[0021] (1) When the quick docking terminal connector is used to dock the wires, the copper core is inserted into the mounting hole. At this time, the copper core pushes the movable block through the inclined surface of the movable block, so that the movable block drives the protrusion to slide inside the groove. At this time, the first spring is squeezed by the protrusion, and then the protrusion and the movable block always have a tendency to move toward the position of the copper core under the action of the first spring. Then, the movable block can well support the copper core, so that the copper core will not slip, which is convenient for docking;

[0022] Furthermore, the movable blocks are symmetrically distributed about the center of the mounting hole, that is, the movable blocks are distributed on both sides of the copper core, which optimizes the effect of fixing the copper core;

[0023] (2) The quick docking terminal connector, initially, the end of the long pin is located inside the card slot, at which time the extrusion plate will not move, and when the movable block moves to the side, the long pin moves toward the inner slot under the action of the second spring and the limit block, that is, the long pin will always support the inner slot, and when the long pin moves toward the inner slot, the end of the long pin will move out of the card slot, and at this time the connecting rod and the extrusion plate move toward the copper core under the action of the third spring and the side connection block, and then the extrusion plate will support the copper core, so that the copper core has a stable function, thereby optimizing the stability of the copper core;

[0024] Furthermore, the extruded plates are distributed on both sides of the copper core, making the copper core more stable;

[0025] Furthermore, when the wire needs to be removed, the copper core is pulled toward the outside of the mounting hole.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] See also Figure 1-Figure 9 The utility model provides the following technical solution: a quick docking terminal connector:

[0038] Embodiment 1: By setting the movable block 4, the copper core can be supported by the movable block 4 after entering the mounting hole 3, so that the copper core will not slip. Figure 1-Figure 4 As shown:

[0039] It comprises a bottom working block 1, an upper working block 2 is fixedly connected to the upper surface of the bottom working block 1, and mounting holes 3 are provided on the surfaces of the bottom working block 1 and the upper working block 2;

[0040] A quick docking terminal connector, further comprising:

[0041] A movable block 4 is slidably arranged inside the bottom working block 1, and an extrusion plate 5 is slidably arranged inside the bottom working block 1, a long pin 11 is slidably arranged inside the bottom working block 1, and both sides of the long pin 11 are fixedly connected to a limiting block 13, the movable block 4 is symmetrically distributed about the center of the mounting hole 3, and the surface of the movable block 4 is inclined, and both sides of the upper and lower sides of the movable block 4 are fixedly connected to protrusions 6.

[0042] A first spring 7 having an elastic reset function is fixedly connected to the surface of the protrusion 6, and the other side of the first spring 7 is fixedly connected to the inner wall of the bottom working block 1, and a groove 8 corresponding to each of the protrusions 6 is provided inside the bottom working block 1.

[0043] When docking the wires, the copper core is inserted into the mounting hole 3. At this time, the copper core will push the movable block 4 through the inclined surface of the movable block 4, so that the movable block 4 drives the protrusion 6 to slide in the groove 8. At this time, the first spring 7 will be squeezed by the protrusion 6, and then the protrusion 6 and the movable block 4 will always have a tendency to move toward the position of the copper core under the action of the first spring 7. Then, the movable block 4 can hold the copper core well, so that the copper core will not slip, which is convenient for docking. The movable blocks 4 are symmetrically distributed about the center of the mounting hole 3, that is, the movable blocks 4 are distributed on both sides of the copper core, which optimizes the effect of fixing the copper core.

[0044] Embodiment 2: Different from Embodiment 1, the copper core can be extruded twice by the extrusion plate 5, thereby optimizing the stability. Figure 5-Figure 9 As shown:

[0045] An inner groove 12 is formed on the surface of the movable block 4 , and the inner wall of the inner groove 12 is inclined. The end of the long pin 11 fits against the inner wall of the inner groove 12 .

[0046] A limiting groove 14 corresponding to the limiting block 13 is opened inside the bottom working block 1, and a second spring 15 that plays an elastic reset role is fixedly connected to the surface of the limiting block 13, and the other side of the second spring 15 is fixedly connected to the inner wall of the bottom working block 1.

[0047] A connecting rod 9 is fixedly connected to the inner wall of the extrusion plate 5 , and a slot 10 is formed on the surface of the connecting rod 9 . The second spring 15 is initially in a compressed state, and the other side of the long pin 11 is located inside the slot 10 .

[0048] The surface of the connecting rod 9 is fixedly connected with side blocks 16 , and the side blocks 16 are symmetrically distributed about the center of the connecting rod 9 .

[0049] A third spring 17 having an elastic reset function is fixedly connected to the surface of the side connecting block 16 , and the other side of the third spring 17 is fixedly connected to the inner wall of the bottom working block 1 , and the third spring 17 is initially in a compressed state.

[0050] Initially, the end of the long pin 11 is located inside the slot 10, and the extrusion plate 5 will not move at this time. When the movable block 4 moves to the side, the long pin 11 moves toward the inner slot 12 under the action of the second spring 15 and the limit block 13 (and the limit slot 14 limits the moving distance of the limit block 13), that is, the long pin 11 will always support the inner slot 12, and when the long pin 11 moves toward the inner slot 12, the end of the long pin 11 will move out of the slot 10. At this time, the connecting rod 9 and the extrusion plate 5 move toward the copper core under the action of the third spring 17 and the side block 16, and then the extrusion plate 5 will also support the copper core, so that the copper core has a stable function and optimizes the stability of the copper core.

[0051] Embodiment 3: Different from Embodiment 2, the extrusion plate 5 can be quickly pushed back to its original position for easy use later. Figure 8 As shown:

[0052] The surface of the long pin 11 is inclined.

[0053] When it is necessary to remove the wire, pull the copper core toward the outside of the mounting hole 3. After the copper core is pulled out of the mounting hole 3, press the extrusion plate 5 to return the extrusion plate 5 and the connecting rod 9 to their original positions. At this time, the long pin 11 will enter the slot 10 under the action of the second spring 15 and the limit block 13, so as to facilitate the next use.

[0054] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0055] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
