Description

Technical Field

[0001] The utility model relates to a PLC controller, in particular to a PLC controller convenient for wiring. Background Art

[0002] A PLC controller is a digital operation electronic system designed for industrial environments. Since it usually requires a large number of input and output signals, these signals will be connected to the wiring ports of the PLC controller through cables, resulting in a large amount of wiring work for the PLC controller, messy line distribution and difficulty in sorting out, which is not conducive to the later maintenance and management of the responsible personnel.

[0003] In view of the above defects, the current treatment methods are shown in patents 202221035757.0 or 202222314947.2. By installing a wiring board outside the wiring port, and the wiring board is provided with wire passing holes for threading, the cable can open the wiring board and complete the wiring when connecting, and then close the wiring board after wiring to buckle the cable into the corresponding wire passing holes, so as to realize the fixing and guiding functions of the cable. However, the defect of this fixing method is that if a long-strip-shaped wiring board is used to fix multiple cables at the same time, the cable on other wiring parts will become loose after the wiring board is opened, reducing the fixing effect on the cable. And if the wiring board is split into multiple monomer structures, and each wiring board corresponds to a cable respectively; it will make the operator easily blocked by the wiring boards at adjacent wiring positions during wiring, that is, a single wiring board cannot leave enough space for the operator to complete the wiring operation after being opened, thus increasing the operation difficulty of the operator. In addition, the existing wiring board is mostly fixed by screwing, and this fixing method requires the operator to screw in and out the screws with tools every time, thus increasing the operation difficulty of the operator.

[0004] Therefore, the existing fixing method of the PLC controller for cables has problems of poor fixing effect and inconvenient operation. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a PLC controller convenient for wiring. It can facilitate the operation of the operator while ensuring the fixing effect on the cable.

[0006] Technical solution of the utility model: A PLC controller convenient for wiring, including a controller body, a wiring port is provided on the controller body, and an installation strip is detachably connected to the controller body on one side of the wiring port. A number of fixing components are connected side by side on the installation strip; the fixing component includes a positioning column, one end of the positioning column is detachably connected to the installation strip, the other end of the positioning column is connected with a top cover, an arc-shaped clamp is slidably connected to the positioning column, and a wire passing groove for the cable to pass through is formed between the arc-shaped clamp and the installation strip. An elastic member sleeved outside the positioning column is provided between the arc-shaped clamp and the top cover.

[0007] In the aforementioned PLC controller convenient for wiring, a limiting rod connecting the installation strip is provided on the outer side of the positioning column, and the arc-shaped clamp is slidably connected to the limiting rod through a round hole.

[0008] In the aforementioned PLC controller convenient for wiring, a label for marking the cable is pasted on the surface of the top cover.

[0009] In the aforementioned PLC controller convenient for wiring, both ends of the installation strip are slidably connected to the controller body through guide rails. Long strip holes are provided on the guide rails. The end of the installation strip is connected with a locking bolt, and the end of the locking bolt passes through the guide rail through the long strip hole and fits with the outer wall of the guide rail.

[0010] In the aforementioned PLC controller convenient for wiring, the number of the installation strips is multiple, and multiple installation strips are arranged side by side on the guide rails.

[0011] Compared with the prior art, the utility model has the following characteristics:

[0012] (1) Through the structural cooperation of the arc-shaped clamp and the installation strip, the operator can open the arc-shaped clamp by pulling, and after the cable is buckled into the wire passing groove, the arc-shaped clamp is loosened to clamp the cable under the action of the elastic member, that is, the functions of fixing and guiding the cable are realized, which is convenient for the operator to operate; on this basis, through the limitation of the connection structure of the arc-shaped clamp, the arc-shaped clamps can be densely distributed on the installation strip, that is, on the one hand, the fixation of a single cable is realized, so as to improve the fixation effect of the cable, and on the other hand, the interval distance between adjacent arc-shaped clamps can be reduced, so as to improve its space utilization rate and the clamping quantity of the cable;

