[0056] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0057] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0058] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0059] Example 1

[0060] Reference Figure 1 to Figure 4 , is the first embodiment of the present invention, which provides a wire connection terminal, comprising, a connecting unit, comprising a wire clamping sleeve 101, an elastic clamping piece sleeved on the outer wall of the wire clamping sleeve 101, and a fixing piece arranged on the inner side of the wire clamping sleeve 101; the wire clamping sleeve 101 is hollow inside; the wire clamping sleeve 101 also includes a notch 101a running through its side wall; the inner wall of the elastic clamping piece is in contact with the outer wall of the wire clamping sleeve 101; after the wire clamping sleeve 101 is compressed, its side wall gathers toward its center position.

[0061] It should be noted that when the wire is inserted into the inner side of the wire clamping sleeve 101, the end of the wire contacts the fixing member; the fixing member can fix the position of the elastic clamping member in the contracted state; so that the elastic clamping member contracts to the side of the wire clamping sleeve 101 away from its free end;

[0062] The interior of the wire clamping sleeve 101 is a hollow structure; preferably, the wire clamping sleeve 101 is a truncated cone structure, and the diameter of the free end of the wire clamping sleeve 101 is relatively large, and the thickness of the inner wall of the wire clamping sleeve 101 gradually decreases along the direction from the small diameter to the large diameter;

[0063] Preferably, the notch 101a is a V-shaped structure, and after the inner wall of the clamping sleeve 101 is compressed, the side wall of the clamping sleeve 101 can be close to the center of the circle; the notch 101a can provide a certain space for the deformation of the clamping sleeve 101;

[0064] Preferably, an arc groove is provided on the inner wall of the cable clamping sleeve 101 near the end with a smaller diameter, and the arc grooves are distributed in an array along the center circumference of the cable clamping sleeve 101; when the end of the elastic clamping piece squeezes the end with a larger diameter of the cable clamping sleeve 101, the side wall of the cable clamping sleeve 101 bends along the position of the arc groove and moves closer to the center position; thereby, the inner wall of the cable clamping sleeve 101 can be closely attached to the outer wall of the cable;

[0065] Preferably, the power member of the elastic clamping member can be an elastic metal structure with a certain deformation ability, such as a spring or a metal spring;

[0066] The fixing member can be a trigger member. When the wire contacts the fixing member, the fixing member can release the limit on the elastic clamping member; the elastic clamping member can clamp the end of the wire clamping sleeve at this time; thereby completing the clamping and fixing of the cable end.

[0067] During use, when the staff is performing electrical work, they need to insert the head of the cable into the inner side of the wire clamping sleeve 101. When the end of the cable contacts the fixing part, the fixing part is pressed. After the fixing part is pressed, it can release the fixation of the elastic clamping part; the end of the elastic clamping part moves to the end of the wire clamping sleeve 101 and squeezes the side wall of the wire clamping sleeve 101 inward; so that the inner wall of the wire clamping sleeve 101 is close to the outer wall of the cable insulation layer, so that the wire clamping sleeve 101 and the cable can be fixedly connected; at this time, the wire clamp can be connected to the wire; thereby ensuring that the circuits are in a connected state.

[0070] It should be noted that the axial hole 101b passes through the side wall of the clamping sleeve 101 and extends to the outside thereof; and the axial hole 101b is arranged near the side of the clamping sleeve 101 away from the free end; the support seat 102 is composed of a plate-like structure and a columnar structure, and a cross intersection is opened inside the columnar structure; the columnar structure is a hollow structure, and a cross-shaped groove passes through the side wall of the support seat 102; and the pressing block 103 is adapted to the support seat 102, and the cross section of the pressing block 103 is a convex structure; the pressing block 103 is adapted to the support seat 102, and the cross section of the pressing block 103 is a convex structure; The rod 105 is a bent plate-like structure, and the rotating shaft 105a is adapted to the shaft hole 101b.

