Description

Technical Field

[0001] The utility model relates to the technical field of PLC controller connectors, in particular to a terminal connector for a cylinder PLC controller. Background Art

[0002] Terminal connectors consist of two or more metal terminals that can be connected to wires or cables through crimping, threading, welding, and other methods to provide a reliable electrical connection and secure the wires. They are primarily used in electronic equipment, household appliances, automotive electronics, and other fields to ensure stable transmission of current and signals. Terminal connectors come in a variety of types, and can be categorized into various types, such as plug-type terminals, threaded terminals, and crimp-type terminals, depending on the connection method and application scenario. Furthermore, they can be further categorized into screw-type terminals, spring-type terminals, and pinhole terminals, depending on their structural characteristics. The terminal connector for a cylinder PLC controller connects the plug end of the cylinder signal line to a terminal connector connected to the cylinder PLC controller to achieve signal transmission.

[0003] The existing cylinder PLC controller terminal connector terminal is directly fixed by screws, which has poor stability and is easy to shake. When the PLC controller signal line is welded to the wiring welding point, the tensile strength of the welding joint cannot be improved, and the welding joint is easy to deform and fall off. Utility Model Content

[0004] In response to the problems in the existing technology, the utility model provides a terminal connector for a cylinder PLC controller. The terminal connector for a cylinder PLC controller avoids the traditional terminal being directly fixed by screws, which has poor stability and is easy to shake. When the PLC controller signal line is welded to the wiring welding point, the tensile strength of the welding head is effectively improved, and the welding head is not easy to deform or fall off.

[0005] The technical solution adopted by the utility model to solve the technical problem is a terminal connector for a cylinder PLC controller, comprising an L-shaped base plate, a wiring terminal, a limit sleeve and a plug connector, wherein the limit sleeve is welded to one side of the top of the L-shaped base plate, the wiring terminal is installed on one side of the limit sleeve through a mounting block and a locking bolt, and the plug connector is provided on one side of the wiring terminal and the plug connector passes through the limit sleeve;

[0006] An L-shaped metal lead is arranged at an equal distance on the other side of the connection terminal, and one end of the L-shaped metal lead is welded with a connection welding point. An arc groove is arranged on the top of the connection welding point, and a metal column is welded in the arc groove.

[0007] By adopting the above technical solution, the terminal connector for the cylinder PLC controller avoids the traditional terminal blocks being directly fixed by screws, which have poor stability and are easy to shake. When the PLC controller signal line is welded to the wiring solder joint, the tensile strength of the welding joint is effectively improved, and the welding joint is not easy to deform or fall off.

[0008] Specifically, a U-shaped support plate is welded on the top of the L-shaped base plate and located on one side of the connection welding point, and wire pressing bolts are installed at equal distances on the top of the U-shaped support plate through screw holes.

[0009] By adopting the above technical solution, the wire pressing bolt is screwed downward to drive the inner triangular wire pressing block to move downward, so as to press and fix the output signal line of the cylinder PLC controller.

[0010] Specifically, the bottom of the wire pressing bolt is connected to an inner triangular wire pressing block via a plastic bearing, and the inner triangular wire pressing block is specifically made of silicone rubber material.

[0011] Specifically, plug holes are embedded at equal distances on one side of the plug connector.

[0012] Specifically, positioning holes are provided at the corners of the ends of the L-shaped substrate.

[0013] By adopting the above technical solution, the positioning holes and matching bolts on the L-shaped base plate are used to facilitate the installation of the entire device into the cylinder PLC controller.

[0014] Beneficial effects of the utility model:

[0015] (1) The terminal connector for a cylinder PLC controller described in the present invention utilizes positioning holes and matching bolts on an L-shaped substrate to facilitate installation of the entire device into the cylinder PLC controller. The L-shaped substrate increases the contact area with the inner wall of the PLC controller, avoiding the traditional wiring terminals being directly fixed by screws, which have poor stability and are prone to shaking. The metal cores of the output signal lines of the cylinder PLC controller are respectively wound around metal columns, and a lead-tin alloy is melted by an electric soldering iron and dripped onto the wiring points, so that the lead-tin alloy solidifies in the arc groove, allowing for rapid welding, effectively improving the tensile strength, and preventing the welding joints from deforming or falling off.

[0016] (2) The terminal connector for the cylinder PLC controller described in the present invention arranges the output signal lines of the connected PLC controller just below the inner triangular wire pressing block. The wire pressing bolts are turned downward to drive the inner triangular wire pressing block to move downward, so as to tighten and fix the output signal lines of the cylinder PLC controller, thereby preventing them from being entangled with each other and avoiding pulling on the wires to cause the wire ends to become loose.

Figure 1-3 As shown, the terminal connector for a cylinder PLC controller described in the present invention includes an L-shaped base plate 1, a terminal block 2, a limit sleeve 3 and a plug connector 4. The limit sleeve 3 is welded to one side of the top of the L-shaped base plate 1. The terminal block 2 is installed on one side of the limit sleeve 3 through a mounting block 6 and a locking bolt 5.

An arc groove 16 is provided on the top of the connection solder joint 9 , and a metal column 15 is welded inside the arc groove 16 .

[0025] When in use, the cylinder PLC controller uses a terminal connector to avoid the traditional terminal 2 being directly fixed by screws, which has poor stability and is easy to shake. When the PLC controller signal line is welded to the wiring welding point 9, the tensile strength of the welding joint is effectively improved, and the welding joint is not easy to deform or fall off.

[0027] When in use, the wire pressing bolt 11 is screwed downward to drive the inner triangular wire pressing block 14 to move downward, so as to press and fix the output signal line of the cylinder PLC controller.

[0031] When in use, it is convenient to plug the signal line at one end of the cylinder into the corresponding plug hole 12 through the plug head, so as to facilitate signal transmission.

[0032] For example, Figure 1 As shown, the present invention also includes positioning holes 7 at the end corners of the L-shaped substrate 1 .

[0033] When in use, the positioning holes 7 on the L-shaped base plate 1 and the matching bolts are used to facilitate the installation of the entire device into the cylinder PLC controller.

[0034] When the utility model is in use, the positioning holes 7 on the L-shaped base plate 1 and the matching bolts are used to facilitate the installation of the entire device into the cylinder PLC controller. The L-shaped base plate 1 increases the contact area with the inner wall of the PLC controller, avoiding the traditional wiring terminal 2 being fixed directly by screws, which has poor stability and is easy to shake.

[0035] The metal wire cores of the output signal lines of the cylinder PLC controller are respectively wound around the metal pillars 15, and the lead-tin alloy is melted by an electric soldering iron and dripped on the connection points, so that the lead-tin alloy solidifies in the arc groove 16, and the welding is fast, which effectively improves the tensile strength and the welding joint is not easy to deform or fall off;

[0036] The PLC controller output signal lines are arranged in the inner triangular wire pressing block 14 below, and the wire pressing bolt 11 is rotated downward to drive the inner triangular wire pressing block 14 to move downward, so as to press and fix the output signal lines of the cylinder PLC controller, achieve the wire arranging effect, prevent mutual entanglement, and avoid pulling the wire body to cause the wire head to be loose.
