A crimping clamp for pre-branched cable production

Abstract

This utility model relates to the technical field of wire and cable production equipment, and discloses a crimping clamp for pre-branched cable production, comprising: two guide rods arranged vertically; two clamping components arranged front and rear, with the upper and lower ends of the clamping components slidably mounted on the two guide rods respectively; a horizontally arranged double-ended screw with opposite thread directions at both ends, and threadedly connected to the two clamping components respectively; and a handwheel mounted on the end of the double-ended screw. This invention solves the problems of current cable core separation methods, which mainly rely on manually inserting wedges between the cores to pry them apart, easily damaging the cable core sheath. Furthermore, the generally large cross-sectional size of pre-branched cables, coupled with the additional twisting force between each core, results in complex operation, high labor intensity, and low work efficiency.

Description

Technical Field

[0001] This utility model relates to the technical field of wire and cable production equipment, specifically to a crimping clamp for pre-branched cable production. Background Technology

[0002] Pre-branched cables are cables prefabricated by manufacturers according to user design drawings during the production of main cables. They are a replacement for busbar power supply in high-rise buildings. They have advantages such as reliable power supply, convenient installation, good waterproof performance, low failure rate, and maintenance-free operation. They are widely used in places with high requirements for power supply safety.

[0003] The production process of pre-branched cables includes multiple steps such as crimping, injection molding, and finishing. Among them, the crimping process is mostly done manually. First, the cable cores need to be separated to maintain sufficient gaps between them, providing operating space for operations such as stripping the insulation layer and crimping the connectors. Currently, the separation of cable cores is mainly accomplished by inserting wedges between the cores to pry them apart, which can easily scratch the cable core sheath. At the same time, since the cross-sectional size of pre-branched cables is generally large, and there is additional twisting force between each core, the above process is complicated, labor-intensive, and inefficient. Utility Model Content

[0004] In view of this, this application provides a crimping clamp for the production of pre-branched cables, which solves the problem that the current separation of cable cores is mainly accomplished by manually driving wedges between the cores to pry them apart, which is easy to scratch the cable core sheath layer. At the same time, since the cross-sectional size of pre-branched cables is generally large, coupled with the additional twisting force between each core, the process is complicated, labor-intensive and inefficient.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A crimping clamp for producing pre-branched cables, comprising:

[0007] Two guide rods 8 are set at the top and bottom;

[0008] Two clamping components are arranged one in front of the other, with the upper and lower ends of the clamping components slidably mounted on two guide rods 8 respectively;

[0009] The horizontally arranged double-ended screw 10 has opposite thread directions at both ends and is threadedly connected to two clamping components respectively.

[0010] Handwheel 11 is installed on the end of double-ended screw 10.

[0011] One type of crimping clamp for pre-branched cable production includes a clamping assembly comprising:

[0012] The vertically arranged side plate 1 has a groove 2 in the middle position to accommodate the cable 12;

[0013] The mold 3 is set inside the groove 2;

[0014] The pressure cap 5 is set on the groove 2, and the upper end of the pressure cap 5 is hinged to the side wall of the side plate 1 through the hinge seat 4, and the lower end is detachably connected to the side plate 1.

[0015] One type of crimping clamp for producing pre-branched cables has a lower end of the pressure cap 5 connected to the side plate 1 by screws 7.

[0016] One type of crimping clamp for producing pre-branched cables has a locking piece 6 between the screw 7 and the side plate 1.

[0017] One type of crimping fixture for producing pre-branched cables has two crimping molds 3, one of which is set on the side wall of the groove 2 and the other is set on the inner wall of the cover 5.

[0018] One type of crimping clamp for producing pre-branched cables has baffles 9 at both ends of the guide rod 8.

[0019] In summary, the present application is described in detail below compared with the prior art:

[0020] This invention achieves the clamping and fixing of cables of different diameters by changing different clamping dies. Rotating the handwheel drives the double-headed screw to rotate, causing the two side plates to come closer together, squeezing and arching the cable core, thus separating the cable core. During the separation process, the cable core does not come into contact with any hard object, effectively protecting the cable core sheath from scratches.

[0021] This method solves the current problem that the separation of cable cores is mainly accomplished by manually inserting wedges between the cores to pry them apart, which easily scratches the cable core sheath. At the same time, because the cross-sectional size of pre-branched cables is generally large, coupled with the additional twisting force between each core, the process is complicated, labor-intensive, and inefficient.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Examples, such as Figures 1 to 2 The following is a crimping clamp for producing pre-branched cables, characterized in that it comprises:

[0028] Two guide rods 8 are set at the top and bottom;

[0029] Two clamping components are arranged one in front of the other, with the upper and lower ends of the clamping components slidably mounted on two guide rods 8 respectively;

[0030] The horizontally arranged double-ended screw 10 has opposite thread directions at both ends and is threadedly connected to two clamping components respectively.

[0031] Handwheel 11 is installed on the end of double-ended screw 10.

[0032] The clamping assembly includes:

[0033] The vertically arranged side plate 1 has a groove 2 in the middle position to accommodate the cable 12;

[0034] The mold 3 is set inside the groove 2;

[0035] The pressure cap 5 is set on the groove 2, and the upper end of the pressure cap 5 is hinged to the side wall of the side plate 1 through the hinge seat 4, and the lower end is detachably connected to the side plate 1.

[0036] The lower end of the pressure cap 5 is connected to the side plate 1 by screws 7.

[0037] A locking piece 6 is provided between the screw 7 and the side plate 1.

[0038] There are two molds 3, one set on the side wall of the groove 2 and the other set on the inner wall of the cover 5.

[0039] Both ends of the guide rod 8 are provided with baffles 9.

[0040] like Figure 3As shown: In use, this utility model first peels off the sheath layer at the main cable joint and removes the branch cable connector. Turning handwheel 11 adjusts the distance between the two side plates 1 to the maximum, opens the pressure cover 5, places the main cable into the pressure mold 3, moves the connector to the center of the two side plates 1, closes the pressure cover 5, and tightens the bolts to press the cables 12 at both ends of the connector. Turning handwheel 11 drives the double-ended screw 10 to rotate, bringing the two side plates 1 closer together and squeezing the cable 12 cores upwards, thus separating the cable 12 cores. Each branch cable connector is then crimped to the main cable core conductor, and insulating tape is wrapped around the exposed conductors. Turning handwheel 11 drives the double-ended screw 10 to rotate, moving the two side plates 1 away from each other, restoring the cable 12 cores to their twisted state. Insulating tape is wrapped around the crimped joint to complete the crimping process, and the process proceeds to the injection molding process.
