[0039] Embodiment 2

[0040] Reference Figures 1-7 This is the second embodiment of the utility model. The embodiment is based on the previous embodiment.

[0041] Specifically, the base 101 is provided with a slot 101-1. The slot 101-1 is provided with a first clamping plate 103 and a second clamping plate 104.

[0042] The wire is inserted into the slot 101-1, the first clamping plate 103 is fixed in the slot 101-1, and the second clamping plate 104 is slidable in the slot 101-1. The wire is stably fixed in the slot 101-1 by cooperation of the first clamping plate 103 and the second clamping plate 104.

[0043] The first clamping plate 103 is fixed on one side of the electrically conductive column 106, and the end face of the electrically conductive column 106 is located in the base 101, thereby reducing the risk of electric shock. When it is necessary to detect whether the surge protector is installed in place, the electric pen is used to detect the conduction of the corresponding electrically conductive column 106.

[0044] Specifically, the second clamping plate 104 is fixed on one side of the connecting block 202h, and the connecting block 202h is sleeved with the spring 202i.

[0045] The base 101 is provided with a sliding groove 101-2, and the connecting block 202h is slidable in the sliding groove 101-2. The base 101 is provided with a cavity 101-3, and the two ends of the spring 202i are fixed with the inner wall of the cavity 101-3 and the connecting block 202h respectively. The spring 202i exerts a pushing force on the connecting block 202h, so that the second clamping plate 104 can be attached to the inner wall of the slot 101-1 without other external force.

[0046] When the rectangular block 202g moves towards the second clamping plate 104, it will exert a pushing force on the connecting block 202h, so that the spring 202i is compressed, and the second clamping plate 104 is close to the first clamping plate 103, so as to press the wire, and ensure that the wire is stably fixed between the first clamping plate 103 and the second clamping plate 104.

[0047] The cavity 101-3 is provided to prevent the rectangular block 202g protruding from the mounting block 201a from affecting the rotation of the base 101.

[0048] Specifically, the first moving slot 201a-4 is provided in the mounting block 201a, and the locking block 201c is arranged in the first moving slot 201a-4. The base 101 is fixed with the fixed block 201d, and the fixed block 201d is provided with the locking slot 201d-1. The locking block 201c can be engaged with the locking slot 201d-1.

[0049] Through cooperation of the locking block 201c and the locking slot 201d-1, when they are engaged, the position of the fixed block 201d and the mounting block 201a is locked, so as to lock the base 101 and the mounting block 201a.

[0050] Specifically, the locking block 201c is fixed with the clamping plate 201e, and the rectangular slot 201a-5 is provided in the mounting block 201a. The clamping plate 201e is slidable in the rectangular slot 201a-5.

[0051] The cooperation of the clamping plate 201e and the rectangular groove 201a-5 ensures that the locking block 201c cannot move downward outside the first moving groove 201a-4 under the action of gravity, thereby affecting the locking.

[0052] Specifically, the extrusion block 201f is fixed on the rectangular block 202g, and one end of the extrusion block 201f is inclined.

[0053] The top of the extrusion block 201f can be in contact with and extrude the bottom of the locking block 201c. When the rectangular block 202g moves towards the connecting block 202h, the extrusion block 201f will be moved synchronously, at this time, the inclined surface of the extrusion block 201f will be in contact with and extrude the bottom of the locking block 201c, so that the locking block 201c moves upward along the first moving groove 201a-4 and is clamped in the locking groove 201d-1, thereby locking the base 101 and the mounting block 201a.

[0054] In the initial state, the rectangular block 202g has a certain distance from the connecting block 202h. When the rectangular block 202g starts to move, before contacting the connecting block 202h, the rectangular block 202g drives the extrusion block 201f to move, and the extrusion block 201f will first extrude the locking block 201c, so as to ensure that the locking of the wire will be triggered only after the base 101 and the mounting block 201a are locked.

[0055] Embodiment 3

[0056] Referring to Figures 1-7 For the third embodiment of the utility model, the embodiment is based on the previous two embodiments.

[0057] Specifically, the inner wall of the rectangular groove 201a-5 is fixed with a guide column 201g, and the clamping plate 201e is sleeved outside the guide column 201g.

[0058] The clamping plate 201e is provided with a hole corresponding to the guide column 201g, and the guide column 201g is used to ensure the vertical movement of the locking block 201c and avoid the deviation of the position.

[0059] Specifically, the number of the plug-in modules 102 is multiple, and the number of the clamping members 202 is consistent with and one-to-one corresponding to the plug-in modules 102.

[0060] Specifically, the material of the clamping block 201b is rubber.

[0061] The clamping block 201b has a certain deformation capacity, and the size of the clamping block 201b in the initial state is slightly larger than that of the clamping groove 201a-1. By pushing the base 101 towards the mounting block 201a, the clamping block 201b is deformed, and then clamped in the clamping groove 201a-1, so as to complete the preliminary locking of the base 101 and the mounting block 201a.

[0062] Specifically, the main body assembly 100 further comprises a sliding rail 105, which is in sliding connection with the mounting block 201a.

[0063] In use, after the sliding rail 105 is fixed to a designated position, the mounting block 201a is slid onto the sliding rail 105 from the side, the wire is inserted between the first clamping plate 103 and the second clamping plate 104, and the angle of the base 101 is adjusted to facilitate observation of the wire and ensure that the wire is installed in place, and then the base 101 is pushed towards the mounting block 201a, so that the clamping block 201b is deformed and then clamped in the clamping groove 201a-1, thereby completing the preliminary locking of the base 101 and the mounting block 201a.

[0064] Then, the knob 202j is rotated to drive the rotating column 202a to rotate, the rotating column 202a is rotated to drive the worm 202b to rotate, the worm 202b is rotated to drive the worm wheel 202c to rotate, the worm wheel 202c is rotated to drive the rotating sleeve 202d to rotate, the rotating sleeve 202d is rotated to drive the moving column 202e to move, the moving column 202e is moved to drive the rectangular block 202g to move, the rectangular block 202g is moved to drive the extrusion block 201f to move synchronously, at this time, the inclined surface of the extrusion block 201f contacts and extrudes the bottom of the locking block 201c, so that the locking block 201c moves upwards along the first moving groove 201a-4 and is clamped in the locking groove 201d-1, thereby locking the base 101 and the mounting block 201a.

[0065] At the same time, when the rectangular block 202g moves towards the second clamping plate 104, it will contact the connecting block 202h and apply a pushing force to it, so that the spring 202i is compressed and the second clamping plate 104 moves towards the first clamping plate 103, thereby extruding the wire and ensuring that the wire is stably fixed between the first clamping plate 103 and the second clamping plate 104.

[0066] When the wire needs to be removed, the knob 202j is rotated in the opposite direction to drive the rotating column 202a to rotate in the opposite direction, and the rectangular block 202g moves away from the second clamping plate 104, so that the spring 202i pushes the connecting block 202h to move away from the second clamping plate 104, thereby resetting the second clamping plate 104, at this time, the wire can be removed.

[0067] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and all should be covered in the scope of the claims of the present application.