[0013] (2) On the basis of the arc-shaped clamp structure, the manufacturer can also adjust the shape of the arc-shaped clamp according to the cable size, and replace the installation strip according to the shape and distribution position of the arc-shaped clamp; thus, the stable clamping of different specifications of cables is realized, and its fixation effect is improved;

[0014] (3) By defining the connection structure between the mounting strip and the controller body, the mounting strip can also adjust the spacing distance between it and the wiring port as needed, that is, while ensuring the cable fixing effect, a space for the operator to wire is left, effectively improving the operation convenience of the operator; on this basis, by arranging multiple mounting strips side by side on the guide rail, it can further improve the cable fixing and guiding effects and ensure the neat arrangement of the cables on the controller body;

[0015] (4) Through the cooperation of the top cover and the label, the arc-shaped clip can also mark the cable after clamping, that is, it is convenient for the operator to manage and identify, reducing the difficulty of later cable maintenance and management;

[0016] Therefore, the utility model can facilitate the operation of the operator while ensuring the cable fixing effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following further illustrates the utility model in conjunction with the drawings and embodiments, but it shall not be used as a basis for limiting the utility model.

[0022] Embodiment. A PLC controller convenient for wiring, the structure is as Figure 1 shown, including a controller body 1, a wiring port 2 is provided on the controller body 1, a mounting strip 3 is detachably connected to the controller body 1 on one side of the wiring port 2, and a plurality of fixing components are connected side by side on the mounting strip 3; the fixing component includes a positioning column 4, one end of the positioning column 4 is threadedly connected to the mounting strip 3, the other end of the positioning column 4 is connected with a top cover 5, an arc-shaped clip 6 is slidably connected to the positioning column 4, a wire groove 7 for the cable to pass through is formed between the arc-shaped clip 6 and the mounting strip 3, and an elastic member 8 sleeved outside the positioning column 4 is arranged between the arc-shaped clip 6 and the top cover 5, and the elastic member 8 can be a spring.

[0023] A limiting rod 9 for connecting and mounting the strip 3 is provided on the outer side of the positioning post 4. The number of the limiting rods 9 is two and they are symmetrically arranged on both sides of the positioning post 4. The arc-shaped clamp 6 is slidably connected to the limiting rod 9 through a round hole.

[0024] A label for marking the cable is pasted on the surface of the top cover 5.

[0025] Both ends of the mounting strip 3 are slidably connected to the controller body 1 through guide rails 10. Long strip holes 11 are provided on the guide rails 10. The end of the mounting strip 3 is connected with a locking bolt 12. The end of the locking bolt 12 passes through the guide rail 10 through the long strip hole 11 and fits against the outer wall of the guide rail 10. After the locking bolt 12 is tightened, the mounting strip 3 is fixed on the guide rail 10.

[0026] The number of the mounting strips 3 is multiple, and the multiple mounting strips 3 are arranged side by side on the guide rail 10.

[0027] The working principle of the utility model: When the utility model is in use, the operator first adjusts the position of the mounting strip 3 on the guide rail 10 according to the wiring position and routing effect of the cable at the wiring port 2. Then, each arc-shaped clamp 6 is connected to the mounting strip 3 through the elastic member 8 and the positioning post 4. After the signal input and signal output cables are connected to the wiring port 2, the operator pulls the arc-shaped clamp 6 outwards, so that the arc-shaped clamp 6 overcomes the elastic force of the elastic member 8 and opens outwards and separates from the mounting strip 3. Then, the cable is buckled into the routing groove 7 from one side of the arc-shaped clamp 6, and then the arc-shaped clamp 6 is released to make it return to the state of fitting with the mounting strip 3 under the elastic return force of the elastic member 8, that is, the fixation of the cable after wiring is realized. After the cable is clamped by the arc-shaped clamp 6, the operator can also paste the label corresponding to the cable on the top cover 5 of the corresponding positioning post 4, so as to facilitate the later management and maintenance of the cable.