The pressure rod 105 can limit the elastic clamping piece, so that the elastic clamping piece is contracted at the bottom of the wire clamping sleeve 101; and the free end of the wire clamping sleeve 101 is in an open state.

[0071] Preferably, the fixing piece can fix the position of the elastic clamping piece, so that when no wire is inserted into the wire clamping sleeve 101, the free end of the wire clamping sleeve 101 can be opened, and the end can be extended to the outside of the wire clamping sleeve 101 by using the pressure rod 105 and the elastic clamping piece can be limited by the pressure rod 105, thereby ensuring that under normal circumstances, the end of the cable can be inserted into the inside of the wire clamping sleeve 101.

[0072] Furthermore, the pressing block 103 includes a second spring 103a arranged at its bottom; the pressing rod 105 includes a rotating shaft 105a arranged at its central position; the rotating shaft 105a is adapted to the shaft hole 101b; the pressing block 103 and the pressing rod 105 are movably connected through the connecting rod 104; the pressing block 103 can drive the pressing rod 105 to flip when moving along the vertical direction.

[0073] It should be noted that one end of the second spring 103a is connected to the bottom of the pressure block 103, and the other end thereof is located on the inner wall of the support seat 102; the rebound force of the second spring 103a can push the pressure block 103 to move toward the free end of the wire clamping sleeve 101; and the rotating shaft 105a is arranged at the center of the pressure rod 105, and the end of the pressure rod 105 close to the pressure block 103 is connected to the pressure block 103 through the connecting rod 104.

[0074] Under normal circumstances, the rebound force of the second spring 103a can push the pressure block 103 to move in the vertical direction. The movement of the pressure block 103 can drive the connecting rods 104 arranged on both sides thereof to move. As the pressure block 103 moves, the connecting rod 104 can drive one end of the pressure rod 105 to move. After the end of the pressure rod 105 is subjected to force, the pressure rod 105 can rotate along the axial direction of the rotating shaft 105a; thereby, the movement of the pressure block 103 in the vertical direction can drive the pressure rod 105 to rotate along the axial direction of the shaft hole 101b.

[0075] Furthermore, the elastic clamp includes a circular ring 106, a first spring 106a arranged on the end surface of the circular ring 106, and an extrusion ring 106b arranged at the other end of the first spring 106a; the extrusion ring 106b is close to the circular ring 106 and compresses the first spring 106a; the free end of the wire clamp 101 is a bell-mouth structure, and the pressure rod 105 is in contact with the end of the extrusion ring 106b.

[0076] It should be noted that the surface of the circular ring 106 is in contact with the bottom of the wire clamping sleeve 101; and the circular ring 106 is sleeved on the outside of the wire clamping sleeve 101, and the circular ring 106 and the extrusion ring 106b are connected by the first spring 106a; and the end of the wire clamping sleeve 101 is a bell-mouth structure, so that the operator can quickly insert the wire into the inner side of the wire clamping sleeve 101; the end of the pressure rod 105 contacts the surface of the extrusion ring 106b; the pressure rod 105 can press the first spring 106a against the bottom side of the wire clamping sleeve 101; the positions of the circular ring 106 and the extrusion ring 106b are both restricted; the rebound force of the first spring 106a makes the circular ring 106 contact the wire clamping sleeve 101; the extrusion ring 106b contacts the end of the pressure rod 105.

[0077] Furthermore, the support seat 102 includes a slide groove 102a opened inside it; the connecting rod 104 includes a guide groove 104a opened inside it; the pressure rod 105 also includes a guide rod 105b arranged at the end of the pressure rod 105; the connecting rod 104 is connected to the pressure block 103; the connecting rod 104 is a "convex" shaped structure, and both sides of the connecting rod 104 pass through the inner side of the slide groove 102a; the connecting rod 104 is slidably connected to the slide groove 102a; the guide groove 104a is adapted to the guide rod 105b.

