[0025] like Figures 1 to 6 As shown, the press for installing cables in a spring terminal block of the present invention comprises a base 1, a column 2, a spindle box 3, a pressure assembly 4, and a mold 5. Each part and the relationship between them are described in detail below.

[0026] The uprights 2 are fixed to the base 1. The base 1 and uprights are integrally cast, creating a stable structure and providing solid support for the entire press. The base 1 is provided with a T-shaped chute 1a, along which the mold 5 slides and moves. Through holes 1b are provided on both sides of the bottom of the base 1 to allow the base 1 to be secured to the workbench when needed.

[0027] The column 2 includes a column body 2a and a locking screw 2b. A slide rail 2c is provided at one end of the column body 2a. A strip hole 2d is provided on the column body 2a. The locking screw 2b passes through the strip hole 2d and is connected to the spindle box 3, so that the spindle box 3 and the column body 2a are fastened into one.

[0028] After the spindle box 3 is fixed on the column 2, the spindle box 3 is located above the base 1; the spindle box 3 includes a box body 3a, a rotating shaft 3b, a gear 3c, a rack 3d, a spring 3e, and an operating handle 3f. The box body 3a is fixed to the column 2, and the rotating shaft 3b rotates with the box body 3a. A part of the rotating shaft 3b is located inside the box body 3a and is connected to the operating handle 3f, and the other part of the rotating shaft 3b is located outside the box body 3a. The gear 3c is located inside the box body 3a and is fixed on the rotating shaft 3b. The rack 3d passes through the box body 3a, and the rack 3d is meshed with the gear 3c. A step 3g is provided on the circumferential surface of the rack 3d. The spring 3e is sleeved on the rack 3d, and one end of the spring 3e is matched with the inner wall surface of the box body 3a, and the other end of the spring 3e is matched with the step 3g.

[0029] The operating handle 3f consists of a clamping shell, a first locking screw, and a handle body. After the clamping shell clamps the rotating shaft 3b, the first locking screw locks the clamping shell and rotating shaft 3b together, connecting the handle body to the clamping shell. The locking mechanism formed by the clamping shell and the first locking screw facilitates assembly and disassembly and angle adjustment. The operating handle faces outward, ergonomically designed to prevent the operator's hand from colliding with the column 2 during operation, reducing the risk of injury.

[0030] In this embodiment, the locking screw 2b passes through the strip hole 2d and the box body 3a, so that the box body 3a and the column body 2a are fastened together. The box body 3a is provided with a sliding fitting portion 3h, which slides with the slide rail 2c. When adjusting the distance between the box body 3a and the base 1, the locking screw 2b is loosened to allow the box body 3a to slide along the slide rail 2c. When the box body 3a reaches the required position, the box body 3a and the column body 2a are fastened together by the locking screw 2b.

[0031] The pressure assembly 4 is connected to the output end of the spindle box 3 and includes a connecting component 4a and a pressing blade 4b. One end of the connecting component 4a is provided with a concave cavity, into which the rack 3d is inserted and fixed to the connecting component 4a. Preferably, threaded holes are provided on the circumference of the connecting component 4a and the rack 3d. A set screw 4c is threadedly connected to the threaded holes on the circumference of the connecting component 4a and the rack 3d, thereby fastening the connecting component 4a and the rack 3d together. When the rack 3d moves upward along the spindle box 3 and the connecting component 4a forms abutment with the spindle box 3, the connecting component 4a serves as a positioning member for the rack 3d to move upward.

[0032] One end of the pressing knife 4b is connected to the other end of the connecting component 4a. The other end of the pressing knife 4b is flat. When the pressing knife 4b is pressed down, it can match and press into the square groove of the button of the spring terminal block A. The button of the spring terminal block A is pressed down to the limit position, thereby opening the spring leaf of the spring terminal block A to facilitate the insertion of the cable.

[0033] The mold 5 is slidably matched with the base 1 . The mold 5 is provided with a cavity 5 f for matching with the spring terminal block A. The mold 5 is located below the pressure-applying assembly 4 .

