Description

Technical Field

[0001] This utility model relates to the field of connection line technology, and in particular to a connection line for a distributed I / O module. Background Technology

[0002] Distributed I / O modules are a key component in industrial automation, used for data collection and various control applications.

[0003] Distributed I / O modules are designed for the detection and remote control of various types of standard analog and digital signals (frequency, pulse, or switch status signals) in the field of measurement and control. This series of modules digitizes the measured signal at the front end and transmits it to the host computer via fiber optic cable; or it transmits control commands sent by the host computer to the controlled device for remote control. It is particularly suitable for the status detection and control of equipment in complex electromagnetic environments, such as power supply units, air conditioners, and motors in power or industrial control field switchgear.

[0004] When connecting distributed I / O modules, multiple connecting cables are required. Currently, the connecting cables connected to the distributed I / O modules lack sufficient waterproofing between the cables and the interfaces. In humid conditions, moisture may seep in, affecting usability, and the cables also lack effective stability. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a connection line for a distributed I / O module.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A connection cable for a distributed I / O module includes a connection cable with waterproof sheaths installed at both ends of the connection cable; The waterproof sleeve includes a fixing sleeve, which is fitted onto the outer wall of the connecting wire. A sealing sleeve is fixed to the end face of the fixing sleeve near the connecting wire. Two slots are opened on the outer wall of the fixing sleeve. An L-shaped pressure plate is fixed in the slot by a torsion spring. A clip is fixed to the bottom of the L-shaped pressure plate. Several slots that are adapted to the clip are opened on the outer wall of the connecting wire.

[0007] As a further embodiment of this utility model, two sliders are fixed to the inner wall of the fixing sleeve, and a groove adapted to the sliders is provided on the outer wall of the connecting line.

[0008] As a further embodiment of this invention, the sealing sleeve is made of rubber.

[0009] As a further embodiment of this utility model, a first connecting rod is fixed to the outer wall of the fixing sleeve, and an anti-interference magnetic ring is fixed to the first connecting rod. The anti-interference magnetic ring is sleeved on the outer wall of the connecting line, and the anti-interference magnetic ring plays a certain role in shielding interference.

[0010] As a further embodiment of this utility model, a clamping member is installed on the outer wall of the fixing sleeve. The clamping member includes two second connecting rods, which are fixed to the outer wall of the fixing sleeve and are symmetrically arranged. An extrusion member is installed on the end face of the second connecting rod.

[0011] As a further embodiment of this utility model, the extrusion component includes a mounting block, which is fixed to the second connecting rod. The mounting block has a screw hole, and a bolt is threaded into the screw hole. A pressure plate is fixed to the bottom of the bolt. By rotating the bolt, since the bolt is threadedly connected to the mounting block, the pressure plate on the bolt moves closer to the I / O module. The two pressure plates move closer to each other to clamp and fix the I / O module, effectively stabilizing the connection between the I / O module and the waterproof sleeve.

[0012] The beneficial effects of this utility model are as follows: This utility model employs a connecting wire, a waterproof sleeve, and clips. When connecting the connecting wire, pressing the L-shaped pressure plate connected to the slot via a torsion spring causes the clip on the L-shaped pressure plate to engage with the corresponding slot. The sealing sleeve presses against the connection port of the I / O module, providing waterproofing. By rotating the bolt, which is threaded to the mounting block, the pressure plate on the bolt moves closer to the I / O module. The two pressure plates clamp and fix the I / O module, effectively securing the connection between the I / O module and the waterproof sleeve.

[0013] This utility model features an anti-interference magnetic ring, which provides a certain degree of shielding against interference. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Reference Figure 1-4 A connecting cable for a distributed I / O module includes a connecting cable 1, with waterproof sheaths 2 installed at both ends of the connecting cable 1; The waterproof sleeve 2 includes a fixing sleeve 7, which is fitted onto the outer wall of the connecting line 1. A sealing sleeve 9 is fixed to the end face of the fixing sleeve 7 near the connecting line 1. Two slots 8 are opened on the outer wall of the fixing sleeve 7. An L-shaped pressure plate 10 is fixed in the slot 8 by a torsion spring. A clip head 11 is fixed to the bottom of the L-shaped pressure plate 10. Several clips 5 that are adapted to the clip head 11 are opened on the outer wall of the connecting line 1.

[0019] In this embodiment, two sliders are fixed on the inner wall of the fixing sleeve 7, and a groove 6 adapted to the sliders is opened on the outer wall of the connecting line 1.

[0020] In this embodiment, the sealing sleeve 9 is made of rubber.

[0021] In this embodiment, a first connecting rod 13 is fixed to the outer wall of the fixing sleeve 7, and an anti-interference magnetic ring 12 is fixed to the first connecting rod 13. The anti-interference magnetic ring 12 is sleeved on the outer wall of the connecting line 1, and the anti-interference magnetic ring 12 plays a certain role in shielding interference.

[0022] In this embodiment, a clamping member 4 is installed on the outer wall of the fixing sleeve 7. The clamping member 4 includes two second connecting rods 14. The second connecting rods 14 are fixed on the outer wall of the fixing sleeve 7 and the two second connecting rods 14 are symmetrically arranged. A pressing member is installed on the end face of the second connecting rod 14.

[0023] In this embodiment, the extrusion component includes a mounting block 15, which is fixed to the second connecting rod 14. The mounting block 15 has a screw hole, and a bolt 16 is threaded into the screw hole. A pressure plate 17 is fixed to the bottom of the bolt 16. By rotating the bolt 16, since the bolt 16 is threadedly connected to the mounting block 15, the pressure plate 17 on the bolt 16 moves closer to the I / O module. The two pressure plates 17 move closer to each other to clamp and fix the I / O module, effectively stabilizing the connection between the I / O module and the waterproof sleeve 2.

[0024] Working principle: The system includes a connecting line 1, a waterproof sleeve 2, and a clip 3. The outer wall of the connecting line 1 has a slot 5 and a groove 6. When connecting the connecting line 1, pressing the L-shaped pressure plate 10 connected to the groove 8 via a torsion spring causes the L-shaped pressure plate 10 to deflect. The clip 11 on the L-shaped pressure plate 10 snaps into the corresponding slot 5. When the fixing sleeve 7 moves, the internal slider moves on the groove 6, ensuring that the waterproof sleeve 2 does not rotate relative to the connecting line 1. The sealing sleeve 9 presses against the connection port of the I / O module, providing waterproofing. By rotating the bolt 16, since the bolt 16 is threadedly connected to the mounting block 15, the pressure plate 17 on the bolt 16 moves closer to the I / O module. The two pressure plates 17 move closer to each other to clamp and fix the I / O module, effectively stabilizing the connection between the I / O module and the waterproof sleeve 2.

[0025] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