[0078] It should be noted that the side wall of the support seat 102 is provided with a slide groove 102a parallel to its axis; the structure of the connecting rod 104 is a cross-shaped structure; the connecting rod 104 is movably connected to the pressure block 103, and the two sides of the connecting rod 104 are located inside the slide groove 102a, and the connecting rod 104 is adapted to the slide groove 102a, and the connecting rod 104 is slidably connected to the support seat 102; the connecting rod 104 is provided with a guide groove 104a perpendicular to the direction of the slide groove 102a; the guide groove 104a is adapted to the guide rod 105b; and the guide rod 105b is located The end of the pressure rod 105 is set; the connecting rod 104 can drive one end of the pressure rod 105 to move in the vertical direction during the vertical movement; the rotating shaft 105a can fix the position of the pressure rod 105; thereby, the pressure rod 105 is turned over and rotated along the axis of the shaft hole 101b; during the rotation of the pressure rod 105, the guide rod 105b moves along the track inside the guide groove 104a; the setting of the connecting rod 104 can make the pressure block 103 move in the vertical direction and drive the pressure rod 105 to turn over along the axis direction of the shaft hole 101b.

[0079] Furthermore, the end of the pressure rod 105 is sunk into the inner side of the clamping sleeve 101; the extrusion ring 106b moves to the end of the clamping sleeve 101; the side walls of the clamping sleeve 101 are close to each other and the ends thereof are cylindrical.

[0080] It should be noted that after the end of the cable is inserted into the inner side of the wire clamping sleeve 101, the end of the cable squeezes the pressing block 103, so that the second spring 103a is compressed. The pressing block 103 can drive the pressing rod 105 to move during the movement in the vertical direction, and the end of the pressing rod 105 flips toward the direction close to the inner wall of the wire clamping sleeve 101; thereby, the end of the pressing rod 105 is away from the squeezing ring 106b; and then, under the elastic force of the first spring 106a, the squeezing ring 106b moves to the outer wall of the free end of the wire clamping sleeve 101; the inner wall of the squeezing ring 106b clamps the free end of the wire clamping sleeve 101 inwardly, so that the side wall of the cable can be gathered inwardly through the side wall of the wire clamping sleeve 101; thereby, the cable is clamped.

[0081] Preferably, the inner wall of the wire clamping sleeve 101 is provided with barbs 101 c ; the number of the barbs 101 c is multiple groups, and the multiple groups of barbs 101 c are equidistantly distributed along the inner wall of the wire clamping sleeve 101 .

[0082] It should be noted that the inner wall of the wire clamping sleeve 101 can also be provided with multiple groups of barbs 101c, and the tips of the barbs 101c are close to the side away from the free end of the wire clamping sleeve 101; and the barbs 101c are bent at a certain arc, and their ends are inwardly bent at a certain angle; when the cable end is inserted into the wire clamping sleeve 101, the side walls of the cable squeeze the barbs 101c to fit tightly against the side walls of the wire clamping sleeve 101, and will not interfere with the cable entering the wire clamping sleeve 101; on the contrary, when the cable end is pulled outward, the end of the barb 101c will be inserted into the inner side of the insulation layer of the cable end.

[0083] Preferably, an arc-shaped groove is provided at the bottom position near the inside of the wire clamping sleeve 101; the free end of the wire clamping sleeve 101 is squeezed by the squeezing ring 106b, so that the side wall of the wire clamping sleeve 101 gathers inward; in this state, with the arc-shaped groove as the ground of a larger truncated cone, the wire clamping sleeve 101 forms a cylindrical structure with smaller diameters at both ends and a larger diameter in the middle; the free end of the wire clamping sleeve 101 is a conical structure, so that the barb 101c provided on the inner wall forms an acute angle with the side wall of the cable; the end of the barb 101c is inserted into the side wall of the cable, thereby clamping and fixing the cable end.

