Description

Technical Field

[0001] The utility model relates to the technical field of programming controllers, in particular to a terminal connector for a programmable controller. Background Technique

[0002] A programmable logic controller, abbreviated as PC or PLC, is a digital operation controller with a microprocessor for automatic control. It can load control instructions into memory at any time for storage and execution. It mainly consists of functional units such as a CPU, instruction and data memory, input / output interface, power supply, digital-to-analog conversion, etc. It uses a programmable memory to execute instructions for performing operations such as storage logic operations, sequential control, timing, counting, and arithmetic operations, and controls various types of mechanical equipment or production processes through digital or analog input (I) and output (O) interfaces.

[0003] When the existing programming controller is connected to the connector, it is often fixed by bolts or directly welded to the main board through wires. When damage occurs and repair is needed, the disassembly and assembly are relatively troublesome. It is not only cumbersome to operate, time-consuming and laborious, but also increases the burden on the staff, which is not conducive to the quick disassembly and assembly of the programming controller and the connector. In view of the above problems, we propose an improvement and upgrade of a terminal connector for a programmable controller. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a terminal connector for a programmable controller to solve the problems raised in the above background technique.

[0005] To solve the above problems, the following technical solutions are provided:

Threaded rods are arranged inside the hinge seats. Threaded knobs and anti-slip pads are respectively arranged at the upper and lower ends of the threaded rods. A plurality of wiring terminals are arranged on the upper end surface of the connector module, and mounting frames are arranged on both sides of the connector module at the wiring terminals. A winding rod is arranged inside the mounting frame. A dust-proof cloth is arranged on the outer wall of the winding rod. One end of the dust-proof cloth is provided with a pressing buckle, and the pressing buckle is clamped on a clamping groove.

[0007] Further, a chute is opened in the middle of the lower end surface of the bottom plate, and a plurality of mounting grooves are respectively opened on both sides of the chute.

[0008] Further, four fixing plates are provided. A notch is formed inside the fixing plate. The hinge seat is arranged on the notch. An insertion rod is arranged above the hinge seat. One end of the insertion rod penetrates through the hinge seat and the extending end is connected to the fixing plate.

[0009] Further, the threaded rod is in threaded connection with the hinge seat. The threaded knob and the anti-slip pad are respectively fixedly connected to both ends of the threaded rod.

[0010] Further, a placement groove is formed inside the mounting bracket. Both ends of the winding rod are movably installed inside the placement groove. The pressing buckle is fixedly connected to the dust-proof cloth.

[0011] Further, the rear side of the clamping groove is fixedly installed on the fixed block, and the fixed block is fixedly connected to the mounting bracket.

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

[0013] 1. Components such as a bottom plate, a sliding groove, a hinge seat, a threaded knob, a threaded rod, an anti-slip pad, and an insertion rod are arranged inside the device of the present utility model. By sliding the sliding groove inside the bottom plate below the connector module onto the programming controller, and then rotating the deer threaded knob to drive the threaded rod to rotate on the hinge seat, the threaded rod drives the anti-slip pad to lift and lower for fixing with the programming controller. At the same time, the hinge seat is fixed on the fixing plate by using the insertion rod, which can quickly disassemble and assemble the connector module and the programming controller, saving time and effort, being beneficial to reducing the burden on the staff, and having a simple structure.
