Description

Technical Field

[0001] This utility model relates to the field of cable crimping mold technology, and more specifically, to a cable intermediate joint crimping mold. Background Technology

[0002] In cable connection construction, crimping molds are mainly used to reliably connect cable conductors and terminals through mechanical pressure. Crimping terminals at cable joints is a common connection method in electrical engineering. Its core purpose is to ensure the reliability, safety, and durability of electrical connections. When bare wires are directly connected, the contact surface has microscopic unevenness, the actual conductive area is small, and high contact resistance is easily generated. Crimping terminals, on the other hand, use mechanical pressure to plastically deform the wire and terminal metal, forming molecular-level contact, significantly increasing the effective conductive area and reducing resistance.

[0003] In existing technologies, when crimping large-diameter and heavy cable ends to terminals, manual assistance is required to lift the cable so that the cable end and the terminal opening are on the same plane, thus ensuring that the cable end can be smoothly inserted into the terminal. This repetitive manual operation increases the labor intensity and fatigue of workers, and human error is prone to occur, affecting the crimping effect. Utility Model Content

[0004] The purpose of this invention is to provide a cable intermediate joint crimping mold to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a cable intermediate joint crimping mold, comprising a main body, a processing table fixedly connected to the bottom of the main body, an upper mold base fixedly connected to the bottom of the main body and above the surface of the processing table, a lower mold base fixedly connected to the top of the processing table and directly below the upper mold base, a support frame fixedly connected to the side wall of the processing table and to one side of the lower mold base, and an auxiliary support mechanism provided on the top of the support frame, the auxiliary support mechanism being used to support the cable intermediate joint during the crimping process.

[0006] As a further improvement to this technical solution, the auxiliary support mechanism includes side plates symmetrically fixedly connected to the top of the support frame. Support blocks are slidably connected through the interior of each side plate. Two guide rails are symmetrically fixedly connected to the side walls of each side plate. The two support blocks are slidably engaged with the two sets of guide rails. Limiting plates are fixedly connected to the ends of the two sets of guide rails. Elastic elements are fixedly connected to the side walls of the two limiting plates. The end of the elastic element away from the limiting plate is fixedly connected to the side wall of the support block. Several thin round rods are rotatably connected to the ends of the two support blocks away from the elastic elements. The ends of the two support blocks located on the thin round rods are designed with an inclined surface, and the multiple thin round rods maintain the same inclination angle with the inclined end of the support block.

[0007] The cable is clamped by resetting the support block. Because the cable surface is smooth and round, the cable can be pushed towards the lower mold base after being clamped. The support block and the elastic element cooperate to clamp and pre-fix cables of different diameters. At the same time, after the cable is pre-fixed, it ensures that the cable remains stable during insertion into the terminal and crimping.

[0008] As a further improvement to this technical solution, a base is fixedly connected to the top of the support frame and located between the two side plates. Several rotating shafts are evenly rotatably connected to the inner wall of the base. A bottom plate is fixedly connected to the side wall of the support frame, and two conveying components are evenly fixedly connected to the top of the bottom plate.

[0009] By pushing the cable towards the lower mold base with external force, multiple rotating shafts rotate synchronously under the action of friction, thereby completing the cable transport and avoiding additional damage caused by direct contact between the cable surface and the top of the support frame.

[0010] As a further improvement to this technical solution, a limiting block is fixedly connected to the top of one side of the middle of the lower mold base. The limiting block does not interfere with the movement of the upper mold base when it falls. The inner wall of the limiting block is provided with a positioning hole, which is rectangular in shape.

[0011] When the extended end of the terminal block is inserted into the positioning hole, the rectangular positioning hole provides secondary fixation for the stable terminal block. By inserting the cable connector end into the stable terminal block, the subsequent crimping effect is improved.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In this cable intermediate joint crimping mold, an auxiliary support mechanism is set up so that the support block is reset under the rebound action of the elastic element, thereby achieving the clamping effect on the cable. Because the cable surface is round and smooth, the cable can be pushed towards the lower mold base after being clamped. The support block and the elastic element cooperate to satisfy the pre-fixation of cables of different diameters. At the same time, when the cable is pre-fixed, it ensures that the cable remains stable during insertion into the terminal and crimping. It also replaces the traditional method of manually lifting the cable, which not only reduces labor intensity and improves operational safety, but also avoids errors caused by manual lifting that lead to crimping deviations.

