to be removed, the operator can operate the finger clamp 320 to apply external force thereto, thereby shortening the distance between the limiting portion 110 and the conductive contact 221, thereby easily removing the air switch 40, which is simple and quick without the need to loosen the clamping bolt 420.

[0064] According to the disclosure and teaching of the above description, the technical personnel in the field to which the utility model belongs can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