[0034] The mold 5 includes a slide 5a, a mold body 5b, and a clamping assembly. The slide 5a slidably engages with the chute 1a. The chute 1a on the base 1 is a T-shaped slot. Therefore, in this embodiment, the slide 5a is composed of a T-shaped seat and a support seat. The T-shaped seat slidably engages with the chute 1a. The support seat is fixed to the T-shaped seat and located above the base 1. The width of the support seat is greater than that of the T-shaped seat. The mold body 5b is clamped against the slide 5a by the clamping assembly. The mold body 5b is also clamped against the support seat in the slide 5a by the clamping assembly. The cavity 5f is provided on the mold body 5b.

[0035] A protrusion 5c is provided on the side wall of the mold body 5b, and the clamping assembly includes an L-shaped pressing block 5d and a clamping screw 5e. One end of the protrusion 5c cooperates with the slide 5a, and the L-shaped pressing block 5d cooperates with the other end of the protrusion 5c. The clamping screw 5e passes through the L-shaped pressing block 5d and is threadedly connected to the slide 5a. In this embodiment, the clamping screw 5e passes through the L-shaped pressing block 5d and is threadedly connected to the support seat in the slide 5a.

[0036] The press in this embodiment further includes a limit assembly that cooperates with the spindle box 3 to limit the feed of the spindle box 3 toward the spring terminal block A. The limit assembly is mounted on the spindle box 3. In this embodiment, the limit assembly is mounted on the rack 3d in the spindle box 3.

[0037] The limiting assembly includes a support plate 6 and a limiting component 7. The support plate 6 is mounted on the rack 3d and is locked with a second locking screw. The support plate 6 is located above the box body 3a. The limiting component 7 is a screw. One end of the limiting component 7 is threadedly connected to the support plate 6, and the other end of the limiting component 7 is a free end for cooperating with the spindle box 3.

[0038] The limiter assembly also includes a guide rod 9, one end of which is fixed to the support plate 6. The spindle housing 3 is provided with a guide hole, with which the guide rod 9 slidably engages. The guide hole is provided in the housing 3a. The housing 3a is also provided with a buffer pad 8. When the limiter assembly descends with the rack 3d, the limiter component 7 abuts against the buffer pad 8, and the rack 3d reaches its maximum downward distance.

[0039] Select the corresponding mold body 5b according to the size of the spring terminal block A. Adjust the height of the spindle box 3 by tightening the screw 2b according to the size of the spring terminal block A. Adjust the limit component 7 to determine the downward dimension of the rack 3d so that during operation, the press knife 4b can just press the button on the terminal block to the limit position, thereby facilitating the easy installation of the cable and allowing the spring sheet to effectively lock the cable.

[0040] Insert spring terminal block A into cavity 5f. Move mold 5. The first button in spring terminal block A corresponds to press blade 4b. Rotate operating handle 3f, which drives shaft 3b to rotate. Shaft 3b drives gear 3c, which drives rack 3d downward. Step 3g on rack 3d compresses spring 3e, and press blade 4b in pressure assembly 4 advances spring terminal block A. Press blade 4b is inserted into the square groove of button B, which is pressed into spring terminal block A. Button B of spring terminal block A is pressed to the limit, thereby opening the spring leaf of spring terminal block A. At this time, the copper wire in the cable is passed through the through hole of spring terminal block A. Release the handle, and the elastic potential energy of spring 3e is released, which drives rack 3d upward. Pressure assembly 4 moves upward with rack 3d, and press blade 4b separates from spring terminal block A. The spring leaf of spring terminal block A returns to its original position, clamping the copper wire in the cable.

[0041] After installing one cable, move the mold 5 so that the second button in the spring terminal block A corresponds to the pressing knife 4b, and repeat the above operation to install the parts of the spring terminal block A where cables need to be installed one by one.

[0042] During operation of the present invention, it is only necessary to make the button B correspond to the pressing knife 4b, and then rotate the operating handle 3f. During the pressing process of the pressing knife 4b, the operator's hand does not need to touch the spring terminal block A, and the pressing knife 4b only acts on the button B, so it will not cause harm to the operator, thereby improving safety performance.
