Description

Technical Field

[0001] This utility model relates to the field of cable chain technology, specifically to a small-pitch, easy-to-open heavy-duty cable chain. Background Technology

[0002] Cable chains are chain structures used to protect and guide cables, oil pipes, and air pipes in mobile equipment. They are widely used in automated equipment such as CNC machine tools and robots. They can confine cables inside the chain and accompany the reciprocating motion of the equipment, effectively preventing cable wear, entanglement, and tensile damage.

[0003] In the prior art, the terminal block used to fix the cable ends of the cable chain is usually integrally molded with the main body of the cable chain. Since the number and spacing of the cables are determined during manufacturing, users cannot flexibly adjust or expand them according to the differences in the number and diameter of the cables in actual applications. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the defect that the connection board in the prior art cannot meet the assembly of cables of different quantities and diameters, thereby providing a convenient small-pitch opening heavy-duty cable chain for easy use by users.

[0005] Therefore, this utility model provides a small-pitch, easy-to-open heavy-duty cable chain, including a cable chain body, connectors, and a terminal block. Two connectors are installed at both ends of the cable chain body. Each connector includes two oppositely arranged connector plates and two baffles disposed between the two connector plates. At least one terminal block is detachably installed on the baffles. The terminal block includes an integrally connected wiring portion and a connecting portion. The connecting portion is formed with a slot that is adapted to engage with the baffles.

[0006] The connector has multiple mounting holes on its upper, lower, and front faces.

[0007] A metal cap is provided inside the mounting hole.

[0008] The inner wall of the connector plate is provided with a boss.

[0009] There are multiple wiring portions, and the multiple wiring portions are distributed at intervals along the length direction of the connection portion.

[0010] The drag chain body is formed by splicing multiple chain links. The chain plate of each chain link includes a first chain plate portion and a second chain plate portion arranged on the left and right. The outer side of the first chain plate portion is provided with multiple fan-shaped limiting grooves. The second chain plate portion is provided with multiple limiting blocks that cooperate with the limiting grooves. When two adjacent chain links are spliced, the multiple limiting blocks on the second chain plate portion of one chain link are engaged into the multiple limiting grooves on the first chain plate portion of the other chain link.

[0011] Each of the plurality of limiting grooves has a latching platform on one side that can abut against the limiting block.

[0012] At least one of the fastening platforms is provided with a guide slope.

[0013] The number of the limiting block, the limiting groove, and the fastening platform are all three.

[0014] The technical solution of this utility model has the following advantages: 1. The present invention provides a small-pitch, easy-to-open heavy-duty cable chain with a terminal block that is detachably installed on the baffle. The terminal block includes an integrally connected wiring part and a connecting part. The connecting part is formed with a slot that fits and engages with the baffle. This achieves modularity of the terminal block. Users can flexibly add or remove terminal blocks according to the actual number of wires, which greatly improves the flexibility and convenience of use and reduces material waste.

[0015] 2. The small-pitch, easy-to-open heavy-duty cable chain provided by this utility model significantly enhances the strength and wear resistance of the mounting hole by setting a metal cap. In heavy-duty applications that frequently install screws or bear large tensile forces, it can effectively prevent thread stripping and hole wall wear, thus extending the service life and reliability of the joint.

[0016] 3. The small-pitch opening convenient heavy-duty cable chain provided by this utility model has multiple buckles and multiple limit blocks that abut against each other, further enhancing the load-bearing capacity of the cable chain.

[0017] 4. The small-pitch, easy-to-open heavy-duty cable chain provided by this utility model has a guide slope on the buckle, which reduces the difficulty of manual assembly and improves assembly efficiency. Attached Figure Description
