Description

Technical Field

[0001] The utility model relates to the technical field of safety protection equipment, in particular to a safety touch anti-collision strip. Background Art

[0002] A safety touch edge is a rubber strip-shaped pressure-sensitive switch. The safety edge and the safety buffer are flexible and bendable strips, which can be fixed on the edges of moving parts such as machine tool worktables and electric doors where there are risks of extrusion and shearing.

[0003] When the safety touch edge is subjected to external pressure or impact, such as being contacted or collided by a person or an object, these flexible safety edges will be compressed, and the internal sensor or switch device will immediately sense this change. Once it senses the external pressure or impact, it will quickly generate a signal output, which is usually connected to a control system or a safety device to trigger corresponding safety protection measures. In the application scenario of the safety touch edge, after receiving the signal, the control system or the safety device will immediately execute corresponding actions, such as stopping the movement of the equipment, cutting off the power supply, etc., to ensure the safety of personnel and objects. This working principle enables the safety touch edge to be widely used in fields such as industrial production, automated warehouses, logistics systems, electric doors, and amusement facilities.

[0004] The current safety touch edge structure can detect external pressure or impact, but has low detection sensitivity, is not convenient to connect with external wires, and in addition, the current safety touch edge structure is relatively complex and has a high manufacturing cost.

[0013] As an improved technical solution, the conductive wire includes bulletproof wire, copper foil wire and silver foil wire, and the copper foil wire and the silver foil wire are wound around the bulletproof wire.

[0014] As an improved technical solution, a wiring component is provided at the end of the elastic rubber tube. The wiring component includes an integrally formed first insertion part, a plugging head part, a pin and a wire part. The first insertion part is adapted to the deformation cavity and is inserted into the elastic rubber tube. The plugging head part is located outside the elastic rubber tube and abuts against the elastic rubber tube. There are two pins which are respectively located on both sides of the insertion part. The pins respectively correspond to the conductive wires and are inserted into the conductive rubber strips. The wire part is electrically connected to the pins.

[0018] After adopting the above technical solution, the beneficial effects of the present utility model are as follows:

[0019] (1) For this safety touch anti-collision strip, when subjected to external pressure or impact, the elastic rubber tube will deform, causing the two conductive rubber strips to come into contact, thereby enabling the detection of external pressure or impact signals. Moreover, the elastic rubber tube has a flat structure, and the two conductive rubber strips are respectively located at the top and bottom inside the elliptical tube hole of the elastic rubber tube, making it easier to achieve the contact conduction of the two conductive rubber strips, with high detection sensitivity.

[0021] (3) The opposite side of the conductive rubber strip has an arc-shaped structure, making the middle distance between the cross-sections of the two conductive rubber strips smaller than the edge distance. When subjected to external pressure or impact, the two conductive rubber strips are more likely to come into contact, with higher detection sensitivity; when subjected to external pressure or impact, the elastic rubber tube deforms, causing the two conductive rubber strips to come into contact. At this time, the two conductive rubber strips at the position where the external pressure or impact is received divide the deformation cavity into two independent parts, presenting an ∞ shape.

The copper foil wire and silver foil wire are wound around the bulletproof wire, greatly improving the electrical conductivity of the conductive wire, and having good toughness and anti-yield strength, thereby greatly improving the detection sensitivity and service life of this safety touch anti-collision strip.

[0023] (5) The wiring component provided at the end of the elastic rubber tube. During use, align the first insertion part with the deformation cavity of the elastic rubber tube and the insertion pin with the conductive wire, insert the wiring component into the end of the elastic rubber tube, and use glue to bond and fix the plugging part to the end of the elastic rubber tube, then the wiring connection of this safety touch anti-collision strip can be achieved, making the wiring operation of this safety touch anti-collision strip simple and convenient.

[0024] (6) The plug head has a protective edge. After the wiring component is installed, the protective edge wraps the elastic rubber tube, providing good waterproof performance.

[0025] (7) A tube end plug is provided, which facilitates separating two conductive wires. During use, the tube end plug is installed at the end of the elastic rubber tube, and then the conductive wires are connected to the wires. After that, the assembled component with the wiring completed is placed into an injection molding device, and a waterproof plug head is obtained through the injection molding process. Since the waterproof plug head wraps the wiring ends of the conductive wires and the wires, good sealing of the wiring ends is achieved, and the waterproof plug head is integrally formed with the wires and the elastic rubber tube. Therefore, it has better waterproof performance, achieving complete waterproof sealing and greatly extending the service life of the safety touch anti-collision strip. Description of the Drawings

There is a gap between the two conductive rubber strips 2, and a deformation cavity 4 is formed by enclosing between the conductive rubber strips 2 and the elastic rubber tube 1.

When this safety touch anti-collision strip is installed and used, the side with the strip-shaped protrusion 101 faces outward.

When subjected to external pressure or impact, the elastic rubber tube 1 deforms, causing the two conductive rubber strips 2 to come into contact. At this time, the two conductive rubber strips 2 at the position where the external pressure or impact is received divide the deformation cavity 4 into two independent parts, presenting an ∞ shape.

The first insertion part 501 is adapted to the deformation cavity 4 and is inserted into the elastic rubber tube 1. The plugging head part 502 is located outside the elastic rubber tube 1 and abuts against the elastic rubber tube 1. Two plug pins 503 are provided and are respectively located on both sides of the insertion part. The plug pins 503 respectively correspond to the conductive wires 3 and are inserted into the conductive rubber strip 2. The wire part is electrically connected to the plug pins 503. When installing the wiring member 5, align the first insertion part 501 with the deformation cavity 4 of the elastic rubber tube 1 and align the plug pins 503 with the conductive wires 3, then insert the wiring member 5 into the end of the elastic rubber tube 1, and use glue to bond and fix the plugging head part 502 to the end of the elastic rubber tube 1, then the wiring connection of the safety touch anti-collision strip can be realized, making the wiring operation of the safety touch anti-collision strip simple and convenient.

[0051] In one embodiment, as Figure 9 and Figure 11 show, the side of the plugging head part 502 facing the elastic rubber tube 1 has a protective edge 5021. The protective edge 5021 encloses to form a slot adapted to the outer contour of the elastic rubber tube 1, and the protective edge 5021 wraps the elastic rubber tube 1. The plugging head part 502 having the protective edge 5021, after the wiring member 5 is installed, the protective edge 5021 wraps the elastic rubber tube 1, having good waterproof performance.