[0084] During use, the staff inserts the end of the cable into the inside of the wire clamping sleeve 101 during the operation, and then uses the end of the cable to contact the surface of the pressing block 103. After being compressed, the pressing block 103 can squeeze the second spring 103a; the pressing block 103 drives the connecting rod 104 to move in the process of moving toward the support seat 102, and the movement of the connecting rod 104 drives the pressing rod 105 to rotate along the axial direction of the shaft hole 101b; as the pressing rod 105 flips, the end of the pressing rod 105 moves away from the surface of the squeezing ring 106b, and this state releases the limit on the first spring 106a; then, under the elastic force of the first spring 106a, the squeezing ring 106b is driven to move to the opening position of the free end of the wire clamping sleeve 101; so that the free end of the wire clamping sleeve 101 gathers toward the center position, so that the side wall of the wire clamping sleeve 101 contacts the inner wall of the cable, thereby completing the clamping and fixing of the wire.

[0085] In summary, the present invention can use the elastic clamping piece to gather the free end of the wire clamping sleeve toward the center of the circle during the process of inserting the cable end into the wire clamping sleeve, so that the inner wall of the wire clamping sleeve can be used to close the outer wall of the wire, thereby realizing the connection between the cable and the wire clamping sleeve; it is more labor-saving and convenient during the operation of the staff, and the work efficiency of the staff is improved to a certain extent.

[0093] It should be noted that, under the action of the rebound force of the third spring 202c, the third spring 202c pushes the first sliding rod 202 to move; as the first sliding rod 202 moves, its end is inserted into the inner side of the limiting groove 106b-1; thereby, the vertical movement of the ring 106 can be limited; thereby further ensuring the stability of the cable end clamping by the wire clamping sleeve 101; in the process of the extrusion ring 106b squeezing the end of the wire clamping sleeve 101, the extension part connected to the end of the wire clamping sleeve 101 is away from the end of the third sliding rod 204, so that the end of the third sliding rod 204 is no longer squeezed by the extension part; thereby, it can be ensured that the end of the first sliding rod 202 is inserted into the inner side of the limiting groove 106b-1.

[0094] When in use, under normal conditions, when the free end of the wire clamping sleeve 101 is in an open state, the extension portion connected to the end of the wire clamping sleeve 101 squeezes the end of the third sliding rod 204, and during the movement of the third sliding rod 204 along the horizontal direction, the second sliding rod 203 is driven to move along the vertical direction, and the movement of the second sliding rod 203 pushes the first sliding rod 202 to move; so that the first sliding rod 202 is away from the side wall of the wire clamping sleeve 101; after the first sliding rod 202 is compressed, the third spring 202c is in a compressed state, and the support block 201 is a trapezoidal structure, so as to provide a deformation space for the extension portion of the end of the wire clamping sleeve 101; and it should be noted that the elastic force of the deformation of the end of the wire clamping sleeve 101 is greater than the elastic force of the third spring 202c; so that when the third sliding rod 204 is compressed, the third spring 202c is in a compressed state;

[0095] When the cable end is inserted into the wire clamping sleeve 101, the squeezing ring 106b moves to the free end of the wire clamping sleeve 101; the squeezing ring 106b can be limited by the extension portion arranged on the outer side of the end of the wire clamping sleeve 101; thereby, the wire clamping sleeve 101 gathers toward the center position, so that the extension portion of the wire clamping sleeve 101 no longer squeezes the end of the third sliding rod 204, and then under the rebound force of the third spring 202c, the first sliding rod 202 is pushed to move, so that the end of the first sliding rod 202 is inserted into the inner side of the limiting groove 106b-1; thereby, the movement of the squeezing ring 106b along its axial direction can be limited; thereby, the stability of the cable end clamping and fixing is ensured.

[0096] In summary, the first sliding rod 202 is inserted into the inner side of the limiting groove 106b-1, which can limit the vertical movement of the extrusion ring 106b, thereby ensuring the stability of the cable clamping by the wire clamping sleeve 101, and then the vertical movement can be limited by the horizontal limit, thereby better ensuring that the cable end is clamped and fixed.