[0022] Example 1

[0023] Please see Figures 1-4 As shown, this embodiment provides a cable intermediate joint crimping mold, including a device body 1, a processing table 2 fixedly connected to the bottom of the device body 1, an upper mold base 3 fixedly connected to the bottom of the device body 1 and above the surface of the processing table 2, a lower mold base 31 fixedly connected to the top of the processing table 2 and directly below the upper mold base 3, and a support frame 11 fixedly connected to the side wall of the processing table 2 and one side of the lower mold base 31. First, the terminal block is placed stably in the top groove area in the middle of the lower mold base 31. Then, the cable connector end is inserted into the terminal block. By activating the drive component inside the device body 1, the upper mold base 3 is pressed down. After the upper mold base 3 and the lower mold base 31 are assembled, the purpose of connecting the terminal block and the cable connector end is achieved.

[0024] An auxiliary support mechanism 4 is provided on the top of the support frame 11. The auxiliary support mechanism 4 is used to support the cable intermediate joint during the crimping process. The auxiliary support mechanism 4 includes side plates 41 symmetrically fixedly connected to the top of the support frame 11. Support blocks 42 are slidably connected through the interior of each side plate 41. Two guide rails 43 are symmetrically fixedly connected to the side walls of each side plate 41. The two support blocks 42 are slidably engaged with the two sets of guide rails 43 respectively. Limiting plates 44 are fixedly connected to the ends of each set of guide rails 43. Elastic elements 45 are fixedly connected to the side walls of each limiting plate 44. The end of the elastic element 45 away from the limiting plate 44 is fixedly connected to the side wall of the support block 42. Several thin round rods 12 are rotatably connected to the ends of each support block 42 away from the elastic element 45. Before the cable joint end is inserted into the terminal block, the cable is placed between the two side plates 41. Under the action of the cable's own weight... The cable slides down the surface of the thin round rods 12 with their sloping sides, pressing the support block 42 and causing it to slide towards the limiting plate 44. The limiting plate 44 then presses the elastic element 45, which consists of a shell, a spring, and a limiting element. Under the action of the spring, the support block 42 returns to its original position, achieving the clamping effect on the cable. Because the cable surface is smooth and round, the clamped cable can be pushed towards the lower mold base 31. The cooperation between the support block 42 and the elastic element 45 allows for the pre-fixing of cables of different diameters. Once the cable is pre-fixed, it ensures stability during insertion into the terminal block and crimping. This method replaces the traditional manual lifting of the cable, reducing labor intensity, improving operational safety, and avoiding errors caused by manual lifting that could lead to crimping deviations.

[0025] Both support blocks 42 are located at one end of the thin round rod 12 with a bevel design. Multiple thin round rods 12 maintain the same inclination angle with the beveled ends of the support blocks 42. The beveled design of the thin round rods 12 facilitates the cable to slide between the two side plates 41 and makes it easy to remove the cable after crimping. A base 51 is fixedly connected to the top of the support frame 11 and located between the two side plates 41. Several rotating shafts 52 are evenly rotatably connected to the inner wall of the base 51. When the cable is completely located between the two side plates 41, the bottom of the cable will contact the surface of multiple rotating shafts 52. The cable is pushed towards the lower mold base 31 by external force. Under the action of friction, multiple rotating shafts 52 rotate synchronously, thereby completing the cable transport and avoiding the cable surface from directly contacting the top of the support frame 11 and causing additional damage. A base plate 61 is fixedly connected to the side wall of the support frame 11. Two conveying components 62 are evenly fixedly connected to the top of the base plate 61. The base plate 61, in conjunction with the two conveying components 62, expands the support range for the cable transport path and ensures that the cable remains stable during transport.

[0026] A limiting block 71 is fixedly connected to the top of one side of the middle of the lower mold base 31. The limiting block 71 does not interfere with the movement of the upper mold base 3 when it falls. When the cable connector is pushed horizontally towards the lower mold base 31, the limiting block 71 restricts the movement of the cable connector end after it contacts the side wall of the limiting block 71, allowing the cable connector end to be smoothly connected to the terminal block, which is convenient for subsequent crimping. The inner wall of the limiting block 71 has a positioning hole 72. The positioning hole 72 is rectangular. Before the cable connector end is inserted, the terminal block is placed stably in the groove area at the top of the middle of the lower mold base 31, and the extended end of the terminal block is inserted into the positioning hole 72. The rectangular positioning hole 72 plays a secondary role in fixing the stable terminal block. By allowing the cable connector end to be inserted into the stable terminal block, it helps to improve the subsequent crimping effect.
